Abstract
The present invention relates to a wireless communication device inside a manhole, comprising: a communication terminal installed inside a manhole; and an antenna extension cable connected to the communication terminal, wherein the antenna extension cable is electrically connected to a manhole cover of a conductive material which acts as an antenna so as to deliver a signal received from the manhole cover of a conductive material to the communication terminal. The wireless communication device inside a manhole is capable of delivering information regarding the inside of the manhole (equipment inspection, leakage check, etc.) to the outside without the manhole cover being opened. As such, it is possible to resolve traffic congestion caused by manhole check; control facilities inside the manhole without opening the manhole cover; by delivering opening and closing information of the manhole cover, prevent theft of the manhole and obviate safety accidents caused by the opening of the manhole cover; and prevent manhole worker safety accidents by monitoring the working environment during manhole work.
