Description

Technical Field

[0001] This invention relates to the field of nuclear reactor engineering technology, and in particular to an automatic rod selection system and method for realizing the principle of symmetrical and aligned moving rods. Background Technology

[0002] Control rods, made of neutron-absorbing materials, function to control the chain reaction rate within the reactor at a predetermined level, enabling the start-up, shutdown, and power regulation of the nuclear reactor. The nuclear reactor power control system, operated manually or automatically, changes or maintains the reactor power by altering the position of the control rods, playing a crucial role in ensuring the safe and stable operation of the nuclear reactor.

[0003] Each high-temperature gas-cooled reactor (HTGR) has 24 control rods, categorized as safety rods, regulating rods, and compensating rods. The regulating rods consist of six rods, divided into three groups: rods 1 and 4 form one group, rods 2 and 5 form another, and rods 3 and 6 form a third. The two rods in each group are positioned symmetrically across the reactor. When the reactor power control system is in automatic adjustment mode, the reactor power is altered or maintained by alternately raising or lowering the six regulating rods. In automatic adjustment mode, the six regulating rods must adhere to the principle of "symmetrical alignment" to prevent distortion of the neutron density distribution within the reactor, which could lead to excessively high local neutron density, hot spots, and, in severe cases, fuel rod burnout.

[0004] The principle of symmetrical and aligned moving rods has the following specific requirements:

[0005] (1) When lifting the rod, select the lowest one; when lowering the rod, select the highest one.

[0006] (2) When the selected bar, when the lifting or lowering of the bar reaches the specified limit, stop the operation on the bar and switch to another bar in the same group that is symmetrical to it.

[0007] (3) After both rods in this group have been moved once, the selection and movement of the rods are carried out again according to the principles (1) and (2) above.

[0008] (4) After the new bar raising / lowering operation command arrives, select the bar again.

[0009] Existing automatic rod selection methods cannot simultaneously meet the above four requirements of the symmetrical and aligned moving rod principle. There is an urgent need for an automatic rod selection method that can realize the symmetrical and aligned moving rod principle. Summary of the Invention

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0090] This invention proposes a more complete automatic rod selection system and method. In automatic adjustment mode, the raising / lowering operation of the six adjustment rods can follow the principle of symmetrical and aligned moving rods, so as to make the core power distribution uniform and ensure the safe operation of the nuclear power unit.

[0091] like Figure 1 As shown, an automatic rod selection system for implementing the principle of symmetrical and aligned moving rods, provided by an embodiment of the present invention, includes: a calculation module 1, a reset module 2, a group selection module 3, and a rod selection module 4. Wherein:

[0092] The calculation module 1 is used to generate the relative position data of the target regulating rod, the minimum relative position data in the target rod group, and the minimum relative position data among all regulating rods based on the received lifting / lowering rod control signal and the current position data of the target regulating rod.

[0093] In this embodiment of the invention, the target adjusting rod is any one of the six adjusting rods. The six target adjusting rods are divided into three groups: target adjusting rod 1 and target adjusting rod 4 form one group, target adjusting rod 2 and target adjusting rod 5 form another group, and target adjusting rod 3 and target adjusting rod 6 form yet another group. These three groups constitute the three target rod groups.

[0094] The reset module 2 is used to generate a reset signal based on the received lifting / lowering bar control signal or manual / automatic control mode signal. The reset signal is used to reset the selection signal of all bar groups and the selection signal of all adjusting bars.

[0095] The selection module 3 is used to generate a target rod group selection signal and a target rod group dual rod positioning confirmation signal based on the smallest relative rod position data in the target rod group and the smallest relative rod position data in all the regulating rods generated by the calculation module, as well as the externally input power control system automatic control mode signal and target regulating rod positioning signal.

[0097] In one embodiment of the present invention, such as Figure 2 As shown, the calculation module 1 includes: a selection unit 11, a multiplication unit 12, a bar group minimum value unit 13, and an overall minimum value unit 14. Wherein:

[0098] The selection unit 11 is used to receive the lifting / lowering bar control signal and the target value, and generate lifting / lowering bar control parameters according to the lifting / lowering bar control signal and the target value.

[0099] In this embodiment of the invention, the target values ​​can be 1 and -1, representing bar lifting control and bar lowering control, respectively. In practical applications, the selection unit 11 receives the externally input bar lifting / lowering control signal, the externally input value 1, and the externally input value -1, and generates bar lifting / lowering control parameters.

[0100] The multiplication unit 12 is used to generate the relative position data of the target regulating rod based on the lifting / lowering rod control parameters generated by the selection unit 11 and the externally input target regulating rod current position data.

[0101] In this embodiment of the invention, the target adjusting rod is any one of the six adjusting rods.

