Analysis of the electro-mechanical system structure and function of the highway _ Analysis of Paper to write network: [Paper Keywords] highway structure and function of mechanical and electrical systems [Abstract] highway electrical systems play a major road traffic function auxiliary facilities management system, the highway is the main tool for the implementation of modern management. This paper analyzes the structure and function of mechanical and electrical systems, electromechanical systems and subsystems highway The structure and function of a more in-depth discussion. 1 Introduction Highway electrical systems play a major road traffic function auxiliary facilities management system, the highway is the main tool for the implementation of modern management. Expressway highway monitoring system consists of electrical charges, communications, lighting, power supply and safe operation of the tunnel security, and other subsystems. between the various subsystems within the system by the communications network and links. 2 highway monitoring system 2.1 highway monitoring system, is the use of modern means of line traffic flow, traffic conditions, environmental meteorology, facilities running to detect a series of intelligent control in accordance with the rules and strategies to generate control programs and control means to adjust the traffic flow state, thus achieving control traffic flow, improve the traffic environment and reduce traffic accidents, safe, comfortable, efficient transportation purposes. To achieve this purpose, the monitoring system must have three basic functions: (1) collect traffic flow data, to determine the traffic status: (2 depending on the traffic state, the implementation of control strategies to determine control parameters, (3) the implementation of control strategies, the effect on traffic flow control parameters. 2.2 According to the highway monitoring system functional requirements and characteris
