Description

Technical Field

[0001] The present invention relates to the technical field of blood management, and in particular to a blood tracing and intelligent management method based on a digital blood bag. Background Art

[0002] In traditional blood management at blood stations, barcode blood donation labels are usually pasted on blood bags. During the blood bag handover process, a barcode gun is required to manually scan and identify the barcode on each blood bag.

[0003] However, the prior art has the following problems: the blood collection label is only pasted on the surface of the blood bag when blood is collected, and the label only contains blood-related information, and the factory information of the blood bag cannot be traced. Therefore, it is impossible to quickly confirm whether the blood bag meets the blood storage requirements when blood is collected; because the blood collection label is only pasted on the surface of the blood bag when blood is collected, a corresponding number of blood bags and a corresponding number of labels need to be prepared before blood collection. The preliminary preparation work is cumbersome and the workload is large. In addition, when the blood collection label is manually pasted, there is a risk of sticking the wrong label on the blood bag. After the label is torn off and pasted again, the viscosity of the label is reduced. When the label is not pasted in a standardized manner, there is a risk of the label falling off; in addition, for the equipment used in the blood preparation and storage links, such as centrifuges and refrigerators, it is necessary to manually set the equipment operating parameters when using them, and intelligent control cannot be achieved, and manual settings are prone to errors. Summary of the invention

[0004] The purpose of the present invention is to propose a blood traceability and intelligent management method based on a digital blood bag, which at least solves one of the problems raised in the background technology. To achieve the purpose of the present invention, the following scheme is adopted:

[0005] A blood traceability and intelligent management method based on digital blood bags, comprising the following steps:

[0006] During the factory production of blood bags, pre-prepared RFID tags are implanted into each blood bag;

[0007] In the blood collection process, the unique identification code of the TID area of ​​the RFID tag of the blood bag is associated and bound with the blood donation serial number corresponding to the blood donor. When the blood is collected from the blood donor, the blood information corresponding to the blood donor is recorded and uploaded to the traceability system database;

[0008] In the blood storage process, when the blood bag is placed in the refrigerator, the TID area of ​​the RFID tag of the blood bag is automatically read by the refrigerator's built-in RFID reading module to obtain blood information and transmit the blood information to the refrigerator control system;

[0009] The refrigerator control system determines whether the current blood belongs to the blood category of this refrigerator based on the blood information. If not, it will issue a warning prompt. If so, it will automatically set the refrigerator to a storage temperature suitable for the blood category based on the storage temperature requirements corresponding to the blood category.

[0010] A further improvement is that after the pre-prepared RFID tag is implanted into each blood bag, the following steps are also included:

[0011] Install RFID equipment in the blood bag production line and connect it to the data interface of the factory production management system;

[0012] The RFID device is used to write the production coding information into the EPC area of ​​the RFID tag of each blood bag and record the corresponding blood bag production information and upload it to the traceability system database.

[0013] A further improvement is that the method further comprises the following steps:

[0014] In the blood collection process, before blood collection, the RFID tag on the blood bag is scanned by a preset RFID tag identification device to obtain the blood bag production information corresponding to the production coding information in the RFID tag to determine whether the blood bag production information meets the expected usage standards.

[0015] A further improvement is that the method further comprises the following steps:

[0016] In the blood usage link, the RFID tag on the blood bag of the blood to be used is first scanned by a preset RFID tag identification device to obtain the blood bag production information corresponding to the production coding information in the RFID tag, and determine whether the production information of the blood bag meets the expected usage standards. If it meets the standards, the RFID tag on the blood bag of the blood to be used is identified by the preset RFID tag identification device, and the unique identification code in the TID area of ​​the RFID tag is read to determine the blood donation serial number corresponding to the unique identification code, and the blood usage information is recorded, and the blood usage information corresponding to the blood donation serial number is uploaded to the traceability system database.

