the step of receiving a control instruction sent from the outside through a sending device so that the sending device sends an infrared signal to a receiving device corresponding to the sending device according to the control instruction comprises the following steps:
receiving the control instruction through a chip module, so that the chip module respectively sends a clock control signal and a data control signal according to the external control instruction;
receiving the clock control signal through the first infrared sending module, so that the first infrared sending module sends a clock infrared signal to the first infrared receiving module at a first carrier frequency according to the clock control signal;
and receiving the data control signal through the second infrared sending module, so that the second infrared sending module sends a data infrared signal to the second infrared receiving module according to the data control signal and a second carrier frequency.
9. The IIC signal transmission method as claimed in claim 7, wherein the step of receiving the control command issued from the outside through the transmission device is preceded by:
sending a data detection infrared signal to the receiving device by the sending device with a preset data delay time, and sending a clock detection infrared signal to the receiving device by the sending device with a preset clock delay time;
respectively sending a data detection infrared signal and a clock detection infrared signal to the receiving device by the sending device according to corresponding preset data delay time and preset clock delay time;
judging whether the phases of the data detection infrared signal and the clock detection infrared signal are consistent or not through a phase detection module in the receiving device;
if yes, sending a confirmation signal to the sending device, and executing the following steps: receiving a control instruction through a sending device;
if not, adjusting the preset data delay time and the preset clock delay time.
10. A computer-readable storage medium, characterized in that a computer program is stored thereon, which computer program, when being executed by a processor, realizes the steps of the IIC signal transmission method according to any one of claims 7 to 9.
