Design And Implementation Of Intelligentized Parking Guidance System Based On Android Platform

In recent years,with the continuous growth of domestic car ownership and parking spaces in the owner's demand,parking difficulty has become one of the main problems which hinder the urban intelligent transportation system.The traditional vehicle guidance system is mostly based on vehicle navigation equipment,and the owner can only be guided near the entrance of the parking lot;in addition,drivers waste too much precious time in the low flow and disorderly looking for parking spaces and easily strayed into a dead end with no free parking.The above situation not only increases the road congestion inside the parking lot,but also leads to the confusion of parking management,low parking efficiency and bad parking experience.In order to solve these problems above,this paper independently designs and implements an kind of intelligent parking lot guidance system based on Android platform,builds using Ngnix load balancing cloud server,design a set of data structure,service interface and communication protocol,so the real-time and accurate data source can be provided for the guidance system.The basic data of the parking lot comes from the magnetic flux sendor controlled by AMR7,which dynamically detects parking spaces and route information of the parking lot,by the custom PP protocol,it can be shared into the database of the Tomcat server in real time.Independently we design and develop an Android parking guidance software based on the integrated development environment consist of the tools like Eclipse,Android SDK?JDK?ADT by using the language of Java.This software has friendly man-machine interface,the registration/login function,parking lot location query/search function,inside/outside navigation function of parking lot,reservation function of parking space,checkout and quick recharge function based on Alipay,provides one-stop service for the car owners,and makes parking no more difficult.The application is deployed on the Android OS,tested by the mainstream domestic brands like MI,HUAWEI,ZTE and the Mobile TestingCenter(MTC)of Baidu.The test results show that the software system completes the desired function,and has a great reference value for the research of the navigation area in the parking lot.In addition,the software is easy to operate,cost-effective,good compatibility,with a large practical and commercial promotion value.
