Technical field

Belong to electronic technology technical field.

Background technology

This enterprise having applied for security personnel's product line for the previous period, and the product has to reserce cell, and otherwise when without civil power, protection function will be illusory as one kind, and be probably again exactly when there is the peak of security personnel's accident when without civil power.So reserce cell is required.And the performance of reserce cell is directly connected to overall performance.

But reserce cell necessarily to its charge maintenance, to the scientific maintenance of reserce cell, is directly connected to the life-span of reserce cell, with capacity.There is data to think, battery is often not what is damaged, but charge it is improper and damage.Battery in security personnel's equipment, belongs to reserve battery, there is particular/special requirement to volume capacity, and outfit is made excessive demands in common product.Therefore how to ensure that back-up battery life and unaffected this of capacity are one of problems.

The two of problem are tool repair information statistics, and to general charger, the active part of its internal charge control, such as switch triode is easily damaged, and the fault rate ratio that its generation failure accounts for whole equipment is very big, so if the pipe is damaged, causes whole machine to use.Therefore these seem common technical problem, but become one serious major issue of product quality of influence.

Because above-mentioned reason, to ensure the performance of the apllied security personnel's product of this enterprise, the live part of this enterprise can not be using the common charging method to battery and common charging circuit.

Its conventional charging method is that, using single DC charging method, such method can make electrolyte persistently produce hydrogen or oxygen gas, under the high pressure effect internally of its oxygen, infiltrates into negative pole and cadmium plate effect generation CdO, causes pole plate available capacity to decline.If using pulse charge, and using the method using filling with putting and deposit, that is, filling certain hour, such as 5 seconds, certain hour is just put such as 1 second.Major part is reduced into electrolyte by the oxygen that so charging process is produced under discharge pulse, can substantially reduce gassing rate, reducing gassing rate can make concentration polarization and ohmic polarization naturally be eliminated, so as to alleviate the internal pressure of lead-acid accumulator, making the pulse charge of next stage is more successfully carried out, so that lead-acid accumulator can absorb more electricity.Intermittent pulse makes lead-acid accumulator have more sufficient chemical time, so as to reduce the gassing rate of lead-acid accumulator in charging process, improves the acceptable ability of charging current of lead-acid accumulator.Pulse charging method charging certain hour such as 5 seconds, stops certain hour as discharged 1 second, so circulation.This charging method can make the produced oxygen in charging process of lead-acid accumulator and hydrogen in the case where charging pulse is stopped, the oxygen and hydrogen that major part is separated out have been reduced into electrolyte again, this not only reduces lead-acid accumulator in charging process internal electrochemistry side reaction --- the gassing rate produced by the electrolysis of water, and cause the lead-acid accumulator of failure to also have repair to seriously polarizing, after the certain number of times of lead-acid accumulator discharge and recharge using this charging method to failure, the capacity of lead-acid accumulator can be made gradually to recover.Pressed according to data introduction not only but also the charging methods of the double electric discharges of charging, or the method for stopping filling that charges, it is not only helpful to lead accumulator, and some alkaline cells are also helped positively.

But by above-mentioned charging method, conventional circuit is also the presence of technological difficulties, because the circuit of routine is not the circuit for filling but also putting not only, its switch control pipe is all the emphasis of failure, if allowing switching tube to be in the state of pulse, it is easier to the probability as infringement, this is one, the second is because circuit has the control filled, there is discharge portion again（Or stop filling）Control, therefore the position of infringement increased one times again, so if by traditional design, must complex circuit, newly increased trouble point, how to solve these contradictions, become new difficult point.

With enriching for the modern life, species with the electrical equipment of battery is more and more, in addition to security personnel's equipment that this enterprise is studied, also many products, such as digital machine machine, mobile phone, etc., the requirement of its charger, also there is the place of similar this enterprise requirements, so the research to charger, not only involves charger quality in itself, also involve and be electrically charged two, the pond problem of aspect.Because a little one good charging measures have positive meaning.

