Method and system for video recording

Abstract

The invention discloses a video recording method and system. The method is applied to video monitoring equipment. The video monitoring equipment includes: a main control module, a power supply module and a video monitoring module. The acceleration value in the direction; collect the real-time acceleration value of the aircraft to be monitored in the set direction according to the preset acquisition frequency; judge the video surveillance according to the preset overload threshold and the collected acceleration value of the aircraft to be monitored in the set direction Whether the module satisfies the starting conditions; when the video monitoring module meets the starting conditions, control the opening of the video monitoring module for video recording; and send the recorded video to the data acquisition computer. The technical solutions of the embodiments of the present invention can realize flexible monitoring of various positions on the aircraft, and can use a more intuitive video monitoring method to comprehensively investigate the causes of failures.

Description

technical field [0001] The present invention relates to the field of aerospace technology, and more specifically, relates to a video recording method and system. Background technique [0002] Due to complex structures and functions, high cost, and high safety requirements of aircraft such as rockets and airplanes, it is necessary to conduct various ground tests and flight tests on the aircraft in advance during the development of the aircraft to ensure the performance and performance of the aircraft when it is officially used. quality. [0003] At present, the specific process of ground test and flight test in the prior art is as follows: first establish a test environment on the ground, and then complete the test of a single system and the cross-linking test between multiple systems in order in this test environment, so as to realize the test of a single system. The function verification of the system integrated with multiple systems is completed, and the ground test is co...

Problems solved by technology

In this process, there are the following problems: because the existing video surveillance system is only installed in the main position of the aircraft, the existing flight test can only monitor the working status of a specific position of the aircraft, and the monitoring of the position on the aircraft is not flexible. The working status of other positions on the aircraft cannot be monitored as required

In addition, since the existing flight test can only monitor the working status of a specific position of the aircraft, once the aircraft fails during the flight test, the existing flight test method cannot use a more intuitive video monitoring method to conduct a comprehensive investigation of the cause of the failure
