Description

Technical Field

[0001] The present application relates to the field of signal processing, and in particular to an electronic equipment architecture based on three-layer four-link multifunctional agility. Background Art

[0002] Future space-based / air-based information systems will develop towards full-spectrum, multi-functional, real-time and intelligent directions. These systems are required to cover all required frequency bands, integrate communication, navigation, remote sensing and other functions, be able to acquire, process and transmit information in real time, and be able to perform tasks intelligently and autonomously.

[0003] The literature (Integrated integrated spatial information system based on “Software Star” [J]. Electronic Science and Technology Review, 2004 (4): 15-22.) proposed a scheme called “Software Star”. Figure 1 The "Software Satellite" system primarily consists of an antenna array, an antenna switch matrix, a software-defined radio platform (SDR), and a payload control / data processing computer. The "Software Satellite" system's broadband antenna is implemented through frequency banding, encompassing four sub-bands: UHF, L / S, C, and Ku bands, covering 0.1 to 18 GHz. The antenna switch matrix distributes RF signals. Based on mission requirements and equipment integrity, the electromagnetic signals received by antennas in each frequency band are fed into the RF input of the SDR platform for subsequent processing. The SDR platform then distributes the RF signals output by antennas in each frequency band, transmitting them to the ground or air as required, fulfilling functions such as communication relay, active radar detection, and electronic jamming. The SDR platform is the core component of the "Software Satellite" payload, executing software uploaded from the ground command and control system to perform corresponding tactical functions. The software radio universal platform mainly consists of two parts, namely the broadband universal RF front-end and the high-speed digital signal processing unit. The software radio universal platform works in a full-band mode and can operate in any frequency band of UHF, L / S, C and Ku bands. Figure 1The four software radio general platforms shown in the diagram can operate in parallel and provide redundant backup for each other. During reception, the broadband universal RF front end converts the RF signal into a broadband IF signal through common analog operations such as signal amplification, frequency conversion, and filtering. During transmission, it converts the broadband IF signal into RF signals of various frequency bands. The high-speed digital signal processing unit primarily performs digitization (A / D) of the broadband IF signal and performs digital down-conversion (DDC) based on the signal center frequency and bandwidth, including orthogonal transformation, digital filtering, and multi-rate conversion. Finally, signal characteristic parameters such as instantaneous amplitude, instantaneous phase, and instantaneous frequency are extracted and sent to the DSP unit for processing by signal processing software uploaded from the ground, fulfilling the corresponding tactical functions. The payload control and data processing computer primarily controls and manages the payload's available resources, enabling the various tactical functions assigned to the "software satellite" by the ground control center.

[0004] However, the "software satellite" approach transmits analog signals into the cabin and then digitizes them on a software-defined radio (SDR). This approach suffers from significant power loss in analog transmission, introducing phase noise, low detection accuracy, and impacted processing performance. The analog antenna can only form one receive beam at a time and lacks multi-beam capability. Furthermore, the antenna is connected to the onboard processing equipment by heavy cables, which increases the overall weight of the satellite. The offboard antenna is independent and lacks aperture synthesis design, nor does it reuse RF front-end resources. This results in wasted resources, heavy weight, and poor reliability, making it unsuitable for lightweight and efficient utilization of onboard resources. The SDR's limited processing resources (only DSP) cannot accommodate the rapidly evolving and diverse functions of space-based and airborne payloads. While processing resources are not tied to the antenna, they are switched solely through a switch matrix, limited to switching between the four SDRs. This lacks fine-grained module-level or chip-level shared redundancy for processing resources. Software-defined functions are inflexible, and the satellite lacks intelligent autonomy, requiring support from the ground. The satellite lacks a function-agile module to coordinate resources and deploy individual or combined functions.

[0005] In view of this, in view of the future development trend of full-spectrum, multi-functional, real-time and intelligent space-based / air-based information systems, it is urgent to provide an electronic equipment architecture based on three layers and four chains with multi-functionality and agility, which supports various types of functional applications of space-based / air-based information systems such as communication, navigation, remote sensing, detection, routing and computing integration, and meets the construction of space-based / air-based information systems integrating communication, navigation and remote sensing in my country.

[0031] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0032] See also Figure 2 , Figure 2 An architectural diagram of an electronic equipment architecture based on a three-layer, four-link, multifunctional agile architecture provided in an embodiment of the present application.

