Abstract

PURPOSE:To reduce the corresponding work of the operator of a center device by limiting information transmission from the information transmitting device of a terminal to the center device based on an abnormal signal to occur when inspection work for a facility device is executed. CONSTITUTION:When the abnormal signal from the same facility mechanism occurs more than the prescribed number of times within prescribed time, detecting means 4-6 provided for a terminal 2 detect this. A setting means provided for the terminal 2 is actuated by the detection of these detecting means 4-6, and the information transmission by an information transmitting device 8 of the terminal 2 is limited under prescribed conditions. Since the information transmission by the information transmitting device 8 of the terminal 2 is limited in this manner, the number of the times of the sounding of an abnormal signal receiving buzzer in a center device 1 and the number of the times of printing to a printing form can be limited. Thus, the corresponding work of the operator of the center device can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a building remote monitoring device that remotely monitors equipment in a building.

[Conventional technology] In order to reduce building management costs, a terminal device is installed in the building without having a manager stationed in the building, and the building equipment is remotely controlled by a center device via this terminal device. The use of remote monitoring devices to monitor buildings is increasing.

This type of building remote monitoring device is known, for example, from Japanese Patent Application Laid-Open No. 62-25
As disclosed in Publication No. 1900, a terminal device is installed in a building, and this terminal device has a sensor that detects abnormalities in equipment installed in the building, and an automatic dialer when this sensor detects an abnormality. It is equipped with an alarm device. In addition, by receiving alarms from the alarm device of this terminal device, building equipment can be remotely monitored.
A center device is provided in which an operator is permanently stationed to take necessary actions.

In a conventional building remote monitoring device with such a configuration, the terminal devices of multiple buildings are centrally monitored by the center device, and the center device takes necessary measures in response to the alarm from the alarm device. Management of equipment in multiple buildings is performed.

[Problems to be Solved by the Invention] In the conventional building remote monitoring device described above, there is a problem to be solved in the operation of the center device during maintenance and inspection work of equipment. In other words, when performing an operation test to check the smoke detectors on the equipment monitored by the center device, such as smoke detectors on fire alarm boards that notify of the occurrence of a fire, each time the smoke detector is activated, the fire alarm will be activated. The panel sends an abnormal signal to the terminal equipment in the building indicating that a fire has occurred.

Therefore, when inspection work is carried out one after another on the smoke detectors that are usually installed in several dozen locations in a building, based on the abnormal signal of a fire outbreak that is input one after another from the self-fire alarm board,
The notification device of the terminal device successively reports the occurrence of an abnormality to the center device.

For this reason, the operator of the center device must perform abnormal signal reception processing such as pressing a button to stop the abnormal signal receiving buzzer and separating printed printer paper every time an alarm is issued by the alarm device. Ta.

The present invention was made in view of the current state of this type of building remote monitoring device as described above, and its purpose is to detect abnormality signals generated from the same equipment due to maintenance inspection work on the same equipment. An object of the present invention is to provide a building remote monitoring device that limits the issuing of alarms from an alarm device of a terminal device under predetermined conditions.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a sensor that detects an abnormality in equipment in a building, and an alarm device that automatically dials when this sensor detects an abnormality. In a building remote monitoring system, a building remote monitoring system is equipped with a terminal device that receives alarms from the terminal device, and is equipped with a center device where an operator is stationed to take necessary actions. The terminal device includes a detection means for detecting that a signal is generated more than a predetermined number of times within a predetermined time, and a setting means for restricting the alarm from the alarm device under a predetermined condition based on the detection by the detection means. is equipped with.

[Operation] In the present invention, when an abnormal signal from the same equipment is generated more than a predetermined number of times within a predetermined time, the detection means provided in the terminal device detects this.

The detection by the detection means activates the setting means provided in the terminal device, and the notification by the notification device of the terminal device is restricted under predetermined conditions.

In this way, the alarms of the alarm device of the terminal device are limited, so the number of ringings of the abnormal signal reception buzzer in the center device and the number of times of printing on printer paper are limited.

[Example] The following is a block diagram showing the configuration of an embodiment of the present invention.

This will be explained in detail using diagrams.

As shown in the figure, a terminal device 2 is installed in a building.

