Description
Technical field
The utility model relates to step motor control equipment, particularly a kind of Single-chip Controlling stepping motor speed regulating device.
Background technology
Stepping motor is digital control motor, it becomes angular displacement with shift pulse signal, namely give a pulse signal, stepping motor just rotates an angle, and stepping motor can be divided into reaction stepping motor (being called for short VR), p-m step motor (being called for short PM) and composite stepper motor.Stepping motor is different from other maximum characteristics of controlling motors, and it is controlled by the input pulse signal, and namely total rotational angle of motor is determined by the input pulse number, and the rotating speed of motor is determined by pulse signal frequency.The drive circuit of stepping motor is according to control signal work, and its basic principle effect is as follows:
(1) control commutation order
This process of energising commutation is called pulse distribution.For example: the triple time working method of three-phase stepper motor, its each phase power-up sequence is A-B-C-D, the energising control impuls must be controlled respectively A, B, C, the break-make of D phase in strict accordance with this order.
(2) the control step motor turns to
If given working method positive sequence commutation energising, the stepping motor forward, if by inverted sequence energising commutation, then just counter-rotating of motor.
(3) speed of control step motor
If send out a control impuls to stepping motor, it just turns a step, sends out a pulse again, and it can turn a step again.The interval of two pulses is shorter, and stepping motor just turns sooner.Adjust the pulse frequency that single-chip microcomputer sends, just can carry out speed governing to stepping motor, therefore be very suitable for Single-chip Controlling, raising result of use, but the device of so far there are no useful Single-chip Controlling stepping motor speed governing.
Summary of the invention
For above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of Single-chip Controlling stepping motor speed regulating device, can effectively solve stepping motor by the Single-chip Controlling signal, carries out speed governing, guarantees the problem of service efficiency.
The technical scheme that the utility model solves is, comprise housing, single-chip microcomputer, power supply, computer and display, single-chip microcomputer and the programmed logic module that links to each other, electric power generating composition single-chip microcomputer main control unit, place in the housing, single-chip microcomputer links to each other with computer, and display is housed on the computer, and single-chip microcomputer connects encoder through stepping motor, encoder links to each other with logic module, and the socket that connects input pulse and segmentation instruction is arranged on the input of logic module.
The utility model is simple in structure, and is novel unique, easily installs and uses, effective, greatly improved result of use and the operating efficiency of stepping motor.
Description of drawings
Fig. 1 is structure connection box diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
By shown in Figure 1, the utility model comprises housing, single-chip microcomputer, power supply, computer and display, single-chip microcomputer and the programmed logic module that links to each other, electric power generating composition single-chip microcomputer main control unit, place in the housing, single-chip microcomputer links to each other with computer, and display is housed on the computer, and single-chip microcomputer connects encoder through stepping motor, encoder links to each other with logic module, and the socket that connects input pulse and segmentation instruction is arranged on the input of logic module.
In order to guarantee result of use, described display adopts 1602 LCD MODULE, display measurement parameter and all measurement results of demonstration; Described single-chip microcomputer adopts the STC89C52 analog line driver, mainly comprises three parts, and control signal buffer circuit, main circuit and automatic half current circuit can utilize simple programming to realize (prior art has the commercially available prod).
Operation principle of the present utility model is:
(1) control commutation order
This process of energising commutation is called pulse distribution.For example: the triple time working method of three-phase stepper motor, its each phase power-up sequence is A-B-C-D, the energising control impuls must be controlled respectively A, B, C, the break-make of D phase in strict accordance with this order.
(2) the control step motor turns to
If given working method positive sequence commutation energising, the stepping motor forward, if by inverted sequence energising commutation, then just counter-rotating of motor.
(3) speed of control step motor
If send out a control impuls to stepping motor, it just turns a step, sends out a pulse again, and it can turn a step again.The interval of two pulses is shorter, and stepping motor just turns sooner.Adjust the pulse frequency that single-chip microcomputer sends, just can carry out speed governing to stepping motor.
Specific works situation of the present utility model is, main control chip adopts the STC89C52 single-chip microcomputer, show and adopt 1602 liquid crystal, because stepper motor speed is set by the potentiometer input, uses outside AD tlc5510, the AD clock source connects 89C52 ALE pin, AD is for parallel, AD uses single-chip microcomputer P1 mouth, can directly read, according to the corresponding data setting speed.Closed-loop control is adopted in stepper motor speed control, because the fluctuation of traditional pid control algorithm is larger, we adopt classification to set the way of acceleration, and the speed that encoder feedback is returned and setting speed compare and determine to accelerate or slow down, software simulation acceleration-deceleration process, Design of Stepper Motor Subdivision provides by driving chip TB6560, owing to driving the segmentation instruction by the interface level decision of programmed logic module, single-chip microcomputer passed through counter 0 initialize in the suitable moment, the frequency change that sets the acceleration and deceleration process (is speed, acceleration change), to prevent step-out.For example, in point position control, set speed curve diagram, when starting and raising speed, make stepping motor produce enough torque actuated loads, speed and the acceleration of catching up with regulation; When slowing down, falling characteristic makes load not produce overshoot, stops at the position of regulation.Program curing in the startup sub-driver circuit moves through power amplification rear drive stepping motor to produce the pulse of certain frequency.The change of the stepping motor direction of motion and startup and stop to realize by the computer control hardware control circuit.
