Background In a high-speed flying laser tab cutting control system, there are two general modes, namely, the speed of a conveyor belt is acquired by an encoder to an upper computer for data algorithm processing and then is sent to a vibrating mirror and a laser, but the speed of the current conveyor belt is fed back in real time when the pulse value of the encoder is updated very quickly, and the transmission speed of the upper computer and a bottom plate card cannot respond to the change of the speed, so that processed data has hysteresis, and the tab cut by the laser is not closed and exceeds under high speed. And secondly, the data of the encoder is given to a special algorithm chip of the control card for processing, which is limited by the processing speed of the algorithm chip. The disadvantage of using a specialized algorithm chip is that a high-speed algorithm processor, such as a DSP (DIGITAL SIGNAL Processing) chip, is required, and thus the hardware cost will be greatly increased, and the development difficulty will be greatly increased.
