| Abstract: | The INTRON-D digital intercom system is a sort of industrial communication equipment used widely in Baosteel.The operation principles for the system including signal conversion,transmission,switching,etc.are discussed.Through encoding the PCM(pulse code modulation),the system multi-modulates the PCM-encoded serial stream to form TDM(time division multiplex) signals.Then TDM signals are processed according to the data access principle of the control memory to strengthen channel utilization and reduce the transmission cost.In combination with debugging of the intercom system at the BNA Corporation,analysis of the system's application has been made,which could provide theoretical basis and reference for equipment maintenance and service quality elevation in future. |
