Problems solved by technology
If the control device misidentifies the position of the car or the current landing, that is, a floor fault occurs, it may cause the following problems: (1) the elevator cannot run to the correct landing; (2) when the elevator runs to the end station, due to The running speed is too high and rushes out of the limit position, resulting in accidents of rushing to the top or squatting at the bottom; (3) The elevator cannot be accurately leveled
However, due to the slippage of the steel wire rope and the interference and correction deviation of the level switch, there is a risk of floor misalignment during elevator operation, especially in the case of re-running after a power outage. If the car is moved during a power outage, it is easy to cause a floor mislocation

Embodiment Construction
[0017] The elevator hall identification device of the present invention includes a plurality of IC cards and a card reader. see figure 1 , which is a schematic diagram of the installation of the elevator hall identification device of the present invention. The card reader 10 is installed on the top of the car 101, is connected with the elevator operation controller (not shown) through the communication bus, and moves up and down in the hoistway with the car. The IC card 20 is respectively fixedly installed on the inner wall of the shaft of each floor station, and the height difference between the installation position of the IC card of each floor station and the ground of the corresponding floor station is the same. Wherein, the IC card 20 is a passive IC card, and each IC card 20 has a unique identification number; the card reader 10 is a non-contact card reader. In this way, when the elevator car runs until the IC card 20 is within the effective range of the card reader 10...

The invention relates to an identification device of elevator floor stops, comprising at least one IC card and a card reader, wherein the IC cards are arranged in the designated positions of all floors of the inner wall of an elevator well road; and the card reader is installed on a carriage and is electrically connected with an elevator operating controller by a communicating bus. Compared with the prior art, the identification device of elevator floor stops is used for completely eliminating error floor failure for effectively enhancing the safety of elevator operation.
Description
technical field [0001] The invention belongs to the field of elevator control, in particular to an elevator floor identification device. Background technique [0002] Elevator is an indispensable vertical lift transportation device in people's daily life. The operation of the elevator is to move from one floor to another in the vertical direction. Therefore, the elevator control device needs to obtain the information of the current position of the elevator car, that is, which floor the elevator car is at. If the control device misidentifies the position of the car or the current landing, that is, a floor fault occurs, it may cause the following problems: (1) the elevator cannot run to the correct landing; (2) when the elevator runs to the end station, due to The running speed is too high and rushes out of the limit position, resulting in accidents of rushing to the top or squatting at the bottom; (3) The elevator cannot be accurately leveled. It can be seen that the fault ...
