摘要

This paper presents a design scheme of a new wireless data transceiver module which is used as node in motor temperature detection system and achieves low-power of wireless transceiver module using LPC1114 s power-saving power mode integrated with the Si4432 chip's low-power module. And the paper gives a detailed description of hardware to achieve high-frequency circuit s design of RF front-end. Finally, the RF performance of the module is separately tested and energy consumption data of the module is analyzed. Performance indicators meet the demands of low-power, low-rate, high sensitivity, and real-time wireless data transmission. This module has been applied in the actual system, stable and reliable.%提出了一种用于电机温度监测系统的无线数据收发节点模块设计方案,利用LPC1114的省电耗模式配合Si4432集成芯片实现无线收发模块的低功耗.另外,针对模块硬件实现RF前端高频电路设计和前期仿真做出详细说明,模块的RF性能指标分别做了测试,分析了本模块的耗能数据,可以满足大部分的低功耗、低速率、高灵敏度的实时无线数据传输需求,本模块已经可靠、稳定地应用于系统中.
