The efficient flow of people in public spaces
Escalators are found in a lot of public buildings as well indoor as outdoor. Examples are at airports, shopping centres, railway stations, etc. It is not necessary that these escalators are working constantly. Only if a person is approaching the escalator, it should be turned on. In this way, power will be saved. The moment that no passenger is walking near the escalator there are two ways of saving power. The escalator switches to a lower speed or he is put in stand-by-stand so that the steps of the escalator come to a hold. With radar sensors a movement detection around the escalators is carried out. If a person approaches the escalator, the radar recognizes a movement. Then the ecalator switches on starts to move.
Radar sensors from Telco Sensors
SMM series (SpaceMotion)
The SpaceMotion of Telco sensors is a doppler radar sensor which is suited to detect movements in defined area arround the escalator. It uses micro waves and has a compact housing which make the sensor suitable to be placed behind a plastic wall. In this way, the sensor is totally eleminated out of sight.
The range of the radar sensor is classified in 'low speed and 'high speed' zones for fast- and slow moving objects. The distance distribution of these zones, but also the maximum range of the sensor itself is adjustable from 0 to 100%. Background suppression can also be set to filter out continuous motion objects, such as the moving handrail of escalators.
