As shown in FIG. 2, the security device 2 includes an operation unit 20, a communication unit 21, a display unit 22, an input / output unit 23, a storage unit 24, and a control unit 25.

  The operation unit 20 is operated to set an operation mode of the security device 2 (a security set mode, a security release mode, etc., which will be described later). Further, the operation unit 20 has a function of reading user authentication information. When the authentication information is read and the user is collated, the operation input is permitted. The operation unit 20 may be configured by a touch panel or the like.

  The communication unit 21 has a function for communicating with the center device 3. The communication unit 21 is a communication interface for connecting the security device 2 and the center device 3. As described above, the security device 2 and the center device 3 are connected via the public line network or the Internet network as the network 4.

  The display unit 22 has a function of outputting an operation guide or the like to the user. The display unit 22 can be configured by a liquid crystal display, an indicator lamp, a speaker, and the like. The display unit 22 is installed near the operation unit 20 or is integrated with the operation unit 20. The display unit 22 provides an operation guide and menu display. The guidance of the operation and the like may be performed by voice notification from a speaker.

  The input / output unit 23 has a function as an interface to which peripheral devices such as the security sensor 8 are connected. The input / output unit 23 is a security sensor such as a magnet sensor that detects opening and closing of a door disposed at an appropriate place inside / outside of a building serving as an area to be monitored in a monitoring area, and an infrared sensor that detects a human body by infrared rays. It is connected to fire sensors such as smoke detectors and heat detectors, and emergency buttons operated by users. The input / output unit 23 is a communication interface that receives detection signals from various sensors. Each sensor is given a unique identification number, and the detection signal includes this identification number (ID number).

  The storage unit 24 stores operation log information. The operation log information is information in which information on detection of the security sensor 8, environment information accompanying communication, information on operation of the security device 2, and the like are recorded. The operation log information includes a plurality of types of information such as, for example, “reception electric field strength”, “wireless signal collision”, “operation start date”, “last battery replacement date”, “time required for security release”. included. Further, the storage unit 24 stores the set time, information of the set user, and information of the set operation mode as an operation mode history every time the operation mode is set. Further, the storage unit 24 stores sensor information (information in which sensor types and sensor installation positions are associated with each sensor ID number for each sensor) and an abnormality history. The abnormality history is a history of receiving a detection signal from the security sensor 8 when the security set mode and the inspection mode are set, and includes identification information of the security sensor 8 and information on a reception time.

  The control unit 25 has a function of performing various controls of the security device 2. In this case, the control unit 25 includes a mode setting unit 250, an abnormality detection unit 251, an abnormality notification unit 252, and a log information communication unit 253.

  The mode setting unit 250 sets an operation mode of the security device 2 by a user operation. As the operation mode of the security device 2, at least two of a security set mode and a security release mode can be set. The security set mode is a mode in which when a detection signal is input from the security sensor 8, it is determined that an abnormality has been detected in the monitored area, and an abnormality is notified to the center device 3. The security release mode refers to a mode in which, even when a detection signal is input from the security sensor 8, an abnormality is not detected in the monitored area and an abnormality is not reported. The detection signals from the fire sensor and the emergency button are constantly monitored, and an abnormality is reported in any of the security set mode and the security release mode. For example, the user operates the operation unit 20 to set the security set mode when leaving the monitoring area, and sets the security release mode by operating the operation unit 20 when entering the monitoring area.

  The abnormality detection unit 251 has a function of detecting an abnormality in the monitoring area. In this case, upon receiving the detection signal from the security sensor 8, the abnormality detection unit 251 determines whether there is an abnormality based on the current operation mode and the sensor information in the storage unit 24. The abnormality detection unit 251 determines that an abnormality is received when a detection signal is received from any of the various sensors when the security set mode is set, and determines whether the fire sensor or the emergency button is set when the security release mode is set. Therefore, when the detection signal is received, it is determined to be abnormal.

  When the abnormality detection unit 251 detects an abnormality, the abnormality notification unit 252 transmits an abnormality signal indicating the abnormality from the communication unit 21 to the center device 3. The abnormality signal includes identification information indicating the classification of the abnormality, the identification number of the security device 2, the ID number of the sensor that detected the abnormality, the type of the sensor, and information on its installation position. The classification of the abnormality is information indicating the classification that the abnormality detection unit 251 has determined to be abnormal. For example, in the classification of the abnormality, identification information corresponding to a detected factor such as detection of a moving object, abnormality of a wired communication, abnormality of a wireless communication, abnormality of a remaining battery level, detection of a fire, or the like is added in advance. Further, upon receiving a request signal (described later) from the center device 3, the log information transmitting unit transmits operation log information of a type corresponding to the request signal from the communication unit 21 to the center device 3.

