  A printer 14 constituting selection result output means can be connected to the control system 15, and the simulation result is printed on a predetermined paper 18 (not shown) and output. As the printer 14, a color printer or a color copying machine is used.

  FIG. 2 is a block diagram illustrating a configuration example of a control system of the design support apparatus 100. The design support apparatus 100 shown in FIG. 2 is a control system that can simulate on the 3D map information system the installation position of a radio station, selection of a radio channel route, examination of interference interference, relay method and position, position of a reflector, and the like. 15.

  The control system 15 has a system bus 51. The system bus 51 includes a ROM (Read Only Memory) 52, a RAM (Random Access Memory) 53, an image processing means 54, a CPU (Central Processing Unit) 55, a hard disk (hereinafter referred to as HDD) 56, an I / O. An interface 57, a map memory 58, and an inappropriate place memory 59 are connected.

  The ROM 52 stores system program data DP for controlling the design support apparatus 100. The RAM 53 is used as a work memory, and for example, temporarily stores control commands, system activation programs, and the like when the system is activated. When the power is turned on, the CPU 55 reads the system program data DP from the ROM 52 to the RAM 53, starts the system, and controls the entire design support apparatus based on the operation data D3 from the keyboard 12 or the mouse 13. The

  The HDD 56 constitutes a database, and stores various design conditions and guidelines (hereinafter referred to as design data D12) related to the design of the microwave multiplex radio channel, and selection result information thereof. The above-described map memory 58, inappropriate place memory 59, and the like may be configured in the HDD 56.

  The map memory 58 stores map data D11 for displaying a candidate construction area map read from the CD-ROM 16 for configuring the three-dimensional map information system, and display data D2 for displaying a high-low cross-sectional view. The unsuitable land memory 59 stores unsuitable land data D13 for displaying a construction unsuitable area map read from the CD-ROM 17 for constituting the three-dimensional map information system.

  In addition, in the unsuitable location memory 59, substation installation information held by the electric power company, existing microwave transmission and reception base information, and the like may be described. Based on this information, it becomes possible to plot the substations of power companies and existing microwave transmission and reception bases together with the inappropriate areas on the 3D map information system. DRAM, SRAM, or the like is used for the map memory 58, the inappropriate place memory 59, and the like.

  The image processing unit 54 synthesizes the construction candidate area map display map data D11 read from the map memory 58 and the unsuitable area map display unsuitable area map display D13 read from the unsuitable area memory 59 to obtain a wireless line. Image processing is performed so as to construct a three-dimensional map information system for route selection. Further, when the image processing means 54 displays a high-low cross-sectional view of a wireless channel route connecting two points of the microwave multiplex radio equipment based on the determination result obtained from the CPU 55, an elevation difference is displayed in the high-low cross-section display video. And image processing is performed to display a line of sight. Thereby, the pass / fail of the wireless channel route between the transmission (transmission) point and the reception point of the microwave multiplex radio equipment can be simulated on the three-dimensional map information system.

  The ROM 52, the RAM 53, and the CPU 55 constitute a determination unit 50, and determines whether or not the position of the microwave multiplex radio equipment and the design conditions for the radio line route are met. For example, the CPU 55 compares the geographical condition of the candidate area of the radio channel route with the design condition of the microwave multiplex radio equipment to determine whether or not the geographical condition satisfies the design condition. Geographical conditions include location information such as a conservation forest for water source cultivation, a vast paddy field, the sea, and a large water surface.

  The ROM 52 described above stores determination program data DP ′ in addition to the system program data DP. In the RAM 53, map data D11 related to the geographical conditions of the candidate area for the wireless channel route and design data D12 related to the design conditions of the microwave multiplex radio equipment are developed. The CPU 55 has a comparison function, and compares the geographical condition of the candidate area of the radio channel route developed in the RAM 53 with the design condition of the microwave multiplex radio equipment to determine whether the geographical condition satisfies the design condition. Determine.

  The CPU 55 receives the map data D11 and the design data D12, the geographical conditions of the candidate area of the radio channel route connecting one or the other point of the microwave multiplex radio equipment and the relay point, and the design conditions of the microwave multiplex radio equipment, Are compared to determine whether the geographical condition satisfies the design condition. When it is determined that the geographical condition does not satisfy the design condition, an image is displayed so as to prompt the user to change the wireless channel route.

