Abstract

The invention provides a LonWorks bus based building automation system, which is characterized in that a BAS upper monitoring computer is connected to a plurality of routers through a TCP/IP communication protocol, each router is connected to a plurality of nodes through LonWorks, each node is an air-conditioning unit, a cold water system, a fresh air unit, a water supply and drainage system, a power transformation and distribution system, an elevator system, a lighting system, a heat exchange system or a PC (Personal Computer), and the BAS upper monitoring computer is connected to at least one PC via router relaying through the TCP/IP communication protocol. The LonWorks bus based building automation system adopts the TCP/IP communication protocol, so that extension is accomplished very easily, the openness is guaranteed, and setting of the routers particularly has excellent effects for interaction of non-specific mobile terminal; the PC is connected in a subnet, so that powerful interoperability and information sharing capacity can be provided, extremely rich functions can be provided for various platforms based on the PC, and a visual interface and the convenience of information processing can provide very good user experience.

Description

technical field [0001] The invention relates to a building automation system based on LonWorks bus. Background technique [0002] The building automation system is essentially a computer control system, and its control network is the backbone and soul of the control system. The requirements of the system for the control network mainly include the following aspects: [0003] 1) Technological advancement. The current era is an era of rapid technological development. In order to prolong the life of buildings and their equipment, advanced technology and equipment should be adopted as much as possible. Currently in the field of building automation, the most advanced control network technology is the field bus control system. [0004] 2) Integrated and coordinated operation. The main monitoring objects of the building automation system are generally heating, ventilation and air conditioning systems, water supply and drainage systems, lighting, elevators, power transformation a...
