Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's acquired every other implementation without creative efforts
Example, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a kind of brightness control methods of street lamp.The control method of the embodiment of the present invention is especially suitable
In the street lamp using solar power generation.As shown in Figure 1, this method specifically includes following step:
Step S101: it obtains using the time to be controlled as the unit of the battery of the street lamp in the first preset time of end time
The unit time discharge capacity of battery in time charge volume and the second preset time before the time to be controlled.
Wherein, the time span of the first preset time is identical with the time span of the second preset time.In general, first is pre-
If time and the second preset time are 7 days, then the unit time is daily, and unit time charge volume is daily charge volume, single
Position time discharge capacity is daily discharge capacity.It should be understood that different according to daily actual conditions, daily charge volume and
Daily discharge capacity can all change.Because charging is usually to carry out when not illuminating (usually daytime) on the day of, on the day of
Before illumination, the charge volume on the same day can be collected, therefore, the end time of the first preset time is set as the time to be controlled.It puts
Electricity carries out when being usually illumination (usually at night) on the day of, after illuminating on the day of, can just collect the electric discharge on the same day
Amount, therefore, the end time of the second preset time are set as the timing node (such as the previous day) before the time to be controlled.
For example, the first preset time and the second preset time are 7 days, the time to be controlled is No. 10, then first it is default when
Between include: No. 4~No. 10, the unit time charge volume in the first preset time includes: No. 4~No. 10 daily charge volumes；The
Two preset times include: No. 3~No. 9, and the unit time charge volume in the second preset time includes: No. 3~No. 9 daily electric discharges
Amount.
Step S102: it according to the unit time charge volume in the first preset time, is calculated in the first preset time
Average charge amount.
Average charge amount in first preset time be equal to the sum of the unit time charge volume in the first preset time divided by
The quantity of unit time.For example, the first preset time is 7 days, then the average charge amount in the first preset time=(fill for first day
+ the second day charge volume of electricity+...+the seven day charge volume)/7 days.
Step S103: it according to the unit time discharge capacity in the second preset time, is calculated in the second preset time
Mean discharge magnitude.
Mean discharge magnitude in second preset time be equal to the sum of the unit time discharge capacity in the second preset time divided by
The quantity of unit time.For example, the second preset time is 7 days, then the mean discharge magnitude in the second preset time=(first day puts
+ the second day discharge capacity of electricity+...+the seven day discharge capacity)/7 days.
Step S104: according to the mean discharge magnitude in the average charge amount and the second preset time in the first preset time
Size relation controls the brightness of the street lamp of time to be controlled.
According to the size relation of the mean discharge magnitude in the average charge amount and the second preset time in the first preset time,
The brightness of the street lamp of time to be controlled can be specifically controlled according to three kinds of following situations.
(1) if the average charge amount in the first preset time is reduced less than the mean discharge magnitude in the second preset time
The brightness of street lamp.
Specifically, as shown in Fig. 2, the process specifically includes:
Step S201: if average charge amount in the first preset time less than the mean discharge magnitude in the second preset time,
The first difference of the average charge amount in the mean discharge magnitude in the second preset time and the first preset time is then calculated.
If the average charge amount in the first preset time less than the mean discharge magnitude in the second preset time, illustrates at present
The practical electricity that can be used is less than the electricity consumed daily, and if things go on like this, the electricity of battery can be lower and lower, therefore, needs
Reduce the brightness of street lamp.The step subtracts being averaged in the first preset time with the mean discharge magnitude in the second preset time and fills
Electricity.
Step S202: the quotient of the first difference and charge volume Trend value is calculated, the reduction amplitude of the brightness of street lamp is obtained.
Specifically, charge volume Trend value is the average charge amount in the first preset time and the end by the time of the time to be controlled
The quotient of average charge amount in the third preset time of point.Wherein, the length of third preset time is not less than the first preset time
Length, and be not more than maximum preset time span.Maximum preset time span is generally 30 days, when thus being avoided that third is preset
Between the longer and recent battery working condition of length have certain deviation.Additionally, it should be understood that when the unit of storage
The corresponding time span of time charge volume meets maximum preset time span, then the length of third preset time is preferably maximum pre-
If time span.Only when the corresponding time span of unit time charge volume of storage is unsatisfactory for maximum preset time span,
Make the corresponding time span of the obtainable unit time charge volume of the length of third preset time.
Charge volume Trend value is greater than 1, shows that illumination is more and more stronger；Conversely, charge volume Trend value less than 1, shows that illumination is got over
Come weaker.Charge volume Trend value is to prevent from disposably adjusting to correct the amplitude for improving street lamp brightness and reducing street lamp brightness
Excessively.
For example, although average charge amount in the first preset time is less than the mean discharge magnitude in the second preset time,
It is that charge volume Trend value is greater than 1, then illustrates that collected solar energy is being continuously increased daily, then the reduction of the brightness of street lamp needs
The variation for considering this part, cannot excessively be adjusted.Therefore, this step is by the first difference divided by charge volume Trend value.
