Description

  The present invention relates to a security device including a setting operation unit for performing various setting operations related to security in a main body case, such as a home controller of a security system.

  A security system provided in a building such as a house is constructed by providing various sensors and switches for disaster prevention and crime prevention in each part of the building, and providing a home controller for overall management of each sensor. . The home controller as a security device is configured by arranging various devices such as a circuit board mounted with a control circuit in a thin box-shaped main body case, but the door provided in the main body case is opened. By doing so, a setting operation unit for performing various setting operations relating to security is exposed, and operation and maintenance of the setting operation unit can be performed.

  In this case, the door is mechanically locked in a closed state during normal operation so that the setting operation unit is not illegally operated, and only a person who has a proper key operates the mechanical lock to open and close the door. Can be done. In addition, a door open / close detection sensor is provided to deal with cases in which a door is illegally opened by a bandit, etc., and a security management company (security company) or the police will be notified if the door is opened. Has been made. However, in this configuration, when a security engineer's service person opens the door for maintenance, etc., the user may forget the operation to disable the function of the door open / close detection sensor. There was a risk of it.

On the other hand, for example, in the field of house doors and automobiles, personal ID authentication using an IC card and personal authentication using fingerprint verification are performed, and unlocking of a house door using a key is performed only when regular personal authentication is performed. An electronic security system that allows (opening / closing of an automobile door or starting an engine) has been considered (see, for example, Patent Document 1). When this technology is applied to the security device described above, the function of disabling the function of the door opening / closing detection sensor and enabling the door opening operation with a key based on personal authentication using an IC card or the like Can be considered. According to this, it is possible to obtain high security while preventing the occurrence of false alarms during maintenance or the like.

  By the way, in this type of security device, functions (items) that can be set and operated by the setting operation unit can be easily set by a user operation, such as a partial change of data when the number of family members changes. There are various types from a level that can be set to a high level that can only be set by a professional serviceman of a security management company, for example, accompanied by a program change.

  From the viewpoint of security, the former and the latter are completely different in importance. Compared to the function that can be set and operated by the former user, the latter function may be seriously damaged if operated illegally by a bandit for the purpose of unauthorized entry into the building or theft. Yes, sufficiently high security is required.

  Conventionally, for functions that can be set and operated by the setting operation unit, functions that can be set by general users and functions that require the knowledge of dedicated service personnel are handled equally in terms of security. The following problems occurred. For example, as described above, a combination of personal authentication using an IC card and unlocking using a dedicated key results in an unnecessarily high level of security with respect to functions that can be set by general users. become.

  In this case, it is necessary to strictly manage the two members of the IC card and the dedicated key. However, forcing a general user to perform such strict management is harsh, and there is a risk that they may be lost or stolen. It will be big. On the other hand, there is also a problem that a setting operation that should be restricted by an ordinary user can be performed for an item that requires knowledge corresponding to a professional service person. . In other words, if it is a function that can be set and operated by a general user, the security level should be set in consideration of the balance between workability and security according to the operation content of each target. It is desirable to provide security according to the security level, such as causing adverse effects.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to enable operation of a setting operation unit by opening a door provided in a main body case, and a plurality of setting operations that can be performed by a setting operation unit. It is in providing the security apparatus which can provide the security property according to those security levels regarding the function of (1).

In order to achieve the above object, a security device according to the present invention comprises a main body case including first and second setting operation units having different security levels, and opens and closes the main body case. A first door which is provided and opened so that the first setting operation unit can be operated; and a first notification means for detecting and notifying that the first door is opened; A first locking means for locking the first door in a closed state, an authenticating means for authenticating an individual who is permitted to operate the first setting operation section, and a normal authentication by the authenticating means. Based on what has been done, the first control means for unlocking the first locking means and disabling the first reporting means, and the first door is opened in the main body case. Open / close operation is possible on condition that A second door that allows the second setting operation unit to be operated by being opened, a second notification means for detecting that the second door is opened, and a key; an insertion opening, the dedicated key of the second of the be those individuals operation is permitted in the setting operation unit possessed personal authentication of the separate member from the member is inserted into the said key insertion opening A second lock means that allows the second door to be opened and closed in a closed state, a dedicated key determination means that determines that the dedicated key is inserted into the key insertion slot, and a dedicated key determination means And a second control means for invalidating the second notification means based on the determination that the dedicated key is inserted (invention of claim 1).

