Room monitoring
3D camera system instead of safety sensors
Room monitoring. The Austrian start-up Tofmotion has developed an alternative option for safe room monitoring in industrial environments: Tofguard makes it possible to use the 3D-based Time of Flight (ToF) camera method with safety approval for the machine industry for the first time.
The new Tofguard product group is based on the TFM IC5 outdoor cameras, which Tofmotion has now developed further for safety applications: The new ToF (flashLIDAR) cameras are certified and approved in accordance with EN 13849 (Performance Level D) and EN 62061 (SIL 2, Cat.). With a frame rate of up to 100 frames per second, the 3D cameras with QVGA resolution are faster than average. All images are processed immediately using an onboard processor and the information derived from them is forwarded directly to control systems. The data transfer remains as lean as possible. Autonomous transport systems can therefore move many times faster and the speed of robots is not restricted by slow sensors.
Robust cameras for outdoor use
The interference-free detection of objects is carried out using infrared lasers. The camera therefore works reliably both in dark production environments and in the bright summer sun. The optical power can be flexibly adapted to the lighting conditions in the range from 0 to 16 watts, whereby laser class 1 and therefore eye safety is always guaranteed. The operating range of 0.05 to 10 meters makes it possible to detect both very close and distant objects. The cameras can be put into operation via Plug & Play.
Software packages for various applications
Tofguard is available as a safety-certified camera for industrial applications without specific pre-configuration, and the manufacturer also offers the cameras including suitable software for defined areas of application. This results in solutions that enable interaction and autonomy in industrial applications. They surpass the functionality of safety sensors: While single-beam sensors only ever scan the environment selectively and sequentially, the 3D cameras from tofmotion capture the entire working area with every image.
The Spotguard product will be available for this purpose: Here, the camera monitors a freely definable space, such as a protected area around a robot workstation. If a person or object approaches and violates defined danger zones, the camera's OSSD interface triggers a corresponding reaction in the machine controller. Next, Tofmotion will launch a product for the use of driverless transport systems. dsc
