Description

Technical Field

[0001] The present invention relates to the field of logistics and transportation, and in particular to a method and device for real-time tracking of intelligent egg trays based on RFID. Background Art

[0002] At present, food transportation generally does not require special containers, but egg raw materials generally need to be transported in egg trays, and disposable paper egg trays that cannot be recycled are usually used. The production process uses manual recording of information such as the source batch of fresh eggs, which can easily cause confusion in fresh egg batches and reduce overall production efficiency. In the prior art, RFID is usually applied to the field of food transportation, but it is usually solid food, while fresh eggs are mainly composed of liquid. In RFID technology, the wireless radio frequency application of RFID will be interfered by liquid, and the liquid in the egg has a special effect on the signal reception of RFID, especially in real-time tracking of moving liquid. At the same time, since the internal space of the fresh egg is not filled with liquid, factors such as internal mobility and extrudability will cause changes in the signal strength of the RFID signal when it penetrates these liquids. In addition, the stacking and placement of more than 30 layers of egg trays means that the liquid in each layer and each egg has an independent movement mode rather than a single continuous body of liquid moving uniformly (different from a large tank filled with liquid), which makes the positioning signal have a greater deviation.

[0003] Therefore, how to apply RFID in the transportation of fresh eggs to achieve real-time tracking of egg trays is a problem that needs to be solved urgently. Summary of the invention

[0063] It should be noted that in the embodiments of this specification, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0064] like Figure 1 The diagram shows a system for implementing a method for real-time tracking of multiple RFID-based smart egg trays in an embodiment of the present specification, including a processor 101 and multiple readers 102. The processor 101 and the readers 102 can communicate with each other through a network, which may include a bus network, a local area network (LAN), a wide area network (WAN), the Internet, or a combination thereof, and is connected to a website, a user device (such as a computing device), and a back-end system.

[0065] The reader / writer 102 can transmit the tag information of the RFID tag to the processor 101, and the processor 101 confirms the fresh egg information and logistics information of the egg tray according to the tag information, and then analyzes it to generate a real-time tracking report. Figure 1 What is shown is only an application environment provided by the embodiment of this specification. In actual application, other scenarios may also be included, and this specification does not limit them.

[0066] In view of the problems existing in the prior art, the embodiments of this specification provide a real-time tracking method for an intelligent egg tray based on RFID, which records all information of fresh eggs loaded on the RFID egg tray, so that the fresh eggs can be tracked, monitored and managed throughout the transportation process.

[0067] Figure 2 The flowchart of a method for real-time tracking of an intelligent egg tray based on RFID in an embodiment of the present specification is shown. The process of real-time tracking of an egg tray is described in this figure. The order of steps listed in the embodiment is only one way of executing the order of many steps and does not represent the only execution order. When the system or device product is executed in practice, it can be executed in the order of the method shown in the embodiment or the accompanying drawings or in parallel.

[0068] Specific as Figure 2 As shown, the method may include:

[0069] Step 201: stacking a plurality of egg trays with at least one RFID tag installed at different positions, and updating the tag information and inventory data of at least one RFID tag within the communication range according to the fresh egg information and logistics task information in the egg trays through an initial reader / writer;

[0070] Step 202: During the transportation process, the tag information of some of the RFID tags within the communication range is read by a reader / writer at a fixed position;

[0071] Step 203: the reader / writer obtains the fresh egg information according to the tag information, and compares the fixed position of the reader / writer and the fresh egg information with the inventory data;

[0072] Step 204: updating the location information of the egg tray in the inventory data according to the comparison result, and summarizing the updated location information and fresh egg information to generate a real-time tracking report.

[0073] By using the embodiments of the present specification, egg trays with at least one RFID tag installed at multiple different positions are stacked to ensure that at least one RFID tag can communicate and is not interfered by fresh eggs during reading and writing, and then the fresh egg information in the egg tray is written into the RFID tag by the initial reader / writer, and the fresh egg information and the corresponding logistics task information are stored in the inventory data; during the transportation process, the tag information of some of the RFID tags within the communication range is read by the reader / writer at a fixed position, so that the position passed by the egg tray with the RFID tag is obtained through the fixed position of the reader / writer, and the real-time position tracking of the egg tray is realized. At the same time, the reader / writer obtains the fresh egg information according to the tag information, and compares the fixed position of the reader / writer and the fresh egg information with the inventory data, so as to confirm that the transportation process of the egg tray conforms to the transportation process of the logistics task, and finally updates the location information of the egg tray in the inventory data according to the comparison result, and summarizes the updated location information and fresh egg information to generate a real-time tracking report. All the information of fresh eggs loaded on RFID egg trays can be recorded, so that the fresh eggs can be tracked, monitored and managed throughout the transportation process, thereby effectively improving the overall production and transportation efficiency. In addition, the egg trays can be reused, which is environmentally friendly and reduces transportation costs.

[0074] In the embodiment of this specification, in order to obtain the real-time position of the egg tray through the RFID tag, as shown in FIG. Figure 3 As shown, reading the tag information of some of the RFID tags within the communication range by a reader / writer at a fixed position further includes:

[0075] Step 301: The reader is fixed to a passage or a warehouse door for transporting the egg tray, and acquires tag information of the RFID tag during the transportation of the egg tray;

[0076] Step 302: at least one reader / writer obtains tag information of at least one RFID tag on the egg tray, and determines the real-time position of the egg tray according to the fixed position of the reader / writer.

