Description
Technical Field
[0001] This invention relates to the field of intelligent counting technology, specifically to an intelligent counting method and system for diamond drawing and dotting. Background Technology
[0002] Diamond painting, also known as dotting, is a handcrafted process that uses a special brush to pick up resin or acrylic "diamond" particles with a diameter of 2-5mm one by one and then precisely press them onto corresponding adhesive dots on the canvas. The process involves a three-step cycle of "picking up the diamond, positioning, and gently pressing" to fix each individual diamond, ultimately piecing them together to form a decorative painting with a sparkling visual effect. It is one of the fastest-growing categories in the DIY leisure field in recent years.
[0003] As the number of diamonds in a single piece has skyrocketed from hundreds to tens of thousands, the traditional counting method of "human mental counting + pen and paper marking" has become a bottleneck. Users' attention is easily distracted, leading to omissions and re-counting, with an error rate generally exceeding 15%. If something is forgotten midway, large-scale rework and verification are necessary. Furthermore, progress perception relies entirely on visual estimation of the completed canvas area, which easily leads to a sense of frustration when working on high-density color areas, resulting in a feeling of "getting slower and slower." Industry research shows that about 40% of users reduce their creation frequency as a result, and 30% of large-scale works are abandoned midway. Although electronic diamond counting pens have appeared on the market to try to solve the counting problem, the fixed threshold cannot be adjusted according to individual habits due to the large differences in the pressure applied by different users, making it easy to trigger erroneously and resulting in poor counting accuracy. Therefore, based on the above problems, an intelligent counting method and system for diamond painting is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide an intelligent counting method and system for diamond dotting, in order to solve the problems of large errors caused by relying on manual counting in existing diamond dotting methods and the high error trigger rate of existing electronic diamond counting pens, resulting in poor counting accuracy.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A smart counting system for diamond drawing and dotting includes a mechanical sensing module, a signal processing counting module, a power management module, a power supply, function buttons, and a display output module. The mechanical sensing module is a sensing and transmission component installed inside the pen body, used to convert the pressing action during dotting into an electrical signal and output it to the signal processing counting module. It includes a dotting unit, a transmission unit, a pressure triggering unit, and a reset unit. The point-picking unit, which is a silicone rubber head, is responsible for picking up resin or acrylic diamond particles with a diameter of 2-5mm and pressing the diamonds onto the canvas adhesive dots under pressure, while transmitting mechanical displacement to the conduction unit. The transmission unit is responsible for transmitting the micro-displacement and micro-pressure generated by the silicone rubber head to the pressure triggering unit without loss. The pressure triggering unit is a miniature thin-film pressure sensor, which is responsible for converting the mechanical pressure transmitted by the transmission unit into an analog electrical signal, which is then sent to the signal processing and counting module via a signal transmission line. The reset unit is responsible for elastically resetting the transmission unit after a single drilling operation, so that the mechanical sensing module returns to the ready-to-trigger state. The signal processing and counting module is responsible for amplifying, converting, and thresholding the analog electrical signal, accumulating and counting the number of effective drilling operations, calculating the progress percentage, and sending the results to the display output module. It includes a signal amplification circuit, an AD converter, a threshold judgment unit, and a data processing, counting, and storage unit. The signal amplification circuit is responsible for amplifying the weak analog electrical signal output by the pressure triggering unit, improving the signal-to-noise ratio, and sending the amplified signal to the AD converter. The AD converter is responsible for converting the amplified analog electrical signal into a digital signal and outputting it to the threshold judgment unit. The threshold judgment unit is responsible for comparing the digital signal with the preset pressure threshold and outputting a valid trigger pulse only when the threshold is reached or exceeded, so as to eliminate false triggers and interference. The data processing counting and storage unit is responsible for receiving valid trigger pulses to complete the cumulative counting, calculating the progress ratio of the current count to the preset total, and writing the data into the built-in EEPROM to achieve power-off preservation. At the same time, the cumulative value and progress percentage information are sent to the display output module. The power management module is responsible for real-time monitoring of the voltage output by the power supply. The power supply, consisting of a battery compartment and button batteries, is responsible for powering the entire system's functions and can ensure continuous and stable operation of the entire system by replacing the button batteries when the power is depleted. Function keys are responsible for receiving mechanical operation commands from users, including reset key, up key, down key, confirm key and return key; The display output module is responsible for displaying count data, threshold settings, and warning information, including the count interface, threshold setting interface, and warning interface.
