Abstract
Description
Technical Field
[0001] This application relates to the technical field of warehousing supervision equipment, and particularly to an interactive environmental monitoring label for warehousing. Background Art
[0002] The internal environment of the warehousing system is complex, and the stored goods have different requirements for the warehousing environment. Once the warehousing system is built, it is difficult to additionally arrange a sensing system inside it. The reason is that the internal environment of a large-scale three-dimensional warehousing system is complex, and there are intricate tracks in the high-rise shelves for automatic walking equipment to transport and handle goods. The additional sensor devices need to be additionally designed for their power supply and signal transmission lines. The additional lines are not convenient to arrange and are prone to various problems during the operation of the warehousing system. For example, the electrical contact is unstable due to equipment vibration, or the operation of various devices in the shelves is interfered due to the loosening of the fixing structure. Even if wireless transmission or batteries are used for signal interaction and power supply, once the equipment fails, it will still face the dilemma of being difficult to replace and maintain in a timely manner. Summary of the Invention
[0003] In order to solve the deficiencies of the prior art, the purpose of this application is to provide an interactive environmental monitoring label for warehousing. By integrating a sensing structure into the RFID label in this application, the detection signal of the warehousing environment where the goods are located can be superimposed during the process of the RFID label interacting with the identification information of the goods, so as to realize the flexible detection of the local environment in the warehousing system.
[0004] To achieve the above purpose, the interactive environmental monitoring label for warehousing provided by this application includes: a sticky base, with an adhesive attached to its bottom and a radiation structure provided on its upper surface; a radio frequency chip, which is electrically connected to the radiation structure and fixed on the upper surface of the sticky base; a sensitive material, which is attached to the surface of the radiation structure and completely covers the exposed sticky base surface between the radiation structures.
[0005] Optionally, for the interactive environmental monitoring label for warehousing as described above, the radiation structure is a differential finger structure, or a curve or broken line structure arranged in a serpentine and winding manner.
[0006] Optionally, for the interactive environmental monitoring label for warehousing as described above, the differential finger structure includes: a frame, which is arranged in a rectangle or circle along the edge of the sticky base; strip structures, which extend from the edge of the frame towards the middle, and the strip structures are cross-arranged on the two opposite sides in the frame, and the strip structures are arranged in parallel between each other.
[0007] Optionally, for the interactive environmental monitoring label for warehousing as described above, the radio frequency chip is arranged between two adjacent strip structures extending from both sides of the frame towards the middle.
[0008] Optionally, for any of the above-mentioned interactive environmental monitoring tags for warehousing, wherein the sensitive material is a graphene oxide powder thin film coating.
[0009] Optionally, for any of the above-mentioned interactive environmental monitoring tags for warehousing, wherein the adhesive substrate includes, from top to bottom in layers: a PI film, an adhesive, a metal film, and an adhesive strip.
[0010] Optionally, for any of the above-mentioned interactive environmental monitoring tags for warehousing, wherein the radiation structure is a laser converted graphene structure laser-etched on the surface of the PI film.
[0011] Optionally, for any of the above-mentioned interactive environmental monitoring tags for warehousing, wherein the radiation structure and the RF chip are electrically connected by a condensed and cured conductive silver paste.
[0012] The present application has the following technical effects compared with the existing solutions:
[0013] The interactive environmental monitoring tag for warehousing provided by the present application includes an adhesive substrate for attaching the tag to the surface of warehousing goods. A radiation structure is provided on the upper surface of the adhesive substrate, and an RF chip is provided in the radiation structure. Through the electrical connection between the RF chip and the radiation structure, when the radiation structure receives an external RFID signal, the chip is induced to trigger the radiation structure to output a feedback signal, thereby externally radiating the identification data stored inside the chip. The present application coats a sensitive material on the surface of the radiation structure, which can correspondingly adjust the parasitic impedance state of the radiation structure according to the warehousing environment, so as to superimpose modulation information in response to environmental parameters on the RF signal externally radiated by the radiation structure, for the receiving terminal to obtain the real-time environmental parameters of the warehousing environment where the goods are located through the interaction of the RFID signal. The present application can directly reuse the RFID tag for the detection and interaction of environmental parameters, without separately arranging the sensing and detection units in the warehousing environment. Therefore, it can provide a more convenient and flexible warehousing environment detection solution.

It should be understood that the preferred embodiments described herein are only for illustrating and explaining the present application, and are not used to limit the present application.

[0021] The meaning of "inside and outside" described in the present application refers to, with respect to the radiation structure itself, the direction from the edge of the adhesive substrate to the position where the RF chip is arranged inside the radiation structure is inside, and vice versa; it is not a specific limitation on the device mechanism of the present application.
[0022] The meaning of "left and right" described in the present application refers to, when the user is facing the radiation structure, the left side of the user is the left, and the right side of the user is the right, and it is not a specific limitation on the device mechanism of the present application.

