Severe visual environment unmanned aerial vehicle detection system and detection method thereof based on ultrasonic waves

Abstract

The invention provides a severe visual environment unmanned aerial vehicle detection system based on ultrasonic waves. The system comprises an airborne detection system, an unmanned aerial vehicle anda ground station. The airborne detection system comprises a base, a control unit, a power supply module, a vertical shaft motor module, a first connecting arm, a transverse shaft motor module, a second connecting arm and an ultrasonic wave ranging module. The invention further discloses a detection method of the severe visual environment unmanned aerial vehicle detection system based on the ultrasonic waves. The unmanned aerial vehicle in the air is adopted for carrying out complex terrain measurement, and the method has great advantages for severe visual environments such as dense smoke andfoggy environments. The unmanned aerial vehicle is adopted for detection and data receiving and transmitting, measurement efficiency is high, operation is convenient, and reliability is high.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement, and in particular relates to an ultrasonic-based unmanned aerial vehicle detection system in harsh visual environments and a detection method thereof. Background technique [0002] The acquisition of environmental terrain data is of great significance to firefighting operations, disaster rescue, industrial construction, national defense and military and other fields. At present, measuring equipment based on photoelectric sensors, infrared sensors, ultrasonic sensors, etc. are often used for short and medium distance measurement and environmental terrain detection. However, photoelectric sensors and infrared sensors will be greatly disturbed or even unusable under harsh visual conditions, such as dense smoke, fog, fire, etc. If the ambient temperature is high, the infrared sensor equipment will fail. Therefore, the above-mentioned techniques are limited by the environment. In con...
