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.

NXP Semiconductor designed the LPC2400 MICROcontrolLERs around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 MICROcontrolLERs have 512 kB of on-chip high-speedFlash memory. This Flash memory includes a special 128-bit wide memory interface andaccelerator architecture that enables the CPU to execute sequential instructions fromFlash memory at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM MICROcontrolLER family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two Instruction Sets meansEngineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions in ARM state maximizes core performance.
