In general, a manhole is designed to allow an operator to move in or out to inspect, connect, repair, or clean underground water pipes, sewer pipes, wiring, and underground communication cables. The upper part of the manhole obstructs walking or vehicle operation And a manhole cover is installed to prevent a safety accident.

Although manholes installed on the ground such as electricity, communication, gas, and water supply and sewerage are managed by their own management numbers, only the owner or use of the manhole such as waterworks, KEPCO, But the control number of individual manhole is not indicated.

This is because most of the manholes are installed on the roads and are easily broken by people or vehicles.

In addition, since the management number is displayed in most of the manholes, it is necessary to open the manhole cover one by one in order to check it. Therefore, the work efficiency for the worker to open the manhole cover is lowered and the fatigue of the worker is accumulated, There is a problem in that the management department takes a long time to find the manhole to be operated and human and material accidents due to misidentification occur.

In addition, there is a case in which the mark attached with the management number of the manhole is welded to the manhole cover. However, there is a problem that the field work for attaching the mark is difficult and the mark attached is damaged by the vehicle or the pedestrian.

In order to solve such a problem, a manhole cover having a management number indexed to the registration room 20-0244835 has been found, which is a conventional manhole cover which is indexed with a corresponding jurisdiction mark, a use name mark and a parking prohibition mark Wherein at least one or more grooves are formed in parallel on the upper surface of the manhole cover at regular intervals and the management numbers designated in the grooves are indexed with paint to facilitate identification. The position of the manhole and the like are input to a computer or a book, so that an administrator can easily grasp the information, thereby facilitating post-management.

However, since the conventional manhole cover must be manufactured separately, the conventional manhole can not be applied to the existing manhole, characters can not be displayed, and the management number indexed by the paint on the surface of the manhole is peeled off, have.

As another example, an identification table installation structure of a manhole integrated management system as disclosed in Patent Publication No. 10-2010-0005420 has been developed, which is provided with an identification tag installed on a manhole cover and storing a unique number for a manhole, And a terminal for acquiring or updating information on each manhole by wireless or wire communication with the main server, the terminal being connected to the identifier reader, Wherein the identification mark is interposed between an installation member and a transparent protection member which are sequentially fixed and filled in an installation groove formed in an upper surface or a lower surface of a manhole cover, By firmly fixing and fixing the durability with the member, The system can be implemented and utilized in business.

However, in such a conventional art, the mounting hole is provided in the manhole cover for mounting the identification tag on the manhole cover, and the workability is remarkably improved by the installation process for installing the identification mark and the protection member in the installation groove There is a falling problem.

Further, it is troublesome to additionally provide a tag reader, a main server, and a terminal in order to perform wire communication with an ID tag installed on a manhole cover.
