基于单片机技术的温室温度测控系统的设计

Design of Greenhouse Temperature Measurement and Control System Based on Singlechip Technology

温度控制是温室大棚需要解决的重要问题之一。以51单片机为核心控制器,利用数字温度传感器和RS-485总线,构造一套结构简单、运行可靠以及造价低的温度控制网络。系统采用传感器分布式布局,应用集中式采集与管理的结构,提升了温度控制精度。系统实现简便,建设成本低,具有一定的工程实用价值。

Temperature control is one of the important problems to be solved in greenhouse.In this paper,51 single-chip microcomputer is used as the core controller,using digital temperature sensor and RS-485 bus,a set of temperature control network with simple structure,reliable operation and low cost is constructed.The system adopts the structure of distributed sensor layout and centralized collection and management,which improves the precision of temperature control,and the system is easy to realize and low in construction cost.
