Abstract
The invention includes using multiple wireless vehicular sensor nodes to wirelessly receive multiple, time-synchronized vehicular waveform reports from the nodes to create a time synchronized system report, and preferably a time synchronized vehicular report. Each vehicular waveform report approximates a raw vehicular sensor waveform observed by a magnetic sensor at the node based upon the presence of a vehicle. The vehicular waveform reports, the time-synchronized system report, and the time synchronized vehicular report are products of this wirelessly receiving process. The invention includes apparatus supporting the above outlined process. Reception of the vehicular waveform reports may be time interleaved.
Claims40
A method of using a first wireless vehicular sensor node and a second wireless vehicular. sensor node, comprising the steps of:
- creating a time synchronized system report from wirelessly receiving a first vehicular waveform report from said first wireless vehicular sensor node time-synchronized with a second vehicular waveform report from said second wireless vehicular sensor node;
- wherein said first vehicular waveform report approximates the first raw vehicular sensor waveform observed by a first magnetic sensor at said first wireless vehicular sensor node based upon the presence of a first vehicle;
- wherein said second vehicular waveform report approximates the second raw vehicular sensor waveform observed by a second magnetic sensor at said second wireless vehicular sensor node based upon the presence of a second vehicle;
- wherein said first wireless vehicular sensor node operates said first magnetic sensor;
- and
- wherein said second wireless vehicular sensor node operates said second magnetic sensor.
