| Abstract: | On the basis of virtual instrument design philosophy, a real-time temperature measurement and control system has been designed by taking LabVIEW8.5 as the software development platform and the low power consumption SCM P891.V51RD2 as the hardware kernel. In this system, the digital temperature transmitters TMP112 are adopted, they coordinate with the SCM to realize the temperature acquisition on the site. The telecommunication between the SCM and the host computer is realized through ZigBee wireless communication modules SZ05, and the data are displayed, analyzed and stored by using the software platform, mea,twhile, the PID control of the temperatures is implemented. The system is of lower consumption, higher measurement accuracy, user-friendly, easy accessibility, better expandability and lower cost. |
