Embodiment Construction

[0025] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

[0026] Such as figure 1 As shown, the alarm system for implementing the present invention may include a central alarm computer 1 , a cargo hold pressure regulation controller 2 , a first cargo hold pressure sensor 3 and a second cargo hold pressure sensor 4 .

[0027] Both the first cargo hold pressure sensor 3 and the second cargo hold pressure sensor 4 are used to detect the height information of the cargo hold, and / or determine whether the hold exceeds a predetermined height warning value. The first cargo hold pressure sensor 3 is connected to the central alarm computer 1 by a hard line; there is usually a second cargo hold pressure sensor 4 inside the cargo hold p...

Abstract

The invention relates to a pressure regulating system of an aircraft compartment, in particular to a height warning method of a cargo compartment of a cargo transport aircraft, and aims to solve the problem that a conventional aircraft height warning method cannot meet warning demands of a cargo transport aircraft. The height warning method comprises the following steps: a first cargo-compartment pressure sensor transmits corresponding warning information to a central warning computer; a cargo-compartment pressure regulating controller transmits the corresponding warning information; the central warning computer performs appropriate selection according to the warning information transmitted by the first cargo-compartment pressure sensor and the warning information transmitted by the cargo-compartment pressure regulating controller. The height warning method of a cargo compartment of a cargo transport aircraft, disclosed by the invention, realizes multistage height warning for the cargo compartment of the cargo transport aircraft; under the pressure relief of the cargo compartment, hint-stage compartment height warning is sent out, so that the operation of a pilot is not disturbed; besides, in the height warning method of a cargo compartment of a cargo transport aircraft, disclosed by the invention, judgment is performed according to the detection information of the first cargo-compartment pressure sensor and the detection information of a second cargo-compartment pressure sensor simultaneously, so that the height warning method has the characteristic of redundancy.

Description

technical field [0001] The invention relates to an aircraft cockpit pressure regulating system, in particular to an alarm method for cargo cabin height of a cargo aircraft. Background technique [0002] At present, the altitude warning levels of aircraft are all warning levels. For cargo aircraft, the cargo compartment depressurization is a typical configuration of transport aircraft. A warning-level warning is issued, but it is normal for the cargo compartment to be too high at this time, and a high-level warning should not be issued to affect the pilot's operation. At the same time, the aircraft altitude warning is very important to the safety of the pilot and the aircraft. Therefore, the cockpit altitude warning of the cargo aircraft needs a multi-level and redundant warning method. The current warning method cannot meet the warning requirements of the transport aircraft. Contents of the invention [0003] The purpose of the present invention is to provide a method for...
