    摘要: An elevator system (2) comprises an elevator car (4a-d) that is moveable within a hoistway (6a-d). The elevator car (4a-d) comprises a first wireless communication unit (12a-d). A controller (8a-d) is arranged to communicate with the elevator car (4a-d) , the controller (8a-d) comprising a second wireless communication unit (14a-d). The first and second wireless communication units (12a-d, 14a-d) are arranged to exchange elevator operational data using a wireless communication protocol. Each data symbol within a set of data symbols corresponding to the elevator operational data is modulated onto a plurality of orthogonal sub-carriers using an orthogonal frequency division multiplexing modulation scheme. The modulated plurality of orthogonal sub-carriers are transmitted between the first and second wireless communication units (12a-d, 14a-d) over a wireless interface (16a-d).

    摘要: A guidance mechanism for an elevator car is constructed and arranged to move along a lane defined at least in-part between two opposing first and second lane structures of a stationary structure. The guidance mechanism includes a first support structure supported by the first lane structure. The first support structure includes a first retainer face disposed between the elevator car and the first lane structure that substantially faces the first lane structure, and is spaced from the first lane structure. A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.

    摘要: A hybrid energy storage system for an elevator car includes a converter disposed on the elevator car and receives power from a power source and provides a first DC voltage to a first DC bus and a second DC voltage to a second DC bus, a first energy storage device connected to the converter receives the first DC voltage on the first DC bus, and a second energy storage device connected to the converter receives the second DC voltage on the second DC bus. The system also includes a first load connected to the first DC bus and a second DC bus, and a second load connected to the second DC bus. Power is provided from the first energy storage device to the first load under a first selected condition and power is supplied from the second energy storage device to the first load under second selected condition.
