Description

Technical Field

[0001] This invention relates to the field of intelligent terminal equipment and surface treatment technology, and in particular to an intelligent ordering board with a nano-coating and a remote update system. Background Technology

[0002] Smart ordering displays are widely used in catering establishments. For public health reasons, some devices have antibacterial nano-coatings applied to the screen surface. However, under long-term, high-frequency touching and cleaning, such coatings generally suffer from poor adhesion, easy wear, and irreversible consumption of antibacterial substances, leading to rapid functional failure. Frequent screen replacements or professional recoating are costly, affecting the device's lifespan and commercial reliability. Currently, there is a lack of a comprehensive solution that can effectively combine strong adhesion with self-maintenance functionality.

[0003] Chinese Patent Publication Number: CN118897634B discloses a touchscreen with an anti-glare, anti-fingerprint, and antibacterial nano-coating, relating to the field of touchscreen technology. The touchscreen includes a touchscreen, a connecting cable, and a connector. The connecting cable and connector are mated together. The touchscreen also includes a multi-functional component and an auxiliary signal stabilizing component. The multi-functional component is located below the auxiliary signal stabilizing component. The multi-functional component includes an A contact block and a B contact block fixedly connected for feedback from different code programs. The multi-functional component also includes a trapezoidal block. The auxiliary signal stabilizing component includes a moving part. A pressing spring is provided on the upper part of a square rod, allowing manual operation of the square rod to move laterally with the assistance of a guide post. The sliding in the channel allows for the switching of control device codes. At the same time, this lateral movement allows the touch point to wipe the touch screen surface through a drive rod that is indirectly connected to it, carrying a wiping body. It can be seen that the touch screen with anti-glare, anti-fingerprint, and antibacterial nano-coating has the following problems: (1) It relies on the one-time slow release of the premixed antibacterial agent in the coating; the function is irreversibly reduced as the effective ingredients are consumed and worn, and usually needs to be replaced or recoated every few months; (2) As a static functional film, it does not have sensing and data processing capabilities; it cannot sense its own wear status, and maintenance depends entirely on manual periodic inspection and handling after problems occur, resulting in high management costs. Summary of the Invention

[0004] To address this, the present invention provides a smart ordering board with a nano-coating and a remote updating system, which overcomes the technical bottleneck that the active ingredients of traditional coatings can only be consumed once in the prior art, while also achieving the problem of long-lasting antibacterial function.

[0005] To achieve the above objectives, the present invention provides a smart ordering board with a nano-coating, the smart ordering board with the nano-coating comprising: An ultra-thin, high-transparency protective layer, a light-triggered regeneration nanocomposite coating, a micro / nano structured glass substrate, and a smart module, among which: The micro-nano structured glass substrate is a micro-nano structured interface that has undergone micro-nano processing, and the micro-nano structured interface has a three-dimensional micro-pore array. The light-triggered regenerative nanocomposite coating includes a contact response layer and an anchoring reserve layer. The anchoring reserve layer is filled with liquid phase and solidified in the three-dimensional micro-pore array of the micro-nano structure interface on the micro-nano structure glass substrate to form a micro-nano scale mechanical interlocking structure. The anchoring reserve layer contains a library of photoactive nanomaterials. An ultrathin photothermal conversion transparent hydrophobic polymer is coated on the anchoring reserve layer to obtain the contact response layer. The intelligent module incorporates a light trigger module, an environmental sensing module, and a remote update system for the intelligent ordering board with a nano-coating. This system monitors the status parameters of the intelligent ordering board in real time and transmits these parameters to the remote update system for remote updating of the intelligent ordering board.

[0006] Furthermore, in the micro-nano structured glass substrate, the individual pores in the three-dimensional micro-pore array on the micro-nano structure interface are inverted pyramid-shaped, with a depth of D1 of 5 micrometers ≤ D1 ≤ 100 micrometers and an opening width of D2 of 1 micrometer ≤ D2 ≤ 20 micrometers, and the three-dimensional micro-pore array is regularly arranged.

[0007] Furthermore, the phototriggered regeneration nanocomposite coating is a gradient functional material. The portion of the gradient functional material filling the pores of the micro-nano structure interface constitutes an anchoring reserve layer, and the ultrathin photothermal conversion transparent hydrophobic polymer layer on top constitutes a contact response layer. The contact response layer is doped with photothermal conversion nanoparticles.

