Specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the present utility model is elaborated.
As illustrated, this utility model mainly includes step-down rectifier filtration module, burning voltage output module, single-chip microcomputer control Molding block, state indicator module, charge circuit, set of cells and emergency lighting output;
Step-down rectifier filtration module is as shown in Fig. 2 by electric fuse F1, transformator T1, commutation diode D1-D4, filtered electrical Hold C1, middle power tube MJE13003 and corresponding peripheral circuit composition, electric fuse F1 prevents circuit overloads, commutation diode D1- D4 forms rectifier bridge, the AC conversion accessing is unidirectional current, carries out blood pressure lowering using switching mode power supply transformer and peripheral circuit, Use for charge circuit and single chip control module.
Burning voltage output module as shown in figure 3, by every degree diode D7 (IN4007), filter capacitor C7 (0.1uF), C8 (100uF/16V), the three terminal regulator U3 (HT7150) of C9 (0.1uF) and exportable stable precision DC voltage is constituted, purpose It is the DC5V voltage that the DC conversion producing step-down rectifier filtration module is output uses for single-chip microcomputer.
Charge and discharge circuit and emergency circuit as shown in figure 4, charge circuit by the audion Q5 that charges, control audion Q4 and Corresponding peripheral circuit composition, wherein diode D11 has the energy preventing set of cells to pour in down a chimney function, and continuous charging resistor R27 is being filled After the electric time terminates, continue to provide the charging of small current to set of cells.
Discharge circuit is realized being made up of single-chip microcomputer the 3rd foot and Q6,7 and respective peripheral circuit.When external power source disappears or sends out During raw fault, single-chip microcomputer 3 foot exports high level, Q6,7 in succession works, and the energy of energy-storage battery group is passed through Q6 to be provided to rear class.
When set of cells both end voltage with the emergency time prolongation, slowly decline, therefore also set in discharge circuit There is battery discharging voltage detection module, battery tension detection module is connected with single chip control module, that is, when R12 electricity group two When terminal voltage reaches 80% setting value, single-chip microcomputer 3 foot exports low level, and emergency lighting stops.
Emergent part is made up of emergent output triode Q8,9 and corresponding peripheral circuit, and in case of emergency standing alone as should Anxious illumination output power supply.
Single chip control module is made up of as shown in figure 5, dividing integrated circuit U1 (LHYJ0018) and peripheral components, when AC supplies When establishing beginning power supply by cable, single-chip microcomputer intervalometer starts timing, and timing is determined by inside single-chip microcomputer, and this circuit considers emergent photograph It is used nickel-cadmium cell group as energy-storage battery more bright lamp, charged using timing in 16 hours.When being not up to setting time, U1 the 6th foot (P0.5) export high level, charge circuit charges normal;When reaching 16 hours setting values, U1 the 6th foot exports low level, just stops Often charge.
According to the charge characteristic of nickel-cadmium cell group, be provided with small current trickle charge give continuous fill, prevent charge circuit complete Fully closed have no progeny, set of cells is carried out self discharge and is led to the emergency time not reach requirement due to the internal resistance of battery itself.This portion Function R27 in charge circuit is divided to realize.
The whether online detection function of set of cells is made up of single-chip microcomputer 12 foot (P4.2/AIN2) and resistance R12,13 and C13.