  As shown in FIG. 3, the center device 3 includes a communication unit 30, a storage unit 31, and a control unit 32, and the control console 5 includes a communication unit 50, a display unit 51, and an operation unit 52. For example, the center device 3 is configured by a server device, and the control console 5 is configured by a personal computer. Here, the case where the center device 3 and the control console 5 are different devices will be described as an example, but the center device 3 and the control console 5 may be constituted by one device. In addition, the mobile terminal 6 includes a communication unit 60 and a touch panel 61. For example, the mobile terminal 6 is configured by a smartphone or the like.

  Here, each configuration of the center device 3 will be described in detail. The communication unit 30 has a function of communicating with the control console 5, the security device 2, and the mobile terminal 6. The center device 3 and the control console 5 are connected, for example, via a dedicated line. The center device 3 and the portable terminal 6 are connected via, for example, a mobile communication network.

  The storage unit 31 stores in advance the types of operation logs for estimating the cause of the abnormality corresponding to each abnormality classification. For example, the types of “reception electric field strength” and “radio signal collision” are stored as types of operation logs for estimating the cause of the abnormality in the classification of “radio communication abnormality”. In addition, types of “operation start date” and “last battery replacement date” are stored as types of operation logs for estimating the cause of the abnormality in the category of “battery remaining amount abnormality”. In addition, a type of “time required for security release” is stored as an operation log for estimating the cause of the abnormality in the classification of “installation position abnormality”. The type of the operation log for estimating the cause of the abnormality may be updated at any time as needed.

  The control unit 32 includes an abnormality classification determination unit 320, a display control unit 321, a request transmission unit 322, a cause estimation unit 323, a support information generation unit 324, a support information transmission control unit 325, and a status acquisition unit 326.

  Upon receiving the abnormal signal from the security device 2, the abnormal classification determining unit 320 determines the classification of the abnormality based on the identification information included in the abnormal signal. The display control unit 321 controls the display for dealing with the abnormality according to the classification of the abnormality determined by the abnormality classification determining unit 320. In this case, the display control unit 321 controls the display of the control unit 5 to display information necessary for dealing with the abnormality, such as the classification of the abnormality.

  The request transmission unit 322 has a function of transmitting a request signal requesting operation log information of a type corresponding to the abnormality classification determined by the abnormality classification determination unit 320 from the communication unit 30 to the security device 2. For example, when the abnormality classification determination unit 320 determines that the classification of the abnormality is “wireless communication abnormality”, a request signal requesting operation log information of “reception electric field strength” and “wireless signal collision” of the corresponding type is generated. It is transmitted to the security device 2. When the abnormality classification determining unit 320 determines that the classification of the abnormality is “battery remaining amount abnormality”, it requests operation log information of “operation start date” and “last battery replacement date” of the corresponding type. A request signal is transmitted to the security device 2. When the abnormality classification determination unit 320 determines that the classification of the abnormality is “installation position abnormality”, a request signal requesting operation log information of “time required for security release” of the corresponding type is sent to the security device 2. Sent to.

  Upon receiving the operation log information from the security device 2, the cause estimating unit 323 estimates the cause of the abnormality based on the operation log information before abnormality detection. Then, the support information generation unit 324 generates support information according to the abnormality cause estimated by the cause estimation unit 323.

  For example, when the type of abnormality is “wireless communication abnormality”, the cause estimating unit 323 becomes a target of wireless communication from the operation log information of “reception electric field strength” and “wireless signal collision” acquired from the security device 2. The received electric field strength of the wireless signal from the security sensor 8 in the most recent period through communication with the security sensor 8 was equal to or less than a predetermined value, or the frequency of signal collision (packet loss) of the wireless signal from the security sensor 8 Is detected, an abnormal cause of "deterioration of the communication environment" is estimated. Then, the support information generation unit 324 generates, as information of coping support for resolving the cause of the abnormality, support information of “suggesting environmental improvement using a repeater or the like” corresponding to the cause of the abnormality. On the other hand, if no decrease in the received electric field strength and no signal collision are found in the communication in the most recent period, the cause estimating unit 323 estimates the cause of the abnormality “failure of the device itself”, and the support information generating unit 324 determines Generates support information for "suggesting device replacement" according to the cause.

  When the type of the abnormality is “battery remaining amount abnormality (or battery near end)”, the cause estimating unit 323 stores the minimum level calculated from the expected battery life value for each device such as the security sensor 8 stored in advance. From the operation log information of the "operation start date" or "last battery replacement date" of the device obtained from the security device 2, if the battery usage period of the device to date is less than the minimum level value Then, the cause of the abnormality, that is, "failure of the device itself" is estimated. Then, the support information generation unit 324 generates support information of “suggesting device replacement”. On the other hand, if the battery usage period from the last battery replacement date (or operation start date) of the device to the present is equal to or longer than the minimum level value, the cause of the abnormality “battery abnormality” is estimated, and the support information generation unit 324 In response to the cause of the abnormality, support information is generated that suggests that only the battery be replaced.

