Design And Implementation Of Real-Time Distributing System Of Subway Advertisement Based On Spark

With the rapid development of subway transportation in major cities,more and more people choose to travel by subway.What followed was the advertising of various businesses in the subway.At present,subway advertisements are mainly based on static advertisements such as light boxes and carriage advertisements and LED screen dynamic advertisements.Among them,the LED screen dynamic advertisement adopts the loop broadcast,but the irregular distribution of the subway passenger flow will cause the audience of each advertisement under the same price to be unbalanced,which leads to the problem of the drop of the price of the dynamic advertisement position,making the advertisement The benefits are lower.This paper designs and implements a system that uses Spark real-time computing technology to control dynamic advertisement playback through changes in passenger flow to solve the above problems.The system combines a multi-gradient advertising price system with the gate billing system originally existing in the subway.When passengers swipe in and out of the station,the passenger flow information of each subway station is continuously transmitted to the big data real-time computing platform.Through the processing of data prepared in the real-time computing platform to process the data,the real-time traffic information of different subway stations is counted,and then sent to the ad-distribution system,thereby realizing dynamic switching of each subway station with real-time traffic.purpose.At the same time,the user can intuitively observe the different real-time changes of different advertisements and different stations on the day through the visual interface in the system,and can also export the historical information of the records to the EXCEL form,which facilitates subsequent analysis of the value contained therein.Not only that,the user can also enter the complete price system and advertisement information through the system interaction interface,which facilitates the management of advertisements that need to be placed.As a result,the real-time advertising of the subway will form a similar strategy to the placement of TV commercials,resulting in a “golden spot” time period,which will increase the intensity of competition in dynamic advertising and increase its overall efficiency.
