Description

Technical Field

[0001] This invention relates to an intelligent reusable turnover box based on RFID tags and its tracking method, and particularly to the field of turnover box technology. Background Technology

[0002] Turnover boxes, also known as logistics boxes or material boxes, are containers used for storing and moving materials. They facilitate cleaning, allow for easy movement of parts, and ensure neat stacking, thus simplifying management. Depending on the material, turnover boxes can be categorized into several types, including plastic, metal, and paper turnover boxes.

[0003] Turnover boxes are used in various warehouses, production sites and other occasions in logistics management. By using turnover boxes, enterprises can achieve universal and integrated management of logistics containers, improve logistics efficiency and reduce logistics costs. In addition, the use of turnover boxes can effectively reduce the damage of materials during handling and save a lot of labor costs.

[0004] In the current management model of turnover boxes, when customers unload products and return the turnover boxes, they need to return them one by one according to the source of the wholesale products and the holders of the turnover boxes, or return them when the product wholesaler sells the next batch of products. This not only brings great inconvenience to the recycling of turnover boxes, but also causes delays in the recycling time for product wholesalers, resulting in economic losses. When turnover boxes are used for live transport, they are simply transported, which means that the products need to be further sorted after arriving at the destination, which is a great waste of transportation time. Summary of the Invention

[0005] Purpose of the invention: One purpose is to propose an intelligent reusable container based on RFID tags to solve the above-mentioned problems in the prior art; a further purpose is to propose a system for implementing the above method.

[0006] Technical solution: An intelligent reusable turnover box based on RFID tags, comprising:

[0007] The enclosure includes a housing, a cover plate installed on top of the housing, RFID tags embedded in both sides of the housing, and a counting component. The counting component includes a pressure rod inserted into the housing. One side of the pressure rod is provided with multiple counting discs that are movably connected to the housing. The counting discs near the pressure rod have multiple slots that cooperate with the locking plates provided on the pressure rod. One side of the counting disc is also provided with a gear. A limiting pawl is provided between the gear and the housing. A first spring is provided between the limiting pawl and the housing. A second spring is provided between the pressure rod and the housing.

[0008] The box body is movably connected to the cover plate, and the pressure rod extends a certain distance towards the cover plate, with the pressure rod slidingly engaged with the box body.

[0009] A tracking method for intelligent reusable containers, comprising:

[0010] Step 1: First, set the sample base inside the box according to the shape of the sample provided by the customer;

[0011] Step two: Place the sample in the sample base inside the box, then embed the RFID tag inside the box, and record the sample classification, sample number, name information and the number of times the cover was opened for each individual sample into the RFID tag.

[0012] Step 3: Edit the RFID tag information based on the samples placed inside the box, and set the private and public keys for the edited information. The private key provides basic information about the samples inside the box, and the public key provides information about the box itself. After completing the editing of the sample information, set the box's storage location to prepare for the next transfer. The storage steps are as follows:

[0013] First, scan the RFID tags inside the box.

[0014] Generate container numbers based on the container's placement location.

[0015] The container numbers are entered into the warehouse, and the factory information of the containers is edited.

[0016] Step four: The transport vehicle transfers the boxes from the warehouse according to the quantity required by the customer. The transport vehicle calculates the number of times the lids are opened during transportation, obtains the factory and arrival quantities of the boxes during transportation, and the required temperature adjustment for the samples. The transport vehicle then feeds back the test data to the box supplier, and finally delivers the samples to their designated transfer location.

[0017] Step 5: Obtain the passwords for the public and private keys, and enter and verify the sample information based on the passwords for the private and public keys.

[0018] Step Six: The customer scans the RFID tags of the boxes arriving at the transfer location using the provided private and public key passwords to obtain information about the boxes and samples being inspected. This allows the customer to determine if the number of times the box was opened before leaving the factory matches the information recorded on the RFID tag or the counter. If they do not match, the box is deemed abnormal; if they match, the box is deemed intact, and the completed box is stored.

