Often monitored state, and show combustion gas tolerance value.Buzzer warning sound can be closed by button, method be in 10s continuously by by
Key 5 times.
4. temperature alarming: when temperature over-range having been detected, can be switched to temperature over-range report from tolerance display state immediately
Alert state.If there occurs leakage alarm the most simultaneously, then will not report to the police by displays temperature, because leakage alarm priority ratio temperature report
Alert higher.Now backlight can become red, and buzzer can pipe, the channel number that middle digital section meeting displays temperature transfinites,
Wherein first character is " H ", and second character is channel number.
If now there being multiple passage to be detected simultaneously by temperature over-range signal, then it is all logical that middle channel number can circulate display
Road, about 5s clock one channel number of switching.
In alarm procedure, if temperature over-range blackout, product of the present invention can automatically restore to normal monitoring state, and show
Show combustion gas tolerance value.
Buzzer warning sound can be closed by button, and method is continuously by button 5 times in 10s.
5. fuel mode switching: fuel mode switching push button can trigger alarm switching channel persistently export high level or
Low level signal, often presses the most changeable output state of button next time, thus switches the fuel mode of automobile, and initial output value can
Pass through software arrangements.
Finally illustrating, above example is only in order to illustrate technical scheme and unrestricted, although with reference to relatively
The present invention has been described in detail by good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, and without deviating from objective and the scope of the technical program, it all should be contained in the present invention
Protection domain in the middle of.
