An automatic storage and outbound technology device based on RFID and image technology

Abstract

The present invention provides an automatic entry and exit technology device based on RFID and image technology. A conveyor mechanism transports a turnover box loaded with electric meter equipment into an entry and exit channel machine. The electric meter equipment is equipped with an identification code or electronic tag. When the turnover box containing the equipment enters the collection area, the control unit issues a collection instruction. The light-emitting unit on the collection mechanism located above the collection area provides fill light. The collection unit performs image recognition on the identification code on the equipment and collects image information and transmits it to the control unit. On this basis, when the equipment carries an electronic tag, the RFID module reads and writes the electronic tag on the equipment, obtains data, and transmits it to the control unit. By combining image information with RFID data, rapid and accurate data collection and positioning of the equipment in and out of the warehouse are achieved. After identification and collection are completed, the turnover box is transported out of the collection area by the conveyor mechanism, completing an automatic collection operation.

Description

Technical Field

[0001] The present invention relates to the field of warehouse entry and exit technical equipment, and in particular to an automatic warehouse entry and exit technical device based on RFID and image technology. Background Art

[0002] Inbound and outbound lane machines are used to count and locate equipment. To track and identify equipment in real time, the traditional approach is to attach barcodes to the equipment and use the photoelectric interaction between the barcode and the reader to identify the barcode and, therefore, the equipment's information. However, due to the large number of devices entering the warehouse, scanning and identifying each device individually before storing it in the equipment library significantly reduces inventory efficiency.

[0003] The applicant's authorized patent, published under the publication number CN217147260U, describes an in-and-out access channel machine, comprising: a conveyor mechanism, a box scanning device, and an image recognition device. The track includes an image recognition area, the image recognition device positioned above the image recognition area, and is used to identify multiple electricity meters within a turnover box located above the image recognition area. The conveyor mechanism is used to move the turnover box into and out of the image recognition area. The box scanning device is positioned on the conveyor mechanism and is used to scan identification codes on the turnover box. This technical solution combines the image recognition device with the box scanning device, enabling the image recognition device to identify multiple electricity meters within the turnover box, while the box scanning device identifies the turnover box, thereby improving the efficiency of in-and-out access for electricity meters.

[0004] The applicant combined the aforementioned in-and-out channel machine with another authorized patent publication number, CN217739913U, for use with a batch collection mechanism and collection equipment. This new device includes: a fixed plate having multiple camera holes extending through the fixed plate; multiple cameras corresponding to the multiple camera holes; the cameras being positioned on the fixed plate and positioned to one side of the camera holes, and capturing the identification code of the electric meter device in the cargo box through the camera holes; and a base plate positioned on the side of the camera away from the fixed plate and connected to the fixed plate. Unlike the prior art, the above technical solution, through the arrangement of the fixed plate, camera holes, and cameras, enables multiple cameras to identify or scan multiple electric meters or other devices at once. Furthermore, the base plate allows the batch collection mechanism to accommodate other cargo boxes, thereby improving the utilization rate of the batch collection mechanism.

[0005] In actual use, the image recognition device, or acquisition mechanism, in the above-mentioned technical solution was found to have low recognition efficiency. This was because the flashlight in the acquisition mechanism was located next to the camera and shone directly onto the device. This caused partial overexposure on the device surface and uneven overall lighting. This resulted in missing image information when the camera collected it, leading to slow recognition or even failure. Furthermore, the device was unable to collect data from RFID-based electronic tags. Summary of the Invention

[0006] To this end, it is necessary to provide an automatic warehousing and outbound technology device based on RFID and image technology to solve the problem that the fill light source directly illuminates the opposite equipment, causing local overexposure on the surface of the equipment and uneven overall lighting, resulting in missing image information when the camera collects image information, resulting in slow recognition speed or recognition failure, and at the same time, the problem of being unable to realize data collection of RFID-based electronic tags.

