Supervision,forwarn and communication system in barrier enviroment of laboratory animal / 医学研究生学报

ABSTRACT

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.
