摘　　要：传统的城市绿化灌溉水资源浪费严重、人力成本高,为此设计了由PLC、上位机、智能网关和腾讯云组成的绿化灌溉监控系统。PLC控制储水罐,水肥罐向绿植灌溉、施肥,并保持液位稳定。上位机运行监控软件并使用Access数据库保存运行数据便于查询和统计。智能网关连接PLC和腾讯云,利用其内置的Node-RED物联网应用程序使用户通过智能手机实现远程监控,从而进一步解放人力、拓展系统的应用范围。The traditional urban greening irrigation has low efficiency and high labor cost.A greening rrigation monitoring system composed of PLC,upper computer,intelligent gateway,and Tencent Cloud has been designed.PLC controls the water storage tank and water fertilizer tank to irrigate and fertilize green plants and maintain a stable liquid level.The upper com-puter runs monitoring software and uses Access database to save running data for easy query and statistics.The intelligent gateway connects PLC and Tencent Cloud,utilizing its built-in Node-RED IoT application to enable users to remotely moni-tor through smartphones,thereby further liberating manpower and expanding the application scope of the system.
