Technical field

Belong to electronic technology field.

Background technology

This enterprise has applied for security personnel's product line for the previous period, and this product have to reserce cell, otherwise when without city During electricity, protection function will become a kind of illusory, and the when of without civil power, when being probably the peak that security personnel's accident occurs the most again Wait.So reserce cell is required.And the performance of reserce cell is directly connected to the performance of entirety.

But reserce cell is necessarily to its charge maintenance, the scientific maintenance to reserce cell, it is directly connected to backup electricity The life-span in pond, with capacity.Having data to think, battery is often not to be damaged, but charges improper and damage.In security personnel's equipment Battery, belong to reserve battery, volume capacity had particular/special requirement, be equipped with and make excessive demands in common product.The most how to ensure backup 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 that its internal charging controls, as opened Closing audion etc. to be easily damaged, it produces fault and accounts for the fault rate ratio of whole equipment very greatly, if therefore this pipe infringement, causes Complete machine can not use.Therefore these seem common technical problem, but become the serious major issue affecting a product quality.

Because above-mentioned reason, for ensureing the performance of this enterprise apllied security personnel product, the live part of this enterprise can not Use the common charging method to battery and common charging circuit.

The charging method of its routine is to use single DC charging method, and such method all can make electrolyte persistently produce hydrogen Carrier of oxygen, its oxygen, under internal high pressure effect, infiltrates into negative pole and generates CDO with cadmium plate effect, cause under pole plate available capacity Fall.If employing pulse charge, and use the method filled with stop and deposit, i.e. fill certain time, such as 5 seconds, just stop a timing Between such as 1 second.Major part is reduced into electrolyte under discharge pulse by the oxygen that so charging process produces, and can make gassing rate It is substantially reduced, reduces gassing rate and concentration polarization and ohmic polarization can be made naturally to be eliminated, thus alleviate plumbic acid Accumulator intrinsic pressure, makes the pulse charge of next stage more successfully carry out, so that lead-acid accumulator can absorb more Electricity.Intermittent pulse makes lead-acid accumulator have more sufficient chemical time, thus decreases plumbic acid in charging process and store The gassing rate of battery, the charging current that improve lead-acid accumulator can accept ability.Pulse charging method charging certain time was such as 5 seconds Clock, stops certain time such as 1 second, so circulates.This charging method can make lead-acid accumulator be produced in charging process Oxygen and hydrogen stopping under charging pulse, oxygen and hydrogen that major part separates out have been reduced into again electrolyte, and this is not only Decrease lead-acid accumulator gassing rate produced by the electrolysis of internal electrochemistry side reaction water in charging process, and right Seriously polarize and cause the lead-acid accumulator of inefficacy to also have repair, store using this charging method plumbic acid to losing efficacy After the certain number of times of battery charging and discharging, the capacity of lead-acid accumulator can be made gradually to recover.Not only according to data introduction by charging not only but also stop The charging method filled, not only helpful to lead battery, and some alkaline cells are also helped positively.

But by above-mentioned charging method, also there are technological difficulties, because the circuit of routine is the most or not conventional circuit Being the circuit filling not only but also stopping, its on-off control pipe is all the emphasis of fault, if allowing switching tube be in the state of pulse, it is easier to Becoming the probability of infringement, this is one, and it two is because circuit and has the control filled, and has again the control stopping filling part, therefore damages Position add again one times, if therefore by traditional design, must complex circuit, newly increased trouble point, how to have solved These contradictions, become new difficult point.

Along with enriching of the modern life, get more and more by the kind of the electrical equipment of battery, the security personnel studied except this enterprise Outside equipment, the most a lot of products, such as digital machine machine, mobile phone, etc., the requirement of its charger, also there is this enterprise requirements similar Place, so the research to charger, not only involves the quality of charger itself, also involves and be electrically charged asking of two aspects in pond Topic.Because a little good charging measures have positive meaning.

