Move, the single-chip microcomputer outputs a set of pulse signals, the stepping motor takes one step, the value of the step number register is S=N-1, so the single-chip output M (M ≤ 1000) at the pulse signal, the stepping motor takes the M step, the number of steps The value of the register S=NM, when the pointer 4 reaches the limit A can no longer move, if the 1000 sets of pulse signals have not yet all output, then the stepper motor is in the stalled state until all the 1000 sets of pulse signals are output, stepping The motor stops rotating. At this time, the step number register is cleared to 0, and the single-chip microcomputer sets the position of the stepping motor at this time as the starting point of rotation;
然后,单片机再输出1000组反向脉冲信号给步进电机,步进电机反向转动,从而带动指针4从限位A处走向限位B处,单片机输出一组反向脉冲信号,步进电机就走一步,步数寄存器的数值S=0+1,所以单片机输出M组反向脉冲信号,步进电机就走了M步,步数寄存器的数值S=0+M,当到达限位B时,步数寄存器的数值S=1000,单片机将步进电机此时所在的位置设置为转动终点。Then, the MCU outputs 1000 sets of reverse pulse signals to the stepping motor, and the stepping motor rotates in the reverse direction, thereby driving the pointer 4 from the limit A to the limit B, and the single chip outputs a set of reverse pulse signals, the stepping motor Take one step, the value of the step register is S=0+1, so the MCU outputs M sets of reverse pulse signals, the stepper motor goes M step, the step register value S=0+M, when the limit B is reached When the value of the step register is S=1000, the MCU sets the position of the stepping motor at this time as the end point of rotation.
因此,单片机控制步进电机转动,当步数寄存器的数值S=0或S=1000时,单片机就知道步进电机已经运动到转动起点或终点,单片机不再输出与前一组方向相同的脉冲信号控制步进电机继续转动,单片机只输出与前一组方向相反的脉冲信号驱动步进电机反向转动或者不再继续输出信号,实现步进电机自动换向转动或停止转动的功能,从而不需要使用机械触碰开关就可以实现监控球机的自动换向转动;另外,单片机确定了步进电机的转动起点和终点后,步进电机在转动起点走向转动终点或从转动终点走向转动起点,步数寄存器的数值S由0递增1000或S从1000递减到0,所以步进电机的位移是与步数寄存器的数值S是一一对应的,单片机只需要记下步数寄存器的数值S就可以记录下步进电机的转动位移,因此可以根据实际需要编辑单片机程序在步数寄存器为某一个数值S时,单片机输出与前一组脉冲信号方向相反的脉冲信号或者停止输出脉冲信号,就可以控制步进电机在某一个记录转动位移上换向转动或停止转动。Therefore, the single-chip microcomputer controls the rotation of the stepping motor. When the value of the step register is S=0 or S=1000, the single-chip microcomputer knows that the stepping motor has moved to the starting point or the end point of the rotation, and the single-chip microcomputer no longer outputs the same pulse as the previous group. The signal control stepper motor continues to rotate, and the single chip only outputs the pulse signal opposite to the previous group to drive the stepping motor to rotate in the opposite direction or no longer continue to output the signal, thereby realizing the function of the stepping motor to automatically reverse or stop the rotation, thereby not It is necessary to use the mechanical touch switch to realize the automatic reversing rotation of the monitoring dome machine. In addition, after the single-chip microcomputer determines the starting point and the end point of the stepping motor, the stepping motor moves toward the end point of the rotation or the starting point of the rotation from the end point of the rotation. The value S of the step number register is incremented by 0 by 1000 or S is decremented from 1000 to 0. Therefore, the displacement of the stepping motor is one-to-one correspondence with the value S of the step number register. The microcontroller only needs to record the value S of the step number register. The rotational displacement of the stepper motor can be recorded, so the microcontroller program can be edited in the step number register according to actual needs. When the value of S, the microcontroller outputs a pulse signal with the previous set of pulse signal output is stopped, or a direction opposite to a pulse signal, the stepping motor can be controlled to rotate or stop rotating the transducer on a rotational displacement of a record.
上述步进电机Ⅰ21和步进电机Ⅱ22在控制程序通电初始化时,单片机分别向步进电机Ⅰ21和步进电机Ⅱ22输出正向脉冲信号的组数N可以根据它们各自转动起点与转动终点之间的角度大小和机械传动比计算得出,从而设定所需要的脉冲信号的组数N。When the stepping motor I21 and the stepping motor II22 are energized and initialized by the control program, the number of sets N of the forward pulse signals respectively outputted by the single-chip microcomputer to the stepping motor I21 and the stepping motor II22 may be based on the respective rotation starting point and the rotating end point. The angular magnitude and mechanical gear ratio are calculated to set the number N of sets of required pulse signals.
