[0001]
BACKGROUND OF THE INVENTION
The present invention is to estimate the position of the water difference in the gas conduit network for estimating the position where the water including the stagnant water position and the water intrusion position are present when the water flows into the gas conduit from the wide area gas conduit network. The present invention relates to a method, a program for executing the estimation method, a recording medium on which the program is recorded, and a gas conduit network water difference estimation system using an information communication network.
[0002]
[Prior art]
The gas conduit has cracks and openings due to corrosion of the gas conduit, defective joints between the gas conduits, damage to the gas conduit due to sandblasting caused by rupture of water pipes buried in the vicinity of the gas conduit, etc. When it occurs, water flows into the gas conduit through these cracks and damaged parts such as openings, and a residual water is generated.
[0003]
If such water difference occurs, gas consumption equipment provided to gas consumers may cause problems such as difficulty in getting gas out of the burner, which may prevent stable gas supply. The person must accurately detect the position where the water difference has occurred as soon as possible and proceed to repair the damaged part of the gas conduit.
[0004]

[Means for Solving the Problems]
According to the first aspect of the present invention, based on the humidity of the gas, the humidity detection position, and the flow rate of the gas, a region affected by the difference water on the gas conduit network is estimated in advance, and the previously estimated difference water influence In the region, estimate at least one of the humidity after branching and the humidity after merging on the gas conduit network downstream of the humidity detection position in the gas supply direction, and based on the estimated value, This is a method for estimating the position of the water difference in the gas pipe network characterized by estimating the affected area.
[0006]
According to the present invention, the differential water influence region that is considered to be affected by the differential water on the gas conduit network in advance is estimated based on the humidity of the gas, the humidity detection position, and the gas flow rate. This is because it is considered that the humidity of the gas is similarly higher on the downstream side in the gas supply direction than the place where the humidity is high. In this way, even if the gas conduit branches off from the presumed difference water influence region, the humidity after the branch does not change compared to the humidity on the upstream side, and even if a plurality of gas conduits merge, Since the humidity after the merging is diluted approximately in proportion to the flow rate of each upstream gas conduit before the merging, the humidity level and flow rate at each humidity detection position, after merging, or branching Considering whether it is later or both, the differential water influence area can be estimated early and accurately from the humidity of the gas in each gas conduit.

According to the present invention, when estimating the position where water is present on the gas conduit network, the humidity of the gas increases in the gas supply direction depending on the humidity at each humidity detection position and the direction of gas flow.

This is because water is present on the upstream side of the humidity detection position, and water is not present on the upstream side of the position where the humidity is not detected. It is natural that there is humidity downstream from the humidity detection position, that there is no change in humidity after branching, and that the humidity after merging changes with the humidity and flow rate in each upstream conduit before merging. By considering it, the position where water exists can be determined early and accurately.

