Abstract
The target of intelligent control system is through the use of computer technology, network technology, control technology and integration technology to establish an office and even the city's comprehensive information services and management systems。The design focuses on design LonWorks control system。
Echelon Introduces Lonworks field bus, a Lonworks control network can have from 3 to 30,000 or more nodes: sensor capabilities, the implementation of functionality, user interface and control functions. Because do not like the traditional control system in the central controller, Lonworks distributed control technology demonstrated high reliability and system response, and reduce system costs and operating costs 。
LonWorks network communicate using LonTalk network standard language,LonTalk protocol is the core of LonWorks technology,LonTalk protocol composed by a variety of underlying protocols. The agreement has now become the standard for many organizations.
In order to achieve comprehensive control, achieved with the electrical system of linkage control, PC control, meter reading, remote monitoring, must be installed LonMaker and WebAccess software and configuration software.
