Description

Technical Field

[0001] This invention relates to the field of display cabinet lighting control technology, and in particular to an RFID lighting adaptive control system with RFID scene recognition, automatic matching of lighting parameters, dynamic lighting effect switching and trendy toy traceability functions. Background Technology

[0002] Trendy toy display cases create different display atmospheres through interchangeable scene backdrops, and are further enhanced by lighting to improve the display effect. Existing lighting solutions for these display cases mainly suffer from the following problems: (1) The scene background can be replaced but the lighting cannot be linked: The existing display cabinets with replaceable scene backgrounds still maintain the original color temperature and brightness of the lighting after the background is replaced. Mismatches such as snow scene with warm yellow light and ancient style scene with cool white light are common, and the scene atmosphere and lighting atmosphere cannot be automatically matched. (2) Lighting adjustment relies on manual operation: The existing display cabinets' lighting modes are mostly switched by mechanical buttons. After each scene change, the color temperature, brightness, and dynamic mode of each cabinet need to be manually adjusted, which is cumbersome when multiple cabinets are combined for display. (3) Intelligent dimming depends on APP and network: Some intelligent display lights achieve dimming by connecting to a mobile APP via Bluetooth or Wi-Fi, which depends on external devices and network environment. This has a high threshold for non-technical users, and the dimming function will fail when the network is disconnected or the APP stops maintenance. (4) Material recognition dimming path is costly and unstable: There is a scheme based on near-infrared spectral sensor to identify the material of the item and match the control parameters. This scheme requires spectral sensor and recognition algorithm, which is costly. Moreover, the coating materials of trendy toys are diverse and the surface reflection is different. The spectral recognition is not stable enough and it is difficult to implement it at low cost in consumer-grade trendy toy display cabinets. (5) High-end trendy toys lack authenticity and traceability methods: the second-hand trading of limited edition trendy toys is subject to the risk of counterfeit products, and the existing display cabinets do not have the ability to record the identity of trendy toys, verify authenticity, and maintain and trace their origin; (6) Lighting parameters have no scene memory capability: The existing display cabinets require the lighting to be readjusted every time the scene is changed, and do not have the ability to automatically memorize and restore the lighting parameters according to the scene.

[0003] Furthermore, US Patent 8248214 discloses a scheme for adjusting display lighting using RFID technology. This scheme attaches RFID tags to the product itself, reads the product identifier using a sensor, and then looks up the corresponding table to adjust the color temperature and brightness of the variable-color light source. However, this scheme uses RFID tags attached to the product itself, identifying the product rather than the display scene. It does not disclose a structure for attaching RFID tags to a replaceable scene backdrop and triggering scene recognition through backdrop installation, nor does it address the automatic switching of ambient lighting as the backdrop is changed.

[0004] Therefore, there is a need for an RFID-based adaptive lighting control system that combines automatic scene recognition and automatic lighting matching, is available offline, is low-cost, and has the ability to trace the origins of trendy toys. Summary of the Invention

[0005] The purpose of this invention is to provide an RFID-based adaptive lighting control system to solve the technical problems of existing display cabinet scene back panels and lighting not being linked, lighting adjustment relying on manual operation, intelligent dimming relying on APP and network, material identification dimming being costly and unstable, high-end trendy toys lacking authenticity traceability, and lighting parameters lacking scene memory capability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An RFID-based adaptive lighting control system includes a display cabinet, a scene backdrop, an RFID reader / writer, a lighting module, and a control unit.

[0007] The display cabinet has a display space and a back panel mounting position.

[0008] The scene back panel is detachably installed at the back panel mounting position. The scene back panel is equipped with an RFID tag, which stores scene identification information.

[0009] The RFID reader is installed in the display cabinet and corresponds to the position of the back panel mounting position, and is used to read the RFID tag on the scene back panel installed at the back panel mounting position.

[0010] The lighting module is installed in the display cabinet and emits light towards the display space.

[0011] The control unit is electrically connected to the RFID reader and the lighting module respectively. The control unit stores a mapping table between scene identifiers and lighting parameters. The lighting parameters include color temperature parameters, brightness parameters, and dynamic mode parameters. The control unit obtains the scene identifier information read by the RFID reader, queries the mapping table to obtain the corresponding lighting parameters, and drives the lighting module to emit light according to the corresponding lighting parameters.

[0012] Preferably, the RFID tag is a passive high-frequency tag, embedded inside the back panel of the scene, and the operating frequency of the RFID tag is 13.56MHz.

[0013] Preferably, the back panel mounting position is a slot located on the back of the display cabinet, the antenna of the RFID reader is located at the bottom of the slot, and when the scene back panel is inserted into the slot, the distance between the RFID tag and the antenna of the RFID reader is no more than 10mm.

