Abstract
The invention belongs to the technical field of aviation protection and rescue, and in particular relates to a method for acquiring an ejection deplaning signal of an ejection seat. The method is that a first connecting module (1) is connected with the ejection seat (5); a second connecting module (2) which is matched and connected with the first connecting module (1) is arranged on a plane body. The method is characterized in that the second connecting module (2) is connected with a plane parameter system (3) and a chassis ground (4); when the seat is not ejected, the plane parameter system (3) records a ground signal input by the chassis ground (4); when the seat is ejected and deplaned and upwards move in a certain distance, the first connecting module (1) is separated from the second connecting module (2), the ground signal input by the chassis ground (4) is cut off, and the plane parameter system records an open-circuit signal which is the seat ejecting deplaning signal. With the adoption of the method, the ejection deplaning signal can be acquired during ejecting the seat and can be inputted into the plane parameter system to be recorded in the plane, and therefore, whether the seat is started to be ejected and deplaned in emergency can be known, and strong evidence is provided to determine the working condition of ejecting the seat and analyzing the flying accident.
Description
Technical field
The invention belongs to airway protection lifesaving technology field, more particularly to a kind of ejector seat ejection escape signals collecting
Method.
Background technology
The ejector seat that domestic active service fighter plane is equipped with does not possess the work(of the signal of disembarking that collection seat launches upwards mostly
Can, if in aviation accident, the situation that pilot does not eject cabin occurs, then whether cannot be accurately judged to this situation
Caused by ejector seat does not start ejection escape upwards, therefore can crash analysis and system reliability checking be caused to be stranded greatly very much
Disturb.
Content of the invention
The purpose of the present invention is：Gather ejection escape signal for ejector seat, ejector seat working condition is sentenced
Disconnected and aircraft accident analysis is significant.
The technical scheme is that：
A kind of ejector seat ejection escape signal acquisition method, the system used by this method include the first link block 1,
Two link blocks 2, aircraft FDR system 3, casing ground 4 and ejector seat 5, wherein, the first link block 1 and ejector seat 5
Connect, setting and the second link block 2 of the supporting connection of the first link block 1 on airframe, the second link block 2 with fly
Machine FDR system 3, casing ground 4 connection.
When seat does not normally launch work, aircraft FDR system 3 record is the earth signal inputting from casing ground 4, when
Seat fire disembark upwards motion certain distance when, the first link block 1 is separated with the second link block 2, casing ground 4 input
Earth signal disconnects, FDR system record open circuit signaling, i.e. seat fire is disembarked signal.Interface relationship is shown in Fig. 1.
The invention has the beneficial effects as follows：
The present invention can gather ejection escape signal in the ejector seat course of work, aboard can by this signal input extremely
FDR system is recorded, and can learn under case of emergency, whether seat starts ejection escape, and ejector seat working condition is judged
And aircraft accident analysis provides strong evidence.
Brief description
Fig. 1 is the annexation figure of system for use in carrying of the present invention；
Fig. 2 is the annexation figure of the embodiment of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail：
A kind of ejector seat ejection escape signal acquisition method, the system used by this method include the first link block 1,
Two link blocks 2, aircraft FDR system 3, casing ground 4 and ejector seat 5, wherein, the first link block 1 and ejector seat 5
Connect, setting and the second link block 2 of the supporting connection of the first link block 1 on airframe, the second link block 2 with fly
Machine FDR system 3, casing ground 4 connection.
When seat does not launch, aircraft FDR system 3 record is the earth signal inputting from casing ground 4, works as seat fire
Disembark upwards motion certain distance when, the first link block 1 is separated with the second link block 2, casing ground 4 input earth signals break
Open, FDR system records open circuit signaling, i.e. seat fire is disembarked signal.
This ejection escape signal acquisition method is applied on aircraft ejector seat, is reduction procedure, mitigates system weight
Former ejector seat 5 can be improved design by amount.
First link block 1 adopts supply socket, and the second link block 2 adopts attaching plug.On machine, power supply passes through power supply
The connection of socket and attaching plug enters ejector seat 5.
The chair basin jacking system of ejector seat 5 is connected with the attaching plug on aircraft by supply socket, to enter to seat
Attaching plug, during emergency ejection, is pulled out from supply socket by row power supply by a cable wire being connected with cockpit floor, thus
Power supply on disconnection machine.
As Fig. 2, the attaching plug in the supply socket and aircraft on seat is disposed as 4 cores, according to Fig. 2 wiring side
Method, casing earth signal passes sequentially through the core A on attaching plug, the core E in supply socket, ejector seat, the core in supply socket
Core B on F, attaching plug enters aircraft FDR system.
When seat fire is disembarked, supply socket is separated with attaching plug, and the earth signal of the original record of FDR system disconnects,
It is changed into open circuit signaling, FDR system records this open circuit signaling, as seat fire is disembarked signal.
