Description

  The present invention relates to a security system, and more particularly to a security system that reports security information using a radio signal.

  In the conventional security system, the security state of the security area is switched as follows. That is, when the security state of the security area is switched, the security guard patrols each security area, and the security staff directly switches the security terminal for each security area, thereby switching the security status of the security area. In other words, the security state of each security area is switched by operating a security terminal installed in a security room in each security area.

  As described above, in the conventional security system, the security state (mechanical security, patrol security, and security release) of each security area is switched by directly operating the operation unit of the security terminal. Therefore, the security guard had to carry data stored in the operation key, card, memory card, USB memory, and the like.

  Various prior art documents related to the present invention are known.

  For example, Japanese Patent Application Laid-Open No. 2007-312066 (Patent Document 1) discloses a security system that improves the reliability of a reporting operation in a security terminal equipped with a PHS (Personal Handyphone System) module. The security system disclosed in Patent Document 1 includes a plurality of security terminals. Each security terminal includes a PHS module that transmits and receives data in accordance with a PIAFS (Personal Handyphone System Internet Access Forum Standard) communication control procedure. Each security terminal exchanges data with the base station via the PHS module.

  Japanese Patent Laying-Open No. 2009-093520 (Patent Document 2) discloses a security system that reduces the burden on the user, reduces false alarms, and reduces the security burden. The security system disclosed in Patent Literature 2 sets the monitoring area to the security state when the user goes out of the monitoring area, and releases the security of the monitoring area when the user returns to the monitoring area. The security system includes a security device and an information recording medium that can be carried by a user. The information recording medium includes an RFID (Radio Frequency Identification) tag. The security device is arranged inside the monitoring area. In the monitoring area, a controller, a sensor, and an RFID reader connected to the security device are arranged. The RFID tag periodically transmits a tag ID to the RFID reader of the security device. The RFID reader periodically receives the tag ID and confirms that it is a registered RFID tag by authenticating with the tag ID registered in the security device. The security device mainly includes a sensor, an RFID reader, a controller, an input / output control unit, a control unit, and a communication control unit. The control unit controls the entire security device, and mainly includes a security mode setting unit, a security mode storage unit, a tag detection unit, a notification unit, and a notification unit. If the tag ID transmitted from the RFID tag can be received, the tag detection unit determines that the RFID tag is present within the RFID tag detection area based on the communication state. When the security mode setting unit detects a person in the monitoring area by the sensor when the security mode storage unit stores the security status, the RFID tag exists in the RFID tag detection area based on the detection result of the tag detection unit. If it is determined to be present, and it is determined that it exists, the stored contents of the security mode storage unit are changed to the security release state, thereby setting the security release state.

  The second and third PHS master units 22 and 32 also have the same configuration as the first PHS master unit 12.

  Next, features of the present invention will be described.

  A feature of the present invention is that in the security areas 1 to 3, the PHS handset 4 carried by the security guard is used in the security area to switch between the “mechanical security” of the security terminals 11, 21, and 31 and the “patrol security” by the security guard. 1-3, the entrance of the security system is judged based on the electric field strength at the time of position registration in the PHS master units 12, 22, and 32 and the ID of the PHS slave unit 4, and the security state is automatically switched, and the information (signal) The security center 7 is automatically notified, and the security center 7 is notified of the security release to the PHS handset 4 of the security guard.

  In FIG. 1, in the first security area 1, each first sensor 13 is connected to the first security terminal 11. The first security terminal 11 includes a PHS module 45 and transmits / receives security information to / from the security center 7 via the first PHS master unit 12, the PBX 5, and the public network 6.

  Also in the second and third security areas 2 and 3, the second and third security terminals 21 and 31 connected to the second and third sensors 23 and 33, the second and third PHS base units 22. 32, security information is transmitted and received. In the security system information storage unit 53 of the PHS master units 12, 22, and 32 in each of the security areas 1 to 3, the ID and PHS child of the PHS slave device 4 carried by the guard in advance in the case of patrol guard by the guard. The threshold value of the electric field strength of the machine 4 is stored.