For example, the first preset time is 7 days, maximum preset time span is 30 days, then third preset time is at least 7
It, and no more than 30 days.For example, the time to be controlled is No. 20, when corresponding by the end of No. 20 accumulative unit time charge volumes
Time span when being only 8 days, then the time span of third preset time is 8 days, and third preset time includes: No. 14~20
Number.
Step S203: judge whether the unit time discharge capacity of battery is small according to after the brightness for reducing amplitude reduction street lamp
In the unit time of battery minimum discharge capacity limit value.
Wherein, the unit time of battery minimum discharge capacity limit value is equal to street lamp wattage, presupposition multiple and street lamp unit time
Illumination duration product one thousandth.Street lamp wattage is determined by the model of street lamp (usually LED) itself.Presupposition multiple can
Rule of thumb set.In general, presupposition multiple uses percentage meter.The minimum limit value of presupposition multiple is 5%, and presupposition multiple is most
Big limit value is 100%.The illumination duration of street lamp unit time is generally rule of thumb set.When the unit time is day, when unit
Between illumination when a length of illumination duration every night.
For example, the wattage of street lamp is 40w, presupposition multiple 5%, when street lamp illumination every night a length of 7h, then can count
Calculating minimum discharge capacity limit value daily is 40 × 5% × 7/1000=0.014.
The unit time discharge capacity of battery cannot ad infinitum decline, and avoid that illumination can not be played the role of, therefore, it is necessary to sentence
After disconnected reduction brightness, whether the unit time discharge capacity of battery is less than unit time minimum discharge capacity limit value.
Step S204: if being not less than, according to the amplitude of reduction, the brightness of street lamp is reduced.
Step S205: if being less than, the corresponding street lamp of unit time minimum discharge capacity that street lamp brightness is battery is controlled
Brightness.
Through the above steps, if the average charge amount in the first preset time is put less than being averaged in the second preset time
Electricity, the then amplitude for taking different modes to be reduced according to the actual situation, to control the brightness for reducing street lamp.
(2) it if the average charge amount in the first preset time is greater than the mean discharge magnitude in the second preset time, improves
The brightness of street lamp.
Specifically, as shown in figure 3, the process specifically includes:
Step S301: if the average charge amount in the first preset time is greater than the mean discharge magnitude in the second preset time,
The second difference of the average charge amount in the first preset time and the mean discharge magnitude in the second preset time is then calculated.
If the average charge amount in the first preset time is greater than the mean discharge magnitude in the second preset time, illustrate at present
The practical electricity that can be used is greater than the electricity consumed daily, it is thus possible to improve the brightness of street lamp.The step is pre- with first
If the average charge amount in the time subtracts the mean discharge magnitude in the second preset time.
Step S302: the first product of the second difference and charge volume Trend value is calculated, the raising width of the brightness of street lamp is obtained
Degree.
The charge volume Trend value is identical as the meaning of charge volume Trend value above-mentioned, and details are not described herein.
For example, although average charge amount in the first preset time is greater than the mean discharge magnitude in the second preset time,
It is charge volume Trend value less than 1, then illustrates that collected solar energy is constantly being reduced daily, then the raising of the brightness of street lamp needs
The variation for considering this part, cannot excessively be adjusted.Therefore, this step is by the second difference multiplied by charge volume Trend value.
Step S303: after judging the brightness according to increase rate raising street lamp, whether the brightness power of street lamp is greater than power supply
Appointing in the payload power of controller, the maximum value of street lamp intrinsic brilliance power and the power of street lamp preset maximum brightness
One.
The unit time discharge capacity of battery cannot ad infinitum increase, and avoid battery over-discharge and lead to the use longevity for shortening battery
Life, therefore, it is necessary to judge after increasing brightness, whether the brightness power of street lamp is greater than the payload power of power-supply controller of electric, road
Any of the maximum value of lamp intrinsic brilliance power and the power of street lamp preset maximum brightness.The effective of power-supply controller of electric bears
It is usually preset to carry power.The maximum value of street lamp intrinsic brilliance power can be obtained by actual measurement.Street lamp is default most light
The power of degree is usually preset.
Step S304: if being not more than, according to increase rate, the brightness of street lamp is improved.
Step S305: if more than it is actually bright for payload power, the street lamp of power-supply controller of electric then to control the brightness of street lamp
Spend the brightness of the maximum value of power and one corresponding street lamp of minimum in the power of street lamp preset maximum brightness.
The maximum value and street lamp preset maximum brightness of the payload power of power-supply controller of electric, street lamp intrinsic brilliance power
Power, these three values are generally different.Therefore, in order to protect battery, in the case of this kind, control street lamp brightness be the three in most
The brightness of a small corresponding street lamp.
(3) it if the mean discharge magnitude in the first preset time is equal to the average charge amount in the second preset time, keeps
The brightness of street lamp.