Further illustrate:

1, operation principle explanation.

After opening power supply, all unit are started working, wherein charhing unit to be electrically charged pond carried out charging work until Terminate.The feature one of charging is charging in a pulsed fashion, and two is within a cycle of pulse, the oriented charging being electrically charged pond Process, also has the process stopping filling, but the time of charging is more than the charging process stopping filling.So overall physical process is to fill Electricity.

Although it should be noted in charhing unit charging operating circuit and charging fallback circuit to be electrically charged pond constitute or Door power supply mode, but by the particularity of design measure, the most only charging work power on circuitry work, and the fallback circuit that charges Being in open-circuit condition, but once charging operating circuit damages, charging fallback circuit will automatically engage energising work.

In charging process, because during the work of ring oscillation formula impulse generating unit, ring oscillation formula impulse generating unit By charge display control interface unit, constantly make two controllable silicons in charhing unit be in and open and off-state, so What charge circuit produced is pulse current.

In the charging interval more than the charge rule of dwell time it is, within a cycle of pulse, when interface controllable silicon (figure In 2 6.1) cut-off time, charhing unit is open-minded, to be electrically charged pond charging, when interface controllable silicon is opened, charhing unit close, Stop charging.Owing to, within a cycle of pulse, the time of charging is long, and the time stopped is short, so charging process is place In pulse charge state.Such charging modes is conducive to the scientific maintenance to battery, the battery damaged also is had one simultaneously Determine the restitution of degree.

When being electrically charged pond and being not in contact with, the battery terminal contact instruction lamp in battery terminal contact display branch road is (in Fig. 2 16.3) do not work, because the electric current of this part instruction is not when plugging alternating current, be derived only from battery.Now, user will be indicated Should clip and be electrically charged pond.

When being electrically charged cell voltage and not putting in place because charhing unit conducting charging, when be electrically charged pond charging put in place after because Outfan output of charging is high-order, has arrived the transfer valve of end shaping amplifying unit because terminating starting adjustable valve value cell output voltage Value, preposition shaping amplifier (in Fig. 2 14.1) exports anti-phase, and the second shaping amplifier (in Fig. 2 14.2) still keeps high-order, Now terminate controllable silicon (in Fig. 2 14.3) to be triggered, thus clamper charging control point, make charhing unit open circuit.Finishing control Diode (in Fig. 2 14.5) excitation charge display, makes charge display be output as low level, so that control of discharge point is without height Pressure, is also switched off charhing unit, and controllable silicon discharge cell also quits work and becomes open-circuit condition, thus whole circuit is closed.

The most connected trickle resistance (in Fig. 2 2.1) is to the tiny stream electric current of the maintenance being electrically charged needed for pond provides.

2, line feature analysis.

(1), terminate to start adjustable valve value cell, the explanation of end shaping amplifying unit.

Wherein: terminate to start adjustable valve value cell by starting protection partially in adjustable inclined resistance (in Fig. 2 13.2), starting Inclined resistance composition (in Fig. 2 13.3) under resistance (in Fig. 2 13.1), starting；Terminate shaping amplifying unit to be put by preposition shaping Big device (in Fig. 2 14.1), the second shaping amplifier (in Fig. 2 14.3), feedback circuit, end controllable silicon are (in Fig. 2 14.3), finishing control diode (in Fig. 2 14.5) composition:

Feedback circuit is by Derivative Feedback electric capacity (in Fig. 2 14.6), feedback diode (in Fig. 2 14.7), discharge resistance (in Fig. 2 14.8) form.

