UDR/P : Universal Digital Recorder / Universal Digital Player

The UDR/P includes the hardware platform (PC, acquisition board, storage media ...) and the software necessary to carry out the most demanding acquisition campaigns. It is a real numerical multisensor recorder configured according to the user's needs to allow the replaying at will and in a synchronized way of the recorded data.
The UDR (Recorder) is made of the physical platform and the acquisition software. The UDP(Player) is only the replaying software application, running on most of the hardwares.
.

	The first UDR realized for the European CarSense research project.

Acquisition hardware

The acquisition platform is an industrial PC, sized and configured to meet your needs. Its presentation and its cost are thus very variable.
Two points are very important when sizing :
- The desired recording rate.
- The desired recording time.

We deliver PC, all acquisition boards, but we usually don't deliver sensors, wiring and integration in the final environment. The harware can't be modify by the client.

Acquisition application (UDR)

This application is customized according to your acquisition needs and specifications. It is an easy-to-use application, but it is bolted and it cannot be modified. The application works only on the provided platform.

   Whatever customisation may be, this application allows:

• Acquisition of data chosen when designing the system,
• Manual recording starting and ending,
• End of recording in case of disk saturation,
• Data recording on disks for at least the duration specified in the contract.

Replay application (UDP)

This application is customized according to your replay needs, which are specified in the contract. It is an easy-to-use application, but it is bolted and it cannot be modified. You can only operate on data recorded using the UDR provided with it.

   Whatever customisation may be, this application allows to:

• Data base reading,
• VCR-like replay with time control (step by step, fast forward, fast backward, slow forward, slow backward).

General use

Qualitative data analysis: Data are played back at the appropriate pace, using the VCR.

Quantified data analysis: Recorded data are run through another ^RTMaps application to extract information. Delayed and virtual time data processing make extraction methods more precise and allowing very long processing, which wouldn't be possible in real time conditions.

Algorithms tests: Recorded data are run through a merging or processing algorithm. This algorithm is a component in an ^RTMaps application (created using the SDK). The different recorded scenarios make it possible to validate new algorithms in lab, without needing lots of expensive acquisition campaigns.
