[0001] DEVICE FOR OPENING DOOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing apparatus for opening and closing a locking device of a door under the control of a host.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing apparatus for detecting the temperature and humidity inside an enclosure and controlling the temperature and humidity of the enclosure when the sensed value exceeds a predetermined value.

The present invention relates to a door opening / closing device for detecting a vibration of a housing and reporting the alarm to the host when the detected vibration exceeds a predetermined value.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing apparatus for performing wired communication with a host,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door opening / closing apparatus connected to a host via an optimal path via an adjacent enclosure when not directly connected to a host wirelessly.

The present invention further relates to a door opening / closing apparatus for controlling a locking device of a door when a power failure occurs in a housing, and for supplying power to a communication unit to transmit failure information to a host .

The term " opening and closing device " means a device for controlling the opening and closing of a door.

Such an opening / closing device is intended to control the opening and closing of doors (doors) formed at the entrance of a specific object (building, vehicle, enclosure box).

In particular, the enclosure accommodates a control device for controlling a CCTV, a streetlight, a traffic signal controller (hereinafter, referred to as 'device'), and controls a single device connected through a control device or arranges devices into groups .

At this time, the enclosure is installed in a relatively low position so that the administrator can easily reach it.

This also applies to a general door opening / closing device other than the enclosure, so that any user with the intention of breaking or unauthorized intrusion of the device can intentionally approach and open the door or the door of the enclosure.

Therefore, the door of a specific device, including the enclosure, should be able to be opened and closed only by an authorized user.

For example, in the case of an enclosure, when an arbitrary user can easily control opening and closing of a door, the device connected to the enclosure can be operated arbitrarily, thereby reducing the efficiency of device operation.

Regarding this technique, Patent Document 10-1068897 discloses a storage management system via remote control.

The above-mentioned technology relates to a system for managing and controlling a storage box for storing important documents or objects such as offices, and more specifically, a system for controlling opening and closing of a storage box using a portable terminal such as a smart phone The portable terminal includes an NFC module so that the storage locker can recognize the portable terminal instead of a separate card key to open and close the storage box.

However, since the above-described technique controls opening / closing of the storage box only through the designated portable terminal, when the user using the designated portable terminal is away from the storage box by a certain distance or can not access the storage box, There are many ineffective problems in controlling the opening and closing of the door of a large number of doors.

In addition, the above-described technique can not only remotely control the opening and closing of the storage box, but also provide a condition for notifying the user of breakage of the storage box and information about forced opening and closing.

That is, there is a problem that the user can not know the failure of the storage box or the state abnormality until the user does not access the storage, and accordingly, the follow-up action can not be taken.

In this regard, a system for detecting the breakage or failure of the apparatus and notifying the failure has been developed. In this regard, a manhole monitoring system is disclosed in Korean Patent Publication No. 10-2009-0095966.

The above-described technique relates to a technique for real-time monitoring and management by constructing an unmanned monitoring system using a plurality of sensors in a manhole and transmitting manhole status information to a management server using a wired / wireless communication network.

However, the technique described above is effective in performing an unattended monitoring and notifying the management server when an abnormality occurs, which is advantageous in that subsequent processing can be performed. However, there is a problem that the maintenance function can not be performed when an abnormality occurs.

For example, when the temperature and the humidity of the manhole exceed a predetermined value, control means capable of controlling the temperature and the humidity of the manhole itself is further provided, so that dispatch of the mechanic to the manhole is not required, so unnecessary waste of manpower can be minimized There is an advantage.

In relation to this, the present applicant has filed a locker door opening / closing system in Application No. 10-2013-0100910 for the opening and closing of the door.

When the enclosure detects a failure and notifies the server of the failure, the server transmits a visit request signal to the mechanic terminal, and when the terminal receiving the visit request signal scans the recognition means provided in the enclosure, And the server transmits the location information of the enclosure and the location information of the terminal to the server. The server opens the enclosure door based on the location information of the enclosure and the terminal.

In addition, the above-described technique controls the temperature and humidity to be set to a predetermined temperature and humidity by providing a control unit when the temperature and the humidity are detected to exceed the set value. If the temperature and the humidity are not maintained and controlled despite the control, And outputs a failure signal to the server.

However, the above-described technique does not describe a configuration in which communication can be performed in place of a failure of communication in use.

In particular, a single management server must be able to control a range of enclosures. In the case of wireless communications, the radio frequency may be shorter than the maximum communicable distance due to external factors (e.g., building new) This leads to a problem that communication between the enclosure and the management server is not smoothly performed.

