FIG. 2 and FIG. 3 are explanatory diagrams showing this type of conventional emergency reporting device. FIG. 2 is a block diagram showing a state where the emergency reporting device is connected via a telephone line, and FIG. FIG. 2 is a block diagram showing the configuration of the device.

In general, the building 10 shown in FIG. 2 is connected to detectors 11a to 11n for detecting an abnormality of equipment such as a water supply facility and a heating and cooling device (not shown) in the building 10, and the respective detectors 11a to 11n. An emergency reporting device 12, a telephone 13 attached to the emergency reporting device 12, and a switch 15 for selectively connecting one of the emergency reporting device 12 and the telephone 13 to a telephone line 14 are provided. Have been. Further, a monitoring center 16 for monitoring the above-mentioned equipment via a telephone line 14 has a receiving device 17 for receiving the above-mentioned notification, a telephone 18 attached to the receiving device 17, and And a switch 19 for selectively connecting one of the telephones 18 to the telephone line 14.

Conventionally, the above-mentioned emergency notification device 12 has, as shown in FIG.
A monitoring circuit 21 connected to the detectors 11a to 11n, a timed circuit 22 that emits a timed signal for a predetermined time, for example, every 24 hours, and a detection signal received by the monitoring circuit 21 and a timed signal emitted from the timed circuit 22. A central processing circuit 23 that performs arithmetic processing and outputs a command, and automatically dials the receiving device 17 via the telephone line 14 based on the command output from the central processing circuit 23, and is returned from the receiving device 17. And a modulation / demodulation circuit 25 that modulates / demodulates transmission information output from the central processing unit 23 into a form that can be transmitted via the telephone line 14 and outputs the information to the line control circuit 24. doing.

In this conventional emergency reporting device 12, for example, when the detector 11a detects an abnormality that has occurred in the equipment of the building 10, the central processing circuit 23 performs an arithmetic process on the detection signal received by the monitoring circuit 21 and issues a command. The line control circuit 24 automatically dials the receiving device 17 via the telephone line 14. And the receiving device
When the line control circuit 24 detects the response signal returned from the communication control circuit 17, the central processing circuit 23 outputs the transmission information, performs modulation / demodulation processing by the modulation / demodulation circuit 25, and then switches the transmission information.
15. Transmitted to the receiving device 17 via the telephone line 14 and the switch 19 in order. In this way, the emergency reporting device 12 sends an emergency report to the receiving device 17, so that the person monitoring the facility devices does not need to be resident in the building 10 itself, and the facility devices are transmitted via the telephone line 14. It can monitor and promptly respond to the occurrence of abnormalities in equipment.

Similarly, when a time signal is issued from the time circuit 22 at a predetermined time, the emergency notification device 12
A regular report is sent to 17. This allows the monitoring center 16 to know whether the emergency notification device 12 is operating normally, that is, to periodically check the operation state of the emergency notification device 12.

Then, the conventional emergency notification device 12 configured as described above
In the case of performing maintenance and inspection of equipment in the building 10, the switch 13 is operated to switch the information transmission path with the telephone line 14 from the emergency notification device 12 to the telephone 13; or By operating the power switch (not shown) of the emergency notification device 12 to turn off and on the power, even if any of the detectors 11a to 11n operates during the maintenance inspection of the equipment, the reception device from the emergency notification device 12 It is designed to prevent emergency calls to 17.

[Problems to be Solved by the Invention] By the way, in the conventional emergency notification device 12 described above, since the switch 13 is switched from the emergency notification device 12 side to the telephone 13 side, the timed circuit 22 Despite the issuance of the alarm, the emergency notification device 12 cannot perform the periodic notification, or the operation time of the timed circuit 22 is shifted due to the power on and off of the emergency notification device 12, so the periodic notification is delayed. Sometimes. In such a case, since the regular notification is not received by the receiving device 17 at a predetermined time, there has been a problem that the monitoring center 16 erroneously determines that the emergency notification device 12 has failed.

The present invention has been made in view of such a situation in the prior art, and its purpose is to eliminate the need to switch the information transmission path to the telephone line or to turn off or turn off the power of the emergency notification device itself. It is another object of the present invention to provide an emergency notification device that can prevent an emergency notification generated in response to a detection signal even when a detector is activated during maintenance and inspection of equipment.

Means for Solving the Problems In order to achieve this object, the present invention issues an emergency report in accordance with a detection signal output from a detector that detects an abnormality of equipment in a building, and is predetermined. An information output device carried by a maintenance person, comprising: a central processing circuit that issues a periodic report every time; and a line control circuit that transmits the emergency report and the periodic report via a telephone line. An output unit is connectable, and an input unit for inputting information output from the information output device to the central processing unit, and the central processing unit, based on the information input via the input unit It is configured to have a blocking unit for blocking emergency reports.

