中文摘要：

基于2.4GHz无线SOC芯片nRF24LE1设计了一种采煤机无线遥控系统。系统以nRF24LE1为核心,包括掌上摇控器、机载收发装置和机载PLC三部分。机载收发装置采集采煤机的各种工作参数,通过无线方式将数据传送至掌上遥控器,并实时显示在LCD上。机载收发装置接收到按键指令后,经机载PLC装置来控制采煤机的各种动作。由于采用了高性能的嵌入式微处理器智能射频收发SOC芯片nRF24LE1,系统具有低成本、低功耗及性能稳定等特点。

英文摘要：

A remote control system for the shearer was designed based on 2.4 GHz wireless SOC chip nRF24LE1.The system used nRF24LE1 as the core,and consisted of three parts that were palmtop remote controller,onboard transceiver and onboard PLC.The onboard transceiver collected all working parameters of the shearer and transmitted the data to the palmtop remote controller in wireless way,then the data displayed on LCD in real-time.At the same time,when receiving the button instructions,the onboard transceiver controlled all kinds of shearer actions by the onboard PLC.With the embedded high-performance microprocessors intelligent RF transceiver SOC chip nRF24LE1,the system possessed the features such as low cost,low power consumption and stable performance etc.
