Research On Internet Of Things Technology For Smart Cinema Based On Future Network

The development of the Internet of Things(IoT)creates infinite possibilities for enhancing the film and television industry and promoting data integration,but due to the low level of intelligence in the domestic film and television industry infrastructure,the high cost of electronic tags for sensing devices,the lack of Internet addresses and the high cost of dedicated network lines,and the failure of server task scheduling strategies to consider the performance of different types of tasks on servers.This paper addresses these issues by designing a future networkbased IoT architecture with business oriented smart cinemas,with the following main work outcomes.(1)Focusing on the problem of server overload performance degradation due to excessive total user access traffic,an optimisation algorithm for dynamic load balancing is proposed from the perspective of load balancing of server clusters.The algorithm gives three weight updating schemes based on the relationship between the average time of server response to requests and the threshold value in the feedback period.During the weight update process,the current occupancy rate of each performance indicator of the server is combined to correct the degree of influence of the performance indicator on the server performance.The algorithm has a response time of no more than 10ms under a stress test of 2000 concurrent volumes,and can access up to 1429 concurrent requests at the same time.(2)Survey 400 citizens in three regions of Beijing,Suzhou and Shanghai on their vision of cinema development,analyse the current situation of cinema operation under the epidemic,propose a smart cinema architecture integrating data management and equipment management in response to current cinema development needs combined with IoT technology,and design and implement four core functional systems of smart cinema.(3)According to the characteristics of high collection frequency and large data volume in the process of data collection of cinema sensing equipment and the characteristics of high code stream and large capacity of data transmission between cinemas use Zigbee and future network networking communication respectively.Combined with digital domain names and DPC coding of cinema equipment for unified decimal coding,addressing and device management.(4)The development and testing of the smart cinema backend management system in the experimental network was completed.Experimental verification and performance analysis showed that the response time of the above system was less than 50ms during normal user operation,and the number of concurrent requests that the smart cinema system could handle was 2500 per second,with 90%of users taking no more than 2s.The feasibility and development potential of the system in the future network was effectively verified.