[0008] Furthermore, the light triggering module in the intelligent module includes a specific wavelength light source, a light guide element, and a driving circuit, wherein the emission peak wavelength of the specific wavelength light source matches the photoresponse band of the photoactive nanomaterial library.

[0009] On the other hand, the present invention also provides a remote update system for a smart order card with a nano-coating, the remote update system for the smart order card with a nano-coating comprising: The local data acquisition module is used to acquire operational data of the smart ordering board with nano-coating; The update identification module is used to identify the update requirements of the smart ordering board with nano-coating based on the running data, and to activate the user and firmware parameter update module and the nano-coating update module according to the update requirements. The user and firmware parameter update module is used to obtain user and firmware parameter update data packets and update user parameters and firmware parameters according to the user and firmware parameter update data packets. The coating maintenance and update module is used to obtain coating update data packages, update coating parameters according to the coating update data packages, monitor coating parameters, and optimize the coating update process based on the monitoring results.

[0010] Furthermore, when the update identification module identifies the update requirement of the smart ordering board with nano-coating based on the operating data, it compares the user parameter version, firmware parameter version, and coating parameter version of the ordering board in the operating data with the user parameter version, firmware parameter version, and coating parameter version of the ordering board in the cloud, respectively. Based on the comparison results, it determines the update requirement of the smart ordering board with nano-coating, and activates the user and firmware parameter update module and the nano-coating update module based on the determination results. When the user parameter version of the order card is consistent with the user parameter version of the cloud order card, the firmware parameter version of the order card is consistent with the firmware version of the cloud order card, and the coating parameter version of the order card is consistent with the coating parameter version of the cloud order card, it is determined that the update requirement of the smart order card with nano-coating is not required, and the user and firmware parameter update module and the nano-coating update module are not activated. When the user parameter version of the order card is inconsistent with the user parameter version of the order card in the cloud, it is determined that the update requirement of the smart order card with nano-coating is to update the user parameters and activate the user and firmware parameter update module. When the firmware parameter version of the order card is inconsistent with the firmware parameter version of the order card in the cloud, it is determined that the update requirement of the smart order card with nano-coating is to update the firmware parameters and activate the user and firmware parameter update module. When the coating parameter version of the order form is inconsistent with the coating parameter version of the order form in the cloud, it is determined that the smart order form with nano-coating needs to be updated, and the nano-coating update module is activated.

[0011] Furthermore, when the update identification module activates the user and firmware parameter update module and the nano-coating update module according to the update requirements, it selects the activation process for the user and firmware parameter update module and the nano-coating update module based on the operating status of the smart ordering board with nano-coating, wherein: When the smart ordering board with nano-coating is in an idle period, the process of activating the user and firmware parameter update module and the nano-coating update module will be selected as immediate activation; When the smart ordering board with nano-coating is not in an idle period, the process of activating the user and firmware parameter update module and the nano-coating update module will be selected as waiting for activation.

[0012] Furthermore, when the user and firmware parameter update module updates the user parameters and firmware parameters according to the user and firmware parameter update data packet, it sends a request for obtaining the user and firmware parameter update data packet to the cloud. The cloud transmits the encrypted user and firmware parameter update data packet to the user and firmware parameter update module. The user and firmware parameter update module decrypts the encrypted user and firmware parameter update data packet to obtain the user and firmware parameter update data packet, and updates the user parameters and firmware parameters according to the user and firmware parameter update data packet. When the coating maintenance and update module updates the coating parameters according to the coating update data packet, it sends a coating update data packet retrieval request to the cloud. The cloud transmits the encrypted coating update data packet to the coating maintenance and update module. The coating maintenance and update module decrypts the encrypted coating update data packet to obtain the coating update data packet, and updates the coating parameters according to the coating update data packet.

