The design and assembly of environmental monitoring and control system for large-scale pig house with fermentation bed helped to solve the problem of environmental automatic control in piggery.The sensors would monitor the temperature,humidity,light,wind direction,wind speed,CO2,NH3and other parameters.On-line real-time data collection was achieved.The expert system was constructed to control the temperature in piggery below 30℃,to control the air and mattress humidities higher than 65%.Under the conditions of different season or different wind speed,even in day and night,the control actuators were different.The actuators included fanning wet curtain,lighting,micro spraying,spraying,propeller fan,electric aluminum alloy shutter and spraying systems on the roof.The actuators were integrated,and they control the piggery environment simultaneously.The system also designed the remote video monitor interface,parameter-monitoring curved interface and operation interface,which provided a good man-machine interface. 展开更多

The temperature is an important factor affecting the stability of electron beam orbits.For almost all accelerators,a well-working cooling system and the monitoring system are needed to keep the temperature constant. In this paper,the temperature monitor system for HLS based on EPICS,including its hardware,software and history database,is briefly introduced.It has been indicated that the system satisfies the requirement of machine study and operation. 展开更多
