Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an off-site equipment patrol system for preventing out-of-site equipment damage accidents due to excavation work, etc., and more particularly, to improve efficiency of patrol work, grasp equipment state such as deterioration of equipment, and patrol. It is related to the technology effectively applied to the sophistication of.

[0002]

2. Description of the Related Art Off-site equipment patrols, which are carried out to prevent equipment damage accidents caused by external works, are usually carried out with both a road map and a drawing in which equipment location information is written. This work involves a total of two people, one for driving the patrol car and one for navigating while viewing the road map and the drawing in which the equipment position information is written. However, priority is given to cost saving, and the work that should be performed by two people may be performed by one person.

Further, due to the rationalization of the organization and the like, the business offices are integrated, the area for patrol is widened, and it becomes necessary to carry out patrol even in an area where the user is not familiar with. Therefore, the current patrol must simultaneously drive the patrol vehicle and recognize the road and facility positions, stop the vehicle, check the route, and drive.
In addition, operations such as stopping and checking the route are repeated. Therefore, from the viewpoint of work safety and efficiency, improvement of the patrol system is desired.

As a system for recognizing both the road map and the current position of one's own vehicle at the same time, for example, "Journal of the Institute of Electrical Engineers," Vol.115, P416, published by the Institute of Electrical Engineers, June 20, 1995.
~ 419 car navigation system. The schematic configuration of this car navigation system is shown in FIG.
Shown in

Reference numeral 121 is a remote controller, 122 is a GPS (Gl
global Positioning System) antenna (Global Positioning System antenna), 123 is a GPS receiver, 12
4 is a vibration gyro, 125 is an interface circuit, 12
6 is a CD-ROM drive, 127 is a vehicle speed sensor, 12
8 is a VICS receiver, 129 is a processor (CPU,)
Reference numeral 130 is a memory, 131 is a drawing circuit, 132 is a liquid crystal monitor, and 133 is a map CD.

The car navigation system mainly has a function of detecting a position and an interface with a driver as a user, and various functions have been added to the car navigation system to make it easy to use. That is, as shown in FIG. 7, the GPS antenna 122 as a sensor for detecting the automatic position,
The vibration gyro 124 and the vehicle speed sensor 127 are used together, and are composed of a CD-ROM 133 for storing map information, a liquid crystal monitor 122 for displaying a position, a processor (CPU) 129 for signal processing, and a memory 130.

In the car navigation system, on the map previously recorded as latitude / longitude coordinates,
Latitude obtained by Global Positioning System (GPS)
By displaying the position of the car with longitude as the coordinate, it is possible to recognize where the car is located on the road map.

At present, not only GPS but also a method of more accurately obtaining the position of one's own vehicle on a map by using methods such as autonomous driving and map matching have been proposed. In addition, as a system similar to a car navigation system, a location where the positions of a plurality of vehicles obtained by GPS are communicated with each other by using wireless or mobile phones and the positions of the vehicles on the map are grasped by each other or collectively. The system is starting to be used in police stations and taxis.

[0009]

Both of the above systems aim to improve work efficiency by displaying the position of the vehicle on the existing map data. In these systems, a general road map is used as map data, or a map developed exclusively for a system that operates only in a high-speed and large-scale system is used.

Therefore, a simple customizing method for customizing a general road map or the like into map data according to different uses for each user, that is, a simple creation of a map having a function most suitable for the use of the user is desired. ing.

An object of the present invention is to provide an outdoor facility which has a function most suitable for a user's purpose and is capable of performing patrol of outdoor facilities safely and efficiently, while being based on a general-purpose car navigation system. To provide an equipment patrol system.
