Description

TECHNICAL FIELD [0001] The present invention relates to a railway monitoring system and a monitoring method using a sensor,

The present invention relates to a railway monitoring system and method using a sensor, and more particularly, to a railway monitoring system and method using a sensor, in which, when a sensor unit installed on a handrail outputs an arbitrary signal, a peripheral image of a sensor unit captured by the camera unit is analyzed, And more particularly, to a railway monitoring system and method using a sensor that can be quickly monitored.

Generally, a railing is a structure that is stood at a certain height on the edge of a stair, a bridge, or a floor, and is installed to prevent a person from falling or to be visually appealing.

Most of these railing are made of simple materials such as steel, wood, tempered glass, etc., so that the children can fall into the gap of the railing, and when the height of the railing is low, An accident may occur.

In particular, even adults who are well aware of the danger, there are people who try to use this point, and the bridge railing of the Han River is a dangerous place, This happens a lot.

For example, 1,301 people have attempted to transport on the Hangang Bridge over the last five years. Of these, only 108 on the Mapo Grand Bridge, 48 people have been killed, and the number of cases of insecure and unstable psychological state and life is increasing.

Conventionally, several CCTVs are installed along the extended longitudinal direction of the bridge to prevent the transmission of such a bridge railing, and the manager monitors the images photographed on the people located on the bridge, and identifies safety accidents A management system in which measures are taken by a rescue team or a staff member of the system is used.

However, in the conventional management system, there is a possibility that the safety accident detection is missed because the manager monitors the images photographed by several CCTVs and confirms the movement of the people located in the entire bridge, As the number of bridges to be increased or the longer length of each bridge is increased, CCTV installed increases, and as a result, video information to be monitored is increased, and the labor cost of the monitoring and monitoring personnel is excessively increased.

Also, even if the monitoring supervisor identifies the trusting agent and the trustee, the time elapses while communicating with the rescue team or the staff member in order to inform the personnel of the telephone conversation. As the contents of the incident are transmitted only by voice, In the case of the accident, only the summarized accident contents are reported to the accident site, and there is a problem that it is restricted to receive the contents of the change of the position of the trustee or the trustee according to the passage of time.