[0102] The minimum value unit 13 of the rod group is used to generate the minimum relative rod position data in the target rod group based on the relative rod position data of the target adjustment rod generated by the multiplication unit 12.

[0103] In this embodiment of the invention, there are six target adjustment rods, divided into three groups. Target adjustment rods 1 and 4 form one group, target adjustment rods 2 and 5 form another group, and target adjustment rods 3 and 6 form yet another group. These three groups constitute three target rod groups. The group consisting of target adjustment rods 1 and 4 is the first target rod group, the group consisting of target adjustment rods 2 and 3 is the second target rod group, and the group consisting of target adjustment rods 3 and 6 is the third target rod group. In this embodiment, the rod group minimum value unit 13 generates the minimum relative rod position data in the target rod group based on the relative rod position data of the target adjustment rods generated by the multiplication unit 12.

[0104] The overall minimum value unit 14 is used to generate the minimum relative rod position data among all regulating rods based on the minimum relative rod position data among all target rod groups.

[0106] In this embodiment of the invention, combined with Figure 5As shown, the selection unit 11 includes three input terminals: a first input terminal, a second input terminal, and a third input terminal.

[0107] In this embodiment of the invention, the selection unit 11 can select a value from 1 and -1 and output it as X based on the lifting / lowering bar control signal UD. Specifically, when the lifting / lowering bar control signal UD represents a lifting control signal, the output of X is 1; when the lifting / lowering bar control signal UD represents a lowering control signal, the output of X is -1.

The output terminal of the first multiplication unit 121 is connected to the first input terminal of the first bar group minimum value unit 131, and is used to output the relative bar position data IX1 of the first adjusting bar. For example, the first multiplication unit 121 can multiply the value of X by the value of I1 to obtain IX1. Wherein, when X is 1, IX1 = I1; when X is -1, IX1 = -I1.

The output terminal of the second multiplication unit 122 is connected to the first input terminal of the second bar group minimum value unit 132, and is used to output the relative bar position data IX2 of the second adjusting bar. For example, the second multiplication unit 122 can multiply the value of X by the value of I2 to obtain IX2. Wherein, when X is 1, IX2 = I2; when X is -1, IX2 = -I2.

[0110] like Figure 5As shown, the first input terminal of the third multiplication unit 123 receives the lifting / lowering bar control parameter X generated by the selection unit 11, and the second input terminal receives the current position data I3 of the third adjusting bar (i.e., adjusting bar 3). The output terminal of the third multiplication unit 123 is connected to the first input terminal of the third bar group minimum value unit 133, and is used to output the relative bar position data IX3 of the third adjusting bar. For example, the third multiplication unit 123 can multiply the value of X by the value of I3 to obtain IX3. Wherein, when X is 1, IX3 = I3; when X is -1, IX3 = -I3.

[0111] like Figure 5 As shown, the first input terminal of the fourth multiplication unit 124 receives the lifting / lowering bar control parameter X generated by the selection unit 11, and the second input terminal receives the current position data I4 of the fourth adjusting bar (i.e., adjusting bar 4). The output terminal of the fourth multiplication unit 124 is connected to the second input terminal of the first bar group minimum value unit 131, and is used to output the relative bar position data IX4 of the fourth adjusting bar. For example, the fourth multiplication unit 124 can multiply the value of X by the value of I4 to obtain IX4. Wherein, when X is 1, IX4 = I4; when X is -1, IX4 = -I4.

[0112] like Figure 5 As shown, the first input terminal of the fifth multiplication unit 125 receives the lifting / lowering bar control parameter X generated by the selection unit 11, and the second input terminal receives the current position data I5 of the fifth adjusting bar (i.e., adjusting bar 5). The output terminal of the fifth multiplication unit 125 is connected to the second input terminal of the second bar group minimum value unit 132, and is used to output the relative bar position data IX5 of the fifth adjusting bar. For example, the fifth multiplication unit 125 can multiply the value of X by the value of I5 to obtain IX5. Wherein, when X is 1, IX5 = I5; when X is -1, IX5 = -I5.

[0113] like Figure 5 As shown, the first input terminal of the sixth multiplication unit 126 receives the lifting / lowering bar control parameter X generated by the selection unit 11, and the second input terminal receives the current position data I6 of the sixth adjusting bar (i.e., adjusting bar 6). The output terminal of the sixth multiplication unit 126 is connected to the second input terminal of the third bar group minimum value unit 133, and is used to output the relative bar position data IX6 of the sixth adjusting bar. For example, the sixth multiplication unit 126 can multiply the value of X by the value of I6 to obtain IX6. Wherein, when X is 1, IX6 = I6; when X is -1, IX6 = -I6.

