[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figure 1 A passive electronic tag for temperature monitoring includes an RF circuit module 1, a detection circuit module 2, and a temperature fuse 3. The RF circuit module 1 is electrically connected to the detection circuit module 2, and the temperature fuse 3 is connected in series with the detection circuit module 2. The RF circuit module 1 detects the circuit status of the detection circuit module 2.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: After the tag is configured, it senses the temperature change of the monitored item through the temperature fuse 3 of the detection circuit module 2; when the monitored temperature reaches the set temperature, the temperature fuse 3 melts, the circuit state of the detection circuit module 2 changes, so that the information feedback of the radio frequency circuit module 1 when it is identified by the reader changes, thereby realizing the judgment of whether the device is in an over-temperature state, and can make early preventive maintenance and repair; the miniaturized tag design is simple and convenient to configure, has low operating cost, and is suitable for item temperature detection in multiple scenarios.

[0021] Furthermore, the radio frequency circuit module 1 includes a radio frequency antenna 12 and a chip 11, the radio frequency antenna 12 is electrically connected to the chip 11, and the chip 11 is electrically connected to the detection circuit module 2.

[0022] As described above, the energy supplied by the reader is obtained through the radio frequency antenna 12, and the tag information is fed back to the reader through the chip 11. The chip 11 is electrically connected to the detection circuit module 2 to detect the circuit state of the detection circuit module 2 as a result of temperature changes.

[0023] Furthermore, the detection circuit module 2 includes a detection line 21, the two ends of which are connected to the radio frequency circuit module 1, and a thermal fuse 3 is connected in series in the middle.

[0024] As described above, the detection circuit module 1 detects the circuit status of the detection circuit module 2 by connecting the detection line 21 to the radio frequency circuit module 1 and connecting the detection line 21 in series with the thermal fuse 3.

[0025] Furthermore, the detection circuit module 2 also includes a mounting component 22, the temperature fuse 3 is disposed within the mounting component 22, and the mounting component 22 is arranged on the temperature sensing area of ​​the monitored item.

[0026] As can be seen from the above description, the temperature fuse 3 is placed on the temperature sensing area of ​​the monitored item through the mounting component 22, and the radio frequency circuit module 1 does not need to be placed in the temperature sensing area of ​​the monitored item, thus reducing the layout cost.

[0027] Furthermore, the radio frequency circuit module 1 includes an antenna substrate 13, which is made of a high-temperature resistant material.

[0028] As can be seen from the above description, when the detection circuit module 2 and the radio frequency circuit module 1 need to be assembled together in the temperature sensing area of ​​the monitored item, the antenna substrate 13 made of high temperature resistant material can be adapted to its temperature to avoid high temperature damage.

[0029] Furthermore, the radio frequency circuit module 1 includes an antenna substrate 13, on which a high-temperature resistant layer is provided.

[0030] As can be seen from the above description, when the detection circuit module 2 and the radio frequency circuit module 1 need to be assembled together in the temperature sensing area of ​​the monitored item, the antenna substrate 13 with a high temperature resistant layer can be designed to adapt to its temperature and avoid high temperature damage.

[0031] Furthermore, the radio frequency circuit module 1 is an ultra-high frequency band radio frequency circuit module 1.

[0032] As can be seen from the above description, by designing the ultra-high frequency band radio frequency circuit module 1, it has a stronger signal range and communication performance.

[0033] Furthermore, the radio frequency circuit module 1 includes a housing 13, and the detection module is detachably disposed within the housing 13.

[0034] As can be seen from the above description, due to the detachable design of the detection module in the housing 13, the two can be installed together or the detection module can be removed and installed separately, depending on the installation conditions of the temperature sensing area of ​​the tested item.

[0035] Furthermore, the detection line 21 is wound around and disposed within the housing 13.

[0036] As can be seen from the above description, the detection line 21 is designed to be wound up, so the length of the detection line 21 can be adjusted during installation to install the detection module in a suitable position.

[0037] Furthermore, the detection line 21 is provided with a high-temperature resistant layer.

[0038] As can be seen from the above description, the detection line 21 with a high-temperature resistant layer is designed to protect the internal metal conductor and adapt to its temperature, thus preventing the outer layer of the wire harness from being damaged by high temperature, based on the temperature of the monitored item's overheating state.

[0039] Example 1:

[0040] A passive electronic tag for temperature monitoring includes an RF circuit module 1, a detection circuit module 2, and a temperature fuse 3.

[0041] The radio frequency circuit module 1 includes a chip 11, an antenna substrate 13, and a radio frequency antenna 12. The radio frequency circuit module 1 is an ultra-high frequency band radio frequency circuit module 1. The chip 11 and the radio frequency antenna 12 are both disposed on the antenna substrate 13. The radio frequency antenna 12 is electrically connected to the chip 11.

[0042] The detection circuit module 2 includes a detection line 21 and a mounting component 22. The detection line 21 has a high-temperature resistant layer. Both ends of the detection line 21 are connected to the chip 11, and a temperature fuse 3 is connected in series in the middle. The temperature fuse 3 is arranged inside the mounting component 22, which is placed on the temperature-sensing area of ​​the monitored item.

[0043] Example 2

[0044] The difference between this embodiment and Embodiment 1 is that:

[0045] The radio frequency circuit module 1 also includes a housing 13, and the detection module is detachably disposed within the housing 13. The detection line 21 is wound up and disposed within the housing 13. Depending on the installation conditions, the detection module can be disassembled and installed independently, and its length can be adjusted by the wound arrangement of the detection line 21. Alternatively, the detection module and the radio frequency circuit module 1 can be installed together.

[0046] Example 3

[0047] The difference between this embodiment and Embodiment 1 is that:

[0048] The antenna substrate 13 is made of a high-temperature resistant material. When the radio frequency circuit module 1 needs to be placed together with the monitored object, its overheated state may affect the radio frequency circuit module 1, such as the antenna substrate 13. Therefore, high-temperature damage can be avoided by designing a PPC or PCB antenna substrate 13 made of a high-temperature resistant material.

[0049] Example 4

[0050] The difference between this embodiment and Embodiment 1 is that:

[0051] The antenna substrate 13 is provided with a high-temperature resistant layer. When the radio frequency circuit module 1 needs to be placed together with the monitored object, the temperature of its overheated state may affect the radio frequency circuit module 1, such as the antenna substrate 13. Therefore, the antenna substrate 13 with a high-temperature resistant layer is designed to avoid high-temperature damage.

[0052] In summary, the passive electronic tag for temperature monitoring provided by this utility model, after being configured, senses the temperature change of the monitored item through the temperature fuse of the detection circuit module; when the monitored temperature reaches the set temperature, the temperature fuse blows, the circuit state of the detection circuit module changes, and the information feedback of the radio frequency circuit module when it is identified by the reader changes, thereby realizing the judgment of whether the device is in an overheating state, and enabling early preventive maintenance and repair; the miniaturized tag design is simple and convenient to configure, has low operating cost, and is suitable for temperature detection of items in multiple scenarios.