A self-fire alarm abnormality detector 4, an elevator abnormality detector 5, and an air conditioning equipment abnormality detector 6 as sensors are connected to the determiner 7 of the terminal device 2. Also.

In the terminal device 2, the input terminal of the alarm device 8 is connected to the IB power terminal of the determiner 7.

The output terminal of the alarm device 8 is connected to the general subscriber telephone line 3.
A center device 1 installed at a service company etc.
It is connected to the. The above-mentioned self-fire alarm abnormality detector 4. In the elevator abnormality detector 5, when an abnormal signal is issued from the air conditioning equipment abnormality detector 6, this abnormal signal is input to the judgment device 7, and the driving signal from the judgment device 7 is transmitted from the first alarm device 8 to the general subscriber telephone line. A single alarm signal is transmitted to the center device 1 via 3.

Further, the 1 determiner 7 is provided with a detection means and a setting means, and the detection means is a self-fire alarm abnormality detector 4. When an abnormality signal from the air conditioning equipment abnormality detector 6 is detected from the same detector twice or more consecutively in two minutes, the elevator abnormality detector 5
A detection signal is given to the setting means. Furthermore, the setting means is activated by this detection signal and limits the alarming operation of the alarming device 8 under predetermined conditions, for example, when the same abnormal signal is emitted from the same equipment twice or more consecutively in two minutes. In this case, the alarm device 8 is controlled so that the alarm signal is not transmitted to the center device 1.

The operation of an embodiment having such a configuration will be described below.

When an abnormal situation actually occurs in the equipment, for example, an accident occurs in an elevator, the elevator abnormality detector 5 detects this and an abnormality signal is inputted from the elevator abnormality detector 5 to the determiner 7. The detection means of the determiner 7 determines that this abnormal signal is a normal abnormal signal and that it is the same continuously for 2 minutes.
Since it is determined that the equipment is not in a state where an abnormal signal is emitted more than once, the alarm device 8 performs an automatic dialing operation based on the drive signal from the determiner 7, and transmits an alarm signal to the center device 1. be done.

This alarm signal causes the abnormal signal reception buzzer of the center equipment 1 installed at the service company to sound, and the operator of the center equipment 1 can identify the equipment in which the abnormal situation has occurred and the name of the building where the equipment is installed. You can know that. Therefore, a service worker from a service company goes to the building and performs elevator repair service.

However, when inspecting smoke detectors of the self-fire alarm abnormality detector 4 installed in a building, for example, when performing inspection work on multiple smoke detectors one after another, the abnormal signal from the self-fire alarm abnormality detector 4 The detection means of the 5 determiner 7 detects, for example, 2
It is detected that the same equipment is emitting the same equipment more than once in a row.

By this detection, a detection signal is emitted from the detection means and inputted to the setting means, and the setting means restricts the alarm operation of the alarm device 8 under predetermined conditions. The transmission of the alarm signal to the device 1 is limited to the first time.

Therefore, the operator of the center device 1, who has been notified in advance that the inspection work of the automatic fire alarm abnormality detector 4 in a predetermined building will start at that time, confirms that the abnormal signal reception buzzer is sounding and the printer is operating. By doing so, it is possible to check that the building remote monitoring device is operating normally. In this case, since the alarm device 8 is limited to one alarm, the operator of the center device 1 operates the button to stop the abnormal signal receiving buzzer and the printer paper cutter.

There is no need to repeat the process, the number of routine tasks is reduced, and the number of communications is reduced, which reduces communication costs for inspection work.

In addition, in the center device 1, since the number of alerts from multiple terminal devices 2 is reduced, the number of regular subscriber telephone calls with one terminal device 2, I! 3 hold times have been shortened.

It is possible to efficiently process notifications from a plurality of terminal devices 2.

In addition, in the embodiment, a configuration has been described in which the alarm device is restricted from issuing an alarm when an abnormal signal from the same equipment occurs twice or more consecutively within two minutes. However, the present invention is not limited to this, and may be configured to limit the alarm from the alarm device if an abnormal signal is generated from the same equipment three or more times in a row within five minutes, for example.

[Effects of the Invention] According to the present invention, alarms from terminal devices and alarms from devices to the center device based on abnormal signals generated during inspection work on equipment are restricted, so that the operator of the center device can take action. This reduces work and reduces communication costs during inspection work.
