Description

Technical Field

[0001] The present invention relates to the field of electrochemical energy storage stations, and in particular to an object recognition system in an electrochemical energy storage station using current identification. Background Art

[0002] Battery packs are connected in series and in parallel. Parallel battery packs require that each battery has the same voltage, and the output voltage is equal to the voltage of one battery. Parallel battery packs can provide stronger current. There are no excessive requirements for series battery packs, as long as the capacity of the batteries is similar. Series battery packs can provide higher voltages. Battery packs are widely used in people's lives. Series battery packs are used in TV remote controls, electronic toys, and flashlights.

[0003] In the prior art, electrochemical energy storage stations use battery packs as energy storage media and store energy on-site by charging the battery packs. However, if the battery packs in the electrochemical energy storage station are overcharged, the battery packs will have excessive chemical reactions, causing damage to the internal structure of the battery packs. In severe cases, toxic gas mists will be generated, and even the battery packs and their associated facilities will be burned. Therefore, a targeted monitoring mechanism is needed to identify and handle the above customized scenarios. Summary of the invention

[0004] In order to solve the technical problems in the prior art, the present invention provides an object recognition system in an electrochemical energy storage station using current identification, which can use a single pixel point of a received final enhanced image as a current pixel point to perform the following detection operations: when the hue component value, brightness component value and saturation component value of the current pixel point in the YUV space respectively fall within the hue component value interval, brightness component value interval and saturation component value interval corresponding to the aerosol, the current pixel point is used as an aerosol pixel point; otherwise, the current pixel point is used as other pixel points, and when the percentage of the number of aerosol pixels in the final enhanced image to the total number of pixels in the final enhanced image is greater than or equal to a set percentage limit, an aerosol extraction success signal is issued, thereby realizing intelligent identification of aerosol in the electrochemical energy storage station.

[0005] According to the present invention, there is provided an object recognition system in an electrochemical energy storage station using current identification, the system comprising:

[0006] A current identification device is provided in the electrochemical energy storage station, and is used to issue an aerosol identification request when the measured charging current of the battery pack of the electrochemical energy storage station is greater than or equal to the set current limit, and is also used to suspend the issuance of the aerosol identification request when the measured charging current of the battery pack of the electrochemical energy storage station is less than the set current limit;

[0007] A capture processing device is arranged in the electrochemical energy storage station and connected to the current identification device, and is used to start the capture processing of the environment where the battery pack of the electrochemical energy storage station is located when receiving the aerosol identification request, so as to obtain a corresponding directional capture image;

[0008] A first enhancement device, disposed in the electrochemical energy storage station and connected to the capture processing device, for performing distortion processing on the received directional capture image to obtain and output a corresponding first enhanced image;

[0009] A second enhancement device, connected to the first enhancement device, for performing a customized morphological process of dilation followed by erosion on the received first enhanced image, so as to obtain and output a corresponding second enhanced image;

[0010] a third enhancement device, connected to the second enhancement device, and configured to perform adaptive recursive filtering and median filtering on the received second enhanced image to obtain and output a corresponding final enhanced image;

[0011] An intelligent recognition device is connected to the third enhancement device and is used to perform the following detection operation on a single pixel point of the received final enhanced image as a current pixel point: when the hue component value, brightness component value and saturation component value of the current pixel point in the YUV space respectively fall within the hue component value interval, brightness component value interval and saturation component value interval corresponding to the aerosol, the current pixel point is used as an aerosol pixel point; otherwise, the current pixel point is used as other pixel points; the intelligent recognition device is also used to send an aerosol extraction success signal when the percentage of the number of aerosol pixels in the final enhanced image to the total number of pixels in the final enhanced image is greater than or equal to a set percentage limit; otherwise, an aerosol extraction failure signal is sent.

[0012] It can be seen that the present invention has at least the following three outstanding substantive features:

[0013] First: a single pixel point of the received final enhanced image is used as the current pixel point to perform the following detection operation: when the hue component value, brightness component value and saturation component value of the current pixel point in the YUV space respectively fall within the hue component value interval, brightness component value interval and saturation component value interval corresponding to the aerosol, the current pixel point is used as the aerosol pixel point; otherwise, the current pixel point is used as other pixel points; the intelligent recognition device is also used to send an aerosol extraction success signal when the percentage of the number of aerosol pixels in the final enhanced image to the total number of pixels in the final enhanced image is greater than or equal to a set percentage limit, thereby realizing intelligent recognition of aerosol in the electrochemical energy storage station;

[0014] Secondly: when the charging current of the battery pack of the electrochemical energy storage station exceeds the limit, the intelligent identification of the aerosol in the electrochemical energy storage station is triggered, thereby preventing the spread of battery pack accidents while reducing the time cost and computing cost of aerosol identification;

[0015] Again: targeted image content enhancement processing including distortion processing, customized morphological processing of dilation followed by corrosion, adaptive recursive filtering processing and median filtering processing is adopted to obtain a final enhanced image with better image quality, providing more reliable basic information for the subsequent intelligent identification of aerosol in electrochemical energy storage stations.
