As an example, it may be provided to the safety rating system 400 through a non-transitory computer readable medium in which general pipe information or pipe state information is stored.

Here, the non-transitory readable medium refers to a medium that stores data semi-permanently, rather than a medium that stores data for a short moment, such as a register, a cache, a memory, and the like, and can be read by a device. Specifically, the above-described various applications or programs may be provided by being stored in a non-transitory readable medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.

The safety rating system 400 includes an information processing module 410 , a data export module 420 , a risk index management module 430 , a risk calculation module 440 , a cycle manager 450 , and a facility location information management module 460 . , may include a safety level indicator (470). Each component in the safety rating system 400 may operate through the arithmetic operation of the processor 150 of FIG. 2 .

The information processing module 410 may input/manage various types of information required for risk calculation. The information processing module 410 may include a linkage/input module 411 , a linkage collection module 413 , and an information input manager 415 .

The linkage/input module 411 may manage non-periodic information, and collect irregular piping information (ie, fixed information) or irregular supply pipe information stored in the external system 10 .

The linkage collection module 413 is a module for managing real-time information, and may collect pressure information from devices such as a static pressure device and a test box in real time.

4 is a view for explaining a supply pipe unit according to an embodiment of the present disclosure.

Various facilities (551, 522, 553) (eg, static pressure, valve, valve box) are directly connected to the pipe by welding, and corrosion or poor welding of these facilities has a high impact on the safety of the pipe. do.

In this regard, in the present disclosure, risk assessment is performed in units of supply pipes, without measuring the degree of risk in units of pipes. Hereinafter, an operation of performing risk assessment in units of supply pipes according to the present disclosure will be described.

Referring to FIG. 4 , the first pipe 550 is equipped with two facilities 551 and 552 , and has a total of 4 welding sites including both ends for connection with other pipes. A space between these four welding parts is referred to as a supply pipe, and the first pipe 550 of FIG. 4 may be divided into three supply pipes (supply pipe 1, supply pipe 2, and supply pipe 3).

Specifically, the first supply pipe is a section between the end of the first pipe and the first facility 511 , the second supply pipe is a section between the first facility 511 and the second facility 522 , and the third supply pipe is It is a section between the second facility and the other end of the first pipe.

As such, the present disclosure calculates the degree of risk in units of the above-described supply pipe, and may consider a pipe connection part to which a type of facility such as a static pressure device, a valve, an insulating joint, etc. is attached. On the other hand, when a plurality of facilities are arranged adjacent to each other (for example, when the static pressure and the valve are arranged within 1 m), the intermediate point between the static pressure and the valve is not divided into a separate supply pipe section between the static pressure and the valve. A supply pipe can be set as a single pipe connection.

It is because one pipe emphasizes the connection part, but the danger of the pipe is different based on the connection part. In order to consider this point, in the present disclosure, such a connection unit area is defined as a 'supply pipe', and the risk of piping is evaluated in a supply pipe unit. A specific method of calculating the risk index and safety grade in each supply pipe will be described later with reference to FIG. 5 .

On the other hand, a general gas management system generally monitors more than 100,000 pipes. Since such a large number of pipes are managed, when more detailed information is provided to a user or an administrator as it is, it may be difficult to check the information.

Accordingly, in the present disclosure, it is possible to provide information to a user or an administrator by calculating the level of risk in units of supply pipes and calculating the level of risk in units of blocks based on the calculated information. Here, the block divides the region into a plurality of regions, and each of the divided regions may be a block. In addition, in implementation, a block group (or region) including several blocks may be placed above the block, and it is also possible to calculate the degree of risk for the block group.

For example, as shown in FIG. 4 , the first block 510 includes a first pipe, and risk information of the supply pipe 1, the supply pipe 2, the supply pipe 3, and the supply pipe 7 may be used.

And the second block 520 includes a portion of the first pipe 550, the second pipe 560, and the fifth pipe, and the risk of the second block 520 is the supply pipe 2, the supply pipe 3, the supply pipe 4, and the supply pipe. It can be calculated from the risk information of 5.

