Device abstraction system and method for a distributed-architecture heating, ventilation and air conditioning system

摘要

The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In various embodiments, the network includes a subnet controller configured to control networked devices via a data bus. The subnet controller is configured to be addressable over the data bus. An environmental sensor is configured to provide environmental data to the subnet controller, and is further configured to be addressable over the data bus independent of addressing the subnet controller. A user interface is configured to provide access by an operator to the network. The user interface is further configured to be addressable over the data bus independently of addressing the subnet controller and the environmental sensor.

1. An HVAC data processing and communication network, comprising:
an active subnet controller configured to control networked devices via a data bus and configured to be addressed over said data bus; an environmental sensor configured to provide environmental data to said active subnet controller and configured to be addressable over said data bus independent of addressing said active subnet controller; and a user interface configured to provide access by an operator to said network and configured to be addressable over said data bus independently of addressing said active subnet controller and said environmental sensor; wherein said active subnet controller is located in an enclosure with at least one of said environmental sensor and said user interface, and said network further includes an inactive subnet controller, that is a different controller than said active subnet controller, configured to operate as said active subnet controller when said active subnet controller malfunctions.
