Embodiment

[0033] The embodiment of the present invention takes a fire accident of a fan electrical control cabinet in a subway station as an example to explain the risk management and control method of urban rail transit system based on layered and hierarchical cycle control.

[0034] The electrical control cabinet of the station's main exhaust fan in the environmental control electronic control room caught fire and smoke, and the smoke spread to the ancillary rooms and public areas of the station hall, causing 7 trains to pass, the subway station to be closed, and the transfer passage to be closed.

[0035] Accident handling process:

[0036] The FAS host computer in the comprehensive control room alarms, and the station comprehensive controller and station master on duty confirm through the FAS graphics workstation that the alarm room is the environmental control electronic control room in the auxiliary room area on the east side of the station hall floor.

[0037] The on-duty station...

Abstract

The invention provides an urban rail transit system risk management and control method based on hierarchical circulation control, and belongs to the technical field of urban rail transit operation control. The method comprises the following steps: determining system risk nodes and association relationships among the risk nodes based on historical operation accident data of urban rail transit, andconstructing an accident association network; then constructing a risk control objective function of the accident association network; finally, calculating the entropy of the risk control objective function according to a hierarchical cyclic control theory; and managing and controlling the system risk by using a risk control strategy corresponding to the minimum entropy value. According to the invention, by considering that different risk nodes have different attribute information, a risk management and control strategy is provided. The accuracy of risk control is improved. A risk link is cutoff before an accident happens. The probability of risk happening is reduced. A decision is made from the overall perspective. The interaction relation between all levels of the system can be effectively coordinated, an optimal control result is obtained, and system safety is achieved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit operation control, in particular to a risk management and control method for urban rail transit systems based on layered and hierarchical cycle control. Background technique [0002] The safe operation of urban rail transit is a complex state formed by the interaction of various facilities and equipment. In various urban rail transit facilities and equipment, the smallest structure that can be controlled by people is called a risk node, and there are a large number of risk nodes in the complex system of urban rail transit. Different risk nodes have different attribute information, and each attribute information is related to each other. Therefore, in a large number of risk nodes, the change of a certain factor will have an unpredictable impact on the system, and the result of human control of a single factor will deviate from the control target due to complex interactions. [0003] Ur...
