Description

Technical Field

[0001] This application relates to the technical field of capacitor discharge control, specifically to a method, apparatus, medium, device, and infrared touch frame for amplifying coupled capacitor discharge. Background Technology

[0002] The operation of the infrared touch frame requires the infrared receiving signal to be amplified by an infrared receiving signal amplification circuit before being input to the discharge control circuit. The infrared receiving signal amplification circuit includes an infrared receiving group and an amplification circuit. The signal output from the infrared receiving group is amplified by the amplification circuit and then input to the discharge control circuit. However, the infrared receiving signal amplification circuit typically includes amplification coupling capacitors to filter low-frequency interference. This can cause the accumulated electrical signal in the amplification coupling capacitors to affect the accuracy of the amplified signal. In related technologies, all infrared receiving signal amplification circuits use the same discharge time. However, the same discharge time cannot simultaneously meet the discharge requirements of the amplification coupling capacitors in infrared receiving signal amplification circuits with large differences in RAGC (Infrared Receiver Gain Levels). Therefore, some amplification coupling capacitors cannot be completely discharged, affecting the accuracy of the output signal when the infrared receiving signal amplification circuit is operating. Summary of the Invention

[0007] According to the target discharge time, each of the discharge control circuits is turned on, and the corresponding amplification coupling capacitor is grounded, thereby discharging the amplification coupling capacitor of each of the infrared receiving signal amplification circuits.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0022] It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of the embodiments of this application.

In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. The singular forms "a," "the," and "the" used in this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. The word "if" as used herein can be interpreted as "when," "when," or "in response to determination."

[0024] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0025] To better understand the technical solution of this application, the relevant application scenarios of this application are introduced below.

[0026] This application applies to an infrared touch frame, also known as an infrared touch control frame. The frame has multiple sets of infrared transmitting and receiving modules. Each set of infrared transmitting and receiving modules includes an infrared transmitting group and an infrared receiving group. The number of infrared transmitters in the infrared transmitting group is the same as the number of infrared receivers in the infrared receiving group. The infrared light emitted by the infrared transmitting group forms an infrared matrix on the surface of the infrared touch frame. The infrared receiving group can locate the position of the touch operation based on whether it receives the infrared light emitted by the corresponding infrared transmitting group, and then realize human-computer interaction based on the located position.

[0027] Since the electrical signal output by the infrared receiver group, reflecting the infrared light detection result, is a weak electrical signal, an amplifier circuit is needed to amplify it. Therefore, the infrared receiver group and the amplifier circuit form an infrared receiving signal amplifier circuit. The RAGC (Infrared Receiver Gain Level) of the infrared receiving signal amplifier circuit affects its amplification factor. However, since the capacitor parameters of infrared receiving signal amplifier circuits with different RAGCs may vary, and the actual amount of electrical signal accumulated by the capacitors of infrared receiving signal amplifier circuits with different RAGCs also varies, the same discharge time may cause some amplification coupling capacitors to fail to discharge completely, affecting the accuracy of the output signal when the infrared receiving signal amplifier circuit is working.

[0028] Specifically, the infrared touch frame of this application includes multiple infrared receiving signal amplification circuits and multiple discharge control circuits; each infrared receiving signal amplification circuit includes an amplification coupling capacitor; each amplification coupling capacitor is grounded through its respective discharge control circuit. The grounding time of the corresponding amplification coupling capacitor can be controlled by adjusting the conduction time of each discharge control circuit, thereby independently controlling the discharge time of each amplification coupling capacitor.

[0029] Optionally, the infrared touch frame of this application may further include multiple infrared emitting circuits. The infrared emitting circuits emit infrared light to corresponding infrared receiving signal amplification circuits. The infrared receiving signal amplification circuits convert the detection result of the infrared light into an electrical signal and amplify it, which can prevent the detection result signal from being too weak, leading to inaccurate sensing by the infrared touch frame. The infrared light emitted by the infrared emitting circuits covers the infrared touch frame, and the user's touch position can be obtained based on the detection result of the infrared light by the infrared receiving signal amplification circuits.

