The invention discloses a method for monitoring an unbalanced state of two paths of currents, and relates to the technical field of power systems. When current passes through a first copper strip and a second copper strip of the current transformer, the first copper strip and the second copper strip respectively and independently generate a specific electric field, and the flow directions of the current in the first copper strip and the second copper strip are opposite; when the first current value is equal to the second current value, the output current between the S1 terminal and the S2 terminal of the secondary winding is zero; when the current value of the first path is greater than the current value of the second path, the output current between the S1 terminal and the S2 terminal of the secondary winding is a positive value; and when the current value of the first path is smaller than the current value of the second path, the output current between the S1 terminal and the S2 terminal of the secondary winding is a negative value. According to the arrangement, whether the first-path current and the second-path current of the primary end are balanced or not can be known by detecting the output current of the S1 terminal and the S2 terminal of the secondary end, and if the first-path current and the second-path current are not balanced, whether the first-path current is large or the second-path current is large is judged.

The invention discloses an underground garage property management vehicle intelligent detection method, which belongs to the technical field of image processing, and comprises the following steps: firstly, analyzing an image in an underground garage video, calculating a change characteristic value, and obtaining a vehicle driving image, a change position and a static image; then, the change position is removed, and brightness adjustment is carried out; then, by comparing the difference between the static image and the vehicle driving image, the vehicle is positioned, and the image of the vehicle to be detected is extracted; then, clustering processing is carried out on the to-be-detected vehicle image, a main color area of a vehicle body is identified, and the color similarity with the stored vehicle image is calculated; then, extracting classes in contact with the main color area of the vehicle body, constructing a color contrast vector, and further analyzing the similarity; and finally, through comparing the form values of the candidate vehicle image and the to-be-detected vehicle image, accurate identification of the to-be-detected vehicle is realized.
