[0028] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0029] Example 1, please refer to Figure 1-2 The present invention provides a technical solution: an intelligent radio frequency door for product entry and exit, the intelligent radio frequency door includes a door frame 1, and a controller 11 is installed on the top of the door frame 1. The controller 11 is used to control the execution of relevant instructions for product entry and exit.
[0030] The gantry 1 is U-shaped, and both sides of the bottom of the gantry 1 are movably connected with casters, which can be adjusted according to actual work needs and site environment to adjust the deployment of the radio frequency door, thus having deployment flexibility; the middle part of the gantry 1 is used for monitoring the entry and exit of metered products.
[0031] refer to Figure 1Several reading and writing units 2 are respectively set on both sides of the inner wall of the gantry 1. The reading and writing unit 2 consists of an RFID reader and a radio frequency antenna. RFID stands for Radio Frequency Identification, which is a wireless communication technology that uses radio waves to automatically identify objects and collect data. Each metered product entering and leaving the warehouse is equipped with a tag. The reading and writing unit 2 can identify the tag and is connected to the control unit 11 through several reading and writing units 2. The RFID reader receives the instructions issued by the control unit 11 and transmits a radio frequency signal of a specific frequency band through the radio frequency antenna to form an electromagnetic field that is transmitted to the tag. The tag has a built-in tag antenna. Therefore, the tag antenna generates an induced current according to the received radio frequency signal to activate the chip inside the tag and modulate the stored information into the feedback signal. The feedback signal is sent to the RFID reader. The RFID reader receives the feedback signal and decodes it to obtain the stored information of the tag. The stored information after reading is transmitted to the control unit 11 for further processing and analysis.
[0032] Therefore, when a metering product with a tag enters or leaves the warehouse, the reading and writing unit 2 can effectively receive and process the stored data on the tag of the metering product by sensing the corresponding tag. This data is used for product identification and includes the asset number, category type, and product parameters of the metering product.
[0033] The two reading / writing units 2 are staggered vertically to ensure comprehensive reading and writing of the product label and complete data acquisition.
[0034] A set of first identification cameras 3 are installed on one side of the inner wall of the gantry 1. The first identification cameras 3 are staggered with the reading and writing unit 2 on the same side. Specifically, the first identification cameras 3 identify the barcode on the box, accurately identify the box information, and verify it with the measurement product information. Two photoelectric transmitters 5 are arranged in the middle of the inner wall of the gantry 1 on the same side along the product entry and exit direction. Photoelectric receivers 10 are arranged in the middle of the inner wall of the gantry 1 on the opposite side, corresponding to the positions of the two photoelectric transmitters 5. The photoelectric transmitters 5 emit infrared signals, and the photoelectric receivers 10 are used to receive infrared signals. When the two photoelectric transmitters 5 emit infrared signals simultaneously, the photoelectric receivers 10 receive their respective infrared signals. The first identification camera 3, the photoelectric transmitters 5, and the photoelectric receivers 10 are all connected to the control unit 11.
[0035] When the container holding the metered product enters below the gantry 1, one of the signal transmissions is first cut off. The in / out direction is determined by the photoelectric receiver 10, which receives the first signal cut-off. For example, refer to... Figure 1X represents the outbound direction, and the opposite represents the inbound direction. Before the measured product is ready to leave the warehouse, the photoelectric transmitter 5 simultaneously transmits infrared signals to the photoelectric receiver 10. The photoelectric transmitter 5 away from the outbound direction will disconnect the signal with the photoelectric receiver 10. The photoelectric receiver 10 will feed back the signal disconnection data to the controller 11. When the measured product moves to the position where the infrared signal between the photoelectric transmitter 5 and the photoelectric receiver 10 near the outbound direction is cut off, the photoelectric receiver 10 near the outbound direction will feed back the signal disconnection data to the controller 11. The outbound and inbound processes are determined by the time feedback sequence of the two sets of signal disconnections.
[0036] Furthermore, an auxiliary light source 4 is arrayed on the inner wall of the gantry 1 on the same side as the first identification camera 3 to improve the shooting clarity of the first identification camera 3.
[0037] Furthermore, a set of verification components is installed on the outer wall side of the gantry 1 in the direction of entry and exit to determine the entry and exit tasks and operation authentication. The verification components are connected to the control unit 11 to improve the accuracy of entry and exit instructions and facilitate the traceability of subsequent processes. Specifically, the verification components include a touch screen 6, a second identification camera 7, and a barcode scanner 8. The second identification camera 7 is used to verify the user's identity, the touch screen 6 is used to check the working status of the radio frequency gate and determine the entry and exit tasks, and the barcode scanner 8 is used to assist the second identification camera 7 in identifying the user's identity.
[0038] An alarm device 9 is installed on the top of the gantry 1. The alarm device 9 includes an alarm light and a buzzer. The alarm device 9 is connected to the control unit 11 by signal to execute an alarm procedure when abnormal operation occurs.
[0039] The control unit 11 is connected to a processor via an intranet signal. The processor is used to receive, send, and adjust operation instructions to the control unit 11 to ensure the effective execution of product entry and exit procedures.