Therefore, it is possible to provide communication means that can replace the existing communication system even if a failure occurs in communication. Even if the wireless communication is not smooth, the topology can be constructed so as to communicate with other adjacent apparatuses, It is necessary to develop a technique capable of analyzing a control signal transmitted from a host while calculating a path.

Furthermore, when communication between the enclosure and the host is obstructed, it is possible to cope with the interruption of the power supply through the configuration in which the remaining battery or the remaining power of the power can be utilized, so that the door of the enclosure can be kept closed, The development of technology that is required

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door opening / closing device installed inside an enclosure and controlling a locking device of a housing based on control of a host. More particularly, the present invention relates to a door opening / closing apparatus that performs wire communication with a host, and communicates with a host wirelessly in case of a communication failure.

The enclosure of the present invention will be described with reference to Fig. 1 of the accompanying drawings.

1 shows an example in which a housing is installed in a door opening and closing apparatus according to the present invention.

In FIG. 1 of the accompanying drawings, the housing is shown as a housing 10 for streetlight control and a housing 10a for signal lamp control. However, in order to control a specific device such as a housing and a transformer control enclosure for CCTV control It can be any enclosure that is enclosed in a public place.

The enclosures 10 and 10a are also connected to the host 200. [ At this time, the host 200 transmits a control signal to the enclosure and maintains the enclosure at a remote place.

The enclosure 10 in the present invention may be in wired communication or wireless communication with the host 200, which will be described with reference to FIGS. 2 and 2A of the accompanying drawings.

FIG. 2 illustrates a plurality of enclosures in a door opening / closing apparatus according to the present invention communicating with a host through wires; FIG. 2A illustrates a plurality of enclosures communicating wirelessly with a host in a door opening and closing apparatus according to the present invention;

The enclosure 10, 10a, 10b according to FIG. 2 of the accompanying drawings is configured to communicate with a host by wire. That is, the host 200 and the door opening / closing apparatus 100 are configured to transmit and receive a predetermined signal such as a control signal through 1: 1 communication. Here, the wired communication is configured to communicate with the host 200 through the door opening / closing apparatus 100.

However, when the wired communication with the host 200 is interrupted, communication failure may occur. In this case, when it is determined that the wired communication failure has occurred, the door opening / closing apparatus 100 is configured to wirelessly communicate with the host (see FIG. .

That is, when the host 200 and the door switching apparatus 100 communicate with each other through wireless communication, the door switching apparatus 100 communicates with the door switching apparatuses 101 and 102 provided on the enclosures 10a and 10b adjacent to each other So as to perform 1: n communication between the host 200 and the door opening and closing apparatus 100. [

The door opening and closing device 102 that can not directly communicate with the host 200 is configured to communicate with the host 200 through the door opening / closing device 101 installed in the adjacent enclosure capable of communicating with the host 200 will be.

Hereinafter, the configuration of the door opening / closing apparatus 100 will be described with reference to Figs. 3 and 4 of the drawings.

FIG. 3 shows an example in which the door opening and closing device according to the present invention is installed inside the enclosure, and FIG. 4 shows a configuration of the door opening and closing device according to the present invention.

The door opening and closing apparatus 100 shown in FIG. 3 of the accompanying drawings is installed in the housing 10 and includes a communication unit 110, a control unit 120, a storage unit 130 and an RFID reader 140, (120) is provided with a locking device (11) installed on the enclosure (10) for controlling opening and closing of the door of the enclosure, a control device (12) for controlling the device connected to the enclosure, and a power source And a power supply unit 13 for supplying power.

The door opening and closing device 100 further includes a fan 150, a speaker 160 and a sensor 170. The fan 150, the speaker 160 and the sensor 170 are connected to the controller 120 And may be installed inside the enclosure outside the door opening and closing apparatus 100.

The communication unit 110 performs wired communication or wireless communication with the host 200. The communication unit 110 includes a wired communication module and a wireless communication module.

At this time, a wired connector is connected from the outside for wired communication through the wired communication module, and the wired connector is preferably configured by an RJ-45 connector.

The wireless communication module enables wireless communication with the host 200 according to the control of the control unit when a failure occurs in the wired communication between the host 200 and the door opening and closing apparatus 100.

At this time, the wireless communication is made up of a wireless sensor network built through Zigbee.

Wireless Sensor Network (WSN) is a wireless network that can measure and detect various status and environmental information such as temperature, humidity, illuminance, and pressure remotely without constructing a separate wired network.

