[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 and Figure 2 As shown, the utility model provides an implementation of a liquid level detection device, including a tube body 1, an image acquisition module 2 and a data terminal; both ends of the tube body 1 are connected to the component of the liquid level to be measured; the liquid level in the tube body 1 corresponds to the liquid level in the component of the liquid level to be measured; the tube body 1 is made of transparent material and is vertically arranged; the image acquisition module 2 is located outside the concentration device 10; the lens of the image acquisition module 2 is arranged toward the tube body 1, and the field of view of the image acquisition module 2 can cover the tube body 1; the image acquisition module 2 is connected to the data terminal through the communication module to upload image data in real time.

[0026] The image acquisition module 2 takes a picture of the liquid in the transparent tube 1, uploads the image data to the data terminal, and identifies the pixel points to obtain the height of the liquid level in the tube 1, and then the height of the liquid level in the component to be measured.

[0027] In this embodiment, the tube body 1 is a glass tube, and the image acquisition module 2 is an industrial camera.

[0028] The present application also provides an embodiment, such as Figure 1 As shown:

[0029] A box body 3 is provided on the outside of the component of the liquid level to be measured, and the box body 3 wraps the tube body 1 and the image acquisition module 2 inside to protect the tube body 1 and the image acquisition module 2; a light source 4 is provided in the box body 3, and the light source 4 can provide light for the field of view covered by the image acquisition module 2, so that the image acquisition module 2 can collect image data of the liquid level in the tube body 1.

[0030] In this embodiment, the light source 4 is an LED lamp.

[0031] In this embodiment, the tube body 1 can display a highest position in the field of view of the image acquisition module 2 that is at least not lower than the highest liquid level in the component to be measured, and the tube body 1 can display a lowest position in the field of view of the image acquisition module 2 that is at least not higher than the lowest liquid level in the component to be measured.

[0032] To this end, an embodiment is provided, such as Figure 1 As shown:

[0033] The two ends of the tube body 1 are connected to the component of the liquid level to be measured through the pipe connectors 5 respectively. The connection positions of the two pipe connectors 5 and the component of the liquid level to be measured are respectively located above the maximum liquid level and below the minimum liquid level in the component of the liquid level to be measured, so as to ensure that the liquid level inside the component of the liquid level to be measured can be displayed in the glass tube; at the same time, it is ensured that the corresponding maximum liquid level and minimum liquid level in the tube body 1 are located in the field of view of the image acquisition module 2, so that the liquid level in the tube body 1 can be acquired by the image acquisition module 2.

[0034] In this embodiment, it is necessary to set a scale on the tube body 1 so that the auxiliary image acquisition device 2 can obtain the specific height of the liquid level in the tube body 1 more intuitively.

[0035] To this end, an embodiment is provided in which a scale is provided on the inner wall of the tube body 1 along the length direction of the tube body 1 and is located in the field of view of the image acquisition module 2, and the measurement range of the scale includes the highest liquid level in the component to be measured and the lowest liquid level in the component to be measured. The image acquisition device 2 can clearly obtain the specific height of the liquid surface in the tube body 1 by using the scale as a reference.

[0036] However, in the above embodiment, the image acquisition module 2 may recognize the scale line as the liquid surface, resulting in recognition error.

[0037] In order to avoid the above situation, an embodiment is provided. Figure 1 As shown:

[0038] A scale 9 with a measuring range not less than the length of the tube body 1 is provided inside the box body 3, and the length direction of the scale 9 is consistent with the length direction of the tube body 1, and is located on one side of the tube body 1, so that the camera image acquisition module 2 can clearly determine the specific height of the liquid level to avoid recognition errors.

[0039] In order to reduce the influence of the liquid in the component to be measured on the liquid level in the tube, the present application provides an embodiment, such as Figure 1 As shown:

[0040] A valve 6 is provided on the connecting pipeline between the pipe connector 5 and the component whose liquid level is to be measured, and preferably the valve 6 is provided at the pipe connector 5; an interface 7 is also provided on the pipe connector 5, and preferably the interface 7 is provided on the pipe connector 5 located above, and the interface 7 is used to connect to the steam generator; a one-way valve 8 is provided at the interface 7.

[0041] When the detection device is used, the valve 6 is opened and the one-way valve 8 is closed; after the liquid level detection device is used, the one-way valve 8 is opened and steam is introduced to perform steam cleaning on the inside of the tube body 1 to prevent the liquid from staining the inner wall of the tube body 1 and affecting the next liquid level detection.

