Description

  The present invention relates to a crime prevention system that is installed in a building having a window and monitors a suspicious person from entering the window.

  2. Description of the Related Art Conventionally, a crime prevention system is provided that is installed in a building having a window (mainly a house) and monitors a suspicious person from entering the window (for example, see Patent Document 1).

  In the conventional example described in Patent Document 1, various security sensors installed in a house are connected to an interphone master unit, and an alarm is output from the interphone master unit when a crime prevention abnormality is detected by the security sensor. And the window sensor which detects opening and closing and destruction of a window, and the indoor human sensor which detects an intruder in a room using a heat ray etc. are used as a security sensor.

  In this conventional example, when the intercom base unit is set in the alert mode, the alarm sound is generated by receiving a crime prevention abnormal signal from any of the security sensors, and the intercom base unit is set in the non-alert mode. Does not sound an alarm sound even when a security abnormality signal is received from any security sensor.

  In addition, this conventional example is provided with two-stage alert mode setting with different alert levels. In the first vigilance mode with a low vigilance level, only the alarm sound is sounded by the security sensor and the intercom master when a crime prevention abnormality is detected. On the other hand, in the second vigilance mode with a high vigilance level, in addition to sounding the alarm sound when a crime prevention abnormality is detected, notification to the outside is also performed. The first vigilance mode is used when you are at home, and prevents you from making unnecessary reports to the outside if you accidentally open a window or entrance door without releasing the vigilance. be able to. On the other hand, the second alert mode is set when going out, and since it is possible to know a crime prevention abnormality when going out, it is possible to cope with the crime prevention abnormality when going out.

  By the way, during the first alert mode, a window may be opened by a resident who is at home for ventilation or the like. In such a case, an indoor human sensor may detect a resident who passes by the window, and an alarm sound may be generated from the intercom master. On the other hand, if the detection result of the indoor motion sensor is treated as invalid in the alarm mode (first alarm mode) while at home, the intercom master will sound even if a suspicious person enters through the open window. Will not be.

  The present invention has been made in view of the above problems, and an object of the present invention is to prevent a suspicious person from entering while suppressing a false alarm by a resident when a window is opened while at home.

  The crime prevention system of the present invention is a crime prevention system that is installed in a building having a window and prevents a suspicious person from entering through the window, and detects opening / closing of the window or unlocking / unlocking of the lock provided on the window. A first security sensor that transmits the detection result; a second security sensor that detects the presence of a person around the window outside the building and transmits the detection result; the first security sensor and the second security sensor; A security receiver that receives a detection result transmitted from the sensor and issues an alarm according to the detection result, wherein the second security sensor includes a human detection unit that detects the presence of a person within a detection range; Transmission / reception means for transmitting the detection result of the detection means and receiving instructions from the security receiver, alarm means for alarming by sound or light, and transmission / reception when the person detection means detects the presence of a person Means of the detection result A security means for transmitting, wherein the security receiver receives the detection result and transmits the instruction, a warning means for performing a warning by sound, light or external communication, and the transmission and reception Based on the detection result received by the means, it is determined whether or not an alarm is necessary, and when it is determined that an alarm is necessary, the control means for causing the alarm means to issue an alarm and the control means determine whether the alarm is necessary or not. Switching means for selectively switching between a warning mode to be performed and a non-warning mode in which the necessity determination of the alarm is not performed, and the control means detects the presence of a person from the second security sensor in the warning mode. If the detection result of detecting the closed state of the window or the locked state of the lock is received from the first security sensor, the second alarm without warning the alarm means. If the detection result of detecting the open state of the window or the unlocked state of the lock is received from the first security sensor, the instruction to execute the alarm is transmitted to the crime sensor from the transmission / reception means. An alarm means is made to perform an alarm, and the instruction to execute the alarm is transmitted from the transmission / reception means to the second security sensor.

  As shown in FIG. 1, the security system of the present embodiment includes a first security sensor 1, a second security sensor 2, and a security receiver 3. However, in the illustrated example, only one set of the first security sensor 1 and the second security sensor 2 is provided, but a plurality of sets of the first security sensor 1 and the second security sensor 2 may be provided depending on the number of windows. I do not care.

  The first security sensor 1 includes a control unit 10, a window detection unit 11, an antenna 12, a wireless communication unit 13, an alarm unit 14, and the like, and is attached to a fitting (sliding door) 100 that opens and closes a window as shown in FIG. It is attached. The window detection unit 11 detects the locked and unlocked states of the crescent lock 110 provided on the fitting 100, or detects the open and closed states of the fitting 100, and detects the detection state (hereinafter referred to as the window detection state). ) Is detected (for example, when the closed state is changed to the open state), a detection signal is output. However, since such a window detection unit 11 is well known in the art, illustration and description of a detailed configuration are omitted.

  The control unit 10 includes hardware such as a microcomputer, a memory, and a timer, and software such as a program executed by the microcomputer. The control unit 10 outputs a detection signal (detection result) received from the window detection unit 11 to the wireless communication unit 13. The wireless communication unit 13 transmits a wireless signal including the detection result received from the control unit 10 to the security receiver 3 via the antenna 12. The alarm unit 14 includes a speaker and a speaker drive circuit, and sounds an alarm sound (such as a buzzer sound or an alarm message) from the speaker based on an instruction from the control unit 10. However, the alarm unit 14 may output a light alarm instead of the alarm sound or together with the alarm sound.

