Contactless elevator control system and method

The present invention provides a contactless elevator control system and method. The system comprises an infrared touch sensor, a relay control device and an elevator button control device, wherein: the infrared touch sensor emits an array of multiple infrared beams, receives reflected infrared beams, calculates a vertical and lateral displacement, determines a corresponding coordinate information, calculates a corresponding elevator button, and sends a corresponding control; the relay control device drives the corresponding relay contacts to close. The solution uses the infrared touch sensor to achieve contactless control of elevator buttons, reducing the risk of spreading bacteria and viruses when touching the elevator buttons. elevator button infrared touch sensor p relay control device control device Fig.1 transmitter receiver microcontroller Fig.2
