Title:
ON-BOARD MONITORING SYSTEM FOR TETHERED UNMANNED AERIAL VEHICLE, AND MONITORING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/164286
Kind Code:
A1
Abstract:
An on-board monitoring system for a tethered unmanned aerial vehicle, the system comprising a voltage detection unit (30), a temperature detection unit (20) and a main control chip (10). The temperature detection unit (20) comprises a differential input module for isolating a temperature signal collected by a temperature sensor of a tethered unmanned aerial vehicle; and a first expansion chip for converting the isolated temperature signal into a voltage signal and inputting same into the main control chip (10). The voltage detection unit (30) comprises a first operational amplifier for amplifying a voltage signal of a device power supply of the tethered unmanned aerial vehicle; an optical isolation amplifier for isolating and amplifying a voltage signal of a Synqor power supply of the tethered unmanned aerial vehicle, a voltage signal of a backup battery and an output voltage signal of a UPS; a second operational amplifier for amplifying a voltage signal output by the optical isolation amplifier; and a second expansion chip for performing differential processing on the voltage amplified by the first operational amplifier and the second operational amplifier, and inputting a processing result into the main control chip (10). The system can improve the monitoring accuracy of a monitoring system. Further provided is an on-board monitoring method for a tethered unmanned aerial vehicle.