[0006] Preferably, the counting interface is responsible for displaying the cumulative count value and progress percentage data sent by the signal processing counting module, and can switch cyclically between the two display states of "cumulative value / progress percentage".
[0007] Preferably, the threshold setting interface is used to display and allow the user to adjust the current pressure trigger threshold. The up key is used to increase the current pressure trigger threshold, the down key is used to decrease the current pressure trigger threshold, and the confirmation key is used to confirm and save the selected threshold, which is written into the EEPROM of the data processing counter and storage unit to realize the custom calibration and power-off memory of the pressure trigger threshold.
[0008] Preferably, pressing the up button, down button, and confirmation button automatically enters the threshold setting interface. Pressing the up button increases the pressure trigger threshold by one, pressing the down button decreases the pressure trigger threshold by one, and the return button is used to return from the threshold setting interface to the counting interface.
[0009] Preferably, when the reset button is pressed briefly for less than 1 second, a signal is sent to the display output module to clear and turn off the current value display. When the reset button is pressed for a long time for 1 second, a switching signal is sent to the counting interface of the display output module to cycle between the two display states of "cumulative value / progress percentage". When the reset button is pressed for a long time for 3 seconds, a full reset signal is sent to restore the cumulative count, preset total and display output to the factory default values.
[0010] Preferably, when the power supply voltage is lower than 2.7V, the power management module sends a low voltage signal to the display output module, causing the display output module to enter an alarm interface. The alarm interface displays a "Low Bat" prompt signal and controls the backlight to decrease.
[0011] Preferably, a counting method includes the following steps: S1 presets a pressure threshold. When the user presses any one of the up, down, or confirmation keys, the display output module immediately switches to the threshold setting interface and displays the current pressure trigger threshold in real time. Subsequently, the user increases the threshold step by step by short-pressing the up key, or decreases the threshold step by step by short-pressing the down key, until the value matches the user's preferred pressure level. After confirming that everything is correct, the user short-presses the confirmation key, and the system writes the selected pressure trigger threshold into the EEPROM of the data processing counter and storage unit for storage, while the interface displays a "Saved" prompt. Finally, the user short-presses the return key, and the display screen returns from the threshold setting interface to the counting interface. At this point, the threshold setting is complete, and the system enters the drilling standby state. In the S2 picking stage, the picking point unit of the mechanical sensing module gently touches the surface of the diamond. The picking point unit, i.e. the silicone tip, picks up the diamond by relying on the surface adhesion of the food-grade silicone itself. During the S3 dotting trigger phase, the user maintains the dotting position, aligns the dotting unit with the corresponding adhesive dot on the canvas, and slowly applies downward pressure according to the user's own habits, causing the dotting unit to press onto the corresponding adhesive dot on the canvas. The dotting unit is displaced by the pressure, and this displacement is transmitted losslessly through the transmission unit to the pressure trigger unit, causing the miniature thin-film pressure sensor to deform under pressure. The sensor then converts the mechanical pressure into a weak analog electrical signal proportional to it, and sends it to the signal processing and counting module through the signal transmission line. The signal amplification circuit inside the signal processing and counting module first amplifies the weak analog electrical signal to improve the signal-to-noise ratio. The amplified analog signal is then sent to the AD converter, which quantizes it into a digital signal and outputs it to the