Description

Technical Field

[0001] The present invention relates to the technical field of equipment information monitoring and projection, and in particular to an instrument information projection method and a system supporting long-distance prompting of instrument status. Background Art

[0002] In modern medical laboratories, testing departments, and various analytical testing sites, it is often necessary to form an enclosed layout within a limited space to accommodate multiple rows of testing and analysis instruments with different functional uses and / or dimensions. These instruments are indispensable tools for scientific research, medical testing, and other activities. The enclosed space layout not only helps to improve the efficiency of space use, but also facilitates management and operation by technicians. In this environment, each instrument has a specific task, and together they form an efficient testing network.

[0003] In the prior art, these testing and analysis instruments are usually equipped with indicator lights, which visually indicate the operating status of the instrument through different colors and modes of light emission. For example, green usually indicates that the instrument is operating normally, yellow indicates that user intervention may be required, and red usually indicates that there is some kind of fault or error in the instrument.

[0004] However, although this light-emitting status prompt function provides basic operating information, it often has certain limitations. For example, in the green light state, although it indicates that the instrument is operating normally, the user cannot know the specific operating progress or detailed status of the instrument, such as the current temperature, pressure and other parameter information; when the prompt light is in a flashing state, although it can inform the user that the instrument needs to add materials or other forms of intervention, the specific amount of remaining materials or the specific content of the required intervention is not clear. To understand the specific information, the operator needs to go to the display device of the instrument in person to check, which may cause time delays. Similarly, when the red light flashes to indicate a fault, although it can prompt the operator that there is a problem with the instrument, the specific cause of the fault is still unknown, and personnel still need to go to check, which will undoubtedly affect the efficiency and timeliness of troubleshooting. Therefore, the existing prompt light system is insufficient in providing detailed information and improving operational efficiency. Summary of the invention

[0005] The main purpose of the present invention is to provide an instrument information projection method and a system supporting the method, aiming to achieve long-distance projection of the in-depth operating condition information of the instrument so that relevant personnel can intuitively view the operating status of the instrument.

[0006] To achieve the above object, the instrument information projection method proposed by the present invention includes:

[0007] Obtain the operating condition information of the instrument;

[0008] generating a projection image according to the operating condition information;

[0009] The projection image is projected onto a target projection area. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The instrument information projection method proposed in the present invention can be found in Figure 1 ,include:

[0035] Obtain the operating condition information of the instrument;

[0036] generating a projection image according to the operating condition information;

[0037] The projection image is projected onto a target projection area.

[0038] Step S10: Obtaining the operating condition information of the instrument.

[0039] It should be noted that, in an embodiment of implementing the above method, the execution subject can be an information projection device with data processing, network communication, program running and projection functions, and can also be equipped with a traditional projector configured with a control module such as data reception and information format conversion and a projection module. This embodiment and the following embodiments are described using an information projection device as an example.

[0040] It is understandable that the instrument can be an IVD analyzer, such as a blood cell analyzer, a biochemical analyzer, a coagulation analyzer, a urine analyzer, an immunoassay analyzer, a mass spectrometer, a blood cell analyzer, etc., and combinations thereof (such as online, assembly lines, a collection of laboratory instruments, etc.), or it can be an instrument or machine involved in a production workshop or a manufacturing workshop. Such instruments often require human intervention in the work process during operation to ensure that the instrument can successfully complete the entire workflow.

[0041] It should be understood that the operating condition information includes various information generated by the instrument during production, such as the identity information of the instrument, the material consumption information of the instrument, the time for loading the instrument, the temperature and pressure of the instrument, and other information that the user wants to know, such as the specific step information in a workflow, the instrument operation time information, etc., and the operating condition information is not limited here; specifically, in one embodiment, taking a blood analyzer as an example, the operating condition information of the instrument includes identity information, operation information, safety information and alarm information. The identity information includes the name, model, production date and precautions of the instrument, etc., and the operating condition information includes the following information: The information includes sample volume, reagent volume, reagent consumption progress, process nodes, etc. Safety information includes component life, light intensity, cleanliness, etc. that may affect detection accuracy. Alarm information includes abnormal test results, process reminders, structural damage / fault information, and sample / reagent abnormality information. For example, structural damage / fault information refers to information that a system has abnormal operation during the operation of the blood analyzer; sample / reagent abnormality information includes clots, high blood lipids, abnormal cell composition (mainly the ratio of white blood cells, red blood cells and platelets), etc., indicating quality problems or potential pathological conditions of the sample. Among them, when the alarm information appears, the information projection device can only project the alarm information and the name of the instrument and equipment according to the preset program, so that the maintenance personnel can respond to the key information in the first time; of course, it is also possible not to hide the operation information and safety information and other information. In this way, when the instrument is suspended, the information projection device still projects these operating condition information, which is convenient for the relevant staff to record the relevant data and prevent information errors after the instrument is suspended; it can be understood that when the instrument generates an alarm message, it can trigger the instrument's sound device to emit an auditory alarm sound, and the instrument's prompt light flashes in the alarm state. The information projection device can enlarge the screen size of the alarm message according to the preset built-in program, and change the screen color to a visually more eye-catching alarm color (such as fluorescent color, red), thereby enhancing the alarm effect of the alarm message.

[0042] In a specific implementation, the information projection device can achieve communication connection with the instrument through a wired connection or a wireless connection to complete data transmission. Specifically, the information projection device can be connected to the instrument through a DisplayPort cable or an HDMI (High Definition Multimedia Interface) cable to achieve data transmission between the two.

[0043] In another embodiment, the information projection device is wirelessly connected to the instrument. Specifically, the information projection device can be connected to the instrument through wireless connection means such as a Bluetooth module and a WIFI module to enable the information projection device to communicate with the instrument and realize data transmission between the two.

[0044] Step S20: generating a projection image according to the operating condition information.

[0045] It should be understood that the presentation forms of projection images include but are not limited to graphics, charts, text, videos, 3D projections, etc., and any combination of these forms. Projection images can intuitively display the current status and performance of the instrument so that users can quickly grasp the operation status of the instrument.

[0046] In one embodiment, after the information projection device receives the operating condition information of the instrument through a communication connection, it can convert the operating condition information into a projection image through a processor. The display method of the projection image can be a partitioned display method of information type or a dynamic scrolling display method. The specific method is explained below.

[0047] Step S40: projecting the projection image onto a target projection area.

[0048] It can be understood that the instrument is usually located in a venue. In one embodiment, the instrument and the information projection device are both located in a detection room consisting of four side walls, a top wall (ceiling) and the ground, and any surface of the detection room can be a projection surface; in another embodiment, the instrument and the information projection device are located in an open space consisting of two opposite side walls, a top wall (ceiling) and the ground, and any surface of the open space can be a projection surface. It can be seen that there is at least one projection surface in the venue that can carry the projection image. The form of the venue is not limited, and the projection performance of the information projection device can be determined according to the light characteristics of the venue such as the light brightness and light duration.

