Abstract
An electrode-type near-bit wireless short-distance transmission modulation method includes the steps of by a near-bit measuring tool, measuring parameters, and acquiring parameter information, and packing the parameter information into a data packet, and transmitting the data packet to a transmission processor part; by the transmission processor part, performing binary frequency shift keying modulation on the data packet, and according to a set transmission power and driving source power, passing the modulated data packet through an amplifying circuit and a driving circuit, and then loading the modulated data packet to positive and negative electrodes of a transmitter; and by the positive and negative electrodes of the transmitter, transmitting the modulated data packet passed through the amplifying circuit and the driving circuit to a receiver, so as to realize electrode-type wireless short-distance transmission modulation.
