Description

  The present invention relates to a landslide maintenance management system and method for evaluating the risk of landslide and the influence on power transmission equipment.

  Conventionally, landslides have occurred due to heavy rains that occur like guerrillas. In recent years, such landslides tend to occur frequently in combination with abnormal weather, and as with other natural disasters such as typhoons and ice and snow, they are being recognized as threats to power transmission facilities.

  However, landslides that occur in the vicinity of power transmission facilities but do not have direct effects such as collapse or damage of steel towers have been annoying as a matter of concern for facility maintenance. In particular, how the landslide that will occur will affect the equipment in the future, how will the risk be assessed, whether there is a prior prediction technology, and is it possible to link prediction technology and maintenance technology? There was no literature explaining or instructing them, and there was no established technology with related know-how. In addition, there are the following prior arts as similar techniques in some specialized fields.

  Patent Document 1 discloses “a method and an apparatus for predicting ground displacement”, in which ground water collected is artificially pressurized and permeated to the soil collected from the slope ground to be monitored, It is described that the possibility of ground collapse is predicted by changes in characteristics.

  Further, Patent Document 2 discloses a “slope failure prediction and evacuation information transmission system to surrounding area”, which is a system for performing stability analysis on a slope to be monitored by a failure safety factor curved surface (arc slip method). A database that stores various ground characteristics, which are parameters other than the necessary rainfall data, and external information for specifying analysis operations. It is described that safety action information is issued.

Japanese Patent No. 4405853 JP 2006-252128 A

However, the above prior art has the following problems.
(1) In Patent Document 1, changes in electrical characteristics due to soil and groundwater collected from the ground required to be monitored are measured as the sole judgment material, and other parameters relating to landslide occurrence are not taken into consideration. In addition, since the neighborhood area that affects the steel tower covers a wide area, the type of soil to be collected and the groundwater level are not constant.Therefore, representative levels (average value or maximum value) are used as judgment materials when predicting slope failure. ) Must be used.
(2) In Patent Document 2, although the collapse safety factor curved surface (arc slip method) method has been established as a rational method in the stability analysis of the ground, other parameters relating to the occurrence of landslide are not considered. In addition, because it is intended to transmit safety behavior information to the residents in the vicinity, it is estimated that a considerable margin is expected in the evaluation of the analysis results, so it is not suitable for the judgment method used for monitoring the power transmission facilities, etc. .
(3) In any of Patent Documents 1 and 2, since the target to be monitored is an inclined ground to the last, depending on the target situation (for example, the stability of a steel tower, etc.) that the landslide affects, the same determination result may have an effect. Differences occur in the damage.

  The present invention has been made in view of the above problems, and a main object thereof is to accurately evaluate the risk of landslide and the influence on power transmission equipment.

In order to solve the above-mentioned problems, the present invention provides a landslide maintenance management system for determining countermeasures against landslides, and assigns, for each area, survey results that are results of investigating each survey item that causes landslides. Included in the acquired survey data based on the evaluation score data, means for preliminarily storing evaluation score data indicating evaluation scores to be obtained, means for acquiring survey data including the survey results for each area, and For each survey result, a means for assigning an evaluation score, a means for summing the assigned evaluation points for each area, and calculating a total evaluation score, and a total of the calculated evaluation scores for each area are included. Means for storing landslide management data; means for acquiring weather data of an area under the jurisdiction of the landslide maintenance management system; the acquired weather data; Based on the憶the landslide management data, means for identifying the area and Countermeasures to be measures, for each range of precipitation of the region, and the threshold of the evaluation point total area of evaluation points total more than the threshold value Means for storing precipitation countermeasure data including countermeasure contents against the above , and means for acquiring the weather data acquires precipitation in the area as the weather data, and determines the area to be countermeasured and the countermeasure contents. Based on the stored precipitation countermeasure data, a means for specifying identifies a threshold value of the evaluation point total and the content of the countermeasure from the acquired precipitation amount, and the evaluation point total is calculated from the stored landslide management data. the area is specified threshold or more, and specific to said Rukoto as an area to be measures the identified countermeasures.