[0049] It should be explained that the target projection area can be any area of ​​the projection surface or a specific area. Specifically, in one embodiment, the user can adjust the projection angle of the information projection device according to his or her own behavior, and the final imaging area on the projection surface is the target projection area. The user's own behavior can be the user's head raising angle, the user's head tilting movement, the user's usual position, etc. An area on the projection surface is selected by visual judgment, and the area is the target projection area; in another embodiment, before each projection of the image, any area on the projection surface can be selected, and the arbitrary area projected each time can be the same or different. At this time, the area finally used for imaging is the target projection area; in another implementation, the information projection device pre-performs an information detection on the projection surface, and determines an area suitable for imaging based on the information detection result.

[0050] As described above, in the technical concept of the present invention, the ultimate goal is to enable the operating condition information of the instrument to be viewed by the user at a long distance. The user does not need to go to the human-computer interaction position of the instrument to view the required information first, and then formulate an interference strategy based on the information. In this way, the user's ability to understand the operating condition information of the instrument in real time can be greatly improved, and the efficiency of proposing solutions to the working problems of the instrument can be greatly improved. At the same time, the information exchange ability at the same level can be improved, thereby ultimately improving the fluency and timeliness of the instrument to complete a single workflow.

[0051] In one embodiment of the present invention, see Figure 2 , step S40, comprising:

[0052] Step S410: determining a projection direction, and determining a projection surface in the projection direction;

[0053] It should be explained that the projection direction can be determined by manually selecting a desired direction. For example, in one embodiment, the upward projection is manually selected, and the projection module of the information projection device faces the ceiling of the environment where the instrument is located. At this time, the ceiling is the determined projection surface. The projection direction can be determined based on factors such as the optical performance of the environment, the distance of the instrument relative to any projection surface to be selected, the area of ​​the projection surface to be selected, whether there are light obstructions on the path between the projection surface to be selected and the instrument, and whether there are objects on the projection surface to be selected. The projection direction can be adaptively selected according to the actual situation of the user; in another embodiment, the selection of the projection direction can be a fixed direction, such as fixed upward projection to the ceiling, or projection to any neat surface; in another embodiment, the information projection device can emit a laser beam to collect surface information of all surfaces to be projected, and determine a projection surface based on the surface information results.

[0054] In the above, there is no restriction on the determination of the projection surface.

[0055] Step S420: acquiring detection information of the detection light on the area to be projected on the projection surface, and judging whether the area to be projected is a target projection area according to the detection information result;

[0056] It needs to be explained that after determining the projection surface, a target projection area still needs to be determined. In order to make the target projection area more conducive to imaging, the information projection device needs to detect all areas of the projection surface. Before determining the target projection area, all detected areas on the projection surface can be the so-called "area to be projected". Whether the area to be projected is the target projection area is determined based on the final detection information results. The detection information may include obstacle information of the light path, light characteristic information of the area, surface flatness information, and area information, etc. A comparison result is generated by comparing these detection information with a comparison threshold preset by the information projection device to determine whether the area to be projected is the target projection area.

[0057] Step S430: If yes, project the projection image onto the target projection area.

[0058] After determining the target projection area, the information projection device projects the projection image onto the target projection area. It should be explained that, because the target projection area is subject to change, in one embodiment, the information projection device includes a pan-tilt head and a projection device body, and the projection lens of the information projection device is rotated under the control of a motor, thereby realizing the function of determining the target projection area.

[0059] In one embodiment of the present invention, the step S420 of acquiring detection information of the detection light on the area to be projected on the projection surface includes:

[0060] Step S4201: controlling the detection light to project onto the projection surface to obtain projection information;

[0061] Step S4202: Meshing the projection surface according to the projection information to obtain an area to be projected;

[0062] Step S4203: Acquire the flatness information of the area to be projected, where the flatness information is the detection information.

[0063] Specifically, the detection light is controlled to project on the area to be projected on the projection surface to obtain a projection result, that is, the projection module can emit a detection light to the projection surface. The detection light can be a light without operating condition information or a light with operating condition information, which is not limited here. At the same time, it needs to be explained that because the system that supports long-distance prompting of the instrument status is in a working environment with a relatively fixed spatial volume, based on this, the user should know the length, width, and height of the spatial volume, that is, the three-dimensional size of the building is not a variable, and can be obtained by measuring or checking the architectural data of the building, so as to know the total area of ​​the projection surface. After determining the minimum distance between the information projection device and the projection surface, the area of ​​the projection image can be determined by debugging the projection parameters such as the lens focal length and projection ratio of the information projection device (if the projection image is a 3D holographic projection, the area of ​​the maximum cross-section of the 3D holographic projection can be determined), so as to determine the ratio of the area of ​​the projection image to the area of ​​the projection surface. According to the area ratio, the information projection device divides the projection surface into a plurality of areas to be projected that meet the area ratio, and the number of areas to be projected is proportional to the area of ​​the projection surface. The product of the areas of the projection images is the area of ​​the projection surface, or the product of the number of areas to be projected, the area of ​​the projection images, and the preset weight parameters is the area of ​​the projection surface. This is not limited here and can be specifically set according to the accuracy requirements. Then, the area to be projected that is closest to the information projection device (i.e., the straight-line distance from the center point of each area to be projected to the information projection device) can be selected for flatness detection. Of course, the area to be projected can be selected based on the position information of at least one user relative to the instrument, and the flatness information obtained by the detection is used as the required detection information, so as to determine whether the detected area to be projected is the required target projection area; in one embodiment, after the detection light is projected on the projection surface to determine the required area to be projected, the area to be projected is divided equally, that is, one area to be projected is divided into N sub-detection areas of equal area, wherein, considering that the area to be projected is not a plane in an ideal state, the equal area at this time refers to the ideal boundary of the sub-detection area (if the shape of the sub-detection area is a square, the ideal boundary is the length and width of the projection of the sub-detection area on an ideal plane, and the length and width are both straight lines with a flatness of;Similarly, if the shape of the sub-detection area is circular, the boundary is the radius of the sub-detection area, and the radius is an area enclosed by a straight line with a flatness of . Then, the detection light detects the center of each sub-detection area, and the distance from the detection light to the central sub-detection area in the area to be projected is used as a reference value. According to the number of divisions, the angle required for the detection light to deviate from the central sub-detection area to the remaining sub-detection areas surrounding the central sub-detection area can be known. According to the deviation angle and the reference value, the theoretical distance from the detection light to the center of each sub-detection area can be calculated, and the difference between the theoretical distance and the actual distance of each sub-detection area can be obtained. At the same time, the limit difference can be preset according to the deviation angle. If the difference of each sub-detection is within the corresponding limit difference, the projection area can be considered as the target projection area. Further, considering the deformation amount of the projection surface to improve the accuracy of information detection, the closer each sub-detection area is to the center of the projection surface, the smaller the limit difference. ;

