【摘要】：2013年新交规首次明确提出客运车内的所有乘客均需佩戴安全带，否则科以罚金。安全带提醒装置作为提高安全带佩戴率的有效方法之一，每一个车辆均有安装，但是现有安全带提醒装置的提醒对象仅仅指驾驶位和副驾驶位，而忽略了车内后排乘客的提醒。对于客运车而言，虽然有驾驶员以“喊话”的传统方式提醒后排乘客佩戴安全带，但每年的客运车事故报告表明，总有部分乘客因未佩戴安全带出现伤亡。因此，为了提高客运车安全带佩戴率，降低事故中因未佩戴安全带造成的伤亡，本文提出了基于物联网技术的客运车乘客安全带监控系统。 1、理论研究：根据国内外大量的文献资料，总结已有的安全带提醒装置的手段和实现方法，以物联网技术为基础，提出相应的研究内容。同时，结合交管部门对于客运车安全带佩戴的要求、乘客未佩戴安全带的原因，分析传统客运车安全带提醒装置的不足，提出客运车安全带监控系统所应解决的关键问题。 2、系统总体设计和实现：根据系统功能分析，对客运车乘客安全带监控系统进行总体设计，，包括系统总体结构设计、系统的传感器节点组网方案设计、系统的软硬件设计、系统的低功耗设计、系统的通信协议设计和系统后台数据库设计。根据系统总体设计要求，完成了客运车集中控制器和客运中心监控端的实现。其中，客运车集中控制器是在嵌入式实时操作系统μC/OS-Ⅱ的平台上进行实现的；客运中心监控端是在VC++6.0平台下采用MFC进行实现的。客运车集中控制器的实现是在无线网络环境下，通过查询指令对座椅节点进行数据采集和传输，最后客运车集中控制器通过网络GPRS模块将座椅数据传输给客运中心监控端；客运中心监控端程序实现的是客运中心管理人员的用户登录、运行车辆内部安全带佩戴情况的实时监控、后台SQL数据库的操作和数据报表的导出等。 3、系统测试：一，由于基于物联网的客运车的客运车监控系统的节点多，数据传输均建在无线传输的基础上，必须保证所设计通信模块的功能属性，即传输实时性、传输距离、数据丢包率等，通过在多种环境下的测试与分析，测试并验证通信模块的性能；二，本文对系统的主要功能进行了试验验证，即安全带实时显示功能，结果表明本系统满足项目的要求。
[Abstract]:In 2013, the new traffic regulations made it clear for the first time that all passengers in passenger cars must wear seat belts, otherwise they would be fined. As one of the effective methods to improve the wearing rate of seat belt, every vehicle is equipped with seat belt warning device, but the warning object of the existing safety belt warning device only refers to the driving position and the co-pilot position, but neglects the warning of the passengers in the rear row of the vehicle. For passenger cars, although drivers have traditionally warned back passengers to wear seat belts, the annual reports of passenger vehicle accidents show that some passengers are killed or injured because they are not wearing seat belts. Therefore, in order to increase the wearing rate of passenger vehicle seat belts and reduce the casualties caused by the failure to wear seat belts in accidents, This paper presents a passenger seat belt monitoring system based on Internet of things technology. 1. Theoretical study: according to a large number of literature at home and abroad, summed up the existing means and methods of safety belt warning device, Based on the Internet of things technology, the corresponding research contents are put forward. At the same time, according to the requirements of traffic control departments for passenger vehicle seat belts, and the reasons why passengers do not wear seat belts, this paper analyzes the shortcomings of the traditional passenger vehicle seat belt warning devices. The key problems of passenger vehicle seat belt monitoring system are put forward. 2, the overall design and implementation of the system: according to the system function analysis, the overall design of passenger seat belt monitoring system is carried out, including the overall structure design of the system. The design of sensor node networking scheme, hardware and software design, low power consumption design, communication protocol design and background database design of the system. According to the overall design requirements of the system, the realization of the centralized controller of passenger vehicle and the monitoring terminal of passenger transportation center is completed.
