| Abstract: | The paper presents the working principle and application method of verification system of temperature and humidity, points out the shortcomings of the current work and proposes the improvement solution to the system. The automatic transformation of testing system of temperature and humidity is completed by making full use of the computer technology on the basis of VB programming language, the u- sing of the existing RS232 and RS485 serial interface in the current equipment and technology of image ac- quisition USB camera, collection of statistics of real-time acquisition of temperature and humidity and veri- fication process by computers according to the verification regulations. At the same time, aiming at the problems in the process of application, the paper proposes further improvement ideas and methods. The functions and an interface of the equipment as well as cheap USB camera available in the market are made full use of in the transformation, and automated test process is realized so that a lot of manpower is saved with work efficiency and testing accuracy improved. |
