摘　　要：设计了一种基于DS18B20数字温度传感器、MSP430F149微控制器和NRF24L01无线收发模块等的多路无线温度检测系统,并给出了系统硬件设计和软件流程,在上位机程序中引入了数据库,最后分通道存储和显示.除此之外,还将下位机和上位机进行分开设计,下位机可以独立完成整个系统的基本功能,系统的可扩展功能由上位机及PC机来承担.系统测温范围为0～100℃.In our report, based on digital temperature sensors DS18B20, microcontroller MSP430F149 and a single chip RF transceiver NRF2401, a multipoint wireless temperature measurement system were designed and the system hardware design and the software procedures were proposed, and in order to store and display data in different channels, the host computer program interacted with the database. Additionally, low computer was able to independently accomplish the basic functions of the entire system, and all of the external functions were ac- complished by the PC. The temperature measurement bound was 0--100℃
