针对大城市日益严重的停车难问题,本文设计并实现了一种基于无线传感器网络的智能停车诱导系统,以帮助用户快速找到合适的停车位.本系统采用无线地磁节点监测停车位状态,并通过无线传感器网络与有线局域网相结合的方式进行数据传输.为了满足停车场应用场景的低功耗要求,提出一种基于汇聚树协议(Collection Tree Protocol)的路由协议P-CTP,用以最小化无线传感器网络数据传输的能量消耗,提高系统的生存周期,并保证无线数据传输的可靠性.本文描述了系统的整体架构,并对监测模块的软硬件实现及P-CTP协议的原理与实现进行了详细介绍与分析,通过原型系统实验,评估了系统的能量消耗、丢包率和网络延时等.实验结果表明,系统性能能够满足停车场应用的需求.
In view of the increasingly serious parking problem in big cities, this paper designs and implements an intelligent parking guidance system based on wireless sensor networks to help users find a suitable parking space quickly.This system uses wireless geomagnetic node to monitor the status of parking spaces, and through Wireless sensor networks and wired LAN.In order to meet the low power consumption requirements of parking scenarios, this paper proposes a P-CTP routing protocol based on the collection tree protocol to minimize the wireless Sensor network data transmission energy consumption and improve the life cycle of the system and ensure the reliability of wireless data transmission.This paper describes the overall architecture of the system and the software and hardware implementation of the monitoring module and the principle and implementation of the P-CTP protocol Detailed introduction and analysis, through the prototype system experiment, the system energy consumption, packet loss rate and network delay are evaluated.The experimental results show that the system performance can meet the needs of parking lot applications.
