[0031] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] With technological advancements, accelerators are developing towards high-intensity and high-power accelerators, with total beam powers reaching the megawatt (MW) range. All proton and heavy-ion accelerators currently in operation and under construction worldwide incorporate a proton or heavy-ion linear accelerator (LINAC) as the primary accelerator or injector. This is because LINACs offer a more compact structure and higher acceleration efficiency. Furthermore, the incorporation of low-temperature superconducting technology in superconducting LINACs allows for higher accelerating electric field gradients, significantly reducing the overall length of the LINAC. Against this backdrop, beam diagnostic systems for high-intensity and high-power proton and heavy-ion LINACs and their associated technologies have assumed significant importance.

[0033] Existing beam position monitoring systems primarily consist of a beam position detector and connecting cables, as well as multiple front-end analog amplifiers, a multi-channel analog-to-digital converter, and a main control module. The beam position detector is used to detect beam position and phase. When the beam passes through the beam position detector, it generates an analog signal on its plates. The signal is typically composed of four plates. The beam's horizontal and vertical positions, as well as its phase, can be calculated based on the signal intensity generated by the four plates in response to beam current. The connecting cable transmits the analog signal generated by the beam position detector to the front-end analog amplifier. The front-end analog amplifier amplifies or attenuates the analog signal generated by the beam position detector for subsequent analog-to-digital conversion. The front-end analog amplifier receives the analog signal transmitted by the connecting cable and transmits the processed analog signal to the analog-to-digital converter. The analog-to-digital converter converts the analog signal into a digital signal for processing and analysis by the main control module. The analog-to-digital converter receives the amplified or attenuated analog signal from the front-end analog amplifier, converts it into a digital signal, and then transmits it to the main control module. The main control module is responsible for processing the digital signals converted by the analog-to-digital converter (A / D converter), performing data analysis and variable control, and outputting the final beam position measurement results. The main control module receives the digital signals from the A / D converter, processes them through algorithms, and outputs information such as beam position and phase. It also controls the operation of the entire monitoring system. This enables analysis and processing of beam position and phase signals, making it a crucial component of the accelerator beam monitoring system. Therefore, the health of the entire signal transmission link between the beam position detector and the main control module, as well as the reliability of the self-test results of the signal transmission path between each detector plate and the beam position monitoring system, are particularly important to the beam position monitoring system. Each plate of the beam position detector is connected, in sequence, to a front-end analog amplifier and an A / D converter, ultimately to the main control module. The sensing signal generated by each plate is transmitted via a connecting cable to the front-end analog amplifier, then to the A / D converter, and finally to the main control module, forming a signal transmission path.

[0034] Figure 14 is a flow chart of a self-test method of a beam position monitoring system provided according to an embodiment of the present invention.

[0035] like Figure 1 As shown, the self-test method of the beam position monitoring system provided in an embodiment of the present invention can be performed by the beam position monitoring system, and the method includes the following steps:

[0036] Step 101: If the signal acquisition module of the beam position monitoring system receives self-test trigger information, it acquires a self-test signal.

[0037] In one embodiment of the present invention, a self-test signal is input from a self-test port of the beam position monitoring system. This is a manually configured test signal used to simulate a beam signal under actual operating conditions, i.e., a simulated signal, to facilitate functional verification of various components of the beam position monitoring system. The beam position monitoring system begins receiving the self-test signal from the self-test port upon detecting an internal or external self-test trigger, such as a user operation, a predetermined self-test time, system power-up, or an abnormality detected by the beam position monitoring system.

[0038] Step 102 : Input the self-test signal into the analog-to-digital converter of the beam position monitoring system to determine whether the analog-to-digital converter operates normally.

[0039] In one embodiment of the present invention, after receiving the self-test signal, the beam position monitoring system will input the self-test signal into the analog-to-digital converter. The task of the analog-to-digital converter is to convert the self-test signal into a digital signal, so that the beam position monitoring system can check whether the digital signal output by the analog-to-digital converter meets expectations, thereby determining whether the analog-to-digital converter is working normally.

[0040] Step 103 , when the analog-to-digital converter is operating normally, input the self-test signal to each plate of the beam position detector of the beam position monitoring system to determine whether the signal transmission path formed between each plate of the beam position detector and the beam position monitoring system is operating normally.

