A facility belongs to the CODE3 group, a facility from 1993 to 1997 belongs to the CODE4 group, a facility from 1998 to 2002 belongs to the CODE5 group, and is a facility after 2003 Defines the classification criteria to belong to the group of CODE6.

  FIG. 11C is a diagram showing the contents of the inspection result classification definition table included in each setting file 21 shown in FIG. The inspection result classification definition table is stored in the equipment specification table 12 according to the inspection result recorded in the inspection result field (column D) recorded in the equipment inspection table 13 shown in FIG. It is a table that defines the classification criteria for classifying the recorded equipment. Each equipment is classified into 8 groups from CODE "1" to "8", and the equipment belonging to each classified group is classified. The value of the inspection result and the color code of the icon color for displaying the equipment belonging to each group on the route map are defined.

  In the example of the illustrated table, the equipment whose inspection result is “Structure A” belongs to the CODE1 group, the equipment which is “Function A” belongs to the CODE2 group, and the equipment whose “Structure B” is the CODE3 group. The equipment that belongs to “Function B” belongs to the group of CODE4, the equipment that belongs to “Structure C” belongs to the group of CODE5, and the equipment that belongs to “Function C” belongs to the group of CODE6 and is “D”. The classification criteria are defined so that the equipment belongs to the CODE 7 group, and the equipment for which no value is input in the inspection result belongs to the CODE 8 group.

  (D) of FIG. 11 is a figure which shows the content of the arbitrary color classification classification definition table contained in each setting file 21 shown in FIG. The arbitrary color classification classification definition table is a table that defines classification criteria for classifying each equipment into the color codes recorded in the coloring field (T column) of the equipment specification table 12 shown in FIG.

  FIG. 12B is a diagram showing the contents of the icon list table included in each setting file 21 shown in FIG. An icon list table is a table which defines the shape of the icon which shows the position of the equipment displayed on a route map. Details will be described later in the description of the icon display process performed with reference to FIG.

  FIG. 13 is an overall flowchart for explaining the processing contents of the facility information management program 11. First, the facility information management program 11 accepts a selection input for selecting a route on which the facility to which the facility specification information and the facility inspection information are to be referenced in step S1. For this reason, the route selection screen shown in FIG. 14 is displayed on the display 4.

  On the route selection screen, route selection menus 101 to 103 for selecting a route to be displayed thereafter are displayed, and the operator uses these input means such as the mouse 9 and the keyboard 5 to display on these menus. A route is selected by selecting one of the routes that has been selected.

In step S2, a route map of the selected route is displayed on the display 4. FIG. 15 is a diagram showing a route map display screen including the route map displayed in step S2, and FIG. 16 is a flowchart of a map display routine S2 for displaying the route map.
When calling up the map display routine S2, the latitude and longitude of the upper left point of the map to be displayed and the scale are designated, and the upper left point of the display area 114 on the display 4 and the height and width of the display area are designated. Here, for each route, the latitude and longitude and the scale of the upper left point of each route map are determined in advance, and the route selected in step S1 is determined from the latitude and longitude and the scale of each route. Specify the latitude / longitude and scale.

In the map display routine S2, first, in step S701, the range of absolute latitude and longitude coordinates of the map to be displayed is determined.
For example, in step S701, based on the scale of the map to be displayed and the height and width of the display area on the display 4, the width of the absolute latitude coordinate and the width of the absolute longitude coordinate of the range of the map to be displayed are calculated. By calculating the latitude and longitude coordinates of the lower right point of the map to be displayed from the width of each of these absolute latitude and longitude coordinates and the latitude and longitude of the upper left point of the map to be displayed, Determine the range of absolute latitude and longitude coordinates.

In step S <b> 702, map drawing data within the range determined in step S <b> 701 is read from the map data 23.
In step S703, the latitude / longitude coordinate value of the drawing data read in step S702 is converted into the coordinate value of the device coordinate system on the display 4.
In step S704, the drawing data read in step S702 is drawn on the display 4 using the coordinate values converted in step S703.

When the data capture button 111 is pressed on the route map display screen shown in FIG. 15, the process proceeds to the data capture routine S10 due to the conditional branch in step S3 of the flowchart shown in FIG.
FIG. 17 is a flowchart of the data fetch routine S10. In the data fetching routine S10, the equipment specification information recorded in the equipment specification data 31 created from the equipment ledger is taken into the equipment specification table 12 or recorded in the equipment inspection data 32 created from the inspection ledger. The facility inspection information of each facility is taken into the facility inspection table 13.

First, in step S101, an instruction for a folder in the hard disk 6 in which files of equipment specification data 31 and equipment inspection data 32 exist is received from an operator.
In step S102, an instruction is received from the operator as to which of the equipment specification data 31 and the equipment inspection data 32 is the data to be captured.
In step S103, when the instruction input received in step S102 indicates that the equipment inspection data 32 is present, the process proceeds to step S104, the equipment inspection data 32 is taken into the equipment inspection table 13, and the processing is terminated.

