Description

Low Wen Bingpai resistant to RFID signal interference

Technical Field

The utility model relates to a low-temperature ice bank, in particular to a low-temperature ice bank resistant to RFID signal interference.

Background

The ice bank is a novel temperature control device and generally consists of a container with a specific shape and phase change materials filled in the container. Phase change materials are often used for temperature control in specific situations, such as cold chain transport, because they absorb or release a large amount of latent heat at a specific temperature, thereby keeping the ambient temperature relatively stable. The phase change material is packaged in the container, so that leakage pollution and cold capacity loss are avoided in the use process, the phase change material can be repeatedly used, and cold and hot use can be realized according to different working conditions.

The existing ice bank is generally matched with an incubator for use, and has the advantages of large usage amount, high circulation rate and long pretreatment time, and great pressure is caused to sample management and inventory, especially informatization management. The RFID is an informatization management scheme widely used at present, is convenient and quick to use and low in cost, and can read corresponding signals remotely through a reader only by attaching an electronic tag on the surface or inside of a material to be counted, so that the RFID is very suitable for counting and managing a large amount of materials. However, for some mechanical reasons, RFID signals are susceptible to interference from certain substances, such as metals. At present, in ice discharging products for cold chains at ultralow temperature (for example, -20 ℃), phase change materials are usually realized by adopting aqueous solutions of inorganic salts (for example, sodium chloride, potassium chloride and the like), and the phase change materials have low cost and stable performance and are widely applied to the cold chain transportation process at present. However, aqueous solutions of these inorganic salts also have a strong shielding effect on RFID signals. Experimental results show that when several ice rows are stacked together, an RFID tag surrounded by phase change material will hardly be able to read a signal by a reader. This phenomenon has a great influence on the statistics of the low-temperature ice bank, and thus the application of the RFID is greatly limited. In addition, the RFID tag module protrudes from the surface, and thus the problem of falling off or the like is also likely to occur.
