平板式汽车制动智能检测系统的开发

摘      要

近几年，随着我国汽车工业的迅猛发展，汽车正逐渐进入家庭，成为生活的1部分。但交通事故频繁发生，在交通事故中，约有半数以上是由于汽车的制动性能不佳引起的，这给汽车制动性能检测技术的研究、检测设备及检测手段的更新和发展提出了新的课题。
    本文系统地研究了汽车制动系统的设计理论、设计方法，依据汽车制动性能检测相关法规，研究并开发出平板式汽车制动智能检测系统。该系统采用分布式管理方式，主控机采用PC机，数据采集系统采用MCS-51为中央处理器的单片机系统，主控机与数据采集系统之间通信联系采用RS-232串行口进行通信。系统软件共分PC机与单片机两大块，其中：单片机部分软件采用MCS-51汇编语言编写，PC部分采用Microsoft公司的 Microsoft Visual Basic 6.0应用程序开发工具设计的。该检测系统来源于汽车检测站的汽车制动性能年检设备综合化、智能化要求，主要用于交通管理部门对轿车进行年终检测时的制动力与轮轴重量（动态、静态）检测，该系统既可以成为1个独立的检测单元来使用，也可以通过主控机的数据库系统与整过检测站乃至全国各汽车检测站实现资源共享。

Abstract

In recent years, with the swift and violent development of automobile industry, the automobile is entering the families, and become a part of their life. But traffic accidents happen frequently, more than half of which are accused by the less efficiency of automobile’s brake performance. Therefore, it brings a new subject to the study of automobile’s brake performance test technology and the renewal and development of test equipments and methods. （科教范文网http://fw.ΝsΕΑc.com编辑）
This article gives a systematical study about the theory and methods of design automobile’s brake system. According to the correlative statute of the automobile’s brake performance tests, we developed a type of system software for the intelligent tabulate automobile’s brake intellective test device. The system adopts distributive management, PC is used as the master-control, and data collection system adopts MCS-51 as the CPU of the SCM （Single Chip Micyoco）. Using RS-232 to implement the communication between master-control and data collection system. In the system, the part of SCM is compiled with the language of MCS-51, and the software for master-control is compiled with the application tool, Microsoft Visual Basic 6.0 of Microsoft Company. The test system roots in the requirement of the devices’ integration and intelligence for annual automobile brake performance test in the test station, and is mainly applied to the annual test for the car’s brake force and the weight of axles (dynamic or static) by the traffic managerial apartment. The system can be used as a separated test unit, also shared by the whole test station through the database in master-control, even by the entire country.
