Abstract

The invention discloses a wirelessly charged sensor node. The node mainly comprises a printed circuit board (PCB) antenna, a radio frequency front end module, a microprocessor module, a sensor module and a wireless radio frequency module, wherein the PCB antenna is connected with the radio frequency front end module; the radio frequency front end module is connected with the microprocessor module through a voltage-stabilizing submodule; and the microprocessor module is connected with the sensor module through an input and output (IO) port, and is connected with the wireless radio frequency module through a serial peripheral interface (SPI). The sensor node not only can be wirelessly charged, but also can acquire data of various sensors and send the data out through wireless radio frequency chips.

Description

technical field

[0001] The invention relates to a novel wireless sensor node which integrates radio frequency identification wireless charging function and sensor node acquisition sensor data function without battery power supply. Background technique

[0002] The development of semiconductor technology and computer technology has made great research and application of Wireless Sensor Network (WSN) and Radio Frequency IDendification (RFID). The sensor network is mainly composed of sensor nodes, and the monitoring of a specific sensor parameter can be completed through the reasonable arrangement of sensor nodes. The sensor node is roughly composed of three parts: sensor, microprocessor, and radio frequency module. The sensor transmits the collected sensing signal to the microprocessor for processing. After processing, the data is sent to another node or the host computer through the radio frequency module. . RFID technology is mainly composed of two parts - reader and tag. ...
