Description

  The present invention relates to a water supply operation support information display system that provides guidance for operation in a monitoring control system that performs monitoring control of a water supply plant having a water supply system.

  The component facilities managed by the waterworks company range from the facilities in the water treatment plant to the piping facilities in the city area. Therefore, when monitoring and controlling a water supply plant, a method is adopted in which a central monitoring control room is provided, a central monitoring control panel is installed, and the entire plant is collectively monitored and controlled.

  In general, drinking water produced at a water purification plant is stored in a storage tank called a distribution reservoir, and is supplied from there to a city area through a distribution pipe network. When distributing water to distant places and high places, water is delivered through multiple reservoirs, and in large-scale places, it passes through more than 10 reservoirs to reach the farthest reservoir. There is also a case.

  The waterworks plant operator predicts demand fluctuations in each distribution area, and keeps the water storage in all distribution reservoirs within an appropriate range, so that the water supply system, between the distribution reservoirs, between the distribution reservoirs, and the distribution reservoirs in the transmission system. It is required to control the water flow rate. However, since the amount of stored water and the amount of demand change from moment to moment, the operator must correctly judge the situation at that moment and select an appropriate operation method according to the situation.

  An operation support apparatus has been introduced as an aid for such a complicated driving situation. The operation support apparatus provides information that is used as a judgment material for an operator under a situation where selection of an operation is required, and includes various prediction functions and simulation functions.

  As functions realized by the operation support device, there are a water supply scheduling function and a reservoir water level simulation function. The water supply scheduling function is the one that the computer automatically schedules the operation of the water flow rate based on the demand forecast value from each distribution reservoir. The distribution water level simulation function is the operation schedule and distribution reservoir calculated by the water supply scheduling function. The transition of the water level is expressed using an animation display on a table, a trend graph, or a system diagram.

  As such an operation support apparatus, for example, there is a (power system contraction) display processing apparatus disclosed in Patent Document 1.

JP 2009-247135 A

  The display method in the water supply scheduling function of the conventional operation support apparatus displays the operation schedule information output by the water supply scheduling function for each component facility or in a list of all component facilities. Therefore, it is suitable to understand the contents by focusing on the movement of the flow rate of one distribution reservoir or pipeline, but the movement of water seen in the whole system and the situation of certain components There was a problem that it was difficult to grasp from a macro viewpoint such as the influence on the component equipment.

  In particular, when the scale of the transmission system subject to water transmission scheduling and distribution reservoir water level simulation is large and the pipeline connection between the distribution reservoirs is complicated, the effect becomes significant, and the operator outputs the output calculated by the operation support device. There is a problem that it is difficult to judge whether the result (operation status by water supply scheduling and distribution reservoir water level simulation) is appropriate.

  The display processing apparatus disclosed in Patent Document 1 automatically creates a reduced drawing of the entire system for the purpose of displaying the power flow of the entire power system facility. Even when there are many display elements on the system diagram, by reducing the system diagram, it is possible to secure the space necessary for display and to follow the tide of the entire system without impairing visibility. ing.

  However, when applying the technique used by the display processing device of Patent Document 1 to the water level simulation display of the distribution reservoir in the water transmission system, it is necessary to select whether or not to perform contraction display for each component facility on the drawing of the water transmission system There are still issues. When performing contracted display in the water level simulation display of the reservoir, the operator needs to select the area for the contracted display from the output results indicating the operating status of the water transmission system. If the movement is not understood, it is impossible to determine which area should be reduced. In order to be able to select an appropriate display, it is necessary to wait until the operator's judgment ability is improved and understand the movement of the entire water transmission system, and as a result, it is difficult to grasp from a macro viewpoint. The problem of the display processing device 1 has not been solved.

  The present invention has been made to solve the above-described problems, and makes it easy to grasp the movement of the entire target water transmission system, and makes it easy to determine whether the operation schedule calculated by the system is appropriate. The purpose is to obtain an operation support information display system.

<Embodiment 1>
The water supply operation support information display system according to the first embodiment is a display in which the output result of operation scheduling can be easily understood by the user so as to realize one function (operation operation guidance) for the operation support device for water supply having the target water transmission system. It is for displaying using a method. In particular, it is assumed that scheduling is performed for large-scale water distribution systems where there are multiple reservoirs (water storage tanks) and water pumps. In addition, the target water transmission system has a plurality of reservoirs, a plurality of pumps, and a plurality of pipelines as constituent facilities, and any one of the plurality of pumps is used between the plurality of reservoirs. They are supplied through one of the pipelines.

  1 is a block diagram showing the configuration of a water supply operation support information display system according to Embodiment 1 of the present invention.