And the third block 530 includes a third pipe 570, a fourth pipe 580, and a fifth pipe, and the risk level of the third block 530 is the risk information of the supply pipe 5, the supply pipe 6, and the supply pipe 7. can be calculated.

5 is a diagram illustrating an example of pipe information and supply and information according to an embodiment of the present disclosure.

Referring to FIG. 5 , the unit, importance, and cycle of each risk factor and the corresponding risk factor are disclosed. Here, the importance is the importance of the factor, and 1 point may be given to a normal factor and 2 points to a risk factor. And the period indicates whether the corresponding information is always used, information that is changed in real time is used, or is arbitrarily used.

A score for each factor shown is given for each pipe and each of the supply pipes, and the values of the above-described factors are added to calculate a risk index for the corresponding supply pipe. The risk grade (or risk score) assigned to each factor ranges from 0 to 4, and the higher the score, the higher the risk. The given score cannot be exemplified, and the score range may be variously changed.

Hereinafter, how to assign a risk class to each risk factor will be described.

The pipe information may include installation year information, coating material information, and pipe diameter information, and may include information on a supply pipe included in each pipe. Such information may have information for judging the following grades (for example, the year of installation is a direct number such as 1997), and grade information (grade 1) or direct scores (0 points, 1 point) according to the information , 2 points).

The installation year information has information on the year in which the pipe was installed. Usually, the 15-year target is for the pipeline tightness test, and the 20-year target is the target for precise safety diagnosis. If the installation year is around 10 years, 0 points can be given, 11-15 years 1 point, 16-20 years 2 points, 21-30 years 3 points, and 31 years or more, 4 points.

Coating material information is the presence or absence of a protective layer. Pipes before 1996 have a primary and secondary protective layer in a circular extrusion method, but the adhesion between the outer part of the pipe and the corrosion protection layer is weak, so there is a possibility of corrosion. Considering this point, 1 point can be given to piping before 1997, and 0 points can be given to piping after 1997 when the T-die extrusion method was applied.

The pipe diameter information is information about the size of the pipe, and the pipe diameter can be used as it is, and since the pipe diameter and the pipe size are proportional, the pipe thickness can be used as a standard. For example, if 300A or more, the pipe thickness is 7mm or more, 0 points, 300A~150A, 1 point, 150~100A, 2 points, 100A~65A, 3 points, 65A or less, if the pipe thickness is less than 4mm, 4 points can do.

The supply pipe information includes information on the presence or absence of a guard plate, information on the presence or absence of a double pipe, information on the branch protection iron plate, information on the depth of burial, information on the presence or absence of an exhaust device, information on the river flow section or the number of under-potential cases, information on the static pressure device attached to the supply pipe, information on the static pressure device attached to the supply pipe It may include valve information, insulating joint information, test box information or receiver information, and the like.

The guard plate presence information is information indicating whether a guard plate is attached to the supply pipe, and a guard plate is installed to prevent damage due to excavation work when the medium pressure pipe is buried. For example, if the guard plate is mounted, 0 points may be given, and if the guard plate is not mounted, 2 points may be given.

The double pipe presence or absence information indicates that a double pipe is installed in a case where the depth is insufficient or the separation distance from other obstacles is not secured. This is information indicating whether such a double pipe is installed. there is.

Branch protection plate information is information indicating when the branch protection plate was installed. Since September 2013, the protection plate has been installed in the low-pressure branch pipe. For example, if the pipe is installed after September 2013, 0 Points are awarded, and 2 points may be awarded if previously installed.

As the burial depth information, direct depth information may be used as depth information at which the corresponding pipe is buried, and burial width information may be used. For example, if the burial depth is 1.2m or more, 0 points will be awarded, 1 point between 1.2m and 1m, 2 points between 0.9m and 0.7m, 3 points between 0.6m and 0.4m, and 4 points between 0.3m and below. can

The presence or absence of a drainer is information indicating whether a drainer is attached, and corrosion may occur in the pipeline if there is a lot of leakage current in the subway. Considering this point, 2 points can be given if the drainer is installed, and 0 points if the drainer is not installed.