[0045]
Next, a procedure for executing the difference water position estimation program by the server computer C1 and estimating the difference water position will be described.
[0046]
FIG. 4 shows a part of the gas conduit network 30 for explaining a procedure for estimating the differential water influence area based on the spread of humidity using the gas conduit network differential water position estimation system 1 shown in FIG. FIG. 5 is a flow chart for explaining a procedure for estimating a gas conduit network difference water affected area of the gas conduit network 30 based on the spread of humidity, and FIG. 6 is a simulation selection on the conduit diagram simulation screen 11. FIG. 10 is a diagram showing a display screen when calculation is executed after selecting the “Estimate range of influence of humidity spread” field in box 12 and inputting humidity information.
[0047]
The gas conduit network 30 includes a plurality of gas conduits L1 to L8, and the two upstream gas conduits L1 and L4 are connected to the gas conduits L2 and L5 via nodes J1 and J3, respectively. The conduits L2 and L5 merge at the node J2, and continue from the downstream gas conduit L7 to the gas conduit L8 via the node J4. One of the upstream gas conduits L1 and L4 is branched and connected to the gas conduit L5 and the gas conduit L6 at a downstream node J3. Data of such a gas conduit network 30 is stored in the storage means 7 as a database.
[0048]
In step a1, as shown in FIG. 6, the simulation selection box 12 is clicked to select the “estimate the influence range of humidity” column, and the gas conduit display section 20 includes the region including the gas conduit network 30. The gas conduit network is displayed. In this state, the gas conduit L4 is selected by clicking with the mouse 16, and the reference node J3 on the downstream side in the gas flow direction is acquired from the selected reference gas conduit L4.
[0049]
In step a2, the next gas conduit L5 connected to the reference node J3 acquired in step a1 and the next node J2 opposite to the reference node J3 with respect to the gas conduit L5 are acquired.
[0050]
In step a3, it is checked whether there is any other gas conduit flowing into the next node J2 acquired in step a2, and if there is another gas inlet conduit, the next node J2 is stored in the temporary storage list.
[0051]
In step a4, the gas conduit L3 connected to the next node J7 is used as a reference gas conduit, and the above steps a2 to a3 are repeated until the next gas conduit cannot be obtained. In step a5, the gas is stored from the temporary save list. The node J2 is acquired, and in step a6, the flow rates of the other inflow gas conduits connected to the node J2 are summed.
[0052]
In step a7, the combined humidity value Hn at the node J2 is obtained. The combined humidity value Hn is such that the flow rate of one upstream gas conduit L2 is Q2m.^Three/ H, humidity is H2%, flow rate of other gas conduit L5 is Q5m^Three/ H, when the humidity H is 5%, the combined humidity value Hn is
Hn = {(Q2 × H2) + (Q5 × H5)} / (Q2 + Q5) (1)
So that the gas flow rate Q for each gas conduit before merging_{(1 ~ i)}And humidity H_{(1 ~ i)}And the product of each flow rate Q_{(1 ~ i)}Sum of ΣQ_{(1 ~ i)}It can be obtained as a value divided by. As an example, the humidity value Hn of the post-merging gas conduit L7 is Hn = {(16 × 0) + (4 × 40)} / (16 + 4) = 8% according to the above equation (1).
[0053]
In step a8, the gas conduit L7 connected to the acquired node J2 and the node J4 on the opposite side of the gas conduit are acquired.
[0054]
In step a9, the above steps a2 to a4 are repeated until the next gas conduit cannot be acquired with reference to the gas conduit L7 and the node J4 acquired in step a8. In step a10, the above steps a5 to a9 are temporarily stored. Repeat until there are no nodes in the list.
[0055]
In this way, on the gas conduit network 30 based on the humidity of the gas at the humidity detection position HP existing in the predetermined gas conduit network 30, the humidity detection position, and the flow rate of the gas for each of the gas conduits L1 to L8. Thus, the humidity of the gas in each gas conduit on the gas conduit network on the downstream side in the gas supply direction from the humidity detection position can be estimated.
[0056]
FIG. 7 is a system diagram showing a part of the gas conduit network 30 for explaining a procedure for estimating a certain position of water using the gas conduit network differential water position estimating system 1 shown in FIG. 8 is a flowchart for explaining a procedure for estimating the position of the gas conduit network 30 with water based on the direction of gas flow and the humidity H.
[0057]
In the present embodiment, it is determined that the humidity threshold H0 or higher is “with humidity”, and the upstream side of the gas conduit having a humidity lower than the threshold H0 is determined as “no humidity (no water)”, Naturally, it is determined that the downstream side of the gas conduit having a humidity equal to or higher than the threshold value H0 is humid, and the region of the change point from “without humidity” to “with humidity” is determined as “with water”. These determinations are made by the processing means 3 of the server computer C1 that executes the difference water position estimation program. That is, the server computer C1 executes the following steps b1 to b8 in this order.
[0058]
In step b1, the gas conduit L2 designated by clicking the mouse 16 on the screen is set as the reference gas conduit, and the node J2 downstream of the gas flow is acquired from the reference gas conduit L2 as the reference node.
[0059]
In step b2, it is checked whether the humidity H input by the input means 4 is equal to or higher than a threshold value H0 (10% in the present embodiment).
[0060]
In step b3, if the humidity H is larger than the threshold value H0, the gas conduit L7 connected to the reference node J2 and the node J4 on the opposite side with respect to the reference node J2 of the gas conduit L7 are obtained. A “with humidity flag” is set, and the acquired gas conduit L7 and node J4 are temporarily stored in the “with humidity storage list”. Further, the node J1 opposite to the reference node J2 is acquired, the “candidate flag with water” is set, and the acquired node J1 and the reference gas conduit L2 are temporarily stored in the “candidate storage list with water”. .
[0061]
In step b4, if the humidity H is smaller than the threshold value H0, the node J1 on the opposite side with respect to the reference node J2 is acquired, the “no water flag” is set, and the acquired node J1 and the reference gas conduit L2 are connected. Temporarily save to the “Waterless Save List”.
[0062]
In step b5, “with humidity” is confirmed. That is, in step b51, nodes and gas conduits are acquired from the “preserved list with humidity”, and in step b52, gas conduits and nodes connected to the downstream side of the acquired nodes are acquired. Next, in step b53, a “with humidity flag” is set for the acquired gas conduit and node and saved in the “with humidity list”. In step b54, the above steps b52 to b53 are repeated until no gas conduit can be acquired. In step b55, if there is a “humidity storage list”, the above steps b51 to b54 are repeated. When “with humidity” is determined in this way, the next step b6 is executed.
[0063]
In step b6, “candidate with water” is determined. That is, in step b61, nodes and gas conduits are acquired from the “candidate storage list with water”, and in step b62, gas conduits and nodes connected to the upstream side of the acquired nodes are acquired. Next, in step b63, a “candidate flag with water” is set to the acquired gas conduit and node, and the data is stored in the “candidate storage list with water”. In step b64, steps b62 to b63 are repeated until no gas conduit can be obtained. If there is a “candidate storage list with water” in step b65, steps b61 to b64 are repeated. When the “candidate with water” is thus determined, the next step b7 is executed.
[0064]
In step b7, “no water” is confirmed. That is, in step b71, nodes and gas conduits are acquired from the “waterless storage list”, and in step b72, gas conduits and nodes connected to the upstream side of the acquired nodes are acquired. Next, in step b73, a “waterless flag” is set for the acquired gas conduit and node and saved in the “waterless storage list”. In step b74, the above steps b72 to step until the gas conduit cannot be acquired. b73 is repeated, and if there is a “waterless list” in step b75, the above steps b71 to b74 are repeated. When “no water” is determined in this way, the next step b8 is executed.
[0065]

