【摘要】：近年来,随着经济的飞速发展和人民生活水平的不断提高,我国机动车的数量逐年大幅增加,为了缓解交通压力,倡导自行车出行运用而生(1),公共自行车进入了城市公共交通工具的行列,成为新兴的城镇交通工具,有效的缓解了交通堵塞的状况。CAN总线是一种可靠性高,开发简单的现场总线管理系统,也是目前各国比较流行的一种总线管理模式之一,由于其成本低、可靠性强在很多领域广泛应用。这种系统从本质上来说是一种对等网络的运行总线,传递信息简单快捷,通信方式灵活方便,基于CAN总线的自行车管理系统能够有效的解决社会租借方式,它的管理方式是由后台统一控制和管理。这篇文章主要通过CAN总线技术分析,得出一套结构设计合理的通信接口,便于自行车租借系统的管理。论文CAN总线自行车管理系统详细介绍了基于CAN总线方式下的自行车借车还车方案,该系统由后台管理中心,中控柜单元,和自行车锁止单元三个部分组成,主要叙述了从CAN总线应用下解决中控控制下的自行车借还系统。本文做的工作有以下四个内容:一对公共自行车管理系统的总体设计与实现做了介绍和说明。二对基于CAN总线的锁位系统的硬件和软件设计做了叙述,包括CAN总线的定义,CAN总线的介绍,CAN总线的通信步骤,三CAN总线协议的层次结构,报文格式,优先级等概念,以及自行车后台管理系统与服务器的通信协议。四对自行车锁位系统的调试与实现做了叙述,本文采用实地调查考察法,以实用为主,结合问题的实质,实地实践研究,从而得到结论,方法和具体路线。通过对具体CAN总线有足够的认识,由实际操作得出数据验证所用方法的正确性,最终实现目标。
[Abstract]:In recent years, with the rapid development of economy and the continuous improvement of people's living standards, the number of motor vehicles in China has increased greatly year by year. In order to alleviate the traffic pressure and advocate the use of bicycles (1), Public bicycle has entered the ranks of urban public transport, and has become a new urban means of transportation, which effectively alleviates the situation of traffic jams. Can bus is a kind of high reliability and simple field bus management system. It is also one of the most popular bus management modes in many countries. Because of its low cost and strong reliability, it is widely used in many fields. In essence, this system is a kind of peer-to-peer network running bus, which transmits information simply and quickly, and the communication mode is flexible and convenient. The bicycle management system based on CAN bus can effectively solve the social rental mode. Its management mode is controlled and managed by the background. Through the analysis of CAN bus technology, this paper obtains a set of communication interface with reasonable structure design, which is convenient for the management of bicycle rental system. This paper introduces the bicycle loan and return scheme based on CAN bus in detail. The system is composed of background management center, central control cabinet unit and bicycle lock unit. This paper mainly describes how to solve the bicycle loan and return system under the control of central control from the application of CAN bus. The work done in this paper has the following four contents: first, the overall design and implementation of the public bicycle management system are introduced and explained. Secondly, the hardware and software design of locking system based on CAN bus is described, including the definition of CAN bus, the introduction of CAN bus, the communication steps of CAN bus, the hierarchical structure of three can bus protocol, message format, priority and so on. And bicycle background management system and server communication protocol. The debugging and realization of bicycle lock system are described in this paper. in this paper, the field investigation and investigation method is adopted, which is mainly practical, combined with the essence of the problem, and the field practice is studied, so as to get the conclusion, method and concrete route. Through enough understanding of the specific CAN bus, the correctness of the method used to verify the data is obtained from the actual operation, and finally the goal is realized.
