RET Base Unit

RET - Synchronous Mobile Measurement System

The RET measurement system enables you to record measured values synchronously in time at various points on a vehicle, store them and evaluate them. With Big Data based optimization of vehicles and infrastructure you can find the proverbial needle in the haystack.

RET consists of various measurement nodes that are connected to each other via Mesh WLAN. This is used for time synchronization, triggering of measured values and transmission of data and time stamps.
