Research And Realization On Driving Control System Of Heavy Engineering Transporter

Heavy Engineering Transporter is a heavy engineering machine, which is widely used in ship manufacturing and the construction of road and bridge. It is the essential and special machine in the transport of big component. It is, adopting full hydrostatic drive, equipped modern electronic control technology, a novel engineering machine integrated with mechanical, electronic, hydraulic and control technology. The hydraulic transmission and control technology is playing an important role in modern construction machinery, and increasingly affection the whole performance of construction machinery. It is of great significance to develop the hydraulic control technology for enhancing the whole performance and reliability of construction machinery.Firstly, this paper analyzes the transmission style of diving machine in detail and selects hydrostatic transmission as transmission manner of Heavy Engineering Transporter. Then we analyze the principle of hydrostatic transmission, control style of hydraulic components and the basic driving theory of transporter and pay attention to solve the problems of driving speed-regulation control when transporter runs on different road surface and differential speed control ensured every wheels pure roll when transporter is in swerving.This paper brings forward the overall control scheme of the driving system of Heavy Engineering Transporter, which mainly controls the driving variable pump for regulating driving speed and eight driving variable motors for achieving differential force in driving control system. And how to realize the control scheme by hardware and software is mainly discussed in this paper. RC6-9 controller is adopted as main controller of the hardware circuit of system. Every main controller and monitor exchanges data by CAN-Bus so that to realize cooperative control of multi-task. The software of system consists of driving speed-regulation module realizing driving speed-regulation control and skid-judgment module realizing differential force control and differential speed control. Moreover, man-machine display interface is designed in thesystem so that the running status of transporter can be monitored and diagnosed in real time.Finally, the conclusion is drawn and the trend in process decision-making research is put out.
