In the development phase of a new vehicle, engineers would like to access the data relevant to particular events, but need to filter it to their particular requirements, in order to avoid being swamped. With CAN based systems, the large amount of data makes the problem especially difficult. To help vehicle development engineers record and manage data for evaluation, statistical analysis and troubleshooting, Accutest has introduced the FlightRecorder – FR1000.
Consisting of a small, rugged, aluminium black box measuring 160 x 134 x 44 mm that can be mounted in the engine compartment, the cab or under the vehicle, the FlightRecorder can record multiple events on non-volatile flash cards.
The unit operates on 8 to 30V DC and so is suitable for cars, trucks, buses, agricultural and construction equipment and a host of other everyday and military vehicles. Power consumption is only 300 mA in normal operation and a mere 10 mA in sleep mode. It will operate reliably in all conditions between -30 and +70° C.
Flash cards are available from 8 to 300Mb to store up to 15 million messages and there is error frame detection and recording, plus time stamping to a resolution of 10 µsecs. The unit is configurable for multi-trigger start/stop recording, continuous recording with a circular buffer, manual or event triggered start/stop, and single shot or repetitive recording with configurable pre and post trigger buffers – each on 2 separate CAN channels.
Normal configuration is via a PC running Windows 95, 98 or NT4, but there is also a keypad option to allow monitoring or re-configuration on the move. Triggered events are signalled to the PC or via an SMS message on the GSM mobile phone network. Collected data can be downloaded directly to the PC, via the flash card or via the GSM mobile phone network. It is also possible to re-configure the FlightRecorder remotely anywhere in the world via the GSM link.
