Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment a part of embodiment that is the present invention, rather than whole embodiments.Based on this
Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
Embodiment one,
The embodiment of the present invention provides a kind of method of the standby time of accumulator determining communication base station, specifically as Fig. 1 institute
Show, comprising:
S101, the acquisition actual capacity of accumulator and the actual load of communication base station.
In a first aspect, needing in the embodiment of the present invention to obtain the actual capacity of accumulator.
At present, communications industry DC communication power system stand-by power supply mainly adopts lead-acid accumulator, it is preferred, therefore, that
Accumulator in the embodiment of the present invention is lead-acid accumulator.
Generally, the actual capacity of accumulator can be obtained by multiple methods, for example: discharge test, AC impedence method, open
Road voltage method, battery terminal voltage method, ampere-hour integration method, fuzzy prediction and neural network etc..In above-described numerous methods
In, discharge test is carried out to accumulator, can relatively accurately obtain the actual capacity of accumulator, it is preferred, therefore, that the present invention
Embodiment obtains the actual capacity of accumulator using the method that accumulator is carried out with discharge test.
Further, be may comprise steps of using the actual capacity that the method for discharge test obtains accumulator:
First, accumulator is carried out with the released capacity that discharge test obtains accumulator.
In real process, discharge test can be carried out to accumulator using offline electric discharge and online electric discharge two ways.
Specifically, offline discharge process includes: makes accumulator completely disengage from use environment first, then will be in fully charged state
Accumulator accesses in storage battery discharge equipment is discharged using current constant mode, obtains the released capacity of accumulator；Put online
Electric process includes: online discharge equipment is accessed in the loop that accumulator uses and is discharged online, in online discharge process
Actual load can be selected according to practical situation, thus obtaining the released capacity of accumulator.
The released capacity of accumulator is relevant with Multiple factors such as actual load, discharge time and final voltages.Therefore, when
When same accumulator adopts different discharge rates to discharge, the released capacity of accumulator is different.Table 1 lists lead-acid accumulator
Released capacity when being discharged with different discharge rates, actual load and final voltage.Exemplarily, the specified appearance of lead-acid accumulator
Measure as 1c, standard discharge rate is 10 hour rates, if by the electric discharge of its standard discharge rate 10 hour rate, that is, with the actual load of 0.1c
Electric discharge, the electricity of the rated capacity of accumulator can all be released by electric discharge 10h；If by 3 hour rate electric discharges, that is, with 0.25c
Actual load electric discharge, electric discharge 3h can release the electricity of 0.75 times of rated capacity of accumulator；If put by 1 hour rate
Electricity, is discharged with the actual load of 0.55c, and electric discharge 1h can release the electricity of 0.55 times of rated capacity.Usually, little with 10
When rate electric discharge when, the released capacity of lead-acid accumulator is maximum, when being discharged with other hour rates, the released appearance of lead-acid accumulator
Decreases in non-linear trend with the reduction of hour rate in amount.It is preferred, therefore, that embodiment of the present invention accumulator is put using standard
Electric rate 10 hour rate electric discharge.
Table one
Next, obtain actual capacity according to releasing capacity.
As seen from the above description, when accumulator is discharged with different discharge rates, the released capacity of accumulator is different.Cause
This, if the discharge rate of accumulator is standard discharge rate during discharge test, actual capacity is can to release capacity, usual standard
Discharge rate is 10 hour rates；If the discharge rate of accumulator is non-standard discharge rate during discharge test, actual capacity is can
Release the capacity of capacity gained after conversion.Exemplarily, the accumulator for 1c for rated capacity, is discharged with 1 hour rate
When, can release capacity is c1, then the actual capacity of accumulator is c1/0.55；So that, during 3 hour rate electric discharge, can release capacity is
C0.5, then the actual capacity of accumulator is c0.5/0.75.
Second aspect, needs in the embodiment of the present invention to obtain the actual load of communication base station.
Wherein, the actual load of communication base station, refers to the actual current of communication base station intercom set.

If it is determined that parameter is more than or equal to the 5th setting value, determine that the standby time is more than or equal to 5h.
Wherein, the process obtaining setting value can be such that
First, obtain accumulator as the minimum standby time of the communication base station of stand-by power supply.
Specifically, the minimum standby time of accumulator can be determined according to the concrete application of accumulator.Exemplarily, root

Accumulator, the minimum standby time is respectively 1h, 2h, 3h, 4h, 5h.
Secondly, setting value is obtained according to the minimum standby time.
Specifically, setting value is the ratio divided by actual load gained for the rated capacity of accumulator, wherein this actual load
It is using load during minimum standby time as discharge time.Exemplarily, when the minimum standby time being 1h, the volume of accumulator
Constant volume is 1c, and actual load is 0.55c, obtains the first setting value, and the first setting value is 1.9.
Exemplary, below according to the process of above-mentioned acquisition setting value, provide the right of one group of critical parameter and standby time

| 3 | ≥3.03 | ≥2h |
| 4 | ≥4 | ≥3h |
| 5 | ≥5 | ≥4h |
| 6 | ≥5.9 | ≥5h |
It should be noted that above-mentioned is only the exemplary corresponding relation providing one group of critical parameter and standby time,