  As shown in FIG. 1, the system according to the first embodiment includes an input / output device 110, a scheduling device 120, an operation (operation) schedule database 131, an operation model database 132, an equipment model database 133, an attention degree database 134A, and an attention location determination. The apparatus 140A includes an evaluation value determination unit 141, a display drawing creation apparatus 170, and a display apparatus 180.

  The scheduling device 120 is a device that performs an internal calculation in a water supply schedule function for obtaining operation schedule information. The scheduling device 120 receives the operation model information D32 and the equipment model information D33. The equipment model information D33 is information related to the equipment model such as pipe connection information and equipment specifications registered in advance in the equipment model database 133 and indicating connection contents between a plurality of pipes. The operation model information D32 is information relating to operation settings such as operation constraint conditions and operation targets registered in advance in the operation model database 132. The operation target is provided with a plurality of criteria (indexes) such as minimizing power consumption and minimizing fluctuations in the water flow rate.

  Based on the operation model information D32 and the equipment model information D33, the scheduling device 120 uses a mathematical programming method or the like to calculate a flow rate setting value or the like of a device that performs flow rate control of a pipeline such as a water pump or a flow rate adjustment valve, Operation schedule processing for obtaining operation (operation) schedule information D31 for instructing information related to the operation schedule of the water transmission system and outputting it to the operation schedule database 131 is executed. At this time, when calculating the flow rate setting value, a value is selected so that the evaluation value of the operation target becomes an optimum value throughout the operation.

  In general, when the operation scheduling process is executed, various parameter settings included in the above-described operation target and operation constraint conditions indicated by the operation model information D32 are possible. By changing those parameter values, The contents of the output operation schedule information D31 can be changed. The input device 110 performs parameter setting necessary for performing the operation scheduling process, and parameter setting can be performed by giving the parameter information D10 to the scheduling device 120 by a user operation.

  Hereinafter, the parameter information D10 will be described as an example. For example, a case is assumed in which a condition shown in the following expression (1) is given as an operation constraint condition specified by the operation model information D32.

  In the above equation (1), parameter information D10 indicating the lower limit water level Pmin and the upper limit water level Pmax can be given to the scheduling device 120. Therefore, the lower limit water level Pmin and the upper limit water level Pmax in the equation (1), which are operation constraint conditions, can be appropriately changed by the parameter information D10.

  The operation schedule database 131 registers the operation schedule information D31 output from the scheduling device 120. As will be described in detail later, the operation schedule information D31 includes information obtained by combining the calculated water supply flow rate set value for each unit time, the reservoir storage amount, and the operation target evaluation value.

  FIG. 2 is an explanatory diagram schematically showing the contents of the operation schedule information D31 registered in the operation schedule database of the water supply operation support apparatus. The operation schedule information D31 is managed in units of simulation ID information D21, which is an identifier of scheduling calculation, and simulation time information D22 and equipment type information D23 which is information for identifying the type of constituent equipment on the water transmission system model, Each piece of equipment type ID information D24, which is information for identifying the same kind of constituent equipment, is provided. And for every equipment type ID information D24, it has plan value information D25 and evaluation value information D26 (D26a-D26c).

  Both the plan value information D25 and the evaluation value information D26 are values calculated by the scheduling device 120. In the plan value information D25, information related to the operation of the component equipment such as the water supply flow rate setting value and the reservoir reservoir amount for each unit time is registered. Is done. In the evaluation value information D26 (D26a to D26c), an evaluation value is registered for each evaluation index of the operation target.

In the example shown in Figure 2, the water level of the reservoir (ID: 1) is 2.5m, the water level of the reservoir (ID: 2) is 2.0m, and the water level of the reservoir (ID: 3) is 2.3m. The pump (ID: 1) water supply amount is 100 m ³ / h, the pump (ID: 2) water supply amount is 120 m ³ / h, and the pump (ID: 3) water supply amount is 150 m ³ / h. Value information D25 is shown.

  Moreover, the evaluation A shown by the evaluation value information D26a is a pump water supply amount smoothing index value, and indicates pass / fail in the order of 0 (best), 1,. The evaluation B indicated by the evaluation value information D26b is a pump power consumption index value, which indicates pass / fail in the order of 0 (best), 1, 2,. The evaluation C indicated by the evaluation value information D26c is a reservoir water level index value, and indicates pass / fail in the order of 0 (best), 1, 2, 3,.

  Therefore, from evaluation C, the reservoir with ID: 3 has a high water level (bad “3”), and the reservoir with ID: 2 has a low water level evaluation value (a little good “1”). From B, it is recognized that the pumps with ID: 1 and ID: 2 have the same index value ("1", "2") for both the smoothing evaluation value and the power consumption. The pumps with ID: 1 and ID: 2 It is recognized that the power consumption ("2") is worse than the smoothing evaluation value ("1"). With regard to the smoothing evaluation value and power consumption, the ID: 3 pump has ID: 1 and ID : It is recognized that the evaluation value is smaller (good “0”) than the pump of 2.

