Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a building group management system that collectively manages a group of buildings using public subscriber telephone lines.

[Conventional technology]

If you own multiple buildings or are contracted by a building owner to manage a group of buildings, the building owner or building maintenance company will require the Ministry of Building Management.

As a measure to increase power, the adoption of a system that centrally manages buildings owned or managed is being considered.

Conventional building group management systems that collectively manage such owned or managed buildings include expanded building management systems and remote monitoring systems. The former type of expanded building management system has functions such as equipment status monitoring, start/stop control, and measurement/metering monitoring using expanded functions within the same system, and uses a dedicated line as a communication network. .

The latter remote monitoring system only performs status monitoring and abnormality monitoring (reception), and uses subscriber telephone lines as the communication network.

[Problem that the invention seeks to solve]

However, when group management is performed using an expanded version of the former building management system, extended functions within the same system are used, so when connecting with other systems, the data transmission methods are different, so mutual signals must be converted. A device (adapter) and its software development are required. Therefore, if the managed building is already installed and other systems are configured (
If this is the case (most of the time), the existing equipment must be replaced. Therefore, the cost of introducing the system becomes extremely high. Furthermore, since it is a multi-functional type, it lacks flexibility because it uses dedicated lines to configure the communication network.

On the other hand, when group management is performed using the latter remote monitoring system, there is no control function (transmission), so emergency measures (measures to save the least number of children) are delayed. In addition, in the center building (the building where the main equipment is installed), devices are required to monitor both the own building and the group of subsidiary buildings.

The present invention solves the above-mentioned problems, and aims to provide a building group management system that can flexibly accommodate existing buildings and buildings with different types of management devices.

[Means to solve the problem]

To this end, the building group management system of the present invention is a building group management system that connects a center building and a plurality of subsidiary building groups through subscriber telephone lines to monitor and control the building equipment, and each of the center building and a plurality of subsidiary building groups A control terminal that automatically sends/receives calls to a subscriber telephone line is installed in the terminal, and signals are transmitted between the control terminal and a device that monitors and controls equipment in the building using contact signals. .

[Effect]

In the building group management system of the present invention, a control terminal that automatically sends/receives calls to subscriber telephone lines is installed in each of the center building and the subsidiary buildings, and the control terminal is connected to a device that monitors and controls equipment in the building. Since signals are transmitted between the two using contact signals, it can be easily applied to existing buildings or buildings with different types of management equipment.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining one embodiment of the building group management system according to the present invention, and FIG. 2 is a diagram showing the configuration of one embodiment of the building group management system according to the present invention.

In FIG. 1, 1 is a group control terminal, 2 is a local control terminal, 3 is an interface section, 4 and 8 are terminal sections, 5 and 6 are communication control sections, and 7 is a relay part.

As shown in FIG. 1, the building group management communication control device according to the present invention is connected to a group control terminal 1 installed in a center building and the group control terminal 1 via subscriber telephone lines, and installed in each of the subsidiary buildings. The local control terminal 2 has a relay part 7 for processing the vJ1'B signal to the equipment of the subsidiary building group and the status signal of the equipment.

The group control terminal 1 automatically receives information sent from the sub-building group via the subscriber telephone line, identifies the sub-building and equipment from which the information is sent, monitors the status, and sends control signals to the sub-building group. do. The local control terminal 2 detects changes in the operating status (running/stopping) of equipment in the building and abnormal conditions from changes in contact signals from power control panels, monitoring panels, etc., and sends the information to the center building via the subscriber telephone line. The communication control unit 5.6, which automatically transmits status signals and receives and processes control signals from the center building, processes the transmission and reception of signals between the center building and the group of subsidiary buildings via subscriber telephone lines. It is something to do.

As shown in FIG. 1, in the building group management communication control device of the present invention, the control signal to the building equipment equipment to be managed at the end of the bundle is a contact signal, and the building management system of each manufacturer Focusing on the fact that the input/output signals of are contact signals,
The local control terminal 2, which is installed in each sub-building group and monitors and controls the equipment in that building, is equipped with a relay part, and the group control terminal 1 is equipped with an interface section 3 that can process contact signals. The transmission method is hand-to-hand.

Next, among the buildings, one building is connected as a center building and the other buildings as a group of subsidiary buildings are connected through independent communication networks using subscribed telephone lines, and the center building is used to operate the via equipment of the own building and the subsidiary buildings. An example of a system that performs management will be described.

In this system, a central monitoring device, a power control panel, a remote control panel, etc. are installed in a center building, a group of subsidiary buildings, and each building.

In Figure 2, 11 is Center Building, I2-1 to 12
-3 is a subsidiary building, 13 and 17 are power control panels, 14 is a remote station, 15 is a master console (central monitoring main device), and 16 is a switching network. The group control terminal 1 in the center building controls the operation of equipment in its own building and the group of subordinate buildings, and the master console (central monitoring main device) 15 centrally monitors its own building.

First, to explain the status monitoring of the subsidiary building group consisting of the subsidiary buildings 12-1 to 12-3, in the subsidiary building group, the local control terminal (LCT) 2 installed in each of the subsidiary buildings 12-1 to 12-3 is , changes in the operating status B (running/stopping) of equipment in the building and abnormal conditions are detected from changes in contact signals from control panels, monitoring panels, etc. The detected signal is transmitted to the communication control section (
communication controller) and automatically communicates with Center Building 1.
1.

At Center Building 11, the group control terminal (O
CT) 1 automatically receives information sent from the subsidiary building group. When the communication control unit (control center) of the group control terminal l receives the coded signal,
The subsidiary buildings 12-1 to 12-3 and equipment are identified and sent to the interface section (remote controller). The interface unit (remote controller) uses the signals to open and close the physically assigned contacts, thereby reproducing the remote status changes of the equipment in the sub-building.

The remote station or monitoring panel of the central monitoring device installed in the center building 11 is located in the subsidiary buildings 12-1 to 12-1.
2-3 detects changes in the status of the equipment, and indicates to the operator any changes in the status or abnormalities of the equipment in the building group through means such as displays or alarms.

Next, the start/stop control from the center building 11 to equipment in the subsidiary buildings will be explained. When a master console (central monitoring main device) 15 installed in the center building 11 issues a start/stop command to a designated device, the signal is sent as a contact signal from a remote station. This signal is received by the interface section (remote controller) of the group control terminal 1, and a transmission signal is sent to the communication control section (control center). The communication control unit (control center) identifies the relevant building, automatically dials the building in question, and transmits this information to the communication control unit (communication controller) in the local control terminal.

In the sub-building group that received the call, the call is automatically received at the local control terminal, the contact is opened and closed via a relay part for the corresponding equipment, the command from the center building is reproduced, and the power control panel and remote control panel are activated. etc.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since a contact-passing transmission method is adopted, inexpensive commercially available products (sequence programmer, device group, etc.) can be used, and there is no need to develop new devices and software. disappears. In addition, no matter what type of building management device you have, you can simply connect different systems through the device.
It becomes possible to combine independent and distant systems and operate them as if they were a building group management system constructed from the same system. Furthermore, building group management can be handled by carrying out the minimum necessary renovation work without having to renew the existing system.
Significant cost reductions can be expected.

The local control terminal that monitors and controls building equipment is equipped with a relay unit, which reduces the amount of modification required for managed equipment (power control panels) in subsidiary buildings. In other words, it can be handled simply by taking out the contacts, and there is no need to add relay panels, etc. This will lead to a reduction in renovation costs for existing subsidiary buildings.

Since subscriber telephone lines are used as the communication network, it is expected that communication costs for users will be reduced.
