Problems solved by technology

Some functional units have very strict timing when they are turned on and off. If the timing is disordered, the electronic components inside these functional units will be burned or logic failures will occur.
However, in the prior art, there are sudden power outages, which are called illegal power outages, such as illegal power outages caused by disconnection of mains power supply, illegal power outages caused by users’ irregular plugging and unplugging.
These illegal power cuts will cause damage to the above functional units, resulting in high failure rates and short service life of electronic equipment

Abstract

An embodiment of the invention discloses electronic equipment and a signal processing method. The electronic equipment comprises a functional part, a power supply circuit, a controller and a capacitor, wherein the power supply circuit is connected with the functional part and used for providing a power supply for the functional part; the controller is connected with the functional part and the power supply circuit, and is used for generating an outage command when illegal outage is detected and transmitting the outage command to the functional part; the capacitor is connected with the power supply circuit and is used for supplying electric power to the functional part through at least part of the power supply circuit after illegal outage, so that the functional part completes preset closing operation within the power supply time of the capacitor after the outage command is received.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device and a signal processing method. Background technique [0002] At present, with the development of electronic technology, more and more functional components are integrated on electronic equipment, and the functions realized are becoming more and more powerful. Some functional units have very strict timing when they are turned on and off. If the timing is disordered, the electronic components inside these functional units will be burned or logic failures will occur. However, in the prior art, there are sudden power outages, which are called illegal power outages, such as illegal power outages caused by disconnection of mains power supply, illegal power outages caused by users' irregular plugging and unplugging. These illegal power cuts will cause damage to the above-mentioned functional units, resulting in high failure rates and short service life of elec...