This unit is selected two key benefit making preposition shaping amplifier and the second shaping amplifier respectively have two, one Be the door with ring oscillation formula impulse generating unit be a kind of model, it is simple to produce.Two is the threshold values that door has upset, once exceeding Threshold values, door just overturns, and after three are two series connection, have and amplifies shaping operation further, further shorten the switching process of door.Cause And have good performance.Start adjustable inclined resistance (in Fig. 2 13.2) and sampling voltage can be adjusted neatly, again because connecting Start upper inclined protective resistance (in Fig. 2 13.1), so excessive deviation will not be produced in debugging process.Due to such electricity Road, threshold values is obvious, has again two amplifications connected, so there being the highest sensitivity.And the effect of feedback circuit is when knot Do up dynamic adjustable valve value cell and just arrived threshold values, accelerate to terminate the startup of shaping amplifying unit, thus proceed-to-send effect is brighter Aobvious.

When terminating shaping amplifying unit and having high-order output, a high position is passed to by finishing control diode (in Fig. 2 14.5) The input of vibration three, thus allow vibration stop, high position transmission is also given charge display by finishing control diode simultaneously (in Fig. 2 8.0), institute is so that controllable silicon discharge cell stops without pumping signal, the work of discharge portion.Terminate controllable silicon (Fig. 2 In 14.3) clamper charging control point, in making charhing unit, two silicon controlleds control extremely low level, become cut-off, stop charging. Now, only trickle resistance (in Fig. 2 2.1) is to the tiny stream electric current of the maintenance being electrically charged needed for pond provides.

(2), interface unit.

This unit is by by interface controllable silicon (in Fig. 2 6.1) and interface controllable silicon negative electrode diode (in Fig. 2 6.2) group Become.

The control pole of interface controllable silicon (in Fig. 2 6.1) is by the control of charge display (in Fig. 2 8.0), and interface is controlled The anode direct clamper charging control point of silicon.

Thus interface controllable silicon mainly has two big functions,

One is the AC charging logic producing charhing unit.Its reason is under the excitation of ring oscillation formula pulse unit, Control this interface controllable silicon through charge display (in Fig. 2 8.0), make interface silicon controlled anode produce high Yu low pulse Change, so that two silicon controlleds control the pulse change of pole generation height in charhing unit.When interface silicon controlled anode is Time high-order, in charhing unit, two silicon controlleds control poles and are activated, for saturated opening state, on the contrary interface controllable silicon colelctor electrode During for low level, in charhing unit, two silicon controlleds control poles are clamped, and in charhing unit, two controllable silicons are cut-off off state, from And make the output of charhing unit produce the change of height shape.Whole charging process is made to become pulse charge shape.

Two is the extension realizing voltage and current relationship, because this circuit can be used for higher being electrically charged pond and relatively high power Battery charging, its charging voltage may be 12 volts and be such as 24 volts, and the highest voltage could possibly be higher than normal integrated circuit and bears Voltage, simultaneously when being electrically charged pond and being Large Copacity, the silicon controlled of live part controls electrode current may be the biggest, it is possible to By extending after interface controllable silicon, and unfettered.

(3), charging display unit.

This unit is made up of charge display (in Fig. 2 8.0), charging display branch road.

Charging display route charging display protective resistance (in Fig. 2 8.1) is gone here and there with charging indicator light (in Fig. 2 8.2) Connection forms.

When ring oscillation formula impulse generating unit works, charging display controller height Changing Pattern and ring oscillation formula The rule of impulse generating unit is identical, thus encourages charging indicator light to show, when charging terminates, terminates the output of shaping amplifying unit A high position, causes charging display controller to be output as low level.Charging indicator light not excited target, thus the most luminous.

(4), impulse generating unit.

Ring oscillation formula impulse generating unit is by three doors, oscillating capacitance, charge and discharge branch road, charging paths, ring resistance group Become.

Charge and discharge is propped up route frequency adjustable resistance (in Fig. 2 7.4) and is in series with frequency limitation resistance (in Fig. 2 7.5), Charging paths is empty than limiting resistance (in Fig. 2 7.8), dutycycle adjustable resistance (figure by steering diode (in Fig. 2 7.6), point In 2 7.7) it is in series.

