[0017] like Figure 1 The flowchart of the safety monitoring method applied to the high-voltage frequency conversion integrated machine provided by the embodiment of this specification is shown. Although this specification provides the method operation steps or device structure shown in the following embodiments or drawings, the method or device may include more or fewer operation steps or module units after partial merger based on routine or no creative labor. In the steps or structures where there is no necessary causal relationship logically, the execution order of these steps or the module structure of the device is not limited to the execution order or module structure shown in the embodiments or drawings of this specification. When the method or module structure is applied in actual devices, servers or terminal products, it can be executed sequentially or in parallel according to the method or module structure shown in the embodiments or drawings (for example, in a parallel processor or multi-threaded processing environment, or even in a distributed processing or server cluster implementation environment).

[0018] The safety monitoring method for high-voltage frequency conversion integrated machine provided in the embodiments of this specification is as follows: Figure 1 As shown, the method specifically includes the following steps: Step S101: Obtain a video stream around the high-voltage frequency converter through a panoramic camera.

[0019] Specifically, the panoramic camera real-time monitoring module can monitor the video dynamics around the all-in-one machine in real time to obtain the video stream.

[0020] Step S102: Detect the video stream to obtain a segmentation mask of the target object, and determine the center point coordinates of the target object based on the segmentation mask.

[0021] Specifically, the all-in-one machine, server, or control chip captures images from the video stream and performs image processing. Image segmentation techniques are used to classify each pixel in the image into "detected target" and "background," and then an output segmentation mask M = (x, y) is generated, where M is the pixel and x and y are the pixel coordinates.

[0022] The center point coordinates of the target object are determined by the following formula: , , Where, is the horizontal coordinate of the center point c, is the vertical coordinate of the center point c.

[0023] Step S103: determining the state of the target object based on the preset warning area and the central coordinate point, wherein the state includes being inside the warning area and being outside the warning area.

[0024] Specifically, the warning area is a pre-divided area. The warning area is a polygonal area centered on the all-in-one machine and can be represented by a set of vertex coordinates. The vertex coordinates of the warning area are S={(x1,y1),(x2,y2),…(x n ,y n )}.

[0025] Step S104: issuing a safety warning based on the status.

[0026] In the embodiment of the present application, the security warning based on the status specifically includes: If the state is specifically located within the warning area, an audible and visual alarm is issued and the high-voltage frequency conversion integrated machine is stopped; If the state is specifically outside the warning area, an early warning is issued based on the distance between the target object and the warning area.

[0027] Specifically, the center point G(x G ,y G ). Use the ray intersection method to determine whether the center point of the target object is within the warning area. G ,y G ) Launch a horizontal ray along the positive X-axis. Calculate the number of intersections between the ray and the warning line: If the number of intersections is odd, the point is within the warning area. If the number of intersections is even, the point is outside the warning area.

[0028] In this embodiment of the present application, the distance between the target object and the warning area is determined by the following steps: Determining each boundary line of the warning area based on the vertex coordinates of the warning area; Determine whether the projection point of the center point coordinates onto each boundary line is within the corresponding boundary line; If so, the candidate distance is determined based on the coordinates of the projection point and the center point coordinates. If not, the candidate distance between the projection point and the corresponding boundary line is determined based on the coordinates of the projection point and the coordinates of the corresponding boundary line vertex, and the candidate distance with the smallest median value among the candidate distances is taken as the final determined distance.

[0029] Specifically, the following formula is used to determine whether the projection point is within the boundary line: u=(x Q -x1)(x2-x1)+(y Q -y1)(y2-y1) / (x2-x1) 2 +(y2-y1) 2 ); If 0≤u≤1, then the projected point Q is within the line segment. If u<0 or u>1, then the projected point Q is not within the line segment. If not, the distance from the point to the line segment is equal to the minimum distance from the point to the two endpoints of the line segment.

[0030] The candidate distance is determined based on the coordinates of the projection point and the center point coordinates, specifically by the following formula: ; Where d is the candidate distance, is the horizontal coordinate of the center point, is the horizontal coordinate of the projection point, is the vertical coordinate of the center point, is the vertical coordinate of the projection point.

[0031] The candidate distance between the projection point and the corresponding boundary line is determined based on the coordinates of the projection point and the coordinates of the corresponding boundary line vertex, specifically by the following formula: , , Where, is the first distance between the projection point and the first vertex in the corresponding boundary line, is the second distance between the projection point and the second vertex in the corresponding boundary line, is the horizontal coordinate of the center point, is the vertical coordinate of the center point, is the horizontal coordinate of the first vertex in the corresponding boundary line, is the ordinate of the first vertex in the corresponding boundary line, is the horizontal coordinate of the second vertex in the corresponding boundary line, is the ordinate of the second vertex in the corresponding boundary line, wherein the smallest median of the first distance and the second distance is taken as the candidate distance between the projection point and the corresponding boundary line.

[0032] If the state is specifically outside the warning area, an alarm is issued based on the distance between the target object and the warning area, specifically including: Recording a center point coordinate set of the target object based on a preset time period; determining a speed and direction of movement of the target object based on the center point coordinate set; When it is determined based on the speed and direction of movement of the target object that the target object enters the warning area after a preset time, an early warning signal is issued.

[0033] Specifically, when the target enters the video surveillance area, the historical coordinates of the target point G are continuously recorded. . And calculate the current speed and direction using the following formula: , , Where v is the velocity, For direction, is the horizontal coordinate of the target point recorded at the tth time interval, is the horizontal coordinate of the target point recorded at the t-1th time interval, is the ordinate of the target point recorded at the tth time interval, The ordinate of the target point recorded at the t-1th time interval; , and is the velocity component, calculated using the velocity captured at the last moment.

[0034] State prediction: x′=Fx, P′=FPFT+Q; Kalman gain: K = P′HT(HP′HT+R)-1; Output the predicted position (x′, y′).

[0035] Calculate the angle or direction of the predicted point: Δx=x′-x G ,Δy=y′-y G； θ′=atan2(Δy,Δx); θ deg ′=θ′×180 / πmod360; When the target object enters the warning area after the preset time t, an early warning signal is issued.

[0036] After determining the center point coordinates of the target object, the method further includes issuing a safety warning through the following scheme: Establish a polar coordinate system with the high-voltage frequency conversion integrated machine as the origin and the shaft extension end of the high-voltage frequency conversion integrated machine as 0°; Converting the center point coordinates into polar coordinates according to the polar coordinate system; A safety warning is performed based on the polar coordinates and the shaft extension end warning value, the shaft extension end opposite end warning value, and other range warning values of the high-voltage frequency conversion integrated machine.

[0037] On a 360° plane with the integrated machine as the origin and the extended end of the integrated machine as 0°, convert the center point of the moving target C(x, y) into polar coordinates C(r, θ), where: , , The shaft extension end of the integrated machine is connected to the transmission device and runs at high speed. It is strictly forbidden for staff to approach. Set the shaft extension end warning value a. The warning value of the opposite end of the shaft extension end has an operation indication and sets the alarm value c. The other range warning value b of the high-voltage frequency conversion integrated machine is as follows. Figure 3 Shown is a schematic diagram of the shaft extension end, the non-shaft extension end, that is, the opposite end of the shaft extension end, and other ranges.
