High-speed synchronous acquisition system for images and power data

Abstract

The invention discloses a high-speed synchronous acquisition system for images and power data, which comprises a signal generator, a power sensor acquisition device and two high-speed camera acquisition devices, wherein the power sensor acquisition device comprises a power sensor, a signal conditioning module and a mechanics data collecting and processing computer; a signal is output to the signal adjusting module by the power sensor to be conditioned; then, the conditioned signal is collected, processed and stored by the computer; the first high-speed camera acquisition device is operated in the external triggering mode; the second high-speed camera acquisition device is operated in the edge triggering mode; and the signal generator generates a pulse signal so as to trigger the acquisition action of the power sensor, the first high-speed camera acquisition device and the second high-speed camera acquisition device. According to the structure, the flying gesture and the flying power of insects are simultaneously measured, and the high-speed synchronous acquisition system for image and power data is suitable for the occasions of synchronous analysis of the state and the stress situations of moving objects.

Description

technical field [0001] The invention relates to a high-speed image and force data synchronous acquisition technology, which can be used for the synchronous measurement of the insect's flying attitude and flight force. Background technique [0002] Micro flapping wing aircraft is a new type of aircraft that imitates the flight of birds or insects. Compared with miniature fixed-wing and rotary-wing aircraft, its main feature is that it integrates the functions of lifting, spin-stop and propulsion, and has strong maneuverability. and flexibility. Moreover, because micro-aircraft has the characteristics of small size, light weight, portability, and good concealment, it has extremely broad application prospects in military and civilian applications such as disaster rescue, battlefield detection, and communication relay, and has become a new research topic in the world. hotspot. Due to the small size and low flight speed of the micro-flapping-wing aircraft, flying under the co...

Problems solved by technology

[0003] In Chinese Patent Publication No. CN1765701 "A High-Flying-Frequency Insect Flight Movement Observation Device" and Patent Publication No. CN1765700 "A High-Flying-Flying Insect Flight Parameter Measuring Device", only high-speed camera is used to measure the insect's flight Attitude was photographed, and the lift and thrust of insects in flight cannot be obtained

Although some researchers at home and abroad have measured the lift and thrust of insects during flight, due to technical limitations, the high-speed camera and the mechanical test system cannot be synchronized to collect, and it is difficult to synchronize the flight attitude and flight force for analysis.