  That is, the security system information storage unit 53 functions as an ID storage unit that stores the ID of the PHS slave unit 4 as a registration ID and a threshold storage unit that stores a threshold value of the electric field strength of the PHS slave unit 4.

  With reference to FIG. 4, an operation when a security guard enters the security areas 1 to 3 for patrol will be described.

  The PHS slave unit 4 is connected to the nearest first PHS master unit 12 by a known PHS radio control procedure. The PHS slave unit 4 sends a location registration request to the first PHS master unit 12. When receiving the location registration request, the first PHS master device 12 sends an authentication request to the PHS slave device 4. When the validity of the ID or the like is confirmed for the authentication response from the PHS slave unit 4, the first PHS master unit 12 sends a location registration acceptance signal to the PHS slave unit 4 to complete the location registration. .

  The security guard carries the PHS slave unit 4 having the same ID as the ID (registration ID) of the PHS slave unit 4 stored and registered in the security system information storage unit 53 of the first PHS master unit 12 in advance. In the position registration and authentication performed by the PHS slave unit 4 when a member enters the security areas 1 to 3, the CPU 51 of the first PHS master unit 12 compares and determines the ID of the PHS slave unit 4 and the threshold value of the electric field strength. Judge whether or not you are a security guard and switch the security status.

  That is, the CPU 51 compares the field strength comparison means for comparing the threshold value with the measured value, the ID comparison means for comparing the registered ID stored in the security system information storage unit 53 with the ID of the PHS slave unit 4, and the field strength comparison. Based on the comparison result of the means and the comparison result of the ID comparison means, it functions as a confirmation means for confirming the validity of the PHS slave unit 4.

  In this way, the security system of the present invention is adapted to the ID authentication of the PHS slave unit 4 and the electric field of the PHS master units 12, 22, 32 when the position of the PHS slave unit 4 is registered when entering the security areas 1 to 3. The intensity threshold is compared and detected. Therefore, it is not necessary to install the security terminals 11, 21, 31 in a place (security room) different from the security areas 1 to 3. Moreover, it is not necessary for the security guard to directly operate the security terminals 11, 21 and 31 to set the security release for the entrance. Furthermore, it is not necessary for the security guard to have (carry) a KEY, a memory card, a USB memory, or the like as means for releasing the security. The security system of the present invention can perform patrol, maintenance, etc. easily by using the PHS handset 4 used as a normal communication means.

  Next, the 1st operation | movement (1st Example) of the security system of this invention is demonstrated.

  First, in FIG. 1, an operation when a security guard carrying the PHS handset 4 approaches or enters the first security area 1 to which the first security terminal 11 belongs for security purposes. explain.

  In this case, the PHS module 54 (measuring means) of the first PHS master unit 12 is wirelessly connected to the PHS slave unit 4 in accordance with the communication control procedure in the self-supporting mode between the PHS slave unit 4 and the first PHS master unit 12. Measure the electric field strength of and output the measured value. Subsequently, the CPU 51 (electric field strength comparison means) of the first PHS master device 12 stores the measured value and the threshold value of the electric field strength of the PHS slave device 4 previously set in the first PHS master device 12 (security system information storage). (Threshold value stored in the unit 53). When the electric field strength is satisfied (that is, the measured value is equal to or greater than the threshold value), the CPU 51 (ID comparison unit) of the first PHS master unit 12 then uses the ID and registration ID ( The registration ID stored in the security system information storage unit 53 is compared. Then, the CPU 51 (confirmation means) of the first PHS master unit 12 confirms whether or not the first PHS master unit 12 can be used in the security system to which the first PHS master unit 12 belongs. That is, the CPU 51 (confirmation means) of the first PHS master unit 12 confirms the validity of the PHS slave unit 4 based on the comparison result of the electric field strength comparison means and the comparison result of the ID comparison means.

