Description

  The present invention relates to a security system, and more particularly, to a security system and a security device that can access a security device from a mobile terminal and change the security state.

  In recent years, a security system for monitoring an abnormality occurring in a house or the like at a remote monitoring center has become widespread. As such a security system, it has a security device connected to a security sensor arranged in a monitoring target such as a house, and a monitoring center connected to the security device via a communication network, and the security status of the security device is It is known that when a security sensor outputs a detection signal in the security set mode, the security device outputs an alarm or notifies a remote monitoring center.

  In such a security system, the security status of the security device is the security set mode in which the user operates the security device with an ID card or the like, or the release mode in which the security of the monitoring target is released. Can be switched to.

  However, in such a conventional security system, when the surveillance area becomes unattended, such as when going out, it is necessary to operate the security device and set it to "security set mode", and forgot to operate and went out In some cases, there was a problem that the surveillance area became unwarmed.

Therefore, Patent Document 1 has been proposed as a solution to such a problem. In Patent Document 1, the supervisor of the monitoring area remotely calls the security device, inputs the ID number by operating the push button of the telephone, and inputs the command for changing the security status, An alarm system is disclosed that can be changed remotely.
JP 2000-295592 A

  However, since the alarm device of Patent Document 1 described above can directly change the security status of the security device remotely from the telephone, the security can be “released” by an unauthorized operation of a person who knows the ID number. There is a problem that the security is low. Even if there is a user in the monitoring area, it may be set to “security start” by a remote operation without noticing this, and there is a possibility that false alarms may occur.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a security system and a security device that can change a security state safely and reliably based on a request from a user.

  In accordance with a request from a mobile terminal, the present invention transmits a response request signal of a security staff from a security device to a monitoring center, and permits an equipment control device to allow a security guard to enter a monitoring target. When a cancellation request from a mobile terminal or a mode change of the security state of the security device is made, the output of a signal that prohibits the security guard from entering the monitoring target and the information to the monitoring center The above-mentioned problem is achieved by performing transmission.

The security system according to the first embodiment of the present invention includes a portable terminal connectable to a communication network, a security device that guards a monitoring target, a facility control device that controls facility equipment for entering the monitoring target, A security system that is connected to a security device via a communication network and includes a monitoring center that monitors the security device and transmits and receives the control device and a predetermined control signal and information. A change request unit that generates a change request signal for requesting the security device to change the security state, and a communication unit that transmits the change request signal to the security device. A communication unit that performs data communication with the mobile terminal and the monitoring center, a monitoring unit that monitors the monitoring target, and a security mode that guards the monitoring target as a security state or a release mode that releases the monitoring target security When the mode setting unit and a change request signal are received, a response request signal requesting the dispatch of a guard to the monitoring center is sent, and the facility controller is allowed to unlock the equipment by the guard. And a change request processing unit that transmits a permission signal to be transmitted.

  In this aspect, the security device notifies the monitoring center that the change request signal has been received based on a request from the mobile terminal. At the same time, a permission signal is sent to the equipment. When a guard dispatched urgently from the monitoring center operates the equipment by the permission signal to the equipment, it becomes possible to enter the monitoring target, perform an internal inspection, and change the security mode.

In the security system according to another aspect of the present invention, the change request unit of the mobile terminal can output a request cancellation signal for canceling the security status change request based on the second predetermined operation. When receiving the request cancellation signal from the portable terminal, the change request processing unit sends a response request cancellation signal to the monitoring center and disables the unlocking operation of the facility device by the security guard against the facility control device. It is characterized by transmitting the following signal.

  In this aspect, the change of the security state due to an erroneous operation is canceled afterwards. When multiple mobile devices are used by multiple people, if the user is not aware that there are still people in the monitoring target and requests to change to the security mode, the user in the monitoring target It is possible to perform a cancel operation from the mobile terminal.

  In the security system according to another aspect of the present invention, the security device further includes a storage unit that stores the current security state and the presence / absence of a request based on the change request signal, and the change request processing unit is connected to the mobile terminal. The present security state and the presence / absence of a request are transmitted.

