Problems solved by technology

When conventional wired communication facilities are damaged in mine disasters, it often causes paralysis of communication between the underground and the ground rescue center and surrounding areas; even the "penetrating" communication system using radio electromagnetic wave radiation technology is also affected by the underground environment and electromagnetic wave antenna technology. The impact of the bottleneck, at present, its practical application is only in the "downlink" working state (only the ground sends signals to the underground), it is difficult to achieve "uplink", that is, underground mine personnel send information to the ground rescue and disaster relief command center
Therefore, the ground ambulance personnel can not carry out accurate understanding to the information of underground trapped personnel and dangerous situation, and this has caused great difficulty to rescue work

Abstract

A grounding two-way digital information communication device utilizing ground electric field detection technology comprises an underground device and a ground device. The underground device is composed of an underground communication device and an underground electric dipole moment transmitting / receiving antenna which are electrically interconnected. The underground communication device is arranged in an underground mine refuge chamber or a tunnel and the underground electric dipole moment transmitting / receiving antenna is buried in an underground mine or a tunnel geologic body. The geologic bodies of the underground mine or the tunnel are semi-conductors. The space between the underground device and the ground device is formed to be a geologic body 'channel' for digital communication. The ground device is composed of a ground communication device and a ground electric dipole moment transmitting / receiving antenna which are electrically interconnected. The ground communication device is installed on the ground and the ground electric dipole moment transmitting / receiving antenna is buried in the shallow ground. According to the grounding two-way digital information communication device utilizing ground electric field detection technology, functions of the two-way remote communication and the remote two-way remote control and metering in the ground half-space and water can be achieved.

Description

technical field [0001] The invention relates to a ground-penetrating two-way digital information communication device using the ground electric field detection technology, especially suitable for emergency "ground-penetrating" digital and information communication in the event of a "mine disaster" accident, and at the same time can realize underground half-space and lakes and oceans Two-way communication and remote control telemetry functions in the wireless remote. Background technique [0002] When "mining disasters" (especially coal mines) occur, some survivors are often trapped underground. When conventional wired communication facilities are damaged in mine disasters, it often causes paralysis of communication between the underground and the ground rescue center and surrounding areas; even the "penetrating" communication system using radio electromagnetic wave radiation technology is also affected by the underground environment and electromagnetic wave antenna technolog...