The feature of this unit is a clapp oscillator, has frequency and adjusts, adjust with dutycycle in this circuit.

Impulse generating unit.Having 3 effects in the present invention, one is by interface SCR control charhing unit, makes to fill The form of electricity becomes the form of pulse charge.Two is to control controllable silicon discharge cell by charge display, makes charging overall process In, it is achieved the complex form that charging limit, limit is stopped.Three is the regulation realizing dutycycle.Make the overall process of charging, charge again in realization With stop the recombination process that fills, remain optimal allocation proportion.

A, oscillating capacitance and charge and discharge branch road define the coarse adjustment of frequency of oscillation.

Its reason is by vibration one (in Fig. 2 7.1), vibration two (in Fig. 2 7.2), vibrates three (in Fig. 2 7.3) constitute a ring oscillator with above-mentioned circuit, and charge and discharge branch road ratio therein has steering diode (in Fig. 2 7.6) The charging paths resistance of composition is much bigger, so the frequency of ring oscillator is mainly determined by charge and discharge branch road, adjusts the electricity of this branch road Resistance resistance adjustment, just can substantially determine the frequency of this agitator, (because accurately frequency further depend on dutycycle i.e. with Charging paths is relevant).The minimum resistance of the frequency limitation impedance versus frequency adjustable resistance of charge and discharge branch road has played limit value effect.

The oscillation principle that ring oscillator is formed is, when the outfan of vibrate (in Fig. 2 7.1) is high-order, shakes The outfan swinging two (in Fig. 2 7.2) is low level, is open circuit without oscillating capacitance (in Fig. 2 7.9), then because of charge and discharge The existence of branch road, the input of vibrate three (in Fig. 2 7.3) should be low.But because there being the existence of oscillating capacitance, it is impossible to jump Become, directly a high position has been passed to the input of vibration three, so the input of vibration three is in the charging process of electric capacity, become For a high position.At this moment the vibration outfan of three is low, and the outfan of of causing vibrating continues as height, and this state lasts till Oscillating capacitance charging terminates, and is split into the first half cycle of vibration, and after first half cycle terminates, three gate output terminal fusions of vibrating are low, lead It is high-order for causing vibration two gate output terminals, therefore forms the reciprocal electric discharge of oscillating capacitance, forms the later half cycle of vibration.

B, that this unit of the present invention is designed with dutycycle is adjustable.

The meaning of dutycycle be pulse within a cycle, the ratio of high bit time and low bit time.

Dutycycle adjustable line is mainly collectively constituted with charging paths by oscillating capacitance.

Forming adjustable principle is: when the gate output terminal that vibrates is for time high-order, and this high-order output end current is through vibration Electric capacity charge and discharge branch road and the parallel branch of charging paths, the then low level outfan of flow direction oscillation two, due to charging paths string The resistance of connection bigger less than charge and discharge branch road, so having the charging current of charging paths is leading composition.Regulate this branch road can Adjust, dutycycle can be regulated further.Duty-cycle limit resistance (in Fig. 2 7.8) in this is to dutycycle adjustable resistance The restriction of (in Fig. 2 7.7) minima.After oscillating capacitance charging terminates, when the outfan of two of vibrate be a high position, vibration two The high-order outfan of door makees reciprocal electric discharge by the parallel branch of charge and discharge branch road Yu charging paths to oscillating capacitance, due to two In branch road, charging paths has the existence of steering diode, and its reverse bias is infinitely great, so the main branch road of electric discharge is charge and discharge Branch road.It should be noted that, owing to the output of this unit is after interface controllable silicon is anti-phase, two that control charhing unit controlled Silicon, the charging interval is the shortest, then the time that charhing unit is opened is the longest, so the dutycycle of this unit is adjustable is built up in charging Road, and it is not built up in a major reason of charge-discharge circuit.When such situation implements to charge battery, at one of pulse The time in cycle time being charging interval length and stop filling is short, and on the whole to being electrically charged the situation that pond formation is charging.

