The invention relates to a time-resolved spectral measurement method, device and equipment based on a multi-event time-to-digital converter, and a medium, and the method comprises the steps: carrying out the histogram statistics of photon signals of different time responses in each column of single-photon avalanche diodes in different laser pulse periods through the multi-event time-to-digital converter, the photon signal distribution of the photon signal of the specific wavelength corresponding to each column of single-photon avalanche diodes in different laser pulse periods is determined; the multi-event time-to-digital converter carries out delay combination on photon signal distribution in different laser pulse periods so as to determine a photon lifetime curve corresponding to the photon signal of the specific wavelength of each column of single-photon avalanche diodes. And integrating the photon lifetime curves corresponding to the photon signals of the specific wavelength of each column of single-photon avalanche diodes so as to construct the time-resolved spectrum of the sample to be detected. According to the invention, counting loss or time error caused by dead time can be reduced.

The utility model discloses a tablet candy canning, weighing and counting device which comprises a first conveyor belt, a second conveyor belt, connecting blocks and a first contact wheel, the second conveyor belt is arranged on the rear side of the first conveyor belt, and the two side edges of the top of the first conveyor belt and the two side edges of the top of the second conveyor belt are symmetrically connected with the connecting blocks at the same time.

The utility model discloses a piece counting conveying belt which comprises an installation frame, a belt roller, a belt and a main drive motor, safety optical gratings are fixedly installed on the two sides of the input end of the installation frame and located above the belt, counting sensors are installed on the two sides of the installation frame, the number of the counting sensors is two, and the counting sensors are located at the two ends of the installation frame respectively. The counting sensor located at the input end of the mounting rack is located on one side of the safety grating close to the output end of the mounting rack. Whether goods exist on the belt or not is detected through the safety optical grating, the possibility that a plurality of goods are placed on the mechanical arm within a certain range is reduced, the goods pass through the counting sensors after being conveyed to the outer side of the safety optical grating range and are counted through the counting sensors, and the two counting sensors are arranged for rechecking the number. The counting sensor located at the rear end ensures that the goods leave the belt, and counting errors are reduced.

The present invention is applicable to the field of image processing technology, and provides an intelligent counting method for sintered ore particles based on multi-level image feature matching, including: obtaining video data of ore particles in free fall after being crushed by a crusher; extracting the morphological features of each ore particle in the Kth frame ore particle image and the K+1th frame ore particle image in the video data, and based on the dynamic model and the extracted morphological features, tracking the morphological features of each ore particle in the Kth frame ore particle image in the K+1th frame ore particle image through multi-level feature matching, and obtaining the preliminary determination result of the area corresponding to each ore particle in the video data; respectively for each ore particle in the video data, determining the maximum area of ​​the ore particle according to the preliminary determination results of all areas corresponding to the ore particle; according to the preset ore particle area threshold and the maximum area of ​​each ore particle, dividing each ore particle into particle sizes, and counting the number of ore particles contained in different particle sizes. The present invention can improve the accuracy of sintered ore particle counting.

The utility model discloses a device and detection equipment for cable on-off detection and counting, design electronic technical field, the first input of first comparison unit connects resistance R5's first end, the second input of first comparison unit connects the first USB port among double -deck USB, the first end of resistance R12 is connected among the second USB port in double -deck USB, the second end of resistance R5 and the second end of resistance R12 ground, the first USB port and second USB port connect corresponding detection end, the output of first comparison unit connects the control end of first switch, the input of first switch connects the output of counting unit and the first power supply pin of double -deck USB, and the input of counting unit and the second power supply pin of double -deck USB connect power supply output end.
