实验动物屏障环境监控、预警及通信系统

目的：探讨实验动物屏障环境监控、预警及通信系统的设置模式。方法和结果：监控系统采用以工业计算机为核心的分布式系统，对屏障环境中温度、湿度、压差、氨浓度等参数进行了实时监测、显示，并可根据需要定时存储和打印的模式；预警系统为根据国家标准设置了上述参数的上下限，超限则采用声、光进行内、外多点报警、调控的模式；光照系统按国家标准中照度和明暗时间，分别设计工作照明与动物照明，其中工作照明人工控制，动物照明采用自动、缓控的模式；监视系统采用有线电视系统中监视器加视频切换器加多路摄像机的模式进行监视，并与智能化工业控制模块相联；通信系统利用小型程控交换机与若干电话终端，将单位内部电话接入程控交换机的输入端，实现内、外通信联系模式。同时在屏障环境内采用双声道立体声音响系统，设置了背景音乐，并根据非工作时段噪声强度，设置合适的音量，定时播放。结论：为实验动物屏障环境标准化、信息化及数字化管理提供信息。

Supervision,forwarn and communication system in barrier enviroment of laboratory animal

Objective:To design the mode of supervision, forwarn and communication system in barrier enviroment of laboratory animal. Methods and Results:Distribution inspect system of industrial computer center was used for live monitoring,displaying,reserving, printing temperature humidity,pressure,difference and ammonia density,according to necessity.The upper and low limit of parameter was set up according to national standard of laboratory animal,if parameter surpass the limit,it will warn the people on duty in multiple spots.Working and animal illumination were established respectively on the basis of illuminace light period of standard,the switch of working illumination was controlled by the people,but the later was controlled, automatically and slowly in order to disinterfere with physiology activity of animal.The mode of moniter add video together with multiple pickup camera in cable television were used,which binded wirh the intellectual industral control group.The communication system was designed using miniature program control changer and terminal telephone, which joined the unit inner telephone to communicate with outside. The double and stereophonic was used to install background music in this enviroment,which was timely played with suitable volume. Conclusion:This system provided the method for the administration of laboratory animal standardization?mathematics and informatics.
