[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] With the advancement of science and technology, accelerators are also developing in the direction of high current and high power, with the total beam power reaching the megawatt (MW) level. The proton and heavy ion accelerators currently in operation and under construction in the world all contain a proton or heavy ion linear accelerator as the main accelerator or injector, because the linear accelerator has a more compact structure and higher acceleration efficiency; and the superconducting linear accelerator has a higher acceleration electric field gradient due to the integration of low-temperature superconducting technology, and the overall length of the linear accelerator is greatly reduced. In this context, the beam diagnostic system of high-current and high-power proton and heavy ion linear accelerators and their related system technologies highlight their important position.

[0026] The existing beam position monitoring system mainly includes a beam position detector, a connecting cable and a beam position monitoring system. The beam position monitoring system also includes 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 the position and phase of the beam. When the beam passes through the beam position detector, an induction signal will be generated on the plate of the beam position detector, and the induction signal is an analog signal. The beam position detector is usually composed of four plates. According to the size of the induction signal generated by the four plates with the size of the beam, the horizontal position and vertical position of the beam and the phase of the beam can be calculated. The connecting cable is used to transmit the analog signal generated by the beam position detector to the front-end analog amplifier through the connecting cable. The front-end analog amplifier is used to amplify or attenuate 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 from the connecting cable, and transmits the analog signal processed by the front-end analog amplifier to the analog-to-digital converter. The analog-to-digital converter is used to convert 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 signal converted by the analog-to-digital converter, performing data analysis and variable control, and outputting the final beam position measurement results. The main control module receives the digital signal from the analog-to-digital converter, outputs information such as beam position and phase after algorithm processing, and controls the operation of the entire monitoring system. Thus, the analysis and processing of the beam position and phase signals are realized, which is an important part of the accelerator beam monitoring system. Therefore, the health status of the entire signal transmission link between the beam position detector of the beam position monitoring system and the main control module and the reliability of the self-test results of the signal transmission path between each plate of the detector and the beam position monitoring system are particularly important for the beam position monitoring system. Among them, each plate of the beam position detector is connected to a front-end analog amplifier and an analog-to-digital converter in turn, and finally connected to the main control module. The induction signal generated by each plate is transmitted to the front-end amplifier through the connecting cable, then to the analog-to-digital converter, and finally to the main control module, forming a signal transmission path.

[0027] Figure 1 It is a flowchart of a self-checking method of a beam position monitoring system provided according to an embodiment of the present invention.

[0028] like Figure 1 As shown, the self-checking method of the beam position monitoring system provided in the embodiment of the present invention can be executed by the beam position monitoring system, and the method includes the following steps: Step 101: If the signal acquisition module of the beam position monitoring system receives self-test trigger information, a self-test signal is acquired.

[0029] In one embodiment of the present invention, a self-test signal is input from a self-test port of a beam position monitoring system, which is a manually set test signal used to simulate a beam signal under actual working conditions, i.e., a simulation signal, so as to facilitate checking the functions of various parts of the beam position monitoring system. The beam position monitoring system detects an internal or external self-test trigger information, which may be due to user operation, a predetermined self-test time, power-on of the beam position monitoring system, or an abnormality detected by the beam position monitoring system, and then starts to receive a self-test signal from the self-test port.

[0030] Step 102 , input the self-test signal to the analog-to-digital converter of the beam position monitoring system to determine whether the analog-to-digital converter works normally.

[0031] In one embodiment of the present invention, after receiving the self-test signal, the beam position monitoring system will send the self-test signal to 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 checks whether the digital signal output by the analog-to-digital converter meets expectations, thereby determining whether the analog-to-digital converter is working normally.

[0032] Step 103, when the analog-to-digital converter is operating normally, input the self-test signal to each electrode plate of the beam position detector of the beam position monitoring system to determine whether the signal transmission path formed between each electrode plate of the beam position detector and the beam position monitoring system of the beam position monitoring system is operating normally.

[0033] In one embodiment of the present invention, a plurality of 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 plate of the beam position detector to which the self-test signal is input 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.

[0034] 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 working normally; 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.

[0035] In one embodiment of the present invention, the beam position monitoring system includes a plurality of front-end analog amplifiers, a multi-channel analog-to-digital converter and a main control module, each plate is sequentially connected to a front-end analog amplifier, a channel analog-to-digital converter, and finally connected to the main control module to form a signal transmission path. After the self-test signal is input into each plate of the beam position detector, the induction signal generated by the adjacent plate of each plate is detected, and it is determined that the signal transmission path between each plate of the beam position detector and the beam position monitoring system is working normally, the self-test process is completed, and the self-test result is output.

