[0036] Please also refer to Figure 1 and Figure 2 ,in Figure 1 Schematic diagram of a scenario of a dynamic reading method of an RFID system based on intelligent decision-making according to an embodiment of the present invention. Figure 2 FIG. 1 is a flow chart of a dynamic reading method of an RFID system based on intelligent decision-making provided by an embodiment of the present invention. Figure 1 As shown, the RFID system dynamic reading method based on intelligent decision-making provided by the embodiment of the present invention is applied to an RFID reading system, wherein the RFID reading system includes a server 10, an image acquisition device 20 and an RFID reader-writer group 30, wherein the image acquisition device 20 and the plurality of RFID readers included in the RFID reader-writer group 30 are all communicatively connected to the server 10. The server 10 may be an edge server that is no more than a first preset distance (such as 100 m) away from the deployment location of the image acquisition device 20 and the RFID reader-writer group 30, or may be a cloud server that is more than the first preset distance away.

[0037] like Figure 2 As shown, the method includes the following steps S110-S160.

[0038] S110. The image acquisition device responds to a venue scene recognition instruction, obtains a current venue image corresponding to the venue scene recognition instruction, and sends the image to the server.

[0039] In this embodiment, after the RFID reading system is deployed in a certain venue (such as a production workshop where an industrial production line is located), in order to quickly determine the reader reading strategy that needs to be deployed by the RFID reader group, the image acquisition device (such as a 360-degree panoramic camera, etc.) first needs to receive the venue scene recognition instruction (a timed image acquisition cycle can be set in the image acquisition device, such as 10min, 30min, 1h, 2h, 12h, 24h, etc., and of course other durations can be flexibly set according to user needs, and are not limited to the above examples), and then acquire the image in the direction it is aimed at to obtain the current venue image, and then send the current venue image to the server for subsequent image recognition.

[0040] S120: The server recognizes the current venue image based on a pre-trained image recognition model to obtain the current venue type.

[0041] In this embodiment, after the server receives the current venue image, it can identify the current venue image based on the local image recognition model to determine the current venue type. For example, the image recognition model identifies several key objects in the current venue image, and the current venue type can be obtained by comprehensive analysis of the several key objects.

[0042] In one embodiment, the image recognition model is a multi-target detection model; Figure 3 As shown, step S120 includes:

[0043] S121, acquiring multiple target detection areas in the current site image based on the multi-target detection model, and determining a classification result corresponding to each target detection area;

[0044] S122: Determine the current venue type corresponding to the classification result set based on a classification result set composed of classification results corresponding to the multiple target detection areas and a local venue recognition knowledge base.

[0045] In this embodiment, the multi-target detection model specifically used may be a Yolo model (such as a Yolo V3 model, a Yolo V5 model, etc.), and the Yolo model may be used to locate the area where the object exists in the current site image. Figure 4 As shown, target detection areas 1 to 4 are identified in the current site image, and then classification results are determined for each target detection area based on the Yolo model. For example, target detection area 1 corresponds to device 1, target detection area 2 corresponds to device 2, target detection area 3 corresponds to device 3, and target detection area 4 corresponds to device 4. The above four classification results determine that device 1, device 2, device 3, and device 4 are included in the current site image, and device 1, device 2, device 3, and device 4 constitute a classification result set.

[0046] The classification result set is then substituted into the local site identification knowledge base and matched with the knowledge graph in the site identification knowledge base to determine whether there is a site type that includes the above-mentioned equipment 1-equipment 4. If there is a site type that includes the above-mentioned equipment 1-equipment 4, then the site type is determined to be the current site type corresponding to the classification result set, such as AA product production line, BB industrial equipment, etc.

[0047] In one embodiment, after step S120, the method further includes:

[0048] If the server determines that the current venue type is different from any of the preset venue identification types in the preset venue identification type set, then generating a positioning information acquisition instruction and sending it to the cloud server;

[0049] The current venue positioning information is received and sent by the cloud server and corresponds to the positioning information acquisition instruction, and the current venue type is determined based on the current venue positioning information.

