[0002] With the development of computer technology, technologies have emerged that use computer-outputted analog signals to test various systems. For example, in the field of nuclear power technology, data processing and analysis systems are tested by transmitting electrical signals through computers.

[0003] Currently, in the process of testing a system via computer, the reactor system under test is typically connected directly to a virtual interface on the computer. However, transmitting test signals to the system under test through the computer's virtual interface presents several problems. First, inconsistent data processing paths can occur. Second, the test signals output by the computer represent ideal values ​​and do not reflect the data obtained under actual conditions. Therefore, transmitting test signals to the system under test through a computer's virtual interface leads to inaccurate test results, a problem that urgently needs to be addressed.

[0062] In the aforementioned system testing methods, devices, equipment, and storage media for nuclear power plant reactors, the data transmitting end, after acquiring the original sample data for testing the system under test, does not directly send the original sample data to the system under test. Instead, it first corrects the original sample data according to a pre-determined signal transmission deviation, obtaining corrected sample data, which is then transmitted to the signal source. The signal source then converts the corrected sample data into a detection signal and sends it to the system under test. In this scheme, the computer's data transmitting end does not directly send detection signals to the system under test through a virtual interface. Instead, it introduces a signal source, i.e., sends detection signals to the system under test based on actual physical equipment. Compared to sending signals through a virtual interface, this method offers higher stability and solves the problem of inconsistent data processing paths that exist when transmitting detection signals through a virtual interface. It ensures the uniformity of the data processing path and further guarantees the accuracy of the signals received by the system under test. In addition, the sample data sent from the data transmitter to the signal source is the corrected sample data after deviation correction, which makes the corrected data received by the signal source more in line with the requirements (i.e., closer to the original sample data). This reduces the signal deviation when the signal source transmits the detection signal to the system under test from multiple dimensions, thereby making the detection results of the system under test more accurate.

[0082] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0083] Before introducing the embodiments of this application, it should be noted that the detection system of this application can be taken as an example of a data analysis system for detecting neutron flux in a nuclear power reactor. In nuclear power plants, neutron flux measurement plays a crucial role in the operational status of the nuclear reactor. Currently, nuclear power plants mostly measure neutron flux by using high-precision, high-performance neutron flux detectors within the reactor. The neutron flux is then converted into a continuous micro-current or micro-voltage signal, and the data analysis system performs various data processing and analysis based on these micro-current or micro-voltage signals. However, nuclear power plant data analysis systems are used periodically, only going online during specific reactor phases. Normally, these systems are stored in an instrument and equipment warehouse and are not connected to the reactor's real-time signals. Therefore, to avoid inaccurate neutron energy measurements due to system malfunction, the data analysis system needs to undergo system testing of the nuclear power plant reactor before each use to ensure its proper functioning.

[0084] The system detection method for nuclear power plant reactors provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the data transmitter 102 communicates with the signal source 104 via a network. The data storage system can store the data that the data transmitter 102 needs to process, such as raw sample data. The data storage system can be integrated into the data transmitter 102 or placed in the cloud or on another network server. Specifically, the data transmitter 102 corrects the acquired raw sample data for testing the system under test, obtaining corrected sample data, and sends the corrected sample data to the signal source 104. The signal source 104 performs signal conversion processing on the received corrected sample data to obtain a detection signal, and sends the detection signal to the system under test. The data transmitter 102 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0085] In one embodiment, such as Figure 2 As shown, a system detection method for a nuclear power plant reactor is provided, which is applied to... Figure 1 Taking the data sending end 102 as an example, the explanation includes the following steps:

[0086] S201, Obtain the raw sample data for testing the system to be tested.

[0087] The system to be tested is a nuclear power plant reactor system. In this embodiment, the system to be tested is a data analysis system for neutron flux detection in the nuclear power field, which is used as an example. The original sample data can be electrical signal data used when testing the system to be tested; it can be a set of data or a single data point. For example, if the system to be tested is a data analysis system for neutron flux detection, the original sample data can be multiple sets of different test voltage values ​​and test current values.

