The current laboratory control processes and methods generally require staff to regularly inspect the laboratory to check the remaining reagents in the containers, and then add insufficient reagents to make the reagent inventory in the containers meet the standards to meet the needs of the next experimental user.

[0004] However, the existing equipment management method of regularly inspecting the laboratory manually and then adding insufficient reagents based on the inspection results still requires a lot of manpower, is prone to human errors and confusion, such as reagent replenishment errors, and has relatively low work efficiency. On the other hand, it does not meet the current development requirements of building an intelligent, efficient and accurate laboratory management system. Summary of the invention

[0036] In order to solve the technical problems of low efficiency and easy replenishment errors in the equipment management mode of the prior art, which is to manually inspect the laboratory on a regular basis and then manually add the insufficient reagents according to the inspection results; the present application provides an equipment information management method and system, which constructs an equipment information management system by setting a data processing module and an image acquisition module, an RFID base station module and an early warning module respectively connected to the data processing module, for automatically monitoring the reagent surplus, thereby improving the management efficiency and avoiding the equipment management mode of manually inspecting the laboratory on a regular basis and then manually adding the insufficient reagents according to the inspection results; specifically, the image acquisition module includes multiple image acquisition units, an RFID base station module and an early warning module respectively connected to the data processing module.

Then, the automatic management of the equipment is realized, and the management efficiency is improved.

[0037] In order to facilitate understanding of the present invention, several embodiments of the present invention are provided below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0038] Embodiment 1

[0039] See also Figure 1 , which is a device information management method in the first embodiment of the present invention, is applied to a device information management system, and is specifically applied to a data processing module in the device information management system. The method includes steps S101 to S103:

[0040] S101 . Acquire a reagent liquid level image of a container, and acquire the reagent liquid level height of the current container according to the reagent liquid level image, so as to calculate the reagent remaining amount of the current container according to the reagent liquid level height.

[0041] The container bottom shapes identified by the system include regular shapes and irregular shapes. Regular shapes include round and square. Irregular shapes are shapes other than regular shapes. Specifically, irregular shapes include container bottom shapes with wavy edges. As a specific example, since the container bottom shape is obtained by identifying the reflected light of the RFID tag through the RFID identifier, and since the RFID tag is generally a circular piece with a certain unit diameter, and the larger the diameter of the RFID tag, the more irregular the container bottom shape is. Affected by this, the container bottom shape curve collected by the system through the image acquisition unit (e.g., camera) is a regular shape in an ideal state, that is, in an ideal state, the contour of the container bottom shape is a regular curve. For example, when the container is a measuring cup, the bottom shape identified by the system in an ideal state is a circle, which belongs to a regular shape; but in the actual process, affected by the randomness of the container placement position, the obtained container bottom shape curve is generally a container bottom shape with a wavy edge, or a container bottom shape with a serrated edge. Therefore, it is necessary to process the irregular container bottom shape to obtain a container bottom shape area with a higher accuracy, thereby improving the monitoring accuracy of the reagent residue.

[0042] Among them, the method for calculating the reagent remaining amount in the current container according to the reagent liquid level includes: obtaining the area in the container placement area where the RFID tag is not identified according to the RFID identifier to use the area as the required area for container storage; calculating the required area for container storage according to the required area for container storage. It should be further explained that the container in the technical solution of the present application is a container with a consistent cross-sectional shape. Since the cross-sectional area of ​​the wall thickness of the container is small, it can be ignored. Therefore, the required area for container storage is the cross-sectional area of ​​the container, and the reagent remaining amount in the current container is calculated based on the cross-sectional area of ​​the container and the reagent liquid level.

[0043] Specifically, since the RFID tag is located at the bottom of the container placement area, when a container is placed on the container placement area, the RFID tag at the bottom will be blocked. Therefore, the RFID identifier located above will identify other areas except the container blocking area, and the container blocking area can be constructed, and then the actual area outline of the container blocking area can be obtained. The required area for container storage can be calculated through the actual area outline.

[0044] In this embodiment, the method for calculating the required area for container storage according to the required area for container storage includes steps S1011 to S1014:

[0045] S1011. Obtain an area required for storing containers, and determine an actual area outline of the area required for storing containers.

[0046] S1012. Determine whether the area required for storing the container is a regular area based on the actual area contour.

[0047] In this embodiment, the actual area contour is identified, and whether the area required for container storage is a regular area can be determined according to the identification result. If the area required for container storage is a regular area, step S1013 is executed; if the area required for container storage is not a regular area, step S1014 is executed.

[0048] S1013. Calculate the area of ​​the area required for storing the container according to the calculation formula of the regular area.

[0049] For example, if the actual area outline is a circle, the area can be obtained according to the circle area calculation formula.

[0050] S1014, identifying the contour inflection points of the actual area contour, and sequentially connecting two adjacent contour inflection points to obtain multiple contour segments, the multiple contour segments are connected end to end to construct a closed virtual area contour, and the area required for container storage is calculated based on the virtual area contour.

