Hospitals will set up electronic interactive screens in each ward. The electronic interactive screens can not only display the data of medical equipment in the area, but also reflect the location data of each office or bed in the area. The most intuitive and effective way to display it is through maps, on which the data are statistically analyzed and regulated.

[0003] For example, users can zoom in and out on the map on the electronic interactive screen to query the location of each office, bed or medical equipment, and can also associate the corresponding fixed-point location with the target user's identity information to facilitate searching.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0064] The present invention is applied to the electronic interactive screen of the hospital. Taking the medical electronic whiteboard as an example, the medical electronic whiteboard is usually installed in the nurse station of the ward, or other locations convenient for medical care or patients to use. The medical electronic whiteboard becomes a large data interactive screen through the map data display method of the present invention. The user can zoom in and out the map through an external device to query the location of each office, bed or medical equipment, and can also associate the corresponding fixed-point location according to the identity information of the target user to achieve convenient search. It can also be understood that the display screen of the medical electronic whiteboard includes a touch screen, and the user can directly touch it to achieve zooming, moving, etc. The specific map in the related art is only used within the enterprise, including the hospital, and usually does not need to use huge functions. For example, the map is built based on the office space of the enterprise, and only a flat map is needed. If the traditional map construction method is used, the map will occupy a lot of memory resources when the map is running due to the huge map modeling and functions, and the memory of the terminal used within the enterprise is usually low, and its performance cannot support the huge modeled map.

[0065] Based on this, the embodiments of the present application provide a map processing method, device, electronic device and computer-readable storage medium, which can reduce the memory usage of the map so that terminals with lower memory configurations can also use the map.

[0066] The map processing method of the embodiments of the present application can be applied to a terminal or a server. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a router, a programmable switch, a network card, etc.; the server can be configured as an independent physical server, or as a server cluster or a distributed system composed of multiple physical servers, or as a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms; the software can be an application that implements the map processing method, etc., but is not limited to the above forms.

[0067] The present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform specific services or implement specific abstract data types. The present application can also be practiced in distributed computing environments, in which services are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0068] Reference Figure 1 , Figure 1 The map processing method of the first aspect of the present application is a flowchart of the steps of the map processing method of the first aspect of the present application. The map processing method of the first aspect of the present application may include but is not limited to steps S110 to S140.

[0069] Step S110, obtaining a scalable vector graphics file of the map;

[0070] It is worth noting that Scalable Vector Graphics (SVG) files are used to describe two-dimensional graphics and animations. SVG is an XML-based markup language used to describe two-dimensional vector graphics. Scalable vector graphics is a file format that stores vector graphics. Scalable vector graphics are vector-based, so they can be enlarged or reduced to any size without affecting clarity. Scalable vector graphics are displayed normally in browsers and can be displayed in browsers such as Chrome, Firefox, Safari, Edge, etc. Since Scalable Vector Graphics uses vector format, it takes up less memory when representing complex graphics.

[0071] Step S120, creating a first graphic container, and rendering a scalable vector graphic through the first graphic container to obtain a rendered map;

[0072] It is worth noting that the graphic container generally refers to an element used to embed scalable vector graphics in an HTML page. And the scalable vector graphics can be rendered through the graphic container. For example, refer to Figure 2 , Figure 2This is a schematic diagram of a rendered map according to an embodiment of the present application. Specifically, an external container is first created, and a business container is created in the external container. The business container is used to operate the map. Then, a first graphic container is created in the business container, and a scalable vector graphic is rendered through the first graphic container to obtain a rendered map.

[0073] It should be noted that HTML (HyperText Markup Language) page is a standard markup language used to create web pages.

[0074] Step S130, establishing a first coordinate system based on the rendered map;

[0075] For example, refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of establishing the first coordinate system in an embodiment of the present application. A rectangular first coordinate system is established with the lower left corner of the rendered map as the origin. It is worth noting that the map zoom ratio preset for the rendered map is 1, and the unit value of the first coordinate system is 1 pixel when the map zoom ratio is 1. The map zoom ratio, i.e., the map scale, is the proportional relationship between the distance on the map and the corresponding distance in the real world.

[0076] Step S140: in response to receiving an operation instruction for rendering a map, modifying properties of the first graphic container based on the operation instruction and the first coordinate system.

[0077] It is worth noting that the map processing method of the embodiment of the present application can be applied to a computer browser, the rendered map is displayed in the browser, and the user operates the rendered map through the mouse or keyboard, thereby generating operation instructions for the rendered map. The attribute of the first graphic container refers to the transform attribute, which is used to transform the SVG element. By setting or modifying the parameters in the transform attribute, the element can be translated, scaled, rotated, skewed, and other operations. The transform attribute can contain one or more transformation instructions, each separated by a space.

