针对船舶气象仪保障维修而设计的船舶气象仪测试系统，包括信息处理终端、主仪器检测模块、传感器检测模块，各个模块都采用基于AVR单片机的嵌入式系统，模块之间通过CAN总线进行通信。结果表明，船舶气象仪测试系统能够快速检测船舶气象仪故障，与单纯依靠人工方式排查故障相比，故障检测时间缩短了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.

为提升虚拟仪器传输速率与实时性能，扩展监测范围，在VC的软件平台上设计了一种全功能虚拟示波器。与传统虚拟示波器相比，该系统采用嵌入式系统完成信号采集，采用工业以太网为传输介质，通过线性插值算法和多线程编程思想，实现波形显示、参数计算、频谱分析以及波形存储及回放功能。实验结果表明，该虚拟示波器可以实现20 kHz采样频率下的波形精确显示，达到预期的各项指标。 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.
