[0001] This invention relates to the field of signal processing technology, and more specifically, to an ultra-wideband multi-channel high-speed signal acquisition and recording system and a data acquisition and storage method. Background Technology
[0002] High-speed data acquisition, transmission, storage, and playback technologies have wide applications in industries, military, and other fields.
[0003] In complex application environments and scenarios, it is necessary to simultaneously sample, store, and play back multiple intermediate frequency (IF) signals with varying bandwidths. Furthermore, with the rapid development of communication technology, the content of baseband information is increasing, and its bandwidth is widening, which places new and higher demands on IF signal processing in radio frequency channels. The system must not only possess excellent performance in the face of complex application requirements and harsh electromagnetic environments, enabling high-speed processing of multiple signals, but also consider and guarantee reliability, maintainability, and operating costs. Summary of the Invention
[0004] To address the issue of insufficient flexibility in the configuration of high-speed signal acquisition, storage, and playback systems in practical applications, which cannot meet the needs of different intermediate frequencies and signal bandwidths, this application aims to propose an ultra-wideband multi-channel high-speed signal acquisition and recording system that provides flexible configurability and supports adaptation to different intermediate frequencies and various bandwidth signals. The second objective is to propose a data acquisition and storage method that stores the acquired signal data in file format for easy retrieval and management. The specific scheme is as follows: An ultra-wideband multi-channel high-speed signal acquisition and recording system includes a main control unit, a chassis unit, a storage unit, a time signal interface unit, and a signal transceiver processing unit. The chassis unit is equipped with a transmission bus for realizing high-speed signal interconnection in the system. The signal transceiver processing unit includes components that are controlled and data-connected to the main control unit: The signal conditioning module is configured to have at least two channels and has multi-channel input / output functionality, which are used to receive and transmit at least two intermediate frequency signals respectively. The signal acquisition and playback module is configured to have at least two modules, which are respectively connected to the storage unit and the two signal conditioning modules. The module is used to acquire and generate different types of intermediate frequency signals, and store the generated digital signal data in the storage unit after passing through the main control unit and / or the transmission bus. The main control unit is equipped with system software modules for controlling the working modes of each unit module, the transmission status of each data channel, and for performing specific processing on digital signal data. It is also configured with a control signal interaction interface for setting input parameters and issuing operation commands. The main control unit adaptively or under the control of operation commands performs sampling, storage, and playback processing on the input signals.
[0005] Through the above technical solution, the system can be flexibly configured to handle various intermediate frequency bandwidths and signals, and can simultaneously record at least one narrowband and wideband signal. Modules can be combined and matched according to different signal processing requirements to achieve recording and playback of different signals, meeting complex application needs. Simultaneously, the generated digital signal data is processed by the main control unit and then output to the storage unit, allowing for data storage in a pre-defined manner for easy retrieval and management later.
[0006] Furthermore, the signal conditioning module includes a multi-channel narrowband signal conditioning module and a multi-channel wideband signal conditioning module, both of which have multiple sets of switchable filter banks built in, which are used to realize the reception and transmission conditioning of at least two narrowband signals and wideband signals respectively; The signal acquisition and playback module includes a narrowband signal acquisition and playback module and a broadband signal acquisition and playback module, which are respectively connected to the multi-channel narrowband signal conditioning module and the multi-channel broadband signal conditioning module, and are used to realize the acquisition and generation of narrowband signals and broadband signals.
[0007] The above technical solutions enable flexible configuration, support switching between various intermediate frequency bandwidths, and improve system reliability.
[0008] Furthermore, the multi-channel narrowband signal conditioning module includes narrowband signal conditioning sub-modules corresponding to the two narrowband signals respectively; The narrowband signal acquisition and playback module includes two independent first acquisition and playback channels and one time signal; The narrowband signal acquisition and playback module is also equipped with a first optional unit that is connected to the main control unit for selecting different acquisition and playback signal center frequencies, sampling bits, and sampling rates.
[0009] Furthermore, the multi-channel broadband signal conditioning module includes broadband signal conditioning sub-modules corresponding to the two broadband signals respectively; The broadband signal acquisition and playback module includes two independent second acquisition and playback channels and one time signal; The broadband signal acquisition and playback module is also equipped with a second optional unit that is connected to the main control unit for selecting different acquisition and playback signal center frequencies, sampling bits, and sampling rates.
[0010] Furthermore, the signal acquisition and playback module also includes a digital signal acquisition and playback module, configured to be data-connected to the storage unit and including at least two digital fiber optic transceiver interfaces or 10 Gigabit Ethernet interfaces to complete the transmission and reception of fiber optic digital signals.
[0011] Furthermore, the storage unit is configured as a disk array that is data-connected to the transmission bus and controlled by the main control unit, for storing the digital signal data output by the signal acquisition and playback module; The chassis unit includes a PXle chassis, a power supply, and an interface / clock module.
