Description

  The present invention presents on the screen the relationship between the water breakage of the water distribution pipe in the water distribution pipe and the opening and closing of the gate valve, thereby making it possible to efficiently perform maintenance, inspection, repair, etc. of the water supply facility. The present invention relates to a distribution pipe analysis system having a valve display function.

Conventionally, as a system that inputs construction points on the electronic map on the screen and extracts the range of water distribution pipes that should be shut off and the customer information affected by water shutoff to construct the construction points, For example, the construction target pipeline is indicated with the mouse, the water pressure, flow rate, flow direction, etc. of the pipe near the construction target pipeline is calculated by pipe network calculation. A system has been proposed that searches and highlights, displays a list of attribute information of water-stopping consumers, and further determines and displays the order of valves to be closed from information such as the flow direction (for example, Patent Document 1). )
Japanese Patent No. 3047993

  The system proposed in the above-mentioned Patent Document 1 simply displays all the gate valves in the water shut-off range as “a gate valve to be closed in the water shut-off range”, and all the gate valves in the water shut-off range. There is no facility to present to the user which of these need to be plugged in and which do not really need to be plugged. That is, the system of Patent Document 1 is characterized in that a water shut-off range is searched and a valve closing priority and a closing order are determined from the flow direction of each pipe in the water shut-off range. It is not intended at all to separately present a gate valve that needs to be closed and a gate valve that does not need to be closed on the screen.

  However, in an actual water distribution pipe, there are many stoppers (portions where water does not flow any further), and therefore the water shutoff range is shut off among the plurality of gate valves included in the water shutoff range. Therefore, there are gate valves that do not need to be closed. It is a waste of work to close a gate valve that does not need to be closed in order to cut off a certain water cutoff range. Therefore, conventionally, a user who is a water utility needs to close the cap based on his own experience while looking at the distribution pipe diagram of the water cutoff range where all the gate valves in the water cutoff range are uniformly displayed. On the spot, I found a gate valve that was not found visually from the water distribution pipe diagram, and handwritten the letters and marks of "no plugging required" on paper water distribution pipe diagrams. However, if the decision as to whether or not each gate valve needs to be closed in this way is left to an on-site worker, the work efficiency at the site will be reduced.

  The present invention is for solving such problems of the prior art, and when a predetermined construction location or construction water distribution pipe is input, it is plugged in order to shut off the water shutoff range necessary for the construction. Distinguish required shutoff gate valves and shutoff gate valves that do not need to be closed and present them to the user side, and display all the water distribution pipes included in the water shutoff range as water shutoff pipes on the screen so that the user can understand them. In addition, it is possible to display a list of information on customers included in the water shutoff range on the screen, and it has a stop valve display function that makes it possible to improve the efficiency of waterworks construction at the site. The purpose is to provide a distribution pipe analysis system.

The distribution pipe line analysis system having a stop valve display function according to the present invention for solving the above-described problems has a plurality of ends that are separated by contact points, gate valves, or stopper parts with other water pipes, respectively. In order to control the flow of water in the water distribution pipe, a gate valve connected to the end of all or some of the water distribution pipes, and water flows further through one end of the water distribution pipe A distribution pipeline database that records a distribution pipeline including a stopper for preventing it from being associated with a map, and associates a distribution pipeline in a predetermined area with a map based on data from the distribution pipeline database A distribution pipe display means for displaying and a construction distribution pipe including the construction place in the distribution pipe on the screen where the distribution pipe display of the predetermined area is displayed by the distribution pipe display means Water distribution pipe input means to input , A gate valve connected to the construction water pipe directly or via another water pipe based on the input from the construction water pipe input means, and implements water cutoff for construction of the construction water pipe Based on the output from the closing gate valve search means and the closing gate valve search means for searching for the closing gate valve to be closed, the distribution pipe display means displays the distribution pipe in a predetermined area. A plug for presenting the plug gate valve searched by the plug gate valve search means on the screen as a plug gate valve to be plugged in order to shut off the water for construction of the construction distribution pipe. A gate valve presenting means, and the water distribution line database is related to each water pipe to which the gate valve is connected with respect to each gate valve. the partition is not Whether the (Sakitomeben) ", which is recorded as attribute information of each gate valve, said stoppered gate valve retrieval means, both ends of the specified construction water pipe by the treated region like specifying means For each of the water distribution pipes that are ahead of each other, with respect to a plurality of gate valves connected directly to the construction water pipe or via other water pipes, from the gate valve located closest to the construction water pipe Each gate valve is in relation to the construction water pipe or a water pipe close to the construction water pipe until the gate valve or stopper portion to be plugged in each water pipe is sequentially searched for the gate valves located at distant positions. Refer to the water distribution pipeline database to determine whether it is a stop valve as described above, and is a gate valve that is not a stop valve, and connects the construction pipe distribution pipe and the “pipe network through which water flows bidirectionally”. For each of the routes most The gate valve on the tube side, is to find a plugging gate valve should be stoppered to implement the suspension of water supply for construction of the working water pipe, it is characterized in.

  In addition, the distribution pipe analysis system having a stop valve display function according to the present invention includes a plurality of distribution pipes whose both ends are separated by contact points with other distribution pipes, gate valves, or stopper parts, In order to control the flow of water in the pipe, a gate valve connected to the end of all or some of the water pipes, and to prevent water from flowing further through one end of the water pipe A distribution pipeline database that records a distribution pipeline including a stopper in association with a map, and a distribution pipeline for displaying the distribution pipeline in a predetermined area in association with a map based on data from the distribution pipeline database Construction for inputting a construction location in the distribution pipeline or a construction pipeline including the construction location on the screen on which the distribution pipeline in a predetermined area is displayed by the pipeline display means and the distribution pipeline display means Distribution pipe input means and the construction distribution pipe input Based on the input from the means, for each of the water distribution pipes ahead of each end of the construction water distribution pipe designated by the construction means etc. designating means, directly with the construction water distribution pipe or through other water distribution pipes For a plurality of connected gate valves, there is a gate valve or plug stopper to be closed for each water pipe line sequentially from the gate valve located closest to the construction water pipe to the gate valve located further away. Until a search is made, each gate valve says, “When the construction water pipe is shut off, whether the other water pipe connected to the construction water pipe and the gate valve closes the gate valve. Regardless of whether or not it is a stop valve that automatically enters a water cutoff state, it is a gate valve that is not such a stop valve, Each of the routes connecting the `` flowing pipe network '' A shut-off gate search means for searching the gate valve closest to the construction water distribution pipe as a shut-off gate valve to be closed in order to shut off the water for construction of the construction water pipe; Based on the output from the search means, on the screen of the distribution pipe displayed by the distribution pipe display means, only the closing gate valve searched by the closing gate search means is used for the construction of the construction water pipe. And a closing gate presenting means for presenting to the user as a closing gate valve to be closed in order to perform water shutoff.

