Abstract
ZigBee wireless elevator car communication using transparent data transmission has the deficiencies of information transmission delay and low communication efficiency.In light of this,we expounded three commonly used ZigBee protocol stacks,and analysed the principle of car communication.Taking ZigBee wireless module,having the core of Stm32W108 chip,as the application platform,we presented a software optimisation strategy for wireless car communication with real-time property.The strategy collects the query frame and response frame through the ends of serial port and wireless respectively with the wireless module of elevator’s main controller,and replies elevator’s main controller information within a specified time,so as to meet the time requirements of car communication.Finally,we gave the process design of correlated software.It has been demonstrated by experiment that the optimisation strategy can meet the real-time property requirement of the system;the effective communication distance for wireless car communication system can reach 165 m,this satisfies the distance demand of wireless car communication for general high-rise buildings.关键词
