Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The physiological waveform map drawing method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The doctor user can acquire the physiological state data of the user to be detected through the acquisition terminal and send the physiological state data to be drawn to the server 104. After the server 104 obtains the physiological state data to be rendered, the physiological state data to be rendered may be processed to obtain corresponding fragmented physiological state data. Server 104 may then determine target sliced physiological state data from the sliced physiological state data and send the target sliced physiological state data to terminal 102. Further, the terminal 102 may determine target physiological state data corresponding to the display interface based on the acquired target sliced physiological state data, and perform physiological waveform drawing based on the target physiological state data to generate a corresponding physiological waveform diagram. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.

In one embodiment, as shown in fig. 2, a physiological waveform mapping method is provided, which is described by taking the method as an example applied to the terminal in fig. 1, and includes the following steps:

step S202, acquiring target fragment physiological state data, wherein the target fragment physiological state data is obtained by a server according to the physiological state data to be drawn and is determined from the fragment physiological state data.

The physiological state data to be drawn refers to data of physiological state potential changes of an object to be detected in multiple periods, which are acquired through a terminal, and specifically may refer to electrocardiogram data, electroencephalogram data, electromyogram data, respiration data, blood oxygen data and the like. The physiological state data to be plotted may include a specific acquisition period, such as 8 points earlier to 8 points later, and may further include a specific acquisition frequency, such as 500 physiological state data acquired in 1 second.

In this embodiment, the physiological potential change data of the object to be detected in the preset detection interval can be collected through the terminal device installed on the user to be detected, so as to obtain the physiological state data to be drawn, and the physiological state data is sent to the server, so that the server can perform subsequent processing conveniently.

In this embodiment, the rendering and drawing of the physiological waveform are performed for the purpose of being displayed to a front-end user for viewing, for example, taking electrocardiographic monitoring as an example, a doctor performs corresponding analysis on the cardiac function of the object to be detected according to the displayed electrocardiographic waveform. And the storage space of the web front end is limited, and the complete physiological state data to be drawn cannot be completely stored.

In this embodiment, after acquiring the to-be-rendered physiological state data, the server may generate corresponding fragmented physiological state data based on the to-be-rendered physiological state data.

In this embodiment, the server generates the corresponding sliced physiological state data based on the to-be-drawn physiological state data, which may be single-slice sliced physiological state data or at least two slices of sliced physiological state data, for example, when the data volume of the to-be-drawn physiological state data is small, the server may not perform any processing, and directly uses the to-be-drawn physiological state data as sliced physiological state data, and when the server determines that the data volume of the to-be-drawn physiological state data is large, the to-be-drawn physiological state data may be processed at this time to obtain the corresponding at least two slices of sliced physiological state data.

Specifically, the criterion of the larger or smaller data amount may be determined according to the storage capacity of the front end (i.e., the terminal), or may also be set to a fixed value, which is not limited in this application.

In this embodiment, the server processes the physiological status data to be rendered to obtain the corresponding at least two pieces of sliced physiological status data, which may be to perform slicing processing on the physiological status data to be rendered to generate the corresponding at least two pieces of sliced physiological status data.

In this embodiment, the server may segment the acquired physiological state data to be rendered from the time dimension to obtain at least two pieces of corresponding sliced physiological state data.

Specifically, when the server segments the physiological state data to be rendered, the physiological state data to be rendered may be segmented according to a data amount storable by the web front end, for example, if the maximum data amount storable by the web front end is 100M, the data amount of each segmented physiological state data obtained by segmentation should be at least less than 100M.

Meanwhile, the server should combine the interface display data volume of the display interface of the terminal to segment the physiological status data to be drawn, for example, the number of the physiological status collection points that can be displayed at the same time point on the display interface is 5000 points, and actually during segmentation, it should be determined that the number of the physiological status collection points included in each piece of physiological status data should be at least greater than or equal to 5000 points.

