摘要
以农业大棚作物温湿度需求为研究对象,对土壤含水率、光照强度及农业大棚室内温度进行实时监测,通过灌溉方式、遮阳策略和通风策略保证作物温湿度需求。采用可编程控制器(PLC)建立温湿度控制系统,分区进行土壤的湿度、光照强度及室内温度信息采集,采用上位计算机对数据进行分析处理,按照控制程序生成指令;也可以通过上位机查看农业大棚温湿度情况,同时通过自动或手动调节农业大棚温湿度。经试验验证,该系统有较高的可靠性,可以在农业大棚中广泛应用。
Taking the temperature and humidity demand of crops in agricultural glasshouses as the research object,real-time monitoring of soil water content,light intensity and indoor temperature of agricultural glasshouses is conducted to ensure the temperature and humidity demand of crops through irrigation method,shading strategy and ventilation strategy.The programmable controller(PLC)is used to set up the temperature and humidity control system,which is divided into soil moisture,light intensity and indoor temperature information acquisition,using the upper computer to analyse and process the data,and generate commands according to the control program.It is also possible to view the temperature and humidity situation of the agricultural greenhouse through the upper computer and at the same time adjust the temperature and humidity in the agricultural greenhouse by automatic or manual adjustment.