[0019] Step 7: Process the completed and stored containers for warehousing, record the container shipping information, and assign a corresponding inventory location to each container; the location assignment steps are as follows:

[0020] First, read the RFID tag number of the sample inside the box.

[0021] Samples from the mass reading were randomly selected for inspection, and the selected samples were placed in a temporary storage warehouse.

[0022] For samples that were not sampled, the storage location of the samples was set according to the password of the public key.

[0023] Step 8: Place the boxes identified as abnormal into the temporary sample storage warehouse. Inspectors will then retrieve samples from the temporary storage warehouse for testing. The testing steps are as follows:

[0024] First, swipe the inspector's IC card.

[0025] Find the location of the required sample in the temporary storage warehouse and select the sample.

[0026] Place the sample on the RFID tag reader / writer and read the sample number information from the RFID tag.

[0027] The sample inside the box is compared with the information on the RFID tag. If the sample number information on the RFID tag is incorrect, the sample number information on the RFID tag is modified according to the password of the private key, and the information of the inspection personnel is bound. If the sample is incorrect, it is transferred to the sample retention warehouse.

[0028] Step 9: After sample inspection, retain erroneous samples in the temporary storage warehouse. Destroy or replace expired or damaged samples. The processing steps are as follows:

[0029] First, swipe the inspector's IC card.

[0030] Place the sample on the RFID tag reader / writer and read the sample number information from the RFID tag.

[0031] Determine whether the sample is located in the sample retention room. If so, retain or destroy the sample. If not, transfer the sample to an unsampled storage location and link the information of the inspection personnel regarding destruction and retention.

[0032] Beneficial Effects: This invention proposes an intelligent reusable turnover box based on RFID tags and its tracking method. First, when the cover plate covers the turnover box, the pressure rod moves, causing the locking plate on the pressure rod to contact the locking slot, completing the rotation of the counting plate at a set angle and recording the number of times the turnover box is closed. When the cover plate opens, the spring provides tension, causing the pressure rod to reset. The limiting pawl controls the unidirectional rotation of the counting disk connected to the gear. After the counting disk rotates one revolution, it drives the adjacent counting disk to rotate at a certain angle, thus recording the number of times the turnover box is opened. During use, the internal structure of the turnover box is set according to the shape of the product, and the information of the RFID tags is edited. Then, a private key and public key are set to open or edit the RFID tags. The turnover box is inspected during transportation by a transport vehicle to ensure that it is stored in a suitable environment. The customer scans and identifies the RFID tags inside the turnover box using the provided private key and public key password, records the freight information of the turnover box, and enters the status and storage location information of the samples. After sample inspection, erroneous samples in the temporary storage warehouse are retained. Expired or damaged samples are destroyed or replaced. Attached Figure Description

[0042] The applicant argues that when existing customers unload products and return the turnover boxes, they need to return the boxes one by one according to the source of the wholesale products and the holders of the turnover boxes, or when the product wholesaler sells the next batch of products. This not only causes great inconvenience to the recycling of turnover boxes, but also delays the recycling time for product wholesalers, resulting in economic losses.

[0043] To address the problems existing in the prior art, this invention provides an intelligent reusable container based on RFID tags and its tracking method. This method enables the counting of the number of times the container's top cover is opened and prevents the cover from opening during transport.

[0044] The present solution will be further described in detail below through embodiments and with reference to the accompanying drawings.

One side of the pressure rod 2 is provided with multiple counting disks 3 that are movably connected to the housing 1. Multiple slots 32 are opened on the counting disks 3 near the pressure rod 2. The slots 32 cooperate with the locking plates provided on the pressure rod 2. A gear 4 is also provided on one side of the counting disks 3. A limiting claw 31 is provided between the gear 4 and the housing 1. A first spring is provided between the limiting claw 31 and the housing 1. A second spring is provided between the pressure rod 2 and the housing 1.