In order to configure the sensor network wirelessly, many wireless sensor nodes form a single wireless network distributed in a certain area, and are connected to a separate server through wired / wireless networks such as PCS, WLAN, xDSL, and Kornet.

Depending on the design conditions, by constructing the wireless sensor network as described above, it is possible to monitor more abnormalities in cooperation with the sensors configured in the vicinity, and to communicate with other wireless sensor networks.

In addition, the information monitored through the sensor can be configured to be transmitted to the host 200 via the wired or wireless network described above.

For example, the present invention can be constructed in connection with the safety management system for camping in Korean Patent Registration No. 10-1332414 filed and filed by the present applicant.

The camping safety management system includes a terminal and a sensor, detects the state of the air, and generates a warning signal based on the detected air state data and the set data, thereby allowing the user to take subsequent actions .

In addition, campers (campers) can be efficiently managed by detecting campus departure and warning.

That is, the door opening / closing apparatus 100 according to the present invention is not necessarily installed inside the enclosure but may be installed in a door at a specific place such as a camping site, The wireless sensor network may be configured to be associated with the wireless sensor network.

However, in the case of the enclosure, it is installed irregularly in a wide range according to the geographical condition or the environmental condition. In order to manage the enclosure installed in such a wide range in a single host, a plurality of sensor nodes having a short- Hop network is needed.

The network supporting multi-hop can be configured as a topology such as a chain type structure, a mesh type structure, a star type structure, etc. However, in the present invention, it is possible to freely transmit the optimal route in the transmission range without depending on the hierarchical structure of the ZigBee network Employ a mesh topology structure to perform.

Such a topology structure of the present invention will be described with reference to FIG. 5 of the accompanying drawings.

5 is a view showing an example of a topology constructed when the door opening / closing device according to the present invention is wirelessly communicated with a door opening / closing device and a host installed in another adjacent enclosure.

The door opening and closing devices 101, 102, 103, and 100n according to FIG. 5 of the accompanying drawings are constructed in the form of a mesh type topology with the host 200.

That is, each of the door opening / closing devices 101, 102, 103, and 100n is configured to communicate with the host 200 in a mutually connected manner.

The control unit 120 controls the locking device of the enclosure 10 based on the control signal of the host 200 received through the communication unit 110 and monitors the failure state of the enclosure 10, An opening / closing control module, an enclosure control module, a sensing control module, and a failure detection module.

The opening / closing control module controls the opening / closing of the enclosure locking device based on the control signal of the host 200.

The sensing control module controls the sensing operation of the sensor installed in the housing. For example, an external power source is applied to the sensor so that the sensor can operate.

At this time, the sensor installed on the housing may be composed of a constant temperature and humidity sensor for sensing the temperature and humidity inside the housing or a vibration sensor for sensing the vibration applied to the housing.

The enclosure control module controls the fan or the speaker installed inside the enclosure based on the detection value of the sensor installed inside the enclosure.

In addition, when the sensor 170 is configured as a constant-temperature and constant-humidity sensor, if the temperature and humidity inside the enclosure are detected to exceed a predetermined value, the fan 150 connected to the control unit 120 is driven to adjust the temperature and humidity inside the enclosure Adjust it.

(E.g., SMPS, etc.) that can control the current applied to the fan 150 according to the design conditions, and can control the driving speed of the fan 150 based on the sensed values of temperature and humidity have.

For example, if the temperature and humidity inside the housing exceed the set reference value and the temperature and humidity inside the housing are detected to exceed the set reference value even though the fan 150 is driven, the fan 150 The driving speed of the fan 150 can be increased.

Accordingly, even if the temperature and humidity are detected to exceed the reference value, the temperature and humidity inside the enclosure can be adjusted without moving the mechanic.

However, when the temperature and the humidity inside the enclosure are not controlled and the temperature and humidity are continuously detected by the constant temperature and humidity sensor by the above-described operation, the sensor information (sensed value) is transmitted to the host 200 via the wired / And the like.

In addition, when the sensor 170 is configured as a vibration sensor, the alarm is outputted through the speaker connected to the controller 120 when a vibration exceeding a predetermined value is detected in the housing.

At this time, if vibration is detected to output an alarm, the control unit 120 may be configured to notify the host 200 of sensor information (sensed value) for vibration detection through a wired / wireless network.

The failure detection module detects the failure of the lock device 11, the control device 12, and the power supply device 13, which are installed in the housing and control the street lamp, signal lamp, CCTV etc. connected to the housing.