[0050] In this embodiment, when the current venue type obtained by the server based on the received current venue image and identification is different from each preset venue identification type in the preset venue identification type set, for example, when the current venue identification type is a null value, it can be regarded as different from each preset venue identification type in the preset venue identification type set. At this time, a positioning information acquisition instruction can be generated and sent to the cloud server (this cloud server is different from the server. Its main function is to serve as a control center. Each server, each image acquisition device and each RFID reader group can upload its specific deployment positioning information in advance). Afterwards, the cloud server parses and obtains the positioning information acquisition instruction and obtains the corresponding current venue positioning information from the multiple positioning information pre-stored locally. Finally, the corresponding enterprise name is obtained in combination with the current venue positioning information, and the current venue type is determined based on its production and business scope and main product information. It can be seen that based on this method, when the current venue type cannot be directly determined by the current venue image, the current venue type is determined by positioning.

[0051] S130: The server obtains a current reader-writer reading strategy corresponding to the current venue type based on a preset reader-writer reading intelligent selection strategy, and sends the strategy to one of the target RFID readers in the RFID reader-writer group.

[0052] In this embodiment, after the current site type to which the RFID reading system is deployed at the corresponding location is determined in the server, the current reader-writer reading strategy corresponding to the current site type needs to be determined based on the preset reader-writer reading intelligent selection strategy. For example, multiple reader-writer reading strategies are stored locally in the server, and the reader-writer reading intelligent selection strategy can be used to determine a current reader-writer reading strategy from multiple reader-writer reading strategies in combination with the current site type as the reader-writer reading strategy to be deployed, and then the current reader-writer reading strategy is sent to one of the target RFID readers in the RFID reader group to be specifically configured and applied in the target RFID reader.

[0053] In one embodiment, if Figure 5 As shown, step S130 includes:

[0054] S131, determining the similarity between the applicable site type tag of each preset reader / writer reading strategy in a plurality of preset reader / writer reading strategies and the current site type based on the reader / writer reading intelligent selection strategy;

[0055] S132: Acquire a target applicable venue type tag having the greatest similarity to the current venue type, and acquire a reader / writer reading strategy corresponding to the target applicable venue type tag as the current reader / writer reading strategy.

[0056] In this embodiment, a plurality of preset reader / writer reading strategies are pre-set and stored locally on the server, and each preset reader / writer reading strategy can be pre-tagged, that is, each preset reader / writer reading strategy corresponds to at least one applicable venue type tag (it can be understood that some preset reader / writer reading strategies can also correspond to multiple applicable venue type tags). After the word vector corresponding to the current venue type is known, the similarity between the word vector corresponding to the applicable venue type tag of each preset reader / writer reading strategy and the word vector of the current venue type can be calculated (such as cosine similarity, etc.), and then the target applicable venue type tag with the maximum similarity with the current venue type is determined. Finally, the reader / writer reading strategy corresponding to the target applicable venue type tag is used as the current reader / writer reading strategy. It can be seen that based on the above method, the current reader / writer reading strategy can be quickly determined according to the current venue type.

[0057] S140: The target RFID reader of the RFID reader group reads all RFID tags in one group of the grouped RFID tags based on the current reader reading strategy within a first preset time period, determines a corresponding first reading efficiency index and sends it to the server.

[0058] In this embodiment, when one of the target RFID readers in the RFID reader group as the RFID reading system receives the current reader reading strategy sent by the server, it is necessary to perform a test to see whether it is applicable to the RFID reading system. Specifically, the target RFID reader performs at least one round of reading on all RFID tags in one group of the grouped RFID tags based on the current reader reading strategy within a first preset time period (each grouped RFID tag in the grouped RFID tags is specifically set on a specific device or material in the current site), and after completing the above reading, determines a first reading efficiency index and sends it to the server. By judging whether the first reading efficiency index exceeds the preset efficiency threshold, it is specifically judged whether the current reader reading strategy is applicable to the RFID reading system. It can be seen that based on the above method, the reading efficiency test of the current reader reading strategy can be quickly completed, so as to further determine whether to retain the current reader reading strategy.

