Abstract:
Aiming at the troubleshooting of AWS temperature signal interference in the north suburbs of Taiyuan, a detailed analysis is made of the signal transmission mode and structure of the DYYZII automatic weather station,the distribution,working principles of the equipment grounding grid,and earthing resistance measurements, as well as the influence of metal oxides on actual grounding effectiveness in the grounding wire and the origin of the temperature sensor signal interference. The earthing resistance correspondence between requirements and actual grounding effect is discussed,and it is point out that meeting the requirements of grounding resistance values is not necessarily equal to meeting the requirements of the actual grounding effect. The troubleshooting and verification process indicates that there is direct impact of metal oxides on the conductivity of the grounding wire,which provides an analytical solution for future AWS temperature signal interference researches.
