摘　　要：根据生物洁净室负压环境控制的基本要求,利用PLC技术和计算机控制软件实现系统负压梯度的控制,同时结合计算机技术实现压差控制、故障分析、过程监控以及信息化管理,设计了生物负压环境控制系统,保障负压环境的安全可靠运行。According to the basic requirements of the negative pressure environment control in biological clean room,PLC technology and computer control software are used to control the negative pressure gradient of the system. At the same time,the differential pressure control,fault analysis,process monitoring and information management are realized by combining with computer technology. The control system of biological negative pressure environment is designed to ensure the safe and reliable operation of the negative pressure environment.