Also, the controller 120 may analyze a signal received through the communication unit 110.

For this, the controller 120 may further include a signal analysis module (not shown).

For example, when the door switching apparatus 100 receives the control signal transmitted from the host 200, the control unit 120 analyzes whether or not the control signal is received.

As a result of the analysis, if it is not the object of reception, the control unit 120 resends the control signal through the communication unit 110.

At this time, the control signal transmitted again by the door opening / closing apparatus 100 can be received by another door opening / closing apparatus 100n which can communicate normally. However, since the present invention is configured in a mesh topology, There is a problem to be done.

The controller 120 of the door opening / closing apparatus 100 according to the present invention can discard the control signal when it is analyzed that the control signal is overlapped with the control signal that was previously transmitted again as a result of analysis of the received control signal .

Accordingly, it is possible to continuously transmit duplicated signals, and to prevent malfunctions of the apparatuses that are generated due to reception of the signals.

In addition, the lock device 11 of the present invention can employ EM lock, which may cause a power failure due to connection disconnection with a host, external impact, or corrosion of an internal structure.

This power failure can be detected through the failure detection module. This is because the power line applied to the control unit 120 is separately provided from the power applied to the configuration of the door opening / closing apparatus 100, It is possible to detect that a power failure has occurred when there is no response to information transmission / reception for a certain period of time in the communication unit 110, the storage unit 130, and the RFID reader 140 as a constituent.

Here, the predetermined time may be five minutes. However, it is not necessarily limited to 5 minutes, and it may be set to 5 minutes or less according to design conditions.

In this case, the electric power applied to the EM lock is also cut off due to the power shutoff inside the enclosure, which may open the door, thereby deteriorating the security of the enclosure.

Further, the power applied for communication is also blocked, so that a failure can not be notified to the host.

In order to solve the above-described problems, the door opening / closing apparatus according to the present invention may further include an auxiliary battery (not shown in the figure).

At this time, the auxiliary battery can be configured to charge the power while the power failure does not occur, which can be designed to charge the power through the constant power supplied from the outside.

Thus, the auxiliary battery can be designed so as to smoothly perform the charging (a) to detect the charged amount and (b) to stop charging when the charged amount is detected to be full. To this end, the auxiliary battery may further include a charge amount detection module and a charge control module.

Such an auxiliary battery may be energized to keep the enclosure door closed when power failure is detected in the fault detection module.

In addition, since failure information on a failure must be transmitted to the host 200, power can be supplied to the communication unit 110 from the auxiliary battery.

At this time, transmitting the failure information to the host 200 can be connected to the host through wireless communication.

In addition, depending on other design conditions, the door opening / closing apparatus 100 may be configured to release the failure information when power is applied to the communication unit 110.

That is, since the enclosure including the door opening / closing device that detects the power failure is connected to the mesh network through the wireless communication with the adjacent enclosure, it is configured such that the fault information is transmitted to the host 200 via the adjacent enclosure by releasing the fault information You may.

According to another design condition, the communication unit 110 may not perform its original function even if the door opening / closing apparatus 100 is turned off and electric power is applied to the communication unit 110 through the auxiliary battery.

In this case, the door opening / closing apparatus 100 may further include a separate second wireless communication module (not shown in the drawing). In this case, can do.

At this time, the second wireless communication module is not directly connected to the host 200 wirelessly, but can perform a function of emitting failure information.

The reason for this is that the second wireless communication module is a unique configuration and does not operate unless a power failure occurs, and when a failure such as a power failure is detected by the failure detection module and / or when the communication unit 110 performs its original function If not, it is designed as a means to release fault information.

Therefore, even if the function of the communication unit 110 is not re-performed by the auxiliary power supply due to the power failure, there is an advantage that the failure information can be transmitted to the host 200 via another adjacent enclosure.

According to another configuration of the second wireless communication module, even if the communication unit 110 performs the original function by the auxiliary power of the auxiliary battery in accordance with the design condition, When the auxiliary power is supplied, it is also possible to configure to emit the failure information irrespective of the communication unit 110.

In this case, since the host can receive the redundant failure information in the communication unit and the second wireless communication module, the host can be configured to discriminate the redundant failure information.

The storage unit 130 stores location information, failure information, and topology information of the enclosure 10, and includes a location information storage module, a failure information storage module, and a topology information storage module.

First, the location information storage module stores location information of the enclosure 10, and the failure information storage module stores failure information according to the failure state of the enclosure 10.

