33. CMV-NET Software Hardware BMS What is BMS ? What is BMS Gateway ?
Building Management System = BMS
A kind of software developed by third-party professional software company
Used to control all the intelligent equipment in the building, such as air conditioner、alarm、fire protection、elevator、light、water supply and drainage and so on
BMS software use its own language from its company, for example “A”
Every intelligent equipment use its own language, for example “B”
“A” and “B” can’t communicate with each other because of different language
BMS Gateway is kind of converter that used to transfer their language to each other