[0024] The meaning of "up and down" described in the present application refers to, when the user is facing the radiation structure, the direction from the adhesive to the RF chip is up, and vice versa, and it is not a specific limitation on the device mechanism of the present application.
[0025] Figure 1 As shown, it is an interactive environmental monitoring label for warehousing provided by the present application, which can be directly pasted on the surface of goods, or on the surface of automatic walking equipment or other operating devices inside the warehouse. The label of the present application can be set to include:
[0026] An adhesive substrate, the bottom of which is attached with an adhesive for attaching the entire label to the surface of the above-mentioned goods or warehousing operating equipment. The upper surface of the adhesive substrate exposed to the outside is provided with a radiation structure 1, and the radiation structure can be flexibly set to different forms according to the detection needs of environmental parameters;
[0027] An RF chip 3, which is electrically connected to the radiation structure 1 and can be fixed on the upper surface of the adhesive substrate by a conductive gel or a welding method;
[0028] The sensitive material 2 is attached to the surface of the radiation structure 1 and completely covers the exposed adhesive substrate surface between the pattern structures of the radiation structure 1. The sensitive material 2 can be flexibly selected as a graphene oxide powder thin film coating according to the detection requirements of environmental parameters.
[0029] For example, when it is necessary to detect the environmental humidity, the radiation structure 1 can usually be set as Figure 2 the shown differential finger structure. Generally, as long as the sensitive material is kept uniformly formulated, under the action of the radio frequency interaction signal, a unified charge transfer characteristic can be formed between the interdigital structures. Thus, a corresponding parasitic inductive reactance is formed between the interdigital structures. This sensitive material can respond to the environmental humidity and change the charge transfer characteristic in the material. Thus, the parasitic inductive reactance between the interdigital structures can change correspondingly in response to the environmental humidity. Therefore, the radiation characteristic of the radiation structure is adjusted, and the response information of the corresponding environmental humidity is superimposed on the echo signal fed back to the radio frequency scanner. By adjusting the amplitude-frequency phase of the radio frequency echo, the radio frequency scanner can obtain the corresponding environmental humidity information according to the echo signal of the tag radiation structure, so as to directly detect the microenvironment where the goods are located through the radio frequency tag.
[0030] When it is necessary to detect the environmental temperature, the radiation structure 1 can usually be set as a curve or broken line structure arranged in a serpentine reciprocating and winding manner. At this time, the sensitive material can generally be selected as a graphene oxide powder thin film coating. Generally, as long as the coating thickness of the sensitive material is kept uniformly formulated, under the action of the radio frequency interaction signal, a unified charge transfer characteristic can be formed between the serpentine structures. Thus, a corresponding parasitic inductive reactance is formed between the serpentine structures. This sensitive material can respond to the environmental temperature and change the charge transfer characteristic in the material. Thus, the parasitic inductive reactance between the serpentine structures can change correspondingly in response to the environmental temperature. Therefore, the radiation characteristic of the radiation structure is adjusted, and the response information of the corresponding environmental temperature is superimposed on the echo signal fed back to the radio frequency scanner. By adjusting the amplitude-frequency phase of the radio frequency echo, the radio frequency scanner can obtain the corresponding environmental temperature information according to the echo signal of the tag radiation structure, so as to directly detect the microenvironment where the goods are located through the radio frequency tag.
[0031] In general application scenarios, the differential finger structure adopted in this application can specifically be set to include:
[0032] A frame that can surround the edge of the adhesive substrate for one week. The structure of the frame can be flexibly set as a rectangle or a circle according to the detection requirements. And, the frame can be provided with several openings according to the inductive reactance matching requirements of the radio frequency chip to adjust the inductive reactance characteristic of the overall radiation unit to match the impedance of the radio frequency chip to obtain better radio frequency performance;
[0033] A strip structure that extends from the inner edge of the frame towards the center of the base structure. The strip structures are generally arranged in a crisscross pattern on the relatively arranged two sides of the frame, and are arranged in parallel between each strip structure to form a finger unit.
[0034] Thus, the RF chip 3 can be electrically fixed through the cured conductive silver glue and arranged between two adjacent strip structures extending from both sides of the frame towards the middle to achieve electrical connection with the radiation structure, and realize the modulation output of the echo signal of the radiation structure.
[0035] To further improve the radiation characteristics of the overall tag structure, the present application can set the adhesive base as: a PI film, an adhesive, a metal film, and a rubber strip arranged layer by layer from top to bottom. The surface of the PI film can be laser-etched to convert the PI material on its surface into a graphene structure, so as to realize the radiation interaction of RF signals through the conductive property of graphene itself. The bottom layer of the PI film can be attached to the metal film through an adhesive, so as to provide a stable level through the metal film, and provide a mirror radiation reflection for the radiation structure through the skin effect of the metal material, thereby enhancing its RF echo and facilitating the detection of the echo signal by the RFID signal gun. The bottom of the metal film can be firmly attached to the surface of the storage goods or the operating equipment inside the storage space through an adhesive.
