Airplane APU working condition monitoring system for airport

Abstract

Provided is an airplane APU working condition monitoring system for an airport. The system comprises an infrared temperature sensor, an image sensor, an electric pan-tilt, a main controller and an Ethernet communication module. The infrared temperature sensor and the image sensor are arranged on the electric pan-tilt. The infrared temperature sensor is connected with the main controller. The image sensor is connected with the main controller. The electric pan-tilt is connected with the main controller connected with the Ethernet communication module through a data bus and an RS-232 interface or an RS-485 interface. The airplane APU working condition monitoring system for the airport has the advantages that first, real-time and automatic monitoring of the working condition of an APU in the process of airplane ground operation can be achieved without installing sensors or communication devices on an airplane; second, the non-contact type detection technology is adopted in the system, so that no influence on the airplane and the ground operation of the airplane is caused; third, the system can automatically adjust the detecting direction to be adapted to the positions of exhaust ports of APUs of different models.

Description

technical field [0001] The invention belongs to the technical field of infrared temperature detection, in particular to an aircraft APU working condition monitoring system used in airports. Background technique [0002] In recent years, the Civil Aviation Administration of China has vigorously advocated energy conservation and emission reduction in the civil aviation industry, and implemented a series of energy conservation and emission reduction research and construction projects, and the bridge-mounted equipment replacement APU project is one of them. The so-called APU is the English abbreviation of aircraft auxiliary power unit (Auxiliary Power Unit), which is a small jet engine with two main functions: one is to provide high-pressure gas to help the main engine of the aircraft to start; the other is to operate on the ground of the aircraft. Or provide electricity and fresh air during flight. In the past, the aircraft could only rely on the APU to provide electricity and...

Problems solved by technology

However, the APU working condition data in the airborne equipment cannot be transmitted to the ground in real time, and due to airworthiness and safety reasons, it is also impossible to install an APU working condition data transmission device in the aircraft