[0007] To achieve the above-mentioned objectives, the present invention provides an automatic entry and exit technology device based on RFID and image technology, comprising an entry and exit channel body, a collection mechanism, a transmission mechanism, an RFID module and a control unit; the entry and exit channel body is provided with a collection mechanism, a collection channel for turnover boxes to pass through is provided below the collection mechanism, and the transmission mechanism passes through the bottom of the collection channel; the RFID module is arranged inside the entry and exit channel body, and is used to communicate with the electronic tag on the equipment; the collection mechanism includes a structural plate, a soft light plate, a collection unit, and a light-emitting unit, the structural plate is provided with an opening, the soft light plate is arranged at the opening, and multiple collection units are arranged on the upper surface of the soft light plate, the soft light plate is provided with collection windows at positions corresponding to the multiple collection units, and multiple collection units collect identification code image information through the collection windows, and there are multiple light-emitting units and they are arranged on the upper surface of the soft light plate; the control unit is arranged in the entry and exit channel body, and is electrically connected to the collection unit, light-emitting unit, transmission mechanism and RFID module respectively.

[0008] Furthermore, the light emitting portion of the light emitting unit is arranged to face away from the soft light plate.

[0009] Furthermore, the collection mechanism also includes a circuit board; the collection units are arranged on the lower surface of the circuit board, and the light-emitting units are arranged on the upper surface, and the above structure forms a light-emitting collection module.

[0010] Furthermore, there are multiple light collection modules, and the multiple light collection modules are arranged on the upper surface of the soft light plate.

[0064] See also Figures 1 to 12 This embodiment provides an automatic entry and exit technology device based on RFID and image technology, including an entry and exit channel body 10, a collection mechanism 20, a transmission mechanism 30, an RFID module and a control unit; the entry and exit channel body 10 is a square box, and the shell material is preferably metal.

[0065] A collecting mechanism 20 is disposed within the in-and-out passage body 10. The collecting mechanism 20 is disposed horizontally. A collecting passage 70 for the turnover boxes to pass through is disposed below the collecting mechanism 20. The conveying mechanism 30 passes through the bottom of the collecting passage 70. The conveying mechanism 30 may be composed of a plurality of active rollers and a bracket. The active rollers are rotatably disposed on the bracket. The plurality of active rollers are disposed side by side and connected to a common transmission shaft. The transmission shaft is connected to a drive motor, which is electrically connected to the control unit. The control unit sends instructions to control the drive motor to drive the transmission shaft to drive the active rollers to rotate, causing the turnover boxes to enter the collecting passage 70. When the turnover box reaches the collecting area, the conveying stops, waits for the collection work to be completed, and then resumes the conveying, causing the turnover box to leave the collecting passage 70.

[0066] The RFID module is installed inside the access channel body 10 and is used to communicate with the electronic tags on the devices. The RFID module includes a read / write unit and a software unit. The read / write unit reads and writes the electronic tags or radio frequency cards on the devices via wireless radio frequency, transmits the read / write information to the software unit, and the software unit processes the read / write information accordingly, thereby achieving the purpose of accurately identifying and locating each device carrying the electronic tag or radio frequency card.

