Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an obstacle check device for checking the presence or absence of an obstacle on a wireless reference road using a computer.
[0002]
[Prior art]
For example, when an antenna is provided by assembling iron poles and branch lines to provide a new wireless line, at the time of planning, whether or not there is a building such as a building or structure on the reference line of the new wireless line to be obstructed Is checked in advance. Specifically, a base station, which is two reference points, is entered on a map, and a reference line is drawn from a point at a certain distance from the base station, and there is a possibility that an obstacle will be on the reference line. Look for existing buildings, and if there is a building that may be an obstacle, plan the height and shape so that all structures can be identified regardless of the number of buildings. It is a common practice to check building information such as dimensions and to check one by one whether or not it actually becomes an obstacle.
[0003]
In addition, when there is a building that is to be newly established soon on the reference line of the wireless line that is to be newly established, conventionally, building information such as a plan view and an elevation view of the building is obtained and obstacles are identified. A check is made as to whether this is the case.
[0004]
As described above, check the buildings that may become obstacles one by one, set the base station at a position where a reference line can be drawn on a route without obstacles, and install a new wireless line ing.
[0005]
On the other hand, if there is a possibility that radio interference may occur with the construction of a new building such as a new construction, the current radio wave reception condition is surveyed in advance at the time of planning, a record is created, and a photograph of the surrounding area is created. I use it to help me decide what to do about it. Investigation of these current radio wave reception states and creation of records are usually performed by requesting specialized companies.
[0006]
[Problems to be solved by the invention]
Of the above-mentioned conventional methods, when a new line is established, a reference line is drawn on a map to search for obstacles caused by an existing building. Since it is necessary to obtain information one by one for all the structures and check them individually, there is a problem that it takes time and labor.
[0007]
Also, if there is a building to be constructed on the reference line drawn on the map, it is necessary to wait for information to be obtained until the contents of the construction plan are clearly determined, and it is determined whether or not it will be an obstacle It takes a long time to do so, which may cause problems such as delaying the plan for constructing the wireless line and extending the construction period.
[0008]
In addition, it is possible to obtain the details of the planned building that overlaps the reference line drawn on the map in a short time, and the height of the building is too high, Even if it could be judged immediately that it would be an obstacle to the reference line, what kind of laws and regulations would cause the building to be an obstacle to be built at a height that would be an obstacle In order to know the reason, it is necessary to check the restricted area and land use plan map, and when there are many buildings that become obstacles like this, it takes time and effort to find out Has problems.
[0009]
On the other hand, for the planned building that overlaps the reference line drawn on the map, we cannot wait for clear information on the contents of the construction, so we estimate the contents of the construction and check whether it will be an obstacle. If a wireless line is newly established according to the result, there is a possibility that the wireless line will be found to be subsequently obstructed by the newly constructed building. In this case, the newly established wireless line is cut off and suffers a failure, so that the reference line must be changed. As a result, it is necessary to newly establish a wireless line, and the iron poles and branch lines for the wireless line constructed earlier will be wasted, and when the iron poles and branch lines are to be removed, the removal work and disposal Disposal is costly, and installation of a new wireless line is costly, which causes a problem that the cost is multiplied.
[0010]
In addition, when investigating the possibility of radio interference caused by construction work when constructing a new building, etc., it is generally costly because a specialist contractor performs the check. There is a problem that it is.

[0033]
Based on the received condition setting data D1, the wireless reference road modeling processing unit 42 performs a modeling process for creating three-dimensional reference road coordinate data D4 indicating the reference road, and calculates the reference road coordinate data D4 as a three-dimensional model overlapping coordinate. It is transmitted to the unit 45 and the image data processing unit 47.
[0034]
The existing building modeling processing unit 43 performs a modeling process for creating three-dimensional regional current coordinate data D5 in the predicted area based on the received current map data D2, and converts the regional current coordinate data D5 into a three-dimensional model overlapping coordinate calculating unit. 45 and the image data processing unit 47.

[0036]
The three-dimensional model overlapping coordinate calculation unit 45 processes the received reference road coordinate data D4, the regional current coordinate data D5, and the regional planning coordinate data D6. First, the reference road coordinate data D4 and the current regional coordinate data D5 are compared, and the portion where the reference road represented by the standard road coordinate data D4 overlaps the current building in the predicted area represented by the local current coordinate data D5. Is calculated. If there are overlapping coordinates, the wireless line represented by the reference road will be obstructed by the existing building, and the three-dimensional display of the reference road and the obstructing building by changing the color or the like. The current failure coordinate data D7 is created, and the current failure coordinate data D7 is transmitted to the creation unit 46.