FIG. 11 is a system diagram showing a part of the gas conduit network 30 for explaining the procedure, and FIG. 11 is a flowchart for explaining a procedure for estimating the downstream side and the upstream side of the confluence of the gas conduit network 30.
[0068]
First, the forward calculation procedure from the junction shown in FIG. 9 to the downstream side will be described.
In step c1, a humidity detection position HP1 greater than or equal to the threshold value H0 is acquired on the selected gas conduit network 30.
[0069]
In step c2, the gas conduit L4 having each humidity detection position HP1 acquired in step c1 is used as a reference conduit, and a node J3 on the downstream side of the gas conduit is acquired as a reference node.
[0070]
In step c3, the next gas conduit L5 connected to the reference node J3 and the next node J2 opposite to the reference node of the next gas conduit are obtained.
[0071]
In step c4, it is checked whether or not there is another inflow gas conduit at the next node J2. If there is another inflow gas conduit, the next node is stored in the "temporary save list".
[0072]
In step c5, steps c2 to c4 are repeated using the gas conduit L3 connected to the next node J7 as a reference gas conduit.
[0073]
In step c6, the node J2 is acquired from the “temporary save list”.
In step c7, the flow rates of the other inflow gas conduits connected to the node J2 are summed.
[0074]
In step c8, the humidity value Hn resulting from the merge at the node J2 is calculated. If the calculated humidity value Hn is greater than or equal to the threshold value H0 in step 81, the “with water flag” is set to the gas conduit L7. If the humidity value Hn is less than or equal to the threshold value H0 in step c82, “ “Undetermined flag” is set in the gas conduit L7.
[0075]
In step c9, the gas conduit L7 connected to the acquired node J2 and the node J4 on the opposite side with respect to the reference node of the gas conduit are acquired.
[0076]
In step c10, the above steps c3 to c5 are repeated until the next gas conduit cannot be acquired with reference to the acquired gas conduit L7 and the node J4.
[0077]
In step c11, the above steps c6 to c10 are repeated until there are no nodes stored in the “temporary saving list”.
[0078]
In step c12, steps c1 to c11 are repeated for all humidity detection positions equal to or higher than the threshold value H0.

