Abstract: Aiming at improving the test efficiency of thermal components product whose testing still stays in the manual phase, a distributed monitor system was designed based on RS485 bus. The STC microcomputer was used as the processing center of Hardware, the datas of temperature and hight were collected by the testing node of the system which was established with temperature sensor DS18B20 and grating sensor, multiple products can be tested at the same time as communication network structure of system was builded with RS485 bus technology.The host computer was based on .Net and SQL2000, the real time curve was drawed of the important parameters with Zedgraph which is a open source control so that the testing process can be controlled. The results indicate that the system meets the requirements and has many advantages, efficiencyimprove can be achieved.