The topology information storage module also stores communication path information with which the host 200 and the door opening / closing apparatus 100 can communicate.

That is, the topology information indicates construction information of a communication network in which a plurality of the door opening / closing apparatuses 100 and the host 200 are constructed, which will be described with reference to FIG. 6 of the accompanying drawings.

6 is a diagram for explaining a transmission process when a host and each door opening and closing device perform wireless communication in the door opening and closing apparatus according to the present invention.

Referring to FIG. 6 of the accompanying drawings, a host and a plurality of door opening / closing devices T1 to T6 are displayed.

That is, each of the door opening and closing apparatuses T1 to T6 is configured to store the topology information as shown in FIG. 6 of the accompanying drawings.

At this time, Target 1 (hereinafter, referred to as 'T1' and others as described above) to T3 can perform direct wireless communication with a host, while T4 to T6 are locations where wireless communication with a host is impossible Lt; / RTI >

At this time, the Target is a term for describing the topology information according to the present invention, and T1 to T6 described below may have the meaning of a terminal (a door opening / closing device passing through) according to circumstances.

For example, in case of T4 (Target 4), since it can not directly communicate with the host, it must pass through another target (terminal), and the path exists in various cases.

That is, T4 may transmit information to a host through T3-T1, transmit information through T3-T2, or communicate with a host via only T3. In this case, T4 (Target 4) can transmit failure information by selecting an optimal path to be connected to the host via only T3 (Terminal 3).

Accordingly, the door opening / closing apparatus 100 can transmit the failure information according to the failure state of the enclosure and the position information of the enclosure to the host through the optimal path.

As another example, when a host sends a control signal to T4 (Target 4), it can not perform direct wireless communication, so it must send a control signal to T4 via another target (Terminal). At this time, (Host) can transmit the address including the address in the control signal.

For example, if it is determined that the route is the optimal route via T3 based on the topology information stored in the host, the host may be configured to transmit a control signal including an address such as "T3_T4_control signal ".

Accordingly, T1, T2, and T3 that receive the control signal transmitted from the host for the first time can analyze the corresponding control signal as described above, and can resend the control signal when the control object is not the person himself / herself.

If a control signal is received at T4 through this process, T4 may analyze the control signal to determine that the control target is the control target, and perform a control operation according to the control signal.

At this time, the T3 receiving the control signal from the host can receive the control signal again from T1 and T2 after resending the corresponding control signal.

In this case, retransmission of the same control signal is performed to perform an unnecessary operation, and T4, which has already performed the control operation, may receive a re-transmitted control signal to cause a malfunction. Therefore, It is possible to discard the control signal which overlaps with the control signal.

The door opening / closing apparatus 100 further includes an RFID reader 140. [

The RFID reader 140 recognizes the RFID tag provided on the mechanic terminal (not shown).

The host 200 receiving the failure information and the location information requests the mechanic terminal to visit the corresponding enclosure and accordingly the RFID reader 140 installed in the repairer terminal accessing the enclosure It recognizes.

For example, when the mechanic terminal requests opening / closing of the door through the RFID tag located in the recognition range of the RFID reader 140, the host 200 opens the locking device of the door with the door opening / closing device 100 And sends out a control signal.

At this time, the control signal includes information of the accessed mechanic terminal (information corresponding to the RFID tag), and the controller 120 compares the information of the recognized RFID tag with the information of the mechanic terminal included in the control signal, So that the locking device of the housing 10 is opened.

Accordingly, it is possible to prevent the unauthorized terminal from opening and closing the enclosure door from the host 200. [

The door opening / closing apparatus according to the present invention configured as described above detects the temperature and humidity in the housing and adjusts the driving speed of the fan according to the sensed temperature and the degree of humidity to prevent the housing from being damaged due to temperature and humidity And unnecessary dispatch can be minimized, so that waste of manpower can be prevented.

In addition, since the present invention controls wireless communication in the event of a wire communication failure with a host, it is possible to quickly process subsequent actions due to a communication failure.

Further, in the case of performing wireless communication, it is possible to establish a wider range of communication range because it is configured to communicate with the host via another adjacent enclosure.

Also, since the present invention can calculate the optimal distance to the host based on the stored topology information, the time required for communication can be minimized.

Further, since the present invention can be installed not only in an enclosure but also in a doorway, it can provide a wide range of options that can be applied and can be applied to a wireless sensor network constructed through peripheral sensors, So that various states can be monitored.

1 to 6 are merely the main points of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 1 to 6 It is self-evident.