The river descent section information is information indicating whether the buried area is a river section, and may be given 2 points if it is a river descent section, or 0 points otherwise.

The deep coating damage rate of damage is information indicating the coating damage rate of the pipe. If the coating damage rate (%IR) is less than 5, 0 points, 0 to 5%, 1 point, 5 to 15%, 2 points, 15 If it is between ~30%, 3 points can be given, and if it is 30 or more, 4 points can be given.

The information on the number of cases below the potential is information indicating the number of cases where the potential was not reached. Therefore, 0 points may be given if the number of unsatisfied cases is 0, 1 point if the number of missed cases is 1 or 2, 2 points if 3 or 4 cases, 3 points if 5 or 6 cases, and 4 points if 7 or more cases.

The information on the static pressure device attached to the supply pipe is information indicating whether the static pressure device is attached to the supply pipe. Most of the body of the static pressure device is made of metal, and the strength of the static pressure device only decreases regardless of the operating time. Therefore, if it is attached, 1 point may be given and if it is not, 0 points may be given.

On the other hand, when a static pressure device is attached, information on the installation year of the static pressure device, pressure information of the static pressure device, operation information, and the like may be additionally used as risk factors.

The valve information attached to the supply pipe is information indicating whether the valve is attached to the supply pipe, and corrosion may occur in the corresponding part according to the valve attachment. In this regard, 1 point can be given if the valve is attached, and 0 point if it is not attached.

On the other hand, when a valve is attached, information on the valve type (specifically, there are various leakage factors according to the valve type, which may be taken into account) and information on the operating state may be used as additional risk factors.

The insulation joint information is information indicating whether an insulation joint is attached to the supply pipe. Specifically, the insulating joint is a non-conductive joint of a buried pipe, and is a structure installed in the pipe for anti-corrosion potential management. Therefore, having an insulating joint in the pipe means that the possibility of gas leakage increases. If it is attached, 1 point, if not attached, 0 point can be given.

The test box information may be assigned a value corresponding to a potential value provided in real time from the test box. For example, if it is less than -1400mv, 0 points, if it is -1400mv to -1200mv, 1 point, if it is -1200mv to -1000mv, 2 points, if it is -1000mv to -850mv, 3 points, and if it is -850mv or more, 4 points can be given.

The receiver information is information indicating whether or not the receiver is attached to the supply pipe. If it is attached, 1 point may be given, and if it is not attached, 0 points may be given.

The operation information may have excavation information, safety work information, and inspection information, and such information may be included as piping information, which is common to all piping.

On the other hand, the risk factors shown in FIG. 5 are not exemplified, and some of the factors illustrated in the implementation may be omitted, and other factors may be additionally used in addition to the above-described factors. In addition, risk scores (or risk classes) for factors may also be scored in other ways, unless their values are illustrative.

9 is a flowchart for explaining a gas pipe risk measurement method according to an embodiment of the present disclosure.

Referring to FIG. 9 , first, pipe information for a gas pipe and supply pipe information for each of a plurality of supply pipes constituting the pipe are stored.

And based on the pipe information and the supply pipe information, the risk is determined in units of the supply pipe, which is a part of the pipe. Specifically, for each supply pipe unit, the risk index may be calculated in consideration of various evaluation factors (the presence or absence of a protective plate, the presence or absence of a double pipe, etc.) and the importance of the evaluation factors.

And it is possible to determine whether there is a risk based on the calculated risk ratio. For example, if the risk index is 80 or more, it is judged that there is a serious risk, if 75 or more and less than 80, it is a dangerous state, 65 or more but less than 75 is a state of caution, 50 or more and less than 65 is a state of interest, 50 Below, it can be judged as a normal state.

The determined level of risk may be displayed on the display. Specifically, the degree of risk for each pipe may be displayed. Alternatively, it is possible to display only information about the supply pipe in a certain state (interest, caution, danger, serious) in the pipe.

As described above, the gas pipe risk measurement method according to the present embodiment calculates the risk in units of a supply pipe in consideration of a welding site with a high risk of occurrence, so that a more accurate and precise stability evaluation is possible.