  According to this configuration, the survey items relating to the landslide cover the landslide factors, and all the items are thoroughly investigated, thereby obtaining a survey result without any arbitrary judgment of the investigator. Next, since the evaluation score is determined from each survey result using the preset evaluation score data, an evaluation result without any arbitrary judgment by the evaluator can be obtained. According to the above, it is possible to accurately evaluate the landslide situation in the area and the influence on the equipment (for example, power transmission equipment) in the area.

And after acquiring the weather data of a jurisdiction area as disaster prevention information of a local government, the area and countermeasure content which should be countermeasured are specified with reference to landslide management data. According to this, the necessary landslide countermeasure can be implemented for the necessary area by the weather data of the disaster prevention information.
Furthermore, after acquiring the precipitation amount of the jurisdiction area as disaster prevention information of the local government, the landslide management data is referred to extract an area where the total evaluation point is equal to or greater than the threshold corresponding to the precipitation amount. And the countermeasure content according to the extracted area and precipitation is output. According to this, the areas where measures should be taken according to the precipitation target those that are estimated to be affected by the precipitation, so the necessary landslide countermeasures based on the precipitation in the disaster prevention information are necessary. Can be implemented for areas.

Further, in the landslide maintenance management system of the present invention, the evaluation points included in the evaluation point data may be set more as the survey result has a larger influence as a landslide factor.
According to this configuration, since many evaluation points are set for the dominant factors that have a large impact on the occurrence and scale of landslides, it is possible to accurately calculate the total evaluation points for the survey results for each area. it can. According to this, by accurately determining the evaluation items, it is possible to accurately grasp the landslide situation and identify an appropriate measure.

  The present invention includes a landslide maintenance management method. In addition, the problems disclosed by the present application and the solutions thereof will be clarified by the description of the mode for carrying out the invention and the drawings.

A CPU (Central Processing Unit) is stored in the predetermined memory. This is realized by executing the program. The storage unit 15 stores data from the processing unit 14 and reads the stored data, and is realized by a nonvolatile storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The The tower maintenance management system 1 may be a stand-alone device (PC (Personal Computer) or the like), or may be a device (server or the like) that can communicate with a plurality of terminals via a network.

<< Data structure >>
2A to 4 are diagrams showing a configuration of data stored in the storage unit 15 of the tower maintenance management system 1.

  2A, 2B and 2C show the configuration of the weighting data 15A. The weighting data 15A is evaluation point data for weighting the analysis result of the survey item relating to the landslide, and includes a record including the classification 15A1, the survey content 15A2, the determination item 15A3, the small classification 15A4, and the scoring 15A5. Category 15A1 is a classification of seven survey items, which covers the causes of landslides and includes the status of the tower itself. The investigation content 15A2 indicates the content to be specifically investigated, and 1 to 13 investigation contents 15A2 are set in one section 15A1. The determination item 15A3 is an item to be determined for the survey content 15A2. For example, four angle ranges are set as the determination item 15A3 for the “inclination angle of the slope near the site” of the survey content 15A2.

  The small classification 15A4 is a further subdivision of the determination item 15A3, and is set for some of the determination items 15A3. For example, the small classification 15A4 is divided into large, medium, and small with respect to the determination item 15A3 “is a slope having a wide gentle slope above”. Scoring 15A5 is a weighting evaluation point for determination item 15A3 or small classification 15A4. For example, in each angle range of the determination item 15A3, 1, 3, 5, and 7 are set as evaluation points, and as the inclination angle of the slope increases, more points 15A5 are set. This is based on the weighting concept that many evaluation points are set for factors that have a large impact on landslides (dominant factors).

  Note that “S” described in the score in FIG. 2C indicates that a landslide has already begun, so that some countermeasure is required immediately.

