Abstract

The invention provides a photoelectric health parameter detector based on an audio interface, including an audio interface, a power supply resonant circuit, a receiving resonant circuit, a signal receiving circuit, an energy storage circuit, an electronic switch circuit, a single-chip microcomputer, a voltage regulation circuit, and an H-bridge circuit , infrared light-emitting diode, red light-emitting diode, photodiode and operational amplifier circuit; the signal receiving circuit is used to convert the resonant waveform signal output by the receiving resonant circuit into a square wave pulse signal recognized by the single-chip microcomputer; The control signal sent by the H-bridge power supply control signal output terminal changes the output voltage value of the controllable voltage output terminal of the voltage regulation circuit; the operational amplifier circuit is used to amplify the acquisition signal sent by the signal output terminal of the photodiode. The detector has a low bit error rate, high universality, and does not need its own power supply, so it has a high market application prospect.

Description

technical field [0001] The invention relates to a photoelectric health parameter detector, in particular to a photoelectric health parameter detector based on an audio port. Background technique [0002] With the advancement of economy and technology, smart mobile terminal devices such as mobile phones, PDA devices, and tablet computers are more and more closely related to people's lives. At the same time, its performance and functions are getting stronger and stronger. There are more and more peripheral devices and applications related to it. On the one hand, these peripheral devices need to communicate with smart mobile terminals. On the other hand, for some low-power devices, it is also hoped that the power supply can be taken into account to avoid the loss and cost increase caused by the need for external batteries. The current communication methods of peripheral devices and mobile terminals mainly include the following methods: 1) Wireless communication, mainly using ...
