(One embodiment of the present invention)
FIGS. 1 to 4 show a case in which a destination guidance apparatus according to an embodiment of the present invention is used together with a destination guidance method to guide an operator to a utility pole located at a predetermined position in a jurisdiction of a power company. It will be described based on the following. FIG. 1 is an overall block configuration diagram of a destination guidance device according to the present embodiment, and FIG. 2 is a diagram of a reference area mode based on destination information stored in a reference point information storage unit in the destination guidance device shown in FIG. FIG. 3 is a view showing a divided area and a subdivided area based on destination information stored in the reference point information storage unit in the destination guiding apparatus shown in FIG. 1, and FIG. 3 shows an applied operation flowchart.
[0013]
In each of the drawings, the destination guidance device according to the present embodiment stores an input unit 1 for inputting a power pole code for specifying a power pole serving as a travel destination, other operation commands, and various types of destination information regarding the travel destination. A reference point information storage unit 2 for performing a calculation of a latitude and a longitude based on the destination information of the location of the telephone pole specified by the input telephone pole code, and a satellite transmitted by the GPS. A GPS device 4 for specifying a predetermined position on a map based on a time signal and position information, and controlling display on a map specified by the GPS device 4 based on the calculated latitude and longitude of the location of the utility pole. The display control unit 5 performs a display on the power pole of the moving destination point on the map based on the control of the display control unit 5.
[0014]
The reference point information storage unit 2 includes a plurality of management areas 001 obtained by equally dividing predetermined latitudes and longitudes located in the jurisdiction of the electric power company between the management area base lines in the east and west directions and in the north and south directions. ,..., Nnn, and stores information of the reference point A specified by the latitude and longitude at the upper left corner of each. The management areas 001,..., Nnn divide, for example, 37 degrees from latitude 32 ° 40 ′ to latitude 33 ° 20 ′ north on the map shown in FIG. 2A, and 129 ° 45 ′ east to 130 ° 30 east. Is divided into 35 to form a square area of 2 km × 2 km in the first square as shown in FIG. 2 (B).
[0015]
Each of the reference points A1,..., Annnn of the management areas 001,..., Nnn has a latitude of 1′6.67 ″ with respect to a distance 2km of the management areas 001,. Can be calculated in advance because the longitude for the is 1'15 ". For example, the reference point A1 can be sequentially specified as 33 ° 20 ′ north latitude and 129 ° 45 ′ east longitude, and the reference point A12 can be sequentially specified as 33 ° 18′55.33 ″ north latitude and 129 ° 46′15 ″ east longitude.
[0016]
Next, a worker guiding operation of the destination guiding device according to the present embodiment based on the above configuration will be described.
First, the operator inputs, for example, a telephone pole code “001 555” as the destination information of the moving destination point from the input unit 1 (step 1). This telephone pole code “001s 555” indicates the code of the management area 001,..., Nnn where the first to third digits are the reference area, and the upper four digits are the divided areas A, I, C, D,. , And the lower three digits indicate the pole number. The utility pole number is assigned to the utility pole arranged in the section area.
[0017]
The utility pole code “001s555” input from the input unit 1 is input to the destination information calculation unit 3, and the destination information calculation unit 3 specifies the management area 001 based on the utility pole code “001s555”. Then, the latitude and longitude at the reference point A1 of the management area 001 are read from the reference point information storage unit 2 (step 2). For the reference points A1,..., Annnn, the latitude and longitude values calculated in advance in association with the management areas 001,. The latitude and longitude of the reference points A1,..., Annnn are determined in advance by specifying one specific reference point (for example, A1), and using the specified one reference point A1 as a reference for each operation. Points A2,..., Annnn can also be obtained by calculation.
[0018]
The destination information calculation unit 3 calculates the division point B of the division area based on the read reference point A1, for example, at 33 ° 25'33.33 "N and 130 ° 8'45" E. As shown in FIG. 3A, the relative positional relationship between the reference point A1 and the segment point B is 33.34 "in latitude and 37.5" in longitude. Is calculated as follows (step 3).
[0019]
Regarding latitude,
33 ° 25'33.33 "-33.34" N = 33 ° 24'59.99 "N
As for longitude,
130 ° 8'45.00 ”+37.50” = 130 ° 9'22.50 ”East
It becomes.
[0020]
Further, the destination information calculation unit 3 subdivides the subdivision area including the position of the telephone pole number 555 based on the latitude 33 ° 24′59.99 ″ N and the longitude 130 ° 9′22.50 ″ E of the division point B. The latitude and longitude of the point C are calculated (step 4). As shown in FIG. 3 (B), the subdivision area is divided into 10 equal divisions of the division areas A, B, C, D,... In the respective directions of latitude and longitude, and the first cell is a square area of 50 m × 50 m. Since the relative positional relationship between the division point B and the subdivision point C has a difference of 8.35 "in latitude and 9.40" in longitude, the following calculation is performed from this difference and the division point B. I do.
[0021]
Regarding latitude,
33 ° 24'59.99 ”N-8.35” N = 33 ° 24'51.64 ”N
As for longitude,
130 ° 9′22.50 ″ +9.40 ″ = 130 ° 9′31.90 ″ East
Here, the destination information calculation unit 3 determines whether or not this subdivided area is the smallest subdivided area including the telephone pole number 555 (step 5). If it is determined in step 5 that this is the smallest subdivision area, the center point of this subdivision area is calculated based on the latitude and longitude of the subdivision point C of this subdivision area (step 6).
[0022]
Regarding latitude,
33 ° 24'51.64 "-0.83" = 33 ° 24'50.81 "N
As for longitude,
130 ° 9′31.90 ″ +0.94 ″ = 130 ° 9′32.84 ″ East
It becomes.
