Abstract
The invention belongs to civil aviation passenger's emergency oxygen supply control technologies, and in particular to a kind of civil aircraft emergency oxygen supply control method.Civil aviation passenger emergency oxygen supply control technology mainly uses continuous oxygen-supplying technology at present, since using continuous oxygen supply, oxygen unnecessary consumption flow is big.Present invention employs pulse oxygen supply controllers comprising integrated respiratory cavity solenoid valve, breath pressure sensor and high stress sensor on circuit boards, and control is powered to the latch structure for launching mask；When the pressure of high stress sensor reaches emergency threshold value or when receiving the emergency instruction of host computer, pulse oxygen supply controller controls latch structure and launches mask, whether the data of real-time judge mask internal respiration pressure sensor reach oxygen supply threshold value later, whenever reaching oxygen supply threshold value, starting gas source, which is supplied and passes through respiratory cavity solenoid valve, to be supplied oxygen.Controller realizes the accurate control of supply amount of oxygen with impulse form control solenoid valve supply oxygen conveying opportunity and conveying capacity.

Method is used for pulse oxygen supply controller.
Background technique
Currently, civil aviation passenger's emergency oxygen supply control technology mainly uses continuous oxygen-supplying technology, it is mainly characterized by not
It is influenced by the pulmonary ventilation capacity and respiratory rate of user, it is continuous to supply certain flow oxygen.This kind supplies oxygen lacking for control technology
Putting is：Since using continuous oxygen supply, oxygen unnecessary consumption flow is big.
Summary of the invention
The technical problem to be solved by the present invention is to：A kind of more cost-effective oxygen supplying control method is proposed, to meet the people
With the requirement of air passenger emergency life support.
The technical scheme is that：A kind of civil aircraft emergency oxygen supply control method uses pulse oxygen supply controller, packet
Integrated respiratory cavity solenoid valve, breath pressure sensor and high stress sensor on circuit boards is included, and to dispensing mask
Latch structure is powered control；When the pressure of high stress sensor reaches emergency threshold value or receive the emergency of host computer
When instruction, pulse oxygen supply controller controls latch structure and launches mask, later real-time judge mask internal respiration pressure sensor
Whether data reach oxygen supply threshold value, and whenever reaching oxygen supply threshold value, starting gas source, which is supplied and passes through respiratory cavity solenoid valve, to be supplied oxygen.
Different cabin pressures has corresponding single oxygen-supplying amount, is sensed according to the respiratory pressure of respiratory cavity solenoid valve front end
Device signal controls the on-off of solenoid valve.
The pulse oxygen supply controller further includes the temperature and pressure transmitter of gas source, is modified to pulse oxygen supply amount.
The pulse oxygen supply controller further includes that lamp, breathing current indicator lamp are shown in self-test.
The pulse oxygen supply controller externally controls the power supply of latch structure by host supplying power.
When host power supply is connected, pulse oxygen supply controller opens self-checking function, and self-test indicator light shows self-detection result.
The beneficial effects of the invention are as follows：Mask cavity pressure and cabin pressure are acquired, controller controls electromagnetism with impulse form
Valve supplies oxygen conveying opportunity and conveying capacity.Meanwhile the controller has the function of that stream function is shown in internal element self-test and instruction, oxygen
The accurate control function of amount of oxygen is supplied in pulse under energy, different height.
Detailed description of the invention