Due to impulse generating unit, to have frequency-adjustable adjustable with dutycycle, so the charging to being electrically charged pond can realize Relative maximum is scientific.

C, the impulse generating unit logical relation to live part Yu discharge portion.

The input of charge display is equal to the output being connected to vibration two (in Fig. 2 7.2), makes charge display The output of (in Fig. 2 8.0) produces the conversion that height is different along with vibration, when charge display is output as a high position, connects The anode of mouth controllable silicon (in Fig. 2 6.1) is low level, thus the controllable silicon in clamper charhing unit, so charhing unit is disconnected Road, stops being electrically charged pond charging.

Otherwise, when impulse generating unit overturns, when making charge display be output as low level, interface controllable silicon anode is high Position output, the controlled electrode resistance of controllable silicon in charhing unit triggers, and charhing unit turns on, and is charged being electrically charged pond.

(5), automatic switching diode, work controllable silicon and backup silicon controlled feature and explanation.

A, to silicon controlled innovation with realize controllable silicon open circuit control pole control.

The internal structure of one-way SCR is as it is shown on figure 3, its inside is equivalent to a NPN audion and a PNP tri- The combination of pole pipe, its principle triggered is, when internal NPN transistor base has the forward bias of triggering, its colelctor electrode produces Raw amplification electric current, this electric current is again the base current of PNP triode, and the collector current that this pipe amplifies becomes PNP tri-pole The base current of pipe, thus it has been split into strong positive feedback.

The controllable silicon of innovation is to have connected diode at its negative electrode, thus improves the forward bias voltage of NPN audion, Last diode cathode connected becomes innovation silicon controlled vacation negative electrode, therefore when the base stage of NPN audion is with false Negative electrode short circuit, because forward bias increases, then the base current appearance direct short-circuit of NPN pipe is to ground, and need not be by inside PN joint produces transistor effect.So such benefit is, to saturated controllable silicon, as long as the current potential controlling pole negative electrode is less than False negative electrode, can be achieved with the cut-off of saturated controllable silicon, without using the way reducing anode current introduced in teaching.

That is to say that controllable silicon i.e. has controllable silicon and easily triggers saturated character, has again control control with after innovation controllable silicon Pole processed and reach the character allowing it end.This character also obtains testing sufficiently confirmation.

B, the perishable problem generally existed with the charhing unit solution existing product of the present invention.

The charhing unit measure of the present invention is mainly made up of several parts.Part I is work controllable silicon (in Fig. 2 3), Part II is backup controllable silicon (in Fig. 2 4), and Part III is the automatic switching diode (in Fig. 2 5) that charges, this unit Formed by a diode element, although this unit element is few, but under coordinating with backup silicon controlled, play particularly significant Effect, Part IV is trickle resistance (in Fig. 2 2.1) and control electrode resistance (in Fig. 2 2.2), the effect of trickle resistance Be be electrically charged pond charging terminate after, formed maintain trickle, control electrode resistance be trigger action, Part V be charging controlled Silicon negative electrode series diode (in Fig. 2 3.9), its effect is to make the controllable silicon in live part reliably to end.

Above-mentioned a few part most important core in the present invention.Its reason present invention devises three lists of such form Unit coordinates, and the work controllable silicon that can make at the very start of charging can be made to be in normal operating switch duty, and back up controlled Silicon unit is then in " resting state " of open circuit, damages once the controllable silicon that works and quits work, and backup controllable silicon will automatically Devote oneself to work, be therefore greatly improved the life-span of charger.

