In order to promote the development of mechanization of vegetable production and increase the level of intelligent, an intelligent farming device for vegetables was designed based on mechanical design, pressure sensing, WiFi transmission, internet communications and Android mobile phone terminal control. The device included a farming mechanical component and a control system based on STM32 MCU, a mobile client software was developed based on Android, which can realize the remote viewing and manipulation functions. According to the farming instructions of the Android client, the end effector can select different functional heads to complete the corresponding farming action;through the capacitive soil moisture detection function head to monitor the soil moisture;positioning and quantitative sowing was performed through the sowing function head and gantry positioning;through the liquid material function head and PVDF pressure sensor installed at the liquid pipeline interface, to achieve liquid material delivery jam and flow monitoring, complete delivery of liquid material precision;the crop image information was acquired by CCD camera, and the weed identification algorithm was developed based on BP neural network to realize weed identification. The test results showed that the qualified rate of the plant spacing can reach 9513%, and the rate of misuse was 4.86%;the liquid material delivery function was relatively stable and uniform, and the maximum error was no more than 5.4g.
