Problems solved by technology

[0003] However, high-frequency work will directly affect the working temperature of the RFID read-write module. If there is no effective means of temperature control, in order to protect the life of the RFID read-write module, only the working power of the RFID read-write module can be specified to control its read-write distance. RFID card, thus limiting the use of RFID read and write modules

Abstract

The invention relates to a method and a device for the temperature control of an RFID read/write module. The device is used for controlling the working temperature of an RFID read/write module, and comprises an intelligent power supply module, a micro processing module and a temperature sensor, wherein the intelligent power supply module is connected to the RFID read/write module by a power cord and a ground wire; the power cord is provided with a current sensor, and a voltage sensor is arranged between the power cord and the ground wire; the temperature sensor is used for detecting the working temperature value of the RFID read/write module; and the micro processing module comprehensively judges the current temperature state of the RFID read/write module based on the temperature, and control the intelligent power supply module to change the input voltage of the RFID read/write module. By detecting the working temperature and the current intensity of the RFID read/write module in real time and adjusting the working voltage control temperature of the RFID read/write module in real time, the invention ensures that the RFID read/write module is in the high-efficiency operating state all the time, thereby widening the application of the RFID read/write module.

Description

technical field [0001] The invention relates to an RFID read-write module, in particular to a temperature control method and device for the RFID read-write module. Background technique [0002] The radio frequency identification (Radio Frequency Identification, RFID) read-write module can be used to read the data on the RFID card, and send it to the corresponding application program for processing. The power of the RFID read-write module is directly proportional to the read-write distance. Try to keep the RFID read-write module at high power, which can effectively improve the recognition performance of the RFID read-write module. [0003] However, high-frequency work will directly affect the working temperature of the RFID read-write module. If there is no effective means of temperature control, in order to protect the life of the RFID read-write module, only the working power of the RFID read-write module can be specified to control its read-write distance. RFID cards, the...
