On site bus building integrated control system based on LON bus technique

Abstract

The invention relates to a field bus building integrated control system based on a LON bus technology. The integrated control system consists of a LonWorks / IP server, an Internet server, a LON DDC controller, an LNS server and a remote client; moreover, the system adopts an intelligent building management system, namely a typical structure of two-level network and three-level management of an intelligent building management system (IBMS), that is to say, a two-level network structure formed by a field bus network, namely LonWorks bus network, and a local area network consisting of a client / server structure, as well as a three-level management structure formed by a field direct digital controller (DDC) for control, a process management server and remote client management are adopted. The field bus building integrated control system has the characteristics of intact structure, advanced technology, visualized image and wide coverage, and is suitable for field bus building integrated control systems involved in university curriculums such as 'Building Automation Technology and Application' and 'Building Automation System Integration Technology'.

Description

technical field [0001] The invention relates to a building control network system, in particular to a fieldbus building integrated control system based on LON bus technology. Background technique [0002] Networking is the development direction of the intelligent building control system, and the building control network system based on the LonWorks bus is a mainstream in the development of intelligent buildings at present. The LonWorks bus is a multi-point, multi-station, multi-variable, distributed intelligence, two-way Serial digital communication link. The network system based on the LonWorks bus directly communicates with the on-site measurement, control and execution equipment. It is a new type of intelligent fully decentralized structure, which is especially suitable for the huge, decentralized and diversified application characteristics of the building control system. In 2006, the LonTalk protocol has become China's National Standardization Guidance Technical Documen...

Problems solved by technology

The only communication channel between devices on different networks is through a dedicated gateway, which is a step forward from a dedicated system, but the logical control between devices is limited and cannot directly form a point-to-point control relationship, so the system is under the hierarchical structure. The first layer is still closed, which limits the fully open technical features of LonWorks
