Description of drawings
Fig. 1 is the system module structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
With reference to Fig. 1, a kind of outdoor electronic timer battery power supply system comprises battery pack, and battery pack connects the step-up/down module respectively, battery electric quantity monitoring modular, management of charging and discharging module;
The step-up/down module is used to obtain a stable system works voltage;
The battery electric quantity monitoring modular is used to monitor battery, and whether real-time notice need discharge and recharge, and realizes the calculating of system's dump energy work duration simultaneously according to algorithm;
The management of charging and discharging module is used to control external power source and battery powered automatic switchover.
In concrete the production, the scoreboard that often uses adopts the batteries power supply, and the scoreboard that does not often use adopts lithium electricity battery pack or the power supply of Ni-MH battery group.
The system works flow process:
Adopt battery pack to reach the operating voltage of demand; Because the battery set charge/discharge voltage deviation is bigger; Display effect there is very big influence, can obtains a stable system works voltage to obtain stable, a lasting display effect through the step-up/down module.Through electric quantity monitoring module monitors battery, whether real-time notice need discharge and recharge, and can realize the calculating of system's dump energy work duration simultaneously according to algorithm, obtains better result of use, avoids some unnecessary problems.
Use outdoor electronic timer battery power supply system, be full of electricity back scoreboard service time >=8 hour continuously.
The battery dump energy computational algorithm:
What of battery dump energy are the method that employing combines with current integration, voltage monitoring can well follow the tracks of, and below are this algorithm design thinking.
Battery charge and discharge process is carried out integration, just can obtain the size of battery dump energy, that is: battery dump energy=battery charge total amount-battery discharge total amount.But under the long-term obsolete working condition of battery; Different batteries have different self discharge speed; This depends on factors such as charged state, battery temperature, battery charging and discharging circulation history, the internal resistance of cell; Promptly this algorithm can not obtain the size (annotate: can obtain accurate battery discharge total amount, the self discharge electric weight is equivalent to the total electric weight of charging to be reduced) of battery charge total amount.This algorithm only discharging fully immediately after the charging fully, can upgrade total charge value in addition.If the number of times that in battery lifetime, discharges fully seldom, before the electric quantity monitoring meter upgraded the actual electrical value, the true capacity of battery possibly begin to decline to a great extent so.This can cause the monitoring meter in these cycles, available power to be made too high estimation.Even battery electric quantity has carried out up-to-date renewal under to the fixed temperature and the velocity of discharge, available power still can change with the change of the velocity of discharge and temperature.Need revise the total electric weight of battery charge for this reason.Correction to the battery electric quantity total amount can have several different methods: the method for fuzzy neural network, open circuit voltage monitoring method etc., adopt more common succinct monitoring method at this: the open circuit voltage monitoring method carries out the correction of battery charge electric weight.
Battery voltage monitoring, this method is based on there being accurate correlation between cell voltage and the dump energy.But only under the situation that does not apply any load, just there be simple related between this cell voltage and the electric weight in this method during measuring.When applying load (it is in most cases interested to electric weight that this situation occurs in the user), cell voltage will produce distortion because of the caused pressure drop of internal battery impedance.In addition, even removed load, occur in opening of inside battery and hold process also can cause voltage in several hours continuous variation.So be under the situation of relaxation state with power supply non-loaded, this method can realize accurate battery dump energy estimation.In addition, this method also makes and has an opportunity to utilize not duty cycle (any battery-powered equipment all can have not duty cycle) to seek battery dump energy definite " original position ".Because equipment can be known accurate battery dump energy when connecting, so this method has been exempted the demand of self discharge being proofreaied and correct in duty cycle not.When applying load, then transfer to use the current integration method, can calculate battery dump energy accurately when equipment entering operating state and to battery.
The management of charging and discharging module:
1) external power source and battery powered automatic switchover.When no external power supply, adopt the internal battery power supply automatically; When connecting external power source, automatically switch to external power source system is supplied power, isolate battery pack battery pack is discharged and recharged operation.
2) the online voltage stabilizing of voltage, rectification.When externally power supply was supplied power, there was bigger fluctuation in external power source voltage, possibly cause the instability of system, and the mode that for this reason adopts online voltage stabilizing to isolate is carried out voltage stabilizing, the filtering operation raising stability of a system and life-span to supply power voltage, electric current; When battery-powered, there is floating charge, the battery voltage situation with the fluctuation of load (battery voltage fluctuation) in battery, influences system stability, and the battery Voltage stabilizing module is provided for this reason, guarantees that battery pack provides a constant reliable work voltage.
3) provide and discharge and recharge overload protection.
Battery pack overvoltage, under-voltage protection thresholding are provided.When voltage fluctuation excessive (outside the setting range), cut off powered battery when battery voltage is on the low side (being lower than setting voltage value) automatically.Promptly unstable when power supply, can the assurance system not work when power supply is under-voltage, prolong lifetime of system.
