Auto-configuration and automation of a building management system

摘要

A building management system is disclosed that is automatically configured using a wireless mesh network data and sensor data to create a virtual floor plan. The building management system comprising a control processor, a plurality of lighting devices, and a plurality of control devices comprising lighting control devices, each directly controlling one or more of the lighting devices. The control devices intercommunicate with each other over a wireless network, and each control device comprises a light sensor detecting light intensity. The control processor creates the mesh graph of relative positioning of the control devices to each other using received wireless signal strengths of the control devices relative to each other. The control processor determines relative positioning of the lighting devices to the control devices using the mesh graph and received light intensity readings obtained by the light sensors of the control devices when each lighting device was turned on and off. The virtual floor plan comprises the relative positioning of the control devices to each other, the relative positioning of the control devices to the lighting devices, and room-by-room groupings of the plurality of control devices and the lighting devices.

1. A building management system that is automatically configured, comprising:
a plurality of lighting devices; a plurality of control devices comprising lighting control devices, each lighting control device directly controlling one or more of the lighting devices, wherein each control device comprises:
a bidirectional wireless network interface enabling the control devices to intercommunicate with each other over a wireless network, anda light sensor detecting light intensity; a control processor in communication with the control devices comprising a memory encoding one or more processor-executable instructions, which when executed by the control processor, cause acts to be performed comprising:
creating a mesh graph of relative positioning of the control devices to each other using received wireless signal strengths of the control devices relative to each other,cycling through and commanding each lighting control device to perform an on/off operation on one or more lighting device it directly controls, wherein for each on/off operation:
sending an on/off command to a lighting control device that directly controls one or more lighting device,designating the lighting control device receiving the on/off command as an operating lighting control device,receiving from each control device a pair light intensity readings comprising a first light intensity reading when the lighting device is turned on and a second light intensity reading when the lighting device is turned off,for each pair of light intensity readings, comparing the first light intensity reading to the second light intensity reading to determine whether the light intensity has changed, andrecording a data set for each control device with changed light intensity readings;determining relative positioning of the lighting devices to the control devices using the mesh graph and the recorded data sets, andcreating a virtual floor plan comprising the relative positioning of the control devices to each other and the relative positioning of the control devices to the lighting devices.
