The invention belongs to the technical field of signal processing, and discloses a multi-sensor fusion dynamic balance analysis method, system, equipment, and medium. The multi-sensor fusion dynamic balance analysis method includes: collecting original vibrations including horizontal and vertical directions from industrial sites signal; determine the signal source to be analyzed through the amplitude and similarity information; decompose the original signal with the help of target empirical mode decomposition; determine the signal to be analyzed by blind source separation according to the similarity between the decomposed result and the original signal; use the target blind source The separation method realizes the decomposition of the signal; combines the results of blind source analysis to identify dynamic balance components; calculates the one-octave frequency amplitude and phase information of the blind source separation signal where the dynamic balance component is located through Fourier transform; uses the influence coefficient method to carry out dynamic balance weighting Calculate and obtain the dynamic balance calculation result. The invention can effectively remove the interference of other fault information mixed in the dynamic balance analysis frequency, essentially realize the dynamic balance of the equipment, and prolong the service time of the equipment after the dynamic balance.

The invention discloses an electric vehicle control equipment to provide an electric vehicle controller with advantages of good performance, convenient in maintaining and low production cost. The electric vehicle controller comprises a cavity type shell, a circuit board disposed in the shell and an end cap disposed on the outer end of the shell, and an inner pad disposed between the shell and theend cap. An inner protuberant ring rib (21), which fits tightly inner surface of the shell, is formed on the end cap; an inner protuberant ring rib (31), which is embed into the inner surface of therib (21), is formed on the end cap; and the rib (31) supports the rib (21). The controller in the invention achieves better sealing and waterproof performance, simple installation and convenient maintenance, is a replacing product to the existing electric vehicle controller.

The invention discloses a no-burr CMOS RF frequency divider which is based on multi-phase shifting. The invention can implement dual mode output of 4 / 5 division frequency ratio, radically eliminates the possibility of burr signal generation when the phase is shifted, and improves the working speed of the RF frequency divider. The no-burr CMOS RF frequency divider comprises a four-phase prescaler which is used for providing four benchmark signals with difference of 90 DEG sequentially to a high-speed output selection circuit; the output terminal of the high-speed output selection circuit comprises a 'logic or' operation; a logic control circuit is used for outputting enabling signals which can be shifted according to the output signals of the high-speed output selection circuit.

The invention discloses a sub-pixel positioning method for the midline laser center of a three-dimensional laser scanning system. Threshold segmentation is performed on the image, and the line laser is roughly extracted; the burr phenomenon of the line laser after rough extraction is eliminated, and the width of the line laser is further reduced; the sub-pixel level coordinates of the center of the line laser are obtained by using the improved center of gravity method, and then the Hough transform is used Corrects false object pixels in sub-pixel coordinates. This positioning method combines the improved center-of-gravity method and Hough transform, which can meet the needs of the 3D laser scanning system to obtain the sub-pixel coordinates of the line laser center in real time and accurately, and realize the sub-pixel precise positioning of the line laser center.