  For example, when a straight line connecting a transmission (transmission) point and a reception point of a microwave multiplex radio equipment is close to an inappropriate area or within an allowable separation distance, a warning is generated. . Although not shown, an audio unit may be incorporated in the control unit 15 so that changes, warnings, and the like are output as audio.

  An I / O interface 57 is connected to the system bus 51 described above. A keyboard 12, a mouse 13, a monitor 11, and a printer 14 are connected to the I / O interface 57. The keyboard 12 or the mouse 13 is operated so as to set a relay point between one and the other points of the microwave multiplex radio equipment based on the determination result obtained from the CPU 55.

  In this case, if it is determined that the geographical condition of the candidate area of the wireless channel route connecting the two points does not satisfy the design condition of the microwave multiplex radio equipment, the construction candidate that avoids the microwave inappropriate land A relay point can be set between one point and the other point of the microwave multiplex radio equipment.

  An unsuitable area display means, which is a software function of the CPU 55, is used for the monitor 11. On the construction candidate area map on the screen of the monitor 11, a protection forest that is not preferable as a microwave multiplex wireless line route, a vast paddy field Characters or pictographs such as a zone, the sea, and a large water surface are superimposed and displayed.

  Further, the display data D2 based on the determination result is inputted from the CPU 55 by the point-to-point selection means which is a software function of the CPU 55, and a high-low cross-sectional view of the wireless line route connecting the two points of the microwave multiplex radio equipment is displayed. . For example, when a transmission (transmission) point and a reception point of a microwave multiplex radio equipment are connected by a straight line, a topographic map of a cross section partitioned by the straight line is displayed in another window. You may make it the topographical map which shows a high and low cross section pop-up display on the same screen.

  While displaying this high-low cross-sectional view, if the straight line connecting the transmission (transmission) point and reception point of the microwave multiplex radio equipment passes through the cross-sectionally displayed mountain or building, a warning is issued to the user To be made. The warning is displayed by character information or pictographic information. In the topographic map of the cross section partitioned by a straight line connecting the transmission point and the reception point of the microwave multiplex radio equipment, the altitude difference and the possibility of line of sight are displayed. Thereby, the pass / fail of the wireless channel route between two points can be simulated on the three-dimensional map information system.

  The printer 14 is controlled by the selection result output means which is a software function of the CPU 55, and based on the print data D4, the coordinate position of the transmission point and the reception point satisfying the design conditions for the microwave multiplex radio equipment, the location information of the location, etc. It is made to print out.

  FIG. 3 is a conceptual diagram showing a configuration example of the microwave radio network design system 200. The microwave radio network design system 200 shown in FIG. 3 is a function embodied in the design support apparatus 100 and does not intend to fully automate the radio circuit route. It is a system that presents recommended routes for books and ultimately asks for human judgment. Therefore, a mirror check by a human system is a minimum requirement.

  The microwave radio network design system 200 is a system in which the three-dimensional map information system 31, which is existing software, is overwritten with the conditions for designing the microwave multiplex radio network, its guidelines, and the like. In this example, the map data D11 and the display data D2 are read from the map memory 58 constituting the three-dimensional map information database (DB), and are expanded in the memory area of the RAM 53, for example. On the other hand, unsuitable place data D13 is read from the unsuitable place memory 59 constituting the microwave unsuitable place database, and the design data D12 is read from the HDD 56 constituting the microwave line information database and combined on the memory area. It is made like.

  In the memory area 32 into which the microwave multiplexed radio line information is plugged in, an inappropriate area display means 33, a point-to-point selection means 34, and a selection result output means 35 constituted by the CPU 55 and software are constructed. The unsuitable area display means 33 reads out the unsuitable place data 13 from the unsuitable place memory 59, and controls the display of the monitor 11 based on the unsuitable place data 13. The point-to-point selection means 34 is provided with the keyboard 12 and the mouse 13. Display control is performed based on operation data D3 based on the operation.

  The selection result output means 35 stores the microwave line information in the HDD or outputs the print data D4 to the printer 14. For example, a selection result sheet 18 describing the wireless line route, location, etc. on the construction candidate map is displayed. It is made to print out. In this way, by simulating various conditions necessary for designing a microwave multiplex radio link on the three-dimensional map information system 31, it is possible to minimize the number of times of going to the site. In particular, it is possible to set an appropriate line route in a short time by simulating the installation method of the relay method, the repeater, and the reflector.