[0059] In one embodiment, before step S140, the method further includes:

[0060] The target RFID reader of the RFID reader group completes the local read / write strategy configuration based on the current reader read strategy;

[0061] like Figure 6 As shown, step S140 includes:

[0062] S141, the target RFID reader / writer obtains a target grouped RFID tag corresponding to the target RFID reader / writer from the grouped RFID tags; wherein the grouped RFID tags include a plurality of grouped RFID tags, and each grouped RFID tag corresponds to one RFID reader / writer;

[0063] S142, the target RFID reader reads each RFID tag in the target group RFID tags within the first preset time period based on the current reader reading strategy, and obtains a reading result corresponding to each RFID tag in the target group RFID tags;

[0064] S143, based on the reading result corresponding to each RFID tag in the target group of RFID tags and a preset reading efficiency determination strategy, obtaining a tag reading efficiency index corresponding to each RFID tag in the target group of RFID tags and correspondingly determining the first reading efficiency index;

[0065] S144. Send the first reading efficiency indicator to the server.

[0066] In this embodiment, first, the target RFID reader obtains the corresponding target group RFID tag from the grouped RFID tag (generally, the RFID electronic tags of the site corresponding to the current site image can be pre-divided into multiple groups in the server according to a preset grouping strategy, and each group RFID tag in the grouped RFID tags is mapped to a corresponding RFID reader).

[0067] Then, the target RFID reader performs at least one round of reading on each RFID tag in the target group RFID tags within the first preset time period based on the current reader reading strategy. Wherein, because the first preset time period may exceed the time taken for each RFID tag in the target group RFID tags to be read once, in order to improve the stability of the test process, the target RFID reader may perform multiple rounds of reading on each RFID tag in the target group RFID tags within the first preset time period, and then accurately determine the first reading efficiency index based on the multiple rounds of reading.

[0068] Specifically, the target RFID reader reads each RFID tag in the target group RFID tags within a first preset time period to obtain a reading result corresponding to each RFID tag in the target group RFID tags. After the target RFID reader reads each RFID tag in the target group RFID tags once to obtain a reading sub-result, all of them will be stored in the target RFID reader. If the same RFID tag is read multiple times, each reading sub-result will also be stored in the target RFID reader and constitute a reading result corresponding to the RFID tag. After each RFID tag is read by the target RFID reader, the obtained reading result will not only record the data information originally stored in the RFID tag, but also record the reading success rate and average reading time of the RFID tag. For example, an RFID tag is read three times by the target RFID reader, each time it is read successfully and the total time taken for the three reads is 0.9s. The data information originally stored in the RFID tag is obtained three times in the target RFID reader, and the data information originally stored in the RFID tag obtained each time is exactly the same. In the above case, it can be determined that the reading success rate of the RFID tag is 100% and the average reading time is 0.3s.

[0069] After obtaining the reading results corresponding to each RFID tag in the target group RFID tags, the tag reading efficiency index corresponding to each RFID tag in the target group RFID tags is obtained in combination with the reading efficiency determination strategy, and the first reading efficiency index is finally comprehensively determined. For example, the tag reading efficiency index corresponding to each RFID tag in the target group RFID tags can be averaged to determine the first reading efficiency index. Finally, the target RFID reader sends the first reading efficiency index to the server. It can be seen that based on the above method, the data reading and comprehensive reading efficiency index determination of each RFID tag in the target group RFID tags can be quickly completed within the first preset time.

[0070] In one embodiment, if Figure 7 As shown, step S143 includes:

[0071] S1431, obtaining the reading success rate and average reading time of the corresponding reading result of each RFID tag in the target group RFID tags;

[0072] S1432, if it is determined that the reading success rate of the corresponding reading result of the RFID tag is the first preset success rate and the average reading time is less than the first preset time, determine the tag reading efficiency index of the RFID tag based on the reading efficiency determination strategy and the average reading time; wherein the formula of the reading efficiency determination strategy is the tag reading efficiency index of the RFID tag = 1 / average reading time;

[0073] S1433. Obtain an average value of the tag reading efficiency of the tag reading efficiency index corresponding to each RFID tag in the target group of RFID tags, and use the average value as the first reading efficiency index.

