In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of a hypervisor-based code scan method, it is noted that the steps illustrated in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a flowchart of a code scanning method based on a hypervisor according to an embodiment of the present invention, where the code scanning method based on a hypervisor includes the following steps:
step S102, acquiring the current detection state of the wire controller, wherein the wire controller is used for displaying the two-dimensional code.
The wire controller can be used for acquiring real-time information of each unit in the air-conditioning multi-split system, generating a two-dimensional code based on the acquired real-time information of each unit, and displaying the generated two-dimensional code on a display screen of the wire controller. In the embodiment, the real-time information of each unit in the multi-split system can be conveniently acquired by a user or an air conditioner operator in real time, and the real-time performance of the acquired information is improved as the two-dimensional code is generated based on the real-time dynamic state of each unit.
And step S104, under the condition that the current detection state is determined to be the display adjustment state, adjusting the display brightness of the display screen of the line controller to obtain the adjusted display brightness.
Because the scanning success rate of two-dimensional code is relevant with the formation of image quality of two-dimensional code image on scanning the sign indicating number equipment, and outside light intensity change is bigger again in one day, and the formation of image quality of two-dimensional code is closely correlated with the difference of the display luminance of two-dimensional code and external light intensity again, so fixed luminance shows that the success rate that the two-dimensional code can make the user scan the two-dimensional code becomes unstable, influences user experience. Therefore, in this embodiment, the display brightness of the display screen can be adjusted to improve the code scanning success rate of the two-dimensional code.
And S106, under the adjusted display brightness, triggering code scanning equipment to execute code scanning operation on the two-dimensional code displayed in the display screen of the online controller.
Through the steps, the current detection state of the wire controller can be obtained, wherein the wire controller is used for displaying the two-dimensional code; under the condition that the current detection state is determined to be the display adjustment state, adjusting the display brightness of the display screen of the line controller to obtain the adjusted display brightness; and under the adjusted display brightness, triggering code scanning equipment to execute code scanning operation on the two-dimensional code displayed in the display screen of the online controller. Compared with the prior art that the line controller needs to be awakened manually when the two-dimensional code needs to be scanned, the display brightness of the two-dimensional code is fixed, and cannot be adjusted, so that the defect that the code scanning success rate is low is easily caused.
In an alternative embodiment, determining that the current detection state is the display adjustment state may include: determining a first distance of a user of the code scanning device relative to the code scanning device; and under the condition that the first distance is within a first preset distance range, determining that the current detection state of the wire controller is a display adjustment state, wherein the first preset distance range is the distance range between the code scanning device and a user when the user scans the two-dimensional code by using the code scanning device.
Specifically, determining a first distance of a user of the code scanning device relative to the code scanning device comprises: determining that the line controller enters a first detection state; a first distance sensor for controlling the line controller detects a second distance between the user and the line controller; acquiring a third distance between the code scanning equipment and the line controller; and taking the difference value between the second distance and the third distance as the first distance of the user of the code scanning device relative to the code scanning device.
It should be noted that, in the wired controller in the embodiment of the present invention, two sets of distance sensors are integrated, and the two sets of distance sensors can be used to detect a code scanning action of a user, where, in the embodiment of the present invention, the types of the distance sensors are not specifically limited and may include, but are not limited to: infrared inductor, ultrasonic sensor.
The code scanning device may include, but is not limited to: cell-phone, iPad, bar code scanner. In the embodiment of the present invention, a code scanning device is taken as an example of a mobile phone. For example, the distance L of the user from the line controller may be detected using one of two sets of distance sensors (i.e., the first distance sensor)u(i.e., the second distance) and obtaining the distance L between the mobile phone and the wire controllerp(i.e., the third distance), the first distance may be determined by the following equation: l isd＝Lu+Lp，LdI.e. the first distance. When the first distance L isdAt L3And L4(i.e., the first predetermined distance range) when the current detection state of the line controller is within the two-dimensional code display adjustment state, that is, the current detection state of the line controller is determined to be the display adjustment state. In addition, L is3When the user scans the two-dimensional code, the distance between the mobile phone and the body of the user is the closest; l is4The distance between the mobile phone and the body of the user is farthest when the user scans the two-dimensional code. L is3、L4Values can be obtained experimentally.
