[0072] In the field of industrial control, the study of contact angle control is of great significance and importance, because it is directly related to the accuracy and predictability of the interaction between liquid and solid surface, which is essential to ensure the stability of the production process, improve product quality, reduce production costs, and meet strict environmental and safety standards.

[0073] Prior to the present invention, existing contact angle control methods mainly rely on precise mechanical adjustment and chemical treatment to adjust the contact angle between the liquid and the solid surface. This includes the use of high-precision displacement stages and pumps to accurately control the volume of the droplet and its relative position to the surface, or by changing the chemical composition and microstructure of the surface material to adjust its wettability.

Contact angle control technology needs to adapt to various types of liquid and solid materials, as well as different industrial environments and application scenarios, which places higher demands on the universality and adaptability of the technology.

[0074] In an embodiment of the present invention, a portable contact angle control circuit method and system are provided. The solution realizes accurate contact angle feedback analysis taking fluctuation into consideration by setting a high-precision universal online contact angle control and analysis system.

[0075] According to a first aspect of an embodiment of the present invention, a portable contact angle control circuit method is provided.

[0076] Figure 1 The present invention is a flowchart of a portable contact angle control circuit method according to an embodiment of the present invention.

[0077] In one or more embodiments, preferably, the portable contact angle control circuit method comprises:

[0078] S101. Set up portable power supply, auxiliary circuit, lighting and power structure and working mode;

[0079] S102, setting a contact angle measurement distance detection process and a sensor;

[0080] S103, calculating the contact angle and the control signal according to the feedback information of the detection circuit;

[0081] S104, estimating the future position of the device according to the current moving distance, and determining whether to start contact protection and overcurrent protection;

[0082] S105, providing information feedback according to a preset communication loop;

[0083] S106. Display online information and update settings in real time through a human-computer interaction interface.

[0084] In the embodiments of the present invention, in view of the difficulties and key points of the existing contact angle control methods, high-precision fine-tuning, surface treatment and analysis matching, real-time monitoring and feedback control, human-computer interaction and protection are combined to achieve efficient, fast and portable contact angle analysis and control.

[0085] Figure 2 The present invention is a flowchart of setting a portable power source, auxiliary circuit, lighting and power structure and working mode in a portable contact angle control circuit method according to an embodiment of the present invention.

[0086] like Figure 2 As shown, in one or more embodiments, preferably, the portable power supply, auxiliary circuit, lighting and power structure and working mode are provided, specifically including:

[0087] S201, setting a power supply circuit structure to provide a stable power supply;

[0088] S202, configuring a driving circuit based on a power supply, wherein a driving current is used to form a current output to supply power to a control circuit;

[0089] S203, automatically adjusting the power of the lighting circuit in real time according to different scenes;

[0090] S204, monitoring the energy consumption of the device in real time through battery power management, detecting in real time whether there is no one, and if there is no one, reducing the power consumption of the device to a preset level.

[0091] In an embodiment of the present invention, a power management system for a portable device is provided, including a power module circuit, an auxiliary circuit, a lighting control circuit, and a power monitoring and working mode adjustment mechanism. The system is designed to ensure stable power supply for portable devices and intelligently adjust power consumption according to the device usage scenario and power status to extend the working time of the device.

[0092] The power module circuit is configured to provide a stable DC power supply. The power module may include one or more battery cells, such as lithium-ion batteries or nickel-metal hydride batteries, as well as necessary protection circuits and voltage conversion circuits to ensure that the output voltage meets the operating voltage requirements of the device. In addition, the power module also integrates a power management chip that is responsible for monitoring the charge and discharge status of the battery, preventing overcharging and over-discharging, and providing battery health information.

[0093] Based on the power supply provided by the power module, the drive circuit is configured to form a current output for powering the control circuit. The drive circuit may include one or more switch mode power supplies (SMPS) that can efficiently convert the DC voltage of the power module to a voltage level suitable for the control circuit and other electronic components. The drive circuit also includes a current detection and regulation mechanism to ensure the stability and reliability of the supply current.

[0094] The lighting control circuit automatically adjusts the power according to different scenarios. The circuit includes an ambient light sensor for detecting the light intensity of the surrounding environment, and a microcontroller for adjusting the power of the lighting circuit according to the input data of the ambient light sensor. For example, in a low-light environment, the microcontroller can increase the power of the lighting circuit to improve the visibility of the device and the user's experience; while in an environment with sufficient light, the power is reduced to save energy.

