E-Net温湿度监控系统在普通环境动物实验室中的应用

Application of the E-Net System on Temperature and Humidity Monitoring in Conventional Animal Laboratory

我单位普通环境动物实验室建于2005年,使用的是多组分体式小型中央空调对不同动物房间分区进行温度控制。为了达到GLP认证要求,在不改变原有系统的情况下,设计应用了基于多CPU远程温湿度监控系统。其中现场温湿度记录仪应用先进的单片机技术,智能程度高,数据精确,数字信号不会产生传输误差或损失,通过单独控制不同区域或房间的加热、制冷、加湿、除湿设备实现温湿度控制或报警,还可通过扩展接口进行其它设备的实时控制和远程控制。该系统安装简单,管理方便,使用一般计算机即可实现多点远距离通讯和监控,并具有自动记录、自动控制、自动数据管理功能。该系统性能稳定可靠,不仅大大节省了投资,还具有很强的通用性和推广应用价值。

The conventional animal laboratory of Zhengzhou University was established in 2005, and the room temperature was controlled by multi-groups of small split central air-conditioners. To meet the GLP requirements, a remote temperature and humidity monitoring system based on muhi-CPU was designed and applied without changes in the original system. The advanced single-chip technology was applied in temperature and humidity recorder, which is of high degree of intelligence and data precision. Independent control system in each region or room achieved temperature and humidity control or alarm, and real-time and remote control of other devices can be operated through the extending interface. This system has the capabilities of automatic recording, control, and data management, but installation and management of the system is easy. Using the conventional computer, remote communication and multi-point monitoring can be achieved. This system is stable and reliable so that investments will be saved significantly. It can be commonly used and promoted widely.