In an alternative embodiment, determining that the wireless device enters the first detection state may include: a second distance sensor of the control wire controller detects a third distance between the wire controller and the code scanning device; and under the condition that the third distance is in a second preset range, determining that the line controller enters a first detection state, wherein the second preset range is the distance range between the code scanning equipment and the line controller when a user scans the two-dimensional code by using the code scanning equipment.
For example, the distance L of the user from the line controller may be detected using the other one of the two sets of distance sensors (i.e., the second distance sensor)p(i.e., the third distance) when the distance sensor of the other set detects the distance L between the mobile phone and the line controllerpAt L1And L2(i.e., the first predetermined distance range) when the current sensor is in the first detection state, wherein L is1When the two-dimensional code is scanned for a user, the distance between the mobile phone and the wire controller is the nearest distance; l is2And when the user scans the two-dimensional code, the mobile phone is farthest from the line controller. L is1And L2The numerical value of (A) can be obtained by experiment. It should be noted that the another distance sensor set is disposed near the display screen of the line controller, and may be used to detect the approach of the mobile phone above the line controller.
In the above embodiment, not only can the code scanning action of the user be effectively detected by using the two groups of distance sensors, but also the probability that the display screen of the line controller is mistakenly awakened is reduced, and the user experience is improved.
In an alternative embodiment, in step S104, adjusting the display brightness of the display screen of the line controller may include: acquiring the ambient illumination intensity by using a light sensor of the line controller; the method comprises the steps of obtaining preset illumination intensity required by code scanning equipment when the code scanning equipment scans a two-dimensional code, wherein the preset illumination intensity is the illumination intensity when the code scanning success rate exceeds a preset numerical value when the code scanning equipment scans the two-dimensional code; the display brightness of the display screen of the line controller is adjusted based on the ambient light intensity and the predetermined light intensity.
Specifically, adjusting the display brightness of the display screen of the line controller based on the ambient light intensity and the predetermined light intensity includes: on the basis of the ambient illumination intensity and the preset illumination intensity, the display brightness of the display screen of the line controller is adjusted through a preset formula, wherein the preset formula is as follows: o isL＝OS+OdWherein O isLFor adjusted display brightness, OSTo the intensity of ambient light, OdIs the difference between the predetermined illumination intensity and the ambient illumination intensity.
Wherein, there is a predetermined relationship between the difference and the ambient light intensity, wherein the predetermined relationship is a second formula:
a. n and b are illumination intensity adjustment values.
For example,activating the light sensor to obtain the environmental illumination intensity O when entering the wire controller of the two-dimensional code display regulation stateS. The wire controller adjusts the display brightness O of the display screenL，OL＝OS+Od。OdWhen the user scans the two-dimensional code most easily, the difference value between the brightness of the display screen and the ambient light intensity has the following relationship with the ambient light intensity:
the values of a, n, and b can be obtained from experimental data. Finally, the available formula of the wire controller for controlling the display brightness of the display screen is as follows:
meanwhile, the imaging quality of the two-dimensional code is related to the display brightness of the two-dimensional code and the capability of a camera of a mobile phone of a user for acquiring images, so that different mobile phones can have different O valuesdValue, O of the above formuladThe values are those that satisfy most users. Aiming at a user in a special condition, the wire controller can continuously detect the code scanning action of the user when entering a display adjustment state, if the code scanning action lasts for a time T, the code scanning action of the user is not successful, the display brightness needs to be adjusted, and at the moment, the wire controller can gradually adjust the display brightness from small to large according to the value b in the formula until the scanning action is finished.
That is, in step S104, triggering the code scanning device to perform the code scanning operation on the two-dimensional code displayed in the display screen of the line controller may include: detecting the code scanning operation to obtain a detection result, and counting the duration of the code scanning operation; and determining that the duration exceeds the preset duration, and continuously adjusting the adjusted display brightness until the detection result shows that the code scanning operation is finished.
And continuously adjusting the adjusted display brightness by adjusting b in the illumination intensity adjustment value.
An alternative embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

In the embodiment, the time when the line controller needs to enter the brightness adjustment is accurately determined, and the code scanning success rate is improved.