Further, the three-dimensional model overlapping coordinate calculation unit 45 compares the reference road coordinate data D4 of the received data with the regional planning coordinate data D6, and determines that the reference road represented by the reference road coordinate data D4 is the regional planning coordinate. A process is performed to calculate coordinates that overlap with a building that reflects the laws and regulations in the predicted area represented by the data D6 to the maximum. If there are overlapping coordinates, the wireless line represented by the reference road may be damaged in the future, and the color of the reference road and the building that fully reflects the laws and regulations will be changed. Then, the planned obstacle coordinate data D8 to be displayed is created and transmitted to the creating unit 46.
[0038]
The creating unit 46 performs data processing on the reference road coordinate data D4, the current regional coordinate data D5, and the current obstacle coordinate data D7 so that the three-dimensional display can be performed to create the current three-dimensional image data D9.

Data D12 and regional plan three-dimensional image data D13 are created, and the created three-dimensional image data D11 to D13 are output to the display device 5. Since the image data processing unit 47 is configured to create and output each of the three-dimensional image data D11 to D13 as described above, the operator can use the display device 5 to display the current map, the height and scale of the building. It is possible to independently and three-dimensionally display the map on the plan reflecting the laws and regulations for restricting the operation and the like and the reference road on which the check is being performed.

Any data according to the instruction from the device 2 is displayed on the screen.
[0041]
FIG. 2 is a flowchart for explaining the flow of the obstacle check processing on the reference road in the check device 1. The process in the check device 1 will be described in detail with reference to FIG.
[0042]
When the process is started by the check device 1, in step S1, an operator inputs an address of a base station or the like for setting a reference route using the input device 2, the height of an antenna installed at the address, and the reference route. Information on the condition setting for checking, such as the cross-sectional radius dimension, the address of the predicted area where it is desired to predict whether there is a building that is in the vicinity of the reference road and there is an obstacle to the reference road, and the like, is input, The input information is converted into data to be used as condition setting data D1 and sent to the input data processing unit 41. It should be noted that information on base stations and the like is configured so that at least two locations can be input and a check can be performed on one reference route. Is also good.
[0043]
Next, in step S2, based on the received condition setting data D1, the input data processing unit 41 uses the map data including the height information of the ground and the building in the designated predicted area from the city area electronic map DB31. To obtain the current map data D2 indicating the corresponding contents. Further, based on the condition setting data D1, based on the condition setting data D1, the input data processing unit 41 uses the use-specific / land use plan DB 32 to specify the name of the local area in the predicted area and the maximum limit of the building stipulated by law in each local area. The height and wall limit position information are searched, and plan data D3 indicating the corresponding contents is obtained. The input data processing unit 41 transmits the condition setting data D1 among the received data to the wireless reference road modeling processing unit 42, and transmits the current map data D2 to the existing building modeling processing unit 43, and outputs the current map data D2 and the plan. The data D3 is transmitted to the constructable height space modeling unit 44, respectively.
[0044]
Next, in step S3, the wireless reference road modeling processing unit 42 performs a modeling process of creating three-dimensional reference road coordinate data D4 indicating the reference road based on the received condition setting data D1, and performs reference road coordinate data D4. Is transmitted to the three-dimensional model overlapping coordinate calculation unit 45.
[0045]
Next, in step S4, the existing building modeling processing unit 43, based on the current map data D2 received from the input data processing unit 41, determines the ground of the predicted area and the existing building currently provided in the predicted area. Is performed to create the three-dimensional current state coordinate data D5, and the current state coordinate data D5 is transmitted to the three-dimensional model overlapping coordinate calculation unit 45.
[0046]
Next, in step S5, the constructable height space modeling processing unit 44 determines, based on the current map data D2 and the plan data D3 received from the input data processing unit 41, the ground in the predicted area specified in step S1, In addition to the three-dimensional display of buildings considered to be constructed at the highest height that can be built in the predicted area, the buildings whose scales have changed from the current ones are scaled according to city planning. Modeling processing is performed to create regional planning coordinate data D6 for color-coded display according to regulations so that the contents of laws and regulations can be understood, and the regional planning coordinate data D6 is transmitted to the three-dimensional model overlapping coordinate calculation unit 45.
