摘要 |
In remote control operating systems with transmission of data between a central station and a plurality of sub-stations (US1...USn), spontaneous announcements have to be transmitted from these sub-stations, preferably after an interrogation, to the central station. The aim is to obtain a reliable interrogation after a short period of time from all the sub-stations on the presence or spontaneous announcements with the successive and addressed interrogation of the sub-stations having set spontaneous announcements. After the collective call from the central station, a switch on-switch off of all sub-stations of the series and according to the transmission level is achieved within a short time, to which only the sub-stations (US3) having a spontaneous announcement do not react. The central station interpretes the transitional pulses resulting from the switch on-switch on of the transmission level as an addressed interrogation.