  FIG. 4 is a diagram showing a display example of a construction candidate area map on the monitor 11. According to the display example of the construction candidate area map shown in FIG. 4, the mountains Y1, Y2, Y3, Y4 are displayed in almost four directions of the screen, and the large paddy field T1 is displayed in the center, and the mountain Y2 A paddy field T2 is displayed during Y3. In the figure, five peaks Y1, Y2, Y3, Y4, Y5 are indicated by contour lines. The image of the construction candidate area map is displayed on the monitor 11 based on the map data D11 and the inappropriate land data D13.

  In the figure, a protection forest W1 for water source cultivation is displayed at the foot of the mountain Y2, and a protection forest W2 for water source cultivation is also displayed at the foot of the mountain Y3. A river R1 is located between the mountains Y1 and Y2, a river R2 is located between the mountains Y12 and Y3, a river R3 is located between the mountains Y3 and Y4, and a river R4 is located between the mountains Y1 and Y5. Mountain Y4 and mountain Y5 are connected to each other.

  Such a construction candidate area map screen is displayed on the monitor 11 by the 3D map information system 31 which is the existing software and the inappropriate area display means which is the software function of the CPU 55. The conservation forests W1 and W2 for water source recharge are unfavorable areas as microwave multiple radio channel routes. Paddy fields T1 and T2 are also unfavorable areas for microwave multiplex radio line routes.

FIG. 5 is a diagram showing a display example when setting the microwave multiplex radio equipment on the construction candidate area map screen.
According to the display example at the time of setting the microwave multiplex radio equipment shown in FIG. 5, the reception point (first point) P1 of the microwave multiplex radio equipment is set at the foot of the mountain Y2, and the microwave is at the top of the mountain Y4. A transmission point (second point) P2 of the multiplex radio equipment is set. In the figure, these two points are connected by a wavy line.

  The reception point P1 and transmission point P2 of these facilities include a case where it cannot be moved depending on design conditions such as ownership of real estate. On the left side of the wavy line connecting the two points, there are paddy fields T1 which are not preferable as a wireless line route and protected forests W1 and W2 for water source cultivation. Accordingly, since the reception point P1 and the transmission point P2 cannot be connected by a straight line, it can be understood from the simulation result that the wireless channel route is not suitable. It is necessary to execute a selection simulation that bypasses this area.

FIG. 6 is a diagram illustrating a display example when a wireless line route is detoured on the construction candidate area map screen.
According to the display example at the time of detouring the wireless line route shown in FIG. 6, a temporary reception point (third point) P3 ′ of the microwave multiplex radio equipment is set at the foot of the mountain Y1. The temporary reception point P3 ′ becomes the relay point P3 when the design condition is satisfied. The reception point P3 ′ and the transmission point P2 at the peak of the peak Y4 are connected by a straight line selection means 34.

  In the figure, these two points are connected by a wavy line. Since the left side of the wavy line connecting the two points is far away from the paddy field T1 and the conservation forests W1 and W2 for water source cultivation, in a two-dimensional plane, it is a preferable area as a wireless line route. There is a mountain Y4 and a continuous mountain Y5. Therefore, it is necessary to simulate whether or not the mountain Y5 becomes an obstacle when looking at the mountain-top receiving point P3 'of the mountain Y1 from the peak transmission point P2 of the mountain Y4.

  FIG. 7 is a diagram illustrating a display example of a high-low cross-sectional view of a wireless line route. According to the display example of the cross-sectional view of the wireless channel route shown in FIG. 7, the reception point P3 ′ of the microwave multiplex radio equipment temporarily set at the foot of the mountain Y1 and the transmission point P2 at the top of the mountain Y4 are straight lines. When connected at, an image of the topographic map of the cross section partitioned by the straight line is displayed on the monitor 11 based on the display data D2.

  In this high and low sectional view, the height of the steel tower, which is a microwave multiplex radio equipment, is incorporated, and the reception point P3 'and the transmission point P2 are connected by a straight line by the point-to-point selection means 34. In the display screen, for example, an altitude scale is displayed in units of 50 m on the vertical axis. The horizontal axis is a scale depending on the separation distance between the two points P1 and P2. In this example, the elevation of the reception point P3 'is 10 m, and the peak Y4 is 250 m. The elevation difference between the reception point P3 'and the transmission point P2 is 240 m.