  The second security sensor 2 includes a control unit 20, a human body detection unit 21, an antenna 22, a wireless communication unit 23, an alarm unit 24, etc., and a window (1) in which the first security sensor 1 is installed as shown in FIG. It is installed on the outer wall surface (outdoor) outside the joinery 100). The human body detection unit 21 detects a person existing around a window (the fitting 100) outdoors by detecting heat rays (infrared rays) emitted from the human body using, for example, a pyroelectric element, and detects a person. A detection signal is output when However, since such a human body detection unit 21 is conventionally known, detailed illustration and description thereof will be omitted.

  The control unit 20 includes hardware such as a microcomputer, a memory, and a timer, and software such as a program executed by the microcomputer. The control unit 20 outputs a detection signal (detection result) received from the human body detection unit 21 to the wireless communication unit 23. The wireless communication unit 23 transmits a wireless signal including the detection result received from the control unit 20 to the security receiver 3 via the antenna 22. The alarm unit 24 includes a speaker and a speaker drive circuit, and sounds an alarm sound (such as a buzzer sound or an alarm message) from the speaker based on an instruction from the control unit 20. However, the alarm unit 24 may output a light alarm instead of the alarm sound or together with the alarm sound.

  The security receiver 3 includes a control unit 30, an antenna 31, a wireless communication unit 32, a storage unit 33, an alarm unit 34, a data communication unit 35, an operation input unit 36, etc., for example, installed on the wall of a living room in the house Is done. The wireless communication unit 32 receives wireless signals transmitted from the first security sensor 1 and the second security sensor 2 via the antenna 31 and outputs a detection result included in the wireless signal to the control unit 30. The control unit 30 stores the detection result received from the wireless communication unit 32 in the storage unit 33 in time series for each of the security sensors 1 and 2. The storage unit 33 is configured by an electrically rewritable nonvolatile semiconductor memory (flash memory or the like). The alarm unit 34 includes a speaker and a speaker drive circuit, and sounds an alarm sound (such as a buzzer sound or an alarm message) from the speaker based on an instruction from the control unit 30. However, instead of the alarm sound, or together with the alarm sound, the alarm unit 34 may output a light alarm. The data communication unit 35 is compliant with a LAN standard such as 100BASE-TX, for example, and performs data communication via a twisted pair cable (LAN cable). Although not shown, the data communication unit 35 is connected to an Internet communication device (such as an optical line termination device <ONU> or a CATV modem) via a LAN cable.

  The operation input unit 36 includes one or more push button switches that are manually turned on. When the push button switch is turned on, the operation input unit 36 receives an operation input corresponding to each push button switch and outputs the operation input to the control unit 30. For example, when a pushbutton switch corresponding to mode switching is turned on, an operation input instructing switching from the warning mode to the non-warning mode or from the non-warning mode to the warning mode is output from the operation input unit 36 to the control unit 30. Upon receiving the operation input, the control unit 30 switches to the non-warning mode if the current mode is the warning mode, and switches to the warning mode if the current mode is the non-warning mode.

  Next, the operation of the crime prevention system of this embodiment will be described with reference to the flowchart of FIG. When receiving the detection result of the human body detection from the second security sensor 2 (S1), the control unit 30 returns to step S1 without doing anything in the non-warning mode. On the other hand, when the warning mode is set (S2), the control unit 30 determines whether the detection result of the window by the first security sensor 1 is an open state or a closed state (S3). If it is in the open state, the control unit 30 causes the radio communication unit 32 to transmit a radio signal including a control command instructing the second security sensor 2 to sound an alarm sound (S5), and further causes the alarm unit 34 to generate an alarm sound. Is sounded (S6). As a result, the control unit 20 of the second security sensor 2 that has received the control command can cause the alarm unit 24 to sound an alarm sound and threaten a suspicious person who is about to enter through the window.

  On the other hand, when the detection result of the first security sensor 1 is in the closed state, the control unit 30 causes the wireless communication unit 32 to transmit a wireless signal including a control command that instructs the second security sensor 2 to sound an alarm sound. (S4), the alarm unit 34 is not sounded.

  In addition, when the operation input unit 36 receives an operation input for stopping the alarm sound while the alarm sound is sounding (S7), the control unit 30 stops the sound if the alarm part 34 is sounding the alarm sound, and the second crime prevention. The wireless communication unit 32 is caused to transmit a wireless signal including a control command instructing the sensor 2 to stop sounding the alarm sound (S8). As a result, the control unit 20 of the second security sensor 2 that has received the control command causes the alarm unit 24 to stop sounding the alarm sound.

  As described above, in the security system of the present embodiment, even if a resident approaches the window when the window is open, the second security sensor 2 does not detect it, so that the second security sensor 2 and the security receiver 3 erroneously warn. There is no sound. On the other hand, when a suspicious person approaches the window with the window open, the second security sensor 2 sounds an alarm sound to intimidate the suspicious person and also sounds an alarm sound from the security receiver 3 to the resident. I can inform you. Therefore, according to the crime prevention system of the present embodiment, it is possible to prevent a suspicious person from entering while suppressing a false alarm by a resident when a window is opened while at home.
