| With the rapid development of enconomy and the progress of urbanization,chinese automobile ownership increased yearly and parking problem has bean more and more prominent.Although the main reasons of parking problem is lack of the number of parking spaces,but the free spaces are not fully utilized(especially the private spaces).In addition to build new parking spaces,it is worth thinking about how to use the free spaces as possible as we can.This paper do research around a smart app of the smart parking spaces that is based the parking lock self-organizing network,which using the Zigbee technology and ModBus communication protocol.To build a smart parking system which is oriented the mobile app,which use the mobile app technology、the server developing technology and Zigbee technology,which main point are systemic、smart and steady.The system is to aim at realizing the automatism manage and the owner of the private spaces could rent their spaces effectively which takes advantage of the ZigBee technology at buildings.The paper’s aims to share their parking spaces and to solve the problem of parking.There are the main research contents.First,this paper summarizes the key development techniques of intelligent parking control system such as wireless communication technology 、 database management technology and mobile app development.Second,to analyze the demand of the smart parking spaces system which is oriented object mobile.After that,to get the user-case diagram and function module diagrams.At the same time,to design the technical architecture with “Express + MongoDB + NodeJS’ for the system.Then designing the database which is around the architecture and features of the system.And to draw out the E-R diagram and the data flow diagram.After that,to design the controlling software、the networking mode of the parking sapces.To design the data format and function which is based ZigBee.Then to develop the server which is based Express.And to build the way of the data about managing and communicating.Then,to design the server API format which is based REST.And designing the app functions and the user interface.To determine the structure of the parking lock.Finally,to realize the device API and the user API that based the REST,which use the Express framework、MongoDB database and NodeJS platform in server which is based the component-oriented.To establish the app in Java at the Android Studio.There are the smart parking system which is based the mobile-oriented.The result shows that the system can complete all functions under designing and testing. |