[0017] A further improvement is that the method further comprises the following steps:

[0018] In the blood preparation process, when the blood bag containing blood is placed in the centrifuge, the TID area and EPC area of ​​the RFID tag of the blood bag are automatically read by the built-in RFID reading module of the centrifuge to obtain the blood information and blood bag production information and transmit the blood information and blood bag production information to the centrifuge control system. The centrifuge control system obtains the blood type and blood bag specifications based on the blood information and blood bag production information and automatically sets the centrifuge speed and centrifugation time.

[0019] A further improvement is that the blood bag production information includes one or more of blood bag specifications, preset use, production date, shelf life, manufacturer, and production batch information.

[0020] A further improvement is that the blood information includes one or more of blood type, blood donor information, blood collection operator, blood type, blood collection time, expiration time, blood collection institution, and blood collection location.

[0021] A further improvement is that the method further comprises the following steps:

[0022] In the blood outbound link, the transportation destination location is obtained, the blood bags to be processed are loaded into the blood transportation equipment, the RFID tags of the blood bags to be processed in the blood transportation equipment are identified by the preset RFID tag identification device, the unique identification code of the TID area of ​​the RFID tag is read, the blood donation serial number corresponding to the unique identification code is determined, and the outbound transportation information is recorded, and the outbound transportation information corresponding to the blood donation serial number is uploaded to the traceability system database.

[0023] A further improvement is that the refrigerator control system continuously monitors the temperature inside the refrigerator and issues an alarm when it detects that the temperature inside the refrigerator does not meet the storage temperature requirement for blood.

[0024] A further improvement is that a label sticking area is provided on the outer surface of the blood bag, and the RFID label is stuck in the label sticking area.

[0025] Beneficial effects of the present invention:

[0026] The present invention integrates RFID technology into the entire process of blood bag production, blood collection, storage, transportation and use to construct a comprehensive and efficient traceability management method. Starting from the source of blood bag production, each blood bag is given a unique identification and bound to the production information. The blood bag is more convenient to use and there is no need to print and paste labels when using it, which effectively avoids confusion and errors.

[0027] The present invention automatically reads the TID area of ​​the RFID tag of the blood bag through the built-in RFID reading module of the refrigerator to obtain blood information and transmit the blood information to the refrigerator control system. When the refrigerator control system detects the blood type that is not to be stored in the refrigerator, it will immediately issue an early warning, which can prevent mis-storage, timely discover and correct potential errors, and enhance the safety of blood storage. The refrigerator control system can automatically set the most suitable storage temperature according to the read blood type, which is the key to ensuring the quality and safety of blood. Different types of blood have their own specific storage conditions, and intelligent temperature control reduces the risk of blood deterioration caused by improper temperature.

[0028] The present invention writes production coding information into the EPC area of ​​the RFID tag of each blood bag through RFID equipment in the factory production link of blood bags, records the corresponding blood bag production information and uploads it to the traceability system database, and then automatically reads the TID area and EPC area of ​​the RFID tag of the blood bag through the built-in RFID reading module of the centrifuge to obtain blood information and blood bag production information. The centrifuge control system automatically sets the rotation speed and centrifugation time according to different blood types and their corresponding blood bag specifications, which is very important for ensuring the quality and efficiency of blood component separation, and avoids poor processing effects caused by general settings not being suitable for specific blood types and blood bag specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 The present invention is a flow chart of a blood tracing and intelligent management method based on digital blood bags. DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment 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 should fall within the scope of protection of the present invention.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0032] Please refer to the attached Figure 1 The embodiment of the present invention proposes a blood traceability and intelligent management method based on a digital blood bag, comprising the following steps:

[0033] Step S1: In the factory production process of blood bags, a pre-prepared RFID tag is implanted into each blood bag.

[0034] It should be noted that in the process of manufacturing blood bags, a pre-prepared RFID tag is implanted into each blood bag by pasting. The RFID tag is a miniature electronic device containing a unique identifier and a readable and writable storage area, which can communicate with a special reader via radio waves.

[0035] By affixing RFID tags to blood bags before they leave the factory, the workload of affixing labels during blood collection can be reduced. When collecting blood, staff only need to take the labeled blood bags out of the packaging and no longer need to affix them on site, which improves the efficiency of the blood collection process and gives staff more time and energy to serve blood donors.