Further illustrate：

1st, operation principle explanation：

After opening power supply, all units are started working, wherein p-type charhing unit and N-type discharge cell, to the charging that pond charge more than the process of electric discharge is electrically charged, are terminated until charging.

It should be noted that charge circuit of awaiting orders of p-type charging operating circuit and p-type constitutes OR gate power supply mode to being electrically charged pond only in pipe p-type charhing unit, but by the particularity of design measure, usually only p-type charging work power on circuitry work, and p-type charges and awaits orders circuit in open-circuit condition, but once p-type charging operating circuit is damaged, charge circuit of awaiting orders of p-type will automatically engage energization work.

Similarly, it should be noted that electric discharge operating circuit and electric discharge circuit of awaiting orders constitute OR gate to being electrically charged pond and form discharge mode to being electrically charged pond only in pipe N-type discharge cell, but by the particularity of design measure, usually only electric discharge operating circuit energization work, and discharge and await orders circuit in open-circuit condition, but once electric discharge operating circuit is damaged, electric discharge circuit of awaiting orders will automatically engage energization work.

In charging process, because integrated form impulse generating unit works, constantly two pipes in control p-type charhing unit are in opening and off-state, so whole work process is the pulse current charge for using.

During pulse charge, the charging physical process of use is that charge and discharge coexists.Can also be by excision switch closure, only with the form of pulse charge, so as to increased flexible selectivity.

The charge rule coexisted in charge and discharge is, within a cycle of pulse, when being opened in p-type charhing unit, N-type discharge cell is closed.Otherwise when being closed in p-type charhing unit, N-type discharge cell is open-minded.Because within a cycle of pulse, the time of charging is long, and the time discharged is short, so whole charging process is in pulse charge state.Such charging modes are conducive to the scientific maintenance to battery, while the battery to having damaged also has a certain degree of restitution.

This measure, as terminating, when regularly when time is up, counter output output is high-order, produces following effect to exist using timing, and the first via passes through end trigger resistance（In Fig. 2 8.2）With end trigger diode（In Fig. 2 8.3）Series arm trigger the high threshold end of 555 integrated circuits, so as to cause 555 ic outputs for low level, make interface triode（In Fig. 2 5.1）Current collection is extremely high-order, thus two pipes in p-type charhing unit lose biasing, and turns into the open-circuit condition of cut-off, stops charging to being electrically charged pond.Second tunnel is high-order because counter output is exported, and thus results in end triode（In Fig. 2 8.1）Current collection extremely low level, electric discharge base stage control point makes discharge portion end two pipes in N-type discharge cell without bias current directly by the colelctor electrode clamper of end triode, thus stopped the discharge process to being electrically charged pond.3rd tunnel is that the current collection for terminating triode passes through clamp diode（In Fig. 2 8.5）The clamper vibration of counter, makes counter failure of oscillation and keeps existing state, until the beginning of next discharge and recharge.Now connected tiny stream current resistor provides the tiny stream electric current of required maintenance to pond is electrically charged.

2nd, line feature analysis：

（1）, interface unit.

The unit is by interface triode（In Fig. 2 5.1）, interface triode triggering resistance（In 2 5.3）, clamp diode one（In Fig. 2 5.2）Composition.

Interface triode mainly has five functional.

One is the pulse charge logic for producing p-type charhing unit.Its reason is under the excitation of integrated form impulse generating unit, by the transmission of the pipe, to make the pulse change of the base stage generation height of two pipes in p-type charhing unit.（When interface transistor collector is low level, p-type charhing unit is forward bias, is the state being powered, on the contrary interface transistor collector for it is high-order when, it, without biasing, is off state that p-type charhing unit is）So that the colelctor electrode of two pipes produces the change of height shape in p-type charhing unit.Whole charging process is set to turn into pulse charge shape.

