Description
Glow discharge control methods, devices, and equipment Technical Field
[0001] This invention relates to the field of glow discharge technology, specifically to glow discharge control methods, devices, and equipment. Background Technology
[0002] Due to its advantages such as not requiring vacuum equipment, high chemical activity, and low gas temperature, atmospheric pressure low-temperature plasma has been increasingly widely used in industrial production in recent years, such as ozone preparation, material surface modification, thin film deposition, disinfection and sterilization, waste gas treatment, and the development of high-power lasers.
[0003] Glow discharge is a type of atmospheric pressure low-temperature plasma. It boasts advantages such as uniform discharge, no damage to material surfaces, and high efficiency. However, glow discharge also presents challenges. Discharge instability makes it prone to developing into filamentary discharge. These instabilities primarily include ionization instability and thermal instability. Ionization instability refers to the distortion of the electric field caused by changes in electron energy distribution during discharge. Increased local electric field strength (f) leads to increased local ionization rate, resulting in filamentary discharge. Thermal instability refers to the increased local gas temperature and decreased neutral particle number density at higher current densities, leading to enhanced discharge and further temperature increases. This creates a positive feedback mechanism, forming a strong ionization channel locally, causing the discharge to transform into filamentary discharge. Furthermore, overheating during glow discharge can cause irreversible damage, leading to electrode failure.
[0004] In related technologies, the problem of ionization instability can be effectively solved by selecting the structure and materials. However, thermal factors still have a significant impact on the intensity of glow discharge of the electrode. Therefore, it is of great significance to solve the problem of glow discharge instability or even electrode failure caused by thermal factors. Summary of the Invention
[0005] This invention provides a glow discharge control method, apparatus, and glow discharge equipment to solve the problem of unstable discharge caused by thermal factors during the glow discharge process in related technologies.
[0006] In a first aspect, the present invention provides a glow discharge control method applied to a glow discharge device, the glow discharge device comprising: a glow discharge component and a temperature regulating device, the glow discharge component being composed of a plurality of discharge electrodes, the method comprising: acquiring an initial ambient temperature of the environment in which the glow discharge component is located, and determining a target temperature and a target regulation range of a temperature regulating parameter based on the initial ambient temperature, the temperature regulating parameter being an operating parameter of the temperature regulating device used to regulate the ambient temperature of the environment in which the glow discharge component is located; controlling the glow discharge component to operate with a first operating parameter, and controlling the temperature regulating device to operate with a maximum temperature regulating parameter within the target regulation range, the maximum temperature regulating parameter being... The temperature regulation parameter is the one with the strongest ability to regulate ambient temperature within the target regulation range. After the temperature regulation device has been running for a first period of time, the glow discharge component is switched to operate with the second operating parameter, and the temperature regulation parameter of the temperature regulation device is reduced until the current ambient temperature of the environment where the glow discharge component is located reaches the target temperature or the temperature regulation parameter of the temperature regulation device reaches the minimum temperature regulation parameter of the target regulation range. Then, the glow discharge component is switched to operate with the third operating parameter. The temperature regulation parameter of the temperature regulation device is adjusted based on the relationship between the current ambient temperature and the target temperature so that the current ambient temperature is within the temperature range corresponding to the target temperature.
[0007] This invention first obtains the initial ambient temperature of the glow discharge module, determines the suitable target temperature and the target adjustment range of the temperature regulation parameters, ensuring the accuracy of temperature control and avoiding subsequent temperature runaway due to improper initial parameters. Controlling the glow discharge module with the first operating parameter and the temperature regulation device with the maximum parameter allows the module to quickly enter the working state and efficiently regulate the ambient temperature, shortening the start-up time. After the first period of operation, the module is switched to the second operating parameter, while the temperature regulation parameter is reduced to prevent the temperature from rising too quickly and exceeding the normal glow discharge temperature range. Once the temperature reaches the target or the parameter reaches its minimum value, the module is switched to the third operating parameter, and the parameter is adjusted according to the temperature relationship to stably maintain the ambient temperature within the target range. This phased dynamic adjustment method effectively solves the thermal stability problem of glow discharge, preventing weak discharge from affecting performance or overheating from causing glow discharge module failure, ensuring the stable and efficient operation of the entire glow discharge equipment.