[0030] Optionally, the infrared touch frame of this application may also include a control circuit, which is connected to the infrared emitting circuit. The control circuit can control the circuit state of the infrared emitting circuit, so that when the user needs to activate the infrared touch function, the control circuit drives the infrared emitting circuit to start and emit infrared light, and when the user does not need to activate the infrared touch function, the control circuit drives the infrared emitting circuit to turn off and stop emitting infrared light, thereby saving the power consumption of the infrared emitting circuit.

[0031] Please see Figure 1 This is a flowchart of the amplification coupling capacitor discharge method according to the first embodiment of this application. The amplification coupling capacitor discharge method is applied to an infrared touch frame, which includes multiple infrared receiving signal amplification circuits. The amplification coupling capacitor discharge method includes:

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

[0033] The infrared receiving signal amplification circuit includes an infrared receiving group and an amplification circuit. The infrared receiving gain level value refers to the amplification level of the amplification circuit, which also indicates the amplification factor of the amplification circuit.

[0034] S2: Based on the preset gain level-discharge time correspondence, obtain the target discharge time of the amplification coupling capacitor of the infrared receiving signal amplification circuit corresponding to the infrared receiving gain level value.

[0035] Since a higher infrared receiver gain level results in a lower amount of electrical signal accumulated by the amplification coupling capacitor, the discharge time of the amplification coupling capacitor can be determined based on the infrared receiver gain level of each infrared receiver signal amplification circuit.

[0036] S3: Drive each of the discharge control circuits to conduct according to the target discharge 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, during the discharge of the amplification coupling capacitor in the infrared receiving signal amplification circuit, a countdown can be started based on the target discharge time. Discharge ends when the countdown reaches 0. Alternatively, the target discharge duration can be recorded during the discharge of the amplification coupling capacitor in the infrared receiving signal amplification circuit, and discharge ends when the target discharge duration equals the corresponding discharge time.

[0038] Compared to related technologies, this application can obtain the target discharge time of the corresponding amplification coupling capacitor based on the infrared receiving gain level of each infrared receiving signal amplification circuit. The amplification coupling capacitor of each infrared receiving signal amplification circuit is then discharged according to the target discharge time, so that the amplification coupling capacitor of each infrared receiving signal amplification circuit can be fully discharged. This avoids the output signal of the infrared receiving signal amplification circuit being affected by insufficient discharge, and can improve the accuracy of the output signal of the infrared receiving signal amplification circuit.

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

[0040] S21: From multiple candidate levels corresponding to the gain level-discharge time relationship, determine the candidate level corresponding to the infrared receiving gain level value to obtain the target level.

[0041] The relationship between gain level and discharge time can be a table or a function.

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

[0043] The unit for the target discharge time can be microseconds (µs). Specifically, each target gear level corresponds to a target discharge time. Once the target gear level is determined, the corresponding target discharge time can be obtained.

[0044] In this embodiment, the corresponding target level can be determined based on the infrared receiving gain level, and then the corresponding target discharge time can be determined based on the target level, which is beneficial for accurately obtaining the target discharge time.

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

[0046] For example, the gain level-discharge time correspondence table includes a first cell for storing candidate gain levels and a second cell for storing candidate discharge times. The correspondence between the first and second cells can be either within the same row or within the same column.

[0047] In this embodiment, the target gain level and target discharge time corresponding to the infrared receiving gain level can be quickly obtained through a table format of the gain level-discharge time correspondence table, thereby achieving the effect of efficiently obtaining the target discharge time.

[0048] In one feasible embodiment, the preset gain level-discharge time correspondence is a relational function. This relational function can be a linear function, a quadratic function, or a piecewise function, etc.

[0049] A linear function in one variable can be: t = k*x + t0; where t is the output of the function, k is the linear coefficient, x is the input gain level, and t0 is the base time.