Two is the clamp diode one being connected with interface triode（In Fig. 2 5.2）With the base stage all-in resistance in N-type discharge cell（In Fig. 2 9.1）Cooperation under, there is provided the pulse excitation electric current of N-type discharge cell.So as to produce the logic function of electric discharge.The largest benefit of this spline structure can be save one be necessary for N-type discharge cell needed for anti-phase triode.Thus make circuit more simplified.Its reason is that this anti-phase triode can not directly be served as by interface triode.If the base stage input of N-type discharge cell simply should be connected in into interface triode（In Fig. 2 5.1）On colelctor electrode, when interface transistor collector is for a high position, just there is shunt current to flow to the base stage of two triodes in N-type discharge cell.The ill-effect of generation is when p-type charhing unit should now be closed, because with the presence of shunting, p-type charhing unit is impossible to thoroughly closing.Become and fill double inconsistencies put.But have passed through clamp diode one（In Fig. 2 5.2）After isolation, the shunting needed for the base stage of two triodes for flowing into N-type discharge cell is not provided by the collector resistance of two pipes in p-type charhing unit, and is changed by clamp diode one（In Fig. 2 5.2）With base stage all-in resistance（In Fig. 2 9.1）Base stage all-in resistance in series arm is provided, with regard to thoroughly avoiding this problem.So an inverted logic triode can be reduced, but performance is without being affected.

Three is to become complete charge status switch pipe.A high position is upgraded to when cell voltage regularly when time is up, is electrically charged, counter output output is high-order, the end triode in finishing control unit（In Fig. 2 8.1）, export low level signal, 555 integrated circuits in clamper integrated form impulse generating unit（In Fig. 2 6.1）High threshold end, thus 555 integrated circuit output end output low level, encourage interface transistor base, cause interface transistor collector voltage for a high position, close two pipes in p-type charhing unit.

Four is the extension for realizing voltage and current relationship, because the circuit can be used for the battery charging for being electrically charged pond and relatively high power higher, its charging voltage may be for 12 volts as being 24 volts, voltage so high could possibly be higher than the voltage that 555 integrated circuits bear, simultaneously when pond is electrically charged for Large Copacity, the base current of two pipes may be very big in p-type charhing unit, it is possible to by that can be extended after mouth triode, and unfettered.

Five is to produce charging process display function.When interface transistor collector is low level, charging process luminous tube（In Fig. 2 2.2）Bright, charging, end current collection is extremely high-order, and charging process luminous tube does not work.

（2）, integrated form impulse generating unit.

The characteristics of unit is to be not only a clapp oscillator, and frequency and duty ratio adjusting circuit are also devised with the line.

Integrated form impulse generating unit.There are 3 points of effects in the present invention, one is by interface triode（In Fig. 2 5.1）Control control p-type charhing unit, and make the form of charging as the form of pulse charge.Two is to control N-type discharge cell by interface triode, and makeIn charging overall process, complex form of being discharged in charging is realized.Three is the regulation for realizing frequency and dutycycle.Make the overall process of charging, realizing the recombination process of charge and discharge again, remain optimal situation.

The unit is by 555 integrated circuits（In Fig. 2 6.1）, charging paths, discharge paths, integrating capacitor（In Fig. 2 6.6）Composition.

Charging paths are by charging adjustable resistance（In Fig. 2 6.2）With charge protection resistance（In Fig. 2 6.3）It is in series；Discharge paths are by electric discharge adjustable resistance（In Fig. 2 6.5）With discharge prevention resistance（In Fig. 2 6.4）It is in series.

Because the equivalent charging resistor of integrating capacitor is that charging paths are connected sum with discharge paths, so the charging interval is long, and discharge paths resistance is small, so the circuit and correlation unit of the present invention are matched very much, while can realize adjusting very well.

