| Abstract: |
| 【Objective】In order to save water for irrigation in greenhouse, a three-degree-of-freedom upside-down mechanical arm irrigation device that can move along the track. At the same time, crops can be guaranteed to grow in the optimal moisture soil, so as to improve crop yield. 【Method】In this paper a uniform distribution method of soil moisture sensor based on potential function and potential field theory was presented, which can accurately collect soil moisture in the area. Using fuzzy control to control soil moisture more precisely. To quickly respond to control instructions, PI method was used to control the motor of each joint. 【Result】The calculation, analysis and simulation results show that: PI control enables the device to quickly respond to commands and move, the response time is less than 1s. The method of uniform distribution of sensors is combined with the fuzzy control method of soil moisture, that can precisely control the solenoid valve opening and closing time, the fuzzy control response time is less than 1s. 【Conclusion】The device model is built, the response speed of device control is fast, and the motion path and action can be executed according to the setting. |
