智能车位预定与场内停车导航系统的设计与开发

The design and development of intelligent parking reservationand parking guidance system

针对城市"停车难"问题以及现有停车诱导系统的不足,文章提出一种基于BDS+INS技术的室内停车系统,该系统主要由停车场子系统、云端数据实时收发平台、用户子系统三部分构成,并以无线网络作为数据传输媒介,将三部分紧密联系起来。其中停车场子系统中视频检测器检测停车场信息,作为系统数据基础;云端数据实时收发平台主要与停车场子系统、用户子系统进行数据交换和存储;用户通过交互界面可完成车位信息实时查看、车位预订、车位导航、反向寻车导航以及快速缴费等功能。由于在地下停车场内无法获取卫星信号,所以目前所普遍使用的停车系统未能进行室内停车场精确的车位引导,因此本系统创新应用了北斗+惯性(BDS+INS)组合导航系统,通过综合各传感器参数,保证系统在地下多层停车场内,也能进行一定时间内高精度的车位导航。目前,经过实验,本系统基本功能已能实现。在未来大规模使用本系统,不但能提高停车场资源使用效率,还可极大程度改善城市静态交通的问题。

This paper presents an indoor parking system based on BDS＋INS technology for the problem of ＂parking difficulty＂ in cities and the shortage of existing parking guidance system.The system consists of three parts ：the parking subsystem,the cloud data real-time receiving and sending platform,and the user subsystem.And the wireless network as the data transmission medium,the three parts are closely related.In the parking subsystem,video detector detects car for parking information as the basis of system data.The cloud data real-time platform mainly deals with the parking subsystem and user subsystem for data exchange and storage;Through interactive interface,the user can complete the real-time view of parking information,berth reservation,parking navigation,search berth navigation and fast payment.Because of inability to obtain satellite signals in the underground parking,the commonly used parking system has not been able to conduct accurate parking guidance for the indoor berth.Therefore,the system innovates the integrated navigation system of BDS＋INS.By synthesizing the parameters of each sensor,the system can be used in the underground multi-storey car park.At present,the basic functions of the system have been realized through experiments.In the future,large-scale useing of this system will not only improve the efficiency of parking resources,but also greatly perfect the static urban traffic problems.