[0114] like Figure 6As shown, the first input terminal of the minimum value unit 131 of the first rod group receives the relative rod position data IX1 of the first adjusting rod, and the second input terminal receives the relative rod position data IX4 of the fourth adjusting rod. The output terminal is connected to the first input terminal of the overall minimum value unit 14, and is used to output the smallest relative rod position data T1 in the first rod group. Specifically, the minimum value unit 131 of the first rod group can compare the values ​​of IX1 and IX4 and output the smaller value as T1. For example, assuming I1 = 10 and I4 = 8, when X = 1, IX1 = 10 and IX4 = 8. Since 10 > 8, the output T1 = 8, that is, the lower actual rod position value is output; when X = -1, IX1 = -10 and IX4 = -8. Since -10 < -8, the output T1 = -10, that is, the higher actual rod position value is output.

[0115] like Figure 6 As shown, the first input terminal of the second rod group minimum value unit 132 receives the relative rod position data IX2 of the second adjusting rod, and the second input terminal receives the relative rod position data IX5 of the fifth adjusting rod. The output terminal is connected to the second input terminal of the overall minimum value unit 14, and is used to output the smallest relative rod position data T2 in the second rod group. Specifically, the second rod group minimum value unit 132 can compare the values ​​of IX2 and IX5 and output the smaller value as T2. For example, assuming I2 = 10 and I5 = 8, when X = 1, IX2 = 10 and IX5 = 8. Since 10 > 8, the output T2 = 8, that is, the lower actual rod position value is output; when X = -1, IX2 = -10 and IX5 = -8. Since -10 < -8, the output T2 = -10, that is, the higher actual rod position value is output.

[0116] like Figure 6 As shown, the first input terminal of the minimum value unit 133 of the third rod group receives the relative rod position data IX3 of the third adjusting rod, the second input terminal receives the relative rod position data IX6 of the sixth adjusting rod, and the output terminal is connected to the third input terminal of the overall minimum value unit 14, used to output the smallest relative rod position data T3 in the third rod group. Specifically, the minimum value unit 133 of the third rod group can compare the values ​​of IX3 and IX6 and output the smaller value as T3. For example, assuming I3 = 10 and I6 = 8, when X = 1, IX3 = 10 and IX6 = 8. Since 10 > 8, the output T3 = 8, that is, the lower actual rod position value is output; when X = -1, IX3 = -10 and IX6 = -8. Since -10 < -8, the output T3 = -10, that is, the higher actual rod position value is output.

[0117] Further integration Figure 6As shown, the first input terminal of the overall minimum value unit 14 receives the smallest relative rod position data T1 in the first rod group, the second input terminal receives the smallest relative rod position data T2 in the second rod group, and the third input terminal receives the smallest relative rod position data T3 in the third rod group. The output terminal outputs the smallest relative rod position data M among all adjusting rods. For example, the overall minimum value unit 14 can compare the values ​​of T1, T2, and T3 and output the smaller value as MI. Continuing with the previous example, when X = 1, the output is the lowest actual rod position value; when X = -1, the output is the highest actual rod position value.

[0118] In one embodiment of the present invention, such as Figure 7 As shown, the reset module 2 includes: a lifting rod reset unit 21, a lowering rod reset unit 22, a manual judgment unit 23, and a reset generation unit 24. Wherein:

[0119] The input terminal of the lifting rod reset unit 21 is used to receive the lifting / lowering rod control signal, and the output terminal is connected to the first input terminal of the reset generation unit 24. The lifting rod reset unit 21 is used to output the lifting rod reset signal.

[0120] The input terminal of the lowering bar reset unit 22 is used to receive the raising / lowering bar control signal, and the output terminal is connected to the second input terminal of the reset generation unit 24. The lowering bar reset unit 22 is used to output the lowering bar reset signal.

[0121] The first input terminal of the manual judgment unit 23 is used to receive the manual / automatic control mode signal, the second input terminal is used to receive the value 0, and the output terminal is connected to the third input terminal of the reset generation unit 24. The manual judgment unit 23 is used to output a manual reset signal.

[0122] The first input terminal of the reset generation unit 24 is used to receive the lifting reset signal, the second input terminal is used to receive the lowering reset signal, the third input terminal is used to receive the manual reset signal, and the output terminal is used to output the reset signal RESET. The reset signal RESET is used to reset the selection signals of all rod groups and all adjustment rods.

[0123] As an optional implementation of this invention, such as Figure 8As shown, the input terminal of the lifting / lowering bar control signal UD is input to the lifting / lowering bar unit 21, and the output terminal is connected to the first input terminal of the reset generation unit 24 to output the lifting bar reset signal. The lifting bar reset unit 21 can be a rising edge detection logic unit R_TRIG. When the lifting / lowering bar control signal UD changes from 0 to 1 (i.e., from lowering the bar to lifting the bar), it outputs a short pulse signal (lifting bar reset signal), resetting the currently selected bar group and the selected adjustment bar, and putting all 3 bar groups and 6 adjustment bars into an unselected state, preparing for lifting the bar to select the lowest bar.