  When the type of the abnormality is “installation position abnormality”, when the operation mode of the security device 2 is set to the security release (error recovery) mode after the notification of the intrusion abnormality, the cause estimation unit 323 sets the security device 2 From the operation log information of “time required for security release” obtained from the above, the margin of time required for security release in the past predetermined period (preset security release from detection of sensor at entrance / exit until it is determined that abnormality has occurred) A margin calculated from the average remaining time with respect to the allowable operation time) is obtained. If the margin of the time required for the security release in the past predetermined period is less than the threshold value, the cause of the abnormality of "the position where the user performs the security release operation is inappropriate" is estimated. The support information generation unit 324 generates support information indicating that “the planning of the installation position of the security device 2 in this monitoring area needs to be changed” according to the cause of the abnormality. On the other hand, if the margin of time required for security release in the past predetermined period is equal to or greater than the threshold, the cause estimating unit 323 estimates the cause of the abnormality “temporary operation error”, and the support information generation unit 324 determines According to the cause, support information is generated that states that "this abnormality is likely to be a temporary operation error and there is no need to change the planning".

  The support information transmission control unit 325 performs control for transmitting the support information to the mobile terminal 6 possessed by the care worker. When there is a carry-on item (battery or device for replacement) to be carried by the response person in order to deal with the abnormality, the support information transmission control unit 325 displays the information of the carry-over item and transmits the information. Control for confirming is performed. For example, the support information transmission control unit 325 controls the display of the carry-on item on the display unit of the control console 5 and waits for a confirmation input by the controller as to whether or not to transmit the carry-on item information to the mobile terminal 6. I do.

  The status acquisition unit 326 acquires status information indicating the status from the mobile terminal 6 as the current action state of the care worker. The status information is transmitted from the mobile terminal 6 to the control console 5 at a predetermined timing (for example, a timing of departure to the site, arrival at the site, handling, etc.). For example, the status acquisition unit 326 acquires status information from the control console 5. Note that the status acquisition unit 326 may directly acquire status information from the mobile terminal 6.

  The support information transmission control unit 325 determines whether or not the support information can be transmitted to the mobile terminal 6 according to the status of the response person. It is not preferable to transmit detailed information about the detected abnormality until the person arrives at the monitoring area where the person in charge takes action, in order to eliminate the assumption. For example, if the response person obtains information such as the detection position and cause at an early stage, if the response person assumes that the location, degree or accuracy of the abnormality is abnormal, the situation may cause an emergency threat such as an intruder. There is a risk that tension may be reduced. Therefore, the support information is transmitted if the status of the response person is after indicating "arrival at the site", and the support information is not transmitted if the status before arrival at the monitoring area such as "departure at the site".

  The operation of the security service support system 1 configured as described above will be described with reference to the sequence diagram of FIG.

  First, when the security device 2 detects an abnormality in the monitored area (S1), the security device 2 transmits an abnormality signal including identification information indicating a classification of the abnormality to the center device 3 (S2). When receiving the abnormality signal from the security device 2, the center device 3 executes control for displaying information necessary for handling on the control console 5 (S3), and the identification indicating the classification of the abnormality is sent from the center device 3 to the control console 5. An abnormal signal including information is transmitted (S4). When receiving the abnormal signal from the center device 3, the control console 5 displays information necessary for coping (S5). When the controller checks this display and inputs a response instruction (S6), the response instruction is transmitted from the control console 5 to the portable terminal 6 (S7) of the corresponding response operator. The operator checks the information received by the mobile terminal 6 and rushes to the monitoring area 2.

  The center device 3 determines the classification of the abnormality based on the abnormality signal received from the security device 2 (S8), and transmits to the security device 2 a request signal requesting operation log information of a type corresponding to the classification of the abnormality. (S9). When receiving the request signal, the security device 2 transmits operation log information of a type corresponding to the request signal to the center device 3 (S10).

  When receiving the operation log information from the security device 2, the center device 3 estimates the cause of the abnormality based on the operation log information before the abnormality is detected (S11), and generates support information corresponding to the estimated cause of the abnormality (S12). ). Then, when the generated support information includes the information of the portable item, the center device 3 transmits the information of the portable item to the control console 5 (S13), and the information of the portable item is displayed on the display unit of the control console 5. It is displayed (S14). If there is any belongings, the response person may have to pick up the belongings at an office or the like, which may delay arrival at the monitored area. For this reason, in the present embodiment, the controller checks this display and determines whether or not it is necessary to notify the handling staff of the information on the belongings and carry them. When the controller determines that it is necessary to carry the belongings with the responder, the controller 5 inputs the transmission of the belongings information from the control console 5 (S15). Then, the carrying item information is transmitted from the control console 5 to the portable terminal 6 (S16), and the attendant can check the carrying item information.