[0033] like Figure 2As shown, the electronic equipment includes: three layers of equipment, which are responsible for the acquisition, transmission and processing of information; four links, which are responsible for the operation guarantee of the system; a multifunctional agile module, which is responsible for the deployment, rapid switching and collaborative work of no less than 6 types of functions such as communication, navigation, remote sensing, detection, routing networking, and computing fusion; an autonomous operation control module, which is the core of the entire system and is responsible for issuing task instructions and coordinating with other modules; and an electromechanical thermal information support module, which is responsible for providing information resource guarantees for installation location, energy, and navigation positioning for electronic equipment.

[0034] Specifically, the three-layer equipment includes the first layer of the extravehicular digital array comprehensive aperture module; the second layer of the optical fiber transmission and all-optical switching module; and the third layer of the in-cabin heterogeneous resource processing pool module.

[0035] In the embodiment of the present application, the extravehicular digital array comprehensive aperture module is a device that integrates multi-band distributed comprehensive apertures, including two parts: a comprehensive front-end device and a multi-band transceiver device, which is used to obtain information about the comprehensive apertures of multiple frequency bands and digitally process the obtained information using a digital array system. Figure 3 , Figure 3 This is an architectural diagram of an extravehicular digital array synthetic aperture module based on a three-layer, four-link, multifunctional, agile electronic equipment architecture provided in an embodiment of the present application.

[0036] The extravehicular digital array integrated aperture module includes integrated front-end equipment and multi-band transceiver equipment, which is used to integrate the multi-band distributed integrated aperture. The integrated front-end equipment includes wavelength division multiplexing / demultiplexing, up-conversion / down-conversion, optoelectronic / electro-optical conversion, wave control unit and local oscillator / clock; the multi-band transceiver equipment is composed of antenna apertures of UHF, L, S, C / X, Ku, Ka, U / V, and W.

[0037] The array of integrated aperture transceiver coordinates the working frequency to achieve wide-band RF coverage, forming integrated aperture transceiver for UHF, L, S, C / X, Ku, Ka, U / V, W and other frequency bands.

[0038] In an embodiment of the present application, in order to meet the transmission requirements of broadband signals after digitization outside the cabin and high-speed transmission into the cabin processing resource pool, 16 / 32 / 64 wavelength division multiplexing technology is adopted. A single-core optical fiber can transmit 196 / 392 / 784Gbps of data, which can meet the transmission requirements of various functions from the digital array aperture outside the cabin to the heterogeneous resource processing resource pool inside the cabin.

[0039] The optical fiber through-cabin transmission network mainly utilizes the characteristics of optical cable, such as light weight, large bandwidth, high transmission rate and easy signal multiplexing, to realize the transmission of various signals such as digital optical signals, RF analog optical signals, local oscillator signals, control and synchronization signals between the integrated aperture outside the cabin and the processing resource pool inside the cabin.

[0040] The optical fiber transmission and all-optical switching module is used for information transmission between the off-cabin digital array comprehensive aperture module and the on-cabin heterogeneous resource processing pool module. It is responsible for the information transmission between the off-cabin distributed comprehensive aperture digital signal and the on-cabin processing resource pool after it enters the cabin through the optical fiber. Figure 4 , Figure 4 This is an architectural diagram of an optical fiber transmission and all-optical switching module based on a three-layer, four-link, multifunctional, and agile electronic equipment architecture provided in an embodiment of the present application.

[0041] The optical fiber transmission and all-optical switching module includes an optical power amplification module, an array optical switching network, and a management and control module, and is used for receiving and transmitting digital signals.

[0042] The all-optical switching network completes the collection, distribution and flexible exchange of digital signals from the distributed integrated aperture outside the cabin after entering the cabin through optical fiber and between the signals and the processing resource pool inside the cabin.

[0043] It consists of optical power amplifier module, array optical switching network, management and control module and other parts, and has the function of receiving and transmitting digital optical signals.

[0044] The main function of digital optical signal reception is to transmit and exchange the digital optical signals input by the distributed comprehensive aperture, select the optical signals that need to be processed simultaneously and send them to the processing resource pool in the cabin, so as to realize the ability to select multiple optical fibers from the input optical fibers for back-end processing.