[Operation] Since the present invention is configured as described above, during maintenance and inspection,
When the information input device carried by the maintenance person is connected to the input unit, and the information of the information output device is input to the central processing unit via the input unit, the blocking unit of the central processing unit operates based on the information. Emergency calls are blocked. This allows
It does not require switching the information transmission path to the telephone line or turning off or turning off the emergency reporting device itself, and emits a signal in response to the detection signal even if the detector is activated during maintenance of the equipment. Emergency calls can be prevented.

Note that the blocking section does not normally operate because the information output device is not connected to the input section, that is, the central processing circuit issues an emergency report in accordance with the detection signal output from the detector. ing.

[Embodiment] Hereinafter, an embodiment of the emergency notification device of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the emergency notification device of the present invention. In FIG. 1, the same components as those shown in FIGS. 2 and 3 are denoted by the same reference numerals. That is, 11a to 11n are detectors, 13 is a telephone, 14
Is a telephone line, and 15 is a switch.

The emergency notification device 1 of the present embodiment shown in FIG. 1 includes a monitoring circuit 2 connected to the detectors 11a to 11n and a predetermined time, for example, every 24 hours, similarly to the conventional emergency notification device 12 described above. A central processing circuit 4 for processing the detection signal received by the monitoring circuit 2 and the time signal generated by the time circuit 3 to output a command, and a central processing circuit 4 2 via the telephone line 14 based on the output command.
A line control circuit 5 for automatically dialing and a response signal returned from the receiving device 17;
And a modulation / demodulation circuit 6 for modulating and demodulating transmission information output from the telephone line 14 into a form that can be transmitted via the telephone line 14 and outputting the information to the line control circuit 4.

The emergency report device 1 of the present embodiment is carried by a maintenance person and can be connected to an information output device 7 that outputs information on changes in monitors and monitoring conditions.
And an input unit 8 for inputting information output from the information output device 7 to the central processing unit 4. The central processing unit 4 supplies specific data to a specific address based on the information input through the input unit 8. Is provided to prevent the emergency report.

In this embodiment, when the information output device 7 is not connected to the input unit 8, that is, when the information output device 7 is in a normal monitoring state, similarly to the case of the emergency notification device 12 described above, the detector is used.
When a detection signal is output from any of 11a to 11n, the central processing circuit 3 processes the detection signal received by the monitoring circuit 2 to issue a command, and the circuit control circuit 5 issues a second command via the telephone line 14 by the circuit control circuit 5. Automatically dial the receiving device 17 shown in the figure. Next, when the line control circuit 5 detects the response signal returned from the receiving device 17, the central processing circuit 4 outputs the transmission information, performs the modulation / demodulation processing by the modulation / demodulation circuit 6, and then switches the transmission information to the switch 15 Is transmitted to the receiving device 17 via the telephone line 14, that is, an emergency report is sent to the monitoring center 16 in FIG. When a time signal is issued from the time circuit 3,
The time processing signal is processed by the central processing circuit 4 to issue a command, and a regular notification is made in the same manner as in the case of the emergency notification.

At the time of maintenance and inspection of the equipment, the information output device 7 carried by the maintenance person is connected to the input unit 8.
When the information is input to the central processing unit 4 via the CPU, the specific data is written to the specific address by the blocking unit 9 of the central processing unit 4, so that the blocking unit 9 detects any of the detectors 11a to 11n. Prevents emergency calls that are issued in response to a signal. On the other hand, when the timed circuit 22 outputs a timed signal, the central processing unit 4 emits timed information.

In the embodiment configured as above, the information transmission path to the telephone line 14 is switched by the switch 15 or the power of the emergency notification device 12 itself is not required to be turned on or off. Even if the detectors 11a to 11n operate at the same time, it is possible to prevent the emergency notification issued in response to the detection signal.

In this embodiment, the information output device 7 is connected to the input unit 8, and the information is transmitted to the central processing circuit 4 via the input unit 8.
By inputting, an emergency report is prevented even if an abnormality occurs in any of the equipment, but some equipment does not have the same state during maintenance and inspection, If there is an important thing that requires an emergency report even if an abnormality occurs during maintenance inspection, the emergency report is selectively blocked by a detection signal output from any of the detectors 11a to 11n, for example, from a predetermined detector 11a. The same effect as in the above embodiment can be obtained even when the emergency notification is performed only when the detection signal is output and the emergency notification is prevented when the detection signal is output from the detectors 11b to 11n. Can be obtained.

[Effect of the Invention] Since the present invention is configured as described above, it is not necessary to switch the information transmission path to the telephone line or to turn off or turn off the power of the emergency notification device itself. Even if the detector is activated during the operation, it is possible to prevent the emergency notification issued in response to the detection signal. Therefore, even though the timed circuit has issued a timed signal, there is no timed notification from the emergency notification device, and timed operation of the timed circuit does not delay the timed notification, that is, The periodic notification can be reliably performed at predetermined time intervals, and the monitoring center can be prevented from erroneously determining that a failure has occurred in the emergency notification device.