  In the figure, these two points are connected by a solid line (straight line). In this example, in the straight line connecting the two points, the mountain Y4 and the continuous mountain Y5 are obstacles. Since it is impossible to connect the reception point P3 'and the transmission point P2 with a straight line, it can be seen from the simulation results that the wireless channel route is not suitable. Therefore, it is necessary to further execute a selection simulation of another wireless line route that bypasses the mountain Y5.

FIG. 8 is a diagram showing a display example when a radio channel route is selected on the construction candidate area map screen.
According to the display example at the time of selecting the radio channel route shown in FIG. 8, the relay point P3 of the microwave multiplex radio equipment is set at the peak of the peak Y1. This relay point (third point) P3 and the transmission point P2 at the summit of the mountain Y4 are connected by a straight line selection means 34. Further, the relay point P3 and the reception point P1 at the foot of the mountain Y2 are connected by a straight line by the point-to-point selection means 34.

  In the figure, these two points are connected by a wavy line. Since the left side of the wavy line connecting the two points is far away from the paddy field T1 and the protection forests W1 and W2 for water source recharge, it is a preferable area as a wireless channel route in a two-dimensional plane. Also, the mountain Y4 and the mountain Y5 that continues from the peak are in a position to look down on the eye. Therefore, when looking from the summit transmission point P2 of the mountain Y4 to the relay point P3 of the summit of the mountain Y1, the mountain Y5 is not an obstacle and is a preferable area as a wireless channel route.

  As described above, the relay point P3 is set at the peak of the mountain Y1 between the peak receiving point P1 of the peak Y2 and the peak transmission point P2 of the peak Y4 given in FIG. A circuit route can be selected.

  Next, an operation example of the design support apparatus 100 will be described for the information processing method according to the present invention. FIG. 9 is a flowchart illustrating an operation example of the design support apparatus 100.

  In this embodiment, it is assumed that design information of microwave multiplex radio equipment is processed. Further, when a candidate for a wireless channel route connecting the two points P1 and P2 is extracted based on the design condition input earlier, the geographical condition of the candidate region for the wireless channel route connecting the two points P1 and P2 is determined. It is determined whether or not the design conditions for the microwave multiplex radio equipment are satisfied. If it is determined that the conditions are not met, a relay point is set between one and the other points of the microwave multiplex radio equipment. To be set.

  Note that map data D11 and display data D2 for constructing a three-dimensional map information system are prepared in advance. In this example, existing map software is used for the CD-ROM 16. The CD-ROM 16 describes latitude information and longitude information, and map information such as mountains and rivers is managed in absolute positions. Further, when the power is turned on, the CPU 55 reads the system program data DP from the ROM 52 to the RAM 53, starts the system, and controls the entire design support apparatus based on the operation data D3 from the keyboard 12 or the mouse 13. To be made. In this example, the description will be made separately for the case where the geographical condition visibility condition satisfies the design condition and the case where they do not satisfy the design condition.

  Under these operating conditions, in step A1 of the flowchart shown in FIG. 9, the CPU 5 shows the map data D11 for the construction candidate area map of the microwave multiplex radio equipment and the high-low cross-sectional view of the radio line route connecting the two points P1 and P2. The display data D2 for displaying is input. For example, a CD-ROM 16 is attached to the control system 15, and map data D 11 and display data D 2 are read from the CD-ROM 16 and stored in the map memory 58. The control system 15 is equipped with a CD-ROM 17 and reads from the CD-ROM 17 unsuitable land data D13 such as an unfavorable water source rehabilitation forest, a vast paddy field, the sea, a large water surface, etc. And stored in the inappropriate place memory 59.

  Next, in step A2, the CPU 55 controls the image processing means 54 and the monitor 1 so as to display the microwave multiplex radio equipment construction candidate area map on the screen. The image processing means 54 combines the construction candidate area map display map data D11 read from the map memory 58 and the unsuitable area map display unsuitable area data D13 read from the unsuitable area memory 59 to obtain a wireless line. Image processing is performed so as to construct a three-dimensional map information system for route selection.