[0036] In addition, by pasting the RFID tags before leaving the factory, the RFID tags are pasted uniformly, which is more firm and more accurate. In the existing business process, RFID tags are pasted on site, and the pasting standards of each operator cannot be unified, and there are certain differences in the pasting effect; moreover, after the blood station purchases the labels, not all of them are used immediately. Some labels will degummed, deformed, etc. due to the storage environment, which is easy to cause the risk of falling off during the quick freezing of blood. The present invention can shorten the operation process and reduce the risk of falling off by pasting the RFID tags uniformly before the blood bags leave the factory.

[0037] Preferably, after the pre-prepared RFID tag is implanted into each blood bag, the following steps are also included: installing RFID equipment in the production line of blood bags and connecting to the data interface of the factory production management system; writing production coding information in the EPC area of ​​the RFID tag of each blood bag through the RFID equipment and recording the corresponding blood bag production information and uploading it to the traceability system database.

[0038] It should be noted that by remodeling the blood bag production line and providing a data interface for the blood bag production plant management system, relevant production information of the blood bag can be obtained. By writing production coding information in the EPC area of ​​the RFID tag of each blood bag, the blood bag can have the dual attributes of blood traceability and blood bag traceability.

[0039] When the blood bag with the RFID tag implanted passes through the production link equipped with the RFID reader, the RFID reader will automatically identify the RFID tag on each blood bag, write the production code information in the EPC (electronic product code) area of ​​the tag, and record the corresponding blood bag production information and upload it to the traceability system database. After writing the relevant information, the EPC area needs to be locked or permanently locked to prevent the EPC data from being illegally modified.

[0040] Step S2: In the blood collection process, the unique identification code of the TID area of ​​the RFID tag of the blood bag is associated and bound with the blood donation serial number corresponding to the blood donor. When blood is collected from the blood donor, the blood information corresponding to the blood donor's blood is recorded and uploaded to the traceability system database.

[0041] It is understandable that the blood donation serial number (unique blood donation code) is printed on the surface of the RFID tag when the RFID tag is produced as a unique blood identifier. TID (Tag Identification Number) is a globally unique, unchangeable identifier in the RFID tag to distinguish each independent tag.

[0042] The collected blood information of blood donors is uploaded to the traceability system database together with the previously established binding relationship between TID and blood donation serial number. The traceability system database will integrate this data with the previously recorded blood bag production information to form a complete blood traceability chain. In this way, from the production source of blood bags to the specific blood donor information and blood collection details, all are managed in an information-based manner, greatly enhancing the transparency and safety of blood products.

[0043] Step S3: In the blood storage process, when the blood bag is placed in the refrigerator, the TID area of ​​the RFID tag of the blood bag is automatically read by the built-in RFID reading module of the refrigerator to obtain blood information and transmit the blood information to the refrigerator control system.

[0044] Step S4: The refrigerator control system determines whether the current blood belongs to the blood category of the refrigerator based on the blood information. If not, a warning prompt is issued. If yes, the refrigerator is automatically set to a storage temperature suitable for the blood category based on the storage temperature requirements corresponding to the blood category.

[0045] In addition, the refrigerator control system continuously monitors the temperature inside the refrigerator and issues an alarm when it detects that the temperature inside the refrigerator does not meet the storage temperature requirements for blood.

[0046] It can be understood that the present invention automatically reads the TID area of ​​the RFID tag of the blood bag through the built-in RFID reading module of the refrigerator to obtain blood information and transmit the blood information to the refrigerator control system. When the refrigerator control system detects that the blood type is not what the refrigerator should store, it will immediately issue an early warning, which can prevent mis-storage, timely discover and correct potential errors, and enhance the safety of blood storage. The refrigerator control system can automatically set the most suitable storage temperature according to the read blood type, which is the key to ensuring blood quality and safety. Different types of blood have their own specific storage conditions, and intelligent temperature control reduces the risk of blood deterioration caused by improper temperature.

