??? 關鍵詞： PCI 總線；天氣雷達,；數(shù)據(jù)采集,；Linux平臺

?

??? Linux是開放源代碼、網(wǎng)絡化的操作系統(tǒng),，具有穩(wěn)定,、高效、內(nèi)核可自由配置等特點,。采用Linux 操作系統(tǒng)作為開發(fā)平臺與采用VxWorks 和Windows 作為開發(fā)平臺相比不僅有免費的優(yōu)勢,，而且對于發(fā)展核心技術，提高信息安全有著極其重要的意義,，是自主研發(fā)的一個方向,。隨著我國天氣雷達的快速發(fā)展，天氣雷達在民用和軍事領域的應用越來越廣泛,。目前,，天氣雷達高速數(shù)據(jù)采集、傳輸?shù)裙δ艽蠖蓟赪indows平臺進行開發(fā)實現(xiàn),，實現(xiàn)由Windows平臺向Linux平臺的轉換,，對于發(fā)展中國自主知識產(chǎn)權氣象軟件核心技術, 提高信息安全有著極其重要的意義。本文基于Linux 操作系統(tǒng)(2.6.23內(nèi)核)，實現(xiàn)了天氣雷達高速數(shù)據(jù)采集及處理,，對天氣雷達系統(tǒng)由Windows平臺向Linux平臺移植具有參考價值,。?

1 數(shù)據(jù)采集系統(tǒng)分析?

1.1 工作原理?

??? 天氣雷達高速數(shù)據(jù)采集系統(tǒng)由I/Q數(shù)據(jù)采集、FIFO緩沖,、FPGA控制模塊及PCI總線芯片PLX9054組成,，系統(tǒng)結構框圖如圖1所示。?

?

?

??? 其核心部分為FPGA控制模塊,，主要實現(xiàn)4個功能:(1)根據(jù)雷達量程和距離分辨率調(diào)整AD采樣時鐘的頻率,；(2)控制AD兩路采樣數(shù)據(jù)寫入FIFO 緩沖以及DMA 傳輸時從FIFO中連續(xù)讀出數(shù)據(jù)； (3)與PCI總線控制芯片PLX9054 進行控制交互, 實現(xiàn)局部總線的讀寫控制,、地址譯碼和中斷觸發(fā),；(4)與PLX9054 進行數(shù)據(jù)交互，使用FPGA內(nèi)部RAM保存控制天氣雷達發(fā)射機和接收機工作的命令及數(shù)據(jù),，完成對雷達工作的控制,。?

??? I/Q數(shù)據(jù)采集輸出數(shù)據(jù)速度為2.4 Mb/s(I、Q數(shù)據(jù)各為24 bit),，通過FPGA控制,，合并寫入到FIFO緩沖。FIFO緩沖為32 bit,、深度為16 KB的數(shù)據(jù)緩存,，有效位為24 bit；與計算機總線的接口采用32 bit的PCI總線接口芯片PLX9054,，PC機通過它完成與數(shù)據(jù)采集系統(tǒng)的數(shù)據(jù)交互,。?

1.2 PC機與采集系統(tǒng)數(shù)據(jù)訪問?

1.2.1 局部地址分配?

??? PC機與天氣雷達高速數(shù)據(jù)采集系統(tǒng)的數(shù)據(jù)訪問通過PCI總線芯片PLX9054實現(xiàn)，訪問目標為FIFO緩沖和FPGA片內(nèi)RAM,。對FIFO緩沖和FPGA片內(nèi)RAM分配不同局部地址,，通過對局部地址總線進行譯碼確定需要訪問的目標。FIFO 數(shù)據(jù)采用DMA傳輸方式連續(xù)讀出, 每次傳輸長度最大為8 KB,因此,設置FIFO空間32 bit局部地址范圍為0x20000000～0x2000FFFF,，映射空間為PCI 地址空間bar2,。?

??? FPGA片內(nèi)RAM位寬為32 bit, 采用局部地址范圍為0x40000000～0x400FFFFF。映射空間為PCI地址空間bar3,。?

1.2.2 數(shù)據(jù)訪問方式?

??? FIFO緩沖為可編程FIFO,，由FPGA根據(jù)片內(nèi)存儲的雷達參數(shù)進行控制。當FIFO中數(shù)據(jù)達到設置的大小時,，觸發(fā)PCIPLX9054引發(fā)PCI中斷,，通過該中斷向驅動程序申請發(fā)起DMA 傳輸。驅動程序響應該中斷后設置PCIPLX9054的DMA寄存器, 發(fā)起方向從局部總線到PCI總線的DMA傳輸,，完成FIFO數(shù)據(jù)向PC機的傳輸,。?

