In the charge-discharge circuit, D14 is a commutation diode, and D15 is a Schottky diode, and Q4, Q5, Q6, Q7 are the switching mode triodes, and Q4, Q5 are 8550, positive-negative-positive triode, more withstand voltage anti-stream; And Q6, Q7 are 8050, NPN type triode, and power consumption is less.Control Q6 switch can be controlled the Q4 switch, and then realizes the charging control to battery, and battery detecting can be carried out in C7 electric capacity two ends.Discharge portion is as shown in Figure 9, and the same charging control circuit of implementation method is realized can carrying out light source detection at C10 electric capacity two ends to the discharge control of battery through Q5, Q7.1117 are step-down transformation chip in the reduction voltage circuit, and this circuit is the key modules of live part circuit, in the circuit 8V voltage is carried out voltage transformation.1117 chips have totally three pins, a ground connection, and one connects input voltage, another output voltage.From input pin input 8V voltage, output pin output 3.3V voltage charges for battery, and C13, C14 are two polar capacitors, play the effect of rectification.

The signal acquisition testing of emergency light switch power module and emergency light control design comprise that the 220V alternating current detects and corresponding control and battery and light source detection and corresponding control.Whether be mainly used in detection 220V voltage and turn-off, whether emergency light need get into contingency mode.Detection method was carried out current limliting and dividing potential drop to civil power before this, again the value after its dividing potential drop was made detection.In order to prevent near emergency light switch repeatedly some magnitudes of voltage; Scheme is given up a certain point voltage value of employing as the contingency mode threshold value; And adopting the mode that is similar to the Schmidt trigger form to carry out the judgement of emergency light contingency mode, concrete implementation is shown in figure 11.When voltage from 220V drop to 132V when following light fixture get into emergency rating, when voltage light fixture when 90V rises to 186V recovers normal condition.

Battery and the light source detection and the corresponding control of signal acquisition testing and emergency light control design mainly are meant battery and led light source port are carried out voltage measurement.When magnitude of voltage low represent battery or light source short circuit, phase antirepresentation open circuit during certain numerical value.Simultaneously, the existing electric weight of battery is made real-time measurement.

The control scheme of battery and light source is made judgement according to detection case.Charging, discharge lay respectively at two ports, and for the accuracy that guarantees to detect, these two ports do not allow to open simultaneously.

In normal operation, module is in charged state always, and discharge portion turn-offs.

Under standby mode of operation, module is in discharge condition, and live part turn-offs.

Under the fail operation state,, discharge and recharge all and will turn-off for holding circuit.

In order to protect the service life of battery, the scheme utilization is regularly charged and the charging dual mode is pressed in power taking:

Regularly the charging interval of charging is 17 hours, on the timing charge function, can calculate the charging interval (to prevent over-charging of battery or undercharge) according to the capacity that battery is emitted automatically.

Power taking is pressed charging to have voltage-limiting protection simultaneously and is regularly protected two functions; During the different battery charge of internal resistance; Cell voltage can not rise to setting value; Thereby circuit also can prevent that over-charging of battery from damaging by the charge closing state in the certain hour section, and circuit is transferred to charged state automatically when voltage drops to certain value.
