Abstract In order to ensure the normal operation of various hydrological monitoring equipment,a detailed introduction is given on the method of using PID algorithm to achieve realtime sensing,magnitude judgment,and temperature power adaptive adjustment of peripheral temperature.According to different application scenarios,multiple heating modes such as contact and noncontact modes are automatically switched.Through technological breakthroughs and product optimization,this technology has been applied to the upgrading and transformation of JEZ series rain and snow meters,further optimizing the heating control function and insulation performance of the rain and snow meters.The research results provide support for improving the system performance and environmental adaptability of rain and snow meters.
