摘要
主要介绍了LPC932与nRF903硬件接口和通信协议,为了降低系统的功耗,还可利用LPC932的实时时钟功能实现测温器的交替唤醒工作和睡眠的功能,在节电的同时也减少了对环境的电磁辐射。不仅适用于粮库测温系统,还可用于需要数据传输的其他测控领域,如小型数据网络、安防系统、遥控系统、玩具、机器人控制等方面。对无线通信芯片nRF903和单总线温度传感器DS18B20的性能和特点作了介绍。利用低功耗、高性能的单片机LPC932构成一个无线的粮库测温系统,具体介绍了系统的硬件构成和软件流程。
The LPC932 and nRF903 hardware connection and the communication protocol are mainly introduced. In order to reduce the power loss of the system, the function of LPC932 real-time clock may be used to realize the work and sleep function in turn, which saving electricity and reducing electromagnetic radiation to environments. LPC932 may be used in temperature-test system used in grain storages and any other systems needing observation and control of data transmission such as the small data network, safety protecting system, remote control system, toy, robot control and so on. The performance and characteristics of wireless communication chip nRF903 and the single-main-line temperature sensor DS18B20 are also introduced. A wireless temperature-test system for use in grain storages is constructed using monolithic integrated circuit LPC932, and its hardware constitution and software flow are specifically introduced.