[0095] The power monitoring and working mode adjustment mechanism monitors the energy consumption of the device in real time by managing the battery power. The mechanism includes a power monitoring module that detects the remaining battery power in real time and transmits this information to the microcontroller. The microcontroller dynamically adjusts the working mode of the device based on the power information and user-set parameters, such as the determination of unattended use. For example, when the device does not detect human operation within a certain period of time, the microcontroller can instruct the device to enter a low-power standby mode, reduce the screen brightness, turn off non-essential functions, or put the device into a sleep state, thereby reducing power consumption to a preset level.

[0096] In short, this solution can provide stable power supply and intelligently adjust power consumption according to the usage environment and power status to optimize the device usage time and user experience.

[0097] Figure 3 The present invention is a flowchart of a contact angle measurement distance detection process and a sensor in a portable contact angle control circuit method according to an embodiment of the present invention.

[0098] like Figure 3 As shown, in one or more embodiments, preferably, the contact angle measurement distance detection process and sensor are set, specifically including:

[0099] S301, presetting a sensor on the contact angle device to measure the distance to each surrounding area;

[0100] S302: Use the distance in each direction as the measured distance.

[0101] In an embodiment of the present invention, a contact angle measuring device is provided, which includes a preset sensor system for accurately measuring the contact angle formed by a liquid drop falling on a solid surface. The sensor system is configured to measure the distance from the liquid drop point to each surrounding area, and these distances are then used to calculate the size of the contact angle.

[0102] The sensor system includes multiple distance measuring sensors, such as laser rangefinders or infrared sensors, which are arranged at equal intervals on the circumference of the contact angle measuring device. Each sensor is able to independently measure the distance from the center point of the device to the edge of the solid surface. These sensors are connected to a microprocessor, which is responsible for collecting the data from each sensor and processing it.

[0103] During operation, a drop of liquid is first dropped on a solid surface, and then the sensor system is activated. Each sensor simultaneously measures the straight-line distance from its position to the point where the droplet contacts the surface. These distance data are transmitted to a microprocessor, which uses them to reconstruct the shape of the droplet on the solid surface and calculate the contact angle. Specifically, the microprocessor can calculate the height and bottom radius of the droplet through geometric algorithms, such as the Pythagorean theorem or triangulation, combined with distance data in different directions, and then derive the contact angle.

[0104] For example, if the sensor system includes four sensors, located in the north, south, east, and west directions, the distances measured by each sensor are N, S, E, and W. The microprocessor can use these distances to calculate the three-dimensional shape of the droplet and thus obtain the contact angle θ. The calculation formula can be a mathematical expression that combines trigonometric functions and geometric relationships to ensure the accuracy of the calculation results.

[0105] Figure 4 The present invention is a flowchart of a portable contact angle control circuit method for calculating a contact angle and a control signal according to feedback information from a detection circuit in one embodiment of the present invention.

[0106] like Figure 4 As shown, in one or more embodiments, preferably, the contact angle and control signal calculation according to the feedback information of the detection circuit specifically includes:

[0107] S401, analyzing and setting corresponding surface identification codes according to different industrial application scenarios;

[0108] S402, when the same surface identification code is obtained, calculating the corresponding measurement distance;

[0109] S403, calculating the contact angle using a first calculation formula according to the measured distance;

[0110] S404, determining whether the measured distance fluctuation in the past period of time satisfies the second calculation formula, and if so, updating the contact angle using the third calculation formula;

[0111] S405, using a proportional-integral-differential control algorithm to output a control signal according to a preset strategy based on the contact angle;

[0112] The first calculation formula is:

[0113] J=ARCSIN(D÷C)

[0114] Wherein, J is the contact angle, C is the measured distance in the moving direction, D is the nearest measured distance, and ARCSIN() is the inverse trigonometric function;

[0115] The second calculation formula is:

[0116] B<Y

[0117] Among them, B is the maximum value of the measured distance fluctuation in the same direction, and Y is the judgment margin;

[0118] The third calculation formula is:

[0119] J=ARCSIN((Davg+0.5×B)÷Cavg)

[0120] Wherein, J is the contact angle, Cavg is the average value of the measured distance in the moving direction, Davg is the average value of the nearest measured distance, and Arcsin() is the inverse trigonometric function.

