The power supply of external circuit and micro controller system and ground isolate fully, and input circuit is eliminated external disturbance through filtering, and signal logic serves as effectively with low resistance 0 level, and it is effective that the outside then constitutes loop with electric current, and external disturbance is suppressed.
1. analog input A/D translation circuit:
The native system analog input is mainly the current of electric monitoring, adopts electric current isolation sensor/transmitter that alternating current is converted to the 4-20MA signal and send micro controller system to convert through A/D.
Electric current isolation sensor/transmitter is seen accompanying drawing (3)
CT is a current transformer among the figure, and big electric current, high-tension motor lines by the input of CT perforation means, are isolated with external circuit, through the 4-20MA signal of current transformer, rectification, conditioning, V/I conversion outputting standard.Avoid system to be subjected to the interference of strong signal, thereby improve the reliability of system.
The 4-20MA output signal, current signal send microprocessor system through current/voltage conversion, A/D conversion.
2. the frequency division rectification is the design of pulsating direct current (ratio frequency modulation) drg direct supply arbitrarily:
The windlass dc electromagnetic brake belongs to the dead electricity braking, and the drg power requirement is as follows:
A. export two kinds of vdcs of 110-130V/20A and 27-35V/10A.
B. windlass control requirement, drg also can simultaneously quick brake off when the electrical motor energising began to rotate.
Braking power generally adopts 380V to exchange through the voltage transformer step-down at present, rectification output ripple vdc 110-130V and be controlled in the 110-130V Rectified alternating current hydraulic circuit mode that the step-down of polyphone high-power resistance obtains the 27-35V pulsating dc voltage with relay.Voltage transformer and resistance reactive loss are big, and drg opening time is between 300-500MS.
According to the drg power requirement, design-calculated ratio frequency modulation drg direct supply is seen accompanying drawing (4).
T is that electronic switch (solid-state relay) D2 (diode bridge) that photoelectricity isolation high-power zero voltage is closed, zero current is disconnected forms the zero-crossing detection circuit that exchanges the 380V power supply with photoelectric coupling circuit among the figure, zero cross signal is sent to micro controller system, micro controller system is sent the pulse wave control signal on the back edge of zero cross signal, produces the direct current pulse wave electric voltage that requires output.
Frequency modulation drg direct supply mode chart is seen accompanying drawing (5).
Different with traditional drg direct supply, this circuit adopts computer controlled, exchanges the 380V power supply after pulse wave control (modulation), and what obtain is that amplitude is constant, and fundamental frequency equals the AC signal of pulse wave control signal frequency.
Exchange the average voltage=380*0.9=342V of a pulse wave of 380V.
After the control of 1/3 pulse wave, the 50HZ frequency conversion is 50*2/3=33.3HZ, obtains the pulsating direct current that average voltage is 342/3=114V after rectification among the last figure; In like manner after the control of 1/11 pulse wave, the 50HZ frequency conversion is 50*2/11=9.1HZ, obtains the pulsating direct current that average voltage is 342/11=31V after rectification.Theoretically, circuit as calculated machine control can export direct current average voltage level arbitrarily.
The output voltage current characteristics that shows traditional drg direct supply and the design's power supply is relatively seen accompanying drawing (6).
That fine rule shows among the figure is traditional drg direct supply output voltage current waveform Va, ia, and that thick line shows is design-calculated drg direct supply output voltage current waveform Vb, ib.
The average voltage electric current of two kinds of drg power supply outputs equates, but the cranking voltage electric current of frequency modulation drg direct supply wants big 3-4 doubly, we know, the suction of drg electromagnet is directly proportional with electric current, is inversely proportional to drg starting instantaneous large-current with air gap, strengthen suction, air gap dwindles, and forms over excitation, the accelerated motion time.
The output voltage of ratio frequency modulation drg direct supply is by controlled by the pulse wave control signal, producing 110V voltage and export 30V after 0.5 second.
Pulse wave control signal period T (x):
110V voltage is produced by 1/3 pulse wave control signal, its cycle:
T(1/3)＝20ms?X?3/2＝30ms
110V voltage is controlled at about 0.5 second as requested,
0.5 second/T (1/3)=5000/30=17
Export 17 1/3 pulse wave control signals and both produced 0.5 second 110V pick-up voltage.
30V voltage is by 1/11 pulse wave control signal, its cycle:
T(1/11)＝20ms?X?11/2＝110ms
The forward position of pulse wave control signal is back along triggering by the zero crossing pulse, and pulsewidth requires greater than 10ms, less than 20ms, can not cover 2 zero crossing pulses.
3. motor-driven and variable speed control design:
Motor-drive circuit is seen accompanying drawing (7).
Only drawn among the figure driving circuit of a winding of motor, the driving circuit of three windings of three-speed motor is the same.The micro controller system control signal that casts anchor when casting anchor makes the left side three cover drive circuit works; The micro controller system control signal of weighing anchor when weighing anchor makes the right three cover drive circuit works, motor just/counter-rotating both reached/cast anchor work.
Beneficial effect is analyzed:
As following table:
1. the motor zero voltage is left, and zero current is disconnected, the over excitation of drg pulse wave starts, and makes startup, operation, braking steadily;
2. drg power supply energy consumption reduces significantly;
3. system's operation is impacted little to electrical network;
4. user-friendly for operation, intelligent, the system protection measure is perfect.
Windlass intelligent controller system is different with traditional windlass controller from structure, mode, motor-driven, technology that braking power adopted, from last table, find out, the windlass intelligent controller mainly in reliability, energy consumption, showed the advanced and creative of it on the life-span.
Because the windlass intelligent controller adopts computer technology, equipment self-inspection, prompting, alarm are complete, both need not train and can operate, use, except that machinery itself needs to safeguard on request, the windlass intelligent controller need not safeguarded substantially, as long as operate by the prompting of windlass intelligent controller.
Because what the windlass intelligent controller adopted is stored programme and network control technology, though the basic function that it is realized is identical with traditional windlass controller, function expansion is strong, also can be adapted to various windlass.
Tradition windlass controller is to single speed, double speed, the three fast windlass motor and the drgs of different capacity, circuit difference; And the windlass intelligent controller adopts is the stored programme control technology, and hardware circuit is identical, and software moves the corresponding apparatus drive program automatically according to different windlass motor and drg.
It is at the characteristic of inductive DC brake, and a kind of simple digital circuit processing method of proposition is a pulsating dc voltage with any frequency division of 50HZ alternating current, through practice, and the reliability height, energy-saving and cost-reducing.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
