放样测量中的ZigBee无线传输系统设计

针对传统放样法因放样人员与观测人员交流不便而影响施工进度的问题,提出一种ZigBee无线传输系统设计方案;给出了系统总体结构,并详细介绍了系统软硬件设计。该系统采用星形网络结构,通过与全站仪相连的网络协调器节点将放样点与目标点的差值发送给由跑点人员手持的RFD节点,并将结果显示在液晶显示器上。测试表明,该系统数据传输及时、误差率低。

Design of ZigBee Wireless Transmission System in Setting-out Survey

Traditional setting-out methods always affect construction schedule because of inconvenient communication between setting-out person and the observer,so the paper proposed a design scheme of ZigBee wireless transmission system,and described overall structure and design of hardware and software of the system.The system uses a star network structure,sends difference between setting-out point and target point from coordinator node connected with total station instrument to RFD node held by setting-out person,and finally displays the results on LCD.The tests showed that the system can realize real-time data transmission with low error rate.