In this embodiment, the server may comprehensively consider the storage capacity of the web front end and the number of the physiological status collection points that can be displayed at the same time point on the display interface, and segment the physiological status data to be drawn to obtain the corresponding segmented physiological status data.

In this embodiment, after obtaining the fragmented physiological status data, the server may determine the target fragmented physiological status data from the determined fragmented physiological status data, and send the target fragmented physiological status data to the terminal, so that the terminal may store the target fragmented physiological status data and perform subsequent processing.

In this embodiment, when the fragmented physiological status data only has a single chip, the server may directly transmit the fragmented physiological status data to the terminal.

In this embodiment, when the sliced physiological state data includes at least two slices, the server may determine, according to the collection time sequence of each sliced physiological state data, that the sliced physiological state data with the most advanced collection time sequence is the target sliced physiological state data when the physiological waveform is drawn for the first time, and send the target sliced physiological state data to the terminal. And when the sliding browsing is carried out subsequently, according to the sliding distance and the target fragment physiological state data determined before the sliding, re-determining or adjusting the target fragment physiological state data according to the acquisition time sequence, and replacing the target fragment physiological state data stored in the terminal.

The following description will take an example of a process of processing electrocardiographic data.

Specifically, a doctor can acquire myocardial action potential change data of an object to be detected through acquisition equipment to obtain electrocardiogram data to be drawn, and send the electrocardiogram data to a server so as to facilitate subsequent processing of the server.

In this embodiment, after the server acquires the electrocardiographic data to be drawn, the server may determine the electrocardiographic data to be drawn to determine whether the electrocardiographic data to be drawn needs to be processed.

Specifically, the server may determine whether to perform slicing processing on the electrocardiographic data to be drawn based on a preset fixed value or the storage capacity of the front end (i.e., the terminal).

In this embodiment, when the server determines that the data volume of the electrocardiographic data to be rendered is smaller than a preset fixed value or the storage capacity of the front end (i.e., the terminal), the server may determine not to perform slicing processing on the electrocardiographic data to be rendered, and directly use the electrocardiographic data to be rendered as sliced electrocardiographic data. Similarly, when the server determines that the data volume of the electrocardiographic data to be drawn is greater than or equal to a preset fixed value or the storage capacity of the front end (i.e. the terminal), the server can determine that the electrocardiographic data to be drawn is subjected to slicing processing to obtain at least two pieces of sliced electrocardiographic data.

Further, the server can determine target segmented electrocardiogram data from the obtained segmented electrocardiogram data and send the target segmented electrocardiogram data to the terminal, so that the terminal can perform subsequent processing.

And step S204, determining target physiological state data corresponding to the display interface according to the target fragmented physiological state data.

In this embodiment, the target sliced physiological state data acquired by the terminal cannot be completely displayed on the display interface at the same time point (on one screen), so that the terminal can determine the target sliced physiological state data that can be displayed on one screen by the display interface from the acquired target sliced physiological state data, and perform subsequent processing.

Specifically, the terminal may determine the target physiological state data corresponding to the display interface from the target sliced physiological state data according to the display parameters of the display interface, and perform subsequent processing. And continuously taking the electrocardiogram data as an example, namely determining the target electrocardiogram data corresponding to the display interface from the target sliced electrocardiogram data by the terminal, and performing subsequent processing.

And step S206, drawing the physiological waveform based on the target physiological state data, and generating a corresponding physiological waveform map.

In this embodiment, the terminal may perform the drawing of the physiological waveform according to the determined target physiological status data, and display the physiological waveform on the display interface, as can be seen with reference to fig. 3. Figure 3 illustrates a schematic diagram of an electrocardiographic waveform plot, as drawn in one embodiment.

Referring to fig. 3, the physiological waveforms drawn by the server may include electrocardiographic waveforms corresponding to different lead scale lines, for example, electrocardiographic waveforms corresponding to 12 lead scale lines, that is, electrocardiographic data corresponding to different lead scale lines of each physiological state acquisition point may be included in the target physiological state data determined by the server.

