[0021] In order to make the objects, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in conjunction with the drawings.

[0022] It should be clear that the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. In the description of the present application, it should be understood that the terms "first", "second", "third" and the like are only used to distinguish similar objects, and do not necessarily describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The singular forms "a", "an" and "the" used in the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. The word "if" used herein can be interpreted as "when" or "when" or "in response to determining".

[0024] In addition, in the description of the present application, "multiple" means two or more, unless otherwise specified. The association between the objects described by "and / or" can exist in three ways, for example, A and / or B can represent the existence of A alone, the existence of A and B together, and the existence of B alone. The character " / " generally represents a "or" relationship between the associated objects before and after.

[0025] In order to better understand the technical solutions of the present application, the related application scenarios of the present application are introduced as follows.

[0026] The present application is applied to an infrared touch frame, also known as an infrared touch frame, which is provided with a plurality of infrared emission-receiving module groups on the frame body. Each infrared emission-receiving module group includes an infrared emission group and an infrared receiving group. The number of infrared emitters in the infrared emission group is the same as that of infrared receivers in the infrared receiving group. The infrared light emitted by the infrared emission group forms an infrared matrix on the frame surface of the infrared touch frame. The infrared receiving group can locate the position of the touch operation according to whether the infrared light emitted by the corresponding infrared emission group is received, and then realize human-computer interaction according to the located position.

[0027] Among them, since the electrical signal reflecting the infrared light detection result output by the infrared receiving group is a weak electrical signal, an amplification circuit is needed to amplify the electrical signal output by the infrared receiving group. Therefore, the infrared receiving group and the amplification circuit form an infrared receiving signal amplification circuit, and the RAGC (red infrared receiving gain gear) of the infrared receiving signal amplification circuit affects the amplification multiple of the infrared receiving signal amplification circuit. However, since the capacitance parameters of the infrared receiving signal amplification circuits with different RAGC may be different, and the amount of electrical signals actually accumulated by the capacitances of the infrared receiving signal amplification circuits with different RAGC is also different, the same discharge time will cause part of the amplification coupling capacitance to be unable to be completely discharged, affecting the accuracy of the output signal of the infrared receiving signal amplification circuit when working.

[0028] Specifically, the infrared touch frame of the present application includes a plurality of infrared receiving signal amplification circuits and a plurality of discharge control circuits. Each infrared receiving signal amplification circuit includes an amplification coupling capacitor. Each amplification coupling capacitor is grounded through each discharge control circuit. The on-time of each discharge control circuit can be used to control the grounding time of the corresponding amplification coupling capacitor, thereby independently controlling the discharge time of each amplification coupling capacitor.

[0029] Optionally, the infrared touch frame of the present application can further include a plurality of infrared emission circuits. The infrared emission circuit is used to emit infrared light to the corresponding infrared receiving signal amplification circuit. The infrared receiving signal amplification circuit converts the detection result of the infrared light into an electrical signal and amplifies it, which can prevent the signal of the detection result from being too weak to cause inaccurate sensing of the infrared touch frame. Among them, the infrared light emitted by the infrared emission circuit covers the infrared touch frame. The touch position of the user can be obtained according to the detection result of the infrared light by the infrared receiving signal amplification circuit.

[0030] Optionally, the infrared touch frame of the present application can further comprise a control circuit connected with the infrared emission circuit, the control circuit can control the circuit state of the infrared emission circuit, so that when the user needs to start the infrared touch function, the control circuit drives the infrared emission circuit to start to emit infrared light, and when the user does not need to start the infrared touch function, the control circuit drives the infrared emission circuit to stop emitting infrared light, thereby saving the power consumption of the infrared emission circuit.

[0031] Please refer to Figure 1 which is a flow chart of the amplification coupling capacitor discharging method of the first embodiment of the present application, the amplification coupling capacitor discharging method is applied to an infrared touch frame, the infrared touch frame comprises a plurality of infrared receiving signal amplification circuits, and the amplification coupling capacitor discharging method comprises:

[0032] S1: obtaining the infrared receiving gain position value of each infrared receiving signal amplification circuit.

[0033] The infrared receiving signal amplification circuit comprises an infrared receiving group and an amplification circuit, and the infrared receiving gain position value refers to the amplification position of the amplification circuit, which also indicates the amplification multiple of the amplification circuit.

