Description
Technical field
The present invention relates to detecting voltage, adjustment of load technology, and in particular to a kind of extension for Dying Gasp functions
The method for powering off the retention time.
Background technology
In order to ensure that the stable of business runs without interruption in communication network, the status monitoring of the network equipment is that to possess
Function, and Dying Gasp functions are then a kind of monitoring alarm methods to device power supply (DPS).Its principle is exactly monitoring input electricity
Pressure, the energy storage of energy storage component (bulky capacitor, battery etc.) in equipment is utilized to send out equipment final state information when inputting and powering off
See off., it is necessary to which the Dying Gasp response times protect no more than power-off retention time, power-off during whole function is realized
It is usually to be realized by bulky capacitor to hold the time, so in the case of heavier loads, in order to meet time requirement, to the big of electric capacity
Small, quantity all generates larger pressure, also has larger pressure similarly for the layout of equipment, so breaking under same energy storage
The extension of electric retention time is just extremely necessary.
The content of the invention
The method of a kind of extension power-off retention time for Dying Gasp functions proposed by the present invention, for ensureing
The Dying Gasp functional response times, it is possible to achieve under same energy storage, power off the extension of retention time.
To achieve the above object, present invention employs following technical scheme：
A kind of method of extension power-off retention time for Dying Gasp functions, including alarm for power-off universal circuit,
Regulating circuit, the power control circuit containing logical devices such as CPLD, the power control circuit without logical devices such as CPLD, its
In,
Alarm for power-off universal circuit is used to produce alarm for power-off signal；
Circuit used in the one-level adjustment of load content that regulating circuit is used in adjustment of load；
Power control circuit containing logical devices such as CPLD and the power control circuit without logical devices such as CPLD are negative
Circuit used in the three-level adjustment of load content in adjustment is carried, carries out selecting the former according to whether product contains the logical devices such as cpld
Or the latter uses；
Comprise the following steps：
Step 1：Adjustment of load measure is reserved in product design as needed；
Step 2：After power-off, alarm for power-off signal is produced；
Step 3：After receiving alarm for power-off signal, implement adjustment of load measure；
Step 4：Send Dying Gasp signals.
Further, the step 1 also includes three level load Suitable contents, according to sending Dying Gasp signals institute
Take time and carry out balance selection one or more adjustment of load measure.
From the foregoing, it will be observed that the present invention is down to reduce equipment in guarantee Dying Gasp correlation functions according to alarm for power-off signal
Power consumption, and then to extend the power-off retention time i.e. by way of adjusting rear end power consumption to extend the time.In adjustment of load content
In adjustment of load content is classified, while also to selection give direction and implementation.
The method of extension power-off retention time for Dying Gasp functions of the present invention a kind of, can reduce energy storage electricity
Size, quantity and the arrangement space of appearance.

Embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is the theory diagram of the present invention, and alarm for power-off module 001 obtains alarm signal and then triggers adjustment of load module
002 carries out adjustment of load, final to realize that the power-off retention time extends.Detailed process combination Fig. 1 is described as follows：Input voltage 101
Comparison amplifier 103 is sent into after partial pressure is carried out by bleeder circuit 102 and obtains alarm for power-off signal, and according to weighing selection
Adjustment of load content 104 carries out implementing adjustment of load 105.
Fig. 2 is a kind of general alarm for power-off observation circuit.Because the input voltage for whole equipment power supply typically compares
Height, so need by being sent into comparison amplifier after voltage division processing, and reference voltage is compared, and input voltage is realized with this
Comparison amplifier output voltage logic level change, that is, alarm signal logic level change are triggered during less than certain value；Wherein
Comparison amplifier can use individual devices to use other chips containing this function, such as MAX706.
Influence size according on functions of the equipments come fixed when Fig. 3 is three-level Suitable content, at the same be also according to cost performance by
It is high to Low to arrange.
One-level Suitable content is miscellaneous function, is not the function of externally providing, the long-term normal work for auxiliary equipment
Make, so being reduced or turned off miscellaneous function when power is off does not influence overall outside function, and because the general work(of miscellaneous function
Rate is bigger, and the extension that the retention time is powered off after adjustment can be obvious, and cost performance is higher.Such as：Fan adjusts, if equipment
Fan supports gear adjustment, gear can be directly transferred into minimum, if it does not, can the control by way of Fig. 5 or Fig. 6
Power cut-off processed；Heating adjustment, can control the voltage of heater circuit by the way of Fig. 4, and heating power is realized with this
Adjustment, can also break heater circuit power supply using Fig. 5 or Fig. 6 mode
Two level Suitable content has involved equipment and externally provides function, but not comprising Dying Gasp interlock circuits and
Chip, circuit need not be changed by adjusting this partial content, realize correlation function on software, such as irrelevant port shutdown,
Irrelevant chip enters sleep pattern, radio-frequency enabled closing etc., only retains Dying Gasp correlation functions
Three-level Suitable content is similar with two level Suitable content, but Fig. 5 ＆ Fig. 6 power-off or Fig. 4 pressure regulation by way of come
Realize, can more save power supply, but need to support on hardware at the beginning of design.
Fig. 4 be a kind of simple regulating circuit, it is necessary to which DCDC or LDO is supported, and different voltage associated peripheral circuits change
Less, dividing ratios can be adjusted to adjust output voltage by adjusting feedback pins resistance to earth.
Fig. 5 carries out the circuit of sequential and power supply using logical devices such as CPLD.Wherein first have to ensure CPLD's
Power supply first produces.The power supply requirement of rear end is divided into two parts, one is to be used to support Dying Gasp correlation functions
Circuit, another is can to close power circuit.If cost is not very sensitive, independent DCDC or LDO can be used
To separate power supply；If cost sensitivity can increase the switch controls such as PMOS, it is necessary to shared power supply between this two parts circuit
System, it is contemplated that the pressure drop of switch, voltage above will somewhat positively biaseds.
Fig. 6 is when logical devices such as no CPLD, directly goes control to power with alarm for power-off signal.Sequential is by sequential control
Signal processed controls, and powering off timing control signal and alarm for power-off signal can control.Ibid, circuit is divided into two
Point, if powered using independent DCDC or LDO, it is only necessary to which alarm for power-off signal is accessed to the control circuit of aft section；Such as
Fruit shares power supply, it is necessary to be gone to control PMOS switch with this signal, equally to consider pressure drop and positively biased requirement.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, all should fall within the scope of protection of the present invention.
