The invention provides an elevator cable-free system adopting a serial communication technology. The elevator cable-free system comprises a control cabinet, a car roof maintenance box, a pit maintenance box and an operation box. The car roof maintenance box is installed on the top of an elevator car and is in serial wireless data communication with the control cabinet through the wireless communication module, and sending of control signals is achieved. An isolation terminal of the car roof maintenance box is connected with a busbar transmission device and used for transmitting switching value signals to a receiving device in the control cabinet to achieve monitoring of safety signals, the control cabinet is connected with the pit maintenance box, and the car roof maintenance box is connected with the operation box. The manufacturing and maintenance cost can be reduced; people trapping conditions caused by faults such as aging failure, short circuit and high-low voltage series connection of the traveling cable are avoided, and the failure rate of the elevator is reduced; the requirement on the technical level of maintenance personnel is reduced; and the attractiveness of the sightseeing elevator is improved.