[0124] The input terminal of the bar lowering reset unit 22 receives the bar raising / lowering control signal UD, and the output terminal is connected to the second input terminal of the reset generation unit 24 to output the bar lowering reset signal. The bar lowering reset unit 22 can be a falling edge detection logic unit F_TRIG. When the bar raising / lowering control signal UD changes from 1 to 0 (i.e., from raising the bar to lowering the bar), it outputs a short pulse signal (bar lowering reset signal), resetting the currently selected bar group and the selected adjustment bar, and putting all 3 bar groups and 6 adjustment bars into an unselected state, preparing for the selection of the highest bar during bar lowering.

[0125] The manual judgment unit 23 receives the manual / automatic control mode signal MA at its first input terminal, the value 0 at its second input terminal, and its output terminal is connected to the third input terminal of the reset generation unit 24 to output a manual reset signal. The manual judgment unit 23 can determine whether the manual / automatic control mode signal MA is equal to 0. When MA = 0, i.e., the control rod is in manual control mode, the manual judgment unit 23 outputs a high-level signal; otherwise, it outputs a low-level signal. The manual judgment unit 23 is used to output a manual reset signal when the control rod is in manual control mode, resetting the currently selected rod group and the selected adjustment rod, placing all three rod groups and six adjustment rods in an unselected state, preparing for the next automatic operation to select the highest rod when raising the rod and the lowest rod when lowering the rod.

[0126] The reset generation unit 24 receives a lifting reset signal at its first input terminal, a lowering reset signal at its second input terminal, and a manual reset signal at its third input terminal. Its output terminal outputs a reset signal (RESET) to reset the selection signals of the three rod groups and the six adjusting rods. The reset generation unit 24 can be an OR logic unit, receiving the lifting reset signal, lowering reset signal, and manual reset signal respectively. When all three are 0, the output is 0; otherwise, the output is 1. The reset generation unit 24 ensures that when the control rod changes its lifting / lowering direction, it resets the rod group and adjusting rod selection signals, placing all three rod groups and six adjusting rods in an unselected state, preparing for selecting the highest rod when lowering and the lowest rod when lifting. The reset generation unit 24 also ensures that when the control rod switches from automatic to manual control mode, it resets the rod group and adjusting rod selection signals, placing all three rod groups and six adjusting rods in an unselected state, preparing for selecting the highest rod when lowering and the lowest rod when lifting after the next automatic switch.

[0128] The rod group judgment unit 31 is used to determine whether the regulating rod with the smallest relative rod position data among all regulating rods is located in the target rod group based on the smallest relative rod position data in the target rod group generated by the calculation module 1 and the smallest relative rod position data among all regulating rods, and outputs the judgment result.

[0129] The group selection locking unit 32 is used to receive selection signals from two other rod groups besides the target rod group, and generate a group selection locking signal based on the selection signals;

[0130] The rod group determination unit 33 is used to generate a rod group determination signal based on the received externally input power control system automatic control mode signal, the judgment result generated by the rod group judgment unit 31, and the selection group locking signal generated by the selection group locking unit 32.

[0131] The rod group zeroing unit 34 is used to generate a rod group zeroing signal based on the received externally input target adjustment rod position signal, the target adjustment rod selection signal generated by the rod selection module 1, and the reset signal RESET generated by the reset module 2.

Wherein:

[0134] The first position determination unit 341 of the rod group is used to generate the first position determination signal of the rod group based on the received target adjustment rod position signal input from the outside and the target adjustment rod selection signal generated by the rod selection module 4.

[0135] The first position locking unit 342 of the rod group is used to generate the first position locking signal of the rod group according to the first position determination signal of the rod group and the rod group zeroing signal output by the rod group zeroing signal generation unit 346.

[0136] The second position determination unit 343 of the rod group is used to generate a second position determination signal of the rod group based on the position signal of another adjusting rod in the target rod group other than the target adjusting rod, which is received from an external input, and the adjusting rod selection signal generated by the rod selection module 4 corresponding to the other adjusting rod; the second position locking unit 344 of the rod group is used to generate a second position locking signal of the rod group based on the second position determination signal of the rod group and the rod group zeroing signal output by the rod group zeroing signal generation unit 346.

[0137] The rod group double rod positioning determination unit 345 is used to generate a rod group double rod positioning determination signal based on the rod group first adjustment rod positioning lock signal and the rod group second adjustment rod positioning lock signal;

[0138] The rod group zeroing signal generation unit 346 is used to generate a rod group zeroing signal based on the rod group double rod positioning determination signal and the reset signal RESET generated by the reset module 2.