  According to this, at the normal time, the first door provided in the main body case is locked in the closed state by the first locking means, and the first setting operation unit cannot be operated. Moreover, since the 1st door is locked in the obstruction | occlusion state, the 2nd door will be in the obstruction | occlusion state and operation of the 2nd setting operation part is also impossible. At this time, when the first door is pry open, it is detected and notified by the first reporting means. When the second door is pry open, it is detected and notified by the second reporting means.

  When an individual who is permitted to operate the first setting operation unit opens the first door and wants to perform setting operation or maintenance of the first setting operation unit, the individual authentication is performed. Is normally performed by the authentication means, the first control means releases the lock by the first locking means and the first reporting means is invalidated. Therefore, the individual can open the first door and operate the first setting operation unit, and at this time, erroneous notification is prevented in advance.

  When an individual who is permitted to operate the second setting operation unit and possesses a dedicated key opens the second door and wants to perform setting operation or maintenance of the second setting operation unit The second door can be opened and closed by inserting the dedicated key into the key insertion port of the second locking means after the first door is opened. At the same time, when the dedicated key determining means determines that the dedicated key is inserted into the key insertion slot, the second control means invalidates the second reporting means.

  Accordingly, a person who is permitted to operate the second setting operation unit can open the second door and operate the second setting operation unit, and at this time, an erroneous report may be made. Prevented in advance. When the first door is opened and a person who does not have a dedicated key (the operation of the second setting operation unit is not permitted) attempts to open the second door by picking or the like. Is notified by the second reporting means.

  As a result, the opening of the first door, that is, the setting operation of the first setting operation unit is permitted only by personal authentication, so that a certain security can be obtained while the IC for authentication is temporarily provided. Even when a member such as a card is possessed, only one member should be managed. On the other hand, regarding the opening of the second door, that is, the setting operation of the second setting operation unit, both the personal authentication and the dedicated key authentication are performed, so that the second reporting means can be invalidated, and high security is achieved. Can be obtained.

  As a result, according to the present invention, for example, a general user or the like permits only the operation of the first setting operation unit, and a serviceman or the like of the security management company operates and operates the first setting operation unit. By permitting both operations of the second setting operation unit, it is possible to share (limit) the functions according to the level of personal knowledge, etc., for a plurality of functions that can be set and operated by the setting operation unit, In addition, by setting these functions separately for the first setting operation unit and the second setting operation unit according to the importance of security, security according to the security level can be obtained. Can be granted.

  As an authentication means for performing personal authentication, personal authentication based on reading ID data recorded on an IC card or an RF tag by communication using electromagnetic waves, or a bar code or two-dimensional code is optically used. Various methods such as those that perform authentication based on reading, biometric recognition using fingerprints, finger veins, irises, voiceprints, and the like can be employed.

  In addition, as a configuration for providing the second door so that it can be opened and closed on the condition that the first door is in an open state, a so-called double door in which the second door is provided inside the first door. It can be set as a door structure. Alternatively, while the first door and the second door are provided in parallel, when the first door is closed, the cover provided on the first door covers the key insertion slot and the dedicated key is inserted. A configuration such as prohibition is also possible.

  In the present invention, the dedicated key determination means includes two protrusions provided on the shoulder portion of the dedicated key knob in the state where the dedicated key is inserted into the key insertion slot in the vicinity of the key insertion slot. And two authentication switches that are pressed by each of the two, and when the two authentication switches are simultaneously pressed, it is determined that the dedicated key is inserted into the key insertion slot. (Invention of claim 2) Thereby, the dedicated key determination means can be realized with a relatively simple configuration, and the safety against picking can be improved.

  In the present invention, a lid member that closes and opens the key insertion opening, an opening detection sensor that detects that the lid member is opened, and the opening detection sensor detects opening. A third reporting unit that reports when the dedicated key determining unit does not determine that the dedicated key is inserted can be provided (invention of claim 3). This is an effective measure against picking.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 2, a security device (for example, a home controller of a security system) 1 according to the present embodiment has a security function as described later in a body case 2 having a thin rectangular box shape made of, for example, a synthetic resin. Various electronic parts (control circuit) for realizing are incorporated. The main body case 2 is configured by combining a lower case 2a whose front surface (upper surface in the drawing) is opened and an upper case 3 serving as a first door that covers the opening of the lower case 2a so as to be openable and closable.

  Although not shown in detail, the security system provided in the building is provided with various sensors for disaster prevention and crime prevention (various security sensors 4 shown in FIG. 1) in each part of the building, and these various security sensors. 4 is provided with a security device (home controller) 1 for overall management. In this case, the security device 1 is attached to, for example, a wall of a building with the upper case 3 side as the front surface. However, in the following description, when referring to the vertical and horizontal directions, FIG. This state (state with the upper case 3 side as the upper surface) will be described as a reference.