In step S103, when the instruction input received in step S102 indicates that the equipment specification data 31 is present, the process proceeds to step S105, and each record of the equipment specification data 31 is taken into the equipment specification table 12.
Each record of the facility specification data 31 does not include the facility code field, the government building / toll gate type field, and the government building / toll gate code field (G to I columns in FIG. 3) of the facility specification table 12. Therefore, first, in step S106, the equipment code of the record newly taken into the equipment specification table 12 is determined and recorded in the equipment code field (G column).

The operator can specify information related to the facility code by, for example, the following method. First, the facility specification data 31 is created using commercially available spreadsheet software that creates spreadsheet format table data. At this time, each table is divided for each type of equipment and input to separate sheets. And the equipment name of the kind of equipment recorded on each sheet is recorded in advance in the sheet name recording area of each sheet.
When the equipment specification data 31 is fetched in step S105, the equipment name recorded in the recording area of the sheet name of the sheet being fetched is read, and this equipment master table shown in FIG. The equipment code defined for the name is acquired from the equipment code field (column A) and recorded in the equipment code field (column G) of the new record added to the equipment specification table 12.

  More simply, in step S105, the facility specification data 31 may be captured for each facility type, and the facility name of the facility type of the facility specification data 31 to be captured may be input to the operator. And the equipment code defined in the equipment master table shown in FIG. 5C for the inputted equipment name is obtained from the equipment code field (column A), and the equipment of the new record added to the equipment specification table 12 is obtained. It may be recorded in the code field (G column).

In step S107, it is determined whether each facility that has captured the facility specification data 31 in step S105 should determine its installation position based on the distance indicator, or should determine its installation position based on the position of the reference point. Determine for each equipment.
For this purpose, the value of the equipment classification field defined in the equipment master table is referred to the equipment code recorded in step S106. If this value is “1”, the equipment is based on the distance indicator. The process proceeds to step S110 by determining that the installation position should be determined. If “2”, the facility determines that the installation position should be determined by the position of the reference point, and the process is performed. Proceed to S120.

In step S110, the latitude and longitude of this equipment is determined and recorded in the facility position table 16 for the equipment whose equipment classification is “1” in step S107.
In the fields of conventional road management and railway management, distance information is used in most cases as position information for specifying the position of each facility arranged along a route. For example, also in the equipment specification data shown in FIG. 4, a distance indicator field (I column) is provided in order to specify the position of each equipment, and the distance is recorded.
However, since the distance information is one-dimensional information indicating the distance from the starting point of the route, the distance information alone cannot determine the two-dimensional coordinates on the route map which is a two-dimensional drawing. Therefore, in order for the facility information management program 11 to display the icon of the position of each facility on the route map, it is necessary to convert the distance information, which is one-dimensional information, into two-dimensional coordinates on the route map.

  Therefore, in step S110, the distance of the equipment recorded in the distance marker field (L column in FIG. 3) in the equipment specification table 12 for recording the equipment, and the distances of the nearest distance markers sandwiching the equipment. The latitude / longitude of the arrangement position of the equipment is calculated by interpolating the latitude / longitude information of these distance markers.

FIG. 18 is a diagram showing a flowchart of a subroutine S110 for determining the arrangement position of the equipment from the position information of the distance marker recorded in the distance marker table 14, and FIG. 19 is an explanatory diagram of the determination method.
In step S111, the same route code and direction code as the route code and direction code (column C and row D in FIG. 3) recorded in the record in the equipment specification table 12 for recording the equipment C shown in FIG. The nearest two distance markers that have the distance Kc of the equipment C and are located are searched from the distance marker table 14.
Two distance markers A and B extracted by this search are shown in FIG. Here, it is assumed that the distance measure and (latitude, longitude) of the distance marker A are Ka and (Ya, Xa), respectively, and the distance measure and (latitude, longitude) of the distance marker B are respectively Kb and (Yb, Xb).

In step S112, whether the equipment C is at the same position as one of these distance marks A and B or between the distance marks A and B is determined between the equipment C and the respective distance marks A and B. Judgment is made according to the difference in distance. When the equipment C is at the same position as either of the distance markers A and B, the latitude and longitude of one of the distance markers A and B having the same distance as the facility C is calculated in step S113. It is determined as the latitude and longitude of the facility C.
If the facility C is in the middle between these distance markers A and B, the distance is calculated by proportional distribution according to the distance from the facility C to the two adjacent distance markers A and B in step S114. The latitude and longitude of the equipment is calculated and determined from the latitude and longitude of the marks A and B.

For example, in the example shown in FIG. 19, the distance between the distance markers A and B can be obtained as (Kb−Ka), and the distance from the facility C to the distance marker A can be obtained as (Kc−Ka). The latitude Yc and the longitude Xc of the facility C can be calculated by the following equations, respectively.
Xc = Xb + (Kb−Ka) / (Kc−Ka) × (Xb−Xa)
Yc = Yb + (Kb−Ka) / (Kc−Ka) × (Yb−Ya)

  Returning to FIG. 17, in step S <b> 108, a new record having the registration number of the facility and the latitude / longitude determined in step S <b> 110 is added to the facility location table 16. Here, the same latitude information is recorded in the center latitude 1 field and the center latitude 2 field (columns B and D in FIG. 10) of the added record, and the center longitude 1 field and the center longitude 2 field (column C in FIG. 10). And E column) may record the same longitude information.

