Credibility Assessment Of Integrated Platform Frame Of LED Display Based On The Internet Of Things

With the rapid development of the Internet and Internet of Things, technology of Internet of Things has made great progress in LED display applications. New requirements of keeping safety, reliability are quite a challenge. LED-DTIP (LED-Display Trust Integrate Platform, LED display credible integration platform) became one of the important developing direction of the LED display system. Our paper is focus on " The Credible Assessment of LED Display Integration Platform under Things of Internet",and utilizing the characteristics of the LED-DTIP system to study the system’s credibility assessment methods, this will have important value of academic and practical significance to promote the development of credible technology and LED display system.Our Paper gives an overview and system analysis on the LED-DTIP, summarizes the development of LED in various fields and the research advances of trusted technology home and aboard, and analysis the exist problem to be solved in LED-DTIP. Our major work include:①exploring the basic functional requirements and credibility needs of the LED-DTIP,building a LED-DTIP platform architecture, and explaining each building blocks, grading the level of credibility attribute of the LED-DTIP system according to the functional modules,and establishing the credibility indicators of the LED-DTIP system.②considering the system architecture level characteristics of LED-DTIP and the need of subjective factors in the assessment process, this paper proposed the method Analytic Hierarchy Process (AHP)Based on Fuzzy Synthetic Evaluation (FSE) to evaluate the system credibility, utilized AHP to establish the hierarchical model of system credibility, and use FSE to give a comprehensive evaluation to the overall credibility of system,and in order to eliminate subjective factors we introduced the triangular fuzzy judgment to calculate the weight of evaluation factors.③take The system development life cycle and the credibility of the assessment as theoretical support, deep analysis the LED-DTIP system development process, and to establish the credibility assessment process model of LED-DTIP system.④combined with the evaluation results of credible assessment, we make an analysis of the LED-DTIP system function modules, requirements analysis, functional structure, workflow and database design, and build the LED-DTIP system platform.This paper used FAHP evaluation method to convert the various parts of the credibility factor of the LED-DTIP system and the qualitative descriptions of the whole system into quantitative analysis, in order to further improve the system dependability. We can find out the key factor which affect the system credibility based on the evaluation results, this provide a feasible method to enhance the credibility of the system.