[0088] In one embodiment, the raw sample data may include at least one of the following: electrical signal data of the system under test in its historical operating states, user-configured electrical signal data, and system simulation electrical signal data. The electrical signal data may include current signal data, voltage signal data, or both current and voltage signal data; there is no limitation in this regard. The electrical signal data of the system under test in its historical operating states may be real electrical signal data previously processed by the system under test. For example, it may be real signal data from different stages and states of a nuclear reactor. Exemplarily, it may include real signal data from the reactor's first criticality, real signal data from nuclear heating point measurement experiments, real signal data from detector overlap measurements, real signal data from reactivity verification, real signal data from isothermal temperature coefficient analysis, real signal data from end-point boron concentration measurement experiments, and real signal data from rod value measurements (including dilution method, alternation method, borylation method, rod engraving method, dynamic rod engraving method, subcritical rod engraving method, etc.). The user-configured electrical signal data may be electrical signal data prepared in advance by system testing personnel for testing the system under test. For example, it may be pre-prepared data stored in a file for system testing of the nuclear power plant reactor. The electrical signal data simulated in the system can be automatically generated by the data transmitter. For example, it can be electrical signal data generated by simulation software according to user settings, conforming to a certain pattern. For instance, it could be a multiplicative periodic current signal simulated based on parameters set by the data transmitter, or a voltage signal generated based on the position of the control rod. It should be noted that since the control rods correspond to different voltage values ​​from the top to the bottom of the reactor core, the voltage signal generated at different locations within the core will gradually change (e.g., gradually decrease) as the control rod is inserted from the top. In this embodiment, the voltage signals generated at different locations within the reactor core can be statistically analyzed, and each voltage signal corresponds to a control rod position, i.e., a reactor state. For example, a "rod position-voltage lookup table" can be generated based on the position of each control rod and its corresponding voltage signal. The user can then find the corresponding voltage signal based on the desired control rod position to obtain the original sample data.

[0089] In the above embodiments, using multiple types of raw signal data to detect the system under test makes the data sources for detecting the system under test richer and more comprehensive, thus ensuring the accuracy of the detection results.

[0090] Optionally, the method for obtaining raw sample data for testing the system under test can be to determine the corresponding raw sample data based on the type of raw data sample. It should be noted that the data sending end can determine the raw sample data through a raw sample database containing data for system testing of the system under test. This database pre-stores real signal data of the system under test during operation. When there is a need to test the system under test, the data sending end can automatically obtain real electrical signal data that matches the current testing requirements from the raw sample database and use this real signal data as the raw sample data. When the raw sample data is user-configured electrical signal data, the system testing personnel can upload or input the pre-prepared raw sample data required for testing the system under test to the data sending end. The data sending end receives the uploaded or input data and uses it as the raw sample data for testing the system under test. When the raw sample data is electrical signal data simulated by the system, the method for obtaining the raw sample data for testing the system under test can be that the data sending end, based on the current testing requirements and pre-set signal data generation parameters, calls the simulation module to simulate and generate electrical signal values. The data sending end then uses the generated electrical signal values ​​as the raw sample data.

[0091] It should be noted that the original sample database can be updated and expanded based on actual online measurement data.

[0092] S202, determine the signal transmission deviation corresponding to the original sample data, and correct the original sample data according to the signal transmission deviation to obtain corrected sample data.

[0093] Signal transmission deviation can be caused by deviations in the signal source's signal conversion processing of the corrected sample data, or by deviations in the transmission of the detection signal. Corrected sample data can be more accurate sample data obtained by processing the original sample data. It is understandable that there may be some deviations in the signal conversion processing of the corrected sample data at the signal source. Additionally, there will be some transmission deviations when the signal source sends the detection signal to the system under test. Therefore, the deviations incurred during signal conversion processing and the transmission deviations are considered together as the signal transmission deviation.

[0094] Optionally, determining the signal transmission deviation corresponding to the original sample data can be done by determining the signal transmission deviation corresponding to the data transmitter based on the data sent by the data transmitter and the data received by the signal source, according to a predetermined transmission deviation determination strategy. Alternatively, it can be done by determining the target signal transmission interface corresponding to the original sample data from the external signal transmission interfaces of the signal source; wherein the external signal transmission interfaces include current transmission interfaces and voltage transmission interfaces for sending detection signals to the system under test; the signal transmission deviation corresponding to the original sample data is determined based on the signal transmission deviation corresponding to the target signal transmission interface. It is understood that the external signal transmission interface of the signal source can be the channel interface through which the signal source sends signals to the system under test. In this embodiment, each external transmission interface of the signal source corresponds to a set of original sample data, and the signal source can send signals through multiple external transmission interfaces when sending signals to the system under test. Accordingly, each external signal transmission interface of the signal source will have its corresponding signal transmission deviation when sending its corresponding original sample data; the signal transmission deviations of different external signal transmission interfaces can be different or the same. Therefore, in this embodiment, the signal transmission deviation corresponding to the original sample data can be determined based on the predetermined signal transmission deviations corresponding to each external signal transmission interface.

