摘　　要：农业生产技术的快速发展,迫切需要一种适用于普及的、可靠、有效的针对农田小气候信息参数的实时采集系统,提高人们对作物生长与小气候之间关系的认识,为农业生产服务。本文介绍了基于PIC单片机的小气候信息采集系统便携机部分设计,文中详细描述了小气候信息采集方法和系统软硬件结构。便携机系统实现了包括温湿度、光照度、降雨量、蒸发量、大气压等15种小气候参数的自动、实时监测。通过实践证明该便携机设计合理、性能可靠,作为小气候信息采集系统的主体部分,是适合目前农田小气候信息自动监测的普及型设备。With the rapid development of agriculture production technology, it is in urgent need of a general, reliable, effective and real-time acquisition system for farmland microclimate parameters. It will improve cognition of the relationship between the crop growth and the microclimate, and service the agriculture production as well. This paper mainly introduced the protable equipment of microclimate information acquisition system based on microcomputer and made a detailed description on data acquisition methods and system’s software and hardware structure. It can real-time monitor 15 kinds of parameters automatically, including temperature, humidity, light intensity, rainfall, evaporation, atmospheric pressure, etc. The practice proved that the protable equipment is possessed of reasonable design and reliable performance. As the main part of microclimate information acquisition system, it will be a general machine suitable for automatic monitoring of farmland microclimate parameters.