[0013] Furthermore, when the coating maintenance and update module monitors the coating parameters, it acquires the coating parameters obtained in real time by the local data acquisition module, compares the effective material quantity K of the photoactive nanomaterial library in the coating parameters with the effective material quantity replacement threshold K0, and optimizes the coating update process when K≤K0. The optimization method is as follows: while updating the coating parameters according to the coating update data package, a photoactive nanomaterial library replacement reminder is sent to the administrator terminal, and the administrator replaces the photoactive nanomaterial library. When the coating maintenance and update module monitors the coating parameters, it also acquires the coating replacement time T, compares the coating replacement time T with the theoretical time T0, and determines that the consumption of the photoactive nanomaterial library is abnormal when T < T0. At this time, it acquires the actual change ΔK and the theoretical change ΔK1 of the effective material quantity K of the photoactive nanomaterial library in the coating parameters. Based on the actual change ΔK and the theoretical change ΔK1, it calculates the actual-theoretical difference KK1, sets KK1 = ΔK - ΔK1, and judges the change of the photoactive nanomaterial library based on the actual-theoretical difference KK1. The optimization process is adjusted according to the judgment, wherein: The preset actual-theoretical difference is set to KK0; When 0≤KK1<KK0, the change in the photoactive nanomaterial library is considered to be within the normal range, and no adjustment is made to the optimization process. When KK1≥KK0, the change in the photoactive nanomaterial library is determined to be a risk of leakage. The optimization process is adjusted by stopping the coating update and stopping the operation of the smart ordering board with nano-coating. At the same time, a device material leakage reminder is sent to the administrator terminal, and the administrator is responsible for inspecting and repairing the smart ordering board with nano-coating. When KK1 < 0, the change in the photoactive nanomaterial library is determined to be an abnormal coating parameter data. The coating parameters are then reacquired and tested.

[0014] Furthermore, when monitoring the coating parameters, the coating maintenance and update module also inputs the contact materials of the menu cards into the vulnerable component analysis model. The vulnerable component analysis model outputs the vulnerable component risk level of each contact material of the menu cards. The vulnerable component risk level of each contact material of the menu cards includes high vulnerability level, medium vulnerability level, low vulnerability level, and no vulnerability level. The coating maintenance and update module judges the validity of the preset actual theoretical difference KK0 based on the vulnerable component risk level of each contact material of the menu cards, and corrects the preset actual theoretical difference KK0 according to the judgment result, wherein: Remove the non-vulnerable category from the risk level of vulnerable components of materials that come into contact with each menu item; When the number of highly vulnerable components in the risk level of the materials in contact with each menu item is greater than or equal to 1, the validity of the preset actual theoretical difference KK0 is deemed invalid, and the preset actual theoretical difference KK0 is corrected. When the number of medium-vulnerability level components in the risk level of vulnerable components of each menu contact material is greater than or equal to 3, the validity of the preset actual theoretical difference KK0 is determined to be invalid, and the preset actual theoretical difference KK0 is corrected. When the number of medium-vulnerability risk levels in the vulnerable components of the contact materials of each menu item is greater than or equal to 6, the validity of the preset actual theoretical difference KK0 is deemed invalid, and the preset actual theoretical difference KK0 is corrected. When the coating maintenance and update module corrects the preset actual theoretical difference KK0, it sets the corrected preset actual theoretical difference to KK0`, where KK0` = [100% + 5% × Gg + 3% × (Gz - 2) + 1% × (Gd - 5)] × KK0. When Gg < 1, Gg = 0; when Gz < 3, Gz = 0; and when Gd < 6, Gd = 0. The optimization process is adjusted according to the corrected preset actual theoretical difference KK0`.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: the smart ordering card with nano-coating provides physical protection and high light transmittance through an ultra-thin, high-transparency protective layer; it provides long-lasting antibacterial and hydrophobic functions through a photo-triggered regenerative nanocomposite coating and achieves functional regeneration through a photo-triggered mechanism; it provides a robust micro-nano mechanical interlocking bearing interface for the coating through a micro-nano structured glass substrate; and it realizes intelligent ordering interaction, coating status monitoring, photo-triggered regeneration control, and remote system updates and maintenance through an intelligent module. In particular, the smart ordering card with nano-coating isolates external physical wear and contamination through the ultra-thin, high-transparency protective layer; and achieves long-lasting antibacterial and self-cleaning functions through the photo-triggered regenerative nanocomposite coating. Its gradient design combined with the photo-triggered regeneration mechanism not only provides immediate hydrophobic and antibacterial functions but also can safely excite a deep photoactive nanomaterial library to achieve… The directional migration and functional repair of active ingredients to the surface solves the bottleneck of the one-time consumption of active ingredients in traditional coatings, achieving long-lasting antibacterial function. The smart ordering card with nano-coating achieves ultra-high strength bonding between the coating and the substrate through a micro-nano structured glass substrate. The mechanical interlocking structure formed by its micro-nano structure interface and anchoring reserve layer improves the coating bonding method from surface adhesion to volume integration, enhancing the mechanical stability of the coating against shear and peel, thus enabling it to withstand long-term high-frequency physical friction and cleaning. The smart ordering card with nano-coating realizes intelligent management and maintenance of the entire device through an intelligent module. It integrates a light trigger module, an environmental sensing module, and a remote update system to realize real-time monitoring of the coating status, intelligent maintenance decisions, and remote optimization and upgrading of strategies. This gives the device adaptive and evolvable intelligent management capabilities, significantly improving maintenance efficiency and reducing the total life cycle cost. In particular, the remote update system for the nano-coated smart ordering card collects real-time and comprehensive device operation data through the local data acquisition module, providing an accurate and timely data foundation for the intelligent decision-making of the remote update system. This is a prerequisite for achieving precise and personalized updates. The remote update system for the nano-coated smart ordering card utilizes a dual judgment mechanism of multi-version comparison and operational status perception in the update identification module to accurately identify update needs and intelligently schedule update timing. This ensures the necessity of updates while minimizing interference with normal device operation, improving the practicality and user experience of updates. Furthermore, the remote update system for the nano-coated smart ordering card employs encrypted transmission and security verification mechanisms in the user and firmware parameter update module. To ensure the integrity and security of updated data during transmission and installation, prevent data tampering and theft, and ensure reliable upgrades of the equipment's basic functions, the remote update system for the nano-coated smart ordering board utilizes the coating maintenance and update module for in-depth monitoring and intelligent analysis of coating parameters. This not only enables remote dynamic updates of coating maintenance strategies but also innovatively introduces an optimization and anomaly warning mechanism based on consumption rate monitoring and contact material risk assessment. This allows the system to promptly detect abnormal material consumption, potential leakage risks, and changes in the external environment, and dynamically adjust maintenance strategies and alarm thresholds. Consequently, the maintenance mode of the smart ordering board shifts from post-repair to pre-emptive warning and optimization, greatly improving equipment reliability and lifespan, and reducing operational risks caused by sudden failures.

