| Zusammenfassung: | In order to make it possible to transmit and receive information between terminals and to reduce number of wires used for an elevator in a building in an elevator system by realizing the transmitting and receiving of information through wireless even if a very weak radio wave having a narrow communicable range is used, an elevator control unit, a car terminal and floor terminals are individually provided with short distant wireless transmitting/receiving units having a communicable range of nearly 2-floor distance (5 to 6 m) using very weak radio wave, and the radio wave is received and transmitted between the wireless transmitting/receiving units located within the communicable range to transmit information by a relaying method of sequentially transferring the information from the terminal to the terminal. |