In the method for drawing the physiological waveform map, the target fragmented physiological state data is obtained by the server according to the physiological state data to be drawn, is determined from the fragmented physiological state data, then determines the target physiological state data corresponding to the display interface according to the target fragmented physiological state data, and draws the physiological waveform based on the target physiological state data to generate the corresponding physiological waveform map. Therefore, the data stored in the front end is only the target sliced physiological state data determined after slicing, the data amount stored in the front end can be reduced, and the storage requirement of the front end is met. And the target physiological state data is determined directly from the target fragmented physiological state data stored at the front end, the physiological waveform is drawn, and the physiological waveform map is generated.

In one embodiment, determining the target physiological state data corresponding to the display interface according to the target sliced physiological state data may include: determining initial physiological state data corresponding to the display interface based on the target fragment physiological state data; receiving a scrolling instruction of a scrolling control, wherein the scrolling instruction carries scrolling information; and determining the scrolled target physiological state data corresponding to the display interface based on the scroll information and the initial physiological state data.

The initial physiological state data refers to physiological state data corresponding to a physiological waveform drawn on a display interface before the scroll control is scrolled.

The scroll command is a command generated when the user scrolls through the scroll control, for example, a scroll command generated by a doctor sliding a mouse wheel. The rolling instruction summary carries rolling information, for example, the number of pixels of a pixel point rolling on the display interface, and the like.

In this embodiment, when the terminal performs the first time of drawing the physiological waveform, it may be determined that, from the acquired target sliced physiological state data, the physiological state data of the physiological state acquisition point closest to the acquisition time point is the target physiological state data corresponding to the first time of presentation, and the physiological waveform is drawn.

Further, when the terminal receives a scrolling instruction of the scrolling control, the physiological waveform data drawn on the display interface before scrolling can be used as initial physiological state data, target physiological state data of a physiological waveform to be drawn on the display interface after scrolling is determined according to the initial physiological state data and the scrolling information, and the physiological waveform is drawn.

Specifically, the terminal may determine, according to the number of pixels of the scrolling pixel points determined in the scrolling information, the number of physiological state acquisition points scrolled by the scrolling control, for example, one pixel on the display interface corresponds to 5 physiological state acquisition points, and if the number of the pixels scrolled is 100px, the number of the physiological state acquisition points scrolled is determined to be 500. Then, the terminal can determine that the rolling control member rolls from the target slicing physiological state data according to the initial physiological state data and the determined number of the rolling physiological state acquisition points, and then the target physiological state data of the display interface is correspondingly displayed.

In this embodiment, when the target segmented physiological state data is target segmented electrocardiographic data corresponding to electrocardiographic data, the initial physiological state data and the target physiological state data are initial electrocardiographic data and target electrocardiographic data corresponding to the target segmented electrocardiographic data, respectively. Similarly, when the target sliced physiological state data is the target sliced electroencephalogram data corresponding to the electroencephalogram data, the initial physiological state data and the target physiological state data are respectively the initial electrocardiograph data and the target electroencephalogram data corresponding to the target sliced electroencephalogram data.

In the above embodiment, the scrolling instruction of the scrolling control is received, and the scrolled target physiological state data corresponding to the display interface is determined based on the scrolling information and the initial physiological state data carried in the scrolling instruction, so that the scrolling deviation amount can be accurately determined based on the scrolling information, the scrolled target physiological state data can be accurately determined, and the accuracy of drawing the subsequent physiological waveform can be improved.

In one embodiment, determining the scrolled target physiological state data of the corresponding display interface based on the scroll information and the initial physiological state data may include: acquiring display parameters of a display interface and acquisition parameters of physiological state data to be drawn; determining the display quantity of the physiological state acquisition points which can be displayed simultaneously on the display interface based on the display parameters and the acquisition parameters; determining an initial absolute position of the initial physiological state data relative to the physiological state data to be plotted based on the initial physiological state data; determining a rolling offset of rolling according to the rolling information; and determining the scrolled target physiological state data corresponding to the display interface according to the scroll offset, the display quantity and the initial absolute position.

