SENSOR DATA INTERPRETER/CONVERTER METHODS AND APPARATUS FOR USE IN LOW POWER WIDE AREA NETWORKS (LPWANS)

摘要

Sensor data interpreter/converter methods and apparatus interpreting and converting sensor data transmitted by a plurality of sensors in a Low Power Wide Area Network (LPWAN) (in the up-link) in a unidirectional network and, in a bidirectional network, also converting human readable formatted information into sensor compatible machine-readable byte array data (in the downlink) are described. The interpreter/converter methods and apparatus utilize blueprints that fully de-fine the sensors (nodes) connected in the LPWAN. The blueprints include components providing information of every possible input and output an associated sensor has. The blueprints deter-mine how the interpreter/converter functions when converting sensor data to human readable formatted information in the uplink, and when converting human readable formatted information to sensor compatible machine-readable byte array data in the downlink. The blueprints are struc-tured to optimize the efficiency of transmissions in limited data bandwidth LPWANs.