[0034] S2: obtaining the target discharging time of the amplification coupling capacitor of the infrared receiving signal amplification circuit corresponding to the infrared receiving gain position value according to the preset gain position-discharging time corresponding relationship.

[0035] Since the larger the infrared receiving gain position value is, the smaller the amount of electrical signal accumulated by the corresponding amplification coupling capacitor is, therefore, according to the infrared receiving gain position value of each infrared receiving signal amplification circuit, the length of the discharging time of the amplification coupling capacitor can be obtained.

[0036] S3: driving each of the discharging control circuits to conduct according to the target discharging time, so that the corresponding amplification coupling capacitor is grounded, thereby discharging the amplification coupling capacitor of each infrared receiving signal amplification circuit.

[0037] Specifically, when the amplification coupling capacitor of the infrared receiving signal amplification circuit is discharging, the target discharging time can be counted down, and when the countdown is 0, the discharging is ended. Alternatively, when the amplification coupling capacitor of the infrared receiving signal amplification circuit is discharging, the target discharging time can be recorded, and when the target discharging time is equal to the corresponding discharging time, the discharging is ended.

[0038] Compared with the related art, the application can obtain a target discharge time of the amplification coupling capacitor according to the infrared receiving gain gear value of each infrared receiving signal amplification circuit, discharge the amplification coupling capacitor of each infrared receiving signal amplification circuit according to the target discharge time, and make the amplification coupling capacitor of each infrared receiving signal amplification circuit fully discharged, so as to avoid the influence of insufficient discharge on the output signal of the infrared receiving signal amplification circuit, and improve the accuracy of the output signal of the infrared receiving signal amplification circuit.

[0039] In a feasible embodiment, the gain gear-discharge time correspondence includes a plurality of candidate gears and corresponding candidate discharge times; S2: obtaining the target discharge time of the amplification coupling capacitor of the infrared receiving signal amplification circuit corresponding to the infrared receiving gain gear value according to the preset gain gear-discharge time correspondence, including:

[0040] S21: determining the candidate gear corresponding to the infrared receiving gain gear value from the plurality of candidate gears of the gain gear-discharge time correspondence, to obtain a target gear.

[0041] The gain gear-discharge time correspondence can be a relationship table or a functional relationship.

[0042] S22: determining the candidate discharge time corresponding to the target gear as the target discharge time.

[0043] The numerical unit of the target discharge time can be us. Specifically, one target gear corresponds to one target discharge time, and the target discharge time corresponding to the target gear can be obtained after the target gear is determined.

[0044] In this embodiment, the corresponding target gear can be determined according to the infrared receiving gain gear value, and the corresponding target discharge time can be determined according to the target gear, which is beneficial to accurately obtaining the target discharge time.

[0045] In a feasible embodiment, the preset gain gear-discharge time correspondence is a preset gain gear-discharge time correspondence table.

[0046] For example, the gain gear-discharge time correspondence table includes a first cell for storing candidate gears and a second cell for storing candidate discharge times. The correspondence between the first cell and the second cell can be that the first cell and the second cell in the same row correspond, or the first cell and the second cell in the same column correspond.

[0047] In the embodiment, the target gain position and the target discharge time corresponding to the infrared receiving gain position value can be quickly obtained through the table format of the gain position-discharge time corresponding relationship table, so that the effect of efficiently obtaining the target discharge time is realized.

[0048] In an available embodiment, the preset gain position-discharge time corresponding relationship is a relationship function. The relationship function can be a one-variable linear relationship function, a one-variable quadratic relationship function or a segmented function, etc.

[0049] The one-variable linear relationship function can be t=k*x+t0, where t is the output of the relationship function, k is a linear coefficient, x is the input gain position, and t0 is a basic time.

[0050] The one-variable quadratic relationship function can be t=k(x-s)^2+t0, where t is the output of the relationship function, k is a quadratic coefficient, x is the input gain position, s is a preset basic position, and t0 is a basic time.

[0051] The segmented function can be: where t is the output of the relationship function, x is the input gain position, and l is a preset position segmentation point.

[0052] According to the preset gain position-discharge time corresponding relationship, the target discharge time of the amplification coupling capacitor of the infrared receiving signal amplification circuit corresponding to the infrared receiving gain position value is obtained, and the step comprises:

[0053] The infrared receiving gain position value is taken as the input of the relationship function, and the output of the relationship function is determined as the target discharge time.

