摘要:

目的 提升静脉用药调配中心（pharmacy intravenous admixture services，PIVAS）对洁净室压差、温湿度的实时监测和预警能力，最终实现洁净室环境及关键设备自动化、智能化的远程调节。方法 通过可编程序的逻辑控制器（programmable logic controller，PLC）系统介导的智能环境在线监测调控系统的设计与应用，并比较该系统与传统环境监控系统的优缺点。结果 智能环境在线监测调控系统能与PIVAS智能运营服务平台（PIVAS operation service of intelligent platform，PSIP）有效结合，基本实现了移动终端对洁净室压差和温湿度的实时监测与预警、历史数据的有效追踪与分析、远程压差/温湿度调节的自动化与智能化；实现了洁净室内关键设备超净工作台的状态查看与远程控制等功能。异常监测报警记录由使用前的平均5次/月上升至20次/月；异常情况的处理时间由每次（48±4.5） h下降至每次（3±1.5） h；相关人力时间由每月（540±60） min缩短至每月（30±10） min。结论 智能环境在线监测调控系统的应用，实现了PIVAS洁净室各工作区域压差/温湿度的实时监测与调节、超净工作台状态查看与远程控制，不仅有效地保证了PIVAS洁净室的环境安全与全程可追溯，也极大地便利了工作人员的操作。

Abstract:

OBJECTIVE To improve the real-time monitoring and early warning for differential pressure, temperature and humidity in pharmacy intravenous admixture services(PIVAS), and finally realize the automatic and intelligent remote regulation of clean room environment and key equipment. METHODS By application of on-line monitoring and control system for intelligent environment based on programmable logic controller(PLC) system, the advantages and disadvantages of the system are compared with the monitoring system for traditional monitoring system. RESULTS The on-line monitoring and control system of intelligent environment was put into use in PIVAS clean room, and it could be effectively combined with PIVAS Operation Service of Intelligent Platform(PSIP), which basically realized the real-time monitoring and early warning for differential pressure, temperature and humidity, the effective tracing and analysis for historical data, the automation and intelligentization of remote differential pressure/temperature and humidity adjustment, and the status check and remote control of the ultra clean working platform of the key equipment in the clean room. The alarm records of abnormal monitoring increased from 5 times per month to 20 times per month. The treatment time of abnormal condition decreased from (48±4.5)h per time to (3±1.5)h per time.The related manpower time was shortened from (540±60)min per month to (30±10)min per month. CONCLUSION The application of on-line monitoring and control system for intelligent environment has realized the real-time monitoring and automatic control for differential pressure/temperature and humidity in each working area of PIVAS clean room. Also the status check and remote control of the ultra clean working platform. Not only effectively ensure the environmental safety and whole process traceability of PIVAS clean room, but also greatly facilitate the operation of staff.
