Abstract
In order to solve the problems of low precision in controlling environmental parameters of agricultural greenhouses in different locations and weak remote transmission efficiency,an intelligent remote monitoring system for agricultural greenhouses was developed using technologies such as Ethernet communication,PLC control,frequency conversion speed regulation,and configuration monitoring.The overall scheme,hardware circuit,and software program of the agricultural greenhouse monitoring system based on Ethernet were designed.Experiments have shown that the system not only achieves real-time detection of environmental parameters such as temperature,humidity,and lighting,but also remote detection and precise control of the working status of equipment such as water supply,ventilation,and supplementary lighting.It promotes the high-quality,high-yield,and efficient cultivation of crops in agricultural greenhouses,and realizes real-time data exchange and remote monitoring functions between different greenhouses,providing strong information support and technical support for the intelligent production of agricultural greenhouses.
