Automation device for use in civil aircraft environment control system function test

Abstract

The invention relates to an automation device for use in a civil aircraft environment control system function test, which belongs to the technical field of aircraft manufacturing. The automation device comprises an air source processing component, an electric air heating furnace, an air heating furnace controller, a main pipeline system, a pneumatic valve control component, a metal hose component, a wireless sensing communication module, a programmable logic controller (PLC) control module and an upper machine monitoring computer. In the invention, an aircraft pressure cabin and air conditioner pipeline leakage amount test, a cabin pressure regulating system test, a cabin air temperature regulating system function test and an anti-ice system function test are carried out by using an on-spot air source of an aircraft assembly plant in place of an engine or an auxiliary power unit (APU) unit, so that a plurality of test items in the aircraft environment control function test can be completed, and the requirements of aircraft mass production on the quality and efficiency improvement on the environment control function test in a final assembly process are met.

Description

technical field [0001] The invention relates to a device in the technical field of aircraft manufacturing, in particular to an automatic device for functional testing of a civil aircraft environment control system. Background technique [0002] The aircraft environment control system is mainly used to control and adjust the temperature and pressure of the air in the cockpit and the cockpit, limit the temperature and pressure of the air supply in the pipeline to the required limit, and ensure that the cockpit and the cockpit have a certain temperature, pressure, and air quality. Flow rate, humidity and air cleanliness, etc., to meet the necessary conditions for the normal work and life of the crew on board. Aircraft environmental control system is an important part of modern civil aviation aircraft or military combat aircraft. Whether it can work normally is directly related to the flight safety of the aircraft, the safety of the passengers and the comfort of the ride, as wel...

AI Technical Summary

Problems solved by technology

This test system simulates the temperature measurement signal and the voltage signal of the electric valve in the aircraft environmental control system through a multi-channel resistance automatic adjustment device, and tests whether the equipment in the environmental control system can work normally by changing the simulated signal, but this test system cannot Complete the air conditioning pipeline and cockpit leakage test
