[Abstract]:Aerial working vehicle is a kind of mechanical equipment used in aerial work. The aerial work vehicle can lift the staff and materials to the designated position to carry on the maintenance and installation through the work platform. With the development of society and science and technology, people put forward the requirements of operation flexibility and safety comfort in the use of aerial vehicles. In order to improve the operation performance and reduce the labor intensity of the staff, this paper studies and designs the electro-hydraulic control system of the working device of the whole vehicle, taking the self-propelled curved arm aerial work vehicle as the object and referring to the foreign advanced technology. First of all, it introduces the basic structure and working principle of the self-propelled curved arm aerial working vehicle, and analyzes in detail the composition and working principle of each loop in the hydraulic system of the working device of the aerial work car, including the stretching, changing amplitude, turning table and swinging arm. Working platform swing and leveling loop. Then, according to the characteristics of hydraulic system, the input and output signals of the control system are determined, and the overall hardware structure of the control system is designed. The special EPEC control module of the construction machinery is chosen as the hardware platform of the control system. The communication between the system modules is realized by using the CAN bus technology, so that all the control instructions and data information of the system hardware can be shared. The operation control and the main parameter display of the working device of the aerial work vehicle are realized. Finally, on the basis of compiling the flow chart of each movement control of the working device, the work device control system of aerial vehicle is realized by CODESYS programming software. In the program design, I / O initialization module and CANOPEN initialization module program are written. Then take the amplitude change action as an example, completes the amplitude change control program writing.