  FIG. 3 shows the configuration of the evaluation reference data 15B. The evaluation standard data 15B is data indicating an evaluation standard corresponding to the total evaluation score for each tower, and includes records including an evaluation rank 15B1, a quantitative evaluation standard 15B2, and a qualitative evaluation standard 15B3. Evaluation rank 15B1 shows the evaluation degree set in order to visualize the danger level of a landslide. The quantitative evaluation criterion 15B2 indicates a criterion for evaluating the risk level based on the total evaluation score of the analysis / evaluation vote. The qualitative evaluation standard 15B3 indicates the landslide situation and countermeasures according to the evaluation rank 15B1.

  FIG. 4 shows the configuration of the landslide management DB 15C. The landslide management DB 15C is a DB that manages data relating to landslides that occur in a mesh area centered on a steel tower. The track name is 15C1, the tower number is 15C2, the evaluation score is total 15C3, the evaluation rank is 15C4, the survey form is 15C5, and the analysis / evaluation is performed. Consists of records for each steel tower including the vote 15C6. The line name 15C1 indicates the name of a power transmission line installed on the steel tower, and a place name is generally used. The tower number 15C2 is a number unique to each tower that supports the transmission line, and a serial number is generally used. The total evaluation score 15C3 is the total evaluation score regarding the landslide in the mesh area including the steel tower. The evaluation rank 15C4 is an evaluation degree for the evaluation point total based on the evaluation reference data 15B, and any one of I to V is set. The survey form 15C5 shows survey data regarding the mesh area including the steel tower, and details thereof will be described later with reference to FIGS. 7A and 7B. The analysis / evaluation form 15C6 shows analysis / evaluation data regarding the mesh area including the steel tower, and details thereof will be described later with reference to FIGS. 8A and 8B.

≪System processing≫
FIG. 5 is a flowchart showing a procedure of investigation, analysis, and evaluation by the workers of the electric power company and the tower maintenance management system 1.
First, the worker grasps the local situation using the survey form (S501). Specifically, a survey on landslides is conducted for each tower, and a survey form is created that describes the method actually checked and the points of the grasped situation for each survey item.

7A and 7B are diagrams showing specific examples of survey forms. The survey form consists of 44 items in 7 categories, with a check method column for each category or survey item and a status column for each survey item. The categories include topographic features, slope features, slope springs, vegetation conditions, geological features, surrounding conditions, and tower conditions. Each category has 1 to 13 survey items, and the survey items are composed of the survey content and the reason for the survey. The check method and status are columns for entering the check method actually performed and the grasped status.
According to this, since the indirect factors of the landslide are covered in the survey form, it is possible to eliminate the arbitrary judgment of the investigator by investigating all items without omission.

  Next, the tower maintenance management system 1 acquires the contents entered in the survey form, and generates analysis / evaluation form data (S502). Specifically, the contents of the survey form input by the worker through the input unit 13 are acquired and stored in the storage unit 15, and weighting is considered in advance according to the status of each survey item using the weighting data 15A. Evaluation points are assigned, and the overall situation of each tower is evaluated by the total evaluation points.

8A and 8B are diagrams showing specific examples of analysis / evaluation votes. The analysis / evaluation vote is composed of records including classification, survey contents, judgment items, analysis results, small classifications, and evaluation points. For example, regarding the “inclination angle of the slope near the site” in the survey content, the analysis result states “the young side direction is 28 °” and “the young side landslide part is 32 °”. From the evaluation, 32 ° is applied. Referring to the weighting data 15A, 32 ° of the “tilt angle near the site” corresponds to “30 ° or more and less than 40 °”, so the score is 5, and 5 is set as the evaluation point of the analysis / evaluation vote. The Then, 81 is calculated and set as the total evaluation score by summing up each evaluation score.
According to this, since the evaluation score is determined from the analysis result or the small classification using the preset weighting data 15A, it is possible to eliminate the arbitrary judgment of the analyst / evaluator.

