Abstract
The invention discloses an elevator cable satisfying an RS485/232 communication function. The elevator cable comprises a flat outer sheath and a cable core disposed in the middle of the flat outer sheath. An RS485 communication cable and an RS232 communication cable are respectively disposed on two sides of the cable core. Each of the RS485 communication cable and the RS232 communication cable is a double-stranded communication cable. The stranding directions of the RS485 communication cable and the RS232 communication cable are opposite. A first shielding layer is disposed in the RS485 communication cable. A second shielding layer is disposed in the RS232 communication cable. The elevator cable has the advantages that the cable number in a shaft is reduced, and normal operation of an elevator is guaranteed; in addition, the stranding directions of the RS485 communication cable and the RS232 communication cable are opposite, so that the bending resistance of the elevator cable can be guaranteed, signal interference between the RS485 communication cable and the RS232 communication cable and the cable core can be prevented by the shielding layers, and normal communication can be guaranteed.
