摘　　要：立体车库智能控制系统中一般采用的是基于LonWorks技术的纯分布式无主系统。为了解决在这种无主的分布式系统中对车辆的存取控制,使用LON控制模块实现了一种新的、方便的立体车库智能控制节点的设计方法。介绍了LON控制模块的主要功能特性,并设计了其与I2C总线接口的键盘及LED驱动器芯片ZLG7290B之间的硬件接口电路。给出了相应的程序实例。实际运行结果表明,该设计能保证控制节点实时地传输数据,稳定地工作。A pure-distribution system based on LonWorks technology was often adopted in three-dimensions garage control system.A new and convenient three-dimensions garage control node design method was achieved by using LON control module to solve the problem of the vehicle s access control in the masterless distributed system.The main functional characteristics of LON control module were introduced,its keyboard with I^2C bus interface,and hardware interface circuit with LED driving chip ZLG7290B were designed.The related program example was given.The practical operation result showed that the design could control nodes transfer data in real time and work steadily.