On the other hand, in step S120, the government office / tollgate master table is searched for the government office / tollgate code of the reference point having the same name as the location name of the equipment (column F in FIG. 3) recorded in the equipment specification table 12. The latitude / longitude information of the reference point having the government building / tollgate code is searched from the reference point table 15 and determined as the latitude / longitude of the arrangement position of the equipment.
FIG. 20 is a flowchart of a subroutine S120 for determining the facility arrangement position from the position information of the reference point recorded in the reference point table 15.

  In step S121, the government building / toll gate code and the government building defined in the government building / toll gate master table for the location name recorded in the location name field (F column in FIG. 3) of the facility record in the facility specification table 12 are displayed. / Get toll gate type. The acquired government building / toll gate code and government building / toll gate type are recorded in the government building / toll gate code (I column) and the government building / toll gate classification code (H column) in the equipment specification table 12. .

  In step S122, it is determined whether or not the facility is arranged at the toll gate based on the government building / toll gate type acquired in step S121. Here, if the value of the government building / toll gate type acquired in step S121 is “2”, it is determined that the facility is located at the toll gate, and the process proceeds to step S123. If there is, the process proceeds to step S124.

In step S123, it has the same government building / toll gate code as the government building / toll gate code acquired in step S121, and has the same lane number as the lane number (column E in FIG. 3) of the toll gate where the equipment is located. The reference point is searched from the reference point table 15, and the latitude / longitude of the found reference point is determined as the latitude / longitude of the facility.
In step S124, a reference point having the same government building / toll gate code as the government building / toll gate code acquired in step S121 is searched from the reference point table 15, and the latitude / longitude of the found reference point is determined as the latitude / longitude of the facility.
Returning to FIG. 17, in step S108, a new record having the registration number of the facility and the latitude and longitude determined in step S120 is added to the facility position table 16.

Returning to FIG. 15, when the display facility selection button 112 is pressed on the route map display screen, the process proceeds to the display facility selection routine S <b> 20 due to the conditional branch in step S <b> 3 of the flowchart shown in FIG. 13.

In the display facility selection window, a facility item input column 121, a facility type input column 122, an add button 123, a delete button 124, a selected facility list column 125, and a scroll button 126 are provided.

In step S201, the facility item (column B in FIG. 5C) recorded to indicate the classification of each facility code in the facility master table is selected. The operator inputs the facility item to which the facility code of the facility to be displayed as an icon belongs in the facility item input field 121.
In step S202, the operator selects an equipment name corresponding to the equipment code of the equipment to be displayed as an icon in the equipment type input field 122. The equipment name is added to the selected equipment list field 125 by pressing the add button 123 while the equipment name is entered in the equipment type input field 122.
By displaying the equipment name in the selected equipment list column 125, the equipment code corresponding to this equipment name is selected as the type of equipment to be displayed as an icon, and the equipment having the selected equipment code is displayed as an icon. The equipment to be selected.

In step S203, the operator operates the scroll button 126 in a state where any of the equipment names displayed in the selected equipment list field 125 is selected, thereby changing the display order of the equipment names in the selected equipment list field 125. .
In step S204, an icon shape is determined for each equipment name displayed in the equipment list field 125. The computer 1 refers to the icon list table ((B) of FIG. 12) in the setting file 21 shown in FIG. 2, and in the selected equipment list column 125, what number each equipment name is displayed in the list. Accordingly, the icon shape for each equipment type corresponding to each equipment name is determined from the icon type column of the icon list table.

In step S205, by selecting a record having an equipment code corresponding to the equipment name displayed in the selected equipment list field 125 from the equipment specification table 12, each equipment to be displayed as an icon is selected.
In step S206, the latitude and longitude of the facility of the record selected in step S205 is acquired from the facility position table 16. That is, a record having the same registration number as the equipment registration number of the record selected in step S205 is selected from the facility position table 16, and the latitude and longitude recorded in the selected record are acquired. At this time, when the scale of the route map currently displayed in the current route map display area 114 is as large as 1/3000 to 1/800, the latitude from the central latitude 1 field (column B) and the central longitude 1 field (column C) If the longitude is acquired and is smaller than 1/6250, the latitude / longitude is acquired from the center latitude 2 field (D column) and the center longitude 2 field (E column).

In step S207, for each piece of equipment selected in step S205, an icon of the shape selected in step S204 is displayed at the position of the latitude and longitude acquired in step S206 on the route map displayed in the route map display area 114. To do.
FIG. 23 shows a flowchart of the icon display routine S207. When calling the icon display routine S207, the latitude / longitude of the position where the icon is displayed, the icon shape, and the icon color are designated. Here, a fixed value (for example, white) is designated as the color of the icon, the latitude and longitude of the display position of the icon designates the latitude and longitude of the equipment to be displayed acquired from the facility position table 16 in step S206, and the shape of the icon is step. Designate the shape determined in S204.

