School Building Automation Project

Project Introduction:

In this case, we got to use PLC to control the high school air conditioner system. All of the AC signals should be integrated in SCADA. The control process should complete in PLC but all of the important signals should be shown on the screen. When the alarm occurs, the operator should manage the emergency situation. Besides, the rest of the PC could be the web client. The staffs of the school could monitor the screen by IE at any time.

System Requirement:

Advantech Studio(SCADA)

Mitsubishi A type PLC

OPCTechs Mitsubishi OPC server

1 personal PC (WIN2000)

Conclusions:

The air conditioner system should operate normally all the time. The stable system is very important for AC control. We use stable PLC to control the AC operated alternatively. It could increase the life of AC and it could also save the electricity power. Using the powerful Advantech SCADA, we could monitor and control the PLC by OPC server. The client side PC could see the screens the same as the server through IE.