Therefore, the brightness control method of the street lamp of the embodiment of the present invention, can according in the first preset time charge volume and
The size relation of discharge capacity in second preset time, respectively in connection with the unit time minimum discharge capacity limit value of battery, power supply control
Payload power, the maximum value of street lamp intrinsic brilliance power and the power of street lamp preset maximum brightness of device processed, so as to true
The amplitude of variation of brightness is determined, so as to preferably control the brightness of street lamp；This method passes through the historical data assessment to charge and discharge
It is estimated with to future weather variation tendency, obtains the reasonable brightness of street lamp next time, effectively control discharge power, avoided completely
The management of charging and discharging mode of randomness, though in plum rain season, in the case of this method is not it is also ensured that have sunshine in 15 days, street lamp
It can continuous work；Meanwhile using the variation of the practical electricity of charge and discharge as foundation, battery capacity is adapted to the increasing of charging times
Add and constantly reduce this rule, adjust charge-discharge parameter, effectively avoids the over-discharge behavior of battery, protection battery will not be anti-because of low pressure
Multiple charge and discharge cause possible permanent damage.
In addition, if the corresponding time span of quantity of the unit time charge volume of the battery of record is less than the first preset time
Time span can not effectively control the brightness of street lamp according to the method described above then since the historical data of accumulation is inadequate.So,
As shown in figure 4, brightness of the method for the embodiment of the present invention according to following step control street lamp:
Step S401: the voltage of battery is detected.
Step S402: according to the voltage of battery, the brightness of the street lamp of time to be controlled is controlled.
Specifically, step S402 is again specifically according to the following two kinds feelings according to the size relation of cell voltage and voltage limits
Condition carries out:
The first situation:
If the voltage of battery controls the brightness of street lamp according to the power of the predetermined luminance of street lamp not less than voltage limits
For the corresponding brightness of power of predetermined luminance.
If the voltage of battery is not less than voltage limits, show that battery is in normal condition, it can be according to the function of predetermined luminance
The brightness of rate control street lamp.The power of the predetermined luminance can rule of thumb be set, and can meet normal illumination.Under normal circumstances, in advance
If brightness is no more than preset maximum brightness above-mentioned.
Second situation:
(1) if the voltage of battery is less than voltage limits, being associated with for the power of the brightness of street lamp and the voltage of battery is obtained
Relationship.
The incidence relation is generally rule of thumb preset.If the voltage of battery is less than voltage limits, show that battery is in different
Normal state needs to control the brightness of street lamp according to the incidence relation, to avoid damage battery.
Specifically, can be different gears by the power divider of brightness, the voltage range of battery be divided into different shelves
Position, establishes the incidence relation of the gear of the power of brightness and the gear of voltage range.The incidence relation can effectively ensure that illumination effect
While fruit, the damage to battery is effectively avoided.
(2) according to incidence relation, the power for controlling brightness of the brightness of street lamp for the associated street lamp of voltage of battery is corresponding
Brightness.
For example, the gear of the power of the brightness of the corresponding street lamp of voltage A is a, then according to the brightness of the corresponding street lamp of gear a
Power, control the brightness of street lamp.
It therefore,, can basis when not accumulating enough historical datas by the brightness control method of above-mentioned street lamp
The voltage of battery and the size relation of voltage limits, control the brightness of street lamp, so as at least guarantee not charge to battery, and even
Continuous 3~5 days without in the case of sunshine, street lamp can continuous work and be not in serious battery over-discharge situation, to be conducive to
The service life of battery.
In addition, requiring to pay attention to battery no matter according to the actual situation using the brightness of above-mentioned any method control street lamp
Electricity.
It is preferred, therefore, that as shown in figure 5, this method include the steps that it is as follows:
Step S501: the unit time minimum discharge capacity limit value that battery is calculated multiplies with the second of the 4th preset time
Product.
Wherein, length of the length of the 4th preset time less than the second preset time.In general, the 4th preset time of setting
It is 5 days.The unit time of the battery, minimum discharge capacity limit value obtained as the method previously described.
Step S502: calculate the second product and battery capacity protection value and, obtain the discharge capacity practical limit of battery.
Battery capacity protection value be it is preset, it is different according to the difference of battery size.
Step S503: it if the discharge capacity of battery reaches discharge capacity practical limit, minimum is put according to the unit time of battery
The brightness of the corresponding street lamp of electricity limit value, controls the brightness of street lamp.
If the discharge capacity of battery reaches discharge capacity practical limit, need to reduce power, to avoid damage battery.
Therefore, either street lamp installation initial stage do not have historical record for reference when, still add up enough history
When record for reference, the corresponding emergency plan of the above method can be used, be had while guaranteeing street lighting effect
Effect ground protection battery.
It is furthermore preferred that will seriously be unfavorable for electricity if being further continued for illuminating when the discharge capacity of battery reaches battery capacity protection value
The service life in pond, therefore, in order to avoid such case, the method for the embodiment of the present invention further include:
If the discharge capacity of battery reaches battery capacity protection value, street lamp closing is controlled.
Through the above steps, reach battery capacity protection value in the discharge capacity of battery, close street lamp, avoid making battery
At biggish loss.
To sum up, the brightness control method of the street lamp of the embodiment of the present invention is suitable for environmental change and accessory aging, solves to make
With in the process because battery performance declines, battery accelerated ageing and street lamp often cannot normal works caused by continuous without sunlight weather
The problem of making, the independent solar road lamp system especially suitable for no external power supply.