In step S711, the latitude / longitude information of the icon designated by the caller is converted to the coordinate value of the device coordinate system on the display 4. Since the map display routine S2 shown in FIG. 16 has already been executed in order to display the route map in the route map display area 114, the latitude and longitude and the scale of the upper left point of the route map being displayed, and the display area on the display 4 are displayed. The upper left point 114 and the height and width of the display area are already known. Accordingly, the computer 1 can convert the latitude / longitude information of the icon into the coordinate value of the device coordinate system on the display 4 in the same manner as in step S703 of the map display routine S2 shown in FIG.
In step S712, the icon of the designated color and shape is displayed at the coordinate position determined in step S711. FIG. 24 is a diagram illustrating a state in which the icon 131 is displayed on the route map displayed in the route map display area 114.

  Returning to FIG. 15, when any location in the route map display area 114 is indicated (clicked) with the mouse 9 on the route map display screen, the process is displayed as the specification information by the conditional branch in step S <b> 3 in the flowchart shown in FIG. Control goes to routine S30. In the specification information display routine S30, when there is an icon at the clicked position in the route map, the facility specification information recorded in the equipment specification table 12 and the equipment inspection table 13 for the equipment indicated by the designated icon, and Equipment inspection information is displayed on the display 4.

FIG. 25 is a flowchart of a specification information display routine. In step S301, the latitude and longitude of the clicked position in the route map are acquired. 27 is a flowchart of the latitude / longitude acquisition routine S301 shown in FIG.
In step S721, the coordinate value of the device coordinate system on the display 4 where the mouse 9 is clicked is acquired from the operating system 10 that operates the computer 1.
In step S722, the latitude / longitude and scale of the upper left point of the route map used when the route map is displayed in the route map display area 114, and the height and width values of the upper left point and display area of the display area 114 are used. And the coordinate value of the apparatus coordinate system acquired by step S721 is converted into the latitude longitude.

Returning to FIG. 25, in step S <b> 302, the facility whose icon is displayed in the route map display area 114 is selected from the facility specification table 12. That is, a record having the equipment code selected by the display facility selection routine S20 is selected from the equipment specification table 12.
In step S303, the latitude / longitude of the equipment recorded in the record selected in step S302 is acquired. That is, a record having the same registration number as the registration number (column A) of the record selected in step S302 is selected from the facility position table 16, and the latitude and longitude recorded in the selected record are acquired. At this time, when a route map of a large scale (1/320 to 1/800) is displayed in the current route map display area 114, the latitude from the central latitude 1 field (column B) and the central longitude 1 field (column C) When longitude is acquired and a route map of large scale (1/6250) is displayed, latitude and longitude are acquired from the center latitude 2 field (D column) and the center longitude 2 field (E column).

In step S304, among the records acquired in step S302, the record in which the latitude and longitude acquired in step S303 for each of these records is within a predetermined distance from the latitude and longitude acquired in step S301 is selected.
In step S305, it is selected whether there are a plurality of records selected in step S304. If the number of records selected in step S304 is single, the number of icons present at the clicked position on the route map, that is, the number of facilities is only one. The equipment specification information recorded in the record and the equipment inspection information recorded in the equipment inspection table 13 for the equipment recorded in the record are displayed on the display 4 (step S305). FIG. 27 is a diagram showing a facility information display window for displaying the equipment specification information and the equipment inspection information.

As shown in the figure, in the facility information display window, a specification information display column 141 for displaying the facility specification information recorded in the record of the facility specification table 12 selected in step S304, and the same registration number as this record are displayed. It has an inspection information display column 142 for displaying the equipment inspection information recorded in the record of the equipment inspection table 13 it has.
The facility information display window also includes a photo list 143 for displaying a list of photo files recorded in the hard disk 6 for the facilities recorded in the record of the facility specification table 12 selected in step S304, and this facility. A drawing list 145 for displaying a list of drawing files recorded in the hard disk 6, a document file 146 recorded in the hard disk 6 for this equipment, and the first photo file displayed in the photo list 142. It has a photo display field 144 for displaying the contents of the file displayed at the top.

  Returning to FIG. 25, if it is determined in step S305 that there are a plurality of records selected in step S304, it means that there are a plurality of icons, that is, a plurality of facilities, at the positions clicked on the route map. In this case, the process proceeds to equipment selection acceptance processing step S307. In step S307, a selection instruction for selecting any of the plurality of records selected in step S304, which is input by the operator, is received. FIG. 28 is an equipment selection window for selecting one of a plurality of records in the equipment selection acceptance processing step S307.

  In the same point equipment display column 151 of the equipment selection window, the equipment name corresponding to each equipment code recorded in the plurality of records selected in step S304 and the equipment serial number (column B in FIG. 3) are displayed. The operator selects any one of the plurality of records selected in step S304 by selecting one of the displayed facility names.

