【摘要】：车辆作为人们工作生活中重要的交通工具。目前国内汽车保有量不断攀升,带来了庞大的汽车服务市场。尤其是车辆的清洗工作越来越受到人们的重视,因此对车辆清洗控制的自动化,节能化的要求越来越高。本课题旨在研究一种车辆清洗系统。系统为实现对车轮定位清洗与机构的平稳运行。引入了图像处理算法与电机控制算法。通过改进的Hough算子,确定车轮位置,达到定向清洗目的。在机械运行方面整合矢量控制技术(PMSM)完成对电机驱动,避免对伺服器的依赖。车辆清洗端硬件开发采用S3C2440、DSP2812、USR-780等。清洗端接收到清洗指令后,通过S3C2440控制DSP电机模块、风机组、水阀、水蜡阀、底喷等协同完成对车辆不同部位的清洗工作。根据系统功能设计了系统软件部分。开发了用户与管理员APP,包括人机交互界面设定,数据指令信息接收与发送;在车轮定位过程中,解决了图像采集模块与控制中心的数据交换、图像的读取及图像处理等问题。同时完成了清洗端的电机控制,机构运行进程控制;外部通信模块,检测部分的软件设计工作。客户可以通过手机APP平台预约清洗时间并缴费,并可根据个人的需求选择不同的清洗服务模式;管理员可以通过APP查看清洗端的清洗数据,以及实现对清洗端工作状态的控制。并改进了清洗执行控制系统。提高了自动化程度和工作效率。改变目前车辆清洗过程中,客户和管理端与清洗端相互独立的现状。设计实现车辆清洗无人化,自动化。达到降低造价成本,缩小系统体积的要求。最后对自助洗车系统关键环节进行了相应的仿真与测试。其中包含电机运行控制的算法仿真、图像处理在车轮定位中的应用测试、移动端APP与清洗端的数据交换测试。实验表明自助洗车系统关键技术环节的研究设计满足实际需求。本课题对洗车领域的研究发展起到一定的推动作用。
[Abstract]:Vehicles are important vehicles for people to work and live. At present, the amount of domestic automobile ownership is rising, which brings a huge market of automobile service. Especially, people pay more and more attention to the cleaning of vehicles, so the requirement of automation and energy saving of vehicle cleaning control is becoming higher and higher. The purpose of this paper is to study a vehicle cleaning system. The system realizes the wheel positioning cleaning and the smooth running of the mechanism. Image processing algorithm and motor control algorithm are introduced. Through the improved Hough operator, the wheel position is determined to achieve the purpose of directional cleaning. Integrated vector control (PMSM) in mechanical operation to drive the motor, avoiding the dependence on the server. The hardware of vehicle cleaning end is developed with S3C2440 / DSP2812USR-780 and so on. After receiving the cleaning instruction, the cleaning end controls DSP motor module, wind turbine, water valve, water wax valve and bottom spray to complete the cleaning of different parts of the vehicle by S3C2440. The system software is designed according to the system function. The user and administrator app is developed, which includes human-computer interface setting, data instruction information receiving and sending, and the problems of data exchange between image acquisition module and control center, image reading and image processing in the course of wheel positioning. At the same time, the motor control of the cleaning end, the process control of the mechanism operation, the software design of the external communication module and the detection part are completed. Customers can book cleaning time and pay fees through the mobile phone app platform, and can choose different cleaning service modes according to individual needs; administrators can view the cleaning data of the cleaning end through app, and realize the control of the working state of the cleaning end. The cleaning execution control system is improved. Improved automation and working efficiency. Change the current vehicle cleaning process, customer and management end and cleaning side independent of each other. The design realizes the vehicle cleaning unmanned, automation. To reduce the cost of cost, reduce the volume of the system requirements. Finally, the key links of self-washing system are simulated and tested. It includes the algorithm simulation of motor operation control, the application test of image processing in wheel positioning, and the test of data exchange between mobile side app and cleaning side. The experimental results show that the research and design of the key technology of the self-service car washing system can meet the actual needs. This topic plays a certain role in the research and development of car washing field.
