摘要
针对制药企业GMP车间空调净化系统测控点多且分散、控制复杂的特点,提出了RS-485总线的空调净化DCS系统设计方案。实现对现场温度、湿度、压差、风速的监控,取得了较好的应用效果。
A distributed control system based on the RS485 bus is applied to the system of air conditioners and decontamination in the GMP workshop of a pharmaceutical factory so as to realize the moniforingcontrol of temperature,humidity,differential pressure and wind velocity.The application has proved that the system is very effective.