[0042] like Figure 1 and Figure 2 As shown, the present application also provides a specific implementation of a Chinese medicine concentration device, and a detection device is installed on the outer wall of the Chinese medicine concentration device 10.

[0043] This application provides specific embodiments of the detection device, such as Figure 1 As shown:

[0044] It includes a tube body 1 and an image acquisition module 2; the tube body 1 is located outside the concentration device 10; the tube body 1 is vertically arranged, and its two ends are respectively connected to the concentration device 10; the tube body 1 is made of transparent material; the image acquisition module 2 is located outside the concentration device 10; the lens of the image acquisition module 2 is arranged toward the tube body 1; the image acquisition module 2 is connected to the data terminal through the communication module to upload image data in real time.

[0045] In this embodiment, the tube body 1 is a glass tube. In this embodiment, the image acquisition module is an industrial camera.

[0046] The decocted decoction is injected into the concentrator 10 from the medicine injection port. The tube body 1 and the concentrator 10 are connected structures. There is a corresponding relationship between the liquid level in the concentrator 10 and the liquid level in the tube body 1. The height of the liquid level pixel point in the tube body 1 is queried by taking a photo with an industrial camera to obtain the height of the liquid level in the concentrator 10.

[0047] After comparing the image data collected by the image acquisition module 2 for multiple times, the data terminal obtains the accurate height of the liquid level in the concentration device.

[0048] The pixel points are used to know the liquid level in the concentration device 10 and whether the set concentration capacity has been reached, and a liquid level prediction curve and a predicted concentration time can be generated. The entire concentration process does not require shutdown, the data is accurate, and the data can be uploaded to the server to observe the concentration process in real time. It also has the function of tracing the production process.

[0049] Furthermore, an embodiment is provided, in which a box body 3 wraps the tube body 1 and the image acquisition module 2 inside the box body 3; a light source 4 is provided inside the box body 3, and the box body 3 protects the tube body 1 and the image acquisition module 2. The internal light source 4 provides light, so that the image acquisition module 2 can collect image data of the liquid level in the tube body 1.

[0050] In this embodiment, the light source 4 is an LED lamp.

[0051] In order to facilitate the image acquisition module to more intuitively obtain the liquid level height in the tube body 1, an embodiment is provided:

[0052] A scale ruler 9 is provided inside the box body 3, and the scale ruler 9 is set at the same height as the tube body 1, so that the scale value of the scale ruler corresponds to the actual height of the liquid level in the tube body, and the scale ruler and the tube body can be simultaneously captured by the lens of the image acquisition module 2, so that the image acquisition module 2 can clearly determine the specific height of the liquid level, avoiding the camera identifying the scale line as the liquid surface when the scale line and the liquid level are close, causing recognition errors.

[0053] With respect to the connection structure between the tube body and the concentrating device, an embodiment is provided, such as Figure 1 and Figure 2 As shown:

[0054] The tube body 1 is connected to the concentrating device 10 via the pipe connector 5. The connection positions of the two pipe connectors 5 and the concentrating device 10 are respectively located above the maximum liquid level and below the minimum liquid level in the concentrating device; no matter what the liquid level of the traditional Chinese medicine liquid in the concentrating device is, its liquid level can be displayed in the glass tube.

[0055] In this embodiment, a valve 6 is provided on the pipe connector 5; an interface 7 is provided on the pipe connector 5, preferably an interface 7 is provided on the upper pipe connector 5, and the interface 7 is used to connect to the steam generator; a one-way valve 8 is provided at the interface 7.

[0056] During the process, the valve 6 located at the bottom can be adjusted to reduce the influence of the boiling of the liquid in the concentrator 10 on the liquid level inside the tube body 1, so that the liquid level measurement is more accurate.

[0057] After the concentration device 10 completes the concentration and cleaning, the one-way valve 8 at the interface 7 is opened to allow steam to enter the tube body 1. The steam blows from top to bottom to clean the tube body 1, thereby preventing factors such as residual liquid and cleaning water sticking to the wall from affecting the next liquid level detection.

[0058] When detecting the liquid level, the two valves 6 are in the open state and the one-way valve 8 is in the closed state. The influence of the boiling liquid surface in the pot on the liquid surface in the glass tube is reduced by adjusting the valve 6. After debugging is completed, the size and opening of the valve 6 are no longer adjusted; when steam cleaning is performed, the one-way valve 8 is in the open state, and steam enters the tube body 1 to clean the inner wall of the tube body 1.

[0059] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
