Patent ID: 8810072

Claim:
A data transmission method used in a high-power induction-type power supply system consisting of a supplying-end module and a receiving-end module, comprising the steps of: (a) standby time is up, start to transmit a sensing signal; (b) transmit a predetermined main operation frequency to a register; (c) coil voltage detection circuit that is electrically connected to the supplying-end microprocessor of the supplying-end module starts up ADC (analog-to-digital converter) mode; (d) start to output system defined maximum operating frequency to the power driver that is electrically connected to the supplying-end microprocessor; (e) lower the operating frequency; (f) determine whether or not the current operating frequency is equal to the set value of the main operating frequency, and then return to step (e) when negative, or proceed to step (g) when positive; (g) end frequency modulation output, start to sense signal; (h) check whether or not the signal analysis circuit receives a data signal, and then proceed to step (i) when positive, or step (j) when negative; (i) data code inspection software checks the data code to be recognizable or not, and then provide power supply to the receiving-end module when positive, or proceed to step (i) when negative; (j) no data is sensed, the coil voltage detection circuit starts up the ADC (analog-to-digital converter) for data conversion; (k) the sensing signal is ended; turn off the output to the supplying-end module; (l) use the ADC (analog-to-digital converter) data of the coil voltage detection circuit to set the operating frequency and the adjust the output power of the sensing signal; and (m) enter the standby mode, and start to count time until next startup.
