【摘要】：隨著公共交通系統(tǒng)的不斷發(fā)展和私家車的擁有量爆發(fā)式的增長,路面車輛的擁堵狀況越來越嚴重,特別是上下班高峰期,給人們的日常出行帶來了很大的阻礙,而由于機動車的尾氣排放帶來的空氣污染則嚴重影響了社會的可持續(xù)發(fā)展。低碳環(huán)保安全的短途旅行,受到越來越多人的認可與關(guān)注,將自行車融入到公共交通系統(tǒng)中,作為城市交通短途出行的補充與完善是世界各國交通發(fā)展的重要方向。本文研究工作依托實際開發(fā)項目,設(shè)計一套完整能獨立運行的公共自行車系統(tǒng),通過對現(xiàn)有公共自行車系統(tǒng)中的站點控制器、電子防盜鎖的功能改進與開發(fā),借助CPU卡的高安全性,設(shè)計完成了一套更加高效安全的公共自行車系統(tǒng),并在單個站點間完成了實際實驗測試。首先,本文研究了現(xiàn)有公共自行車系統(tǒng)的發(fā)展歷史和國內(nèi)外現(xiàn)狀,并總結(jié)匯總了現(xiàn)有公共自行車系統(tǒng)中存在的問題,針對這些問題提出了本文系統(tǒng)的研究目的與研究內(nèi)容。其次,本文簡述了基于CPU卡的公共自行車系統(tǒng)的設(shè)計需求與設(shè)計原則,并講解了本設(shè)計中CPU卡的基本技術(shù)規(guī)范。通過對系統(tǒng)中的租賃卡和系統(tǒng)傳輸總線更改的重要性的說明,提出了本文的系統(tǒng)設(shè)計方案,并對雙CPU卡結(jié)構(gòu)進行了講解介紹。再次,通過對全新設(shè)計的電子防盜鎖軟硬件條件的設(shè)計分析講解,介紹了本文設(shè)計系統(tǒng)的基本組成部分和基本工作原理。本文采用了雙CPU卡作為用戶租賃卡和自行車鑰匙卡,提高了系統(tǒng)和用戶的安全性,采用CAN總線完整站點數(shù)據(jù)傳輸,提高了系統(tǒng)的數(shù)據(jù)傳輸效率和穩(wěn)定性,并以STM32為核心控制器完成電子防盜鎖開發(fā),主要包括CPU卡讀卡器設(shè)計,智能電機驅(qū)動、CAN總線數(shù)據(jù)傳輸、語音及液晶控制等軟硬件開發(fā)調(diào)試。根據(jù)更改后的電子防盜鎖設(shè)計完善了站點控制器開發(fā),并在最后對設(shè)計的系統(tǒng)進行了設(shè)計調(diào)試,對設(shè)計過程和成果進行了展示,并完成了單個站點間的自行車租賃調(diào)試。本文設(shè)計的系統(tǒng)在一定程度上解決了現(xiàn)有公共自行車系統(tǒng)存在的安全性穩(wěn)定性問題,提高可運行效率,具有良好的實際運用和借鑒價值。
[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.