[0008] In one optional implementation, determining the target temperature and the target adjustment range of the temperature adjustment parameters based on the initial ambient temperature includes: determining a target temperature range corresponding to the initial ambient temperature; determining a target temperature corresponding to the target temperature range based on the correspondence between preset temperature ranges and target temperatures, wherein different preset temperature ranges are negatively correlated with the target temperature; and determining a target adjustment range corresponding to the target temperature range based on the relationship between preset temperature ranges and the adjustment range of the temperature adjustment parameters, wherein different preset temperature ranges are positively correlated with the maximum temperature adjustment parameter of the target adjustment range.
[0009] This invention first determines the target temperature range corresponding to the initial temperature. Based on a preset correspondence, different temperature ranges are negatively correlated with target temperatures; for example, a higher initial temperature corresponds to a slightly lower target temperature. This adapts to different initial environments and prevents overheating caused by a high target temperature when the initial temperature is high, or difficulty in inducing stable discharge when the initial temperature is low. Simultaneously, different temperature ranges correspond to the maximum parameter of the target adjustment range that is positively correlated. A larger adjustment parameter is used to enhance cooling capability when the initial temperature is high, while an adaptive parameter is used to avoid over-adjustment when the initial temperature is low. This further improves the accuracy of temperature control, ensuring that subsequent staged control is more aligned with actual needs and guarantees stable glow discharge.
[0010] In one optional implementation, the first operating parameter, the second operating parameter, and the third operating parameter all include the AC power supply voltage of the glow discharge component, and the AC power supply voltages corresponding to the first operating parameter, the second operating parameter, and the third operating parameter decrease sequentially.
[0011] This invention addresses the issue of requiring a high power supply voltage for startup in the first, second, and third operating parameters. By using a higher voltage for the first operating parameter during the glow discharge device's startup phase, sufficient energy is provided to excite the glow discharge in a cold state (e.g., immediately after power-on), solving the problem of needing a high power supply amplitude for startup in a cold state and ensuring smooth startup of the glow discharge component. The second operating parameter, used during the adjustment phase, lowers the voltage to avoid excessive discharge and rapid temperature rise caused by continuously high voltage. The third operating parameter, used during the temperature maintenance phase, has the lowest voltage, allowing for reduced energy input after temperature stabilization and preventing temperature fluctuations caused by excess energy. This gradual voltage reduction adapts to the temperature requirements of different stages, ensuring successful startup of the glow discharge component while avoiding excessive temperature or energy waste, further optimizing thermal stability control and ensuring continuous and stable glow discharge.
[0012] In one optional implementation, reducing the temperature regulation parameter of the temperature regulation device includes: starting from the maximum temperature regulation parameter, reducing the temperature regulation parameter by a preset regulation parameter adjustment amount in each adjustment cycle.
[0013] This invention starts with the maximum temperature adjustment parameter and decreases the parameter by a preset amount in each adjustment cycle. This gradual temperature adjustment process avoids insufficient or excessive temperature regulation caused by sudden parameter drops. The preset adjustment amount can be set according to equipment characteristics and temperature control requirements, ensuring that each adjustment accurately approaches the target temperature and reduces temperature fluctuations. This orderly parameter adjustment method improves the controllability and stability of temperature regulation, laying a solid foundation for subsequent temperature maintenance stages and ensuring a stable glow discharge environment.
[0014] In one optional implementation, adjusting the temperature regulation parameter of the temperature regulating device based on the relationship between the current ambient temperature and the target temperature includes: decreasing the current temperature regulation parameter of the temperature regulating device when the current ambient temperature is greater than the target temperature; and increasing the current temperature regulation parameter of the temperature regulating device when the current ambient temperature is less than the target temperature.
