Construction of Urban IOT Infrastructure Platform from the Perspective of Low Carbon Smart City Construction

Abstract

Under the promotion of technology and people's requirements, the construction of smart city in the new era has become a new trend of urban development. Intelligent means are used to improve the urban environment, enhance the safety factor of the city, meet the needs of urban traffic and other aspects, and realize the efficient, green and sustainable development of the city. This paper mainly introduces the research on the basic platform of urban Internet of things from the perspective of low-carbon smart city construction. Firstly, this paper discusses the role of the basic platform of the Internet of things to promote the low-carbon smart city, introduces the basic theory of the Internet of things, and builds the basic platform of the Internet of things based on the perspective of low-carbon smart city. This paper takes the intelligent gateway of the Internet of things as the communication core to realize the upload of data and the execution of control instructions. This paper proposes a method of automatic gateway configuration information, which can send configuration information from cloud to gateway. Gateway completes automatic configuration, reduces the workload of technical personnel. The terminal equipment connects to the cloud through mqtt protocol and carries out data communication. In this paper, the function and performance of the platform are tested. The experimental results show that the communication success rate of the Internet of things basic platform built in this paper reaches 100% when the communication distance is less than 150 meters, and 90% when the communication distance is 300 meters. The communication protocol used in this paper only takes 1ms to process a single message. In this paper, the street lamp control experiment is carried out, and the joint debugging test is carried out on the basic platform of the Internet of things. The results show that the control efficiency of the three control modes is the lowest of 98%. Through the implementation of this platform, we can reasonably monitor and manage urban energy use, improve the safety of energy use process, and promote the construction of low-carbon smart city.