[0064] In another embodiment of the present invention, please refer to Figure 3 , the step S4203 of obtaining the flatness information of the area to be projected includes:

[0065] Step S42031: Obtain the area center point P1 of the area to be projected;

[0066] Step S42032: Generate an actual projection line L with the center point P1 of the area as the midpoint in the area to be projected, and generate a plurality of grid calibration points P2 to P3 based on the actual projection line L. n ;

[0067] Step S42033: Generate a reference straight line L with the center point P1 of the region as the midpoint th , according to the reference straight line L th Generate multiple theoretical reference points P th2 To P thn ;

[0068] Step S42034: Calculate each of the grid calibration points P2 to P n The corresponding theoretical reference point P th2 To P thn The spacing value between them is used as detection information.

[0069] Specifically, the detection light is driven to project the area to be projected on the projection surface to obtain the projection result, the area to be projected is grid-divided to obtain the area center point P1, and the actual projection line L with the area center point P1 as the midpoint is obtained. The actual projection line L is any line in the area to be projected. For example, when the area to be projected is a square, the actual projection line L can be a straight line such as a diagonal line and a central axis, or a curve, and the curve only needs to have the area center point P1 as the midpoint; when the area to be projected is a circle, the actual projection line L can be a diameter passing through the center of the circle, or a curve passing through the center of the circle, and the curve only needs to have the area center point P1 as the midpoint; then, a plurality of grid calibration points P2 to P3 are generated according to the actual projection line L. n , where the grid calibration points P2 to P n The actual projection line L can be divided into multiple points of equal length, and the specific number of grid calibration points is not limited here.

[0070] Generate a reference straight line L with the center point P1 of the area as the midpoint th , according to the reference straight line L th Generate multiple theoretical reference points P th2 To P thn , reference straight line L th is the projection line of the actual projection line L on a reference plane parallel to the horizontal plane where the center point P1 of the region is located. Thus, the grid calibration points P2 to P on the actual projection line L n Match the reference straight line L one by one th The theoretical reference point P th2 To P thn .

[0071] Then, calculate each of the grid calibration points P2 to P n The corresponding theoretical reference point P th2 To P thn If each spacing value of the area to be projected is less than the preset spacing threshold, the information projection device can determine that the area to be projected is the target projection area. If there is a spacing value in the area to be projected that is greater than the preset spacing threshold, the second area to be projected is selected, and the second area to be projected is the second straight-line distance from the center point of the area to be projected to the information projection device.

[0072] If each spacing value of the area to be projected is less than the preset spacing threshold, the information projection device can identify the area to be projected as the target projection area. Specifically, when the theoretical reference point P is determined th2 To P thn After that, a parallel and equal-length reference line L can be determined. thThe threshold reference line is a threshold reference line, and the distance between the threshold reference line and the theoretical reference line is a preset distance threshold. In this way, the threshold reference line has a threshold reference point P corresponding to the theoretical reference point one by one. 阈值2 To P 阈值n At this time, the information projection device is moved to the grid calibration point P2 and the theoretical reference point P th2 A straight line can be formed. The straight line from the information projection device to the grid calibration point P2 is L1, and the straight line from the information projection device to the theoretical reference point P th2 The straight line is L2, the angle α1 between L2 and L1 is obtained, and the theoretical reference point P is calculated according to the geometric relationship between L1, L2 and α1. th2 and the grid calibration point P2, if each theoretical distance is less than the preset distance threshold, then the area to be projected can be identified as the target projection area, and then the projection image is set in the target projection area; if there is a theoretical distance less than the preset corresponding distance threshold, the area to be projected is adjusted; specifically, in one embodiment, taking the projection surface as the ceiling as an example, combined with Fig.10 As shown, the projection information device has a distance measuring module, and the distance from the projection information device to the detection point is obtained through the distance detection medium (such as laser, ultrasonic wave) emitted by the distance measuring module. The distance measuring module and the projection module are integrated in the device housing and are uniformly controlled by the control module of the projection information device. When the projection information device captures the actual projection line L through a preset program, the control system randomly captures any multiple points P2 to P on the actual projection line L through a preset program. n As the grid calibration point, the distance detection is then performed. The specific process is as follows:

[0073] Step 1: Obtain the straight-line distance l from the projection information device to point P1 and the angle α1 between the straight-line distance l and the vertical line from the projection information device to the ceiling;

[0074] It should be explained that P1 is a real point on the ceiling, so the straight-line distance l1 to point P1 obtained by the ranging module is a real value; at the same time, the projection information device has an initial state and multiple distance detection states. In the initial state, the emission angle of the ranging module is vertically pointed to the projection surface (in this embodiment, vertically pointed to the ceiling). When point P1 needs to be detected, it enters the first distance detection state. In the first distance detection state, the ranging module is rotated so that the emission angle of the ranging module is linearly pointed to P1. At this time, the emission angle of the ranging module is α1, that is, the angle α1 between the straight-line distance l and the vertical line from the projection information device to the ceiling. In this case, through the spatial geometric relationship, the control module can calculate the vertical straight line distance H from the projection information device to point P1, and it can be understood that because the reference straight line L th It is a projection line based on point P1, so the projection information device is placed on the reference line L thThe vertical distance is H;

[0075] Step 2: Based on H, the line length and angle α2 from the information projection device to P2 are obtained, thereby obtaining H2;

[0076] It should be explained that P2 is a real point on the ceiling. Therefore, the straight-line distance l2 obtained by the ranging module to point P2 is a real value. At this time, in the second distance detection state, the emission angle of the ranging module points to P2. At this time, the emission angle of the ranging module is α2, that is, the angle α2 between the straight-line distance l2 and the vertical line from the projection information device to the ceiling. In this case, through the spatial geometric relationship, the control module can calculate the vertical straight-line distance H2 from the projection information device to point P2. At the same time, because the reference straight line L th is a projection line based on point P1, point P2 and the corresponding P th2点 The theoretical distance between them is the absolute value of H2 and H;

[0077] Step 3: Compare point P2 with the corresponding P th2 The absolute value between point P2 and the threshold reference point P 阈值2 The absolute value between .