  The attention point determination device 140A has an evaluation value determination unit 141 inside. The evaluation value determining unit 141 inputs the operation schedule information D31 registered in the operation schedule database 131 and the operation model information D32 registered in the operation model database 132, and each component facility (distribution reservoir, For water pumps, pipelines, etc.), the bottleneck component equipment (equipment with a high degree of influence) that is determined to be a bottleneck that the impact on the operational target mentioned above will be a major bottleneck according to the first standard The bottleneck determination process for obtaining the attention level information D34A (first attention level information) to be performed is executed.

  Specifically, the evaluation value determination unit 141 is registered in the operation model database 132, the plan value information D25 and the evaluation value information D26 defined by the operation schedule information D31 registered in the operation schedule database 131, and the like. Operation model information D32 is acquired. Then, the evaluation value determination unit 141 has a large influence on the evaluation index that is regarded as important in the execution of the operation scheduling process among various factors for realizing the operation target, and has a larger degree of influence than the other component facilities. The above-described bottleneck component equipment is extracted as a high-impact constituent equipment, and the attention level information D34A in which the attention degree value of the high-impact constituent equipment is set to the highest is obtained. Execute.

  The details of the bottleneck determination process performed by the following evaluation value determination unit 141 will be described in detail. Examples of operation targets in the operation scheduling process are as follows: Condition (1) `` Smooth the pump water volume as much as possible '', Condition (2) `` Minimize pump power consumption '', Condition (3) `` Raise the reservoir water level And the like. As an operation target value based on these conditions (1) to (3), for example, a calculation formula that minimizes the operation target value f as shown in the following formula (2) is conceivable.

  In Equation (2), G1, i (x), G2, i (x) and G3, j (x) are operation target values f including C1 to C3 are operation targets indicated by the operation model information D32. G1, i (x) is a formula for calculating the smoothing evaluation value based on the amount of water delivered by each pump per unit time x, and G2, i (x) is the amount of power consumption based on the amount of water delivered by each pump per unit time x. G3, j (x) is a formula for calculating an evaluation value based on the water level of each drainage basin at unit time x.

  Therefore, after the smoothing evaluation value and the power consumption are obtained for each pump i by the equation (2), the smoothing evaluation value calculation equation G1, i (x) and the power consumption calculation equation G2, i (x) The multiplication factor C1 and the power consumption factor C2 are multiplied. Further, after the water level evaluation value is obtained for each reservoir j by the water level evaluation calculation formula G3, j (x) in the formula (2), the water level coefficient C3 is multiplied by the drainage pond water level coefficient.

  Then, the evaluation value determining unit 141 {C1, G1, i (x) / f}, {C2 for each pump i and each reservoir j constituting the water transmission system when minimizing the operation target value f. G2, i (x) / f} and {C3 · G3, j (x) / f} are obtained as an evaluation index emphasizing the attention level comparison index, and the pump x or the arrangement having the maximum attention level comparison index The water pond y can be determined as a bottleneck component facility (a facility component with a large influence). That is, the component facility that takes the attention level comparison index that has the greatest degree of influence on the operation target value f indicated by the operation model information D32 is determined as the bottleneck component facility.

  Thus, in the example using Formula (2), the evaluation value determination part 141 is {C1 * G1, i (x) / f} among all the pumps and all the reservoirs which comprise a water supply system. , {C2 · G2, i (x) / f} and {C3 · G3, j (x) / f} are the bottleneck components (high impact) The bottleneck determination process for obtaining the attention level information D34A indicating the bottleneck component facility is executed. That is, in the case of the example using Expression (2), the first reference for determining the bottleneck constituent facility in the bottleneck determination process is the reference for determining the constituent facility having the maximum attention degree comparison index. .

  The attention level information D34A obtained by executing the bottleneck determination process by the attention point determination device 140A is registered in the attention level database 134A as registered attention level information R34.

  As described above, the evaluation value determination unit 141 serving as the component facility influence determination unit instructs the operation model information D32 among the plurality of component facilities constituting the water transmission system based on the operation model information D32 and the operation schedule information D31. Attention level information D34A (first attention level information) that indicates a bottleneck configuration facility (a configuration facility with a high impact level) that is a configuration facility that is determined to have a large influence on the operation target in accordance with the first standard is obtained. ing.

  The display drawing creation device 170 is a device that performs a system display process that is an internal process in the distribution reservoir water level simulation function. The display drawing creation apparatus 170 creates display drawing information D70 using information D31, D32, and D33 registered in the operation schedule database 131, the operation model database 132, and the equipment model database 133. As an example of a display screen on the display device 180 based on the display drawing information D70, the transition of the operation schedule and the reservoir water level specified by the operation schedule information D31 is displayed using a table, a trend graph, or an animation display on the system drawing. The method of expressing is mentioned.