??? FPGA片內(nèi)RAM通過PCI地址映射,，使用IO操作方式進行數(shù)據(jù)讀寫訪問。?

2 Linux程序實現(xiàn)?

??? 天氣雷達高速數(shù)據(jù)采集系統(tǒng)基于Linux2.6內(nèi)核平臺程序,，由基于PCI總線的設備驅動程序,、數(shù)據(jù)采集及處理程序組成。?

2.1 設備驅動程序實現(xiàn)?

??? 設備驅動程序的功能是在Linux2.6系統(tǒng)平臺下,，通過對PCI總線控制芯片PLX9054的控制,實現(xiàn)PC機與采集板的數(shù)據(jù)交互,，實現(xiàn)雷達采集數(shù)據(jù)的實時接收及雷達工作狀態(tài)的控制。從功能結構上,，設備驅動主要由設備裝載及初始化,、提供給用戶層的接口函數(shù),、中斷及DMA數(shù)據(jù)傳輸三部分組成,。?

2.1.1 設備裝載及卸載?

??? 設備裝載和卸載即是Windows系統(tǒng)中設備驅動安裝和卸載。在Linux2.6中,，裝載和卸載主要通過調(diào)用系統(tǒng)提供的PCI總線驅動注冊函數(shù)pci_register_drive和注銷函數(shù)pci_unregister_driver來實現(xiàn),，其注冊的driver數(shù)據(jù)結構如下：?

??? static struct pci_driver? plx9054_pci_driver = {?

??? ???? .name? = 'pci9054',?

??? ???? .id_table? = plx9054_pci_tbl,?

??? ???? .probe = plx9054_probe,?

??? ???? .remove??? = plx9054_remove,?

??? ???? };?

??? 當系統(tǒng)引導時，高速數(shù)據(jù)采集系統(tǒng)板上電后,，板上PCI總線固件對PLX9054設備進行缺省配置,，為設備的每個地址區(qū)域分配好資源。裝載函數(shù)在驅動中用module_init聲明,，進行設備的初始化工作,，調(diào)用PCI總線驅動注冊函數(shù)，根據(jù)id_table定義的信息對PCI設備PLX9054進行探測識別,，完成PLX9054設備驅動的PCI總線注冊,然后調(diào)用驅動注冊的probe函數(shù),，完成PLX9054設備使能、PCI地址空間映射,、PLX9054設備數(shù)據(jù)結構初始化,、設備注冊(注冊為字符設備)等操作。卸載函數(shù)用module_exit聲明,，是裝載的逆過程,，通過調(diào)用PCI總線驅動卸載函數(shù)，繼而調(diào)用注冊的remove函數(shù),、注銷設備及PCI地址空間映射,、釋放分配給設備的數(shù)據(jù)結構空間等操作，完成系統(tǒng)資源釋放,。?

2.1.2 設備接口函數(shù)?

??? 設備接口函數(shù)為用戶提供與設備進行交互的不同功能接口,，主要完成用戶與設備的讀、寫及設備控制訪問等功能,，其數(shù)據(jù)結構設計為：?

??? static const struct file_operations plx9054_fops = {?

??? ???? .owner = THIS_MODULE,?

??? ???? .open????? = plx9054_open,? /*打開設備*/?

??? ???? .release?? = plx9054_close,? /*釋放設備*/?

??? ???? .ioctl???? = plx9054_ioctl,? /*IO操作*/?

??? ???? .read????? = plx9054_read,? /*讀設備*/?

??? ???? };?

??? 這個數(shù)據(jù)結構在設備裝載過程中,，作為設備注冊的參數(shù)完成與設備掛接,、使用戶在系統(tǒng)調(diào)用中能訪問到上述關聯(lián)的設備接口函數(shù)。?

