Background
In the field of electrical automation control, it is a common method to control equipment by using incremental encoder pulse signals. As shown in fig. 1, the PLC collects a pulse square wave input signal through the high-speed counter module, accumulates the pulse square wave input signal in the input process mapping area, and stores the pulse square wave input signal as a real-time count value that changes within a fixed range, and when the pulse square wave input signal exceeds the storage range, the count value overflows. According to the mode of the counting value, a plurality of counting modes can be divided, wherein the most common counting mode is continuous cycle counting, as shown in fig. 2 and fig. 3.
In fig. 2 and 3, PI _ MAX is the upper limit value of the real-time count value, and PI _ MIN is the lower limit value of the real-time count value. In fig. 2, in a fixed range, the encoder rotates (moves) in one direction, and the real-time count value of the pulse signal is counted from small to large in a positive direction; when the counting value counts in the positive direction and reaches the upper limit PI _ MAX and the next positive pulse arrives, the counting value jumps to the lower limit PI _ MIN, and the positive counting is recovered from the lower limit, and the continuous positive counting can not exceed the upper limit. In fig. 3, the encoder rotates (moves) in the other direction within a fixed value range, and the real-time count value of the pulse signal is counted from large to small in a reverse direction; when the counting value is reversely counted and reaches the lower limit PI _ MIN, the counting value jumps to the upper limit PI _ MAX when the next negative pulse comes, and the reverse counting is recovered from the upper limit, and the continuous reverse counting cannot be performed again when the counting value is lower than the lower limit. If the required counting range exceeds the upper limit value or the lower limit value in practical application, the counting measurement cannot be completed.

Referring to fig. 4, a PLC pulse signal counting method of the present invention is shown, which includes the following steps:
step 1, a PLC system samples pulse signals of a pulse encoder to obtain a real-time pulse count value PI _ DINT which changes in a continuous period;
step 2, setting a variable PI _ STR-PI _ MIN;