  As shown in FIG. 2, the upper case 3 is rotatably connected to the lower case 2a via a hinge portion (not shown) provided on the left side portion 3a in FIG. The portion 3b is normally locked in a closed state by an electric lock 5 as a first locking means provided in the lower case 2a. As will be described later, the personal lock 5 (authentication using an IC card in this embodiment) automatically unlocks the electric lock 5 so that the upper case 3 can be opened and closed. ing. At this time, a first door sensor 6 (shown only in FIG. 1) for detecting the open / closed state of the upper case 3 with respect to the lower case 2a is provided in the main body case 2.

  In the main body case 2 (inner bottom portion of the lower case 2a), a rectangular inner box 7 that is slightly smaller than the lower case 2a is provided, which is a double box shape. An opening 7b is formed in the upper wall portion 7a constituting the upper surface in the figure of the inner box 7 except for the right side portion in the drawing, and as a second door for closing the opening 7b so as to be opened and closed. An inner door 8 is provided. In addition, a user operation unit 9 as a first setting operation unit is provided on the upper wall portion 7a of the inner box 7.

  Although not shown in detail, the user operation unit 9 includes a plurality of keys such as a numeric keypad, a display unit, and the like, and a part of all functions that can be set and operated in the security device 1 by the operation. For example, it is possible to set items (functions) that can be set by the user (allowed to be set by the user) such as partial change of data and change of PIN when there is a change in the number of family members. Has been. The user operation unit 9 can be operated by opening the upper case 3 with respect to the lower case 2a. Further, the opening / closing operation of the inner door 8 is enabled on condition that the upper case 3 is opened with respect to the lower case 2a.

  The inner door 8 is rotatably connected to the inner box 7 via a hinge 10 provided on the left side in FIG. 2, and the right side is provided in the inner box 7. The second lock means 11 is locked and unlocked by a mechanical lock 11. The mechanical lock 11 normally locks the inner door 8 in a closed state, and as shown in FIG. 3, a regular dedicated key 13 is inserted into a key insertion opening 12 provided in the upper wall portion 7a. Thus, the lock is released and the inner door 8 can be opened and closed. The configuration of the key insertion slot 12 will be described later. In the inner box 7, a second door sensor 14 (shown only in FIG. 1) for detecting the open / closed state of the inner door 8 is provided.

  As shown in FIG. 1, the inner box 7 includes a CPU (microcomputer) 15a and controls the entire control circuit 15, an authentication device 16 serving as authentication means, for example, via a telephone line. A communication device 17 that performs communication (report), a setting operation unit 18 as a second setting operation unit, and the like are provided. Among them, the authentication device 16 performs authentication of an individual who is permitted to operate the user operation unit 9, and in this embodiment, is constituted by a known non-contact IC card reader.

  At this time, an individual who is permitted to operate the user operation unit 9, that is, a user (a master (family) of the house), a serviceman of a security management company, or the like, has stored a unique ID data. IC card 19 is provided. The authentication device 16 generates a magnetic field for communication in a communication area provided on the front side of the main body case 2, supplies power to the IC card 19 that is in close proximity, and receives radio waves returned from the IC card 19. Then, the ID data recorded on the IC card 19 is read to perform personal authentication. At this time, the ID data (data for verification) of the personal IC card 19 permitted to operate the user operation unit 9 is registered (stored) in the memory of the authentication device 16 (or the control circuit 15) in advance. Of course. Note that it is possible to distinguish between a user and a serviceman based on the ID data (data for verification) at this time.

  The communication device 17 is controlled by the control circuit 15, and when an abnormality is detected by the security sensor 4 described above, the center of a security management company (further, police, fire fighting, first aid, etc.) via a telephone line. To report to. In this case, a notification is made when an intrusion of a suspicious person into a building (site), a fire, or a gas leak is detected, and of course, the first door sensor 6 is valid ( When the first door sensor 6 detects the opening of the upper case 3 in a state that is not invalidated), a notification is made based on the input of the signal to the control circuit 15. Yes.

  Accordingly, the first door sensor 6, the control circuit 15, the communication device 17, and the like constitute first notification means for detecting and reporting that the upper case 3 has been opened. Similarly, when the second door sensor 14 detects the opening of the inner door 8 in a state where the second door sensor 14 is enabled (not disabled), the signal is controlled. A notification is made based on the input to the circuit 15. Therefore, the second door sensor 14, the control circuit 15, the communication device 17, and the like constitute second notification means for detecting and reporting that the inner door 8 has been opened.