The anchoring reserve layer 202 is filled with liquid phase and solidified in the three-dimensional micro-pore array of the micro-nano structure interface on the micro-nano structure glass substrate 3 to form a micro-nano scale mechanical interlocking structure. The anchoring reserve layer 202 contains a library of photoactive nanomaterials. An ultrathin photothermal conversion transparent hydrophobic polymer is coated on the anchoring reserve layer 202 to obtain the contact response layer 201. The intelligent module 4 has a built-in light trigger module, an environmental sensing module, and a remote update system for the intelligent ordering board with nano-coating. It is used to monitor the status parameters of the intelligent ordering board in real time and transmit the status parameters to the remote update system for the intelligent ordering board with nano-coating to remotely update the intelligent ordering board.

[0022] Specifically, the smart ordering card with nano-coating is applied in catering service venues. The smart ordering card with nano-coating provides physical protection and high light transmittance through an ultra-thin, high-transparency protective layer 1. A photo-triggered regenerative nanocomposite coating 2 provides long-lasting antibacterial and hydrophobic functions and achieves functional regeneration through a photo-triggered mechanism. A micro-nano structured glass substrate 3 provides a robust micro-nano mechanical interlocking interface for the coating. A smart module 4 enables intelligent ordering interaction, coating status monitoring, photo-triggered regeneration control, and remote system updates and maintenance. In particular, the smart ordering card with nano-coating isolates itself from external physical wear and contamination through the ultra-thin, high-transparency protective layer 1. The photo-triggered regenerative nanocomposite coating 2 achieves long-lasting antibacterial and self-cleaning functions on the surface. Its gradient design combined with the photo-triggered regeneration mechanism not only provides immediate hydrophobic and antibacterial functions but also can safely excite deep photoactive nanomaterials through light.

At the same time, the ultra-thin high-transparency protective layer 1 and the contact response layer 201 provide immediate hydrophobic, anti-fouling, and antibacterial protection. The environmental sensing module in the smart module 4 monitors the status parameters in real time. When long-term use causes the active ingredients on the surface of the contact response layer 201 to be naturally consumed due to physical friction, the system enters the intelligent maintenance stage: the remote update system of the smart ordering board with nano-coating intelligently judges the degree of coating function decay and automatically activates the light trigger module when the device is idle. The light of a specific wavelength passes through the ultra-thin high-transparency protective layer 1, which excites the photothermal conversion nanoparticles in the contact response layer 201 to generate micro-heat, and further triggers the photoactive nanomaterial library in the anchoring reserve layer 202 to respond, driving the functional active substances stored in the photoactive nanomaterial library to migrate directionally to the surface of the contact response layer 201, thereby repairing and regenerating the antibacterial and hydrophobic functions of the surface.

