Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to remote building management for managing office buildings, factory facilities, etc. (hereinafter collectively referred to as buildings) located in remote locations. Regarding the system.

[Conventional technology] Conventional building management involves controlling or monitoring various facilities such as environment, hygiene, and disaster prevention for each individual facility. A building comprehensive management system that comprehensively manages the building as a whole is provided by the applicant. This system uses a distributed control device that divides the various facilities in the building into one group for each room, and controls and system processing that spans multiple distributed control devices. The system is constructed by connecting the main control equipment that performs the operations with the operator control unit located at the Hill management center via a communication network, and improves system reliability and processing capacity by decentralizing management functions. It has the advantage of realizing efficient comprehensive management.

Further, as an extension of the above-mentioned building management system, a building group management system has also been developed that can collectively manage a plurality of distributed buildings at one location, that is, a central building.

This greatly contributes to the reduction of

[Problems to be Solved by the Invention] However, in conventional building management systems, when a monitoring device in a remote building detects an abnormality, a monitor or operator in the center building cannot detect the content of the abnormality in the building. After that, in order to stop and restart the abnormal signal sent from the building monitoring device, it is necessary to go to the remote building and reset the monitoring device in the remote building, especially if the remote building is spread over a wide area. In some cases, there is a problem in that it is practically impossible to perform a restart operation quickly.

[Means for solving the problems] The present invention has been made in view of the above problems, and
After detecting an abnormality in a remote building in the building management system as described above, the operator does not have to go to the remote building, so even if the remote buildings are widely distributed, the building monitoring system can be operated from the central building. The purpose is to enable easy restart.

Therefore, the present invention provides a communication line between a central management device that manages a building installed in a remote location, a building monitoring device located in the remote building, and a communication line between the central management device and the building monitoring bag. The central management device monitors the status of the building monitoring device connected to the communication line, and when an abnormality is detected, the central management device controls the building monitoring device via the communication control device. It is configured to output a restart command for resetting.

A reset line 56 is provided which connects to a peripheral input such as an RT or a printer. As will be described later, this reset line 56 is connected to the 5DU51 of the building monitoring device when any abnormality is detected in the remote building.
A signal for resetting peripheral devices such as a CRT and the like is output.

Next, the communication control operation by the GWS 13 will be explained with reference to FIG.

First, the MCU 33 of the central management device 10
A command is sent to the terminal to check for malfunctions such as disconnections. Upon receiving this check command, GWS I 3 checks the line status and replies with the result.

Next, MMU25, MCU33 or DCU on the center side
When there is a call request from 34 to the remote building side, GWS
13 determines whether the called destination (destination) 5DU51 is already connected, and if it is connected, the adapter 1
4 and the destination 5D from the center side via the public line 12.
It sends data and other signals to U51, and if it is not connected, it executes the dial amplifier, which dials the destination's phone number, and when it is connected to the destination, it performs the above transmission, and if it is not connected, it notifies the center side. Notice.

When the transmission ends, the GWS 13 resets the internal timer. From the perspective of preventing wasteful use of telephone lines, this timer is set for a certain period of time (
For example, a predetermined period of time is counted in order to disconnect the line if no transmission or reception is performed even after 80 seconds have elapsed.

On the other hand, when there is a call request from the 5DU 51 in the remote building to the center side, the GWS 1 3 determines whether or not the communication is to itself, and if "NO", the operation ends. ”Yes
”, the signal is received from the remote side via the public line 12 and sent to the destination MMU 25, MCU 33 or DCU.
34, and when this is finished, reset the above timer. Therefore, the timer is reset every time transmission and reception are performed between the center side and the remote side.

On the other hand, when the above-mentioned timer counts up for a certain period of time, that is, when the above-mentioned period of time has elapsed without further transmission/reception after the line is connected or transmission/reception is completed, the GWS will not connect. Turn off the line that is connected to
Stop the timer.

The GWS 13 performs one or more operations to control the center side MMU 25. MCU33 or DCU34 and 5DU51 on the remote building side. It controls communication with

On the other hand, on the remote building side, if there is data to be sent to the center, a communication operation using the 5DU 51 is performed. Referring to FIG. 6, first, the 5DU 51 determines whether the destination center station number is already connected. As a result, if it is connected, the 5DtJ51 sends a message to the center via the adapter 14 and public line 12,
Or receive a signal sent from the center side. On the other hand, if the center station is not connected, dial-up,
That is, the operation of dialing the telephone number of the destination is executed, and when the destination is connected, transmission and reception is performed between the center side and the remote side, and if the connection is not established, the process returns to the beginning.

When the above transmission is completed, the 5DU 51 resets the timer. This timer also measures a certain period of time in order to disconnect the line from the 5DU 51 when the above-mentioned communication is not performed, and is reset every time transmission and reception are performed between the center side and the remote side. Therefore, when this timer counts up a certain period of time, one line is cut off, the timer is stopped, and the operation ends.

By the way, if there is any abnormality in the various equipment in the remote building where it is located, the 5DU5L sends an abnormality detection signal to the central management device 10 via the GWS 13 to notify the abnormality. In the center building, after the supervisor checks the details of the abnormality, the GWS l is sent from the central management device 10.
3, a predetermined restart command is sent.

In the remote building, the processor 46 of the personal computer adapter 14 outputs a reset signal in response to this lift command. That is, as shown in the flowchart of FIG. 7, the processor 46 determines whether the received signal is a predetermined reset command or not, and if "Yes", the processor 46 determines whether or not the received signal is a predetermined reset command, and if "Yes", the peripheral devices such as the 5DU 51 and CRT connected to the personal computer adapter 14 are activated. A signal for resetting is output to the reset line 56. This allows the building monitoring device 11 that has detected an abnormality to return to its normal operating state.

Although the embodiment shown in FIG. 1 has been described above, the wooden invention is not limited to this.

For example, although the above embodiment uses a public line as the communication line, the present invention may also use a dedicated line. In that case, as shown in FIG. A dedicated line gateway (Gate Way) is a communication control device interposed between the dedicated line 15 and the
A Leased' 1ine (hereinafter referred to as GWL) 16 and an intelligent modem (modulator/demodulator) 17 having an information processing function using a processor are provided. and,
