  By the way, the length of the power transmission line is several tens of kilometers, and the result of picking up the construction site within a radius of 5.0 km from the power transmission line is a huge amount. It took a lot of man-hours and time to check. In addition, the forecasts of electric power companies and the estimates of cable operators are often very different, and considerable man-hours were used for the adjustment. Since a lot of man-hours and time are required for checking and the like, the construction contents may be approved without being able to perform sufficient verification.

  Correspondingly, a system capable of checking the estimate of a large amount of electromagnetic induction failure countermeasure construction and judging the validity of the construction is desired.

  The present invention has been made in view of the above-mentioned circumstances, and examines the new estimate contents while referring to the past construction database, and also confirms the validity of the estimate amount while referring to the standardized estimate database. The purpose is to provide a construction estimation support system, method, and program for evaluating the feasibility and assisting in making a contract with an optimal amount.

  In order to achieve the above object, a construction estimation support system according to the present invention divides a transmission line section into a plurality of sections, a construction content database for storing construction contents performed for each section, and necessary construction costs, Reads the section of the transmission line, the construction content, and the construction cost from the estimation information given as data in a predetermined format, and divides the section into a section that matches the construction content database, and the past information accumulated in the construction content database The construction cost of the designated section is calculated by comparing the construction section and construction contents of the construction section and the construction sections and construction contents disassembled by the estimate information analysis means for each construction section. And an estimated predicting means and an estimated comparing means for comparing the calculated estimated cost with the estimated cost and extracting the difference. To.

  According to the present invention, it is possible to determine the estimated content by referring to the past construction content in the predetermined section using the construction information received from the wire operator, further calculate the estimated prediction, and calculate the estimated prediction Therefore, only the difference from the received estimate information can be considered, and man-hours can be reduced.

  In the construction estimate support system, preferably, the estimated cost calculated by the estimated forecasting means is compared with the construction contents and construction costs for each section analyzed by the estimated information analyzing means, thereby estimating the construction cost. It is preferable to provide estimated validity judgment means for judging the validity of the forehead.

  According to the present invention, it is possible to determine whether the received construction information and the construction information including the construction section are valid or not. You can quickly give power companies the opportunity to hear detailed explanations.

  Further, the estimated validity judging means judges that the estimated construction cost read is valid if it is within a range that can be designated in advance from the past average value of the corresponding section and construction contents. It is also preferable to configure.

  According to the present invention, since it can be determined that the value is within a predetermined range from the past average value, a large amount of validity can be automatically determined using a computer, leading to a reduction in man-hours.

  Further, the estimated validity judgment means, when the estimated amount of the read construction cost is within a predetermined range from a value obtained by adding a past tendency to a past average price of the corresponding construction section and construction content. It is also preferable that the configuration is determined to be appropriate.

  According to the present invention, an index obtained by adding a recent tendency to past results is used as an index, and if it is within a predetermined range from the value, it can be determined to be appropriate. It is possible to use a value close to reality taking into account the tendency to do so. Therefore, it is possible to make a determination with higher accuracy, and the number of determination errors is reduced.

  More preferably, the estimated validity judgment means compares the read construction contents of the construction section with the past construction contents of the construction section of the transmission line, and gives a warning if the contents are the same. Configure to do.

  Further, the estimated validity determination means determines that the read construction content is not valid, or the read construction content is higher than the estimated construction content and the construction cost is higher. In the case of content, it is also preferable that a warning is given.

  According to the present invention, it is possible to point out to the construction content that the construction of the optical fiber is performed as the construction content, although there is no problem by performing the magnetic shielding as a countermeasure against the electromagnetic induction failure. No need to pay extra costs.

  Also, in the construction estimate support system, the construction contents and required construction costs for each section analyzed and created by the estimate information analysis means, and the construction contents and construction costs for each section predicted and created by the estimate prediction means are shown in the figure. It is also preferable that the apparatus is configured so as to include an estimate plotting means to be converted.

Therefore, the construction contents and construction newly estimated by the chart. It becomes possible to easily determine the appropriateness of the cost.

  Furthermore, in the construction estimate support system, it is preferable that the plurality of sections are configured to be changeable.

  According to the present invention, since it is possible to perform estimation prediction for each of various sections by changing a predetermined section, first, the estimation prediction is calculated in a large section, and is calculated by gradually dividing into smaller sections. Therefore, it is possible to determine the optimum section, and it is possible to perform estimation prediction with high accuracy of the estimated cost to be calculated.