[0014] Preferably, the color temperature parameter ranges from 2700K to 6500K, the brightness parameter ranges from 0 to 100%, and the dynamic mode parameter includes four modes: constant brightness, breathing, follow light, and gradient.

[0015] Preferably, the lighting module includes an LED light strip and a driving circuit. The LED light strip includes warm color temperature LEDs and cool color temperature LEDs. The driving circuit adjusts the color temperature by adjusting the mixing ratio of the warm color temperature LEDs and the cool color temperature LEDs, and adjusts the brightness by pulse width modulation.

[0016] Preferably, when the RFID reader fails to read the RFID tag, or when the read scene identification information is not recorded in the mapping table, the control unit drives the lighting module to emit light according to the default lighting parameters.

[0017] Preferably, it also includes a mode button, which is disposed in the display cabinet and electrically connected to the control unit; when the mode button is triggered, the control unit switches the lighting parameters in a preset order and overwrites the lighting parameters matched by the mapping table; when the mode button is pressed and held for a preset time, the control unit resumes illuminating according to the lighting parameters matched by the mapping table.

[0018] Preferably, the RFID tag also stores a trendy toy identification mark, which includes a unique identification code and a authenticity verification code. The control unit reads the trendy toy identification mark and verifies its authenticity.

[0019] Preferably, it also includes a display unit, which is disposed in the display cabinet and electrically connected to the control unit, and the display unit displays the verification result and traceability information of the trendy toy identity mark.

[0020] Preferably, the RFID tag has a readable and writable storage area, which stores maintenance records and transfer records, and the RFID reader writes maintenance records into the readable and writable storage area.

[0021] Preferably, the number of scene back panels is at least two, and the at least two scene back panels are installed side by side in the back panel mounting position. The number of RFID readers corresponds to the number of scene back panels. The control unit obtains the scene identification information of each scene back panel, determines the target scene identification according to the preset master-slave priority, and drives the lighting module to emit light according to the lighting parameters corresponding to the target scene identification.

[0022] Preferably, it also includes a power module to supply power to the RFID reader, the lighting module and the control unit, the power module including a USB power interface and a rechargeable battery.

[0023] This invention also provides an RFID lighting adaptive control method, employing the aforementioned RFID lighting adaptive control system, comprising the following steps: an RFID reader detects the scene backplate at the backplate mounting position and reads the scene identification information stored in the RFID tag; a control unit queries a mapping table based on the scene identification information to obtain the corresponding color temperature parameters, brightness parameters, and dynamic mode parameters; the control unit drives the lighting module to emit light according to the corresponding lighting parameters; when the RFID reader detects a change in the scene backplate, it rereads the replaced RFID tag, and the control unit rematches the lighting parameters according to the replaced scene identification information, driving the lighting module to automatically switch.

[0024] Compared with the prior art, the beneficial effects of the present invention include: 1. The RFID tags on the scene backplate store scene identification information. When the backplate is installed, the RFID reader automatically reads the information and the control unit queries the mapping table to match the lighting parameters. When the backplate is replaced, the color temperature, brightness and dynamic mode of the lights are automatically switched. The scene atmosphere and the lighting atmosphere are automatically matched without any manual adjustment. 2. The matching of lighting parameters is completed locally by the control unit. The lighting switches automatically after the scene changes. When multiple cabinets are combined for display, there is no need to operate each cabinet individually, eliminating the tediousness of manual cyclic switching. 3. Recognition and dimming are all completed offline locally in the display cabinet, without relying on mobile APP, Bluetooth or network environment, with no threshold for use, and no risk of function failure due to network outage or APP maintenance. 4. The technology of using RFID tags to identify scene markings, compared with the near-infrared spectral material identification method, does not require spectral sensors and identification algorithms. The cost of a single passive RFID tag is only 0.3 yuan. The identification is not affected by the coating material and reflectivity of the trendy toys. It is stable and reliable and can be implemented at low cost in consumer-grade trendy toy display cabinets. 5. The RFID tag simultaneously stores the trendy toy's identity identifier, and the control unit verifies the authenticity verification code and displays the verification result and traceability information through the display unit, providing a hardware carrier for the authenticity identification and circulation traceability of limited edition trendy toys; the same RFID tag simultaneously carries scene identification and trendy toy identity identifier, and the RFID reader can complete the matching of light parameters and authenticity verification at the same time by reading once, realizing one tag for two purposes, without the need to set up two sets of identification hardware; 6. The mapping table stores the correspondence between scene identifiers and lighting parameters. When the scene backplate is inserted again, the matching lighting parameters are automatically restored, and it has the ability to memorize lighting parameters according to the scene. 7. The three technical features of this invention—RFID tag scene recognition, alignment reading between the reader and the backplate mounting position, and lookup table driving—create a synergistic effect: the tag imbues the scene with its own identity, alignment reading makes the backplate insertion action itself a recognition trigger, and lookup table driving allows the recognition result to be directly mapped into lighting control quantities. These three elements work together to achieve fully automatic scene-light linkage—"changing the backplate changes the lighting"—rather than a simple combination of recognition, triggering, and driving. Compared to solutions that embed RFID tags in the product itself, this invention uses a replaceable scene backplate as a carrier. The scene identity moves with the backplate, recognition occurs with insertion, and lighting changes with the scene—a scene-level linkage that cannot be achieved with product tags combined with area sensors.

