The Study On Risk Control Of Chengdu Metro Line1Mechanical And Electrical System

Our country city orbit traffic has now entered the stage of full development of centralized construction, city rail transportation in the national economy and people life status is becoming more and more important, it is affecting and changing people’s mode of thinking and life trajectory. People can enjoy the security of rail service, Metro electrical system security can be guaranteed to be one of the key factors.In Chengdu Metro Line1project of mechanical and electrical system safety risk control as the starting point, constructed by vehicle, signal, power supply, screen door, comprehensive monitoring, automatic fare collection, tunnel ventilation, track and other9subsystems, the main electrical and mechanical system project risk control system, the purpose is from the overall planning and exploration of mechanical and electrical system the project in the project each phase of operation safety may exist in the risk assessment and response, realization of metro operation safety equipment, mainly includes the following aspects:The article around Chengdu Metro Line1electrical system project risk control is effective to this problem, by using the FMEA method to identify the main risk of the fault tree is set up, and the fault tree analysis, assessment of risk control results, to meet the level of risk control and reduce the requirements. In order to solve the risk control measures are effective, really reduce the risk of project of the key issues, good risk is best managed by a ring.Built for Chengdu Metro electrical system characteristics of the risk assessment matrix, definition from R1to R4four risk levels for risk identification, provided a basis, put forward throughout the metro system project design, manufacture, installation, commissioning, operation and maintenance of the whole process of safety risk control concept, but also the main innovation of the paper.To identify the main risk countermeasures are put forward, namely:the train doors under unsafe circumstances open; trains on the line of fire; train in positive impact in operation; train derailment; passengers stranded in orbit and shielding door. Mechanical and electrical system for subway project safety provides reference.
