Abstract: In this experiment, temperature measurement and control as the object, one designs temperature monitoring and control system through the software of LabVIEW to provide the experiment demonstration. The whole temperature measurement and control system is composed of the upper computer and the lower computer. The upper computer is based on the LabVIEW platform control interface by designing, and the slave computer is composed of single chip microcomputer(SCM) and temperature sensor. The communication between the host computer and slave computer is realized through the serial port communication. In this experiment, we can realize the real-time detection of the temperature on the spot, and send the corresponding control commands through the control interface, so that the microcontroller can execute the corresponding action.This system has the advantages of simple structure,strong anti-interference ability,stable and reliable,suitable for field measurement and control in harsh environments.
