Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring center device of a remote monitoring device for monitoring a plurality of terminal devices via a telephone line.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Patent Application Laid-Open No. 60-198422, when an abnormality occurs in equipment equipment installed in a building, an abnormality signal is issued from a terminal device on the building side, and the equipment of the building is The information is sent to the monitoring center that monitors the equipment remotely. For the terminal devices installed in each building, the priority order of the abnormal signal notification destination is determined in advance, and the first
There is proposed a technique in which when the monitoring center having the above priority order cannot receive the data, the monitoring center of the alert destination is sequentially changed according to the priority order.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned conventional technique, an abnormal signal of equipment in a building is transmitted to a first monitoring center having a high priority of a predetermined priority for the terminal device via a communication line. If the communication device of the first monitoring center fails and the first monitoring center cannot receive the abnormal signal, the terminal device sends the abnormal signal to the second monitoring center having the next priority. However, if the output device that prints and displays the abnormal signal at the first monitoring center fails, that is, if the building name and the abnormal equipment are not output for the abnormal signal, the action for the abnormal signal is first. The abnormal signal cannot be transmitted to the second monitoring center because it is not carried out by the first monitoring center and is normally received by the communication device. For this reason, there is a possibility that the abnormal state of the equipment continues for a long time and causes a great deal of trouble to the customer.

An object of the present invention is to provide a monitoring center device of a remote monitoring device capable of reliably processing a signal transmitted by a terminal device.

[0005]

In order to achieve the above object, an abnormality signal of equipment in a building is input, and a plurality of pre-stored report destinations are selected in a predetermined priority order, A terminal device for transmitting to the communication line, a communication device for receiving the abnormal signal transmitted from the terminal device from the communication line, and an output for printing and displaying the abnormal signal received by the communication device on an output device. In a monitoring center device of a remote monitoring device comprising a plurality of monitoring centers having a signal processing device for outputting a command signal at a constant cycle, the presence or absence of the output command signal is detected, and an output signal is issued when there is no output. An output command signal detection circuit is provided, and the output means outputs that the incoming call of the communication device is impossible in response to the output signal.

[0006]

Since the present invention is configured as described above, the output command signal detection circuit provided in the monitoring center is periodically output from the signal processing device when an abnormality occurs in the signal processing device. When it is detected that the output command signal for printing and displaying on the output device is not output, the output signal is output to the output device, and the output device, for example, the printer or the display, outputs that the communication is abnormal. Thereby, the abnormality of the signal processing device can be confirmed quickly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a monitoring center device of a remote monitoring device of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and 2 is a flow chart showing a processing procedure.

In the figure, a monitoring center device 3 monitors an abnormal state of equipment (not shown) connected to the terminal devices 1a to 1n via a telephone line 2. The monitoring center receives the abnormal signal by the communication device 32, and when the communication device 32 receives the abnormal signal, the communication device 32 stores the abnormal signal in a storage device (not shown). The signal processing device 35 connected to the communication device 32 confirms the abnormal signal data of the storage device (not shown) in the communication device 32 at a predetermined cycle, and then the storage device (not shown).
If the abnormal signal data is stored in, the abnormal signal data is read in a predetermined procedure, for example, in the order of oldest data history, and signal processing is performed so that the abnormal signal data can be displayed on the data output display unit 34. It is output to the unit 34. The data output display unit 34 displays the building name and the equipment name corresponding to the abnormal signal. An output command detection circuit 33 that detects a signal generated in a predetermined cycle in which the signal processing device 35 confirms a storage device (not shown) of the communication device 32.
Outputs an output signal so that the data output display unit 34 and the data output printer 36 indicate that the incoming call from the terminal device to the communication device is impossible.

Next, the operation will be described with reference to the flowchart of FIG. In step S101, when the signal processing device 35 detects a signal generated in a predetermined cycle for checking the storage device (not shown) of the communication device 32 by the output command detection circuit 33, the switch 31 is turned on in step S102.
When an alarm signal is issued from the terminal device 1a in S103, the abnormal signal data is received by the communication device 32 and stored in the abnormal signal data storage device (not shown). In step S104, the signal processing device 35 stores the abnormal signal data in the storage device (Fig. The abnormal signal data in (not shown) is read out, signal processing is performed, and the building name and facility equipment name in which the abnormality has occurred are displayed on the data output display section 34.

Next, when the signal processing device 35 fails,
In step S101, the output command detection circuit 33 causes the signal processing device 3 to operate.
When it is detected from 5 that the signal generated in the predetermined cycle has disappeared, in step S105, the data output display unit 3
4 and the output signal to the data printer 36. This allows quick confirmation of an abnormality in the signal processing device.

[0012]

According to the present invention, when the output command signal detection circuit of the monitoring center detects an abnormality in the signal processing device, the printer, the display or the like outputs a communication abnormality, so that the signal processing device can be quickly operated. Abnormality can be confirmed.