[0045] The selected multiple optical fibers are amplified by the optical power amplifier module to compensate for the loss introduced by the optical cables passing through the cabin and the insertion loss of the devices. Finally, the amplified multiple optical signals are sent to the processing resource pool in the cabin for signal processing and data processing.

[0046] In an embodiment of the present application, the in-cabin heterogeneous resource processing pool module includes at least five heterogeneous resource processors and a high-speed switching network, which is used to form a signal data processing resource pool through resource virtualization of at least five heterogeneous processing resources to meet the needs of high-speed signal processing and data processing of various functions.

[0047] The in-cabin heterogeneous resource processing pool module uses VPX boards, including FPGA processing modules, DSP processing modules, CPU processing modules, GPU processing modules, and AI processing modules. A high-speed switching network is used between the VPX boards to exchange information, enabling collaborative processing of signals and data. A low-speed measurement and control network is used to monitor module resources and implement task allocation. Figure 4 , Figure 4 This is an architectural diagram of an in-cabin heterogeneous resource processing pool module based on a three-layer, four-link, multifunctional, and agile electronic equipment architecture provided in an embodiment of the present application.

[0048] The heterogeneous processing resource pool equipment uses VPX boards, which include multiple modules of five types, including FPGA processing modules, DSP processing modules, CPU processing modules, GPU processing modules, and AI processing modules. Through resource virtualization technology, a general signal data processing pool is formed to complete signal processing and data processing functions. Through software function configuration, functional program loading for different test tasks is realized, which can support the completion of digital frequency conversion, waveform generation, beamforming, real-time imaging, signal detection, parameter measurement, modulation identification, information distribution, etc. A high-speed switching network is used for information exchange between boards to achieve collaborative processing of signals and data. The low-speed measurement and control network monitors module resources and allocates tasks. The high-speed switching network uses a RapidIO network to connect all modules of five types, including FPGA processing modules, DSP processing modules, CPU processing modules, GPU processing modules, and AI processing modules, to form a general signal data processing pool to meet the needs of high-speed signal processing and data processing.

[0049] Specifically, the four links include a power supply and distribution link, a telemetry and remote control link, a signal information link, and a reference synchronization link.

[0050] In the embodiments of this application, the power supply and distribution link, on the one hand, adopts a radial power supply design to provide control and basic information security for system operation; on the other hand, it uses a constant power-on automatic temperature control method to meet the storage temperature requirements of the equipment. In actual applications, the power supply and distribution link adopts a radial power supply design, with each device independently designed to avoid interference between the various devices in the payload. To adapt to the space-based / airborne ambient temperature, a constant power-on automatic temperature control method is used to meet the storage temperature requirements of the equipment.

[0051] The telemetry and remote control link is used to execute corresponding work instructions for extravehicular and intravehicular equipment via a low-speed serial bus. These work instructions include control management, equipment status monitoring, equipment testing and maintenance, file injection and updating, and task scheduling and execution. In actual applications, tasks are carried out under the planning of the ground system, and control management, equipment status monitoring, equipment testing and maintenance, file injection and updating, and task scheduling and execution of extravehicular and intravehicular equipment are completed via the low-speed serial bus. During the task execution process, relevant equipment telemetry information, as well as the reception and execution results of remote control commands, are fed back to the ground system.

[0052] The signal information link is used to coordinate the high-speed signal stream transmission and all-optical link exchange of each sub-aperture outside the cabin. The signal information link includes high-speed signal stream transmission and all-optical link exchange, and is used to receive and send information streams. The high-speed signal stream transmission is used for high-speed signal transmission between the distributed synthetic aperture outside the cabin and the heterogeneous resource pool inside the cabin; the all-optical link exchange is used for information exchange between external and internal signals.

[0053] Signal information links are coordinated into two modes: high-speed signal flow exchange and all-optical link exchange. All-optical link exchange is used for high-speed transmission of signals between the cabin and outside. High-speed signal flow exchange is a key guarantee for resource pooling, and Rapid IO networking is used to ensure the high-speed signal processing and exchange requirements of the heterogeneous resource pool within the cabin.

[0054] The payload information flow includes the receiving information flow and the sending information flow. The receiving information flow is designed as follows. Figure 6 , Figure 6 This is a signal information link diagram of a three-layer, four-link, multi-functional, and agile electronic equipment architecture provided in an embodiment of the present application. It should be noted that the sending process is similar to the receiving process, and the embodiment of the present application will not be described in detail here.