[0078] It needs to be explained that the network calibration point P on the actual projection line L is th There are three situations in the upper and lower positions of the corresponding theoretical reference point P: (i) the network calibration point P is located above the corresponding theoretical reference point P; (ii) the network calibration point P is located below the corresponding theoretical reference point P; (iii) the network calibration point P and the corresponding theoretical reference point P overlap flush. Therefore, we can further derive a reference straight line L th Under the same threshold standard, there are two threshold reference lines in upper and lower directions. In order to facilitate comparison, the absolute value concept is used for comparison.

[0079] It can be understood that in the above three steps, only one network calibration point P2 on the actual projection line L is detected and determined. Based on what is mentioned, the information projection device can detect and determine any number of network calibration points P captured according to a preset program, so as to determine whether the area to be projected meets the requirements to become the target projection area.

[0080] It is further necessary to explain that the technical concept contained in the present technical solution is mainly to realize the detection based on flatness information so as to judge whether the area to be projected meets the requirements to become the target projection area. Therefore, the accuracy problems that may arise in this case are not considered for the time being. The accuracy problem belongs to the problem to be solved that goes beyond the present technical concept and requires further technical improvement. Therefore, no excessive explanation will be given in this application.

[0081] In one embodiment of the present invention, see Figure 4 , before the step of projecting the projection image onto the target projection area in step S430, it also includes:

[0082] Step S50: determining the area of ​​the target projection area;

[0083] Step S60: obtaining a ratio between an area of ​​the projection image and an area of ​​the target projection region, and determining a projection mode of the projection image according to the area ratio.

[0084] Specifically, after the information projection device divides the projection surface into grids, the area of ​​each grid can be known through the specific number of grids, thereby knowing the area of ​​the target projection area. In one embodiment, when the area of ​​the projected image is much smaller than the area of ​​the projection area, partitioned projection can be adopted, that is, the operating condition information is divided into different types of sub-information, and each sub-area of ​​the projection area is used to carry a sub-information part of the operating condition information. In this way, the user's information query convenience and the neatness and orderliness of information projection can be improved; in another embodiment, when the area of ​​the projection area is small, a dynamic projection method (i.e., image scrolling) can be adopted, and the first sub-information part of the operating condition information is projected in the first time period, and then the second sub-information part of the operating condition information is projected in the second time period, and multiple time periods are alternately cycled in sequence.

[0085] In one embodiment of the present invention, see Figure 5 The step S60 of determining the projection mode of the projection image according to the area ratio further includes:

[0086] Step S610: If the area ratio is greater than the theoretical preset ratio of the projection image, the projection mode is dynamic projection;

[0087] Step S620: If the area ratio is smaller than the theoretical preset ratio of the projection image, the projection method is partition projection.

[0088] It should be explained that the information projection device can preset a theoretical preset ratio of 1:4. If the area of ​​the target projection area is less than four times the area of ​​the projection image, the information projection device can be manually adjusted to enlarge the area of ​​the projection image. At this time, dynamic projection can be adopted, that is, different operating condition information is displayed in different time periods, thereby improving the clarity of the information; if the area of ​​the target projection area is four times or more than the area of ​​the projection image, at this time, it can be indicated that the area of ​​the target projection area is much larger than the area of ​​the projection image. The information projection device can be manually adjusted to enlarge the area of ​​the projection image. At this time, the projection image is divided into multiple sub-images containing one type of operating condition information, and each sub-image is projected into the target projection area to form multiple sub-display areas, thereby improving the comprehensiveness of the information.

[0089] In one embodiment of the present invention, see Figure 1 , before the step of obtaining the detection information of the detection light on the to-be-projected area of ​​the projection surface in step S420, it also includes:

[0090] Step S30: establishing an absolute spatial coordinate system with the instrument or information projection device as the coordinate origin, obtaining spatial position information of at least one user relative to the instrument, and establishing a two-dimensional spatial model according to the spatial position information;

[0091] Step S31: Calculate the central area of ​​the two-dimensional space model relative to the projection surface and mark it as the area to be projected.

[0092] It can be understood that the technical solution included in this embodiment is to determine an area to be projected with the highest detection priority. After the area to be projected is determined as a target projection area through information detection, the target projection area makes it convenient for multiple users to easily view the projected image at their respective positions, avoiding the target projection area being too close to a certain user and too far from another user, thereby avoiding a certain user from being unable to see a certain working condition information.

[0093] Specifically, the information projection device scans the space of the environment in which the device is located, and establishes an absolute space coordinate system including an X-axis, a Y-axis, and a Z-axis. In this embodiment, Fig.11 As shown, the absolute space coordinate system takes the instrument as the coordinate origin (0, 0, 0), obtains the spatial position information of multiple users relative to the instrument, and in the absolute space coordinate system, there are 3 users at different positions, and obtains the spatial position information of each user in the absolute space coordinate system, such as (X1, Y1, Z0), (X2, Y2, Z0) and (X3, Y3, Z0). A triangular two-dimensional space model is generated with these three spatial position information. When the two-dimensional space model is projected on the projection surface, the Z0 coordinate becomes a ceiling with the Z-axis limit value Z 极限 At this time, the two-dimensional space model has a center (i.e., the center of the triangle) on the projection surface, and the grid where the center is located is selected as the center area. At this time, the center area is marked as the area to be projected, and then the information projection device performs the above information detection on the area to be projected; in another embodiment, please combine Fig.11 As shown, in the absolute space coordinate system, there are 4 users in different positions, and a two-dimensional space model in the shape of a quadrilateral established with the space coordinates of the 4 users as vertices is obtained. Referring to the method in the previous embodiment, the center of the two-dimensional space model in the shape of a quadrilateral projected on the projection surface is obtained, thereby obtaining the area to be projected; it can be understood that an absolute space coordinate system can also be established with the information projection device as the coordinate origin. The two are just changes in reference values, and no repeated explanation is given here.

[0094] In one embodiment of the present invention, see Figure 6 , step S30, comprising:

[0095] Step S310: establishing an absolute space coordinate system with the instrument as the coordinate origin, and obtaining spatial position information of at least one user relative to the instrument;

[0096] Step S320: Generate the actual coordinate interval (X1, X2, ..., X2) of the user in the absolute space coordinate system according to the spatial position information. n , Y1, Y2...Y n ), and determine the actual coordinate intervals (X1, X2...X n , Y1, Y2...Y n ) of the reference coordinate center (X c , Y c );

[0097] Step S330: Based on the reference coordinate center (X c , Y c )Build a two-dimensional space model.

