The present invention relates to a navigation for guiding facilities buried underground,

More specifically, the database of underground buried materials, such as optical cables, water and sewage pipes, and city gas pipes buried underground, which are invisible to the naked eye, are databased and periodically updated to find the underground buried materials accurately in a short time. The present invention relates to a navigation system for guiding underground burial to prevent damage to dangerous materials in the underground burial.

In modern life, navigation is becoming a necessity for beginners even if they are novice drivers or experienced drivers, and the size, information, and functions of navigation are diversified as the number of users increases.

Navigation is largely classified into CNS type navigation and PDA type navigation according to shape. CNS type navigation is usually composed of 7-inch TV type LCD monitor and navigation body. It also serves as my information terminal, and depending on how it is mounted on the car, it is divided into an indesh type and an on-dash type (mounted type), and according to the electronic map storage method, CD type, DVD type, HDD type, flash memory type Compared to PDA-type navigation, the monitor is larger and has AUDIO and TV reception functions.

On the other hand, the PDA type navigation system uses a well-known PDA on the market, but it is equipped with automatic navigation software and an electronic map. Unlike the fixed CNS type navigation system that can be used only in the car, it is very easy to use map and software upgrades through the Internet. In addition, there is an advantage that the PDA can be used for purposes other than navigation, and PDA users can use the PDA as a navigation device by purchasing an automatic navigation KIT (software + electronic map + GPS antenna) suitable for them.

In addition, the IDIO navigation is a navigation that implements the IDIO service provided by MBC FM as well as the basic navigation functions with the built-in IDIO receiver chip or receiver, and the real-time traffic information is displayed on the electronic map in various distinct colors. You can go back and avoid it, use the dynamic routing function to guide you to the fastest route that does not block the way to your destination, and it is the next generation navigation that shows real-time traffic information and provides the best route when needed. The cost of IDIO receiver is higher than general navigation, but it can be called economical navigation because it can use information anytime and anywhere without additional communication fee and usage fee, and it can check weather, securities, and news information.

In general, GPS or navigation guided the location of local buildings or roads on the ground easily.In the case of underground facilities, the underground facilities were used only if necessary with the information of construction drawings that were initially used to bury underground facilities. Has been renovating, roads or construction work.

However, in general, when laying underground facilities, it is necessary to bury them according to the construction drawings.However, the location of the installation varies according to the situation of the site, and in some cases, the underground facilities that are in the same place by reconstruction or restoration are different. Most of them differed from the locations shown in the original construction drawings by being moved to the site. For this reason, there was a problem that large accidents are often caused by erroneously locating and destroying underground facilities such as optical cables, water and sewage, and city gas during road construction or construction work.

Accordingly, the present invention has been made to solve the above problems,

Its purpose is to provide a reliable guide to underground sites by periodically updating the information of underground facilities to ensure the efficient management of underground facilities such as optical cables, water supply and sewage, and city gas.

In order to achieve the above object, the navigation for guiding underground buried material according to the present invention,

A search unit where previously stored data is searched by place name, and a current position detection unit that enables the user to detect the current location of the user for moving to the location searched by the search unit, and an underground coordinate memory unit and a prefecture where the underground facility coordinate information is stored. A navigation unit for navigating the route from the location to the target coordinates and allowing the directions to the ground, and a map coordinate storage unit for storing map information of the ground corresponding to the underground facility coordinates so as to move through the ground with the underground facility coordinates and the map coordinates. And a display unit for displaying the target coordinates retrieved from the storage unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a chart showing the configuration of the navigation to guide the underground buried material according to the present invention, Figure 2 is a flow chart showing a navigation to guide the underground buried material of the present invention.

As shown in Figure 1 to 2, the navigation for guiding underground buried material according to the present invention,

The search unit 110 and the current location detection unit 120 and underground facility coordinate information that allow the user to detect the user's current location to move to the location searched by the search unit 110. Underground coordinate memory unit 130 is stored and the navigation unit 170 and the underground facility coordinates to navigate the path to the ground by searching the path to the target coordinates 150 from the current location underground facilities to move through the ground And a display unit 160 for displaying the target coordinates 150 retrieved from the map coordinate storage unit 140 and the map coordinate storage unit 140 storing ground map information corresponding to the coordinates.

As described above, the navigation 100 for guiding the present inventors underground works according to the operating state,

In order to receive the accurate location guidance of underground facilities, the construction drawings and construction plans of each city, province, and ward offices are checked, and the data of underground facilities are accurately stored and stored in the underground coordinate storage unit 130 with these data. The map coordinate memory 140 is stored together with the navigation 100 so that it can be found, and periodically updated to store additional information and situations in the navigation 100.

In addition, when the user searches for the desired underground buried material by the place name or underground buried name through the underground coordinate storage unit 130 and the search unit 110 previously stored in the navigation 100, the user can accurately know the location. Coordinates are received from the map coordinate storage unit 140 of the ground formed in the same space as the searched underground burial, in order to find the map coordinate storage unit 140, the current position of the user is given priority through the current position detection unit 120. If the current position is identified as described above, the target coordinates are searched through the navigation unit 170 and the map coordinate storage unit 140 that search the route from the current position to the target coordinates 150 to enable the road guidance to the ground. The location of the underground buried, which is 150, is displayed by the display unit 160 to utilize the navigation 100.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention may be made by those skilled in the art within the above technical scope.

For efficient management of underground facilities such as optical cables, water supply and sewage, and city gas, database information of underground facilities is periodically updated to find underground installations accurately in a short time. It has the effect of use to prevent it.