[0047]
In step S6, the three-dimensional model overlapping coordinate calculation unit 45 compares the reference road coordinate data D4 received from the wireless reference road modeling processing unit 42 with the current regional coordinate data D5 received from the existing building modeling processing unit 43, and The reference road represented by the road coordinate data D4 is subjected to a process of calculating coordinates of a portion overlapping with the current building in the predicted area represented by the regional current coordinate data D5, and the reference road having an obstacle on the road is determined. The three-dimensional current obstacle coordinate data D7 indicating a building that becomes an obstacle is created. If the coordinates of the overlapping part do not exist, there is currently no building on the reference road in the predicted area, so the reference road with the obstacle on the road and the building that will be the obstacle Therefore, there is no content of the three-dimensional current obstacle coordinate data D7.
[0048]
In addition, when there is a coordinate of an overlapping portion, it is likely that a radio line indicated by the reference road may be damaged at present in the predicted area. The current obstacle coordinate data D7 is created. The current obstacle coordinate data D7 includes data for coloring the building that becomes the obstacle and the reference road that may be obstructed, for example, in red and yellow.
[0049]
In step S7, the three-dimensional model overlapping coordinate calculation unit 45 compares the reference road coordinate data D4 received from the wireless reference road modeling processing unit 42 with the regional planning coordinate data D6 received from the constructable height space modeling processing unit 44. Then, a process is performed to calculate the coordinates of a portion where the reference road represented by the reference road coordinate data D4 and the planned building according to the legislation represented by the regional planning coordinate data D6 overlap, and a future obstacle may be caused. Three-dimensional planned obstacle coordinate data D8 indicating a reference road having a possibility and a building that may become an obstacle is created. If there is no overlapped coordinate, there will be no obstacles on the reference road currently being checked in the predicted area in the future, so the reference road with obstacles on the road and the obstacle There are no buildings constructed within the limits of the laws and regulations, so that the contents of the planned obstacle coordinate data D8 do not exist.
[0050]
Further, if there is an overlapped coordinate, the wireless line indicated by the reference road may be damaged in the future, so the three-dimensional model overlapped coordinate calculator 45 calculates the planned obstacle coordinate data D8. create. To the planned obstacle coordinate data D8, data for coloring a reference road that may be damaged in the future, for example, red or yellow, is added.
[0051]
In step S8, the creating unit 46 performs data processing on the reference road coordinate data D4, the current regional coordinate data D5, and the current obstacle coordinate data D7 received from the three-dimensional model overlapping coordinate calculating unit 45, and stores the data in the current state in the predicted area. Current three-dimensional image data D9 for three-dimensionally displaying the state of the wireless reference path on which the check is being performed is created and transmitted to the display device 5.
[0052]
The creating unit 46 performs data processing on the received reference road coordinate data D4, regional planning coordinate data D6, and planned obstacle coordinate data D8, and states that the building is being constructed at the height of the constructable limit within the predicted area. , Creates plan three-dimensional image data D10 for three-dimensionally displaying a state in which the reference path of the wireless line is provided, and transmits it to the display device 5.
[0053]
In step S9, the display device 5 sequentially displays the received result data of the current three-dimensional image data D9 and the planned three-dimensional image data D10 according to an instruction of the operator. Here, when the current three-dimensional image data D9 is displayed on the screen, when the reference road is obstructed by the current building, the building that is the obstacle and the reference road on which the obstacle is on the road are: Colors and line types are changed from buildings and reference roads not related to other obstacles so that they can be identified at a glance. If the displayed reference road does not overlap the current building and the reference road is not obstructed by the current building, the reference road and the building are each displayed in a single color.
[0054]
Further, when the plan three-dimensional image data D10 is displayed on the screen of the display device 5, laws and regulations such as a use district and a city planning area are applied to the current building, and the current building has a high construction limit. And it is displayed as being constructed at the wall position. Buildings that have been constructed at the legal limit and changed from the current state are displayed in a different color from the building as it is even when legal regulations are applied. At the same time, the buildings displayed at the limit of the height that can be built are displayed in different colors according to the contents of regulations, such as restricted zones and regional districts in city planning.
[0055]
If the newly established wireless reference path is obstructed by at least one of the buildings displayed at the limit of the height that can be built, the graphic indicating the disturbed wireless reference path is: The display is changed so as to be distinguished at a glance by changing the figure and the color indicating the reference road which is not subject to obstacles.
