Linear liquid injection machine for capacitance battery and liquid injection method thereof

The invention relates to a linear liquid injection machine for a capacitance battery and a liquid injection method thereof. The liquid injection machine comprises a rack, wherein a front weighing device, a front voltage measurement device, a linear guide way, a back voltage measurement device and a back weighing device are sequentially arranged on the rack, a normal-voltage liquid injection device is arranged on the rack arranged at one side of the linear guide way, and a tray is arranged on the linear guide way. The liquid injection method comprises the following steps of: weighing the weight of the battery which is not injected with liquid, and measuring the voltage; putting the battery with normally-tested voltage which is not injected with liquid into the tray, and pushing to the normal-voltage liquid injection device; computing the liquid injection quantity, and sequentially injecting liquid into a liquid injection barrel through a hibar pump till the required liquid injection quantity is reached; carrying out the normal-voltage liquid injection on the battery; weighing the weight of the liquid-injected battery, and measuring the voltage; and pushing the tray back to an initial position through the guide way, and resetting a positioning device to complete the one-time cycle of injected liquid. According to the invention, the whole operation is linear, the invention is high in work efficiency, and the functions of on-line voltage detection, normal-voltage liquid injection and on-line liquid compensation can be realized.

ActiveCN107248296AFlexible and efficient collection methodReduce complicated operationsImage enhancementImage analysisTraffic volumeHistogram
The invention discloses a video traffic flow statistical method based on an unmanned aerial vehicle and time sequence characteristics and belongs to the image processing technical field. According to the method, a traffic flow video is obtained through the photographing of the unmanned aerial vehicle above a road intersection; image matching is performed on the obtained video, so that influence caused by jitter can be eliminated; a background image is extracted through using a median value selecting method; each frame of image of the video is matched again with the background image; feature extraction is performed on specified regions of matched images, so that a feature time sequence histogram is obtained; and the feature time sequence histogram is analyzed, so that the traffic flow of lanes can be obtained. According to the method, regional features are simply and efficiently extracted, interference error caused by the jitter of the unmanned aerial vehicle is eliminated several times, and therefore, the statistics of the traffic flow is more accurate. The method has the advantages of simplicity, high efficiency, high adaptability, high expandability and a very broad application prospect.
