【摘要】：目前地面的自動(dòng)檢測(cè)裝置被廣泛應(yīng)用在航空航天事業(yè)中，在飛行器發(fā)射過(guò)程中，數(shù)據(jù)存儲(chǔ)器負(fù)責(zé)存儲(chǔ)飛行器上各類傳感器所產(chǎn)生的參數(shù)信息，而地面的檢測(cè)裝置對(duì)測(cè)試存儲(chǔ)器的各種性能參數(shù)起到了至關(guān)重要的作用，因此，自動(dòng)檢測(cè)裝置的研制對(duì)于航天事業(yè)來(lái)說(shuō)是一個(gè)大的突破。 本文所設(shè)計(jì)的地面綜合檢測(cè)設(shè)備主要是針對(duì)飛行器上數(shù)據(jù)存儲(chǔ)器而言的，在對(duì)存儲(chǔ)器進(jìn)行實(shí)際應(yīng)用前，需要對(duì)存儲(chǔ)器進(jìn)行大量實(shí)驗(yàn)，以確保存儲(chǔ)器的各項(xiàng)性能指標(biāo)都滿足要求。在單元檢測(cè)時(shí)，遙測(cè)控制臺(tái)需要向存儲(chǔ)器提供一路信號(hào)源，同時(shí)還需要向存儲(chǔ)器發(fā)送各種指令信號(hào)，方便對(duì)存儲(chǔ)器進(jìn)行各種測(cè)試。通過(guò)對(duì)數(shù)據(jù)傳輸特點(diǎn)進(jìn)行分析，本文選用RS-422異步串行的方式對(duì)數(shù)據(jù)進(jìn)行近距離傳輸，選用光纖實(shí)現(xiàn)本文的5KM距離的遠(yuǎn)程傳輸。 本論文設(shè)計(jì)了備用口讀數(shù)模塊，，主要是針對(duì)飛行器發(fā)射后，利用此備用口對(duì)存儲(chǔ)器殘骸進(jìn)行讀數(shù)。以往的檢測(cè)裝置都是測(cè)試臺(tái)和工控機(jī)單獨(dú)放置，在測(cè)試現(xiàn)場(chǎng)不便移動(dòng)；本文中將鍵盤鼠標(biāo)、工控機(jī)、遙測(cè)控制臺(tái)和電源箱都統(tǒng)一的放置在機(jī)柜中，提高了檢測(cè)裝置的便易性。 通過(guò)后期大量的實(shí)驗(yàn)證明，本文所設(shè)計(jì)的檢測(cè)設(shè)備性能穩(wěn)定，能夠可靠的完成對(duì)數(shù)據(jù)存儲(chǔ)器的測(cè)試工作，并能夠可靠對(duì)數(shù)據(jù)進(jìn)行回讀，通過(guò)上位機(jī)對(duì)這些數(shù)據(jù)進(jìn)行處理和分析，對(duì)研究人員有很大的參考價(jià)值。
[Abstract]:The ground automatic detection device is widely used in the aerospace industry, the aircraft launch process, parameter information generated by all kinds of sensor data memory for storage on the aircraft, and the various performance parameters of the ground testing device of testing memory plays a crucial role in the development of the automatic detection device is a a major breakthrough for the aerospace industry.
Ground testing equipment designed in this paper is mainly on the aircraft data memory, in the practical application of memory, the need for a large number of experiments on the memory, in order to ensure the performance indicators meet the requirements. In the memory unit detection, remote sensing provides a signal source console to the memory, but also need to send a command signal to the memory, facilitate various tests of memory. Through analyzing the data transmission characteristics analysis, this paper chooses RS-422 asynchronous serial way of data transmission distance, the selection of optical fiber to realize the remote transmission distance of 5KM.
This thesis designs the spare port reading module, mainly for aircraft after the launch, the export of spare memory debris readings. The former detecting devices are tested and IPC separately placed in the test site, the inconvenience of moving; this paper keyboard and mouse, IPC, remote console and power box are placed in uniform in the cabinet, improve the detection device is easy.
The experiments show that the detection performance of equipment designed in this paper is stable, can complete the testing of reliable data storage, and the data can be reliably read back, processing and analysis of these data by computer, has great reference value for the researchers.
