The invention relates to a collaborative operation system and method, a concrete pumping apparatus and an agitating truck. A detection device in the collaborative operation system detects concrete level information and/or concrete remain information in a hopper; and a control device receives a detection signal and controls the discharge speed of the agitating truck according to a prestored control strategy, so that the concrete in the hopper can not overflow or be pumped emptily, or the level of the concrete in the hopper is maintained to a certain level, thereby implementing collaborative operation between the pumping truck and the agitating truck. By using the invention, the pumping truck and the agitating truck can implement collaborative operation at the concrete construction site, and one operator can be saved. The invention also provides a pumping apparatus provided with the detection device and an agitating truck provided with the control device, so that the pumping apparatus and the agitating truck have the conditions for collaborative operation. Besides, the invention also provides a collaborative operation method, according to which the collaborative operation between the agitating truck and the pumping equipment apparatus can be controlled.
