Description

Technical Field

[0001] The present invention relates to the technical field of reactor engineering, and particularly to a method and system for processing the signal of passing balls of a ball counter in a high-temperature gas-cooled reactor. Background Art

[0002] The fuel handling system is an important system connected to the primary loop of the reactor, mainly performing functions such as loading new fuel into the core, unloading spent fuel from the core, recycling fuel elements back to the core, stopping the reactor for unloading, emptying the core, and refueling. The counter is an important process control device in the fuel handling system, mainly used to detect the passing information of fuel balls and graphite balls in the stainless steel pipeline and provide the passing ball information to the upper-level control system. The counter has the functions of single-direction counting and two-way counting, and can count both whole balls and broken balls.

Since the fuel balls and graphite balls may become irregular in shape due to various reasons (such as wear, deformation, etc.) when passing through the stainless steel pipeline, this may cause the existing counters to miss or misrecord when detecting whole balls and broken balls.

[0065] Embodiment 1

[0066] Referring to Figures 1-3 , an embodiment of the present invention provides a method for processing the ball-passing signal of a high-temperature gas-cooled reactor ball-passing counter. As shown in Figure 1 , Figure 2, it includes the following steps:

[0067] S1: Set the output frequency and generate an excitation signal through a sine wave signal.

[0068] In the embodiment of the present application, as shown in Figure 2 , the schematic diagram of the model of the ball-passing counter test bench mainly consists of an excitation signal unit, a differential amplification unit, a signal demodulation unit, a filter amplification unit, an AD acquisition unit, a main control chip, and an output unit, and realizes the program-controlled setting of parameters through the program-controlled potentiometer MCP41HV51.

[0069] In the embodiment of the present application, setting the output frequency and generating an excitation signal through a sine wave signal includes the following steps:

[0070] The main control chip XC7Z020 initializes the DDS chip AD9837, the sampling chip AD7606, and the program-controlled potentiometer MCP41HV51, and sets default parameters to ensure the normal operation of each component.

[0071] The main control chip XC7Z020 configures the DDS chip AD9837, sets the initial sine wave frequency and other parameters, generates an excitation signal, and outputs it to the counter coil after conditioning and amplification.

[0072] In the embodiment of the present application, the master control chip XC7Z020 controls the DDS chip AD9837 to output a sine signal, which is conditioned and amplified and then the excitation signal is output to two groups of coils of the counter.

[0073] S2: Based on the excitation signal, process the ball passing signal induced by the coil to obtain a preliminarily processed ball passing waveform;

[0074] In the embodiment of the present application, processing the ball passing signal induced by the coil includes the following steps:

[0075] When the ball passes through the magnetic field excited by the excitation signal, two groups of coils sense a small current change. The first coil senses the first original ball passing signal S1 and the second coil senses the second original ball passing signal S2.

[0076] Perform differential operation, demodulation, and filter amplification on the original ball passing signals (S1 and S2) to improve the signal-to-noise ratio and extract a clear ball passing waveform. This step ensures the quality of the basic data for subsequent analysis.

[0077] S3: Based on the preliminarily processed ball passing waveform, by programmatically adjusting the parameters of the ball passing signal, obtain an optimized and adjusted ball passing waveform;

[0078] In the embodiment of the present application, the function of programmatically setting parameters is jointly realized by the master control chip XC7Z020, the DDS chip AD9837, the sampling chip AD7606, and the programmable potentiometer MCP41HV51.

[0079] In the embodiment of the present application, the programmed content includes programmatically adjusting the frequency of the signal output by the DDS chip through XC7Z020, sampling S1, S2, the differential amplification signal, and the filter amplification signal through AD7606, and controlling MCP41HV51 through XC7Z020 according to the magnitude of the sampling value to adjust the excitation signal, the balance point of S2, the differential amplification multiple, and the filter amplification multiple to obtain the best ball passing waveform.

[0080] S4: By analyzing the optimized and adjusted ball passing waveform, identify the type and speed range of the ball passing, and output the complete ball passing information.

[0081] In the embodiment of the present application, the analysis and judgment of the ball passing waveform are jointly performed according to the shape, peak value, and pulse width of the ball passing waveform. As Figure 3The four ball-passing waveforms shown. Among them, the forward and reverse ball-passing can be judged by the shape of the ball-passing waveform. The peak value of the ball-passing waveform gradually decreases as the ball-passing volume decreases and also gradually decreases as the ball-passing speed slows down. Therefore, it is impossible to judge whether it is a slow ball-passing or a broken ball-passing only by the peak value. At this time, the pulse width information of the ball-passing waveform is added, and the function of the peak value of the ball-passing waveform changing with the pulse width obtained by data fitting is used to calculate the integrity of the actual ball-passing, so as to effectively distinguish the complete information of the ball-passing at different speeds.

