Control device of ground test of cabin pressure regulator

Abstract

The invention belongs to the technical field of electrical control devices and provides a control device of a ground test of a cabin pressure regulator. The control device comprises an electrical control cabinet, a cabin inner simulation tank body, a cabin outer simulation tank body, a vacuumizing motor and a differential pressure sensor. The cabin inner simulation tank body, the cabin outer simulation tank body and the vacuumizing motor are installed be not far from the electrical control cabinet. According to the invention, through touch screen parameter setting, disadvantages in use of a knob for speed adjustment in the prior art are overcome; convenient and flexible digital input speed adjustment is achieved; the indirect display mode of a simulation meter is changed, so digital acquisition and processing is achieved, direct data display and observation is achieved and reliability and precision of test results are improved; by use of the automation technology and simple devices, the tedious and inconvenient modes of manual recording and storage of data are changed; and the control device is characterized by high automation degree, high stability, simple operation and high applicability.

Description

technical field [0001] The invention belongs to the technical field of electrical control devices, and in particular relates to a ground test control device for a cabin pressure regulator. Background technique [0002] The cockpit pressure regulator is an important part of the aircraft environmental control system. It is widely used in various aircrafts at home and abroad. Ensure aircraft flight and passenger safety. The ground test of the cockpit pressure regulator is used to test whether the basic performance of the cockpit pressure regulator meets the requirements in the ground state, and whether it meets the basic flight requirements. Therefore, the accuracy of the test results affects the normal operation and flight safety of the various systems of the aircraft. It is a production test and Indispensable and important part of the testing process. With the rapid development of modern aeronautical technology, the replacement speed of each airborne product of the aircraft...

AI Technical Summary

Problems solved by technology

[0003] At present, there are control devices for the ground test of the cockpit pressure regulator: 1. The flight height is adjusted by the manual knob, the parameter adjustment is inflexible, and the input error is relatively large; The accuracy of data acquisition is low, which leads to unreliable test results; 3. In the test process, manual data is usually recorded, and the functions of automatic recording, storage and printing of data cannot be realized, and the processing efficiency of test results is low

4. Most of the traditional Russian-made test equipment is used, and the input and output of the control mostly adopt analog and discrete control, lacking automatic test methods

At the same time, the existing control device still has a series of problems such as inconvenient operation, low degree of automation, and high failure rate.
