[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patrol terminal device which is used, for example, for new installation, maintenance and management of power transmission and distribution equipment, management of information on buildings in an urban area, and management of customers in sales. .

[0002]

2. Description of the Related Art Conventionally, when a power company performs route planning, maintenance and management of a new power transmission and distribution facility, a patrol patrol carries a map printed on paper and is described on the map. The contents and the local situation are compared visually. They also conduct surveys or take pictures at the site, bring them home, and analyze them with in-house experts. Based on the results, a new route for transmission and distribution equipment is set and equipment is designed. In the case of maintenance and management, equipment change design and maintenance and management planning are performed. In addition, the necessity of patrol of various facilities and houses is not limited to the above-mentioned power transmission and distribution facilities, but is also necessary for new road plans and maintenance and management, railway and subway new designs and maintenance and management. However, in this case, too, we went around the site based on the map,
It is a conventional general method to bring back and use observation information such as surveying. In addition, they rely on city maps when traveling around the city for sales of general products.

[0003]

Since the conventional construction, maintenance and management of power transmission and distribution equipment has been carried out by relying on maps, it is difficult to identify and confirm the exact current position of patrol members on the map. It is. Therefore, in order to know the exact position, surveying must always be performed. In addition, since the planning and design of the equipment are performed on the desk in the company, it is not possible to accurately grasp how the planned and designed matches the site. For example, if a new route is set on the desktop based on a map or a local photo,
It is not possible to set accurate information from the viewpoint of integration with the local environment and landscape. Also, in maintenance and management, it is difficult to formulate a plan that incorporates detailed local information, such as tree growth and changes in river paths.

[0004] This also poses a similar problem in the planning and maintenance and management of roads, and in the maintenance and management of railways and subways. In addition, in the patrol of the city area for the purpose of general business activities, etc., when relying only on the city area map,
It is difficult to find or confirm the current position on a map, and especially when the situation changes due to redevelopment of the city area, etc., it becomes impossible to accurately grasp the patrol position. Also, on the map alone, it is not possible to immediately know the information on the area or building, or detailed data on the market or customers, and it is not necessary to carry information separately for maps by recording information necessary for sales in a notebook, etc. Will not be.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and when traveling for the above various purposes, the current position can be accurately known on a map, and various kinds of local information can be obtained. It is an object of the present invention to provide a patrol terminal device that can be checked on the spot and can be corrected.

When the mode is switched to the PS reception mode, the GPS reception is performed based on radio waves from a plurality of GPS satellites received by the GPS antenna 7.
The current position is calculated in the receiving device 6. The position measurement data calculated by the GPS receiver 6 is transferred from the interface 5 via the bus line 100 to the RAM 4 or another buffer memory (not shown) provided in the control means (system controller) 1 and stored therein. Is done. When the GPS reception mode is set and the control program is executed based on this setting, the map table of contents data transferred from the map management table Ta to the RAM 4 is referred to based on the position measurement data from the GPS receiver 6. The map data including the position coordinates based on the position measurement data, that is, the current position, is read from the map data storage unit Da in the map memory 13. The read map data is stored in the buffer memory 17 in the display means 15 via the bus line 100. Then, the map data in the buffer memory 17 is processed by the image processing unit 16, and the map is displayed on the display screen 18 a of the display device 18.

At this time, the highest scale map (for example, 1/1000) including the current position is displayed on the display screen 18a. When a map with a lower scale (for example, 1/500 or 1/100) is required by looking at the display screen 18a, an instruction to change the scale is input by one of the push button switches 11a. By this scale change instruction operation, the scale data transferred from the map management table Ta to the RAM 4 is referred to, and the lower scale map data including the coordinate position (current position) based on the position measurement data is stored in the map data storage unit Da. It is called and transferred to the buffer memory 17. The position measurement data calculated by the GPS receiver 6 is also transferred to the buffer memory 17 and added to the map data. Then, as shown in FIG. 4A, a map (i) of a predetermined scale representing the terrain in a plane and a mark M indicating the current position are displayed on the screen 18a.

