(Industrial Application Field) Conventionally, in this type of multiple terminal mutual monitoring device, terminal devices installed in each of a plurality of residential units are interconnected using a coaxial cable line of a CATV system as a signal line. When an abnormal condition such as a fire or gas leak occurs, an alarm signal (alarm data) consisting of data representing the contents of the abnormal condition and an address indicating the dwelling unit where the occurrence occurred is transmitted to the terminal equipment of other dwelling units,
This alarm signal from the alarm dwelling unit is received by another terminal device,
By sounding an alarm buzzer and lighting an indicator light, an alarm is displayed indicating the dwelling unit where the abnormal condition has occurred and the details of the abnormal condition, thereby enabling mutual monitoring of the occurrence of the abnormal condition among the dwelling units installed with a plurality of terminal devices.

(Problems to be Solved by the Invention) However, in such a conventional mutual monitoring device for multiple terminals, when an alarm signal is received from another terminal device, the alarm buzzer sounds and the display is displayed. Since the alarm was only displayed by turning on a light, the unit in which the abnormal situation occurred could not know whether the abnormal situation was reported by other terminal devices or not, and for example, if all other units were absent. In such a case, even though assistance cannot be obtained from other residences, the resident is expected to report to outside organizations such as the police or fire department.On the other hand, in the case of a false alarm, The problem remained that recovery operations were unilaterally carried out in the unit where the alarm was issued, and that no countermeasures were taken for other units, as even if a warning was issued, it was unclear whether it was a false alarm or not.

(Means for Solving the Problems) The present invention has been made in view of such conventional problems, and allows the alarming dwelling unit to know whether the alarm has been confirmed by other dwelling units, and in the event of a malfunction, to notify other dwelling units. An object of the present invention is to provide a mutual monitoring device for a plurality of terminals that can easily identify false alarms in residential units.

In order to achieve this objective, the present invention connects terminal devices installed in a plurality of dwelling units with signal lines, and when a specific terminal device detects an abnormal state, an alarm signal is transmitted to other terminal devices. In a mutual monitoring device for a plurality of terminals that mutually monitor each other by displaying the terminal in which an abnormality has occurred and the contents of the abnormal state, the confirmation means sends a confirmation signal to each terminal device by operating a confirmation switch and a confirmation switch. , and confirmation terminal display means for receiving the confirmation signal and displaying the confirmation terminal, so that the notification terminal can see the status of notification confirmation by other terminals.

Furthermore, regarding false alarms, a recovery means for sending a recovery signal to other terminals by operating a recovery switch, and a false alarm display means for receiving recovery signals from other terminals and displaying malfunctions are provided.
This makes it possible to easily confirm whether or not the alarm is a false alarm on a terminal device other than the alarm issuing terminal.

is supplied with a detected address signal from the address detector 14, and the confirmation signal generator 11 specifies the address of the reporting terminal and supplies a confirmation signal to the transmission interface 7.

The configuration of the terminal unit 1A is exactly the same for the other terminal units 1B to 1N.

FIG. 2 is an explanatory diagram showing an example of the display panels of the terminal units 1A to 1N shown in FIG. 1, and takes as an example a case where six residential units are grouped into one group for mutual monitoring.

In Figure 2, 21A to 21F are housing unit indicators;
Specifically, an illuminated switch having a function as a confirmation switch is used, and when an alarm signal is received from another terminal unit, one of the corresponding dwelling unit indicators 21A to 21F lights up. Then, when any one of the dwelling unit indicators 21A to 21F consisting of illuminated switches is pressed, a confirmation signal is sent to the alarm terminal. In addition, occupancy indicators 22A to 22F are arranged next to the dwelling unit indicators 21A to 21F, which are composed of light switches, and when the confirmation switch is operated on another terminal unit after transmitting the alarm signal, the dwelling unit Any one of the room occupancy indicators 22A to 22F corresponding to the indicators 21A to 21F lights up.

Furthermore, status indicators 20a to 20c are installed at the bottom of the panel to display the contents of abnormal conditions such as fire, theft, and gas leak, and on the right side there are display units for self-detection of abnormalities or reception of alarm signals from other terminal units. An emergency indicator light 24 that is driven to display is provided.

In this embodiment, when an abnormal state is detected, the abnormality indicator light 24 and the status indicators 20a to 20a indicating the contents of the abnormal state are
20C lights up at the same time, but when an alarm signal is received from another terminal unit, first only the abnormality indicator light 24 lights up, and then a light switch indicates which alarm dwelling unit is lit. When a switch operation (confirmation operation) is performed to press any of the indicators 21A to 21F, one of the status indicators 20a to 20C lights up in response to the confirmation switch operation, indicating the content of the abnormal condition, ie, fire.

Begins to indicate theft or gas leak.

Furthermore, a recovery switch 12 is provided above the emergency display 24, and by pressing the recovery switch 12, the alarm display state is cleared, and when a self-alarm is issued, a recovery signal is sent to other terminal devices. I come to do it. Furthermore, a false alarm indicator 23 is provided in the upper right corner, and when a restoration signal is received after receiving an alarm signal from another terminal unit, the abnormality display is canceled based on the reception of the restoration signal, and the false alarm indicator 23
will light up.

Next, the operation of the above embodiment will be explained with reference to the flowcharts of FIGS. 3 and 4.

