Elevator non-contact combined button based on matrix infrared correlation signals

The utility model provides an elevator non-contact combined button based on matrix infrared correlation signals. The combined button comprises identifiers of all floors, function identifiers, column correlation infrared sensors, row correlation infrared sensors, a protruding outer frame and a single-chip microcomputer controller. The floor identifiers and the function identifiers are arranged on the same panel in a row and column matrix mode according to a certain distance. A protruding outer frame is installed on the periphery of the panel, a set of column correlation infrared sensors are installed on the upper side and the lower side of the protruding outer frame, and a set of row correlation infrared sensors are installed on the left side and the right side of the protruding outer frame. The elevator button can realize non-contact control, so that passengers can input instructions to an elevator without touching the button, and the problems that a conventional elevator button becomes a carrier for spreadin
