Abstract:Ethernet is an ideal platform for constructing elevator monitoring system. A scheme of elevator monitoring system based on Ethernet was developed, in which TMS320LF2407A was used as master chip, RTL8019AS as Ethernet interface chip, and the monitoring interface based on LabVIEW. It takes a method for elevator monitoring system to use Ethernet technique. Keyword:Ethernet;Elevator;Monitoring;DSP;LabVIEW
