Automatic transfer switch controller voltage acquisition device and control method

Abstract

The invention relates to a voltage acquisition device and a control method of a multiple voltage grade automatic transfer switch controller. The automatic transfer switch controller comprises six paths of voltage acquisition circuits, wherein each path of the voltage acquisition circuits mainly comprises double paths of multiple voltage grade signal acquisition circuits, a controller working power supply circuit, a controller drive circuit and the like. A microcontroller (MCU) controls the voltage signal acquisition circuits to collect voltage signals, and actions are completed by connecting an I / O port of the MCU to display, using a keyboard input circuit to perform input and output operations and using a switching circuit drive system. The controller uses the MCU-I / O port which judges electrical level changes to collect, and preliminary acquisition of two paths of power supply voltage signals are preformed by using the same six paths of voltage acquisition circuits. Accordingly, the voltage acquisition device and the control method of the multiple voltage grade automatic transfer switch controller are convenient and reliable to adjust, and simple in structure, save materials, overcome the difficulty that a traditional automatic transfer switch can not be simultaneously used on voltage grades above one, and bring convenience for users to use and adjust.