  Further, in the water distribution pipe analysis system having a stop valve display function according to the present invention, starting from the construction water distribution pipe, the water distribution pipe located closest to the distribution water pipe is gradually changed to the water distribution pipe located further away. Regardless of whether or not there is a stop valve in the middle, each water pipe until the tip of the water pipe reaches the closing gate or stopper is extracted as a water stop pipe included in the water shutoff range. Based on the output from the water cutoff pipe extracting means and the output from the water cutoff pipe extracting means, the water cutoff pipe is presented to the user on the screen of the water pipe displayed by the water pipe display means. It is desirable to provide a water cutoff pipe display means.

  Moreover, in the water distribution line analysis system having a stop valve display function according to the present invention, the water distribution line database includes information on consumers connected to the water distribution pipes through the water supply pipes. The water-disruption customer extraction means for extracting the consumers connected to the water-break water distribution pipe extracted by the water-break water distribution pipe extraction means, and Based on the output, on the screen of the water distribution pipe displayed by the water distribution pipe display means, information on consumers connected to the water distribution pipe to be cut off for construction of the construction water distribution pipe to the user It is desirable to provide a water-shutdown consumer presenting means for presenting.

  Furthermore, in the water distribution line analysis system having the stop valve display function according to the present invention, the water distribution line display means connects the gate valves in the water distribution pipes of the predetermined region with “the vertices of two triangles connected to each other”. In addition, the gate valve that does not have the attribute of the stop valve in the gate valve is “a mark in which the inside of the two triangles is white or filled” The gate valve having the attribute of the stop valve in the gate valve is “the gate valve of the gate valve in relation to the water pipe connected to one end of the gate valve. If it has an attribute, the inside of the triangle on the side adjacent to the water distribution pipe is white or filled, and the relationship with the water distribution pipe connected to the other end of the gate valve The gate valve has the attribute of a stop valve If there is for displaying the mark "the internal side of the triangle adjacent its water pipe is in the filling or white background is a reverse manner to the case of the, it is desirable.

  According to the present invention, when a predetermined construction location or construction distribution pipe is inputted, a shut-off gate valve that needs to be closed and a shut-off valve that does not need to be shut off in order to shut off the water shut-off range necessary for the construction. As shown in the past, “The user who is a water utility has a distribution pipe diagram of the water shut-off area in which all the gate valves in the water shut-off area are uniformly displayed. `` Based on your own experience, you can visually find a gate valve that does not need to be capped from the water distribution diagram, and hand-write letters and marks that do not need to be clogged into the paper water distribution diagram etc. '' It becomes unnecessary, greatly reducing the burden on site workers and making the work for water shutoff much more efficient. That is, the present invention relates to a shut-off gate valve that needs to be closed and a shut-off valve that does not need to be closed in order to shut off the water shut-off range necessary for the construction when a predetermined construction location or construction water pipe is input. It is possible to automatically distinguish it from the (stop valve) and present it to the user (water service provider) side. We had to judge by hand which ones need to be closed and which ones need not be plugged in. '' To do.

  Further, in the present invention, in particular, the system side starts from the construction water distribution pipe and starts from the water distribution pipe closest to it to the water distribution pipe located further away, and whether or not the stop valve is in the middle. Regardless, since each water pipe is extracted as a water shutoff pipe included in the water shutoff range until the end of the water pipe reaches the stopper gate valve or stopper, the system side is closed on the way. Even when a stop valve that does not need to be recognized is recognized, the previous water distribution pipe can be recognized as a water cutoff water distribution pipe.

  In addition, according to the present invention, since all the water distribution pipes included in the water cutoff range can be displayed on the screen so that the user can see them as the water cutoff pipes, the user should be able to close which gate valve in the water cutoff range. Thus, it is possible to easily recognize which gate valve does not need to be closed.

  In addition, according to the present invention, it is possible to display a list of information of all customers included in the water cutoff range on the screen, and from this point, it is possible to improve the efficiency of waterworks on site.

  Furthermore, in the present invention, the water distribution pipe display means displays the gate valve in the water distribution pipe in a predetermined area by “a mark formed by connecting the vertices of two triangles to each other”, A gate valve that does not have the attribute of the stop valve in the gate valve is indicated by “a mark in which the insides of the two triangles are both white or filled”, and A gate valve having an attribute is: "If the gate valve has the attribute of a stop valve in relation to a water pipe connected to one end of the gate valve, it is adjacent to the water pipe. The interior of the triangle on the side is white or filled, and the gate valve does not have a stop valve attribute in relation to the water pipe connected to the other end of the gate valve If inside the triangle on the side adjacent to that water pipe The operator displays the mark "that is the filling or white background is a reverse manner to the case of the. Therefore, according to the present invention, whether a user (water supply company) or an operator who performs system development input work has an attribute of a stop valve for each gate valve in the water distribution pipeline, and Therefore, it is possible to easily grasp which water pipe has the attribute of the stop valve as having the attribute of the stop valve by simply looking at the screen. In particular, when the operator who performs the input work of system development is performing the work of associating the gate valve with the water distribution pipe, whether the gate valve that he / she currently inputs is input as a stop valve or normal Since it can be easily grasped on the screen whether the input has been made as a gate valve, it is possible to minimize input mistakes related to the attribute of the gate valve.

  The best mode for carrying out the present invention is the mode shown in Example 1 described below.

  FIG. 1 is a schematic block diagram showing Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 denotes a plurality of water distribution pipes whose both ends are each separated by a contact with another water pipe, a gate valve, or a stopper, and all or to control the flow of water in the water distribution pipe Associating a distribution pipe with a map that includes a gate valve connected to the end of some distribution pipes and a stopper for preventing water from flowing further through one end of the distribution pipe. It is a water distribution pipeline database recorded.