[0095] Furthermore, the original sample data can be corrected by processing it according to a predetermined signal transmission deviation to neutralize the deviation. For example, when the signal transmission deviation is positive, it means that the data received by the signal source is larger than the data sent by the data transmitter during signal transmission. In this case, the signal source can subtract the signal transmission deviation from the original sample data before sending it, ensuring that the data received by the signal source is the original sample data. Conversely, when the signal transmission deviation is negative, it means that the data received by the signal source is smaller than the data sent by the data transmitter during signal transmission. In this case, the signal source can add the signal transmission deviation to the original sample data before sending it. For example, if the original sample data is 10V and the predetermined signal transmission deviation is 0.2V, it means that when the data transmitter sends 10V data, the signal source will receive 10.2V data. In this case, the signal transmission deviation of 0.2V is subtracted from the original sample data of 10V to obtain the corrected sample data of 9.8V, thus ensuring that the data received by the signal source is 10V.

[0096] S203, the corrected sample data is transmitted to the signal source, so that the signal source converts the corrected sample data into a detection signal and sends it to the system under test for system detection.

[0097] Optionally, the data transmitter can use one transmission interface to transmit the corrected sample data to the signal source, or it can use multiple transmission interfaces to transmit each corrected sample data to the signal source; there is no limitation on this.

[0098] Specifically, in this embodiment, after the data sending end transmits the corrected sample data to the signal source end, the signal source end can process the corrected sample data, convert it into a detection signal, and send the detection signal to the system under test, enabling the system under test to perform system detection based on the detection signal. The processing procedure of the corrected sample data by the signal source end will be described in detail in subsequent embodiments and will not be elaborated here.

[0099] In the aforementioned system testing method for nuclear power plant reactors, after acquiring the original sample data of the system under test, the data transmitting end does not directly send the original sample data to the system under test. Instead, it first corrects the original sample data according to a pre-determined signal transmission deviation, obtaining corrected sample data, which is then transmitted to the signal source. The signal source then converts the corrected sample data into a detection signal and sends it to the system under test. In this scheme, the computer's data transmitting end does not directly send the detection signal to the system under test through a virtual interface. Instead, it introduces a signal source, that is, it sends the detection signal to the system under test based on the actual physical equipment. Compared with sending signals through a virtual interface, this method offers higher stability and solves the problem of inconsistent data processing paths that exist when transmitting detection signals through a virtual interface. It ensures the uniformity of the data processing path and further guarantees the accuracy of the signals received by the system under test. In addition, the sample data sent from the data transmitter to the signal source is the corrected sample data after deviation correction, which makes the corrected data received by the signal source more in line with the requirements (i.e., closer to the original sample data). This reduces the signal deviation when the signal source transmits the detection signal to the system under test from multiple dimensions, thereby making the detection results of the system under test more accurate.

[0100] Furthermore, before testing the system to be tested, it is necessary to determine the signal transmission deviation corresponding to the external signal transmission interface of the signal source. In one embodiment, the signal transmission deviation corresponding to the external signal transmission interface of the signal source can be determined by performing transmission accuracy verification on the data sending end and the signal source end. Specifically, for example... Figure 3 As shown, it may include the following steps:

[0101] S301 sends the verification sample data to the signal source end, so that the signal source end can convert the verification sample data into a verification signal and output it through the external signal transmission interface.

[0102] Among them, the verification sample data can be used to verify the transmission accuracy of the data sending end and the signal source end.

[0103] Optionally, the data transmitter may send the verification sample data to the signal source only once, allowing the signal source to perform signal conversion processing on the verification sample data to obtain a detection signal, which is then sent to all external signal transmission interfaces for output. Alternatively, the data transmitter may send multiple verification sample data sets, the same number as the number of external signal transmission interfaces at the signal source, with each verification sample data set corresponding to one external signal transmission interface. This allows the signal source to perform signal conversion processing on each verification sample data set to obtain a detection signal, which is then sent to the corresponding external signal transmission interface for output. It should be noted that when sending verification sample data, the data transmitter can specify one or more of the external signal transmission interfaces for transmission; this is not limited. The process of the signal source processing the verification sample data will be described in detail in subsequent embodiments.

[0104] S302, obtain the actual output signal value of the external signal transmission interface fed back from the signal source.

