Application of W5100 in the Remote Power Quality Monitoring Equipment

In view of the disadvantages of traditional power quality monitoring method such as poor real-time and multi- parameter test performances, this paper proposes a design scheme for on site and remote online monitoring on power quality by combining Ethernet access and energy collection technologies. Micro-controller STM32F103 and Ethernet con- troller chip WSlO0 are used for network construction to realize the remote communication between host computer and slave computer. The SPI bus interface mode is selected to ensure the data rate. The paper also introduces the WS100 driver, discusses UDP protocol in detail, and defines the work process of network communication. The tests show that the interface can realize the network transmission of UDP data and guarantee the real-time transmission of power parameters. The remote monitoring on power quality can also be realized through Internet accessed from host computer.