  According to the display example shown in FIG. 4, the construction candidate area map screen is displayed on the monitor 11 by the 3D map information system 31 that is the existing software and the inappropriate area display means that is the software function of the CPU 55. . In this example, mountains Y1, Y2, Y3, Y4 are displayed in almost four directions on the screen, a large paddy field T1 is displayed in the center, and a paddy field T2 is displayed between the mountains Y2 and Y3. Is done. In the figure, five peaks Y1, Y2, Y3, Y4, Y5 are indicated by contour lines. The image of the construction candidate area map is displayed on the monitor 11 based on the map data D11 and the inappropriate land data D13.

  In this example, the protection forest W1 for water source cultivation is displayed at the foot of the mountain Y2, and the protection forest W2 for water source cultivation is also displayed at the foot of the mountain Y3. A river R1 is located between the mountains Y1 and Y2, a river R2 is located between the mountains Y12 and Y3, a river R3 is located between the mountains Y3 and Y4, and a river R4 is located between the mountains Y1 and Y5. Mountain Y4 and mountain Y5 are connected to each other.

  The monitor 11 displays on the screen a three-dimensional map for selecting a radio channel route by combining the construction candidate area map and the construction inappropriate area map output from the image processing means 54. At this time, the monitor superimposes and displays characters or pictographs for emphasizing the location of water source recharge protection forests, vast paddy fields, seas, large water surfaces, and the like. It should be noted that the substation installation information owned by the power company, the existing microwave transmission and reception base information, etc. may be read from the unsuitable area memory 59 and displayed over the construction candidate area map.

  According to the display example shown in FIG. 4, the protection forests W1 and W2 for water source recharge are areas that are not preferable as microwave multiple radio channel routes. Paddy fields T1 and T2 are also unfavorable areas for microwave multiplex radio line routes. An unsuitable area display means, which is a software function of the CPU 55, is provided on the monitor 11. On the construction candidate area map on the screen of the monitor 11, the protection forests W1 and W2 for water source cultivation that are not preferable as a microwave multiplex wireless line route, Characters or pictographs such as vast paddy fields T1 and T2, the sea, a large water surface, and the like are superimposed and displayed.

  Next, in step A3, the CPU 55 inputs a design condition for the microwave multiplex radio equipment. At this time, the user uses the keyboard 12 and the mouse 13 to arbitrarily set the microwave multiplex radio equipment installation information, the radio channel route selection information, the interference interference examination information, the relay method and its position information, The design conditions such as the position information of the reflector and the information related to the microwave inappropriate place are input. Design data D12 such as various design conditions and guidelines related to the design of these microwave multiplex radio links is read from the HDD 56 to the image processing means 54.

  Thereafter, in step A4, the CPU 55 performs an input process on two points P1 and P2 of a reception point (first point) P1 and a transmission point (second point) P2 on the construction candidate area map. For example, the user uses the keyboard 12 or the mouse 13 to input two points of the reception point P1 and the transmission point P2 on the construction candidate area map displayed on the monitor 11. The two points of the reception point P1 and the transmission point P2 are output to the CPU 55 as operation data D3. The CPU 55 is configured to input a wireless line route based on the operation data D3. The CPU 55 is configured to support extraction of a candidate for a wireless line route connecting the two points P1 and P2 based on the design conditions input by the keyboard 12 or the mouse 13.

  According to the display example shown in FIG. 5, the reception point P1 of the microwave multiplex radio equipment is set at the foot of the mountain Y2, and the transmission point P2 of the microwave multiplex radio equipment is set at the top of the mountain Y4. In this example, on the left side of the wavy line connecting the two points P1 and P2, there are unpreferable paddy fields T1 as a wireless channel route and protected forests W1 and W2 for water source cultivation.

  Then, the process proceeds to step A5, and the CPU 55 determines whether or not the position of the microwave multiplex radio equipment and the design condition for which the radio line route is determined are met. For example, the discrimination program data DP ′ is read from the ROM 52 and developed in the RAM 53. The CPU 55 uses the comparison function to compare the geographical condition of the candidate area of the radio channel route developed in the RAM 53 with the design condition of the microwave multiplex radio equipment based on the discrimination program data DP ′ and to design the geographical condition. It is determined whether or not the condition is satisfied. The geographical conditions include location information such as protected forests W1 and W2 for water source cultivation, vast paddy fields T1 and T2, the sea, and a large water surface.

