COM Encapsulation Techniques of Ventilation Network Solution

The status quo of ventilation network solution software at home and abroad was studied in detail. It shows that China's current mode to develop ventilation network solution software has many outcomes, such as strong dependence on operation system, closure and uniform design style, etc. The significance and difficulties to encapsulate ventilation network solution as COM are also discussed. A COM is developed with VB.NET to illustrate the internal realization of ventilation network solution, and finally a new cooperation pattern of software companies and research organizations is proposed. Under the new pattern, a platform developed by a software company invokes ventilation network solution program encapsulated as COM by a research organization. The new cooperation pattern guarantees program's encapsulation and grafting property, shortens developing period, and reduces costs.