  The setting operation unit 18 is configured to set the items (functions) that are most important for security among the functions that can be set and operated in the security device 1, such as changing the program of the control circuit 15 or important data. It is provided to perform setting operations that can only be performed by a professional serviceman of the security management company (which other users such as users must not do). As shown in FIG. 2, the setting operation unit 18 can be operated with the inner door 8 opened with respect to the inner box 7. Further, maintenance of the control circuit 15, the authentication device 16, the communication device 17, and the setting operation unit 18 can be performed with the inner door 8 opened.

  Here, the configuration of the key insertion slot 12 portion of the mechanical lock 11 that locks the inner door 8 will be described with reference to FIG. As shown in FIG. 3 (a), the dedicated key 13 has a flat plate shape integrally including a knob 13a and a blade 13b extending from the knob 13a toward the tip, and is formed on both side edges of the blade 13b. Convex portions 13c and 13c that are convex outward are provided. Further, on both sides of a so-called shoulder portion of the knob 13a, two projecting portions 20 and 20 projecting toward the tip side are integrally provided. The dedicated key 13 is held only by a person who is permitted to operate the setting operation unit 18, for example, a professional serviceman of a security management company.

  On the other hand, the key insertion port 12 is formed in a slit hole shape corresponding to the blade 13b of the dedicated key 13, and as shown in FIG. 3A, when the blade 13b is inserted, the convex portion is formed. Recesses 12a and 12a for holding the dedicated key 13 are integrally formed by engaging the respective 13c and 13c. Although not shown in detail, the mechanical lock 11 normally locks the inner door 8 in a closed state (with the dedicated key 13 not inserted into the key insertion opening 12). In the state where the dedicated key 13 is inserted, the inner door 8 is allowed to open and close (the lock is released).

  Further, as shown in FIG. 3B, two authentication switches 21 and 22 corresponding to the two protrusions 20 and 20 are formed in the vicinity of the outside on both sides in the longitudinal direction of the key insertion slot 12. Is provided. These authentication switches 21 and 22 are configured to include, for example, a piezoelectric element, and are pressed by the protrusions 20 and 20 when the dedicated key 13 is inserted into the key insertion slot 12, whereby the control circuit A pressing operation signal is output to 15. The control circuit 15 determines that the dedicated key 13 is inserted into the key insertion slot 12 when the two authentication switches 21 and 22 are simultaneously pressed (turned on). Dedicated key determination means is composed of the two authentication switches 21, 22 and the control circuit 15. Note that the key insertion slot 12, the authentication switches 21, 22 and the like may be provided on the inner door 8 side.

  FIG. 1 schematically shows an electrical configuration of the security device 1 according to the present embodiment, centering on the control circuit 15. The control circuit 15 is connected to the various security sensors 4, electric lock 5, user operation unit 9, authentication device 16, communication device 17, and setting operation unit 18, and controls them. The control circuit 15 receives detection signals from the first door sensor 6, the second door sensor 14, and the two authentication switches 21 and 22.

  At this time, as will be described in detail later in the description of the operation (flowchart description), the control circuit 15 performs overall processing of the entire security system by the software (execution of the control program) and the following. Each process is executed to perform various functions. That is, at normal times (when the security device 1 is powered on), the control circuit 15 locks the electric lock 5 and enables both the first door sensor 6 and the second door sensor 14. Further, the authentication device 16 is in a standby state (communication standby state), and always generates a magnetic field (request signal) in a communication area where communication with the IC card 19 in front of the upper case 3 is possible. I am letting.

  Therefore, in this state, if the first door sensor 6 detects the opening of the upper case 3, the communication device 17 notifies the center of the security management company (first notification means). On the other hand, a user or a service person who is permitted to operate the user operation unit 9 holds his IC card 19 in the vicinity of the upper case 3 to perform reading by the authentication device 16 and collates with the read ID data. If any one of the ID data matches and the regular personal authentication is performed, the control circuit 15 unlocks the electric lock 5 and invalidates the first door sensor 6 (open detection). Do not report even if there is a signal). Thus, the function as the first control means is realized.

  After the above personal authentication, the upper case 3 is opened, and in this state, it is further determined that the authorized dedicated key 13 is inserted into the key insertion slot 12 based on the detection signals from the authentication switches 21 and 22. In such a case, the control circuit 15 disables the second door sensor 14 (does not report even if there is an open detection signal). Thus, the function as the second control means is realized.

  Next, the operation of the above configuration will be described with reference to FIGS. As described above, the user who is permitted to operate the user operation unit 9 is provided with the IC card 19 for authentication. Further, a professional serviceman of the security company is permitted to operate the user operation unit 9 and the setting operation unit 18. For example, when visiting the user's house, the IC card 19 and the inner door 8 for authentication are used. It has a dedicated key 13 for opening.

