The pipeline evaluating of described pipeline fuzzy risk analysis typing that module receives comprises accident possibility occurrence and damage sequence severity two parts, the evaluating of described accident possibility occurrence comprises third party's destruction, corrosion failure, design defect, misuse failure, and the evaluating of described damage sequence severity comprises combustion gas and ambient conditions, physical damage, non-physical loss.

The set evaluation algorithms of described pipeline fuzzy risk analysis module is based on fuzzy mathematical model, and is provided with the submodule that calculates pipeline evaluating index weight, and this submodule is passed to evaluation algorithms with the parameter weight that calculates.

Described pipeline fuzzy risk analysis module also is provided with auxiliary administration module and equipment, comprises the database that is used to preserve the risk assessment object information and storer etc.

The instrument of the described detection of the utility model information, record, detection can be routine measurement instrument, scanner, monitoring camera-shooting device etc., the segmented conduit peripheral information of gathering is gathered the computing machine of typing end by typing interface and data line input information, the computing machine of information acquisition typing end is exported to the business administration end by LAN (Local Area Network) or internet with data, the module of business administration end is carried out risk assessment according to tube circumference information to gas ductwork, and each module characteristic is as follows:

1, duct segments administration module

Realize piping unit sectional management function by the duct segments administration module, provide as basic data management operations such as interpolation, modification, deletions.

Interpolation comprises to be added evaluation unit and adds waypoint, and adding evaluation unit is the pipeline in a highway section of interpolation, and as the Tianhe North Road, Guangzhou City, highway section titles such as Zhong Shan main road are to add the sub-pipeline section that certain bar highway section is divided down and add waypoint.Sub-pipeline section is the evaluation object of risk assessment, is " day northern 2# valve from east to west 442 " as the waypoint in Milky Way North Road.

2, pipeline section peripheral information administration module

The fuzzy risk analysis that with the pipeline section is carrier need be collected a series of pipeline section surrounding enviroment data message, to information add, the database manipulation of deletion, modification etc.The present invention by pipeline section peripheral information administration module provide pipeline section surrounding enviroment information typing, deletion, revise, browse and quick positioning function.Comprise that pipeline essential information, third party destroy data, corrosion failure data, design factor data, maloperation factor data, consequence severity data, the look facility of pipeline evaluating information and risk assessment object information also is provided simultaneously.The typing of information can be passed through external input device, manually or automatically imports by the hardware accessory.

3, fuzzy risk analysis module

Fuzzy risk analysis will be imported evaluating earlier, the evaluating inputting interface that provides by pipeline fuzzy risk analysis module.The user can pass through external input device, manually or automatically imports.The pipeline fuzzy risk analysis respectively from the accident possibility and damage sequence severity two aspects estimate, the accident possibility occurrence comprises the content of 4 aspects: third party's destruction, corrosion failure, design defect, misuse failure.When pipeline is not estimated as yet, evaluating is empty, needs the user to carry out the selection input of parameter according to the environmental aspect of tube circumference, and the pipeline fuzzy risk analysis need be determined the object estimated, be evaluation unit and the waypoint of determining in the duct segments management, thereby determine the pipeline section of needs assessment.

Accident possibility occurrence as one of system ambiguous risk assessment parameter of the utility model comprises 4 aspects: third party's damage parameter, corrosion failure parameter, design defect parameter and misuse failure parameter.

Third party's damage parameter input item is to bury the ground degree of depth, pipeline ten contents of accordance of situation, pipeline subsurface picture, resident's situation, construction activities, line walking management, vehicle activity, geological condition, squatter building situation and planning on the ground.According to national standard " Code for design of city gas engineering " regulation (GB50028-2006), different geological conditions buries the scope difference of the ground degree of depth.Therefore bury the parameter of the ground degree of depth and select to be divided into 3 kinds of situations: driveway, walkway, paddy field.

Corrosion failure evaluating: consider the actual difficulty that city buried steel gas pipeline excavation detects, the native system evaluation module has been set up respectively based under the non-excavation situation of pipeline and based on the appraisement system parameter under the pipe excavation situation, thereby can carry out the fuzzy risk analysis of two kinds of situations to pipeline.Based on the evaluating under the non-excavation situation of pipeline be: 6 of pipeline external anti-corrosion layer, soil corrosivity, pipeline section wall thickness, cathodic protection, current interference and active times; Based on the evaluating under the pipe excavation situation be: 5 of soil, anticorrosive coat outward appearance (marking), joint, pipeline and active times.

The design defect evaluating comprises: the integrality of steel pipe safety coefficient, system's hydraulic testing, design data, designing unit's qualification and 5 contents of designing unit's experience.The misuse failure evaluating comprises: working specification formulation and implementation status, operator training, construction maloperation, 4 contents of workmen's quality.

Two damage sequence severity parameter input as the utility model system evaluation module evaluating comprises 3 aspects, that is: combustion gas and ambient conditions, physical damage, non-physical loss.

And combustion gas and ambient conditions include: 5 of the possibilities of medium toxic hazard, repairing control, natural situation, pipeline surround ground situation, second accident.

Physical damage then comprises: the damage of accident point population situation, buildings, the economy of repairing drop into 3.

Non-physical loss then comprises: to corporate reputation and influence of society, to the influence of environment, to the public's influence 3.

After all parameter inputs finish, determine evaluation object again, just can begin to carry out the fuzzy risk analysis of pipeline section.And evaluation result preserves database automatically, so that the user extracts the information of checking this segment pipe in the future.

4, Risk-warning module

The utility model is that the risk size of pipeline is carried out early warning by pipeline Risk-warning module.Pipeline need just can carry out Risk-warning through behind the fuzzy risk analysis.Pipeline Risk-warning module is selected corresponding grade early warning according to the alert degree of wanting early warning, finds the pipeline of the various early warning of response.Select " tertiary risk early warning (yellow early warning) " as the user, then pipeline Risk-warning module will be listed the pipeline section that meets the tertiary risk early warning by its user interface that provides, and accident possibility occurrence evaluation of indexes grade, and provide early warning measure and suggestion.

5, described business administration end also is provided with auxiliary administration module.
