技术领域technical field

本发明属于汽车电子监测技术领域，涉及一种基于移动通信方式的汽车车况智能监测系统，是电子、信息、计算机技术结合的产物。The invention belongs to the technical field of automobile electronic monitoring, relates to a mobile communication-based intelligent automobile condition monitoring system, and is a product of the combination of electronics, information and computer technologies.

背景技术Background technique

近年来，随着电子通信理论和技术的进步，移动通信、计算机技术以及汽车电子技术得到迅速发展，以此又带动了城市交通管理系统的革命性更新。高速蜂窝无线通信技术可以满足未来无线通信的语音、数据以及多媒体应用等各种高速率高性能的需求，汽车电子技术则是现代汽车工业与电子技术相结合的产物。In recent years, with the advancement of electronic communication theory and technology, mobile communication, computer technology and automotive electronic technology have developed rapidly, which has led to the revolutionary update of urban traffic management systems. High-speed cellular wireless communication technology can meet various high-speed and high-performance requirements for future wireless communication such as voice, data and multimedia applications. Automotive electronic technology is the product of the combination of modern automotive industry and electronic technology.

车况监测是车辆交通管理工作的一项重要内容，也是及早发现隐患、杜绝违章、防止事故的重要手段。目前国内外的车况监测系统，例如传统的有油量表、里程纪录仪、速度指示仪表等，近年来电子技术的发展，新增有电子传感器件。电子传感器件的功能和质量虽然有所改善，但基本上仍处于单纯的机械-电子技术的组合应用中。这种监测系统的自动化程度不高，往往需要驾驶者、车辆维护人员和交通警察投入相当多的时间和人力执行观察、纪录、判断等琐碎工作。其次，由于人工作业的低效率和分散性，无法应对随着经济发展而迅速增长的上路汽车数量，大部分车辆的车况信息也没有集中备案和集中管理，处于零散分布的状态，只能在平时由车主自己掌握，交通监管部门也只有在年审车况或者因车况问题发生事故时才能掌握该车的车况。此外，这种监测系统由于不能同交通监管部门实时交换数据，所以不能对交通监管部门所辖整个道路交通网中的所有车辆进行实时监控，不能及早防止超重、超速、超载等违章驾驶状况，也不能及早发现有车况隐患的车辆上路行驶，同时，不能及时地对各上路汽车发送指令和指导。Vehicle condition monitoring is an important part of vehicle traffic management work, and it is also an important means of early detection of hidden dangers, elimination of violations, and prevention of accidents. At present, vehicle condition monitoring systems at home and abroad, such as traditional fuel gauges, mileage recorders, speed indicating instruments, etc., have been newly added with electronic sensor devices due to the development of electronic technology in recent years. Although the function and quality of electronic sensor devices have been improved, they are basically still in the combined application of pure mechanical-electronic technology. The degree of automation of this monitoring system is not high, often requiring drivers, vehicle maintenance personnel and traffic police to invest a considerable amount of time and manpower to perform trivial tasks such as observation, recording, and judgment. Secondly, due to the low efficiency and dispersion of manual work, it is impossible to cope with the rapid increase in the number of vehicles on the road with economic development. It is usually controlled by the car owner himself, and the traffic supervision department can only grasp the condition of the car when the condition of the vehicle is inspected annually or when an accident occurs due to a problem with the condition of the vehicle. In addition, since this kind of monitoring system cannot exchange data with the traffic supervision department in real time, it cannot monitor all vehicles in the entire road traffic network under the jurisdiction of the traffic supervision department in real time, and cannot prevent overweight, speeding, overloading and other illegal driving conditions as early as possible. It is impossible to find out that vehicles with hidden dangers in vehicle conditions are driving on the road, and at the same time, instructions and guidance cannot be sent to each vehicle on the road in time.
