Abstract: Hydraulic design method, device and equipment for mobile drip irrigation system are provided. Different distances between drip-lines, a depth of a bottom boundary, a flux of infiltration boundary and soil hydraulic parameters are input into a simulation model, and output parameters of the model including a soil water content at each observation point and an amount of deep percolation loss under the different distances at the same irrigation depth are acquired. An optimal distance between drip-lines is obtained according to an installation cost function, the soil water content at each observation point and the amount of deep percolation loss, and lengths of drip-lines matched with the optimal distance are obtained. Structural parameters of the irrigation system and a designed irrigation depth are obtained to determine working parameters. The irrigation system with the optimal distance and the matched lengths of drip-lines is controlled to irrigate crops based on the working parameters.

Abstract: An electronic device includes a touch sensor, a touch sensor, and a controller. The touch sensor is configured for detecting a touch action on a touchscreen and reporting touch information. The proximity sensor is configured for detecting nearness of a target object and reporting a proximity information. The controller is connected to the touch sensor and the proximity sensor, the touch sensor and the proximity sensor are putted in a same circuit, such that the touch sensor and the proximity sensor are controlled by the same controller. When the proximity sensor detecting nearness of the target object, the controller will prevent touch report event.