[0074] In this embodiment, after the target RFID reader has completed the acquisition of the reading success rate and the average reading time of the corresponding reading result of each RFID tag in the target group RFID tag, it can be determined whether the reading success rate of the corresponding reading result of each RFID tag is the first preset success rate (such as the first preset success rate is set to 100%). If it is determined that the reading success rate corresponding to each RFID tag in the target group RFID tag is the first preset success rate and the average reading time is less than the first preset time, the target RFID reader has completed multiple rounds of successful reading for each RFID tag in the target group RFID tag. At this time, the determination of the tag reading efficiency index of a certain RFID tag is taken as an example. After determining the average reading time of the certain RFID tag (its unit can also be equivalent to seconds / piece), its reciprocal is directly used as the tag reading efficiency index of the RFID tag (its unit can be recorded as pieces / second). After determining the tag reading efficiency index corresponding to each RFID tag in the target group RFID tag, the average value of the corresponding multiple tag reading efficiency indexes is calculated, which can be used as the first reading efficiency index. It can be seen that based on the above method, the first reading efficiency index of the target RFID reader can be quickly determined.

[0075] S150: If the server determines that the first reading efficiency index does not exceed a preset efficiency threshold, the server determines an adjusted reading strategy based on a preset dynamic adjustment strategy and sends the strategy to each RFID reader in the RFID reader group.

[0076] In this embodiment, if the server determines that the first reading efficiency index does not exceed the preset efficiency threshold, it means that the current reader-writer reading strategy is not suitable for the RFID reading system. At this time, the adjusted reading strategy can be further determined by the dynamic adjustment strategy, and the adjusted reading strategy is used to replace the current reader-writer reading strategy and deployed in each RFID reader-writer in the RFID reader-writer group. After each RFID reader-writer in the RFID reader-writer group receives the adjusted reading strategy, the configuration and deployment of the adjusted reading strategy is completed in each RFID reader-writer.

[0077] Of course, if the server determines that the first reading efficiency index exceeds the preset efficiency threshold, it means that the current reader / writer reading strategy is applicable to the RFID reading system. At this time, there is no need to determine the adjusted reading strategy based on the dynamic adjustment strategy, but to perform the following steps: If the server determines that the first reading efficiency index exceeds the preset efficiency threshold, the current reader / writer reading strategy is sent to each RFID reader / writer in the RFID reader / writer group.

[0078] In one embodiment, step S150 includes:

[0079] Acquire a general read strategy corresponding to the dynamic adjustment strategy, and use the general read strategy as the adjusted read strategy and send it to each RFID reader in the RFID reader group;

[0080] Alternatively, step S150 includes:

[0081] Based on the dynamic adjustment strategy, a target reader / writer reading strategy having an optimized strategy mapping relationship with the current reader / writer reading strategy is obtained from the multiple preset reader / writer reading strategies, and the target reader / writer reading strategy is used as the adjusted reading strategy and sent to each RFID reader / writer in the RFID reader / writer group.

[0082] In this embodiment, at least two methods can be used to dynamically adjust and replace the current reader-writer reading strategy. The first method is to obtain a general reading strategy corresponding to the dynamic adjustment strategy, and use the general reading strategy as the adjusted reading strategy and send it to each RFID reader-writer in the RFID reader-writer group; the second method is to obtain a target reader-writer reading strategy that has an optimized strategy mapping relationship with the current reader-writer reading strategy from the multiple preset reader-writer reading strategies. Generally, the target reader-writer reading strategy has a similar relationship with the current reader-writer reading strategy, but some parameters are different. At this time, the target reader-writer reading strategy is used as the adjusted reading strategy and sent to each RFID reader-writer in the RFID reader-writer group. It can be seen that based on the above method, the dynamic adjustment of the reading strategy in each RFID reader-writer in the RFID reader-writer group is realized.

[0083] S160: Each RFID reader in the RFID reader group reads the RFID tags that are not grouped in the grouped RFID tags based on the adjusted reading strategy, obtains RFID tag reading results, and sends them to the server.

[0084] In this embodiment, when each RFID reader in the RFID reader group completes the configuration of the adjusted reading strategy, it can start to read the RFID tags of the unread groups in the grouped RFID tags at least once, obtain the RFID tag reading results and send them to the server. At this time, the server has stored the reading results of all the grouped RFID tags in the grouped RFID tags, and the current round of RFID tag reading has been completed. After that, the respective data analysis applications can be performed based on the RFID tag reading results.

[0085] It can be seen that the embodiment of the method can determine the current site type and the current reader reading strategy based on image recognition, and when all RFID tags in one group of the grouped RFID tags are read and it is determined that the first reading efficiency index does not exceed the preset efficiency threshold, it can also determine the adjusted reading strategy based on the dynamic adjustment strategy and send it to each RFID reader in the RFID reader group for subsequent reading processing, so that the reading strategy in the RFID reader can be intelligently and dynamically adjusted.