Tool maintenance statistics, for performing Push And Release during fragile elements is exactly this charge circuit in all of charger Audion.So the present invention has carried out emphasis process to this point, " in parallel " special with two controllable silicons and the side sealed up a door Formula, as the live part element of the present invention, after measure of the present invention is implemented, defines such operation principle, due to controllable silicon It is about 1 volt when saturated, (silicon controlled saturation voltage is more than saturated audion).Work controllable silicon is automatic because of non-serial connection charge Switching diode and outwards export, and back up controllable silicon last output because the automatic switching diode of charging of having connected is only, therefore Once two pipes have output simultaneously, must be work silicon controlled output voltage will be above back up silicon controlled finally export.This Time situation be that the diode in automatic switching diode that charges inherently becomes reverse bias, and sealed up a door and without output.I.e. Be backup controllable silicon without output electric current, thus do not produce power output, do not produce electrical wear, essentially without damage, and be referred to as " backup controllable silicon ", also becomes a kind of special standby replacement controllable silicon, as long as work controllable silicon is in running order, and backup Controllable silicon is at " dormancy " state.Under normal circumstances, charging tasks is only completed by work controllable silicon.In the present invention, work is worked as After making controllable silicon damage, no current exports, and now backup controllable silicon is because losing voltage of sealing up a door, and the most outwards exports electric current, it is achieved Normal automatic switchover.Therefore charger will not be scrapped.Thus greatly increase the reliability of charger.

2 points additionally should be described, one is owing to the most active part such as silicon controlled life-span is the highest, but active part Production process itself, and charger on the make reason to aspects such as the welding of active part, or the most not Work as factor, usually make active part such life-span be challenged, do not reach such requirement, and such automatically change work earnestly Make, it is simply that the one that this active part is not reached the high life makes up.Two is owing to two controllable silicon parameters are consistent, during work is all It is in the on off state opened Yu disconnect, so either charging controllable silicon work, or backup controllable silicon work, so whole Individual charging will not change.Three be use a controllable silicon (the backup controllable silicon in the present invention) be dormancy shape, the merit of this pipe Rate consumption is approximately zero, and electronic active part life-span and its power consumed have the biggest relation, so being hardly damaged, and compare Simple parallel relationship is used to connect functional reliability with two active parts much better.

The automatic switching diode that charges is that only one of which diode is formed, and its benefit is after work controllable silicon damages, Can automatically switch to back up scr promoter, and produced by it, pressure drop only has 0.7V, will not lose too much pressure drop.

When checking that there is no current on this road, ammeter can be connected in this road.

The present invention has a prominent advantage after implementing:

1, being to substantially increase the life-span of charger by the present invention one, decrease the scrappage of charger, two is to being filled Battery achieves science charging, enhances maintenance, extends the life-span being electrically charged pond, decrease scrappage.And both products, Either chargeable battery, or supporting charger, be all the commonly used kind of the modern life, so two kinds of products can be strengthened Environmental protection.Environmental protection is without minor matter, so the present invention has positive effect.

2, also there is important economic worth, for the value of common electronic product, such as this series products of charger, do not having Having under famous and precious first material, so first is Value of Science & Technology, second is manually to add expense, and the 3rd is only the cost of element, and this Bright increased element is limited.After the present invention implements, can be clearly felt that one is charger life-time dilatation after user, two are Being electrically charged pond life, three is that capacity will not occur significant change, and therefore society is bound to accept, and recognizes its scientific value, The most this excellent product can replace the product of inferior quality.Owing to, in the modern life, this product purpose is extremely widespread, so can produce Significantly economic worth.

3, using the charged form filling not only but also stopping, have significant maintenance effects to being electrically charged pond, some critics claim on the net can Rechargable battery is filled bad rather than is damaged, and this measure can be closed and to be electrically charged the maximum scientific maintenance that the charging in pond is relative, special It is not to acid battery.And by such charging and discharging mode, the capacity of battery and life-span can not only be made to reduce, even make Defective cell can obtain a certain degree of recovery, so meaning is the biggest.

