Remote Access to Vehicle Test Measurement Data (RA2VTMD)

Abstract

The objectives of this project are the design and test of a system called by the author RA2VTMD (Remote Access to Vehicle Test Measurement Data) with the intention to obtain more quickly the results measured in a vehicle test done by any car maker. The RA2VTD was designed following three blocks: sensor node, destination node and nodes communication. Sensor node has the mission to acquire the data measured in a vehicle test, stored it in a data logger and generate a file to be sent via wireless to the destination node. Destination node has the task to upload the content of this file to the network (Intranet/Internet) using a server and a visual application to analyze it or to download it at office. Lastly the nodes communication is in charge to transfer this file from sensor node to destination node using FTP protocol, and also to assure that all the data is well transferred. Finally the system was validated until the acquisition step, due to the impossibility to do the complete system validation in IDIADA (Nissan box) test tracks for confidential requirements. It’s important to know that IDIADA complex has a strictly rules in this aspects, and overcoat in wireless transmission data. To validate the system, two real experiments have been studied using two sensors: one to measure the temperature of the clutch disk, and other to measure the posture of a vehicle.
