Abstract: The electromechanical system is a key project for the construction of highways. In the context of the development of the information age, the maintenance and management of highway electromechanical systems needs to keep pace with the times, and actively introduce the Internet of Things technology to provide solid data support for the intelligent management of mechanical and electrical equipment. Based on this, on the basis of a comprehensive understanding of the current status of highway electromechanical system maintenance management, this article expounds the application advantages of Internet of Things technology in highway electromechanical system maintenance management, and puts forward application countermeasures in order to realize the intelligence of highway electromechanical system maintenance management Chemical development.
