Trial Project P-0136
Matched I&T Wish
Matched I&T Solution
Solution Feature
  • A touch sensor mounted 20mm in front of exist elevator panel such that an array of parallel infrared beams are emitted to detect a finger entering to active detection zone its vertical and lateral coordinates after it blocks and reflects some infrared beams back to the touch sensor.
  • The microcontroller processes the coordinates and generates the corresponding elevator button control command through RS-485 connection by closing the relay dry contacts connected to floor button dry contact. This mid-air touch avoids contact of button surface. To avoid false triggering, the microcontroller will ignore object size beyond allowable limit.
  • Exist dry contacts connected to original buttons are wired to new relay contacts in form of a logic "OR". There is no influence to exist buttons operation and create no safety concern in operation. It can be widely used in almost all existing elevator control panels with various button layouts.
  • Since the sensor projects a sheet of light beams for finger detection, it is not limited to work in the existing control panel. The sensor can be installed in anywhere in absence of a physical button panel in a flat surface to become a virtual control panel.