[0055] The RF signal from the array is down-converted through the receiving channel and output as an intermediate frequency, which is sampled and converted into a digital signal by a high-speed ADC chip. After serialization, 8b / 10b encoding and synchronization signal insertion, a high-speed serial data stream is formed, which is converted into a digital optical signal for transmission through an electro-optical conversion device. After wavelength division multiplexing, a high-speed optical fiber signal is formed. The optical fiber signal enters the optical switching matrix module for switching and selection, and then enters the optical amplifier module for optical signal amplification, wavelength division multiplexing and optoelectronic conversion, forming an electrical signal connection and entering the digital signal processing module. The signal processing module completes digital signal processing of mission functions and multi-source intelligence information fusion and other data processing.

[0056] The reference synchronization link includes a spatial reference, a time reference, and a frequency reference. The spatial reference meets various functional requirements through coordinate system conversion. The time reference generates high-precision video signals and uses time scales for synchronization to coordinate the operation of various hardware devices and functions. The frequency reference is used to generate local oscillator signals, sampling clock signals, and correction signals corresponding to frequency conversion in different frequency bands.

[0057] In practical applications, the time base is configured with high-precision time and frequency equipment, using time scales for synchronization and coordination of hardware devices and functions. By using the 1PPS signal as the operating cadence, the time, position, and attitude information at any moment can be obtained by extrapolation between adjacent pulse-per-second signals.

[0058] Spatial reference: Through the transformation among the three coordinate systems of geocentric coordinate system, aircraft coordinate system and antenna coordinate system, the position coordinates are transformed between the antenna spherical coordinate system and the antenna rectangular coordinate system, between the antenna rectangular coordinate system and the aircraft coordinate system, and between the aircraft coordinate system and the geocentric coordinate system to meet the use requirements of various functions.

[0059] Frequency reference: The rubidium clock module generates a 10MHz reference signal, and the frequency standard module synthesizes a 100MHz frequency reference signal. The frequency synthesizer module splits the 100MHz reference signal and uses frequency synthesis to generate the local oscillator signal, sampling clock signal, and correction signal required for frequency conversion in each frequency band.

[0060] Specifically, the multifunctional agile module is used to achieve autonomous management of various functions. Under the unified management of the operation control module, it establishes a mapping relationship between functions and devices through the resource abstraction modeling method, coordinates the information of the external digital array comprehensive aperture module, the optical fiber transmission and all-optical switching module, and the internal heterogeneous resource pool module, and realizes the agility of device functions through software loading. Figure 7 , Figure 7 A schematic diagram of the working process of a multifunctional agile module of an electronic equipment architecture based on a three-layer four-link multifunctional agile system provided in an embodiment of the present application.

[0061] In practical applications, the multifunctional agile module is the core of software-defined functionality, responsible for resource mapping, hardware deployment, and functional reconfiguration of functional software. In terms of software design, system functionality is defined through abstracting software and hardware resource models, clarifying their configuration relationships, software loading, and deploying functional operations. The equipment supports the deployment and reconfiguration of no fewer than six major functional categories: communications, navigation, remote sensing, detection, routing and networking, and computing convergence.

[0062] In an embodiment of the present application, the electronic equipment further includes an operation control module for issuing task instructions and coordinating the operation of the extravehicular digital array synthetic aperture module, the optical fiber transmission and all-optical switching module, and the intravehicular heterogeneous resource pool module. The operation control module also monitors device status, service information, and resource usage, and performs fault diagnosis and recovery.

[0063] The platform's electromechanical and thermal information support module is used to provide installation location, energy, and navigation and positioning information resources for the electronic devices. Specifically, the space-based / airborne platform provides the electronic equipment with the installation location, installation conditions, and cooling conditions, provides busbar power, transmits platform parameters such as position, attitude, and time, and provides pulse-per-second signals to the electronic equipment.

[0064] The multifunctional agile electronic equipment architecture based on three layers and four links provided in the embodiment of the present application can support various types of functional applications such as communication, navigation, remote sensing, detection, routing, and computing integration of space-based / air-based information systems. It has the characteristics of wide bandwidth, support for real-time processing on board, and multifunctional agile switching, which can meet the construction of space-based / air-based information systems integrating communication, navigation, and remote sensing in my country.