4, excellent performance of the present invention, one is to charge and the ratio of stopping between the time of filling is the most adjustable, i.e. to being electrically charged pond Being that dutycycle is adjustable, two is the frequency-adjustable to pulse, and three is the most adjustable to being electrically charged pressure complete charge value, so from polygonal Degree stage construction, adapted to variety classes model is electrically charged pond model.In addition the present invention is not also afraid of and overcharges etc. advantage.

5 are connected with each unit science, and have accomplished comprehensive utilization, thus line circuit is simplified, reliability high.

6, easily produce, easily debug, be well suited for minuscule-type-enterprise and produce.

One, element is selected: three vibrations door, charge display, device shapings in ring oscillation formula impulse generating unit Integrated circuit 4069 all selected by amplifier, the second shaping amplifier, and this integrated circuit has 6 phase inverters, in charhing unit can The control unidirectional miniwatt silicon controlled rectifier of silicon, diode uses face bonded type diode, and oscillating capacitance uses electrodeless electric capacity, other resistance Hold part without particular/special requirement.

Two, making sheet, welding: make circuit control panel according to Fig. 2, and press the schematic diagram welding of map interlinking 2.

Three, energising checks and debugging.

1, energising inspection and the debugging to start element.

One fictitious load of welding replaces being electrically charged pond as shown in Figure 4.It is linked to be the simulation of adjustable stabilivolt with an audion Circuit, replacing being electrically charged pond becomes fictitious load.Rear title fictitious load.Connect with the voltage of circuit tester with charging outfan and ground Between.

Debugging fictitious load, allows the voltage gear in circuit tester be shown as different magnitude of voltage, such as 6 volts, and 12 volts, 18 volts, 24 volts.

Regulation start adjustable inclined resistance (in Fig. 2 13.2) value, make end shaping amplifying unit respectively 6 volts, 12 When volt, 18 volts of 24 volts of values, time all have 0 output, otherwise should exchange sample for and start upper inclined protective resistance (in Fig. 2 13.1) and starting The value of adjustable inclined resistance (in Fig. 2 13.2).

Supplemental instruction, is linked to be the principle of adjustable stabilivolt analog circuit with an audion, when the upper inclined resistance of this pipe When uprising, the voltage of charging end to increase the bias voltage that just can puncture this pipe, makes this pipe enter magnifying state, this fictitious load three The collector voltage of pole pipe has a scope changed, thus can be modeled to a different Zener diode, thus permissible Simulate 6 volts, 12 volts, the value of 18 volts 24 volts.

2, inspection and the debugging to the energising of impulse generating unit frequency.

Fictitious load in connection.Connect the outfan of ring oscillation formula impulse generating unit with oscillographic hot junction, i.e. vibrate The outfan of three, cold end ground connection.

After being powered up, the vibration figure that oscillograph has shows.

If showing incorrect, then it is probably element welding wrong, or is probably oscillating capacitance (in Fig. 2 7.9) quality Bad, serious drain.

Regulating frequency adjustable resistance resistance, makes the frequency shown by oscillograph meet design requirement, and its rule is that resistance is got over Greatly, frequency is the slowest, otherwise the fastest.

3, checking innovation silicon controlled energising, innovation controllable silicon is as shown in the 3-2 in Fig. 3.

A, to innovation silicon controlled inspection.

Energising, connects innovation silicon controlled vacation negative electrode with the red test pencil of circuit tester, and the voltage gear in circuit tester shows should electricity. Short circuit innovation SCR control pole (in Fig. 3 93) and innovation controllable silicon vacation negative electrode (in Fig. 3 96), now Ying Wu electricity.

If situation does not meets, then it is that line is made mistakes, and is probably the diode polarity weldering that controllable silicon negative electrode is connected Instead.

4, the energising of docking port controllable silicon checks and debugging.

A, by interface controllable silicon base stage shorted to earth, now this pipe collector should be high-order, surveys charhing unit with voltmeter In two silicon controlled negative electrodes have electricity, be otherwise that line is wrong.

