Described power supply and controller control to adjust each solenoidal plus, power-off time, the duty to solenoid work
The regulation of ratio, thus the regulation to square-wave pulse relevant parameter.As shown in figure 3, concrete control flow is：Power supply electrifying, enters
Communication check, if the order that downloads now is detected, entering program download mode, waiting PC control；If not
The order that downloads is detected, power supply enters state-detection.After state-detection is passed through, 1# power supply is numbered, other power supplys etc.
Treat.After the completion of numbering, respective power supply reads the electric current of corresponding numbering, time configuration, waits pulse generation order.Now, power supply is joined
Put and complete, send pulse command, power supply powers up to solenoid, and solenoid is in running order.The specific work process of power supply is：
After 1# power supply is connected to transmission pulse command, itself is exported, and 1# power supply is set up with 2# and 3# power supply by RS232 and communicated simultaneously
And sending the order making 2# and 3# power supply export, 2# and 3# power supply transmits after RS232 receives the output order of 1# transmission
Processed to single-chip microcomputer, single-chip microcomputer controls the drive system of Darlington transistor to be exported after processing, single after 1# output finishes
Piece machine controls closes Darlington transistor drive system, opens coil energy release system, and it is concurrent to be communicated by RS232 and 4# foundation
Send output order.By that analogy, control power supply sequence of power switching.
After power source communications detection finishes, control or remote software control by power supply is local, to power pulse signal.Often
Platform solenoid configures single power supply and powers, and is connected with power supply by electrical terminals 3, the single controller of every power configuration,
By controlling interface can automatically read must solenoid unit number Nt, the solenoid unit number Nc that simultaneously works is set, one
Working cell length Np.Wherein Nc and Np can be adjusted, as long as ensureing Nc+Np≤Nt, Nc≤Np, and solenoid receives power supply
The pulse signal sending, just can run.
If setting Nc is 3, Np is 5, the specific work process of power supply is：After 1# power supply is connected to transmission pulse command, from
Body is exported, and 1# power supply is set up with 2# and 3# power supply by RS232 and communicated and send the life making 2# and 3# power supply export simultaneously
Order, 2# and 3# power supply sends single-chip microcomputer to after RS232 receives the output order of 1# transmission and is processed, and single-chip microcomputer is processed
The drive system of Darlington transistor is controlled to be exported afterwards, Single-chip Controlling closes Darlington transistor drivetrain after 1# output finishes
System, opens coil energy release system, and is communicated by RS232 and 4# foundation and send output order.By that analogy, control electricity
Source sequence of power switching.
Described square wave drives magnetic force lifting device, as shown in figure 4, during its work, if spiral shell is arranged by controlling interface
Unit number Nc that spool works simultaneously is 3, i.e. three solenoid excitations simultaneously, and loads the square wave current conduct of distinct pulse widths
The initial raising section of target.Setting one working cell length Np of solenoid is 5, and that is, the dutycycle of solenoid work is 3/5.Specifically
Process is as follows：
1) according to setting, power supply powers up to solenoid；
2) 14, two grades of solenoids 15, three-level solenoids 16 of one-level solenoid are in simultaneously powered up state, and it is superimposed magnetic field
Attract the target in particle injecting mechanism 9；
3) gradient force to magnetic-particle 19 for the gradient magnetic, guiding particle moves to gap 17；
4) magnetic-particle 19 moves to gap 17, to one-level solenoid 14 power-off, powers up to level Four solenoid 18 simultaneously, this
When two grades of solenoids 15, three-level solenoid 16 and level Four solenoid 18 be in simultaneously powered up state lifting and be located at the position of gap 17
Magnetic-particle 19；
3) analogized according to the sequence of power switching of step 2, three, four, with the movement of solenoid sequence power on, its conveyance conduit 8
Magnetic field move also with sequence of power switching, magnetic-particle 19 lifted step by step；
4) the working distance unit number arranging is five, so, to 21, seven grades of solenoids 22 of six grades of solenoids and eight grades of spiral shells
While spool 23 is simultaneously powered up, power up again to one-level solenoid 14, two grades of solenoids 15, three-level solenoids 16, it is folded
Plus the target in magnetic field suction particle injected system 9, to lift next and to organize target.So 14, two grades of solenoids of one-level solenoid
15th, when three-level solenoid 16 powers up, the magnetic field very little in (gap 20) at upper one group of target, that is, to upper one group of magnetic-particle
Downward attraction very little, does not interfere with lifting each other.Realize the approximately continuous lifting of target by this way.
5) because square wave drives magnetic force lifting device to be accomplished that recycling of target, so being located at particle to draw section
Three solenoids are in operation, and load the larger impulse amplitude of interlude solenoid and shorter square wave pulsed current relatively, make
Three solenoids drawing section have larger electromagnetic force to the particle in conveyance conduit 9, and meanwhile, three solenoids drawing section are fast
Speed moves back electricity, makes the magnetic-particle 19 elevating can be transported to external pipe, by discharge orifice 10, accepts proton in target practice area 13
Bundle bombardment.
6) magnetic-particle through target practice area 13 continues back at particle injecting mechanism 9, realizes recycling of particle.
Be more than based on setting Nc be 5 for 3, Np the course of work, change Nc and Np, different experiments can be carried out, with
This preferably lifts parameter to find.By controlling interface realize power supply give solenoidal power-up time, solenoid power-off time,
The solenoid unit number of excitation and the electric current according to various location solenoid, loading different square-wave pulses simultaneously.Change this
A little parameters it can be seen that during different parameters the lifting flow of target different.In addition, the solenoid of Fig. 1 lifts dress as particle target
, it is desirable to particle is the particle containing magnetic material, the magnetic of magnetic-particle 19 is stronger for the critical piece put, same under conditions of, spiral shell
Spool is bigger to its electromagnetic force.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
