The invention discloses a control method, device and system capable of preventing accidental working state switch of a concrete pump truck. The control method includes: detecting whether a power output switch transmits a switch signal or not when the concrete pump truck is in a driving state; if so, extracting a transfer case rotation speed signal and gearbox state information from a chassis controller; transmitting a reverse control signal to a power take-off electromagnetic valve to facilitate that working state of the concrete pump truck can be changed into operation when transfer case rotation speed is zero and the gearbox is in a neutral position; simultaneously transmitting a switch control signal to the chassis controller to facilitate the chassis controller to adjust output power of an engine. By detecting the transfer case rotation speed and gearbox state, current working state of the concrete pump truck can be obtained accurately, working state switch caused by misoperation can be avoided effectively, and safe and reliable operation of the concrete pump truck can be guaranteed.
Description
technical field [0001] The invention relates to the field of control, in particular to a control method, device and system for preventing accidental switching of the working state of a concrete pump truck. Background technique [0002] Concrete pump truck is a special conveying equipment for concrete in the construction industry. It is transformed from the truck chassis. It is equipped with motion and power transmission devices, pumping and mixing devices, distribution devices and other equipment assisting equipments. The power of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power transfer case, and the hydraulic pump pushes the piston to drive the concrete pump truck to work. In addition to driving the pump truck, the engine of the concrete pump truck is also used to drive working devices such as the pumping mechanism, the mixing mechanism, and the material distribution mechanism. The power of each work...
