摘　　要：针对粮库有线温度监测布线复杂的缺点,设计并实现了粮库无线温度监测系统。系统采用MSP430F149作为MCU,结合温度传感器DS18B20与n RF24L01+射频芯片完成温度的采集与数据的无线传输,同时利用C#.NET完成了上位机监测软件的开发。测试结果表明,系统能够实时地监测粮库的温度状况,并且测量精度高,符合预期设计结果,具有一定的实用价值。Because of the wiring complexity of the wired temperature monitoring system for grain depot,a wireless temperature monitoring system was designed and implemented. In the system,MSP430F149 is adopted as MCU,temperature sensor DS18B20 and nRF24L01＋ RF chip are combined to complete the temperature acquisition and wireless data transmission. The development of PC monitoring software was achieved by means of C#.NET. The testing results show that the system can implement the highaccuracy realtime monitoring of temperature status in grain depot. The design result is in line with expectation. The system has a certain practical value.
