Intelligence elevator photoelectric switch based on two -dimensional code floor information

The utility model provides an intelligence elevator photoelectric switch based on two -dimensional code floor information, including encoder count module, calibration module, elevator control module and host system, encoder count module and calibration module link to each other, encoder module is used for counting elevator floor information, calibration module is used for proofreading elevator floor information, does calibration module pass through RS 485 link to each other with elevator control module, elevator control module passes through the CANBUS bus and links to each other with host system. The utility model discloses a set up calibration module, based on two -dimensional code elevator information, proofread coding counter's floor numerical value for elevator position's accuracy nature has had the improvement of matter, has avoided the phenomenon of indiscriminate layer of elevator and staggered floor. In addition the utility model provides a two -dimensional code display module is the activity display
