In terms of the water resources control in water flow standard device, the communication tween Kingviews as well as PLC and Multi-inverters have been researched based on Kingview and methods be- RS-485. The problem of water resources automatic stabilizing control in water flow standard device is solved and the real-time mo- nitoring of water resources automatic stabilizing control by Kingview is realized.%针对水流量仪表测试装置中水源控制问题,基于组态和RS-485通信技术,研究上位机组态软件与PLC之间及PLC与多台变频器之间的通信方法,解决了水流量仪表测试装置的水源稳压自动控制问题,实现了组态软件对水源稳压系统的实时监控。
