Description

Independent controlled power supply device and independent power supply control method Technical Field The invention relates to the technical field of power supply control equipment, in particular to a power supply device capable of automatically identifying power demand and independently controlling on-off and a control method. Background Most of power supply equipment such as an existing patch board, a power supply socket and a charging station adopt a control mode of integral power supply and integral on-off, and cannot independently control a single output port. Even if the device is empty (e.g., the charger is plugged in only and not charged), the output port continues to be powered, resulting in: energy waste, namely accumulating no-load power consumption of the charger to cause unnecessary electric energy loss; Aging of components, namely accelerating aging of internal elements after long-term energization, and shortening the service life; The temperature rises, namely heating still exists in an idle state, and potential safety hazards exist; and the fire risk is that the long-term power-on can cause fire accidents such as overheat, short circuit and the like. The equipment with the sub-control function only supports manual key or remote switch control, and cannot realize energy-saving on-off according to the fact that the load is not automatic, and a user needs to manually operate, so that the equipment is inconvenient to use and easy to forget. In addition, the prior art generally has the problem of limited protection scope, and is easy to avoid by competitors through changing detection modes, control logics or structural forms. The inventors of the present invention have realized that a core drawback of the prior art is the lack of a judgment of the essential problem of whether the device really needs to be powered up, resulting in a large amount of unnecessary no-load power up. The invention has the core innovation of the technical concept of 'independent power consumption requirement detection for each output port, power on when power is required and power off when power is not required', and is not a specific circuit form for realizing the concept. According to the practical application, a person skilled in the art can adopt various detection principles, control algorithms and circuit architectures to achieve the same technical effects. Disclosure of Invention The invention aims to overcome the defects of the prior art, provides an independent controlled power supply device and an independent power supply control method, realizes independent intelligent control of each output port, namely automatic power-on when power is required, automatic power-off when no power is required, eliminates no-load power consumption, and improves safety and convenience.

Further, the electricity demand detection includes, but is not limited to, load electricity utilization state detection, device communication detection, device access detection, and electricity demand detection. According to the practical application, a person skilled in the art can realize accurate identification of electricity demand in a single mode or in a combination of multiple modes. Further, the load power utilization state detection comprises at least one of current detection, voltage detection, power detection and impedance detection, the equipment communication detection comprises at least one of establishing communication connection with equipment, receiving equipment power utilization requests and identifying equipment types, and the equipment access detection comprises at least one of mechanical triggering detection, infrared induction detection and capacitance induction detection.