  To the control console 5, the status information of the counselor is transmitted from the mobile terminal 6 at a predetermined timing. When the center device 3 transmits a request signal for acquiring the status information of the response person to the control console 5 (S17), the status information is transmitted from the control console 5 to the center device 3 (S18). Then, if the status of the response person indicates that the person has arrived in the monitoring area, the support information is transmitted from the center device 3 to the portable terminal 6 (S19).

  According to the security service support system 1 of the present embodiment, when the security device 2 detects an abnormality, an abnormal signal is transmitted to the center device 3. The abnormal signal contains identification information indicating the classification of the abnormality. When the center device 3 receives the abnormal signal, the center device 3 can determine the classification of the abnormality from the abnormal signal. The center device 3 first controls the display for instructing a response person to deal with the abnormality according to the classification of the abnormality. Thereby, an appropriate instruction can be quickly sent to the response person. In addition, the type of the operation log for estimating the cause of the abnormality corresponding to each abnormality is stored in the center device 3 in advance. The center device 3 transmits a request signal to the security device 2 to request operation log information of a type corresponding to the classification of the abnormality. The security device 2 stores a plurality of types of operation log information, and upon receiving a request signal from the center device 3, transmits the type of operation log information corresponding to the request signal to the center device 3. As a result, only the operation log necessary for the classification of the abnormality (the operation log required by the center device 3 to estimate the cause of the abnormality) is transmitted. Communication load is reduced. In this manner, by transmitting the necessary operation log after transmitting the abnormal signal, it is possible to acquire information necessary for estimating the cause of the abnormality while ensuring promptness of abnormality detection. .

  In the present embodiment, the cause of the abnormality can be estimated from the operation log information before the abnormality is detected. For example, the cause of the “wireless communication abnormality” can be estimated from the information on the “reception electric field strength” and the “wireless signal collision”. Further, the cause of the abnormality of “battery remaining amount abnormality” can be estimated from the information of the “operation start date” and the “last battery replacement date”. Further, the cause of the abnormality of the “installation position abnormality” can be estimated from the “time required for security release” in the past predetermined period.

  Further, in the present embodiment, support information corresponding to the estimated cause of the abnormality is generated and transmitted to the portable terminal 6 of the care worker. If there is a portable item necessary to cope with the abnormality, control for displaying information on the portable item is performed. As a result, the support information is appropriately transmitted to the response staff, and if necessary, the information on the belongings is also transmitted. Based on such support information, the responder can take appropriate measures.

  Further, in the present embodiment, it is possible to determine whether or not to transmit the support information to the mobile terminal 6 according to the status of the response staff. For example, it is not preferable to transmit detailed information on the detected abnormality until the response person arrives at the site. Therefore, if the status of the response person is a status indicating "arrival at the site", the support information is transmitted, and if not, the support information is not transmitted. As a result, it is possible to transmit only necessary information to the operator according to the status of the operator.

  As described above, the embodiments of the present invention have been described by way of example. However, the scope of the present invention is not limited thereto, and can be changed and modified according to the purpose within the scope described in the claims. is there.

  For example, as shown in FIG. 5, the security device 2 may include an abnormality classification determination unit 254 that determines the classification of the abnormality detected by the abnormality detection unit 251. Also in this case, when the security device 2 detects an abnormality, first, an abnormality signal is transmitted to the center device 3. The abnormal signal contains identification information indicating the classification of the abnormality. When the center device 3 receives the abnormal signal, the center device 3 can determine the classification of the abnormality from the abnormal signal. The center apparatus 3 first performs display control for dealing with the abnormality according to the classification of the abnormality. Thus, an appropriate instruction according to the classification of the abnormality can be quickly sent to the response person. The security device 2 stores a plurality of types of operation log information, and transmits to the center device 3 the type of operation log information corresponding to the classification of the abnormality determined by the abnormality classification determining unit 254. As a result, only the operation log necessary for the classification of the abnormality (the operation log required by the center device 3 to estimate the cause of the abnormality) is transmitted. Communication load is reduced. In this manner, by transmitting the necessary operation log after transmitting the abnormal signal, it is possible to acquire information necessary for estimating the cause of the abnormality while ensuring promptness of abnormality detection. .

  As described above, the security service support system according to the present invention has an effect that it is possible to acquire information necessary for estimating the cause of an abnormality while ensuring promptness of abnormality detection. It is useful for security purposes and is useful.
