Embodiment
The structural representation of a kind of electric supply installation that Fig. 1 provides for the embodiment of the invention.As shown in Figure 1, electric supply installation comprises: super capacitor 11, battery 12, control circuit 13, power-fail detection circuit 14 and notification unit 15.
Whether whether power-fail detection circuit 14 power on after power down or the power down for detection of the primary power of storage system.
Control circuit 13 links to each other with super capacitor 11, battery 12 and power-fail detection circuit 14, and in the situation for the primary power power down that detects storage system at power- fail detection circuit 14,11 discharges of control super capacitor are the master control borad power supply of storage system; Control circuit 13 also is used for when super capacitor surpasses scheduled duration 11 discharge times, and control battery 12 be that the master control borad of this storage system is powered.Wherein, scheduled duration can be the discharge time that super capacitor can satisfy the master control borad operation of storage system.Suppose that the duration that super capacitor can discharge is M, after can doing derate and process the discharge duration of super capacitor so, as scheduled duration m, m<M.When the duration that can discharge such as super capacitor was 50s, so, scheduled duration was 35s, for super capacitor stays certain allowance, cut off the power supply before the powered battery avoiding, and guaranteed the power supply that can seamlessly continue of super capacitor and battery.
Notification unit 15 can link to each other with control circuit 13, is used for when control circuit 13 control batteries 12 are the master control borad power supply of this storage system, and notification unit 15 notifies the master control borad of this storage system to carry out the power down protection flow process.The master control borad that this power down protection flow process is storage system is preserved the flow process of critical data, specifically can be carried out by the program of moving on the master control borad.Wherein, the critical data of preservation is the data in the internal memory on the master control borad.
Notification unit 15 also can link to each other with power-fail detection circuit 14.Because control circuit 13 control battery 12 when 11 discharge times of super capacitor surpass scheduled duration (being assumed to be T) is the master control borad power supply of storage system; and super capacitor is when reaching T 11 discharge times; also just substantially equal the time of the primary power power down of storage system; therefore; notification unit 15 can link to each other with power-fail detection circuit 14; informed the when power down of primary power of notification unit 15 storage systems by power-fail detection circuit 14; then power-fail detection circuit 14 is when the duration of the primary power power down of storage system reaches T; when also being control circuit 13 control batteries 12 for the master control borad power supply of this storage system, the master control borad of notification unit 15 notice storage systems is carried out the power down protection flow process.
Perhaps, notification unit 15 can all link to each other with control circuit 13 and power-fail detection circuit 14, in this case, the duration of the discharge duration of super capacitor 11 or the primary power power down of storage system can carry out timing control by notification unit 15, when notification unit 15 is known the primary power power down of storage system by power-fail detection circuit 14, the beginning timing.When timing reaches above-mentioned scheduled duration, but notification unit 15 trigger control circuit 13 control batteries 12 are the master control borad power supply of above-mentioned storage system.
