Claim Text:
1. A pump truck stability control system comprising a detecting device and a controlling device, characterized in that, the detecting device is used for detecting current pumping state parameters, boom posture parameters, landing leg posture parameters, pump truck body position state parameters of a pump truck and external load parameters acting on a pump truck boom system; the controlling device comprises a complete machine gravity centre calculating unit and a pump truck stability control unit; the complete machine gravity centre calculating unit is used for receiving the parameters detected by the detecting device, wherein, the gravity center position of the boom system is calculated according to the pumping state parameters, the boom posture parameters and the external load parameters, the gravity centre position of the body of the pump truck is calculated according to the landing leg posture parameters and the pump truck body position state parameters, and then the complete machine gravity centre position of the pump truck is calculated according to the gravity centre position of the boom system and the gravity centre position of the body of the pump truck; and the pump truck stability control unit conducts stability control over the pump truck according to the position of the complete machine gravity centre in a pump truck stable area.
