Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is connected to a receiving device via an automatic station joining line, and when an activation signal is input, the receiving device is called by auto dial and connected. The present invention relates to a control method for an emergency notification device that automatically issues predetermined information after the emergency call is completed.

[Prior art]

Conventionally, crime prevention information is the main monitoring information for this type of device. This indicates the closed state of each door, window, etc. that serves as an entrance/exit. When a sensor installed on each door, etc. sends out a detection output indicating that the door, etc. is open, the control circuit activates it. Starts the alarm operation as an input. However, this crime prevention information is different from other information indicating the occurrence of fire or gas leak, and when residents are doing normal activities at home, even if there is a detection output from a sensor, it may be detected as abnormal. There is no need to report it as such.

Therefore, with regard to this crime prevention information, it is common to provide a warning mode and a release mode, and to issue an alarm using the detection output as an activation signal only when the warning mode is selected.

By the way, the above-mentioned alarm/cancellation mode can be selected using, for example, a mode changeover switch provided on the operation panel, but since it is necessary to open one of the exits when going out, it is recommended to change the above-mentioned changeover switch before going out. If this happens, there is the inconvenience that it will be reported immediately. This kind of inconvenience can be avoided by, for example, installing the above-mentioned switch outside the final exit, but on the other hand, if there is a part of the door that is not fully locked on another window, etc., you may go out without noticing this. It is not possible to eliminate the risk of it being lost.

[Object and structure of the invention]

The present invention was made in view of the above circumstances, and its purpose is to prevent false alarms at the final exit, and also to issue an alarm in an emergency notification device that can confirm whether the door is completely locked or not. It provides a method.

In order to achieve such an objective, the present invention
A mode changeover switch that switches the monitoring state between warning mode and cancellation mode, a timer that starts when the mode changeover switch switches to warning mode, and a prohibition of alarm operation when a start signal is input while this timer is operating. and abnormality display means installed near the mode changeover switch and displaying an abnormal state upon input of a start signal. Hereinafter, the present invention will be explained in detail using Examples.

〔Example〕

FIG. 1 is a block diagram of an emergency notification device showing one embodiment of the present invention. This emergency notification device is connected to a receiving device, for example, a remote monitoring device installed at a security insurance company, via an automatic station connection line, and it can be used to operate various sensors, alarm/cancellation mode switches, etc. When a predetermined activation signal is input from the slave, the telephone line is captured and the receiving device is automatically dialed according to the preset dial number, and after connection, the information corresponding to the activation input is transmitted to the receiving device. It is sent as a multi-frequency signal similar to a push-button-dial signal along with the subscriber's address.

That is, in FIG. 1, an emergency notification device main body 1 is connected to a central office line L via a terminal block 2. As shown in FIG. In normal use, this main unit 1 is connected to the central office line L in parallel with this telephone TEL, but like the line protection device PD, when necessary for testing etc. It can be disconnected from the telephone TEL. 5 is a control unit equipped with a CPU;
All operations are controlled by control signals sent from this control section 5. Reference numeral 6 designates a station line circuit, 7 a network control section for controlling acquisition and release of the station line, and 8 a multifrequency signal generation section. Also, 9 and 10 are specific frequencies (1650
Hz, 2100Hz) signal; 11 is a manually operated switch; for example, a setting section is used to set a dial number and subscriber address at the time of installation; 12 is a lamp and alarm corresponding to each activation signal; - A display and operation section consisting of a display and operation panel equipped with various operators such as a release mode changeover switch. Also, 13 is a place away from the above panel,
For example, this is a remote control section that allows the mode to be switched outside the final exit, etc., and whether the mode is switched by a switch on the main body side or by this remote control section 13 is determined by a separate switch (not shown). ) can be selected. The remote control section 13 also includes a display lamp LM as described later. 14 is an input/output interface section. Detection signals from each sensor S input via the input/output interface section 14 and display operation section 1
2. The signal from the remote control unit 13 is sequentially and repeatedly scanned via the sensor input decoder 15 to the control unit 5.
be taken into account. 16 is an output driver, 17a is a power supply section, 17b is a power supply unit, 17c is a battery charging section, 17d is a battery, and 18 is an amplifier.

Here, for normal sensors, the control unit 5 constantly monitors the input status, and if there is an input, starts executing the alarm processing operation, but for the security sensor connected to a specific sensor terminal, , vigilance
The operation differs depending on the setting state of the release mode.

That is, the display operation section 12 includes a mode changeover switch 2 on a panel 20 as shown in FIG.
1 is provided. When this switch 21 is set to ``occupancy'', the release mode is selected, and inputs from security sensors provided at each door, window, etc. are not monitored. Conversely, when set to ``absent'', alert mode is selected and all inputs from each security sensor are monitored. On the other hand, if the security switch 22 is set to "Night", depending on the state of the security switch 22, if the security switch 22 is set to "Monitor", the alarm mode is set to "absent". Therefore, when set to the "partial release" side, only input from a specific security sensor is monitored. This is used, for example, in the summer when a person wants to go to bed with only the window on the second floor open, and the input from the sensor attached to that window is not monitored.

In the above configuration, when the mode is switched from release to alert, for example, when the mode changeover switch 21 is switched from "occupied" to "absent", the control unit 5
executes the processing operations shown in FIG. 3 regarding the input from the security sensor.

That is, in FIG. 3, when absentee switching is confirmed in step 100, the control section 5 starts a preset timer in step 101, and
If the security sensor is activated in step 102, it is checked in step 103 whether or not the timer time has expired, and if it has not expired, a flashing signal is sent to the lamp on the security display board 23 in step 106. , and waits for the timer time to expire while monitoring the sensor. If the timer time expires while the sensor continues to operate, the lamp is turned on in step 104, and subsequently, in step 105, an alarm is issued to the receiving device.
If the timer time expires in step 107 without the sensor operating, the lamp will not flash or the alarm will be activated, and even if the sensor is activated and the lamp flashes, the timer time will continue. If the operation is completed, the alarm operation will not be performed. In this embodiment, the timer time can be selected in advance from 1 minute to 3 minutes using a manual operator. Therefore, the operator can close the final exit and go out during this 1 to 3 minute period. In addition, if the security display board 25 flashes when you lock all the doors, including the final exit, and then change to indicate that you are not in the room, it means that one of the windows, etc. is open, so you can switch to indicate that you are in the room. Afterwards, you can completely lock the door and go out. After the above timer time expires, the state shifts to the normal monitoring state.

The same goes for the remote control unit 13, and when you close the last exit when going out, insert the key into the keyhole of the mode changeover switch 41 as shown in Figure 4, and turn it to the right to switch to alert mode, and the door is not fully locked. If so, the lamp LM will light up and you will know this.
You can check again after returning to release mode. Of course, no notification is sent to the receiving device during this time. The same applies to the case of "nighttime" switching.

In addition, in the above-mentioned embodiment, the blinking of the lamp was used as an alarm when an attempt was made to go out with the door incompletely locked, but the present invention is not limited to this, and other alarm means, such as Of course, an alarm sound or the like may also be used.

Further, in the above-described embodiment, it goes without saying that in response to input from a sensor other than the security sensor, such as a fire sensor, the alarm operation is performed regardless of the alarm/cancellation mode.

〔Effect of the invention〕

As explained above, according to the present invention, for a certain period of time after switching to alert mode, if there is an input indicating an abnormality from a sensor etc., an alarm is issued to notify the operator, and the receiving device By not issuing alarms, it is possible to effectively prevent false alarms on security information at the final exit, and it is also possible to easily check whether the door is completely locked when going out or sleeping. .