The tower maintenance management system 1 evaluates the risk of landslide from the data of the analysis / evaluation slip (S503). Specifically, based on the quantitative evaluation standard 15B2 of the evaluation standard data 15B, the evaluation rank 15B1 is identified from the total evaluation score of the analysis / evaluation vote for each tower, and the measures to be implemented in the future are determined based on the corresponding evaluation rank 15B1. The qualitative evaluation criteria 15B3 taking the directionality into account is specified and output.
According to this, it is possible to visualize the current steel tower and the surrounding risk by determining the qualitative evaluation standard from the total evaluation point using the preset evaluation standard data 15B.

  Furthermore, the steel tower maintenance management system 1 updates the landslide management DB 15C (S504). Specifically, the line name and tower number of the survey form in S501 (or the analysis / evaluation form in S502) are set in the storage unit 15 as the line name 15C1 and tower number 15C2. Next, the evaluation point total of the analysis / evaluation vote of S502 is set in the storage unit 15 as the evaluation point total 15C3. Then, the evaluation rank of S503 is set as the evaluation rank 15C4. Further, the contents of the survey form in S501 and the analysis / evaluation form in S502 are set as the survey form 15C5 and the analysis / evaluation form 15C6. In addition, the survey form and the analysis / evaluation form 15C6 may be configured so that the survey form and the analysis / evaluation form can be referred to by setting storage addresses of the already stored investigation form and analysis / evaluation form.

  FIG. 6 is a flowchart showing processing when the tower maintenance management system 1 receives disaster prevention information. As part of the utilization of the landslide management DB 15C, this process specifies and outputs measures to be implemented and the target steel tower in response to rainfall information received from the local government disaster prevention information system, for example. . The rainfall information includes the rainfall area, 48h precipitation and continuous precipitation. In addition, S607, S610, S613, and S617 show the work content of the worker.

  First, the tower maintenance management system 1 determines whether or not the rainfall area included in the received rainfall information is within the jurisdiction of the own system (S601). If it is not within the jurisdiction area (N in S601), the process is terminated. If within the jurisdiction (Y in S601), the 48h precipitation amount and the continuous precipitation amount included in the received rainfall information are checked, the 48h precipitation amount is 300 mm or more (S602), and the continuous precipitation amount is 150. If it is greater than or equal to millimeter (S603), the following processing according to the continuous precipitation is performed.

  If the continuous precipitation is 150 mm or more and less than 200 mm, the tower maintenance management system 1 extracts records (areas including towers) with an evaluation point total 15C3 of 50 or more from the landslide management DB 15C, and the corresponding track name 15C1. And a periodic confirmation necessity list including the tower number 15C2 is generated (S605). Then, for each track name and tower number in the periodic confirmation required list, a periodic confirmation list including a record slip is output (S606). The worker actually performs periodic confirmation of the tower and its surroundings using the outputted periodic confirmation list (S607). Then, the confirmation result is input to the tower maintenance management system 1.

  If the continuous rainfall is 200 mm or more and less than 250 mm, the tower maintenance management system 1 extracts records having an evaluation point total 15C3 of 70 or more from the landslide management DB 15C, and includes the corresponding line name 15C1 and tower number 15C2. A constant confirmation necessity list is generated (S608). Then, for each track name and pylon number in the constant confirmation required list, a constant confirmation list including a record slip is output (S609). The worker actually performs constant confirmation of the steel tower and its surroundings by using the outputted constant confirmation list (S610). Then, the confirmation result is input to the tower maintenance management system 1.

  If the continuous precipitation is 250 mm or more, the tower maintenance management system 1 extracts records having an evaluation point total 15C3 of 100 or more from the landslide management DB 15C, the tower including the corresponding line name 15C1 and tower number 15C2, and the foundation reinforcement An implementation list is generated (S611). Then, the steel tower and the basic reinforcement list including the record slip are output for each tower name and the steel tower number of the steel tower and the basic reinforcement implementation list (S612). The worker actually designs and implements the steel tower and the surrounding construction using the output steel tower and the foundation reinforcement list (S613). Thereafter, the processing of the tower maintenance management system 1 ends.

