【摘要】：自主管理器作為深空探測(cè)器的核心系統(tǒng),主要實(shí)現(xiàn)了整個(gè)探測(cè)器的任務(wù)規(guī)劃、調(diào)度和數(shù)據(jù)管理,其在軌運(yùn)行的可靠性決定了整個(gè)深空探測(cè)任務(wù)的成敗。為保障自主管理器的可靠性,在自主管理器研制過(guò)程中需要對(duì)其進(jìn)行全面的測(cè)試與驗(yàn)證。本文研制的深空探測(cè)自主管理器地面測(cè)試系統(tǒng)為實(shí)現(xiàn)自主管理器PCM遙控功能、BPSK遙測(cè)功能、數(shù)傳基帶數(shù)據(jù)傳輸功能和載荷數(shù)據(jù)管理功能的測(cè)試提供了保障。本文首先分析了自主管理器的實(shí)際測(cè)試需求,并考慮地面測(cè)試系統(tǒng)的擴(kuò)展性,確定了PXIPXIe的設(shè)計(jì)架構(gòu),根據(jù)設(shè)計(jì)要求中的接口類(lèi)型和功能,將測(cè)試系統(tǒng)劃分為遙控和數(shù)傳模塊、BPSK遙測(cè)模塊和載荷數(shù)據(jù)模擬模塊。其中,遙控和數(shù)傳模塊采用SRAM乒乓緩存技術(shù)實(shí)現(xiàn)了數(shù)傳數(shù)據(jù)的緩存,使用PCI 9054接口芯片實(shí)現(xiàn)了PXI總線(xiàn)高速數(shù)據(jù)傳輸;BPSK遙測(cè)模塊為Flex RIO可重構(gòu)儀器模塊,通過(guò)在Lab VIEW軟件中實(shí)現(xiàn)了基于Costas環(huán)的BPSK信號(hào)載波同步以及基于Gardner算法的位定時(shí)同步,并利用Flex RIO的FPGA重構(gòu)技術(shù)在該模塊上實(shí)現(xiàn)了上述兩種環(huán)路,完成了BPSK遙測(cè)信號(hào)的數(shù)字解調(diào)和接收;載荷數(shù)據(jù)模擬模塊采用4片8GB容量的CF卡實(shí)現(xiàn)了大容量載荷數(shù)據(jù)的存儲(chǔ),采用基于Avalon總線(xiàn)的PCI接口技術(shù)實(shí)現(xiàn)了載荷數(shù)據(jù)的DMA突發(fā)加載。然后利用NI VISA為各硬件模塊開(kāi)發(fā)了Windows 7系統(tǒng)下的PXI驅(qū)動(dòng)。最后在Lab VIEW中基于生產(chǎn)者-消費(fèi)者架構(gòu)編寫(xiě)了上位機(jī)控制軟件,同時(shí)在軟件中實(shí)現(xiàn)了符合CCSDS 131.0-B-2規(guī)范的RS級(jí)聯(lián)卷積解碼。測(cè)試與驗(yàn)證結(jié)果表明地面測(cè)試系統(tǒng)能夠很好的滿(mǎn)足自主管理器PCM遙控、BPSK遙測(cè)、數(shù)傳基帶數(shù)據(jù)傳輸和載荷數(shù)據(jù)管理功能的測(cè)試需求,且該地面測(cè)試系統(tǒng)具有較好的通用性與擴(kuò)展性。本文研制的地面測(cè)試系統(tǒng)已經(jīng)成功運(yùn)用于某深空探測(cè)自主管理器的對(duì)接調(diào)試和測(cè)試中。
[Abstract]:Independent management as the core system of deep space probe, mainly realizes the whole spacecraft mission planning, scheduling and data management, its orbit reliability determines the deep space exploration mission success. For ensuring reliability of autonomic manager, in the process of development of independent management is the need for testing and verification of its comprehensive. The deep space Autonomous management of ground testing system developed in this paper for the realization of independent manager PCM BPSK remote control, telemetry, digital baseband data transmission function and load data management function test to provide a guarantee. This paper first analyzes the actual needs of independent test manager, and consider the scalability of the ground testing system. The design of PXIPXIe architecture, interface types and functions according to design requirements, the test system is divided into remote control and data transmission module, BPSK module and load telemetry The data simulation module. The remote control and data transmission module to realize the data transmission of data cache using SRAM ping-pong cache technology, using PCI 9054 interface chip to achieve high-speed data transmission of PXI bus; BPSK telemetry module reconfigurable instrument module for Flex RIO, through the Lab VIEW software is based on BPSK signal carrier synchronization loop Costas and based on a timing synchronization algorithm of Gardner, and the module realizes the two loop using FPGA Flex RIO reconstruction technology, complete digital demodulation of BPSK telemetry signal and receiving data; load simulation module with 4 8GB capacity CF card to achieve a large capacity data storage load, using PCI interface technology Avalon bus realizes sudden load data based on DMA. Then using NI VISA as the hardware module Windows 7 system under the PXI driver. The last Lab in VIEW based on production The consumer - architecture of PC control software, at the same time in the software to achieve the RS decoding CCSDS 131.0-B-2 concatenated convolutional codes. Test and verification results show that the ground test system can well meet the independent manager PCM BPSK remote control, telemetry, test requirement digital baseband data transmission and load data management function, and the ground test system has good versatility and expansibility. The ground test system developed in this paper has been successfully applied to a deep space autonomous docking manager debugging and testing.