[0067] The collection mechanism 20 includes a structural plate 201, a soft light plate 202, a collection unit 203, and a light-emitting unit 204. The structural plate 201 is provided with an opening, and the structural plate 201 is preferably made of an opaque metal material. The soft light plate 202 is provided at the opening, and the opening is adapted to the soft light plate 202. The soft light plate 202 is fixed at the opening. The size of the opening can be slightly smaller than the soft light plate 202. The fixing method can be to provide multiple through holes in the area of ​​the soft light plate 202 that is larger than the opening, and to provide multiple protrusions at corresponding positions on the structural plate 201. The multiple through holes are respectively inserted into the multiple protrusions so that the soft light plate 202 does not deviate in the horizontal direction. The top of the protrusion can be provided with an external thread or an internal thread, and the vertical fixation is achieved by connecting the threaded cap with the protrusion thread. The soft light panel 202 is a panel that softens strong light. Its principle is to convert the light from the light emitting unit 204 into soft diffused light through the soft light panel 202, and make the light uniform after multiple reflections, or when the light passes through, a small amount of light passes through to make the light soft. Its material can be translucent plastic or glass with a softening coating on the surface. Preferably, acrylic material can be used, especially white acrylic. Unlike the prior art that sets a fill light next to the camera to directly illuminate the device scanning code, the light emitting unit 204 is set on the upper side of the soft light panel 202. Preferably, the light emitting part of the light emitting unit 204 is set to face away from the soft light panel 202. The light emitted by the light emitting unit 204 is softened by the soft light panel 202 and then reaches the device scanning code, so that the illumination of the recognition area is uniform, and no local area is overexposed, resulting in recognition failure. The light emitting unit 204 may be a plurality of LED light strips, and the plurality of light strips are arranged on the same-distance dividing line of the soft light plate 202 so that the overall light emission is more uniform.

[0068] Multiple acquisition units 203 are arranged on the upper surface of the soft light plate 202. The soft light plate 202 has acquisition windows at positions corresponding to the multiple acquisition units 203. The size of the acquisition window is adapted to the acquisition unit 203 to avoid leaving light-transmissive gaps that affect the acquisition function of the acquisition unit 203. Multiple acquisition units 203 collect identification code image information through the acquisition window. There are multiple light-emitting units 204 and they are arranged on the upper surface of the soft light plate 202. The acquisition unit 203 can be a camera with an image acquisition function.

[0069] The control unit is arranged in the in-and-out channel body 10, and the control unit includes a circuit board 205 and a microcontroller (CPU). The control unit can be connected to the host computer for communication. The communication connection method can be a wired, Bluetooth or WiFi connection. The host computer sends instructions to the control unit, and the control unit performs identification and collection after receiving the instructions. After the identification and collection are completed, the result information is transmitted back to the host computer for overall management by the host computer. The control unit is electrically connected to the collection unit 203, the light-emitting unit 204, the transmission mechanism 30 and the RFID module respectively.

[0070] The present invention uses a conveying mechanism 30 to convey a turnover box loaded with electric meter equipment into an entry and exit channel machine. The electric meter equipment is equipped with an identification code or an electronic tag. When the turnover box with the equipment inside enters the collection area, the control unit issues a collection instruction. The light-emitting unit 204 on the collection mechanism 20 above the collection area is supplemented with light through a soft light plate. The collection unit 203 performs image recognition on the identification code on the equipment and collects image information and transmits it to the control unit. On this basis, when the equipment carries an electronic tag, the RFID module reads and writes the electronic tag on the equipment, obtains data and transmits it to the control unit. The combination of image information and RFID data realizes fast and accurate data collection and positioning of the equipment in and out of the warehouse. After the identification and collection are completed, the turnover box is conveyed out of the collection area through the conveying mechanism 30 to complete an automatic collection work.

[0071] In some embodiments, the collection mechanism 20 further includes a circuit board 205; the collection units 203 are arranged on the lower surface of the circuit board 205, and the light-emitting units 204 are arranged on the upper surface. The above structure forms a light-emitting collection module. There are multiple light-emitting collection modules, and multiple light-emitting collection modules are arranged on the upper surface of the soft light plate 202. Through the above structure, the fill light of the light-emitting unit 204 is more uniform, and the internal structure is simple and efficient, which is convenient for production and assembly. Preferably, the light-emitting unit 204 is an LED lamp, which is energy-saving and environmentally friendly and has a long service life. Preferably, the collection unit 203 is a wide-angle camera, which can reduce the number of the collection units 203 to reduce costs, or achieve excessive coverage of the collection area without reducing the number of the collection units 203, thereby improving the collection success rate.

