The Design of an Automatic Recording and Sampling System for Leakage Soil Moisture
HE Dai-jie · Journal of Southwest University · 2013
A kind of system for collecting soil leakage moisture with automatic recording is designed.The system can control all the stepping motors and solenoid valves with coordinated work.The soil leakage moisture from the percolating pools flows into a container,and when the water reaches the scheduled level,the stepping motor begins stirring.After that,it starts to sample.When sampling is completed,the device drains off the water in the container automatically.As the above steps after controlling the turntable motor,it can complete the next sampling operation.The reminder equipment will not work until all the samplings are over.The design is a mechatronics system with stable working,high automation and scientific sampling,and it can save a lot of labor,material and financial resources.