[0047] The RFID tag used in the present invention is preferably an ultra-high frequency electronic tag, which has the following advantages: 1. Each RFID tag has a unique UID / TID code; 2. It has strong anti-fouling ability and environmental adaptability, is suitable for harsh indoor and outdoor environments, and has extremely strong corrosion resistance to substances such as water, oil and chemicals; 3. It is small in size and has a variety of shapes. When in use, the area, shape and size can be flexible and changeable; 4. It can be reused and recycled, and has the function of repeatedly adding, deleting, modifying and updating the data stored in the label, which is more convenient and environmentally friendly; 5. It has high security, and the information is stored in the chip, and its data content can be encrypted and is not easy to be forged, tampered with or stolen; 6. It has strong penetration, and can still perform penetrating communication when covered by non-metallic or non-transparent materials such as paper, wood, and plastic; 7. It has a fast group reading function, and can read hundreds of tags at the same time, so that inventory can be quickly realized, so that a batch of blood bags can be quickly counted to see if they are expired.

[0048] As a preferred embodiment of the present invention, the following steps are also included:

[0049] In the blood collection process, before blood collection, the RFID tag on the blood bag is scanned by a preset RFID tag identification device to obtain the blood bag production information corresponding to the production coding information in the RFID tag to determine whether the blood bag production information meets the expected usage standards.

[0050] The blood bag production information includes, but is not limited to, one or more of blood bag specifications, preset use, production date, shelf life, manufacturer, and production batch information.

[0051] It is understandable that before the actual blood collection begins, medical staff will use a preset RFID tag identification device (such as a handheld RFID reader) to scan the RFID tag on the blood bag in the set, read the production coding information in the blood bag RFID tag through the RFID tag identification device, and retrieve the corresponding production information from the traceability system database, including but not limited to blood bag specifications, production date, expiration date, batch number, manufacturer and other information. This information is crucial for determining whether the blood bag is suitable for current use. Specifically, by comparing this production information with the expected use standards of the current blood collection operation, including but not limited to whether the blood bag specifications meet the requirements, whether it is within the validity period, whether it comes from a qualified manufacturer, whether there are any known quality problem recall records, etc., it is ensured that the blood bags used meet all safety and quality standards.

[0052] As a preferred embodiment of the present invention, the following steps are also included:

[0053] In the blood usage link, the RFID tag on the blood bag of the blood to be used is first scanned by a preset RFID tag identification device to obtain the blood bag production information corresponding to the production coding information in the RFID tag, and determine whether the production information of the blood bag meets the expected usage standards. If it meets the standards, the RFID tag on the blood bag of the blood to be used is identified by the preset RFID tag identification device, and the unique identification code in the TID area of ​​the RFID tag is read to determine the blood donation serial number corresponding to the unique identification code, and the blood usage information is recorded, and the blood usage information corresponding to the blood donation serial number is uploaded to the traceability system database.

[0054] It is understandable that before the blood is used for the patient, the RFID tag on the blood bag is scanned by a preset RFID tag identification device to obtain the production coding information and the corresponding blood bag production information. By checking this information, it is confirmed whether the blood bag is within the validity period. If the blood bag is not within the validity period, it may cause contamination to the blood. Once the blood bag passes the above-mentioned pre-use verification, the unique identification code of the TID area of ​​the blood bag RFID tag is read next. The identification code is directly associated with the blood donation serial number of the blood donor, so that the basic information of the blood donor, blood information and the complete history of the blood can be traced back to further verify. When using, record the specific information of blood use, such as the time of use, the place of use (department, hospital), the information of the patient receiving the blood, the information of the doctor or nurse performing the blood transfusion operation, etc., and upload the blood use information corresponding to the blood donation serial number to the traceability system database to complete the closed-loop traceability of the entire blood use process. In this way, every step of the operation from the production of the blood bag to the final use for the patient can be traced in the traceability system, ensuring the transparency and responsibility traceability of blood management.

[0055] As a preferred embodiment of the present invention, the following steps are also included:

[0056] In the blood preparation process, when the blood bag containing blood is placed in the centrifuge, the TID area and EPC area of ​​the RFID tag of the blood bag are automatically read by the built-in RFID reading module of the centrifuge to obtain the blood information and blood bag production information and transmit the blood information and blood bag production information to the centrifuge control system. The centrifuge control system obtains the blood type and blood bag specifications based on the blood information and blood bag production information and automatically sets the centrifuge speed and centrifugation time.