[0098] In this embodiment, considering that each user may be in an active state, the information projection device obtains the spatial position information of each user relative to the instrument within a time period. At this time, the spatial position information of each user is recorded and an actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ), the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ) The image generated can be circular or polygonal, which is not limited here, and then the actual coordinate intervals (X1, X2...X n , Y1, Y2...Y n ) of the reference coordinate center (X c , Y c ), at this time, each user reference coordinate center (X c , Y c ) can be the initial value of the user in the absolute space coordinate system, or not, and the relationship between the two is determined according to the user's activity trajectory; when obtaining the reference coordinate center (X c , Y c ), the two-dimensional space model is generated according to the above method, and no repeated explanation is given here; it can be understood that how to obtain (X1, X2...X n , Y1, Y2...Y n ) of the reference coordinate center (X c , Y c) involves technical means such as image generation, image analysis and image calculation. These technical means involve the problem of position accuracy, which has exceeded the present technical concept and requires further technical improvement to be solved. Therefore, in this application, no excessive explanation is given. You can refer to the existing technology and no unnecessary explanation is given here.

[0099] In one embodiment of the present invention, see Figure 7 , step S320, further comprising:

[0100] Step S3201: Based on the reference coordinate center (X c , Y c ) generates the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ), the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ) is larger than the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n )

[0101] Step S3202: Obtain the user's real-time position to generate real-time coordinate information relative to the instrument (X rt , Y rt ), determine the real-time coordinate information (X rt , Y rt ) is located in the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t )Inside;

[0102] Step S3203: If not, generate the real-time coordinate information (X rt , Y rt ) as the first boundary, with the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ) relative to the real-time coordinate information (X rt , Y rt )Adjustment coordinate information of the maximum linear distance (X ad , Y ad ) is the second boundary, generating a dynamic interval (X di1 , X di2 ...X din , Y di1 , Y di2 ...Y din ), according to the dynamic interval (X di1 , X di2 ...X din , Y di1, Y di2 ...Y din ) generates real-time center coordinates, generates a dynamic two-dimensional space model according to the real-time center coordinates, and redefines the target projection area.

[0103] Furthermore, considering that the user's activity range within a period of time is too large, it is necessary to determine whether the target projection area needs to be adjusted according to the user's real-time position. In one embodiment, based on the reference coordinate center (X c , Y c ) generates the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ), the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ) is larger than the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ) range, it can be understood that the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ) must at least cover the entire actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ), wherein the information projection device can collect the same time of any number of days for each user to determine the user's motion trajectory, motion range and other motion information, and generate a theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ), detect the user's actual coordinates in real time and determine whether the actual coordinates are within the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t )middle.

[0104] It should be explained that if the actual coordinates of one or more users are not within the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ), at this time, the real-time coordinate information (X rt , Y rt ) as the first boundary, with the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ) relative to the real-time coordinate information (X rt , Y rt )Adjustment coordinate information of the maximum linear distance (X ad , Y ad ) is the second boundary, generating a dynamic interval (Xdi1 , X di2 ...X din , Y di1 , Y di2 ...Y din ), where “first boundary” and “second boundary” refer to the dynamic range (X di1 , X di2 ...X din , Y di1 , Y di2 ...Y din ) is the two points that are farthest apart in the image formed by the real-time coordinate information (X rt , Y rt ) and adjust the coordinate information (X ad , Y ad ) is a straight line formed by the endpoints, which scans the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ), at this time, the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ) There are two or more tangent points or contour lines that can identify the straight line sweeping in and out, such as Fig.12 and Fig.13 As shown, connect the real-time coordinate information (X rt , Y rt ) and the tangent point or contour line to form a new figure, which is consistent with the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ) is the dynamic range (X di1 , X di2 ...X din , Y di1 , Y di2 ...Y din )

[0105] Get dynamic range (X di1 , X di2 ...X din , Y di1 , Y di2 ...Y din ) of the reference coordinate center (X c , Y c ) generates a dynamic two-dimensional space model, and then determines the area to be projected according to the above method, thereby determining the target projection area.

[0106] In one embodiment of the present invention, see Figure 8After the step of generating a dynamic two-dimensional space model according to the real-time center coordinates and re-determining the target projection area in step S3203, the method further includes:

[0107] Step S3204: if not, obtaining detection information of a preset deviation center area of ​​the dynamic two-dimensional space model relative to the projection surface;

[0108] Step S3205: Determine whether the preset off-center area is the target projection area according to the detection information result.

[0109] In one embodiment, the re-determined area to be projected still needs to determine its flatness information detection result, and the information detection method adopts the method explained above, which will not be repeated here;

[0110] If the projection area obtained by the dynamic two-dimensional space model cannot be used as the target projection area according to the information detection result, the coordinate information (X ad , Y ad ) is located at the real-time coordinate information (X rt , Y rt ), the position of the projection area is shifted by a preset unit to obtain a new projection area, which is the preset deviation from the center area. The X-axis and Y-axis can be used as the reference system to determine the adjustment coordinate information (X ad , Y ad ) is located at the real-time coordinate information (X rt , Y rt ) is not limited here, such as adjusting the coordinate information (X ad , Y ad ) is located at the real-time coordinate information (X rt , Y rt ), the first grid on the left side of the projection area is used as the preset off-center area. Of course, any number of grids can be used as the preset off-center area, which is not limited here;

[0111] The preset off-center area is detected to obtain detection information, and then judged again to obtain the target projection area. The specific judgment method adopts the judgment method explained above, which will not be repeated here; if the preset off-center area obtained for the first time still does not meet the requirements, the above-mentioned method for determining the preset off-center area is used here, and the second preset off-center area is selected here until the target projection area is obtained.

[0112] In one embodiment of the present invention, see Figure 2 , after step S420, further comprising:

[0113] Step S440: If not, obtain detection information of another area to be projected on the projection surface by the detection light, and determine whether the other area to be projected is the target projection area according to the detection information result.

[0114] It should be explained that the detection information of another area to be projected on the projection surface at this time is based on the fact that the first area to be projected has been obtained through all the above embodiments. At this time, because the first area to be projected is not the required target projection area, it is necessary to determine the target projection area twice or more times.

[0115] Specifically, when it is determined that the first area to be projected is not the required target projection area, a second area to be projected is selected, and the center point of the second area to be projected is the minimum value of the center point of the first area to be projected among all areas to be projected (i.e., the areas to be projected formed after the projection surface is gridded). If there are multiple areas to be projected that meet this condition, the one closest to the instrument (i.e., the coordinate origin) is used as the selection condition, thereby selecting the second area to be projected.

[0116] In one embodiment of the present invention, see Fig. 9 , step S10, comprising:

[0117] Step S110: obtaining the user's authority information corresponding to the instrument;

[0118] Step S120: Acquire operating condition information matching the instrument according to the authority information.

[0119] It needs to be explained that in some instruments with confidentiality requirements or different users only need to view one or required operating condition information during different working time periods. At this time, for the sake of information confidentiality or highlighting key information, the user's authority information for the instrument is preset to be identified, and the operating condition information matching the instrument is obtained based on the authority information.