  In FIG. 1, reference numeral 2 denotes a display area input unit composed of a keyboard, a mouse, and the like. A user (water supply company) desires display by specifying a keyword such as a city name / district name or a map on the screen. A display area input unit 3 for inputting the area of the water distribution pipe 3 is based on the area inputted from the display area input unit 2 and distributes the water distribution pipe corresponding to the area and a map related thereto to the water distribution pipe database. An area search unit 4 for searching and retrieving from 1 is a display control unit for displaying on the display 5 a water distribution pipeline and a map of the searched area based on data from the area search unit 3. .

  In FIG. 1, reference numeral 6 denotes a pointing device such as a mouse, and the user inputs a construction (planned) location on the water distribution pipe and map screen of the searched area displayed on the display 5. The construction point input unit 7 for closing the plug to shut off the water distribution pipe (construction water distribution pipe) including the construction point from the distribution pipe line database based on the construction point input from the construction point input unit 6 A shut-off gate search unit for searching for a shut-off valve that needs to be operated, 8 is a distribution pipe included in a water shut-off range when the shut-off gate valve is closed based on an output from the shut-off gate valve search unit 7 The water drainage pipe extraction unit 9 for searching for information is extracted based on the output from the water drainage pipe extraction unit 8 such as the name, address, and telephone number of the consumer connected to the water drainage pipe. Water outage consumer extraction unit, and is a.

  In the first embodiment, output data from the closing gate search unit 7, the water cutoff distribution pipe extraction unit 8, and the water cutoff consumer extraction unit 9 are also sent to the display control unit 4, and the display 5 Is displayed.

  That is, in the first embodiment, on the display 5 screen, on the distribution pipe and map in the area specified by the user, a plug gate valve that needs to be plugged to shut off the water distribution pipe including the construction site, And the water cutoff pipe which is shut off by the closure of this stopper gate valve is displayed superimposed on the water pipe and map of the predetermined area. Moreover, in the present Example 1, the display frame which shows all the consumers connected to the said water cutoff water pipe (the consumer who is influenced by water cutoff) on the water distribution pipe line and map of the said predetermined area of a display 5 screen. However, they are superimposed and displayed in a manner that is emphasized so as to be different from the display frames of other consumers, such as colored, shaded, and hatched lines. Further, in the first embodiment, on the display 5 screen, the water distribution pipe and map in the area specified by the user, the plug gate valve that needs to be closed in order to shut off the water distribution pipe including the construction location, and this A list of all consumers connected to the water shutoff pipe is displayed in a small window on the screen on a part of the screen on which the water shutoff pipe that is shut off by closing the shutoff gate valve is displayed.

  Next, an example of the operation of the first embodiment will be described with reference to FIGS. 2a and 2b. In FIG. 2a, 11, 12, 13, and 14 are gate valves, 15 is a stopper (a part that prevents water from flowing further), 16 is a contact point of a water distribution pipe, and 17 is a gate valve 11 A water distribution pipe with the contact 16 as an end, 18 is a water distribution pipe with the contact 16 and the gate valve 12 as ends, 19 is a water distribution pipe with the contact 16 and the gate valve 13 as ends, and 20 is a gate 13. And 14 are water distribution pipes, and 21 is a water distribution pipe having the gate valve 14 and the stopper 15 as ends. Among the gate valves 11-14, a water pipe 22 on the left side of the gate valve 11 and a water pipe 23 on the right side of the gate valve 12 are respectively a part of a pipe network through which water flows bidirectionally. It has become.

In the first embodiment, each of the gate valves 11-14 is recorded in the water distribution pipeline database 1 as attribute information as to whether it is a stop valve in relation to each water distribution pipe to which it is connected. Keep it. Specifically, the gate valves 11 and 12 are recorded as normal gate valves that are not in a stopped state on the downstream side when viewed from the water pipes 17 and 18. The gate valve 13 is recorded as a stop valve because it is in a water stop state on the downstream side as viewed from the water distribution pipe 19. That is, the white triangular mark indicated by reference numeral 13 a in FIG. 2 a indicates that the gate valve 13 is in a stopped state on the downstream side when viewed from the water distribution pipe 19. Further, a black triangular mark indicated by reference numeral 13b in FIG. 2a indicates that the gate valve 13 is not in a stopped state on the upstream side as viewed from the water distribution pipe 20.

That is, in the first embodiment, in FIG. 2a, the gate valves 11 and 12 that are not in the stopped state are displayed by marks in which the insides of the two triangles are both white. In addition, since the gate valve 13 is stopped at the tip (downstream side) when viewed from the water pipe 19, the inside of the triangle 13 a on the side adjacent to the water pipe 19 is white, And since it is not a stop state in the tip (upstream side) seeing from the water pipe 20 connected to the other end part of the gate valve 13, the inside of the triangle 13b on the side adjacent to the water pipe 20 Is displayed with a mark that is a solid (black background) that is the reverse of the above case (note that the above is a partition having the attributes of other stop valves other than the gate valve 13) The same applies to valves).

Similarly, the gate valve 14 is in a stopped state at the tip (downstream side) when viewed from the distribution pipe 20, and is not at the tip (upstream side) when viewed from the distribution pipe 21. Show.

Now, assuming that the user inputs a location indicated by reference numeral 22a in FIG. 2a as a construction location by the construction location input unit 6 in FIG . 1, the closing gate search unit 7 in FIG. 1 has a layout including the construction location 22a. Search for a closing gate valve that needs to be closed to shut off the water pipe 19.
The stopper gate search unit 7 firstly has a water distribution pipe located above the construction water distribution pipe 19 (a water distribution pipe located at the end (downstream side) of the end of the construction water distribution pipe 19 on the gate 13 side). The gate valve to be closed is searched as follows.
First, the closing gate valve search unit 7 recognizes the gate valve 13 connected to the upper end of the water pipe 19 in the drawing, and determines whether or not it is a stop valve and its attribute information. Reference from database 1. When recognizing that the gate valve 13 is a stop valve in relation to the water distribution pipe 19, the attribute information of the gate valve 14 further downstream of the water distribution pipe 20 downstream of the gate valve 13 is obtained from the water distribution pipe. Reference is made from the road database 1. When it is recognized that the gate valve 14 is a stop valve in relation to the water distribution pipe 20, the stopper 15 located further downstream of the water distribution pipe 21 on the downstream side of the gate valve 14 is recognized. Since the water does not flow beyond the stopper 15, the stopper gate search unit 7 determines that there is no gate valve to be plugged above the water pipe 19, and the water pipe 19 is shown. The search for the gate valve to be closed for the upper water distribution pipe ends here.