Next, one of the push button switches 11a or the pen input device 11b is operated to select the display of data based on the new design picture of the power transmission and distribution equipment. In this selection operation, the information management table Tb of the additional information memory 14

By selecting using b, it is possible to change or correct the display of the scenery and the tower that appear on the display screen 18a. This modification includes, for example, changing the shape of the mountain, the height of the tree, and the position of the tower based on the actual landscape. This correction can be made only for the additional information, or the map itself shown in (i) can be corrected. As a specific data correction method,
For example, in the horizontal line visual landscape screen shown in FIG.
If it is necessary to change the installation location of the tower,
First, the display on the screen 18a is returned to a screen showing the planar terrain map (i) as shown in FIG. 4A and additional information such as a transmission line route on the map (i). Change the position and transmission line route. After this correction, the horizon visual landscape screen shown in FIG. 4 (B) is set, and the relationship with the landscape at the correction location is confirmed.

After the additional information relating to the landscape is corrected according to the above procedure, the pen input device 11b or the like instructs storage of the corrected data. According to this instruction, the corrected data, that is, the corrected data obtained by correcting the landscape image shown in FIG. 4B is stored in the corrected data storage unit Dc in the additional information memory 14 via the bus line 100. Alternatively, the data may be updated such that the data on the landscape screen in the information data storage unit Db is replaced with the data after the correction. The revised or updated data can be taken back to the company and the database of the main computer can be modified to make the new database of power transmission and distribution equipment in the inspected area more realistic, Accurate data can be used for final planning and civil engineering design.

The camera 1 is mounted on the housing 31 of the patrol terminal device.
When the camera 9 is connected, a still picture can be taken at the inspection position, and this can be displayed on the window Wb on the display screen 18a as shown in FIG. By correcting the landscape image with reference to this photograph, the image can be easily corrected. Alternatively, the image of the still picture may be superimposed on the graphic image of the scenery shown in FIG. 4B and displayed, and the image of the graphic picture may be corrected by tracing the image of the still picture. Further, the corrected image data and the still picture image displayed in window Wb may be stored together in corrected data storage unit Dc.

Alternatively, the same map and additional information can be displayed on each screen at the same scale or at different scales. Thus, a map of a large area (high scale) can be displayed on one screen, and a low scale map with a part thereof enlarged on the other screen can be compared. Further, the additional information can be displayed on both screens or on one screen.

When used for patrol of the power transmission and distribution equipment shown in FIG. 4, one screen displays a map of the planar terrain (FIG. 4).
(A) is displayed, and then, for example, the path of the transmission line and the position of the tower are corrected or the data of the additional information on the arrangement of trees and buildings is corrected, and at the same time, the data correction location is displayed on the other screen as a horizon. (See FIG. 4B) can be graphically displayed.
Thereby, the correction of the additional information and the confirmation of the landscape on the map of the planar terrain can be performed at the same time, and the correction of the data such as the additional information becomes easy. At this time, by changing the scale of the planar map and the scale of the landscape display to, for example, (1/100) vs. (1/500), a limited area is enlarged and data is corrected, and the landscape is broadly viewed. Can be confirmed.

Since the inspection terminal is a small portable device, it is preferable to use an 8-inch, 6-inch or 5-inch type color liquid crystal display device as the display device. In the patrol terminal device, a map having a low scale is used for the characteristics of its use ((1/500) to (1/10)).
Often a scale of 0) is used, and in some cases even smaller scale maps are used. GB which receives radio waves from GBS satellites as position measurement means
When S receiver is used, the position measurement accuracy is about 1cm
Is possible with high accuracy. Therefore, the resolution of the map when using the color liquid crystal display device is (1/10)
It is desired that an order of several cm can be secured on a scale of about 0).

FIG. 9 shows the pixel size of the color liquid crystal display device on the vertical axis and the distance on the map (on the screen) on the horizontal axis. For example, as shown by the line α, when the scale of the map is 1/100 and the pixel size is 0.1 mm or less, the distance on the displayed map is several cm.
Can be confirmed in the order of In consideration of the reduced scale of the map and the receiving accuracy of the GBS receiver, it is preferable to use a pixel size of the liquid crystal display device of 0.1 mm or less, which is sufficient on the displayed map. High resolution can be obtained. Note that the pixel size of the color liquid crystal display device was determined to be 0.12 based on ease of operation and visibility in a normal use environment.
It is preferably 5 mm or less, and more preferably 0.1 mm or less. In each of the above embodiments,
The correction of data is performed for each data related to additional information and / or map. Here, “correction” means not only correction of data contents, but also addition or deletion of data, and furthermore, addition of data. And also includes a case where additional information is newly added without any additional information.
