In view of the problems in the background art, the inventor of the present invention has found, after studying the prior art, that in the prior art, the gain adjustment for the infrared signal is performed in a step-by-step approximation manner, that is, the MCU assigns a value of 0 to the operational amplifier, and the operational amplifier outputs the currently adjusted gainInfrared signals are converted by an ADC (analog to digital converter), whether the currently adjusted infrared signals accord with target signal strength is compared, if not, the operational amplifier is assigned with 1 to be readjusted, and so on until the target signal strength is met, so that the gain adjustment of one infrared signal usually needs 2m(m is a natural number) times, and the time is long.
In view of this, an embodiment of the present application provides a gain adjustment method, an apparatus, a device, and a storage medium for an infrared touch screen, where in a process of performing gain adjustment on a current infrared signal, since a preset gain value corresponding to the current infrared signal is pre-stored in a gain adjustment device, the preset gain value can be called, and the current infrared signal can be directly adjusted through the preset gain value, so that the current signal intensity of the current infrared signal is equal to a target signal intensity.
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Referring to fig. 2, a schematic flow chart of a first embodiment of a method for adjusting gain of an infrared touch screen in an embodiment of the present application is shown.
In this embodiment, a method for adjusting gain of an infrared touch screen is applied to a device for adjusting gain of an infrared touch screen, and the method includes:
It should be noted that, when the gain adjustment device is in the adjustment state, the gain adjustment device may perform gain adjustment on the current infrared signal in the scanning optical path, so that the current infrared signal and the signal identifier of the current infrared signal are obtained first.
It is understood that the type of the signal identifier may be various, for example, a mathematical number of 1, 2, 3, etc., or a letter number of A, B, C, etc., and those skilled in the art may set the type according to their own needs, which is not limited and described herein.
The current infrared signal in the scanning optical path is changed, for example, when the infrared signal 1 is in the scanning optical path, the infrared signal 1 is the current infrared signal, after the gain adjustment of the infrared signal 1 is completed, the infrared signal 2 is input into the scanning optical path, the current infrared signal 2 is the current infrared signal, and so on, the current infrared signal is taken as the current infrared signal for the infrared signal currently located in the scanning optical path each time, and then the gain adjustment is performed on the current infrared signal.
After the current infrared signal and the signal identifier of the current infrared signal are acquired, the preset corresponding relationship between the infrared identifier and the preset gain value is stored in the gain adjusting device, so that the preset gain value corresponding to the infrared identifier can be directly determined according to the preset corresponding relationship.
And 203, adjusting the current infrared signal according to the preset gain value to enable the current signal intensity of the current infrared signal to be equal to the target signal intensity.
After the preset gain value corresponding to the current infrared signal is obtained, the current infrared signal can be directly adjusted through the preset gain value, so that the current signal intensity of the current infrared signal is equal to the target signal intensity.
The gain adjustment method of the infrared touch screen is applied to a gain adjustment device of the infrared touch screen, when the gain adjustment device executes the method, firstly, when the gain adjustment device is in an adjustment state, a current infrared signal located on a scanning light path and a signal identifier of the current infrared signal are obtained, then, according to the signal identifier, a preset gain value corresponding to the signal identifier is obtained based on a preset corresponding relation between the locally stored signal identifier and the preset gain value, and then, after the current infrared signal is adjusted according to the preset gain value, the current signal intensity of the current infrared signal can be equal to the target signal intensity. Therefore, in the process of gain adjustment of the current infrared signal, the preset gain value corresponding to the current infrared signal is stored in the gain adjustment device in advance, so that the preset gain value can be directly called, the current infrared signal can be rapidly adjusted through the preset gain value, and compared with the existing mode of gradually approaching to adjust the infrared signal, the time consumption is short, so that the technical problems that in the prior art, the time consumption for gain adjustment of the infrared signal is long, and the requirement for rapid adjustment of the infrared touch screen after environmental change is not met are solved.
The above is a first embodiment of a method for adjusting gain of an infrared touch screen provided in the embodiment of the present application, and the following is a second embodiment of a method for adjusting gain of an infrared touch screen provided in the embodiment of the present application.
Referring to fig. 3, a flowchart of a second embodiment of a method for adjusting gain of an infrared touch screen in an embodiment of the present application is shown.
In this embodiment, a method for adjusting gain of an infrared touch screen is applied to a device for adjusting gain of an infrared touch screen, and the method includes:
It should be noted that the description of step 301 is the same as the description of step 201 in the first embodiment, and reference may be specifically made to the description of step 201, which is not described herein again.
Further, in order to save the time of gain adjustment, after the current infrared signal is acquired and before the current infrared signal is gain adjusted, it is determined whether the current signal strength and the target signal strength are equal, and if the current signal strength and the target signal strength are not equal, the gain adjustment is performed.
And 303, acquiring a preset gain value corresponding to the signal identifier based on the preset corresponding relation between the locally stored infrared identifier and the preset gain value according to the signal identifier.
In this embodiment, the configuration process for the preset corresponding relationship may include:
when the gain adjusting device is in a configuration state, acquiring the target signal intensity, the signal identifier of the current infrared signal and the current signal intensity;
performing gain adjustment on the current infrared signal based on the target signal intensity;
when the current signal intensity is adjusted to be equal to the target signal intensity, taking the corresponding adjustment gain as a preset gain value;
and constructing a preset corresponding relation according to the signal identification and the preset gain value.
