By introducing PID control technology into the hydrogeological pumping test method,a hydrogeological pumping test system based on PID control is designed and built.Combined with water level,flow sensors,and electronic automatic recorders,the relationship between water level and predetermined pumping level is monitored in real time.The PID algorithm is used to automatically adjust the frequency of the variable frequency water pump to control the pumping flow.The application effect of the hydrogeological layered pumping test in a large-scale water resource allocation engineering geological survey shows that the system can quickly reach the predetermined water level and stabilize the water level in the early stage of pumping,and achieve automatic data collection.The application shows that the system can effectively improve the accuracy,efficiency,and data quality of experiments,providing new technical means for hydrogeological exploration under complex geological conditions.
