Abstract

The invention provides a control device, method and system and an electric mixer truck. The device comprises a driving motor controller and a top-mounted motor controller. The alternating current output end of the driving motor controller is electrically connected with the driving motor through a first switch. The alternating current output end of the top-mounted motor controller is electrically connected with the top-mounted motor through a second switch. The alternating current output end of the driving motor controller is electrically connected with the alternating current output end of the top-mounted motor controller through a third switch. According to the device, the method, the system and the electric mixer truck, mutual backup of the driving motor controller and the top-mounted motor controller is realized, potential faults of the electric mixer truck are reduced, and the safety and the operation efficiency of the electric mixer truck are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a control device, a method, a system and an electric mixer truck. Background technique [0002] During the use of electric mixer trucks, the top-mounted mixing drum drive system is used as the power source for the mixing drum to mix concrete. The core components of the current top-mounted drive system are the top-mounted motor and the top-mounted electronic control controller. The DC power of the power battery is reversed into three-phase AC power, and the output power of the bodywork motor is driven through the three-phase cable to drive the mixing drum to rotate. [0003] Since the mixing drum is filled with concrete, the bodywork drive system must ensure that the mixing drum can normally output power to drive the mixing drum to rotate in all scenarios where the concrete is installed, so as to prevent the concrete from solidifying. However, at present, the elect...