  In this aspect, information about the current security state and whether another person has requested change is sent from the security device to the mobile terminal. As a result, the user can determine the necessity of changing the security status after confirming the current security status and request status, and can prevent erroneous requests. A user of a portable terminal may request a change due to a difference in memory, or may request a change even if another user has already completed a change to the guard state, which can be prevented. In addition, it is possible to know that other users are currently requesting, and in this case, it is possible to prevent repeated requests.

  In the security system according to another aspect of the present invention, the mobile terminal further includes a location information acquisition unit that acquires the current location information, and the change request unit of the mobile terminal guards the acquired location information together with the change request signal. The change request processing unit of the security device transmits to the device, and when the position information received from the portable terminal is within a predetermined range with reference to the monitoring target, the change request processing unit rejects the processing when the change request signal is received. And

  In this aspect, the security state change request is rejected from the portable terminal near the monitoring target. If it is close to the monitoring target, it is common for the user to go to the monitoring target himself and change the security state by himself. Therefore, in such a usage mode, there is a possibility of unauthorized use. In the security system, security is the most important, and security is improved by refusing a change request according to such a usage pattern.

The security device according to the first aspect of the present invention, the mobile terminal possessed by the user and the monitoring center,
A communication unit that communicates via a communication network, a monitoring unit that monitors a monitoring target, a mode setting unit that sets a security mode that guards the monitoring target as a security state or a release mode that releases the monitoring target security mode; When the change request signal for requesting the change of the security state is received from the mobile terminal, the equipment by the security guard sends a response request signal to the monitoring center and allows the security guard to enter the monitoring target. And a change request processing unit for sending a permission signal for permitting the unlocking operation of the device .

  According to the present invention, in response to a request from the mobile terminal, the security device transmits a countermeasure request signal to the monitoring center, and transmits a permission signal that permits the security guard to enter the monitoring target to the facility control device. Thus, it is possible to prevent the switching of the security state due to unauthorized access, and it is possible to provide a security system capable of changing the security state by remote operation while maintaining high security.

  Hereinafter, the security system of the present invention will be described in detail with reference to the drawings.

In FIG. 1, only two portable terminals 30 are shown, but it is possible to configure so that a larger number of portable terminals 30 can access one monitoring target. FIG. 1 illustrates a schematic configuration of the mobile terminal 30.

<About the overall configuration of the security system>
The security device 10 is a device installed in the monitoring target, and monitors the inside of the monitoring target by various sensors arranged in the monitoring target, and notifies the monitoring center 40 via the communication network 60 when an abnormality occurs. .

  The monitoring center 40 is provided with a security management device for monitoring the state of the security device 10 and instructing a guard's dispatch command and other necessary actions if there is an abnormality, various databases, and the like.

  The portable terminal 30 can access the security device 10 via the communication network 60, and can confirm the current security status, request a security status change, and the like. The authentication center 50 is constituted by an authentication server or the like, and authenticates whether or not the access request from the portable terminal to the security device is a request from a legitimate authorized person. The authentication center 50 may be provided in an Internet connection provider, an authentication service providing company, or the like, or may be provided in the monitoring center 40 or the security device 10. Hereinafter, each device will be sequentially described in detail.

<About mobile devices>
The mobile terminal 30 is connected to the security device 10 via the communication network 60. In this case, a generally available general technique can be used for the type of communication network, the communication protocol, the switching facility, the facility of the connection service company, and the like. When there is a connection request for the portable terminal 30, the ID number or the like is confirmed by a predetermined authentication server 50, and the access authority to the security device 10 is confirmed. When IPv6 is widely used, the access mode from the mobile device 30 to the security device 10 can be changed as appropriate according to the communication environment, such as direct access from the mobile terminal 30 to the security device 10.

  The portable terminal 30 includes a wireless communication unit 31, a control unit 32, a display unit 34, an operation unit 35, and a storage unit 36. The user of the mobile terminal 30 can request the security device 10 to check the security status and change the security status based on the operation of the operation unit 35. These requests are made by operating the operation unit 35. When there is a change request based on the operation of the operation unit 35, the change request unit 33 performs processing such as generation of a connection request to the security device 10, a change request signal, and the like. Transmission / reception of connection requests, various signals and data is performed via the wireless communication unit 31 and the communication network 60.