The display parameters may include parameter data such as a total pixel width of a display interface of the display interface, a unit pixel value of the display interface, and the like, and data such as an interface size width occupied by the physiological state acquisition point on the display interface in unit time. The collection parameters of the physiological status data to be plotted may refer to collection frequency of the collection device collecting the physiological status collection points, for example, the collection number of the physiological status collection points collected in unit time.

In this embodiment, the terminal may obtain the display parameters of the display interface and the acquisition parameters of the physiological status data to be drawn from the database, and then determine the display number of the physiological status acquisition points that can be simultaneously displayed on the display interface based on the display parameters and the acquisition parameters, as shown in fig. 4 by pointOfScreen (screen point).

Further, the terminal may determine, according to the initial point data, an initial absolute position of a first physiological state acquisition in the initial physiological state data relative to the physiological state data to be drawn, that is, an initial absolute position preAbsStart of a leftmost physiological state acquisition point of a previous screen pre in fig. 4 relative to a starting point start of the physiological state data to be drawn. In fig. 4, pre denotes a previous screen, current denotes a current screen, and next denotes a next screen.

In this embodiment, the initial absolute position preAbsStart may be determined according to the slice serial number of the target slice physiological state data and the data volume of each slice physiological state data, for example, if the slice serial number of the target slice physiological state data is 4, the data volume of each slice physiological state data is 10000 physiological state acquisition points, then the initial absolute position preAbsStart is 4 × 10000 ═ 40000, and then the initial absolute position preAbsStart is 40000.

Further, the terminal may determine a scroll offset of scrolling according to the scroll information, which is shown in scrollPointNum in fig. 4.

Further, the terminal may determine the scrolled target physiological state data corresponding to the display interface according to the scroll offset scrollPointNum, the display quantity pointOfScreen, and the initial absolute position preabstart, that is, determine the physiological state data corresponding to the current screen current in fig. 4.

In the above embodiment, the display quantity of physiological status acquisition points that can be simultaneously displayed on the display interface is determined according to the display parameters of the display interface and the acquisition parameters of the physiological status data to be drawn, the initial absolute position of the initial physiological status data relative to the physiological status data to be drawn is determined based on the initial physiological status data, the rolling offset of rolling is determined according to the rolling information, and then the rolled target physiological status data corresponding to the display interface is determined according to the rolling offset, the display quantity and the initial absolute position.

In one embodiment, as mentioned above, the display parameters may include a total pixel width of the display interface, a unit pixel value of the display interface, and an interface size width occupied by the physiological condition collection points collected in a unit time on the display interface, and the collection parameters include a collection number of the physiological condition collection points collected in the unit time.

The total pixel width of the display interface can be represented as gridWidth, the unit pixel value of the display interface can be represented as cellPx, the interface size width occupied by the physiological state acquisition points acquired in unit time on the display interface can also refer to the paper feeding speed in the physiological waveform diagram, and can be represented as speedValue, and the acquisition number of the physiological state acquisition points acquired in unit time can be represented as samplingrate.

In this embodiment, determining the display number of the physiological status acquisition points that can be simultaneously displayed on the display interface based on the display parameters and the acquisition parameters may include: determining the interface pixel width occupied by the physiological state acquisition points acquired in unit time on the display interface according to the interface size width occupied by the physiological state acquisition points acquired in unit time on the display interface and the unit pixel value of the display interface; determining the acquisition point pixel width between two adjacent acquisition points according to the interface pixel width and the acquisition number of the physiological state acquisition points acquired in unit time; and determining the display number of the physiological state acquisition points which can be simultaneously displayed on the display interface according to the total pixel width and the acquisition point pixel width.

In this embodiment, the terminal may determine the interface pixel width occupied by the physiological status acquisition point acquired in the unit time on the display interface, that is, cellPx _ speedValue, according to the interface size width occupied by the physiological status acquisition point acquired in the unit time on the display interface, that is, the paper feeding speed speedValue, and the unit pixel value cellPx of the display interface.

