Abstract: The paper discusses the principles and shortcomings of the concrete mixer truck’s hydraulic control mechanism. The stepper motor technology controlled by the electrical impulses is used to develop a new digital display control device, and determine design principle and implementation process of the electronic control part. At the same time, it develops control device’s digital display mechanism and wireless remote control devices. At last, it compares the performance advantages and disadvantages between the traditional mechanical control handler and the digital display remote controller according to the engineering practice.

Abstract: The paper studies the principle and the flaw of the hydraulic control organization of concrete mixer truck, and designs one kind of brand-new Digital Display control devise. According to principle of the new Digital Display control devise, it has determined shifting block’s displacement quantity and the displacement limit of the key component of unloading Control devise. At the same time, the design has realized the accelerograph’s control device, and compared with the merit and demerit between the new and old control devise based on the basis of the practice application.
