Abstract

The invention discloses an elevator floor detection device based on a laser ranging technology. The detection device comprises a data processing module arranged at the top of an elevator car and a laser ranging module. According to the elevator floor detection device based on the laser ranging technology and an elevator system and method thereof, the laser ranging module is used for detecting theheight and the running direction of the car, the device system is simplified, the installation time is shortened, installation and maintenance cost is reduced, in addition, the detection precision ofthe laser ranging module can reach 1 millimeter, the collecting efficiency and the collecting precision of car information are improved, so that the elevator floor number judgment is more accurate, false alarm of the floor number is reduced, and zero error of the judgment of leveling and non-leveling is realized; meanwhile, the size of the elevator floor detection device in the scheme is small, the elevator floor detection device can be installed on a smooth surface of the top of a car roof, and compared with a traditional double-photoelectric sensor, the device is larger in installation position selectivity, and does not rely on an elevator guide rail at all; and more importantly, replacement and maintenance are more convenient, fast and time-saving, extra loss due to long-time stopping of the elevator can not be caused to a user, and the device is especially suitable for the society pursuing service at present.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to an elevator floor detection device based on laser ranging technology, an elevator system and a method. Background technique [0002] Among the existing elevator floor detection technologies, some use dual photoelectric sensors, some use Hall sensors, and some use air pressure sensors and three-axis acceleration sensors. In the detection technology, due to the low detection accuracy of the air pressure sensor, the error between the actual height of the car and the detection height is about 2cm, and it is also necessary to use a three-axis acceleration sensor to detect the running direction, which has complex structure of the equipment system, installation and maintenance. high cost. Contents of the invention [0003] It is necessary to propose an elevator floor detection device based on laser ranging technology. [0004] It is also necessary to propose an elevator s...
