Embodiment Construction

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0062] like figure 2 as shown, figure 2 It is a schematic structural diagram of the control system of the concrete mixer truck provided by the embodiment of the present invention. The present invention firstly provides a control system of the concrete mixer truck. The control system includes:

[0063] A plurality of collection devices 1 are used to collect signals of concrete mixer trucks, and the collected signals at least include: vehicle speed signals, hydraulic pump 4 differential pressure signals, and engine load rates;

[0064] The controller 2, which is signal-connected with multiple acquisition devices, is used to judge the current working condition of the...

Abstract

The invention discloses a control system, method and device of a concrete mixer as well as the concrete mixer. The control system, method and device are used for improving the energy-saving performance of the concrete mixer. The control system comprises a plurality of acquisition devices and a controller, wherein the acquisition devices are used for acquiring signals of the concrete mixer; and the controller is used for judging the current working condition of the concrete mixer according to a received speed signal and a received hydraulic pump pressure difference signal and outputting a corresponding control signal according to the determined working condition, and is also used for storing engine universal characteristic curves respectively corresponding to a load running working condition and a no-load running working condition. When the concrete mixer is in the load running working condition or the no-load running working condition and the received engine load rate is not in the set oil consumption economic limit, the displacement of a hydraulic pump is adjusted so as to adjust the stirring rate of the concrete mixer, so that the received engine load rate can be adjusted in real time so as to be in an oil consumption economic region of the engine universal characteristic curve corresponding to the current working condition.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control system, method and device of a concrete mixer truck and the concrete mixer truck. Background technique [0002] Concrete mixer trucks are playing an increasingly important role in engineering construction. With the continuous progress of society, people have higher and higher requirements for the energy-saving performance of concrete mixer trucks. [0003] like figure 1 as shown, figure 1 It is a schematic diagram of the control system structure of the concrete mixer truck in the prior art. The chassis engine 01 of the concrete mixer truck provides power output for the chassis running and top loading mixing at the same time. The mixer truck walks. The bodywork stirring part respectively drives the stirring drum 034 through the hydraulic pump 031, the hydraulic motor 032, and the reducer 033 for stirring. Stirring speed is determined by engine speed and...