  Then, when the registered attention level information R34 registered in the attention level database 134A includes the attention level information D34A, the display drawing creation apparatus 170 creates a bottleneck configuration in the water supply system in the water supply system based on the attention level information D34A. The above-described system display process for giving the display drawing information D70 to the display device 180 so as to display the facility on the display device 180 in a different manner from the others is executed.

  Based on the display drawing information D70 created by the display drawing creation device 170, the display device 180 displays the drawing so that the user can visually recognize it. For example, for a water pump, distribution reservoir, or pipeline corresponding to a bottleneck component facility, an enlarged display, a color change or the like is highlighted.

  In addition, the said 1st reference | standard determined as a bottleneck constituent equipment in the bottleneck determination process which the evaluation value determination part 141 performs is not limited to the example mentioned above. For example, a first threshold value for comparison is provided in advance, and an evaluation index to be emphasized in the operation target to be compared with the first threshold value (the attention level comparison index using Formula (2), etc.) is the first. You may use the threshold value comparison determination method which determines all the structural equipment which exceeded the threshold value as a bottleneck constituent equipment. In the threshold comparison method, the first criterion is that the evaluation index to be emphasized is larger than the first threshold. The first threshold value can be set by the user from the outside with respect to the evaluation value determination unit 141.

  In addition, regarding the evaluation index to be emphasized such as the attention degree comparison index, a component facility having a value within one or more bottleneck selection numbers in order from the maximum value is set as a bottleneck component facility, and the number of bottleneck selections is changed. Thus, a step determination method may be used in which the constituent equipment is changed in the highlighted display continuously (stepwise) on the display device 180 under the control of the display drawing creation device 170. In the stage determination method, the first criterion has values within the number of bottleneck selections in order from the highest evaluation index to the highest value. The number of bottleneck selections can be set by the user from the outside with respect to the evaluation value determination unit 141.

  According to the water supply operation support information display system of the first embodiment, when the evaluation value determination unit 141 adopts the threshold value comparison determination method, the user uses the first threshold value from the outside to the evaluation value determination unit 141, for example. By changing the value of, the range of emphasis display (equipment with a high influence level) can be arbitrarily changed. Therefore, in a state where the user does not understand the driving scheduling status displayed on the display device 180, the evaluation index becomes a bottleneck by setting the first threshold value high and limiting the highlighted range. It is possible to easily identify the constituent equipment. After that, by gradually setting the first threshold value low, the highlighted portion spreads over the entire system according to the order of interest.

  In addition, even in large-scale water distribution systems where there are multiple reservoirs and water pumps, the flow is confirmed according to the ranking of the evaluation index values that are important, such as the attention level comparison index, using the above-mentioned stage determination method. By doing so, it becomes easy to grasp the movement of the entire large water transmission system, and it is possible to easily determine whether or not the output result calculated by this system is appropriate.

  As described above, the evaluation value determination unit 141 that is a large influence degree determination unit includes operation model information among a plurality of constituent facilities in a target water transmission system including a plurality of reservoirs, a plurality of pumps, and a plurality of pipelines. Attention degree, which is first attention degree information indicating a bottleneck constituent equipment (a high influence degree constituent equipment) that is determined to have a large influence on the operation target value f indicated at D32 along the first reference. Information D34A can be obtained.

  As a result, the display drawing creation device 170 displays the bottleneck component equipment on the display device 180 in a different mode (highlighting display etc.) from the other based on the attention level information D34A, thereby making the entire target water supply system. It is easy to grasp the movement of the vehicle, and it is easy to determine whether the output result of the operation schedule status calculated by the operation support information display system is appropriate, and finally has a target water transmission system The safety of the water supply plant can be increased.

  In addition, when the operation target value f shown in Expression (2) is used, G2, i (x), which is an instruction index for “minimizing power consumption”, is included, so that power consumption is reduced. Water supply operation can be performed.

<Embodiment 2>
FIG. 3 is a block diagram showing a configuration of a water supply operation support information display system according to Embodiment 2 of the present invention.

  In order to understand the schedule situation indicated by the operation schedule information D31 obtained by the scheduling device 120, in addition to the bottleneck component equipment having a high value of the evaluation index to be emphasized such as the attention degree comparison index, the entire pipeline system It is important to understand the main water flow.

  In general, a plurality of pipelines, which are components of the water transmission system, branch away from the water purification plant, and the pipeline flow rate tends to be small. For this reason, when attention is paid only to the value of the flow rate, a pipe line close to the water purification plant tends to be selected, and it is difficult to grasp the flow of water as seen in the entire water supply system. In order to grasp the main water flow in the entire pipeline system consisting of a plurality of pipelines, it is necessary to confirm the flow rate while referring to the route information from the water treatment plant to the terminal reservoir.