[0027] To facilitate understanding of the technical solution of the present invention, a detailed description is provided below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1: Overall Structure Please see Figures 1 to 3 This embodiment provides an RFID lighting adaptive control system, including a display cabinet 100, a scene back panel 200, an RFID reader / writer 300, a lighting module 400, and a control unit 500.

[0029] The display cabinet 100 is a rectangular cabinet with an external dimension of 400mm wide, 300mm deep and 500mm high, forming an internal display space 120. The back of the display cabinet 100 is provided with a back panel mounting position 110, which is a slot 111 extending horizontally. The slot 111 has a groove width of 4mm and a depth of 20mm.

[0030] The scene back panel 200 has a 3mm thick acrylic printed back panel 210, which is detachably inserted into the slot 111. An RFID tag 220 is embedded in the lower edge of the panel 210. The RFID tag 220 is a passive high-frequency tag (NTAG213) with a working frequency of 13.56MHz, a storage capacity of 144 bytes, and a cost of 0.3 yuan per tag. The RFID tag 220 stores scene identification information.

[0031] The RFID reader 300 is located on the back of the display cabinet 100. The antenna of the RFID reader 300 is located at the bottom of the slot 111. When the scene back panel 200 is inserted into the slot 111, the distance between the RFID tag 220 and the antenna of the RFID reader 300 is 8mm and no more than 10mm, which is within the stable reading range.

[0032] The lighting module 400 includes an LED light strip 410 and a driving circuit 420. The LED light strip 410 is located on the top inner side of the display cabinet 100 and emits light towards the display space 120.

[0033] The control unit 500 is a microcontroller-based control board (microcontroller model STM32F030), which is electrically connected to the RFID reader / writer 300 and the driving circuit 420 of the lighting module 400 respectively. The memory of the control unit 500 stores a mapping table 510 between scene identifiers and lighting parameters.

[0034] The power module 600 supplies power to the RFID reader 300, the lighting module 400 and the control unit 500. The power module 600 includes a USB power interface (5V / 2A) and a rechargeable lithium battery (3.7V / 2000mAh). When the external power supply is disconnected, the lithium battery provides power.

[0035] Example 2: Mapping Table and Lighting Parameters Please see Figure 4Mapping table 510 stores the correspondence between scene identifiers and lighting parameters, including color temperature, brightness, and dynamic mode parameters. The color temperature range is 2700K to 6500K, the brightness range is 0 to 100%, and the dynamic mode parameters include four modes: constant, breathing, follow, and gradient. Example entries in mapping table 510 include: scene identifier "SNOW01" corresponding to a color temperature of 6000K, brightness of 90%, and constant mode, used for snow scenes; scene identifier "YARD02" corresponding to a color temperature of 3000K, brightness of 70%, and breathing mode, used for ancient courtyard scenes; and scene identifier "CYBR03" corresponding to a color temperature of 4500K, brightness of 85%, and gradient mode, used for cyberpunk street scenes. Mapping table 510 supports any combination of color temperature parameters, brightness parameters, and dynamic mode parameters within their respective value ranges. When a user creates a custom scene backplate 200, the user can write the custom scene identifier and corresponding lighting parameters into mapping table 510 through connection to a host computer or by combining operations with mode button 520, thereby realizing the lighting configuration of the user-customized scene.

[0036] Please see Figure 7 The LED light strip 410 includes alternating warm color temperature LED beads 411 (color temperature 2700K) and cool color temperature LED beads 412 (color temperature 6500K). The driving circuit 420 achieves color temperature adjustment in the range of 2700K to 6500K by adjusting the mixing ratio of warm color temperature LED beads 411 and cool color temperature LED beads 412, and achieves brightness adjustment in the range of 0 to 100% by pulse width modulation (PWM).

[0037] Example 3: Adaptive Lighting Control Method Please see Figure 5 This embodiment provides an RFID light adaptive control method, using the system of Embodiment 1, and includes the following steps: S1. The RFID reader 300 polls the slot 111 twice per second to detect whether the scene backplate 200 is inserted. When the scene backplate 200 is detected to be inserted, the reader reads the scene identification information stored in the RFID tag 220. The reading time is no more than 200ms.