[0012] Furthermore, the sampling rate of the narrowband signal acquisition and playback module is configured to be 240MSPS, 56MSPS and 62.5MSPS, the sampling bit depth is configured to be 8 bits or 16 bits, and the center frequency of the acquisition and playback signal is configured to be 70M / 140M / 300MHz. The maximum sampling rate of the broadband signal acquisition and playback module is configured to be 960MSPS, 1600MSPS, 2000MSPS, 4800MSPS, 5200MSPS and 5400MSPS, the sampling bit depth is configured to be 4 bits or 8 bits, and the center frequency of the acquired and played-back signal is configured to be 720M / 1.2G / 1.5G.
[0013] The above technical solutions provide a variety of sampling frequency options and combinations, effectively improving the applicability of the entire system.
[0014] Furthermore, the system software module has the following built-in features: The parameter setting algorithm is configured to set the working mode of each unit module of the system and the transmission status of each data channel based on user input. The signal acquisition and storage algorithm is configured to convert intermediate frequency signals and time signals into digital signals through synchronous acquisition and then store them in the storage unit; The signal playback algorithm is configured to synchronously play back the intermediate frequency signal recorded in the storage unit into the system after signal processing. The system operation control algorithm is configured to enable human-machine interaction, control and monitor system operation; complete communication and command transmission between various modules and units, status monitoring and information query; The data processing algorithm is configured to edit, manage, analyze, or retrieve data transmitted to the main control unit and storage unit based on specific needs.
[0015] Furthermore, the system software module is also configured with: The system self-test algorithm is configured to detect the normal operating status of each module and unit of the system based on set parameters after the system boots up; and The real-time status monitoring algorithm is configured to automatically enter the real-time status monitoring alarm working state when the system records or replays data, issue an alarm when a fault is detected, and determine whether the system has experienced data loss.
[0016] A method for acquiring and storing ultra-wideband multi-channel high-speed signal data, based on the ultra-wideband multi-channel high-speed signal acquisition and recording system described above, includes the following steps: The main control unit autonomously selects or determines the data transmission channel and parameters between the signal conditioning module and the signal acquisition and playback module based on the operation instructions received from the control signal interaction interface. After being processed by the signal conditioning module and the signal acquisition and playback module, the digital signal data is output to the main control unit via the transmission bus. The digital signal data is then processed by the data processing algorithm in the system software module and output to the storage unit. The processing method includes storing the digitized signal data in the form of a file.
[0017] With the above technical solution, the digital signal data output by the acquisition and playback module is not directly stored in the storage unit. Instead, it is processed by the algorithm built into the main control unit before being output. The digital signal data can be stored in the form of a file, and the data is what you see and what you get, which is convenient for retrieval and storage.
[0018] Compared with the prior art, the beneficial effects of this application are as follows: By integrating multiple broadband and narrowband channels and their corresponding signal acquisition and playback modules, the signal acquisition and recording system of this application can simultaneously acquire and record multiple high-speed broadband and narrowband signals. Users can flexibly configure various parameters as needed to achieve data acquisition, storage, and playback of multiple bandwidths and multiple intermediate frequencies, making it highly configurable. Each unit adopts a modular design with standard interfaces, such as acquisition cards, playback cards, and acquisition-playback cards, which facilitates maintenance and improves system reliability.

Detailed Implementation
[0021] With the rapid development of communication technology, the content of baseband information is becoming increasingly rich, and its bandwidth is also becoming increasingly wide, some even exceeding 2000MHz. This places new and higher demands on intermediate frequency (IF) signal processing in radio frequency (RF) channels. Previously commonly used IF frequencies such as 70MHz and 140MHz are clearly insufficient to meet the system's bandwidth requirements, necessitating an increase in IF frequency to satisfy the larger bandwidth demands. To meet the complex application needs and the requirements for high-speed data acquisition, storage, and playback under various harsh environments, this application proposes an ultra-wideband multi-channel high-speed signal acquisition and recording system.

[0023] To achieve the above-mentioned key technologies, the present application will be further described in detail below with reference to the embodiments and figures, but the implementation of the present application is not limited thereto.
[0024] like Figure 1 As shown, the ultra-wideband multi-channel high-speed signal acquisition and recording system described in this application mainly includes a main control unit 100, a chassis unit 200, a storage unit 300, a time signal interface unit 400, and a signal transceiver processing unit 500.
