Abstract

The invention discloses a building intelligent auto-control system DDC (direct digital control) and an auto-control method and belongs to the technical field of electronic information. The building intelligent auto-control system DDC comprises an information acquisition unit, an information communication unit, an information processing control unit, an information feedback unit and an information display unit. The DDC functions of the subsystems of a building auto-control system are implemented by the use of the embedded and internet-of-things technology, connection to an upper platform or a field node can be of a wired or wireless manner, the problem that the subsystems of the building auto-control system have abundant protocols unable to be uniformized is effectively solved, the building auto-control system is uniformized and simplified, and the building auto-control system is higher in speed, reliability and flexibility.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to an accessory of a building automatic control system, and also relates to a building intelligent automatic control method. Background technique [0002] With the development of economy and society, people's requirements and recognition for intelligent buildings are also increasing, especially in Beijing, Tianjin, Guangzhou, Shenzhen and other first-tier cities, the proportion of intelligent buildings in the entire building is getting higher and higher. In the intelligent building system, the direct digital controller (DDC for short), as the bottom field controller, is directly connected to the control network of the equipment layer, and has autonomy and independence. It can still be independent when it is offline with the host computer Work, to achieve the effect of "decentralized control, centralized management". [0003] At present, the DDCs used in m...
