摘要由于城市居民的不断增加及大幅度使用汽车，导致城市交通拥挤，环境破坏问题越来越严重，大大的阻碍了我国城市交通的发展，因此政府倡导居民绿色环保出行。然而公共自行车正是具备这些优点，虽然骑行比较累，但是可以做到强身健体，同时也能给绿色社会贡献一点力量，公共自行车无需占用多大地方，可以让居民方便的自由骑行，做到真正意义上的环保。

在无线网络的基础下，联系城市公共自行车系统的特点，规划出设计的意义和目的，从而组建更完善的系统框图，并对各电路功能模块进行设计。电源模块、IC读卡器识别模块、车辆借还模块、LCD显示模块、时钟模块、警报处理模块、复位模块及无线网络模块等组成了城市公共自行车系统。70407

在城市公共自行车系统的硬件设计下，对其进行软件设计，对于各个模块进行流程图的分析及简单的代码分析。比如各种程序的构建、逻辑类的建立、电路模块设计的实现、数据通信和接口的实现等。最后对该系统进行总结和展望。

The Design Of City Public Bike System  Based On Wireless Network

Abstract

Due to the increasing number of urban residents and greatly use the car,lead to the congestion of country traffic ,environmental damage problem more and more serious,greatly hindered the development of urban traffic in China,so the government advocates the residents of pollution-free green travel.Public bicycle is have these advantages,however,although the ride is more tired,but you can do to keep fit,at the same time also can contribute to green society,public bicycle without occupy how much place,can let people convenient to ride freely,in the true sense of environmental protection.

Based on the wireless network,connected with the features of country public bicycle system,planning out the meaning and purpose of design,so as to form a more perfect system frame,function module design and for each circuit.Power supply module,IC card recognition module,the bikes’ borrowing and returning module,LCD display module,clock module,alarm processing module,the reset module and wireless network module form the public bicycle system.

Under the urban public bicycles of the system hardware design,software design,the analysis of the flow chart for each module and the analysis of the simple code.The establishment of the logic class,the realization of circuit module design,the communication of the date, and at the same time it realized the implementation of the   interface,etc.Finally,summary and prospect of the system.