[0057] It can be understood that the present invention writes production coding information into the EPC area of ​​the RFID tag of each blood bag through RFID equipment in the factory production link of blood bags, records the corresponding blood bag production information and uploads it to the traceability system database, and then automatically reads the TID area and EPC area of ​​the RFID tag of the blood bag through the built-in RFID reading module of the centrifuge to obtain blood information and blood bag production information. The centrifuge control system automatically sets the rotation speed and centrifugation time according to different blood categories (such as whole blood, red blood cells, platelets, etc.) and their corresponding blood bag specifications. This is crucial to ensure the quality and efficiency of blood component separation, and avoids poor processing effects caused by general settings not being suitable for specific blood categories and blood bag specifications.

[0058] Specifically, the blood information includes but is not limited to one or more of blood type, blood donor information (name, gender, age, ID card information), blood collection operator, blood type, blood collection time, expiration time, blood collection agency, and blood collection location.

[0059] As a preferred embodiment of the present invention, the following steps are also included:

[0060] In the blood outbound link, the transportation destination location is obtained, the blood bags to be processed are loaded into the blood transportation equipment, the RFID tags of the blood bags to be processed in the blood transportation equipment are identified by the preset RFID tag identification device, the unique identification code of the TID area of ​​the RFID tag is read, the blood donation serial number corresponding to the unique identification code is determined, and the outbound transportation information is recorded, and the outbound transportation information corresponding to the blood donation serial number is uploaded to the traceability system database.

[0061] It is understandable that in the preparation stage for blood shipment, the scheduled transportation destination of the blood must be clarified first, which can be a hospital, blood bank or other medical institution. The destination information is crucial for planning the transportation route and ensuring that the blood is delivered on time. The blood bags that need to be shipped are loaded into professional blood transportation equipment according to the needs, such as a refrigerator with a temperature control function. During the loading process, the RFID tag on the blood bag is scanned using a preset RFID tag identification device, and the corresponding blood donation serial number is traced back through the unique identification code in the TID area, and then associated with the complete historical record of the blood bag, including blood information, blood bag production information, etc. At the same time, the current shipment time, transportation destination, transportation equipment number, estimated arrival time and other shipment information are recorded, and the shipment information associated with the blood donation serial number is uploaded to the traceability system database to update the circulation status of the blood product. In this way, even if the blood leaves the original storage place, its dynamics can be understood in real time through the traceability system database, ensuring full traceability and facilitating management and monitoring.

[0062] Preferably, a label pasting area is provided on the outer surface of the blood bag, and the RFID label is pasted in the label pasting area.

[0063] As a preferred solution of the present invention, in step S1: in the factory production link of blood bags, a pre-prepared RFID tag is implanted into each blood bag. After the pre-prepared RFID tag is implanted into each blood bag, the method further includes: using a high-resolution camera in conjunction with image recognition technology to take pictures and analyze the position of the tag to ensure that the RFID tag is accurately installed according to the predetermined position.

[0064] Using high-resolution cameras and image recognition technology to take pictures and analyze the location of tags, the specific methods to ensure that RFID tags are accurately installed in the predetermined locations include:

[0065] According to the size of the blood bag and the accuracy requirements for the label position, select a camera with sufficient resolution to ensure that the position of the RFID label can be clearly photographed. You can choose an industrial-grade camera with high pixels (such as more than 5 million pixels) and high frame rate (≥60fps) to ensure that the RFID label image on the blood bag can be quickly and clearly photographed. Install the camera on the production line to ensure that its position is stable and can cover the area where each blood bag passes. Determine the time and frequency of taking pictures to ensure that the image of the RFID label can be captured in time when the blood bag passes.

[0066] The collected images are preprocessed, including grayscale conversion, converting color images into grayscale images to reduce processing complexity; noise removal, applying algorithms such as median filtering or Gaussian filtering to remove noise and impurities in the image; edge enhancement, using methods such as Canny edge detection or Sobel operator to highlight the outline of the RFID tag.

