Screening of passengers and movement in the wrong direction access in airports

Security is one aspect of the utmost importance at all airports in the world governed by national and international laws, including the Act of German aviation safety (LuftSiG) in Germany and 300/2008 standards and 185/2010 EU, application throughout Europe. According to these laws and rules, airports are divided into zones of strictly controlled access security. More specifically, this means that the monitoring of the crossing points between the side of Earth and the "air side" is a task of utmost importance. Passengers to embark arrive at the door on the side of air (located after security control) from the side of Earth, while passengers disembarking are moving in the opposite direction through the barriers to entry.

To this end, airport providers seek solutions of sensors for their access systems that they detect passengers in a reliable manner and prevent that they circulate in the wrong direction and end up in the air side. It should also prevent objects to arrive in the same way by air. Sick, specialist in security tasks and intralogistics in airports, provides the 'duo' concept and high-resolution solar grids, which guarantee the reliable detection of objects and movement in the wrong direction.

These requirements are fulfilled using a photoelectric grid of Sick (MLG) already accepted at many airports as a reliable sensor solution. The detection of movement in the wrong direction is performed by the concept 'duo', i.e. with two grids MLG installed a few millimeters of distance between himself and delayed response. Solar grids resolution is so high that even if someone tries to push a flat object on the ground or at the top of the barrier or throw something through it, it will be detected and effectively marked.

Passage through the barrier of access in the right direction from the runway, to collect the baggage, for example, leaving the security zone, is recorded as correct. If something or someone trying to cross the barrier of access in the wrong direction, immediately activates an alarm signal. At the same time, any barrier of access by air that can remain open is blocked to prevent the passage of the safe areas.

This system is based on a resistant photoelectric grid which satisfies the requirements of the application environment: a compact stainless steel housing protects it from mechanical damage and fully respects the design of the system of barriers to entry. The detection is extremely effective because the brightness and glare from surfaces as a cart of aluminum or other effects of the ambient light, as the light that passes through the ceiling of glass or fluorescent lamps in the area of the barriers to entry, do not affect the reliable detection of passengers or objects. Because both the electronic elements of evaluation and the switching outputs are integrated into the casing of photoelectric grid, don't need any external module. The result is the photoelectric grid can be integrated with ease, both mechanical electrically, as in the system of barriers to entry.

Sick also offers Airport suppliers and their clients a global service qualified for rapid response in the areas of planning, implementation, maintenance and repair, thereby ensuring the safety of the investment and the system.