[0041] In one embodiment of the present invention, multiple signal transmission paths are formed between each electrode plate of the beam position detector and the beam position monitoring system. When the analog-to-digital converter is operating normally, a self-test signal is input into each electrode plate of the beam position detector. Based on the corresponding induction signal generated by the adjacent electrode plates of the beam position detector in response to the self-test signal, it is judged whether the signal transmission path formed between the adjacent electrode plates of the detector and the beam position monitoring system is operating normally.

[0042] Step 104 , outputting a self-test result when the signal transmission paths formed between the plates of the beam position detector and the beam position monitoring system are operating normally;

[0043] Among them, the beam position monitoring system includes multiple front-end analog amplifiers, multi-channel analog-to-digital converters and a main control module. Each electrode is connected to a front-end analog amplifier, an analog-to-digital converter in turn, and finally connected to the main control module to form a signal transmission path.

[0044] In one embodiment of the present invention, the beam position monitoring system includes multiple front-end analog amplifiers, multiple analog-to-digital converters, and a main control module. Each plate is sequentially connected to a front-end analog amplifier, a single analog-to-digital converter, and ultimately to the main control module, forming a signal transmission path. After a self-test signal is input to each plate of the beam position detector, the system detects the induced signals generated by each plate relative to its neighboring plates to confirm that the signal transmission paths between each plate of the beam position detector and the beam position monitoring system are functioning properly. The self-test process is then completed, and the self-test results are output.

[0045] For example, the self-test result may be notified to the user through user interface display, log recording, or other means.

[0046] In summary, according to the technical solution provided by the embodiment of the present invention, after receiving the self-test trigger information, the signal transmission path formed between the analog-to-digital converter and each electrode of the beam position detector and the beam position monitoring system is self-tested in turn to determine whether it is working normally, and finally the self-test results are output. This not only ensures the reliability and accuracy of the beam position monitoring system, but also eliminates the need for frequent manual inspection and testing by maintenance personnel, thereby reducing labor costs.

[0047] Furthermore, the self-test signal is inputted into the analog-to-digital converter of the beam position monitoring system to determine whether the analog-to-digital converter is working properly, including:

[0048] inputting a self-test signal to a multi-channel analog-to-digital converter of a beam position monitoring system;

[0049] Transmitting the digital signal output by each analog-to-digital converter to the main control module of the beam position monitoring system, obtaining the channel amplitude quantization signal output by the main control module corresponding to the digital signal output by each analog-to-digital converter; checking whether the channel amplitude quantization signal corresponding to the digital signal output by each analog-to-digital converter is greater than a preset first threshold;

[0050] If the amplitude quantization signals of all channels are greater than the first threshold, it is determined that each analog-to-digital converter is working normally; if the channel amplitude quantization signal corresponding to the digital signal output by at least one analog-to-digital converter is less than or equal to the first threshold, it is determined that the analog-to-digital converter of the beam position monitoring system is working abnormally.

[0051] Specifically, the beam position monitoring system has multiple analog-to-digital converters (ADCs), and self-test signals are input into each ADC in the system. These ADCs convert analog signals into digital signals for further processing. After processing the self-test signals, each ADC outputs a corresponding digital signal. These digital signals are then transmitted to the main control module of the beam position monitoring system. The main control module receives and processes the signals from all ADCs and outputs a channel amplitude quantization signal corresponding to each ADC. The beam position monitoring system checks the value of each channel amplitude quantization signal to determine whether they are all greater than a preset first threshold. This first threshold can be determined based on system performance, historical data, self-test signals, or the expertise and experience of technicians. If the channel amplitude quantization signals output by all ADCs are greater than the first threshold, it can be determined that all ADCs are functioning properly, as they are all able to correctly convert the self-test signals and maintain accuracy. If the channel amplitude quantization signal output by at least one ADC is less than or equal to the first threshold, the system determines that at least one ADC is malfunctioning. This may mean that the ADC is not converting the signal correctly or has another fault. If an ADC is detected to be operating abnormally, the system may trigger an alarm, log the error message, and take further diagnostic measures, such as recalibrating, replacing the faulty ADC, or performing other necessary maintenance. The channel amplitude quantization signal is obtained by the main control module after filtering, down-converting, and normalizing the digital signal.

