[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a building group management system, and more particularly, the present invention relates to a building group management system, and in particular, it uses at least one terminal device installed in each of a plurality of buildings to monitor equipment such as air conditioning and security equipment installed in the building, and to monitor the building maintenance. Receives security management signals,
The present invention relates to a building group management system that manages a building group by sending this management signal to a center device.

0002

[Background Art] At least one terminal device is installed in each of a plurality of buildings, and this terminal device receives signals from building maintenance and security equipment such as air conditioning equipment and security equipment of the building regarding their operating status and the occurrence of abnormal situations. Outputs an alarm signal indicating
A building group management system that manages the maintenance and security status of a building group by sending these signals from a terminal device to a center device via a communication line is well known these days.

[0003] In order to ensure proper functioning of such a building group management system, system inspection is essential.

[0004] The inspection work of the conventional building group management system is as follows:
This was done in such a way that maintenance personnel regularly visited each terminal device and received pseudo status/alarm signals input from the outside to the terminal device at the center device.

[0005]

Problems to be Solved by the Invention When performing system inspection work on a conventional building group management system, there was a problem in that maintenance personnel had to travel to the location where the terminal equipment was installed.

[0006] The purpose of the present invention is to solve the above-mentioned problems,
To provide a building group management system that allows maintenance personnel to inspect the system without moving to a terminal device.

[0007]

[Means for Solving the Problems] The building group management system of the present invention includes a center device connected to a communication line using a private line or a public line, and at least one central device installed in each of a plurality of buildings. a plurality of terminal devices that receive status signals indicating the operating status and alarm signals indicating the occurrence of an abnormal situation from monitored devices necessary for maintenance and security, and send these to the center device via the communication line; In a building group management system that manages a plurality of buildings, the center device sends an automatic inspection signal to the terminal device to check the operation of the system via the communication line,
The terminal device receives the automatic inspection signal, generates a simulated signal simulating the status signal and alarm signal, and sends it to the center device via the communication line, thereby automatically inspecting the system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

The embodiment shown in FIG. 1 includes a sensor device 1 connected to a communication line 2 that uses a dedicated line or a public line, and a status/alarm output from monitored equipment acquired in each building via the communication line 2. It is configured to include a plurality of terminal devices 3-1 to 3-n that output signals to the center device.

FIG. 2 is a block diagram showing the configuration of the terminal device shown in FIG.

The terminal device shown in FIG. 2 has a line interface 4 that interfaces with the communication line 2, and sends an automatic inspection signal 101 from the center device 1 input via the line interface 4 to a simulated signal generator 6. , the control unit 5 receives the status/alarm signal 801 output from the monitored equipment via the status/alarm input unit 7 and sends it to the line interface 4, and the automatic inspection signal 101 received from the control unit 5 generates the status/alarm signal. Simulated signal 601 that simulates 801
It includes a simulated signal generating section 6 that outputs and sends it to the status/alarm input section 7, and a status/alarm input section 7, and further shown in FIG.
Monitored equipment 8 such as air conditioning and security equipment is also shown.

Next, the operation of this embodiment will be explained.

From the center device 1 to the terminal devices 3-1 to 3-n
When performing automatic inspection, first, an automatic inspection signal 101 is transmitted from the center device 1 to the terminal devices 3-1 to 3-n via the communication line 2.

In the terminal devices 3-1 to 3-n that have received the automatic inspection signal 101 via the line interface 4, the control section 5 controls the simulated signal generation section 6 to input the status/alarm input section 7 as if it were an external signal. A simulated signal 601 that simulates the state/alarm signal 801 from the monitored device 8 as if it were input is output.

When the simulated signal 601 is input to the status/alarm input unit 7 , the control unit 5 receives this simulated status/alarm signal from the status/alarm input unit 7 and sends it to the center device 1 via the line interface 4 . Send to.

[0017] In this way, system inspection can be automatically performed.

[0018]

As explained above, the present invention generates a simulated signal of the status/alarm signal output by the monitored equipment in the terminal device using the automatic inspection signal sent from the center device.
By transmitting the information to the center device, maintenance personnel can perform inspection work on the terminal device at the location where the center device is installed, without having to travel to the location where the terminal device is installed.
