Accompanying drawing explanation
Fig. 1 is existing primary circuit structure;
Fig. 2 is the circuit structure by method design of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1, for the electromagnet control method of prior art, in the structure shown here, can see that each control module respectively controls an electromagnet, in each control module, comprise a metal-oxide-semiconductor, with a diode for afterflow, in Fig. 1, one has 12 electromagnet, therefore need 12 control modules to go to control respectively, but the reaction time of electromagnet is 15ms, in practical situations both, often to only require that within the regulation execution time reaction just can such as 100ms, therefore have larger redundancy in time.
As shown in Figure 2, for the control circuit for electromagnet by method design of the present invention, suppose that the regulation execution time required is 100ms, the time of work of electromagnet reaction is 15ms, as long as namely in 100ms, electromagnet is finished the work, the pulse voltage of electromagnet is 24V, then this control module is in idle condition in remaining 85ms, utilize this control module of this idle condition can also control other work of electromagnet, namely this control module can also control at most 5 electromagnet in proportion, in this theoretical foundation, design a kind of novel electromagnet control method.
Calculate the number of the required electromagnet controlled, such as be set to Z, by control module, (each control module is respectively set to upper and lower side two groups containing a metal-oxide-semiconductor, the number that upper end is arranged is set to X, the number that lower end is arranged is Y, due to when X and Y long-pending be less than electromagnet sum time, will occur that certain electromagnet is uncontrolled, the X number therefore wherein arranged and Y number product must be more than or equal to the number of the electromagnet of required control.On this basis, the number of control module will reduce as far as possible thus reach maximum utilization factor,
Embodiment one:
Such as shown in Fig. 2, the number of electromagnet is 12, suppose that the regulation execution time required is 100ms, work of electromagnet reaction time be 15ms, as long as namely in 100ms electromagnet finish the work, the pulse voltage of electromagnet is 24V, each control module can control at most 6 electromagnet in proportion, therefore upper and lower side settings can have following combination and 1*12,2*6,3*4,4*3 etc. combination, and certain product value can also be greater than 12, and 1*13,2*7 etc. combination; Choose one group that control module number is minimum in these combinations, if such as choose 1*12, then need 13 control modules; Choose 2*6, then need 8 control modules, choose 3*4, then need 7 control modules, the like learn, when choosing 3*4 or 4*3, required control module is minimum, only need 7 just passable.In Fig. 2 selection is 3*4 combination, and it is at most 4 electromagnet that each control module controls,
Namely control module Q1 and Q4 combines control first electromagnet; Control module Q1 and Q5 combines control second electromagnet, and control module Q1 and Q6 combines control the 3rd electromagnet, and control module Q1 and Q7 combines control the 4th electromagnet;
Control module Q2 and Q4 combines control the 5th electromagnet; Control module Q2 and Q5 combines control the 6th electromagnet, and control module Q2 and Q6 combines control the 7th electromagnet, and control module Q2 and Q7 combines control the 8th electromagnet;
Control module Q3 and Q4 combines control the 9th electromagnet; Control module Q3 and Q5 combines control the tenth electromagnet, and control module Q3 and Q6 combines control the 11 electromagnet, and control module Q3 and Q7 combines control the 12 electromagnet;
Arranging a diode in addition at each electromagnet place is to prevent current return, if such as do not arrange diode F12, when control module Q1 and Q4 conducting, electric current not only passes through from first electromagnet, also can flow through from the 9th electromagnet, the tenth electromagnet thus and second electromagnet cause loop, (flow into second electromagnet from metal-oxide-semiconductor Q1, second electromagnet flows into the tenth electromagnet, tenth electromagnet flows into the 9th electromagnet, and the 9th electromagnet flows into metal-oxide-semiconductor Q4 together with first electromagnet) by that analogy.
Have employed altogether 7 metal-oxide-semiconductors and 19 diodes, 12 metal-oxide-semiconductors needed in original control in this design.
The electromagnet that control module connects generally does not exceed its limit controlled, and the most multipotency of upper end control module controls 6 electromagnet in this example, and when design, is controlled 4 electromagnet, therefore meet designing requirement.
Identical with the time that work of electromagnet is reacted or when being less than when the regulation execution time that hypothesis requires, the time of work of electromagnet reaction then can be shortened by improving voltage, the regulation execution time such as required is 15ms, the time of work of electromagnet reaction is also 15ms, if do not carrying on high-tension basis, this method cannot be used to carry out multiplexing control, therefore electromagnet voltage can be improved, such as bring up to 48V, then the working reaction time of electromagnet can shorten to 7.5ms, and namely a control module can control 2 electromagnet at most.
Embodiment two
When electromagnet quantity is 81, suppose that the regulation execution time required is 150ms, the time of work of electromagnet reaction is 15ms, as long as namely in 150ms, electromagnet is finished the work, the pulse voltage of electromagnet is 24V, each control module can control at most 10 electromagnet in proportion, can adopt the combination of 9*9, because this combination has employing 18 control modules altogether.Each control module controls 9 electromagnet, meets the requirements.
Its connected mode can connect with reference to the mode of figure 2, and namely upper end arranges 9 control modules, and each control module is identical with the control module in Fig. 2, and lower end arranges 9 control modules, and each control module is identical with the control module in Fig. 2; The each control module in upper end connects 9 electromagnet, wherein 1st ~ 9 control modules of upper end and the 10th control module combination of two control the 1st, 10,19,28,37,46,55,64,73 electromagnet; 1st ~ 9 control modules of upper end and the 11st control module combination of two control the 2nd, 11,20,29,38,47,56,65,74 electromagnet; The like.
Have employing 18 metal-oxide-semiconductors and 99 diodes altogether in this design, in existing design, need employing 81 metal-oxide-semiconductors.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be considered as in scope.