In step S308, the facility specification information recorded in the record selected in step S307 and the facility inspection information recorded in the facility inspection table 13 for the facility recorded in this record are displayed in the facility information shown in FIG. Display in window.
In actual sites where actual facilities are arranged, a plurality of facilities are often arranged within the same support or instrument box. In particular, as in this embodiment, a plurality of different types of equipment, for example, pole lighting, variable information board, street information board, CCTV, VICS, and ETC roadside device installation position icons are displayed simultaneously. Are often arranged at the same position.
Therefore, when there are a plurality of facilities at the clicked position on the route map, a facility information display window for displaying a list of the plurality of facilities is displayed on the display 4, and the list of the plurality of facilities is displayed. The operator's selection operation is supported by executing the facility selection receiving process (S307) for selecting the facility to display facility specification information and facility inspection information.

Returning to FIG. 15, when the search display function button 115 is pressed on the route map display screen, the process proceeds to the color coding / search display routine S40 by the conditional branching in step S3 of the flowchart shown in FIG.
In the color classification / search display routine S40, search display processing for restricting icon display is executed by further selecting and narrowing down the facilities selected by the display facility selection routine S20 described above according to a predetermined selection criterion.
In the color classification / search display routine S40, the facilities selected by the display facility selection routine S20 described above and having icons displayed on the route map are classified into a plurality of groups according to a predetermined classification standard, and are displayed on the route map. A color-coded display process for color-coding the displayed equipment position icon for each group is executed.
The search display process and the color-coded display process can be executed by selecting either one or both of them at the same time. When the search display process and the color-coded display process are executed simultaneously, the icon of the equipment selected by the search display process is displayed. Only the colors are displayed.

FIG. 29 is a flowchart of the color coding / search display routine S40. When the process moves to the color classification / search display routine S40, a display type selection button is displayed on the display 4. FIG. 30 shows a state in which a display type selection button including a color classification display function button 161 and an arbitrary color classification display button 162 is displayed.
In step S401, the operator receives an instruction input for pressing one of the color-coded display function button 161 and the optional color-coded display button 162. When the color classification display function button 161 is pressed in step S401, the process proceeds to step S403 due to the conditional branch in step S402, and the display 4 displays the type of selection criterion used for the search display process and the color classification display process. A color classification / search type designation window for designating the type of classification standard to be used is displayed. FIG. 31 shows a color classification / search type designation window.

In step S403, the operator operates the search type designation menu 163 of the color classification / search type designation window to designate the type of selection criterion used for the search display process, and operates the color classification display type menu 164. Specifies the type of classification standard used for color-coded display processing.
Here, as the predetermined reference value used for selecting the equipment to be displayed as an icon in the search display process, the number of years elapsed since the installation of each equipment, the installation year, or the inspection result (inspection rank) is adopted. .

In the color-coded display process, the elapsed year, the installation year, or the inspection rank is similarly adopted as a predetermined reference value used for color-coding the equipment to be displayed with icons.
In the color-coded display processing, for each group classified, a range of reference values to be satisfied by the equipment belonging to each group and an icon color of each group are determined in advance, and each group depends on which range the reference value of each equipment belongs to. The equipment is classified into groups, and icons of the equipment classified into the groups are displayed in the icon colors of the groups.
The range of reference values and icon colors for each group are the elapsed year category definition table, installation year category definition table, and inspection year category definition described with reference to FIGS. 11 (A) to 11 (C), respectively. Defined by table.

  For example, the elapsed year classification definition table includes the number of years from the date recorded in the installation date field (column Q) of the equipment specification table 12 shown in FIG. When the number of elapsed years) is adopted as the reference value, equipment with an elapsed age of -6 years or less is classified into CODE1 groups, and equipment with -5 years to -1 years is classified into CODE2 groups. Then, classify equipment from 0 years to 4 years into CODE3 groups, classify equipment from 5 years to 9 years into CODE4 groups, and classify equipment from 10 years to 15 years into CODE5 groups. It defines that equipment over 15 years is classified into CODE6 groups.

  In addition, when the installation year classification definition table adopts the installation year (that is, the year recorded in the installation year field (column R) of the equipment specification table 12 for each facility) as the reference value, the installation year is 1982. The former facilities are classified into CODE1 groups, the facilities between 1983 and 1987 are classified into CODE2 groups, and the facilities between 1988 and 1992 are classified into CODE3 groups. The equipment from 1993 to 1997 is classified into the CODE4 group, the equipment from 1998 to 2002 is classified into the CODE5 group, and the equipment after 2003 is grouped into the CODE6 group. The classification is defined as

  In addition, when the inspection result (that is, the value of the inspection result field (column D) recorded in the equipment inspection table 13 shown in FIG. 7 for each facility) is adopted as the reference value, the inspection result classification definition table indicates that the inspection result is “ The equipment of “Structure A” is classified into the group of CODE1, the equipment of “Function A” is classified into the group of CODE2, the equipment of “Structure B” is classified into the group of CODE3, and “Function B” is classified. ”Is classified into CODE4 groups,‘ structure C ’is classified into CODE5 groups,‘ function C ’is classified into CODE6 groups, and‘ D ’. It is defined that the equipment is classified into groups of CODE7, and the equipment for which no value is input in the inspection result is classified into the group of CODE8.