  The flowcharts of FIGS. 4 to 7 show the procedure of processing executed by the control circuit 15 when the user or serviceman performs the setting operation of the user operation unit 9 or the setting operation unit 18. 4 to 7 are originally one continuous flowchart, but are divided into four parts for the convenience of the drawing space. First, the flowchart of FIG.4 and FIG.5 has shown the process sequence in case a user mainly operates the user operation part 9 and performs a setting (change).

  That is, as shown in FIG. 4, when the security device 1 is turned on, the first door sensor 6 and the second door sensor 14 are validated in step S1, and the authentication device 16 is validated in step S2. Is in a standby state (a state in which a request signal is intermittently output). The first door sensor 6 and the second door sensor 14 being effective means that a notification is made when the sensors 6 and 14 detect the opening of the upper case 3 and the inner door 8. “Disable” means that the notification is not performed even if the opening of the upper case 3 and the inner door 8 is detected.

  In step S <b> 3, whether or not the upper case 3 is opened with respect to the main body case 2 is monitored by the first door sensor 6. In the normal state, the upper case 3 is locked in the closed state by the electric lock 5. If the first door sensor 6 detects the opening of the upper case 3 (Yes in step S3), it is the upper case. It can be determined that the case 3 is abnormally forcibly opened or the like, and in step S4, a report is made to a security company or the like via the communication device 17. If the opening of the upper case 3 is not detected (No in step S3), whether or not the IC card 19 has entered the communication area by the authentication device 16 (IC card reader) in the next step S5. Is constantly monitored.

  Now, when the user or service person wants to perform the setting operation of the user operation unit 9 or the setting operation unit 18, the IC card 19 is raised on the front portion (in the communication area) of the main body case 2. Then, the authentication device 16 recognizes the IC card 19 (Yes in step S5), communicates with the IC card 19 and reads the ID data (step S6). In step S7, the read ID data is compared with the stored ID data for verification. If the authentication is not successful (No in step S7), the read data is discarded in step S8, and the process returns to step S1.

  If the authentication is correctly performed (Yes in step S7), it is determined whether the user is a serviceman or a user in the next step S9. If it is the serviceman ID data (Yes in step S9), the serviceman authentication process ("authentication 1") is performed in step S10, and the process proceeds to step S11. If it is user ID data (No in step S9), the process directly proceeds to step S11. Note that processing when the serviceman operates the setting processing unit 18 will be described later in the description of FIGS. 6 and 7.

  In step S11, the first door sensor 6 is invalidated (notifying is not performed even when opening is detected). At the same time, in step S12, the lock of the upper case 3 by the electric lock 5 is released. Thereby, the user or the service person can open the upper case 3 without fear of reporting. In step S13, it is monitored whether the upper case 3 has been opened. This determination can be made based on the output of the first door sensor 6.

  If the upper case 3 is not opened (No in step S13), in the next step S14, it is determined whether or not a certain time (for example, several minutes) has elapsed after the lock by the electric lock 5 is released. The If the upper case 3 is not opened even after a predetermined time has elapsed (Yes in step S14), the upper case 3 is locked again in the closed state by the electric lock 5 in step S15, and the process returns to step S1. . If the upper case 3 is opened before the predetermined time elapses (Yes in step S13), the ID data of the IC card 19 read in step S16 is discarded, and the process proceeds to step S17 in FIG.

  Proceeding to FIG. 5, in step S <b> 17, it is determined whether or not the dedicated key 13 is inserted into the key insertion slot 12. This determination can be made based on the outputs of the authentication switches 21 and 22. If the dedicated key 13 is inserted into the key insertion slot 12 (Yes in step S17), the process proceeds to step S30 in FIG. 6, but this process will be described later.

  If the dedicated key 13 is not inserted into the key insertion slot 12 (No in step S17), whether or not the inner door 8 has been opened based on the detection of the second door sensor 14 in step S18. To be judged. At this time, if the opening of the inner door 8 is detected without the dedicated key 13 being inserted into the key insertion slot 12 (Yes in step S18), it is an abnormality such as the inner door 8 being forcibly opened. In step S4, a report is made to the security company or the like via the communication device 17.