[0139] As an optional implementation of this invention, the number of group selection modules 3 in this embodiment is three, namely a first group selection module, a second group selection module, and a third group selection module. Combined with... Figure 11 , 12 As shown in Figure 13, the first selection module in this embodiment of the invention includes: a first rod group judgment unit 311, a first selection group locking unit 321, a first rod group determination unit 331, a first rod group first position determination unit 3411, a first rod group first position locking unit 3421, a first rod group second position determination unit 3431, a first rod group second position locking unit 3441, a first rod group double rod position determination unit 3451, a first rod group zeroing signal generation unit 3461, and a first rod group selection unit 351.

[0140] The second selection module in this embodiment of the invention includes: a second rod group judgment unit 312, a second selection group locking unit 322, a second rod group determination unit 332, a second rod group second position determination unit 3412, a second rod group second position locking unit 3422, a second rod group second position determination unit 3432, a second rod group second position locking unit 3442, a second rod group dual rod position determination unit 3452, a second rod group zeroing signal generation unit 3462, and a second rod group selection unit 352.

[0141] The third selection module in this embodiment of the invention includes: a third rod group judgment unit 313, a third selection group locking unit 323, a third rod group determination unit 333, a third rod group third position determination unit 3413, a third rod group third position locking unit 3423, a third rod group third position determination unit 3433, a third rod group third position locking unit 3443, a third rod group double rod position determination unit 3453, a third rod group zeroing signal generation unit 3463, and a third rod group selection unit 353.

[0142] In one embodiment of the present invention, combined with Figure 11 As shown, for the first group selection module:

[0143] The first input terminal of the first rod group judgment unit 311 receives the smallest relative rod position data MI among all adjusting rods, and the second input terminal receives the smallest relative rod position data T1 in the first rod group. The output terminal is connected to the second input terminal of the first rod group determination unit 331. The output terminal of the first rod group judgment unit 311 outputs the judgment result regarding whether the adjusting rod with the smallest relative rod position data is located in the first rod group. Specifically, the first rod group judgment unit 311 can determine whether T1 and MI are equal. When T1 = MI, it outputs a high-level signal 1; when T1 ≠ MI, it outputs a low-level signal 0.

[0144] The first input terminal of the first group selection locking unit 321 receives the selection signal SLT2 for the second rod group, and the second input terminal receives the selection signal SLT3 for the third rod group. Its output terminal is connected to the third input terminal of the first rod group determination unit 331 to output the first group selection locking signal. The first group selection locking unit 321 can be an OR logic unit, receiving SLT2 and SLT3 signals respectively. When both SLT2 and SLT3 are 0, it outputs 0; otherwise, it outputs 1. The first group selection locking unit 321 ensures that both the second and third rod groups are currently unselected, preventing the simultaneous selection of multiple rod groups.

[0145] The first input terminal of the first rod group determination unit 331 receives the automatic control mode signal MA from the externally input power control system. The second input terminal receives the judgment result of whether the minimum relative rod position data adjustment rod is located in the first rod group. The third input terminal is equipped with an inverter to input the inverted first selection group lock signal. The output terminal is connected to the first input terminal (S terminal) of the first rod group selection unit 351 to output the first rod group determination signal. The first rod group determination unit 331 can be an AND logic unit, receiving the automatic control mode signal MA from the power control system, the judgment result of whether the minimum relative rod position data adjustment rod is located in the first rod group, and the inverted first selection group lock signal. When all three are 1, the output is 1; otherwise, the output is 0. The first rod group determination unit 331 ensures that the first rod group is selected only when all three conditions are met simultaneously: the system is in automatic control mode, the adjustment rod with the minimum relative position data is located in the first rod group, and neither the second nor the third rod group is selected.

[0146] The first input terminal of the first position determination unit 3411 for the first rod group receives the first adjustment rod position signal FB1 from an external input, and the second input terminal receives the first adjustment rod selection signal O1 generated by the rod selection module 4. The output terminal is connected to the first input terminal of the first position locking unit 3421 for the first rod group, and is used to output the first adjustment rod position determination signal for the first rod group. The first position determination unit 3411 is an AND logic unit, receiving the first adjustment rod position signal FB1 and the first adjustment rod selection signal O1 respectively. When both are 1, it outputs 1; otherwise, it outputs 0. The first position determination unit 3411 ensures that the first adjustment rod position determination signal is generated only when the first adjustment rod is in the selected state and has moved to its position.