[0120] Specifically, the user's authority information relative to the instrument can be obtained by identifying the user's fingerprint, pupil, face, voice, etc., and the operating condition information matching the instrument can be obtained based on the authority information. In this way, different users can only obtain the operating condition information of their corresponding instruments.

[0121] The system supporting remote prompting of instrument status, such as Fig.14 As shown, including:

[0122] Instruments; and

[0123] An information projection device is communicatively connected to the instrument; the information projection device is configured to obtain operating condition information of the instrument and generate a projection image according to the operating condition information.

[0124] In the technical solution of the present invention, a system supporting long-distance prompting of instrument status includes an instrument and an information projection device. The information projection device is communicatively connected to the instrument so that the information projection device can obtain operating condition information of the instrument. The information projection device generates a projection image based on the operating condition information. The projection image can display the operating status of the instrument. In this way, the user can view the specific operating information of the instrument in detail at a long distance from the instrument, which is convenient for the user to prepare for subsequent interference work in advance and improve work efficiency.

[0125] It is understandable that the instrument can be an IVD analyzer, such as a blood cell analyzer, a biochemical analyzer, a coagulation analyzer, a urine analyzer, an immunoassay analyzer, a mass spectrometer, a blood cell analyzer, etc., and combinations thereof (such as online, assembly line, etc.), or it can be an instrument or machine involved in a production workshop or a manufacturing workshop. Such instruments often require human intervention in the work process during operation to ensure that the instrument can successfully complete the entire workflow.

[0126] In the present technical solution, the information projection device obtains the operating condition information of the instrument, and generates a projection image according to the operating condition information, and the information projection device projects the projection image onto a wall or a white screen in the environment where the instrument is located; in one embodiment, the instrument is located in a testing department, and the information projection device can project the operating condition information of the instrument onto the ceiling or the side wall of the testing department through a communication connection, which is not limited here; in another embodiment, a white screen is provided on the ceiling or the side wall of the testing department, and the location of the white screen is the projection area, and the white screen is used to carry the projection image generated according to the operating condition information to meet the visual experience; based on the above embodiments, it can be objectively concluded that the operating condition information actually required by the user, such as the identity information of the instrument, the material consumption information of the instrument, the waiting time for loading of the instrument, the temperature and pressure of the instrument and other depth information can be displayed at a longer distance of the instrument through the information projection device, thereby improving the user's interference efficiency.

[0127] Based on the two embodiments proposed above, no matter in which embodiment, there is at least one projection area in the laboratory department, and the projection area can be determined manually by the user, such as judging by the naked eye that there is a suitable projection area in a certain area of ​​the ceiling or side wall, or the information projection device can automatically address and determine the projection area.

[0128] Based on how to determine the projection area as described above, the information projection device can be a fixed setting or a movable setting. In one embodiment, after the projection area is manually determined, the information projection device is fixedly set on the instrument so that the projection direction of the instrument is facing the projection area; in another embodiment, the information projection device is movably set, and the projection direction is first determined to obtain the projection bearing surface of the inspection department, such as the ceiling or side wall, and then automatically searches for a suitable projection area on the ceiling or side wall. In this embodiment, the information projection device can be equipped with a pan-tilt head to realize the rotation of the projection lens of the information projection device under the control of a motor, thereby realizing the automatic addressing function. The specific implementation method of the automatic addressing is explained in detail below.

[0129] Further, in one embodiment, if Fig.14 As shown, the system supporting remote prompting of instrument status includes one of the instrument and one of the information projection devices, so that one information projection device can generate required operating condition information about the instrument, thereby reducing system complexity; in another embodiment, the system supporting remote prompting of instrument status includes one of the instrument and multiple information projection devices, each of the information projection devices is configured to obtain different operating condition information of the instrument, wherein each information projection device can obtain a part of the operating condition information of the same instrument, such as, in this embodiment, the operating condition information can be divided into instrument identity information, instrument operation information and operation result information, the instrument identity information includes the manufacturer of the instrument, factory information, instrument model, etc., when the instrument is a biochemical analyzer, the instrument identity information includes sample analysis progress, sample material status, instrument operation information, etc. The operation result information includes sample index information, sample qualification rate, etc. Thus, in this system, one instrument can be equipped with three information projection devices. The specific information classification method can be determined according to the required information, thereby obtaining the required information projection device. Thus, the operation condition information of the instrument can be clearly displayed to avoid information interference. In another embodiment, the system supporting long-distance prompt of instrument status includes a plurality of the instruments and an information projection device. The information projection devices are communicatively connected to the plurality of instruments, and each instrument is communicatively connected to the information projection device. The information projection device includes projection lenses matching the number of instruments, and each lens projects the operation condition information of an instrument. Thus, the space occupied by the information projection device can be reduced, and the difficulty of determining the position and installing the information projection device in the inspection department can be reduced. In another embodiment, if Fig.15As shown, the system supporting remote prompting of instrument status includes a plurality of the instruments and a plurality of the information projection devices, each of the information projection devices is communicatively connected to an instrument, so that an information projection device can project information on an instrument in a targeted manner. Specifically, the system supporting remote prompting of instrument status includes three instruments and three information projection devices, the information projection devices are simultaneously controlled by a control center, and the three instruments can have different working time periods. In a first time period, the first instrument is in a working state, the second instrument is in a ready state, and the third instrument is in a stopped state. The first information projection device projects the operating condition information of the first instrument, and the second information projection device projects the ready state information of the second instrument. The ready state The status information includes but is not limited to specific working hours, specific work content, etc. The third information projection device projects the shutdown information of the third instrument, such as whether the shutdown is due to a fault or not within the specified time period, the last working time, etc. Similarly, the second time period and the third time period are also the same. Of course, the three instruments can work simultaneously in one time period. Each information projection device projects the operating condition information of the corresponding instrument. Based on this, if the projection area is automatically addressed, there are multiple projection areas on the projection surface. In order to avoid interference problems among multiple projection areas, under the control of the control center, the projection areas determined by each instrument avoid each other to avoid overlapping of the projection screen, resulting in unclear projection image display.

[0130] In one embodiment of the present invention, Fig.14 As shown, the information projection device is arranged on the instrument. Specifically, the information projection device can be arranged on the top of the instrument. The projection direction of the information projection device can be upward projection to the ceiling, or can be projection to the side of the instrument. For example, in a testing department, the side projection refers to projecting the projection image onto the side wall in the testing department. In another embodiment, the information projection device is independently arranged on the outside of the instrument. In this way, it is convenient to change the position of the information projection device, to manually determine the projection area or for the information projection device to automatically find a suitable projection area. At the same time, it is convenient to clean the protective glasses of the information projection device, thereby ensuring the clarity of the projection image and the visual effect.

