Design and develop a network monitor switch which is based on Ethernet communication. The design uses W5500 chip to realize communication with remote controller via Ethernet

and uses MAX1692 chip to achieve function of power supply of monitor switch and driver and control of actuator

uses Hall current sensor and voltage sensor for state monitoring of device to be controlled

and upload data to remote controller through Ethernet. The whole system has the advantages of high reliability

strong anti-interference performance

convenient to operation and flexible networking.
