In power failure warning circuit i.e. provided in an embodiment of the present invention, the energy-storage units 203 in power failure warning circuit are charged using the method for high-voltage charging, improve the energy storage density of energy-storage units 203, so as to reduce the volume of accumulation power supply 203, and then the volume of power failure warning circuit can be reduced so that the network equipment of some small volumes can also realize Dying gasp functions.
It is preferred that, power failure warning circuit shown in Fig. 2, filter unit 206 can also be included, as shown in Figure 3, filter unit 206, for before detection unit 205 exports power fail warning signal to the late-class circuit of power failure warning circuit, processing to be filtered to the power fail warning signal, signal burr is removed, makes power failure warning circuit more stable reliable.
When implementing, filter unit 206 can be, but not limited to realize using CPLD (Complex Programmable Logic Device, CPLD) or integrated single channel.
Above-mentioned reverse-filling unit 201 can be realized using diode.
Preferably, above-mentioned reverse-filling unit 201 is realized using the less gate-controlled switch device of the conduction voltage drops such as metal-oxide-semiconductor, power failure warning circuit can be made suitable for the less application scenarios of some input supply voltages.
For example, when in SFP ONT, SFP ONT power supply is that the input power of power failure warning circuit is smaller, for 3.3V, reverse-filling unit 201 is realized according to diode, the conduction voltage drop of diode is about 0.7V, when the input power of power failure warning circuit is opened, the input power of power failure warning circuit is only 2.5V for the operating voltage that the late-class circuit of power failure warning circuit is provided by reverse-filling unit 201, it is likely that be unsatisfactory for the power demands of late-class circuit.And reverse-filling unit 201 is realized according to metal-oxide-semiconductor, the conduction voltage drop very little of metal-oxide-semiconductor ensure that the input power of power failure warning circuit passes through reverse-filling unit 201

When implementing, above-mentioned boosting unit 202 can be, but not limited to realize using boost chip of the prior art.Power fail warning signal can also as boosting unit 202 control signal, the working condition for controlling boosting unit 202.When filter unit 206 does not export power fail warning signal, illustrate that the input power of now power failure warning circuit is opened, boosting unit 202 should be at working condition, boosting processing is carried out to the voltage of the input power of power failure warning circuit, is the high-voltage charging of energy-storage units 203；When filter unit 206 exports power fail warning signal, illustrate that the input power of now power failure warning circuit is closed, power fail warning signal triggering boosting unit 202 switches to closed mode by working condition, does not carry out boosting processing to the voltage of the input power of power failure warning circuit.
However, in fact, when the input power of power failure warning circuit is closed, boosting unit 202 will not work naturally without input, so substantially boosting unit 202 can also not need control signal.
When implementing, above-mentioned energy-storage units 203 can be, but not limited to realize using energy storage devices such as electric capacity, batteries.
Further, output control unit 204, when the input power of power failure warning circuit is opened, not to the late-class circuit output voltage of power failure warning circuit.
Preferably, power fail warning signal can as output control unit 204 control signal, the output state for controlling output control unit 204.When filter unit 206 does not export power fail warning signal, illustrate that the input power of now power failure warning circuit is opened, output control unit 204 is not to the late-class circuit output voltage of power failure warning circuit；When filter unit 206 exports power fail warning signal, illustrate that the input power of now power failure warning circuit is closed, the power fail warning signal triggers output control unit 204 and exports burning voltage to the late-class circuit of power failure warning circuit.
When implementing, above-mentioned output control unit 204 can be, but not limited to realize using voltage-stabilizing devices such as LDO (Low Dropout Regulator, low pressure difference linear voltage regulator).
When implementing, above-mentioned detection unit 205 can be realized using comparator.
In one particular embodiment of the present invention, detection unit 205, specifically for determining whether the voltage of input power of power failure warning circuit is less than predeterminated voltage；When it is determined that the voltage of the input power of power failure warning circuit is less than predeterminated voltage, determine that the input power of power failure warning circuit is closed, detection unit 205 exports power fail warning signal to the late-class circuit of power failure warning circuit；When it is determined that the voltage of the input power of power failure warning circuit is not less than predeterminated voltage, determine that the input power of power failure warning circuit is opened, detection unit 205 does not export power fail warning signal to the late-class circuit of power failure warning circuit.
In another specific embodiment of the present invention, detection unit 205, specifically for determining whether the voltage of input power of current time power failure warning circuit is less than the voltage of the input power of last moment power failure warning circuit；It is determined that current time power failure warning circuit input power voltage be less than last moment power failure warning circuit input power voltage when, determine that the input power of power failure warning circuit is closed, detection unit 205 exports power fail warning signal to the late-class circuit of power failure warning circuit；It is determined that current time power failure warning circuit input power voltage be less than last moment power failure warning circuit input power voltage when, determine that the input power of power failure warning circuit is opened, detection unit 205 does not export power fail warning signal to the late-class circuit of power failure warning circuit.
Below in conjunction with the accompanying drawings, the implementing for power failure warning circuit that the present invention is provided is illustrated.