[When design conditions are satisfied]
If it is determined in step A5 that the geographical condition of the candidate area for the wireless channel route satisfies the design conditions for the microwave multiplex radio equipment, the process proceeds to step A6 to connect the two points P1 and P2. Displays a high-low cross-sectional view of the wireless channel route. In the image processing means 54, when displaying a high-low cross-sectional view of the wireless channel route connecting the two points P 1, P 2 of the microwave multiplex wireless equipment based on the determination result obtained from the CPU 55, Image processing is performed to display the difference and line of sight. A line-of-sight line refers to a wireless line route that connects two points P1 and P2 in an elevation cross-sectional view. When the line of sight passes through an obstacle such as a mountain or a building, it is not suitable as a wireless channel route. This design condition is referred to as the prospect condition below.

  Then, the process proceeds to step A7, where the CPU 55 compares the line-of-sight condition in the high and low cross section of the wireless channel route with the design condition of the microwave multiplex radio equipment to determine whether the line-of-sight condition satisfies the design condition. . If it is determined that the line-of-sight condition in the high and low cross-section of the wireless channel route satisfies the design condition of the microwave multiplex wireless equipment, the process proceeds to step A9.

[When design conditions are not satisfied]
If the CPU 55 determines in step A5 that the geographical condition of the candidate area for the wireless channel route does not satisfy the design conditions for the microwave multiplex radio equipment, the CPU 55 determines whether the geographical condition for the microwave multiplex radio equipment is satisfied in step A8. The change of the wireless line route is prompted, and the monitor 11 is controlled to display an image so as to guide (warn) the relay point between one and the other points of the microwave multiplex wireless equipment.

  According to the display example shown in FIG. 5, the straight line connecting the reception point P1 and the transmission point P2 of the microwave multiplex radio equipment is close to the inappropriate area or within the allowable separation distance. Is made to generate. In this example, since there is an inappropriate area on the left side of the straight line connecting the reception point P1 and the transmission point P2, it can be seen from the simulation result that the wireless line route is not suitable. It is necessary to execute a selection simulation that bypasses this area.

  In response to this warning, the user is operated to set a relay point between one and the other points of the microwave multiplex radio equipment using the keyboard 12 or the mouse 13. If it does in this way, it is a construction candidate area | region which avoided the microwave unsuitable land, Comprising: A relay point can be set between the one and other points of the said microwave multiplex radio equipment.

  According to the display example at the time of detouring the wireless channel route shown in FIG. 6, the monitor 11 displays so as to set the temporary relay point P3 'of the microwave multiplex radio equipment at the foot of the mountain Y1. This relay point (third point) P3 'and the transmission point P2 at the summit of the mountain Y4 are connected by a straight line selection means 34.

  Then, returning to step A5, the CPU 55 compares the geographical conditions of the candidate area of the radio channel route between the transmission point P2 and the relay point P3 ′ of the microwave multiplex radio equipment with the design conditions of the microwave multiplex radio equipment and compares them. It is determined whether or not the geographical condition satisfies the design condition. In this example, the left side of the wavy line connecting the two points P2 and P3 ′ is far away from the paddy field T1 and the protection forests W1 and W2 for water source cultivation. This is a preferable region. Since there is a mountain Y4 and a continuous mountain Y5, it is necessary to simulate whether the mountain Y5 becomes an obstacle when looking at the foot relay point P3 ′ of the mountain Y1 from the peak transmission point P2 of the mountain Y4. (See FIG. 6).

  Next, proceeding to step A6, the CPU 55 controls the monitor 11 so as to display a high-low cross-sectional view of the wireless line route connecting the two points P2 and P3 '. The image processing means 54 performs image processing so as to display an altitude difference and a line of sight in the high-low cross-section display video. At this time, the monitor 11 has a straight line connecting the relay point P3 ′ of the microwave multiplex radio equipment temporarily set at the foot of the mountain Y1 as shown in FIG. 7 and the transmission point P2 at the peak of the mountain Y4. At this time, an image of the topographic map of the cross section partitioned by the straight line is displayed based on the display data D2.

  In this example, the height of the steel tower, which is a microwave multiplex radio equipment, is incorporated, and the temporary relay point P3 'and the transmission point P2 are connected by a straight line by the point-to-point selection means 34. In this example, the elevation of the relay point P3 'is 10 m, and the peak Y4 is 250 m. The elevation difference between the relay point P3 'and the transmission point P2 is 240 m.

