Design and Implementation of Visual Data Interaction Controller for Distribution Automation Terminal

In order to meet the requirements of debugging, maintenance, installation, joint debugging, and equipment inspection of distribution automation terminals, this paper designs a visual data interaction controller.The device adopts a modular design, mainly composed of MCU module, LCD display module, LED module, key operation module and serial communication module.The data interaction software uses an independent operating system for multitasking synchronous execution.The visual data interaction controller can realize the functions of data visualization, status query and modification, human-machine interaction of distribution automation terminal. It is an important channel for field operation and maintenance personnel to perceive status and functional maintenance of distribution automation terminal equipment, and can effectively improve the maintenance convenience of distribution automation terminal.
