Abstract

PURPOSE:To promptly cope with a highly important supervising object by notifying a superviser of only the abnormality of the highly important supervising object when the abnormality occurs at the supervising object. CONSTITUTION:When the abnormality occurs in a building 10, and the abnormality is detected by sensors 14 and 18, it is regarded as the low-importance supervised object, and an alarm commanding signal is not outputted from a supervisory equipment 24. When the abnormality is detected by sensors 12 and 16 to detect the highly important supervised object, it is decided as the abnormality of the highly important supervised object by the supervisory equipment 24, and the alarm commanding signal is outputted. The alarm commanding signal is not only transferred from a line connecting device 32 to a monitor center 36 but also transmitted to a portable alarm display 38, and even when the superviser is out of the building, the superviser can be notified that the abnormality has occurred at the highly important supervised object in the building 10 if he brings the portable alarm indicator 38 with him.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote monitoring device, and particularly to a remote monitoring device suitable for monitoring abnormalities in a monitored object according to their importance.

[Conventional technology]

As a device for remotely monitoring abnormalities inside buildings,
For example, the one described in Japanese Unexamined Patent Publication No. 60-29899 is known. According to this device, even if an abnormality occurs in the building while the supervisor is absent, the alarm display device carried by the supervisor can be notified of the abnormality. Therefore, even if the supervisor is not in the building to be monitored, it is possible to deal with the occurrence of an abnormality.

[Problem that the invention seeks to solve]

In the above conventional technology, it is not determined whether or not to notify the monitor based on the importance of the alarm, and when an abnormality occurs in the monitored object, an alarm is not issued to the monitor regardless of the level of importance. Ta. When an alarm is issued, the monitor cannot distinguish whether the alarm is urgent or not, and there is a risk that response will be delayed if multiple monitoring targets become abnormal at the same time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a remote monitoring device that can notify a supervisor only of abnormalities in monitoring targets of high importance.

[Means for solving problems]

In order to achieve the above object, the present invention includes a group of sensors that each detect an abnormality in a plurality of monitoring targets, and an alarm command signal is generated by the detection output of a sensor that detects an abnormality in a highly important monitoring target among the sensor group. The remote monitoring device includes a transmitting means for transmitting data, and an alarm means for receiving an alarm command signal from the transmitting means and emitting an alarm.

[Effect]

When one of the plurality of monitoring targets becomes abnormal, a detection signal is output from a sensor that detects the abnormality of the monitoring target. If the sensor detects an abnormality of a monitoring target of high importance, an alarm command signal is output from the transmitting means based on the detection output of the sensor. When this alarm command signal is received by the alarm means, the alarm means issues an alarm, thereby informing the supervisor that an abnormality has occurred in the highly important monitoring target.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIG. 1.

In FIG. 1, a building 10 includes sensors 12, 14 . i6 and 18 are provided.

Among the sensors 12 to 18, the sensors 12 and 16 are sensors that detect an abnormality in a monitoring target of high importance, and are configured with sensors that detect a fire in the building 10 as a monitoring target. The sensor 14 is composed of a sensor that detects abnormalities in the pump as a monitoring target. Further, the sensor 18 includes a sensor that detects an abnormality in the water level of the water supply system.

The output signals of the sensors 12 to 18 are supplied to a monitoring device 24 via terminal devices 20 and 22, respectively.

The monitoring device 24 includes a storage unit 26 that stores data regarding the sensors 12 to 18 separately for sensors that detect abnormalities in monitoring targets of high importance and other sensors, and the sensor 1.
A determining unit 28 compares the output signals 2 to 18 with the contents of the storage unit 26 to determine whether or not the abnormality of the monitored target is of high importance; It is composed of an alarm command unit 30 that outputs an alarm command signal when it is determined that an abnormality has occurred.
An alarm command section 30 is connected to a line connection device 32.

The line connection device 32 is composed of a line selection unit that selects an arbitrary line from a plurality of lines, and a transmission unit that superimposes an alarm command signal on a high frequency signal and transmits it from an antenna.
A line selection section is connected to a monitoring sensor 36 via a telephone line 34. Further, the alarm command signal transmitted from the transmitter includes information for generating an alarm only on a specific alarm display. Therefore, when an alarm command signal is output from the transmitter, a display indicating that an abnormality has occurred in the monitored object is displayed on the portable alarm display 38 designated by the alarm command signal.

In the above configuration, when an abnormality occurs in the building 10 and this abnormality is detected by the sensors 14 and 18,
The monitoring device 24 will not output an alarm command signal as an abnormality of a monitoring target of low importance.

On the other hand, an abnormality occurs in building 10, and this abnormality causes sensor 1 to
2 or detected by the sensor 16, the monitoring bag w24 determines that the abnormality is a highly important monitoring target, and the monitoring bag M24 outputs an alarm command signal. This alarm command signal is transferred from the line connection device 32 to the monitoring center 36 and is also transmitted to the portable alarm display 38. Therefore, if the supervisor carries the portable alarm display device 38, even if the supervisor is outside the building 10, it is possible to notify that an abnormality has occurred in a highly important monitoring target within the building 10. Able to quickly respond to abnormal situations.

Furthermore, in the embodiment described above, the alarm command signal is transmitted from the antenna of the line connection device 32; however,
Instead of transmitting radio waves from the line connection device 32, it is also possible to have the monitoring center 36 transmit the alarm command signal as radio waves.

Further, in the embodiment, the sensors 12 and 16 and the sensor 1
If the outputs of the sensors 12 and 18 are connected to the monitoring device 24 through separate systems, and the alarm command signal is output based on the signals from the sensors 12 and 16, the storage section 262 and the determination section 28 become unnecessary.

〔Effect of the invention〕

As explained above, according to the present invention, when an abnormality occurs in a monitored target, only the abnormality in the monitored target with high importance is notified to the supervisor, so that the monitoring target with high importance and the low importance Even if the monitored targets become abnormal at the same time, the highly important monitored targets can be dealt with quickly.