threshold judgment unit. The threshold judgment unit compares the real-time digital signal with the EEPR... The system compares the signal with the preset pressure threshold stored in the OM (Operation Memory). Only when the signal amplitude reaches or exceeds the threshold is the action considered "valid drilling," and a valid trigger pulse is immediately output to the data processing, counting, and storage unit. Upon receiving the pulse, the data processing, counting, and storage unit increments the cumulative count by one, then reads the preset total, calculates the progress percentage of the current count relative to the total, and synchronously writes the updated cumulative value and percentage data to the built-in EEPROM to ensure data integrity after power failure. After the write operation is complete, the data processing, counting, and storage unit sends the new cumulative value and progress percentage information to the display output module in real time for user viewing. At this point, a complete "drilling-trigger-counting-display" closed-loop process ends, and the system re-enters the ready-to-trigger state. In the S4 display and feedback phase, after the display output module receives data, it displays the cumulative value or progress percentage information through the counting interface. The default display mode is "cumulative value", which directly displays the new total number of diamonds. If the user previously switched the counting interface to the "progress percentage" display mode by pressing and holding the reset button for 1 second, the progress percentage information will be displayed simultaneously. S5 Reset and Mode Switching: A short press of the reset button for less than 1 second will only clear the current display of the counting interface of the off display output module, without clearing the cumulative value; a long press for 1 second will cycle between the two display modes of "cumulative value / progress percentage"; a long press for 3 seconds will perform a "full reset", restoring the cumulative count and preset total to factory default values; The S6 low battery warning and power management module's low battery detection circuit monitors the power supply voltage in real time. When the voltage is <2.7V, it sends a low battery signal to the display output module, causing the display output module to enter the warning interface. The warning interface will display a "LowBat" prompt signal and control the backlight to decrease in order to extend the remaining battery life and remind the user to replace the power supply's button battery. After the S7 cycle resets and completes a single drilling cycle, the user releases the pressure, and the reset unit elastically resets the transmission unit after completing one drilling cycle, restoring the mechanical sensing module to the ready-to-trigger state, waiting for the next pick-up-drilling cycle; through the above steps, one intelligent and accurate drilling counting cycle is completed.
[0012] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a structure consisting of a mechanical sensing module, a signal processing and counting module, function buttons, and a display output module is used. The mechanical sensing module converts the pressing action during drilling into an electrical signal and outputs it to the signal processing and counting module. The signal processing and counting module is responsible for amplifying, converting, and thresholding the analog electrical signal, accumulating the effective number of drillings, calculating the progress percentage, and sending the results to the display output module for display. The function buttons receive the user's mechanical operation commands, allowing adjustment of the current pressure trigger threshold to match the user's preferred pressure level. They also allow switching the display mode of the counting interface on the display output module. This intelligent counting method and system for diamond drawing drilling achieves a closed-loop system of "adaptive threshold - micro-force sensing - real-time counting - progress visualization - power consumption management," improving the accuracy and stability of drilling counting. It solves the problems of large errors caused by manual counting in existing diamond drawing drilling methods and high error trigger rates in existing electronic diamond counting methods, resulting in poor counting accuracy.