In step S403, one of these reference values (elapsed years, installation year, or inspection rank) is specified in the search type designation menu 163 and the color-coded display type menu 164 as the types of selection criteria and classification criteria, respectively. Here, the following description will be made on the assumption that the installation year is designated as the reference value of the selection criterion and the inspection rank is designated as the reference value of the classification criterion.
In step S404, the color coding / search condition designation window shown in FIG. The operator designates a selection condition that is a condition to be satisfied by the facility displayed by the icon by operating the narrowing-down condition designation menu 165. Here, since the installation year of each facility is designated as the reference value of the selection criterion, the range of the installation year of the facility displayed as an icon is selected as a selection condition.
In addition, the operator presses the color designation button 166 and operates a color selection menu (not shown) displayed to select the icon color of the equipment belonging to each classified group.

In step S405, the records to be displayed as icons are narrowed down according to the selection conditions specified in step S404. FIG. 33 is a flowchart of the display record narrowing routine S405.
In step S421, a record of equipment of the type selected by the aforementioned display facility selection routine S20 is selected from the equipment specification table 12.
In step S422, among the records selected in step S421, a record of equipment that satisfies the selection condition specified in step S404 is selected.

Returning to FIG. 29, in step S406, it is shown in (A) to (C) of FIG. 11 in accordance with which elapsed year, installation year, or inspection year is selected as the reference value of the classification condition in step S403 of FIG. From the three category definition tables, an elapsed year category definition table, an installation year category definition table, and an inspection year category definition table are selected.
Next, according to the reference values of the plurality of records selected in step S405, the records are classified into any of the groups defined here according to the classification definition table. Then, the color defined in the classification definition table for each group is determined as the icon color of the record belonging to each group.

In step S407, when the records of the plurality of different facilities provided at the same position are included in the plurality of records of the facility specification table 12 selected at step S405, among the plurality of facilities at the same position. The same point priority display process is executed for determining which equipment icon should be displayed according to the priority order based on the order of the groups classified in step S407.
The advantage of performing the same spot priority display process will be described. By performing color-coded display processing, it is possible to change the display color of each facility icon according to the age, installation year, and inspection result of each facility, and to increase or decrease the level of appeal to the visual sense of the operator who sees these icons. it can. Usually, it is conceivable to arrange a conspicuous icon color such as red on equipment that needs attention from the operator, such as old equipment or equipment that has a high priority of inspection or repair such as poor inspection results.

However, a plurality of facilities are often arranged at the same location as described above. This tendency is particularly strong when icons of a plurality of types of equipment are displayed simultaneously as in this embodiment. For this reason, when icons of a plurality of facilities are displayed at the same point, depending on the icon drawing order, other icons may be displayed on the icon to be made conspicuous (an icon with a conspicuous color). There may be a problem that the icon of the facility that needs to call attention is hidden.
For this reason, when icons of a plurality of facilities are displayed at the same point, any one of the icons of the plurality of facilities is displayed according to the priority order based on the order of the groups classified by the color-coded display processing by the same point priority display processing. By selecting the above, the above inconvenience is solved.

FIG. 34 shows a flowchart of the same spot priority display processing routine S407.
In step S431, the longitude and latitude of each facility of the plurality of records in the facility specification table 12 selected in step S405 in this example are acquired from the facility position table 16. That is, for each of the plurality of records selected in step S405, the longitude and latitude recorded in the record in the facility position table having the same registration number as the record is acquired.
In step S432, the value of the iteration variable “i” used in the following iteration steps S433 to S437 is initialized.

In step S433, display permission determination regarding whether or not to display an icon for the i-th record among the plurality of records selected in step S405 is executed in advance for the first to (i-1) -th records. In step S435, it is determined whether or not it has already been performed. If the display permission / inhibition determination for the i-th record has already been made, steps S434 and S435 are skipped, and the process proceeds to S436.
If the display availability determination for the i-th record has not been made yet, the latitude and longitude of the equipment of each record acquired in step S431 and the latitude and longitude of the equipment of the i-th record are respectively obtained in step S434. By comparing, the record of the facility at the same point as the facility of the i-th record is selected from the plurality of records selected in step S405.

In step S435, the order of the groups classified in step S406 of FIG. 29 in the i-th record and the record selected in step S434 is compared. Here, as the order of each group, the value in the CODE column defined in each classification definition table shown in (A) to (C) of FIG. 11 may be used.
Then, the icon display is permitted only for the record with the highest priority in the order of the belonging group among the i-th record and the record selected in step S434, and the icon display is prohibited for the other records.
When the priority order is determined based on the value in the CODE column, whether the priority order is determined in ascending order or descending order of the value in the CODE field is determined according to the setting of the same point priority display setting table shown in FIG.