  If the inner door 8 is not opened (No in Step S18), it is determined in Step S19 whether or not the upper case 3 has been closed based on the detection of the first door sensor 6. When the upper case 3 is closed without performing the operation of the user operation unit 9 (Yes in Step S19), the process proceeds to Step S15, the electric lock 5 is locked, and the process returns to Step S1. If upper case 3 is not closed (No in step S19), it is determined in step S20 whether or not there is an operation of user operation unit 9. Here, the user or the service person operates the user operation unit 9, for example, among the functions that can be set and operated in the security device 1 such as partial change of data when the number of family members is changed. A relatively simple level setting operation is possible.

  When the user operation unit 9 is not operated (No in Step S20), a predetermined time (for example, several minutes) has elapsed since the opening of the upper case 3 is detected in Step S21 (Yes in Step S13). It is judged whether or not. If the predetermined time has not elapsed (No in step S21), the process returns to step S17. If the user operation unit 9 is not operated even after a predetermined time has elapsed (Yes in step S21), a notification that prompts the user to operate the user operation unit 9 is given in step S22.

  If the user operation unit 9 is operated after this notification is made (Yes in step S23), the process proceeds to step S25. If the user operation unit 9 is not yet operated, it is determined whether or not the upper case 3 is closed in step S24. If the upper case 3 is closed (Yes in step S24), the process proceeds to step S15. Then, after the electric lock 5 is locked, the process returns to step S1. If the upper case 3 is not closed (No in step S24), the upper case 3 is left open for a relatively long period of time, so the process proceeds to step S4 and an abnormality is reported. The

  When the user or the serviceman operates the user operation unit 9 (Yes in step S20 or Yes in step S23), a setting process corresponding to the operation is performed in step S25. When the operation is completed, the user or serviceman performs an operation indicating that the operation has been completed in the user operation unit 9. If the operation has not been completed yet (No in step S26), step S17 is performed. Return to. When the operation is completed (Yes in step S26), the setting contents are stored in the memory in step S27.

  In step S28, it is determined whether or not the upper case 3 is closed. If the upper case 3 is closed (Yes in step S28), the process proceeds to step S15, and the electric lock 5 is locked. Return to S1. If upper case 3 cannot be closed (No in step S28), it is determined again in step S29 whether or not user operation unit 9 has been operated. If there is an operation (Yes in step S29). ), The process from step S25 is repeated. If there is no operation (No in step S29), the process returns to step S17.

  Thus, at the normal time, when the upper case 3 is locked by the electric lock 5 and the upper case 3 is forcibly opened, the notification based on the detection of the first door sensor 6 is surely performed. It becomes like this. Then, the user or serviceman who possesses the legitimate IC card 19, that is, the user or service person who is permitted to operate the user operation unit 9 performs personal authentication using the IC card 19 to unlock the upper case 3. In addition, since the notification based on the detection by the first door sensor 6 is invalidated, the user operation unit 9 can be operated to perform a desired setting operation (of a type allowed by the user). Of course, false reports can be prevented.

  6 and 7 (processes after step S30) show a processing procedure when a serviceman specialized in a security company operates the setting operation unit 18 to perform setting or the like. Here, when the service person possessing the dedicated key 13 wants to operate the setting operation unit 18, the dedicated key 13 is inserted into the key insertion slot 12 as described above (step S17 in FIG. 5). Yes). Then, in step S30, it is determined whether or not the two authentication switches 21 and 22 are pressed simultaneously.

  At this time, if the regular dedicated key 13 is inserted into the key insertion slot 12 as described above, the two authentication switches 21 and 22 are simultaneously pressed by the protrusions 20 and 20 (ON). Therefore, it is determined that the regular dedicated key 13 is inserted (Yes in step S30), and an authentication process (authentication 2) to the effect that the dedicated key 13 is used is performed in step S33.

  On the other hand, if the two authentication switches 21 and 22 are not on at the same time (No in step S30), it is determined that the authentication has failed in step S31, and the inner door 8 has been opened in step S32. Judgment is made. If the inner door 8 has been opened (Yes in step S32), it is determined that the inner door 8 has been opened illegally, the process proceeds to step S4, and an abnormality notification is made. If the inner door 8 cannot be opened (No in step S32), the process returns to step S17 in FIG.

  When the authentication process (authentication 2) in step S33 is performed, it is determined in step S34 whether authentication 1 (step S10 in FIG. 4) has been completed. In this case, only when the upper case 3 is opened, the user uses the IC card 19 possessed by the user, and the authentication 1 is not completed in a case where the user tries to replace the work with the service person after that. . If the authentication 1 has not been completed (No in step S34), a notification that prompts card authentication is made in step S35, and whether or not the IC card 19 has been read by the authentication device 16 in the next step S36. Is judged.