  The construction estimation support system further includes a communication path database that stores a total number or an increase rate of the wireline business customers of the transmission lines that need to take measures against electromagnetic induction disturbance, and the estimation prediction means includes past construction contents. Regardless of the construction cost, if the total number of customers in the target construction section or the total number of customers taking into account the customer growth rate is greater than the predetermined number, optical fiber is selected as a measure against electromagnetic induction interference, and there is a construction cost. It may be configured to apportion with cable operators at a fixed rate.

  According to the present invention, it is possible to halve the cost because the optical fiber is selected and beneficial to each other depending on the scale and increase rate of the customers of the cable operators in the vicinity of the transmission line that need to take measures against electromagnetic induction disturbance. , Electric power companies can save money, and wire operators can also carry out the construction that may be done in the future after receiving a part of the construction cost from the electric power company, so it is possible to save money each other it can.

  The construction estimation support system further includes a communication path database that stores information on a communication path of a wire operator in the vicinity of a transmission line that needs to take countermeasures against electromagnetic induction failure. It is also preferable to determine a construction section where it is necessary to take a countermeasure against inductive failure, and calculate the construction cost of the determined construction section from the construction content database.

  According to the present invention, it is possible to predict the construction section and the construction contents from the past results and the communication route of the wire operator, and to automatically calculate the construction cost. This will make it possible to reduce the amount of work and work with the cable operator.

  The construction estimation support system further includes a standard estimation database for storing construction contents and costs required for construction for each section of the transmission line, and the estimate prediction means uses the standard estimation database to construct the construction contents for each construction section. It is also preferable to configure to calculate an approximate construction cost.

  According to the present invention, the estimate can be checked using a database that can be registered from the outside regardless of the past results. For example, the construction content and the construction cost for which credibility was obtained by the past check. Can be determined, stored as a standard estimate database, and compared. Also, by registering the construction contents and construction costs of other companies as a standard estimate database, it is possible to compare the contents of the estimate, so it is possible to compare various estimates and approach the probable estimate.

  FIG. 2 shows countermeasures against electromagnetic induction disturbance. As anti-magnetic measures, “None”, “Magnetic shield”, “Earth line to power pole”, “Optical fiber”, etc. indicating that there is no need to do anything are registered for each item number. This item number is registered in the database.

  FIG. 3 shows a data configuration example of the estimate DB 152. This estimate expands the cost for each section of the target transmission line based on the estimate information submitted by the cable operator, and a management number is assigned for each distance from the substation. A flag indicating whether the section is subject to construction or not, a construction number, an item number representing the construction content shown in FIG. 2, and an estimated cost are stored.

  This section can be corrected, for example, every 1 km or every 2 km. Or, if there are some circumstances, it may be an irregular distance (such as the distance between transmission poles). In Fig. 3, the area between 0 and 1 (Km) from the XX power transmission station is the construction object (1), the construction content is "magnetic shield" (item No. 1), and the construction cost is 1,000. It shows that it is necessary.

  FIG. 4 shows a data configuration example of the estimated route DB 155. This database extracts and stores sections that are determined by the wireline operator to perform construction from estimates, and assigns sections that are subject to construction in the estimate DB 152 according to the distance from the XX substation. The presence or absence of construction for the assigned control number is described in the “Construction” column. In the present embodiment, the construction contents and the estimated cost columns are deleted from the estimate DB 152, but the data configuration may be changed so as to be convenient for the subsequent processing.

  FIG. 5 shows a data configuration example of the construction content DB 151 that stores past magnetic-shielding measures. The construction content DB 151 determines a section based on the distance from the substation for each transmission line that is the target of all electromagnetic induction failure countermeasures, and assigns a management number.

In particular, it is not a necessary condition for carrying out the present invention that they are arranged in order of year.

  FIG. 6 shows a data configuration example in the estimated prediction DB 153 predicted based on past information. In the present embodiment, a configuration similar to the copy estimation DB 152 is easy to understand and easy to explain, and the same configuration is used. However, if there is no difference in the stored contents, the storage configuration may be different. In FIG. 6, the estimate prediction DB 153 is different from the estimate DB 152 in that an item of estimate basis is added. The points to be referred to are stored in the basis of this estimate, and are linked to the past construction contents, and are stored so that the basis of the estimated predicted value can be easily referred to.

