摘要
水资源的短缺和消防火警的频繁出现使得恒压供水问题显得尤为重要,本文基于PLC和内置PID的变频器构建了恒压供水控制系统,该系统能够进行自动调节生活和消防恒压供水、小流量节能、故障检测和报警,以及提供各种保护功能。系统具有可靠性高、效率高、节能效果显著和动态响应速度快等特点。
It is important to design constant pressure water system due to the scarcity of water and high frequency of fire. The paper sets up a constant pressure water control system based on PLC and transducer with PID inside. The system has many functions such as self-regulation of living and fire fighting water pressure, saving energy through little flux, failure detection and alarming, and many kinds of protect functions. It has the characteristics of high reliability, high efficiency, saving energy, and high dynamic response speed.