  In step S436, the value of the repetition variable “i” is increased by 1. In step S437, it is determined whether or not the i-th record, that is, the next record is present. If there is no next record, the process ends. If there is still a next record, the process returns to step S433.

  Returning to FIG. 29, in step S408, the icon color icon determined in step S406 is displayed only for the record in which icon display is permitted in step S407. The icon display routine is the same as that shown in FIG.

If the arbitrary color classification function button 162 is pressed in step S401, an arbitrary color classification display process is performed, and the process proceeds to step S409 due to the conditional branch in step S402.
In the arbitrary color-coded display processing, only the equipment of the type displayed at the top of the display equipment column 113 shown in FIG. 15 is displayed as an icon, and each icon is a colored field (T in FIG. 3) of the equipment specification table 12. Color) depending on the value of the column.

FIG. 41 shows a flowchart of the reference point correction processing routine S520. Now, a procedure for changing the reference point 191 at the position of the point 191 to the new point 192 in the route map shown in FIG. 42 will be described as an example.
Since the reference point is not directly displayed on the route map, in this example, the reference point where the equipment is installed is selected as the reference point 191. For this reason, an icon is displayed at the position of the reference point 191 in FIG.

Returning to FIG. 41, in step S521, when the operator clicks the position of the new point 192 on the route map displayed on the display 4 with the mouse 9, the device coordinates on the clicked display 4 are acquired.
In step S522, the device coordinates of the new point 182 acquired in S521 are converted into latitude and longitude coordinates. The conversion method is the same as that of the latitude / longitude acquisition routine S301 shown in FIG.

In step S523, the specification information of the reference point distance target 191 to be moved to the new point 192 designated in step S521 is input. A reference point specification information input window is shown in FIG.

A record having a code and a government building / toll gate type is selected, and a record having the same code as the government building / toll gate code of each selected record is selected from the government building / toll gate master table shown in FIG. . Then, a government building / toll gate name input menu 195 is generated using a list of government building / toll gate names of records selected from the government building / toll gate master table.

  When the operator selects any government building / toll gate name from the government building / toll gate name input menu 195 and inputs a lane number in the lane number input field 196, in step S524, from the reference point table 15 shown in FIG. A record having the route code and lane number input in S523 and the government building / toll gate code corresponding to the government building / toll gate name selected in step S523 is selected. The latitude and longitude acquired in step S522 are recorded in the center latitude field (E column) and the center longitude field (F column) of the selected record.

FIG. 44 shows a route map after correcting the position of the reference point. In the present embodiment, the distance marker correction process S510 and the reference point correction distance S520 update the contents of the distance marker table 14 and the reference point table 15, respectively, and execute these processes S510 and S520. However, the position of each facility once determined, that is, the position of the icon is not updated. Therefore, in order to recalculate the icon display position of the equipment already captured in the equipment specification table 12, a facility position recalculation process S604 described later shown in FIG. 50 is performed.
FIG. 44 is a route map after updating the icon position of the equipment arranged at the position of the reference point 191 by performing the facility position recalculation process S604 after correcting the position of the reference point 191.

  Returning to FIG. 36, when the facility position correction function is selected in the correction target selection window, the process proceeds to the facility position correction processing routine S530 by the conditional branch in step S503 of the flowchart shown in FIG. FIG. 45 shows a flowchart of the facility position correction processing routine S530. In the route map of the large scale (1/320 to 1/800), the equipment 201 of the route map is changed to be displayed at the new point 202 as shown in FIG. 46, and the route of the small scale (˜1 / 6250) is changed. In the figure, as shown in FIG.

In step S531, when the operator clicks the position of the new point 202 for the large scale route map on the route map displayed on the display 4 with the mouse 9, the device coordinates on the clicked display 4 are acquired.
In step S532, the device coordinates of the new point 202 acquired in S531 are converted into latitude and longitude coordinates. The conversion method is the same as that of the latitude / longitude acquisition routine S301 shown in FIG.

  In step S533, the specification information of the equipment 201 to be moved to the new location 202 specified in step S531 is input. The facility specification information input window is shown in FIG.

When the operator clicks the position of the new point 211 for the small scale route map on the route map displayed on the display 4 with the mouse 9, the device coordinates on the clicked display 4 are acquired.
In step S535, the device coordinates of the new location 211 acquired in S534 are converted into latitude and longitude coordinates. The conversion method is the same as that of the latitude / longitude acquisition routine S301 shown in FIG.

In step S536, the record having the registration number input in step S533 is selected from the facility position table 16 shown in FIG. The latitude / longitude acquired in step S532 is recorded in the center latitude 1 field (B column) and the center longitude 1 field (C column) of the selected record, and the center latitude 2 field (D column) and center longitude 2 field of this record are recorded. The latitude / longitude acquired in step S535 is recorded in (E column).
By the facility position correction processing routine S530, the latitude and longitude of the display position of the icon of the same facility can be made different between the large scale route map and the small scale route map. Therefore, in the large-scale route map, the icon is displayed as close as possible to the actual equipment layout position, while in the small-scale route map where icons are likely to overlap with each other in the adjacent equipment, the icon positions of adjacent equipment are unlikely to overlap. It is possible to improve the operator's work environment by rearranging the display position.

