Autonomous vehicles come with a large number of sensors, multiple LIDARs, RADARs, and high-resolution cameras. It features an array of technologies such as CAN FD, Automotive Ethernet, 10GBASE-T (IEEE 802.3an™), etc. They are capable of generating a massive amount of data in a short amount of time. When you want to record the vehicle data from the autonomous cars to test and verify, it is desirable to record everything that autonomous vehicles can produce at high speed. How can you possibly record that much data? Even if you find a device with high-bandwidth logging and a high storage capacity, how do you offload and analyze terabytes of data? Not only does it take forever to offload terabytes of collected data, but it will be very hard to store that data on a computer.
What is the current solution? There is a trunk full of equipment patched together. Off-the-shelf CPUs and hardware require a lot of power and typically are not configured for large-scale data storage. In other words, desktop PC’s and many devices from many providers that are not designed to work together. It’s an unreliable solution, leaving you to integrate the components and recover the data from many devices. All of these devices also have a relatively large power draw.
Intrepid Control Systems’ RAD-Gigalog allows you to record multi-gigabit data streams and store up to 6+ Terabytes of data. It can record streams from 100BASE-T1, 1GBASE-T, 10GBASE-T, and GMSL / FPD-Link III cameras. The RAD-Gigalog’s power consumption is only 18W (1.5A @ 12V) and features a supercap for power failure protection.
The RAD-Gigalog supports high-speed SerDes (serializer/deserializer) camera interfaces like Texas Instruments FPD-Link III or Maxim GMSL for the direct camera or sensor connection with a capacity up to four cameras.
Need more channels, cameras or storage space? No problem! With the RAD-Gigalog you can stack and sync multiple loggers. For example, with two RAD-Gigalogs you can log up to eight cameras at the same time, and forward uncompressed video data over Ethernet to an autonomous controller or Vehicle Spy software. Of course, you can offload the data from the USB 3 or High-speed 10 Gigabit Ethernet (10GBase-T), or simply play back logged data directly from RAD-Gigalog to your bench using Vehicle Spy. The RAD-Gigalog reduces a trunk full of equipment down to a portable size!
Intrepid is a Platinum Exhibitor at the 2018 IEEE Ethernet & IP @ Automotive Technology Day this 9 – 10 October in London, England. Come to Intrepid’s booths 4 & 15 to see the RAD-Gigalog in action!
