Based on the above-mentioned embodiment of the control method, a flow chart of a second embodiment of the control method of the present invention is provided, and the step of determining the switching driving command according to the input switching signal includes:

step S11, selecting input driving information corresponding to the rate control instruction from a preset modulation table based on the rate control instruction in the input conversion signal;

Step S12, after the first driving unit and the second driving unit are driven based on the input driving information, feedback rate information is obtained, and a rate difference value between the input driving information and the feedback rate information is determined;

Step S13, if the rate difference value is smaller than or equal to a preset difference threshold value, triggering a preset output instruction based on the input driving information, and taking the output instruction as a conversion driving instruction;

In this embodiment, when determining the conversion driving instruction, it is necessary to preferentially select the input driving information corresponding to the rate control instruction in the preset modulation table based on the rate control instruction in the input conversion signal, where the required rate may be determined based on the input conversion signal, and then the required rate is used as the rate control instruction, where the rate control instruction is the rate required by the input conversion signal, and may be input by a user or be a direct default value.

At this time, after the first driving unit and the second driving unit are driven by the input driving information, the feedback rate information at this time is obtained based on the feedback detection circuit, so as to determine a rate difference value between the input driving information and the feedback rate information, and then, the subsequent targeted control is performed based on the rate difference value, where the rate difference value is a difference value between the rate values of the two information. Because the delay device is designed in the hardware design, the information is not output, the follow-up control can be performed, when the speed difference value is smaller than or equal to a preset difference threshold value, the preset output instruction is triggered based on the input driving information, the output instruction is used as a conversion driving instruction, the difference threshold value is defined value, the setting can be performed according to different environments, the output instruction is the instruction of driving the driving unit by the input driving information, the output signal speed accuracy can be further ensured because a certain error exists, and meanwhile, the speed is controlled, so that the functionality of the optical module is ensured.

That is, at this time, the adjustment is performed based on the relation table between the historical theoretical rate and the actual rate, so that different devices can be adjusted in a targeted manner (the internal influences of the devices are different, and the modulation table cannot be directly used in the same way). And updating the feedback rate information by a third feedback rate, and executing the step of determining the rate difference value between the input driving information and the feedback rate information. And further, adjustment aiming at different situations can be realized, and the functionality of the optical module in different scenes is improved.

In this embodiment, when there is no history adjustment data table, since the second driving unit 42 further includes the first secondary selector and the second secondary selector, further, precise adjustment can be achieved, for example, the adjustment interval can be accurate to 100M, further, the first secondary selector and the second secondary selector can be selected for adjustment. At this time, it is determined that the rate difference value generates a preset high-precision rate driving instruction, that is, an instruction for determining that the rate difference value needs to control the first secondary selector and the second secondary selector, for example, an instruction A1 to an instruction a12 are instructions for increasing the rate by 100M, at this time, the rate difference value is 100M and is an instruction A1, the instruction a12 is a control instruction after the control of adding the first secondary selector and the second secondary selector under the instruction A1, that is, the instruction a12 is determined to be a high-precision rate driving instruction, that is, an instruction for adding the control of the first secondary selector and the second secondary selector, and no high-precision scene is preferentially added, and this scheme is a final alternative scheme. And further determining a fourth feedback rate under the drive of the high-precision rate driving instruction, updating the feedback rate information based on the fourth feedback rate, and executing the step of determining the rate difference value between the input driving information and the feedback rate information. Thereby realizing accurate speed adjustment under different situations and further ensuring the functionality of the optical module.
