Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is microcontroller circuit theory diagram of the present invention;
Fig. 2 is simulation control part schematic block circuit diagram of the present invention.
Embodiment
As shown in the figure, Imaging Logging System DC power supply, it comprises two power supplys, output control relay circuit, tension measuring circuit, current measurement circuit, microprocessor, output control circuit and isolated amplifier circuit; The output port of described two power supplys connects the input port of output control relay circuit; The output port of described output control relay circuit connects the input port of tension measuring circuit and current measurement circuit successively; The output port of described tension measuring circuit and current measurement circuit connects the input port of microprocessor; The output port of described microprocessor controls through output the input port that potentiometer connects output control circuit; Described output control circuit output port joins through the input port of isolated amplifier circuit and two power supplys.Two power supplys of the present invention are DCS600-1.7E power supply.Microprocessor of the present invention comprises single-chip microcomputer, program storage, data storage, LCD display and address decoding circuitry; Described single-chip microcomputer adopts MC68HC11 chip.
The present invention is by microprocessor and analog circuit control technology, two DCS600-1.7E that Japanese SORENSEN company is produced control, meet the requirement of 5700 and 2000 pairs of DC power supply, the particularly requirement of 2000 system MRIL-P to " BOOST " function of DC power supply.
Shown in Figure 1, microcontroller circuit of the present invention is mainly by MC68HC11 single-chip microcomputer, the compositions such as program storage, data storage, LCD display, address decoding circuitry.MC68HC11 single-chip microcomputer has four input/output ports, and wherein PORTB is A8～A15 address interface; PORTC is multiplexing mouthful of address date: A0～A7/D0～D7; PORTA is that mouth is controlled in input and output, PA0 is defined as input control line, when PA0 is high level, microprocessor does not carry out lifting to power supply, when PA0 is low level, microprocessor is increased or is reduced 40VDC and calculates cable resistance by moment, thereby realizes the lifting of output voltage " BOOST " function.PA3～PA6 is defined as output control line, its be output as+5V or 0V, and PA3～PA6 carries out binary coding, can divide the amplitude of the every step 40VDC of 15 step to control the output of DC power supply, and the highest can lifting voltage be 600VDC.PORTE is 8 passage A/D input ports, with three A/D input ports (PE0, PE1, PE2) wherein, respectively the output valve of VD, electric current, potentiometer setting is sampled.
Shown in Figure 2, simulation output control part mainly contains the compositions such as two DCS600-1.7E power supplys, output control relay, output voltage measuring circuit, output current measuring circuit, output control circuit, isolated amplifier.
When for 5700 time, by the potentiometer of front panel, make potentiometer be output as 0～5V, give output control circuit, now because PA0 is 5V, microprocessor does not carry out lifting to voltage, now PA3～PA6 is 0V, the output of output control circuit is also 0～5V, give after isolated amplifier isolation amplification in 1: 1, two DCS600-1.7E are controlled, make the output of every at 0～600VDC, under the control of the band switch by front panel, output control relay is connected the output of two block power supplies, according to the position of band switch, deliver to respectively J1 or J2 output.
J1, J2 are 5700 uses, while needing J1 power supply, are put into J1 position.While needing J2 power supply, be put into J2 position.During 2000 use, be put into J3 position, for conventional instrument power supply, be put into NORM position.While surveying nuclear-magnetism, be put into MRIL position, start " BOOST " function.
Be understandably, above about specific descriptions of the present invention, only for being described, the present invention is not limited to the described technical scheme of the embodiment of the present invention, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the present invention, to reach identical technique effect; As long as meet, use needs, all within protection scope of the present invention.
