The present invention provides a contactless elevator control system. 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 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 touch sensor to achieve contactless control of elevator buttons, reducing the of spreading bacteria and viruses when touching the elevator buttons.
