Cheng Wei：After single-chip microcomputer judges generator commutation filtering transformation by gathering after generator three-phase alternating current rectifying and wave-filtering voltage Vin+
Whether 28V electricity meets the condition to photoelectric nacelle power supply, if meeting condition, single-chip microcomputer opens I level controlling switches, generator
28V electricity enters power supply switch circuit after rectifying and wave-filtering conversion；If there is outside 28V electricity, then powered by outside 28V, otherwise by
28V electricity power supply after generator commutation filtering transformation；
Single-chip microcomputer by judge automatic pilot control load discrete control signal state and load supply voltage signal come
The state of II level controlling switch signals is controlled, the II level controlling switch control signals of single-chip microcomputer are initialized as low level, outside 28V
28V electricity is directly output to photoelectric nacelle power supply after electricity or generator commutation filtering transformation；
When single-chip microcomputer detects that the saltus step of trailing edge occurs in detection voltage of the photoelectric nacelle supply voltage after electric resistance partial pressure
When, II level controlling switch signals are put height by single-chip microcomputer, are set low again after the preset time that is delayed, and power supply exports powers to photoelectric nacelle,
Thereby filter out II level controlling switch signal preset times and put power down power up during height, realize the function of the upper electricity of delay.
Wherein, the preset time is 30s.
Wherein, the load supply voltage signal is powered output valve for the load that is gathered.
(3) beneficial effect