Detailed Implementation
[0014] Please see Figure 1-5 The present invention provides a technical solution: A smart counting system for diamond drawing and dotting includes a mechanical sensing module, a signal processing counting module, a power management module, a power supply, function buttons, and a display output module. The mechanical sensing module is a sensing and transmission component installed inside the pen body, used to convert the pressing action during dotting into an electrical signal and output it to the signal processing counting module. It includes a dotting unit, a transmission unit, a pressure triggering unit, and a reset unit. The point-picking unit, with a silicone rubber head, is responsible for picking up resin or acrylic diamond particles with a diameter of 2-5mm and pressing the diamonds onto the canvas adhesive dots under pressure, while simultaneously transmitting mechanical displacement to the transmission unit. The transmission unit is responsible for transmitting the micro-displacement and micro-pressure generated by the silicone rubber head to the pressure triggering unit without loss. The pressure triggering unit is a miniature thin-film pressure sensor responsible for converting the mechanical pressure transmitted by the transmission unit into an analog electrical signal, which is then sent to the signal processing and counting module via a signal transmission line. The reset unit is responsible for elastically resetting the transmission unit after each drilling operation, so that the mechanical sensing module returns to the ready-to-trigger state. The signal processing and counting module is responsible for amplifying, converting, and thresholding analog electrical signals, accumulating and counting the number of effective drilling operations, calculating the progress percentage, and sending the results to the display output module. It includes a signal amplification circuit, an AD converter, a threshold judgment unit, and a data processing, counting, and storage unit. The signal amplification circuit is responsible for amplifying the weak analog electrical signal output by the pressure triggering unit, improving the signal-to-noise ratio, and sending the amplified signal to the AD converter. The AD converter is responsible for converting the amplified analog electrical signal into a digital signal and outputting it to the threshold judgment unit; The threshold judgment unit is responsible for comparing the digital signal with the preset pressure threshold and outputting a valid trigger pulse only when the threshold is reached or exceeded, so as to eliminate false triggers and interference. The data processing, counting, and storage unit is responsible for receiving valid trigger pulses to complete the cumulative counting, calculating the progress percentage of the current count and the preset total, and writing the data into the built-in EEPROM to save it when power is off. At the same time, it sends the cumulative value and progress percentage information to the display output module. The power management module is responsible for real-time monitoring of the power supply output voltage; The power supply, consisting of a battery compartment and button batteries, is responsible for powering the entire system's functions and can ensure continuous and stable operation of the entire system by replacing the button batteries when the power is depleted. Function keys are responsible for receiving mechanical operation commands from users, including reset key, up key, down key, confirm key and return key; The display output module is responsible for displaying count data, threshold settings, and warning information, including the count interface, threshold setting interface, and warning interface.
[0015] The counting interface displays the cumulative count value and progress percentage data sent by the signal processing counting module. It allows users to cycle between two display states: "Cumulative Value / Progress Percentage," facilitating observation of the drilling count. The threshold setting interface displays and allows users to adjust the current pressure trigger threshold. The up key increases the current pressure trigger threshold, the down key decreases it, and the confirmation key confirms and saves the selected threshold, writing it to the EEPROM of the data processing counting and storage unit. This enables custom calibration and power-off memory of the pressure trigger threshold. Pressing the up, down, or confirmation key automatically enters the threshold setting interface. Pressing the up key increments the pressure trigger threshold by one, and pressing the down key decrements it by one. The back key returns from the threshold setting interface to the counting interface. This allows users to adjust the current pressure trigger threshold to match their preferred pressure level, improving the accuracy of counting during drilling. A short press of the reset button (<1s) sends a signal to the display output module to clear and turn off the current value display. A long press of the reset button (1s) sends a switching signal to the display output module's counting interface, cycling between "cumulative value / progress percentage" display states. A long press of the reset button (3s) sends a full reset signal, restoring the cumulative count, preset total, and display output to factory default values. This setting allows users to switch the counting display mode and clear / reset the count. The power management module sends a low-voltage signal to the display output module when the power supply voltage is below 2.7V, causing the display output module to enter a warning interface displaying "Low". The system sends a "Bat" warning signal and controls the backlight to decrease. This setting visually reminds the user to replace the power button battery in a timely manner, preventing the loss of counting data due to sudden power outages. It also reduces the rate of remaining power consumption by about 40% by decreasing the backlight current, which can extend emergency use time by 3-5 days. At the same time, the system maintains normal counting function and writes data to the EEPROM, ensuring that every drilling data point during the low power period is still reliably recorded.