[0023]
In this way, as shown in FIG. 3 (C), the latitude and longitude information of the center point in the subdivision region calculated by the destination information calculation unit 3 is output to the display control unit 5, and this display control unit 5 The center point of the subdivision area including the telephone pole at the destination point is displayed on the display screen of the display unit 6 in relation to the current position on the map specified by the device 4 (step 7).
[0024]
If it is determined in step 5 that the subdivision area is not the minimum division area including the telephone pole number 555, the process returns to step 4 again to calculate the latitude and longitude of the subdivision point C in the subdivision area. Become.
[0025]
From the relationship between the center point of the subdivision area displayed on the display unit 6 and the current position of the operator, the worker can be guided smoothly and reliably into the subdivision area. The worker guided to the center point of this subdivision area easily identifies the target telephone pole 555 within a radius of 36 m from the center by observing the entire circumference while standing at the center point shown in FIG. can do.
[0026]
In the above-described embodiment, the configuration is such that the center point of the subdivision region is displayed to guide the worker, but the configuration may be such that the worker is guided to the worker division point of the subdivision region. In this case, the worker can confirm the telephone pole by standing on the subdivision point C and observing 90 ° from the south direction to the east direction.
[0027]
Also, in the above embodiment, the first four digits of the utility pole code are the codes of the divided areas A, A, C, D,. ..,...,... Are divided into 16 divided areas in 4 × 4 cells, but the first four digits of the telephone pole code are a single cell. In this case, it is also possible to set the divided area Y, and to set the divided area C, C, H, and F when the cell is a 2 × 2 square.
[0028]
For example, in a case where the management area 001,..., Nnn specified by the first three digits of the telephone pole code is an area of 2 km × 2 km, the divided areas A, A, C, D,. ... are each a 500 m × 500 m area, and the first cell of this subdivided area is specified as a 50 m × 50 m area, whereas the divided areas c, b, f, f are each a 1 km × 1 km area. The first cell of this subdivision value is specified as an area of 100 m × 100 m. Further, since the divided area Y is an area of 2 km × 2 km, the first cell of this subdivided area is specified as an area of 200 m × 200 m.
As described above, since the divided area specified by the first four digits is divided into different areas, the area can be divided and displayed according to the degree of density of buildings and houses in the area.
[0029]
Further, in the above-described embodiment, it is configured to determine whether or not the area is the smallest subdivision area in step 5, but the reference point of the management area is read, the latitude and longitude of the division area are calculated, and the latitude and longitude of the subdivision area May be recognized, and the operator may be guided to the final predetermined area or predetermined point based on the recognition result.
[0030]
In the above-described embodiment, the GPS device 4 is configured as an integrated device. However, the GPS device 4 is configured as a navigation system 40 as shown in FIG. Can be integrated by transmitting and receiving signals by infrared transmission. In this case, the navigation system 40 is provided with an infrared processing receiver 40a, and the main part of the destination guidance device is provided with an infrared processing transmitter 40b. The infrared processing receiver 40a and the infrared processing transmitter 40b are connected to each other. Data relating to the center information of the subdivided area is input / output in the same signal format as the GPS signal. The data, for example, the center information of the subdivided area is input to the GPS calculation processing section 42 via the infrared processing reception section 40a, and the GPS calculation processing section 42 receives the GPS signal input from the GPS reception section 41 and the subsection area. A map can be displayed on the display unit 44 from the center information.
[0031]
As described above, the destination guidance device can be easily configured using the function of the existing navigation system 40 mounted on the vehicle, for example.
Further, in the above-described embodiment, each worker calculates and displays the information of the moving destination point. However, when a plurality of workers move to the same moving destination point from different points, the plurality of moving destination points are calculated. At least one of the workers calculates the information on the destination point of travel, transmits the information of the destination point of travel to other workers by communication means, and displays the information on the display unit of each worker based on the transmitted information. It can also be done.
[0032]
Further, in the above-described embodiment, the configuration is such that the latitude B and the longitude in the upper left corner of the management area, the division area, and the subdivision area are specified as the reference point A, the division point B, and the subdivision point C. Arbitrary points determined based on the lower left, upper right, lower right, and other predetermined regularities of the area or the subdivision area can be specified as the reference point A, the division point B, and the subdivision point C.
[0033]
Furthermore, in each of the above embodiments, after the worker is guided to the subdivision area, the surroundings are observed to confirm the object at the travel destination point. It is also possible to adopt a configuration in which a boundary with another adjacent subdivided region is calculated, and this boundary is visually or audibly notified on a display device or the like, and each of the divided regions at the current location is reliably specified.
[0034]
As described above, according to the present invention, the reference area having the reference point specified by the latitude and longitude at the specific corner of the square area is sequentially divided based on the predetermined regularity. When destination information including each code for identifying the reference region, the divided region and the telephone pole is input, the latitude and longitude of the moving destination point specified by the destination information are determined by the latitude and longitude. Since the calculation is performed sequentially from the points and the guide unit guides the worker to the moving destination based on the calculation result, it is necessary to prepare in advance information on the individual latitude and longitude of each pole at each moving destination. In addition, there is an effect that a destination point of movement is determined with an extremely small amount of information of latitude and longitude, and an operator can be guided in conjunction with GPS.
Further, in the present invention, since the worker is guided to the center position of the subdivision area including the travel destination point, there is an effect that the target of the travel destination point can be easily recognized in the subdivision area. .
Further, in the present invention, since the boundary of the subdivision area including the travel destination point is notified, the worker guided to the subdivision area surely reaches the travel destination point without departing from this range. It has the effect of being able to.
