The invention relates to the technical field of image processing, in particular to a toothpaste raw material detection method and system. The method comprises the following steps: generating a gray histogram of an image of a toothpaste raw material liquid level area at each moment; obtaining the slope of a connecting line between the maximum column height vertex and other non-zero column height vertexes in the gray level histogram, and determining the initial mixing degree of the toothpaste raw materials; acquiring a gradient value of each pixel point in the image; determining a low threshold value of a Canny operator; determining a high threshold value of a Canny operator; detecting the image according to the low threshold value and the high threshold value through a Canny operator to obtain edge pixel points of the image; in response to the fact that the ratio of the edge pixel points of the image to all the pixel points is smaller than a preset threshold value, it is determined that the toothpaste raw material liquid level area at the moment is evenly stirred so that toothpaste raw material detection can be completed. Through the low threshold value and the high threshold value of the self-adaptive Canny operator, reduction of detection accuracy caused by improper threshold value selection is avoided, and the quality of toothpaste is ensured.

This invention discloses a method and system for assessing the service status and diagnosing faults of cables, belonging to the field of cable aging and fault diagnosis technology. The method first constructs a simulation model of an equivalent cable and verifies the model. Based on the verified simulation model, it simulates the cable materials to obtain simulation data. Using the aging characteristic data and state characteristic data of the cable materials as training data, it trains an artificial neural network model, resulting in a cable prediction model. This model includes a fault prediction unit and an aging prediction unit, which are correlated probabilistically. The aging prediction unit outputs the aging state of the cable, and the fault prediction unit diagnoses faults based on probabilities. This method, through neural network model analysis, constructs a cable material identification and classification model under the influence of multiple interference factors, thereby achieving cable service status assessment and fault diagnosis.

The application discloses a switch cabinet interlocking protection mechanism and a switch cabinet, and relates to the technical field of electrical equipment, which comprises an outer protection shell, a disconnecting switch control mechanism, a rope, and a driving mechanism. The outer protection shell is arranged on a cabinet door. The driving mechanism is inserted into the outer protection shell. The driving mechanism comprises a mounting block, a rotating shaft body and a limiting piece. The rotating shaft body is provided with a clamping tooth. The mounting block is provided with three containing grooves. The rotating shaft body can be rotated by external force or translation. The clamping tooth of the rotating shaft body can be switched into different containing grooves. Under the action of the limiting piece, the clamping tooth is located in one containing groove. The position of the clamping tooth is switched to pull the rope to complete the opening and closing of the disconnecting switch. The structure is simple and ingenious. The operator can realize the opening and power-off before opening the door, and the safety is high. The rotating shaft body is provided with a handle disc. The jack on the handle disc is consistent with the position of the clamping tooth. The operator can intuitively observe the position of the clamping tooth to determine the state of the disconnecting switch.
