Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, and in particular to a car-type electronic tag identification device. Background Technology

[0002] In the warehousing and logistics industry, warehouse management has always been a major headache for businesses. Facing the repetitive daily inbound and outbound operations, warehouse management plays a crucial role in the entire supply chain. Failure to scientifically manage inbound, outbound, and inventory levels can lead to increased operating costs, low efficiency, and compromised service quality. Modern warehouse operations and inventory control are highly complex and diverse; relying solely on manual memory and data entry is not only time-consuming and labor-intensive but also prone to errors, causing unnecessary losses for businesses. Currently, much warehouse management is based on standardized manual operations and semi-automated computer management, which has the following drawbacks:

[0003] It has few auxiliary devices and limited functionality, making it unsuitable for long-term work.

[0004] The statistical results of cargo data are poor.

[0005] To address these shortcomings, it is essential to design a highly efficient device for acquiring cargo information. Utility Model Content

[0006] To address the aforementioned shortcomings and improve the efficiency of goods identification, this utility model proposes a car-type electronic tag identification device comprising:

[0007] The container, used to hold the goods to be collected, includes two roller shutter doors at the front and back. The roller shutter doors are tightly fitted into the container to shield and isolate wireless signals inside and outside the container when closed.

[0008] Control system, including:

[0009] An input and display device is disposed on one side wall of the enclosure and is used to control the operation of the car-type electronic tag identification device;

[0010] Physical buttons are located on the same side wall as the input and display devices;

[0011] The RFID (Radio Frequency Identification) acquisition module is used to acquire the electronic tags of the goods to be acquired, and then determine whether the goods to be acquired are consistent with the items specified in the scanning task.

[0012] A sensing device is installed near the door frame of the roller shutter door to detect the goods to be collected or the operators.

[0013] In the aforementioned identification device, the housing is fixed to the ground to form a first edge, and anti-collision railings are provided on both the inner and outer sides of the first edge.

[0014] In the aforementioned identification device, the crash barriers include both continuous and discontinuous crash barriers.

[0015] In the aforementioned identification device, the discontinuous crash barriers include corner crash barriers used to protect the corners of the enclosure; the continuous crash barriers include rod-shaped crash barriers used to protect the side walls of the enclosure.

[0016] The aforementioned identification device also includes a shielding plate, which is disposed along the first edge and is used to fill the gap between the box and the ground to isolate wireless signals inside and outside the box.

[0017] In the aforementioned identification device, the physical button also includes an internal door opening / closing button, which is located on the side wall inside the housing and is used to open the roller shutter door from inside the car-type electronic tag identification device.

[0018] In the aforementioned identification device, the sensing device includes one or any combination of a photoelectric sensor, an infrared sensor, and radar.

[0019] The aforementioned identification device also includes an antenna, which is disposed outside the car and is used to communicate with the task sending end to receive at least one scanning task.

[0020] In the aforementioned identification device, the information in the scanning task includes: the task code of the scanning task, the task type, the product information of the product to be collected, the batch information, the production date, and the quantity of products to be collected.

[0021] Compared with existing technologies, this utility model pushes goods into a shielded box and then uses an RFID (Radio Frequency Identification) tag reader to identify the goods entering and leaving the warehouse. This significantly reduces the problems of missing or misreading tags and ensures high speed and accuracy of information collection at core nodes during logistics and transportation.

[0022] When the car-type electronic tag identification device of this application works in conjunction with the warehouse management system, it can overcome the limitations of the traditional barcode management system, realize refined management at the level of individual items, significantly reduce labor costs, and improve work efficiency and circulation efficiency.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0030] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures, and is assumed to be the same definition.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a perspective view of the car-type electronic tag identification device proposed in this utility model. The car-type electronic tag identification device includes a housing 100, a control system, and a sensing device.

[0033] The container 100 is typically a hexahedron with a door on one side, allowing goods to enter or exit through this door. When closed, the container 100 creates a space that shields against external electromagnetic signals. This reduces interference and improves the accuracy of information collection when using RFID to collect information about goods within the container 100. RFID offers advantages such as automated identification and massive data processing, enhancing the efficiency and accuracy of the goods identification process. Compared to traditional contactless sensing technologies like barcodes, RFID tags offer advantages such as contactlessness, fast reading speed, no wear and tear, immunity to environmental influences, long lifespan, ease of use, and anti-collision functionality, enabling the simultaneous identification and processing of multiple tags. However, RFID operates in the radio frequency band and is susceptible to electromagnetic interference, thus requiring a relatively clean electromagnetic environment.

