The invention relates to a temperature control method and device for an RFID read-write module. The device is used to control the working temperature of the RFID read-write module, and includes an intelligent power supply module and a micro-processing module. The intelligent power supply module is connected to the RFID through a power line and a grounding line. Read-write module; a current sensor is set on the power line, and a voltage sensor is set on the time between the power line and the ground line; it also includes a temperature sensor for detecting the working temperature value of the RFID read-write module; the micro-processing module comprehensively judges the current RFID reading The temperature state of the writing module controls the intelligent power supply module to change the input voltage of the RFID reading and writing module. The present invention detects the working temperature and current of the RFID read-write module in real time, adjusts its working voltage to control the temperature in real time, and ensures that the RFID read-write module can always be in a high-efficiency working state, making the RFID read-write module more widely used.
Description
technical field [0001] The invention relates to an RFID read-write module, in particular to a temperature control device and method 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...
