After years of development, the target enterprise has already had a large number of CM put into use. With the development of information technology and the continuous progress of science, CM continues to move towards the direction of information and intelligence, and the pace of integration of information technology and CM is gradually accelerating. In order to ensure the safety of the company's equipment assets, improve the project construction quality, and provide data support for purchasing and upgrading equipment, it is imperative to conduct more detailed processing and analysis of the data generated during the construction process. The main purpose of this paper is to study the deficiencies and coping strategies in the management of CM and equipment. This paper analyzes the functional and non-functional requirements in detail according to the research background, determines the goal of the platform, and divides the design of the platform into three parts: the Internet of Things access platform, the Internet of Things management platform, and the database. Then, the CM service management platform is divided into three parts: data access module, security management module and function module, and their implementation processes are described respectively. Finally, the usability and stability of the platform are verified by functional testing and stress testing.