[0054] When the target discharge time has a minimum unit smaller than the preset discharge time, the integer value extraction can be used for processing. The integer value extraction refers to keeping only the value before the decimal point of the target discharge time and removing the value after the decimal point of the target discharge time, so that the target discharge time is an integer value. When the value after the decimal point of the target discharge time is removed, the value after the decimal point of the target discharge time is not rounded, so even if the value after the decimal point of the target discharge time is 7, 8 or 9, it will be directly removed.

[0055] In the embodiment, the target discharge time corresponding to the infrared receiving gain position value can be accurately obtained through the function relationship.

[0056] In a feasible embodiment, the infrared touch frame also includes a switch control module; each infrared receiving signal amplification circuit includes a switch component, and each switch component includes a driving end, a first end, and a second end; the driving end of each switch component is connected to the output end of the switch control module, the first end of each switch component is connected to one end of the corresponding capacitor, and the second end of each switch component is grounded.

[0057] The switch control module can output a switch control signal to the driving end of the switch component to switch the first end of the switch component and the second end of the switch component into a conductive relationship. For example, by outputting a switch-on signal, the first end of the switch component and the second end of the switch component are conductively connected; by outputting a switch-off signal, the first end of the switch component and the second end of the switch component are disconnected. Specifically, the switch component can be a switching component such as a triode or a field-effect transistor, or a switching circuit composed of multiple components.

[0058] S3: Discharging the amplifying coupling capacitors of each infrared receiving signal amplifying circuit according to the target discharge time includes:

[0059] According to the initialization sequence and discharge time of each infrared receiving signal amplifying circuit, the output end of the driving switch control module outputs a switch conduction signal to each switch component to turn on the switch component, so that each amplifying coupling capacitor discharges to the ground through the switch component at the corresponding target discharge time.

[0060] The initialization sequence refers to the sequence numbers of the infrared receiving signal amplifying circuits, and is also the discharge sequence of the corresponding amplifying coupling capacitors.

[0061] In this embodiment, the output end of the switch control module can be driven to output a switch-on signal to each switch component according to the initialization sequence and discharge time, thereby accurately controlling the discharge sequence and discharge time of each amplified coupling capacitor.

[0062] In a feasible embodiment, the infrared touch frame further includes a discharge control circuit.

[0063] The discharge control circuit, referred to as the MCU, is a chip that reduces the frequency and specifications of the central processing unit (CPU) and integrates memory, a timer, USB, A / D converter, UART, PLC, DMA, and other peripheral interfaces, as well as an LCD driver circuit. The discharge control circuit can be connected to the infrared receiver signal amplifier circuit via an I / O port to output a control signal to the infrared receiver signal amplifier circuit. The discharge control circuit is equipped with a timer that can output pulse waves to the infrared receiver signal amplifier circuit based on timing data simulated by the timer.

[0064] S3: according to the target discharge time, driving each of the discharge control circuits to turn on, so that the corresponding amplification coupling capacitor is grounded, thereby discharging the amplification coupling capacitor of each infrared receiving signal amplification circuit, comprising:

[0065] The target discharge time is transmitted to the discharge control circuit to control the discharge control circuit to output a timing level corresponding to the target discharge time to the corresponding infrared receiving signal amplification circuit, thereby controlling the discharge of the corresponding amplification coupling capacitor.

[0066] The amplification coupling capacitor charging and discharging time is affected by the control signal output by the discharge control circuit to the infrared receiving signal amplification circuit. The control signal output by the discharge control circuit is a timing level. When the timing level is a first level, the infrared receiving signal amplification circuit is turned on and the amplification coupling capacitor is discharged. When the timing level is a second level, the infrared receiving signal amplification circuit is turned off and the amplification coupling capacitor stops discharging. The first level and the second level are two opposite level signals, for example, using high level as the first level and low level as the second level, or using low level as the first level and high level as the second level. Alternatively, the discharge control circuit can be a circuit module or a micro control unit

[0067] In this embodiment, the discharge control circuit can be driven to control the discharge of each amplification coupling capacitor according to the target discharge time, so that the discharge time of each amplification coupling capacitor can be accurately controlled by the discharge control circuit, and the amplification coupling capacitor can be fully discharged.