[0036] Exemplarily, the user may be notified of the self-check result through user interface display, log recording, or other means.

[0037] In summary, according to the technical solution provided in 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-checked in turn to determine whether it is working normally, and finally the self-test result is output, which 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.

[0038] Furthermore, the self-test signal is input into an analog-to-digital converter of a beam position monitoring system to determine whether the analog-to-digital converter is working properly, including: inputting a self-test signal to a multi-channel analog-to-digital converter of a beam position monitoring system; 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; If all channel amplitude quantization signals are greater than the first threshold, each analog-to-digital converter is judged to be 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, the analog-to-digital converter of the beam position monitoring system is judged to be working abnormally.

[0039] Specifically, the beam position monitoring system has multiple analog-to-digital converters, and the self-test signal is sent to each analog-to-digital converter in the beam position monitoring system. These analog-to-digital converters are responsible for converting analog signals into digital signals for further processing. After processing the self-test signal, each analog-to-digital converter will output a corresponding digital signal. These digital signals are then transmitted to the main control module of the beam position monitoring system, which is responsible for receiving and processing signals from all analog-to-digital converters and outputting channel amplitude quantization signals corresponding to each analog-to-digital converter. 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. The first threshold can be determined by considering system performance, historical data or self-test signals, or by the professional knowledge and experience of technicians. If the channel amplitude quantization signals output by all analog-to-digital converters are greater than the first threshold, then it can be determined that all analog-to-digital converters are working normally because they can correctly convert the self-test signal and ensure accuracy. If the channel amplitude quantization signal output by at least one analog-to-digital converter is less than or equal to the first threshold, then the system will determine that at least one analog-to-digital converter is working abnormally. This may mean that the ADC cannot convert the signal correctly or there is another fault. If the ADC is detected to be working abnormally, the system may trigger an alarm, record the error information, and take further diagnostic measures, such as recalibration, replacement of the faulty ADC, or other necessary maintenance operations. Among them, the channel amplitude quantization signal is obtained by the main control module after filtering, down-converting, and normalizing the digital signal.

[0040] 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 a 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 at least one channel amplitude quantization signal is 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 recalibrating, replacing the faulty analog-to-digital converter, or performing other necessary maintenance operations. Figure 2 As shown, Figure 2Schematic diagram of the beam position monitoring system provided by an embodiment of the present invention. The analog-to-digital converter is self-checked, i.e., ADC Check, and the channel amplitude quantization signals corresponding to the corresponding multi-channel analog-to-digital converters are output by channels A, B, C, and D, and the channel amplitude quantization signal output by each channel is compared with the first threshold value (i.e., Threshold1).

[0041] Figure 2 In the example, Att.=-30dB means that the signal is amplified by 30dB. In signal processing, a negative attenuation value usually means that the signal is amplified rather than attenuated. Here, "-30dB" means that the signal strength is increased by 30 decibels.

[0042] 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.

[0043] Exemplarily, the beam position monitoring system has four signal transmission paths, and the corresponding channel amplitude quantization signals also have four.

[0044] In summary, according to the technical solution provided by the embodiment of the present invention, the beam position monitoring system can automatically detect and verify the working status of each analog-to-digital converter, ensuring that the entire system can provide accurate measurement results in actual operation. This self-checking mechanism is crucial to maintaining the reliability and stability of the system.

[0045] Furthermore, when the analog-to-digital converter works normally, the self-test signal is input to each electrode plate of the beam position detector of the beam position monitoring system to judge whether the signal transmission path formed between each electrode plate of the beam position detector and the beam position monitoring system of the beam position monitoring system works normally, including: When the analog-to-digital converter works normally, the self-test signal is sequentially inputted into the left plate, the upper plate, the right plate and the lower plate which are sequentially arranged on the beam position detector in the circumferential direction; Acquire the induction signals generated by other plates adjacent to the plate to which the self-test signal is input; input the induction signals into the corresponding analog-to-digital converters, and transmit them to the main control module of the beam position monitoring system; The main control module outputs a channel amplitude quantization signal corresponding to each sensing signal; Check whether the channel amplitude quantization signal corresponding to each sensing signal is greater than a preset second threshold; If the channel amplitude quantization signals corresponding to all the 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.

