In view of the problem that the traditional speed regulation of the black glue record machine has large error by means of the speed measuring code plate and the human eye,the speed measuring code plate and the fixed box which are attached to the black glue record machine as well as the infrared counter shooting device,the display and the processing module which are fixed with the fixed box are independently designed;the infrared counter shooting sensing technology,the Stm32 high-precision frequency measuring technology and the periodic speed measuring method are used to accurately calculate the speed of the black glue record machine and accurately display the speed information on the LCD;through error analysis and fitting error algorithm,the measurement error is limited within 0.4%,which greatly reduces the error caused by traditional human eye recognition.
