Description

Technical Field

[0001] This invention relates to the field of signal detection technology, and more specifically, to a dynamically configurable system maintenance detection method and apparatus. Background Technology

[0002] As secondary radar ground interrogator systems become increasingly complex, system maintenance and testing become crucial. A good system maintenance and testing method can quickly help locate system faults and save debugging and troubleshooting time.

[0003] like Figure 1 As shown, existing testing methods output critical system signals to test pins or connectors on the front panel of the chassis (hereinafter referred to as test points). These signals are then measured using an oscilloscope or similar instruments to determine the system or module's operating status, thereby pinpointing the cause of the fault. Therefore, existing testing methods require prior identification of critical signals, followed by outputting the signal to be tested to the front panel test points via cables. When there are many modules, one approach to test the signals of each module is to add test points to each module, such as... Figure 1 As shown by the dotted line, another method is to output the detected signals from each module to the same detection point, such as... Figure 1 As shown by the solid line.

[0004] However, existing system maintenance and testing methods require individual hardware adjustments for each functional device, hindering portability between projects. Furthermore, current testing methods often rely on prior experience to output critical signals, limited by the number of hardware pins, and cannot output other system signals, lacking scalability. If adjustments to the testing status are needed later, it increases additional time and manpower costs. Additionally, existing methods often have testing points for each module or output signals from all modules to the same testing point, resulting in system redundancy and hindering lightweight and miniaturized design. Therefore, researching and designing a dynamically configurable system maintenance and testing method and device that overcomes these shortcomings is a pressing issue we urgently need to address. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a dynamically configurable system maintenance and testing method and apparatus. This method is highly integrated and can complete the detection and output of all tested signals of the system, including analog and discrete signals, using fewer cables. It has the advantages of strong scalability and good portability, making it easy to apply to system maintenance and testing in different projects.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] Firstly, a dynamically configurable system maintenance detection method is provided, which is applied to the detection of discrete signals in a secondary radar ground interrogator system, and includes the following steps:

[0008] The interface software establishes a list of discrete signals that need to be detected in each functional module, and maps the list information selected from the signal list through a preset mapping table. The mapped data is then sent to each functional module in the form of a message.

[0009] The FPGA in the functional module parses the mapping table message, and then transmits the corresponding discrete signal under test to the functional module with test points according to the mapping table.

[0010] Based on the mapping table in the functional module configured with test points, all the discrete signals under test are transmitted to the same test point to realize the detection of discrete signals during system maintenance.

[0011] Furthermore, the functional module uses a time-division multiplexing method to output the measured discrete signal.

[0012] Furthermore, the functional modules can transmit at most two discrete signals under test simultaneously.

[0013] Furthermore, the functional module configured with test points is the module with the most communication lines among all functional modules.

[0014] Secondly, a dynamically configurable system maintenance detection device is provided, which is applied to the detection of discrete signals in a secondary radar ground interrogator system, including:

[0015] The parameter configuration module is used to create a list of discrete signals that need to be detected in each functional module through the interface software, and to map the list information selected from the signal list through a preset mapping table, and then send the mapped data to each functional module in the form of a message.

[0016] The signal filtering module is used to parse the mapping table message through the FPGA in the functional module, and then transmit the corresponding discrete signal under test to the functional module with test points according to the mapping table.

[0017] The signal processing module is used to transmit all the discrete signals under test to the same test point according to the mapping table in the functional module configured with test points, so as to realize the detection of discrete signals during system maintenance.

[0018] Furthermore, the measured discrete signal is sent to the underlying FPGA via parameters, and the underlying FPGA outputs the signal to the monitoring point on the front panel of the chassis via matrix mapping.

[0019] Thirdly, a dynamically configurable system maintenance detection method is provided, which is applied to the detection of analog signals in a secondary radar ground interrogator system, and includes the following steps:

[0020] The interface software establishes a list of analog signals that need to be detected in each functional module, and maps the list information selected from the signal list through a preset mapping table. The mapped data is then sent to each functional module in the form of a message.

[0021] The FPGA in the functional module parses the mapping table message and then selects and processes the corresponding analog signal under test according to the mapping table.

[0022] If the selected analog signal to be tested is the first analog signal that has already been digitally sampled, then the first analog signal will be converted from digital to analog signal through a DAC device and the analog signal will be output to the test point.

[0023] If the selected analog signal to be tested is a second analog signal that has not been digitally sampled, the second analog signal is output to the test point via the detector by controlling the analog signal switch selection signal, so as to realize the detection of analog signals during system maintenance.

[0024] Furthermore, the functional module uses a time-division multiplexing method to output the measured analog signal.

[0025] Furthermore, each of the aforementioned functional modules is configured with test points.

[0026] Fourthly, a dynamically configurable system maintenance and detection device is provided, which is used for detecting analog signals in a secondary radar ground interrogator system, including:

[0027] The parameter configuration module is used to create a list of analog signals that need to be detected in each functional module through the interface software, and to map the list information selected from the signal list through a preset mapping table, and then send the mapped data to each functional module in the form of a message.

[0028] The signal selection module is used to parse the mapping table message through the FPGA in the functional module, and then select the corresponding analog signal to be tested according to the mapping table.

[0029] The sampling output module is used to convert the selected analog signal to a digital signal and output the analog signal to the test point through a DAC device when the selected analog signal to be tested is the first analog signal that has been digitally sampled.