It can be understood that, in the use process of the gain adjustment apparatus, in order to make the adjusted signal more fit to the actual situation, the preset gain value corresponding to the current infrared signal is further updated, specifically:
and reconfiguring the preset corresponding relation every other preset time period.
The obtaining of the working state of the gain adjustment device may be achieved by obtaining a control signal of the MCU to the gain adjustment device, for example, when the MCU sends a high-level control signal to the gain adjustment device, the gain adjustment state at this time is an adjustment state (i.e., a preset gain value, a read state of a preset correspondence); when the MCU sends a low level control signal to the gain adjustment device, the gain adjustment state at this time is a configuration state (i.e. a preset gain value, a write state of a preset corresponding relation)
And 304, adjusting the current infrared signal according to the preset gain value, so that the current signal intensity of the current infrared signal is equal to the target signal intensity.
It should be noted that the description of step 304 is the same as the description of step 203 in the first embodiment, and reference may be specifically made to the description of step 203, which is not repeated herein.
And 305, reconfiguring the preset corresponding relation every preset time period.
It can be understood that, in the use process of the infrared touch screen, the preset gain value corresponding to the current infrared signal may change, and in order that the current infrared signal after the gain adjustment meets the requirement, the preset corresponding relationship is reconfigured at intervals of a preset time period.
The gain adjustment method of the infrared touch screen is applied to a gain adjustment device of the infrared touch screen, when the gain adjustment device executes the method, firstly, when the gain adjustment device is in an adjustment state, a current infrared signal located on a scanning light path and a signal identifier of the current infrared signal are obtained, then, according to the signal identifier, a preset gain value corresponding to the signal identifier is obtained based on a preset corresponding relation between the locally stored signal identifier and the preset gain value, and then, after the current infrared signal is adjusted according to the preset gain value, the current signal intensity of the current infrared signal can be equal to the target signal intensity. Therefore, in the process of gain adjustment of the current infrared signal, the preset gain value corresponding to the current infrared signal is stored in the gain adjustment device in advance, so that the preset gain value can be directly called, the current infrared signal can be rapidly adjusted through the preset gain value, and compared with the existing mode of gradually approaching to adjust the infrared signal, the time consumption is short, so that the technical problems that in the prior art, the time consumption for gain adjustment of the infrared signal is long, and the requirement for rapid adjustment of the infrared touch screen after environmental change is not met are solved.
The second embodiment of the method for adjusting the gain of the infrared touch screen provided in the embodiment of the present application is as described above, and the following is an embodiment of the method for adjusting the gain of the infrared touch screen provided in the embodiment of the present application, please refer to fig. 4.

and constructing a preset corresponding relation according to the signal identification and the preset gain value.
For easy understanding, in the present embodiment, the working flow of the gain adjustment device implemented in the present embodiment is described with reference to fig. 5, assuming that the infrared touch screen has n in total1The infrared ray amplifying circuit comprises n paths of infrared rays, and the specific flow is as follows:
1. configuration state of the automatic gain device: the DAC of the MCU outputs a target value, and R/W is set high;
2. when a first group of infrared signals enter the automatic gain device, AGC (automatic gain adjustment) is realized inside the automatic gain device until the output VOUT is consistent with the target value DAC, after the adjustment is finished, the AGC value is stored inside the automatic gain device, and the MCU does not participate in the control;
3. the rising edge of the clock signal CLK moves the stored position to the next bit to be stored with a set of AGC values;
4. when a second group of infrared signals enter the automatic gain device, AGC (automatic gain adjustment) is realized inside the automatic gain device until the output VOUT is consistent with the target value DAC, and after the adjustment is finished, an AGC value is stored inside the automatic gain device;
5. repeating the steps 3 and 4 for n1/n times until all infrared rays of the touch screen are adjusted;
6. adjustment state of the automatic gain device: R/W is set low;
7. a rising edge of a clock signal CLK calls a first set of AGC values of a memory;
8. a first group of infrared signals enter the automatic gain device;
9. amplifying the amplification factor called by the memory;
10. repeating the above steps from 7 to 9 times until all the infrared ray applications are completed;
the above 1 to 5 are configuration time of the signal, the above 6 to 10 are adjustment time of the signal, the steps of 6 to 10 are repeated in the using process of the infrared touch screen, each time is a period, and the steps of 1 to 5 are carried out every other one or more periods to adjust the AGC value.
As can be seen from the above, the infrared touch screen has n1When the amplification circuit has n paths, the time of each signal period of each infrared ray is T, and the adjustment time of the whole signal is n1T/n. The infrared ray, the amplifying circuit and the signal period are the same, and the required time is 2 by adopting the existing gain adjustment methodmTn1It is obvious that the gain adjusting device in this embodiment can significantly shorten the gain adjusting time, and only 1/2 is usedmTherefore, the method can realize rapid signal adjustment (within a few milliseconds), adapt to environment change and the like, such as touch screen shaking and blackboard push-pull problem (generally in the order of seconds) in a classroom.

Therefore, in the process of gain adjustment of the current infrared signal, the preset gain value corresponding to the current infrared signal is stored in the gain adjustment device in advance, so that the preset gain value can be directly called, the current infrared signal can be rapidly adjusted through the preset gain value, and compared with the existing mode of gradually approaching to adjust the infrared signal, the time consumption is short, so that the technical problems that in the prior art, the time consumption for gain adjustment of the infrared signal is long, and the requirement for rapid adjustment of the infrared touch screen after environmental change is not met are solved.
