Description

Technical Field

[0001] This utility model belongs to the field of tag technology, specifically relating to an NFC timing tag. Background Technology

[0002] In daily life, people often encounter scenarios that require timed functions, such as monitoring the shelf life of homemade foods. Homemade foods, such as sausages, pickles, sauces, and rice wine, either have long production cycles or long storage periods. Consuming them before or after their expiration date may cause food poisoning or affect their flavor, making time control particularly important. However, due to the long timeframes involved, people often overlook specific times. Even if production information is recorded on paper, it may be lost or damaged by stains on food containers, rendering the information invalid and making it difficult to monitor the normal edible time of homemade foods.

[0003] Especially for homemade foods, foods prepared at different times may be stored in the same area. If the wrong food is identified, it is possible to accidentally eat food that is not fresh or not ready to be used. Utility Model Content

[0004] This invention provides an NFC timing tag to solve the technical problem in the prior art where people lack reliable timing devices that can be matched with items that require time monitoring in their daily lives. This utility model includes: a transparent shell; The chip assembly, housed within the transparent housing, includes: a PCB board; The NFC module is located on the PCB board; At least one LED chip is disposed on the PCB board; The power supply is located on the PCB board; The MCU module is mounted on the PCB board; The NFC module and the LED are respectively connected to the communication interface of the MCU module.

[0005] This invention uses an NFC module for information exchange, stores the information in an MCU module, calculates the time period, and displays different situations through LED beads for easy time monitoring.

[0006] Furthermore: the transparent housing includes an upper cover and a lower cover, which are connected by a threaded connection or an interference fit bayonet connection; The lower cover is also provided with a groove, which is square and has a chamfered corner. The edge opposite the chamfer is also provided with a protrusion. The chip assembly is adapted to the groove, and the beneficial effects of this step are: the detachable transparent shell facilitates the installation and replacement of the power supply, and the groove ensures the stable installation of the chip assembly.

[0007] Furthermore: the transparent shell is provided with perforations; The transparent shell has double-sided adhesive on one or both sides. The beneficial effect of this step is that it provides two ways to bind to items that need to be timed: lanyard connection and adhesive bonding.

[0008] Furthermore: the upper cover is a concave lens, and the concave lens faces the lamp bead. The beneficial effect of this step is that the concave lens has the ability to scatter light, which can spread the light emitted by the lamp bead to a wider range and make it easier for people to see.

[0009] Furthermore: the power source is a button battery, which is connected to the PCB board via a slot. The advantages of this step are: the replaceable power source can improve the service life of the product, eliminates the need for charging, reduces the number of charging ports, and improves sealing.

[0010] Furthermore: when there is only one LED, the LED is a full-color LED; When there are two or more LED beads, the LED beads are monochrome LED beads. The beneficial effect of this step is that they can emit light of different colors, and people can judge the time based on the color of the light.

[0011] The beneficial effects of this utility model are: 1. This application can provide light of different colors, and the time of an item can be determined by its color; 2. It can be connected to items by hanging ropes or adhesive, which can maintain a one-to-one correspondence with the items that need to be monitored over time, avoiding misidentification; 3. Most existing daily timers use a specific point in time as the timing node and only maintain timing for a short period of time. They will automatically cancel if the timing is maintained for too long. However, this application can maintain timing for a longer period of time. Attached Figure Description

[0020] Implementation of this application, for example Figure 1 As shown, this application provides an NFC timing tag.

[0021] This application includes: a transparent shell 1, preferably made of flame-retardant plexiglass, which balances strength, safety and light transmittance, and does not affect signal transmission and light propagation; The chip assembly, housed within the transparent housing 1, includes: a PCB (printed circuit board) board 2; NFC (Near Field Communication) module 3 is mounted on the PCB board 2; At least one LED chip 4 is disposed on the PCB board 2; Power supply 5 is located on the PCB board 2; MCU (Microcontroller Unit) module 6 is mounted on the PCB board 2; The NFC module 3 and the LED bead 4 are respectively connected to the communication interface of the MCU module 6.

[0022] In this invention, the PCB board 2 serves as the carrier for all components and provides the connection circuits between them. The NFC module is used as the information transmission carrier because NFC-enabled mobile phones have the highest penetration rate in daily life. By setting up an app or mini-program on the phone, information such as the production date and shelf life of items can be recorded. Then, information is exchanged through the phone's NFC function and the NFC module, storing the information in the MCU module. The MCU module calculates the time period and displays different situations through LED beads, facilitating time monitoring. The NFC module and MCU module are existing technologies and will not be described in detail.

[0023] For example, taking pickled vegetables as an example, the time of entering the vat is taken as the starting point, the pickling time is the process time period A, and the edible time is the process time period B. During the process time period A, the LED 4 of this application is not lit. When the process time period B arrives, the LED 4 can be a long-interval flashing green light. After the process time period B, the LED 4 is a long-interval flashing red light. In addition, a signal for monitoring the power supply can be set, such as a short-interval flashing yellow light.

[0024] Based on the above technical solution, the transparent shell 1 includes an upper cover and a lower cover, which are connected by a threaded connection or an interference fit bayonet connection. The lower cover is also provided with a groove 11, which is square and has a chamfer 111 at one corner. The edge opposite to the chamfer 111 is also provided with a protrusion 112. The chip assembly is adapted to the groove 11. The detachable transparent shell 1 facilitates the installation and replacement of the power supply 5. The groove 11 ensures the stable installation of the chip assembly and has a foolproof function. In order to further improve the stability of the chip assembly, foam pads 7 are also provided in the blank spaces on the front and back of the PCB board 2 to fill the gap between it and the transparent shell 1.

[0025] Based on the above technical solution, the transparent shell 1 is provided with a perforation 12; The transparent shell 1 has double-sided adhesive on one or both sides, providing two ways to bind it to items that need to be timed: lanyard connection and adhesive bonding.

[0026] Based on the above technical solution, the upper cover is a concave lens, which faces the lamp bead 4. The concave lens has the ability to scatter light, which can diffuse the light emitted by the lamp bead 4 to a wider range and make it easier for people to see.

[0027] Based on the above technical solution, the power source 5 is a button battery. The button battery is connected to the PCB board 2 through a slot. The replaceable power source 5 can improve the service life of this product, eliminate the need for charging, reduce the number of charging ports, and improve the sealing performance.

[0028] Based on the above technical solution, when there is only one LED bead 4, the LED bead 4 is a full-color LED bead; When there are two or more LED beads 4, each LED bead 4 is a monochrome LED bead that can emit light of different colors, allowing people to judge the time based on the color of the light.
