Abstract
Various machines and apparatus equipped in an unattendet remote controlled station are associated with contact means through which the remote supervisory control for the operation of these machines and apparatus is carried out to a master station. Contact information provided by the individual contact means is assigned with an indication input type determined by a setting circuit provided for each of the indication input types. The contact information assigned any one of indication input types is stored in a memory circuit having a predetermined memory and holding function which is provided for each of the indication input types. Outputs from the memory circuits are ORed and thereafter converted into a predetermined transmission format, which is transmitted to the master station, thus completing an indication input signal processing. A predetermined number of the contact information is ganged into groups and all of the above-mentioned processes are carried out by processing the groups on a time division basis.
