The invention relates to an elevator driving record system and method, in particular to an elevator driving record technology which can be used as a basis for clarifying the maintenance responsibility of the elevator and for updating the replacement data of the parts.

Today, elevator equipment has become an indispensable ride tool for entering and leaving the floor. Through the electromechanical control of the elevator equipment and the operation of the power transmission mechanism, the passengers can be carried through the elevator car and then reach the destination landing. In recent years, there have been some major accidents in elevators. The causes of such elevator accidents are mostly the common types of accidents such as steel rope slippage and brake brake failure. Specifically, when the cable is slipped on the sheave, the rotary encoder and the sheave do not rotate, and the cable is continuously displaced, so that the rotary encoder cannot synchronously sense the actual displacement of the cable, thereby causing the electromechanical control unit of the elevator equipment. Misjudgment, so that there is a certain degree of height difference between the compartment pedal and the floor of the landing floor of the arrival floor, so that when the person enters and exits the compartment, it is easier to cause the vehicle to fall into the compartment; or the injury from the compartment to the landing floor, etc.; If the brake fails, in serious cases, the landing door will open and the carriage will continue to burst upward, causing dangerous accidental casualties.