[0038] Specifically, when the coating maintenance and update module updates the coating parameters according to the coating update data packet, it sends a coating update data packet acquisition request to the cloud. The cloud transmits the encrypted coating update data packet to the coating maintenance and update module. The coating maintenance and update module decrypts the encrypted coating update data packet to obtain the coating update data packet and updates the coating parameters according to the coating update data packet. When the coating maintenance and update module monitors the coating parameters, it acquires the coating parameters obtained in real time by the local data acquisition module, compares the effective material quantity K of the photoactive nanomaterial library in the coating parameters with the effective material quantity replacement threshold K0, and optimizes the coating update process when K≤K0. The optimization method is as follows: while updating the coating parameters according to the coating update data package, a photoactive nanomaterial library replacement reminder is sent to the administrator terminal, and the administrator replaces the photoactive nanomaterial library. When the coating maintenance and update module monitors the coating parameters, it also acquires the coating replacement time T, compares the coating replacement time T with the theoretical time T0, and determines that the consumption of the photoactive nanomaterial library is abnormal when T < T0.

The vulnerable component risk level of each contact material of the menu cards includes high vulnerability level, medium vulnerability level, low vulnerability level, and no vulnerability level. The coating maintenance and update module judges the validity of the preset actual theoretical difference KK0 based on the vulnerable component risk level of each contact material of the menu cards, and corrects the preset actual theoretical difference KK0 according to the judgment result, wherein: Remove the non-vulnerable category from the risk level of vulnerable components of materials that come into contact with each menu item; When the number of highly vulnerable components in the risk level of the materials in contact with each menu item is greater than or equal to 1, the validity of the preset actual theoretical difference KK0 is deemed invalid, and the preset actual theoretical difference KK0 is corrected. When the number of medium-vulnerability level components in the risk level of vulnerable components of each menu contact material is greater than or equal to 3, the validity of the preset actual theoretical difference KK0 is determined to be invalid, and the preset actual theoretical difference KK0 is corrected. When the number of medium-vulnerability risk levels in the vulnerable components of the contact materials of each menu item is greater than or equal to 6, the validity of the preset actual theoretical difference KK0 is deemed invalid, and the preset actual theoretical difference KK0 is corrected. When the coating maintenance and update module corrects the preset actual theoretical difference KK0, it sets the corrected preset actual theoretical difference to KK0`, where KK0` = [100% + 5% × Gg + 3% × (Gz - 2) + 1% × (Gd - 5)] × KK0.

For example, the vulnerable component analysis model can be set to be trained using a machine learning classification algorithm based on historical maintenance data and a material chemical property database. The elimination of non-vulnerability grades in the risk classification refers to ignoring material types that are assessed by the model as not causing damage to the coating when calculating the number of risk grades for threshold correction. This embodiment is based on laboratory simulated contact acceleration testing, and statistical analysis of the experimental data from these tests shows that when Gg ≥ 1, for each highly vulnerable grade, the preset actual theoretical difference KK0 increases by 5%; when Gz < 3 grades, the variation range of the preset actual theoretical difference KK0 is small and negligible; when Gz ≥ 3 grades, for each moderately vulnerable grade, the preset actual theoretical difference KK0 increases by 3%; when Gd < 6 grades, the variation range of the preset actual theoretical difference KK0 is small and negligible; when Gd ≥ 6 grades…For each low vulnerability level present, the preset actual theoretical difference KK0 increases by 1%. The aforementioned 5%, 3%, and 1% are determined through statistical analysis of experimental data from laboratory simulated contact acceleration tests. The method for laboratory simulated contact acceleration tests involves exposing the light-triggered regenerated nanocomposite coating to different types of menu board contact materials and quantitatively measuring the actual impact of menu board contact materials with different vulnerability risk levels on the actual change ΔK of the photoactive nanomaterial library, thereby fitting values ​​of 5%, 3%, and 1%.

[0040] Specifically, the coating maintenance and update module, through in-depth monitoring and intelligent analysis of coating parameters, not only enables remote dynamic updates of coating maintenance strategies, but also innovatively introduces an optimization and anomaly early warning mechanism based on consumption rate monitoring and contact material risk assessment. This allows the system to promptly detect abnormal material consumption, potential leakage risks, and changes in the external environment, and dynamically adjust maintenance strategies and alarm thresholds. This transforms the maintenance mode of the smart ordering board from post-repair to pre-warning and optimization, greatly improving the reliability and service life of the equipment and reducing operational risks caused by sudden failures.
