The invention provides a method for tracking the trajectory of a moving object in a transformer substation based on a three-dimensional digital model, and relates to the technical field of safety management and control, the method is applied to a server of a transformer substation management and control system, the transformer substation management and control system comprises the server, a plurality of controllers and a plurality of laser point cloud sensors, and the server is connected with the plurality of controllers simultaneously. Each controller is connected with a laser point cloud sensor. The method comprises the following steps: acquiring first position data transmitted by a first controller; according to a preset transformer substation space structure, calculating the probability that the moving target moves to the scanning area of each sensor; if it is determined that the probability that the moving target moves to the second scanning area is larger than or equal to a preset threshold value, an acquisition instruction is sent to a second controller; receiving change data transmitted by the second controller; and generating a continuous motion state of the three-dimensional moving target according to the change data. According to the invention, the data volume transmitted during trajectory tracking of the moving object in the transformer substation based on the three-dimensional digital model can be effectively reduced.

This application relates to the field of machining technology and discloses a horizontal milling machining center, including a first guide rail, a second guide rail, and a tray. A milling body is mounted on the first guide rail, and a movable stage is mounted on the second guide rail. The movable stage is rotatable and used to fix the workpiece to be machined. The tray is detachably mounted on the movable stage. This horizontal milling machining center uses vertical and horizontal linear motion instead of traditional arc-shaped rotary motion to achieve tray exchange. Combined with an anti-contamination conical positioning structure and the significant differences in tray positioning states, it fundamentally solves the defects of existing technologies such as easy collisions during tray exchange, unstable positioning accuracy, and poor sensor reliability.
