Individual crystal triode B 5 base stage making connection gate circuit B 8 is high level, is connected to continuing on crystal triode B 6 colelctor electrode
The J5 contact of electrical equipment B 7 is in normally open, the J6 contact conducting with relay B 7, connects the crystal triode of gate circuit A 3
A 5 base stage is high level, and crystal triode A 5 is in saturation, is connected to the J2 of crystal triode A colelctor electrode relay A
Contact is in normally open, the J3 contact conducting with relay A, and so no matter adjustable square-wave oscillator output makes connection gate circuit
The crystal triode A base stage of A is low level or high level, and crystal triode A is still within saturation, is connected to transistor
The J2 contact of A colelctor electrode relay A is in normally open, is connected to the J3 of relay A, and the J6 contact of relay A obtains positive electricity
Source, due to the J6 contact portion gate circuit C of relay A, gate circuit D, microprocessor, data output device positive power source terminal, door electricity
Road C, gate circuit D, microprocessor, data output device switch on power, and work all the time.Microprocessor is by water level B3, toxic gas
The conventional alert of any one (three-level monitoring) in C3, toxic and harmful D3 exports conventional alert by data output device
Data, enters sleep state.When alert is upgraded to early warning alert further, i.e. water level B2, toxic gas C2, toxic and harmful
Any one in D2 triggers the interruption of microprocessor 12 by gate circuit D, and microprocessor 12 enters working condition, by I/
O4, I/O5, I/O6 identify that alert, export warning data by data output device 13.Post a cordon in advance when alert reaches
When, that is, water level B1, any one in toxic gas C1, toxic and harmful D1 are triggered in microprocessor by gate circuit D
Disconnected, microprocessor, that alert is identified by I/O1, I/O2, I/O3, alert data is exported by data output device.
Until water level B3, toxic gas C3, toxic and harmful D3 alert signal relief, just recover such as front.