[0025] The main control unit 100 includes a main control server as the system platform, configured with a 4-core, 8-thread CPU with a maximum turbo frequency of 4.5GHz, 32GB DDR4 memory, a 500GB SSD, and a PCIe x16 interface on the back panel, supporting PCIe Gen1, Gen2, and Gen3. The main control unit 100 contains system software modules for controlling the operating modes and data transmission status of each unit module, and is configured with a control signal interaction interface for input parameter settings and operation commands. It adaptively or under the control of operation commands, sampling, storing, and playing back input signals. The main control unit 100 also handles the system's display and analysis functions, completing functions such as parameter configuration for signal acquisition and playback, channel configuration, display of the operating status of each system unit, and display of analysis results.
[0026] The chassis unit 200 includes a PXle chassis, a power supply system, and an interface / clock module. For example... Figure 1 and Figure 2 As shown, the chassis configuration in this application is an 18-slot PXIe chassis, equipped with a transmission bus for high-speed signal interconnection in the system, such as the PCIe Gen3 bus, supporting standard 3UPXIe modules, and conforming to the IEEE 1101.10 / IEEE 11 standard in size. The chassis configuration supports a maximum of 16 peripheral cards, with all peripheral slots providing PCIe Gen3x8 connections. The system bandwidth is configured as 24GB / s, with peripheral slot bandwidth of 8GB / s, providing a PXI timing bus and supporting the distribution of external reference clocks. The interface / clock module is mainly used for the system's external interfaces, such as timecode input / output, external clocks, and trigger processing. It also provides clock references to various subsystems within the system.
[0027] The storage unit 300 is configured as a disk array connected to the transmission bus and controlled by the main control unit 100, and is used to store the digital signal data output by the signal acquisition and playback module 520. In this embodiment, the storage capacity of the data storage unit 300 can be configured to 40TB or more, adopting a PXIe-3U standard structure, with a read / write rate ≥5GB / s; the signal acquisition results are stored in file format without the need for transfer storage; and the computer system can access, play back, retrieve, extract, and analyze the data on the storage module.
[0028] The time signal interface unit 400 is a time and clock interface unit, adopting a single-slot PXIe-3U standard structure; it supports PXI timing slot, with 1 clock input and 18 outputs, and 3 trigger inputs and 18 outputs; it receives and distributes input time codes during acquisition, selects and drives multiple time codes during playback, and completes the IRIG-B signal transceiver interface and the distribution of reference clock.
[0029] like Figure 2 and Figure 3 As shown, the signal transceiver processing unit 500 includes a signal conditioning module 510 and a signal acquisition and playback module 520 that are controlled and connected to the main control unit 100.
[0030] The signal conditioning module 510 is configured to have at least two modules and has multi-channel input / output functions, which are used to receive and transmit at least two intermediate frequency signals respectively.
[0031] Typically, the intermediate frequency (IF) signal input conditioning module is designed to ensure that the IF signal falls within the optimal effective acquisition dynamic range of the ADC acquisition card through the AGC (Automatic Gain Control) circuit before entering the high-speed digital conversion acquisition card, thereby improving the dynamic range of the system and providing input protection for the IF acquisition card.
[0032] In the embodiments of this application, combined with Figure 2 As shown, the signal conditioning module 510 includes a multi-channel narrowband signal conditioning module 511 and a multi-channel wideband signal conditioning module 512, both of which have multiple sets of switchable filter banks built in, used to receive and transmit at least two narrowband signals, such as measurement and control signals, and at least two wideband signals, such as data transmission signals, respectively. The signal acquisition and playback module 520 includes a narrowband signal acquisition and playback module 521 and a wideband signal acquisition and playback module 522, which are data-connected to the multi-channel narrowband signal conditioning module 511 and the multi-channel wideband signal conditioning module 512, respectively, for acquiring and generating narrowband and wideband signals, and storing the generated digital signal data in the storage unit 300. The multi-channel narrowband signal conditioning module 511 includes narrowband signal conditioning sub-modules corresponding to the two narrowband signals respectively. The narrowband signal acquisition and playback module 521 is mainly used to acquire and generate two control signals, including two independent first acquisition and playback channels and one time code. The narrowband signal acquisition and playback module 521 is also configured with a first selection unit controlled and connected to the main control unit 100, used to select different acquisition and playback signal center frequencies, sampling bits, and sampling rates. In this embodiment, the sampling rate of the narrowband signal acquisition and playback module 521 is configured to be 240MSPS, 56MSPS, and 62.5MSPS, the sampling bit depth is configured to be 8 bits or 16 bits, and the acquisition and playback signal center frequency is configured to be 70MHz / 140MHz / 300MHz, supporting input conditioning and output conditioning of multiple intermediate frequency and bandwidth signals of 70MHz / 140MHz / 300MHz.
