Dial switch array-based bypass power supply time sequence control circuit

Abstract

The invention relates to a bypass power supply time sequence control circuit based on a dial switch array. The circuit is provided with an array coding module, a switch voltage stabilization chip and a single-chip microcomputer. Wherein the array coding module and the switch voltage stabilizing chip are both connected with the single chip microcomputer; the single-chip microcomputer is used for controlling the on time and the off time of the switch voltage stabilization chip according to the level signal output by the array coding module, so that the power-on time can be accurately controlled while the power-on time sequence function is accurately controlled.

Description

technical field [0001] The invention relates to the technical field of timing control circuit design, in particular to a bypass power supply timing control circuit based on a dial switch array. Background technique [0002] At present, most of the power-on timing and time control circuits are implemented by using an independent clock chip or a built-in timer in the microcontroller to generate a timing interrupt, and the timing interrupt triggers the IO port of the microcontroller to control the external electronic switch chip to realize the power on and off. off. This method is more convenient to control a punctual timing power-on, but it is impossible to control the power-on sequence and power-on time at the same time. [0003] Therefore, it is an urgent problem for those skilled in the art to conveniently and quickly set the cycle power-on sequence and power-on time of the bypass power supply. Contents of the invention [0004] In order to solve the above-mentioned pro...