  When the IC card 19 possessed by the serviceman is read (Yes in step S36), it is determined in step S37 whether the read ID data is ID data for the serviceman. If it is ID data for a service person (Yes in step S37), an authentication process (authentication 1) is performed in step S38, and the process proceeds to step S40. On the other hand, if the IC card 19 is not read (No in step S36) or the authentication of the IC card 19 ends abnormally (No in step S37), the process proceeds to step S39. A determination is made whether the door 8 has been opened. If the inner door 8 has been opened (Yes in step S39), it is determined that the inner door 8 has been opened illegally, the process proceeds to step S4, and an abnormality notification is made. If inner door 8 cannot be opened (No in step S39), the process returns to step S35.

  If the authentication 1 has already been completed (Yes in step S34) and if the authentication process (authentication 1) has been performed in step S38, the second door sensor 14 is disabled in the next step S40. (No notification is made even if the opening of the inner door 8 is detected). Thereby, the service person can open the inner door 8 without fear of reporting. In the next step S41, it is monitored whether or not the inner door 8 has been opened. This determination is made based on the output of the second door sensor 14.

  When the service person opens the inner door 8 (Yes in step S41), it is determined in step S42 whether or not the dedicated key 13 is inserted into the key insertion slot 12. If the dedicated key 13 is removed from the key insertion slot 12 at this time (No in step S42), the operation proceeds to step S4 as an illegal operation, and an abnormality is reported. If the dedicated key 13 is inserted into the key insertion slot 12 (Yes in step S42), it is determined in step S43 whether or not the setting operation unit 18 is operated. Here, the service person operates the user setting operation unit 18 to perform setting operation, maintenance, etc. of matters (functions) that are most important for security, for example, accompanied by a change in the program of the control circuit 15 or important data. Is possible.

  If the service person has operated the setting operation unit 18 (Yes in step S43), the setting process corresponding to the operation is performed in step S46, and the process proceeds to step 47. When there is no operation of setting operation part 18 (No in Step S43), it progresses to Step S47 as it is. When the operation is completed, the service person performs an operation indicating that the operation has been completed in the setting operation unit 18, and when the operation has not been completed (No in step S47), the service man proceeds to step S44. .

  In step S44, it is determined whether the inner door 8 has been closed. If inner door 8 is not closed (No in step S44), the process returns to step S42. On the other hand, when the inner door 8 is closed (Yes in step S44), in step S45, the service person is notified that the process (operation of the setting operation unit 18) is incomplete, and step Return to S40.

  On the other hand, when the operation is completed (Yes in step S47), the process proceeds to step S48 in FIG. 7, and the setting contents are stored in the memory. In step S49, it is determined whether the inner door 8 is closed. If the inner door 8 is closed (Yes in step S49), whether the dedicated key 13 has been removed from the key insertion slot 12 in step S50. Judgment is made. If the upper key 3 is closed (No in Step S51) with the dedicated key 13 not removed (No in Step S50), it is forgotten to remove the dedicated key 13, so in Step S52, A notification that the user has forgotten to pull out the dedicated key 13 is made, and the process returns to step S50. In this case, since the upper case 3 is not yet locked, the service person can open the upper case 3 and remove the dedicated key 13.

  When the dedicated key 13 is removed from the key insertion slot 12 (Yes in Step S50), the second door sensor 14 is validated in Step S53. In step S54, it is monitored whether or not the upper case 3 is closed. If the upper case 3 is closed (Yes in step S54), the electric lock 5 is locked in step S55, and then the step S1 is performed. Return to.

  Thus, even after the upper case 3 is normally opened, only a service person who has the dedicated key 13, that is, the operation of the setting operation unit 18 is permitted to use the dedicated key 13 with the key insertion slot 12. Since the notification based on the detection of the second door sensor 14 can be invalidated and the inner door 8 can be opened, and the setting operation unit 18 can be operated to perform a professional setting operation. is there. Of course, when there is an unauthorized operation of the inner door 8, a report is surely made and an erroneous report can be prevented.

  As described above, according to the security device 1 of the present embodiment, the opening of the upper case 3, that is, the setting operation of the user operation unit 9 is permitted only by the personal authentication by the IC card 19. However, the member to be managed by the user is only one IC card 19. On the other hand, regarding the opening of the inner door 8 provided in the main body case 2, that is, the setting operation of the setting operation unit 18, both personal authentication (authentication 1) using the IC card 19 and authentication (authentication 2) using the dedicated key 13 are performed. As a result, the second door sensor 14 (second notification means) can be invalidated, and high security can be obtained.

