The CASTT project “Real Time Analysis of Data from Wireless Sensor Networks in Automotive Testing” is focusing on wireless sensor technology and its applications in automotive testing and development. The overall goal is to strategically and technically meet challenges and requirements in developing vehicles and services, thus meeting new demands from global automotive industry customers.
The resulting modular system consists of three parts. 1. A web portal through which a user can manage different kinds of measurement assignments, 2. A Sensor part, and 3. An analysis part.
The service set generated, and the modular three part system which generates it, can be adapted and specialized to measure, analyze and support conclusions based on different kinds of sensor data.
The portal module is a server which acts both as frontend to the user, to initiate and manage measurement assignments, and communicating measured data with the wireless communication units inside monitored vehicles. Furthermore, the portal can support distributed as well as co-located engineering collaboration teams in different settings. That is, the portal can be used locally and as a shared application in a distributed collaborative setting.
In the sensor part, part two, several types of sensors can be supported, including “Mulle,“ developed by EISLAB. Several types of sensor data can be collected by connecting different types of sensors to an onboard vehicular communication unit (VCU). Ongoing work includes defining the semantics of the data collected. The purpose is to improve analysis of the collected data, thus improving human conclusions and future engineering decisions.
Ongoing work in the analysis part (part three) of the modular system includes creating demonstrators whereby different kinds of queries to data streams are defined in order to support data analysis.
The modular services are aimed to be able to be used by vehicle vendors, service development collaboration teams and teams concerned with customer vehicle usage.