Forming the principle of vibration is, after energization, because integrating capacitor（In Fig. 2 6.6）Underfill electricity, so 555 integrated circuits（In Fig. 2 6.1）Power end by charging of the charging paths to integrating capacitor, low valve end is low level, the first half cycle as vibration.After the voltage of integrating capacitor is charged to the current potential of the threshold values at high threshold end, the discharge end output low level of 555 integrated circuits, integrating capacitor can only be by discharge paths to 555 IC interior discharge tubes（The discharge end of 555 integrated circuits）Electric discharge.In this measure, charge constant is big, and discharge time is small, so the time that 555 ic outputs are in a high position is long, by interface triode（In Fig. 2 5.1）It is anti-phase, cause the charging interval of live part long, and discharge portion discharge time is short, therefore meet that the charging interval in a cycle is long, and the logic that discharge time is short.Also because, charging adjustable resistance long to the integrating capacitor charging interval（In Fig. 2 6.2）It is related to frequency of oscillation, dutycycle is related to again, so charging adjustable resistance becomes " big to adjust ".Otherwise the electric discharge adjustable resistance of the discharge paths of integrating capacitor（In Fig. 2 6.5）Become " ditty " of frequency and dutycycle adjustment.Also because above-mentioned reason, can be by " big to adjust " and " ditty ", it is possible to which relative maximum scientific charge and discharge maintenance effect is realized in the charging to being electrically charged pond.

（3）, p-type charhing unit feature and explanation.

The main idea justice of A, the composition of p-type charhing unit and formation.

Tool maintenance statistics, for the triode that most fragile elements in all of charger are exactly execution Push And Release in this charge circuit.So having carried out emphasis treatment to the point in the present invention, the measure also becomes an important core of the invention.

P-type charhing unit by p-type charge operating circuit, p-type charge await orders circuit, compensation branch road（In Fig. 2 3.3）, trickle resistance（In Fig. 2 3.8）Composition.

P-type charging operating circuit is by PNP instrumentation tubes（In Fig. 2 3.11）, PNP instrumentation tubes base resistance（In Fig. 2 3.12）Composition；Charge circuit of awaiting orders of p-type is awaited orders pipe by PNP（In Fig. 2 3.21）, PNP awaits orders the base resistance of pipe（In Fig. 2 3.22）, isolating diode（In Fig. 2 3.13）Composition.

P-type charhing unit is a most important core in the present invention, its reason be the present invention devise such form can make p-type charging operating circuit from be powered at the very start all the time be in normal operating switch working condition, and p-type charges and awaits orders circuit then in " resting state " of open circuit, when p-type charging operating circuit is damaged and is stopped, charge circuit of awaiting orders of p-type will automatically engage work, therefore greatly improve the life-span of charger.

The reason for B, generation " work and alternation of backup formula ", is analyzed.

When PNP instrumentation tubes（In Fig. 2 3.11）After work conducting, because collection poling is exported by a high position, at this moment by isolating diode（In Fig. 2 3.13）It is connected to compensation branch road（In Fig. 2 3.3）Negative pole, cause the point for a high position.And compensate branch and route a voltage-stabiliser tube and formed with a Diode series, they become switching circuit again, are connected to PNP and await orders pipe（In Fig. 2 3.21）Base stage, so formed closure door.Its reason is that the await orders emitter stages of pipe of PNP have three PN to save to the point, and PNP instrumentation tubes（In Fig. 2 3.11）It is 0.2 volt after saturation, by, less than two PN sections, so PNP awaits orders, without bias current, no current, the state in idle are not produced electrical wear to pipe by its colelctor electrode after isolating diode.After PNP instrumentation tubes are damaged, colelctor electrode is without output, or exports weak, will not produce closure door, at this moment there will be bias current, causes PNP to await orders pipe when automatic switchover replaces PNP instrumentation tubes to work.

Should additionally illustrate at 2 points, one is because the life-span of triode in theory is very high, but triode production process in itself, and charger on the make to aspects such as the welding of triode the reason for, or improper factor in use, the life-span as usually making triode is challenged, and does not reach such requirement, and such automatic switchover work, exactly one kind that this triode does not reach the high life is made up.Two is, because two transistor parameters are consistent, the on off state opened with disconnect to be at during work, so the triode operation that either charges, or charging dormancy triode operation, whole charging will not change.Three is using a pipe（Charging dormancy triode in the present invention）It is dormancy shape, the power consumption of the pipe is approximately zero, and there is very big relation in the triode life-span with its power for being consumed, so be hardly damaged, and it is more much better than connecting functional reliability using simple parallel relationship with two pipes.

