Description

  The present invention specifies the blocking range when blocking a flow channel or cable for construction of a communication facility such as a flow channel in a substance supply facility such as a water pipe of a water supply facility or a communication network of a telephone facility. The present invention relates to a method, a system, and a program.

  In a supply facility such as a water supply facility or a communication facility, some flow paths may be blocked due to an accident or construction. The generation of such a cut-off range is refrained as much as possible, and even when a cut-off is unavoidable, an effort is required to minimize the influence range (the actual cut-off range). Moreover, it is required to specify the shut-off range accurately and quickly. Therefore, for example, in an information system for managing a water supply facility (a facility information database using a GIS (geographic information system) or the like), a mechanism for quickly identifying a water stoppage range (a water stop search function) is essential.

This water cutoff search function generally specifies the water cutoff range by the following process.
(A) displaying the water pipe network on the screen;
(B) recording the specified origin in association with the pipeline network;
(C) identifying a gate valve (breaker) on the pipeline network that needs to be operated to bring the designated starting point into a shut-off state;
(D) The process of specifying the closed range on the pipeline network including the designated starting point formed by closing the specified circuit breaker as the cutoff range.

  By the way, the water cutoff range may be formed not only in the range specified in the step (d) but also outside thereof. However, in the conventional water break search, it has been substantially difficult to accurately specify the water cut off range formed outside in a practical time (there is no particular prior art document relating to the prior art) .

  The present invention has been made in view of such conventional circumstances, and the object of the present invention is to accurately set the cutoff range in a practical time in a substance supply or communication facility equipped with a channel network or a communication network. It is to provide a method, a system, and a program that can be specified.

  As a result of intensive studies to cope with the above problems, the present inventors have obtained the following knowledge. That is, in the conventional information system for water supply facility management, when trying to identify the water shut-off range outside the closed range surrounded by the gate valve to be closed, the water purification plant is started from the gate valve specified in the step (c). Search the route to the most upstream point for water supply such as water reservoirs, check the connection between the water pipe network outside the water outage range and the most upstream point, and connect to the most upstream point using this confirmation method A method of identifying an external water pipe network that cannot be confirmed as a water outage range is conceivable.

  However, in such a confirmation method, when the search target is a complicated and divergent channel network or communication network, the route to be searched becomes enormous, and in the current general PC (personal computer) environment, Due to hardware performance and basic software constraints, results cannot be obtained in a practical time.

  Therefore, as a contrivance for solving such a situation, it is conceivable to enhance the data processing environment (for example, use of parallel computing or the like) or to use a search database optimized for a water-stop search. . It is considered that such a device can be incorporated as a function of the system when the user independently constructs an information system for water supply management from the basic part.

  However, in reality, depending on economics, information technology trends, etc., users are in a situation where information systems for water supply management are realized by combining and adjusting various ready-made products. However, it is difficult to incorporate such specialized devices as described above, and even if it can be incorporated, it can be an excessive investment in terms of development and operation costs.

  Therefore, for example, in the case of water supply facilities as described above, water supply (water supply) from the most upstream point is guaranteed before (downstream) the upstream point for water supply such as a water purification plant and a distribution reservoir. By designating the facilities that are recognized as “absolute water supply facilities” and making the route search unnecessary upstream of the “absolute water supply facilities”, the number of routes required for the search is drastically reduced. It was found that the water shutoff range can be specified accurately in a practical time. This knowledge can be applied to other than water supply facilities. In other words, the present invention can also be applied to a case where a telephone supply, electricity, gas, other substance network provided with a channel network or communication network, or a blocking range in a communication facility is specified.

  That is, the present invention provides the following method for specifying the cutoff range, a specific system, and a specific program.

  According to the present invention, it is not necessary to perform a route search to the most upstream point of the channel network or the communication network by defining a new concept of “absolutely available facility” in specifying the cutoff range. It is possible to drastically reduce the route to be performed. Therefore, even when the method of the present invention is implemented on a computer as a function (blocking search function) of an information system for facility management, a use environment specialized for blocking search is not required, A result can be acquired in a practical time even in a general PC environment, and an accurate search of a blocking range in a general PC environment that has been practically impossible in the past can be performed.

  The shut-off range specifying method, the specifying system, and the specifying program of the present invention will be described with reference to the drawings, taking as an example a method for specifying a shut-off range in a water supply facility.

(A) Process or step:
First, as shown in FIG. 2, a channel network or a communication network recorded in association with geographic information is displayed on the screen. In the case of a water supply facility, as shown in FIG. 2, map data and a water pipe line on the map can be displayed by a system called a water supply GIS. That is, a map is displayed based on geographic information data, and a pipeline network, gate valve 3 (breaker), etc. are displayed on the map based on water facility data. Therefore, as means for displaying the water pipeline network recorded in association with the geographic information on the screen, the geographic information data, the water supply facility data including the pipeline network and the gate valve (breaker), and the like are associated with each other. GIS to be displayed is mentioned (hereinafter, these are collectively referred to as water supply GIS).

