ELEVATOR CONTROL TRANSMISSION SYSTEM

摘要

A transmission connection apparatus (11) is connected to a control transmission system that cyclically serial-transmits control information of an elevator, and also connected to an information transmission system that serial-transmits display-setting information of the elevator. A transmission control circuit (14) exchanges and transfers the control and display-setting information to the control and information transmission systems. The display-setting information, when transferred to the information transmission system, is transferred via an information transmission interface circuit (15). This can reduce the load of a control information processing apparatus that controls the transmission operations of the control and information transmission systems.
