摘要
在简要介绍了无线射频通信芯片nRF903和单总线温度传感器DS18B20的性能和特点的基础上,根据粮库测温系统的特殊现场要求,利用低功耗、高性能的单片机LPC932为核心构成了一个多点的无线粮库测温系统,具体介绍了系统中测温器的硬件接口电路、温度传输协议和无线收发流程。
On the basis of introduction of wireless communication IC nRF903 and 1 wire temperature sensor chip DS18B20s functions and characters in brief, this paper designs a multicast grain depot temperature test system using low power consumption and high function microporcessor LPC932 as core chip according to grain depot temperature test system special locale requirement and discusses interface circuit,temperature data transport protocols and software flow chart of temperature test device in this system in detail.
