A high-speed and reliable remote data acquisition and storage system

Abstract

The invention discloses a high-speed reliable remote data collection storage system, which comprises a data collection module, a network optical fiber module, an optical fiber memory mapped module, a data storage module, a protocol parsing module and a data display module, wherein the protocol parsing module obtains a test instruction by parsing, a main control module controls the data collection module to collect data, the data collection module collects telemetry signals to obtain collection data, the network optical fiber module and the optical fiber memory mapped module receive or read the collection data and transmit, the data storage module stores the collection data, and the data display module displays the collection data. The high-speed reliable remote data collection storage system introduces an optical fiber technology, integrates a memory mapping scheme and a network optical fiber scheme, improves transmission anti-interference ability of the collection data, and reduces transmission fault occurrence frequency of the collection data. Furthermore, the high-speed reliable remote data collection storage system stores the collection data in divided periods during the storage process of data, and further guarantees storage safety and reliability of the data.

Description

technical field [0001] The invention relates to a data acquisition technology in the field test environment of a launch vehicle, in particular to a high-speed and reliable remote data acquisition and storage system. Background technique [0002] With the increasing frequency of space launches, the servo mechanism needs to participate in field test tasks such as power system test run test and thermal test run test for many times. Surface, oil temperature, etc.) for collection, and the collected data is used for real-time display and feedback and subsequent servo system performance analysis. [0003] At present, in most field test environments, the distance between the tower and the controller is hundreds of meters or even thousands of meters. The reliability of the process has higher requirements. The traditional acquisition equipment adopts the method of memory-mapped board, and completes the memory reading and writing work of the upper computer to the lower computer throu...

AI Technical Summary

Problems solved by technology

This method is relatively easy to implement in the programming of the host computer, but it needs to add a relay device every 100 meters on the hardware, which makes the whole system complicated and the reliability becomes difficult to guarantee

At the same time, the traditional remote data acquisition system has large measurement errors, weak anti-interference ability, relatively high frequency of failures and a relatively high probability of abnormalities in the data recording process