[0072] In some embodiments, a door opening / closing mechanism 40 is further included. The door opening / closing mechanism 40 is disposed at the entrance of the collection channel 70 and is electrically connected to the control unit. The door opening / closing mechanism 40 is a movable sunshade that can be single-open or double-open. The control unit controls the door opening / closing mechanism 40 to close before collection begins, thereby protecting the interior of the collection area from external interference. This can also prevent the influence of external light and improve the success rate of collection and recognition. After collection is completed, the conveying mechanism 30 operates to convey the turnover box out of the collection area. Preferably, the door opening / closing mechanism 40 is a rolling door or an electric sliding door, as long as it can be opened and closed. A rolling door is preferred, as it saves internal space of the device and has a simpler and more practical structure.

[0073] The specific process can be as follows Figure 9 As shown, the turnover box is first placed on the conveyor belt of the in-and-out channel machine, and then the turnover box is transferred to the designated position through the conveyor belt, that is, the position directly below the collection mechanism 20, and then the rolling door is lowered to the designated position, and the RFID starts scanning. After the scanning is completed, the rolling door returns to the origin.

[0074] In some embodiments, a box scanning unit 50 is further provided within the access channel body 10 and is electrically connected to the control unit. The box scanning unit 50 may be a camera or a sensor that is used to identify the entry of a turnover box and its arrival in the collection area, enabling more efficient entry and collection operations. Furthermore, the unit can also identify the height of the turnover box.

[0075] In some embodiments, a lifting mechanism 60 is further included. The lifting mechanism 60 is disposed at the top of the collection channel 70 within the access channel body 10. The lifting mechanism 60 is located above the collection mechanism 20 and is connected to the collection mechanism 20. The lifting end of the lifting mechanism 60 is located at the bottom, and the distal end of the lifting end is connected to the top of the collection mechanism 20. The lifting mechanism 60 drives the collection mechanism 20 upward and downward. Based on the function of the box scanning unit 50 in the previous embodiment to identify the height of the turnover box, when the turnover box is insufficiently high and the distance from the collection mechanism 20 is too large, the lifting mechanism 60 can lower the collection mechanism 20 to the appropriate distance to complete the collection process. Furthermore, when the next turnover box enters, the box scanning unit 50 performs a real-time scan to confirm the height, and the control unit controls the lifting mechanism 60 to maintain the original height or to raise or lower it. Preferably, there are two box scanning units 50, which are respectively arranged on the same side or different sides of the entrance and exit of the collection channel 70, so as to facilitate real-time confirmation of the entry and exit of the turnover box and realize collection work in any transmission direction.

[0076] The flow chart of the above embodiment is as follows: Figure 10 As shown, a turnover box is first placed on the conveyor belt of the in-and-out access machine. The conveyor belt then transports the turnover box to a designated location, directly below the collection mechanism 20. The collection platform then descends to a designated position, within a preset distance from the turnover box. This distance is measured using a distance sensor. Simultaneously, a rolling door can also be lowered to a designated position. The collection platform then begins scanning the code. After scanning is complete, the scanned data is reported. The collection platform then returns to its origin. The conveyor belt then transports the turnover box to the warehouse.

[0077] The automatic warehousing and outbound technology device based on RFID and image technology can be used in conjunction with intelligent flexible identification storage shelves. The equipment collected by the automatic warehousing and outbound technology device based on RFID and image technology and entered into the system storage database can be transferred to the shelf through a transfer robot or a transmission channel machine. The equipment is then collected and identified through the collection layer in the intelligent flexible identification storage shelf and the warehousing and outbound information is checked to achieve full-process monitoring of the equipment's entry and exit and storage location.