[0015] This invention adjusts temperature control parameters based on the relationship between the current temperature and the target temperature. When the current temperature is higher than the target temperature, the parameters are lowered to reduce the temperature control capability and prevent excessive temperature drop; conversely, when the current temperature is lower than the target temperature, the parameters are increased to enhance the control capability and prevent the temperature from continuing to fall. This bidirectional adjustment logic forms a closed-loop temperature control, which can correct temperature deviations in real time, ensuring that the temperature always fluctuates around the target temperature. This prevents excessive temperature deviation from causing discharge instability, further improving thermal stability and ensuring glow discharge performance.
[0016] In one optional implementation, reducing or increasing the current temperature regulation parameter of the temperature regulation device includes: reducing or increasing the temperature regulation parameter by a preset adjustment amount during the current adjustment cycle.
[0017] This invention reduces or increases parameters by a preset amount during the current adjustment cycle, ensuring a fixed and controllable adjustment range each time and preventing temperature fluctuations caused by arbitrary adjustments. The preset adjustment amount can be set based on the device's temperature regulation sensitivity. This standardized parameter adjustment method reduces the impact of human or random factors on temperature control, improves the consistency and accuracy of adjustment, ensures that the temperature remains stable within the target range, and provides a stable environment for glow discharge.
[0018] In an optional embodiment, the method further includes: after the glow discharge component stops working, controlling the temperature regulating device to maintain the current temperature regulating parameters for a second period of time, and then, in response to the parameter adjustment operation of the temperature regulating device, performing operation control on the temperature regulating device.
[0019] This invention allows the temperature control device to maintain its current parameters for a second period after the glow discharge module stops operating. This continues to regulate the temperature of the environment surrounding the module, preventing the module from overheating due to residual heat buildup after shutdown and exceeding the material's temperature resistance range, thus avoiding damage. The parameter adjustment operation after the second period ensures sufficient dissipation of residual heat and allows for flexible adjustment of the device's operating status according to actual needs, preventing energy waste. This design extends the temperature control cycle, covering the residual heat treatment stage after the glow discharge module stops operating, further protecting the module, extending the equipment's lifespan, and simultaneously achieving energy saving and practicality.
[0020] In an optional implementation, the method further includes: in response to the power-off operation of the glow discharge device, controlling the temperature regulating device to continue operating at the current temperature regulating parameter for a third duration and then stopping operation; during the third duration, in response to the power-on operation of the glow discharge device, controlling the temperature regulating device to operate at the maximum temperature regulating parameter for a fourth duration, and then, in response to the parameter adjustment operation of the temperature regulating device, performing operation control on the temperature regulating device.
[0021] This invention allows the temperature control device to maintain its current parameters for three hours after the equipment is shut down before stopping. This allows it to continue processing residual ambient heat after shutdown, preventing heat buildup that could damage components or internal parts due to high temperatures and ensuring equipment safety after shutdown. If the equipment is restarted within the third hour, it operates at maximum temperature control parameters for a fourth hour, quickly restoring its temperature control capabilities and compensating for short-term temperature fluctuations after shutdown. This prevents abnormal temperatures (such as undissipated residual heat or excessively low temperatures) from affecting glow discharge initiation upon restart, ensuring the components can initiate discharge at the appropriate temperature. This design covers both shutdown and restart scenarios, improves temperature control logic, and enhances the continuity and safety of equipment operation.
[0022] In one optional embodiment, the temperature regulating device is a fan, the temperature regulating parameter is the fan speed, and the fan is installed in the cavity where the glow discharge component is located to realize the exchange of gas inside and outside the cavity.