[0016] Workflow: The intelligent counting method for diamond drawing is as follows: A pressure threshold is preset. When the user presses any one of the up, down, or confirm keys, the display output module immediately switches to the threshold setting interface and displays the current pressure trigger threshold in real time. Subsequently, the user increases the threshold step-by-step by short-pressing the up key or decreases it step-by-step by short-pressing the down key until the value matches the user's preferred pressure level. After confirmation, the user short-presses the confirm key, and the system writes the selected pressure trigger threshold into the EEPROM of the data processing counting and storage unit for storage, while the interface displays a "Saved" message. Finally, the user short-presses the return key, and the display screen returns from the threshold setting interface to the counting interface. At this point, the threshold setting is complete, and the system enters the ready-to-drill state. Pick-up phase: The picking unit of the mechanical sensing module lightly touches the diamond surface, and the picking unit, i.e., the silicone tip, picks up the diamond using the surface adhesion of food-grade silicone. Pointing trigger phase: The user maintains the picking posture, aligns the picking unit with the corresponding adhesive point on the canvas, and slowly applies downward pressure according to the user's own habits, causing the diamond to press onto the corresponding adhesive point on the canvas. The picking unit is displaced by the pressure, and this displacement is transmitted losslessly through the transmission unit to the pressure trigger unit, causing the miniature thin-film pressure sensor to deform under pressure. The sensor then converts the mechanical pressure into a weak analog electrical signal proportional to it, and sends it to the signal processing and counting module through the signal transmission line. The signal amplification circuit inside the signal processing and counting module first processes the weak analog electrical signal... Gain amplification is performed to improve the signal-to-noise ratio. The amplified analog signal is sent to an AD converter, which quantizes it into a digital signal and outputs it to the threshold judgment unit. The threshold judgment unit compares the real-time digital signal with the preset pressure threshold stored in the EEPROM. Only when the signal amplitude reaches or exceeds the threshold is the action determined as "valid drilling," and a valid trigger pulse is immediately output to the data processing, counting, and storage unit. Upon receiving the pulse, the data processing, counting, and storage unit increments the cumulative count by one, then reads the preset total, calculates the progress percentage of the current count relative to the total, and synchronously writes the updated cumulative value and percentage data to the built-in EEPROM to ensure data is not lost after power failure. After the write operation, the data processing counting and storage unit sends the new cumulative value and progress percentage information to the display output module in real time for the user to view; at this point, a complete "drilling-triggering-counting-displaying" closed-loop process ends, and the system re-enters the ready-to-trigger state; Display and feedback stage: After receiving the data, the display output module displays the cumulative value or progress percentage information through the counting interface. The default is the "cumulative value" display mode, which directly displays the new total number of diamonds; if the user previously switched the counting interface to the "progress percentage" display mode by pressing and holding the reset button for 1 second, the progress percentage information will be displayed simultaneously; Reset and mode switching: Pressing the reset button for less than 1 second will only clear the current display of the counting interface of the display output module, without clearing the cumulative value;A 1-second press cycles through the "Cumulative Value / Progress Percentage" display modes; a 3-second press performs a "Full Reset," restoring the cumulative count and preset total to factory default values; Low Battery Warning: The power management module's low battery detection circuit monitors the power supply voltage in real time; when the voltage is <2.7V, a low-voltage signal is sent to the display output module, causing it to enter a warning interface, which displays "Low". The system sends a "Bat" signal and controls the backlight to decrease, extending the remaining battery life and reminding the user to replace the button battery. Cyclic reset: After completing a single drill biting cycle, the user releases the pressure, and the reset unit elastically resets the conduction unit, restoring the mechanical sensing module to a ready-to-trigger state, awaiting the next pick-up-drilling cycle. Through these steps, a smart and accurate drill biting counting cycle is completed, realizing a smart counting method and system for diamond painting. Through a closed-loop system of "adaptive threshold – micro-force sensing – real-time counting – progress visualization – power consumption management," the accuracy and stability of drill biting counting are improved. This solves the problems of large errors caused by manual counting in existing diamond painting drill biting systems and high error triggering rates in existing electronic diamond counting pens, resulting in poor counting accuracy.