[0082] In the embodiment of the present application, if it is identified as a whole ball or a 2 / 3 broken ball, the system will determine it as a valid ball, control the optocoupler G3VM to output a contact signal, notify relevant external devices to respond (such as recording and counting, alarming, etc.), and save the waveform and its related data to the SD card.

[0083] In the embodiment of the present application, if it is identified as a 1 / 3 broken ball or other non-standard waveforms, the system will determine it as an invalid ball, not count it, not output a contact signal, but still may store the waveform according to the setting for further analysis.

[0084] In the embodiment of the present application, the standard for determining a whole ball is that the shape is complete and regular, the peak value is high, and the pulse width is long.

[0085] In the embodiment of the present application, the standard for determining a 2 / 3 broken ball is that the shape is relatively complete but irregular, the peak value is medium, and the pulse width is moderate.

[0086] In the embodiment of the present application, the standard for determining a 1 / 3 broken ball is that the shape is very irregular, the peak value is low, and the pulse width is short, and it is usually not counted as a valid ball.

[0087] In the embodiment of the present application, the ball-passing waveform is sampled by AD7606 and input into the main control chip XC7Z020 for analysis and processing, and it is judged whether it is a ball-passing. According to the judgment result, the optocoupler G3VM is controlled to output a contact signal. The main control chip XC7Z020 also stores the ball-passing waveform to the SD card for subsequent retrospective analysis.

[0088] In the embodiment of the present application, the storage of the ball-passing waveform is to set a suitable trigger threshold according to the size of the background noise when there is no ball-passing. This threshold is slightly higher than the background noise. Therefore, under this threshold, the waveforms of the balls judged to be less than 2 / 3 will usually be stored to the SD card. By storing more ball-passing waveforms, more ball-passing information can be recorded, which is beneficial to the retrospective analysis in case of missed recording or misrecording.

[0089] It should be noted that the main function of the trigger threshold is to filter background noise and start waveform acquisition, but it also indirectly affects which waveforms will be stored in the SD card. The distinction of over-ball types depends on the comprehensive analysis of characteristic parameters such as the shape, peak value, and pulse width of the waveforms. Therefore, the trigger threshold is not only a part of the storage decision but also a key link in the entire over-ball event recognition and classification process. It ensures that the system can not only capture important over-ball events but also accurately distinguish different types of over-balls.

[0090] In the embodiment of the present application, the over-ball waveform analysis can identify the ball speed range of 0.01 m / s - 10 m / s, and the identified over-ball types include whole balls and 2 / 3 broken balls (should be counted), 1 / 3 broken balls (not counted);

[0091] This embodiment also provides an over-ball signal processing system for a high-temperature gas-cooled reactor over-ball counter, including:

[0092] An excitation signal generation module, used to set the output frequency and generate an excitation signal through a sine wave signal;

[0093] An over-ball signal processing module, used to process the over-ball signal induced by the coil based on the excitation signal to obtain a preliminarily processed over-ball waveform;

[0095] An over-ball information recognition module, used to analyze the optimized and adjusted over-ball waveform to identify the over-ball type and speed range and output the complete over-ball information.

[0096] Furthermore, it further includes:

[0097] A memory, used to store programs;

[0098] A processor, used to load the program to execute the over-ball signal processing method of the high-temperature gas-cooled reactor over-ball counter.

[0099] This embodiment also provides a computer-readable storage medium, which stores a program, and when the program is executed by a processor, it implements the over-ball signal processing method of the high-temperature gas-cooled reactor over-ball counter.

[0100] The storage medium proposed in this embodiment and the over-ball signal processing method of the high-temperature gas-cooled reactor over-ball counter proposed in the above embodiment belong to the same inventive concept. The technical details not described in detail in this embodiment can be referred to the above embodiment, and this embodiment has the same beneficial effects as the above embodiment.

Of course, it can also be implemented by hardware, but in many cases, the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product can be stored in a computer-readable storage medium, such as a floppy disk, read-only memory (ROM), random access memory (RAM), flash memory, hard disk, or optical disc of a computer, etc., including several instructions to enable a computer device (which can be a personal computer, server, or network device, etc.) to execute the methods of various embodiments of the present invention.
