Specific embodiment
Principle of the invention, structure and specific embodiment are described further below in conjunction with the accompanying drawings.
Fig. 1 is the device overall structure diagram of multi-channel coil current switching of the present invention.Control module 1 has m
Road output interface 4, OUT1～OUTm, m is positive integer.Output interface 4 provides control signal, and the signal can be low and high level；Often
Road output interface 4 connects an electronic switch 2, and electronic switch 2 is closed or disconnection action in the presence of control signal.Electricity
One end of son switch 2 connects one or more driver 5, and the other end connects one or more coil 6；Electronic switch 2 is closed
The coil and driver conducting of then its connection is closed, coil is then powered；Electronic switch 2 disconnects then coil blackout.By measuring system
System draws mover present position, it is determined that needing number of coils and the position being powered, is passed to control instruction by communication interface 3
Control module 1, control module 1 determines the control signal of each road output interface 4 according to the instruction, and electronic switch 2 is according to the signal
Carry out action.Because moving-iron type motor needs to carry out big stroke motion, required number of coils is more, it is therefore desirable to which multichannel electronic is opened
Close 2, it is therefore desirable to multiple-channel output interface；To adapt to different application occasion, inside control module 3 programmable module is contained, according to
It is actually needed and it is programmed.During work, the instruction that control module is received according to communication interface 3, and utilize storage inside
Program, determine the control signal of multiple-channel output interface, and then control multi-channel electronic switch；Control module 3 also can direct basis
Internal processes determine the control signal of each road output interface 4；PC, industrial computer, field programmable gate array and PLC technology
Utensil has multiple-channel output interface, and the logic function that can be needed by programming realization, disclosure satisfy that the need to output interface
Ask；Control module 1 receives control instruction by communication interface 3, and by internal processes logical operation is carried out, and determines that each road output connects
The control signal of mouth 4.
Communication interface 3 can adopt in serial line interface, parallel interface, USB interface, optical fiber interface and Ethernet interface
Plant or multiple combination.Wherein serial line interface can be used for the situation relatively low to rate request；And parallel interface can provide compared with
Fast transmission speed；USB interface can improve higher transmission speed；Optical Fiber Transmission mode can then provide farther distance, more steady
Fixed signal transmission, it is adaptable to more accurate occasion；Ethernet interface also can provide high-speed remote from data transfer.
Fig. 2 and Fig. 3 give two kinds of working methods of the device of multi-channel coil current switching of the present invention.Due to every
Road electronic switch 2 is closed by a control signal control realization or disconnected, separate between each electronic switch, thus this is cut
Changing device has higher flexibility.As shown in Fig. 2 continuum coil power supply is realized by controlling adjacent electronic switch 2,
All coils are continuously powered in feasible region；When non-conterminous coil electricity is needed, closure respective electronic switch 2, therefore phase
Answer the coil must be to power, it is not necessary to coil blackout, form the coil electricity of discrete regions as shown in Figure 3.
Fig. 4 represents a kind of building form of electronic switch.The control signal of the output of output interface 4 accesses latch cicuit, enters
Row storage, when control signal that and if only if changes, the signal in latch cicuit just can change, and export to isolation circuit, enter
Row isolation conversion, such as Phototube Coupling conversion improves electronic switch stability；Then the signal after converting passes through push-pull circuit control
FET circuit processed, by controlling being turned on or off for FET, and then realizes the effect for switching, as shown in Figure 4.Recommend
Circuit improves the load capacity of circuit, and switching speed can be improved again.When system resource is enough or when requiring relatively low, can not adopt
With latch cicuit, control signal is directly inputted to isolation circuit.
Fig. 5 represents the connected mode of electronic switch, and the first driver accesses j roads electronic switch 2, and j is positive integer, the electricity per road
Son switch 2 connect a coils, electronic switch 2 receive control module 1 control signal carry out action, it would be desirable to coil with drive
Dynamic device 5 is connected；According to actual needs one or more coil and driver are connected with actuator power；In principle every time most
There is a coil to access same driver more；If driver functions allow that multiple coils can be said while accessing same with power
In individual driver, multi-coil energization is carried out.
Fig. 6 represents a kind of working method of control module.Control module 1 receives control instruction by communication interface 3, control
Instruction processed is transferred to processor, and processor calls the program being stored in ROM to carry out computing, and computing intermediate variable or result are stored
In RAM, processor determines the control signal of each output interface according to operation result, and then controls and each output interface phase
Electronic switch even.Communication interface 3 can also send specified signal.
Fig. 7 represents a kind of workflow of control module.Control module 1 receives external control instruction using communication interface 3,
Internal processes are called, the state of all electronic switches is determined, then all control signals is determined according to the state of electronic switch, and
Above-mentioned control signal is sent using multiple-channel output interface 4, electronic switch realize in the presence of control signal disconnect or
Closed action, and then coil is accessed into driver, or disconnect from driver.
