Description

Underground joint zone remote monitoring system

The present invention relates to a remote monitoring of an underground common area, and more specifically, the status and alarm of a fire receiving panel in a specific place that requires remote monitoring as well as an underground common area such as a communication or power outlet, monitoring the water level of a collection well, and monitoring the pump and fan. It relates to a remote monitoring system for underground communal zones to remotely monitor various signals and video signals such as start/stop status, CCTV video, etc., control and restore as necessary, and to make history management D/B.

In general, an underground common area refers to a common area, communication area, and power area for collectively accommodating electric wires, gas, and pipes used for heating and cooling for electric power communication, and is 1.8m wide and high, constructed to allow human inspection or repair. It refers to an underground facility with a length of 2m and 50m or more (500m or more in case of electric power and communication business).

The purpose of constructing an underground communal zone is to improve urban aesthetics, preserve road structures, and facilitate traffic communication by jointly accommodating supply facilities such as electricity, gas, and water, communication facilities, and sewage facilities.

However, since the underground common zone plays an important role in the operation of the city and is located in a poor environment underground, there is a problem that a lot of manpower and budget are required for the maintenance and management of the underground common zone.

Therefore, a variety of systems have been developed to efficiently manage underground public tracts.

First, in order to systematically manage information on various facilities (water and sewage, communication cables, power lines, water pumps, ventilators, etc.) inside the underground common zone in operating and managing the underground common zone, and to obtain accurate location information for the various facilities An underground common zone management system based on Geographic Information Systems (GIS) was developed.

In addition, in order to monitor the situation inside the underground cavity, after installing various sensors inside the underground cavity, an underground cavity monitoring system was developed that can check the alarms transmitted from the sensors in real time.

However, in the case of the above system, the alarm transmitted from the sensor installed inside the underground cavity is located deep underground (more than 30m), and there are many cases of malfunction due to the poor location environment of the underground cavity with a length of several hundred to tens of kilometers. Therefore, it is difficult for the manager to make an accurate judgment on the alarm occurrence situation, and serious damage occurs if the alarm occurrence situation is misjudged.

In addition, some underground cavities monitor the underground cavities using cameras after installing cameras at important points inside, but there is a problem that it is difficult to visually monitor the entire underground cavities since monitoring is possible only in a limited range.