7. A counting method for use in the intelligent counting system for diamond dotting as described in claims 1-6, characterized in that, Includes the following steps: The S1 presets a pressure threshold. When the user presses any one of the up, down, or confirmation keys, the display output module immediately switches to the threshold setting interface and displays the current pressure trigger threshold in real time. The user then increases the threshold step-by-step by short-pressing the up key or decreases it step-by-step by short-pressing the down key until the value matches the user's preferred pressure level. After confirmation, the user short-presses the confirmation key, and the system writes the selected pressure trigger threshold into the EEPROM of the data processing counter and storage unit, simultaneously displaying a "Saved" message. Finally, the user short-presses the return key, and the display screen returns from the threshold setting interface to the counting interface. The threshold setting is now complete, and the system enters the drilling standby state. In the S2 picking stage, the picking point unit of the mechanical sensing module gently touches the surface of the diamond. The picking point unit, i.e. the silicone tip, picks up the diamond by relying on the surface adhesion of the food-grade silicone itself. During the S3 dotting trigger phase, the user maintains the picking-up position, aligns the dotting unit with the corresponding adhesive dot on the canvas, and slowly applies downward pressure according to the user's own habits. This causes the dotting unit to press against the corresponding adhesive dot on the canvas, displacing it under pressure. This displacement is transmitted losslessly through the transmission unit to the pressure trigger unit, causing the miniature thin-film pressure sensor to deform under pressure. The sensor then converts the mechanical pressure into a weak analog electrical signal proportional to it, and sends it to the signal processing and counting module through the signal transmission line. The signal amplification circuit inside the signal processing and counting module first amplifies the weak analog electrical signal to improve the signal-to-noise ratio. The amplified analog signal is then sent to the AD converter, which quantizes it into a digital signal and outputs it to the threshold judgment unit. The threshold judgment unit compares the real-time digital signal with the preset pressure threshold stored in the EEPROM. Only when the signal amplitude reaches or exceeds the threshold is the current action determined as "valid drilling," and a valid trigger pulse is immediately output to the data processing, counting, and storage unit. After receiving the pulse, the data processing, counting, and storage unit performs an "increment" operation on the cumulative count, then reads the preset total, calculates the progress percentage of the current count and the total, and synchronously writes the updated cumulative value and percentage data to the built-in EEPROM to ensure that the data is not lost after power failure. After completing the write operation, the data processing, counting, and storage unit sends the new cumulative value and progress percentage information to the display output module in real time for the user to view. At this point, a complete closed-loop process of "drilling - triggering - counting - displaying" is completed, and the system re-enters the waiting-to-trigger state; In the S4 display and feedback phase, after the display output module receives data, it displays the cumulative value or progress percentage information through the counting interface. The default display mode is "cumulative value", which directly displays the new total number of diamonds. If the user previously switched the counting interface to the "progress percentage" display mode by pressing and holding the reset button for 1 second, the progress percentage information will be displayed simultaneously. S5 Reset and Mode Switching: A short press of the reset button for less than 1 second will only clear the current display of the counting interface of the off display output module, without clearing the cumulative value; a long press for 1 second will cycle between the two display modes of "cumulative value / progress percentage"; a long press for 3 seconds will perform a "full reset", restoring the cumulative count and preset total to factory default values; The S6 low battery warning and power management module's low battery detection circuit monitors the power supply voltage in real time. When the voltage is <2.7V, it sends a bottom line signal to the display output module, causing the display output module to enter the warning interface. The warning interface will display a "LowBat" prompt signal and control the backlight to decrease in order to extend the remaining battery life and remind the user to replace the power supply's button battery. After the S7 cycle resets and completes a single drilling cycle, the user releases the pressure, and the reset unit elastically resets the transmission unit after completing one drilling cycle, restoring the mechanical sensing module to the ready-to-trigger state, waiting for the next pick-up-drilling cycle; through the above steps, one intelligent and accurate drilling counting cycle is completed.
