【摘要】：互联网的不断普及和电子商务的飞速发展，使物流业在第三产业当中占据着越来越大的比重。车辆运输作为物流中主要的货运方式，对整个物流供应链的运作有着巨大的影响。然而在车辆运输的过程中，司机不按规定路线驾驶的行为给企业带来不小的经济损失。为了能监管车辆的行驶过程，企业需要对车辆进行实时的、远程的监控。现有的监控系统虽然能获取到车辆的位置和行驶路径，但是需要由监控人员进行查看分析。随着运营车辆的增多，这种模式不仅造成企业人力资源成本的增加，也耗费了监控人员大量的精力。在长距离运输的过程中，车辆不可避免会遇到交通事故。当事故比较严重时，司机往往会失去呼救能力，当出现这种情况现有的监控系统却无法得知，从而错过了最佳的救援时间。为了解决上述的问题，本文设计了一套开发成本低，扩展性好，可靠性高的运输车辆状态监管系统，该系统具有对车辆行驶路径及安全状态的自动检测及报警功能。另外，由车载终端自行进行状态检测、判断与报警的运行模式，改变了传统以监控人员对车辆进行监视和分析的模式，从而降低了人力资源成本，提高了系统的智能性。本论文以当前物流车辆运输存在的主要问题为项目背景，首先介绍了当前国内外物流运输的发展现状,然后分析了现有车辆监控系统的缺陷，接着对本系统需要实现的功能和目标进行了需求分析。文章分别从硬件和软件的方面对本系统的设计进行了论述，并通过实际的实验操作对本系统进行验证。系统的硬件设计主要从GSM/GPS芯片、单片机控制器、以及输入输出接口等方面进行论述。文中对系统各功能模块的实现原理和工作过程进行介绍，同时给出了部分核心电路图。系统软件主要阐述了状态检测、数据采集与发送和监控中心等部分的软件设计，给出了核心源代码并分析了其工作流程。系统设计完成后，通过实际试验测试，结果表明本文设计的运输车辆状态监管系统报警准确，，工作稳定。
[Abstract]:With the rapid development of the Internet and the rapid development of e - commerce , the logistics industry occupies an increasingly large proportion in the tertiary industry . In the process of vehicle transportation , the driver does not drive the whole logistics supply chain . In order to monitor the running process of the vehicle , the enterprise needs to monitor the whole logistics supply chain . In order to monitor the running process of the vehicle , the enterprise needs to monitor the vehicle in real time . In order to solve the above problems , the paper designs a system for monitoring the state of transportation vehicles with low development cost , good expansibility and high reliability . The system has automatic detection and alarm function for the vehicle running path and the safety state . In addition , the vehicle - mounted terminal automatically performs state detection , judgment and alarm operation mode , changes the traditional mode of monitoring and analyzing the vehicle by the monitoring personnel , thus reducing the human resource cost and improving the intelligence of the system . This paper introduces the current situation of logistics transportation at home and abroad , then analyzes the defects of the existing vehicle monitoring system , then analyzes the function and the target that the system needs to realize . The paper discusses the design of the system from the aspects of hardware and software , and verifies the system through actual experimental operation . The hardware design of the system is mainly discussed from the aspects of GSM / GPS chip , single chip controller and input / output interface . The realization principle and working process of each functional module of the system are introduced , and some core circuit diagrams are also given . The system software mainly expounds the software design of the state detection , data acquisition and transmission and monitoring center , and gives the core source code and analyzes its workflow . After the system design is completed , the actual test results show that the system designed in this paper is accurate in alarm and stable in operation .