The flowchart in FIG. 3 is a flowchart showing an example of self-alarm processing, and in a normal monitoring state, the determination block 30 monitors whether or not an alarm has been triggered due to fire, theft, or gas leak detection. There is. In this state, when a detection signal is obtained from the sensor that detects the own abnormal state and it is determined that an alarm has been issued, the process proceeds to block 32, where the own alarm indicator light is turned on and the alarm buzzer 19 is sounded to detect the abnormality. notification and display the details of the alert. That is, it lights up the abnormality indicator light 24 on the monitoring panel of the terminal unit shown in FIG. 2, sounds an alarm buzzer, and lights up the dwelling unit indicator 21A when a self-alarm occurs in the terminal unit 1A, for example. Furthermore, one of the status indicators 20a to 20c is turned on to indicate whether there is a fire, theft, or a gas leak.

Next, the process proceeds to block 34, where a notification signal consisting of a data structure indicating an address and a notification status is sent to other dwelling units. As will be explained later, other terminal devices that receive the alarm signal sent by this block 34 will display an alarm for the alarming residence, so if you are home, you can confirm the alarm. The operation is performed and a confirmation signal is sent back.

Therefore, a determination block 36 checks whether a confirmation signal is received from another dwelling unit, and when a confirmation signal is received, the process proceeds to block 38 to display the dwelling unit in which the confirmation operation has been performed.

Furthermore, it is checked in the determination block 40 whether or not a restoration operation has been performed, and unless the restoration operation is performed, the processing of monitoring confirmation displays by other dwelling units in the determination blocks 36 and 38 is repeated.

On the other hand, if it is a false alarm, a recovery operation is performed, so the process proceeds to judgment block 42, where an alarm cancellation signal (recovery signal) is sent to other terminal devices, and at the same time, the own alarm is displayed in accordance with the recovery operation. A recovery operation is performed to cancel the error, and the process returns to the alarm monitoring process of determination block 30 again.

FIG. 4 is a flowchart showing an embodiment of the alarm receiving process in another terminal unit, and the determination block 50
At this point, it monitors whether or not an alarm signal is received from another terminal unit, and when an alarm signal is received, the process proceeds to a determination block 52, where it is determined whether it is an alarm signal or a recovery signal. . If it is a warning signal, the address and contents of the warning are determined from the warning signal in block 54, and the notification dwelling unit is displayed in block 56. Next, the determination block 58 monitors whether or not the confirmation switch has been operated, and if the confirmation operation is not performed, the state returns to the reception state of the determination block 50, and the process proceeds to block 5.
The display state of the notified dwelling unit as done in step 0 is maintained.

On the other hand, if the confirmation operation is performed, the process proceeds to block 60;
Until then, only the emergency indicator light 24 shown in Figure 2 was turned on when the alarm was received, but in conjunction with the confirmation operation, the status indicator 2
The content of the alert is displayed by lighting one of 0a to 20C, and at the same time, in block 62, a confirmation signal is sent to the alert terminal.

On the other hand, if the received signal of the determination block 52 is a recovery signal, the process proceeds to block 64, where the alarm display is restored, a false alarm is displayed, and the process returns to the reception monitoring state of the determination block 50 again.

As is clear from the self-alarm processing and alarm reception processing in each terminal unit shown in Figures 3 and 4, when the alarm signal is sent to other terminal units due to self-alarm If there is a person in the unit where the terminal unit is installed, the occupancy will be displayed after receiving a confirmation signal from the confirmation operation.
Whether or not the abnormal situation could be communicated to other dwelling units can be immediately known from the alarm terminal.

In addition, if an alarm is triggered due to a malfunction, the false alarm will be displayed on other terminal units as the recovery operation is performed, so there is no need to make any special contact and it is possible to confirm that the alarm was a false alarm in other units. This can be confirmed, and when other dwelling units receive the alarm signal, they do not have to know whether it is a false alarm or not and are not at a loss for countermeasures.

(Effects of the Invention) As described above, according to the present invention, terminal devices installed in a plurality of dwelling units are connected to each other by signal lines, and when a specific terminal device detects an abnormal state, an alarm signal is transmitted to another device. In a mutual sensing device for multiple terminals that mutually monitors each other by transmitting information to the terminal device and displaying the terminal in which an abnormality has occurred and the details of the abnormal state, a confirmation means for sending a confirmation signal to each terminal device by operating a confirmation switch. Since the system is equipped with a confirmation terminal display means that receives the confirmation signal and displays the confirmation terminal, this confirmation function allows the alarm terminal to check the status of alarm confirmation by other terminals, and prevent fires, theft, gas leaks, etc. Even if the resident unit is busy taking countermeasures when an abnormal situation occurs, it can be expected that other units will report to the police, fire department, etc., and quick response measures can be taken through mutual monitoring in the event of an emergency situation. You can take it.

In addition, each terminal device is equipped with a recovery means that sends out a recovery signal when the recovery switch is operated, and a false alarm display means that receives recovery signals from other terminals and displays malfunctions, so it can be restored in the event of a malfunction. If you perform this operation, a false alarm will be displayed in other dwelling units, so you can accurately grasp the situation of the alarming unit without hesitating to judge whether it is a false alarm or not. This greatly contributes to maintaining a sense of trust in mutual monitoring of multiple residential units.