[0023] This invention employs a fan as a temperature regulation device, with the fan speed serving as the temperature regulation parameter. By placing the fan within the cavity of the glow discharge assembly, gas exchange is achieved, thus regulating the temperature. The fan removes heat from the cavity through gas exchange or introduces external gas at a suitable temperature to regulate the temperature, resulting in more uniform and efficient heat dissipation without generating excessive additional heat that could affect temperature control. The fan's placement within the cavity allows it to directly act on the surrounding environment of the assembly, shortening the temperature regulation response time and ensuring that temperature changes are quickly transmitted to the vicinity of the assembly, promptly correcting temperature deviations. Simultaneously, the fan speed parameter is easily and precisely controlled, allowing for adjustments to different heat dissipation intensities to meet the needs of staged temperature control, further optimizing thermal stability regulation and ensuring stable operation of the glow discharge assembly.
[0024] Secondly, the present invention provides a glow discharge control device applied to a glow discharge equipment. The glow discharge equipment includes a glow discharge component and a temperature regulation device. The glow discharge component is composed of a plurality of discharge electrodes. The device includes: an acquisition module, used to acquire the initial ambient temperature of the environment in which the glow discharge component is located, and to determine a target temperature and a target adjustment range of temperature regulation parameters based on the initial ambient temperature. The temperature regulation parameters are operating parameters of the temperature regulation device, used to adjust the ambient temperature of the environment in which the glow discharge component is located; and a first processing module, used to control the glow discharge component to operate with a first operating parameter, and to control the temperature regulation device to operate with the maximum temperature regulation parameter of the target adjustment range. The maximum temperature regulation parameter is... The temperature regulation parameter with the strongest ambient temperature regulation capability within the target regulation range; the second processing module is used to switch the glow discharge component to operate with the second operating parameter after the temperature regulation device has been running for a first period of time, and to reduce the temperature regulation parameter of the temperature regulation device until the current ambient temperature of the environment where the glow discharge component is located reaches the target temperature or the temperature regulation parameter of the temperature regulation device reaches the minimum temperature regulation parameter of the target regulation range, and then switch the glow discharge component to operate with the third operating parameter; the third processing module is used to adjust the temperature regulation parameter of the temperature regulation device based on the relationship between the current ambient temperature and the target temperature, so that the current ambient temperature is within the temperature range corresponding to the target temperature.
[0025] Thirdly, the present invention provides a glow discharge device, comprising: a glow discharge assembly, the glow discharge assembly being composed of a plurality of discharge electrodes, the glow discharge device further comprising: a temperature regulating device for regulating the ambient temperature of the environment in which the glow discharge assembly is located; and a controller comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the glow discharge control method of the first aspect or any corresponding embodiment described above.
[0026] This invention relates to a glow discharge device comprising a temperature regulating device and a controller. The temperature regulating device provides hardware support for temperature control and can directly act on the environment in which the glow discharge component is located to achieve temperature regulation. The controller enables precise and automatic execution of the glow discharge control method, avoiding errors and delays from manual operation, and achieving real-time and dynamic temperature control. This solves the thermal stability problem of the glow discharge process, ensures continuous and stable glow discharge, and improves the overall performance and reliability of the equipment.
[0027] In one optional embodiment, the temperature regulating device is a fan, and the temperature regulating parameter is the fan speed. The fan is installed in the cavity where the glow discharge component is located to realize the exchange of gas inside and outside the cavity.
[0028] This invention employs a fan as a temperature regulation device, with the fan speed serving as the temperature regulation parameter. By placing the fan within the cavity of the glow discharge assembly, gas exchange is achieved, thus regulating the temperature. The fan removes heat from the cavity through gas exchange or introduces external gas at a suitable temperature to regulate the temperature, resulting in more uniform and efficient heat dissipation without generating excessive additional heat that could affect temperature control. The fan's placement within the cavity allows it to directly act on the surrounding environment of the assembly, shortening the temperature regulation response time and ensuring that temperature changes are quickly transmitted to the vicinity of the assembly, promptly correcting temperature deviations. Simultaneously, the fan speed parameter is easily and precisely controlled, allowing for adjustments to different heat dissipation intensities to meet the needs of staged temperature control, further optimizing thermal stability regulation and ensuring stable operation of the glow discharge assembly.

Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0032] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.
[0033] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0034] Figure 1 is a schematic diagram of the glow discharge device. As shown in Figure 1, the glow discharge device includes: a glow discharge component 101, which is composed of several discharge electrodes; a temperature regulating device 102, used to regulate the ambient temperature of the environment in which the glow discharge component is located; and a controller 103, used to execute a glow discharge control method to control the glow discharge of the glow discharge component 101 and to control the operation of the temperature regulating device 102. The specific process of the controller 103 executing the glow discharge control method is detailed in the relevant description of the method embodiments below, and will not be repeated here.
[0035] The glow discharge device provided in this embodiment includes a temperature regulation device and a controller. The temperature regulation device provides hardware support for temperature control and can directly act on the environment where the glow discharge component is located to achieve temperature regulation. The controller enables precise automatic execution of the glow discharge control method, avoiding errors and delays from manual operation, and achieving real-time and dynamic temperature control. This solves the thermal stability problem of the glow discharge process, ensures continuous and stable glow discharge, and improves the overall performance and reliability of the equipment.
[0036] Specifically, the temperature regulating device 102 is a fan, the temperature regulating parameter is the fan speed, and the fan is installed in the cavity where the glow discharge component 101 is located to realize the exchange of gas inside and outside the cavity.
[0037] This embodiment uses a fan as the temperature regulation device, with the fan speed serving as the temperature regulation parameter. By placing the fan within the cavity of the glow discharge module, gas exchange is achieved, thus regulating the temperature. The fan removes heat from the cavity through gas exchange or introduces external gas at a suitable temperature to regulate the temperature, resulting in more uniform and efficient heat dissipation without generating excessive additional heat that could affect temperature control. The fan's placement within the cavity directly impacts the surrounding environment, shortening the temperature regulation response time and ensuring that temperature changes are quickly transmitted to the vicinity of the module, allowing for timely correction of temperature deviations. Simultaneously, the fan speed parameter is easily and precisely controlled, allowing for adjustments to different heat dissipation intensities to meet the needs of phased temperature control, further optimizing thermal stability regulation and ensuring stable operation of the glow discharge module.
[0038] It should be noted that in practical applications, the temperature regulating device 102 mentioned above can also be other devices with temperature regulating functions, such as a refrigerator. Accordingly, the temperature regulating parameter is the refrigeration power of the refrigerator. This is just an example, and the present invention is not limited thereto.
[0039] In practical applications, the above-mentioned glow discharge device also includes a temperature detection device, such as a temperature sensor such as a temperature sensing bulb. The temperature sensing bulb can be set in the environment where the glow discharge component 101 is located to collect the ambient temperature of the environment where the glow discharge component 101 is located and send it to the controller 103. This is just an example, and the present invention is not limited thereto.
[0040] For example, Figure 2 is a schematic diagram of the glow discharge assembly. As shown in Figure 2, the glow discharge assembly is composed of multiple discharge electrodes connected together. In Figure 2, end A connects the built-in metal electrodes 201 of each discharge electrode together, and end B connects the spiral tungsten filaments 202 of each discharge electrode together. High-voltage AC power is applied to ends A and B. A temperature sensing bulb 203 is placed near the center of the glow discharge assembly, positioned close to the glow discharge point of the tungsten filaments. In this embodiment, only one temperature sensing bulb 203 is used as an example. In practical applications, the number of temperature sensing bulbs 203 can be increased or decreased according to actual needs. The average temperature measured by each temperature sensing bulb 203 can be used as the ambient temperature of the environment where the glow discharge assembly 101 is located.
