Description

Technical Field

[0001] The utility model relates to the technical field of readers, in particular to a weather-resistant radio frequency reader module. Background Technique

[0002] A reader is generally considered to be a reading and writing terminal device for radio frequency identification, i.e., RFID. It can not only read radio frequency tags but also erase and write data, so it is called a reader. A typical reader terminal generally consists of three parts: an antenna, a radio frequency interface module, and a logic control module.

[0003] The shell of the existing radio frequency reader is made of stainless steel material, and its anti-corrosion performance is relatively poor. It is easy to be corroded and damaged when used in harsh environments such as industrial and mining areas and oil wells. For this reason, we propose a weather-resistant radio frequency reader module.