(B) Process or step:
Next, the designated starting point is recorded in association with the pipeline network (flow channel network or communication network). As shown in the conceptual diagram of Fig. 1, if you specify (position designation) on the water pipe network 2 as the starting point 1 for specifying the water stopping range (blocking range), this starting point 1 is recorded in association with the water pipe network 2. In the subsequent steps, the water cutoff range is specified based on the starting point 1. Usually, the starting point 1 is a place where construction is required due to a broken pipe or the like. As means for recording the starting point, there are means for designating the position on the screen such as a mouse and general recording means usually attached to the GIS.

(C) Process or step:
Next, the gate valve (breaker) on the water pipe network 2 that needs to be operated in order to set the designated starting point 1 to the water shutoff state (shutoff state) is specified. The gate valve on the water pipe network 2 that needs to be operated to bring the starting point 1 into a water-stopped state is a water pipe network including the starting point 1 when these gate valves are operated and closed. In the example of FIG. 1, the gate valves 3a, 3b, and 3c correspond to the gate valve.

  As a specific method of specifying the gate valve, it is only necessary to search backward from the starting point 1 for the pipe line leading to the starting point 1 and find the gate valve closest to the starting point 1 on each pipe line. The gate valve can be specified by using a general search function of the water supply GIS in which the position of the water pipe network and gate valve is registered on the map. If there is a gate valve that cannot be operated due to rust, corrosion, etc., find another gate valve that can be operated further upstream from the valve position. The gate valve is a gate valve that needs to be operated instead of the gate valve that cannot be operated. In this case, by specifying and recording inoperable gate valves in advance or each time, it is possible to ignore the inoperable gate valves and continue the search. As the specifying means, general search means usually attached to the GIS as described above can be used.

(D) Process or step:
Next, a closed pipe network (closed range) on the water pipe network 2 including the starting point 1 formed by closing the identified gate valves 3a, 3b, and 3c is changed to a first water cutoff range 11 (first Specified as the cutoff range). The water cutoff range 11 which is the closed range is surely in a water cutoff state because the water supply from the outside is shut off by closing the gate valves 3a, 3b and 3c. The specifying means here may be a general search means usually attached to the GIS.

(E) Process or step:
(E) Absolute water supply facilities 5a, 5b, and 5c (absolute supply possible) designated as facilities that are recognized as being guaranteed water supply from the most upstream points 4a, 4b, and 4c for supplying water This is a process of recording the facility. The steps or steps (A) to (D) are performed as a series of steps or steps, but the step (E) is performed at any stage as long as it is before the step (F) or step described later. Also good. In the case of a water supply facility, the most upstream point for supply specifically refers to a water purification plant, a water reservoir, or the like. As the absolute water supply-capable facilities 5a, 5b, and 5c, facilities that are present on the downstream side of the most upstream points 4a, 4b, and 4c and are generally recognized to be guaranteed water supply are selected.

  This facility capable of supplying water can be arbitrarily selected by a user (a water utility, etc.) of the method according to the present invention based on judgment based on empirical engineering standards. As a specific example of an absolute water supply facility, a pipe having an arbitrary pipe diameter leading to the most upstream point can be exemplified, and a pipe having an arbitrary pipe diameter is designated from pipes having a pipe diameter of 150 mm or more. It is preferable to do. Normally, pipes with such large pipe diameters are so rugged that they will not be damaged by a few earthquakes, etc. It is thought that there is not, and is suitable as an absolute water supply facility. In general, in an information system for managing water supply facilities operated by water utilities, etc., information on pipes used in local water pipeline networks managed by the water utilities, etc. Etc.) are registered in the database, and if the database is used, the above-mentioned pipeline can be easily found and designated as an absolute water supply facility.

  Note that facilities that can be designated as absolute water supply facilities are not limited to large-diameter pipes as described above, but are other regional channel networks managed by users of the method according to the present invention. Alternatively, if there is a facility that can be an absolute supply facility on the communication network, the information can be recorded in the database in advance. In this case, general recording means usually attached to the GIS can be used.

(F) Process or step:
In this process or step, (D) the water supply network outside the first water cutoff range 11 specified in the process or step is searched, and (E) the absolute water supply available facilities 5a and 5b specified in the process or step are searched. 5c is a process or step of detecting a water pipe network without connection to 5c and specifying a second water cutoff range (second cutoff range). Specifically, the pipeline is searched retrospectively from the gate valves 3a, 3b, 3c specified in the step (C) or step, and the presence / absence of connection with the absolute water supply available facilities 5a, 5b, 5c is checked. In the example of FIG. 1, first, the water pipe network 12 from the gate valve 3b to the terminal end 6 of the pipe is detected in this process or step as not connected to the absolute water supply facility 5a, 5b, 5c, It is specified as the second water cutoff range. Further, another gate valve 7 that is in a closed state exists at a position retroactive to the flow path from the gate valve 3c. By this gate valve 7, a water pipe line from the gate valve 3c to the gate valve 7 is provided. Since the network 13 is also disconnected from the absolute water supply facility 5c, this water pipe network is also detected as not connected to the absolute water supply facility in this process or step, and is specified as the second water cutoff range. Is done. The specification of the second water cutoff range can be easily performed by using the same means as the specification of the first water cutoff range described above if an absolute water supply facility is specified and recorded.