  Moreover, although the item of estimated cost is the same as that of the estimate DB 152, the estimated amount predicted by the estimate predicting means 135 from the past construction information is stored in this column.

  7 and 8 show data configuration examples of the estimated comparison result DB 154. FIG. In the data configuration example of FIG. 7, the actual estimate and the construction work of the estimate prediction, the estimated amount, and the difference between the estimated amounts are stored for each management number of the target transmission line. This data is created by the estimate comparison unit 136. In addition to the items described in FIG. 7, in the data configuration example of FIG. 8, a column of results such as “OK” and “NG” of the construction content, a column of the result of the estimated amount, and the presence of “duplicate construction” And a “final result” column indicating final results represented by “OK” and “NG” are added. The above-described column is a column that is input by the estimate validity determination unit 137 with reference to the comparison result of the estimate.

FIG. 9 shows an outline of the flow of electromagnetic induction failure countermeasure construction for countermeasures against electromagnetic induction failures. First, the power company notifies the wireline company in advance of construction schedule information that causes an electromagnetic induction failure (F91). The cable operator who received the construction schedule information determines the influence range and the like, creates estimate information, and transmits it to the power company (F92). In this embodiment, the estimate information may be a printed document, but it is preferably a digitized document.
The power company that has received the estimate information identifies the section of the transmission line construction that the cable operator is going to construct from the estimate information, stores it in the estimated route DB 155 (F93), and divides the section into sections on the transmission line The estimate information is expanded (F94). The expansion of the estimate information is to identify the construction content and its cost for each section and store them in the corresponding area of the estimate DB 152.

  Next, the estimate predicting means 135 is an estimated route DB 155 extracted by the estimate information analyzing means 134 and storing the presence / absence of construction for each section, and a construction in which past construction contents and construction costs are stored for each section. The contents DB 151 is accessed (F95, F96), an estimate is predicted according to past results, and the result is stored in the estimate prediction DB 153 (F97).

  Next, the estimate comparison means 136 compares the estimated information developed for each section with the estimated estimate prediction information (F98, F99), extracts the difference, and stores it in the estimate comparison result DB 154 (F9A). . Then, the estimate validity determination means 137 determines the validity of the estimate based on the difference between the stored estimate information and the estimate prediction information. When the estimate is determined, the estimate is added to the construction content DB 151 (F9B). ).

  The construction estimation support system is configured as described above, and details of its operation will be described below.

[1. Information registration stage]
The administrator of the construction estimation support system checks the electromagnetic induction failure shown in FIG. 2 while checking the input device 15 such as a keyboard or mouse connected to the input unit 15 and a screen such as a display connected to the display unit 16. Enter the details of the countermeasure, information on the cable operator, etc., and information on how to divide the section of the transmission line. The inputted information on countermeasures against electromagnetic induction failure is stored in the storage unit 14 by the information registration unit 133.

  Similarly, although not shown in the figure, information such as the company name and telephone number of the wire operator and how to divide the section of the transmission line are also stored in the corresponding area of the storage unit 14 by the information registration unit 133.

[2. Estimate reception stage]
The operation after receiving the estimate information will be described with reference to the flowchart of FIG. The operation in FIG. 10 is performed by the estimate information analysis procedure 134.

  When the estimate information is received from the wire operator (S101), the estimate information analysis means 134 of the construction estimate support system 1 determines the transmission line from the received estimate contents, and determines the determined transmission line in advance, for example, transmission The transmission line is divided into sections using a method of dividing the sections based on the distance from the electric wires or the like, or a method of dividing the sections based on the distance between the power transmission columns (S102). In the construction content DB 151 according to the present embodiment shown in FIG. 5, sections are divided from the substation at regular intervals, for example, every 1 km. Next, it is determined whether the section corresponding to each section is a construction target (S103), and if it is a construction target, the fact that it is a construction target is described in the estimated route DB 155 (S104).

  In this flowchart, nothing is done if it is not a construction target, but it may be described that it is not a construction target.

  Next, the contents of the estimate information for each section are registered in the estimate DB 152 with the contents of the construction and the cost (S105). Next, it is determined whether or not the processing for all the sections has been completed (S106). If not, the next section is designated and the above operation is repeated (S107). When the processing of all sections of the target transmission line is finished, the operation is finished (yes route in S106).

[3. Estimated forecast stage]
After the target construction section of the target transmission line is found, a process for predicting the cost of the construction will be described with reference to the flowchart of FIG. The operation of FIG. 11 is an operation performed by the estimation prediction unit 135.