  The comparison of electric field strength and the authentication of ID are performed by the CPU 51 of the PHS parent device 50 (first PHS parent device 12) in FIG. That is, as described above, in the security system information storage unit 53, the ID (registration ID) of the PHS cordless handset 4 carried by the security guard in advance for security and the threshold value of the electric field strength in the first security area 1 are stored. Is registered and saved. First, the CPU 51 compares the threshold value with the data of the electric field intensity actually measured by the PHS module 54 (measurement means). Subsequently, the CPU 51 authenticates the ID of the PHS slave unit 4 and the registration ID in the call / PIAFS communication control procedure, and confirms the validity of the PHS slave unit 4.

  It is assumed that it is confirmed that the electric field strength and ID of the PHS slave unit 4 are satisfied. In other words, the CPU 51 (confirmation means) of the first PHS base unit 12 indicates that the comparison result of the electric field strength comparison means indicates that the measured value is equal to or greater than the threshold value, and the ID comparison means indicates that the registered ID and the PHS child It is assumed that the PHS slave device 4 is valid because it matches the ID of the device 4. In this case, the CPU 51 of the first PHS master unit 12 transmits, to the first security terminal 11, patrol guard request data for requesting patrol guard by the guard through the PHS module 54. That is, the CPU 51 of the first PHS master unit 12 cooperates with the PHS module 54 to request a patrol guard requesting patrol guard by the guard when the confirmation means determines that the PHS slave unit 4 is valid. It functions as a transmission means for transmitting data to the first security terminal 11.

  In response to this patrol guard request data, the first guard terminal 11 (CPU 41, PHS module 45) sends the first guard to the guard center 7 via the first PHS master unit 12, the PBX 5, and the public network 6. The first security terminal 11 (security state) in area 1 is notified that a release setting request has been made from “mechanical security” to “security release”. In other words, the CPU 41 of the first security terminal 11 cooperates with the PHS module 45 and responds to the patrol security request data to the security center 7 via the first PHS master unit 12 to send the machine security. It functions as a notification means for notifying a cancellation setting request signal for requesting cancellation.

  The security center 7 determines whether or not the cancel setting request signal matches the pre-registered tour time. That is, the security center 7 includes a determination unit that determines whether or not the cancellation setting request signal coincides with a tour time registered in advance. If this determination means confirms, the security center 7 sends to the first security terminal 11 via the first PHS main unit 12 the release permission information that permits the release of the machine security. . In other words, the security center 7 sends, to the first security terminal 11 via the first PHS main unit 12, the release permission information that permits the release of the machine security when the determination means confirms the release. Delivery means are provided.

  Based on this release permission information, the CPU 41 of the first security terminal 11 uses the detection information (security data storage unit 43) from the first sensor 13 connected to the first security terminal 11 as “machine”. Set from “Security” to “Course Security”. In other words, the CPU 41 of the first security terminal 11 cooperates with the security data storage unit 43 to change the security status of the first security area 1 from “mechanical security” to “tour” based on the release permission information. It works as a security state setting means to be set to “security”.

  At the same time, when the first PHS master unit 12 receives the release permission information, the first PHS master unit 12 transmits an incoming signal to the PHS slave unit 4 to notify the first security terminal 11 of “mechanical security release”. This incoming signal also includes machine security release information. That is, the CPU 51 of the first PHS master unit 12 cooperates with the PHS module 54 to transmit an incoming signal including machine security release information to the PHS slave unit 4 when the release permission information is received. work.

  After the machine security is released, the security information detected by the first sensor 13 is notified and stored in the first security terminal 11 and the security center 7. However, it is not an alarm because it has already been notified that the guard is a patrol by a guard.

  The same operation as described above is also performed when a security guard carrying the PHS handset 4 approaches or enters the second and third security areas 2 and 3.

  Next, an operation when a security guard carrying the PHS cordless handset 4 tries to leave the first security area 1 to which the first security terminal 11 belongs will be described.

