Reasonable movement is made in different sections.In particular, human body is in In danger under state, monitoring method and system setting are held
The continuous time can guarantee infrequently to trigger alarm signal.
For the first concentration threshold A < carbonomonoxide concentration value concentration threshold B of C < second, and the duration not up to provides
The case where time, system can not execute movement, namely not sound an alarm.
System can by the way that alarm device is arranged, flashed, given a warning by warning lamp etc. in a manner of carry out alarm.It is issuing
When alarm, for passenger, it can be reminded to wear oxygen mask；For driver, it can be reminded to wear oxygen mask, and aircraft is declined
Emergency ventilation etc. is opened to safe altitude.The carbonomonoxide concentration of test can be shown by display.
When cockpit or air supply pipeline are in state In danger, namely " the first concentration threshold A < carbonomonoxide concentration value C < the
When two concentration threshold B ", according to different the first concentration threshold A and the second concentration threshold B is arranged, accordingly, it is specified that the time is optional

It is used in this regard, the first concentration threshold A used by aircraft cockpit is also preferably set greater than air supply pipeline by the present invention
The first concentration threshold A, and aircraft cockpit use the second concentration threshold B be greater than air supply pipeline use the second concentration threshold B,
To set requirements at the higher level to air supply pipeline, the carbonomonoxide concentration that may occur to avoid regional area is exceeded and can not be detected
The case where measuring.For example, being directed to cockpit, the corresponding first concentration threshold A value 9ppm of the first concentration sensor, the second concentration threshold
Value B value 50ppm.And it is directed to air supply pipeline, the corresponding concentration threshold value of the second internal concentration sensor is set smaller,
Such as first concentration threshold A value 7ppm, the second concentration threshold B value 25ppm.
In a preferred embodiment, for different cockpits, respective concentration sensor is also provided with different dense
Spend threshold value, specifically, can by aircraft cockpit cockpit and main cabin, the second concentration threshold used by the main cabin in aircraft cockpit
Value B is set greater than the second concentration threshold B used by cockpit.For example, the first concentration threshold A that cockpit uses can be set as
9ppm, the second concentration threshold B are 40ppm；The first concentration threshold A that main cabin uses can be set as 9ppm, and the second concentration threshold B is
50ppm.Can still have to determine that the driver of whole passenger life limits the air more sternly required from alarm threshold with this
When gap, i.e., system for prompting adjusts carbonomonoxide concentration, guarantees that driver is adapted to higher working strength.
