Application of Ethernet in Straddling Monorail Transportation System in Chongqing

Research purposes: The purposes were to apply Ethernet technology in monitoring system for power supply so as to improve automation level of power supply system for urban mass transit.Research methods:An introduction in details was given to the structure and features of power monitoring system for straddling monorail transportation in Chongqing,mainly to the system distribution,structure of communication system and software structrue of communication system of master station in control centre as well as the structure of automatic system in substation.The analysis was made of the causes for the problems of equipment in substation being out of service frequently and losing communication data packet,and the commissioning and tests were done to them repeatedly.Research results:Based on several experimental research,application of Ethernet in power monitoring system for straddling monorail transportation system in Chongqing was successful.Research conclusions:Based on successful application of Ethernet in power monitoring system for straddling monorail transportation system in Chongqing,it hoped Ethernet could be applied widely in monitoring system for urban mass transit in future.
