Existing data acquisition and management processors acquire only a limited range of data types and have small data volumes, and lack real-time data storage capabilities. Utility Model Content

[0003] Purpose of the utility model: To provide a data acquisition and management processor that integrates multiple types of data acquisition and storage, so as to realize the comprehensive and integrated functions of onboard multi-type data acquisition, management, storage, addition / unloading and key destruction, reduce the types and number of airborne products in avionics / mission systems, and further lay the technical foundation for the integrated data management subsystem to play the role of the whole aircraft data management and storage center.

[0004] Technical solution:

[0005] A data acquisition and management processor integrating multiple types of data acquisition and storage includes: a power conversion module, a flight parameter acquisition module, a task processing module, a 1394B bus module, an FC network monitoring module, a video acquisition module, a maintenance data card, and an intelligence data card.

[0006] The power conversion module converts the aircraft's three 28VDC power supplies into +5V, +12V, and -12V power supplies required by each module, providing power to the flight parameter acquisition module, mission processing module, 1394B bus module, FC network monitoring module, video acquisition module, maintenance data card, and intelligence data card. The power failure indicator output of the power conversion module is connected to one I / O port of the mission processing module, and the indicator light input of the power conversion module is connected to another I / O port of the mission processing module.

[0007] The flight parameter acquisition module is used to integrate and package 38 DC / AC analog signals, 100 discrete signals, 4 frequency signals, 32 ARINC429 bus signals, 12 RS422 bus signals and 1 Ethernet video signal, and is connected to one SRIO port of the task processing module via the SRIO bus.

[0008] The 1394B bus monitoring module is used to receive 1394B bus monitoring data from three flight control / electromechanical bus loops. After receiving the data, it is packaged and connected to the three PCIe ports of the task processing module through three independent PCIe buses.

[0009] The FC network monitoring module is used to receive data from four independent FC network monitoring ports on the onboard FC network switch. After receiving the monitoring data, it is packaged and connected to another PCIe port of the task processing module via the PCIe bus.

[0010] The video acquisition module is used to acquire 8 channels of ARINC818 video data. It acquires the raw ARINC818 video data stream output by the relevant devices on the machine, packages it, and connects it to the RapidIO port of the task processing module through the RapidIO bus.

[0011] The maintenance data card is connected to another PCIe bus interface of the task processing module, which is used to store flight parameter data, Ethernet video data, FC network monitoring data and 1394B bus monitoring data sent by the task processing module through the PCIe bus.

[0012] The intelligence data card is connected to the mission processing module via another PCIe bus interface to store intelligence data such as electronic warfare, radar, and surveillance video sent by the mission processing module via PCIe.

[0013] Furthermore, the ARINC429 and RS422 bus signal acquisition circuits in the flight parameter acquisition module are implemented using an "electrical interface device + FPGA" approach, the frequency signal acquisition circuit is implemented using a "conditioning interface circuit + FPGA" approach, the voltage signal acquisition circuit is implemented using an "interface conditioning circuit + multiplex analog switch + programmable amplifier + analog-to-digital converter + FPGA" approach, and the discrete signal acquisition circuit is implemented using an "interface conditioning circuit + multiplex analog switch + voltage follower + analog-to-digital converter + FPGA" approach.

[0014] Furthermore, the task processing module adopts a dual-CPU + FPGA + Ethernet switch + PCIe switch + SRIO switch architecture. CPUA is responsible for the acquisition, organization, packaging, and maintenance of flight parameters, network monitoring, and bus monitoring data, as well as data storage management, task planning data loading, and system status management. CPUB is responsible for the storage and management of massive amounts of intelligence data from surveillance video, radar, and electronic warfare. The FPGA is responsible for logic control, data transmission, and the implementation of external interface logic. The Ethernet switch handles gigabit Ethernet switching, outputting one gigabit Ethernet port and four gigabit Ethernet ports for data interaction with external interconnected devices. The PCIe switch handles high-speed PCIe interface switching, converting the one PCIe x8 port directly output by CPUA into one PCIe x4 port. The SRIO switch handles high-speed SRIO interface switching, providing 14 SRIOX interfaces for internal RapidIO bus networking and data exchange, as well as data interaction with external devices.

[0015] Furthermore, the three 1394B bus monitoring interfaces operate completely independently in terms of power supply and physical operation, without affecting each other. The 1394B bus monitoring module is also restricted from transmitting at the protocol layer to minimize interference from the 1394B bus monitoring module to the onboard flight control / electromechanical 1394B bus link.

[0016] Furthermore, the power conversion module, flight parameter acquisition module, task processing module, 1394B bus module, FC network monitoring module, and video acquisition module are all standard 6U boards.

[0017] Furthermore, apart from storage capacity, the maintenance data card and the intelligence data card have the same physical / functional / performance characteristics.
