Secondly, the heating temperature of the heating plate 110 can be continuously adjusted to simulate the temperature data collected by the RFID temperature measurement tag 111 at different temperatures, and the different temperature data collected can be compared with the standard temperature data to achieve the test of the temperature calibration ability and high temperature resistance of the product. And the reliability and storage capacity and other performances of the RFID temperature measurement tag 111 can be verified through long-term multiple tests at different temperatures. The specific performance test process and test indicators of the RFID temperature measurement tag 111 are not limited in this application.

[0038] It should be noted that to improve the reliability of the connection between the RFID temperature measurement tag 111 and the heating plate 110, thermal conductive silicone can be coated on the surface of the heating plate 110 to take into account the thermal conductivity of the heating plate 110 and the adhesion to the tag. In addition, the connection method among the test chamber 100, the reader 200, and the host computer 300 in this application is not limited.

[0044] Through the setting of the cooler 160, when the temperature control unit 120 adjusts the temperature of the heating plate 110, it can not only make the heating plate 110 heat up quickly, but also cool it down quickly, which is beneficial to the efficient adjustment of the temperature of the heating plate 110, and to a certain extent, it can reduce the test time of the RFID temperature measurement tag 111 and improve the test efficiency.

[0045] In some embodiments, continue to refer to Figure 3As shown in the figure, the temperature control unit 120 includes a digital display thermometer 121, a relay 122, and a power supply module 123.

[0047] Furthermore, the temperature control unit 120 further includes a temperature sensor 124. The digital display thermometer 121 is connected to the heating plate 110 through the temperature sensor 124. The setting of the temperature sensor 124 can detect the actual temperature of the heating plate 110 in real time, so that the digital display thermometer 121 can display the actual temperature of the heating plate 110 in real time.

[0048] Preferably, the box door 140 is also provided with an installation hole (not shown in the figure) communicating with the working cavity. The digital display thermometer 121 is matched with the installation hole so that the digital display thermometer 121 is exposed outside the box door 140.