[0051] Furthermore, before the step of calculating the required area for storing the container according to the virtual area outline, the step also includes steps S10141 to S10144:

[0052] S10141. Obtain the distance value between the contour segment and the actual area contour.

[0053] In order to avoid a large difference between the virtual area contour obtained by division and the actual area contour, in this embodiment, the virtual area contour obtained each time needs to be rechecked according to the spacing value between the contour segment and the actual area contour, so as to avoid a large difference between the virtual area contour and the actual area contour due to the spacing value being greater than the preset value, affecting the true area of ​​the actual area contour, and then affecting the calculation accuracy of the reagent residue, resulting in an early warning error.

[0054] S10142. Determine whether the spacing value is greater than a preset value.

[0055] As a specific example, the preset value of the spacing may be 0.2 cm. In practical applications, the preset value of the spacing may be selected according to actual conditions. Further, if the spacing value is greater than the preset value, step S10143 is executed, and the process returns to step S10141, until the spacing value is not greater than the preset value, and step S10144 is executed.

[0056] S10143. Obtain a contour segment corresponding to a spacing value greater than a preset value as a target contour segment, and obtain a corresponding target contour curve in the actual area contour according to the target contour segment, identify the curve inflection point of the target contour curve, and connect them with two adjacent contour inflection points respectively to obtain multiple contour segments. The multiple contour segments are connected end to end to construct a closed virtual area contour.

[0057] When there is a contour segment with a spacing value greater than a preset value, the contour segment is obtained and used as a target contour segment. According to the target contour segment, the corresponding target contour curve is obtained in the actual area contour, and then the target contour curve is divided twice to reduce the spacing value until it meets the preset value. Specifically, the curve inflection point of the target contour curve is identified, and connected with two adjacent contour inflection points to obtain multiple contour segments, and the multiple contour segments are connected end to end to construct a closed virtual area contour. Furthermore, in the method of identifying the curve inflection point of the target contour curve, and connecting with two adjacent contour inflection points to obtain multiple contour segments: if the target contour curve has multiple curve inflection points, the curve inflection points are connected in sequence to obtain a closed virtual area contour.

[0058] S10144. Calculate the area required for container storage based on the virtual area outline.

[0059] In this embodiment, the method for calculating the area required for container storage based on the virtual area outline includes: obtaining the geometric center of the virtual area outline, and connecting the outline inflection points respectively to divide the virtual area outline into a plurality of triangles; calculating the area of ​​each triangle respectively to obtain the areas of multiple triangles, and superimposing the area of ​​each triangle to obtain the area of ​​the virtual area outline, and the area of ​​the virtual area outline is the area required for container storage.

[0060] S102: Determine whether the reagent remaining amount meets the remaining amount threshold.

[0061] If the reagent remaining amount does not meet the remaining amount threshold, step S103 is executed; if the reagent remaining amount meets the remaining amount threshold, the process returns to step S101. As a specific example, the remaining amount threshold may be 5% of the total capacity of the container, that is, when the reagent remaining amount is less than 5% of the total capacity of the container, the system outputs an early warning message to issue an early warning of the remaining amount to warn of insufficient remaining amount. For example, for a container with a total capacity of 100 ml, the remaining amount threshold is 5 ml.

[0062] S103, outputting warning information to realize the warning of the remaining reagent amount.

[0063] When the system identifies that the reagent remaining amount is lower than the remaining amount threshold, the data processing module issues a remaining amount warning on the corresponding area of ​​the display terminal. In this embodiment, the display terminal is provided with multiple display interfaces, each display interface corresponds to a laboratory table, and the display interface is provided with an interface display area and an interface operation area, the interface display area corresponds to the container placement area one by one, and the interface operation area corresponds to the operation operation area one by one, so that when the interface display area flashes, it can be concluded that the reagent remaining amount in the container in the corresponding container placement area is insufficient and needs to be increased; thereby realizing automatic monitoring.

[0064] In summary, the device information management method in the above embodiment of the present invention constructs a device information management system by setting a data processing module and an image acquisition module, an RFID base station module and an early warning module respectively connected to the data processing module, which is used to automatically monitor the reagent residue, improve management efficiency, and avoid the equipment management method of manually adding insufficient reagents through regular manual inspection of the laboratory according to the inspection results; specifically, the image acquisition module includes a plurality of image acquisition units, the RFID base station module includes a plurality of position markers and identification units, each position marker and identification unit includes an RFID identifier and an RFID tag array, and the RFID tag array includes a plurality of RFID tags; the image acquisition unit is used to collect the reagent liquid level image inside the container to locate the remaining capacity of the reagent, and the RFID tag array is used to locate the container to leave / return the instrument placement area; further, the device information management method includes obtaining the reagent liquid level image of the container, obtaining the reagent liquid level height of the current container according to the reagent liquid level image, and calculating the reagent residue of the current container according to the reagent liquid level height; judging whether the reagent residue meets the residue threshold; if not, outputting early warning information to realize the reagent residue early warning. Then the automatic management of the equipment is realized, and the management efficiency is improved.