  In this case, the electric field strength of the PHS slave unit 4 is weakened. In other words, the comparison result of the electric field strength comparison means indicates that the measured value is lower than the threshold value. In this case, the CPU 51 of the first PHS base unit 12 instructs the first security terminal 11 to restart the machine security by the first security terminal 11 via the PHS module 54. Send. That is, when the CPU 51 of the first PHS master unit 12 cooperates with the PHS module 54 and the comparison result of the electric field strength comparison means indicates that the measured value is lower than the threshold value, the first guard It functions as transmission means for transmitting security restart instruction data for instructing restart of machine security by the terminal 11 to the first security terminal 11.

  In response to the security resumption instruction data, the first security terminal 11 (CPU 41, PHS module 45) sends the first security to the security center 7 via the first PHS master unit 12, the PBX 5, and the public network 6. The first security terminal 11 (security status) in area 1 is notified that a restart setting request has been made from “security release” to “machine security”. In other words, the CPU 41 of the first security terminal 11 cooperates with the PHS module 45 and responds to the security resumption instruction data to the security center 7 via the first PHS master unit 12 to receive the machine security. It functions as a notification means for notifying a restart setting request signal for requesting restart.

  In response to this restart setting request signal, the security center 7 sends resumption permission information for permitting resumption of machine security to the first security terminal 11 via the first PHS master unit 12. That is, in response to the restart setting request signal, the security center 7 sends, to the first security terminal 11 via the first PHS master unit 12, resumption permission information that permits resumption of machine security. including.

  Based on this resumption permission information, the CPU 41 of the first security terminal 11 uses the detection information (security data storage unit 43) from the first sensor 13 connected to the first security terminal 11 as Set from "Security" to "Machine Security". In other words, the CPU 41 of the first security terminal 11 cooperates with the security data storage unit 43 to change the security status of the first security area 1 from “travel security” to “machine” based on the restart permission information. It works as a security state setting means to be set to “security”.

  At the same time, when the first PHS master unit 12 receives the resume permission information, the first PHS master unit 12 transmits an incoming signal to the PHS slave unit 4 to notify the first guard terminal 11 of “Resume machine guard”. This incoming call signal also includes machine security restart information. That is, the CPU 51 of the first PHS master unit 12 cooperates with the PHS module 54 to transmit an incoming signal including machine guard resume information to the PHS slave unit 4 when the resuming permission information is received. work.

  The same operation as described above is also performed when the security guard carrying the PHS handset 4 is about to leave the second and third security areas 2 and 3.

  The first embodiment of the present invention described above has the following effects.

  The first effect is that the setting from “mechanical security” to “patrol reconciliation” is performed by measuring and authenticating the electric field strength and ID of the PHS cordless handset 4 carried by the security guard using the PHS master unit, Since it is detected that a security guard has entered or approached, it is possible to set the “patrol guard” without directly operating the security terminal.

  The second effect is that by installing a security terminal in the security area, it is not necessary to install a special place such as a security room, and unauthorized operation of the security terminal can be prevented.

  Next, the second operation (second embodiment) of the security system of the present invention will be described.

  First, in FIG. 1, an operation when a security guard carrying the PHS handset 4 approaches or enters the first security area 1 to which the first security terminal 11 belongs for security purposes. explain.

  In the security center 7, a release special number is set in advance as a machine security release request.

  Assume that a security guard carrying the PHS handset 4 enters the first security area 1 for patrol. In this case, the release special number is transmitted from the PHS slave unit 4. That is, the PHS handset 4 has a transmission means for transmitting the release special number when entering the first security area 1.

  When receiving the release special number, the security center 7 sends, as response data to the incoming call, the first security terminal 11 via the first PHS master unit 12, the release instruction data for instructing the release of the machine security. . That is, when receiving the release special number, the security center 7 sends the release instruction data for instructing the release of the machine security as response data to the first security terminal 11 via the first PHS main unit 12. Means.

  The first security terminal 11 releases the machine security by the first sensor 13 based on the release instruction data. In other words, the CPU 41 of the first security terminal 11 cooperates with the security data storage unit 43 to change the security status of the first security area 1 from “mechanical security” to “ It works as a security status change means to change to "patient security".
