Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of experimental monitoring equipment, and particularly relates to a stability automatic identification device. BACKGROUND

[0002] In laboratory research in the fields of chemistry, biology, material science and the like, a large number of experimental reactions need to be placed under specific conditions for a period of time, and the color change process of the reaction system needs to be continuously observed. Such experiments usually require the experimental personnel to record the color change at fixed time intervals to obtain reaction kinetics data or determine the experimental endpoint.

[0003] During the experiment, the experimental object is usually placed in a closed space to reduce the interference of environmental variables on the experimental results during the control of the experiment, and the experimental personnel can only observe and record the color change of the experimental object through the reserved observation window.

[0004] However, long-time observation by the human eye will have the following problems and affect the accuracy of the experiment.

[0005] 1. Long-time continuous observation of the experimental sample will cause visual fatigue of the experimental personnel, and especially when multiple samples need to be monitored simultaneously in high-throughput experiments, the color sensitivity of the human eye will rapidly decrease. Studies have shown that after more than 30 minutes of continuous observation of the color step change, the recognition accuracy of the human eye for similar color differences decreases by more than 40%.

[0006] 2. There are individual differences in color perception, and different observers may have deviations in describing the same color. Especially when observing the gradual change process, the hue, saturation, lightness and the like recorded by artificial observation lack objective quantitative standards, which reduces the comparability of experimental data.

[0007] 3. Artificial observation usually adopts a minute-level time interval (such as recording once every 5 minutes), which may miss the key color transition nodes that occur rapidly. For slow change processes, data points are also easily sparse due to too long observation intervals.

[0008] At the same time, certain experiments are in a critical state near the end of the experiment, and the value-keeping personnel will have certain dangers.

[0009] Therefore, it is urgent to develop an observation device capable of automatically, continuously and objectively recording the color change of the experimental system to solve the disadvantages of manual observation and recording of the color system change in the laboratory. CONTENT OF THE INVENTION

[0010] In order to solve the problem that the color change of the measured object needs to be observed and recorded by the human eye in the experiment, and some experiments are in an unstable state near the end of the experiment, which may threaten the personal safety of the experimenters, the application provides a stability automatic identification device.

If the comparison result is abnormal, that is, the color does not match the color that should appear at this stage of the experiment, the result is saved and an alarm is sent. The continuous automatic recording of the entire color-changing experiment and the timely prompt when an abnormality occurs are realized. When an abnormality occurs during the experiment or the experimental object is in a critical state near the end of the experiment, the experimenter is not on site, so the experimenter will not be injured. The data points of the image information recorded by the image acquisition device are relatively uniform and dense, and the recorded results are relatively accurate.

[0019] Optionally, the light blocking ring is slidably mounted on the mounting cylinder. The mounting cylinder is provided with a fixing member. The fixing member is used for fixing the light blocking ring.

[0020] Optionally, the inner wall of the mounting cylinder is designed as white color, the light of the light supplement lamp is irradiated towards the inner wall of the mounting cylinder, and the roughness of the inner wall of the mounting cylinder is designed to realize the diffuse reflection of the light of the light supplement lamp, so that the light of the light supplement lamp is supplemented to the observation window of the experimental equipment.

[0021] Optionally, the image acquisition module and the light supplement lamp are slidably arranged in the mounting cylinder along the axial direction of the mounting cylinder, the mounting cylinder is provided with a first fixing mechanism for fixing the light supplement lamp, and the mounting cylinder is provided with a second fixing mechanism for fixing the image acquisition module.

[0035] The following is in conjunction with the appendix Figure 1 —6 provides further details regarding this application.

[0036] In laboratory research in fields such as chemistry, biology, and materials science, many experimental reactions need to be left to stand under specific conditions for a period of time, and the color change process of the reaction system needs to be continuously observed. Traditional experimental processes rely on the human eye of the experimenter to observe and record the results. However, the results are easily affected by objective factors such as eye fatigue and different people's perception of color, which can lead to deviations in the recorded results.

[0037] At the same time in some experimental process, for example, the stability of the experiment, when the experiment is about to end, the experimental object will be in unstable critical state, may appear explosion and cause on-site personnel injury.

[0038] In view of the defects existing in the above traditional experiment, the stability automatic identification device is disclosed, referring to Figure 1 , including image acquisition device 1, central control computer 2 and alarm device 3.

[0039] Referring to Figure 1 , in the process of standing, the image information of the experimental object is collected by the image acquisition device 1, and then the image information is transmitted to the central control computer 2 for comparison and analysis with the data in the database. If the color of the experimental object in the image is the same as the color of the experimental object in the standard experiment process in the time period or similar in the error allowable range after comparison and analysis, the result is stored and the next group of image data is recorded. If the color of the experimental object in the image is different from the color of the experimental object in the standard experiment process in the time period after comparison and analysis, the result is stored, the next group of image data is recorded, and the alarm device 3 is started to warn the experimental personnel.