Next, the plug-in gate search unit 7 selects the gate valve to be plugged for the water-distribution pipe (the water-distribution pipe on the upstream side of the contact 16 of the construction pipe 19) below the construction pipe 19. Perform the search as follows:
  First, the stopper gate search unit 7 recognizes the gate valve 11 located at the tip of the water pipe 17 at the lower left of the water pipe 19 (upstream of the water pipe 17 when viewed from the water pipe 19). Referring to the attribute information of the gate valve 11 from the water distribution pipeline database 1, the gate valve 11 is a normal gate valve in relation to the water distribution pipe 17 (and therefore in relation to the water distribution pipe 19), that is, a stop valve. Recognizing that it is not a valve, it is determined that it is a gate valve to be closed.
  Further, the closing gate search unit 7 recognizes the gate valve 12 located at the tip of the water pipe 18 at the lower right of the water pipe 19 (upstream of the water pipe 18 as viewed from the water pipe 19). Then, referring to the attribute information of the gate valve 12 from the water distribution pipeline database 1, the gate valve 12 is a normal gate valve in relation to the water distribution pipe 18 (and therefore in relation to the water distribution pipe 19). Recognizing that it is not a stop valve, it is determined that it is a gate valve to be closed.
  Here, the search for the gate valve to be plugged for the water distribution pipe line below the water distribution pipe 19 is terminated.

  Based on the output from the closing gate search unit 7, the display control unit 4 causes the gates 11 and 12 to shut off the water distribution pipe 19 including the construction site 22a as shown in FIG. 2a. It is displayed on the screen as a gate valve to be closed, and the other side valves 13 and 14 are shown on the screen to the user that they are non-stop valves that do not need to be closed (on the distribution pipe on the display 5 screen) By not displaying “closure” while displaying the gate valves 13, 14, or by displaying the word “non-closed” in the vicinity of the gate valves 13, 14, the user side I understand that it is a stop valve).

  Further, the drainage water pipe extraction unit 8 in FIG. 1 is based on the output from the closure gate search unit 7 and all the water pipes included in the water cutoff range when the gate valves 11 and 12 to be closed are closed. To extract. In the example of FIG. 2a, the water cutoff water pipe extraction unit 8 starts from the construction water distribution pipe 19 including the construction distribution place 22a, and the water distribution pipe line (the end of the construction water distribution pipe 19 on the contact 16 side) below the drawing. The water distribution pipes 17 and 18 in the water distribution pipes ahead of each other are recognized as shut-off water distribution pipes, the gate valves 11 and 12 to be plugged are recognized, and the search ahead is finished. Moreover, the said water cutoff water pipe extraction part 8 starts from the construction water distribution pipe 19 containing the said construction distribution location 22a, and the water distribution pipe line (the tip of the construction water distribution pipe 19 of the end of the construction water distribution pipe 19 by the side of the gate valve 13 side). Recognizing the water distribution pipe 20 ahead of the stop valve 13 existing in the existing water distribution pipe), and further recognizing the water distribution pipe 21 ahead of the stop valve 14 ahead of it When the unit 15 is recognized, the search is terminated.

  In this way, the water cutoff water pipe extracting unit 8 is eventually provided with the water pipes 17, 18, 19, 20 and the sandwiched between the two gate valves 11 and 12 to be plugged and the stopper 15. 21 is extracted as a water cutoff pipe included in the water cutoff range. The extracted water cutoff pipes 17, 18, 19, 20, and 21 are displayed as a water cutoff range on the water distribution pipe on the display 5 screen by the display control unit 4 (in the example of FIG. 2a, the water cutoff range). In the present invention, the water cutoff pipe is highlighted in various ways, for example, by displaying it with a solid line of a color different from that of a normal water pipe. You may do it).

  Moreover, the water cutoff consumer extraction part 9 of FIG. 1 is based on the output from the said water cutoff distribution pipe extraction part 8 to the said water cutoff distribution pipes 17, 18, 19, 20, and 21 via a water supply pipe and a water meter. Information (name, address, telephone number, etc.) of connected consumers (see A, B, C, D, E, and F in FIG. 2a) is stored in the distribution pipe database 1 (each distribution pipe and its distribution pipe). And the customer information connected to the network are recorded with reference to each other. And based on this extraction result, all the consumers A- connected to the said water cutoff water pipe 17, 18, 19, 20, and 21 on the water pipe and the map of the said predetermined area of a display 5 screen. The display frame indicating F is superimposed and displayed in a manner that is emphasized so as to be different from the display frames of other consumers by, for example, diagonal lines. Further, the extraction result of the consumer is sent to the display control unit 4, and is displayed by the display control unit 4 in the form of a list (see FIG. 2b) in a small window in the display 5 screen.

Next, another example of the operation of the first embodiment will be described with reference to FIGS. 3a and 3b. In FIG. 3a, parts common to FIG. 2a are given the same reference numerals and description thereof is omitted. Now, assume that the user inputs the part indicated by reference numeral 22b in FIG. 3a as the construction part by the construction part input unit 6 in FIG. In this case, the closing gate valve search unit 7 of FIG. 1 searches for a closing valve that needs to be closed in order to shut off the water distribution pipe 20 including the construction site 22b as follows.
First, the plug shut-off valve search unit 7 performs the distribution for the water distribution pipe line below the construction water distribution pipe 20 (the water distribution pipe on the downstream side of the construction water pipe 20 on the gate valve 13 side). The gate valve 13 below the water pipe 20 is recognized, and the attribute information of the gate valve 13 is referred to from the water distribution pipeline database 1.
Then, the shut-off gate valve search unit 7 recognizes that the gate valve 13 is an ordinary gate valve (not a stop valve) in relation to the water pipe 20 , determines that it is a gate valve to be closed, and the water pipe The search for the gate valve to be closed for the 20 water distribution pipes at the bottom of the figure ends here.

