The invention belongs to the field of elevators, and relates to a system and method suitable for wireless energy and signal transmission of an elevator car. The system comprises an elevator shaft andthe elevator car which is movably arranged in the elevator shaft, and further comprises a primary side which is arranged on a wall of the elevator shaft, and a secondary side which is arranged on theelevator car, wherein the primary side is a guide rail type coil and is arranged along a movement direction of the elevator car; the secondary side which is an S-shaped soft magnet coil is matched with the primary side; the primary side is arranged on an inner side of the wall of the elevator shaft through a first mounting bracket; and a relation between the elevator car load and the input currentis established, so as to judge whether the elevator car is closed or not by detecting the input current. By adopting wireless power supply and wireless communication technology, wireless signal transmission based on wireless energy identification is achieved, signal transmission is judged according to the input current waveform of wireless energy transmission, and wireless power supply and wireless operation of an elevator car are achieved.
Description
technical field [0001] The invention belongs to the field of elevators, and relates to a system and method suitable for wireless energy and signal transmission of elevator cars Background technique [0002] As a kind of electromechanical equipment that moves vertically, the elevator currently uses a dragging cable to power the elevator car. The accompanying cable goes up and down with the elevator car, which has the disadvantages of low efficiency and high maintenance costs. Especially in super high-rise buildings and high-speed elevators, if the elevator running speed is too high or the free suspension length is too long, it will increase the carrying load of the accompanying cables, and there will be safety risks such as wear, accelerated aging, and unsafe exposure, which will greatly reduce the reliability of the elevator. performance and operational efficiency. [0003] In addition to the power transmission function, the conformal cable of the elevator car also involves...
