【摘要】：2013年新交規(guī)首次明確提出客運(yùn)車內(nèi)的所有乘客均需佩戴安全帶，否則科以罰金。安全帶提醒裝置作為提高安全帶佩戴率的有效方法之一，每一個(gè)車輛均有安裝，但是現(xiàn)有安全帶提醒裝置的提醒對象僅僅指駕駛位和副駕駛位，而忽略了車內(nèi)后排乘客的提醒。對于客運(yùn)車而言，雖然有駕駛員以“喊話”的傳統(tǒng)方式提醒后排乘客佩戴安全帶，但每年的客運(yùn)車事故報(bào)告表明，總有部分乘客因未佩戴安全帶出現(xiàn)傷亡。因此，為了提高客運(yùn)車安全帶佩戴率，降低事故中因未佩戴安全帶造成的傷亡，本文提出了基于物聯(lián)網(wǎng)技術(shù)的客運(yùn)車乘客安全帶監(jiān)控系統(tǒng)。 1、理論研究：根據(jù)國內(nèi)外大量的文獻(xiàn)資料，總結(jié)已有的安全帶提醒裝置的手段和實(shí)現(xiàn)方法，以物聯(lián)網(wǎng)技術(shù)為基礎(chǔ)，提出相應(yīng)的研究內(nèi)容。同時(shí)，結(jié)合交管部門對于客運(yùn)車安全帶佩戴的要求、乘客未佩戴安全帶的原因，分析傳統(tǒng)客運(yùn)車安全帶提醒裝置的不足，提出客運(yùn)車安全帶監(jiān)控系統(tǒng)所應(yīng)解決的關(guān)鍵問題。 2、系統(tǒng)總體設(shè)計(jì)和實(shí)現(xiàn)：根據(jù)系統(tǒng)功能分析，對客運(yùn)車乘客安全帶監(jiān)控系統(tǒng)進(jìn)行總體設(shè)計(jì)，，包括系統(tǒng)總體結(jié)構(gòu)設(shè)計(jì)、系統(tǒng)的傳感器節(jié)點(diǎn)組網(wǎng)方案設(shè)計(jì)、系統(tǒng)的軟硬件設(shè)計(jì)、系統(tǒng)的低功耗設(shè)計(jì)、系統(tǒng)的通信協(xié)議設(shè)計(jì)和系統(tǒng)后臺數(shù)據(jù)庫設(shè)計(jì)。根據(jù)系統(tǒng)總體設(shè)計(jì)要求，完成了客運(yùn)車集中控制器和客運(yùn)中心監(jiān)控端的實(shí)現(xiàn)。其中，客運(yùn)車集中控制器是在嵌入式實(shí)時(shí)操作系統(tǒng)μC/OS-Ⅱ的平臺上進(jìn)行實(shí)現(xiàn)的；客運(yùn)中心監(jiān)控端是在VC++6.0平臺下采用MFC進(jìn)行實(shí)現(xiàn)的。客運(yùn)車集中控制器的實(shí)現(xiàn)是在無線網(wǎng)絡(luò)環(huán)境下，通過查詢指令對座椅節(jié)點(diǎn)進(jìn)行數(shù)據(jù)采集和傳輸，最后客運(yùn)車集中控制器通過網(wǎng)絡(luò)GPRS模塊將座椅數(shù)據(jù)傳輸給客運(yùn)中心監(jiān)控端；客運(yùn)中心監(jiān)控端程序?qū)崿F(xiàn)的是客運(yùn)中心管理人員的用戶登錄、運(yùn)行車輛內(nèi)部安全帶佩戴情況的實(shí)時(shí)監(jiān)控、后臺SQL數(shù)據(jù)庫的操作和數(shù)據(jù)報(bào)表的導(dǎo)出等。 3、系統(tǒng)測試：一，由于基于物聯(lián)網(wǎng)的客運(yùn)車的客運(yùn)車監(jiān)控系統(tǒng)的節(jié)點(diǎn)多，數(shù)據(jù)傳輸均建在無線傳輸?shù)幕A(chǔ)上，必須保證所設(shè)計(jì)通信模塊的功能屬性，即傳輸實(shí)時(shí)性、傳輸距離、數(shù)據(jù)丟包率等，通過在多種環(huán)境下的測試與分析，測試并驗(yàn)證通信模塊的性能；二，本文對系統(tǒng)的主要功能進(jìn)行了試驗(yàn)驗(yàn)證，即安全帶實(shí)時(shí)顯示功能，結(jié)果表明本系統(tǒng)滿足項(xiàng)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. The centralized controller of passenger vehicle is implemented on the platform of embedded real-time operating system 渭 C / OS- 鈪