  Thereafter, the process proceeds to step A7, where the CPU 55 compares the line-of-sight condition of the wireless channel route with the design condition of the microwave multiplex radio equipment and determines whether the line-of-sight condition satisfies the design condition. To do. According to the display example shown in FIG. 7, in the straight line connecting the two points P2 and P3, the mountain Y4 and the continuous mountain Y5 are obstructed.

  In this example, since the relay point P3 'and the transmission point P2 cannot be connected by a straight line, it can be understood from the simulation result that the wireless line route is not suitable. Therefore, according to the display example of the cross-sectional view of the wireless channel route shown in FIG. 7, it is necessary to further execute a selection simulation of another wireless channel route that bypasses the mountain Y5.

  As described above, when it is determined that the line-of-sight condition in the high and low cross section of the wireless channel route does not satisfy the design condition of the microwave multiplex wireless equipment, the process returns to step A8 and the above-described processing is repeated. According to the display example at the time of selecting the radio channel route shown in FIG. 8, the relay point P3 of the microwave multiplex radio equipment is set at the peak of the peak Y1. This relay point (third point) P3 and the transmission point P2 at the summit of the mountain Y4 are connected by a straight line selection means 34. Further, the relay point P3 and the reception point P1 at the foot of the mountain Y2 are connected by a straight line by the point-to-point selection means 34.

  In this example, the left side of the wavy line connecting the two points P2 and P3 is far away from the paddy field T1 and the conservation forests W1 and W2 for water source cultivation. This is a preferred region. Also, the mountain Y4 and the mountain Y5 that continues from the peak are in a position to look down on the eye. According to the display example shown in FIG. 8, when looking from the summit transmission point P2 of the mountain Y4 to the relay point P3 of the summit of the mountain Y1, the mountain Y5 is not an obstacle and is a preferable area as a wireless channel route. . As described above, when the wireless line route that bypasses the mountain Y5 is extracted and it is determined that the line-of-sight condition in the high and low cross-section of the wireless line route satisfies the design condition of the microwave multiplexing wireless equipment, step A9 Migrate to

  In step A9, the CPU 55 executes result output and result storage processing. In this example, a relay point P3 is set at the summit of the mountain Y1 between the summit reception point P1 of the mountain Y2 and the summit transmission point P2 of the mountain Y4 given in FIG. A circuit route can be selected.

  For example, the printer 14 is controlled by a selection result output means that is a software function of the CPU 55, and the printer 14 receives the reception point P1, the transmission point P2, and the relay that satisfy the design conditions for the microwave multiplex radio equipment based on the print data D4. The coordinate position of the point P3, its location information, etc. are printed out on a predetermined paper 18. Selection result information and the like based on the simulation result are stored in the HDD 56.

  Thereafter, the process proceeds to step A10, and the CPU 55 determines the end. For example, the power-off information is detected and the microwave multiplex radio equipment design support process is terminated. If the power-off information is not detected, the process returns to step A3, the design condition is input, and the above-described processing is repeated.

  Thus, according to the design support apparatus 100 and the information processing method as the embodiment, when the design information of the microwave multiplex radio equipment is processed, the control system 15 uses the design conditions input by the keyboard 12 and the mouse 13. On the basis of the above, extraction of a wireless channel route candidate connecting the two points P1 and P2 is supported. In this example, the CPU 55 compares the geographical condition of the candidate area of the wireless line route with the design condition of the microwave multiplex radio equipment and determines whether the geographical condition satisfies the design condition. Based on the determination result obtained from the CPU 55, the monitor 11 displays a high-low cross-sectional view of the radio line route connecting the two points P2 and P3 of the microwave multiplex radio equipment.

  Therefore, the pass / fail of the radio channel route between the reception point P1 and the transmission point P2 of the microwave multiplex radio equipment can be simulated on the three-dimensional map information system. As a result, it is possible to select on an appropriate wireless line route desk before being dispatched to the site, and to assist in selecting a wireless line route. In addition, it is possible not only to select an appropriate wireless channel route from among the extracted wireless channel route candidates in a short period of time, but also to significantly reduce the number of visits to the site compared to the conventional method. Thereby, the said design support apparatus 100 can fully be applied to a microwave multiplex radio equipment design work.