[0147] The first input terminal of the first position locking unit 3421 for the first rod group receives the position determination signal of the first adjusting rod of the first rod group generated by the first position determination unit 3411 for the first rod group. The second input terminal receives the clear signal of the first rod group generated by the clear signal generation unit 3461 for the first rod group. The output terminal is connected to the first input terminal of the first position determination unit 3451 for the first rod group, and is used to output the position locking signal of the first adjusting rod of the first rod group. The first position locking unit 3421 for the first rod group is a reset / set (RS) trigger. It receives the position determination signal of the first adjusting rod of the first rod group and the clear signal of the first rod group. When the position determination signal of the first adjusting rod of the first rod group is high and the clear signal of the first rod group is low, it outputs 1. When the position determination signal of the first adjusting rod of the first rod group is low and the clear signal of the first rod group is low, the output remains 1. When the clear signal of the first rod group is high, the output is 0 regardless of whether the position determination signal of the first adjusting rod of the first rod group is high or low. The first position locking unit 3421 of the first rod group is used to ensure that the first adjusting rod of the first rod group is selected and moved into position, stops the operation of the first adjusting rod of the first rod group, and switches to the operation of the other adjusting rod symmetrical to the first rod group. The information that the first adjusting rod of the first rod group has performed the rod operation can be maintained and recorded by the first adjusting rod position locking signal of the first rod group. After both the symmetrical adjusting rods of the first rod group have moved into position once, the first rod group zeroing signal generation unit 3461 will generate a first rod group zeroing signal to reset the first adjusting rod position locking signal of the first rod group.

[0148] The first input terminal of the first group second position determination unit 3431 receives the fourth adjustment bar position signal FB4 from an external input, and the second input terminal receives the fourth adjustment bar selection signal O4 generated by the selection module 4. The output terminal is connected to the first input terminal of the first group second position locking unit 3441, and is used to output the first group second adjustment bar position determination signal. The first group second position determination unit 3431 is an AND logic unit, receiving the fourth adjustment bar position signal FB4 and the fourth adjustment bar selection signal O4 respectively. When both are 1, it outputs 1; otherwise, it outputs 0. The first group second position determination unit 3411 ensures that the first group second adjustment bar is in the selected state, and only generates the first group second adjustment bar position determination signal when the first group second adjustment bar is moved into position.

[0149] The first input terminal of the first rod group second position locking unit 3441 receives the first rod group second position determination unit 3431's first rod group second adjustment rod position determination signal, and the second input terminal receives the first rod group clear signal generated by the first rod group clear signal generation unit 3461. The output terminal is connected to the second input terminal of the first rod group dual rod position determination unit 3451, and is used to output the first rod group second adjustment rod position locking signal. The first rod group second position locking unit 3441 is a reset / set (RS) trigger, receiving the first rod group fourth adjustment rod position determination signal and the rod group clear signal. When the first rod group fourth adjustment rod position determination signal is high and the first rod group clear signal is low, the output is 1. When the first rod group first adjustment rod position determination signal is low and the first rod group clear signal is low, the output remains 1. When the rod group clear signal is high, the output is 0 regardless of whether the first rod group fourth adjustment rod position determination signal is high or low. The first rod group second position locking unit 3421 is used to ensure that the second adjusting rod of the first rod group is selected and moved into position, stops the selection and operation of the second adjusting rod of the first rod group, and switches to the operation of the other adjusting rod symmetrical to the first rod group. The information that the second adjusting rod of the first rod group has performed the rod operation can be maintained and recorded by the first rod group second adjusting rod position locking signal. After both symmetrical adjusting rods of the first rod group have moved into position once, the first rod group zeroing signal generation unit 3461 will generate a first rod group zeroing signal to reset the first rod group second adjusting rod position locking signal.

[0150] The first input terminal of the first rod group dual-rod positioning determination unit 3451 receives the first rod group first positioning locking unit 3421's first rod group first adjusting rod positioning locking signal, and the second input terminal receives the first rod group second adjusting rod positioning locking signal generated by the first rod group second positioning locking unit 3441. The output terminal is connected to the first input terminal of the first rod group zeroing signal generation unit 3461, and is used to output the first rod group dual-rod positioning determination signal RST1. The first rod group dual-rod positioning determination unit 3451 is an AND logic unit, receiving the first rod group first adjusting rod positioning locking signal and the first rod group second adjusting rod positioning locking signal. When both are 1, the output is 1; otherwise, it is 0. The first rod group dual-rod positioning determination signal generated by the first rod group dual-rod positioning determination unit 3451 indicates that both adjusting rods in the first rod group have performed one rod movement operation.

