Intelligent power-supply control device and operating method thereof

Abstract

The invention relates to an intelligent power-supply control device and an operating method thereof, which are suitable to be applied to the intelligent control and energy-saving technique for office appliances and home appliances. The device comprises an alternating-current power supply circuit, a power supply startup circuit, a direct-current voltage-stabilizing circuit, a startup control circuit, a current detection circuit and a fax-machine start-up circuit; the device can automatically complete a right on/off order of a host of a computer and external devices of the computer, thereby avoiding the occurrence of a situation that the host of the computer is damaged or data is lost caused by an impulse current generated when the external devices of the computer are turned on and off; the fax-machine startup circuit can automatically start a power supply of a fax machine in the process of receiving/sending faxes, thereby solving the problem that the fax machine is electrified and in a standby waiting state in the whole day; and the device has master control startup, self-control startup and fax-machines startup functions, thereby facilitating the selection of number, type and operating mode of application equipment; and through the setting of intelligent control with master control detection and self-control detection functions, the standby power losses of office appliances, home appliances and the device are equal to zero.

Description

technical field [0001] The invention relates to an intelligent power control device and a working method thereof which are suitable for the intelligent control and power saving technology of office appliances and household appliances. Background technique [0002] Now the use of office appliances and household appliances is very popular. The correct use of office appliances and household appliances and how to save energy have become a focus of people's attention. Energy conservation and environmental protection have become the theme of people's lives and work. When using computers and computer peripheral devices (monitors, speakers, printers, modems, etc.), according to the operating requirements, you must first start the external devices used by the computer, and then start the computer host. Turn off the external devices used, so as not to damage the main computer or cause data loss due to the inrush current generated by the external devices when the computer is turned on / ...

AI Technical Summary

Problems solved by technology

Fax machines are usually powered on around the clock and in a standby waiting state. Long-term power-on status not only affects the service life of the fax machine, but also causes waste of electric energy, temperature rise, component aging, complete machine damage, and fire hazards.

When watching TV programs with TV sets and set-top boxes, it often occurs that the remote control is used to turn off the TV after watching the TV, but the power switch of the TV or set-top boxes is not turned off or the power plug is unplugged, resulting in long-term standby and wasting power energy

The damage rate of office appliances or household appliances due to misoperation is also very high, which brings unnecessary troubles or irreparable losses to users.

At the same time, the standby status of office appliances and household appliances is also very common. In actual use, people often forget to turn off the power switch of office ap