In Fig. 5, when the voltage of the input power of power failure warning circuit is not less than predeterminated voltage, detection unit 205 exports a low level signal, represents that the input power of power failure warning circuit is opened；When the voltage of the input power of power failure warning circuit is less than predeterminated voltage, detection unit 205 exports a high level signal, represents that the input power of power failure warning circuit is closed；The high level signal is power fail warning signal, by filter unit 206 filter after export.
The power fail warning signal that filter unit 206 is exported serves not only as the trigger signal of the late-class circuit transmission Dying gasp message of power failure warning circuit, also as the control signal of reverse-filling unit 201, boosting unit 202 and output control unit 204.
Specific implementation based on reverse-filling unit 201 and detection unit 205 in Fig. 5, the power fail warning signal that filter unit 206 is exported needs the metal-oxide-semiconductor control end being input to after reversely in reverse-filling unit 201, can realize the correct logic control to reverse-filling unit 201.Therefore, signals reverse circuit 500 is provided with Fig. 5 to realize the reverse of power fail warning signal.Certainly, the signals reverse process can also be realized in filter unit 206, and the present invention is not limited this.
When the input power of power failure warning circuit is opened, the voltage of the input power of power failure warning circuit is not less than predeterminated voltage, filter unit 206 does not export power fail warning signal, metal-oxide-semiconductor conducting in reverse-filling unit 201, metal-oxide-semiconductor shut-off in output control unit 204, the input power of power failure warning circuit provides operating voltage for the late-class circuit of power failure warning circuit, and carries out high-voltage charging to the electric capacity in energy-storage units 203 by the boost chip in boosting unit 202.
Now, the LDO in output control unit 204 is although in running order, but the metal-oxide-semiconductor shut-off in output control unit 204, and LDO is unloaded, and power consumption is relatively low.
When the input power of power failure warning circuit is closed, the voltage of the input power of power failure warning circuit is less than predeterminated voltage, filter unit 206 exports power fail warning signal, the late-class circuit for triggering power failure warning circuit sends Dying gasp message, and trigger the shut-off of the metal-oxide-semiconductor in reverse-filling unit 201, metal-oxide-semiconductor conducting in output control unit 204, electric capacity in energy-storage units 203 provides stable operating voltage by output control unit 204 for the late-class circuit of power failure warning circuit, exhausted up to the capacitive energy in energy-storage units 203 is close, untill LDO in output control unit 204 can not carry out voltage stabilizing output again.
It can be seen that, the energy of energy-storage units 203 is used to the transmission of the late-class circuit Dying gasp message of power failure warning circuit, and the utilization rate of energy is higher；Also, power failure warning circuit is preferable for the stable operating voltage that late-class circuit is provided.

In Fig. 6, when the voltage for the input power that the voltage of the input power of current time power failure warning circuit is not less than last moment power failure warning circuit, detection unit 205 exports a low level signal, represents that the input power of power failure warning circuit is opened；When the voltage for the input power that the voltage of the input power of current time power failure warning circuit is less than last moment power failure warning circuit, detection unit 205 exports a high level signal, represents that the input power of power failure warning circuit is closed；The high level signal is power fail warning signal, by filter unit 206 filter after export.
