For example, as shown in FIG. 3, FIG. 3 is a schematic diagram of the stop judgment of the high temperature gas-cooled reactor control rods in the embodiment of the present disclosure, wherein the rod lifting/lowering command RCL is used to indicate whether the control rods are to be raised or lowered, When RCL is 1, it means that the control rod is raised or lowered. When RCL is 0, it means that the control rod is raised or lowered. There is no need to judge the stop of the control rod. The pulse readback value BP is the subtraction The value obtained after reading back the pulse number of the controller operation module SUB (the subtraction operation module is the above-mentioned control rod drive module), select the module SEL, and when RCL is 1, the output is the third pin of the input terminal When RCL is 0, the output is the value of the second pin of the input terminal. At this time, the number of pulses at the two input terminals of the subtraction module SUB is the same, and no subsequent judgment is made. The multiplication module MUL is used to set the displacement value according to LP and pulse equivalent value PE calculate the set pulse number corresponding to the set displacement value, and the absolute value operation module ABS is used to take the absolute value of the pulse number of the subtraction operation module SUB, because when the control rod is lowered, The result of the subtraction operation module SUB is a negative number, which needs to be judged and calculated after the absolute value is taken by the absolute value operation module ABS. When it is set to 1, the STP signal will control the stepper motor to stop, and the control rod will be set to stop.

In the embodiment of the present disclosure, taking the lifting operation of the control rod as an example, at this time, the RCL command is set to 1, and the nuclear power instrument control system (Distributed Control System, DCS) sends out pulses to control the stepping motor to lift the control rod, and The sent pulses are used to read back BP. Among the two inputs of the control rod drive module (subtraction module) SUB, the pulse number at the upper end continues to increase, and the pulse number at the input end of BP is read back as the second pulse number, and the lower end is selected. The module SEL locks the number of pulses at the moment when the rod lifting command RCL becomes 1. This pulse number can be used as the first pulse number, and the second pulse number and the first pulse number are calculated by the subtraction module SUB to obtain the second pulse The number of difference pulses between the number and the first pulse number, input the difference pulse number to the absolute value calculation module ABS for absolute value processing, and the obtained pulse number output by the absolute value calculation module is the rising operation of the control rod The actual pulse number corresponding to the generated actual displacement value, and the multiplication module MUL calculates the product value of the set displacement value LP and the pulse equivalent value PE as the set pulse number, and the actual pulse output by the absolute value operation module ABS The number and the set pulse number output by the multiplication module MUL are compared in the function block ≥. When the actual pulse number is greater than or equal to the multiplication module, it indicates that the actual displacement value is greater than or equal to the set displacement value, and the rod will be raised/lowered in place. The signal STP is set to one, at this time, the STP signal will control the stepper motor to stop, and the control rod will be set to stop.

In some other embodiments, the function module = as shown in Figure 3 can also be set, and the set displacement value LP can be set to -1 in an emergency, and it can not be limited by the stop signal, so that the emergency response can be realized. The flexible control of the rise or fall of the control rod ensures the normal operation of the reaction of the high temperature gas-cooled reactor.

In this embodiment, since the pulse readback value signal BP is read back synchronously when the stepper motor control module sends out the pulse signal, the signal is not transmitted through the inter-station reference point, so as to avoid the problem of signal lag and effectively reduce the control The deviation between the actual displacement of the rod and the displacement set value effectively improves the accuracy of the displacement control of the control rod.

In this embodiment, by obtaining the set pulse number corresponding to the set displacement value of the control rod, the actual pulse number corresponding to the actual displacement value of the control rod is determined, and the stop signal is generated according to the actual pulse number and the set pulse number, wherein, The stop signal is used to set the control rod to a static state, which can control the movement state of the control rod through the number of pulses, reduce the error between the actual displacement value and the set displacement value, and effectively improve the displacement control accuracy of the control rod. According to the first pulse number and the second pulse number, when determining the actual pulse number, the difference pulse number between the second pulse number and the first pulse number can be determined, and the difference pulse number can be used as the actual pulse number, so that the pulse number can be determined according to the pulse number The change value of the control rod determines the more accurate actual pulse number, because the actual pulse number corresponds to the actual displacement of the control rod, so that the accurate acquisition of the actual displacement value of the control rod can be realized. When in-position judgment, the accuracy of control rod in-position judgment can be effectively improved.