[0105] The actual output signal value is the signal value detected by the external signal transmission interface when the external signal transmission interface performs signal transmission operation based on the verification signal.

[0106] Specifically, during the process of the signal source outputting the detection signal through the external signal transmission interface, an electrical signal measuring instrument, such as a digital multimeter, can be used to measure the electrical signal output by the signal source. The reading of the electrical signal measuring instrument is regarded as the actual output signal value sent by the signal source through the external signal transmission interface, and the actual output signal value is fed back to the data sending end.

[0107] It should be noted that the signal source includes multiple external signal transmission interfaces. In this embodiment, the actual output signal value fed back by each external signal transmission interface can be obtained separately.

[0108] S303, based on the actual output signal value of the external signal transmission interface and the verification sample data, determine the signal transmission deviation corresponding to the external signal transmission interface.

[0109] Specifically, the actual output signal value corresponding to each external signal transmission interface fed back from the signal source is compared with the corresponding verification sample data of the external signal transmission interface. For example, difference processing is performed to determine the difference between the actual output signal value fed back from each external signal transmission interface of the signal source and the corresponding verification sample data. This difference is used as the signal transmission deviation corresponding to the external signal transmission interface.

[0110] In the above embodiments, before testing the system to be tested, the transmission accuracy of the data sending end and the signal source end is checked to determine the signal transmission deviation, which provides a basis for correcting the original sample data by using the signal transmission deviation when actually testing the system to be tested.

[0111] In another embodiment, a system detection method for a nuclear power plant reactor is also provided, which is applied to... Figure 1 Taking signal source terminal 104 as an example, the explanation is as follows: Figure 4 As shown, it includes the following steps:

[0112] S401, Obtain the corrected sample data transmitted by the data sender.

[0113] The corrected sample data is obtained by the data transmitter correcting the original sample data based on the signal transmission deviation corresponding to the original sample data. Specifically, the signal source can receive the corrected sample data transmitted by the data transmitter through the transmission interface between the signal source and the data transmitter. For example, the transmission interface between the signal source and the data transmitter can be a Thunderbolt interface.

[0114] It should be noted that the original sample data includes at least one of the following: electrical signal data of the system under test in its historical operating states, electrical signal data configured by the user, and electrical signal data from system simulation. The specific contents have been detailed in S201 above and will not be repeated here.

[0115] Optionally, in this embodiment, when the data sending end has a need to perform system testing on the system to be tested, it can obtain the original sample data and correct the original sample data according to the signal transmission deviation to obtain corrected sample data. The data sending end transmits the corrected sample data to the signal source end. At this time, the signal source end obtains the corrected sample data transmitted by the data sending end and performs the next operation.

[0116] S402, perform signal conversion processing on the corrected sample data to obtain the detection signal.

[0117] Specifically, the signal source can perform signal conversion processing on the received correction sample data, converting it into a detection signal. Optionally, the signal source can perform signal conversion processing by including a signal processor to convert the correction sample data into a detection signal. For example, there can be a voltage conversion processor and a current conversion processor. Based on the type of the received correction sample data (i.e., voltage signal data or current signal data), the processor performs signal conversion processing. When the correction sample data is voltage signal data, the voltage conversion processor performs voltage conversion processing, converting the voltage signal data into a voltage signal; when the correction sample data is current signal data, the current conversion processor performs current conversion processing, converting the current signal data into a current signal.

[0118] S403 sends the detection signal to the system under test so that the system under test can perform system detection based on the detection signal.

[0119] Specifically, the signal source will correct the detection signal corresponding to the sample data and send it to the system under test through the external signal transmission interface, so that the system under test can perform system detection based on the detection signal.

[0120] Optionally, before sending the detection signal to the system under test, the target signal transmission interface corresponding to the detection signal can be determined from the external signal transmission interfaces. If the detection signal is less than the signal transmission threshold of the corresponding target signal transmission interface, the detection signal is transmitted to the system under test through the target signal transmission interface. The signal transmission threshold can be pre-set and characterizes the signal range that the signal transmission interface can transmit. The correction sample data can be a set of sample data containing multiple data points, and each correction sample data point corresponds to one external signal transmission interface of the signal source. That is, one external signal transmission interface of the signal source can output a detection signal corresponding to one correction sample data point. Therefore, after processing the correction sample data, the signal source will obtain multiple detection signals, each of which needs to be output through its corresponding external signal transmission interface. In this embodiment, each external signal transmission interface corresponding to each detection signal is designated as a target signal transmission interface. The signal transmission threshold corresponding to the target signal transmission interface is compared with the magnitude of the detection signal corresponding to that interface to determine whether the detection signal is less than the threshold. If so, the detection signal is output to the system under test through the target signal transmission interface; otherwise, the output signal is abandoned. By setting the signal transmission threshold corresponding to the target transmission interface, the electrical signal value output through that interface is ensured not to be too large, thereby preventing damage to the system under test due to excessively large output electrical signals and further protecting the system under test.

