Description

Technical Field

[0001] The present invention relates to the technical field of power adapters, and in particular to an intelligent control method for a power adapter. Background Art

[0002] A power adapter is a device that converts mains electricity into a specific voltage and current to suit the needs of electronic devices. One end of it is connected to the mains socket and the other end is connected to the device. Through internal circuit conversion, it provides stable and safe power for mobile phones, laptops, etc. High-quality power adapters have functions such as overvoltage and overcurrent protection to ensure the safety of equipment and users.

[0003] The invention patent with application number 202110937100.7 discloses a method for starting electrical equipment, which is characterized in that it includes: after the adapter is powered on, obtaining the power output value in the adapter; judging whether the power output value reaches a preset range, wherein the preset range is determined according to the rated value of the adapter: when the power output value does not reach the preset range, delaying the start-up of the electrical equipment powered by the adapter, so that the electrical equipment and the adapter are started at different peaks to avoid the simultaneous occurrence of the startup peak of the adapter and the startup peak of the electrical equipment; the delayed start-up of the electrical equipment includes: obtaining the power-on time corresponding to the adapter; judging whether the power-on time reaches the preset time; when the power-on time reaches the preset time, starting the electrical equipment corresponding to the adapter.

[0004] This application aims to solve the problem that "in an environment where the adapter drives a high-power load, starting the high-power load at the same time as the adapter will cause the startup spike of the adapter and the instantaneous spike of the high-power load to be superimposed, thereby making the reverse pressure at the moment of adapter startup too large, which may be close to the conduction limit value of the MOS tube, affecting the safety and reliability of the adapter."

[0005] However, when the electrical equipment is connected to the power supply through the power adapter, the instability of the power supply voltage directly affects the operating frequency of the power adapter. Currently, the power adapter can adaptively adjust the voltage according to the change of the power supply voltage. This kind of adjustment causes the performance of the power adapter to be fatigued and only has the effect of adjusting the voltage. For the electrical equipment, there is no energy-saving maintenance effect. Summary of the invention

[0006] In view of the above shortcomings of the prior art, the present invention provides an intelligent control method for a power adapter, which solves the technical problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

If formula (2) holds, the power adapter controls the operation. If formula (2) does not hold, the decision operation of whether to control the operation of the power adapter connected to the power-consuming device is refreshed.

[0022] Furthermore, the power consumption mode determination value of the electric device is provided with two groups, which are respectively applied to the determination of the high power consumption mode and the low power consumption mode of the electric device;

[0023] The power consumption mode of the electric device is determined according to:

[0024]

[0025] Where: P is the average power of the electrical equipment;

[0026] in, Table pair Based on the average power P of the electrical equipment and the power consumption mode determination value of the electrical equipment, it is determined whether the current electrical equipment is in high power consumption mode or low power consumption mode.

[0027] Furthermore, the power adapter adjusts the voltage of the power supply connected to the power supply of the power consumer according to the rated power of the power consumer:

[0028] When the current power consumption mode of the power-consuming device is high power consumption mode, the target voltage of the power supply connected to the power-consuming device is

[0029] When the current power consumption mode of the power-consuming device is low power consumption mode, the target voltage of the power supply connected to the power-consuming device is

[0030] Where: P max , P min is the maximum rated power and minimum rated power of the electrical equipment; ε and θ are constants; I is the current current of the electrical equipment;

[0031] Among them, the constants ε and θ are both greater than zero and are set by the user.

[0032] Furthermore, the duration of voltage regulation performed by the power consumption mode recognition result when the power-consuming device is connected to the power supply does not exceed the time threshold corresponding to three operations of the sensor;

[0033] After the application of the power supply voltage adjustment result of the power-consuming device connected based on the power consumption mode recognition result is completed, the power adapter refresh runs once.

[0034] Furthermore, the power adapter operation message content includes: power adapter voltage adjustment result, power adapter voltage adjustment timestamp, power adapter voltage adjustment frequency, power adapter voltage adjustment range;

[0035] Among them, the power adapter operation message performs output operations based on the specified output cycle, the number of content groups contained in the power adapter operation message output each time is equal, and the same part of the content contained in the power adapter operation message outputted twice adjacently is not less than half of the message content in the single output power adapter operation message.

[0036] Furthermore, based on the power adapter operation message, it is analyzed whether there are security risks in the operation environment of the power-consuming equipment;

[0037] s1×(U MAX -U MIN)1<s2×(U MAX -U MIN )2<s3×(U MAX -U MIN )3;

[0038] Where: s1 is the voltage adjustment frequency of the power adapter in the first group of power adapter operation messages; (U MAX -U MIN )1 is the difference between the maximum regulation voltage and the minimum regulation voltage within the voltage regulation range of the power adapter in the first group of power adapter operation messages;

[0039] Among them, the application parameters in the above formula are the three sets of power adapter operation messages output most recently. If the above formula is established, it means that there are safety risks in the operation environment of the power equipment. Otherwise, it means that there are no safety risks in the operation environment of the power equipment.
