Design of mine-used intrinsically safe wireless through-the-earth communication system

  • The paper introduced structure and key technologies of mine-used intrinsically safe wireless through-the-earth communication system,and analyzed working principle of the system. The system uses low-frequency electromagnetic radiation technology, digital communication technology and intrinsically safe power supply technology, which has characteristics of smaller volume, lighter weight and easy operation. The test results of prototype show that the system has realized two-way through-the-earth communication for 50 m with communication rate of about 150 bit/s and bit error rate of no larger than 0.2 %, and has a certain practical value