  First, the found construction target section is set as an estimation target section (S111). Next, the past construction contents of the section to be estimated are statistically taken in the same section of all the transmission lines (S112), and the construction frequency with the highest frequency is set as the construction contents for estimation prediction (S113). Referring to FIG. 5, the past construction contents at a certain position from the substation of each transmission line are shown. However, these construction contents and the construction contents of the same section of the next transmission line are also described. Take statistics as well.

  Next, with reference to the construction content DB 151 storing past magnetic-shielding measures, the average value of construction costs is calculated when the construction content is the same as the estimated construction details in the section including the same section of other transmission lines. (S114). The calculated average construction cost is stored in the corresponding column of the estimate prediction DB 153 as an estimate cost in the estimate prediction work contents (S115).

  Next, it is determined whether the processing for all the sections has been completed (S116). If there are still sections to be processed, the next section is designated (S117) and the above operation is repeated. If all sections have been processed, the process ends (yes route in S116). By the above operation, it is possible to determine, as an estimated forecast, the construction content that has been most frequently performed in the same section of all transmission lines in the past and the average cost of the construction.

[4. Estimate comparison stage]
Next, the operation of comparing the estimates and creating the estimate comparison result DB 154 will be described using the flowchart of FIG. 12 and the estimate comparison result DB 154 shown in FIG. This operation is performed by the estimation comparison unit 136.

  From the created estimate DB 152, the construction details of the designated section of the target transmission line are written in the corresponding column of the estimate comparison result DB 154 (S121). Similarly, in the estimated prediction, the construction content of the designated section of the target transmission line is written in the corresponding column of the estimated comparison result DB 154 from the estimated prediction DB 153 (S122). For the section to be constructed, the construction cost is written from the estimated DB 152 and the construction estimated cost from the estimated prediction DB 153 into the corresponding columns (S123, S124).

  Next, it is determined whether the processing of all sections of the target transmission line has been completed (S125). If not, the next section is designated and the above operation is repeated (S126). If completed, the operation is terminated (yes route of S125).

[5. Estimate validity judgment stage]
Next, the operation of determining the validity of the received estimated information and the estimated estimated prediction information using the estimated comparison result DB 154 will be described using the flowchart of FIG. 13 and the estimated comparison result DB 154 shown in FIG. This operation is performed by the estimated validity determination unit 137.

  First, it is determined whether the construction contents in the designated section are different between the estimate and the estimate prediction (S131). If they are the same, “OK” is written in the column of the result of construction in the estimate comparison result DB 154 shown in FIG. 8 (S132). If they are different, “NG” is written (S133). In the present embodiment, the character strings “OK” and “NG” are written, but “OK” can be represented by “1”, “NG” can be represented by “0”, and the like.

  If the construction contents are the same, the estimated construction costs are then compared (S134). In the case of the present embodiment, it is determined that the estimated cost is within an allowable range if the estimated cost does not exceed 10%, for example, from the estimated estimated cost amount. "OK" is written (S135). The permissible range can be determined separately, stored as data in the storage unit 14, and the above operation can be performed after acquiring the contents. When it is out of the allowable range, the corresponding column “NG” in the estimated comparison result DB 154 is written (S136).

Next, in order to determine the duplication of the construction, it is judged whether or not the same construction as the previous time has been performed (S137). If there is a duplication, “NG” is written in the “duplicate construction” column of the estimate comparison result DB 154 (S138), and if there is no duplication, “OK” is written (S139). Next, it is determined whether or not the processing for all the sections has been completed (S13A). If not, the next section is designated and the above processing is repeated (S13B). If the processing for all the sections has been completed, the operation ends (yes route of S13A).
With the above operation, the validity of the received estimate is determined by referring to the past results.

[6. Illustrate estimates and estimate forecasts]
FIG. 14 is a flowchart showing an operation for performing illustration using the estimate DB 152 which is the analyzed estimate contents and the estimate prediction DB 153 estimated by referring to the past construction contents for each section so that the operator can easily judge. It explains using. This operation is an operation performed by the quotation plotting means 138.

First, the construction content and construction cost of the designated section are acquired from the estimate DB 152 (S141). Similarly, the construction content and construction cost predicted for the designated section are acquired from the estimate prediction DB 153 (S142). Next, the estimated construction content and construction cost obtained and the estimated construction content and construction cost estimated are graphed as shown in FIG. 15 in the designated section (S143). Next, it is determined whether or not the processing for all sections has been completed (S144). If not, the next item is designated and the above operation is repeated (S145). If completed, the operation ends (yes route in S144).
The first embodiment of the present invention is configured and operates as described above.

