Design And Implementation Of O2O Multimedia Advertising Grab System Based On IOS

The traditional commercial advertising mode has been carried out by agency companies and media companies,and there is a serious information asymmetry.Therefore,the interests of the advertisers are damaged,and the idle household electronic screen and small business electronic screen can not be fully utilized.In order to solve the problems existing in the traditional advertising model,this paper creates a new advertising model based on 020.This new advertising mode integrates offline large screen resources and establishes online platforms for advertisers and equipment owners.This paper designs a 020 multimedia grab system.Through the two iOS mobile clients and servers,the system establishes a perfect network business platform.It makes full use of idle large screen and eliminates the disadvantages of traditional advertising mode to achieve fast and accurate advertising.This paper gives a detailed description of the system from the overall design and implementation details.According to the functional requirements of the system and the investigation and analysis of the mainstream framework,the overall architecture of the client is designed.The overall architecture consists of four layers:view layer,business logic control layer,storage layer and network layer.This paper introduces the key classes of two core modules.The advertising module uses the method of piecewise upload to resume inventory resuming.Order management module achieves real-time push orders by client and server long connection.The server also adopts a hierarchical architecture to separate the interface layer,logical layer and data layer.The server follows the RESTful interface specification for interface design.Play framework is used to develop the logic layer and MySQL is used to implement the local database.In this paper,the budget peacing algorithm is improved,and PPA(Price Pacing Algorithm)based on the time period,the area and the state of the competition is proposed.The paper also analyzes the adverse effects of RMS(Random Matchmaking Strategy)on the screen utilization.According to the minimum fragmentation principle in the idle period,MFMS(Minimum Fragmentation Matchmaking Strategy)is designed.The test results show that by using PPA the average success rate of order transaction is increased by 20.4%and the screen utilization ratio is increased by 9.6%.Though using the MFMS,the matching failure rate is reduced by 20%.
