基于LabVIEW的单片机温度自动测试系统

An Automatic Measuring System of Temperature of Single Chip Microcomputer Based on LabVIEW

冷库的温度是在实际应用中的一个重要指标,为此笔者设计开发了此单片机巡回测试系统,使其能对冷库的各冷冻室的温度巡回测试并加以处理。该系统由AT89C51单片机和温度传感器组成室温的数据采集系统,利用PC机上的RS 232串行口实现数据的串行通讯,使用LabVIEW虚拟仪器软件完成上位机串行通讯程序和前面板程序的编写。实验证明此系统取得良好的测试效果。

To test the temperature of icebox, we developed the automatic measuring system of temperature of single chip microcomputer. RS232 interface on PC realizes the data communication between microcontroller and PC. Program on PC are written in LabV1EW software. The experiment has proved that the automatic measuring system is satisfied.
