SICK’s LMS range of 2D laser scanners are for protecting outdoor open spaces, even where there are frequent vehicle movements, the developers say. One scanner can cover an area the size of a football pitch.
Both intrusion and anti-collision protection have been made more customisable and adaptable for building security, distribution centres and critical infrastructure, including railways, airports and bridges, thanks to developments to the SICK LMS141 range of time-of-flight laser scanners.
Neil Sandhu, SICK (UK) Product Manager says: “SICK laser scanners are well known for their robust and reliable protection, even in challenging environments or weather. Now, with the LMS 141, security monitoring and collision protection for a whole range of complex profiles and changing situations is possible while avoiding false alarms.”
The new LMS 141 2D laser scanner has been optimised for building and outdoor security, providing scanning protection in which the fields can be precision-configured through an function to suit the shape, size and permitted areas of almost any location. Scanners can also be integrated with CCTV and lighting, for full image identification purposes.
Regular moving objects such as vehicles in designated spaces can be taught-in to the sensor software, and the LMS 141’s Core and Prime options offer differing degrees of complexity depending on the application, with automatic or configured fields and the ability to teach-in with or without a PC. The unit also allows for gradual profile build-up to avoid false alarms, for example, with snow accumulation, piles of leaves or grass growing.
Neil Sandhu adds: “The LMS 141 has our widest-ever scanning field, capable of detecting even black targets over an area up to 30 metres by 20 metres, almost football pitch sized. So you can protect large areas like building perimeters and vehicle yards with very few scanners. Because you can define and configure a number of fields and profiles to allow for changing conditions over time, fields can be easily be set. For example, you can allow for pre-set access paths during the day, which are automatically protected at night, or you can guard around objects, vehicles, windows and doors, allowing set proximity only at designated times.
“The LMS 141 offers invisible protection with superior performance to non-laser technologies such as radar and infrared, at a competitive price to installing a high security fence, for example.”
With its IP67, tamper-resistant housing, the product has a temperature range of between minus 40 degrees C and plus 60 degrees C, can operate independently of changing light, and is unaffected by rain, fog and snow. The time-of-flight laser scanner emits an infra-red laser beam pulse which scans a field range up to 270o via a rotating mirror. The scanner’s sensor measures the return time of each pulse to build a profile which is compared to the taught-in profile. The unit can be mounted horizontally, on its back, vertically, on the floor or on posts or walls to provide the required protective field.
Connected via a UV-resistant cable, the LMS141 is available with Ethernet and CAN communication for integration to local control networks; smartphone alarms can be set up via a PC for remote monitoring. The compact, discreetly coloured unit is only 162mm by 102mm by 106mm and 1.1kg for easy installation.
