摘要
以高性能无线通信芯片nRF9E5为基础,针对某大坝混凝土浇筑工程实际,设计了一套简单可靠的短距离无线通信系统,较好地解决了短距离下低成本的多点对多点无线通信问题。依据实际工况设计了系统方案,给出了平车控制部分和车载子系统的硬件电路,并对软件设计中的通信策略、工作频段、通信协议、数据校验等问题作了论述。
A wireless communication system is proposed for the casting practice of a darn construction based on nRF9E5 a high- performance chip. This system can be easily used in short-distance wireless communication scenarios with high reliability and low cost. The design scheme is presented according to the dam project. The control plan, the hardware circuit and the software design including communication strategies, the working frequency, communication protocols, data checking schemes and so on are discussed.
