摘要
随着近年来自动控制水平的提高,先进的控制技术也被应用于智能温室。国内外大多数的智能温室系统产品,都存在着造价过高、系统复杂、难于普及等问题。我国欠发达地区较多,气候条件也千差万别,因而需要开发出适合于国情的且低成本的经济型智能温室系统。本文采用价格低廉的51系列单片机为控制器,普通PC作为监控中心,网络通信采用MODBUS总线协议,配以各种传感器及执行机构,构成了一个经济实用的温室控制系统。该系统可根据工程实际与控制系统规模的大小加以配置,对于现有温室的改造及智能型温室的普及有一定的工程实用价值。
In recent years, with the level of automation raising, advanced control techniques are utilized for intelligent greenhouse. Most of the greenhouses in our country and abroad there is a Problem is products high cost, system complexity, difficult to be applied generally. There are many less developed areas in China. climate conditions are also not the same, so need to design the appropriate to national circumstances, low-cost intelligent greenhouse system. So that ordinary users can experience the convenience brought by technology. In this paper, With inexpensive 51 series MCU as the controller, An ordinary PC as control center, Network communication using MODBUS bus protocol. With a variety of sensors and actuators to form an economic and practical greenhouse control system. The size of the control system can according to the engineering practice. There is a certain reference value for the transformation of the existing greenhouse and the popularity of intelligent greenhouse.
