基于CAN总线技术的温室监控系统的设计

Design of Monitor and Control System on Greenhouse Based on CAN Bus

为了提供作物生长所需要的最佳生态环境,需要对温室环境参数进行实时监控。为此,考虑到CAN总线的主要特点,并从低成本和可靠性以及技术优势的角度出发,提出了基于CAN现场总线的分布式温室监控系统,该系统不仅具有温室环境参数的测控功能,还可以进行集中监控、数据管理等。同时,详细说明了硬件构成及软件设计。

In order to supply the best environment of the plant growing, greenhouse environment parameter is necessary to be supervised. For this reason, considering the main features of CAN bus, from the point of low cost, reliability and technical superiority, the greenhouse control system based on CAN field bus is presented. This system not only has the function of greenhouse environment parameter monitoring, but also has the centralized monitoring, managing data and other function. The composing of hardware and the design of software are described in details.