  Therefore, the attention point determination device 140B of the second embodiment is characterized by further including a flow rate determination unit 142 in addition to the evaluation value determination unit 141.

  The flow rate determination unit 142 uses the plan value information D25 (see FIG. 2) in the operation schedule information D31 registered in the operation schedule database 131 and the pipeline connection information in the equipment model information D33 registered in the equipment model database 133. get. Next, on the basis of the above-mentioned pipeline connection information, for each pipeline route from the most upstream water treatment plant to the terminal reservoir, the route length and flow rate of each pipeline are obtained. Attention level information D34B that is set so as to increase the degree of attention is obtained for a pipeline having a relatively large flow rate.

  That is, the flow rate determination unit 142 calculates the path length and flow rate of each of a plurality of pipelines constituting the water transmission system based on the plan value information D25 (operation schedule information D31) and the pipeline connection information (equipment model information D33). Then, attention level information D34B (second attention level information) indicating a specific flow rate large pipe having a specific flow rate that is a flow rate with respect to the path length among the plurality of pipelines is larger than a second threshold for specific flow rate comparison is obtained. . The second threshold value can be set by the user or the like for the flow rate determination unit 142.

  The attention level information D34B is registered in the attention level database 134B as at least a part of the registered attention level information R34. Therefore, in the second embodiment, the registered attention level information R34 may include attention level information D34A and D34B.

  Then, when the registered attention level information R34 includes the attention level information D34B, the display drawing creation apparatus 170 displays the large specific flow rate pipeline in the water supply system in a manner different from other pipelines based on the attention level information D34B. The process displayed on 180 is executed as a system display process.

  When the flow rate determination unit 142 calculates the attention level information D34B, the user can arbitrarily change the determination criterion for the specific flow rate large conduit by changing the value of the second threshold value for specific flow rate comparison. For example, if the second threshold value is set high, only the main pipe having a large specific flow rate can be highlighted on the display device 180 under the control of the display drawing creation device 170 as the large specific flow rate pipe. By gradually lowering the threshold value of 2, the pipeline highlighted on the display device 180 spreads over the entire water supply system. By confirming the main water flow, there is an effect that it becomes easy to grasp the movement of the entire large-scale water transmission system.

  FIG. 4 is an explanatory diagram showing a display example of the operation schedule status displayed on the display device 180 by the display drawing creation device 170. The display similar to the display example in FIG. 4 is also possible in other embodiments (Embodiment 1, Embodiment 3 and Embodiment 3 described later).

  The display example of the water supply system shown in FIG. 4 includes pipe line icons 21 to 28 that indicate pipe lines, pump icons 31 to 38 that indicate water pumps, and water tank icons 11 to 17 that indicate water reservoirs. .

  The arrows of the pipe line icons 21 to 28 mean the flow direction, and the thickness represents the magnitude of the flow rate. In addition, in FIG. 4, the thickness of the pipe line icons 21-28 is an absolute value, and is not a specific flow rate.

  The diagonally hatched areas of the reservoir icons 11 to 17 are the water storage amount icons V11 to V17, and the water storage amount icons V11 to V17 mean the water storage amount of the water reservoir icons 11 to 17, respectively.

  The thickness of the pipeline icons 21 to 28 and the size of the display area of the water storage amount icons V11 to V17 vary with the flow rate change and the water storage amount change indicated by the operation schedule information D31.

  The pipe line icons 21, 23 and 27 and the pipe line icon 24 are examples in which highlighting is performed by changing the color of the icon (indicated by dark hatching in the drawing).

  At this time, the attention location determination device 140 has the attention level information D34A by the evaluation value determination unit 141 and the attention level information D34B by the flow rate determination unit 142 as coefficient values indicating weighting for the attention level information D34A and the attention level information D34B. It can be set by the user from the outside.

  Accordingly, the user emphasizes the attention level information D34A according to needs and highlights only the component facilities that are determined that the attention level comparison index becomes a bottleneck according to the first reference, or the attention level information D34B. Emphasis can be given to highlighting only the main water flow in the entire pipeline system, or emphasis can be placed on the attention degree information D34A and D34 in both cases, and the emphasis target can be arbitrarily changed. .

  As described above, the flow rate determination unit 142 instructs the specific flow rate large pipeline that has been determined that the specific flow rate, which is the flow rate with respect to the path length, of the plurality of pipelines is greater than the second threshold value for specific flow rate comparison. The attention level information D34B, which is the second attention level information, can be obtained.

  As a result, in the display drawing creation device 170, in addition to the bottleneck component equipment of the first embodiment, the large specific flow rate conduit can be displayed on the display device 180 in a different manner from the other based on the attention level information D34B. Therefore, it becomes easy to grasp the movement of the entire water transmission system, and it is possible to more easily determine whether the output result of the operation schedule status calculated by the operation support display system is appropriate.