setting a variable DN _ F to (PI _ MAX-PI _ MIN)/2;
step 4, setting a variable PI _ OLD ═ PI _ NEW;
step 5, setting a variable PI _ DEV as PI _ DINT-PI _ OLD;
step 6, comparing the sizes of the PI _ DEV and the UP _ F, DN _ F, and if the UP _ F is not less than the PI _ DEV and not more than the DN _ F, jumping to step 7; if PI _ DEV is less than or equal to UP _ F, skipping to step 8; if the PI _ DEV is more than or equal to DN _ F, jumping to the step 9;
and 7, when the PI _ DINT counting value is not increased to the upper limit value PI _ MAX or the PI _ DINT counting value is not decreased to the lower limit value PI _ MIN, obtaining the relation PI _ DELTA _ PI _ DEV.
Step 8, when the up count of the PI _ DINT count value reaches the upper limit value PI _ MAX or the critical upper limit value PI _ MAX, when the next cycle pulse arrives, the PI _ DINT jumps to the lower limit value PI _ MIN or the jump value is larger than the lower limit value PI _ MIN, and then PI _ DELTA is PI _ DEV + (PI _ STR + 1);
step 9, when the PI _ DINT count value counts down to reach the lower limit value PI _ MIN or the critical lower limit value PI _ MIN, when the next cycle pulse arrives, the PI _ DINT jumps to the upper limit value PI _ MAX or the jump value is smaller than the upper limit value PI _ MAX, and then PI _ DELTA is PI _ DEV- (PI _ STR + 1);
step 10, outputting the value of PI _ DELTA according to the relational expression;
step 11, set PI _ DINT to PI _ NEW, and go to the step to set PI _ OLD to PI _ NEW to perform loop calculation.
Wherein, PI _ DELTA is the final output value and is the real-time variation value of PI _ DINT; PI _ MAX is the upper limit value of PI _ DINT in the period; PI _ MIN is the lower limit value of PI _ DINT in the period; PI _ NEW is the register value of PI _ DINT at the end of the last cycle, and is used as the input value of PI _ OLD. PI _ OLD is a register value of PI _ DINT at the end of the last period; PI _ STR is PI _ MAX-PI _ MIN.
In embodiment 1, the PLC system samples the pulse signal of the pulse encoder to obtain a real-time pulse count value PI _ DINT that changes in a continuous period. PI _ DINT is a signed 16-bit integer, so PI _ MIN is-32768 and PI _ MAX is 32767.
1. PI _ STR-PI _ MAX-PI _ MIN 32767- (-32168) 65535
2. Setting UP _ F ═ (PI _ MIN-PI _ MAX) ÷ 2 ═ 32768-32767) ÷ 2 ═ 32767.5
Set DN _ F ═ (PI _ MAX-PI _ MIN) ÷ 2 ═ 32767- (-32768)) ═ 32767.5
3. The PI _ OLD is set to PI _ NEW, which is the value of PI _ DINT at the end of a scanning cycle on the PLC system.
4. And setting PI _ DEV as PI _ DINT-PI _ OLD, wherein according to the calculation method, when the PLC system is operated, the encoder rotates, and PI _ DINT does not exceed the upper limit value PI _ MAX and does not fall below the lower limit value PI _ MIN, PI _ DEV is an increment value in a scanning period of the PLC system, for example, the encoder rotates uniformly in the positive direction, the pulse increment value in a unit scanning period is 3, and PI _ DEV is 3.
5. PI _ DEV is compared in size with UP _ F and DN _ F. According to the difference of the comparison values, selective calculation is carried out, and the conditions for selecting jump calculation are as the following steps 6, 7 and 8.
6. When UP _ F ≦ PI _ DEV ≦ DN _ F, i.e., -32767.5 ≦ PI _ DEV ≦ 32767.5, proceed to step 9.
7. When PI _ DEV ≦ UP _ F, i.e., PI _ DEV ≦ -32767.5, it jumps to step 10. This is the case when PI _ DINT reaches the upper limit PI _ MAX (i.e. PI _ DINT reaches 32767), and when the PLC system arrives at the next scanning period and the pulse is further increased by one or more numbers in the forward direction, for example, PI _ DINT is-32766, PI _ DEV is-32766-32767 is-65533 < -32767.5.
8. When PI _ DEV ≧ DN _ F and PI _ DEV ≧ 32767.5, go to step 11. This is the case when PI _ DINT reaches the lower limit PI _ MIN (i.e., PI _ DINT — 32768), and when the PLC system arrives at the next scanning period and the pulse is increased by one or more numbers in the reverse direction, for example, PI _ DINT 32766, then PI _ DEV 32766- (-32768) ═ 65534> 32767.5.
9. If the condition 6 is satisfied, jumping to the step: when the PI _ DINT count value is not increased to the upper limit value PI _ MAX (32767), and PI _ DINT is not decreased to the lower limit value (-32768), the final output value PI _ DELTA is PI _ DEV is 3.
10. When condition 7 is satisfied, the process jumps to this step, and the final output value PI _ DELTA ═ PI _ DEV + (PI _ STR +1), for example: when PI _ DINT jumps from 32767 to-32766, then:
the final output value PI _ DELTA ═ PI _ DEV + (PI _ STR +1) — (32766-.
11. When condition 8 is satisfied, the process jumps to this step, and the final output value PI _ DELTA is PI _ DEV- (PI _ STR +1), for example:
when PI _ DINT jumps from-32768 to 32756, then:
the final output value PI _ DELTA ═ PI _ DEV- (PI _ STR +1) ═ 32765- (-32768)) - (PI _ STR +1) ═ 3, which coincides with the result of the inverse reduction of the actual result by 3 pulses. Since the rotation is in the reverse direction, "-" is used for representation.
12. PI _ DINT is set to PI _ NEW.
In the above embodiment, PI _ DELTA is the final output, and when the encoder rotates at a constant speed, PI _ DELTA is a constant value and is not limited by the upper limit of PI _ MAX and the lower limit of PI _ MIN. If other calculation methods are used, functions of distance range measurement expansion, signal tracking, position detection and the like can be conveniently realized.

in the embodiment of the present invention, PI _ DEV is compared with UP _ F, DN _ F, and if UP _ F is not greater than PI _ DEV is not greater than DN _ F, when the PI _ DINT count value is not increased to the upper limit PI _ MAX or PI _ DINT is not decreased to the lower limit PI _ MIN, the relationship PI _ DELTA is PI _ DEV. (ii) a If PI _ DEV is less than or equal to UP _ F, when the PI _ DINT count value reaches the upper limit value PI _ MAX or the critical upper limit value PI _ MAX, when the next cycle pulse arrives, PI _ DINT jumps to the lower limit value PI _ MIN or the jump value is greater than the lower limit value PI _ MIN, then PI _ DELTA is PI _ DEV + (PI _ STR + 1); if PI _ DEV is not less than DN _ F, when the PI _ DINT counting value reaches the lower limit value PI _ MI or the critical lower limit value PI _ MIN, PI _ DINT jumps to the upper limit value PI _ MAX or the jump value is less than the upper limit value PI _ MAX when the next cycle pulse arrives, and PI _ DELTA is PI _ DEV- (PI _ STR + 1).
