WiFi Wireless Intelligent Parking System

Recently,with the rapid economic development and industrial structure adjustment, the urban population is gradually increasing,people’s living standards gradually improved, making China’s car ownership is growing.According to statistics, China has become the world’s largest auto market with 40% annual growth rate.At the same time becoming more frequent business economy also makes the logistics industry grow rapidly, so traffic jam is commonly seen now.Although China’s development in the technical aspects of parking management system started late, compared to abroad there is a large gap.But on a serious rush hour traffic jam, vehicles entering and leaving residential, office buildings and other parking queuing phenomenon has caused widespread concern in the community.Parking is no complete set of traditional information management and publishing system, making the owners are looking yard and parking on spending a lot of time;And in the tradition of parking charges and management there are many drawbacks.In order to improve the efficiency of the parking lot, to improve its management fees, the paper proposes an intelligent parking system wireless Guidelines.The intelligent parking system uses self-organizing wireless network technology eliminates the complex field wiring to solve the owners own a waste of time to find spare parking problems and improve the parking without navigation system defects, to achieve a collection of free parking information, publishing, and enter the vehicle to achieve navigation, billing and other functions, and the use of existing networks reduce engineering costs.Based on WIFI technology embedded wireless gateway, and Android-based mobile client designed a smart parking system wireless guidelines.The system integrates information collection, display, communicationfunctions in one, by the sensor terminal nodes, the nodes scene shows several parts, the central controller and the Internet and other components.Sensor terminal node is responsible for parking at the top of the collected information is sent via wireless or without parking sensor system out summary information after the central processing unit can be controlled via the LCD display screen shows the current node status,respectively, data entry can also SD card or through the GPRS network to facilitate the inquiry record.This article focuses on the hardware design and software design of the system hardware circuit design WIFI network each node, fully reflects the low-cost, low-power design. Combined with the upgrade of existing parking demand, the implementation of this project has a certain value.