<Embodiment 3>
FIG. 5 is a block diagram showing a configuration of a water supply operation support information display system according to Embodiment 3 of the present invention.

  When the evaluation value determination unit 141 determines that a certain component facility is a bottleneck component facility in accordance with the first reference, the reason is that the case is caused by the equipment specification of the bottleneck component facility, and the bottleneck This may be due to the circumstances surrounding the component equipment. For example, when there is a device with a large number of pump start / stop switching times, the pump output set value may be a factor, or the pump destination / source water reservoir may be the factor. Exists.

  In addition to the configuration of the attention point determination device 140B of the second embodiment, the attention point determination device 140C of the third embodiment further includes a factor determination unit 143.

  The factor determination unit 143 acquires the attention level information D34A calculated by the evaluation value determination unit 141 from the attention level database 134, and identifies the component facility whose attention level comparison index is a bottleneck. Next, the pipeline connection information in the equipment model information D33 registered in the equipment model database 133 is acquired, and the peripheral constituent equipment of the equipment that becomes the bottleneck is specified. For the peripheral configuration equipment, the operation schedule information D31 and the operation model information D32 are used, and the plan value information D25 (operation schedule information D31) of the peripheral configuration equipment is a boundary in the operation constraint condition (determination formula) indicated by the operation model information D32. Judge whether it is distributed near the value. If the planned value information D25 of the peripheral component equipment is distributed in the vicinity of the boundary value of the operation restriction condition, the peripheral component equipment is noted as a warning component equipment because it may have affected the bottleneck component equipment. The attention degree information D34C is obtained by setting the degree high.

  FIG. 6 is a graph showing an example of determining whether the peripheral component facility is near the boundary value of the operation constraint condition. In FIG. 6, the case where the water pump (icon) 34 shown in FIG.

  The figure (a) shows the change in the pump flow rate Q34 of the water pump 34, which is a high-impact component, and the figure (b) shows the drain water level P14 of the drainage basin (icon) 14 downstream of the water pump 34. FIG. 4C shows the change of the drainage basin water level P13 of the distribution reservoir (icon) 13 upstream of the water pump. Further, the expression (1) described in the first embodiment is adopted as the operation constraint condition.

  As shown in the figure (a), in the evaluation value deterioration time zone TB where the pump flow rate Q34 of the pump 34 becomes large, as shown in the figure (b), the drainage pond water level P14 is set slightly higher than the lower limit water level Pmin. If it falls below the reference lower limit water level PL, it is determined that it is distributed near the boundary value (near the lower limit water level Pmin). In this case, the distribution reservoir 14 upstream of the drainage pond water level P14 is determined to be a vigilance component and the degree of attention is set high.

  Similarly, in the evaluation value deterioration time zone TB, the drainage pond water level P13 does not exceed the reference upper limit water level PL set slightly lower than the upper limit water level Pmax as shown in FIG. It is determined that it is not distributed in the vicinity of Pmax). In this case, the distribution reservoir 13 downstream of the drainage pond water level P13 is not required to be a cautious component, and the degree of attention is not set high.

  As described above, the factor determination unit 143 is based on the attention level information D34A and the equipment model information D33, and is located upstream or downstream of the bottleneck constituent equipment (for example, a water pump) and is a different type of constituent equipment from the bottleneck constituent equipment. At least one peripheral component facility (for example, the upstream and downstream distribution reservoirs of the water pump) is extracted. Then, the factor determination unit 143 determines whether or not each of the at least one peripheral component facility is in a cautionary state that may not satisfy the operation constraint condition specified by the operation model information D32, and the at least one peripheral component facility is determined. Attention level information D34C is obtained that indicates a warning-required component facility that is a facility that has been determined to be in a required warning state among the two peripheral component facilities.

  The attention level information D34C is registered in the attention level database 134B as at least part of the registered attention level information R34. Therefore, the registration attention level information R34 may include attention level information D34A to D34C.

  Then, when the attention level information D34C is registered in the registered attention level information R34 of the attention level database 134 as the system display process, the display drawing creating apparatus 170 performs the above-mentioned requirement in the water supply system based on the attention level information D34. The alert component equipment is displayed on the display device 180 in a manner different from other similar component equipment.

  In the first embodiment, the user may have another type of upstream configuration equipment affecting the bottleneck configuration equipment determined by the evaluation value determination unit 141, or may be another type of downstream configuration equipment. Judgment must be made as to whether it is influencing.

  In the third embodiment, by using the attention level information D34C by the factor determination unit 143, it is possible to easily recognize the influence degree of the peripheral configuration equipment by focusing on the alert configuration equipment from the display content on the display device 180. Can do. As a result, it is possible to simplify the work of verifying the data related to the peripheral configuration equipment of the bottleneck configuration equipment one by one, and it becomes easy to determine whether the output result calculated by this system is appropriate.

