A block diagram and FIG. 4 are flowcharts showing an example of the operation.

  As shown in FIG. 1, a security system 1 includes a security target facility 2 such as a factory office, a store, and a general home, and a security target facility 2 and a communication line 4 such as a telephone line network, the Internet network, or radio. It consists of a connected security company 3 etc. The security target facility 2 includes a sensor 5 such as a heat ray sensor disposed at the entrance to the security target facility 2, a notification device 6 to which the sensor 5 is connected, and the security company 3 includes a center device. 7 is provided.

  As shown in FIG. 2, the notification device 6 includes a control unit 8 having a CPU 8a, a timer 8b, a counter 8c, and the like. On the input side of the control unit 8, a power input unit 9 and an operation unit such as an operation panel are provided. 10 and the sensor input unit 11 to which the sensor 5 is connected are connected. On the output side of the control unit 8, a display unit 12, an audio output unit 13, a relay output unit 14, and the like are connected. The control unit 8 is connected to a telephone line unit 15 such as a modem to which the telephone line network is connected, an IP unit 16 and a wireless input / output unit 17 to which the Internet network is connected.

  Further, the control unit 8 is connected to a remote control input unit 18 to which a remote controller 20 (see FIG. 1) is connected, and a storage unit 19 in which a program, a state of the sensor 5 and the like described later are stored. The control unit 8 performs predetermined processing based on the detection signal of the sensor 5 input to the sensor input unit 11, the operation signal of the remote controller 20, the timer 8b, the counter 8c, etc. Via the wireless input / output unit 17, the signal is transmitted to the center device 7 or a predetermined signal is received from the center device 7.

  As shown in FIG. 3, the center device 7 of the security company 3 includes a receiving device 21 and a processing device 22, and the receiving device 21 includes an input-side communication unit 23, an output-side communication unit 24, and The processing device 22 includes a control unit 25, and includes a communication unit 26, a control unit 27, a display unit 28, an operation unit 29, a storage unit 30, and the like. The communication unit 23 of the reception device 21 is connected to the wireless input / output unit 17 of the notification device 6, and various signals transmitted from the notification device 6 are received by the reception device 21, and the received signals are processed by the processing device 22. Thus, the security target facility 2 can be constantly monitored.

  Next, an example of operation | movement of the security system 1 comprised in this way is demonstrated based on the flowchart of FIGS. The flowchart shown in FIG. 4 shows the operation of the reporting device 6 and is automatically executed by the program stored in the storage unit 19.

  First, as shown in FIG. 4, when the power of the reporting device 6 is turned on, the reporting device 6 starts a program (S100), and determines whether there is a telephone call (S101). The telephone number determined at this time is a telephone with a predetermined telephone number registered in advance, for example, in the center device 7, and if “YES” in the determination S101, that is, the monitor of the center device 7 reports from the predetermined telephone. When a telephone call is made to reversely control the device 6 and the notification device 6 receives an incoming call, the timer 8b is set and the counter 8c is incremented (S102) to determine whether or not the count is confirmed (S103). Is done.

  The count confirmation in this determination S103 is a confirmation of whether or not the number of incoming calls by the telephone is the number of times (for example, three times) set in advance in the counter 8c. If “NO” in the determination S103, that is, the telephone call If it is less than three times, the process returns to step S101. On the other hand, if “YES” in the determination S103, that is, if there is a telephone call three times from a predetermined telephone of the center device 7, the center device 7 is dialed (S104) and the notification device 6 and the center device 7 are connected. A telephone connection is made (S105).

  With the telephone connection in steps S104 and S105, the reverse control permission signal is transmitted from the reporting device 6 to the center device 7. In this state, data including commands to be described later is transmitted / received (S106). Thus, the reporting device 6 is reversely controlled by the center device 7, and when this reverse control is completed, the series of programs is ended (S109). The reverse control in step S106 is performed by various commands such as warning, release, patrol start, patrol end, cleaning start, cleaning end, sensor emergency start, sensor emergency end, battery replacement reset, and the like. .

  On the other hand, if “NO” in the determination S101, that is, if there is no telephone call, it is determined whether or not the timer 8c is up (S107). If “YES” in this determination S107, that is, if there are not three telephone calls within a predetermined time (for example, 30 seconds), the counter 8c is cleared (S108) and the end (S109) is reached. . Further, if “NO” in the determination S107, that is, if there is no telephone call and the timer 8b has not timed out, the end (S109) is also reached.

