Visualizaion in Building Automation system (2)
For people along the assembly line
Visualization exists not only at the final graphical presentation for the operator, but also during the BAS engineering process.
Big companies tend to divide one thing into sevral tasks, such as hardware design, software design and graphics design. Each specialist concentrate on his/her own business. And there is little consideration on how to pass the information seamlessly.
For example, the hardware designer read through all the spec. and mech. drawings to understand the structure of the control system. The graphics designer may have to go through them again to determine the menu system/navigation structure. These is because the hardware design does not consider the graphics when he/she create the control drawing index.
Another example will be the control sequence. The hardware designer copies or rewrites the control sequence for each unit/plant. But those sequence are not obvious for the software designer to get the idea at first look. He/she has to read through carefully to figure out what the program should be. And normally software designers have a standard software library. It takes quite awhile for him/her to pick the standard module and modify them. Is there a signal system on the hardware drawing to expedite this?
