Seen’s IRIS60/8 sensor uses an infrared LIDAR to detect the reflective strip found on high-visibility safety vests and markers.
IRIS60/8 is a mounted on mobile plant and detects the retro-reflective strip on standard Class II and III high-vis apparel. The major advantage of IRIS60/8 over most other industrial pedestrian detection systems is that it does not require ground-personnel to carry an electronic tag, or change their behaviour in any way.
IRIS (“Infrared Retroreflector Identification System”) is a patented technology developed by Safety Lab Holdings. The IRIS60/8 continuously emits pulses of non-visible laser into blind-spots around the machine. The driver receives an audible alert if someone is detected in the blind-spot.
Detection range and field-of-view
IRIS60/8 has been optimised to detect ground personnel working near mobile plant. It features a 60 x 45 degree detection area and an 8 metre detection range.
Multiple sensors can be used to create coverage zones tailored to particular applications. For example 3 sensors can provide full 180 degree coverage behind a vehicle. Depending on the application requirements, the detection start and finish distance can be configured to lie anywhere within the 1 to 8 metre detection range.
IRIS60/8 provides reliable detection performance under all lighting conditions, from complete darkness to intense glare from the sun on wet pavement.
Standard Class II safety vests typically have a total of about 3000cm2 (465in2) of reflective strip applied to them. The IRIS60/8 sensor requires a minimum of approximately 75cm2 (11.6in2) of reflective material within its field of view. This enables reliable detection even when the person is in a sub-optimal orientation such as side-on or crouched down.
Safety and compliance
The IRIS60/8 complies with relevant US and EU standards including Class-IM laser eye safety, EMC, REACH, ROHS.
The sensor has no moving parts and can withstand the shock and vibration associated with heavy machinery. The IP67 rated enclosure ensures comlete weather resistance for year round indoor or outdoor operation.
In-cab audible alert
Because an operator inside an enclosed cab (like a front end loader) won’t hear the alert coming from the external sensor, an additional beeper unit is installed in the cab to give the driver a loud audible alert when the sensor is activated.
IRIS60/8 sensors feature an M12 connector so a video camera module can be attached to record detection events as they take place. Automatically triggered by a detection, the video camera saves a 30 second segment of footage around the event for later analysis. This feature offers heath and safety managers a unique opportunity to capture and review close calls that would otherwise go unreported. COMING SOON