[0048] The box body 1 is movably connected to the cover plate 11, and the pressure rod 2 extends a certain distance towards the cover plate 11, and the pressure rod 2 is slidably engaged with the box body 1.

[0049] A tracking method for intelligent reusable containers, comprising:

[0050] Step 1: First, set up the sample base inside box 1 according to the sample shape provided by the customer;

[0051] Step 2: Place the sample in the sample base inside the box 1, then embed the RFID tag 5 inside the box 1, and record the sample classification, sample number, name information and the number of times the cover 11 has been opened into the RFID tag 5.

[0052] Step 3: Edit the information on RFID tag 5 based on the samples placed inside box 1, and set the private and public keys for the edited information. The private key provides basic information about the samples inside box 1, and the public key provides information about box 1 itself. After completing the editing of the sample information, set the storage location of box 1 to prepare for the next transfer. The storage steps are as follows:

[0053] First, scan the RFID tag 5 inside box 1.

[0054] Generate a box number based on the placement location of box 1.

[0055] Number and store container 1 in the warehouse, and complete the editing of the factory information for container 1.

[0056] Step four: The transport vehicle transfers the boxes 1 from the warehouse according to the quantity required by the customer. The transport vehicle calculates the number of times the cover 11 is opened during transportation, obtains the factory and arrival quantities of boxes 1 during transportation, and the temperature adjustment required for the samples. The transport vehicle then feeds back the test data to the box 1 supplier, and finally delivers the samples to their designated transfer location.

[0057] Step 5: Obtain the passwords for the public and private keys, and enter and verify the sample information based on the passwords for the private and public keys.

[0058] Step 6: The customer scans the RFID tag 5 of the box 1 that has arrived at the transfer location using the provided private key and public key password to obtain the information of the box 1 and sample being inspected. The customer then checks whether the number of times the box 1 was opened before leaving the factory is consistent with the information recorded on the RFID tag 5 or the information on the counting disk 3. If they are inconsistent, the box 1 is determined to be abnormal. If they are consistent, the box 1 is determined to be intact, and the completed box 1 is stored.

[0059] Step 7: For boxes 1 that have been completed and need to be stored, perform warehousing processing, record the shipping information of boxes 1, and assign corresponding inventory location information to each box 1; the location assignment steps are as follows:

[0060] First, read the RFID tag number of the sample inside box 1.

[0061] Samples from the mass reading were randomly selected for inspection, and the selected samples were placed in a temporary storage warehouse.

[0062] For samples that were not sampled, the storage location of the samples was set according to the password of the public key.

[0063] Step 8: Place the box 1 identified as abnormal into the temporary sample storage warehouse. The inspectors will then retrieve a sample from the temporary storage warehouse for testing. The testing steps are as follows:

[0064] First, swipe the inspector's IC card.

[0065] Find the location of the required sample in the temporary storage warehouse and select the sample.

[0066] Place the sample on the RFID tag 5 reader / writer device and read the sample number information from the RFID tag 5.

[0067] The sample inside box 1 is compared with the information on RFID tag 5. If the sample number information on RFID tag 5 is incorrect, the sample number information on RFID tag 5 is modified according to the password of the private key, and the inspection personnel information is bound. If the sample is incorrect, it is transferred to the sample retention warehouse.

[0068] Step 9: After sample inspection, retain erroneous samples in the temporary storage warehouse. Destroy or replace expired or damaged samples. The processing steps are as follows:

[0069] First, swipe the inspector's IC card.

[0070] Place the sample on the RFID tag 5 reader / writer device and read the sample number information from the RFID tag 5.

[0071] Determine whether the sample is located in the sample retention room. If so, retain or destroy the sample. If not, transfer the sample to an unsampled storage location and link the information of the inspection personnel regarding destruction and retention.

[0072] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
