Abstract

The present invention proposes a near-field communication test system and method. The test system includes a host computer, a main chip, and an analog front-end. The analog front-end can electromagnetically interact with matching equipment to realize near-field communication; the main chip includes a control unit and a unit, wherein the control unit is connected to the host computer, and analyzes the commands issued by the host computer, and reorganizes the data and sends it to the processing unit, and the connection between the control unit and the processing unit Using an internal high-speed interface connection, the processing unit modulates and demodulates the issued commands and forms a control signal to control the analog front end. The system and method proposed by the present invention realize the compatibility test of the ISO / IEC14443-3 / 4 layer protocol, satisfy the physical performance test requirements of various types of near-field communication terminal equipment in different situations, and make the near-field communication terminal The performance test is more standardized, unified, accurate and has practical application value.

Description

technical field

[0001] The present invention relates to the field of near field communication, in particular to a system and method for testing near field communication equipment. Background technique

[0002] Near Field Communication (NFC) technology was first developed in 2002 by Philips of the Netherlands and Sony of Japan, and is a short-range non-contact identification and interconnection technology jointly promoted by famous manufacturers such as Nokia and Sony. The original 13.56MHz non-contact radio frequency identification (Radio Frequency Identification, RFID) technology and wireless interconnection technology have evolved from integrating RFID readers, RFID tags and point-to-point communication functions, and can identify and data with compatible devices within a short distance. exchange.

[0003] In recent years, with the rapid development of the mobile Internet, the demand for short-range interconnection technology in mobile devices has made NFC technology wide...
