1 Subway electrical and mechanical equipment monitoring and control system technology needs analysis

Electrical and Mechanical Control System of the key equipment and lines, involved in disaster prevention and control of the controller and the joint line should be used redundant configuration, important equipment should be taken to the standby mode module level. Railway Electrical and Mechanical Control System most suitable for high reliability, strong anti-interference ability of the programmable logic controller as a controller, and the field bus is the subway system, electrical and mechanical equipment at the field level to monitor the best choice for the network. These methods contribute to the risk of decentralized systems to improve system reliability. In addition, mechanical and electrical equipment to monitor the railway system's hardware should be reliable, with good protection against dust, moisture, anti-jamming performance of industrial products. Electrical and Mechanical Control System equipment cabinet should be without prejudice to the premise of the cooling of the seal installation of high-quality, good dust-sealed, moisture-proof handle. Control cables should be considered anti-jamming measures such as shielding lines. 3.3 and the design of ventilation and air conditioning systems work closely with Railway Electrical and Mechanical Control System Design will be the soft should be professionals with the ventilation and air conditioning ventilation air-conditioning system in accordance with the railway of the characteristics of energy-saving programs agreed to jointly select the site of some important environmental control equipment (such as two-way valve), and give full play to the Electrical and Mechanical equipment monitoring system to enable the advantages of intelligent control ventilation and air conditioning systems to achieve the best energy-saving effect. 4 issues

In recent years, with a comprehensive automated subway system gradual maturity and perfection, as well as low-voltage distribution smart, intelligent lighting system functions, such as the increasingly powerful, it was discovered that they and Electrical and Mechanical Control System in the function of both hardware and software configuration duplication and cross - place. Therefore, in order to optimize

the allocation of resources to reduce the interface and improve overall system performance of these systems must be optimized. Electrical and Mechanical Control System and other systems should be merged, or through re-division of labor in order to better and integrated automation systems, intelligent low-voltage distribution system and intelligent lighting systems, which is the subway system to monitor electrical and mechanical equipment must address the problem.
