Embodiment Construction

[0021] A method for tracking the service life of electronic and electrical products. It connects an RFID microchip with an antenna coil to the working power supply of the electrical product. In the EEPROM of the belt, the matching read-write device is close to the antenna coil, and the data in the EEPROM is written or read through the RF air interface. RFID data writing and reading methods and reading devices are relatively mature technologies.

[0022] The UID serial number is stored in the RFID microchip, and the information of the UID serial number includes product number, batch, sales area, delivery date, etc., and each RFID microchip has a globally unique UID serial number to ensure its uniqueness. , easy to track.

[0023] The device for realizing the above method includes an RFID microchip and an antenna coil that doubles as an RF energy and data transmission interface, the RFID microchip is provided with an external antenna terminal and a power input terminal, and the...

Abstract

The invention discloses a method and device for tracking the service life of electronic and electrical products. In the device, a RFID (Radio Frequency Identification Device) microchip provided with an antenna coil is connected on a working power supply of an electrical product; the RFID microchip is used for recording and calculating the start times and accumulated working time of the working power supply of the electrical product and storing the start times and accumulated working time in a self-carried EEPROM (Electrically Erasable Programmable Read-Only Memory); read-write equipment matched with the RFID microchip approaches the antenna coil, and writes or reads data in the EEPROM through an RF (Radio Frequency) air interface; therefore, the tracking and the acquisition of data information of the service life of the electrical product are realized by adopting RFID means without changing the hardware structure of a circuit of the electrical product; moreover, the device has the advantages of extremely low power consumption, tiny volume, low investment, convenience for installation and simplicity and quickness for operation; the power consumption of the electrical product cannot be increased; the device can be arranged and adhered to the insides of plastic shells of various electrical products; the test result can be obtained as the test is carried out, so that the result is clear; and convenience is provided for the service-life tracking statistics and after-sale maintenance services of the electrical product.

Description

technical field [0001] The invention relates to a method and device for tracking the service life of electronic and electrical products. Background technique [0002] In today's era of digital technology, electronic and electrical products are closely related to people's production and life. Such as all kinds of electronic and electrical products for production, home use, office use, and daily life, ranging from electromechanical production equipment, air conditioners, refrigerators, televisions, computers, printers, network peripheral equipment, test and testing instruments, to small mobile phones , MP3 players, etc., almost everywhere. With its many categories and different uses, electronic and electrical products have greatly enriched and improved people's quality of life. While more and more electrical products have entered factories and homes in a steady stream, the service life of electrical products It is also receiving more and more attention from designers, produc...
