Abstract


Wheeled mobile machinery is a class larger large load of construction machinery , generally use full hydraulic drive , the enhancement of the performance of the whole not only rely on the continuous optimization of mechanical and hydraulic drive system has a comprehensive set of reliable intelligent control system to become improve walking the overall performance of the mechanical key . Increasingly widespread for mobile applications , the development of an intelligent control system has important practical significance . Detailed analysis each function of the control characteristics of the hydraulic drive system and mobile machinery control characteristics and the actual construction conditions , to establish a distributed architecture model hardware and software system , and application of CAN bus communication technology to build reliable , real-time communication network, based on the initial planning of the basic functions of the vehicle . RC Series selection of very popular embedded system controller as the control core , according to the network topology of vehicle control area divided . And to determine the main idea of decentralized control based on the centralized management , from the control node , then each node where the electrical control cabinet component selection and design of electrical schematics . Further refine the function of each part of the system and its control structure , the increase of the specific fault as the possible misuse of the judge and alarm handling mechanism . The planning layer the BODAS development platform designed the master controller program and from the node control program , monitor the vehicle while developing interactive interface . Site debugging functionality of the entire system , the results of comparative tests , analysis of various problems , and gradually improve the control system .