[0086] Figure 8 is a schematic block diagram of a reading system provided by an embodiment of the present invention. Figure 8 As shown, corresponding to the above RFID system dynamic reading method based on intelligent decision-making, the present invention also provides a reading system 100. Figure 1 and Figure 8 As shown, the reading system 100 is configured in an RFID reading system, and the RFID reading system includes a server 10, an image acquisition device 20, and an RFID reader-writer group 30, and the image acquisition device 20 and the plurality of RFID readers included in the RFID reader-writer group 30 are all communicatively connected to the server 10. The server 10 may be an edge server that is no more than a first preset distance (such as 100 m) away from the deployment location of the image acquisition device 20 and the RFID reader-writer group 30, or may be a cloud server that is more than the first preset distance away.

[0087] The image acquisition device 20 is used to respond to the venue scene recognition instruction, obtain the current venue image corresponding to the venue scene recognition instruction, and send it to the server.

[0088] In this embodiment, after the RFID reading system is deployed in a certain venue (such as a production workshop where an industrial production line is located), in order to quickly determine the reader reading strategy that needs to be deployed by the RFID reader group, the image acquisition device (such as a 360-degree panoramic camera, etc.) first needs to receive the venue scene recognition instruction (a timed image acquisition cycle can be set in the image acquisition device, such as 10min, 30min, 1h, 2h, 12h, 24h, etc., and of course other durations can be flexibly set according to user needs, and are not limited to the above examples), and then acquire the image in the direction it is aimed at to obtain the current venue image, and then send the current venue image to the server for subsequent image recognition.

[0089] The server 10 is used to identify the current venue image based on a pre-trained image recognition model to obtain the current venue type.

[0090] In this embodiment, after the server receives the current venue image, it can identify the current venue image based on the local image recognition model to determine the current venue type. For example, the image recognition model identifies several key objects in the current venue image, and the current venue type can be obtained by comprehensive analysis of the several key objects.

[0091] In one embodiment, the image recognition model is a multi-target detection model; the server 10 is specifically used for:

[0092] Acquire multiple target detection areas in the current site image based on the multi-target detection model, and determine a classification result corresponding to each target detection area;

[0093] Based on a classification result set composed of classification results corresponding to the plurality of target detection areas respectively and a local venue recognition knowledge base, the current venue type corresponding to the classification result set is determined.

[0094] In this embodiment, the multi-target detection model specifically used may be a Yolo model (such as a Yolo V3 model, a Yolo V5 model, etc.), and the Yolo model may be used to locate the area where the object exists in the current site image. Figure 4 As shown, target detection areas 1 to 4 are identified in the current site image, and then classification results are determined for each target detection area based on the Yolo model. For example, target detection area 1 corresponds to device 1, target detection area 2 corresponds to device 2, target detection area 3 corresponds to device 3, and target detection area 4 corresponds to device 4. The above four classification results determine that device 1, device 2, device 3, and device 4 are included in the current site image, and device 1, device 2, device 3, and device 4 constitute a classification result set.

[0095] The classification result set is then substituted into the local site identification knowledge base and matched with the knowledge graph in the site identification knowledge base to determine whether there is a site type that includes the above-mentioned equipment 1-equipment 4. If there is a site type that includes the above-mentioned equipment 1-equipment 4, then the site type is determined to be the current site type corresponding to the classification result set, such as AA product production line, BB industrial equipment, etc.

[0096] In one embodiment, the server 10 is further used for:

[0097] If it is determined that the current venue type is different from any of the preset venue identification types in the preset venue identification type set, generating a positioning information acquisition instruction and sending it to the cloud server;

[0098] The current venue positioning information is received and sent by the cloud server and corresponds to the positioning information acquisition instruction, and the current venue type is determined based on the current venue positioning information.

