  Exemplary embodiments of a security device and method according to the present invention will be explained below in detail with reference to the accompanying drawings. The present invention is not limited to these embodiments.

  The present embodiment will be described with reference to the accompanying drawings. First, a configuration example of a security device to which the present invention is applied will be described. FIG. 1 is a block diagram showing a configuration of a security device according to the present embodiment.

  The security device 100 according to the present embodiment includes a sensor 101, a receiving unit 102, an operation panel unit 103, a control unit 104, a rewriting unit 105, a restart unit 106, a timer unit 107, program data A storage unit 108, a rewrite program / data storage unit 109, a security state storage unit 110, a security device information storage unit 111, and a communication unit 112 are provided. The security device 100 is connected to the monitoring center 200 via a network 300 such as the Internet.

  The sensor 101 detects an abnormality in the detection area. The sensor 101 includes, for example, an infrared sensor that detects a person based on a change in the amount of received infrared light, a shut-off sensor that detects a person by blocking infrared light, a sign sensor that detects a person by disturbance of electromagnetic waves, and a door using a magnet. These are various sensors for detecting an abnormality in a detection region such as a magnet sensor for detecting the opening / closing of the sensor. The receiving unit 102 receives detection information when the sensor 101 detects an abnormality.

  The operation panel unit 103 accepts display of information related to the security device 100 and input of information to the security device 100. The operation panel unit 103 receives an input of a security state by pressing a button displayed on the operation panel 102, for example.

  The control unit 104 controls each unit of the security device 100 such as the reception unit 102 and the operation panel unit 103. The control unit 104 can operate as the control unit 104 by reading the control program and setting data stored in the program / data storage unit 108 when the security device 100 is activated. Control. Here, the control program is a program (firmware) for controlling each part of the security device 100. The setting data is data used in the control program, that is, control data.

  The communication unit 112 transmits and receives various types of information to and from the monitoring center 200. The communication unit 112 receives information on rewriting, a control program, and setting data transmitted from the monitoring center 200, and stores the received control program and setting data in the rewriting program / data storage unit 109. In addition, the communication unit 112 transmits the result of the rewriting process such as the control program in the security device 100 to the monitoring center 200. Note that information on rewriting, a control program, and setting data may be transmitted from a server connected to the network 300 instead of the monitoring center 200. In addition, the communication unit 112 transmits alarm information to the monitoring center 200.

  The program / data storage unit 108 stores a control program and setting data that are currently controlling the security device 100. The program / data storage unit 108 is a readable / writable nonvolatile memory.

  The rewrite program / data storage unit 109 stores the control program and setting data transmitted from the monitoring center 200. The rewrite program / data storage unit 109 is a readable / writable nonvolatile memory, like the program / data storage unit 108. The rewrite program / data storage unit 109 may be the same storage medium as the program / data storage unit 108 or a different storage medium.

  The rewrite unit 105 stores the control program and setting data stored in the rewrite program / data storage unit 109 in the program / data storage unit 108 in accordance with the timing information transmitted from the monitoring center 200.

  Here, the timing information means that the control program and setting data are rewritten when the security state is the security release mode, the control program and setting data after rewriting are read and restarted, and the control program and setting are set. This is information combined with a designated date and time indicating the date and time when the data is rewritten and the control program and setting data after rewriting are read and restarted. Timing information includes “when security is released, December 26, 2007, 14:00”, when security is released, and setting date and time, “none, December 26, 2007, 14:00”. , Designation at the time of security release such as “when security is released, none”, and designation immediately after reception of “none, none” are possible.

  The restarting unit 106 restarts the security device 100 after the rewriting unit 105 rewrites the control program and setting data in order to operate the security device 100 with the control program and setting data stored in the program / data storage unit 108. Start. The restarting unit 106 turns off the power of the security device 100 and then reads and starts the control program and setting data stored in the program / data storage unit 108, thereby starting the control program and setting transmitted from the monitoring center 200. The security device 100 can be controlled by the data.

  The timer unit 107 measures the current date and time. In addition, the timer unit 107 measures the elapsed time from the start of timing.

  The security status storage unit 110 stores the current security status of the security device 100. Specifically, the security state that received the input from the operation panel unit 103 is stored. The security states that can be set by the security device 100 are roughly divided into a security mode and a security release mode. In the security mode, when the detection information transmitted when the sensor 101 detects an abnormality in the detection area is received, the alarm information notifying the abnormality in the security area is transmitted to the monitoring center 200 connected via the network 300. A security release mode is a mode in which alarm information is not transmitted to the monitoring center 200 even when the detection information is received.

  The security device information storage unit 111 stores information regarding the security device 100. Here, the information related to the security device 100 is a model ID indicating the model number of the security device 100 or the like.

  Next, the control program / setting data rewriting process by the security device 100 configured as described above will be described. FIG. 2 is a flowchart showing a control program / setting data rewriting process procedure performed by the communication unit 112 and the rewriting unit 105. The control program / setting data rewriting process is started when the rewriting start instruction and the corresponding model ID are transmitted from the monitoring center 200.