[0067] A standard template image of the RFID tag is established in advance, and a template matching algorithm (such as the normalized cross-correlation method) is used to find the area in the captured image that has the highest matching degree with the standard template image to determine the position of the RFID tag. Alternatively, a shape recognition algorithm (such as the Hough transform) is used to directly identify a specific shape and accurately locate the position of the RFID tag.

[0068] The deviation between the identified RFID tag position and the predetermined position is calculated. If it exceeds the set threshold, it is determined to be position deviation. When the RFID tag position deviation is detected, a signal is immediately sent to the production line control system to adjust the position of the manipulator or conveyor belt to ensure that the RFID tag of the next product is accurately attached and implanted. Those skilled in the art can set the threshold value according to the actual accuracy requirements.

[0069] In addition, if the set threshold is not exceeded, it is determined that there is no deviation in the position. At this time, the image recognition algorithm is further used to analyze whether the edge of the RFID tag is flat, whether there is any warping or wrinkling, so as to determine whether the RFID tag and the blood bag are tightly attached. The specific method includes: based on deep learning technology, such as convolutional neural network, a large number of qualified and unqualified image samples of known RFID tags attached to blood bags are collected (unqualified means that the position of the RFID tag is not deviated, but it is not tightly attached to the blood bag, that is, it is not flat, there is warping or wrinkling; qualified means that the position of the RFID tag is not deviated and it is tightly attached to the blood bag, flat, without warping or wrinkling), and the image is analyzed. For example, edge detection (such as Canny edge detection), shape recognition, and texture analysis are used to automatically identify and extract key features of RFID tags, including the contour, straightness, smoothness, etc. of the RFID tags, which are used to train image recognition models to learn to distinguish between flat RFID tags without warping or wrinkles and RFID tags with problems; the RFID tag images taken by the camera on the production line are input into the trained image recognition model, and the image recognition model analyzes the collected RFID tag images in real time. Once the RFID tag is found to be poorly attached to the blood bag, an alarm is immediately issued and the blood bag is automatically marked so that appropriate treatment measures can be taken.

[0070] Regularly collect statistics and analyze the photographed and analyzed data to understand the accuracy and stability of the RFID tag location, find possible problems and directions for improvement, and optimize the production process and improve the layout of the production line based on the results of data analysis to improve the accuracy and consistency of RFID tag implantation.

[0071] As a preferred solution of the present invention, the refrigerator control system continuously monitors the temperature inside the refrigerator, including detecting the temperature uniformity of different positions inside the refrigerator at regular intervals. The specific method includes: Hardware deployment: several high-precision temperature probes are evenly installed in different areas inside the refrigerator, including the top, bottom, side, front and back areas. Data acquisition and real-time monitoring: The high-precision temperature probe is set to automatically collect and upload temperature data to the refrigerator control system at regular intervals (such as 1 hour), and the real-time temperature distribution diagram of different areas inside the refrigerator is displayed through the real-time monitoring interface, which intuitively displays the temperature and change trend of each point. Temperature mapping and analysis: A 3D temperature distribution diagram is drawn through the drawing software built into the refrigerator control system, and different temperature intervals are distinguished by color to facilitate the identification of hot spots and cold spots. Thresholds are set, and abnormal areas that exceed the threshold range are automatically marked, and the causes of unevenness are analyzed. Check whether there are obstructions near the temperature probe in the abnormal area and whether the airflow is blocked. Adjustment of airflow inside the refrigerator: According to the monitoring results, if the airflow is blocked, the fan speed inside the refrigerator is dynamically adjusted to increase or decrease the airflow near the abnormal area to promote temperature uniformity.

[0072] The present invention integrates RFID technology into the entire process of blood bag production, blood collection, storage, transportation and use to construct a comprehensive and efficient traceability management method. Starting from the source of blood bag production, each blood bag is given a unique identification and bound to the production information. The blood bag is more convenient to use and there is no need to print and paste labels when using it, which effectively avoids confusion and errors.

[0073] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
