Wireless acquisition apparatus based on wireless charging

Abstract

The invention discloses a wireless acquisition apparatus based on wireless charging. The wireless acquisition apparatus comprises a power supply circuit, an electric quantity detection circuit, a control circuit, a switch circuit, a receiving coil, a voltage converting circuit, a signal amplification circuit, a shaping circuit, and a transmission interface, the signal amplification circuit is usedfor amplifying an output signal of a sensor, and is shaped through the shaping circuit; the electric quantity detection circuit is used for detecting residual electric quantity of the power supply circuit, the control circuit is used for acquiring the shaped signal to obtain an acquisition signal and output the acquisition signal, the residual electricity magnitude is compared with a set threshold to determine whether wireless charging starts or not, when starting is determined, an excitation signal is output, a switch circuit is used for closing, the electric energy is received through the receiving coil, and the electric energy is transited to stable voltage through a voltage converting circuit and is input into the power supply circuit for storage. Through electric quantity detection and a wireless charging mode, power can be timely supplied, an acquisition function of the apparatus can be guaranteed, and the apparatus has the advantages of high precision and high integration.

Description

technical field [0001] The invention relates to a wireless collection device based on wireless charging, belonging to the technical field of wireless sensor networks.