Moreover, the plugging gate valve searching unit 7, the illustrated upper water distribution pipeline of the working water pipe 20 (water distribution pipeline located on the downstream side of the working water pipe 20) shown above (downstream of the water pipe 20 The gate valve 14 on the side) is recognized, and the attribute information of the gate valve 14 is referred to from the water distribution pipeline database 1. Then, when the plug gate valve search unit 7 recognizes that the gate valve 14 is a stop valve in relation to the water distribution pipe 20, it further searches for a gate valve downstream of the gate valve 14. . Then, the plugging gate valve searching unit 7 recognizes the Sentome portion 15 further downstream of the previous water pipe 21 located downstream of the previous ahead valve in which gate valve 14. Since the stopper 15 does not circulate water earlier, the stopper gate search unit 7 ends the search for the gate valve to be closed for the upper distribution pipe of the water pipe 20 in the figure. .

  As described above, the pluggage gate search unit 7 eventually searches only the gate valve 13 as a gate valve that needs to be closed in order to shut off the water distribution pipe 20 including the construction site 22b. The display control unit 4 receives the output from the pluggage gate search unit 7 and displays the gate valve 13 as a gate valve to be closed on the display 5 screen, and the other gate valve 14 needs to be closed. Present to the user as a non-stop valve.

  Further, the water cutoff distribution pipe extraction unit 8 starts from the distribution pipe 20 including the construction location 22b based on the output from the closing gate valve search unit 7, and continues to the lower distribution pipe line (the construction distribution line). The water cutoff pipe located in the end of the end of the water pipe 20 on the side of the gate valve 13 is searched for, but the gate valve 13 to be plugged is connected to the lower side of the water pipe 20. Therefore, here, the search for the water cutoff pipe for the water pipe below the water pipe 20 in the figure is finished. Further, the water cutoff distribution pipe extraction unit 8 starts from the distribution pipe 20 including the construction site 22b based on the output from the closing gate valve search unit 7 and then continues to the upper distribution pipe (the construction distribution line). A water cutoff pipe located in the end of the end of the water pipe 20 on the side of the gate valve 14 is searched for and the gate valve 14 above the water pipe 20 is recognized. Since it is a stop valve, it recognizes the water pipe 21 ahead. Next, the water cutoff water pipe extraction unit 8 recognizes the stopper 15 which is further ahead of the water pipe 21, but the stopper 15 does not allow water to flow further, so here Then, the search for the water cutoff pipe for the water pipe on the upper side of the water pipe 20 is finished.

  In this way, the water cutoff pipe extraction unit 8 eventually shuts off the water distribution pipes 20 and 21 sandwiched between the gate valve 13 and the stopper part 15 to be plugged. Extracted as water pipes included in the range. The display control unit 4 highlights the extracted distribution pipes 20 and 21 on the display 5 screen as a distribution pipe scheduled to be shut down with a broken line or the like based on the output from the water cutoff distribution pipe extraction unit 8 (FIG. 3a, 20, 21).

  Further, the water cutoff consumer extraction unit 9 extracts the customer information connected to the water cutoff pipes 20 and 21 with reference to the water distribution pipeline database 1 based on the output from the water cutoff pipe extraction unit 8. Then, the extracted consumer information is transmitted to the display control unit 4. Based on the transmitted consumer information, the display control unit 4 displays all the consumers connected to the water cutoff pipes 20 and 21 on the water pipes and maps in the predetermined area on the display 5 screen. The display frame indicating A-D is superimposed and displayed in a manner in which the display frame is emphasized so as to be different from the display frames of other consumers (E, F, etc.) by, for example, diagonal lines. The extracted consumer information is displayed in the form of a list (see FIG. 3b) by the display control unit 4 on the display 5 screen.

Next, still another example of the operation of the first embodiment will be described with reference to FIGS. 4A and 4B. In FIG. 4a, parts common to FIG. 2a are denoted by the same reference numerals and description thereof is omitted. Now, assume that the user inputs the part indicated by reference numeral 22c in FIG. 4a as the construction part by the construction part input unit 6 in FIG. In this case, first, the closing gate search unit 7 in FIG. 1 searches for a closing valve that needs to be closed in order to shut off the water distribution pipe 21 including the construction site 22c as follows.
The capping gate search unit 7 firstly displays the water distribution pipe below the water distribution pipe 21 (the water distribution pipe located upstream of the construction water distribution pipe 21) below the water distribution pipe 21 (upstream side). ) And the attribute information of the gate valve 14 is referred to from the water distribution pipeline database 1. The closing gate search unit 7 recognizes that the partition valve 14 is an ordinary gate valve (not a stop valve) in relation to the water pipe 21 and determines that the gate valve is to be closed. The search for the gate valve to be plugged for the water distribution pipe 21 below is terminated here.

Moreover, the plugging gate valve searching unit 7 recognizes the about illustration of water pipes 21 upward (downstream of the working water pipe 21), Sentome portion 15 in the illustrated upper (downstream side) of the water pipe 21 . Since the stopper 15 does not allow water to flow downstream from the stopper 15, the stopper gate search unit 7 does not have a gate valve to be closed in the upper distribution pipe of the distribution pipe 21. This is the end of the search for the gate valve to be closed for the water distribution pipe above the water distribution pipe 21 in the figure.

  As described above, the pluggage gate search unit 7 eventually searches only the gate valve 14 as a gate valve that needs to be closed in order to shut off the water distribution pipe 21 including the construction site 22c. The display control unit 4 receives the output from the closing gate valve search unit 7 and displays only the gate valve 14 as a gate valve to be closed on the display 5 screen.

End the search with. Further, the water cutoff water pipe extraction unit 8 starts from the water distribution pipe 21 including the construction site 22c based on the output from the plug shut-off gate valve search unit 7 (the plugging of the construction water pipe 21 is stopped). The water cutoff pipe is searched for the tip of the end on the side of the section 15, but the search is terminated here because the stopper 15 is located above the water pipe 21.