[0034] To achieve better shielding, the door of enclosure 100 can be set as a roller shutter door 9. Figure 2 The diagram shows a front view of the container 100 with the roller shutter door 9 closed. In this state, the goods inside the container 100 are isolated, reducing external wireless signal interference when the RFID data collection program is activated. The status indicator light 8 on the lintel can be used to indicate the opening and closing of the roller shutter door 9, the data collection status inside the container, etc.

[0035] Back Figure 1 The container 100 can generally be fixed to the ground, and the edge of the container 100 in contact with the ground can be called the first edge. To prevent forklifts from colliding with the car-type electronic tag identification device when moving goods, anti-collision barriers 10 can be installed on both the inner and outer sides of the first edge. Specifically, the anti-collision barriers 10 can be continuously installed around the first edge or intermittently installed. For example, long, straight pole-shaped anti-collision barriers can be installed near each side, while the corners of the container 100 are reinforced with corner anti-collision barriers made of thicker and taller materials than the pole-shaped barriers. Furthermore, anti-collision barriers can also be installed inside the container 100 to improve the protective capability of the container 100.

[0036] Figure 3 This is a side view of the car-type electronic tag recognition device of this utility model. The control system of the car-type electronic tag recognition device can be as follows: Figure 3 As shown, these components are centrally located on one side wall of the enclosure 100. The control system mainly includes input and display devices, physical buttons, and an RFID data acquisition module.

[0037] The input and display device, used to assist in inputting commands and displaying product information, alarm prompts, etc., is preferably located on one side wall of the housing 100 and is used to control the operation of the car-type electronic tag identification device. Specifically, it may include a touch screen display 5, or a regular display screen and keyboard and mouse set. The input and display device may also include a speaker 18 for providing audible prompts for errors or alarms.

[0038] Physical buttons can be located on the same side wall as the input and display devices. Specifically, a button control area 6 can be set up near the display screen 5 to centralize frequently used control buttons in one area for easy operation. Figure 4 The diagram shows detailed views of the display screen and physical buttons of the car-type electronic tag identification device of this utility model. As shown, the button control area 6 may include a door curtain reset button 19. When the roller shutter door 9 malfunctions, pressing the reset button 19 returns the roller shutter door 9 to its normal position. The control area 6 may also include an emergency stop switch 20. In case of an emergency, pressing the emergency stop switch 20 cuts off power to the entire car-type electronic tag identification device, thereby terminating dangerous operations. The control area 6 may also include an operation panel power switch 21, used to control whether the display screen 5 is on or off. The control area 6 may also include a door curtain lowering button 22 and a door curtain raising button 23, used to open or close the roller shutter door 9. When the door curtain lowering button 22 or the door curtain raising button 23 is pressed and held, the roller shutter door 9 can be stopped at any position. The control area 6 may also include a host computer debugging port (USB port) 24 and a USB port 25, used to import debugging programs / upgrade the control system or external data. Preferably, roller shutters can be installed on the front and rear walls of the container 100 respectively. When both roller shutters are open simultaneously, the goods to be identified can pass through in one direction, improving passage efficiency. Correspondingly, the control area 6 may also include a hardware single / double door switch 26 for selecting whether the two roller shutters are opened or closed simultaneously or individually.

[0039] Back Figure 3 Physical buttons may also include the power switch 4, which is set in a relatively high position to prevent operators from accidentally touching it while working back and forth, causing an unexpected power outage.

[0040] exist Figure 3The side wall shown may also include inspection ports or other interfaces. For example, it may include a motor and drive chain inspection and maintenance port 1, a WIFI antenna and wired network interface 2, a power supply inspection port 3, and inspection doors 7 for the antenna, host computer, and display screen. The WIFI antenna and wired network interface 2 serves as the interface for data / instruction exchange between the car-type electronic tag identification device and the upper-level management terminal such as the task sending end / warehouse management system. Goods entering and leaving the warehouse bear contactless electronic tags. When goods need to enter or leave the warehouse, the task sending end / warehouse management system transmits a scanning task containing information about the goods to be shipped or received to the control system of the car-type electronic tag identification device via the WIFI antenna and wired network interface 2, which serves as reference data for subsequent readings of the electronic tags inside the car.

[0041] RFID data acquisition module in Figure 3 Not shown in the diagram, its main function is to collect information from the electronic tags of the goods to be collected, and then determine whether the goods to be collected are consistent with the items specified in the scanning task received from the task sender / warehouse management system. If they are consistent, the roller shutter door 9 can be opened to remove the goods and continue to the next task; if they are inconsistent, the specific goods that do not match the scanning task or the missing goods will be displayed on the screen, and the operator will be notified through the speaker 18 at the same time.