Further, the terminal may determine an acquisition point pixel width (cellPx _ speedValue)/samplingrate between two adjacent acquisition points according to the interface pixel width cellPx _ speedValue and the acquisition number samplingrate of the physiological state acquisition points acquired in unit time.

Further, the terminal may determine the display number of the physiological state acquisition points that can be simultaneously displayed on the display interface according to the total pixel width gridWidth and the acquisition point pixel width (cellPx _ speedValue)/samplingate, that is, the following formula (1).

Floor is a front-end common function, which means taking an integer downward. The following is a description by a specific example.

For example, the total pixel width gridWidth of the display interface is 1000px, the unit pixel value cellPx of the display interface is 4px, one cell in the display interface is 1mm, namely one cell is 4px, the paper feeding speed speedValue is 25mm/s, namely 25 cells are fed in 1 second, the acquisition number samplinglate of the physiological state acquisition points acquired in unit time is 500, and the display number of the physiological state acquisition points which can be simultaneously displayed on the display interface is 5000 through the formula.

In the above embodiment, the display number of the physiological state acquisition points which can be simultaneously displayed on the display interface is determined based on the display parameters and the acquisition parameters of the display interface, and the display number of the display interface in each specific application scene can be acquired, so that the subsequent physiological waveform drawing is adjusted based on the actual application scene, and the flexibility of the physiological waveform drawing is improved.

In one embodiment, determining the scrolled target physiological state data corresponding to the display interface according to the scroll offset, the display number, and the initial absolute position may include: determining the target absolute position of the scrolled target physiological state data to be determined relative to the physiological state data to be drawn according to the scrolling offset, the display quantity and the initial absolute position; determining the absolute position of the target sliced physiological state data relative to the slice of the physiological state data to be drawn according to the slice sequence of the target sliced physiological state data; and determining the rolled target physiological state data corresponding to the display interface according to the target absolute position and the fragment absolute position.

In this embodiment, the terminal may determine the target absolute position currentAbsStart of the scrolled target physiological state data to be determined relative to the physiological state data to be rendered according to the scroll offset scrollPointNum, the display number pointOfScreen, and the initial absolute position preabstart, that is, may determine the target absolute position currentAbsStart of the scrolled target physiological state data to be determined relative to the physiological state data to be rendered according to the following formula (2).

currentAbsStart＝preAbsStart+pointOfScreen+scrollPointNum (2)

Further, as described above, the terminal may determine, according to the fragment sequence of the target fragment physiological state data, a fragment absolute position sliceabstart of the target fragment physiological state data relative to the physiological state data to be rendered, for example, a fragment number of the target fragment physiological state data is 4, a data amount of each fragment physiological state data is 10000 physiological state acquisition points, an initial absolute position preAbsStart is 4 × 10000 ═ 40000, and an initial absolute position preAbsStart is 40000.

In this embodiment, the terminal may determine the scrolled target physiological state data corresponding to the display interface according to the target absolute position currentAbsStart and the slice absolute position sliceabstart when determining the scrolled target absolute position currentAbsStart of the target physiological state data relative to the physiological state data to be rendered and the slice absolute position sliceabstart of the target slice physiological state data relative to the physiological state data to be rendered. That is, the target physiological state data can be determined by the following formula (3).

currentStart＝currentAbsStart-sliceAbsStart (3)

In this embodiment, the terminal may intercept the determined target physiological status data, obtain physiological status data ecgScreenData of which the current screen of the display interface can perform a physiological status rendering with a length of pointOfScreen, and perform rendering of a physiological waveform.

In one embodiment, the target sliced physiological state data may include current sliced physiological state data in which the initial physiological state data is located and preloaded sliced physiological state data corresponding to the current sliced physiological state data.

