Embodiment 1
[0136] The airborne heterogeneous network topology involved in this embodiment is as attached figure 1 As shown, there are three kinds of communication networks between the airborne equipment 1 to the airborne equipment N and the recording equipment, which are respectively FC bus network, 485 bus network and Ethernet network, and the airborne heterogeneous network data recording system proposed by the present invention runs on the on-board recording device.
[0137] The software architecture of the airborne heterogeneous network data recording system is attached figure 2 As shown, it includes the following modules: data acquisition module, data transmission module, and data recording module.
[0138] The data acquisition module includes the FC bus preprocessing module, the 485 bus preprocessing module and the Ethernet preprocessing module. The data acquisition module completes the self-inspection of the CPU, memory and storage card of the device through read and write access...
Embodiment 2
[0164] This embodiment provides an airborne heterogeneous network recording system, and its applicable network includes three kinds of network data channels, namely FC network, 485 bus network and Ethernet.
[0165] The system includes a data acquisition module, a data transmission module and a data recording module.
[0166] The data acquisition module completes the self-inspection of the device CPU, internal memory and memory card through read-write access, completes the inspection of the internal hardware of the device through the power-on self-inspection mechanism, and utilizes the space management when power-on to ensure that each power-on The equipment has enough storage space to store data, collect and quantify the bus data in the heterogeneous network through the data transmission module, and send the preprocessed data to the data recording module through the data transmission module.
[0167] The data transmission module mainly completes network initialization operati...
