Abstract

The invention provides a voltage monitoring method and device, and the method comprises the steps of obtaining a current sampling voltage according to a preset sampling period, wherein the current sampling voltage is the input voltage of a to-be-detected module; comparing the current sampling voltage with a current threshold voltage, and outputting a detection result; and outputting a trigger signal matched with the detection result according to the detection result, so that the to-be-detected module makes a corresponding response. According to the voltage monitoring method provided by the invention, the input voltage can be compared with the threshold voltage, and the trigger signal corresponding to the comparison result is sent out, so that the to-be-detected module can respond in time under different startup and shutdown interval durations, and the problem of operation errors can be avoided in time.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a voltage monitoring method and device. Background technique [0002] With the rapid development of electronic technology, the concept of quality-oriented electronic equipment has become more and more popular. Good-quality equipment means that it can operate normally under various harsh and rare conditions. It is very difficult to ensure that the running response of the system works properly. [0003] At present, in order to ensure the normal operation of the equipment under the condition of fast switching on and off, a voltage detection module is installed on the total power supply module of the equipment, which is used to send a power-on reset signal to each control module after detecting that the total power supply reaches the power-on detection threshold , so that each control module can respond in time, and it is also used to send a power-off reset signal afte...