  In this way, in addition to the first water cutoff range 11 identified in the step or step (D), the water pipe networks 12 and 13 are specified as the second water cutoff range, whereby the complete water cutoff range is accurately determined. Can be specified.

  As described above, in the method for specifying the water cutoff range of the present invention, it is not necessary to perform a route search to the most upstream point for water supply as in the prior art in specifying the complete water cutoff range. If a route search is made to a facility that allows absolute water supply to the nearer side (downstream side), a complete water shutoff range can be specified, and the route to be searched can be greatly reduced.

  If there is a facility that is recognized as blocking the water supply from the facility 5c capable of absolute water supply, such as the gate valve 7 in the closed state in FIG. In (F) process or step, when searching for the pipeline, search for the water pipeline network ahead (upstream side) of the channel cutoff facility (gate valve 7) is stopped. It is preferable. By carrying out like this, the path | route which should be searched in order to specify the water cutoff range can be reduced further.

  In general, in an information system for managing water supply facilities operated by a water utility, etc., information (position, opening / closing status, etc.) of gate valves used in the local water pipeline network managed by the water utility, etc. For example, when a gate valve that is closed as described above is to be designated as a flow path shut-off facility, the above partition is used by utilizing the database. Valves can be easily found and designated as a channel blocking facility.

  The facilities that can be designated as the flow path blocking facility are not limited to the gate valves that are in the closed state as described above. If there is a facility that can be a channel blocking facility on the road network or communication network, it is desirable to record the information in a database in advance.

  EXAMPLES Hereinafter, although this invention is demonstrated further in detail based on an Example, this invention is not limited to these Examples.

  As part of the functions included in the information system for water supply management using GIS (water outage search function), a system for executing the method for specifying the water outage range according to the present invention on a PC is actually constructed. The water outage range was identified.

  First, the screen shown in FIG. 2 is displayed. FIG. 2 is a screen for designating the start point of the water stop search in this system. This screen shows the location of the water pipe network and its ancillary facilities on the map. By specifying the location of the construction site to be the starting point of the water outage search on the screen with a mouse or the like, A search for a pipe line leading to the starting point 1 is performed, and the gate valve 3 on the water pipe network that needs to be operated in order to bring the starting point 1 (construction site) into a water-stopped state is specified.

  FIG. 3 is a screen for designating an absolute water supply facility, and shows a state where a pipeline is designated from various facilities registered in advance as candidates that can become an absolute water supply facility. . FIG. 4 is a screen for further specifying the conditions for the pipe line designated as the absolute water supply facility in FIG. 3. Here, the pipe diameter of 250 mm or more (less than 7777 mm) is designated as a condition. Show.

  FIG. 5 is a screen for designating a flow path blocking facility, and here shows a state in which a gate valve is designated from various facilities registered in advance as candidates that can become flow path blocking facilities. . FIG. 6 is a screen for further specifying the conditions for the gate valve specified as the flow path blocking facility in FIG. 5. Here, the gate valve is specified as a condition that the gate valve is in a hay (closed) state. Indicates the state.

  As described above, after specifying the conditions necessary for the water-stop search on each screen, an instruction to start the search was issued on the water-stop search menu screen shown in FIG. FIG. 8 is a screen display of the result of the water break search. In FIG. 8, a thick line indicates a water pipe network that is a closed range by operating the gate valve 3 specified first to be in a closed state, and is specified as a first water cutoff range. In addition, the dotted line indicates the water pipe network detected as a result of the search as having no connection to the facility capable of absolute water supply, and the water pipe network specified as the second water cutoff range. is there. The total of these water pipe networks is specified as the complete water outage range.

  Using this system, the water shut-off range was specified for the three actual water pipeline networks (A, B, C) under the conditions shown in Table 1, with the predetermined position as the designated location (starting point). The results are shown in Table 1. In Table 1, the conventional water break search means a search for only the first water cut range, and the water break search including the possibility of water supply means a search for the first and second water cut ranges. As shown in Table 1, when the first and second water shut-off ranges were searched with this system, an accurate water shut-off range could be specified in about 10 to 70 seconds. Moreover, it was shown that the search time depends on the number of pipeline branches in the search range rather than the distance to the absolute water supply facility. Although this system was not used and only the conventional water supply GIS search system was used, an attempt was made to search the first and second water shut-off ranges. However, the time that could be substantially measured was exceeded and the time could not be measured. .

  The present invention has been described by taking a water supply facility as an example. it can.
