Description

Description: TECHNICAL FIELD The present invention relates to a building remote monitoring device for monitoring equipment in a building from a distance.

[Prior Art] A conventional building remote monitoring device is disclosed in, for example, Japanese Patent Application Laid-Open No. Sho 59-108192.
As described in the official gazette, using a general subscriber telephone line, etc.,
A method of reporting an abnormal signal such as a failure of equipment or a fire or an intrusion of a thief to a service company such as a distant security company or a facility maintenance company is adopted.

[Problem to be Solved by the Invention] Since the conventional building remote monitoring device is configured as described above, the inspection and repair of equipment and the maintenance such as replacement work are included in the abnormal signal transmitted from the monitored station. When doing work,
There is a disadvantage that an erroneous abnormal signal due to an on / off operation of a power switch, a detection switch, or the like is included and transmitted.

To prevent this, an alarm prohibition switch is provided in the monitored station, and during inspection and maintenance, the operator turns on the alarm prohibition switch so that even if an abnormal signal occurs, the alarm is not transmitted to the monitoring station. However, if the user forgets to return the alarm prohibition switch, even if an actual abnormal signal is generated, the alarm cannot be issued to the monitoring station, which causes a problem that the building user is greatly troubled.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a building remote monitoring device that solves the above-mentioned problems of the related art and can prevent forgetting to return the alarm prohibition switch.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a method for processing abnormalities by using a monitored station that reports an abnormality of equipment and information transmitted from the monitored station via a communication line. A monitoring station that performs monitoring and a notification prohibition switch provided at the monitored station and prohibiting information transmission to the monitoring station, the state of the notification prohibition switch being transmitted to the monitoring station. An output means for outputting to the monitored station; a storage means for storing a state of the alarm inhibition switch; and a monitoring means for outputting an alarm signal when the alarm inhibition state of the alarm inhibition switch has elapsed for a predetermined time. Are provided in the monitoring station.

[Operation] When the alarm prohibition state stored in the storage device does not release the alarm prohibition even after the lapse of a predetermined time, an alarm signal is output from the monitoring means, whereby the operator of the monitoring station constantly monitors. A display is displayed on the display device indicating that the notification prohibition has not been released. Therefore, the operator informs the worker who performs the maintenance of the building that he has forgotten to return the alarm prohibition switch, and releases the alarm prohibition switch. As a result, it is possible to prevent an abnormal situation in which even if an actual abnormal signal is transmitted, the monitoring station cannot be notified.

Embodiment An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a block diagram showing the overall configuration of one embodiment of the present invention. A monitoring station 1 installed in a service company or the like, and monitored stations 2-1 to 2-n installed in a building or the like to be monitored.
Are communicated by the communication circuit 3.

The monitoring station 1 includes a central processing unit 11 that performs command processing and failure processing for the monitored stations 2-1 to 2-n, and a monitored station 2-1.
Communication device 12 for performing data communication with .about.2-n, display device 1
3. It consists of a recovery time monitoring device 14 and a storage device 15. The recovery time monitoring device 14 includes a counter 14a and a comparator 14b for comparing a predetermined value with the count value of the counter 14a.

The monitored stations 2-1 to 2-n include a sensor 24 for monitoring equipment and a change detection device for detecting an abnormal signal from the sensor 24.
21, a communication device 23 for transmitting an abnormal signal to the monitoring station 1, an alarm prohibition switch 25, and an alarm prohibition detecting device 22.

The alarm prohibition detection device 22 detects the state of the alarm prohibition switch 25, and issues a notification prohibition setting or release to the monitoring station 1 via the communication device 23 when the switch changes from off to on or from on to off. When the alert prohibition switch 25 is turned on, the change detection device 21 stops its operation and cannot detect an abnormal signal.

Next, the operation of the present invention will be described. Monitored station 2-
In order to carry out maintenance work in step 1, the operator must be
When 25 is turned on, the alarm prohibition detecting device 22 operates to stop the operation of the change detecting device 21, and notifies the monitoring station 1 via the communication device 23 that the alarm has been disabled. Monitoring station 1
Receives this alert via the communication device 12 and sends it to the central processing unit.
11 stores the information of the “state of the alarm prohibition device” in the storage device 15 and the counter 14a of the recovery time monitoring device 14.
Start. As a result, the counter 14a starts counting and sequentially outputs the count value to the comparator 14b.
4b compares a preset value with a value output from the counter 14a.

The worker at the monitored station 2-1 is notified that the alert is prohibited switch 25.
Is forgotten, the information of the alert prohibition state stored in the storage device 15 does not change, and the count of the counter 14a is advanced. Then, when the count value exceeds the set value, a signal is output from the comparator 14b. The central processing unit 11 outputs this signal to the display device
13 indicates that the alert prohibition switch 25 has been forgotten to be returned. The operator looks at this display and sees the monitored station 2-1.
Contact the sales office in charge of the maintenance and release it.
Therefore, when the sensor 24 operates and an abnormal signal is actually generated, it is possible to notify the monitoring station 1 without any trouble.

When the worker in the monitored station 2-1 has taken the correct process of returning the alarm prohibition switch 25 after the work is completed, the alarm prohibition detection device 22 sets the change detection device 21 to an operable state. On the other hand, the alarm prohibition detecting device 23 outputs an alarm prohibition canceling signal.
The data is input to the monitoring station 1 via the communication line 3 and the communication device 12. As a result, the central processing unit 11 sets the information of the “prohibition of alarm generation” stored in the storage device 15 as the information of the “release of alarm prohibition”. Then, the counter 14a of the recovery time monitoring device 14 is reset. For this reason, alarm prohibition switch 2
The counter 14a that has been operating when 5 is turned on returns to the initial state, and the output of the count value is stopped.

[Effects of the Invention] As described above, according to the present invention, an alarm signal is output when the alarm prohibition switch is in the alarm prohibition state for a predetermined time, so that it is possible to prevent forgetting to return the alarm prohibition switch. As a result, an abnormal signal from the monitored station can be issued to the monitoring station without any trouble.
