【摘要】：随着公共交通系统的不断发展和私家车的拥有量爆发式的增长,路面车辆的拥堵状况越来越严重,特别是上下班高峰期,给人们的日常出行带来了很大的阻碍,而由于机动车的尾气排放带来的空气污染则严重影响了社会的可持续发展。低碳环保安全的短途旅行,受到越来越多人的认可与关注,将自行车融入到公共交通系统中,作为城市交通短途出行的补充与完善是世界各国交通发展的重要方向。本文研究工作依托实际开发项目,设计一套完整能独立运行的公共自行车系统,通过对现有公共自行车系统中的站点控制器、电子防盗锁的功能改进与开发,借助CPU卡的高安全性,设计完成了一套更加高效安全的公共自行车系统,并在单个站点间完成了实际实验测试。首先,本文研究了现有公共自行车系统的发展历史和国内外现状,并总结汇总了现有公共自行车系统中存在的问题,针对这些问题提出了本文系统的研究目的与研究内容。其次,本文简述了基于CPU卡的公共自行车系统的设计需求与设计原则,并讲解了本设计中CPU卡的基本技术规范。通过对系统中的租赁卡和系统传输总线更改的重要性的说明,提出了本文的系统设计方案,并对双CPU卡结构进行了讲解介绍。再次,通过对全新设计的电子防盗锁软硬件条件的设计分析讲解,介绍了本文设计系统的基本组成部分和基本工作原理。本文采用了双CPU卡作为用户租赁卡和自行车钥匙卡,提高了系统和用户的安全性,采用CAN总线完整站点数据传输,提高了系统的数据传输效率和稳定性,并以STM32为核心控制器完成电子防盗锁开发,主要包括CPU卡读卡器设计,智能电机驱动、CAN总线数据传输、语音及液晶控制等软硬件开发调试。根据更改后的电子防盗锁设计完善了站点控制器开发,并在最后对设计的系统进行了设计调试,对设计过程和成果进行了展示,并完成了单个站点间的自行车租赁调试。本文设计的系统在一定程度上解决了现有公共自行车系统存在的安全性稳定性问题,提高可运行效率,具有良好的实际运用和借鉴价值。
[Abstract]:With the continuous development of the public transportation system and the explosive increase of private car ownership, the traffic congestion on the road is becoming more and more serious, especially during the rush hour, which brings great obstacles to people's daily travel. The air pollution caused by the exhaust emission of motor vehicles has seriously affected the sustainable development of society. Low-carbon environmental protection and safety short-distance travel has been recognized and paid more and more attention by more and more people. It is an important direction of transportation development all over the world to integrate bicycle into public transportation system as a supplement and perfection of urban short-haul transportation. Based on the actual development project, this paper designs a complete public bicycle system which can run independently. Through the improvement and development of the function of electronic anti-theft lock in the existing public bicycle system, With the help of the high security of CPU card, a more efficient and safe public bicycle system is designed and tested in a single site. First of all, this paper studies the development history of the existing public bicycle system and the current situation at home and abroad, and summarizes the existing problems in the existing public bicycle system, and puts forward the purpose and research content of this paper. Secondly, this paper briefly describes the design requirements and design principles of the public bicycle system based on CPU card, and explains the basic technical specifications of the CPU card in this design. Based on the explanation of the importance of the change of the rental card and the system transmission bus in the system, the design scheme of the system is put forward, and the structure of the double CPU card is introduced. Thirdly, the basic components and working principles of this design system are introduced by analyzing and explaining the hardware and software conditions of the new electronic anti-theft lock. In this paper, the double CPU card is used as the user rental card and the bicycle key card to improve the security of the system and the user. The CAN bus is used to complete the station data transmission, and the data transmission efficiency and stability of the system are improved. The development of electronic anti-theft lock is completed with STM32 as the core controller, including the design of CPU card reader, intelligent motor drive, CAN bus data transmission, voice and liquid crystal control and so on. According to the modified electronic anti-theft lock design, the development of the site controller is perfected. At last, the system is designed and debugged, the design process and results are displayed, and the bicycle leasing debugging between individual sites is completed. To a certain extent, the system designed in this paper solves the problem of safety and stability existing in the existing public bicycle system, improves the operational efficiency, and has good practical application and reference value.