[0030] The direct output module is used to output the second analog signal to the test point via a detector by controlling the analog signal switch selection signal when the selected analog signal is a second analog signal that has not been digitally sampled, so as to realize the detection of analog signals during system maintenance.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this invention are only for explaining this invention and are not intended to limit this invention.

[0044] Example 1: A dynamically configurable system maintenance detection method, such as Figure 2 As shown, this method is applied to the detection of discrete signals in a secondary radar ground interrogator system, and includes the following steps:

[0045] Step 1: Establish a list of discrete signals that need to be detected in each functional module through the interface software, and map the list information selected from the signal list through a preset mapping table. Then, send the mapped data to each functional module in the form of a message.

[0046] Step 2: The FPGA in the functional module parses the mapping table message, and then transmits the corresponding discrete signal under test to the functional module with test points according to the mapping table.

[0047] Step 3: Based on the mapping table in the functional module with the configured test points, all the discrete signals under test are transmitted to the same test point to realize the detection of discrete signals during system maintenance.

[0048] In this embodiment, the functional module uses a time-division multiplexing method to output the discrete signal under test, which can realize the simultaneous output of multiple signals and reduce the number of cables.

[0049] In a secondary radar ground interrogator system, the interaction between various functional modules is generally achieved through cable communication. To avoid a large number of cables between functional modules and to enable backup functions, two cables are typically arranged between functional modules, which can simultaneously transmit two discrete signals being measured.

[0050] In this embodiment, the functional module configured with test points is generally selected from all functional modules, which is the module with the most communication lines, that is, usually the core processing module.

[0051] Example 2: A dynamically configurable system maintenance detection device, which implements a dynamically configurable system maintenance detection method described in Example 1, such as... Figure 3 As shown, it includes a parameter configuration module, a signal filtering module, and a signal processing module.

[0052] The system includes several modules: a parameter configuration module, a signal list for each functional module to detect discrete signals, a parameter configuration module, a signal filtering module, a signal processing module, a signal processing module, and a signal processing module. The parameter configuration module is used to parse the signal processing module's message using the FPGA within the functional module and then transmit the corresponding discrete signal to the functional module with the configured test point. The signal processing module is used to transmit all the discrete signals to the same test point according to the mapping table in the functional module with the configured test point, thus enabling the detection of discrete signals during system maintenance.

[0053] It should be noted that the discrete signal under test is sent to the underlying FPGA through parameters, and the underlying FPGA outputs the signal to the monitoring point on the front panel of the chassis through matrix mapping.

[0054] Example 3: A dynamically configurable system maintenance detection method, such as Figure 4 and Figure 5 As shown, this method is applied to the detection of analog signals in a secondary radar ground interrogator system, and includes the following steps:

[0055] Step 1: Use the interface software to create a list of analog signals that need to be detected in each functional module, and use a preset mapping table to map the list information selected from the signal list. Then send the mapped data to each functional module in the form of a message.

[0056] Step 2: The FPGA in the functional module parses the mapping table message, and then selects and processes the corresponding analog signal under test according to the mapping table;

[0057] Step 3: If the selected analog signal to be tested is the first analog signal that has already been digitally sampled, then the first analog signal is converted from digital to analog signal through a DAC device and the analog signal is output to the test point;

[0058] Step 4: If the selected analog signal to be tested is a second analog signal that has not been digitally sampled, the second analog signal is output to the test point via the detector by controlling the analog signal switch selection signal, so as to realize the detection of analog signals during system maintenance.

[0059] In this embodiment, each of the functional modules is configured with a test point. The functional modules use a time-division multiplexing method to output the simulated signal under test, which can realize the simultaneous output of multiple signals and reduce the number of cables.

[0060] Example 4: A dynamically configurable system maintenance detection device, which implements a dynamically configurable system maintenance detection method described in Example 3, such as... Figure 6As shown, it includes a parameter configuration module, a signal selection module, a sampling output module, and a direct output module.

[0061] The system includes several modules: a parameter configuration module, a signal selection module, and a direct output module. The parameter configuration module uses an interface software to create a list of analog signals to be detected in each functional module. It maps the selected information from the list using a pre-defined mapping table and then sends the mapped data to each functional module in message form. The signal selection module uses the FPGA within the functional module to parse the mapping table message and select the corresponding analog signal to be tested. The sampling output module converts the selected analog signal (which has already undergone digital sampling) to an analog signal via a DAC and outputs the analog signal to the test point. The direct output module outputs the selected analog signal (which has not undergone digital sampling) to the test point via a detector by controlling the analog signal's selection switch, thus enabling the detection of analog signals during system maintenance.

[0062] Working Principle: Due to hardware limitations, the number of signals detected by each module is also limited. A mapping table is used to complete the time-division output of discrete and analog signals, thereby achieving the output of the required monitoring signals. This method reduces the number of interconnecting cables between modules and simplifies system design. The method described in this invention has a high degree of integration, and can complete the detection and output of all measured signals of the system, including analog and discrete signals, with fewer cables. This method has the advantages of strong scalability and good portability, making it easy to apply to system maintenance and testing in different projects. In addition, it reduces the number of hardware detection interfaces on the front panel, thereby reducing the number of internal cable connections, indirectly improving system stability, and facilitating lightweight and miniaturized system design.

[0063] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
