Aggregation framework using low-power alert sensor

摘要

An aggregation framework system and method that automatic configures, aggregates, disaggregates, manages, and optimizes components of a consolidated system of devices, modules, and sensors. Embodiments of the system and method include a low-power alert sensor, a data aggregator module, and an interpreter module. The low-power alert sensor is a sensor that is continuously on and continuously monitoring its environment. The low-power alert sensor acts as a watchdog and triggers other sensors to awaken them from a power-conservation state when there is a change or event that occurs in an environment. The data aggregator module manages the set of sensors within the system and aggregates sensor data obtained from the sensors. The interpreter module then translates the physical data collected by sensors into logical information. Together the data aggregator module and the interpreter module present a unified logical view of the capabilities of the sensors under their control.

1. A method for aggregating data, comprising:
receiving an alert from a low-power alert sensor, the alert specifies that an incoming sensor is detected by the low-power alert sensor to be joining a sensor array, wherein sensors in the sensor array comprise a plurality of different types of sensors; responsive to the alert from the low-power alert sensor, updating a record of capabilities of the sensors in the sensor array, the record of the capabilities of the sensors in the sensor array updated to reflect an addition of capabilities of the incoming sensor, the capabilities of the incoming sensor being described by the incoming sensor and specifying a sensing function performed by the incoming sensor; detecting a change in an environment based upon an output from the low-power alert sensor, the change detected while the sensors in the sensor array in the environment are in a power-conservation state; selecting a sensor in the sensor array to awaken from the power-conservation state based on:
the change in the environment detected by the low-power alert sensor; andthe record of the capabilities of the sensors in the sensor array; responsive to selecting the sensor, awakening the sensor in the sensor array; receiving sensor data about the environment from the sensor in the sensor array woken from the power-conservation state; and aggregating the sensor data into aggregated data.
