Description

  The present invention relates to a security system in which a security target facility and a security company are connected by a communication line such as a telephone line network or an Internet network.

  In general, in a security system in which a security target facility and a security company are connected by a communication line or the like, a sensor for detecting an intruder (human body) is provided at the entrance / exit of the security target facility. It is connected to a controller that is installed in the facility and can perform warning and release operations of the security system. If a security guard or a resident of a facility (such as a security guard) tries to exit the doorway by setting the controller in the facility to be in a warning state, or entering the facility in a warning state from the doorway, a predetermined range of the doorway Even if a sensor installed inside detects a guard or the like, an alarm is not issued for a certain time, that is, the alarm time is delayed by a certain time.

Conventionally, the delay setting of the alarm time at the entrance / exit of the entrance / exit of the facility to be guarded is performed by setting a predetermined time in advance in a timer (delay timer) provided in the controller in the facility. In addition, as a gazette regarding this kind of security system, there exists patent document 1, for example.

  However, in such a security system, the alarm time for entry / exit is set according to a predetermined time set in advance in a delay timer provided in the controller. The security system of the security system is sufficiently secured because there is a possibility that a person will reach the controller position within a predetermined time and destroy the controller to make an alarm action (notifying the security company or ringing the bell) It is difficult to increase.

  The present invention has been made in view of such circumstances, and its purpose is to reliably perform a timer operation for an alarm time at the time of entry / exit to suppress the prevention of destruction by intruders and the entry / exit of security guards, etc. It is an object of the present invention to provide a security system that can prevent misinformation at the time and sufficiently enhance security.

  In order to achieve such an object, the invention according to claim 1 of the present invention is a communication between a security target facility and a security company having a controller capable of warning / release operation and a sensor arranged at an entrance and capable of detecting a human body. In the security system connected by a line, the controller of the facility to be guarded includes a first timer that operates when a predetermined signal is received from the communication line, and a detection signal from the sensor during the operation of the first timer. A second timer that operates when an input is received, and transmits a warning signal to a security company when the controller is not released before the second timer expires.

  The first timer preferably operates when a predetermined signal set in advance is received from a telephone line network connecting the security target facility and the security company, as in the invention described in claim 2. In this case, the predetermined signal is preferably a preset telephone number as in the invention described in claim 3. The first timer is activated when a predetermined signal set in advance is received from the Internet network connecting the security target facility and the security company, as in the invention described in claim 4. It is preferable to operate when a predetermined signal set in advance is received from a wireless remote controller provided outside the facility to be guarded. Furthermore, it is preferable that the controller returns to a warning state when no detection signal is input from the sensor during the operation of the first timer.

  According to the first aspect of the present invention, when the detection signal is input from the sensor during the operation of the first timer provided in the controller of the facility to be guarded, the second timer is operated to If the controller is not released before the time expires, an alarm signal will be sent to the security company, so use the first timer as a trigger timer, and perform the timer operation at entry / exit as two actions to delay the alarm time. The security of the security system can be sufficiently enhanced, for example, by suppressing the destruction of the controller by an intruder or by preventing the false alarm due to the entry or exit of a security guard.

  According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the first timer operates when a predetermined signal set in advance from the telephone line network is received. The first timer can be activated by making a call from a telephone terminal such as a telephone or a fixed telephone, and the operability can be improved.

  According to the invention described in claim 3, in addition to the effect of the invention described in claim 2, the first timer is activated in the case of a preset telephone number. By having it, the telephone charges can be reduced, and a cost-effective security system can be obtained.

  According to the invention described in claim 4, in addition to the effect of the invention described in claim 1, the first timer operates when a predetermined signal set in advance from the Internet network is received. The first timer can be operated by accessing the Internet network from a terminal such as a personal computer, and the operability can be improved.

  According to the invention described in claim 5, in addition to the effect of the invention described in claim 1, the first timer is received when a predetermined signal set in advance is received from a wireless remote controller provided outside the facility to be guarded. Therefore, the first timer can be operated by the operation of the outdoor remote controller, and the operability thereof can be improved. For example, an accurate response at the time of threat can be made, and the security can be further improved.

  Further, according to the invention described in claim 6, in addition to the effects of the invention described in claims 1 to 5, the controller returns to a warning state when no detection signal is input from the sensor during operation of the first timer. Therefore, the second timer for transmitting the alarm signal can be reliably operated, and forgetting to set the alarm state can be prevented to further improve the security.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 6 show an embodiment of a security system according to the present invention, FIG. 1 is a configuration diagram thereof, FIG. 2 is a block diagram of a controller, FIG. 3 is a flowchart showing an example of its operation, and FIG. FIG. 5 is an explanatory diagram of the remote controller, and FIG. 6 is a flowchart showing the operation.

