Diode realizes.
Warning signal output circuit is used for realizing control panel and embedded microprocessor and aircraft light warning system
Crosslinking control.
Concrete operation method of the present utility model and operation principle are as described below.
(1) connection of equipment is carried out.
In the case of aircraft does not powers on, first connect three test cables on control panel, wherein power supply electricity
Cable ground plane 220V alternating current power supply, warning signal cable is connected with aircraft alarm computer plug, and ground wire cable connects.
Now, the initial position of each switch on control panel is set, particularly as follows:
1) ac power switch is placed in the next " off " position.
2) DC power supply switch is placed in the next " off " position.
3) manauto state selecting switch is placed in required state position.
4) individual event-multinomial permutator that automatically selects is placed in required state position under automatic detection state.
5) in addition to direct current warning signal switch is initially set to bottom, remaining signaling switch is in neutral cut-off signal position
Put.
(2) inspection of manual mode
1) power supply is powered inspection
Confirming that cable connects can power on to aircraft rearward, this opportunity answers no signal lamp to ignite in upper each signal lights box, will
Manauto state selecting switch is placed in manual position；Connect ac power switch, then connect DC power supply switch, chain of command
Digital voltmeter on plate should indicate 28V ± 1V voltage, and the most red power supply indicator, green manual ringing lamp should ignite, this
Time, on explanation machine, 28V voltage and the output of 5V voltage are normal.
2) Non-follow control status checkout
Manually detection uses the mode being artificially switched on or switched off triggering signal to complete input or the stopping of signal, by design inspection
Ranging sequence and each permutator of alarm level can control the input of two paths of signals, and neutral position is open position, alerts defeated
Enter signal to be controlled respectively by 39 control switches respectively, be examined in the response of circuit warning signal, from Level 1Alarming, two grades of announcements
Alert, three grades of alarms, level Four alarm, Pyatyi alarm, configuration alarms check step by step；Often connecting can after a warning signal shows normally
Disconnected, then carried out the operation of next warning signal.Owing to direct current warning signal is that ground ON signal is effective, this switch is arranged
For upper and lower two-position switch, input ground ON signal, input grounding signal time the next time upper.
After power module is working properly, manual ringing lamp 10 ignites；28V DC voltage one tunnel exports hand control switch
Part, is added to required triggering switch by+28V voltage signal, and another road is added to DC/DC modular converter, by+28V voltage transformation
For+5V voltage ,+5V voltage signal is added to required triggering switch the most again；In circuit, the diode of series connection has been used for isolation
The manual effect with automatic partial circuit, uses 1N4007 diode-isolated ,+5V branch road and ground wire branch road to use at+28V branch road
1N4148 diode-isolated.Earth terminal is connected with aircraft body by ground wire cable, makes assay device negative wire and aircraft
Body isoelectric level, meanwhile, is added to required triggering switch, it is achieved manual operation detection functional check by ground signalling.
Under Non-follow control state, operate alarm signalman on control panel and control the warning signal corresponding announcement of switch output in district
Alert signal, if pulling a certain warning signal position, if warning light corresponding in passenger cabin does not works, then illustrates this alarm
There is fault in signal branch.
When manual operation, it is also possible to be simultaneously entered multichannel warning signal.Manually detection is complete, direct current warning signal is opened
Pass is placed in bottom, and remaining all warning signal controls switch and is placed in neutral position.
(3) automatic control state inspection
In this case, individual event test and two kinds of method of testings of multinomial test can be divided into.If midway needs to interrupt detection,
The pressing the most reconfigurable detection mode of SR.
