Design of Network Variables Based on Lonworks Elevator Group Control System

摘要

In order to realize information transmission of modules in elevators group control system,we design network variables to carry out the design of external interface.This paper put forwards network variables multiplexing technology to design network variables.The networks variables include multi-status and multi-function.The result of experiments showed that network variables multiplexing technology are rationality.The method can reduce the amount of network variables and can debase network congestion.It also can improve respond speed of elevator group control system.Network variables multiplexing technology is a kind of effective and practical method.
