1、I 移动加液车液体加注系统设计 摘摘 要要 随着工业自动化的普及和发展，控制器的需求量逐年增大提出了一种基于 PLC 对多种液 体，实现转存加注的监控和操控的控制系统设计思路，加液车是一种液体转存过程中使用的专 用车辆，常用于液体运输过程中的加注作业阶段，完成对液体的抽取和转存目的，课题要求设 计一套装置，将液体输送至目标区域，操作简便、可靠，具备一定的安全警示功能。提高了液 体转存、加注及液体运输的自动化程度和生产效率。通过可编程控制器（西门子S7-200）控制 两台直流电机实现机构在水平面内360旋转，竖直面内90的展开与收起。并且实现对加液 车各个泵、电机、液位的监视和控制，统一在触摸屏
2、人机界面上进行显示和操作，同时设计操 作面板，实现手动操作，提供必要的警示功能。另外，为了保证整个控制系统运行的稳定性和 可靠性，系统还采用了多种传感器对系统的关键环节进行保护。通过系统调试，该系统能够准 确、高效、可靠及操作方便。在现代工业中，生产过程的机械化、自动化已成为突出的主题。 随着工业现代化的进一步发展,自动化已经成为现代企业中的重要支柱,无人车间、 无人生产流水 线等等，已经随处可见。同时，现代生产中，存在着各种各样的生产环境，如高温、放射性、 有毒气体、有害气体场合以及水下作业等，这些恶劣的生产环境不利于人工进行操作。所有， 本次设计是非常有必要的。 关键字：关键字：加液车，编