  In this way, the water cutoff distribution pipe extraction unit 8 eventually shuts off the water distribution pipe 21 only in the water distribution pipe 21 sandwiched between the gate valve 14 and the stopper 15 to be plugged. It is extracted as a water distribution pipe contained in The display control unit 4 highlights the extracted distribution pipe 21 on the display 5 screen with a broken line or the like as a distribution pipe scheduled to be shut off on the display 5 screen based on the output from the water cutoff distribution pipe extraction unit 8 (FIG. 4a). 21).

Based on the transmitted consumer information, the display control unit 4 displays the consumers A and B connected to the water cutoff pipe 21 on the water pipe and map in the predetermined area on the display 5 screen. The display frame to be displayed is superimposed and displayed in a manner that is emphasized so as to be different from the display frame of another consumer (C-F or the like) by, for example, diagonal lines. The extracted consumer information is displayed in the form of a list (see FIG. 4b) on the display 5 screen by the display control unit 4.

Next, the operation when the first embodiment is applied for the analysis of the water distribution pipe of FIG. 5a described above will be described. Now, assume that the user inputs a construction location indicated by reference numeral 72a in FIG. 5a by the construction location input unit 6 in FIG. Then, the closing gate search unit 7 in FIG. 1 searches for a closing valve to be closed in order to shut off the water distribution pipe 52 including the construction location 72a.
The plug shut-off valve search unit 7 first partitions the water distribution pipe 52 below the water distribution pipe 52 (the water distribution pipe existing upstream from the end of the construction water distribution pipe 52 on the contact 40 side). The valves 31 and 32 are recognized, and the attribute information of the gate valves 31 and 32 is referred from the water distribution pipeline database 1. Then, because they have an attribute of normal gate valve in relation to the distribution pipes 50 and 51 the partition valve 31 and 32, the plugging gate valve searching unit 7, plugging the gate valve 31 Recognize that it should be a gate valve.

Next, the closing gate search unit 7 is configured to distribute the upper distribution pipe 52 (the distribution pipe existing downstream from the end of the construction distribution pipe 52 on the gate 33 side). The gate valve 33 is recognized, and the attribute information of the gate valve 33 is referred to from the water distribution pipeline database 1. Then, since this gate valve 33 has the attribute of a stop valve in relation to the water distribution pipe 52, the closing valve search valve 7 recognizes that the gate valve 33 is a stop valve , and closes the plug. Judge that there is no need to do .
Therefore, next, the closing gate valve search unit 7 recognizes the gate valves 34, 35, 36 further downstream of the gate valve 33, and obtains attribute information of these gate valves 34, 35, 36. Reference is made from the distribution pipeline database 1. Then, these gate valves 34, 35, 36 all have the attribute of a stop valve in relation to the respective water distribution pipes 56, 58, 60 on the water distribution pipe 53 side (upstream side). Therefore, the closing gate valve search unit 7 recognizes that the gate valves 34, 35 , and 36 are stop valves , and determines that it is not necessary to close the valves.
Therefore, next, the closing gate valve search unit 7 recognizes the gate valves 37, 38, 39 further downstream of the gate valves 34, 35, 36, and these gate valves 37, 38, The 39 attribute information is referred from the water distribution pipeline database 1. Then, these gate valves 37, 38, 39 all have the attribute of a stop valve in relation to the water distribution pipes 64, 66, 68 on the water distribution pipe 53 side (upstream side). Therefore, the closing gate valve search unit 7 recognizes that each of the gate valves 37, 38, 39 is a stop valve , and determines that it is not necessary to close the gate .
Next, the closing gate valve search unit 7 tries to find a gate valve further downstream of the gate valves 37, 38, 39, but before the gate valves 37, 38, 39. Since each of the water distribution pipes 65, 67, 69, 70, 71 is a “one kind of stopper” by each of the water distribution pipes, the search is terminated here.

  From the above search, the closing gate search unit 7 outputs only the gate valves 31 and 32 as gate valves to be closed. The display control unit 4 receives this output and displays only the gate valves 31 and 32 as gate valves to be closed on the screen of the water distribution pipe as shown in FIG. 39 is presented to the user as a stop valve that does not need to be closed (for example, “non-closed” is displayed near the gate valve 33-39).

  Further, based on the output from the closing gate search unit 7, the water cutoff water pipe extraction unit 8 in FIG. 1 starts from the water distribution pipe 52 including the construction location 72a as a starting point, and the water distribution pipe lines (upward and lower in the figure) Recognize and search for water distribution pipes that are in the water cutoff range for each of the water distribution pipes 52 at the ends of the construction water distribution pipe 52 sequentially from the side closer to the water distribution pipe 52 to the far side (in that case, For the first stop valve, the search for the water pipes ahead is continued, and the search is terminated when the gate valve or the first stop valve to be closed is reached. And the said water cutoff distribution pipe extraction part 8 is, after all, each distribution pipe 65,67,69,70,71 which forms the said gate valve 31,32 and the said "a kind of stopper part" which should be plugged. It is necessary for water distribution pipes 50-71, which are a combination of the water distribution pipes sandwiched between the water distribution pipes and the respective water distribution pipes forming the "one type of stoppers", to shut off the water distribution pipe 52 including the construction site 72a. Search for water pipes included in the water outage range. The display control unit 4 receives the output from the water drainage pipe extraction unit 8 and highlights the water distribution pipes 50-71 as a water shutoff pipe with a broken line or the like on the screen of the water pipe as shown in FIG. 5a.

  Moreover, the water-disruption consumer extraction part 9 of FIG. 1 is a consumer (a consumer who is affected by a water stop) connected to the water stop water distribution pipe 50-71 based on the output from the water stop water distribution pipe extraction part 8 respectively. Is extracted from the water distribution pipeline database 1 and transmitted to the display control unit 4. Based on the transmitted consumer information, the display control unit 4 displays all the consumers connected to the water cutoff pipe 50-71 on the water distribution pipe and map in the predetermined area on the display 5 screen. The display frame indicating AQ is displayed in a superimposed manner, for example, in a manner in which the display frame is emphasized so as to be different from the display frames of other consumers by hatching. In addition, the display control unit 4 displays the extracted list of consumers (see FIG. 5b) based on the output from the water cutoff consumer extraction unit 9 in the screen of the distribution pipe as shown in FIG. 5a.