[0121] In an embodiment of the present invention, a surface identification code is set: for each industrial application scenario, such as paint coating, glue bonding, etc., the system assigns a unique surface identification code. This identification code represents the characteristics of the solid surface in this scenario, such as material, roughness, etc. Calculate the measurement distance: when the system obtains a certain surface identification code, it uses sensors integrated on the device (such as a laser rangefinder) to measure the distance from the liquid drop point to each area around. These distance data are used to accurately calculate the contact angle. Preliminary calculation of the contact angle: The system calculates the contact angle according to the measured distance using the first calculation formula J = arcsin(DC), where J is the contact angle, C is the measurement distance in the moving direction, DD is the nearest measurement distance, and arcsin() is the inverse trigonometric function. Dynamic update of the contact angle: The system continuously monitors the measurement distance fluctuations in the past period of time and determines whether these fluctuations meet the second calculation formula B < Y, where B is the maximum value of the measurement distance fluctuation distance in the same direction, and Y is the preset judgment margin. If the condition is met, the contact angle is updated using the third calculation formula J = arcsin(Davg + 0.5×BCavg), where Cavg is the average value of the measurement distances in the moving direction, and Davg is the average value of the nearest measurement distances. Output control signal: According to the real-time updated contact angle, the system uses a proportional-integral-derivative (PID) control algorithm to output control signals according to a preset strategy. These signals can be used to adjust the flow rate, pressure or position of the liquid dispenser to optimize the spreading or penetration of the liquid on the solid surface. For example, during the coating process, if it is detected that the contact angle increases, indicating that the paint may not be fully spread, the system will correspondingly increase the output flow rate of the dispenser or adjust the coating speed to ensure the uniformity of the coating.

[0122] Figure 5 It is a flowchart of estimating the future position of the device according to the current moving distance and judging whether to start contact protection and overcurrent protection in a portable contact angle control circuit method according to an embodiment of the present invention.

[0123] As Figure 5 shown, in one or more embodiments, preferably, the estimating the future position of the device according to the current moving distance and judging whether to start contact protection and overcurrent protection specifically includes:

[0124] S501. Estimate whether there is a collision risk within the next 1 s according to the current moving speed. If there is, prompt for protection;

[0125] S502. Set up a protection circuit to judge overcurrent, overvoltage, and undervoltage. If the above situations exist, cut off the corresponding circuit to prevent equipment damage warning and misoperation.

[0126] In an embodiment of the present invention, a device protection system is provided, which estimates the future position by monitoring the moving distance and speed of the device in real time, thereby determining whether the contact protection and overcurrent protection functions need to be activated. The system includes a microprocessor connected to a motion sensor (such as an accelerometer or an encoder) to obtain the current moving speed of the device, and estimates whether the device has a collision risk in the next 1 second through an algorithm.

[0127] If the algorithm predicts a risk of collision, the system will immediately send a warning signal to the operator and prepare to activate contact protection mechanisms. Contact protection mechanisms can include mechanical barriers or emergency braking systems designed to reduce or avoid potential damage before an actual collision occurs.

[0128] In addition to collision risk assessment, the system also integrates protection circuits to monitor current and voltage conditions in the circuit. The protection circuit continuously detects overcurrent, overvoltage, and undervoltage conditions. These parameters outside the normal range may indicate circuit abnormalities, which, if not controlled, may cause equipment damage or safety accidents. The protection circuit is configured with a fast response mechanism, which can quickly cut off the affected circuit once any of the above conditions are detected to prevent equipment damage and misoperation.

[0129] For example, suppose the device is a mobile robot that moves on a set path. The robot's motion sensors constantly monitor its travel speed and direction. If the robot is about to collide with an obstacle, the system calculates the possibility of a collision and activates the mechanical brakes if necessary, while triggering sound or light signals to alert nearby personnel. At the same time, if the robot's battery pack output is abnormal, resulting in a sudden increase in current, the protection circuit will immediately cut off the power supply to prevent the battery from overheating or even catching fire, ensuring the safety of the robot and the operator.

[0130] Figure 6 The present invention is a flowchart of a portable contact angle control circuit method for performing information feedback according to a preset communication loop in one embodiment of the present invention.