  As described above, the factor determination unit 143 in the water supply operation support information display system of the third embodiment may not satisfy the operation constraint condition among at least one peripheral component facility located upstream or downstream of the bottleneck component facility. Attention level information D34C is obtained as third attention level information for instructing a warning-requiring configuration facility that is a facility that has been determined to be in a certain warning state. That is, the factor determination unit 143 investigates the operation status of the peripheral component equipment adjacent to the bottleneck component facility, and determines whether the peripheral component facility has an influence on the bottleneck component facility.

  As a result, in the display drawing creation device 170, in addition to the bottleneck component equipment, the warning component facility existing upstream or downstream of the bottleneck component facility is displayed in a mode different from the other, based on the attention level information D34C. Since it can be displayed on the apparatus 180, the factor analysis of why the bottleneck constituent equipment has a great influence is facilitated, and the movement of the entire water supply system can be easily grasped.

  Also in the third embodiment, as in the case of the second embodiment, the user uses the third for determining whether or not there is a distribution near the boundary value with respect to the attention level information D34C calculated by the factor determination unit 143. The threshold value (value corresponding to the reference lower limit water level PL and the reference upper limit water level PL in FIG. 6) can be set by the user from the outside, so that the user appropriately changes the second threshold value, thereby allowing the display device 180 to It is possible to arbitrarily change the range of the warning-requiring component equipment to be highlighted.

  In addition, the attention location determination device 140 weights the attention level information D34A to D34C, so that the attention level calculated by the evaluation value determination unit 141 and the flow rate determination unit 142 during the system display processing by the display drawing creation device 170. The information D34A to D34C can be highlighted and displayed, or the attention level information D34A to 34C can be displayed individually.

<Embodiment 4>
FIG. 7 is a block diagram showing a configuration of a water supply operation support information display system according to Embodiment 4 of the present invention.

  In a large-scale water distribution system in which there are more than 10 distribution reservoirs and pumps that constitute the water supply system, when displaying the operation schedule status as shown in FIG. However, there are cases where the entire water distribution system diagram does not fit, and there are cases where the pipeline route has a complicated shape, which hinders understanding of the flow of the entire system.

  In view of this, the fourth embodiment is characterized in that a drawing dividing device 150 and a display data calculation device 160 are further provided, and a reduced display of the water supply system is made possible on the display device 180.

  The drawing dividing device 150 applies to all the facilities of the water transmission system indicated by the equipment model information D33 based on the registered attention level information R34 (at least one of the attention level information D34A to 34C) registered in the attention level database 134. On the other hand, a grouping process for grouping a part of surrounding constituent facilities with a low degree of attention is performed on the basis of the constituent equipment with a high degree of attention. Hereinafter, the grouping process executed by the drawing dividing apparatus 150 will be described in detail.

  The drawing dividing device 150 is a judgment criterion (for example, a judgment criterion (first judgment criterion) by the evaluation value judgment unit 141 according to the first embodiment) that can be variably set by a user in advance from all the component facilities constituting the water transmission system. Based on the registered attention level information R34 in accordance with the determination criterion using the second threshold by the flow rate determination unit 142 of the second embodiment or the determination criterion using the third threshold by the factor determination unit 143 of the third embodiment). Identify a facility with a high degree of attention (a facility with a high degree of attention).

  Then, the drawing dividing device 150 further specifies the component equipment located upstream or downstream of the specified high attention degree component equipment, and sets these together as a non-grouping element. After that, the drawing dividing apparatus 150 performs grouping to classify the constituent facilities other than the non-grouping elements into at least one group. At this time, group setting is performed with restrictions so that the pipeline route does not circulate, and grouping information D50 for instructing the group setting content is obtained. The grouping information D50 is given to the display data arithmetic device 160 at the next stage and is also stored in the equipment model database 133.

  As described above, the drawing dividing device 150 which is a grouping device is configured to configure the water supply system based on the registered attention level information R34 (at least one of the attention level information D34A to D34C) registered in the attention level database 134. A grouping that determines a non-grouping element for each group and obtains grouping information D50 set in the same group under the constraint that no cyclic route is generated for the components other than the non-grouping element (there is no route to return to the same reservoir) Execute the process.

  The display data calculation device 160 executes reduction calculation processing for creating reduced operation schedule information D31r for reduced drawings from the operation schedule information D31 according to the grouping information D50 calculated by the drawing dividing device 150. Hereinafter, the reduction calculation process executed by the display data calculation device 160 will be described in detail.

