Description

Technical Field

[0001] This utility model relates to the fields of anti-counterfeiting, traceability, and temperature measurement in clothing, specifically a temperature measurement label. Background Technology

[0002] Clothing, a general term encompassing garments, shoes, and accessories, has become an essential part of daily life, serving not only as clothing but also as a representation of identity, lifestyle, and personal charm. However, with the transformation and upgrading of the clothing industry in recent years, clothing has also expanded into areas such as outdoor sports and adventure. Currently, existing labels, when sewn onto clothing, offer limited functionality and cannot meet the needs of customers in special environments or protect their rights.

[0003] Therefore, those skilled in the art have provided a temperature measurement tag to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a temperature measurement label to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A temperature measuring tag includes a temperature measuring circuit, a reader / writer, and a tag. The temperature measuring circuit includes a chip U1 and a sensor U2 for identification, anti-counterfeiting, and traceability. A capacitor C4 is electrically connected to the sensor U2, and a capacitor C3 is electrically connected to the chip U1. Capacitors C1 and C2 are also electrically connected to the chip U1.

[0007] Furthermore, the tag includes an antenna for receiving and transmitting wireless signals.

[0008] Furthermore, sensor U2 is a sensor with temperature measurement, anti-counterfeiting, and traceability functions.

[0009] Furthermore, sensor U2 is connected to the temperature measurement circuit.

[0010] Furthermore, it also includes a power source for the magnetic field generated when the reader comes into contact with the tag.

[0011] This invention utilizes a temperature sensor built into the label. Energy is obtained by generating an induced current through contact between the reader and the label coil. The temperature signal is then transmitted to a mobile terminal to achieve temperature measurement. This invention can be used for temperature measurement via a mobile terminal and can also be applied to clothing and other items for anti-counterfeiting and traceability purposes.

[0012] Figure 1 This is a schematic diagram of the internal circuit of the temperature measuring tag of this utility model;

[0013] Figure 2 This is a system structure diagram of the sensor of this utility model. Detailed Implementation

[0014] Please see Figure 1 In this embodiment of the present invention, a temperature measuring tag includes a temperature measuring circuit, a reader / writer, and a tag. The temperature measuring circuit includes a chip U1 and a sensor U2 for identification, anti-counterfeiting, and traceability. A capacitor C4 is electrically connected to the sensor U2, a capacitor C3 is electrically connected to the chip U1, and capacitors C1 and C2 are also electrically connected to the chip U1.

[0015] In the above technical solution, the temperature measurement is achieved by the reader and the tag coming into contact and transmitting the data wirelessly to the mobile terminal for processing. At the same time, it can also achieve functions such as anti-counterfeiting and traceability. The sensor U2 adopts the MTS4 sensor from Minyuan Sensing. The IC and chip U1 in the sensor U2 both adopt the FM11NT083 chip from Shanghai Fudan Microelectronics Group Co., Ltd.

[0016] The tag includes an antenna for receiving and transmitting wireless signals.

[0017] Among them, sensor U2 is a sensor with temperature measurement, anti-counterfeiting and traceability functions.

[0018] Sensor U2 is connected to the temperature measurement circuit.

[0019] It also includes a power supply for the magnetic field generated when the reader contacts the tag. The voltage is 3.3V and the power supply method is contact power supply for the reader. During the contact process, it not only powers the sensor U2, but also reads the data fed back by the sensor U2, and obtains the information we need through the processing of the mobile terminal.

[0020] like Figure 2 As shown, the temperature sensor register in sensor U2 contains a two-byte temperature register that stores the digital output from sensor U2. When the tag initiates temperature measurement, the host must rewrite the temperature measurement command register to send a temperature measurement command to the slave device. After the conversion time, the resulting 16-bit temperature data is stored in the first two bytes of the register (Temp_lsb / Temp_lsb). The conversion time is related to the averaging count setting; the more averaging counts, the longer the conversion time.

[0021] The instruction register contains two bytes: a temperature measurement instruction register and an E2PROM instruction register. The temperature measurement instruction register (Temp_Cmd) includes measurement mode and heating function configuration bits, described in detail below:

[0022]

[0023] Upon power-up, the chip defaults to a stopped measurement state, waiting for measurement commands from the host. A single measurement completes only one temperature conversion; after completion, the chip enters sleep mode unless bit 0 of the temperature configuration register (Temp_Cfg) is set to 0. In continuous measurement mode, the chip performs periodic temperature measurements based on bits 7-5 (MPS) of the temperature configuration register (Temp_Cfg). The chip does not enter sleep mode during the interval between conversions, even if bit 0 of the temperature configuration register (Temp_Cfg) is set to 1. In continuous measurement mode, writing 01 to bits 7-6 will cause the chip to exit continuous measurement mode. The temperature measurement status flag is stored in the status register. When temperature measurement is in progress, bit 5 of the status register is 1; when temperature measurement is complete, bit 5 of the status register is 0.

[0024] In this embodiment, sensor U2 is an MTS4 temperature sensor.

[0025] By using a temperature sensor built into the tag, the reader generates an induced current through contact with the tag coil, and transmits the read temperature signal to the mobile terminal to achieve the temperature measurement function. In addition to temperature measurement via the mobile terminal, it can also be used on clothing and other items for anti-counterfeiting, traceability and other characteristics.