  First, the communication unit 112 of the security device 100 receives the rewrite start instruction and the rewrite target model ID transmitted from the monitoring center 200 (step S201). The rewriting unit 105 acquires the model ID from the security device information storage unit 111 (step S202). The rewrite unit 105 determines whether or not the received target model ID matches the model ID stored in the security device information storage unit 111 (step S203).

  If it is determined that the received target model ID matches the model ID stored in the security device information storage unit 111 (step S203: Yes), the communication unit 112 transmits a compliance signal to the monitoring center 200 (step S204). . The communication unit 112 receives the timing information, control program, and setting data transmitted by the monitoring center 200 in response to the conformance signal (step S205). The communication unit 112 stores the received control program and setting data in the rewrite program / data storage unit 109 (step S206).

  The communication unit 112 determines whether or not the control program and setting data have been normally received (step S207). If it is determined that the control program and setting data have been normally received (step S207: Yes), a control program / setting data rewriting process is executed (step S208). Details of the control program / setting data rewriting process will be described later.

  If it is determined that the control program and setting data have not been received normally (step S207: No), the communication unit 112 discards the control program and setting data stored in the rewrite program / data storage unit 109 (step S209). . The communication unit 112 transmits a reception data abnormality signal to the monitoring center 200 (step S210).

  If it is determined in step S203 that the received target model ID does not match the model ID stored in the security device information storage unit 111 (step S203: No), a non-conforming signal is transmitted to the monitoring center 200 (step S211). ).

  Next, the control program / setting data rewriting process will be described. FIG. 3 is a flowchart showing a control program / setting data rewriting process procedure performed by the rewriting unit 105.

  First, the rewrite unit 105 determines whether or not the timing release includes a security release designation (step S301). When it is determined that the security release designation is included in the timing information (step S301: Yes), the rewriting unit 105 determines whether the timing information includes the date designation (step S302). When it is determined that the date / time designation is included in the timing information (step S302: Yes), the rewriting unit 105 executes the rewriting process at the time designation / security release (step S303). Details of the processing will be described later. When it is determined that the date and time designation is not included in the timing information (step S302: No), the rewriting unit 105 executes a rewriting process at the time of security release (step S304). Details of the processing will be described later.

  If it is determined in step S301 that the timing release information does not include a security release designation (step S301: No), the rewrite unit 105 determines whether the timing information includes a date and time designation (step S305). ). When it is determined that the date / time designation is included in the timing information (step S305: Yes), the rewriting unit 105 executes a date / time designation rewriting process (step S306). Details of the processing will be described later. When it is determined that the date / time designation is not included in the timing information (step S305: No), the rewrite unit 105 executes a rewrite process (step S307). Details of the processing will be described later.

  Next, the rewriting process at the time designation and security release will be described. FIG. 4 is a flowchart showing a rewrite processing procedure at the time designation and security release performed by the rewrite unit 105.

  First, the rewrite unit 105 determines whether or not the current date is a specified date (step S401). If it is determined that the current date / time is not the specified date / time (step S401: No), the process returns to step S401, and this process is repeated until the current date / time becomes the specified date / time.

  If it is determined that the current date is the specified date (step S401: Yes), the rewrite unit 105 acquires the current security status from the security status storage unit 110 (step S402). The rewriting unit 105 determines whether or not the current security state is the security release mode (step S403). When it is determined that the current security state is the security release mode (step S403: Yes), a rewrite process is executed (step S404). Details of the processing will be described later. If it is determined that the current security state is not the security release mode (step S403: No), the rewriting unit 105 sets the designated date and time to one day (step S405), and returns to step S401. Note that the time to be added to the designated date and time is not limited to one day, and the time according to the actual situation of the security area where the security device 100 is installed is added.

  Next, the rewriting process at the time of security release will be described. FIG. 5 is a flowchart showing a rewrite processing procedure at the time of security release performed by the rewrite unit 105.

  First, the rewrite unit 105 acquires the current security state from the security state storage unit 110 (step S501). The rewrite unit 105 determines whether or not the current security state is the security release mode (step S502). If it is determined that the current security state is the security release mode (step S502: Yes), the process proceeds to step S509. When it is determined that the current security state is not the security release mode (step S502: No), that is, when it is determined that the current security state is the security mode, the rewrite unit 105 receives the current security from the security state storage unit 110. A state is acquired (step S503). The rewriting unit 105 determines whether or not the current security state is the security release mode (step S504). When it is determined that the current security state is the security release mode (step S504: Yes), the timer unit 107 starts a rewrite timer (step S505). Thereby, the timer unit 107 measures the elapsed time after the security release mode is set. If it is determined that the current security state is not the security release mode (step S504: No), the process returns to step S503, and this process is repeated until the current security state is set to the security release mode.

