The receiving module includes: the second optocoupler U4, the 5th resistance R233, the 6th resistance R234, zener diode D17；
The rectification circuit includes rectifier bridge；
The first port of the first optocoupler U5 connects supply voltage VCC_MCU, and second port is connected by 3rd resistor R218
Incoming level DAL I_TX, third port connect the first end of first resistor R220, and the 4th port is separately connected first capacitor C11
Anode, first diode D13 cathode；
The second end of the first resistor R220 is separately connected the base of the first end of second resistance R221, the first triode Q206
The second end of pole, second resistance R221 connects the cathode of first capacitor C11, the emitter of the first triode Q206, two pole of pressure stabilizing
The anode of pipe D17；The collector of first triode Q206 connects the first end of the 4th resistance R222；The second of 4th resistance R222
End is separately connected the third port of the anode of first diode D13, the second end of the 5th resistance R233, rectifier bridge D9；
The first port of the second optocoupler U4 connects the first end of the 5th resistance R233, and second port connects zener diode
The cathode of D17, third port connect the first end of the 6th resistance R234, while meeting DAL I_RX, and the 4th port meets VCC_MCU；The
The second port of six resistance R234 is grounded；Level translation process includes: when DAL I_TX is low level, and the first light of cooperation is even
The sending module of U5 accesses DAL I bus, meets DAL I electrical standard to low level requirement；When DAL I_TX high level
When, the sending module of the first light idol U5 of cooperation accesses DAL I bus, meet requirement of the DAL I electrical standard to high level, the
One resistance R220 and the first triode Q206 ensures that the static current of lcd in DAL I bus is no more than 250MA, while the one or three pole
The parameter selection of pipe Q206 requires DC gain to be greater than 100db, while being the first triode Q206 heat dissipation by heat-sink unit；
The receiving module triggers DAL I_RX low level in bus low level, and triggering DAL I_RX high is electric when bus high level
Flat, zener diode D17 guarantees that bus guarantees the second light in the minimum high level voltage that not up to DAL I electrical standard requires
Coupling U4 is not driven.