The preloaded slice data may include left-wing slice data and/or right-wing slice data of the current slice physiological state data. In this embodiment, the left wing segment data or the right wing segment data may refer to one segment physiological state data or may refer to a plurality of segment physiological state data, which is not limited in this application.

For example, with continued reference to fig. 4, the current sliced physiological state data in which the initial physiological state data is located may be slice i, the left wing sliced data may not exist, and the right wing sliced data may be slice i + 1.

In this embodiment, after determining the scrolled target physiological state data corresponding to the display interface based on the scroll information and the initial physiological state data, the method may further include: judging whether the current sliced physiological state data of the target physiological state data is consistent with the current sliced physiological state data of the initial physiological state data; and when the current fragmented physiological state data of the target physiological state data is not consistent with the current fragmented physiological state data of the initial physiological state data, acquiring preloaded fragmented data of the current fragmented physiological state data corresponding to the target physiological state data from the server according to the current fragmented physiological state data of the target physiological state data.

In this embodiment, after the terminal performs the rolling preview on the physiological waveform displayed on the display interface through the rolling control, and determines the target physiological state data corresponding to the display interface after the rolling, that is, the target physiological state data of the current screen is determined, the server may determine whether the current sliced physiological state data in which the target physiological state data is located is consistent with the current sliced physiological state data in which the initial physiological state data is located, that is, determine whether the sliced physiological state data in which the physiological state data of the previous screen is located is the same sliced physiological state data as the sliced physiological state data in which the physiological state data of the current screen is located.

In this embodiment, when the terminal determines that the current sliced physiological state data in which the target physiological state data is located is consistent with the current sliced physiological state data in which the initial physiological state data is located, it indicates that after the user rolls through the rolling control, the physiological waveform drawn by the display interface does not roll to the next sliced physiological state data of the current sliced physiological state data in which the initial physiological state data is located, and at this time, the server may not process the physiological waveform.

Further, when the terminal determines that the current sliced physiological state data of the target physiological state data is inconsistent with the current sliced physiological state data of the initial physiological state data, it may be determined that after the user rolls through the rolling control, the physiological waveform drawn by the display interface has rolled to the next sliced physiological state data (sliding to the right) or the previous sliced physiological state data (sliding to the left) of the current physiological state data of the initial physiological state data, and at this time, the terminal may obtain the preloaded sliced physiological state data of the current sliced physiological state data corresponding to the target physiological state data from the server, and according to the determined new target sliced physiological state data, the terminal locally stores the target sliced physiological state data. For example, referring to FIG. 5, the current sliced physiological state data in which the initial physiological state data is located is slice i, and the preloaded sliced physiological state data is slices i-1 and i + 1. When the user scrolls to the left through the scroll control and scrolls to the slice i-1, the preloaded slice data can be determined to be the slice i-2 and the slice i again. Similarly, when the user scrolls to the right through the scroll control and scrolls to the slice i +1, the preloaded slice data can be determined to be the slice i and the slice i +2 again.

In one embodiment, the terminal may also determine the preloaded slice data after the scrolling in another manner, for example, the terminal may determine whether to re-determine the preloaded slice data according to the data amount of the target physiological state data determined after the scrolling and the first physiological state acquisition point of the target slice physiological state data, and if the starting point of the target physiological state data determined after the scrolling and the tail end of the target slice physiological state data determined after the scrolling are less than the preset number of screens when the scrolling control scrolls the physiological waveform diagram to the right, re-determine the corresponding preloaded slice data, that is, the next slice physiological state data of the preloaded right wing slice data. Similarly, when the rolling control member rolls the physiological waveform diagram to the left and the distance between the starting point of the target physiological state data determined after rolling and the starting point of the target sliced physiological state data is less than the length of the preset number of screens, the corresponding preloaded sliced data, namely the previous sliced physiological state data of the preloaded left-wing sliced data, is determined again. The details will be described below.