[0046] Specifically, the beam position detector is sequentially provided with a left plate, an upper plate, a right plate and a lower plate in the circumferential direction. When the analog-to-digital converter is working normally, the self-test signal is sequentially input into the four plates (i.e., the left plate, the upper plate, the right plate and the lower plate) of the beam position detector. When the self-test signal is input into a certain plate, due to physical effects (such as electromagnetic induction), the adjacent plates will generate an induction signal. The induction signal is an analog signal, and the generated induction signal is transmitted to the corresponding analog-to-digital converter, converted into a digital signal by the analog-to-digital converter, and the converted signal is transmitted to the main control module by the analog-to-digital converter. Thus, the main control module receives the digital signal from the multi-channel analog-to-digital converter and outputs the channel amplitude quantization signal corresponding to each induction signal. The channel amplitude quantization signal of each channel is compared with a preset second threshold. The preset second threshold can be determined by considering the system performance, historical data or self-test signal, or by the professional knowledge and experience of the technician. If all channel amplitude quantization signals are greater than the second threshold, it is considered that the signal transmission path formed between each detector plate and the beam position monitoring system is working properly, because all channel amplitude quantization signals can reach a certain intensity. If any channel amplitude quantization signal is less than or equal to the second threshold, it is considered that there is a problem in the signal transmission path formed between the plate of the beam position detector and the beam position monitoring system involving the channel amplitude quantization signal, and further inspection and maintenance are required.

[0047] 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 the contact of the signal connection cable is good. For details, please refer to the following methods: 1. Through the relay, the self-test signal is directly input from the A port to the left plate of the beam position detector, and then the sensing signals of the adjacent upper plate and lower plate are respectively input to the corresponding channel B (such as the upper plate corresponds to channel B) and channel D (such as the lower plate corresponds to channel D) 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 (ie, Threshold2), 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 left plate and the upper plate and the lower plate, and the signal transmission path formed between the left 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. The corresponding AtoBD self-test option in the figure.

[0048] Exemplarily, 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 formed between the upper board corresponding to channel B and the beam position monitoring system.

[0049] 2. Use the relay to input the self-test signal directly from port B 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.

[0050] 3. Use the relay to input the self-test signal directly from the C port to the right plate of the beam position detector, and then input the sensing signals of the adjacent upper plate and lower plate to channel B and channel D through the corresponding front-end analog amplifier, analog-to-digital converter, and main control module in turn. Determine whether the channel amplitude quantization signals VB and VD output by channel B and channel D 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 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, the self-test is displayed as failed. Corresponding Figure 2 CtoBD self-test option.

[0051] 4. Use the relay to input the self-test signal directly from the D port to the lower plate of the beam position detector, and then input the sensing signals of the adjacent left and right plates into channels A and 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 channels A and 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, the self-test is displayed as passed, indicating that the coupling degree between the lower plate and the left and right plates, 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, the self-test is displayed as failed. Corresponding Figure 2 DtoAC self-test option in.

[0052] 5. If the above 1-4 all show that the self-test has passed, the interlock protection function will be activated when the user interface shows that the self-test has passed; if some items have not passed, it is necessary to conduct targeted inspections and then self-test again until they pass.

[0053] For example, see Figure 3 , Figure 3 It is a schematic diagram of signal transmission of the plate of the beam position detector provided in the self-test working mode according to the embodiment of the present invention.

[0054] Specifically, the signal source in the figure ( Figure 3 The upper left corner) 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 the self-test port (such as the calibration port shown in the figure), which is used to detect the signal transmission path formed between the analog-to-digital converter and each plate of the beam position detector and the beam position monitoring system. KT1-1 and KT1-2 represent the relays connected on both sides of the left plate A. KT2-1 and KT2-2 represent the relays connected on both sides of the upper plate B. KT3-1 and KT3-2 represent the relays connected on both sides of the right plate C. KT4-1 and KT4-2 represent the relays connected on both sides of the lower plate D.

[0055] To automatically detect again, please refer to the following steps: 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; Step 2: reacquire the induction signal generated by the plate adjacent to the plate that inputs the self-test signal again; Step 3: Input the reacquired sensing signal into the corresponding analog-to-digital converter and transmit it to the main control module; Step 4: Obtain the channel amplitude quantization signal output by the main control module corresponding to each channel of the re-acquired sensing signal; Step 5: Check whether the channel amplitude quantization signal corresponding to each re-acquired sensing signal is greater than a preset second threshold; Step 6: If the channel amplitude quantization signals corresponding to all the re-acquired sensing signals are greater than the second threshold, it is determined that the signal transmission path formed between the plate with abnormal beam signal transmission path and the beam position monitoring system is working normally; 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.

