The present invention proposes a remote control system for concrete mixer trucks, including a remote control, an oil pump and a controller. The controller includes a signal receiving module, a voltage output module, a steering control module and a bus receiver module, wherein the signal receiving module is used for receiving signals sent from the remote control, the steering control module is connected to the oil pump, the voltage output module and the bus receiver module are used to connect with the ECU of an engine. The remote control system for concrete mixer trucks can perform remote control of charging and discharging of a concrete mixer truck, and also can perform remote control of an remote-control throttle. Meanwhile, the controller also enables the "high speed protection" function of the engine, and the cost is low and the operation is easy. Furthermore, the invention also provides a concrete mixer truck remote control method.
Description
technical field [0001] The invention relates to the field of engineering vehicle control, in particular to a remote control system and control method for a concrete mixer truck Background technique [0002] Among the various engineering vehicles currently widely used, including concrete mixer trucks, powder material trucks, etc., the feeding and unloading process and the remote throttle control of the engine have not been controlled through the remote control system. In related technologies, the patent application number CN200920063042.4 discloses a remote engine throttle adjustment device, including a PLC controller, a numerical analog conversion module, a three-speed self-resetting switch and an engine electronic control unit. The third-gear self-resetting switch is turned on and off to adjust the voltage, and the voltage is sent to the throttle adjustment port of the engine electronic control unit to adjust the throttle speed. Throttle switch control. [0003] The remot...
