As shown in Publication No. 51, a monitoring station and a monitored station that receives signals from sensors attached to equipment installed in a building are connected via a general subscriber line.

In this remote monitoring device, when a sensor attached to the equipment detects an abnormality in the equipment, a signal indicating the abnormality in the equipment is transmitted as a data signal from the monitored station to the monitoring station via a general subscriber line.

The monitoring station that receives this data signal contacts the office to dispatch a worker to the building where the monitored station is installed to investigate abnormal conditions in the equipment.

[Problem to be solved by the invention]

By the way, in the above-mentioned conventional remote monitoring device, when the data signal sent from the monitored station to the monitoring station is not received properly due to a failure on the branch station side, the monitored station reports to the monitoring station again after a time interval. However, data from the monitored station will not be received until the monitoring station repairs the problem, delaying the investigation of the equipment that caused the abnormality, and potentially causing great damage to the building where the monitored station is installed.

An object of the present invention is to solve the problems of the prior art described above.

To provide a remote monitoring device that can notify another contact point when an abnormality occurs on the side of a monitoring station and enables prompt dispatch of workers.

[Means to solve the problem]

In order to achieve the above objects, the present invention provides a remote monitoring device that converts the status of equipment of a monitored station into a data signal and transmits this data signal to a monitoring station via a telephone line. The apparatus includes a detection unit that determines whether or not the data has been transmitted normally, and transmits the data signal to a monitoring station, and when the detection unit determines that the data signal is abnormal, converts the content of the data signal into the content of an audio signal. The present invention is characterized in that means is provided for transmitting this audio signal to a telephone set at a business office corresponding to the monitoring station.

[Effect]

When communication between the monitoring station and the monitored station fails, the monitored device detects this abnormality, changes the notification destination from the monitoring station to the telephone at the office where the worker is, and re-dials. Furthermore, the notification signal is switched from a data signal to a voice signal, and the worker at the office is notified of an abnormality in the equipment on behalf of the monitoring station.

〔Example〕

Hereinafter, the present invention will be explained based on illustrated embodiments. Here, FIG. 1 is a block diagram of a remote monitoring device according to an embodiment of the present invention.

In the figure, 1 is the monitoring station, 2 is the building, 3 is the monitored station installed in the building 1, and 5 is the monitoring station 1, the office 4, and the monitored station 3.

Next, the operation of the embodiment will be explained. Equipment 7 in building 2
When an abnormality occurs, the sensor 6 informs the control section 19. The control section 19 first operates the network control circuit 12 and the telephone number switching section 11, connects the telephone number storage section 8 in which the telephone number of the monitoring station is stored and the dialing section 10, and then dials the monitoring station. Do this. When the monitoring station 1 is in a normal state, the line between the monitoring station 1 and the monitored station 3 is connected. Next, the control unit 19 operates the signal switching unit 17 to connect the modem 14 and the network control circuit 12, and further sends the management number and equipment information of the building 2 stored in the data storage unit 13 to the modem 14. The data signal is sent to the monitoring station 1 via the general subscriber line, and this signal is sent to the monitoring station 1 as a data signal.
The notification from the monitored station 3 ends when it is received normally.

On the other hand, an abnormality occurs in the monitoring station 1 when the monitored station 3 makes a dial call or sends a data signal to the monitoring station 1.
Therefore, when data signals between the monitoring station 1 and the monitored station 3 are not transmitted normally, the abnormality detection section 18 detects a communication abnormality and notifies the control section 19 of the abnormality. The control unit 19 receives the signal from the abnormality detection unit 18 and operates the telephone number switching unit 11 to change the telephone number of the reporting destination to the f′11 call number of the office 4 stored in the telephone number storage unit 9. Then dial again.
