【正文】 自動洗車機(jī) 的 PLC系統(tǒng)設(shè)計 I 基于 自動洗車機(jī)的 PLC 系統(tǒng) 的設(shè)計 摘 要 隨著我國汽車保有量的迅速提高，汽車清洗行業(yè)迎來了一個重要的發(fā)展機(jī)遇，自 動 洗車機(jī)作為洗車工作必不可少的設(shè)備，其清洗效果，清洗速度，清洗成本以及對節(jié)水和環(huán)境保護(hù)的要求，成為其開發(fā)和生產(chǎn)必須要考慮的內(nèi)容。 本文主要通過對 自動 洗車機(jī)功能要求和運(yùn)行過程的分析，確定了自動洗車機(jī)的總體設(shè)計方案。主要進(jìn)行了自 動 洗車機(jī)的驅(qū)動和控制系統(tǒng)的設(shè)計，針對自 動 洗車機(jī)的特點(diǎn)，采用噴水，洗刷，噴灑清洗劑和風(fēng)干等過程，在控制部分，應(yīng)用傳感器和可編程序控制器技術(shù)，對汽車清洗機(jī) PLC 控制系統(tǒng)進(jìn)行了硬件設(shè) 計和控制軟件編程。 PLC 選用三菱公司生產(chǎn)的 FX2N系列可編程序控制器，采用梯形圖編程語言，實(shí)現(xiàn)了汽車清洗機(jī)的傳動和控制要求，滿足了環(huán)保、高效、可靠和低成本的要求。 關(guān)鍵詞： 自動洗車機(jī)， PLC， 控制系統(tǒng) ，梯形圖，硬件及軟件 自動洗車機(jī) 的 PLC系統(tǒng)設(shè)計 II Management System For automatic car washing machine ABSTRACT As the amount of car increases very quickly, the service trades of car are facing a very important chance. Because Car washer is the most important equipment in the process of washing car, these questions must be reflected on in the process of the design and the manufacture of the automatic car washer, such as the effect of washing car, the efficiency of washing car, the cost of washing car, the protect of environment, and so on. In this side, according to the analysis of the function and the operating process of car washer, the overall plan of design is determined． The detail design of the driving and controlling system of car washer are designed, according to the characteristics of the automatic car, it adopts some processes, such as the vaginal spray, spray cleaning agent, brushing, air drying and so on. In the control system， it adopts the technology of sensor and PLC to design the position of PLC hardware and program the controlling software． The controller is Mitsubishi FX2N series PLC and the program is ladder program, it meets the requirements of the operating and controlling and also the demands of the efficiency, the cost and protect of the environment.