[0052] Exemplarily, by setting a relay, the self-test signal provided by the signal source is directly input into the multi-channel analog-to-digital converter through the self-test port without passing through the beam position detector, and then the digital signal output by the analog-to-digital converter is transmitted to the main control module of the beam position monitoring system, and the main control module outputs the channel amplitude quantization signal corresponding to the digital signal output by each analog-to-digital converter. Check all channel amplitude quantization signals to determine whether the amplitude quantization signal of each channel exceeds the preset first threshold. If the amplitude quantization signal of each channel exceeds the first threshold, it is determined that the analog-to-digital converter of the beam position monitoring system is working normally. If there is at least one channel amplitude quantization signal less than the first threshold, it is determined that the analog-to-digital converter of the beam position monitoring system is working abnormally, and it may be necessary to trigger an alarm, record error information, and take further diagnostic measures, such as recalibration, replacement of the faulty analog-to-digital converter, or other necessary maintenance operations. Figure 2 As shown, Figure 2Figure 2 is a schematic diagram of a beam position monitoring system provided by an embodiment of the present invention. The analog-to-digital converter (ADC Check) performs a self-test, i.e., ADC Check, on the corresponding channel amplitude quantization signals corresponding to the multiple analog-to-digital converters, respectively, output by channels A, B, C, and D. The channel amplitude quantization signal output by each channel is compared with a first threshold (i.e., Threshold 1).

[0053] Figure 2 In the example, Att. = -30dB means the signal is attenuated by 30dB. In signal processing, a negative attenuation value usually means the signal is attenuated rather than amplified. Here, "-30dB" means the signal strength is attenuated by 30 decibels.

[0054] Att. = 0dB means that the signal is neither attenuated nor amplified, and the signal strength remains unchanged. An attenuation value of 0dB means that the signal is transmitted and processed at its original strength.

[0055] Exemplarily, the beam position monitoring system has four signal transmission paths, and correspondingly there are also four channel amplitude quantization signals.

[0056] In summary, according to the technical solutions provided by the embodiments of the present invention, the beam position monitoring system can automatically detect and verify the operating status of each analog-to-digital converter, ensuring that the entire system can provide accurate measurement results during actual operation. This self-checking mechanism is crucial for maintaining the reliability and stability of the system.

[0057] Furthermore, when the analog-to-digital converter is operating normally, a self-test signal is input to each plate of the beam position detector of the beam position monitoring system to determine whether a signal transmission path formed between each plate of the beam position detector and the beam position monitoring system is operating normally, including:

[0058] When the analog-to-digital converter is operating normally, the self-test signal is sequentially inputted into the left plate, the upper plate, the right plate and the lower plate arranged in circumferential order on the beam position detector;

[0059] Acquire the sensing signals generated by the other plates adjacent to the plate inputting the self-test signal; input the sensing signals into the corresponding analog-to-digital converters and transmit them to the main control module of the beam position monitoring system;

[0060] The main control module outputs the channel amplitude quantization signal corresponding to each sensing signal;

[0061] Check whether the channel amplitude quantization signal corresponding to each sensing signal is greater than a preset second threshold;

[0062] If the channel amplitude quantization signals corresponding to all sensing signals are greater than the second threshold, it is determined that the beam position detector is working normally; if the channel amplitude quantization signal corresponding to at least one sensing signal is less than or equal to the second threshold, it is determined that there is an abnormality in the signal transmission path formed between the electrode plate of the beam position detector involving the channel amplitude quantization signal and the beam position monitoring system.

[0063] Specifically, the beam position detector is circumferentially arranged with a left plate, an upper plate, a right plate, and a lower plate. When the analog-to-digital converter is operating normally, the self-test signal is sequentially input into the four plates of the beam position detector (i.e., the left plate, the upper plate, the right plate, and the lower plate). When the self-test signal is input into a plate, an induction signal is generated by the adjacent plate due to physical effects (such as electromagnetic induction). The induction signal is an analog signal, which is transmitted to the corresponding analog-to-digital converter, where it is converted into a digital signal. The converted signal is then transmitted to the main control module. The main control module then receives the digital signals from the multiple analog-to-digital converters and outputs a channel amplitude quantization signal corresponding to each induction signal. Each channel amplitude quantization signal is compared with a preset second threshold. The preset second threshold can be determined based on system performance, historical data, or self-test signals, or based on the technical expertise and experience of the technician. If all channel amplitude quantization signals are greater than the second threshold, the signal transmission path between each detector plate and the beam position monitoring system is considered to be functioning properly, as all channel amplitude quantization signals reach a certain intensity. If any channel amplitude quantization signal is less than or equal to the second threshold, a problem is considered to exist in the signal transmission path between the beam position detector plate and the beam position monitoring system, involving that channel's amplitude quantization signal, requiring further inspection and repair.

