Research And Realization Of Remote Channel Monitoring Device Based On Ethernet

Based on remote monitoring system of channel key technologies involved in the study. Mainly based on the principle of ac sample level algorithm, Based on the test cycle had zero frequency measurement method, At level measurement and frequency measurement using digital filtering technology, and the monitoring system of the use of network protocol stack. This issue designed by electric power remote channel monitoring system uses the "embedded Internet" technology, digital signal processing technology, high-speed data acquisition technology and other advanced technology to realize the power telecontrol channel real-time monitoring. System can be collected and remote signal level and frequency, and the measurement of the complete. System can provide based on TCP/IP protocol of the hardware connection and transmission, which solved the information transmission remote real-time and reliability problems.
