本科毕业设计（论文） 题 目： 基于PLC的自动洗车控制系统设计 基于PLC的自动洗车控制系统设计 Design of Automatic Car Wash Control System Based on PLC 摘要 如今随着生活水平的提高汽车的数量越来越多，用传统的人工清洗方式对一辆汽车进行普通的日常清洗大概会需要20分钟，人工清洗的效率比较低，清洁度比较低。自动化洗车仅仅需要几分钟，清洗效率高，可以降低劳动人员的劳动强度，节省人力、时间、水资源等。本次设计的自动洗车控制系统能够完全自动进行汽车清洗，能够提高汽车清洗效率，使得洗车变得越来越轻松、方便、快捷。本次设计的自动洗车控制系统采用三菱PLC作为控制核心，外部有清洗工具，强力吹风机，清洁剂喷洒工具等作为PLC的外部驱动设备，通过编写PLC控制程序达到对系统的控制。通过仿真软件对系统进行仿真，设计的自动洗车控制系统可以满足清洗汽车并达到自动化的要求，可以独立完成一系列洗车动作。 关键词:洗车机；PLC；逻辑控制；全自动 ABSTRACT Nowadays, with the improvement of living standards, the number of cars is increasing. It takes about 20 minutes to perform ordinary daily cleaning of a car by the traditional manual cleaning method. Manual cleaning is relatively inefficient and cleanliness is relatively low. Automatic car washing only takes a few minutes, has high cleaning efficiency, can reduces the labor intensity of workers, and save manpower, time, water resources, etc. This desing of automatic car washing control system can completely and automatically wash the car , which can improve the efficiency of car washing and make car washing easier, more convenient and faster. This design of automatic car washing control system uses Mitsubishi PLC as the control core, external cleaning tools, powerful hair dryers, cleaning agent spraying tools and other external cleaning equipment of PLC. PLC control program is written to control the system. Through the simulation of the system by simulation software, the designed automatic car washing control system can meet the requirements of car washing and automation, and can independently complete a series of car washing actions.
