On-chip network form storage system and on-chip network form storage method based on linear optical fiber token bus

Abstract

The invention provides an on-chip network form storage system and an on-chip network form storage method based on a linear optical fiber token bus, which are used for storing parameter information ofeach part of an aircraft, and the storage system comprises two or more data acquisition and editing devices, optical fiber token buses and an on-chip network-based form scattered storage server; eachacquisition and editing device is provided with two buffer areas, each buffer area is connected with one photoelectric conversion interface, and the optical fiber token buses A and B form two independent redundant double-bus structures, so that the reliability and the high efficiency of the collecting system are improved; an interface of the collecting and editing device is only used for sending state information; an interface of the storage server obtains bus control right in turn, schedules data transmission of the acquisition and editing device and stores the data in the storage server, sothat a form scattered storage unit space division multiplexing technology, multi-node collecting and encoding and centralized storage are realized, and the purposes of clock unification of the collecting and editing device, efficient utilization of cabin space and reduction of black box recycling time are achieved.

Description

technical field [0001] The invention relates to an on-chip network form storage system and method based on a linear optical fiber token bus, and belongs to the technical field of aerospace testing. Background technique [0002] The data black box is the only means of testing the system when the spacecraft is in the launch tube, underwater or returning to the "black zone" of the atmosphere. With the continuous development of aerospace test technology, the requirements for the types and quantities of data black boxes in the test system are gradually increasing. If the tail cover of the aircraft, the booster, the first-level cabin, the second-level cabin, the head, etc. all need data black boxes to record various flight parameters, the current solution is only in each required cabin or position. Corresponding data black boxes are placed separately, and these black boxes do not have any electrical and communication connections with each other. As a result, the clocks of each da...

AI Technical Summary

Problems solved by technology

If the tail cover of the aircraft, the booster, the first-level cabin, the second-level cabin, the head, etc. all need data black boxes to record various flight parameters, the current solution is only in each required cabin or position. Corresponding data black boxes are placed separately, and these black boxes do not have any electrical and communication connections with each other. As a result, the clocks of each data black box cannot be accurately unified, and the field test data black box has a large number of instruments and cables, which reduces the reliability of the test. , The cost increases, and most of the cabins are limited in size, and the space planning is difficult. Each cabin that needs to be tested needs to reserve enough space to install the black box and its recovery protection device, which reduces the space utilization of the cabin and cannot fully adapt Demand and Development of Aerospace Telemetry Technology