[0064] For example, Figure 2 As shown, checking the beam position detector is to check whether the installation between the plates has reached the installation accuracy and whether the signal connection cables are in good contact. For details, please refer to the following methods:

[0065] 1. A relay is used to directly input the self-test signal from port A to the left plate of the beam position detector. The sensing signals from the adjacent upper and lower plates are then sequentially transmitted through their corresponding front-end analog amplifiers, analog-to-digital converters, and main control modules before being input to the corresponding channels B (for example, the upper plate corresponds to channel B) and D (for example, the lower plate corresponds to channel D). The channel amplitude quantization signals VB and VD output by channels B and D are determined to be greater than a second threshold (i.e., Threshold 2). The self-test results are displayed directly on the user interface. If both values are greater than the preset second threshold, the self-test is indicated as passed, indicating that the coupling between the left plate and the upper and lower plates, as well as the signal transmission path between the left plate and the beam position monitoring system, is adequate. If at least one value is less than or equal to the second threshold, the self-test is indicated as failed. This corresponds to the AtoBD self-test option in the figure.

[0066] For example, if the channel amplitude quantization signal output by channel B is less than or equal to the second threshold, it indicates that there is a problem in the signal transmission path between the upper plate corresponding to channel B and the beam position monitoring system.

[0067] 2. Use the relay to input the self-test signal directly from the B port to the upper plate of the beam position detector, and then input the sensing signals of the adjacent left and right plates into channel A (such as the left plate corresponds to channel A) and channel C (such as the right plate corresponds to channel C) through the corresponding front-end analog amplifier, analog-to-digital converter, and main control module in turn. Determine whether the channel amplitude quantization signals VA and VC output by channel A and channel C are greater than the second threshold, and the user interface directly displays the self-test results. That is, when both are greater than the preset second threshold, the self-test is displayed as passed, indicating that the coupling degree between the upper plate and the left and right plates, as well as the signal transmission path formed between the upper plate and the beam position monitoring system are appropriate. When at least one is less than or equal to the second threshold, the self-test is displayed as failed. Corresponding Figure 2 BtoAC self-test option.

[0068] 3. Through the relay, the self-test signal is input directly from the C port to the right plate of the beam position detector, and then the sensing signals of the adjacent upper plate and lower plate are input to channel B and channel D after passing through the corresponding front-end analog amplifier, analog-to-digital converter, and main control module. It is judged whether the channel amplitude quantization signals VB and VD output by channel B and channel D are greater than the second threshold value, and the user interface directly displays the self-test result. That is, when both are greater than the preset second threshold value, the self-test is displayed as passed, indicating that the coupling degree between the right plate and the upper plate and the lower plate, as well as the signal transmission path formed between the right plate and the beam position monitoring system are appropriate. When at least one is less than or equal to the second threshold value, the self-test is displayed as failed. Corresponding Figure 2 CtoBD self-test option.

[0069] 4. Through the relay, the self-test signal is input directly from the D port to the lower plate of the beam position detector, and then the sensing signals of the adjacent left plate and right plate are input to channel A and channel C in turn through the corresponding front-end analog amplifier, analog-to-digital converter, and main control module. It is judged whether the channel amplitude quantization signals VA and VC output by channel A and channel C are greater than the second threshold, and the user interface directly displays the self-test results. That is, when it exceeds the preset second threshold, it is displayed that the self-test has passed, indicating that the coupling degree between the lower plate and the left plate and the right plate, as well as the signal transmission path formed between the lower plate and the beam position monitoring system are appropriate. When at least one is less than or equal to the second threshold, it is displayed that the self-test has failed. The corresponding Figure 2 DtoAC self-test option in the middle.

[0070] 5. If all 1-4 above show that the self-test has passed, the interlock protection function will be activated at the same time as the self-test has passed is displayed on the user interface; if some items fail, it is necessary to conduct targeted inspections and then self-test again until they pass.

[0071] For example, see Figure 3 , Figure 3 Schematic diagram of signal transmission of a beam position detector plate in a self-test working mode according to an embodiment of the present invention.

