Embodiment

[0031] This embodiment provides a method for analyzing the cause of service life of signaling equipment, including the following steps:

[0032] Step 1: Obtain historical status data of influencing factors. The historical state data includes the membership degree vectors of different states of the influencing factors at the current time point and the previous time point. Among them, the status of the influencing factors is divided into four categories: "excellent", "good", "medium" and "poor".

[0033] Step 2: Connect the membership degree values ​​of the same state at different times to determine whether there is an intersection. If there is no intersection point, it means that the influencing factor is not an effective cause of the deterioration of the signal equipment, so stop analyzing the factor and return to step 1. If there is an intersection, go to step 3.

[0034] Step 3: Determine whether there is a valid state transition point. Analyze the intersection points fr...

Abstract

The invention relates to a signal equipment service life cause analysis method. The method comprises the following steps of S1, obtaining historical state data of influence factors; S2, based on the historical state data, connecting the state values of the same state at different moments to obtain state curves of different states; S3, judging whether an intersection point exists in the state curve, if yes, executing the step S4, and if not, executing the step S1; and S4, judging whether the state curve has an effective state transition point, if yes, taking the influence factor as the cause ofthe service life of the signal equipment, and if not, executing the step S1. Compared with the prior art, the reason why the service life state of the signal equipment becomes poor can be scientifically analyzed, maintenance of the equipment is facilitated, and the service life of the equipment can be guided to be prolonged.

Description

technical field [0001] The invention relates to the field of safety analysis of facilities and equipment, in particular to a method for analyzing the cause of service life of signal equipment. Background technique [0002] The failures of urban rail transit mostly involve the signaling system. The use, maintenance and management of signaling system equipment (referred to as signaling equipment) are related to the smooth daily operation. Outdated signal equipment maintenance methods will make the reliability and safety not effectively guaranteed. [0003] The service life of the equipment refers to the period from when the equipment is put into use to when the equipment is out of use. The daily intensive operation puts a large load on the domestic urban rail transit signal equipment, which accelerates the aging process of the signal equipment. The maintenance of signal equipment is often based on the experience of technicians, and a scientific technical system has not yet ...