[0041] Since glow discharge modules can effectively address the ionization instability problem through structural and material selection, thermal factors significantly influence the intensity of the glow discharge. It should be noted that glow discharge itself generates considerable heat, resulting in high temperatures around the glow discharge module. At moderate temperatures (40-70℃), glow discharge is relatively stable; at higher temperatures (80℃), the positive feedback mechanism (a decrease in neutral particle number density leading to enhanced discharge, which further increases gas temperature, forming a positive feedback mechanism) accelerates significantly, causing the temperature to rise rapidly and eventually reach the material's temperature limit, leading to material failure. In a cold state (e.g., when the electrodes are just energized), a power supply amplitude significantly higher than that required for stable operation is needed to trigger glow discharge.
[0042] To address this issue, this invention proposes a glow discharge control scheme. By controlling the operating parameters of the glow discharge component and the parameters of the temperature regulation device, the scheme ensures that the electrode operates in accordance with the characteristics of glow discharge, thus solving the thermal stability problem of glow discharge. This avoids weak or non-existent glow discharge, which could affect performance, or overheating of the glow discharge, causing irreversible damage and electrode failure, thereby improving the operational stability of the glow discharge device.
[0043] According to an embodiment of the present invention, a glow discharge control method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0044] This embodiment provides a glow discharge control method, which can be used in the controller of glow discharge equipment such as a microcontroller or MCU. Figure 3 is a flowchart of the glow discharge control method according to an embodiment of the present invention. As shown in Figure 3, the process includes the following steps: Step S301, obtain the initial ambient temperature of the environment where the glow discharge component is located, and determine the target temperature and the target adjustment range of the temperature adjustment parameters based on the initial ambient temperature.
[0045] Among them, the temperature regulation parameter is the operating parameter of the temperature regulation equipment, which is used to regulate the ambient temperature of the environment in which the glow discharge component is located.
[0046] Specifically, the initial ambient temperature can be obtained by continuously detecting the average temperature for 10 seconds using multiple temperature sensors located at the center of the glow discharge component (e.g., near the tungsten filament glow discharge point). For example, taking the aforementioned fan as the temperature regulation component, the corresponding temperature regulation parameter is the fan speed. Adjusting the fan speed changes the airflow speed in the environment surrounding the glow discharge component, thereby regulating the ambient temperature. The higher the speed, the stronger the ambient temperature regulation capability (and the better the heat dissipation effect). The larger the target regulation range, the larger the corresponding fan speed range. For example, the target regulation range of the fan speed could be 450-1150 revolutions per unit time, or 450-1250 revolutions per unit time, etc. This is merely an example, and the invention is not limited thereto.
[0047] Step S302: Control the glow discharge component to operate with the first operating parameter, and control the temperature regulation device to operate with the maximum temperature regulation parameter of the target regulation range.
[0048] Among them, the maximum temperature regulation parameter is the temperature regulation parameter with the strongest ability to regulate the ambient temperature within the target regulation range. The first operating parameter is the operating parameter required for the glow discharge component to perform glow discharge, which may specifically include: the voltage and frequency of the alternating current applied to the two ends of the electrodes of the glow discharge component. For example, in Figure 2, 3.8KV alternating current is applied to the AB ends, and the frequency range of the alternating current is 10Khz~100Khz. This is just an example, and the present invention is not limited thereto.
[0049] For example, continuing with the above-mentioned fan, the maximum temperature regulation parameter of the target adjustment range is the maximum value of the target speed range of the fan in the corresponding temperature segment. This parameter is the parameter with the strongest ability to regulate ambient temperature within the target adjustment range. It can achieve rapid heat dissipation or assist in temperature stabilization through the maximum speed, laying the foundation for subsequent temperature regulation.
[0050] Step S303: After the temperature regulating device has been running for a first period of time, switch the glow discharge component to run with the second operating parameter, and reduce the temperature regulating parameter of the temperature regulating device until the current ambient temperature of the environment where the glow discharge component is located reaches the target temperature or the temperature regulating parameter of the temperature regulating device reaches the minimum temperature regulating parameter of the target regulating range, and then switch the glow discharge component to run with the third operating parameter.