[0121] In the above embodiments, after acquiring the original sample data for testing the system under test, the data sending end does not directly send the original sample data to the system under test. Instead, it first corrects the original sample data according to a pre-determined signal transmission deviation, obtaining corrected sample data. This corrected sample data is then transmitted to the signal source end, which converts the corrected sample data into a detection signal and sends it to the system under test. In this solution, the computer's data sending end does not directly send the detection signal to the system under test through a virtual interface. Instead, it introduces the signal source end, i.e., sending the detection signal to the system under test based on the actual physical device. Compared to sending signals through a virtual interface, this method offers higher stability, thus ensuring the accuracy of the signal received by the system under test. Furthermore, the sample data sent by the data sending end to the signal source end is corrected sample data after deviation correction. This makes the corrected data received by the signal source end more consistent with the requirements (i.e., closer to the original sample data), reducing the signal deviation when the signal source end transmits the detection signal to the system under test from multiple dimensions, thereby making the detection results for the system under test more accurate.

[0122] Furthermore, the determination of the signal transmission deviation corresponding to each of the above signal transmission interfaces is described in detail, such as... Figure 5 As shown, it may include the following steps:

[0123] S501, obtain the verification sample data sent by the data sender.

[0124] Specifically, the signal source receives the verification sample data transmitted by the data sender.

[0125] S502 performs signal conversion processing on the verification sample data to obtain the verification signal.

[0126] Specifically, the signal source performs signal conversion processing on the received verification sample data to convert the verification sample data into a verification signal. The process of performing signal conversion processing on the verification sample data to obtain the verification signal is the same as the process of performing signal conversion processing on the correction sample data to obtain the detection signal, and will not be described in detail here.

[0127] It should be noted that there is a corresponding verification sample for each external signal transmission interface.

[0128] S503 outputs a verification signal through the external signal transmission interface corresponding to the verification signal, and obtains the actual output signal value of the external signal transmission interface.

[0129] Specifically, when each verification signal is output through its corresponding external signal transmission interface, the electrical signal output by each external signal transmission interface can be measured using an electrical signal measuring instrument, such as a digital multimeter. The reading of the electrical signal measuring instrument is regarded as the actual output signal value sent out by that external signal transmission interface.

[0130] S504 feeds back the actual output signal value of the external signal transmission interface to the data sending end, so that the data sending end can determine the signal transmission deviation corresponding to the external signal transmission interface based on the actual output signal value of the external signal transmission interface and the verification sample data.

[0131] Specifically, the signal source feeds back the output signal values ​​of each external signal transmission interface to the data sending end, so that the data sending end can determine the signal transmission deviation corresponding to the external signal transmission interface based on the actual output signal value of the external signal transmission interface and the verification sample data. The method for determining the signal transmission deviation has been described in detail in S303 above and will not be repeated here.

[0132] To facilitate understanding by those skilled in the art, the above-mentioned system testing methods for nuclear power plant reactors are described in detail, such as... Figure 6 As shown, the method may include:

[0137] S605, the signal source end feeds back the actual output signal value of the external signal transmission interface to the data sending end.

[0138] S606, the data sending end obtains the actual output signal value of the external signal transmission interface fed back by the signal source end.

[0139] The actual output signal value is the signal value detected by the external signal transmission interface when the external signal transmission interface performs signal transmission operation based on the verification signal.

[0140] S607, the data sending end determines the signal transmission deviation corresponding to the external signal transmission interface based on the actual output signal value of the external signal transmission interface and the verification sample data.

[0141] S608, the data sending end acquires the raw sample data of the system to be tested.

[0142] The system to be tested is a nuclear power plant reactor system; the original sample data includes at least one of the following: electrical signal data of the system under historical operating conditions, electrical signal data configured by the user, and electrical signal data from system simulation.

[0143] S609, the data transmitting end determines the target signal transmission interface corresponding to the original sample data from the external signal transmission interface of the signal source end.

