Complete Sensor Data and Vehicle Log Files

 

Track

Supply the exact values of carriage offset to the center line and the positions for each track number. Refer to the diagram under “Wander Pattern” to better visualize the track locations.

Wander

List the loading sequence corresponding to the track number of a wander.

Gear

Returns the Gear table, which contains information about the configured wheel loads.

Traffic Summary

Query Traffic Data between a start and end date.

MUX (Multiplexer)

The MUX table stores information about the static sensors, including sensor type and location. (MUX refers to the multiplexer units, which acquire the static sensor data.)

Static Sensor Data

Static sensors collect temperature data on an hourly basis.

 

SPU (Signal Processing Units)

The SPU table stores information about the dynamic sensors, including sensor type and location

Dynamic Sensor Data

Dynamic sensors are triggered by movements of the load vehicle. Therefore, dynamic sensor responses are collected only on days when the load vehicle is in operation. Dynamic sensor records are available for most passes of the load vehicle on the test items. However some gaps in the data are known to exist.

Custom Query

You may query the NAPTF database by using Structured Query Language (SQL). Note that data are read-only. Only “select” queries will be recognized by the database. Refer to the table map and definitions when formulating queries.