  The tower maintenance management system 1 acquires the result of the periodic confirmation in S607 or the constant confirmation in S610, and determines whether the result is normal (S614). If normal (Y in S614), the process is terminated. If it is not normal (N in S614), a regular confirmation list or a regular confirmation list including a recording slip describing the abnormal result is output (S615), and an abnormal recording temporary process for regular confirmation or regular confirmation is performed (S616). In addition to the temporary recording process, depending on the status change during monitoring, the tower and the foundation reinforcement list may be output in the same manner as in S612 to prompt the worker to design and implement the work. The worker refers to the regular confirmation list or the constant confirmation list output in S615 and conducts a detailed investigation after the fact (S617). Then, the tower maintenance management system 1 updates the landslide management DB 15C (S618). Here, instead of overwriting the existing data, the same tower is sequentially accumulated so that the situation changing in time series can be grasped, but the countermeasure list to be implemented is generated according to the latest data. Thereafter, the process ends.

  If the 48h precipitation is less than 300 mm (S602) or the continuous precipitation is less than 150 mm (S603), the tower maintenance management system 1 determines that no immediate countermeasure is required, and the precipitation is stored in the storage unit 15. Save and store (S619), and end the process.

  According to the above processing, anyone can take action according to the execution flow and output list of “periodic confirmation”, “always confirmation” and “steel tower, foundation reinforcement” quickly and easily at any time.

  In the above embodiment, in order to make each part in the tower maintenance management system 1 shown in FIG. 1 function, a program executed by the processing unit 14 is recorded on a computer-readable recording medium, and the recorded program It is assumed that the tower maintenance management system 1 according to the embodiment of the present invention is realized by causing a computer to read and execute. In this case, the program may be provided to the computer via a network such as the Internet, or a semiconductor chip or the like in which the program is written may be incorporated in the computer.

  According to the embodiment of the present invention described above, it is possible to accurately evaluate the risk of landslide and the influence on the power transmission equipment.

  Specifically, since the survey form covers all predisposing parameters correlated with landslides, highly accurate evaluation can be performed. Next, the survey, analysis, and evaluation including the status of the tower itself are conducted, and the results are accumulated in the landslide management DB 15C. Therefore, an evaluation that considers the tolerance and importance of the status of the tower can be performed. it can. And the rain data that is the cause of landslides are transmitted from the disaster prevention information system of the local government from time to time. By using the rain data, high-accuracy evaluation and labor saving of the tower maintenance management system 1 can be achieved. it can. Furthermore, anyone can take action according to the “monitoring level” and “steel tower / reinforcement level” implementation flow and output list quickly and easily when receiving disaster prevention information.

The present invention can be changed and improved without departing from the gist thereof, and equivalents thereof are also included in the present invention. For example, the following embodiments can be considered.

(1) You may lower the threshold value of the continuous precipitation in the processing flow of FIG. According to this, the safety of the power transmission equipment including the steel tower can be further ensured.
(2) As information received from the disaster prevention information system of the local government, it is conceivable to replace or combine information (meteorological data) such as winds and earthquakes that are causes of landslides other than rainfall. According to this, improvement of the tower maintenance management system 1 can be aimed at.
(3) Although the tower maintenance management system 1 has been described so as to identify the target area and the countermeasure content according to the continuous precipitation according to the processing flow of FIG. 6, other methods may be used. For example, a matrix that prescribes countermeasures according to weather evaluation points that are comprehensively evaluated from weather parameters such as precipitation, wind speed, and wind direction, and the total evaluation points related to landslides that are assigned to each area that includes a tower. Precipitation countermeasure data) is created and stored in advance. And when meteorological data is received from a disaster prevention information system, you may specify an object area and countermeasure content based on the above-mentioned matrix.