[0131] Further, in one embodiment, the information projection device is provided on the instrument. In this case, the information projection device is wired to the instrument so that the information projection device can be communicatively connected to the instrument. Specifically, the information projection device can be connected to the instrument via a DisplayPort cable or an HDMI (High Definition Multimedia Interface) cable.

[0132] In another embodiment, the information projection device is wirelessly connected to the instrument. Specifically, the information projection device can be connected to the instrument through wireless connection means such as a Bluetooth module and a WIFI module to enable the information projection device to communicate with the instrument and realize output transmission between the two.

[0133] In one embodiment of the present invention, Fig.16 As shown, the information projection device includes an information processing module and a projection module. The information processing module is configured to generate a projection image according to the operating condition information of the instrument; and the projection module is configured to project the projection image.

[0134] In this embodiment, the information projection device mainly includes an information processing module and a projection module. The information processing module is used to collect and analyze the operating condition information of the instrument, such as the sensor data, performance parameters and fault diagnosis results of the instrument, and the information processing module can convert these data into projection images. The forms of projection images include but are not limited to graphics, charts, texts, videos and 3D projections, etc. These projection images can intuitively display the current status and performance of the instrument so that users can quickly grasp the operation of the instrument; the projection module is used to project the image generated by the information processing module onto a wall, screen or other plane. The projection module can use different projection technologies such as DLP, LCD or laser to ensure the clarity and brightness of the projection image. In addition, the module also allows users to adjust the size, brightness and contrast of the image as needed to adapt to different projection environments, match the brightness of light in the projection environment, the brightness of light at different times, etc.

[0135] Furthermore, if Fig.14 As shown, in order to improve the convenience of the system supporting the remote prompt of the instrument status, the information projection device further includes an addressing module, the addressing module is configured to determine a projection area, the projection module projects the projection image on the projection area, specifically, after determining the projection surface of the projection module, the addressing module can determine the position of the projection area according to the flatness information of the projection surface, wherein the flatness determination of the projection surface includes the following methods:

[0136] Determine a projection direction, and determine a projection surface in the projection direction;

[0137] Driving the detection light to project the to-be-projected area of ​​the projection surface to obtain a projection result;

[0138] According to the projection result, the area to be projected is meshed to obtain the area center point P1, and an actual projection line L with the area center point P1 as the center point is obtained. According to the actual projection line L, a plurality of grid calibration points P2 to P n ;

[0139] Generate a reference straight line L with the center point P1 of the region as the center point th , according to the reference straight line L th Generate multiple theoretical reference points P th2 To P thn ;

[0140] Calculate each of the grid calibration points P2 to P n The corresponding theoretical reference point P th2 To P thn The spacing value between them, each of the spacing values ​​is used as detection information;

[0141] Determine whether the area to be projected is a target projection area according to the detection information result;

[0142] If yes, the projection pattern is projected onto the target projection area.

[0143] Among them, the detection light is driven to project the to-be-projected area of ​​the projection surface to obtain the projection result, that is, the projection module can emit a detection light to the projection surface, and the detection light can be a light without operating condition information or a light with operating condition information, which is not limited here. At the same time, it needs to be explained that because the system that supports long-distance prompts of instrument status is in a working environment with a relatively fixed spatial volume, based on this, the user should know the length, width, and height of the spatial volume, and know the total area of ​​the projection surface. After determining the minimum distance between the information projection device and the projection surface, the area of ​​the projection image can be determined by debugging the projection parameters such as the lens focal length and projection ratio of the information projection device (if the projection image is a 3D holographic projection The area of ​​the maximum cross section of the 3D holographic projection can be determined, thereby determining the ratio of the area of ​​the projection image to the area of ​​the projection surface. According to the area ratio, the information projection device divides the projection surface into a plurality of to-be-projected areas that meet the area ratio. The product of the number of to-be-projected areas and the area of ​​the projection image is the area of ​​the projection surface, or the product of the number of to-be-projected areas, the area of ​​the projection image, and a preset weight parameter is the area of ​​the projection surface. This is not limited here and can be specifically set according to the accuracy requirements. Subsequently, the to-be-projected area closest to the information projection device (i.e., the straight-line distance from the center point of each to-be-projected area to the information projection device) can be selected for flatness detection, or the to-be-projected area can be selected according to the position information of at least one user relative to the instrument.

[0144] After determining the area to be projected, the area to be projected is grid-divided to obtain the area center point P1, and an actual projection line L with the area center point P1 as the center point is obtained. The actual projection line L is any line in the area to be projected. For example, when the area to be projected is a square, the actual projection line L can be a straight line such as a diagonal line or a central axis, or a curve, and the curve only needs to have the area center point P1 as the midpoint; when the area to be projected is a circle, the actual projection line L can be a diameter passing through the center of the circle, or a curve passing through the center of the circle, and the curve only needs to have the area center point P1 as the midpoint; then, a plurality of grid calibration points P2 to P3 are generated according to the actual projection line L. n , where the grid calibration points P2 to P n The actual projection line L can be divided into multiple points of equal length, and the specific number of grid calibration points is not limited here.

[0145] Generate a reference straight line L with the center point P1 of the area as the midpoint th , according to the reference straight line L th Generate multiple theoretical reference points P th2 To P thn , reference straight line L th is the projection line of the actual projection line L on a reference plane parallel to the horizontal plane where the center point P1 of the region is located. Thus, the grid calibration points P2 to P on the actual projection line L n Match the reference straight line L one by one th The theoretical reference point P th2 To P thn .

[0146] Then, calculate each of the grid calibration points P2 to P n The corresponding theoretical reference point P th2 To P thn If each spacing value of the area to be projected is less than the preset spacing threshold, the information projection device can determine that the area to be projected is the target projection area. If there is a spacing value in the area to be projected that is greater than the preset spacing threshold, the second area to be projected is selected, and the second area to be projected is the second straight-line distance from the center point of the area to be projected to the information projection device.

[0147] If each spacing value of the area to be projected is less than the preset spacing threshold, the information projection device can identify the area to be projected as the target projection area. Specifically, when the theoretical reference point P is determined th2 To P thn After that, a parallel and equal-length reference line L can be determined. th The threshold reference line is a threshold reference line, and the distance between the threshold reference line and the theoretical reference line is a preset distance threshold. In this way, the threshold reference line has a threshold reference point P corresponding to the theoretical reference point one by one. 阈值2To P 阈值n At this time, the information projection device is moved to the grid calibration point P2 and the theoretical reference point P th2 A straight line can be formed. The straight line from the information projection device to the grid calibration point P2 is L1, and the straight line from the information projection device to the theoretical reference point P th2 The straight line is L2, the angle α1 between L2 and L1 is obtained, and the theoretical reference point P is calculated according to the geometric relationship between L1, L2 and α1. th2 and the theoretical distance between the grid calibration point P2. If each theoretical distance is less than the preset distance threshold, the area to be projected can be identified as the target projection area, and the projection image is then set within the target projection area; if there is a theoretical distance that is less than the preset corresponding distance threshold, the area to be projected is adjusted.