  As a result, according to the present embodiment, only the operation of the user operation unit 9 is permitted for the user, and the operation of the user operation unit 9 and the operation of the setting operation unit 18 are permitted for the professional serviceman of the security management company. By permitting both, it is possible to share (limit) the functions according to the level of personal knowledge and the like for a plurality of functions that can be set and operated. In addition, by setting the functions separately for the user operation unit 9 and the setting operation unit 18 according to the importance of security, it is possible to provide security according to the security level. it can.

  Further, particularly in this embodiment, two authentications that are pressed by the two protrusions 20 and 20 in the vicinity of the key insertion slot 12 with the dedicated key 13 inserted in the key insertion slot 12. Since the switches 21 and 22 are provided and when the two authentication switches 21 and 22 are simultaneously pressed, it is determined that the dedicated key 13 is inserted into the key insertion slot 12. The determination means can be realized with a relatively simple configuration, and the merit that safety against picking can be improved can be obtained.

  FIG. 8 shows another embodiment of the present invention. This embodiment is different from the above embodiment in the configuration of the key insertion slot 12 provided on the upper wall portion 7a of the inner box 7. is there. That is, in this embodiment, a rectangular plate-like lid member 31 is provided on the lower surface side (back surface side) of the key insertion port 12 so as to be openable and closable. The lid member 31 is pivotally supported on the left side in the figure on the lower surface side of the upper wall portion 7a, and is provided so as to be capable of rotating (opening and closing) in the direction of arrow A and in the opposite direction. The key insertion port 12 is biased in the direction of closing (the direction opposite to the arrow A).

  The dedicated key 13 (not shown) is inserted into the key insertion opening 12 while pushing the lid member 31 in the direction of arrow A against the spring force of the spring 32 (rotating). It has become. The upper wall portion 7a is provided with authentication switches 21 and 22 located on both longitudinal sides of the key insertion slot 12 (front and rear both sides in the figure). A pressing operation is also possible from the back side of the upper wall 7a.

  On the other hand, the lid member 31 is integrally provided with protrusions 33 and 33 (only one is shown in FIG. 8B) for turning on the authentication switches 21 and 22, respectively. . Therefore, as shown in FIG. 8B, in the state where the lid member 31 closes the key insertion opening 12, each projection 33, 33 pushes each authentication switch 21, 22 to turn it on. When the member 31 is opened, the protrusions 33 and 33 are separated from the authentication switches 21 and 22 and turned off. Accordingly, in addition to functioning as dedicated key determination means, the authentication switches 21 and 22 also function as opening detection sensors that detect that the lid member 31 has been opened.

  The control circuit 15 to which the signals from the authentication switches 21 and 22 are input, the normal state, that is, in the state where the dedicated key 13 is not inserted into the key insertion slot 12, the authentication switches 21 and 22 are By being turned on, it is determined that the lid member 31 is in a closed state. On the other hand, when the regular dedicated key 13 is inserted into the key insertion slot 12, the authentication switches 21 and 22 are temporarily turned off by the rotation of the lid member 31, but immediately after that, the protrusion of the dedicated key 13 is turned off. Since the authentication switches 21 and 22 are simultaneously turned on by the units 20 and 20, it can be determined that the regular dedicated key 13 has been inserted.

  On the other hand, if the state where the authentication switches 21 and 22 are turned off may continue for a predetermined time, a member (another key or tool) other than the regular dedicated key 13 is inserted into the key insertion slot 12. In such a case, the control circuit 15 determines that the dedicated key has been inserted by the dedicated key determination means (although the opening detection sensor detects the opening of the lid member 31). Report to the security company. Accordingly, the control circuit 15 and the communication device 17 make up a third notification means. Thus, an effective measure against picking can be provided, and the authentication switches 21 and 22 are also used as open detection sensors. Therefore, a separate sensor is unnecessary and a simple configuration can be achieved.

  In the above-described embodiment, a method of reading the ID data of the IC card 19 by a non-contact type card reader (authentication device 16) is adopted as an authentication means for performing personal authentication. Those that authenticate individuals based on communication with RF tags and mobile phones, those that authenticate based on optical reading of barcodes and two-dimensional codes, fingerprints, finger veins, irises, voiceprints Various methods such as biometric recognition using the above can be employed.

  Moreover, in the said Example, although it was set as the structure which provides the inner door 8 inside the upper case 3 (inside the main body case 2), the 2nd door is on condition that the 1st door is an open state. The first door and the second door are arranged in parallel, but the cover provided on the first door is inserted into the key when the first door is closed. It is also possible to adopt a configuration in which the insertion of the dedicated key is prohibited while covering the mouth. In addition, the present invention can be implemented with appropriate modifications within a range not departing from the gist.