  As the mobile terminal 30 used in the security system 1, for example, a terminal having a communication function such as a mobile phone, a PDA, or a PC can be used. In this case, by installing a control program for performing the above-described functions in these devices, the device can function as the portable terminal of the present invention. When authentication such as an ID number is permitted and connection with the security device 10 is established, the mobile terminal 30 can transmit and receive data to and from the security device 10 via the communication network 60. In addition, in FIG. 1, the example by radio | wireless communication is shown. As described above, the mobile terminal 30 is preferably capable of wireless communication, but may be configured to communicate with the security device 10 by wire.

  The user can operate the operation unit 35 of the portable terminal 30 to transmit a confirmation request signal to the security device 10 so that transmission of current information such as the current security status can be requested. When there is a request for transmission of current status information, the security device 10 transmits information such as the current security status to the mobile terminal 30. The portable terminal 30 will display on the display part 35, if the information regarding the received security state is received. With this display, the user can check the current security state of the security device 10.

  The user can prevent an erroneous change request due to a memory difference or the like by requesting the security device 10 to change the security status by operating the operation unit 35 after confirming the security status. When there is a change request, the change processing unit 33 transmits a change request signal to the security device 10 in response to the change request. When the security device 10 receives the change request signal, the security device 10 executes a process for changing the security state. The user can further cancel the security state change request by operating the mobile terminal 30. The change request processing unit 33 transmits a request cancellation signal to the security device 10 when there is a cancellation request operation.

  The request from the mobile terminal 30 is only a request for changing the security status and a request for canceling the security status, and when connected to the security device 10, the current security status data is always acquired and displayed on the mobile terminal 30. It is also possible to adopt a configuration in which a change request signal is transmitted after confirming with the user whether or not to proceed to this step. As a result, a change request is always made after confirming the current security state, and erroneous operations can be suppressed.

<About security equipment>
The security device 10 is installed on a monitoring target. The monitoring target is an area to be guarded, and includes various facilities such as a building or a room such as a building and a condominium, and various objects can be monitored. The security device 10 includes a control unit 11, a network communication unit 12, a storage unit 13, a mode setting unit 14, an internal communication unit 15, and a detection unit 16 connected thereto. The control unit 11 includes a CPU, a register, various logic circuits, and the like, and performs various functions necessary for the security device 10 based on a control program, control data, and the like stored in a storage unit 13 including a ROM, a RAM, and the like. provide.

  The function of the control unit 11 will be described in more detail with reference to FIG. FIG. 2 is a functional block diagram of the entire control apparatus 10 in which main functions of the control unit 11 are represented by a functional block diagram. The control unit 11 includes a main control unit 21, an abnormality processing unit 22, a mode setting processing unit 23, a change request processing unit 24, and a communication control unit 25. The main control unit 21 controls the entire security device 10.

  The abnormality processing unit 22 determines the presence or absence of an abnormality based on the signal input from the detection unit 16. Various sensors such as a smoke detector, a heat detector, a gas leak detection sensor, an emergency call button, and an intrusion sensor are connected to the detection unit 16. When the abnormality processing unit 22 determines that an abnormality has occurred when the security state is a “security set mode” described later, the abnormality processing unit 22 notifies the monitoring center of the abnormality via the communication control unit 25, the network communication unit 12, and the communication network 60, and The permission signal (unlocking permission signal) which permits a guard to enter the monitoring object is sent to the security equipment device 17 which will be described later. When it is determined that the abnormal state has been properly recovered, a recovery signal is transmitted to the monitoring center, and transmission of the unlocking permission signal to the security equipment device 17 is stopped, or a security guard enters the monitoring target. Send a signal to make it impossible.