[0072] Specifically, the signal source in the figure ( Figure 3 The upper left corner of the image (shown in the figure) can be used to provide a reference signal or self-test signal required for self-test. During the self-test process, the self-test signal can be directly input into the beam position monitoring system through a self-test port (such as the calibration port shown in the figure). This signal is used to test the signal transmission path formed between the analog-to-digital converter and the various plates of the beam position detector and the beam position monitoring system. KT1-1 and KT1-2 represent the relays connected to the left plate A, respectively. KT2-1 and KT2-2 represent the relays connected to the top plate B, respectively. KT3-1 and KT3-2 represent the relays connected to the right plate C, respectively. KT4-1 and KT4-2 represent the relays connected to the bottom plate D, respectively.

[0073] To automatically detect again, refer to the following steps:

[0074] Step 1: input the self-test signal again to the plate corresponding to the beam position detector where the signal transmission path has an abnormality;

[0075] Step 2: reacquiring the sensing signal generated by the plate adjacent to the plate that inputs the self-test signal again;

[0076] Step 3: Input the re-acquired sensing signal into the corresponding analog-to-digital converter and transmit it to the main control module;

[0077] Step 4: Obtain the channel amplitude quantization signal corresponding to each channel of the re-acquired sensing signal output by the main control module;

[0078] Step 5: Check whether the channel amplitude quantization signal corresponding to each newly acquired sensing signal is greater than a preset second threshold;

[0079] Step 6: If the channel amplitude quantization signals corresponding to all the reacquired sensing signals are greater than the second threshold, it is determined that the signal transmission path formed between the plate with the abnormality in the signal transmission path and the beam position monitoring system is working normally;

[0080] Step 7: If the channel amplitude quantization signal corresponding to at least one of the reacquired sensing signals is still less than or equal to the second threshold, repeat the above steps 1 to 5 until the signal transmission path formed between the plate of the beam position detector with the abnormal signal transmission path and the beam position monitoring system operates normally.

[0081] Specifically, for the plate whose signal transmission path was previously detected as abnormal during self-test, a self-test signal is re-input. This is to verify whether the problem still exists or whether the self-test can be completed by re-inputting the signal after the detector is reinstalled and the connection cables are checked. When the self-test signal is re-inputted to the plate with the abnormal signal transmission path, the sensing signals generated by the plates adjacent to the plate to which the self-test signal was input are acquired. These sensing signals reflect the response of the beam position detector to the self-test signal. The re-acquired sensing signals are input to the corresponding analog-to-digital converter, which converts the analog signals into digital signals. The analog-to-digital converter transmits the digital signals to the system's main control module. The main control module receives the digital signals from the analog-to-digital converter and outputs channel amplitude quantization signals corresponding to each re-acquired sensing signal. The channel amplitude quantization signals corresponding to each re-acquired sensing signal are checked to determine whether they are greater than a preset second threshold. This determines whether the signal transmission path between the plate with the abnormal signal transmission path and the beam position monitoring system is functioning properly. If the channel amplitude quantization signals corresponding to all the reacquired sensing signals are greater than the second threshold, then it can be considered that the signal transmission path formed between the plate with the abnormal signal transmission path and the beam position monitoring system is working normally. This means that the previous abnormality may be only temporary or has been resolved in some way. If the channel amplitude quantization signal corresponding to at least one of the reacquired sensing signals is still less than or equal to the second threshold, then it indicates that the problem still exists. In this case, self-test is required again until all channel amplitude quantization signals are greater than the second threshold, thereby confirming that the signal transmission path formed between the four plates of the beam position detector and the beam position monitoring system is in normal working condition, and then the beam position monitoring system can work online.

[0082] In summary, according to the technical solution provided in the embodiment of the present invention, effective troubleshooting and recovery operations can be performed when an abnormality occurs in the beam position detector. Through continuous testing and inspection, it can be ensured that the signal transmission path formed between the various plates of the beam position detector and the beam position monitoring system will not continue to be used before it is not working normally, thereby ensuring the safety and reliability of the system.

[0083] Furthermore, after the self-test signal is converted by the analog-to-digital converter, the value thereof is within the range of 10,000-25,000.

[0084] Specifically, after the self-test signal is converted by the analog-to-digital converter, its value is between 10,000 and 25,000. This range ensures that it is within the linear operating range of the analog-to-digital converter, ensuring the accuracy and reliability of the signal during the self-test process. The values between 10,000 and 25,000 represent the analog-to-digital conversion values of the analog-to-digital converter.

