Whole LED emergency-lighting system mainly contains 3 kinds of operating states, and its course of work is as follows:
When the alternating voltage normal power supply, enter battery charging state.The Charger Cutoff control signal of STM8S003K microprocessor output is high level, Charger Cutoff control signal exports battery charger to, make battery charger closed, the AC/DC Switching Power Supply is converted to direct voltage with alternating voltage, then by battery charger battery 8 is charged.The Main Driver Cutoff control signal of STM8S003K microprocessor output is high level, and control AC/DC master constant-current source is started working, so that described main LED lamp is lighted.The Stdby Driver Cutoff control signal of STM8S003K microprocessor output is high level, and control AC/DC starts working from constant-current source, makes from the LED lamp and lights.The control signal BatOutEn of simultaneously microprocessor output is that low level, control signal BatOutDis are high level, namely control emergency commutator switch module 3 and disconnect, thereby so that battery 8 not output voltage to the DC/DC constant-current source.
If alternating voltage normal power supply, but alternating voltage power down, then the STM8S003K microprocessor detects the AC dump signal, the control signal Charger Cutoff of microprocessor output this moment, Main Driver Cutoff, Stdby Driver Cutoff is low level, and control signal BatOutEn to be high level, control signal BatOutDis be that low level is STM8S003K microprocessor control emergency commutator switch module 3 closures, battery charger is disconnected, and the AC/DC Switching Power Supply can't be charged to battery 8.Simultaneously STM8S003K microprocessor control AC/DC master's constant-current source and AC/DC quit work from constant-current source, so AC/DC master's constant-current source and AC/DC can't be to power namely main LED lamps and extinguish from the LED lamp of a LED load 7 and the 2nd LED load 11 from constant-current source.Because it is closed that emergency commutator switch module 3 is emergency button, cell voltage will export by emergency commutator switch module 3 input of DC/DC constant-current source to, drive the DC/DC constant-current source main LED lamp is lighted, and system enters battery 8 discharge conditions.
In the alternating voltage power down, so that battery enters in the situation of discharge condition, if this moment, alternating voltage recovered normal, the STM8S003K microprocessor can be with control signal Charger Cutoff, Main Driver Cutoff, Stdby Driver Cutoff, BatOutEn and BatOutDis signal inversion are returned, make the battery charger conducting, the AC/DC Switching Power Supply is charged to battery 8 by battery charger, AC/DC master's constant-current source and AC/DC start working to main LED lamp with from the power supply of LED lamp from constant-current source, make the LED of winner lamp and all light from the LED lamp.
When the alternating voltage normal power supply, if when microprocessor got access to the discharge test signal, system entered battery discharge status with pressure.The control signal Main Driver Cutoff output low level of microprocessor output this moment, AC/DC master's constant-current source quits work, AC/DC master's constant-current source do not give a LED load 7 power supplies namely main LED lamp extinguish.The control signal Stdby Driver Cutoff of microprocessor output also is output low level, and AC/DC quits work from constant-current source, makes from the LED lamp to extinguish.The control signal Charger Cutoff output low level of microprocessor output, battery charger quits work, and charger is not to battery 8 chargings.Control signal BatOutEn exports high level, control signal BatOutDis output low level, make emergency commutator switch module 3 closures, battery 8 voltages will export by emergency commutator switch module 3 input of DC/DC constant-current source to, drive the DC/DC constant-current source main LED lamp is lighted, system enters battery 8 discharge conditions.
In the discharge test process, no matter whether alternating voltage changes, microprocessor can not change Main Driver Cutoff, Stdby Driver Cutoff, Charger Cutoff, the on off state of BatOutEn and BatOutDis, namely system can be in battery 8 discharge conditions always, until the discharge test process finishes when reaching default time value the discharge time of battery.The on off state that this moment, microprocessor will these 5 control signals carries out anti-phase, and this moment, the emergency commutator switch module 3 disconnected, and battery 8 is not exported.System turns back to the AC charging state, and Charger Cutoff signal becomes high level, the battery charger conducting, and charger is to battery 8 chargings.Simultaneously in the process of discharge test, the control microprocessor is controlled simultaneously battery voltage sensor, LED voltage sensor and current sensor and is started working, to detect the use state of battery and main LED lamp, owing to being optional lamp from the LED lamp, therefore do not need detecting from the LED lamp.When the voltage that detects main LED lamp less than the electric current of predeterminated voltage value, main LED lamp during less than the predetermined current value, the voltage of battery during less than the predeterminated voltage value or the discharge time of battery less than preset value, the output abnormality signal is the fault prompting to trouble light to carry out abnormal prompt.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
