摘　　要：针对现代施工现场环境复杂、随机塔机分布、塔机之间实现物理连接困难且价格昂贵等问题,将工业无线通信技术应用到塔机群控制系统中。首先在令牌总线网的基础上提出了一种基于令牌传递的无线通信方式;然后在其基础上加入了自主进入与退出系统和故障检测功能;最后给出了该无线通信流程和帧格式。研究结果表明,该无线通信方式在保证系统实时性与快速性的同时,使系统具有良好的可扩展性。Aiming at the problems of the complex environment of modern construction site,the random distribution of tower cranes and the hard and expensive physical connection between the tower cranes,the technology of industry wireless communication was investigated.On the basis of Token Bus Network,the wireless communication based on token passing was presented.The function of auto login and logout system and fault detection was also added to the wireless communication protocol.Finally,the flow of this wireless communication and the format of frames were given.The results indicate that this wireless communication mode can not only make the system fast and real-time but also have the good expandability.