[0040] And because the experimental personnel are not on site, if the experimental object has a critical reaction, the experimental personnel are not easy to be injured. The alarm device 3 adopts an audible and visual alarm.

[0041] Referring to Figure 3 , the image acquisition device 1 includes a mounting cylinder 12, a support 11 and an image acquisition module 13.

[0042] Referring to Figure 3 , the support 11 adopts a lifting support 11, which is a conventional technical means, and the person skilled in the art can select according to the specific situation. The first support plate 111 is fixedly installed at the top of the support 11 and is horizontal. The second support plate 112 is horizontally slidably installed on the first support plate 111. The first support plate 111 is screw-mounted with a locking screw for fixing the second support plate 112.

[0043] Referring to Figure 3 and Figure 4 , the mounting cylinder 12 is fixedly installed on the second support plate 112, the axis of the mounting cylinder 12 is horizontal and perpendicular to the sliding direction of the second support plate 112, one end of the mounting cylinder 12 is closed, a light blocking ring 15 is slidably installed in the open end of the mounting cylinder 12, and the image acquisition module 13 is located in the closed end of the mounting cylinder 12. The image acquisition module 13 is used to shoot images through the open end of the mounting cylinder 12. The image acquisition module 13 can select the corresponding camera of the prior art according to the specific image shooting requirement. In this embodiment, a high-resolution camera is selected.

[0044] With reference to Figure 2 and Figure 5 In assembly, one end of the light blocking ring 15 can be inserted into the observation window of the experimental device 10, so that the installation cylinder 12 is in closed connection with the experimental device 10, and external light is blocked by the light blocking ring 15 and cannot enter between the installation cylinder 12 and the observation window of the experimental device 10, so that the image acquisition module 13 is not disturbed by external light when shooting images, and the color of the experimental object in the image shot by the image acquisition module 13 is the actual color of the experimental object.

[0045] With reference to Figure 3 and Figure 4 , and in assembly, the position of the installation cylinder 12 can be adjusted by sliding the second support plate 112, so that when the position of the installation cylinder 12 needs to be adjusted, the entire device does not need to be moved, and the adjustment is more convenient and labor-saving.

[0046] The installation cylinder 12 is provided with a fixing member, which fixes the light blocking ring 15 when the light blocking ring 15 is inserted into the observation window of the experimental device, so that the light blocking ring 15 is not easily shaken out of the observation window of the experimental device 10 due to external reasons such as vibration.

[0047] With reference to Figure 3 and Figure 4 , the opposite two side walls of the installation cylinder 12 are each provided with a waist-shaped hole 122, the length direction of the waist-shaped hole 122 is parallel to the axis of the installation cylinder 12, and the fixing member includes two positioning bolts respectively slidingly installed in the two waist-shaped holes 122, and the cap of the positioning bolt is a cylindrical rotating handle. One end of the positioning bolt is threadedly connected with the side wall of the light blocking ring 15 through the waist-shaped hole 122.

[0048] With reference to Figure 3 and Figure 4 , the light blocking ring 15 blocks the waist-shaped hole 122, and after the light blocking ring 15 is inserted into the observation window of the experimental device 10 to the appropriate position, the positioning bolt is tightened, and the cap of the positioning bolt abuts against the side wall of the installation cylinder 12 to fix the light blocking ring 15. The fixing is more convenient, and at the same time, external light is not easily entered into the installation cylinder 12 when the light blocking ring 15 is adjusted.

[0049] With reference to Figure 3 and Figure 4The installation cylinder 12 is provided with a light supplement lamp 14. The light supplement lamp 14 is used for supplementing light for the experimental object when the image acquisition module 13 captures an image, and the light supplement lamp 14 irradiates the inner wall of the installation cylinder 12. The roughness of the inner wall of the installation cylinder 12 is designed to cause diffuse reflection of light. The light of the light supplement lamp 14 is irradiated to the experimental object through the diffuse reflection of the inner wall of the installation cylinder 12, so that most of the light reflected by the observation window of the experimental device from the light supplement lamp 14 is not reflected to the lens of the image acquisition module 13, and the light reflected by the observation window of the experimental device from the light supplement lamp 14 does not interfere with the image capturing of the image acquisition module 13 or the interference is within an allowable range.

