Embodiment

[0046] The present invention will be described in detail below with a specific embodiment.

[0047] Such as image 3 As shown, the storage area in this embodiment is divided into 256 segments, and each segment is 255 bytes. The description is based on the telemetry frame. A full frame is stored in 85 bytes, and 3 full frames are stored in one segment.

[0048] Such as Figure 4 As shown, the write control module in a kind of high-speed aircraft black obstacle area data measurement processor of the present embodiment comprises the first D flip-flop I78, the second D flip-flop I79, the third D flip-flop I77, and gate I82, or Gate I81, the first NOT gate I85, the second NOT gate I84, the first counter I61, the second counter I59 and the third counter I75;

[0049]The full frame identification signal SS and the write clock signal BS are respectively connected to the data end and the clock end of the first D flip-flop I78, and the output end of the first D flip-flop I78 is connec...

Abstract

The present invention provides a kind of high-speed aircraft black obstacle area data measurement processing method and processor, described method is: (1), will receive parameter data and be divided into 2 N parameter data segments, N is greater than or equal to 1; (2), in the high-speed aircraft re-entry section black barrier area, take the segment as the unit, count the parameter data segment value 0~2 N ‑1 corresponds to the binary representation D 0 ~D N The 0th to the N-1th bit of the segment address, as the N-1st to the 0th bit of the segment address, stores the parameter data segment; (3), in the low-altitude electric wave transmission recovery area, the segment is used as the unit, according to 0 ~2 N The sequence of ‑1 reads and retransmits the parameter data segments continuously. The valid data read by the present invention gradually become complete with the increase of the retransmission time until all the measured data are read and restored to complete.

Description

technical field [0001] The invention relates to a method and a processor for measuring and processing data in a blackout area of ​​a high-speed aircraft, belonging to the technical field of data processing. Background technique [0002] The aircraft that need to return all have data measurement problems in the blackout area of ​​the re-entry section. At present, the data can be stored in the black box, and it can be completed in the form of finding the black box after the flight mission is completed. The advantage of the black box is that it stores a large amount of data. The disadvantage is that the stored data cannot be transmitted wirelessly in real time. It requires separate equipment and strict environmental assessments, which greatly increases the mission cost. Moreover, the black box may not be recovered smoothly due to the impact of the environment and flight trajectory. . Contents of the invention [0003] The technical solution problem of the present invention ...
