摘要
介绍了一种多库房药品库的远程温湿度监控系统。系统为两级分布式控制结构,上、下位机系统处理器采用高速 C8051F 单片机,利用 RS-485总线将多个库房联为一体;温湿度测量选用数字化传感器件,形成单总线传感器网络,极大地减小了线缆数量及布线难度,提高了系统的可靠性;人机界面采用触摸屏,完成各库房温湿度的设定值设置和实测值显示,实现基于触摸屏操作的远程监控。
Introduced design of the multi-room measurement and control system ol temperature and humidity in drug storeroom. Based on C8051F MCU and RS- 485, all rooms combined to one DCS system.The temperature and humidity measurement was accomplished by 1 - Wire sensors, because all sensors were combined to one sensor network, so this reduced link wires excessively and enhanced system reliability. GOT(Graphic Operation Terminal) was used for setting the set value and displaying the measure value of temperature and humidity, therefore, the remote surveillance and control of system was realized.