[0131] like Figure 6 As shown, in one or more embodiments, preferably, the information feedback according to the preset communication loop specifically includes:

[0132] S601, obtaining the protection action status at the current moment, and providing feedback according to a preset communication loop;

[0133] S602: Obtain the current contact angle and control signal, and feed back to the human-computer interaction module through the communication loop.

[0134] In an embodiment of the present invention, an information feedback system is provided, which obtains and feeds back information on protection action conditions, contact angles, and control signals in real time through a pre-set communication loop. The system includes a central processing unit (CPU), multiple sensors, a communication module, and a human-computer interaction interface.

[0135] First, the system monitors the protection action status of the equipment in real time through an integrated sensor network. These sensors can be temperature sensors, pressure sensors, current sensors, etc., which can detect abnormal conditions in the operation of the equipment, such as overheating, overload, short circuit, etc. Once these protection action conditions are detected, the sensors immediately send the data to the CPU.

[0136] After receiving the protection action data, the CPU uses a preset communication loop to encode the information and send it out through the communication module. The communication loop can be wired or wireless, including but not limited to Ethernet, Wi-Fi, Bluetooth or cellular network. In this way, the remote monitoring center or relevant management personnel can receive the protection action information in real time and take corresponding measures based on the information.

[0137] In addition to the protection action information, the system also obtains contact angle and control signal data in real time. The contact angle data is provided by the contact angle measurement module, which calculates the contact angle by analyzing the shape of the liquid on the solid surface. The control signal data comes from the control unit, which generates a control signal based on the contact angle and other parameters to adjust the operation of the device.

[0138] These contact angle and control signal data are also processed by the CPU and transmitted to the human-machine interaction module via the communication circuit. The human-machine interaction module can be a display screen, touch screen or mobile application, which displays these data in an intuitive way so that operators can directly understand the current equipment status and control situation.

[0139] For example, suppose the equipment is an industrial coating machine, and the coating quality is affected by the contact angle between the coating and the substrate. The system monitors the contact angle in real time and transmits the data to the operator's console through a communication loop. If the contact angle exceeds the preset range, the system automatically adjusts the coating parameters and feeds back the adjusted control signal and the new contact angle data to the human-computer interaction module. The operator can immediately see the adjustment results to ensure the stability of the coating process and product quality.

[0140] Figure 7 The present invention is a flowchart of a portable contact angle control circuit method for real-time online information display and setting update through a human-computer interaction interface in an embodiment of the present invention.

[0141] like Figure 7As shown, in one or more embodiments, preferably, the real-time online information display and setting update through the human-computer interaction interface specifically includes:

[0142] S701, displaying online information according to the contact angle at the current moment;

[0143] S702. Setting and switching different operation scenarios online.

[0144] In an embodiment of the present invention, a human-computer interaction system is provided, which can display online information of contact angle in real time and allow users to set and switch according to different operation scenarios. The system includes a human-computer interaction interface (HMI), a central processing unit (CPU) and necessary input / output devices.

[0145] The human-machine interface is the communication bridge between the system and the operator. It can be a touch screen, a computer interface or a customized control panel. The interface design is friendly to ensure that the operator can easily view and input information.

[0146] In terms of real-time online information display, the system continuously monitors the contact angle between the liquid and the solid surface through the contact angle measurement module. These measurement results are transmitted to the CPU in real time, and after processing, the contact angle data is dynamically displayed on the human-computer interaction interface. For example, if the contact angle is 75 degrees, this number will be updated in real time and displayed on the interface. This instant feedback allows operators to have an intuitive understanding of the current process and make corresponding adjustments based on the displayed contact angle data.

[0147] In addition, the human-computer interaction interface also provides scene setting and switching functions. Operators can preset multiple operating scenarios according to different application requirements. Each scenario defines a specific set of parameters, such as liquid dispensing rate, dispensing volume, and desired contact angle range. Operators can easily switch between these preset scenes through buttons or menus on the interface without having to manually adjust each parameter, thereby improving work efficiency and reducing human errors.

[0148] For example, suppose a production process requires two different coating thicknesses. The operator can preset two scenarios on the human-machine interface: one for thinner coating with a contact angle of 60 degrees; the other for thicker coating with a contact angle of 80 degrees. During the production process, according to product requirements, the operator only needs to simply select the corresponding scenario on the interface, and the system will automatically adjust the parameters to achieve fast switching.
