The accompanying drawing explanation
Fig. 1 is the circuit function block diagram
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, the AC-DC conversion circuit is from utility grid voltage (as AC220V), being transformed to direct voltage (as DC24V).This conversion process comprises following circuit: exchange input, EMC circuit, input rectifying filter circuit; PWM controller, current limliting, pressure limiting, power inverter, output rectifier and filter, direct current output (Voltage-output that comprises charging circuit); the voltage stabilizing loop, overvoltage crowbar etc.
Standby battery circuit is in main when work electricity, and standby battery is in dormant state, and the AC-DC circuit is the battery charging, when battery approaches while being full of, adopts constant current charging mode, when approaching while being full of the pressure limiting low current charge pattern that adopts.
Voltage monitoring: by main electric sample circuit, AC-input voltage is monitored, " main electricity work " lamp and " charged state " lamp when AC voltage is normal on main panel are lighted.When the AC lower voltage is main electric alarm magnitude of voltage, " control and processing unit " will export under-voltage index signal and send into respectively panel and light " main electricity is under-voltage " lamp, and connection is without source contact " ZQY ", the warning of simultaneously sounding.When Attended mode, can eliminate sound interference by clicking " noise reduction " button.When AC voltage continues to be reduced to conversion and control point, power supply is transformed into standby electricity output by main electricity output, and " main electricity work " and " charged state " lamp on main panel extinguish, and connects without source contact " ZT ", and " standby electricity work " lamp is lighted.If noise reduction, the warning of again sounding, still can noise reduction.When standby electricity work lower voltage arrives standby electric under-voltage set point, " standby electricity the is under-voltage " lamp on main panel is also lighted, and connects without source contact " BQY ", and the warning of sounding, also can noise reduction.When standby piezoelectric voltage continues to be reduced to standby electric shutoff voltage, cut off standby electricity output, send the audible alarm of being longer than one hour simultaneously, the prompting user must be processed.Now all indicator lights extinguish entirely.If now main electricity recovers normal, report to the police and stop.Get back to main electricity work and charged state, " main electricity work " and " charged state " lamp are lighted, and other lamp extinguishes, in order to stand-by.
When standby electric when in running order, if main electricity recovers normal, be transformed into main electricity work and charged state, " main electricity work " and " charged state " lamp are lighted.
No matter from main electricity, be transformed into standby electricity work, or be transformed into main electricity work by standby electricity, at output, all no-voltage drops into any interval of 0, has remained output voltage.
Only have main electricity, not standby electricity, or standby electric power line connects instead, under the situations such as standby electric incoming end short circuit, all puts electric fault on record, except " main electricity work ", lamp is bright, " for electric fault " lamp is also lighted, while audible alarm, but noise reduction.Without source contact " BT ", connect.
The utility model is based on that the circuit theory of practical application set forth.For the technical staff in fire-fighting power supply field, according to the utility model scheme, the power supply control technology of developing by same thinking, be all protection range of the present utility model.
