Building management system with eventseries processing

A method of data management for a building:

• receiving, by a processing circuit, a plurality of data samples, each of the plurality of data samples comprising a data value and a timestamp, the plurality of data samples generated by building equipment;
• assigning, by the processing circuit, a sample state to each of the plurality of data samples based on the data value of each of the plurality of data samples;
• generating, by the processing circuit, one or more events based on the timestamp of each of the plurality of data samples and the sample state assigned to each of the plurality of data samples, each of the one or more events comprising a start time, an end time, and an event state;
• generating, by the processing circuit, an eventseries comprising the one or more events;
• receiving, by the processing circuit, a particular data sample after generating the eventseries, the particular data sample comprising a particular data value and a particular timestamp, the particular data sample generated by the building equipment;
• and
• performing, by the processing circuit, at least one of extending a last event of the eventseries or generating a new last event of the eventseries based on the particular data sample.

A building management system comprising:

• building equipment;
• and
• one or more processors configured to:
• receive a plurality of data samples from the building equipment as the building equipment generates the plurality of data samples, each of the plurality of data samples comprising a data value and a timestamp;
• assign, as the plurality of data samples are received from the building equipment, a sample state to each of the plurality of data samples based on the data value of each of the plurality of data samples;
• generate, as the plurality of data samples are received from the building equipment, one or more events based on the timestamp of each of the plurality of data samples and the sample state assigned to each of the plurality of data samples, each of the one or more events comprising a start time, an end time, and an event state;
• and
• generate, as the plurality of data samples are received from the building equipment, an eventseries comprising the one or more events;
• and
• update the eventseries by performing at least one of extending a last event of the eventseries or generating a new last event of the eventseries based on particular data samples received after generating the eventseries.