B, will after interface controllable silicon base series resistor connect power supply, now this pipe collector should be low level, uses voltmeter Measure two silicon controlled negative electrode Ying Wu electricity in charhing unit, if situation is incorrect, be then probably line wrong.Or trigger electricity Hinder excessive.

5, inspection and the debugging to the energising of impulse generating unit frequency.

Fictitious load in connection.Connect the outfan of pulse generator with oscillographic hot junction, be i.e. the output of vibration three End, cold end ground connection.

After being powered up, oscillograph has vibration figure to show, wherein an important feature of waveform is, at pulse wave Within one cycle, its low bit time is long, and the time of a high position is short, if situation on the contrary, is that steering diode is (in Fig. 2 7.6) direction weldering is anti-.

The regulation adjustable resistance of dutycycle, makes the dutycycle shown by oscillograph meet design requirement, and its rule is adjustable electric Hindering the biggest, the high bit time within a cycle is the biggest.Otherwise resistance is the least, the high bit time within a cycle is more Short.

6, to live part two silicon controlled inspection and debugging.

(1), logical check.

Test job controllable silicon and backup silicon controlled negative electrode respectively.Method of testing: red with the voltmeter in circuit tester Test pencil connects this point, black meter pen ground connection.

A, live part and the logical check of discharge portion.

With power line connect perform audion base resistance, now interface silicon controlled current collection is the lowest, live part without Output voltage, checks respectively for discharge work controllable silicon and electric discharge backup silicon controlled two colelctor electrode, and now 2 should be low level.

B, be wired to vibrate the input of three with power supply, allows three charge display outfans of vibration simultaneously for low level, Now interface silicon controlled current collection is the most high-order, and live part has output voltage, checks respectively for discharge work controllable silicon and electric discharge Backup silicon controlled two colelctor electrode, now 2 should be high-order.

Above-mentioned 2 correctly illustrate that charhing unit and controllable silicon discharge cell duty are all correct, if incorrect, then It is that line is wrong.Can enter down after Zheng Que and walk inspection.

(2), work controllable silicon checks with backup silicon controlled automatic switchover.

Under normal work charged state, ammeter is connected on backup silicon controlled negative electrode and charging conversion two poles automatically Between the positive pole of pipe, now ammeter shows and is approximately zero.

Work silicon controlled negative electrode is disconnected, ammeter is connected on work silicon controlled negative electrode and charging controllable silicon negative electrode Between the positive pole of series diode, ammeter has electric current to show, represents that work controllable silicon is in duty.

Case above is the most incorrect, shows to connect wrong.

Short circuiting work silicon controlled controls pole and negative electrode, simulates work silicon controlled distress condition, and ammeter has electric current to refer to Show, represent that backup controllable silicon is devoted oneself to work state.As incorrect, show to connect wrong, or backup controllable silicon damages.

7, the inspection to display part.

A, the battery terminal contact in load unit is shown check and be electrically charged pond when installation, and when being not switched on power supply, battery Contact display lamp (in Fig. 2 16.3) Ying Liang, if incorrect, is probably battery terminal contact instruction lamp polarity weldering anti-, or battery connects Touch display protective resistance (in Fig. 2 16.2) resistance excessive.

B, the inspection that the process of filling is shown.

After energising, the state output terminal of charge display should be with three gate output terminal state approximations of vibrating, and the charging being linked to be refers to Show that lamp (in Fig. 2 8.2) is luminous in charging process, at the end of initial termination unit, should put out, as phenomenon is not inconsistent, be then charging The resistance of display protective resistance (in Fig. 2 8.1) is excessive, or charging indicator light damages.

8, the detection to tiny stream electric current.

Ammeter is connected on trickle resistance (in Fig. 2 2.1) branch road, debug tiny stream resistance, make tiny stream electric current in accordance with Requirement.Its rule is that resistance more small area analysis is the biggest.Otherwise the biggest electric current of resistance is the least.