[0085] Furthermore, inputting a self-test signal to a multi-channel analog-to-digital converter of the beam position monitoring system includes:

[0086] The attenuator of the front-end analog amplifier of the beam position monitoring system connected to each analog-to-digital converter is adjusted to the maximum gear, and a self-test signal is input to the multi-channel analog-to-digital converter of the beam position monitoring system.

[0087] Specifically, the attenuator of the front-end analog amplifier is set to the maximum gear to prevent the analog-to-digital converter from operating in a saturated state and burning out components. At the same time, the self-test signal is input to the analog-to-digital converter through the front-end analog amplifier.

[0088] Furthermore, the self-test signal is sequentially inputted into the left plate, the upper plate, the right plate and the lower plate arranged circumferentially on the beam position detector, including:

[0089] The attenuator of the front-end analog amplifier of the beam position monitoring system connected to each analog-to-digital converter is adjusted to the through state, and the self-test signal is input into the left plate, upper plate, right plate and lower plate arranged in circumferential order on the beam position detector in sequence.

[0090] Specifically, because the coupling between the beam position detector plates is very small, the front-end analog amplifier is set to a direct pass state without attenuation. The self-test signal is then sequentially input to the left, upper, right, and lower plates arranged circumferentially on the beam position detector.

[0091] Further, after the beam position monitoring system is powered on, a self-test signal is obtained; and / or,

[0092] When receiving an execution instruction input by the user, a self-test signal is obtained.

[0093] Specifically, after receiving an execution instruction input by the user (ie, the user starts the self-test in the user interface) or the beam position monitoring system is powered on, the self-test signal is obtained.

[0094] When restarting the self-test, it can be performed according to the execution instructions input by the user.

[0095] In summary, the self-test method of the beam position monitoring system can be used in the power-on fully automatic self-test mode, the online real-time fully automatic self-test mode, and the online sub-item self-test mode. The power-on fully automatic self-test mode is to perform a fully automatic test on the signal transmission path formed between the analog-to-digital converter, each plate of the beam position detector, and the beam position monitoring system after the beam position monitoring system is powered on and the embedded system of the beam position monitoring is started, and a pass or fail result is given; the online real-time fully automatic self-test mode is to perform a fully automatic test on the signal transmission path formed between the analog-to-digital converter, each plate of the beam position detector, and the beam position monitoring system when the equipment is online but has not yet received the actual beam, and a self-test result is given; the online sub-item self-test mode mainly performs automatic inspections on different sub-items online, such as the analog-to-digital converter.

[0096] For example, during a self-test, a self-test signal is connected through the self-test port. Simultaneously, the sensing signals from the four electrodes of the beam position detector are amplified or attenuated by a front-end simulator, converted to digital signals by an analog-to-digital converter, and finally transmitted to the main control module. The main control module then filters, down-converts, and normalizes the digital signals to obtain a channel amplitude quantization signal. The channel amplitude quantization signal can be obtained using any technique known to those skilled in the art, and the present invention is not limited thereto.

[0097] Compared with the traditional self-test platform and method of beam position monitoring system, the present invention has the following characteristics and advantages:

[0098] The present invention provides a self-test method for a beam position monitoring system, which can realize self-test of the system to be tested without the need for manual self-test of all channels using equipment such as a vector network analyzer, or the use of complex signal processing algorithms. High-precision automatic detection can be achieved by only using waveform data of the beam position.

[0099] In the power-on fully automatic self-test mode, the system automatically executes steps 1-5 and provides the self-test results after power-on. In the online real-time fully automatic self-test mode, the system automatically executes steps 1-5 and provides the self-test results when the user presses the execution button. In the online itemized self-test mode, the user can perform a targeted check of a function in a specific step of steps 1-5 based on pre-judgment.

[0100] For example, the preset first threshold and second threshold can be set in advance according to the size of the self-test signal. The parameters will be automatically downloaded when the system starts up, and can also be adjusted at any time according to the theoretical value of the designed isolation between the connected self-test signal and the connected beam position detector plate.

[0101] In summary, users only need to input the self-test signal into the beam position monitoring system, connect the cable between the beam position monitoring system and the beam position detector, enter the preset threshold value on the user interface, and initiate the self-test. The program will then automatically execute and display the self-test results on the user interface, without requiring any additional operation. This method automatically determines the test results of the beam position monitoring system and determines the system's operational integrity. This allows users to understand the operational health of system channels and reduces troubleshooting difficulties for maintenance personnel. It offers advantages such as simplicity, intelligence, and practicality.