[0078] The map processing method of the embodiment of the present application, through steps S110 to S140, first obtains the scalable vector graphics of the map, then creates a first graphic container, and renders the scalable vector graphics through the first graphic container to obtain a rendered map, so as to construct a map based on SVG. Then, a first coordinate system is established based on the rendered map, and in response to receiving an operation instruction for the rendered map, the properties of the first graphic container are modified based on the operation instruction and the first coordinate system to achieve interaction with the rendered map. Since scalable vector graphics occupy low memory, the embodiment of the present application can reduce the memory usage of the map, so that terminals with low memory configuration can also use the map.

[0079] It is understandable that, referring to Figure 4 , Figure 4 for Figure 1 A specific flow chart of step S140 in FIG. Step S140 may include but is not limited to steps S410 to S440.

[0080] Step S410, in response to receiving a zoom instruction, obtaining a zoom value from the zoom instruction;

[0081] It is worth noting that the zoom value represents the zoom villa of the rendered map. For example, if the zoom value is 0.5, the rendered map is zoomed to 0.5 times the original size. For example, if the zoom value is 2, the rendered map is zoomed to 2 times the original size.

[0082] Step S420, determining the current coordinate value of the selected point in the first coordinate system, and determining the first physical location of the selected point based on the current coordinate value and a preset map zoom ratio;

[0083] It is worth noting that the selected point refers to the location selected by the user by clicking the mouse on the rendered map. The current coordinate value of the selected point is determined by the first coordinate system, and the first physical location of the selected point is determined based on the current coordinate value and the preset map zoom ratio. For example, if the current coordinate value is (x1, y1) and the map zoom ratio is 1, the coordinates of the first physical location are (x1, y1). It should be noted that the coordinate system of the first physical location is a second coordinate system established based on the actual physical location.

[0084] Step S430, modifying the scaling parameter in the properties of the first graphic container based on the scaling value;

[0085] Exemplarily, the scaling value is 2. The scaling parameters include sx (scale x), which defines the scaling ratio of the element along the x-axis. For example, sx (scale 2) will magnify the element by 2 times along the x-axis. The scaling parameters also include sy (scale y), which defines the scaling ratio of the element along the y-axis. For example, sy (scale 2) will magnify the element by 2 times along the y-axis.

[0086] Step S440: Determine a second physical location of the selected point based on the zoom value and the first physical location.

[0087] It is worth noting that the value of the x-axis in the second physical positioning = the scaling value * the value of the x-axis in the first physical positioning, and the value of the y-axis in the second physical positioning = the scaling value * the value of the y-axis in the first physical positioning.

[0088] For example, refer to Figure 5 , Figure 5 This is a schematic diagram of the selected point in the first coordinate system. Figure 5 Point A is the selected point, and the coordinates of the selected point in the second coordinate system are (1, 1), corresponding to the first physical location in the rendered map, which is one grid away from the X axis and one grid away from the Y axis, that is, x=1, y=1. Figure 6 , Figure 6 The coordinates of the selected point in the second coordinate system after scaling are shown in Figure 1. When the scaling value is 5, A' is the position of point A after scaling, and the second physical location of point A' is x=5, y=5.

[0089] The map processing method of the embodiment of the present application implements the zooming operation on the rendered map through steps S410 to S440. The operation is simple, and the user can control the rendered map to zoom in or out by using the mouse.

[0090] It is understandable that, referring to Figure 7 , Figure 7 The flowchart of the steps for generating the scaling instruction is shown in FIG. The scaling instruction is obtained by the following steps:

[0091] Step S710, monitoring the mouse wheel event;

[0092] Step S720: determining a zoom instruction based on the scroll wheel event.

[0093] Specifically, in JavaScript, the wheel event can be used to listen to the mouse wheel event. The wheel event is triggered when the user rolls the mouse wheel. When triggered, check the deltaY property of the event object, which represents the amount of scrolling of the wheel in the vertical direction. The zoom value can be obtained through the preset zoom conversion ratio. For example, the zoom value = scrolling amount * zoom conversion ratio. After obtaining the zoom value, a zoom instruction is generated based on the zoom value. It should be noted that JavaScript (JS) is an advanced, interpreted programming language. It is widely used in many fields such as web development, server-side development (through platforms such as Node.js), desktop applications, mobile applications, and game development.

[0094] It is understood that the operation instructions include translation instructions;

[0095] Reference Figure 8 , Figure 8 yes Figure 1 FIG. 1 is a schematic diagram of a specific flow chart of another embodiment of step S140 in FIG. 140 may also include but is not limited to step S810 and step S820.

[0096] Step S810, in response to receiving a translation instruction, determining a translation offset from the translation instruction;

[0097] Step S820: modify the translation parameters in the properties of the first graphic container based on the translation offset.

