Embodiment 1

[0043] like figure 1 As shown, a dynamic evaluation method for utility tunnel operation and maintenance safety, including:

[0044] A method for dynamic evaluation of utility tunnel operation and maintenance safety, comprising:

[0045] S1. According to the risk events of the operation and maintenance safety of the pipeline corridor, sort out the safety elements of the man-machine-material legal circle of the operation and maintenance safety of the pipeline corridor, and determine the safety element data set;

[0046]S2. According to risk events, judge the risk evaluation level and risk occurrence probability of each safety element respectively, and quantify the risk evaluation level and risk occurrence probability; among them, the number of risk evaluation levels is not less than 5 levels, which can ensure Accuracy in risk assessment. In this embodiment, the number of levels is 6.

[0047] S3. Analyze the correlation and degree of influence among the security elements to o...

Embodiment 2

[0062] Different from Embodiment 1, S1 of this embodiment is also used to update security elements; in S5, abnormality analysis results are also displayed in the form of images. Specifically, the images are displayed in a color-coded manner. In this embodiment, green indicates safety, yellow indicates hidden dangers, and red indicates risks are occurring.

[0063] It is convenient for staff to understand the specific situation of abnormal analysis, and the way of color marking is simple and clear, and the overall situation is clear at a glance.

Embodiment 3

[0065] Different from Embodiment 1, in S5 of this embodiment, if the abnormality analysis result indicates that there is an abnormality, it is also graded according to the severity of the abnormality. If the level of abnormality is higher than the preset alarm level, an alarm will be issued. In this embodiment, the way of alarm is sound and light alarm.

[0066] In this way, in addition to knowing the specific situation of the abnormality, even inexperienced staff can clearly understand the specific severity of the abnormality. If the abnormal level exceeds the alarm level, it means that it needs to be dealt with in time, so an alarm is issued to remind the staff that there is an abnormality and deal with it in time. The way of sound and light alarm can attract the attention of the staff.

Abstract

The invention belongs to the technical field of pipe gallery monitoring operation and maintenance, and particularly relates to a pipe gallery operation and maintenance safety dynamic evaluation method, which comprises the steps of S1, determining a safety factor data set according to a risk event of pipe gallery operation and maintenance safety; s2, according to the risk event, respectively judging the risk evaluation level and the risk occurrence probability of each safety factor; s3, analyzing the relevance and the influence degree among the safety elements to obtain a logic incidence relation among the safety elements; analyzing the relevance and the influence degree among the risk events to obtain a logic incidence relation among the risk events; and obtaining an operation and maintenance analysis model according to the risk evaluation level and the risk occurrence probability of each security element in the risk event, the logic association relationship between the security elements and the logic association relationship between the risk events. According to the method, the influence factors of the pipe gallery can be comprehensively evaluated, and the operation and maintenance safety of the pipe gallery is dynamically evaluated and predicted in a targeted mode.

Description

technical field [0001] The invention belongs to the technical field of pipe gallery monitoring operation and maintenance, and in particular relates to a dynamic evaluation method for pipe gallery operation and maintenance safety. Background technique [0002] The pipe gallery (that is, the urban underground comprehensive pipe gallery) is a tunnel space built underground in the city. It is a structure and ancillary facilities that integrate electricity, communications, gas, heating, water supply and drainage, and various engineering pipelines. Through the pipe gallery, various engineering pipelines such as power, communication, gas, heating, water supply and drainage can be integrated and managed. [0003] The pipe gallery is a collection of various urban pipelines. Once an accident occurs, it may cause major economic losses and adverse social impacts. Therefore, in order to scientifically manage the operation of the utility tunnel, it is necessary to conduct a comprehensive...
