Building management system with distributed data storage and processing

摘要

A building management system (BMS) including device controllers configured to monitor and control one or more heating, ventilation, or air conditioning (HVAC) devices and to store and process time-series data associated with the HVAC devices. The BMS includes a BMS controller that is communicably coupled to the device controllers. The BMS controller is configured to generate and send one or more processing sub-requests to at least one of the device controllers based on a processing request requesting time-series data associated with an HVAC device. The BMS controller is configured to receive one or more processing results from the at least one of the device controllers and join the one or more processing results into a joined result. The BMS controller is configured to provide the joined result to a requesting entity. The device controllers are configured to receive and process processing sub-requests and send results to the BMS controller.