Next, still another operation of the first embodiment will be described with reference to FIGS. 6a and 6b. Now, assume that the user inputs a construction location indicated by reference numeral 72b in FIG. 6a by the construction location input unit 6 in FIG. Then, the closing gate search unit 7 in FIG. 1 searches for a closing valve to be closed in order to shut off the water distribution pipe 54 including the construction location 72b as follows.
The plug shut-off valve search unit 7 is configured to distribute water pipes for water pipes below the construction water distribution pipe 54 (distribution pipes existing upstream from the end of the construction water pipe 54 on the contact 41 side). The gate valve 33 connected to the lower end of the water distribution pipe 53 connected to the terminal 54 through the contact point 41 is recognized, and the attribute information of the gate valve 33 is referred to from the water distribution pipe line database 1. Then, since this gate valve 33 has an attribute of a normal gate valve in relation to the water distribution pipe 53, the plug gate valve search unit 7 recognizes that the gate valve 33 is a gate valve to be closed. The search for the gate valve to be closed for the water distribution pipe below the water distribution pipe 54 ends here.

Next, the shut-off gate search unit 7 has a water distribution pipe on the right side of the water distribution pipe 54 (each water distribution pipe on the downstream side of the end of the construction water distribution pipe 54 on the contact 42 side). For each of these, the gate valves 34, 35, 36 are recognized, and the attribute information of these gate valves 34, 35, 36 is referred from the water distribution pipeline database 1. Then, these gate valves 34, 35, and 36 all have the attribute of a stop valve in relation to each of the water pipes 56, 58, and 60 on the water pipe 54 side (upstream side). Therefore, the closing gate search unit 7 recognizes that each of the gate valves 34, 35, and 36 is a stop valve and determines that it is not necessary to close the gate .
Therefore, next, the closing gate valve search unit 7 recognizes the gate valves 37, 38, 39 further downstream of the gate valves 34, 35, 36, and these gate valves 37, 38, The 39 attribute information is referred from the water distribution pipeline database 1. Then, these gate valves 37, 38, 39 all have the attribute of a stop valve in relation to the water pipes 64, 66, 68 on the water pipe 54 side (upstream side). Therefore, the closing gate valve search unit 7 recognizes that each of the gate valves 37, 38, 39 is a stop valve and determines that it is not necessary to close the gate .
Therefore, next, the closing gate valve search unit 7 tries to find a gate valve further ahead ( downstream side ) of the gate valves 37, 38, 39. There is only each water distribution pipe 65, 67, 69, 70, 71 on the downstream side of this, and each of these water distribution pipes 65, 67, 69, 70, 71 forms a kind of stopper. Therefore, the search for the gate valve to be closed for the water distribution pipe on the right side of the water distribution pipe 54 in the drawing is completed.

  From the above search, the closing gate search unit 7 outputs only the gate valve 33 as a gate valve to be closed. Upon receiving this output, the display control unit 4 displays only the gate valve 33 as a gate valve to be closed on the screen of the water distribution pipe as shown in FIG. Present to the user as a stop valve that does not need to be closed.

  Further, the water cutoff distribution pipe extraction unit 8 of FIG. 1 starts from the construction distribution pipe 54 including the construction location 72b based on the output from the closing gate valve search unit 7, and the both ends of the construction distribution pipe 54 are started. For each of the existing distribution pipes, the distribution pipes that enter the water shut-off range are sequentially recognized and searched from the distribution pipe close to the construction distribution pipe 54 to the distant distribution pipe. The search for the previous water pipe is continued, and the search is terminated when the gate valve or the stop valve to be closed is reached). As a result, the water cutoff water pipe extraction unit 8 is sandwiched between the gate valve 33 to be plugged and the water pipes 65, 67, 69, 70, 71 forming the “type plug stopper”. The water distribution pipe 53-71, which is a combination of the water distribution pipes and the water distribution pipes forming the “one type of stoppers”, is brought into a water cut-off range necessary to cut off the water distribution pipe 54 including the construction location 72b. Search for included water pipes. The display control unit 4 receives the output from the water cutoff pipe extraction unit 8 and highlights the water pipe 53-71 as a water cutoff pipe with a broken line or the like on the screen of the water pipe as shown in FIG. 6a.

  Moreover, the water-disruption consumer extraction part 9 of FIG. 1 is a consumer (a consumer affected by a water stop) connected to the water stop water distribution pipe 53-71 based on the output from the water stop water distribution pipe extraction part 8, respectively. Is extracted from the water distribution pipeline database 1 and transmitted to the display control unit 4. Based on the transmitted consumer information, the display control unit 4 displays all the consumers connected to the water cutoff water pipe 53-71 on the water pipes and maps in the predetermined area on the display 5 screen. The display frame indicating CQ is superimposed and displayed in a manner that is emphasized so as to be different from the display frames of other consumers (A, B, etc.) by, for example, diagonal lines. Further, the display control unit 4 displays the extracted list of consumers (see FIG. 6b) based on the output from the water cutoff consumer extraction unit 9 in the screen of the distribution pipe as shown in FIG. 6a. Display in a small window.

Next, still another operation of the first embodiment will be described with reference to FIGS. 7a and 7b. Now, assume that the user inputs a construction location indicated by reference numeral 72c in FIG. 7a by the construction location input unit 6 in FIG. Then, the closing gate search unit 7 of FIG. 1 searches for a closing valve to be closed in order to shut off the water distribution pipe 62 including the construction location 72c as follows.
First, the closing gate search unit 7 starts the distribution pipe on the left side of the distribution pipe 62 including the construction location 72c ( the upstream side of the upstream end of the end of the construction distribution pipe 62 on the contact 44 side). For each of the water pipes), the gate valves 34, 35 connected to the ends of the water pipes 57, 59 connected to the water pipe 62 via the contacts 44, 45, and the water pipe 62, the contacts 45, Recognizing the water pipe 63 and the gate valve 36 connected to the end of the water pipe 61 connected through the contact 46, the attribute information of each of the gate valves 34, 35, 36 is obtained from the water pipe database 1. refer.
Then, since each of these gate valves 34, 35, 36 has an attribute of a normal gate valve in relation to each of the water pipes 57, 59, 61, the closing gate valve search unit 7 Each gate valve 34, 35, 36 is recognized as a gate valve to be closed.

