【摘要】：本课题是以SLJ900型流动式架桥机为背景，结合用户需求及目前电液控制技术发展现状，，设计了此种基于CAN总线的分布式独立单元行走驱动控制系统，此系统已经成功通过整机调试并运用某标段运架梁现场。针对SLJ900型流动式架桥机的功能特点，本文主要对SLJ900型流动式架桥机的液压行走控制系统进行研究。SLJ900型流动式架桥机采用分布式动力舱全液压驱动，液压行走控制系统作为此款运架设备的重要组成部分，其性能和功能的好坏对于SLJ900型流动式架桥机整体性能有着非常重要的影响。因此，研究一种性能稳定、运行可靠的液压行走控制系统有着非常重要的现实意义。本液压行走控制系统硬件方面采用力士乐RC6-9控制器为主控制器，RCE12-4控制器为从控制器，主、从控制器采用CAN总线进行数据通讯。主控制器接收从控制器发送来的压力数据，通过逻辑判断及PID控制算法，向从控制器发出控制信息，达到前、后车同步控制的目的。从控制器通过压力传感器采集压力信号并执行主控制器发出的控制信息。人机交互界面（HMI）采用力士乐DI-3显示器，界面友好，操作方便，通过CAN总线接收从主控制器发过来的整机状态信息并予以显示，同时显示器也能通过CAN总线向主控制器发送数据。通过在实验室模拟及现场调试，本控制系统主从控制器工作正常，性能稳定，具有较强的抗干扰能力，完全符合设计要求。
[Abstract]:Based on the background of SLJ900 mobile bridge erecting machine, combined with the user's demand and the current development situation of electro-hydraulic control technology, this paper designs a distributed independent unit driving control system based on CAN bus. The system has been successfully debugged and used in a certain section of the site. In view of the functional characteristics of SLJ900 mobile bridge erecting machine, this paper mainly studies the hydraulic movement control system of SLJ900 mobile bridge erecting machine .SLJ900 mobile bridge erecting machine adopts the full hydraulic drive of distributed power cabin. Hydraulic walking control system is an important part of this equipment, its performance and function have a very important impact on the overall performance of SLJ900 mobile bridge erecting machine. Therefore, the study of a stable and reliable hydraulic control system has a very important practical significance. In the hardware of the hydraulic walking control system, Rexroth RC6-9 controller is used as main controller and RCE12-4 controller as slave controller. The master and slave controller adopt CAN bus for data communication. The main controller receives the pressure data from the controller and sends out the control information to the slave controller through logic judgment and PID control algorithm. The pressure signal is collected from the controller through the pressure sensor and the control information from the main controller is executed. The Human-Computer Interface (HMI) adopts Rexroth DI-3 display, which has friendly interface and convenient operation. It receives and displays the state information from the main controller through CAN bus. At the same time, the display can also send data to the main controller through the CAN bus. By simulating and debugging in the laboratory, the master-slave controller of this control system works normally, has stable performance, has strong anti-interference ability, and completely meets the design requirements.
