基于无线自组网络的车位检测系统设计

Design of parking space detection system based on wireless ad hoc network

随着我国经济的快速发展,汽车的使用量在高速增长,但大型停车场目前安装的引导泊车系统存在只显示全部车位数量,成本高,停车效率低等问题。因此提出了一种基于无线自组网络的大型停车场空闲车位检测方法并设计了相应的检测系统。该系统首先将大型停车场进行分区管理,将每个分区设计为系统的一个节点,所有节点都安装一个无线通信控制模块,模块之间通过无线自组网络进行通信。每个模块功能主要包括:检测对应区域的空闲车位数量、数据无线分发给其余模块、显示所有分区的空闲车位数量和分区方向。该系统在优化车位数量检测与显示的同时,大大减少物理布线,进一步完善了停车场内部引导功能,避免停车场产生拥堵,提高空闲车位查找效率,对大型停车场的智能化改造具有重要的参考价值。

with the rapid development of China's economy,the use of cars is growing rapidly,but the guided parking system installed in large parking lots only displays the number of all parking spaces,high cost and low parking efficiency.Therefore,this paper proposes an idle parking space detection method of large parking lot based on wireless ad hoc network,and designs the corresponding detection system.Firstly,the system manages the large parking lot by zones,and each zone is designed as a node of the system.All nodes are equipped with a wireless communication control module,and the modules communicate through wireless ad hoc network.The functions of each module mainly include:detecting the number of free parking spaces in the corresponding area,wirelessly distributing data to other modules,and displaying the number of free parking spaces and partition direction in all partitions.While optimizing the detection and display of the number of parking spaces,the system greatly reduces the physical wiring,further improves the internal guidance function of the parking lot,avoids congestion in the parking lot,improves the search efficiency of idle parking spaces,and has an important reference value for the intelligent transformation of large parking lots.