  When there are a plurality of reservoirs in the same group with reference to the grouping information D50 with respect to the operation schedule of the water transmission system indicated by the operation schedule information D31, the display data calculation device 160 has a total capacity of the plurality of reservoirs. And re-define as one virtual reservoir. In addition, the display data calculation device 160 excludes the water flow rates between the plurality of distribution reservoirs belonging to the same group, and extracts only the water supply to distribution reservoirs in different groups. Finally, the display data calculation device 160 converts the operation schedule information D31 into the reduced operation schedule information D31r by the redefinition and extraction process, and registers this reduced operation schedule information D31r in the operation schedule database 131.

  As described above, the display data calculation device 160 that is the contracted operation schedule information generation device sets one virtual reservoir when there are a plurality of reservoirs belonging to the same group based on the grouping information D50, and sets the same group. A reduction calculation process for invalidating the water flow rate between a plurality of drainage basins belonging to the operation is executed, the operation schedule information D31 is converted into the reduced operation schedule information D31r, and the reduced operation schedule information D31r is registered in the operation schedule database 131. .

  Then, the display drawing creation apparatus 170 performs the system display process based on the reduced operation schedule information D31r instead of the operation schedule information D31, thereby reducing the drawing indicated by the reduced operation schedule information D31r. The operation schedule status of the water supply system can be displayed on the display device 180 by the contents.

  In addition, the display drawing creation apparatus 170 also performs the system | strain display process (detailed display) based on the driving schedule information D31 similarly to Embodiment 1-Embodiment 3, without using the reduction driving schedule information D31r. can do.

  FIG. 8 is an explanatory diagram illustrating a display result example by the water supply operation support information display system in the fourth embodiment. FIG. 8 shows the display contents obtained by contracting the water supply system shown in FIG.

  The drawing dividing device 150 identifies the distribution reservoir (icon) 16 as a high attention level configuration facility with a high degree of attention, and further, the upstream distribution reservoir (icon) 14, pumps (icons) 36 and 37, and the pump 37. The downstream reservoir (icon) 17 is specified as a non-grouping element.

  Then, the drawing dividing device 150 instructs the distribution reservoirs (icons) 11 to 13 and 15 and the pumps (icons) 31 to 35 and 38 shown in FIG. 4 other than the non-grouping elements as grouping elements set to the same group. Grouping information D50 is obtained.

  Next, based on the grouping information D50, the display data calculation device 160, from the operation schedule status of the water transmission system shown in FIG. 4 indicated by the operation schedule information D31, as shown in FIG. 15 is virtually set to one grouping reservoir icon 51 (virtual reservoir), the pump icons 31 to 35 and 38 are virtually set to two grouping pump icons 71 and 72, and the pipe line icons 21 to 25 and 28 are set to 2 Virtually set to the two pipeline icons 61 and 62. At this time, the size of the grouping reservoir icon 51 is changed in proportion to the total reservoir capacity of the previous stage to be virtually set, and the icon is also displayed large.

  Further, the display data calculation device 160 obtains the water storage amount of the grouping reservoir icon 51 and invalidates the water flow rate between the reservoirs (icons) 11 to 13 and 15 in the same group, while grouping pump icons 71 and 72. The reduction calculation process is performed to obtain the amount of water. Accordingly, the display drawing creating apparatus 170 instructs the size of the water storage amount icon V51 and the formation width of the pipe line icons 61 and 62 reflecting the above-described reduction calculation processing contents based on the reduced operation schedule information D31r. Drawing information D70 can be obtained.

  In this way, the display data calculation device 160 performs the above-described reduction calculation process on the operation schedule information D31 that indicates the operation schedule status in the water supply system as shown in FIG. 4, and the water supply system as shown in FIG. Is converted into reduced operation schedule information D31r that can be displayed, and the reduced operation schedule information D31r is stored in the operation schedule database 131.

  After the grouping processing by the drawing dividing device 150 and the reduction calculation processing by the display data calculation device 160, the display drawing creation device 170 performs the reduction operation schedule information D31r, the operation model information D32, the equipment model information D33, and the attention degree information D34. Based on the above, it is possible to display the operation schedule status of the water supply system after the contraction as shown in FIG. 8 on the display device 180 (contract drawing display).

  Note that in the grouping process of the drawing dividing apparatus 150, a threshold value or the like serving as a grouping determination criterion may be changed by an external input by a user, for example.

  The display drawing creation device 170 creates a display drawing by executing the grouping processing and the reduction computation processing again in real time when the user changes the criteria for grouping, and the drawing division device 150 and the display data computation device 160 perform the grouping processing and the reduction computation processing again in real time. Under the control of the device 170, the screen display content after the change of the grouping determination criterion by the user can be quickly displayed on the display device 180 on the display device 180. Therefore, the user who uses the system of the fourth embodiment can perform the contracted display and the detailed display at an arbitrary timing and in an arbitrary area.
