摘要
介绍了一种以EZ-USBFX2单片机为主控单元,使用PTR8000作为无线数据收发模块的点对多点无线数据采集传输系统的设计与实现。系统中作为主控单元的EZ-USBFX2单片机负责启动,停止远端模块数据采集动作,以及按照点名方式命令远端模块传回数据。该系统是针对桥梁振动测试而设计的,按照后期数据分析需要,要求各远端模块实时采集的数据相位一致。文章重点讨论了一种实际可用的满足以上要求的非高速数据传输点对多点无线动态数据采集传输协议,给出了实现方法。
This paper introduced the design and implementation of a multicast wireless data acquisition and transmission system, which used EZ - USB FX2 single - chip microcomputer as the main control unit and PTR8000 as wireless data transceiver. In this system, EZ - USB FX2 as the main control unit was in charge of starting and stopping remote modules, as well as calling them to transport the data acquired to it. This system was designed for bridge vibration test. According to the need of data analysis latter, keeping the phase of the data from different remote modules same was required. The paper focused on an available dynamic multicast wireless non-high-speed data acquisition and transmission orotocol, which can well meet the requirement above.