For each of the water distribution pipes), the gate valves 37, 38 connected to the ends of the water distribution pipes 64, 66 connected to the water distribution pipe 62 via the contacts 44, 45, and the water distribution pipe 62, Recognizing the gate 45 connected to the end of the water distribution pipe 68 connected via the contact 45, the water distribution pipe 63, and the contact 46, the attribute information of each of these gate valves 37, 38, 39 is the water distribution pipe. Reference is made from the road database 1.
Then, these gate valves 37, 38, 39 all have the attribute of a stop valve in relation to the water pipes 64, 66, 68 on the water pipe 62 side (upstream side). Therefore, the closing gate valve search unit 7 recognizes that each of the gate valves 37, 38, 39 is a stop valve and determines that it is not necessary to close the gate .
Therefore, next, the closing gate valve search unit 7 tries to find a gate valve further ahead ( downstream side ) of the gate valves 37, 38, 39. There is only each distribution pipe 65, 67, 69, 70, 71 at the tip (downstream side) (there is no gate valve), and these distribution pipes 65, 67, 69, 70, 71 Since the “stopping portion” is formed, the search for the gate valve to be plugged is terminated for the distribution pipe on the right side of the distribution pipe 62 in the figure.

  From the above search, the closing gate search unit 7 outputs only the gate valves 34, 35 and 36 as gate valves to be closed. Upon receiving this output, the display control unit 4 displays only the gate valves 34, 35 and 36 as gate valves to be closed on the screen of the water distribution pipe as shown in FIG. 37, 38, and 39 are presented to the user as a stop valve that does not need to be closed (for example, the characters “non-closed” are displayed in the vicinity of each of the stop valves 37, 38, 39 on the screen). .

  Moreover, the water cutoff water pipe extraction part 8 of FIG. 1 is based on the output from the said closure gate search part 7, and the construction water pipe 62 including the said construction location 72c is used as the starting point, and the both ends of the said construction water pipe 62 are used. For each of the existing distribution pipes, the distribution pipes that enter the water shut-off range are sequentially recognized and searched from the distribution pipe close to the construction distribution pipe 62 to the distribution pipe far from the construction distribution pipe 62. The search for the previous water pipe is continued, and the search is terminated when the gate valve or the stop valve to be closed is reached). As a result, the drainage water pipe extraction unit 8 has the water distribution pipes 65, 67, 69, 70, 71 forming the gate valves 34, 35, 36 to be closed and the “one kind of plug stoppers”. In order to cut off the water distribution pipe 62, the water distribution pipes 57, 59, and 61-71, which are a combination of the water distribution pipes sandwiched between the water distribution pipes and the water distribution pipes forming the “one kind of stopper portion”, Search for distribution pipes that fall within the required water outage range.

The information of the consumer who receives the information is extracted from the water distribution pipeline database 1 and transmitted to the display control unit 4. The display control unit 4 is connected to the water cutoff pipes 57, 59, and 61-71 on the water pipes and maps in the predetermined area on the display 5 screen based on the transmitted consumer information. The display frames showing all the consumers C, E, F, H, I, K, M, N, O, and Q are indicated by other diagonal lines (for example, other consumers (A, B, D, G, J, L)). , P) are displayed in a superimposed manner in an emphasized manner different from the display frame. Further, the display control unit 4 displays the extracted list of consumers (see FIG. 7b) based on the output from the water cutoff consumer extraction unit 9 in the screen of the distribution pipe as shown in FIG. 7a.

Next, still another operation of the first embodiment will be described with reference to FIGS. 8a and 8b. Now, assume that the user inputs a construction location indicated by reference numeral 72d in FIG. 8a by the construction location input unit 6 in FIG. Then, the closing gate search unit 7 of FIG. 1 searches for the closing valve to be closed in order to shut off the construction water distribution pipe 70 including the construction location 72d as follows.
First, the closing gate search unit 7 is located on the upstream side of the end of the construction water distribution pipe 70 including the construction location 72d on the left side of the construction water pipe 70 (the end of the construction water distribution pipe 70 on the contact 47, 48 side.

Then, since each of these gate valves 37, 38, 39 has an attribute of a normal gate valve in relation to each of the water distribution pipes 65, 67, 69, the closing gate valve search unit 7 Each gate valve 37, 38, 39 is recognized as a gate valve to be plugged, and here, the search for the gate valve to be plugged for the water pipe on the left side of the water pipe 70 in the drawing is finished.

Next, the closing gate search unit 7 tries to find a gate valve to be closed further downstream from the water distribution pipe 70, but there is only a water distribution pipe 71 downstream of the water distribution pipe 70. Since each of the water distribution pipes 65, 67, 69, 70, and 71 forms “a kind of stopper”, the search is terminated there.

  From the above search, the closing gate search unit 7 outputs only the gate valves 37, 38 and 39 as gate valves to be closed. Upon receiving this output, the display control unit 4 displays only the gate valves 37, 38, 39 as gate valves to be closed on the screen of the water distribution pipe as shown in FIG. The gate valve 31-36 is presented to the user as a gate valve that does not need to be closed (for example, the characters “non-plugged” are displayed in the vicinity of the gate valves 31-36 on the screen).

  Moreover, the water cutoff water pipe extraction part 8 of FIG. 1 starts from the construction water distribution pipe 70 including the construction location 72d as a starting point based on the output from the closing gate valve search part 7. For each of the existing water distribution pipes, the water distribution pipes that are in the water shutoff range are recognized and searched sequentially from the water distribution pipe close to the construction water distribution pipe 70 to the water distribution pipe farther away. The search for the distribution pipe ahead is continued, and the search is terminated when the gate valve or the stop valve to be closed is reached). As a result, the water cutoff water pipe extraction unit 8 is the water pipes 65, 67, 69, 70, 71 on the water pipe 70 side of the gate valves 37, 38, 39 to be plugged. The water distribution pipes 65, 67, 69, 70, 71 forming the “stopping part” are searched as the water distribution pipes included in the water cutoff range necessary for shutting off the water distribution pipe 70 including the construction site 72d. The display control unit 4 receives the output from the water drainage pipe extraction unit 8 and uses the water distribution pipes 65, 67, 69, 70, 71 as water cutoff pipes on the screen of the water pipe as shown in FIG. 8a. Highlight with a broken line.
