In the embodiment of the present application, the control priority of the display control screen is higher than the control priority of the hard-wired operating switch and the upper-mounted rear control switch. In other words, if there is a control signal on the display control screen, the upper-mounted control instruction is executed according to the screen instruction; if the display control screen signal is no, the cab hard-wired control switch signal is further judged. If such a signal is present, the upper-mounted control instruction is executed according to the cab hard-wired switch execution signal.

The user controls the chassis structure and / or the mixer structure by adjusting the soft switches of different functions on the display control screen, hard-wired operation switch or upper rear control switch. Furthermore, the control system can receive an external control signal initiated by the user, for example, the external control signal includes a control instruction for the mixing tank assembly, and sends the external control signal to the vehicle controller. The vehicle controller first determines the sender of the external control signal, and determines whether the external control signal needs to be executed based on the control priority of the sender.

[0051] Optionally, if it is determined that execution is required, the speed and torque of the stirring drive motor are calculated according to the internal preset program, and the calculated speed and torque are sent to the high-pressure controller, so that the high-pressure controller supplies energy to the stirring drive motor according to the speed and torque, so that the stirring drive motor operates at the set speed and torque, driving the stirring tank assembly to work.

[0052] Furthermore, the vehicle controller feeds back the calculated speed and torque to the display control screen of the control system for display.

[0053] After use, the vehicle key door of the concrete mixer truck needs to be closed to power off the high-voltage controller and stop the mixing tank assembly from rotating.