[0081]
In step c15, it is checked whether there is any other inflow gas conduit at the reference node.
[0082]
In step c16, if there is another inflow gas conduit, the merge reverse calculation is performed. Assuming that the other humidity value H5 on the upstream side is 0%, the humidity value H2 before merging is based on the flow rate Q2 of the gas conduit L2, the flow rate Q5 of the gas conduit L5, and the humidity value H7 of the gas conduit L7.
H2 = {(Q2 + Q5) / Q2} × H7
Can be calculated backwards. Similarly, the humidity value H5 before merging is
H5 = {(Q2 + Q5) / Q5} × H7
Can be calculated backwards. If the result of the merge determination is greater than or equal to the threshold value H0 in step c161, the “undecided flag” is set to the gas conduit. If the result of the merge determination is less than the threshold value H0 in step c162, “ Set the no water flag to the gas conduit.
[0083]
In step c17, the gas conduit L7 connected to the upstream side of the acquired node J4 and the node J2 opposite to the reference node of the gas conduit are acquired.
[0084]
In step c18, the above steps c15 to c17 are repeated until the next gas conduit cannot be acquired with reference to the acquired gas conduit L7 and the node J2.
[0085]
In step c19, the above steps c13 to c18 are repeated for all humidity detection positions below the threshold value H0.
[0086]

In step d1, the gas conduit L4 designated as “with water” is used as a reference gas conduit, and two nodes J3 and J6 on both sides are obtained from the reference gas conduit.
[0088]
In step d2, the elevations of the two nodes are acquired and compared. In step d3, if there is no altitude difference, the process ends. If there is an altitude difference, the process proceeds to the next. In step d4, the node J3 on the lower elevation side of the reference gas conduit L4 is acquired as the reference node.
[0089]
In step d5, the “area flag into which water flows” is set at the reference node J3, and is temporarily stored in the “area storage list into which water flows”. Further, the node J6 opposite to the reference node is obtained, and the “difference water intrusion position candidate flag” is set. The acquired nodes are temporarily stored in the “difference water intrusion position candidate storage list”.
[0090]
In step d6, the “area where water flows” is determined. In step d61, the node J3 is acquired from the “area saving list into which water flows”, and in step d62, the low-altitude gas conduit L5 and the node J2 connected to the acquired node J3 are acquired. In step d63, an “area flag into which water flows” is set in the acquired gas conduit and node, and is stored in an “area storage list into which water flows”.
[0091]
After repeating step d62 to step d63 in step d64 until no gas conduit can be acquired, in step d65, if there is a gas conduit or node stored in the “area saving list into which water flows”, step d61 is performed. Repeat ~ d64.
[0092]
In step d7, a difference water intrusion position candidate is determined. In step d71, the node J6 is acquired from the “candidate storage list of differential water intrusion position”, and in step d72, the high-altitude gas conduit L10 and the node J8 connected to the acquired node J6 are acquired. In step d73, a “difference water intrusion position candidate flag” is set for the acquired gas conduit and node, and is stored in the “difference water intrusion position candidate storage list”. In step d74, steps d72 to d73 are repeated until no gas conduit can be acquired. If there is a “difference water intrusion position candidate storage list” in step d75, steps d71 to d74 are repeated.
[0093]
In step d8, the above steps d1 to d7 are repeated by the number of gas conduits designated as “with water”, and there is a possibility that the water may spread in the gas conduit network 30 to a place lower than the position W4 where there is water. Since there is a possibility that water has flowed in from a place higher than the position W4 with water, a region having an altitude higher than the position W4 with water can be estimated as a candidate for the difference water intrusion position.

By comparing the water-free area obtained from the humidity, the humidity detection position, and the gas flow direction with respect to the differential water intrusion area in consideration of such a height difference, there is no water from the differential water intrusion area. The area excluding the area has the highest possibility as the position where the difference water has entered, and can be estimated as the difference water entry position.