[0144] The external signal transmission interface includes a current transmission interface and a voltage transmission interface for sending detection signals to the system under test.

[0145] S610, the data transmitting end determines the signal transmission deviation corresponding to the original sample data based on the signal transmission deviation corresponding to the target signal transmission interface. Then, based on the signal transmission deviation, the original sample data is corrected to obtain corrected sample data.

[0146] S611, the data transmitter transmits the corrected sample data to the signal source.

[0147] S612, the signal source end acquires the corrected sample data transmitted by the data transmitter end.

[0148] S613, the signal source performs signal conversion processing on the corrected sample data to obtain the detection signal.

[0149] S614, the signal source end determines the target signal transmission interface corresponding to the detection signal from the external signal transmission interface.

[0150] S615, the signal source determines whether the detected signal is less than the signal transmission threshold of the corresponding target signal transmission interface. If yes, then execute S616; otherwise, execute S617.

[0151] S616, the signal source transmits the detection signal to the system under test through the target signal transmission interface, so that the system under test can perform system detection based on the detection signal.

[0152] S617, the signal source end abandons the output of the detection signal.

[0153] For example, the above-described system detection method for nuclear power plant reactors is applied to applications such as... Figure 7 Taking the system testing device of the nuclear power plant reactor shown as an example, this embodiment provides a detailed description of the system testing method for the nuclear power plant reactor. For example... Figure 7Before the nuclear power plant reactor system testing device 1 shown is actually used, the accuracy of each picoampere-level microcurrent precision source measurement unit (3) and each four-channel voltage precision source measurement unit (5) needs to be verified. Taking the verification of the picoampere-level microcurrent precision source measurement unit (3) as an example, specifically, when the data sending end (7) verifies the signal source end (1), it can control the data sample processing software (8) to send the pre-prepared verification sample data to the signal source end (1) through the lightning interface (10); the remote control module (4) of the signal source end (1) receives the verification sample data through the lightning interface (10) and sends the received verification sample data to a designated picoampere-level microcurrent precision source measurement unit (3). The picoampere-level microcurrent precision source measurement unit (3) performs signal conversion processing on the received verification sample data to obtain a verification signal, and outputs the verification signal to the outside through the BNC connector (11) (i.e., the external signal transmission interface) corresponding to the picoampere-level microcurrent precision source measurement unit (3). At this time, the digital multimeter (6) on the signal source end (1) reads the current signal flowing through the BNC connector (11). The data sample processing software (8) obtains the reading value of the digital multimeter (6) through the remote control module (4), and uses this reading value as the actual output signal value corresponding to the picoampere-level microcurrent precision source measurement unit (3) being calibrated at this time. The data sample processing software (8) compares this actual output signal value with the calibration sample data to determine the signal transmission deviation corresponding to the picoampere-level microcurrent precision source measurement unit (3). Similarly, the calibration of other picoampere-level microcurrent precision source measurement units (3) and each four-channel voltage precision source measurement unit (5) is performed in the same manner as described above, and will not be elaborated here.

[0154] When testing the system under test, the data sending end (7) can obtain the original sample data (i.e., at least one of the electrical signal data of the system under test in its historical operating state, the electrical signal data configured by the user, and the electrical signal data of the system simulation) from the data sample processing software (8). For example, if the original sample data is the electrical signal data of the system under test in its historical operating state, the data sample processing software (8) can extract it from the data sample library (9) and use the extracted data as the original sample data. The data sample processing software (8) then uses the original sample data and the predetermined picoampere levels as the basis for the test. The signal transmission deviations of the micro-current precision source measurement unit (3) and each of the four-channel voltage precision source measurement units (5) are used to correct the original sample data, obtain corrected sample data, and send it to the remote control module (4) of the signal source end (1) through the lightning interface (10). The remote control module (4) sends the received corrected sample data to the corresponding measurement unit. Each measurement unit performs signal conversion processing on the received corrected sample data to obtain a detection signal and attempts to send it out through its corresponding external signal transmission interface (i.e., BNC connector (11) and terminal connector (12)). At this time, the picoampere-level micro-current precision source measurement unit (3) determines whether the current detection signal is less than the signal transmission threshold of the corresponding external signal transmission interface (11). If so, it sends the detection signal to the system under test through the external signal transmission interface (11) corresponding to the picoampere-level micro-current precision source measurement unit (3) so that the system under test can perform system detection based on the detection signal; if not, it abandons the output of the detection signal.