[0099] In this embodiment, when the current venue type obtained by the server based on the received current venue image and identification is different from each preset venue identification type in the preset venue identification type set, for example, when the current venue identification type is a null value, it can be regarded as different from each preset venue identification type in the preset venue identification type set. At this time, a positioning information acquisition instruction can be generated and sent to the cloud server (this cloud server is different from the server. Its main function is to serve as a control center. Each server, each image acquisition device and each RFID reader group can upload its specific deployment positioning information in advance). Afterwards, the cloud server parses and obtains the positioning information acquisition instruction and obtains the corresponding current venue positioning information from the multiple positioning information pre-stored locally. Finally, the corresponding enterprise name is obtained in combination with the current venue positioning information, and the current venue type is determined based on its production and business scope and main product information. It can be seen that based on this method, when the current venue type cannot be directly determined by the current venue image, the current venue type is determined by positioning.

[0100] The server 10 is further configured to obtain a current reader-writer reading strategy corresponding to the current venue type based on a preset reader-writer reading intelligent selection strategy, and send the strategy to one of the target RFID readers in the RFID reader-writer group.

[0101] In this embodiment, after the current site type to which the RFID reading system is deployed at the corresponding location is determined in the server, the current reader-writer reading strategy corresponding to the current site type needs to be determined based on the preset reader-writer reading intelligent selection strategy. For example, multiple reader-writer reading strategies are stored locally in the server, and the reader-writer reading intelligent selection strategy can be used to determine a current reader-writer reading strategy from multiple reader-writer reading strategies in combination with the current site type as the reader-writer reading strategy to be deployed, and then the current reader-writer reading strategy is sent to one of the target RFID readers in the RFID reader group to be specifically configured and applied in the target RFID reader.

[0102] In one embodiment, the server 10 is further specifically configured to:

[0103] Determine the similarity between the applicable site type tag of each preset reader-writer reading strategy in a plurality of preset reader-writer reading strategies and the current site type based on the reader-writer reading intelligent selection strategy;

[0104] A target applicable venue type tag having the greatest similarity to the current venue type is obtained, and a reader / writer reading strategy corresponding to the target applicable venue type tag is obtained as the current reader / writer reading strategy.

[0105] In this embodiment, a plurality of preset reader / writer reading strategies are pre-set and stored locally on the server, and each preset reader / writer reading strategy can be pre-tagged, that is, each preset reader / writer reading strategy corresponds to at least one applicable venue type tag (it can be understood that some preset reader / writer reading strategies can also correspond to multiple applicable venue type tags). After the word vector corresponding to the current venue type is known, the similarity between the word vector corresponding to the applicable venue type tag of each preset reader / writer reading strategy and the word vector of the current venue type can be calculated (such as cosine similarity, etc.), and then the target applicable venue type tag with the maximum similarity with the current venue type is determined. Finally, the reader / writer reading strategy corresponding to the target applicable venue type tag is used as the current reader / writer reading strategy. It can be seen that based on the above method, the current reader / writer reading strategy can be quickly determined according to the current venue type.

[0106] The target RFID reader of the RFID reader group 30 is used to read all RFID tags in one group of the grouped RFID tags based on the current reader reading strategy within a first preset time period, and determine the corresponding first reading efficiency index and send it to the server.

[0107] In this embodiment, when one of the target RFID readers in the RFID reader group as the RFID reading system receives the current reader reading strategy sent by the server, it is necessary to perform a test to see whether it is applicable to the RFID reading system. Specifically, the target RFID reader performs at least one round of reading on all RFID tags in one group of the grouped RFID tags based on the current reader reading strategy within a first preset time period (each grouped RFID tag in the grouped RFID tags is specifically set on a specific device or material in the current site), and after completing the above reading, determines a first reading efficiency index and sends it to the server. By judging whether the first reading efficiency index exceeds the preset efficiency threshold, it is specifically judged whether the current reader reading strategy is applicable to the RFID reading system. It can be seen that based on the above method, the reading efficiency test of the current reader reading strategy can be quickly completed, so as to further determine whether to retain the current reader reading strategy.

[0108] In one embodiment, the target RFID reader of the RFID reader group 30 is further used to complete the local read / write policy configuration based on the current reader read policy;

[0109] The target RFID reader is specifically used for:

[0110] Acquire a target grouped RFID tag corresponding to the target RFID reader-writer from the grouped RFID tags; wherein the grouped RFID tags include a plurality of grouped RFID tags, and each grouped RFID tag corresponds to one RFID reader-writer;

[0111] Based on the current reader-writer reading strategy, read each RFID tag in the target group RFID tags within the first preset time period to obtain a reading result corresponding to each RFID tag in the target group RFID tags;

[0112] Based on the reading result corresponding to each RFID tag in the target group of RFID tags and a preset reading efficiency determination strategy, obtaining a tag reading efficiency index corresponding to each RFID tag in the target group of RFID tags and correspondingly determining the first reading efficiency index;

[0113] The first reading efficiency indicator is sent to the server.