Specifically, when the terminal is loaded for the first time, two sliced physiological state data with a slice sequence of 0 and 1 are obtained. At this time, the physiological state data of the target segment is a set [ 0,1 ] of the segment 0 and the segment 1. And the physiological waveform drawn by the display interface is the physiological state data of the start point of the slice 0. At this time, when the scroll control is scrolled to the left, the physiological waveform displayed at the front end does not change, i.e., the scrolling to the left is invalid.

Further, when the user scrolls to the right through the scroll control, the terminal may determine whether the distance between the starting point of the target physiological state data of the current screen after scrolling and the tail end of the collection [ 0,1 ] is greater than or equal to a preset length, for example, whether the distance between the starting point of the target physiological state data of the current screen after scrolling and the tail end of the collection [ 0,1 ] is greater than or equal to 4 screen lengths, and when the distance between the starting point of the target physiological state data of the current screen after scrolling and the tail end of the collection [ 0,1 ] is less than the preset length, preload the sliced physiological state data with the sliced sequence of 2, that is, determine that the sliced physiological state data with the sliced sequence of. The physiological state data of the target segment at this time is a set [ 0,1, 2 ]. When the user continues to scroll to the right through the scroll control, the determined target fragment physiological state data can be a set [ i-1, i, i +1 ], and so on. And when the last segment is scrolled to and the display interface displays the physiological waveform of the last physiological state acquisition point, determining that the physiological waveform cannot be scrolled to the right continuously and scrolling to the right continuously is invalid.

Further, when the terminal determines that the current target sliced physiological state data is the set [ i-1, i, i +1 ], and the user scrolls leftwards through the scroll control, the terminal can judge whether the distance between the starting point of the scrolled current screen target physiological state data and the starting point of the set [ i-1, i, i +1 ] is greater than or equal to the preset length, and when the distance between the starting point of the scrolled current screen target physiological state data and the starting point of the set [ i-1, i, i +1 ] is less than the preset length, the terminal can preload the sliced physiological state data with the sliced sequence i-2, that is, the sliced physiological state data with the sliced sequence i-2 is determined to be the preloaded sliced data. The physiological state data of the target segment at this time is a set [ i-2, i-1, i ]. By analogy, the user can continue to scroll to the left through the mouse until the physiological state data of the segment with the segment sequence of 0 is scrolled.

In the embodiment, the pre-loaded fragment data of the current fragment physiological state data is determined, and the current fragment physiological state data and the corresponding pre-loaded fragment data are stored as new target data, so that when the current fragment physiological state data and the corresponding pre-loaded fragment data roll through the rolling control, data required by the display interface for drawing the physiological waveform can be obtained locally from the front end all the time.

In one embodiment, as described above, the physiological status data to be rendered may be electrocardiographic data to be rendered, the sliced physiological status data may be sliced electrocardiographic data corresponding to the electrocardiographic data to be rendered, the target sliced physiological status data may be target sliced electrocardiographic data corresponding to the sliced electrocardiographic data, the target physiological status data may be target electrocardiographic data corresponding to the target sliced electrocardiographic data, and the physiological waveform may be an electrocardiographic waveform.

In this embodiment, performing a physiological waveform mapping based on the target physiological state data to generate a corresponding physiological waveform map may include: acquiring the electrocardio parameters of an electrocardio oscillogram to be drawn and the display parameters of a display interface; determining the lead coordinate position of each lead wire based on the electrocardio parameters; determining a first coordinate position of each physiological state acquisition point on a display interface according to the lead coordinate position, the display parameters and acquisition point data of each physiological state acquisition point in the target electrocardiogram data; determining a second coordinate position of each physiological state acquisition point on the display interface according to the display parameters and the acquisition point data of each physiological state acquisition point; and determining the coordinate position of each physiological state acquisition point on a display interface based on the first coordinate position and the second coordinate position of each physiological state acquisition point, and drawing physiological waveforms to obtain an electrocardiogram waveform diagram corresponding to the target electrocardiogram data.

The electrocardiographic parameters may include the aforementioned acquisition parameters of the electrocardiographic oscillogram to be drawn and the corresponding physiological state data acquired by each physiological state acquisition point.

