Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a system in which a plurality of distributed control systems are installed at a lower level of a central monitoring panel that manages the entire building, controlling control systems for each floor or area of the building. The present invention relates to a distributed building management system.

[Prior Art] FIG. 5 shows the overall configuration of a conventional relatively large-scale building management system. Central monitoring panel C that manages the entire building
is connected to the upper network N2 via gateway A. This upper network N2 includes a plurality of distributed control systems BB 2 , B 3 , B
4, B s , B b , . . . are connected. Each distributed control system B + , B 2 , B
s , B 4 , B s , B s , ... correspond to the central monitoring panel in a small to medium-sized building management system, and are connected to the heat source panel, power substation panel, air conditioning control panel, and electric lights via the lower network N1. It is connected to various control panels such as distribution boards and disaster prevention panels, or to various terminal devices. Each control panel controls a large number of terminal devices via a dedicated transmission line using a time division multiplex transmission method or the like. The host computer serving as the central monitoring panel C connects to the distributed control system B via the upper network N2. B2, Bs, B4,
It transmits control data to Bs, B&, . . . and further transmits data to various control panels via the lower network N1. The terminal devices are controlled from each control panel.

As described above, in relatively large-scale building management systems, it is common to have a distributed system configuration with the above-mentioned hierarchical structure. A host computer, so-called a central monitoring board, is equipped with tables and the like so that it can manage information ranging from approximately 5,000 to several tens of thousands of points in terms of the number of end terminals. In addition, each distributed control system has a specialized receiver for each floor or area, receives management/control information from a central monitoring panel, and centrally manages its own floor or area. Each control panel group and terminal device group under this distributed control system will be collectively referred to as a floor-specific or area-specific control system group.

[Problems to be Solved by the Invention] Needless to say, the advantage of distributed control is that it reduces processing by the host computer and enables flexible control for each floor or area, but it is difficult to manage the entire building. In order to successfully coordinate management by floor or area, it is necessary to design a system according to the capabilities of the host computer that serves as the central monitoring board and the capabilities of the distributed control system. Workstations, minicomputers, personal computers, etc. installed in buildings for purposes such as OA (office automation) are located above the central monitoring panel and connected to the LAN.
However, if a computer terminal is installed on each floor or area and control is performed by floor or area from there, an excessive burden is placed on the host computer, and , the significance of the distributed control system itself becomes weaker. The basic problem is that the distributed control system does not include an input/output device for individual information for controlling each floor or area.

Furthermore, when inputting such individual information, the distributed control system must be able to make use of that individual information. In order to realize air conditioning and lighting control according to the needs of customers, with conventional methods, it was necessary to change the host computer that serves as the central monitoring panel.

The present invention has been made in view of these points, and its purpose is to provide an input/output means for individual information to the distributed control system in a distributed building management system using a hierarchically structured distributed control system. By adding, for example, air conditioning control according to personal information, air conditioning/lighting control according to personal schedule information, etc. can be realized, and flexible load control can be realized without increasing the burden on the central monitoring panel. be.

Here, as the individual information, for example, personal information for air conditioning control, personal schedule information for air conditioning/lighting control, etc. can be used.

[Function] In the distributed building management system of the present invention, as described above, input means and/or output means for individual information management, such as an IC card reader R, are added to the distributed control system B. Therefore, load control corresponding to individual information can be realized at the level of the distributed control system B without increasing the burden on the central monitoring board C.