[0151] The first input terminal of the first rod group zeroing signal generation unit 3461 receives the first rod group dual-rod positioning confirmation signal generated by the first rod group dual-rod positioning confirmation unit 3451. The second input terminal receives the reset signal RESET generated by the reset module 2. The first output terminal is connected to the second input terminal (R terminal) of the first rod group selection unit 351, the second output terminal is connected to the second input terminal of the first rod group first positioning locking unit 3421, and the third output terminal is connected to the second input terminal of the first rod group second positioning locking unit 3441, used to output the first rod group zeroing signal. The first rod group zeroing signal generation unit 3461 is an OR logic unit, receiving the first rod group dual-rod positioning confirmation signal and the reset signal RESET. When both are 0, the output is 0; otherwise, it is 1. The first rod group zeroing signal generation unit 3461 is used to send a first rod group zeroing signal to the first rod group selection unit 351 to reset the first rod group selection signal SLT1 when both adjusting rods of the first rod group have performed a rod operation (i.e., the first rod group double rod position confirmation signal is 1), or when the control rod changes the lifting / lowering rod direction or the control rod is in manual control mode (i.e., the reset signal RESET is 1); send a first rod group zeroing signal to the first rod group first position locking unit 3421 to reset the first adjusting rod position locking signal of the first rod group; and send a first rod group zeroing signal to the first rod group second position locking unit 3441 to reset the second adjusting rod position locking signal of the first rod group, thus preparing for the next automatic lifting / lowering rod selection.

[0152] The first input terminal of the first rod group selection unit 351 receives the first rod group determination signal generated by the first rod group determination unit 331, and the second input terminal receives the first rod group clear signal generated by the first rod group clear signal generation unit 3461. The output terminal outputs the first rod group selection signal SLT1. The first rod group selection unit 351 is an RS flip-flop; it outputs the first rod group selection signal SLT1 when the first rod group determination unit 331 sends the rod group determination signal and the first rod group clear signal generation unit 3461 does not send the first rod group clear signal.

[0178] In one embodiment of the present invention, combined with Figure 15 As shown, for the first bar selection module:

[0179] The first input terminal of the first rod group double rod positioning judgment unit 4011 receives the first rod group double rod positioning confirmation signal RST1 generated by the group selection module 3, the second input terminal receives the value 0, and the output terminal is connected to the second input terminal of the rod group preparation unit 4021 to output the first rod group double rod positioning judgment signal. Specifically, the first rod group double rod positioning judgment unit 4011 can determine whether RST1 and 0 are equal, that is, whether RST1 is low. When RST1 is low, it outputs 1, indicating that the first and fourth adjusting rods of the first rod group have not moved into position. When RST1 is high, it outputs 0, indicating that both the first and fourth adjusting rods of the first rod group have moved into position.

[0180] The first input terminal of the first rod group preparation unit 4021 receives the first rod group selection signal SLT1 generated by the selection module 3, and the second input terminal receives the first rod group double rod positioning judgment signal. The first output terminal is connected to the first input terminal of the first single rod preparation unit 40411, and the second output terminal is connected to the second input terminal of the first rod group second single rod preparation unit 40412, used to output the first rod group preparation signal. The first rod group preparation unit 4021 can be an AND logic unit, inputting SLT1 and the first rod group double rod positioning judgment signal to ensure that rod selection can only be performed when the first rod group is currently selected and the first and fourth adjusting rods have not moved into position.

[0181] The first input terminal of the single-bar judgment unit 4031 for the first bar group receives the relative bar position data IX1 of the first adjusting bar, and the second input terminal receives the relative bar position data IX4 of the fourth adjusting bar. The output terminal is connected to the second input terminal and the first input terminal of the second single-bar preparation unit 40412 for the first bar group, respectively, to output a first relative bar position comparison signal. The single-bar judgment unit 4031, by inputting IX1 and IX4, can determine whether IX1 is less than or equal to IX4. When IX1 ≤ IX4, the single-bar judgment unit 4031 outputs a high level (1); otherwise, it outputs a low level (0). The single-bar judgment unit 4031 can determine which of the first and fourth adjusting bars in the first bar group has a lower relative bar position.

[0182] The first input terminal of the first single-bar preparation unit 40411 for the first bar group receives the first bar group preparation signal, and the second input terminal receives the first relative bar position comparison signal. The output terminal is connected to the first input terminal of the first double-bar action locking unit 40811 for the first bar group, and is used to output the first single-bar preparation signal for the first bar group. The first single-bar preparation unit 40411 can be an AND logic unit, receiving the first bar group preparation signal and the first relative bar position comparison signal. It outputs 1 only when both the first bar group preparation signal and the first relative bar position comparison signal are 1; otherwise, it outputs 0. The first single-bar preparation unit 40411 ensures that the first bar group is currently selected and the first and fourth adjusting bars are not in position, and IX1≤IX4, before outputting the single-bar preparation signal for the first adjusting bar of the first bar group.

The first rod group second single rod preparation unit 40412 can be an AND logic unit. It receives the inverted first relative rod position comparison signal and the first rod group preparation signal. It outputs 1 only when the first rod group preparation signal is 1 and the first relative rod position comparison signal is 0; otherwise, it outputs 0. The first rod group second single rod preparation unit 40412 can ensure that the first rod group is currently selected and the first and fourth adjusting rods are not in position, and IX1 > IX4, before outputting the single rod preparation signal for the fourth adjusting rod of the first rod group.

