温室环境多点数据嵌入式智能监测系统

The Embedded Monitoring System for Greenhouse Environmental Multi-points Information Collecting

应用温室技术进行农作物种植是实现我国农业现代化过程中的重要环节,温度和湿度是温室控制中的重要环境参数。为实现对多点温湿度数据的自动监测,设计了以32位ARM处理器S3C44B0X为核心的多路数据采集和处理系统。该系统采用单一采集中心和多个智能采集节点的分布式结构,节点与中心采用RS-485总线进行通信,采集中心实时地收集、处理和显示各智能节点传回的温湿度数据,可有效提高数据采集工作的效率和稳定性。

The application of greenhouse technology is important to Chinese agricultural modernization. Temperature and humidity are important factors of greenhouse control. A multi-points data collecting and processing system was designed to automatically monitor temperature and humidity. A distributed construction was adopted in this system,which included one collecting center and multi intelligent collecting points. RS-485 was the communication standard in this system. Temperature and humidity data were collected,processed and displayed by the real-time collecting center,which could ameliorate the efficiency and stabilization.
