摘　　要：测定近海面及地面的气温、湿度和风速梯度,对于研究其间的相互作用是必要的,由于常规气象仪器不满足要求,国内也曾出现了一些梯度记录仪。其中大多不再应用,因为稳定性不够好,操作与资料处理不便。本文的数据采集系统以高性能的传感器和低耗电单片计算机为基础。传感器有良好的稳定性和互抉性。仪器无需常进行标定,输出数据为实际值。显然,它的数据处理是简便的。仪器用干电池供电和固态数据存贮,可以工作在船上、海边和荒野,无需人员值班。当观测结束,仪器可通过 RS-232接口把存贮的数据倒给便携式个人计算机。此系统已实现了全自动的数据采集和处理。它已被用于若干课题,如大气环境评价和海洋大气界面层的研究。It's necessary to measure the profiles of mean air temperature,hu- midity and wind speed close to the earth surface for the study of the interaction between air and the earth.Some gradient recorders had been made in China before because normal meteorologic instruments don't meet the goal.But,the most of them will not be used again because they do not have a good stability,easy operation and easy data proce- ssing。 This paper presents a data collection system based on high perfor- mance sensors and a low power single-chip microcomputer.The sen sors are very stable and exchangeable.The instrument doesn't require users to do re-calibrations and offers data in real value.Sure,its data processing is really easy.The instument uses battery power supply and solid state data storage so that it can work on ships,the coastal and wild areas,also,it does not need people on duty.When a survey is finished,the instrument can duma the stored data into a portable pers- ona computer by a build-in RS-232 standard interface.The system shows a full automatic data collecting and processing already.It has been used in several projects such as atmospheric environmental effect assess- ment and the study of atmospheric boundary layer。