In this embodiment, the terminal may determine the lead coordinate position of each lead line according to the electrocardiographic parameters. As shown in fig. 6. For example, the terminal may calculate a y coordinate set of the 12-lead ruler line on a Canvas according to the acquired electrocardiographic parameters. First, the server calculates the distance between adjacent lead ruled lines, which is dis ═ (Canvas height-50)/12, where 50 is the pixel value of the last lead V6 from the bottom of Canvas, and Canvas height. Then, the terminal calculates the y coordinate of the scale line of the ith lead, which is yBegins [ i ] - (i +1) × dis, wherein i is a subscript of 12 leads, and the numeric area is [ 0,11 ].

Further, the terminal can determine the first coordinate position of each physiological state acquisition point on the display interface, namely the y position coordinate of each physiological state acquisition point on the display interface, according to the lead coordinate position, the display parameters and the acquisition point data of each physiological state acquisition point (or called as an electrocardiogram acquisition point) in the target electrocardiogram data.

Specifically, the terminal calculates the y position coordinates of each physiological state acquisition point on the display interface through formula (4), as shown below.

y＝yBegins[i]+ecgScreenData[index][i]*(cellPx*ratioValue) (4)

Wherein, yBegins [ i ] (i +1) × sis, ecgScreenData is target electrocardiogram data, index is the sampling sequence number of each physiological state acquisition point in the target electrocardiogram data, the value range is [ 0 ], pointOfScreen-1 ], i is the subscript of 12 leads, and ecgScreenData [ index ] [ i ] is the voltage value of the ith lead of the ith acquisition point in the index of the target electrocardiogram data, and the unit is mv. ratioValue is amplitude and may be, for example, 10 mm/mv. The cell pixel value of the cellPx display interface may also be referred to as a screen cell pixel value, and ecgScreenData [ index ] [ i ] (cellPx _ ratio value) is a pixel value converted according to the voltage value. And finally, adding yBegins [ i ] to obtain the y position coordinate of each physiological state acquisition point on the Canvas.

Further, the terminal can determine a second coordinate position of each physiological state acquisition point on the display interface according to the display parameters and the acquisition point data of each physiological state acquisition point, namely, determine an x position coordinate of each physiological state acquisition point on the display interface.

Specifically, the terminal calculates the x position coordinates of each physiological state acquisition point on the display interface through formula (5), as shown below.

x＝index*(cellPx*speedValue/samplingrate) (5)

Wherein, index is a sampling sequence number of each physiological state acquisition point in the target electrocardiographic data, the value range is [ 0 ], pointOfScreen-1 ], cellPx is a screen cell pixel, the interface size width occupied on the speedValue display interface, that is, the paper feeding speed, and samplinglate is the acquisition number of the physiological state acquisition points acquired in unit time, which may also be referred to as a sampling frequency, and then (cellPx _ speedValue/samplinglate) is the pixel distance between two adjacent physiological state acquisition points on the canvas. Then, through index (cellPx _ speedValue/samplingyte), the x coordinate of each physiological state collection point on the Canvas can be obtained.

Further, after the terminal determines the first coordinate position and the second coordinate position of each physiological state acquisition point, namely the x coordinate position and the y coordinate position, the terminal can determine the coordinate position of each physiological state acquisition point on the display interface and draw the physiological waveform to obtain the physiological waveform diagram corresponding to the target electrocardiogram data.

Specifically, the terminal firstly calls clearRect (clear function) of the Canvas API to clear existing content on the Canvas, namely, to clear existing physiological waveforms, and then sequentially calls beginPath (start function, call and start a path branch), moveTo (jump function, move to a certain point), lineTo (connect function, from the point connecting the current point to the point after movement, the sum of moveTo and lineTo is a straight line), stroke (straight line definition function, defining a straight line), and the like of the Canvas API, so as to complete drawing of the physiological waveforms corresponding to the target electrocardiogram data.
