Introduction[edit | edit source]
This Technical Note (TN for short) illustrates a Proof-of-Concept (PoC) that DAVE Embedded Systems made for a customer operating in the industrial automation market. The goal was to build a prototype of a high-frame-rate video recording/streaming system. In a typical scenario, illustrated in the following picture, this device would be used in fast automatic manufacturing lines for two purposes:
- remote monitoring
- detailed off-line "post-mortem" failure analysis.
In essence, the system consists of a high-frame-rate image sensor shooting a specific area of the line. The frames captured by the sensors are addressed to a processing
Streaming capability is used to monitor the production line remotely. Under normal operation, this is enough for the human operators to get an overview of the line while it is working. For this purpose, a simple low-frame-rate video stream (25 fps or something) over a local area network does the job.
The most interesting functionality is related to recording capability, however. As shown in the previous image, the production line is governed by a Programmable Logic Controller (PLC), which is interfaced to several actuators and sensors. The line is also subject to different kinds of faults. The most severe—for instance, a major mechanical failure—may lead to the automatic stop of the line. Thanks to the aforementioned sensors, the PLC is aware of such faulty conditions. In the occurrence of these events, it raises an alarm signal directed to the video recording system. This, in turn,
. this device would be used to shoot a particular portion of the line for:
recording streaming:
During normal operation,
The typical scenario in which this device would be used Under normal conditions, this camera streams
compresses the 60/30fps stream and streams it over Ethernet
Normal mode allows the human operator to remotely supervise the industrial machine where the device is installed
