The automatic management platform can ensure the stable operation of the Internet of Things(IoT)in smart city,but the function and performance of the platform can not meet the requirements of users.The research on the intelligent city IoT automatic management platform based on digital twin technology is proposed.According to the architecture of intelligent city IoT automation management platform,the information communication transmission server is designed,and the hardware design of the platform is completed.In the software design of the platform,based on the digital twin technology,the dynamic equation of the IoT in the smart city is constructed.Using the mapping relationship between the number of continuous packet losses of the IoT in the smart city and the maximum time delay value,the expected output of the IoT information in the smart city is set.Combined with the design of the IoT service information quality management algorithm in the smart city,the software design of the platform is completed,and the automatic management of the IoT in the smart city is realized.The test results show that the login function and operation function of the platform meet the requirements of users,reduce the packet loss rate of the platform,reduce the time lag effect,and ensure the stable operation of the IoT in smart city.
