| Zusammenfassung: | The invention discloses a coal mine borehole resistivity monitoring receiving antenna, which comprises a signal receiving circuit, a front conditioning circuit, an antenna control circuit and a serial communication circuit, and is characterized in that the output end of the signal receiving circuit is connected with the input end of the front conditioning circuit; the output end of the front conditioning circuit is connected with the input end of the antenna control circuit, and the output end of the antenna control circuit is connected with the input end of the serial communication circuit. By adopting a mode of combining the receiving circuit, the antenna control circuit and the serial communication circuit, the signal receiving precision is ensured not to be influenced by external interference, the signal resolution is improved, and the technical problem that the detected precision is not high due to the fact that a receiving device in the prior art is easily influenced by the external interference is solv |