  The mode setting processing unit 23 changes the security state based on the signal from the mode setting unit 14. The mode setting unit 14 is an operation unit that sets or cancels security start by a user operation using an ID card or the like. Usually, an input device such as a card reader or a key input unit is provided. When the user no longer exists in the monitoring target (when unattended), the user sets the security status to “security set mode (security mode)” that guards the monitoring target, and is within the monitoring target of the security set mode. Set to "security release mode" that releases the security of the monitoring target when the user enters (when manned). These security mode settings are stored in the storage unit 13 and transmitted to the monitoring center 40.

  The change request processing unit 24 receives a security state change request from the mobile terminal 30 and performs processing necessary for changing the security state. When the change request processing unit 24 receives the change request signal from the mobile terminal 30, the change request processing unit 24 stores in the storage unit 13 that the change request is being made (change request state “ON”). In addition, a countermeasure request signal is output to the monitoring center 40 and an unlocking permission signal as a permission signal is transmitted to the security equipment device 17 described later.

  Further, when the change request processing unit 24 receives the request cancellation signal from the portable terminal 30 during the change request, the change request processing unit 24 sets the change request state stored in the storage unit 13 to “OFF” and sends a response request cancellation signal to the monitoring center 40. Output. Furthermore, the transmission of the unlocking permission signal to the security equipment device 17 is also stopped. Also, if the security state is changed during the change request, the change request state is set to “OFF” and the monitoring center 40 determines that the security state has changed the security state by a regular procedure based on the change request. The countermeasure request cancellation signal is output, and the transmission of the unlocking permission signal to the security equipment device 17 is stopped.

  Furthermore, when the change request processing unit 24 receives a confirmation request signal for requesting confirmation of the current security state from the portable terminal 30, the change request processing unit 24 reads information on the current security state and the change request state from the storage unit 13, It transmits to the portable terminal 30. As described above, when a change request signal is received, it is also possible to first transmit information on the current security state and whether or not there is a change request.

  The communication control unit 25 performs communication control for the communication network 60 and internal communication. Communication with the portable terminal 30 and the monitoring center 40 is performed via the network communication unit 12 under the control of the communication control unit 25. Further, as internal communication, an unlock permission signal is sent to the security equipment device 17 through the internal communication unit 15 under the control of the communication control unit 25.

<About security equipment>
The security equipment 17 includes a key box locking device in which a management key or the like is stored, or an equipment 19 including a locking device such as an electric lock door of an entrance / exit that is prohibited from being entered / exited by a person other than a predetermined authority. It is the equipment control part 18 which controls. A key box is a box in which a master key such as a management key is stored. When an abnormality occurs, security guards take out the management key from the key box, enter the monitoring target, and check whether there is an abnormality. Further, when an electric lock door is provided as the equipment 19, a guard or the like unlocks the electric lock and enters the monitoring target when there is an abnormality, and checks whether there is an abnormality.

  A security equipment device 17 is connected to the security device 10 via an internal communication unit 15. The security device 10 sends an unlocking permission signal (permission signal) to the security equipment device 17 when the abnormality processing unit 22 determines that an abnormality has occurred or when the change request processing unit 24 receives a change request. . The security equipment device 17 is provided with an operation unit (not shown) for performing unlocking operation of the equipment, and when an abnormality occurs, a security guard operates the operation unit to operate a key box or an electric lock door. Unlock facility equipment. Only when the unlocking permission signal is received from the security device 10, the equipment control unit 18 accepts the unlocking operation of the security equipment equipment 19. As long as there is no unlocking permission signal (permission signal), the facility control unit 18 does not permit even a guard to enter the monitoring target by operating the security facility device 17. Therefore, unless the unlocking permission signal (permission signal) is transmitted from the security device 10, the security guard cannot enter the monitoring target.

  In this example, the equipment 19 is not limited to the above-described locking device such as a key box or an electric lock door, and may be any equipment as long as it is at least entered into the monitoring target.