[0056]
3 to 5 show an example of a screen display that is displayed on the display device 5 as a result. FIG. 3 shows that when the display device 5 performs a screen display based on the current three-dimensional image data D9 and a new reference route for a check target is newly established in the current predicted area, the reference route may be subject to any obstacle. A state without sex is shown. Here, for example, the reference road is painted in green, the building is painted in gray, and the shape is displayed in shades of color. Also, in FIG. 3, all the reference roads are shown by straight lines, but this is a display screen when the operator enters the setting conditions for the first time and the section radius of the reference road is set to zero. Is what it is. When a required numerical value larger than zero is input as the cross-sectional radius dimension of the reference path in accordance with conditions such as frequency, the reference path is represented by a shape having a cross-sectional area. The shape of the figure showing the reference path is exactly the same in the drawings showing the following screen displays.
[0057]
FIG. 4 shows another example of the screen display when the display device 5 performs the result display based on the current three-dimensional image data D9. In this example, the wireless communication device to be checked during the current predicted area is shown. When a reference road is newly established, a state where one reference road is obstructed by one building is shown. At this time, in FIG. 4, for the sake of explanation, the building that becomes an obstacle is hatched with diagonal lines, and the reference road that receives the obstacle is shown by a dotted line. The buildings that will be obstacles can be seen at a glance, such as by painting the different buildings in different colors, such as gray, and displaying their outlines in different shades of color, or by drawing the outlines in different colors. It can be displayed so that it can be determined. In addition, the reference road that receives the obstacle can be displayed in a different color and line type, such as a red dotted line, and the reference road that does not receive the obstacle can be displayed in green.
[0058]
Further, when the reference road is displayed in a shape having a cross-sectional area, the reference road receiving the obstacle is a discontinuous red figure, and the reference road not receiving the obstacle is a continuous green figure. It can also be displayed in colors and figures. Regarding a figure showing a reference path having a cross-sectional area, a display shape that enables determination of the presence or absence of an obstacle is exactly the same in the drawings showing the following display screens.
[0059]
FIG. 5 shows an example of a screen display when the display device 5 performs the result display based on the plan three-dimensional image data D10. Buildings that differ from the current situation are hatched when the regulations are applied to the maximum extent, and are shown so that they can be distinguished at a glance from other buildings that have not changed from the current situation. Paint buildings in different colors, such as light red for buildings that are displayed as limits and gray for buildings that have not changed from the current state, or draw the outline with shades of color, or draw outlines with different colors It may be displayed. In addition, the buildings that are displayed with the limit of the height that can be built and the position of the wall surface may be displayed in different colors according to the contents of the restricted area or the local area. It is possible to determine at a glance whether the height is determined by the regulations.
[0060]
Here, of the reference roads of the radio line to be newly established, the reference roads on which the buildings indicated as being constructed under the limits of laws and regulations are on the road are dotted lines, and the reference roads on which there are no obstacles on the roads are Although it is displayed as a straight line, on the actual screen, the reference route that is subject to obstacles should be displayed in a different color and line type, such as a dotted red line, and the reference route that is less likely to be affected is a green straight line. As a result, it is possible to display such that the reference road suffering the obstacle can be instantaneously determined.
[0061]
As described above, on the display screen displayed on the display device 5, when there is a three-dimensionally displayed current building that may be overlapped with the reference road and become an obstacle, Display the building that becomes an obstacle in a different display format, such as changing the color of the building that is unlikely to cause obstacles, and color-code the reference road that is likely to be obstructed with the reference road that is less likely to be obstructed. By displaying three-dimensional images in different display formats, such as whether or not there is an obstacle on the reference road in the current predicted area, what the obstacle is, where it is, and how high the obstacle is. Whether it exists or not can be determined at a glance.
[0062]
In addition, buildings that are displayed as being constructed at the maximum limits of laws and regulations, such as the height that can be constructed and the position of the wall surface, are displayed three-dimensionally by color according to the type of the regulations, and a standard where obstacles are on the road. The road is color-coded and three-dimensionally displayed with the reference road where no obstacles are on the road, so that the radio line to be newly established is likely or unlikely to be obstructed in the future, and what is the obstacle. It is now possible to determine at a glance what the obstacle is, what height the obstacle is, and what laws and regulations are the reasons for the height.
[0063]
Next, in step S10, an input screen for inputting information relating to the condition setting is displayed on the display device 5, whereby the result display in step S9 indicates that the radio line to be newly established indicated by the reference road is currently Alternatively, if there is a possibility of being obstructed in the future, the building is constructed so that a building that becomes an obstacle can be avoided and a detour reference road can be found. That is, an input screen for inputting information for setting the next candidate reference road is displayed, which is input as desired by the operator. In step S9, if there is no obstacle to the wireless reference road to be newly established and it is not necessary to search for a new candidate reference road, there is no input by the operator.