[0050] With reference to Figure 3 and Figure 4 , the light supplement lamp 14 adopts white light, and the inner wall of the installation cylinder 12 is also designed to be white, so that the light of the light supplement lamp 14 does not interfere with the color of the image captured by the image acquisition module 13. At the same time, since the light of the light supplement lamp 14 is reflected to the observation window of the experimental device through diffuse reflection, the selection range of the irradiation angle of the light supplement lamp 14 is relatively wide, and accurate calculation is not required when designing the irradiation angle of the light supplement lamp 14, thereby reducing the workload during design and subsequent adjustment of the angle of the light supplement lamp 14.

[0051] With reference to Figure 3 and Figure 4 , the light supplement lamp 14 and the image acquisition module 13 are slidably installed in the installation cylinder 12 along the axis direction of the installation cylinder 12.

The first fixing mechanism 6 includes a mounting frame 61 and a plurality of first fixing bolts.

[0054] With reference to Figure 3 and Figure 4, for the case of not needing to adjust the irradiation angle of the light supplement lamp 14, the mounting frame 61 comprises a long strip-shaped mounting plate 611, the mounting plate 611 blocks the first long hole 121, the first long hole 121 is slidably provided with a plurality of first fixing bolts, one end of the first fixing bolt is slidably penetrated through the first long hole 121 and is threadedly connected with the mounting plate 611, one end of the mounting plate 611 is in a bent shape, and the light supplement lamp 14 is fixedly installed at the bent end of the mounting plate 611. When the mounting plate 611 is adjusted to the appropriate position, the first fixing bolt is tightened, the first fixing bolt is tightly abutted against the outer side wall of the mounting cylinder 12 to complete the fixing of the mounting plate 611, and the adjustment of the light supplement lamp 14 is relatively simple.

[0055] With reference to Figure 6 , for the case of needing to adjust the irradiation angle of the light supplement lamp 14, the mounting frame 61 is different from the above mounting frame 61 only in that the bent end of the mounting frame 61 is replaced by an adjusting plate 613, the adjusting plate 613 is rotationally installed on the mounting frame 61, and the light supplement lamp 14 is fixedly installed on the adjusting plate 613. The irradiation angle of the light supplement lamp 14 is adjusted by rotating the adjusting plate 613.

[0056] The adjusting plate 613 is rotationally installed with a first connecting rod 614 on the side away from the light supplement lamp 14, the first connecting rod 614 is rotationally installed with a second connecting rod 615, the mounting plate 611 is integrally provided with a connecting pipe 612, one end of the connecting pipe 612 is slidably penetrated through the first long hole 121, the second connecting rod 615 is vertically and slidably penetrated through the connecting pipe 612, the side wall of the connecting pipe 612 is threadedly installed with a clamping screw, and after the clamping screw is tightened, the clamping screw tightly abuts against the second connecting rod 615 to form a fixing between the second connecting rod 615 and the connecting pipe 612.

[0057] The rotation connection part of the first connecting rod 614 and the second connecting rod 615 is rotationally protruded away from the mounting plate 611, so as to facilitate the adjustment of the first connecting rod 614 and the adjusting plate 613 by sliding the second connecting rod 615.

[0058] With reference to Figure 3 and Figure 4 , the second fixing mechanism 7 comprises a base plate 71 and a sliding plate 72, the base plate 71 is fixedly installed on the closed end of the mounting cylinder 12 as the bottom wall of the lower side of the closed end of the mounting cylinder 12, the base plate 71 is provided with a second long hole 711 along the axial direction of the mounting cylinder 12, the sliding plate 72 is attached to the top wall of the base plate 71, a plurality of second fixing bolts are slidably installed in the second long hole 711, one end of the second fixing bolt is threadedly connected with the sliding plate 72, and the sliding plate 72 is slidably installed on the base plate 71 through the second fixing bolt.

[0059] With reference to Figure 3 and Figure 4The image acquisition module 13 is fixedly installed on the sliding plate 72 by bolts. The sliding plate 72 closes the second long hole 711. When the image acquisition module 13 slides to the appropriate position, the second fixing bolt is tightened, and the second fixing bolt is tightly pressed against the base plate 71 to complete the fixing of the sliding plate 72 and the image acquisition module 13.

[0060] The baffle 8 is fixedly installed in the mounting cylinder 12 by bolts. The baffle 8 is provided with a shooting hole 81 and a light supplementing hole 82.

[0061] The baffle 8 further blocks the light reflected by the glass of the observation window of the experimental equipment 10, thereby further improving the image quality of the shooting.

[0062] Meanwhile, the temperature sensor 9 is also arranged on the mounting cylinder 12 to detect the temperature inside the experimental equipment 10, so as to exclude the interference of the temperature variable on the experimental results.

[0063] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
