基于PLC控制的自动电热水装置安全保护系统设计

摘要

Automatic electric water heater is eliminated backward coal-fired boiler enterprises to solve water supply problems, and according to the domestic production or life often needs for hot water supply users (especially mining enterprises) needs a water heater design. In order to improve the safety and reliability of the device, this paper designs an automatic safety protection system based on PLC control.%自动电热水装置是为企业淘汰落后的燃煤锅炉解决热水供应问题,并根据国内因生产或生活需要经常供应热水的用户单位(特别是矿山企业)的需求,设计的一种热水装置.为了提高该装置的安全性和可靠性,本文设计了一套基于PLC控制的自动安全保护系统.