[0064]
In step S11, in step S10, information on the condition setting for setting the base station for the new reference road and the predicted area is input, and the condition setting data D1, which is the data, is input to the input data processing unit 41. It is determined whether or not it is. When the condition setting data D1 has been input to the input data processing unit 41, the determination result in step S11 is YES, the process returns to step S2, and a new reference road and a candidate for a predicted area are subjected to the above-described steps S2 to S9. The process is repeated.
[0065]
Then, the detour reference road, which is a new reference road, is displayed so as to be superimposed on the display screen displayed on the display device 5 in step S9 in the previous processing, whereby the original reference road is And the detour reference road can be checked at the same time, and the contents of the change can be instantaneously grasped. If a detour reference route cannot be found by one candidate input, the same process is repeated to find a detour reference route.
[0066]
FIG. 6 shows a display screen in the case where the detour reference road is superimposed on the screen of the display device 5 on which the initial reference road shown in FIG. 5 is displayed. Here, for the sake of explanation, the detour reference route is shown by a dashed line, but the detour reference route is indicated by a single-dot chain line in yellow. The display may be displayed in a different color and line type from the initial reference road indicated by the dotted line.
[0067]
For example, in the construction of a new building, if the check device 1 is used to three-dimensionally display the current reference route of the wireless line on the display device 5 and the new building and construction equipment are displayed three-dimensionally, It is also possible to determine whether or not a new building, construction equipment, and the like overlap on a reference road of a currently provided wireless line and become an obstacle.
[0068]
【The invention's effect】
According to the present invention, as described above, if there is a building that may become an obstacle on a reference road by displaying the current ground and the building three-dimensionally, the building that becomes an obstacle may become an obstacle 3D display in a different display format, such as by changing the color of a low-impact building, and / or a different display format, such as color-coding a reference road with obstacles on the road with a reference road without obstacles on the road. Since it is displayed in three dimensions, it is possible to see at a glance whether there is an obstacle on the reference road in the current predicted area, what the obstacle is, where it is, how high the obstacle is, etc. Can be determined.
[0069]
In addition, buildings that are displayed as being constructed within the limits of laws and regulations, such as the height at which they can be constructed and the position of the wall surface, are displayed three-dimensionally in different display formats, such as colors or different outline types, depending on the type of the regulations. And / or three-dimensionally display the reference road where the obstacle is on the road in a different display format such as color-coding the reference road where the obstacle is not on the road. Determine at a glance whether the obstacle is likely or unlikely in the future, what the obstacle is and where it is, what the obstacle is, and what laws and regulations are causing the height. be able to.
[0070]
As a result, when establishing a new wireless line, it is not necessary to obtain information on every existing building that may overlap with the reference road and may become an obstacle, and it is not necessary to perform individual checks. Time and labor can be reduced. Also, even if there is a building to be built on the reference road of the new wireless line, there is no need to wait for information to be obtained until the contents of the construction are clearly determined. Since it does not take much time to complete the construction, the construction of the new wireless line can be carried out without delay and without delaying the construction period.
[0071]
Furthermore, even if there are a large number of buildings to be constructed that are duplicated and displayed on the reference road of the newly established wireless line, they are all displayed in different colors according to laws and regulations, so that it takes time, time and effort. It is possible to know the reason why there is a risk that the building may be constructed at a height enough to become an obstacle due to the laws and regulations.
[0072]
In addition, by estimating the contents of the construction to be constructed, which is displayed in duplicate on the reference road, it is not necessary to construct a base station and establish a new radio line. The wireless line will not be interrupted, and therefore the newly installed wireless line will not be interrupted and will not be affected. As a result, there is no need to change the reference road, so assembling and constructing iron poles and branch lines for installing new wireless lines and installing antennas, and removing iron poles, branch lines, antennas, etc. installed earlier Since there is no need to carry out construction work for installing or disposing of a new wireless line, it is possible to obtain a special effect that unnecessary costs are eliminated. Also, since the detour reference route can be searched and displayed, it is possible to prevent the newly established wireless line from being wasted later.
[0073]
Also, when investigating the possibility of radio interference caused by construction work when constructing a new building, etc., there is no need to ask a specialized contractor to perform a check. can do.
