DETECTION SYSTEM AND SIGNAL ACQUISITION DEVICE

WIPO Patent Application WO/2021/179974

A1

The embodiments of the present application relate to the technical field of monitoring, and proposed are a detection system and a signal acquisition device. The detection system comprises a signal acquisition device and a reader/writer, the signal acquisition device comprises a passive inductive coil sensor, the reader/writer comprises an antenna and a read/write chip, and the passive inductive coil communicates with the read/write chip by means of the antenna; the read/write chip sends a preset carrier signal to the passive inductive coil sensor by means of the antenna; the passive inductive coil sensor generates a detection signal according to a change in a physical sign of a detected object, and modulates the detection signal and the preset carrier signal to obtain a modulated signal, and the modulated signal is sent to the read/write chip by means of the antenna; and the read/write chip obtains a physical sign signal of the detected object according to the modulated signal. The detection system and the signal acquisition device have the advantages of a small volume and a simple circuit design.