[0114] In this embodiment, first, the target RFID reader obtains the corresponding target group RFID tag from the grouped RFID tag (generally, the RFID electronic tags of the site corresponding to the current site image can be pre-divided into multiple groups in the server according to a preset grouping strategy, and each group RFID tag in the grouped RFID tags is mapped to a corresponding RFID reader).

[0115] Then, the target RFID reader performs at least one round of reading on each RFID tag in the target group RFID tags within the first preset time period based on the current reader reading strategy. Wherein, because the first preset time period may exceed the time taken for each RFID tag in the target group RFID tags to be read once, in order to improve the stability of the test process, the target RFID reader may perform multiple rounds of reading on each RFID tag in the target group RFID tags within the first preset time period, and then accurately determine the first reading efficiency index based on the multiple rounds of reading.

[0116] Specifically, the target RFID reader reads each RFID tag in the target group RFID tags within a first preset time period to obtain a reading result corresponding to each RFID tag in the target group RFID tags. After the target RFID reader reads each RFID tag in the target group RFID tags once to obtain a reading sub-result, all of them will be stored in the target RFID reader. If the same RFID tag is read multiple times, each reading sub-result will also be stored in the target RFID reader and constitute a reading result corresponding to the RFID tag. After each RFID tag is read by the target RFID reader, the obtained reading result will not only record the data information originally stored in the RFID tag, but also record the reading success rate and average reading time of the RFID tag. For example, an RFID tag is read three times by the target RFID reader, each time it is read successfully and the total time taken for the three reads is 0.9s. The data information originally stored in the RFID tag is obtained three times in the target RFID reader, and the data information originally stored in the RFID tag obtained each time is exactly the same. In the above case, it can be determined that the reading success rate of the RFID tag is 100% and the average reading time is 0.3s.

[0117] After obtaining the reading results corresponding to each RFID tag in the target group RFID tags, the tag reading efficiency index corresponding to each RFID tag in the target group RFID tags is obtained in combination with the reading efficiency determination strategy, and the first reading efficiency index is finally comprehensively determined. For example, the tag reading efficiency index corresponding to each RFID tag in the target group RFID tags can be averaged to determine the first reading efficiency index. Finally, the target RFID reader sends the first reading efficiency index to the server. It can be seen that based on the above method, the data reading and comprehensive reading efficiency index determination of each RFID tag in the target group RFID tags can be quickly completed within the first preset time.

[0118] In one embodiment, the target RFID reader is further specifically used for:

[0119] Obtaining the reading success rate and average reading time of the corresponding reading result of each RFID tag in the target group RFID tags;

[0120] If it is determined that the reading success rate of the corresponding reading result of the RFID tag is a first preset success rate and the average reading time is less than the first preset time, then the tag reading efficiency index of the RFID tag is determined based on the reading efficiency determination strategy and the average reading time; wherein the formula of the reading efficiency determination strategy is the tag reading efficiency index of the RFID tag = 1 / average reading time;

[0121] An average value of the tag reading efficiency of the tag reading efficiency index corresponding to each RFID tag in the target group of RFID tags is obtained and used as the first reading efficiency index.

[0122] In this embodiment, after the target RFID reader has completed the acquisition of the reading success rate and the average reading time of the corresponding reading result of each RFID tag in the target group RFID tag, it can be determined whether the reading success rate of the corresponding reading result of each RFID tag is the first preset success rate (such as the first preset success rate is set to 100%). If it is determined that the reading success rate corresponding to each RFID tag in the target group RFID tag is the first preset success rate and the average reading time is less than the first preset time, the target RFID reader has completed multiple rounds of successful reading for each RFID tag in the target group RFID tag. At this time, the determination of the tag reading efficiency index of a certain RFID tag is taken as an example. After determining the average reading time of the certain RFID tag (its unit can also be equivalent to seconds / piece), its reciprocal is directly used as the tag reading efficiency index of the RFID tag (its unit can be recorded as pieces / second). After determining the tag reading efficiency index corresponding to each RFID tag in the target group RFID tag, the average value of the corresponding multiple tag reading efficiency indexes is calculated, which can be used as the first reading efficiency index. It can be seen that based on the above method, the first reading efficiency index of the target RFID reader can be quickly determined.