[0148] Based on the above technical solution, the projection method of the projection image of the information projection device is not set. For example, when the area of ​​the projection image is the same as the area of ​​the projection area, partition projection can be adopted, that is, the operating condition information is divided into different types of sub-information, and each sub-area of ​​the projection area is used to carry a sub-information part of the operating condition information. In this way, the user's information query convenience and the neatness and orderliness of information projection can be improved; when the area of ​​the projection area is small, a dynamic projection method (i.e., image scrolling) can be adopted to project the first sub-information part of the operating condition information within a certain time period, and then project the second sub-information part of the operating condition information within a second time period, and multiple time periods are alternately cycled in sequence.

[0149] In one embodiment of the present invention, Fig.16 As shown, the information projection device further includes a position acquisition module, which is configured to acquire position change information of the user relative to the instrument, and the addressing module redetermines the projection area according to the position change information.

[0150] It needs to be explained that when the information projection device detects that the user's position relative to the instrument has changed within a preset time, the position acquisition module collects the user's position change information. It may also be that there are personnel changes in the department's testing work, and the projection area needs to be updated regularly, or the user may actively trigger the update of the projection area. There is no limitation here.

[0151] Specifically, if the projection area needs to be updated regularly, the position acquisition module establishes an absolute spatial coordinate system with each instrument as the coordinate origin, and obtains the spatial position information of at least one user relative to the instrument;

[0152] The position acquisition module generates the actual coordinate interval (X1, X2...X3) of the user in the absolute space coordinate system according to the spatial position information. n , Y1, Y2...Y n), and determine the actual coordinate intervals (X1, X2...X n , Y1, Y2...Y n ) of the reference coordinate center (X c , Y c );

[0153] The position acquisition module is based on the reference coordinate center (X c , Y c ) Establish a two-dimensional space model;

[0154] The position acquisition module calculates the central area of ​​the two-dimensional space model relative to the projection surface, marks it as the area to be projected, and then performs a flatness test on the area to be projected to determine whether the area to be projected is the target projection area. If not, the addressing module automatically searches for the area to be projected for flatness test to determine the projection area.

[0155] After determining the projection area, if the user's position changes and the projection area needs to be adjusted, the information projection device adjusts the projection area based on the reference coordinate center (X c , Y c ) Generate theoretical coordinate interval ((X1, X2...X t , Y1, Y2...Y t ), the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t ) is larger than the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n )

[0156] Obtain the user's real-time position to generate real-time coordinate information relative to the instrument (X rt , Y rt ), determine the real-time coordinate information (X rt , Y rt ) is located in the theoretical coordinate interval (X1, X2...X t , Y1, Y2...Y t )Inside;

[0157] If not, generate the real-time coordinate information (X rt , Y rt ) as the first boundary, with the actual coordinate interval (X1, X2...X n , Y1, Y2...Y n ) relative to the real-time coordinate information (X rt , Y rt )Adjustment coordinate information of the maximum linear distance (X ad , Y ad) is the second boundary, generating a dynamic interval (X di1 , X di2 ...X din , Y di1 , Y di2 ...Y din ), according to the dynamic interval (X di1 , X di2 ...X din , Y di1 , Y di2 ...Y din ) generates real-time center coordinates, generates a dynamic two-dimensional space model according to the real-time center coordinates, and redefines the target projection area.

[0158] In one embodiment of the present invention, Fig.16 As shown, the information projection device also includes an identification module, and the identification module is configured to obtain operating condition information suitable for the instrument.

[0159] In this embodiment, the identification module is used for the information projection device to obtain the operating condition information corresponding to the instrument. For example, in a first time period, the first user, the second user and the third user simultaneously view the instrument, and the three users are responsible for different work contents. At this time, the identification module can obtain the operating condition information of the instrument corresponding to each user based on the information after identifying the user, and the projection module projects the projection image into the projection area in the projection surface, wherein the information processing module can adjust the sorting order of the projection image so that each operating condition information in the projection image can be close to the corresponding user, thereby improving the convenience of information viewing.

[0160] Furthermore, in some instruments with confidentiality requirements, such as Fig.17 As shown, the identification module includes a first identification unit and a second identification unit, wherein the first identification unit is configured to obtain the permission information of the user matching the instrument, wherein the first identification unit implements a biometric recognition function, such as recognizing the user's fingerprint, pupil, face, voice, etc., so as to obtain the user's permission information relative to the instrument: the second identification unit obtains the operating condition information matching the instrument according to the permission information obtained by the first identification unit, so that different users can only obtain the operating condition information of their corresponding instruments, thereby ensuring that the detection results of the instrument are not leaked.

[0161] In one embodiment of the present invention, the system supporting long-distance prompting of instrument status also includes a prompt light, which is arranged on the instrument and is set away from the information projection device. For example, when the user is relatively close to the instrument, the operating condition information of the instrument can be judged by judging the display status of the prompt light, such as color, flashing frequency, etc., thereby improving the convenience of viewing information of the instrument.

[0162] Based on all the above technical solutions, the system supporting remote prompt of instrument status also includes a sound-emitting device, which is configured to generate audio including operating condition information based on operating condition information. Specifically, the instrument generates an excitation current based on the operating condition information, and then the excitation current flows through the voice coil in the sound-emitting device, so that the voice coil cuts the magnetic field of the magnetic circuit system and moves back and forth, and the voice coil drives the diaphragm and the air to vibrate, thereby generating audio including operating condition information. The audio is combined with the projected image to further improve the traceability of the operating condition information. In another embodiment, the sound-emitting device is configured to generate fault alarm audio. When the information processing module includes warning information that the instrument needs to be paused, the sound-emitting device issues a fault alarm based on the warning information, so that the user can detect problems with the instrument at the first time, thereby improving the safety of the instrument. It can be understood that the two sound-emitting devices of the sound-emitting device can be combined to produce the third embodiment. Specifically, the sound-emitting device includes a first sound-emitting unit and a second sound-emitting unit. The first sound-emitting unit is configured to generate audio containing operating condition information based on operating condition information, and the second sound-emitting unit is configured to generate fault alarm audio. When receiving different excitation currents, one sound-emitting unit operates and the other sound-emitting unit suspends operation to avoid sound interference and reduce sound clarity.

All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