[0078] The specific process is as follows Figure 11 As shown in the figure, the access control system is installed in a room with access control. First, the user logs in to the access control system. After successful login, the warehouse management system enters access mode. Then, an asset, such as an electricity meter, is placed in a storage location. The barcode collection mechanism of the access control system is activated to capture the barcode. Upon receiving the barcode, the warehouse management system determines whether it is on an undelivered work order or a pre-delivered inventory list. If not, a prompt is issued to remove the illegal asset, and the alarm device in the equipment control system is activated to sound an alarm. If so, the system further determines whether there is any undelivered power supply. If so, a work order is entered; otherwise, the power supply is returned to storage. Finally, the inventory list is reported to the marketing system, which generates statistical reports.

[0079] The present invention can be located within a storage shelf at the asset entry point. In certain embodiments having a storage shelf, the storage shelf includes a shelf body 80 and a collection layer 90; the collection layer 90 is provided in plurality, and the plurality of collection layers 90 are horizontally disposed within the shelf body 80 and arranged vertically, with space for accommodating turnover boxes 100 being provided between adjacent two collection layers 90.

[0080] The collection layer plate 90 is similar to the above-mentioned collection mechanism 20. It includes a load-bearing top plate 901, a bottom plate 902 (the load-bearing top plate 901 and the bottom plate 902 are equivalent to the structural plate 201), a layer identification unit 903 (equivalent to the collection unit 203), a layer light-emitting unit 904 (equivalent to the light-emitting unit 204) and a layer soft light plate 905 (equivalent to the soft light plate 202); the top surface of the load-bearing top plate 901 is used to carry the turnover box 100, and the bottom plate 902 is connected to the bottom surface of the load-bearing top plate 901. The combination of the two forms a hollow closed structure. The load-bearing top plate 901 and the bottom plate 902 can preferably use an opaque metal material, such as stainless steel or iron, and the two can be integrally formed or detachably connected. It should be noted that the closed structure is not completely airtight, it only needs to prevent light from leaking. The bottom plate 902 is provided with an opening adapted to the layer soft light plate 905, and the layer soft light plate 905 is fixed at the opening. The size of the opening can be slightly smaller than the layer soft light plate 905. The fixing method can be to set multiple through holes in the area of ​​the layer soft light plate 905 that is larger than the opening, and set multiple protrusions at the corresponding positions of the bottom plate 902, and respectively insert the multiple through holes into the multiple protrusions so that the layer soft light plate 905 does not shift in the horizontal direction, and external or internal threads can be set at the top of the protrusions, and vertical fixation can be achieved by threaded caps. Multiple layer identification units 903 and multiple layer light-emitting units 904 are all arranged inside the closed structure. Preferably, multiple layer identification units 903 and multiple layer light-emitting units 904 are all fixed on the layer soft light plate 905. The shelf soft plate 905 is provided with a plurality of windows for the shelf identification unit 903 to scan the device identification code below. The size of the windows is adapted to the size of the shelf identification unit 903 to avoid leaving light-transmitting gaps that would affect the recognition function of the shelf identification unit 903. The shelf identification units 903 are arranged in an array, three columns and four rows. The number of shelf identification units 903 can also be increased or decreased according to the size of the recognition area, as long as full coverage of the recognition area is achieved.

[0081] The layer identification unit 903 can be a camera, preferably a wide-angle camera, which can reduce the number of the layer identification units 903 to reduce costs, or achieve excessive coverage of the identification area without reducing the number of the layer identification units 903 to improve the recognition success rate.

[0082] The layer light emitting unit 904 may be a plurality of LED light strips, and the plurality of light strips are arranged on the same-distance dividing lines of the layer soft light plate 905, so that the overall light emission is more uniform.