[0123] The server 10 is further configured to determine an adjusted reading strategy based on a preset dynamic adjustment strategy and send the adjusted reading strategy to each RFID reader in the RFID reader group if it is determined that the first reading efficiency index does not exceed a preset efficiency threshold.

[0124] In this embodiment, if the server determines that the first reading efficiency index does not exceed the preset efficiency threshold, it means that the current reader-writer reading strategy is not suitable for the RFID reading system. At this time, the adjusted reading strategy can be further determined by the dynamic adjustment strategy, and the adjusted reading strategy is used to replace the current reader-writer reading strategy and deployed in each RFID reader-writer in the RFID reader-writer group. After each RFID reader-writer in the RFID reader-writer group receives the adjusted reading strategy, the configuration and deployment of the adjusted reading strategy is completed in each RFID reader-writer.

[0125] Of course, if the server determines that the first reading efficiency index exceeds the preset efficiency threshold, it means that the current reader / writer reading strategy is applicable to the RFID reading system. At this time, there is no need to determine the adjusted reading strategy based on the dynamic adjustment strategy, but to perform the following steps: If the server determines that the first reading efficiency index exceeds the preset efficiency threshold, the current reader / writer reading strategy is sent to each RFID reader / writer in the RFID reader / writer group.

[0126] In one embodiment, the server 10 is further specifically configured to:

[0127] Acquire a general read strategy corresponding to the dynamic adjustment strategy, and use the general read strategy as the adjusted read strategy and send it to each RFID reader in the RFID reader group;

[0128] Alternatively, the server 10 is further specifically configured to:

[0129] Based on the dynamic adjustment strategy, a target reader / writer reading strategy having an optimized strategy mapping relationship with the current reader / writer reading strategy is obtained from the multiple preset reader / writer reading strategies, and the target reader / writer reading strategy is used as the adjusted reading strategy and sent to each RFID reader / writer in the RFID reader / writer group.

[0130] In this embodiment, at least two methods can be used to dynamically adjust and replace the current reader-writer reading strategy. The first method is to obtain a general reading strategy corresponding to the dynamic adjustment strategy, and use the general reading strategy as the adjusted reading strategy and send it to each RFID reader-writer in the RFID reader-writer group; the second method is to obtain a target reader-writer reading strategy that has an optimized strategy mapping relationship with the current reader-writer reading strategy from the multiple preset reader-writer reading strategies. Generally, the target reader-writer reading strategy has a similar relationship with the current reader-writer reading strategy, but some parameters are different. At this time, the target reader-writer reading strategy is used as the adjusted reading strategy and sent to each RFID reader-writer in the RFID reader-writer group. It can be seen that based on the above method, the dynamic adjustment of the reading strategy in each RFID reader-writer in the RFID reader-writer group is realized.

[0131] Each RFID reader in the RFID reader group 30 is used to read the RFID tags of the unread groups in the grouped RFID tags based on the adjusted reading strategy, obtain the RFID tag reading results, and send them to the server.

[0132] In this embodiment, when each RFID reader in the RFID reader group completes the configuration of the adjusted reading strategy, it can start to read the RFID tags of the unread groups in the grouped RFID tags at least once, obtain the RFID tag reading results and send them to the server. At this time, the server has stored the reading results of all the grouped RFID tags in the grouped RFID tags, and the current round of RFID tag reading has been completed. After that, the respective data analysis applications can be performed based on the RFID tag reading results.

[0133] It can be seen that the implementation example of the system can determine the current site type and the current reader reading strategy based on image recognition, and based on reading all RFID tags in one group of the grouped RFID tags and determining that the first reading efficiency index does not exceed the preset efficiency threshold, it can also determine the adjusted reading strategy based on the dynamic adjustment strategy and send it to each RFID reader in the RFID reader group for subsequent reading processing, so that the reading strategy in the RFID reader can be intelligently and dynamically adjusted.
