A temperature measurement system based on single-wire digital temperature sensor DS18B20 was designed, and the characteristics, control commands and time sequence of DS18B20 were presented. The hardware design of the temperature measurement system were designed by using Proteus software, and the main program and DS18B20 driver program were designed by using Keil software. Finally, the temperature measurement system was simulated by Proteus software. And the system development efficiency was improved and the favorable simulation results were obtained.%设计了一种基于单总线数字温度传感器DS18B20的测温系统,给出了DS18B20传感器特性和控制命令及时序,在Proteus环境下进行了测温系统硬件设计,同时采用Keil软件完成了系统主程序、DS18B20驱动程序的设计；最后进行了系统Proteus仿真,提高了系统开发效率,并获得了良好的仿真实验结果.
