CAN Bus Public Bicycle System Research And Application

In recent years, with the rapid economic development and improve people's living standards, the number of motor vehicles increased significantly year after year, in order to ease traffic pressure, promote the use of bicycles and health, public bicycle into the ranks of the city become the new type of vehicle urban transport, effectively easing the traffic jams. CAN bus is a high reliability, to develop a simple public bike-site management system, is currently one of the more popular countries to a management model, due to its low cost and reliability are widely used in many fields. This system is a peer to peer network bus running from the essence, simple and quick transmission of information, communication flexibility, based on CAN bus bike management system can effectively solve social lease management approach is the way it can be controlled by the background and management. This article by CAN bus technology analysis, the rational design of a structured communication interface, easy to manage bike systems. Thesis management system CAN bus bike bicycle detail based on CAN bus under way to borrow the car the car program, which consists of three parts backstage management center, in control cabinet unit, and bike lock unit, which mainly describes the CAN bus solve bike under control by the central control system application also lower. This paper has done the following four elements: a pair of the overall design and implementation of public bicycle management systems have been described and illustrated. Second, the hardware and software based on CAN bus system design latches do narrative, including the definition of CAN bus, introduces CAN bus, CAN bus communication procedure. Layer structure of three CAN bus protocol, message format, and priority concepts and communication protocols bike back office systems and servers. Commissioning and achieve four bicycle lock-bit systems do narrative. In this paper, the field survey study law, be practical, with substantive issues, practical research in the field, resulting in the conclusion, methods and specific routes. Through the concrete can bus has sufficient knowledge derived by the actual operating data to verify the correctness of the method used, the ultimate goal.