[0098] It is worth noting that the translation offset includes the offset on the x-axis and the offset on the y-axis. The translation parameters include tx(translate x) and ty(translate y). The tx(translate x) parameter defines the translation distance of the element along the x-axis. The ty(translate y) parameter defines the translation distance of the element along the y-axis. For example, if the offset on the x-axis is a and the offset on the y-axis is b, set the value of tx(translate x) to a and modify the value of ty(translate y) to b.

[0099] The map processing method of the embodiment of the present application realizes the translation of the rendered map through steps S810 to S820. The user can drag the rendered map with the mouse to generate a translation instruction, which is convenient for the user to translate the rendered map.

[0100] It is understandable that, referring to Fig. 9 , Fig. 9 The figure is a flow chart of the steps for generating the translation instruction. The translation instruction is obtained through the following steps:

[0101] Step S910, monitoring the mouse click event;

[0102] Step S920, determining the first current coordinate value of the point selected when the mouse is pressed based on the click event;

[0103] Step S930, determining the current coordinate value of the point selected when the mouse is released based on the click event;

[0104] Step S940, obtaining a translation offset based on the first current coordinate value and the second current coordinate value;

[0105] Step S950: When it is detected that the translation offset is a non-zero value, a translation instruction is generated based on the translation offset.

[0106] It is worth noting that in JavaScript, the mouse click event is monitored through the mousedown event. When the mouse is pressed, the first current coordinate value of the selected point is determined; when the mouse is released, the second current coordinate value of the selected point is determined. The second current coordinate value - the first current coordinate value = the translation offset. For example, the first current coordinate value is (x1, y1), and the second current coordinate value is (x2, y2), then the translation offset is (x1-x2, y1-y2). Then, when the translation offset is detected to be a non-zero value, it can be determined that the user drags and translates the rendered map with the mouse, and thus a translation instruction is generated based on the translation offset.

[0107] It is understandable that, referring to Fig.10 , Fig.10 This is a flowchart of a map processing method according to another embodiment of the present application. The map processing method according to the embodiment of the present application includes but is not limited to:

[0108] Step S1110, obtaining the current coordinate value of the selected point;

[0109] Step S1120, determining the current physical location of the selected point based on the current coordinate value as a marked point;

[0110] Step S1130, creating a second graphic container in the marking point, and adding a preset character mark to the second graphic container.

[0111] Specifically, refer to Fig.11 , Fig.11 This is a schematic diagram of a marked node and a pop-up window. A second graphic container is created at the marked point location, and a preset character tag is added to the second graphic container so that the second graphic container can render the preset character tag to display the character tag on the rendered map. The character tag is an HTML string. Fig.11 In the example, "01" is a character mark.

[0112] It is worth noting that, in one embodiment, after step S1130, when it is detected that the coordinate value of the mouse cursor is the same as the coordinate value of the marked point, the character mark of the second graphic container in the marked point is displayed.

[0113] In one embodiment, the marking point is a DOM node. A DOM (Document Object Model) node is the basic unit of the HTML and XML document structure. DOM is a programming interface that presents a document as a tree structure consisting of nodes and objects (node ​​objects), allowing programs and scripts to dynamically access and update the content, structure, and style of a document. Therefore, JavaScript can obtain and perform a series of operations on DOM nodes, such as changing content, adjusting styles, binding events, etc. For example, referring to Fig.11 , add a pop-up window to the DOM node through JavaScript. When the coordinate value of the mouse cursor is the same as the coordinate value of the marked point and the mouse is pressed, the pop-up window is displayed. Fig.11 In the window where "Zhang San" is located, it is a pop-up window.

[0114] Reference Fig.12 , Fig.12 A second aspect of the present application provides a map processing device, including:

[0115] An acquisition module 1210 is used to acquire a scalable vector graphics file of a map;

[0116] A creation module 1220, configured to create a first graphic container, and render a scalable vector graphic through the first graphic container to obtain a rendered map;

[0117] An establishing module 1230 is used to establish a first coordinate system based on the rendered map;

[0118] The modification module 1240 is configured to modify the properties of the first graphic container based on the operation instruction and the first coordinate system in response to receiving an operation instruction for rendering the map.

[0119] The map processing device of the embodiment of the present application is used to execute the map processing method of the embodiment of the first aspect of the present application. When executing the map processing method, the scalable vector graphics of the map are first obtained, and then a first graphic container is created. The scalable vector graphics are rendered by the first graphic container to obtain a rendered map. In this way, a map based on SVG is constructed. Then, a first coordinate system is established based on the rendered map. In response to receiving an operation instruction for the rendered map, the properties of the first graphic container are modified based on the operation instruction and the first coordinate system to achieve interaction with the rendered map. Since scalable vector graphics occupy low memory, the embodiment of the present application can reduce the memory usage of the map, so that terminals with low memory configuration can also use the map.

In addition, the memory may include a high-speed random access memory, and may also include a non-transient memory, such as at least one disk storage device, a flash memory device, or other non-transient solid-state storage device.

Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.