<About the monitoring center>
The monitoring center is a facility equipped with a server system operated by a security company, and the controller constantly monitors the monitoring target. The monitoring center also includes a database for storing and managing information of the security device 10 to be monitored, that is, a management number of the security device 10, a user's name, address, telephone number, past handling history, and the like. In the monitoring center, information on the monitoring target to be dealt with based on the abnormality signal or response request signal received from the security device is displayed on the display, and confirmation processing for the user or instructions for handling the guard to the monitoring target (the dispatch command) ) And other necessary measures. In addition, when the monitoring center receives a signal indicating restoration of the abnormality or cancellation of the request from the monitoring target that has received the abnormality signal or the countermeasure request signal, the monitoring center ends the processing related to the abnormality signal or the countermeasure request signal.

<Operation of the security system associated with change request processing>
FIG. 3 is a diagram illustrating the mutual operations of the mobile terminal 30, the security device 10, and the monitoring center 40 when the change request process is performed. FIG. 3 is an example in which the above-described authentication center 50 is provided in the security device 10, and an example in which the security device 10 performs authentication in response to a connection request from the mobile terminal 30 and returns current information when the authentication is completed. Is shown.

  When there is a connection request from the portable terminal 30 (70), the security device 10 authenticates the connection requester using an ID number or the like, and establishes a connection if there is no problem with the authentication (80). At the same time, information on the current state, such as the current security state stored in the storage unit 13 and the presence / absence of a change request, is output to the portable terminal 30 (81).

  When the portable terminal 30 receives the current state information, the portable terminal 30 displays the information on the display unit 34 (FIG. 1). 4A and 4B show two display examples 65a and 65b of the display screen of the mobile terminal 30. FIG. Display example 65a is a security release mode, and shows a state where there is no change request. Display example 65b indicates that there is a change request although it is currently in the security release mode. When the current mode is the security set mode, the security status is displayed as “security set” or “set”.

  In the case of the display example 65a, an operation for requesting a change of the security state is performed by clicking “request” of <operation> (72), and a change request signal is transmitted to the security device 10 (73). In the case of the display example 65b, since the change request has already been made, the change request cancel operation is performed by clicking “Cancel” in <Operation>, and a request cancel signal is transmitted to the security device 10 (not shown). ) In the display examples 65 a and 65 b, by clicking “update” of <operation>, an operation for requesting the current state confirmation of the security device 10 is performed, and a current state confirmation signal is transmitted to the security device 10. Then, the security device 10 outputs the current security status and the presence / absence of a change request to the mobile terminal 30, and the display screen of the mobile terminal 30 is updated.

  Upon receiving the change request signal (82), the security device 10 performs change request processing (83), transmits a countermeasure request signal to the monitoring center 40 (84), and sends an unlocking permission signal to the security equipment device 17 (85).

  Upon receiving the response request signal (90), the monitoring center 40 outputs request information (display output, voice output, etc.) to the display unit (not shown) of the monitoring center 40 (91), and Inform the fact of the request from the specific monitoring target and the content of the request. When the controller confirms that it is a countermeasure request accompanying the change request, it issues a dispatch command to the monitoring target requested by the guard. In addition, you may comprise so that the monitoring system of the monitoring center 40 may issue the dispatch command with respect to a change request with respect to the output apparatus of a guard's waiting room based on a response request signal, without passing through a controller. At this time, it is preferable that the monitoring center 40 notifies the user that a change in the security status of the monitoring target has been requested by telephone communication or electronic mail.

  The security guard is dispatched to the monitoring target, operates the operation unit of the security equipment device 17 to unlock the key box, etc., and takes out the master key, or unlocks the electric lock on the electric lock door and remains within the security target. to go into. At this time, since the unlocking permission signal is sent to the security equipment device 17, the security guard can unlock the key box and the electric lock door by a predetermined operation. The security guard enters the monitoring target and checks whether there is any abnormality in the monitoring target, and then changes the security status (security release mode → security set mode, security set mode → security release mode) (86). When the security state is changed, the change request processing unit 24 executes a process for ending the change request (87). The change request processing unit 24 outputs a countermeasure request cancellation signal to the monitoring center 40 (88), and stops sending an unlocking permission signal to the security equipment device 17 (89).

