The invention provides a low-frequent wireless bidirectional ground penetrating communication device. The low-frequent wireless bidirectional ground penetrating communication device comprises a voice input module, a voice output module, a signal processing module, a signal input module and a signal output module which are connected with one another. The signal processing module comprising a frequency boosting and lowering control unit, the frequency of a signal received by the voice input module is lowered through the frequency boosting and lowering control unit, then the signal is transmitted to the signal output module to form a signal transmission mode; the frequency of the signal received by the signal input module is boosted up through the frequency boosting and lowering control unit, and then the signal is transmitted to the voice output module to form a signal receiving mode. The low-frequent wireless bidirectional ground penetrating communication device and a method thereof have the advantages that voice communication at a low safe power is achieved in a down hole environment or in an environment with combustible gases, bidirectional voice and data communication are achieved, and delay time is short. Further, the low-frequent wireless bidirectional ground penetrating communication device and the method thereof are suitable for emergency communications in disaster relief and rescue completely.
Description
technical field [0001] The invention relates to a low-frequency wireless two-way through-the-ground communication device, and also relates to a low-frequency wireless two-way through-the-ground communication method. Background technique [0002] At present, in environments such as underground mines, industrial structures and commercial buildings, the transmission of electromagnetic energy is blocked or limited by media or obstacles, and communication is realized through hard lines such as telephone lines. However, when a disaster occurs, the roadway is blocked, the power is interrupted, and the hard line is damaged, how to establish an effective wireless communication between the disaster area under the mine and the mine becomes a problem. [0003] However, the transmission of the signal through the ground has brought other problems. The power of the equipment that can be safely used in the mine is very limited. Because of the existence of dangerous flammable gases, the ener...
