Like Fig. 3 is the circuit theory diagrams of the utility model, and showing among the figure has enabling signal circuit, single chip circuit, plastic drive circuit, controlled electronic switch; Polar protective circuit, DC power supply circuit and battery.
When prosthetic appliance was worked, (for improving certainty of measurement, this device adopted four-wire system to binding post CON1; During wiring, 1,2 pin of binding post CON1 link to each other in the positive terminal short circuit of battery 7, and 3,4 pin of CON1 link to each other in the post short circuit of battery 7 negative poles) correctly be connected to and repaired the battery two ends; Diode D1 positively biased conducting in the polar protective circuit; Cell voltage makes the V2 conducting through R9, R10 dividing potential drop, and relay K 1 coil gets electric, the closing of contact; It is electric that controlled electronic switch is got, and voltage is added to controlled controlled electronic switch V3 drain electrode; Simultaneously; The A/D2 port of single-chip microcomputer U1 detects cell voltage;,, after the paraphase amplification and acceleration and shaping of plastic drive circuit, supply with controlled electronic switch 4 and drive through PWM1 pin output control pulse by single-chip microcomputer U1; The continuous conducting of control switch pipe V3 with end, make the direct current of constant voltage and current limiting Switching Power Supply 6A become in check pulse current and be added to the two ends of being repaired storage battery 7.But sending of this in check pulse receives single-chip microcomputer U1 and start-up circuit 1 control, takes turns, intermittently sends.When the user presses the button START of start-up circuit or receives the enabling signal of the prosthetic appliance in front; The START IN pin of single-chip microcomputer U1 becomes low level by high level; Begin startup work, export high level simultaneously and light light-emitting diode D6, indication work at present state.
If the battery virtual voltage is lower than the float charge voltage of setting, it is 120uS that single-chip microcomputer U1 exports a string cycle through the PWM1 pin, and duty ratio is that 95% control impuls offers the triode V1 in the plastic drive circuit 3; Export high level simultaneously, make diode D4 light indicating operating status.If battery 7 virtual voltages are higher than the float charge voltage of setting, then export high level diode D5 is lighted, constant but pulse that width reduces of single-chip microcomputer U1 output cycle simultaneously, the every rising 0.02V of cell voltage does a stepping.Minimum duty cycle reduces to 5%; If this moment, battery terminal voltage also continued to rise when surpassing ceiling voltage 2.45V/ list lattice, the PWM1 pin of single-chip microcomputer U1 stops output, and controlled electronic switch 4 turn-offs; The battery two ends that do not have pulse current to be added to be repaired, battery terminal voltage falls after rise.The single-chip microcomputer U1 of every prosthetic appliance is behind timing one-period (for example 500MS); Pulse output is turn-offed in the capital; START OUT pin output high level is lighted the LED (not shown) in the photoelectrical coupler U6 simultaneously; Make the START IN pin of next prosthetic appliance single-chip microcomputer U1 become low level, trigger prosthetic appliance automatically and go round and begin again and take turns to operate by high level.
Present embodiment is through using, and effect is following:
1, with existing small-pulse effect electric current prosthetic device relatively because this installs the single chip circuit U2 that with good grounds cell voltage and ambient temperature are regulated control reparation pulse current automatically,, reach 0.1%~0.5%C so that its inceptive impulse electric current can be chosen is very big
10(C
10Nominal capacity for battery 10 hour rate currents discharges) even bigger, can quicken the maintenance process.The lead sulfate crystallization that 200Ah ~ 1000Ah only need just can remove clean inside battery in 48 hours to 168 hours.And existing little current impulse prosthetic device; Because will take the later stage into account overcharges to the influence of battery; Its pulse current is generally chosen very little, with the small-pulse effect electric current battery is repaired from start to finish, and remediation efficiency obviously reduces; The lead acid accumulator of same capability often needs just can embody effect more than three months;
Though 2, the utility model has increased pulse maintenance electric current; But under the control of enabling signal transmission circuit 1; No matter whole ups system has installed the online prosthetic appliance of how many platforms; In the unit interval, has only a prosthetic appliance in work, the pulse ripple interference problem that this has brought when having significantly reduced the instrument synchronous working.Make ups system after a kind of lead-acid batteries remote online of big capacity prosthetic appliance is installed, work that can be safe and reliable.