  According to the present embodiment, it is possible to predict the estimate of the electromagnetic induction failure countermeasure construction work based on the past construction contents and construction costs classified for each section of the target transmission line, and receive the received new estimate information. By expanding each section above, it is possible to compare with the estimated forecast, and it is possible to output the part that does not match the estimated forecast, so there is an error in the estimate information or an estimate different from the forecast If it has been done, it is possible to point out, and it is possible to reduce the cost of construction costs that do not need to be paid.

  Next, a second embodiment will be described below. FIG. 16 shows a flowchart of the estimation prediction. In the second embodiment, the estimated contents of the construction contents and the construction cost are calculated in consideration of the tendency of the estimation.

  FIG. 16 is a flowchart showing a processing procedure performed by the estimate predicting means 135 according to this embodiment. In FIG. 16, step S163 and step S164 are different from FIG. 11 already described. By looking at the trend, we analyze the recent several to several tens of work contents and the construction cost required at that time, calculate the rate of change, and estimate the construction contents and the cost required for construction Predict.

For example, in the target construction section, the latest 10 cases are extracted, the contents of the construction and the required costs are acquired, the degree of change in the construction contents and the degree of change in the construction costs with the same construction contents are determined, and the construction contents Is determined (S163), and a construction estimated cost suitable for the construction content is calculated by calculating an average value of, for example, 10 recent construction costs (S164). In step S164, the construction cost may be generated by calculating the rate of change of the construction cost and adding or subtracting the difference from the average value.
The second embodiment of the present invention is configured and operates as described above.

  According to this embodiment, the construction content is determined in view of the past recent construction content, and the construction cost is calculated by calculating the past recent average amount or the past recent average amount plus the rate of change. It is possible to predict a more realistic estimate.

  Next, a third embodiment will be described below. FIG. 17 shows a data configuration example in the third embodiment of the construction content DB 151 in which past magnetic-shielding measures are stored. In the present embodiment, the content stored in the construction content DB 151 is different from the section divided by the distance from the substation, in addition to the distance from the transmission line at the location where the construction is performed in that section. .

  By including the distance from the transmission line as a parameter, the occurrence of electromagnetic induction failure depends on the distance from the transmission line, or the magnitude of the failure differs depending on the distance and the countermeasures are different. It becomes possible to manage electromagnetic induction failure countermeasures in more detail for each distance.

  In this case, in the flowchart of the estimate information analysis means 134 shown in FIG. 10, the construction content and construction cost are registered in the estimate DB 152 for each section and for each distance. Further, in the flowchart of the estimation predicting means 135 shown in FIG. 11, when statistics of the construction contents of the target section are obtained in step S112, statistics are further taken according to the distance from the transmission line. In step S114, the average construction cost is also calculated for each distance of the transmission line in the target section, and the average construction cost calculated in step S115 is further calculated from the transmission line for each target construction section. This is done for each distance.

  Further, in the flowchart of the estimate comparison unit 136 shown in FIG. 12, the construction content, the estimated cost, and the estimated predicted construction cost are written in the estimated comparison result DB 154 for each distance of the transmission line.

Depending on the distance from the target power transmission line of the target section, in step S137, whether the same construction as the previous work is being performed is also determined according to the distance from the power transmission line of the target section.

The illustration of the estimation shown in FIG. 14 is also illustrated for each target section according to the distance from the transmission line.
The third embodiment of the present invention is configured and operates as described above.

  According to the present embodiment, in addition to a section, the construction is managed by the distance from the transmission line in the section, so that more detailed construction contents and construction costs can be managed and a detailed estimate can be predicted. In particular, the portion where the electromagnetic induction disturbance depends on the distance from the transmission line can be covered in more detail. Therefore, it is possible to determine whether or not excessive measures are being taken in the estimation of the wire operator.

  Next, a fourth embodiment will be described below. FIG. 18 shows a configuration example of the communication path DB 156 that stores information on the communication path possessed by the wired operator related to the power transmission line, the number of customers of the wired operator in the section, and the growth rate thereof. This communication path DB 156 is stored in the storage unit 14 in the block diagram of the construction estimation support system 1 shown in FIG. 1, and is indicated by a broken line. In addition, this information is obtained by the power company by obtaining information from the cable company, or the power company registers the information created by the cable company in the database.

