Abstract
A distributed sensor system includes a set of spatially distributed base units and a central server both in communication with a data network. Each base unit includes a controller and one or more sensor modules where each sensor module includes a sensor configured to measure an air quality parameter. Each base unit transmits raw sensor data associated with each of the sensor modules over the data network and the central server receives the raw sensor data from the base units and stores the raw sensor data in a database.
Claims16
A distributed sensor system comprising:
- a plurality of spatially distributed base units in communication with a data network, each base unit comprising a controller and one or more sensor modules, each sensor module comprising a sensor configured to measure an air quality parameter, the controller in each base unit being configured to transmit raw sensor data associated with each of the sensor modules over the data network, the raw sensor data for a sensor module being identified by a sensor identifier uniquely identifying a sensor in a sensor module in a base unit and a board identifier uniquely identifying the base unit in the system;
- and
- a central server in communication with the data network, the central server comprising a data processor and one or more databases, the central server configured to receive raw sensor data from the plurality of base units and to store the raw sensor data in a database.
A method of performing calibration in a distributed sensor system comprising a plurality of spatially distributed base units in communication with a central server over a data network, each base unit comprising one or more sensors configured to measure an air quality parameter, the method comprising:
- maintaining calibration data for sensors in the distributed sensor system in a database, the calibration data for a sensor being associated with a sensor identifier uniquely identifying the sensor in a base unit and a board identifier uniquely identifying the base unit in the system;
- receiving raw sensor data from a first sensor in a first base unit;
- identifying the raw sensor data by a first sensor identifier identifying the first sensor and a first board identifier identifying the first base unit;
- retrieving the calibration data for the first sensor using the first sensor identifier and the first board identifier;
- adjusting the raw sensor data using the retrieved calibration data;
- and
- generating calibrated sensor data for the first sensor.
