Research on Error Compensation Method under Laser Level Detection

Aiming at the lack of measurement accuracy during the detection of the slurry liquid level, the laser ranging technology was used to detect the slurry level, and the error compensation for the use of the wave neuronic network to the detection of the slurry liquid level was proposed. First of all, the laser ranging method is used to carry out the slurry level detection experiment, analyze the measurement principle of the laser displacement sensor, find out the cause of the detection accuracy and the cause of errors, and establish a predictive model of laser level detection error based on the wavelet neural network. The results showed that the average detection error was reduced by 64.3%after adjusting the angle of laser incident. After applying the small wave neural network to the laser level detection error compensation, the measurement accuracy of the laser ranging sensor was effectively improved, and the measurement error of the laser displacement sensor measured was controlled to the actual situation to actual. Within the scope of the application, it has high practical value.
