Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring device, and more particularly to a remote device that saves time and money involved in a test for periodically checking the state of a telephone line.

<Prior Art> For example, as disclosed in Japanese Patent Application Laid-Open No. 59-94199, the operating state of equipment installed in a building, the occurrence of a fire, the intrusion of a suspicious person, etc. are provided in a building. In recent years, a remote building management system that uses a general subscriber telephone line to notify a monitoring center of a security company or service company when an abnormality is monitored by a terminal device has been widely adopted in various buildings.

Adopting this remote building management system eliminates the need for a building manager, thus reducing labor costs.

On the other hand, in this remote building management system, at least the state of the telephone line must be able to secure an appropriate level value at which data can be exchanged between the monitored station and the monitoring station, and if the line cannot be selectively closed. Cannot reliably transmit data to the monitoring station. In such a case, even if an abnormality occurs in the building, the state cannot be inspected by the monitoring station.

A remote monitoring and control device for solving this problem has been proposed in Japanese Patent Application Laid-Open No. 61-121551. In the remote monitoring and control device according to this proposal, the monitoring station sends the monitored station
Control command data for scheduling control of building equipment is periodically transmitted, and the state of the subscriber telephone line is checked accordingly.

In this method, as the number of monitored stations increases, the load on the monitoring station increases and the storage capacity increases. Therefore, generally, the schedule control data corresponding to the installed environmental conditions is provided on the monitored station side. And performs control based on the schedule control data.

<Problem to be Solved by the Invention> In the remote monitoring control device according to the above-mentioned proposal, the monitoring station receives the notification of the abnormal state from the monitored station within the preset line state confirmation test period. May be.

In addition, since the maintenance work includes a report check operation as one of the function tests on the monitored station side, the monitoring station issues a maintenance work from the monitored station within the period of the line state check test cycle. Information may be received.

As described above, when the monitoring station receives the notification of the abnormal state from the monitored station and the notification during the maintenance work from the monitored station, it is confirmed that the function of the line state has been confirmed. Become.

Therefore, during the same line state confirmation test period, performing a line state confirmation test from the monitoring station to the monitored station that has performed the above-described alerting operation is a wasteful telephone charge. It is meaningless just to be able to. Further, when the number of monitored stations increases, the time required for the line state confirmation test increases, so it is desirable to omit unnecessary confirmation tests.

The present invention has been made in view of the current situation of such a remote monitoring device as described above, and an object of the present invention is to efficiently perform a line state confirmation test and reduce the processing response time of the confirmation test. It is another object of the present invention to provide a remote monitoring device capable of reducing telephone charges.

Based on information transmitted from the first monitoring device in response to the call, a remote monitoring device configured to perform a confirmation test of the line state of the telephone line; The first monitoring device detects an abnormal state of the equipment, or the first monitoring device is artificially given an alarm condition, thereby causing the first monitoring device to perform the first monitoring.
When an alarm is transmitted from the monitoring device to the second monitoring device, a storage unit for storing the alarm is sent to the first monitoring device that has performed the alarm operation based on the storage in the storage unit. On the other hand, control means for stopping the line state confirmation test from the second monitoring device until the next line state confirmation cycle,
The configuration is provided in the second monitoring device.

<Operation> In the present invention, a periodic call is made from the second monitoring device provided in the monitoring center to the first monitoring device provided in the building at every predetermined period, Based on the information transmitted from the first monitoring device in response to the call, a confirmation test of the line state of the telephone line is performed.

In this case, in the storage means of the second monitoring device, the first monitoring device stores a notification due to an abnormality in the equipment or a notification at the time of artificial maintenance work within the cycle period of the line state confirmation test. It is confirmed whether the transmission to the second monitoring device is stored. When the notification of the first monitoring device is stored in the storage unit, the control unit of the second monitoring device operates, and the notification from the second monitoring device is performed until the next line state confirmation cycle. The test of checking the line status for the first monitoring device that performed the above is stopped.

In this way, according to the present invention, the monitoring center monitors the equipment and the like of the building at the monitoring center in a state where the test time for checking the line state is shortened and the telephone charge is reduced.
