Specific embodiment
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment
This utility model system is based primarily upon emergency hatch control mode of today, by install additional thereon for prevention by
The system that slide caused by carelessness launches, reaches and warns the purpose attempting to open emergency hatch under non-fortuitous event.
This utility model system principle is：Hatch door handle sensing when handss are near safety door handle, near handle
Device (sensors of capacitance sensor or infrared heat sensor or other similar functions) produces signal and is delivered to signal processing
Unit；When safety pin is pulled out, safe door condition sensor produces signal and is delivered to signal processing unit.Signal processing
Unit detect any of the above-described sensor be triggered after produced signal value, and calculate this signal value, if this signal value is with advance
Storage or the signal value setting are consistent, then judge that this sensor is triggered, output signal drive the speaker simultaneously, and speaker shakes
Move and give a warning sound thus reminding crew.
The structure of the system is as shown in figure 1, mainly include then triggering generation for handss has been detected near safety door handle
The hatch door grip sensor of signal, it is pulled out, for safety pin is detected, the safe door state sensing that then triggering produces signal
Device, for judging that hatch door grip sensor or safe door condition sensor are triggered, send the signal processing list of alarm signal
Unit, for receive alarm signal then send warning speaker and for provide a system to the power supply of electric energy, DC-DC circuit,
Dual-colored LED display lamp.
Wherein, as shown in Figure 2 and Figure 3, power supply adopts battery, this battery and signal processing unit (being arranged on circuit board)
It is arranged in same housing and collectively constitute control module.I.e. controller module is made up of housing, battery, circuit board.Speaker by
Exciter panel and excitation frame composition.Control module pass through cable respectively with hatch door grip sensor, safe door condition sensor and
Speaker connects.This controller module can accept hatch door grip sensor and the signal of safe door condition sensor transmission, and will
It passes to speaker, to send alarm thus reminding crew member after integrating.
Housing can accommodate battery and circuit board, simultaneously the conspicuous position on housing, installs double-colored LED light.When
When battery electric quantity is higher than 40% and all the sensors (hatch door grip sensor and safe door condition sensor) fault-free, LED
For green.When battery electric quantity, less than 40% or hatch door grip sensor breaks down or safe door condition sensor breaks down
When, LED is redness.

The core cell of signal processor is the single-chip microcomputer of low-power consumption, and the advantage of single-chip microcomputer is signal transmission time is millisecond
Level, non-stop run in 24 hours, energy consumption is ultralow；Therefore the time that sensor is triggered between speaker vibrations sounding is less than 0.5
Second, in machine, staff can prevent in time after hearing chimes of doom and attempt to open emergency hatch due under non-fortuitous event
Behavior, thus avoid flight delay and economic loss.
Hatch door grip sensor adopts capacitance sensor or infrared heat sensor, is installed on the interior of emergency hatch trim panel
Side.When handss are near safety door handle, hatch door grip sensor produces signal and is transferred to control module.
Safe door condition sensor is the reed switch of electro permanent magnetic, and it is arranged at the safety pin of safety door.Work as safety
When latch is in normal position, this switch connection, safe door condition sensor does not produce signal；When safety pin is pulled out,
This switches off, and safe door condition sensor produces signal and passes to control module.
Exciter panel and exciter frame constitute the speaker reported to the police, and this speaker is installed on emergency hatch surface, utilize
There is sound with the vibration of safety door into cabin in speaker.
Fig. 4～Fig. 8 is particular circuit configurations figure, and wherein Fig. 4 is DC-DC circuit, and the system accesses pcb board by set of cells
Upper socket J2, electric energy enters DC-DC chip U4 after electric fuse F2 and wave filter F1, and U4 stably exports 3.3V voltage and provides
To system unit.Q1 is battery reverse connecting protection device.
Fig. 5 is signal processing unit, and core adopts single-chip microcomputer as central processing unit, embeds and can write logic control
Software.The major responsibility of signal processing unit is that the state monitoring two external sensors is sent out deciding whether drive the speaker
Sound, and point out plant maintenance personnel by controlling indicator light colors after monitoring battery capacity.
Fig. 6 is the circuit for connecting two sensors, by the signal transmission of two sensors to signal processing unit.
Fig. 7 is loudspeaker driving circuit, the alarm signal being sent according to signal processing unit, and drive the speaker is reported to the police.
Following protection can be accomplished by the system：Reduce the inconvenience bothered and bring to passenger；Improve aircraft
Security performance；Save the huge maintenance cost caused by slide surprisingly launches；Effectively lift the reliability of flight dispatching.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model it should refer to
Go out, all any modification, equivalent and improvement made within spirit of the present utility model and principle etc., all should comprise