  In other words, when a call is made from a predetermined telephone of the center device 7, the notification device 6 does not connect to the center device 7 by telephone for a maximum of two times within the preset 30 seconds, for example, 3 When there are round calls, a telephone connection is established, and this telephone connection enables reverse control of the reporting device 6 from the center device 7. In the case of this example, the reverse control permission state can be automatically obtained by the time and the number of times set in the control unit 8 of the notification device 6, and the reverse control is performed even when there is no person in the vicinity of the notification device 6. It becomes possible.

In the above example, the reverse control permission signal is transmitted from the reporting device 6 to the center device 7 by three calls from the center device 7. However, the present invention is not limited to this example, and for example, FIGS. The flowchart shown in FIG. First, the flowchart shown in FIG. 5 shows the operation of the center device 7. When the center device 7 is turned on, the program starts (S200), and a predetermined signal reception process from the notification device 6 (S201). After that, it is determined whether there is a standby control signal (reverse control permission signal) in the signal (S202). In this standby control , in order to transmit security information or the like from the reporting device 6 to the center device 7, the control registered in advance using the connected communication line 4 is executed. Say to reserve control in preparation for the connection.

  If there is standby control and the determination in step S202 is “YES”, a standby control process (S203) is performed, and a predetermined signal is transmitted to the reporting device 6 to perform a reverse control process (S204). Is the end (S205). In the case of this example, the reverse control permission state is automatically obtained by effectively utilizing the standby control signal added to the security system 1. Note that if the standby control and the reverse control are the same control, only one of steps S203 and S204 is sufficient.

  The flowchart by the center device 7 shown in FIG. 6 is applied to, for example, the above-described security system that does not have the standby control function, and the notification device 6 has a notification unit such as an operation button indicated by a two-dot chain line in FIG. 31 is provided. Then, as shown in FIG. 6, when the program starts (S300), the center device 7 determines whether or not an operation signal (reverse control permission signal) from the reporting unit 31 has been received (S301). In the case of “YES”, that is, when the reporting unit 31 is operated by a guard or a resident and the center device 7 receives an operation signal, reverse control processing (S302) is performed and a series of programs is ended (S303). . This example is applied when there is a person in the vicinity of the notification device 6.

  Thus, in the security system 1 of the above embodiment, when the reporting device 6 receives a signal of a predetermined condition set in advance from the center device 7 via the communication line 4, the center device 7 is allowed to perform reverse control. Since the signal is transmitted, the center device 7 can perform the reverse control in response to the reverse signal permission signal. As a result, during reverse control, the signal is not received by a telephone device such as a telephone or FAX connected to the telephone line unit 15 of the reporting device 6, and the telephone device of the reporting device 6 is connected. Regardless, the reverse control of the reporting device 6 by the center device 7 can be performed accurately and easily.

  In particular, by using a signal when a predetermined number of calls are received from a predetermined telephone of the center device 7 within a predetermined time as a reverse control permission signal, reverse control is performed even when there is no person in the vicinity of the notification device 6. The permission state can be obtained automatically, and the reliability of the security system 1 can be sufficiently enhanced.

  In addition, if the standby control signal added to the security system 1 is used as the reverse control permission signal, the reverse control permission state can be easily obtained using the existing security system. The configuration of the system 1 can be simplified. Furthermore, if the reverse control permission state is obtained by operating the reporting unit 31 provided in the reporting device 6, it can be suitably used when there is a person in the vicinity of the reporting device 6, and by using these various signals It is possible to easily obtain the optimum reverse control permission state according to the situation of the security target facility 2. In addition, since the notification device 6 is provided with a timer 8b, a counter 8c, and the like and can be dealt with by a program change or the like, for example, a timer already provided in the notification device 6 or the like can be used, which is advantageous in terms of cost. The security system 1 can be constructed.

  In the above embodiment, the specific configuration of the reporting device 6 and the center device 7, the flowchart showing the operation thereof, the type of the reverse control permission signal, etc. are examples. For example, as the reverse control permission signal, various addresses, etc. Various changes can be made without departing from the gist of each invention according to the present invention, such as using a signal or adopting other appropriate configurations or flowcharts.