  Returning to FIG. 15, the route map display screen includes a detailed setting button 116. Due to the conditional branching in step S3 of the flowchart shown in FIG. 13, the process proceeds to the setting routine S60.

The toll gate position recalculation range designation window is provided with a route name input field 238 and a government building / toll gate name input field 239. In these input fields, if the operator inputs the name of the route where the equipment to be recalculated and the name of the government building / toll gate are entered, this is accepted and the range for recalculating the equipment placement position is specified. .

In step S632, the facility specification table 12 has the route code and the government building / toll gate code corresponding to the route name and the government building / toll gate name input in step S631, and the value of the government building / toll gate type is the fee. Select the facility record that is “2” meaning the place.
In step S633, the government office / toll gate code recorded in the government office / toll gate code field (column I in FIG. 3) of each facility record selected in step S632 is recorded in the reference point table 15. The obtained latitude / longitude information is acquired and determined as the latitude / longitude of the arrangement position of each facility.
In step S634, the latitude and longitude recorded in the facility position table 16 are corrected to the values determined in step S633 for each of the facilities in the facility specification table 12 selected in step S632.

  When the government building position recalculation function is selected in the recalculation target selection window of FIG. 52, the processing moves to the government building position recalculation routine S614 by the conditional branch in step S611 of FIG. In the government building position recalculation routine S614, among the latitude and longitude information recorded in the facility position table 16 shown in FIG. 10, the latitude and longitude information of the equipment whose arrangement position is specified based on the reference point based on the position of the government building is recalculated. I do. Processing similar to the toll gate position recalculation routine S613 is performed except that the reference point where the target facility is installed is the government building. Therefore, description is omitted for simplicity.

FIG. 60 is an overall flowchart of the distance marker data creation program 41 according to the embodiment of the present invention, and FIG. 61 is an operation explanatory diagram of the distance marker data creation program.
The facility information management program 11 described above converts the distance information of each facility into latitude / longitude information using the distance information and latitude / longitude information of each distance marker recorded in the distance marker table 14, thereby The two-dimensional position of each equipment in the figure is acquired. In addition, as described above, the latitude / longitude information of the facility is calculated by interpolating the latitude / longitude information of two distance markers sandwiching the facility. Here, the route on which the equipment is installed does not necessarily include a straight section but also a curved section. Therefore, as many distance indicator data as possible are necessary to accurately display the position of the equipment in the route map.

However, a great deal of effort is required to input the distance information and latitude / longitude information of a number of distance markers into the computer 1 in association with each other. The distance marker data creation program 41 easily creates distance marker data including the latitude and longitude information of each distance marker set at a predetermined distance marker interval P along the route by the method described below. Make it possible.
In step S81, a map (map 300 in FIG. 61) including a route map on which a distance marker is to be installed is displayed on the display 4. The operation for displaying the map is the same as the map display routine shown in FIG.
In step S82, when the operator designates the starting point of the route R with one point on the map 300 with the mouse 9, this instruction is accepted and coordinate information of the position information of that point is acquired. In the map 300 shown in FIG. 62, it is assumed that the point 301 is the starting point.

In step S83, a circle 302 centered on the starting point 301 specified in step S82 and having a predetermined distance marker interval P as a radius is displayed on the map 300. Then, since it can be seen that the position of the next distance mark 311 that is separated from the starting point by the predetermined distance mark interval P is near the intersection of the circle 302 and the route R, the position of the next distance mark 311 can be easily determined. Can be determined.
In step S84, when the operator designates the position of the next distance marker 311 with the mouse 9, this instruction is accepted and coordinate information of the position information of the point is acquired.
In step S85, the coordinate information acquired in step S84 is converted into latitude and longitude information. Since this process is the same as the latitude / longitude acquisition routine S301 described with reference to FIG. 26, the description is omitted for simplicity.

  In step S86, the operator inputs the specification data of the distance marker whose position has been specified in step S84, that is, the route code, point name, direction code, and distance value to be recorded in the distance marker table 14 shown in FIG. . When these specification data are received, a new record of the distance marker table 14 is generated from the input item data and the latitude / longitude information acquired in step S85, and added to the distance marker table 14.

In step S87, a circle 312 is displayed on the map 300 with the position of the distance marker 311 designated in step S84 as a center and a predetermined distance marker interval P as a radius. Then, since the position of the next distance marker 321 that is separated from the distance marker 311 by the predetermined distance marker interval P is also near the intersection of the circle 312 and the route R, the position of the next distance marker 321 Can be easily determined.
Thereafter, steps S84 to S88 are repeated until the distance markers to be input are exhausted, and new data is sequentially added to the distance marker table 14.