[0083] It also includes a control unit 110, which is connected to the shelf identification unit 903 and the shelf light-emitting unit 904 respectively. The control unit 110 includes a shelf circuit board 1101 and a microcontroller 1102 (CPU). The control unit 110 can be configured separately for each collection shelf 90, or multiple collection shelves 90 can share one control unit 110. The control unit 110 can be set on the top of the shelf body 80 or inside one of the collection shelves 90. The control unit 110 can be connected to the mains electricity to power the shelf identification unit 903 and the shelf light-emitting unit 904. The control unit 110 can be connected to the host computer for communication. The communication connection method can be a wired, Bluetooth or WiFi connection. The host computer sends instructions to the control unit 110, and the control unit 110 performs identification and collection work after receiving the instructions. After the identification and collection is completed, the result information is transmitted back to the host computer for overall management by the host computer.

[0084] When using this embodiment, it is only necessary to push the turnover box 100 containing the equipment into the intelligent flexible identification storage shelf. The collection layer 90 located above the equipment box can automatically illuminate and identify the identification area of ​​the turnover box 100 according to preset instructions. The identification information is stored and uploaded through the control unit 110. Through the above process, the position of a certain device can be located at any time. Combined with an automatic manipulator or a transfer robot, the directional intelligent identification, storage and retrieval of the equipment in the turnover box 100 can be realized.

[0085] The specific process is as follows Figure 12 As shown, a turnover box is stored in the storage space between the collection layers of the intelligent flexible identification storage shelf. When the turnover box is in place, the formation switch at the bottom of the storage space senses that the turnover box is in place, and then the collection layer is started to scan. After scanning, the scanning data is reported, which can be specifically reported to the warehouse management system, realizing data collection on the shelf.

[0086] This embodiment realizes the recognition, collection and storage of device barcodes through the shelf body 80, the control unit 110 and the shelf identification unit 903 and the shelf light-emitting unit 904 of the collection shelf 90. By setting the shelf soft light plate 905, the light received in the recognition area is made soft and uniform, thereby improving the recognition success rate of the shelf identification unit 903 and effectively improving the collection efficiency.

[0087] In actual use, although the light can be softened after passing through the layer soft light plate 905, due to the limited space in the collection layer 90, the distance between the light-emitting part of the layer light-emitting unit 904 and the layer soft light plate 905 is very small, and there is actually a problem of higher brightness in local areas. Therefore, in order to further optimize and make the lighting more uniform, the light-emitting part of the layer light-emitting unit 904 is set back to the layer soft light plate 905, that is, the light-emitting part is facing the bottom surface of the supporting plate, and the light is directly irradiated on the bottom surface of the supporting top plate 901, and is refracted back to the layer soft light plate 905. After being softened by the layer soft light plate 905, a more uniform and soft fill light is achieved, further improving the recognition success rate.

[0088] In certain embodiments of the intelligent flexible identification storage rack, the distance between the shelf identification unit 903 and the device identification code is 7-15 cm. By optimizing the fill light effect, the present invention can achieve recognition of device identification codes at greater distances. That is, the height between the layers of the shelf body 80 can be increased to accommodate turnover boxes 100 of different heights or devices placed in turnover boxes 100 at different orientations. Essentially, this is to accommodate different distances between the device identification code and the shelf identification unit 903. In other words, a single shelf can be used to store and identify turnover boxes 100 of different heights and devices of different specifications, with high economic applicability.

[0089] In certain embodiments of the intelligent flexible identification storage rack, an online interface 120 is further included, and the online interface 120 is provided on one side or both sides or the back or the top of the rack body 80, and the control units 110 of multiple racks are connected through the online interface 120 to achieve online connection. It should be noted that the control units 110 of multiple racks can be connected via data connection lines. Preferably, the online interface 120 is provided on both sides of the rack body 80, so as to facilitate online connection when multiple intelligent flexible identification storage racks are arranged side by side, and the connection lines are not exposed. Specifically, a main control device is also included, and the main control device is provided in the rack body 80 and connected to the control unit 110. The top of the rack can be a space for accommodating the main control device. The main control device can include a microcomputer, an information storage unit and a networking unit to realize real-time acquisition of the equipment using the shelf identification unit 903.

[0090] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the present invention's description and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of protection of the present invention's patent.