  The rewrite unit 105 acquires the current security state from the security state storage unit 110 (step S506). The rewrite unit 105 determines whether or not the current security state is the security release mode (step S507). When it is determined that the current security state is the security release mode (step S507: Yes), the rewrite unit 105 determines whether or not a predetermined time has elapsed since the start of the rewrite timer (step S508). If it is determined that the predetermined time has passed (step S508: Yes), the rewrite unit 105 executes a rewrite process (step S509). Details of the processing will be described later. If it is determined that the predetermined time has not elapsed (step S508: No), the process returns to step S506, and this process is repeated until the predetermined time elapses.

  In step S507, when it is determined that the current security state is not the security release mode (step S507: No), that is, when the security mode is set before the predetermined time elapses, the process returns to step S503. For example, when the housekeeper goes out again after returning forgetting something, the security state is often switched to the security mode immediately after setting the security status to the security cancellation mode. Rewrite processing is performed after the elapse. Thereby, the time which will be in an unguarded state can be shortened by performing rewriting processing.

  Next, the date and time designation rewriting process will be described. FIG. 6 is a flowchart illustrating a rewrite processing procedure for date designation performed by the rewrite unit 105.

  First, the rewrite unit 105 determines whether or not the current date and time is a specified date and time (step S601). If it is determined that the current date / time is not the designated date / time (step S601: No), the process returns to step S601 and this process is repeated until the current date / time becomes the designated date / time. If it is determined that the current date is the designated date (step S601: Yes), the rewrite unit 105 executes a rewrite process (step S602). Details of the processing will be described later.

  Next, the rewriting process will be described. FIG. 7 is a flowchart showing a rewrite processing procedure performed by the rewrite unit 105 and the restart unit 106.

  First, the rewrite unit 105 acquires a control program and setting data from the rewrite program / data storage unit 109 (step S701). The rewrite unit 105 stores the acquired control program and setting data in the program / data storage unit 108 (step S702).

  The restarting unit 106 restarts the security device 100 (step S703). Specifically, the restarting unit 106 turns off the security device 100, reads the control program and setting data stored in the program / data storage unit 108 into the control unit 104, and starts up. Thus, since the security device 100 is controlled by the control unit 104 into which the new control program and setting data transmitted from the monitoring center 100 are read, the control program and setting data that have been used to control the security device 100 so far Can control the security device 100 with different control programs and setting data.

  The rewriting unit 105 determines whether the restart has been successful (step S704). When it is determined that the restart is successful (step S704: Yes), the communication unit 112 transmits a rewrite success signal to the monitoring center 200 (step S705). If it is determined that the restart has not been successful (step S704: No), the communication unit 112 transmits a rewrite failure signal to the monitoring center 200 (step S706).

  As described above, the control program and setting data can be rewritten only by a rewriting instruction from the monitoring center 200, and the control program and setting data of the security device can be changed, so that the maintenance work load can be reduced.

  Also, by rewriting and restarting the control program and setting data according to the timing information, depending on the actual situation of security in the security area, for example, at a timing considering the security schedule of the security guard, the risk of suspicious person intrusion, etc. Since the security device 100 is in an unguarded state, it is possible to prevent deterioration of the security quality.

  Also, by not using the network 300 as a telephone line, it is possible to prevent the telephone line at the user's house from being used and the control program and setting data from being transmitted to the telephone at the user's house cannot be transmitted. .

  The security device 100 receives a control program and setting data from the monitoring center 200 and stores a rewrite program / data storage when receiving a rewrite stop signal from the monitoring center 200 until the received control program is rewritten. The rewriting of the control program and setting data stored in the unit 109 to the control program and setting data in the program / data storage unit 108 may be stopped.

  In the above-described embodiment, the example in which the control program and the setting data are rewritten at the same time has been described. However, even if one of the control program and the setting data is received from the monitoring center 200 and rewritten, The setting data may be separately received from the monitoring center 200 and the rewriting process may be performed at different timings. Note that the timing of each of the control program and the setting data is any one of “specified date and time when security is released”, “when security is released”, “specified date and time”, and “immediately after reception”.

  In addition, when rewriting and restarting the control program and setting data at different timings, in order to make the control program and the setting data consistent, the setting data and control program information suitable for each of the control program and the setting data are stored. Keep it and check if it matches when rewriting.

  Further, in order to manage the control program and setting data controlled for each security device 100, when the security device 100 is restarted by the restarting unit 106, the serial number of the control program and setting data is monitored. The monitoring program 200 may manage the control program currently operating for each security device 100, the serial number of the setting data, and the like.

  Further, in the security device 100, information other than information that needs to be immediately transmitted to the monitoring center 200 such as alarm information, for example, operation history information of the operation panel unit 103, ID of the sensor 101 that detected the abnormality, and detection time May be stored in a storage unit (not shown), and operation history information stored in the storage unit may be transmitted to the monitoring center 200 in response to a request from the monitoring center 200.

  Although the present invention has been described using the above-described embodiment, various modifications or improvements can be added to the above-described embodiment. Further, the configurations and functions described can be freely combined.
