Based on the system analysis of network-based remote monitoring, configuration king software characteristics and the working process of air compressor, a low-cost solution for remote monitoring of air compressor using industrial control machine combined with Ethernet network technology is proposed. Introduction in the industrial environment, using industrial configuration software - Configuration King software, using Ethernet network based PC data acquisition method and parameter method to realize the fault diagnosis of air compressor, a remote online real-time monitoring system based on Ethernet network air compressor station is designed, remote automatic monitoring and fault diagnosis of the operating status and operation process of the air compressor through Ethernet, realizing the integration of unattended, remote monitoring and management control.
