摘要
研究了一种机场应急救援拖车的同步电气控制系统。基于ARM-Linux平台,上位机以ARM9为核心,下位机以PLC为核心,使用Qt/Embedded和梯形图完成对上、下位机的GUI和程序设计,上下位机采用485通讯。连接试验模型和控制系统,实现了用遥控器控制机场应急救援拖车同步转向,通过对模型的测试,其可行性已被初步的实验证实。
A synchronous electrical control system of airport emergency resc, ue trailer is designed. Based on the ARM- Linux platform, the GUI and programming design of host and master PC is completed by using Qt/Embedded and Ladder, and the host and the master computer take ARM9 and PLC as the core respectively, and they communicate through 485. By connecting the testing model and control system, the simuhaneously turning function controlled by remote controller is achieved. The teasibility of the system has been confirmed by testing the model.