[0042] Figure 5 This is a top-view perspective view of the car-type electronic tag identification device of this utility model. Figure 5 The sidewall shown is with Figure 1 On the opposite side of the shown sidewall, a side antenna 27 is installed inside the door on the sidewall, and a back antenna 16 is installed on the rear sidewall of the enclosure. Figure 6 A schematic diagram shows the installation method of the side antenna 27 after the door is opened. The side antenna 27 and the rear antenna 16 are the antennas of the RFID acquisition module. The side antenna 27 and the rear antenna 16 in the figure are just illustrations. In addition to the left and right side walls and the rear side walls, antennas can also be installed on the top wall. The distributed antennas can improve the ability of the car-type electronic tag identification equipment to identify electronic tags, and can collect information from electronic tags from multiple angles, reducing the requirements for goods stacking.

[0043] Figure 5 The image also shows an antenna shield 11, which is used to cover the side antenna 27 and the rear antenna 16, and to protect them to some extent from being hit by goods or forklifts. Figure 5 The document also shows an internal door opening and closing button 12, which is also a physical button located on the side wall inside the housing 100. When personnel are trapped inside the housing 100, the roller shutter door 9 can be opened from the inside. Figure 5The diagram also shows a sensing device installed on the door frame of the roller shutter door 9. This device detects whether the goods to be collected have completely entered or exited the container 100, or whether the operator has left the opening and closing path of the roller shutter door 9, thus serving a safety protection function. The specific sensing device can be one or any combination of two or three of the following: a photoelectric sensor 13, an infrared sensor, and radar. For example, according to the diagram, at least two photoelectric sensors 13 are installed in the lower middle part of the door frame of the roller shutter door 9. Figure 5 The diagram also shows a shielding plate 14, which, as shown, is positioned along the first edge to fill the gap between the housing 100 and the ground, further isolating wireless signals inside and outside the housing and enhancing the electromagnetic shielding effect of the housing 100. The shielding plate 14 is movable; when the car-type electronic tag identification device needs to be moved, the shielding plate 14 is first removed, followed by the removal of part of the protective railing, to facilitate the movement of the housing 100. Furthermore, part of the shielding plate 14 can also be installed on the bottom edge of the roller shutter door 9. In this case, the extension and retraction of the shielding plate 14 can be linked to the opening and closing of the roller shutter door 9. When the roller shutter door 9 opens, the shielding plate 14 retracts / folds back to its storage position on the roller shutter door 9; when the roller shutter door 9 closes, the shielding plate 14 extends synchronously to fill the gap between the roller shutter door 9 and the ground, thereby enhancing the electromagnetic shielding effect. Figure 5 The document also shows a reader / writer maintenance port 15 and a shielded roller shutter door maintenance port 17, both of which are located on the top wall of the housing 100. Mechanical malfunctions can be addressed through these two maintenance ports.

[0044] The following describes the operation procedure of a car-type electronic tag identification device in actual work.

[0045] First, a scanning task can be issued to the car-type electronic tag identification device via an OCOC handheld device. The handheld device receives the scanning task from the warehouse management system and then issues it to the control system via a connection between a Wi-Fi antenna and wired network interface 2. The information in the scanning task includes: the task code, task type, product information of the goods to be collected, batch information, production date, and quantity of goods to be collected. Multiple scanning tasks can be issued simultaneously, but the task type of the same scanning task must be consistent. For example, all scans in the same session should be inbound tasks (or all scans should be outbound tasks; the two should not be confused). After "Association successful" is displayed on display screen 5, display screen 5 continues to publicly display the task product information on the car screen, including the task code, task type, product information, batch information, production date, and quantity of goods to be collected.

[0046] After the cabin-type electronic tag identification device confirms receipt of the scanning task, it clicks the "Read" button on the screen. The shielded roller shutter door 9 automatically closes and begins detecting the electronic tags of the items inside the cabin. It compares the obtained tag content with the information in the issued scanning task. Information such as missing items, extra items, and unrecognizable electronic tags is displayed on screen 5 for the operator to troubleshoot. When a scanning task includes multiple pallets of goods, the next pallet is detected after the previous one is pushed out of the cabin. If no abnormalities are found after all pallets are detected, the scanning task can be submitted. If automatic submission is set, the system will submit the task automatically; otherwise, the "Submit" button must be clicked manually. For multiple scanning tasks, the next scanning task will begin only after the previous one has been submitted.