（4）, discharge portion the characteristics of explanation.

N-type discharge cell is by discharge resistance（In Fig. 2 9.6）, electric discharge base loop, excision switch（In Fig. 2 9.2）, electric discharge operating circuit, electric discharge change-over circuit, electric discharge await orders circuit composition.

Electric discharge base loop is by base stage all-in resistance（In Fig. 2 9.1）Formed：Electric discharge operating circuit is by electric discharge instrumentation tubes（In Fig. 2 9.31）With the base resistance of electric discharge instrumentation tubes（In Fig. 2 9.32）Composition；Electric discharge circuit of awaiting orders is awaited orders pipe by discharging（In Fig. 2 9.51）Awaited orders the base resistance of pipe with electric discharge（In Fig. 2 9.52）Composition；Electric discharge change-over circuit（In Fig. 2 9.4）Formed by several Diode series.

The meaning of N-type discharge cell has three, thus also becomes another core emphasis of the invention

One is that the function of being discharged again is in a cycle of pulse, when interface triode in the overall process for charging（In Fig. 2 5.1）During for a high position, when p-type charhing unit is in the halted state of open circuit, N-type discharge cell conducting now carries out spark to battery.Otherwise within a cycle of pulse, when p-type charhing unit is in the conduction state, N-type discharge cell herein is in breaking closed mode.It is that interface triode assume responsibility for such logic function to form such logical relation reason, while having played buffer action to two parts again.It is allowed to mutually be independent of each other.（Above interface triode unit is described in detail）.Pond state in filling but also putting not only in charging overall process is electrically charged, in the case where charge and discharge is proper, its benefit can be achieved on the maximum scientific of battery charging.Even can allow some battery performances be in it is very poor in the state of, a certain degree of recovery can be able to.

Two is N-type discharge cell because electric current is still larger in electric discharge, still employs electric discharge operating circuit and electric discharge and awaits orders the form that circuit coexists, in electric discharge instrumentation tubes（In Fig. 2 9.31）During electric discharge, due to the pipe of awaiting orders that discharges（In Fig. 2 9.51）Colelctor electrode because being in series with electric discharge change-over circuit（In Fig. 2 9.4）, threshold values is generated, so electric discharge is awaited orders, the collector current of pipe will be discharged the short circuit of work tube passage, and discharge and await orders pipe branch road then in currentless " resting state ", become a kind of standby pipe.When instrumentation tubes of discharging are damaged and during open circuit, electric discharge pipe branch road of awaiting orders automatically engages work, therefore greatly improves the life-span of discharge portion.

Three be discharge system base stage be connected with over the ground excision switch（In Fig. 2 9.2）, flexibility is increased, its reason is that discharge portion can only end without bias current after excision switch closure.

（5）, timing control unit.

The unit is by timer（In Fig. 2 7.1）Constituted with the peripheral oscillating circuit of timing.

The peripheral oscillating circuit of timing is by oscillating capacitance（In Fig. 2 7.5）, protective resistance（In Fig. 2 7.2）, oscillation resistance composition；And oscillation resistance is by vibration adjustable resistance（In Fig. 2 7.3）, vibration limiting resistance（In Fig. 2 7.4）Constitute a kind of frequency adjustment branch road.

The function of the unit mainly has three, and one is to providing pulse signal inside counter, to allow counter normal work.Two can be to be adjusted into line frequency, after its effect is cooperation with counter, the time that the charging interval terminates can be produced to adjust.Thus there is wide applicability to being electrically charged pond.

