SIGNAL PROCESSING METHOD AND SYSTEM USING NEAR FIELD COMMUNICATION TECHNOLOGY

摘要

Disclosed are a signal processing method and device using near field communication technology. The device includes a near field communication (NFC) card reader, and an NFC card and a signal measurement module connected to each other and installed in a circuit under test. The NFC card is configured to obtain a feed through the near field communication card reader, trigger the signal measurement module to perform signal measurement on the circuit under test and return a signal parameter. The signal measurement module is configured to perform signal measurement on the circuit under test after receiving a trigger signal from the NFC card and feed back the measured signal parameter to the NFC card. The NFC card reader is configured to acquire the signal parameter from the NFC card. In the present solution, an external card reader can read the signal value of the circuit under test conveniently at any time, avoiding the difficulty of wiring and the need for wired power supply, and solving the problem that the working procedure of conventional signal tracking technology is complicated.
