Embodiment Construction
[0052] In order to make the object, technical solution and advantages of the present invention more clear, preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown. However, the present invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0053] For the temperature history of special items during storage, it is possible to digitize the electrical signal corresponding to the ambient temperature output by the measurement circuit by integrating a semiconductor temperature sensor on the radio frequency tag, and use the proprietary extension command of the radio frequency tag identification system to transmit ...

The invention discloses a temperature-sensing radio-frequency tag and a method and system for judging whether the temperature variation of the radio-frequency tag exceeds a permission range or not. The radio-frequency tag comprises an antenna, an integrated circuit connected with the antenna, and at least one temperature sensor, wherein the temperature sensor comprises two capacitor plates, a dielectric material, a dielectric packaging material, a structure material and a removable structure; the dielectric material is a volatile dielectric with a solid state and a liquid state and is packaged in a closed space defined by the two capacitor plates and the structure material through the dielectric packaging material on the structure material; the removable structure is removable; the two capacitor plates of at least one temperature sensor lead out two plate connection signal to be connected with the integrated circuit of the radio-frequency tag, so that the integrated circuit of the radio-frequency tag can be used to measure a capacitance value between the two capacitor plates of the temperature sensor.
Description
technical field [0001] The invention relates to the technical fields of temperature measurement and radio frequency identification, in particular to a temperature-sensing radio frequency tag and a method and system for determining whether the change of its storage temperature exceeds the allowable range. Background technique [0002] Compared with ordinary barcodes, radio frequency tags (RF Tags) have many advantages such as high access speed, parallel batch access, two-way data transmission and stored data reading and writing. Therefore, radio frequency tags have been widely used for identification of various items. [0003] According to whether the radio frequency tag is powered by a battery or not, the radio frequency tag can be divided into two types: active tag and passive tag. The passive tag can only work when the reader is in the process of identification. [0004] For some special items during the transmission process, it is necessary to use an incubator or similar...
