針對船舶氣象儀保障維修而設(shè)計的船舶氣象儀測試系統(tǒng)，包括信息處理終端、主儀器檢測模塊、傳感器檢測模塊，各個模塊都采用基于AVR單片機的嵌入式系統(tǒng)，模塊之間通過CAN總線進行通信。結(jié)果表明，船舶氣象儀測試系統(tǒng)能夠快速檢測船舶氣象儀故障，與單純依靠人工方式排查故障相比，故障檢測時間縮短了60%以上。 Abstract: The test system of ship meteorological instrument was developed to satisfy the maintenance of ship meteorological instruments，which composed of information processing terminal， testing module of main instrument and testing module of sensors. Each of these modules included an embedded system based on microcontroller of AVR series and communicated with other module by CAN bus. The results show that the test system can judge the fault of ship meteorological instrument quickly and shorten the fault detection time as much as 60% compared with simple manual troubleshooting.

The TRS232E is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/RS-232-Fvoltage levels from a single 5-V supply. Each receiver converts TIA/RS-232-F inputs to 5-V TTL/CMOS levels.This receiver has a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs. Eachdriver converts TTL/CMOS input levels into TIA/RS-232-F levels. The driver, receiver, and voltage-generatorfunctions are available as cells in the Texas Instruments LinASIC™ library.

為提升虛擬儀器傳輸速率與實時性能，擴展監(jiān)測范圍，在VC的軟件平臺上設(shè)計了一種全功能虛擬示波器。與傳統(tǒng)虛擬示波器相比，該系統(tǒng)采用嵌入式系統(tǒng)完成信號采集，采用工業(yè)以太網(wǎng)為傳輸介質(zhì)，通過線性插值算法和多線程編程思想，實現(xiàn)波形顯示、參數(shù)計算、頻譜分析以及波形存儲及回放功能。實驗結(jié)果表明，該虛擬示波器可以實現(xiàn)20 kHz采樣頻率下的波形精確顯示，達(dá)到預(yù)期的各項指標(biāo)。 Abstract: o enhance the transfer rate and real-time of virtual instrument performance， expand scope of monitoring， this paper uses the VCs software platform to design a fully functional virtual oscilloscope. Compared with traditional virtual oscilloscope， this system adopts the embedded system to complete the data acquisition， industrial Ethernet as the transmission medium used by the linear interpolation algorithm and multi-threaded programming ideas， namely to achieve waveform display， parameter calculation， spectrum analysis and waveform storage and playback. Experimental results show that the virtual oscilloscope can accurately display the waveform with 20kHz sampling frequency， and achieve the desired targets.