  In the present embodiment, the operation performed by the estimate prediction unit 135 will be described with reference to the flowchart of FIG. 19 is different from FIG. 11 only in steps S191 and S111, and the other steps are not changed, so only step S191 will be described.

  In step S111 in FIG. 11, the construction section is specified, and the construction section analyzed by the estimate information analysis unit 134 is extracted from the received estimate. Thereafter, the processing for each construction section is performed, but in FIG. 19, step S191 is performed. , The construction route is predicted using the communication path DB 156 for the power transmission line, and the operation for each subsequent construction zone is performed in the predicted construction zone.

  In the data configuration example of the communication path DB 156 shown in FIG. 18, the communication system DB 156 has distance information from the power transmission line for each section of the power transmission line, and the number of communication paths, the number of customers, and the customers within the distance range. Preserved growth rate. In step S191, the construction section is specified by the number of communication paths.

  According to this embodiment, by having the communication path DB 156, when power construction that requires countermeasures against electromagnetic induction trouble occurs, the construction is independently performed based on past construction information before receiving an estimate from the wire operator. It is possible to specify an interval and perform estimation prediction.

  Next, a fifth embodiment will be described below. In the fifth embodiment, when estimating the estimate, if the number of customers of the wireline operator in the target section or the growth rate of the number of customers exceeds a predetermined value, the optical fiber is selected as the construction. Is.

  The operation of the estimation predicting means 135 in this embodiment will be described using the flowchart of FIG. 11 differs from the operation of the estimate predicting means 135 shown in FIG. 11 in that the step S111 is changed to the step S201, and the steps S202 to S206 are further added. The construction contents are referred to the past construction information. And before deciding the estimate of the construction cost, the part that performs the following operations is added.

  First, the construction section identified by the estimation information analysis or the construction section predicted based on the communication path is set as the target section (S201). Next, the number of customers in the construction section and the customer growth rate are extracted (S202). When the number of customers is greater than or equal to a predetermined number (yes route in S203), the number of customers and the growth rate are calculated. If the value is equal to or greater than the predetermined value (yes route in S204), the optical fiber is selected as the construction (S205), the cost apportioned with the wire operator as the construction cost is written in the estimated prediction DB 153 (S206), and the next section The process proceeds to (S116). If the number of customers is less than the predetermined number (no route of S203) and the calculation result of the number of customers and the growth rate is smaller than the predetermined value (no route of S204), the process proceeds to step S112 and the previous explanation is made. Proceed with the actions you have performed.

  In addition, the communication path information is input to the communication path DB 156 by a wired operator, or after an electric power company obtains the information, or directly connected to a communication network such as the Internet. It is also possible for a wireline operator to log into the system and enter information.

  According to the present embodiment, when there is a need for electromagnetic induction failure countermeasures in an area where there are many customers or an area where the growth rate is high, considering the number of customers of the wireline operator and areas where the growth rate is high, As a countermeasure against inductive interference, an optical fiber line that can handle a large number of customers is selected as a countermeasure without being affected by electromagnetic inductive interference, and there is a mutual benefit, so that the construction cost will be split between the cable operator and the power company It can be performed.

  Next, a sixth embodiment will be described below. In the sixth embodiment, when estimating an estimate, an estimate is compared using a standard estimate database (DB) 157 in which standard construction contents and construction costs for each section are registered for each distance from the transmission line. Is. In this standard estimate DB 157, already credible construction contents and construction costs are registered in advance and compared with the registered standard estimate DB 157 when compared with the estimate.

  A data configuration example of the standard estimate DB 157 is shown in FIG. The standard estimate DB 157 is stored in the storage unit 14 in the block diagram of the construction estimate support system 1 shown in FIG. 1 and is indicated by a broken line. As can be seen in FIG. 21, each transmission line is divided into sections, and the construction contents and construction costs are registered for each section and for each distance from the transmission line. In the present embodiment, it is possible to check the estimate information obtained by the estimate information analysis unit 134 without using a past database. Moreover, after comparing with the construction content registered in the past construction content DB 151, the comparison with the standard estimate DB 157 may be performed.

  In the above embodiment, the configuration is used in the organization by LAN connection. However, the construction estimation support system according to the present invention is not only used in the organization but also opened to the wire operator, so that It is possible to instruct a business operator to create a new estimate after referring to a past estimate.
