[0035] Specifically, as Figure 2 shown, the calculation module includes: a selection unit 11, a multiplication unit 12, a rod group minimum value unit 13, and an overall minimum value unit 14; the selection unit 11 receives the lift / lower rod control signal input externally, the value 1 input externally, and the value -1 input externally, and generates a lift / lower rod control parameter; the multiplication unit 12 receives the lift / lower rod control parameter generated by the selection unit 11 and the position data of the current position of any regulating rod input externally, and generates the relative rod position data of the current any regulating rod; the rod group minimum value unit 13 receives the relative rod position data of the regulating rod in any rod group among the relative rod position data of any regulating rod generated by the multiplication unit 12, and generates the minimum relative rod position data in any rod group; the overall minimum value unit 14 receives the minimum relative rod position data in any rod group generated by the rod group minimum value unit 13, and generates the minimum relative rod position data among all regulating rods.

Exemplarily, the selection unit 11 can select a value from 1 and -1 according to UD and output it as X. In particular, when UD represents the rod insertion control signal, X outputs 1; when UD represents the rod withdrawal control signal, X outputs -1.

[0038] Among them, as Figure 5 shown, the first input terminal of the first multiplication unit 121 inputs the rod withdrawal / insertion control parameter X generated by the selection unit 11, the second input terminal of the first multiplication unit 121 inputs the position data I1 of the first regulating rod at the current position, and the output terminal of the first multiplication unit 121 is connected to the first input terminal of the first rod group minimum value unit 131, for outputting the relative rod position data IX1 of the first regulating rod. Exemplarily, the first multiplication unit 121 can multiply the value of X by the value of I1 to obtain IX1. In particular, when X is 1, IX1 = I1; when X is -1, IX1 = -I1.

[0039] Similarly, the second multiplication unit 122 inputs the rod withdrawal / insertion control parameter X and the position data I2 of the second regulating rod at the current position, and outputs the relative rod position data IX2 of the second regulating rod. Exemplarily, the connection mode and working logic of the second multiplication unit 122 are similar to those of the first multiplication unit 121, which will not be elaborated here.

Exemplarily, the connection mode and working logic of the third multiplication unit 123 are similar to those of the first multiplication unit 121, which will not be elaborated here.

[0041] Similarly, the fourth multiplication unit 124 inputs the rod withdrawal / insertion control parameter X and the position data I4 of the fourth regulating rod at the current position, and outputs the relative rod position data IX4 of the fourth regulating rod.

Specifically, the first rod group minimum value unit 131 can compare the numerical values of IX1 and IX4, and output the smaller numerical value as T1. Exemplarily, if I1 = 10, I4 = 8, when X = 1, IX1 = 10, IX4 = 8, since 8 < 10, the output T1 = 8 at this time, which is the rod position value with a lower actual rod position; when X = -1, IX1 = -10, IX4 = -8, since -10 < -8, the output T1 = -10 at this time, which is the rod position value with a higher actual rod position.

[0045] Similarly, the second rod group minimum value unit 132 inputs the relative rod position data IX2 of the second regulating rod and the relative rod position data IX5 of the fifth regulating rod, and outputs the minimum relative rod position data T2 in the second rod group.

Exemplarily, the overall minimum value unit 14 can compare the numerical values of T1, T2, and T3, and output the smaller numerical value as MI. Specifically, similar to the minimum value unit 131 of the first rod group, when X = 1, the rod position value with the lowest actual rod position is output at this time; when X = -1, the rod position value with the highest actual rod position is output at this time.

When either the first in-place determination unit 251 of the first rod group or the second in-place determination unit 261 of the first rod group issues an in-place determination signal, it sends a rod group clearing signal to the first rod group selection unit 271 to clear the first rod group selection signal SLT1.