[0056] Specifically, for the plate whose signal transmission path is found to be abnormal in the previous self-test, the 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 cable is checked. When the self-test signal is input to the plate with abnormal signal transmission path again, the sensing signal generated by the plate adjacent to the plate where the self-test signal is input is obtained. These sensing signals reflect the response of the beam position detector to the self-test signal. The re-acquired sensing signal is input to the corresponding analog-to-digital converter, and the analog-to-digital converter converts the analog signal into a digital signal, and the analog-to-digital converter transmits the digital signal to the main control module of the system. The main control module receives the digital signal from the analog-to-digital converter and outputs the channel amplitude quantization signal corresponding to each re-acquired sensing signal. The channel amplitude quantization signal corresponding to each re-acquired sensing signal is checked to determine whether they are greater than the preset second threshold. In order to determine whether the signal transmission path formed between the plate with abnormal signal transmission path and the beam position monitoring system is working normally. 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 at least one channel amplitude quantization signal corresponding to the reacquired sensing signal is still less than or equal to the second threshold, it indicates that the problem still exists. In this case, self-checking 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 the beam position monitoring system can work online.

[0057] 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 fails to work normally, thereby ensuring the safety and reliability of the system.

[0058] Furthermore, after the self-test signal is converted by the analog-to-digital converter, the value of the signal is within the range of 10000-25000.

[0059] Specifically, after the self-test signal is converted by the analog-to-digital converter, the value is within 10000-25000, because this range ensures that it is within the linear working range of the analog-to-digital converter and can ensure the accuracy and reliability of the signal during the self-test process. Among them, between 10000 and 25000 is the analog-to-digital conversion value of the analog-to-digital converter.

[0060] Further, inputting a self-test signal to a multi-channel analog-to-digital converter of the beam position monitoring system includes: 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 converters of the beam position monitoring system.

[0061] Specifically, the attenuator of the front-end analog amplifier is set to the maximum gear to prevent the analog-to-digital converter from burning out components when operating in a saturated state. At the same time, the self-test signal is input to the analog-to-digital converter through the front-end analog amplifier.

[0062] Further, the self-test signal is sequentially inputted into the left plate, the upper plate, the right plate and the lower plate sequentially arranged in the circumferential direction on the beam position detector, including: The attenuator of the front-end analog amplifier of the beam position monitoring system connected to each analog-to-digital converter is adjusted to a 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.

[0063] Specifically, since the coupling degree between the beam position detector plates is very small, the front-end analog amplifier is directly set to a through state without attenuation. The self-test signal is then sequentially input to the left plate, upper plate, right plate and lower plate arranged circumferentially on the beam position detector.

[0064] Further, after the beam position monitoring system is powered on, the self-test signal is obtained; and / or, When receiving an execution instruction input by the user, a self-test signal is obtained.

[0065] Specifically, after receiving an execution instruction input by a user (ie, the user starts a self-test in the user interface) or the beam position monitoring system is powered on, the self-test signal is started to be obtained.

[0066] When restarting the self-test, it can be performed according to the execution instructions input by the user.

[0067] 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 electrode 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 electrode of the beam position detector and the beam position monitoring system when the equipment is running 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 checking the analog-to-digital converter, etc.

[0068] Exemplarily, when performing a self-test, a self-test signal is connected through the self-test port, and at the same time, the induction signals of the four plates of the beam position detector are amplified or attenuated by the front-end simulator, and then converted into digital signals by the analog-to-digital converter, and finally transmitted to the main control module, and then the main control module filters, down-converts, and normalizes the digital signals to obtain a channel amplitude quantization signal. The channel amplitude quantization signal can be obtained by any technology known to those skilled in the art, and the present invention is not limited here.

[0069] Compared with the traditional self-checking platform and method of beam position monitoring system, the present invention has the following characteristics and advantages: A self-check method for a beam position monitoring system provided by the present invention can realize self-check work on the system to be tested. There is no need to use equipment such as a vector network analyzer to perform manual self-check on all channels, and there is no need to use complex signal processing algorithms. High-precision automatic detection can be achieved by only using waveform data of the beam position.

[0070] The power-on fully automatic self-test mode is that after power-on, the system automatically executes the above steps 1-5 and gives the self-test results after startup; the online real-time fully automatic self-test mode is that when the user needs it, the execution button is pressed to automatically execute the above steps 1-5 and give the self-test results; the online sub-item self-test mode is that the user performs a targeted check of a certain function in a certain step of the above steps 1-5 based on prejudgment.

[0071] Exemplarily, the preset first threshold and second threshold can be set in advance according to the size of the self-test signal. The parameter will be automatically downloaded when the system starts, 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.

[0072] In summary, the user only needs to input and output the self-test signal to the beam position monitoring system, connect the connecting cable between the beam position monitoring system and the beam position detector, input the preset threshold value on the user interface to start the self-test, and the program will be automatically executed. Finally, the self-test result will be displayed on the user interface without excessive operation. It can automatically determine the test results of the beam position monitoring system, obtain the system working integrity status, and master the working health status of the system channel, reducing the difficulty of troubleshooting for maintenance personnel. It has the advantages of simple method, intelligence, and strong practicality.