  As shown in FIG. 1, the security system 1 includes a security target facility 2 such as a factory office or a general household, and a security company 3 connected to the security target facility 2 through a telephone line network 4 and an Internet network 5. The security target facility 2 configured includes a sensor 6 such as a heat ray sensor disposed at an entrance to the facility 2 and a controller 7 to which the sensor 6 is connected.

  As shown in FIG. 2, the controller 7 includes a control unit 8 having a CPU 9 and a timer 10 composed of a first timer 10a and a second timer 10b, which will be described later. A power input unit is provided on the input side of the control unit 8. 11 and an operation unit 12 such as an operation panel and a sensor input unit 13 to which the sensor 6 is connected are connected. On the output side of the control unit 8, a display unit 14, an audio output unit 15, a relay output unit 16 and the like are provided. It is connected. Further, the control unit 8 is connected to a telephone line unit 17 such as a modem to which the telephone line network 4 is connected and an IP unit 18 to which the Internet network 5 is connected, and a remote control input unit 19 to which a remote controller 22 to be described later is connected. And the wireless input / output unit 20 and the storage unit 21 are connected.

  As shown in FIG. 1, the security company 3 also includes a controller 23 having a control unit (not shown), a wireless input / output unit, and the like that are substantially the same as the controller 7, a monitoring table (not shown), and the like. Various signals transmitted from can be constantly monitored. Further, a terminal 24 such as a mobile phone or a fixed telephone is connected to the telephone line network 4, and a terminal 25 such as a mobile phone or a personal computer is connected to the Internet network 5.

  Next, an example of operation | movement of the security system 1 comprised in this way is demonstrated based on the flowchart of FIG. Note that the flowchart shown in FIG. 3 is automatically executed according to a program stored in advance in the storage unit 21 of the control unit 8. First, when the security system 1 is turned on, the program starts (S100), and it is determined whether or not it is in a warning state (S101), and this determination S101 is repeated until "YES" is reached. If "YES" is determined in the determination S101, that is, if the security system 1 is set to a warning state by the operation unit 12 of the controller 7, it is determined whether or not there is a timer trigger signal (S102).

  The timer trigger signal in this determination S102 is a predetermined signal input to the controller 7 from the telephone line network 4, the Internet network 5, etc. For example, in the case of the telephone line network 4, it is output as shown in FIG. The That is, when the program starts (S201), it is determined whether or not there is an incoming call (S202). If the determination is "YES" in S202, that is, for example, a security guard or the like is at the terminal 24 such as a mobile phone or a landline phone. When a call is made to the controller 7, it is determined whether or not the telephone number is authenticated (S203).

  In this determination 203, for example, a predetermined telephone number is stored in the storage unit 21 in advance as in the number display function, and when the stored telephone number matches the incoming telephone number, authentication OK is performed and a timer trigger signal is received. The authentication program is output (S204) to end (S205). If the received telephone number does not match the stored telephone number and the determination in S203 is “NO”, the process immediately ends (S205) or returns to determination S202 to wait for the next incoming call. Become. That is, the timer trigger signal is output only when the stored telephone number is received.

  FIG. 4 shows a telephone authentication method using the telephone line network 4. Even when the Internet network 5 is used, a predetermined signal such as an address input from the terminal 25 to the controller 7 is stored in the storage unit 21 in advance. Only when it matches the stored signal, a timer trigger signal is output as authentication OK.

  Then, as shown in FIG. 3, when “YES” is determined in determination S <b> 102 and a timer trigger signal is input, the first timer 10 a of the control unit 8 is started (S <b> 103). It is determined whether there is an input (S104). If “NO” in this determination S104, that is, if no detection signal is input from the sensor 6 after the first timer 10a is started, it is determined whether or not the first timer 10a is timed up (S105). If “NO” in this determination S105, the process returns to the determination S104. If “YES” in the determination 105, that is, if the detection signal is not input from the sensor 6 while the first timer 10a is operating (counting). Returning to S101, the input of the next timer trigger signal is awaited.