The output terminal is connected to the first input terminal of the first rod group single-rod reset unit 4061, and is used to output the first rod group selection judgment signal. The first rod group selection judgment unit 4051 can determine whether SLT1 and 0 are equal, that is, whether SLT1 is low. When SLT1 is low, it outputs 1, indicating that the first rod group is not selected. When SLT1 is high, it outputs 0, indicating that the first rod group is selected.

[0185] The first input terminal of the first rod group single rod reset unit 4061 receives the first rod group selection judgment signal, and the second input terminal receives the reset signal RESET1 generated by the reset module 2. The first output terminal is connected to the first input terminal of the first rod group first double rod action unlocking unit 40711, the second output terminal is connected to the first input terminal of the first rod group second double rod action unlocking unit 40712, the third output terminal is connected to the first rod group first single rod clearing unit 41211, and the fourth output terminal is connected to the first rod group second single rod clearing unit 41212, which is used to output the first rod group single rod reset signal RESET1.

The output terminal is connected to the second input terminal of the first group second double-bar action locking unit 40812, and is used to output the first group second double-bar action unlocking signal. The first group second double-bar action unlocking unit 40712 can be an OR logic unit, receiving the first group second single-bar reset signal, the first group double-bar positioning confirmation signal RST1, and the first group first double-bar action locking signal Q1. When all three are 0, the output is 0; otherwise, it is 1.

The first double-bar action locking unit 40811 of the first bar group can be an RS flip-flop, receiving the first single-bar preparation signal and the first double-bar action unlock signal of the first bar group. When the first single-bar preparation signal of the first bar group is detected to be high, it outputs the first double-bar action locking signal Q1; when the second double-bar action unlock signal Q4 of the first bar group is detected to be high, it clears the output terminal to zero. First, the first double-bar action locking unit 40811 of the first bar group is used to ensure that when the direction of the control bar's lifting / lowering bar changes, or when the control bar is in manual control mode, or when the first bar group is not selected (i.e., when the single-bar reset signal RESET1 is 1), the first double-bar action locking signal Q1 of the first bar group is cleared to prepare for reselection of the bar (lifting the bar to the highest position, lowering the bar to the lowest position). Secondly, the first double-bar action locking unit 40811 of the first bar group is used to ensure that when both the first and fourth adjusting bars of the first bar group are in position (i.e., when the first bar group double-bar positioning confirmation signal RST1 is 1), the first double-bar action locking signal Q1 of the first bar group is cleared to prepare for reselection of the bar (lifting the bar to the highest position, lowering the bar to the lowest position). Thirdly, the first double-bar action locking unit 40811 of the first bar group is used to ensure that when the second double-bar action unlocking signal Q4 of the first bar group is high, the first double-bar action locking signal Q1 of the first bar group is cleared to prevent simultaneous selection of both adjusting bars in the first bar group.

[0189] The first input terminal of the first group second double-bar action locking unit 40812 receives the first group second single-bar preparation signal, and the second input terminal receives the first group second double-bar action unlock signal.

The first group second double-bar action locking unit 40812 can be an RS flip-flop, receiving the first group second single-bar preparation signal and the first group second double-bar action unlock signal. When the first group second single-bar preparation signal is detected to be high, it outputs the first group second double-bar action locking signal Q4; when the first group first double-bar action unlock signal Q1 is detected to be high, the output terminal is cleared to zero. First, the first-group second double-bar action locking unit 40812 ensures that when the control bar lifting / lowering direction changes, or the control bar is in manual control mode, or the first group of bars is not selected (i.e., when the single-bar reset signal RESET1 is 1), the first-group second double-bar action locking signal Q4 is cleared to prepare for reselection (lifting the bar to the highest position, lowering the bar to the lowest position). Second, the first-group second double-bar action locking unit 40812 ensures that when both the first and fourth adjusting bars of the first group are in position (i.e., when the first group double-bar positioning confirmation signal RST1 is 1), the first-group second double-bar action locking signal Q4 is cleared to prepare for reselection (lifting the bar to the highest position, lowering the bar to the lowest position). Third, the first-group second double-bar action locking unit 40812 ensures that when the first group first double-bar action unlocking signal Q1 is high, the first-group second double-bar action locking signal Q4 is cleared to prevent simultaneous selection of both adjusting bars in the first group.

The first single-bar selection trigger unit 40911 is a rising edge detection logic unit R_TRIG. When the first double-bar action lock signal of the first rod group changes from 0 to 1, it outputs a short pulse signal. The first single-bar selection trigger unit 40911 ensures that the first rod group is currently selected, and the first and fourth adjusting bars are not in position, and IX1≤IX4, outputting the first single-bar selection trigger signal of the first rod group only once, preventing repeated selection of the first adjusting bar of the first rod group.