[0033] The multi-channel broadband signal conditioning module 512 includes broadband signal conditioning sub-modules corresponding to the two broadband signals respectively. The broadband signal acquisition and playback module 522 is mainly used to acquire and generate two data transmission signals, including two independent second acquisition and playback channels and one timecode. The broadband signal acquisition and playback module 522 is also configured with a second optional unit connected to the main control unit 100 for selecting different acquisition and playback signal center frequencies, sampling bits, and sampling rates. In this embodiment, the maximum sampling rate of the broadband signal acquisition and playback module 522 is configured to be 960MSPS, 1600MSPS, 2000MSPS, 4800MSPS, 5200MSPS, and 5400MSPS, the sampling bit depth is configured to be 4 bits or 8 bits, and the acquisition and playback signal center frequency is configured to be 720MHz / 1.2GHz / 1.5GHz, supporting input conditioning and output conditioning of multiple intermediate frequency and bandwidth signals of 720MHz / 1.2GHz / 1.5GHz.
[0034] Both the first and second optional units mentioned above are connected to the main control unit 100. The data acquisition and playback in the broadband signal acquisition and playback module 522 and the narrowband signal acquisition and playback module 521 can utilize existing signal acquisition and playback boards, enabling the acquisition of a 6.4GS / s@12bit analog signal per channel on a single board, and playback of a maximum 9GS / s@8bit signal per board. The boards integrate a Xilinx UltraScale KUC060 large-scale FPGA, which can be upgraded in the future to implement other real-time signal processing functions required by the system.
[0035] like Figure 3 As shown, the signal acquisition and playback module 520 also includes a digital signal acquisition and playback module 523, which is configured to be data connected to the storage unit 300 and includes at least two digital fiber optic transceiver interfaces or 10 Gigabit Ethernet interfaces. It supports the transmission protocols of 10 Gigabit switches and digital switching matrices, and completes the transmission and reception of fiber optic digital signals. It is mainly used to realize the acquisition and generation of two fiber optic signals.
[0036] In the system function design, the system software module has built-in system self-test algorithm, parameter setting algorithm, signal acquisition and storage algorithm, signal playback algorithm, real-time status monitoring algorithm, system operation control algorithm and data processing algorithm.
[0037] The system self-test algorithm is configured so that after system startup, the system control software automatically enters the system self-test state to check whether the initial system state and recording / playback working state are normal. The system software automatically completes the identification and detection of the acquisition / playback RF conditioning module, acquisition / playback card, and memory card. It adaptively configures the corresponding functional parameters of the relevant boards, such as frequency, channels, sampling rate, trigger mode, and clock.
[0038] The parameter setting algorithm is configured to set relevant operating parameters such as task name, signal sampling rate, and recording start method. The recording methods are: preset recording or manual start / stop recording. For preset recording, a recording start time needs to be input according to the task requirements; the control system automatically completes the recording based on the input start time.
[0039] The signal acquisition and storage algorithm is configured to synchronously acquire and convert intermediate frequency signals and time code signals into digital signals, which are then transmitted via a bus and stored in a large-capacity disk array by the main control unit 100. Simultaneously, the control system saves parameter and function settings to the disk array. Based on the selected recording method, the recording start and stop methods are determined; if time-preset recording is used, the start and stop times are entered. The control system calculates and displays the remaining disk array capacity and storage time based on the user-selected sampling rate.
[0040] The signal playback algorithm is configured to process the intermediate frequency signal recorded in the disk array through signal processing, digital-to-analog conversion, filtering and amplification; and to synchronously play back the time code signal to the measurement and control system through a converter from TTL level to RS-422A level.
[0041] When the real-time status monitoring algorithm is configured to automatically enter the real-time status monitoring alarm working state during system recording or playback, the system monitors the input and output signal levels of the circuit board and the recording and playback working status, receives control commands from the monitoring computer, issues an alarm when a fault is detected, and determines whether the system has experienced data loss.
[0042] The system operation control algorithm is configured to enable human-machine interaction, control and monitor system operation; complete communication and command transmission between various modules and units, status monitoring and information query; The data processing algorithm is configured to edit, manage, analyze, or retrieve the recorded data transmitted to the main control unit 100 and the storage unit 300 based on specific needs.
[0043] Based on the aforementioned ultra-wideband multi-channel high-speed signal acquisition and recording system, this application also proposes an ultra-wideband multi-channel high-speed signal data acquisition and storage method, which simultaneously realizes the acquisition and processing of data with multiple bandwidths and multiple intermediate frequencies, mainly including the following steps: S1, the main control unit 100 autonomously selects or determines the data transmission channel and parameters between the signal conditioning module 510 and the signal acquisition and playback module 520 based on the operation instructions received from the control signal interaction interface, in order to adapt to different signal acquisition and storage requirements.
[0044] S2, after being processed by the signal conditioning module 510 and the signal acquisition and playback module 520, the digital signal data is output to the main control unit 100 via the transmission bus. The digital signal data is then processed by the data processing algorithm in the system software module and output to the storage unit 300. The processing method includes storing the digital signal data in the form of a file, thereby realizing data management based on the Windows system.
[0045] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
