The invention provides a novel subsoiler intelligent management system which comprises a server and a vehicle terminal. The server communicates with the vehicle terminal. The vehicle terminal is fixed to a subsoiler and comprises a controller, a GPS, a GPRS, a depth sensor, a speed sensor, a facility identification sensor. The GPS, the GPRS, the depth sensor and the speed sensor communicates with the controller. The GPS, the depth sensor and the speed sensor are bound with the facility identification sensor one by one. The controller transmits the working information to the server through the GPRS, and the server processes the working information to form a chart. Compared with the prior art, the system has the advantages that the functions of fixed point positioning, working trajectory, image obtainment, working amount calculation, deep ploughing detection, farm machinery management and the like are closely combined, and thus the farm machinery management is more convenient.
