Secondary clock system with central control unit with clock time transmitter for use in e.g. sea going ships

摘要

The secondary clock system consists of a central control unit (1), which contains a clock time transmitter, for the purpose of controlling several analogue secondary clocks (4). A series or a parallel connected data line system (3) is used for transmitting the time data to the secondary clocks. The secondary clocks contain an intelligent microprocessor electronic assembly (5), for data decoding and operational control, which determines the position of the gear drive and with this the position of the clock hands, with the smallest possible step angle of the drive, most probably the second step angle or the minute step angle.
