摘　　要：介绍了基于虚拟仪器开发的一多路测温系统,它以DS18B20作为温度传感器,通过单总线协议实现多路温度巡回测量,数码管显示温度值,并将温度值通过串口通信送上位机,由上位机软件LabVIEW进行处理(存储、记录、显示等),与传统的温度传感器组成的测温系统相比更简单,显示了单总线器件与虚拟仪器相结合的优越性。The multiple channel temperature measurement system based on virtual instrument is introduced.In the system,DS18B20 is a temperature sensor,it realize the multiple temperature measurement by 1-wire bus,the temperature is displayed by LED and sent to upper computer by serial bus for saving,indicating and so on,the system is more simple compared with that composed of the additional temperature sensor,which shows the superiority of the 1-wire bus and virtual instrument.
