Abstract
There are many problems in the verification of temperature sensors in Chinese automatic weather stations (AWTs), including poor efficiency and low degree of automation. The verification system of prefectural metrological verification departments cannot fully satisfy the huge verification demand. To solve these problems, this paper improves the original verification system into a multi-channel automatic verification system for temperature sensors. The system architecture, hardware design and software design were detailed in turn. The system can verify eight temperature sensors at the same time, and realize fully automated operation through the control of the upper computer software. Compared with the traditional system, our system enjoys clear advantages in performance, efficiency and cost. The research findings shed important new light on temperature sensor verification.
