Specifically, the service end of the auxiliary system includes:
P130 graphics file generation module: the system comprises an interface extraction module, an electrocardiographic image acquisition module and a storage module, wherein the interface extraction module is used for receiving an acquisition file submitted by the interface extraction module and processing the acquisition file into an electrocardiographic image file;
The acquisition file is a video file, and can be converted into a transverse long picture file through the function provided by opencv. The content of the transverse long picture file is a waveform diagram of an electrocardiogram, and one effective electrocardiogram consists of a plurality of waveform diagrams, wherein the transverse axis is signal acquisition time, and the longitudinal axis is waveforms with consistent sampling time points, and the waveform diagram is shown in fig. 3. In the present invention, a plurality of waveforms having identical sampling time points are processed as one integral waveform, and as shown in fig. 3, the framed portion is the integral waveform at one time point. Based on this, the information related to the overall waveform at one point in time includes: the electrocardiographic sampling start time and end time, sampling time points and waveform region image characteristics, wherein the time length corresponding to the sampling time points is the unique identifier of the waveform, namely the waveform identifier P.
In the processing process, the transverse long picture file is compressed according to the image size and the processing capacity of the server under the condition of not affecting the overall definition, so that the subsequent image recognition and the transmission during the image recognition are facilitated.

Because the electrocardiograph sampling time is long, the electrocardiograph result cannot be displayed completely in one page of the window, and therefore the waveform to be processed is required to be positioned in the display area of the window, and waveform identification positioning is required when the position of the interference waveform in the window is selected;
Because the image file generating module compresses the long image file, the image pixels can be changed, and different displays and different window sizes can also enable the sizes of the display areas of the windows to be different. If a common positioning mode (such as pixel positioning) is adopted, each time a window or a picture changes, the picture attribute and the window attribute need to be captured again accurately, and the pixel point needs to be recalculated. In the electrocardiogram picture, the proportion of the acquisition time point corresponding to the waveform identifier to the total duration T does not change along with the image definition and the size of the window. In order to be compatible with the size of a window of an electrocardiogram system client, the resolution of a display and the size of a picture, and reduce the calculated amount when the window changes, the waveform identification positioning is carried out through the proportional relation between the total duration T and the waveform identification P.

wherein: k is the page number to which the waveform identification P belongs, and is expressed as k=math.ceil (P/W) if implemented using python,
Kp is the number of pages needed to be divided for displaying the electrocardiogram corresponding to the total duration T, and is expressed as follows, if python is adopted: kp=math.
2) The sampling time point positioning is used for determining that the waveform corresponding to the waveform identifier P is at the current window position:
the time point positioning method comprises the following steps: acquiring the width B of the window by a tool (such as a professional library of python), setting the leftmost point at the bottom of the window as an origin O' (0, 0), and setting the rightmost point O as O (B, 0) (as shown in fig. 5), wherein x=b in fig. 5;
determining a waveform identifier P corresponding to a graph width F=B/W;
acquiring the position Q, Q= ((P% W)/W) x B of the waveform identifier P corresponding to the time point at the current window; wherein P% W is P divided by W to obtain remainder;

Thus, the current window position of the waveform corresponding to the waveform identifier can be obtained.
In the simulation operation instruction, the position of the waveform identifier P corresponding to the image area, the mouse operation to be executed on the position and the keyboard operation are provided, so that the simulation operation of processing an interference waveform for an operator is realized.
For example: the total duration T is 85500, the waveform mark P is 7874 seconds, the time period W=30 seconds for which one page can be displayed, the length L of the scroll bar=1134px, the length L2=38px of the sliding block, and the width B=1200px of the window;
The waveform identification positioning calculation process comprises the following steps:
the waveform identifier P belongs to the page number k=math.ceil (P/W) =math.ceil (7874/30) =263;
the number of pages kp=math.ceil (T/W) =math.ceil (85500/30) =2850 of the electrocardiogram corresponding to the total time period T;
horizontal scrollbar slider position: l1=k× (L-L2)/kp=263× (1134-38)/2850=101 px;
Waveform identifier P corresponds to a pattern width f=b/w=1200/30=40;
the waveform mark P corresponds to the position q= ((P% W)/W) ×b= ((7874% 30)/30) ×1200=560 px where the time point is located in the current window;
The waveform identifier P corresponds to the starting and ending points of the image region in the lateral direction, S (540,0), E (580,0).
After the waveform identifier P is acquired to correspond to the transverse starting point and the transverse ending point of the image area, generating a simulation operation instruction according to the convention of the reference operation instruction, wherein the simulation operation instruction comprises the following steps: { area (540,580); key (alt, R); mouse: () }.
