To solve the problems of low efficiency and manual estimation being requested for fermentation tank feeding in chemical enterprises, the automated operation of control system for feeding is established by adopting embedded technology. Considering the importance of safety in chemical production, to avoid non-timely monitoring of the production parameters and alarming not in real time, the monitoring system based on industrial Ethernet is built to detect the parameters in real time. The automation management level of the enterprise is enhanced by adopting Internet of things. Thus, the overall chemical enterprise becomes an integrated network management system that consists of safety production, monitoring and warning. The system effectively enhances the automation control level and information management level, as well as enhances the safety warning level into a new stage.%针对化工企业发酵罐补料需人工估测、效率低的问题，采用嵌入式技术建立控制系统对补料实现自动操作。考虑化工生产中安全的重要性，对各项生产参数的监测不及时、不能实时报警的问题，建立基于工业以太网的监测系统进行参数的实时监测。利用物联网技术提升了企业的自动化管理水平，从而整个化工企业成为集安全生产监测预警于一体的综合网络管理系统。该系统可有效提升企业生产的自动化控制水平和信息化管理水平，并将企业的安全预警水平提升到一个新的高度。
