Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an area confirmation test system in mobile communication that conducts a confirmation test of whether radio waves from a base station reach all within a service area during construction or maintenance of a mobile communication system.
[0002]
[Prior art]
The confirmation test of whether the radio waves from the base station have reached all within the service area at the time of construction or maintenance of mobile communication systems such as mobile phones and PHS consists of travel map creation and travel test by electric vehicle. Conventionally, the following method has been used.
[0003]
First, as a pre-processing step, purchase a map of the area to be traveled (the range served by the mobile radio base station), transfer the station location to the map from the design drawing, and copy the required number of such maps containing the station The total power area is written on the pasted map, and the driving route is planned on the map where the total power area is written. This planning is done while looking at the road map and taking into account one-way traffic and entry prohibition. After planning, calculate the mileage with a kilvimeter.
[0004]
In this way, the map is cut and pasted to make a single map that can cover the entire area, and a travel map is created on the basis of the route that allows efficient test travel based on experience.
[0005]
Moreover, when actually traveling, the traveling route diagram was brought into the vehicle and a traveling test was performed while viewing it. In this running test, the navigator instructs the next route while checking the position of the vehicle using the car navigation system.
[0006]
[Problems to be solved by the invention]
In the conventional test method, since a map is created (cut and pasted) to planning for each base station, it takes much time and operation. In addition, the cost of paper, copy, and stationery used for the planning of a single station is high, and there is a lot of waste of resources. When planning, it is very inconvenient because it uses a large work space. In addition, storage space is required.
[0007]
Moreover, in the case of re-measurement, there is a need to plan again (about 10%), which cannot be reused, resulting in a loss of operation. Furthermore, since it is a manual operation, there is a possibility that a planning error may occur.
[0008]
An object of the present invention is to provide an area confirmation test system in mobile communication that can eliminate the inconveniences of the prior art and can greatly reduce the travel route map creation time.
[0009]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is , firstly, a personal computer storing map software, base station data input means for displaying a map on the personal computer, mesh dividing means for measurement area, and each mesh. A means to automatically set the intersection closest to the center point as the passing point every time and a means to automatically create a route map with a short mileage passing through all the points in the mesh can be formed and installed in the electric vehicle A portable personal computer for inputting data relating to the route map, and a means for performing an area test to measure the strength of radio waves by traveling according to the travel route diagram displayed on the personal computer; A portable personal computer is equipped with a GPS system position detection and display function, and the vehicle position detected by the GPS system can be detected. It is an gist in that a display means for displaying on the route diagram.
[0010]
According to the first aspect of the present invention, the map is displayed on the personal computer storing the map software and the base station data is input, then the mesh of the measurement area is divided, and the points that pass when traveling for each mesh. Is automatically set, a route map with a short mileage passing through all of the points in the mesh is automatically created, data related to the route map is input to a portable computer, and this portable computer is installed in the electric vehicle. Then, run an area test to measure the strength of radio waves by driving according to the route map displayed on the PC. In this way, planning of the driving route is made using a personal computer, and there is no need to create a map, so direct planning is possible, saving time and minimizing the use of paper, stationery, and copying. Can be suppressed.
[0011]
In addition, the planning by the personal computer eliminates the narrowing down of the work space, the travel route data can be stored in the FD, etc., and it can be used for the data for re-measurement and the data for submission, thereby reducing time loss.
[0012]
In addition, a copy of the original document is not required. Since the map data in the city center is detailed and the road display etc. is accurate, the accuracy during driving is improved.
[0013]
According to this invention of Claim 2, in addition to the said effect | action, it can confirm the next route, confirming the own vehicle position, without using a car navigation system.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail. The present invention is composed of two stages, that is, a travel map creation and a travel test by an electric vehicle, and as shown in FIG. 10, a personal computer 1 for travel map creation and a personal computer 2 that can be carried and carried in an electric vehicle are used. And
[0015]
A personal computer for creating a travel map is preferably a hardware of Pentium (registered trademark) III (memory: 256 MB or more HDD: 10 GB or more).・ M-Nav (Ver2.5) navigation map (1 / 25,000) ・ Raster map (1 / 25,000) ・ Linesman] etc. The original software (Lines Man) is stored. A portable personal computer is a notebook personal computer, and stores the same software as that of the travel diagram creation personal computer.
[0016]
First, start the system of the present invention on a personal computer for creating a travel map, and display a screen for selecting a regional company (as shown in FIG. 1, docomo as a regional company in the example shown in FIG. 1). Next, a branch selection screen is displayed as shown in FIG. 2, and a branch is selected.
[0017]
When a branch is selected in this way, a basic data input screen for creating a travel route is displayed, and base station input (station name, station position, sector tilt angle, etc.) is performed. 3 and 4 show a selection process screen and a base station new registration screen. Since a 1 / 25,000 map centered on the base station registered in this way is displayed, the sector / direction is registered. FIG. 5 shows a sector information input screen. FIG. 6 is a sector information output screen.
[0018]
Next, the planning area (shaded) is meshed. FIG. 7 shows a mesh screen. The mesh size can be arbitrarily set in the range of 1 m to several km, and the size varies depending on the design conditions of the orderer. The reference dimensions are as follows.
・ Case-1 Tokyo Yamanote Line → 300m mesh ・ Case-2 Urban area → 500m mesh ・ Case-3 Plan area appearance → 1km mesh [0019]
In this way, the map is cut with a mesh, and a travel point in the mesh (planning area) is created with the intersection closest to the center point as a passing point. FIG. 8 shows a travel point creation screen in the mesh (planning area).
[0020]
The travel points are connected to complete a travel route as shown in FIG. This automatically sets the points that pass when traveling for each mesh, and automatically creates a route map with a short traveling distance through all the points for each mesh, and uses commercially available high-speed search algorithm software.
[0021]
The created route is stored in the FD and CF and installed in a laptop computer that can be configured and brought into the train, and the navigator supports the next route while viewing the route map displayed on this laptop computer. Do.
[0022]
The notebook personal computer has a GPS function, and the position of the vehicle ascertained by the GPS system is also displayed on the travel route diagram.
[0023]