Three vibration ends of counter, respectively the 9th pin, the 10th pin, the 11st pin；Oscillating part composition inside counter is connected with door 2 by door 1, wherein output end the 9th pin of connection of door 2, the pin of input linkage counter the 11st of door 1, and the input of door 2 is connected 10 pin that a little connect with the output end of door 1.Produce vibration is with the principle of frequency-adjustable, and when the output end of door 2 inside counter is for a high position, the electric current of the output end of door 2 output inside counter can cross oscillating capacitance and frequency adjustment branch road flows to the output end of the door 1 inside counter.When oscillating capacitance is in original state, oscillating capacitance is unable to transition, so central connection point, it is electric capacity and the oscillation point of frequency adjustment branch road is a high position, thus the input of the door 1 inside counter is a high position, the output end of door 1 is low level, and this state turns into the first half cycle of vibration, and lasts till the threshold values of the upset of door 1.With increasing that oscillating capacitance charges, blocking situation is increased, the reduction of oscillation point voltage, and during 1 threshold values of door inside less than counter, the output end of door 1 is changed into high-order suddenly, and the output end of door 2 is changed into low level suddenly.So there is electric discharge in opposite direction to oscillating capacitance, its electric current is to adjust branch road through overfrequency from the output end of door 1, then by central point, then the output end that door 1 is flowed to by electric capacity.Form the later half cycle of vibration.It is additionally arranged the one-level voltage stabilizing to counter integrated circuit in the present invention, one is an adjustment point that the voltage can form threshold voltage the reason for important.

If the series value of two resistance of oscillation resistance is big, the time to oscillating capacitance charge or discharge is more long, then period of oscillation is more long.So form oscillation resistance resistance can turn into frequency-adjustable the reason for.That is to say the reason for cycle is adjustable.In frequency-adjustable branch road, fixed resistance is the limitation to frequency-adjustable resistance minimum value.

Another feature of this unit be oscillating capacitance employ two capacitances in series without polar form, the electric leakage of the larger electrochemical capacitor of capacity can thus be made becomes very little, thus vibration is very reliable does not stop polarization, relative frequency is accurate simultaneously, after coordinating with counter, timing is relatively accurate, to meet the requirement of mill run.

The function of counter is mainly as follows：One is after coordinating with peripheral oscillating unit, produce clocking capability, once timing terminates, end unit is issued instructions to, so as to close system correlation unit, stops the charging to battery, if now user does not take out and is electrically charged pond, will not overcharge, because oscillating unit has been stopped, pulse-free signal input.Frequency dividing is not produced.The frequency division output terminal of counter does not change.Two is that output end has high-order output when charging terminates, and power supply is provided to voice system, thus phonetic system can send sound instruction, notify user.Three is that the output end of counter can turn into being adjusted flexibly one of a little for time timing, to adapt to the battery of different model.

The unit characteristics one are that the length of timing has time range very wide after function reliability, with the cooperation of peripheral oscillating unit.Two is more accurate timing because present invention employs electrodeless electric capacity as oscillatory meter when fundamental oscillation element, electrodeless electric capacity has a leakage coefficient higher, therefore frequency is accurate, fully achieves the requirement of mill run accurate timing.Three is that timing frequency division output terminal can turn into one of adjustment point of time.Three is few peripheral element.The part is cheap simultaneously, workable.

（6）, end unit.

End unit is by end triode（In Fig. 2 8.1）, end trigger resistance（In Fig. 2 8.2）, end trigger diode（In Fig. 2 8.3）, terminate clamp diode（In Fig. 2 8.5）Composition：The end triode encouraged by the ultimate output end of counter（In Fig. 2 8.1）, mainly there are three big effects, one is that the high signal exported with the ultimate output end of counter triggers 555 collecting circuits（In Fig. 2 6.1）High threshold end, make interface triode（In Fig. 2 5.1）Current collection is extremely high, so as to hold termination live part to charge.Two is to use to terminate transistor collector low level signal clamper electric discharge base stage control point, so as to terminate to being electrically charged tank discharge work, three is, with transistor collector low level clamper oscillation point, to make counter failure of oscillation, will not produce overcharge conditions.

The present invention has the advantages that prominent after implementing：

1st, it is life-span for substantially increasing charger by the present invention one, reduces the scrappage of charger, two is to realize science to being electrically charged pond to charge, and enhances maintenance, extends the life-span for being electrically charged pond, reduces scrappage.And both products, either chargeable battery, or supporting charger, all it is the commonly used species of the modern life, so two kinds of environmental protection of product can be strengthened.Environmental protection without minor matter, so the present invention has positive effect.