[0077] The fixed-position reader / writer also includes a handheld reader / writer paired with the fixed position.

[0078] Specifically, each reader is located at a fixed position in the transport channel, and the location information of the egg tray carrying the RFID tag can be determined based on the tag information of the RFID tag obtained by the reader when the egg tray passes through this position. The multiple signals are received by multiple antennas arranged near the channel for transporting the multiple egg trays. For example, multiple antennas can be arranged on the walls on both sides of the channel, and one or more antennas can be arranged on each wall of the channel separating the production areas. Alternatively, a channel door or a channel door frame can be arranged in the channel as needed, and one or more antennas can be placed. The one or more antennas will be configured with one or more fixed RFID readers, which receive the information on the read tag through the reader and connect to the associated workstation to update the information on the intelligent egg tray management system in real time.

[0079] In the embodiments of this specification, since the reader is in a fixed position, and the wireless radio frequency application of RFID is disturbed by liquid, the liquid in the egg has a special effect on the signal reception of the RFID tag. Therefore, it is not guaranteed that the tag information of each RFID tag can be obtained during the tracking process. Similarly, it is not guaranteed that all RFID tags are updated when the tag information of the RFID tag is updated. Therefore, it is necessary to further judge some special situations that may occur, such as Figure 4 As shown, reading the tag information of some of the RFID tags within the communication range by a reader / writer at a fixed position further includes:

[0080] Step 401: comparing the label information, the real-time location of the egg tray and the logistics task information in the inventory data, if the corresponding relationship between the label information and the real-time location of the egg tray does not match the logistics task information, marking it as a suspicious label;

[0081] Step 402: Match the label information of the suspicious label with the historical logistics task information of the egg tray in the inventory data, and obtain the current logistics task information corresponding to the egg tray according to the matching result.

[0082] The historical logistics task information includes the fresh egg information of the egg tray in each logistics task.

[0083] Step 403: updating the tag information of the RFID tag according to the fresh egg information in the current logistics task information.

[0084] Specifically, the tag information on the egg tray and the real-time position of the egg tray are compared with the logistics task information in the inventory data. If the reader reads an RFID tag that has been updated in real time, the tag information and the real-time position of the egg tray should be consistent with the logistics task information. However, if the correspondence between the tag information and the real-time position of the egg tray is inconsistent with the logistics task information, it means that the reader may have read an RFID tag that has not been updated by the initial reader, that is, the tag information therein may still be the tag information when the egg tray transported the last batch of fresh eggs. Therefore, it is necessary to match the tag information with the historical tag information of the RFID tag in the inventory data, confirm the egg tray according to the tag information in the inventory data, and obtain the current tag information corresponding to the historical tag information according to the matching result.

[0085] In one embodiment of this specification, Figure 5 As shown, the smart egg tray placement method of installing at least one RFID tag at different positions on the egg tray further includes:

[0086] The egg tray is a plurality of egg trays with similar shapes stacked or separated by partitions, and arranged neatly in one or more layers according to a preset arrangement;

[0087] The RFID tags are installed at the same or different angles on multiple layers of the egg tray.

[0088] Multiple egg trays are placed on the pallet in a preset arrangement. Exemplarily, these egg trays can be neatly arranged into one or more layers, wherein egg tray partitions can be added, and each layer of items is neatly arranged into one or more rows, and one or more columns. Multiple egg trays have similar shapes, and can be placed in stacks in combination with each other in response to the size of fresh eggs. Wherein, each pallet and / or egg tray can have an RFID tag at any placement position, including: the center of the bottom of the pallet, the side of the pallet, the bottom of the egg tray, etc. By reading and writing the RFID tag, the relevant information of the item can be obtained and / or updated, wherein the fresh egg information at least includes: the location of the egg tray product, the entry and exit area, the origin of the fresh eggs, the batch, the weight, the production date, and the type of finished product. Wherein the fresh egg information can be synchronized to the RFID tag of the fresh egg finished product, which can be used to trace which fresh eggs are from after the subsequent production of the finished product, or to track the fresh egg information of the finished product.

[0089] In another embodiment of the present specification, the robotic arm can assign the fresh eggs to different conveyor belts according to their categories to complete logistics tasks based on the fresh egg information in the RFID tag, or transport the fresh eggs to different production areas for logistics tasks based on the fresh egg information, etc., so that the fresh eggs can be tracked, monitored and managed throughout the transportation process, thereby effectively improving the overall production and transportation efficiency.

[0090] Based on the same inventive concept, the embodiment of this specification also provides an intelligent egg tray real-time tracking device based on RFID, such as Figure 6 As shown, including:

[0091] The tag updating unit 601 is used to stack a plurality of egg trays with at least one RFID tag installed at different positions, and update the tag information and inventory data of at least one RFID tag within the communication range according to the fresh egg information and logistics task information in the egg trays through the initial reader / writer;

[0092] The tag reading unit 602 is used to read the tag information of some of the RFID tags within the communication range through a reader / writer at a fixed position during transportation;

[0093] A position comparison unit 603 is used for obtaining the fresh egg information according to the tag information by the reader / writer, and comparing the fixed position of the reader / writer and the fresh egg information with the inventory data;

[0094] The report generating unit 604 is used to update the location information of the egg tray in the inventory data according to the comparison result, and to summarize the updated location information and fresh egg information to generate a real-time tracking report.