  Similarly, when the security device 10 receives a request cancellation signal from the portable terminal 30 (86), the change request processing unit 24 similarly executes a request termination process (87) and transmits a countermeasure request cancellation signal ( 88) The transmission of the unlocking permission signal is stopped (89). When the monitoring center 40 receives the response request cancellation signal (93), the monitoring center 40 stops outputting the request information and ends the processing related to the request (94).

  In the above description, an example of a change request from the security release mode to the security set mode has been described using FIG. 4, but a change from the security set mode to the security release mode can also be requested from the portable terminal 30. For example, when a card or the like for entering a monitoring target is forgotten at home, it may be necessary to change from the security set mode to the security release mode.

<Security device change request processing procedure>
FIG. 5 is a flowchart illustrating an example of the change request processing procedure of the security device 10. First, a change request process is started by receiving a connection request from the portable terminal 30 (S101). When there is a connection request from the portable terminal 30 (S101; Yes), the change request processing unit 24 transmits information such as the current security state and presence / absence of a change request stored in the storage unit 13 to the portable terminal 30 ( S102). Thereafter, it is confirmed whether a change request signal has been received (S103) or a request cancellation signal has been received (S104). At this time, if a request cancellation signal is received (S104; Yes), it is determined based on information in the storage unit 13 whether or not a change is currently requested (S111). End the change process. On the other hand, if a change request is being made (S111; Yes), a request cancellation process is performed (S109). In S103 and S104, when no signal is received from the mobile terminal 30 for a predetermined time (S103; No, S104; No), it is preferable to release the connection with the mobile terminal 30 and end the process.

  When the change request signal is received from the portable terminal 30 (S103 Yes), the change request processing unit 24 transmits a countermeasure request signal to the monitoring center 40 (S105). Next, an unlocking permission signal is sent to the security equipment device 17 (S106). Thereafter, it is confirmed whether a request cancellation signal has been received (S107) or whether the security status has been changed by the security guard (S108). When the request cancellation signal is received from the portable terminal 30 (S107; Yes), the change request processing unit 24 transmits a countermeasure request cancellation signal to the monitoring center 40 (S109), and further unlocking permission signal for the security equipment device 17 Is stopped (S110), and the change request process is terminated. When the security status is changed (S108; Yes), it is considered that the security status has been changed normally by the security guard, and similarly, a countermeasure request cancellation signal is transmitted (S109), and an unlocking permission signal is displayed. The transmission is stopped (S110), and the change request process is terminated.

  As described above, according to the present invention, according to the change request from the mobile terminal, the security state change process is performed under the control of the monitoring center, so that an unauthorized person who knows the ID number can easily detect the security state. Therefore, it is possible to provide a highly secure security system while improving customer convenience.

  In addition, according to the embodiment of the present invention, since it is possible to change the security state after confirming whether the current security state and a change request are being made, an error occurs due to a difference in memory or a double operation of multiple persons. It is possible to prevent erroneous operations such as changing the security state. Further, in this embodiment, when the security state is likely to be changed by mistake, the change request may be canceled by transmitting a request cancellation signal from the mobile terminal side possessed by another user during the change request. it can. In preparation for such a case, when changing the security state from the mobile terminal, it may be configured to actively notify other mobile terminals that the change is being requested by voice or vibration. it can.

<Other embodiments>
Position information acquisition means such as GPS is provided in the portable terminal, and when the change request signal is transmitted from the portable terminal to the security device, the position information acquired by the portable terminal and the acquisition time information of the position information are attached and transmitted. The authentication server or the security device has a configuration in which the difference between the position information transmitted from the mobile terminal, the acquisition time of the position information, and the current time is within a predetermined time, and the position information is separated from the monitoring target by a predetermined distance or more. Only when the position is the same position, the connection between the portable terminal and the security device is accepted, or the change request is accepted.

  In this embodiment, the change of the security state from near the monitoring target is rejected. Thereby, it is possible to further improve the security of the security system according to the present invention. In other words, if you are near the monitoring target, you should move to the monitoring target and change the security status yourself. Since the possibility of unauthorized use is considered, this type of usage is excluded. Also, if the difference between the position acquisition time and the current time is large, the position information is acquired at a distance, and the case where a change request is made near the monitoring target is excluded.
