Abstract:
1. A method of obtaining data about a structure, comprising: a. providing a plurality of sensor modules on the structure, wherein each said sensor module includes a sensor, a processor, a sensor module precision timekeeper, and a sensor module transceiver, wherein said sensor provides data related to loading; b. providing a base station; c. periodically wirelessly receiving a broadcast resynchronization timing packet with each said sensor module transceiver, wherein said broadcast resynchronization timing packet received by each said sensor module transceiver includes a common resynchronization time value; d. periodically resynchronizing each of said sensor module precision timekeepers based on a signal derived from said resynchronization time value; e. digital sampling of said sensor module sensor in each said sensor module to provide digital sensor data, and providing a time stamp to said digital sensor data wherein time in said time stamp is provided by said sensor module precision timekeeper; f. wirelessly transmitting data from each of said plurality of sensor modules to said base station, wherein said data is derived from said time stamped digital sensor data; and g. receiving and aggregating said data from each of said plurality of sensor modules in said base station.