  On the other hand, if “YES” in the determination S104, that is, if a detection signal is input from the sensor 6 during the operation of the first timer 10a, the second timer 10b of the control unit 8 starts (S106) and is released. It is determined whether or not there is (S107). This canceling operation is performed by the operation unit 12 of the controller 7. If “NO” in the determination S107, it is determined whether or not the second timer 10b is up (S108). If “NO” in this determination S108, the process returns to the determination S107. If “YES” in the determination S108, that is, if the release operation is not performed during the operation of the second timer 10b, an alarm signal is transmitted to the telephone line network 4. Or the like is transmitted to the controller 23 of the security company 2 (S110). If “YES” in the determination S107, that is, if the release operation is performed by the operation unit 12 during the operation of the second timer 10b, the warning state of the security system 1 is released (S109), and a series of programs Is the end (S111).

  That is, according to this flowchart, the first timer 10a is started by the timer trigger signal, and when the detection signal is input from the sensor 6 during the operation of the first timer 10a, the second timer 10b is started. The warning state can be released by performing a release operation with the operation unit 12 while the timer 10b is operating, and the alarm time can be delayed by the set time of the timer 10b by two actions of the first timer 10a and the second timer 10b. . In addition, each timer time of the 1st timer 10a and the 2nd timer 10b can be set to predetermined | prescribed time according to forms, such as the distance from the entrance / exit of the guarded facility 2, to the controller 7. FIG.

  In the above flowchart, the case where the timer trigger signal is input from the terminals 24 and 25 of the telephone line network 4 and the Internet network 5 has been described. For example, the signal of the remote controller 22 connected to the controller 7 is It can also be used. In this case, as shown in FIG. 5, an indoor remote controller 22a and an outdoor remote controller 22b are used as the remote controller 22 connected to the controller 7, and at least the outdoor remote controller 22b is wireless.

  Then, as shown in FIG. 6, when the program is started (S301), it is determined whether the alarm release switch is turned on by operating the indoor remote controller 22a (or the outdoor remote controller 22b) (S302). If “YES”, it is determined whether or not the outdoor remote controller 22b (or the indoor remote controller 22a) is turned on (S303). When both determinations S302 and S303 are “YES”, a timer trigger signal is output (S304) and the end (S305) is reached. That is, unless both the indoor remote controller 22a and the outdoor remote controller 22b are turned on, the first timer 10a does not start and the alarm time cannot be delayed.

  Thus, in the security system 1 of the above embodiment, the controller 7 of the security target facility 2 is provided with the first timer 10a and the second timer 10b, and the detection signal of the sensor 6 is output during the operation of the first timer 10a. When there is an input, the second timer 10b is activated, and if the controller 7 is not released before the time is up, an alarm signal is sent to the security company 3, so the first timer 10a is used as a trigger timer, The alarm operation can be delayed by the time of the timer 10b with the timer operation at the time of leaving as two actions of the first timer 10a and the second timer 10b. As a result, it is possible to suppress the destruction of the controller 7 by an intruder or to prevent a false alarm due to the entry or exit of a guard or the like, and to sufficiently improve the security of the security system 1.

  Further, since a timer trigger signal for starting the first timer 10a of the controller 7 can be obtained by operating the terminals 24 and 25 of the telephone network 4 and the Internet network 5 and the remote controller 22, the operability at the time of releasing the alert is improved. be able to. In particular, since the first timer 10a operates when the controller 7 receives a predetermined signal set in advance from the telephone line network 4 or the Internet network 5, the operation of the terminals 24 and 25 such as a mobile phone, a fixed phone, or a personal computer is performed. Thus, the first timer 10a can be operated, and its operability can be further improved. Further, if a timer trigger signal can be obtained by operating the two remote controllers 22a and 22b indoors and outdoors, even if the intruder is threatened outdoors, for example, only the operation of the outdoor remote controller 22b is wary. Since it is not released, it is possible to further improve the security and to appropriately deal with threats.

  Further, when the first timer 10a is activated only when a telephone number is set in advance when the telephone line network 4 is used, for example, by providing the controller 7 with a number display function, a telephone charge is provided. It is possible to obtain a security system 1 that is advantageous in terms of cost. Further, when the detection signal is not input from the sensor 6 during the operation of the first timer 10a, the security system 1 automatically returns to the warning state. Security can be further improved.

  Note that the specific configuration of the controller 7 and the configuration of the timer 10 in the above embodiment are merely examples. For example, one of the first timer 10a and the second timer 10b is set as a fixed time, and the other can be changed in time. For example, the present invention can be changed as appropriate without departing from the scope of the invention.

  The present invention is not limited to a system in which a security target facility and a security company are connected by both a telephone line network and an Internet network, and can also be used in a system in which one of them is connected.
