Application Of Coupled Distributed Computing Platform In Secondary Identification Of Automobile 4S Shop

Coupled distributed computing platform provides a reliable distributed platform for high-speed train-related distributed calculation problem.And the distributed platform can calculate the tasks about the high-speed train distributed-related now.With in depth research on the distributed platform,improving the performance and versatility of the distributed platform is to be the next task which should be considered.This paper is based on the background of distributed platform,analyzes the lack of the platform and the trouble it may exists when it is used to the automotive 4S shop collectors secondary identification applications.There are some flaws in the distributed platform.The coupler subsystem is not performing well when the load is high and the computational task lacks a common mode of operation.And the distributed platform lacks the interface program,which increase the difficulty when users develop their own application.In this paper,the communication model of the original coupler system has been changed.The communication model of thread pool is used to improve the performance of the coupler under heavy load,which can reduce the malfunction in the calculation process and accelerate the calculation speed.The function of coupler has been improved to increase the operational mode of the calculation task,and further enhance the versatility of the computing platform.A complete set of static library has been developed for the original distributed computing platform in order to simplify the development process.Finally,in order to meet the requirement of automotive 4S shop,an overall design has been constructed for the car 4S shop collectors secondary identification system which can do face recognition for the customers.This paper analyzes the research background and significance firstly,and then introduces the current situation of research at home and abroad.The second part discusses the advantages and disadvantages of the existing automobile 4S shop guests recognition system,and analyzes the application requirements of the current automobile 4S shop.The third part discusses the structure and the use flow of the distributed platform,analyzes the possible problems of the distributed calculation platform for the secondary identification process of the automobile 4S shop,and puts forward some improved method based on the analysis of the problem.The fourth part discusses the method to improve the distributed platform.The fifth part divides the system into modules,designs and achieves the function of each module.In the sixth part,the performance of the improved distributed platform and the guests recognition system is tested,and compared with the existing collector identification system in order to verify whether the performance of the platform has been improved.
