摘要: 针对物联网架构下农业大棚群环境参数监测与预警系统的需求,设计一款农业物联网感知层设备——感控终端。该设计选用C8051F020作为微处理器,通过SI4464实现无线数据通信,利用ULN2022驱动继电器,实现接入设备的控制。而且,提出“轻量级”数据融合算法,用于感知数据“保真”预处理。目前,该设备已在水稻育种大棚安装使用。现场测试情况显示,本设备能够准确感知各类环境参数,设备的自动和手动控制稳定可靠,对于设备在运行过程中出现的异常情况能准确判断并做相应处理。

Abstract: In view of the needs of environmental monitoring and prediction system for greenhouse group in IOT framework, an  agriculture sensing-controlled device based on IOT is designed. The C8051F020 is used as the MCU and the SI4464 as RFIC. The controlling of connected devices is achieved by ULN2022 driven relays. And a tiny data fusion algorithm is proposed, it is designed to improve the accuracy of data. Up to now, the device  has been used in rice breeding greenhouses. The scene test shows that the device can sense different types of environmental parameters accurately, auto-operation and manual-operation are stable and reliable. Unusual conditions relating to the manufacturing can be judged and processed accurately.

Key words: sensing-controlled device; internet of things, environmental parameters; data fusion
