Embodiment 1

[0088] Such as figure 2 As shown, the air-conditioning flow control valve state monitoring device of the present embodiment includes DFDAU, printer, MCDU, ACARS and ground engineering monitoring module; the airborne printing equipment and MCDU are connected to DFDAU respectively, and DFDAU is connected to the ground engineering monitoring module through ACARS. To achieve mutual communication. ACARS is mainly composed of the airborne ACARS CMU, the airline gateway deployed on the ground, and the ground-air data communication network between them. DFDAU is connected to ACARS CMU, while the ground engineering monitoring module is connected to the gateway.

[0089] This embodiment is mainly based on the inherent supporting equipment of these aircraft, and expands the functions of these devices through software design, thereby providing a FCV state monitoring device with good versatility, low cost, and real-time monitoring triggered by fault alarms. The improvement of this embodi...

Embodiment 2

[0194] Embodiment 2 of the present invention provides a method for monitoring the state of an air-conditioning flow control valve. The content of the method is reflected in the above-mentioned device and will not be repeated here.

Abstract

The invention discloses a civil aircraft conditioner flow control valve state monitoring device and method. The method and device are based on a DFDAU, an ACARS and a ground engineering monitoring module. An event trigger logic used for monitoring FCV states is additionally arranged in an ACMS, a format of a FCV message containing FCV state parameters is customized, when FCV overhead non-command is turned off, the event trigger logic triggers to generate the FCV message, the message is printed through vehicle-mounted printing equipment, and/or displayed through a MCDU, and/or transmitted to the ground engineering monitoring module in real time through the ACARS, so that ground maintenance personnel and / or aircrews are informed with the states of FCV timely, a monitoring mechanism that real-time monitoring is triggered by failure alarming is formed, pressure of the aircrews is relieved, the aircrews do not need to pay attention to the passenger cabin height of the aircraft to understand the supercharging situation of the aircraft all the time, but actively warn the ground maintenance personnel and/or the aircrews of potential emergency states, and thus advantageous conditions areprovided for ensuring flight safety.

Description

technical field [0001] The invention relates to the civil aviation transportation industry, in particular to the field of state monitoring of civil aviation aircraft systems and the field of civil aviation maintenance engineering. Background technique [0002] Since the civil aviation aircraft using the new electronic flow control valve EFCV of electro-pneumatic type has been put into operation, there have been many air-conditioning dual-component flow control valve non-command shutdown failures in the air, especially in subtropical high-temperature and humid areas. more frequently. Air-conditioning single-component flow control valves have more frequent failures of mid-air uncommanded shutdown. The modified parts of the old air-controlled pneumatic flow control valve FCSOV and the new EFCV electronically controlled pneumatic type have also experienced non-command shut-off failures in the air of the air-conditioning flow control valve. [0003] figure 1 It is a schematic ...