[0040] In this embodiment, after the work order task for inbound / outbound is determined, the user first performs identity verification at the verification component, and then pushes the placed box under the door frame 1. The reading and writing unit 2 identifies the metered products inside the box, and the auxiliary light source 4 assists the first identification camera 3 in identifying the box barcode. The box information is verified with the metered product information to prevent misplacement or omission. The radio frequency door stops working only after the work order task is completed.
[0041] If the read / write unit 2 reads or writes to a device that is not within the scope of the work order, the alarm 9 will issue an abnormal alarm to notify the user to investigate the abnormality.
[0042] With the aforementioned intelligent RFID gate, intelligent identification and inventory of metered products are realized during entry and exit from the warehouse. It can also complete batch delivery into the warehouse, transfer and delivery between secondary warehouses, and delivery between secondary and tertiary warehouses. The handover speed is significantly improved compared to manual methods. With the read / write unit 2 and the first identification camera 3, the recognition and scanning accuracy of the device is also significantly improved, thus better meeting the user's needs.
[0043] Example 2, based on Example 1, provides a method for controlling intelligent radio frequency gates for product entry and exit:
[0044] S1: The processor generates an inbound / outbound work order for the metered products. The processor transmits the work order synchronously to the controller 11 via the intranet connection. The controller 11 then parses the tasks within the work order.
[0045] S2: Users can ensure that the RF gate is in a normal and usable state by clicking the status self-test button on the touch screen 6.
[0046] It should be noted that if the status self-check result is abnormal, troubleshooting and handling will be carried out; if it is normal, the inbound and outbound tasks will continue to be executed.
[0047] S3: Users log in and select and confirm work orders by clicking the work order selection button on the touch screen 6.
[0048] The primary purpose of user login is authentication, and the methods for user login include at least the following:
[0049] Login Method 1: Click the login button on the touch screen 6. The second recognition camera 7 verifies the user's identity through facial recognition and authorizes the user to log in and perform the work order confirmation process.
[0050] Login Method 2: Click the login button on the touch screen 6. The scanning terminal 8 uses the work permit to verify the user's identity and authorize the user to log in and execute the work order confirmation process. If the work permit is not worn and used by the user, it will also involve traceability issues. In addition, during the subsequent transportation process, if it is not operated by the user, the second recognition camera 7 will determine whether it is operated by the user. If it is not operated by the user, an alarm process will be executed.
[0051] Login Method 3: For content involving authorization by the user to others, authorization to others to perform product inbound / outbound procedures can only be done in addition to login method 1. Login method 2 does not have the authorization function. Specifically, by clicking the login button on the touch screen 6, the second recognition camera 7 performs facial recognition. In addition to the work order selection button, an authorization button is added. Clicking the authorization button associates other users. Other users are selected by combining their department and employee number. Then, the associated other users can perform inbound / outbound procedures. This setting is suitable for the inbound / outbound of large quantities of products.
[0052] S4: The user measures the entry and exit of products according to the work order content and prompts the user to place the products in the radio frequency identification area. Specifically, the product packaged in a box is pushed to the bottom of the gantry 1 using a trolley. The reading and writing unit 2 uses radio frequency identification technology to obtain the storage information on the tag. The stored information after reading the code is transmitted to the control unit 11 for verification with the work order content.
[0053] When the stored information is not the content on the work order, the touch screen 6 displays an abnormal product and the alarm 9 sounds an alarm.
[0054] The above stored information includes, but is not limited to, asset number, category type, wiring method, voltage and current;
[0055] The work order content includes, but is not limited to, work order number, work order name, and type of equipment entering or leaving the warehouse.
[0056] S5: The first identification camera 3 identifies the barcode on the box, and the identified box information is transmitted to the control unit 11. The control unit 11 can check the packaging product information corresponding to the box with the product storage information obtained in S4, such as whether the category type is consistent, to avoid the problem of misplacement of products. On the basis of misplacement, it can also quickly check the box corresponding to the product.
[0057] When misplacement occurs, alarm device 9 will execute the alarm procedure.
[0058] S6: The radio frequency gate will continue the radio frequency identification process for a certain period of time, accompanied by a prompt sound. Clicking the "View Details" button on the touch screen 6 will display the list of identified items.
[0059] The controller 11 classifies and statistically analyzes the acquired product storage information, compares it with the work order content, calculates the percentage of products that have been identified, and updates the list of identified products and the list of unidentified products in real time.
[0060] S7: During the alarm process, the screen of the touch screen 6 displays an exception handling button to show a detailed list of abnormal products;
[0061] In addition, abnormal products will be removed from the current inventory inflow and outflow products.
[0062] S8: After all products have been identified and scanned, the touch screen 6 will display all product details to be entered or exited. After the user confirms, the controller 11 will upload the product details to the processor.
[0063] Under this control method, the product inbound and outbound processes are carried out in an orderly and effective manner, and abnormal products can be eliminated during the inbound and outbound processes. This not only greatly reduces manpower input, but also enables rapid and accurate updates to inventory information.
