Electronic resume recording device of unmanned aerial vehicle

Abstract

The invention discloses an electronic resume recording device of an unmanned aerial vehicle, which comprises a main control chip, a flight data receiving interface, a clock circuit, a storage unit and a power management chip, wherein the main control chip reads flight data frames through the flight data receiving interface, and extracts a status bit and UTC (universal time coordinated) time in the flight data frames; the flight data frames are added with time stamps output by the clock circuit and output to the flight data region in the storage unit; the status bit is output to the resume use region of the storage unit; the UTC time is output to the clock circuit to carry out time correction on the clock circuit; the status bit is used for identifying the flight operation condition of the unmanned aerial vehicle; and the main control chip periodically queries the power supplying state of the power management chip and outputs the power supplying state to the resume use region of the storage unit. The electronic records such as device working conditions, storage environment, mounted equipment configuration information, flight and task data of the unmanned aerial vehicle are recorded.

Description

technical field [0001] The invention relates to an electronic history recording device for an unmanned aerial vehicle. Background technique [0002] At present, due to the small size of UAVs at home and abroad, or they are in the development stage, they basically rely on paper and manual statistics to complete important historical events (flight time, engine working time, flight sorties, and key equipment usage) that occurred during system use. time). Other types of domestic aircraft (such as civil aviation aircraft) are mainly installed with certain functional counters (similar to odometers), but manual recording and statistics are required to reflect the data. For flight records, independent black boxes are used to sort them out, which is not an automated operation. [0003] At the same time, the existing resume recording equipment or methods also have the following limitations: [0004] (1) The current domestic method is to complete the records by using text records and...

AI Technical Summary

Problems solved by technology

[0004] (1) The current domestic method is to complete the records by using text records and manually inputting them into the information center, but such records often depend on the record mechanism, and users cannot directly obtain the flight number and time of the aircraft through technical means , The power-on time and engine working time of key components with life, the direct consequence is that the aircraft loses normal maintenance;

[0005] (2) In addition, the flight data records only rely on the ground station records, and the airborne recorder is only optional due to functional limitations, and the arrangement of these records requires full-time personnel to manually carry out repetitive arrangements;

[0006] (3) The environmental factors (temperature, humidity, air pressure, vibration) experienced by the real aircraft lack normalized recording means when the aircraft is not powered on, and these data are accumulated as the use data of the whole life cycle and the entire aircraft Important basis for health assessment