[0038] S2, the control unit 500 queries the mapping table 510 based on the scene identification information to obtain the corresponding color temperature parameters, brightness parameters and dynamic mode parameters.

[0039] S3, the control unit 500 drives the lighting module 400 to emit light according to the corresponding lighting parameters; the light switching process adopts a 2-second gradual transition to avoid visual discomfort caused by sudden changes in brightness and color temperature.

[0040] S4. When the RFID reader 300 detects that the scene backplate 200 has been removed or replaced, it rereads the replaced RFID tag 220. The control unit 500 rematches the lighting parameters according to the replaced scene identification information, driving the lighting module 400 to switch automatically. The specific logic of the replacement detection is as follows: the RFID reader 300 polls at a frequency of 2 times per second. First, it detects that the RFID tag 220 has left the scene (scene backplate 200 has been removed), and then it detects that the new RFID tag 220 has entered the scene (scene backplate 200 has been inserted). The control unit 500 compares the scene identification read this time with the scene identification recorded last time. If the identification has changed, it is determined that the scene backplate 200 has been replaced, triggering rematching. The user's action of replacing the scene backplate 200 itself completes the scene switching of the lighting, without the need for button or APP operation.

[0041] Example 4: Manual Override vs. Default Strategy This embodiment, based on Embodiment 1, further includes a mode button 520. The mode button 520 is located on the top outer wall of the display cabinet 100 and is electrically connected to the control unit 500. When the mode button 520 is briefly pressed, the control unit 500 switches the dynamic mode in a preset sequence of "constant light → breathing → follow light → gradient" and simultaneously fine-tunes the color temperature level, covering the lighting parameters matched by the mapping table 510 to meet the user's temporary adjustment needs. When the mode button 520 is pressed for 3 seconds, the control unit 500 resumes illuminating according to the lighting parameters matched by the mapping table 510.

[0042] When the RFID reader 300 fails to read the RFID tag 220 (e.g., it is not inserted into the scene backplate 200 or the backplate is not configured with a tag), or when the read scene identification information is not recorded in the mapping table 510 (user-made backplate), the control unit 500 drives the lighting module 400 to emit light according to the default lighting parameters, which are color temperature 4000K, brightness 80%, and constant light mode.

[0043] Example 5: Tracing the Origin of Trendy Toys Please see Figure 6 This embodiment, based on Embodiment 1, further specifies that the RFID tag 220 also stores a trendy toy identification mark, which includes a unique identifier (UID) and a authenticity verification code. The authenticity verification code is generated by the manufacturer by encrypting the unique identifier according to a preset algorithm. After reading the trendy toy identification mark, the control unit 500 verifies the authenticity verification code using the same algorithm. The front frame of the display cabinet 100 is equipped with a display unit 530, which is a 0.96-inch OLED display screen electrically connected to the control unit 500, displaying the verification result (genuine / failed) and traceability information (trendy toy name, limited edition number, and manufacturing date).

[0044] The RFID tag 220's readable and writable storage area also stores maintenance records and circulation records. After each cleaning and maintenance of the toy, the control unit 500 writes the maintenance date into the readable and writable storage area through the RFID reader 300, and the display unit 530 simultaneously displays the most recent maintenance date. When the toy is circulated, the new owner adds circulation records through the system's write operation, forming a traceable circulation chain.

[0045] Example 6: Multi-backplate combination This embodiment, based on Embodiment 1, further limits the number of scene back panels 200 to two. The two scene back panels 200 are inserted side-by-side into slots 111 of the widened display cabinet. There are two RFID readers 300, corresponding to the positions of the RFID tags 220 on the two scene back panels 200 respectively. Slots 111 are numbered by position: the left position is numbered 1, and the right position is numbered 2. The control unit 500 presets a master-slave priority according to the position number, with the position number being the master back panel mounting position. The control unit 500 acquires the scene identification information of the two scene back panels 200, determines the scene identification on the scene back panel 200 at the master back panel mounting position as the target scene identification, and drives the lighting module 400 to emit light according to the lighting parameters corresponding to the target scene identification. The scene identification on the slave back panel mounting position does not affect the lighting parameters and is only used as an extended scene record. Since the antenna of the RFID reader 300 is fixed in position while the RFID tag 220 moves with the scene back panel 200, after the user swaps the positions of the two scene back panels 200, the scene identifier on the main back panel mounting position changes accordingly. The control unit 500 re-determines the target scene identifier according to the new reading result, and the lighting automatically switches to the lighting parameters of the new main back panel scene, providing a flexible lighting strategy for multi-scene combination display.

[0046] Those skilled in the art should understand that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit its scope of protection.
