摘　　要：为了长时间、连续地全程记录运输过程中的三向加速度和温湿度数据,采用MEMS加速度传感器和温湿度传感器、实时时钟、低功耗32位微处理器、SD卡、模块化的碱性电池组等构建运输环境监测仪,睡眠-唤醒巡检的工作方式和上位机在SD上建立文件系统、监测仪直接访问SD卡数据块的数据存储机制有效降低了功耗,频响特性测试、功耗测试、低温运行和搭载测试试验表明该运输环境监测仪满足使用需求。In order to continually record the three axis acceleration and temperature and humidity data for a long time,a transportation environment monitor is introduced which is based on MEMS acceleration sensor and temperature humidity sensors,real-time clock,low power 32-bit microprocessor,SD card,modular alkalescency batteries and so on.Its sleep/wake-up operation mode,and data storage mechanism that the file system of SD card is established by computer and the monitor directly access its data block,efficiently reduce its power.Frequency response test,power consumption test,low temperature operation and on-board test indicate that the transportation environment monitor satisfies the requirements.