[0050] A quadratic relational function can be: t = k(xs)^2 + t0; where t is the output of the relational function, k is the quadratic coefficient, x is the input gain level, s is the preset base level, and t0 is the base time.

[0051] A piecewise function can be: Where t is the output of the relational function, x is the input gain level, and l is the preset level division point.

[0052] The steps for obtaining the target discharge time of the amplification coupling capacitor of the infrared receiving signal amplification circuit corresponding to the infrared receiving gain level value, based on the preset gain level-discharge time correspondence, include:

[0053] The infrared receiver gain level is used as the input to the relational function, and the output of the relational function is used to determine the target discharge time.

[0054] When the target discharge time has a minimum unit smaller than the preset discharge time, it can be processed using integer value extraction. Integer value extraction means retaining only the value before the decimal point of the target discharge time and removing the value after the decimal point, so the target discharge time will always be an integer value. When removing the value after the decimal point of the target discharge time, no rounding is performed; therefore, even if the value after the decimal point of the target discharge time is 7, 8, 9, etc., it will be directly removed.

[0055] In this embodiment, the target discharge time corresponding to the infrared receiver gain level can be accurately obtained through a functional relationship.

[0056] In one feasible embodiment, the infrared touch frame further includes a switch control module; each infrared receiving signal amplification circuit includes a switch component, 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 switch the conduction relationship between the first and second terminals of the switch component by outputting a switch control signal to the drive terminal of the switch component. For example, by outputting a switch-on signal, the first and second terminals of the switch component are connected; by outputting a switch-off signal, the first and second terminals of the switch component are disconnected. Specifically, the switch component can use switching components such as transistors and field-effect transistors, or it can be a switch circuit composed of multiple components.

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

[0059] Based on the initialization sequence and discharge time of each infrared receiving signal amplification circuit, the output terminal of the drive switch control module outputs a switch-on signal to each switch component to turn on the switch component, so that each amplification coupling capacitor discharges to ground through the switch component at the corresponding target discharge time.

[0060] The initialization order refers to the sequence number of each infrared receiving signal amplification circuit, which is also the discharge order of the corresponding amplification coupling capacitor.

[0061] In this embodiment, the output terminal of the drive switch control module can output switch conduction signals to each switch component according to the initialization sequence and discharge time, so as to accurately control the discharge sequence and discharge time of each amplification coupling capacitor.

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

[0063] The discharge control circuit refers to the MCU, which is a chip that integrates a central processing unit (CPU) with a reduced frequency and specifications, along with peripheral interfaces such as memory, timer, USB, A / D converter, UART, PLC, DMA, and even the LCD driver circuit. The discharge control circuit can be connected to the infrared receiving signal amplification circuit via I / O ports to output control signals to it. The discharge control circuit also includes a timer, which can output pulse waves to the infrared receiving signal amplification circuit based on the timing data simulated by the timer.

[0064] S3: The step of driving each of the discharge control circuits to conduct according to the target discharge time, thereby grounding the corresponding amplification coupling capacitor and discharging the amplification coupling capacitor of each infrared receiving signal amplification circuit includes:

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

[0066] The charging and discharging time of the amplification coupling capacitor is affected by the control signal output from 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 the first level, the infrared receiving signal amplification circuit is turned on, and the amplification coupling capacitor discharges. When the timing level is the second level, the infrared receiving signal amplification circuit is turned off, and the amplification coupling capacitor stops discharging. The first and second levels are opposite signal levels; for example, a high level can be used as the first level and a low level as the second level. Optionally, a low level can be used as the first level and a high level as the second level. Optionally, the discharge control circuit can be a circuit module or a microcontroller 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 as to accurately control the discharge time of each amplification coupling capacitor and enable the amplification coupling capacitor to discharge fully.

[0071] The discharge module 103 is used to drive each of the discharge control circuits to conduct according to the target discharge time, so as to ground the corresponding amplification coupling capacitor, thereby discharging the amplification coupling capacitor of each infrared receiving signal amplification circuit.