??? 設備打開函數(shù)plx9054_open完成以下操作：設備私有數(shù)據(jù)結構內(nèi)存空間分配及初始化,，DMA連續(xù)物理內(nèi)存空間申請,，為天氣雷達最大距離探測采集數(shù)據(jù)的大小,；調(diào)用pci_map_single將分配的DMA內(nèi)存空間映射為用于DMA傳輸?shù)刂?；DMA數(shù)據(jù)緩沖區(qū)分配(容量為2 MB)，緩沖區(qū)保存每次DMA傳輸中獲取的數(shù)據(jù),；調(diào)用request_irq對中斷函數(shù)p9054_interrupt進行中斷號申請,；對天氣雷達工作參數(shù)進行缺省配置，啟動雷達工作,。設備釋放函數(shù)PLX9054_close完成的操作與設備打開函數(shù)與PLX9054_open相反,。IO操作函數(shù)PLX9054_ioctl通過sys_ioctl系統(tǒng)調(diào)用，完成用戶與設備的信息查詢,、雷達工作參數(shù)配置與查詢,，如驅動軟件版本號、雷達當前工作各參數(shù)配置和查詢,，主要用于對FPGA中RAM內(nèi)存空間的雷達工作參數(shù)數(shù)據(jù)訪問,。由于這部分數(shù)據(jù)對訪問速度要求不高，使用IO操作能很好地滿足設計要求,。讀設備函數(shù)PLX9054_read將驅動DMA數(shù)據(jù)緩沖區(qū)中的數(shù)據(jù)實時讀取到用戶空間緩沖區(qū)內(nèi),，完成采集數(shù)據(jù)從設備到用戶的讀取操作。?

2.1.3 中斷處理及DMA傳輸?

??? 中斷處理及DMA傳輸是驅動的核心部分,，它的設計質(zhì)量直接影響到雷達采集數(shù)據(jù)能否正確,、實時地從采集系統(tǒng)板傳送到設備驅動緩沖區(qū)，并實時被用戶獲取,。中斷處理工作流程如圖2所示,。?

?

?

??? 由于DMA數(shù)據(jù)緩沖區(qū)遠大于每次DMA數(shù)據(jù)傳輸大小，這對于雷達數(shù)據(jù)采集中因用戶讀取數(shù)據(jù)延遲而導致的緩沖區(qū)溢出有較好的抑制作用,，而相對于現(xiàn)有計算機平臺,，2 MB內(nèi)存容量已足夠。DMA數(shù)據(jù)緩沖區(qū)設計為循環(huán)緩沖區(qū),，使用讀,、寫指針維護，在中斷處理中更新其寫指針,，在PLX9054_read中更新其讀指針,，采用溢出則覆蓋的機制，既方便管理,，節(jié)省資源,，同時又可對溢出進行計數(shù),，很方便進行實時性能的測試。?

2.2 數(shù)據(jù)采集處理程序實現(xiàn)?

??? 數(shù)據(jù)采集處理程序是雷達高速數(shù)據(jù)采集系統(tǒng)的應用處理程序,，完成雷達高速數(shù)據(jù)采集及對采集數(shù)據(jù)的數(shù)字信號處理,、輸出天氣雷達生成一次產(chǎn)品。其主要流程如圖3所示,。?

?

?

??? 在采集I/Q數(shù)據(jù)時,，I/Q兩路數(shù)據(jù)采用交叉采集方式存入FIFO緩沖中，每路數(shù)據(jù)有效位為23,，最高位為符號位,。因此，在采集數(shù)據(jù)處理中需對讀取的數(shù)據(jù)進行I/Q數(shù)據(jù)分離,，即將采集數(shù)據(jù)恢復為原始I,、Q兩路數(shù)據(jù)，同時將24 bit數(shù)據(jù)轉換為32 bit數(shù)據(jù)方式存儲,，以滿足后面數(shù)字信號處理要求,。?

??? 在軟件設計中,，不同數(shù)字信號處理功能采用不同數(shù)字信號處理函數(shù)實現(xiàn),，在采集數(shù)據(jù)獲取前進行選擇配置，數(shù)字信號處理功能增加可通過增加相關的數(shù)字信號處理函數(shù)來滿足,，以方便功能的完善和移植,。通過對I/Q數(shù)據(jù)分離后獲得的數(shù)據(jù)進行相關數(shù)字信號處理即可獲得天氣雷達中的一次產(chǎn)品，如功率和反射率等,。?

??? 本文基于Linux2.6平臺,，設計實現(xiàn)了天氣雷達高速數(shù)據(jù)采集系統(tǒng)的驅動和數(shù)據(jù)采集及對采集數(shù)據(jù)的數(shù)字信號處理，并在現(xiàn)有天氣雷達上完成了調(diào)試驗證,。目前,，本設計已成功地應用在現(xiàn)有的天氣雷達中。?
