The Design And Implementation Of Hardware-software In Parking Lot's Data Transmission System

Our country has become the first car producer and consumer,for the people,driving has become a main way to travel.With the development of automobile industry,parking charge system is also in rapid development,which has applied to the most part of parking lot.At present,there are two problems in mainstream parking system in terms of data security:firstly,parking data and financial data is stored in the local computer or server of parking lot,it failed to transfer to the fund management department real-timely and meet the needs of the modern enterprise in financial management.Secondly,there is the risk of moral hazard,if the relevant staff of parking lot modify the corresponding data,it can cause the capital loss of the fund management department.In order to solve the problems above,this paper integrates contemporary preface technology,such as the internet,4g data transmission,database,web production,and then proposes a data transmission system for mainstream parking lot.Firstly,on the basis of analyzing the logical relations of many forms in the database,this paper deeply research the mainstream server software system adopted in the intelligent parking lot,and then establishes a dynamic financial database.After that,this system designs the software module of financial data transmission,while the data transmission is based on wired,this system designs the background data processing module by using C#programming language and also using the web service technology to design the data transmission interface.If data transmission is based on the wireless,the system is achieved by using SIM7100C chip as the core of the 4g data transmission module,the financial data information extraction and data receiving module are developed by using the data extraction protocol.The data extraction protocol are developed in C#programming language,the system achieves the data transmission,which is sending financial data of parking lot to the remote cloud server by the two ways of wired and wireless.Finally,this paper designs the computer version and mobile device version of data statistics system at the data receiving end of parking lot.Through a large number of actual test show that parking lot's data transmission system based on hardware and software for data remote transmission can realize real-time and fast transmission of large amount of parking lot's data by using wired and wireless networks.And according to user's query requirements to achieve the corresponding data information query and statistics of parking lots.It can provide the convenience to analyze the parking lot's operations and charge information statistics for parking management in real-time.At the same time,It is possible to prevent the parking lot's data information from being modified.
