【摘要】：伴隨著公路運輸業(yè)的快速發(fā)展，近年來我國的交通運輸車輛超載現(xiàn)象極為的普遍，甚至幾乎所有大型運輸車輛都有著不同程度的超載行為，國家的相關(guān)部門與地方政府先后展開了一系列的整治工作，并取得一定成效。但由于超載的涉及面太廣，治理難度很大，加上利益上的驅(qū)動，使得超載現(xiàn)象愈發(fā)的嚴重。因此汽車衡的準確使用對于國家的運輸業(yè)的發(fā)展非常的重要。本文綜述了單片機基本原理及單片機控制系統(tǒng)的一般結(jié)構(gòu)和實現(xiàn)智能汽車衡稱重的實現(xiàn)方法，提出了基于單片機控制系統(tǒng)設(shè)計的原則、內(nèi)容和步驟。針對稱重過程，利用單片機進行數(shù)據(jù)的采集、處理和數(shù)據(jù)傳輸及攝像頭自動識別車牌，最終實現(xiàn)無人值守，智能的控制。 本設(shè)計首先介紹了有關(guān)衡器的基礎(chǔ)知識，系統(tǒng)的硬件應(yīng)用，隨后說明了汽車衡的結(jié)構(gòu)組成、工作原理及硬件電路的設(shè)計、軟件的仿真，最終完成了一套數(shù)字式電子汽車衡稱重系統(tǒng)的硬件和軟件設(shè)計的任務(wù)。設(shè)備的精度、可靠性、強度性、和防作弊性能有了很大的提高。 實驗利用Proteus進行單片機電路設(shè)計和仿真，利用KEILC51進行編程，利用Proteus進行電路圖的設(shè)計。本方案的設(shè)計，目的是設(shè)計一套智能的汽車衡測量系統(tǒng)，并使該系統(tǒng)能夠成為一個能夠利用計算機管理并進行通訊、自動控制集一身的智能化測量系統(tǒng)。它除了具有傳統(tǒng)的車中測量功能外，還需擁有能夠利用單一的通訊設(shè)備來對各種監(jiān)控設(shè)備進行控制。由此能夠為用戶提供快速、便捷、實用的測量系統(tǒng)。
[Abstract]:With the rapid development of highway transportation, the phenomenon of overloading of transportation vehicles in China is very common in recent years, even almost all large transport vehicles have different degrees of overload behavior. National departments and local governments have launched a series of rectification work, and achieved certain results. However, the overload phenomenon becomes more and more serious because of the wide range of overloading, the difficulty of governance and the drive of interest. Therefore, the accurate use of automobile scale is very important for the development of national transportation industry. This paper summarizes the basic principle of single chip microcomputer, the general structure of single chip microcomputer control system and the realization method of intelligent vehicle weighing, and puts forward the design principles, contents and steps of the control system based on single chip microcomputer. In view of weighing process, the single chip microcomputer is used to collect, process and transmit the data and recognize the license plate automatically by the camera. Finally, the unattended and intelligent control is realized. This design first introduces the basic knowledge of the weighing device, the hardware application of the system, and then explains the structure, working principle, hardware circuit design and software simulation of the automobile scale. Finally, the task of hardware and software design of a digital electronic truck weighing system is completed. The accuracy, reliability, strength, and anti-cheating performance of the equipment have been greatly improved. The experiment uses Proteus to design and simulate MCU circuit, KEILC51 to program and Proteus to design circuit diagram. The purpose of this scheme is to design an intelligent measuring system of automobile scale, and to make the system become an intelligent measurement system which can be managed by computer and controlled automatically. In addition to the traditional in-vehicle measurement function, it also needs to be able to use a single communication device to control various monitoring equipment. This can provide users with a fast, convenient, practical measurement system.