[0051] The first duration refers to the time required for temperature acquisition and judgment after the glow discharge device is started, such as 10 minutes or 15 minutes. This is just an example and is not a limitation of the present invention. After the first duration is reached, the temperature adjustment stage begins. The second working parameter can be the same as or different from the first working parameter. For example, the AC voltage in the second working parameter can be appropriately reduced, such as to 3.5KV, while the frequency remains at 10kHz~100kHz. Subsequently, the temperature adjustment parameter (i.e., fan speed) of the temperature adjustment device (fan) is gradually reduced. The reduction process needs to be judged in conjunction with the current ambient temperature of the environment where the glow discharge component is located (still through the average temperature detected by each temperature sensor for 10 consecutive seconds) until one of the following two conditions is met: the current ambient temperature reaches the target temperature determined in step S301; or the fan speed is reduced to the minimum temperature adjustment parameter (i.e., the minimum value of the target speed range) within the target adjustment range determined in step S301. Once any of the above conditions are met, the operating parameters of the glow discharge component need to be switched again, from the second operating parameter to the third operating parameter. For example, the third operating parameter is to apply 3.2KV AC power to both ends of the glow discharge component and maintain the frequency at 10Khz~100Khz.
[0052] Step S304: Adjust the temperature regulation parameters of the temperature regulation device based on the relationship between the current ambient temperature and the target temperature, so that the current ambient temperature is within the temperature range corresponding to the target temperature.
[0053] Specifically, after the glow discharge module switches to the third operating parameter, it enters the temperature maintenance stage. Based on the relationship between the current ambient temperature and the target temperature of the environment where the glow discharge module is located, the temperature regulation parameters (speed) of the temperature regulation equipment (fan) need to be dynamically adjusted to ensure that the current ambient temperature is always within the temperature range corresponding to the target temperature (such as the target temperature ±2℃).
[0054] This embodiment first obtains the initial ambient temperature of the glow discharge module, determines the suitable target temperature and the target adjustment range of the temperature regulation parameters, ensuring the accuracy of temperature control and avoiding subsequent temperature runaway due to improper initial parameters. Controlling the glow discharge module with the first operating parameter and the temperature regulation device with the maximum parameter allows the module to quickly enter the working state and efficiently regulate the ambient temperature, shortening the start-up time. After the first period of operation, the module is switched to the second operating parameter, while the temperature regulation parameter is reduced to prevent the temperature from rising too quickly and exceeding the normal glow discharge temperature range of the module. Once the temperature reaches the target or the parameter reaches its minimum value, the module is switched to the third operating parameter, and the parameter is adjusted according to the temperature relationship to stably maintain the ambient temperature within the target range. This phased dynamic adjustment method effectively solves the thermal stability problem of glow discharge, preventing weak discharge from affecting performance or overheating from causing glow discharge module failure, ensuring the stable and efficient operation of the entire glow discharge equipment.
[0055] This embodiment provides a glow discharge control method, which can be used in the controller of glow discharge equipment such as a microcontroller or MCU. Figure 4 is a flowchart of the glow discharge control method according to an embodiment of the present invention. As shown in Figure 4, the process includes the following steps: Step S401, obtain the initial ambient temperature of the environment where the glow discharge component is located, and determine the target temperature and the target adjustment range of the temperature adjustment parameters based on the initial ambient temperature. The temperature adjustment parameters are the operating parameters of the temperature adjustment equipment, which are used to adjust the ambient temperature of the environment where the glow discharge component is located.
[0056] For example, the temperature regulating device is a fan, the temperature regulating parameter is the fan speed, and the fan is installed in the cavity where the glow discharge component is located to realize the exchange of gas inside and outside the cavity.
[0057] This embodiment uses a fan as the temperature regulation device, with the fan speed serving as the temperature regulation parameter. By placing the fan within the cavity of the glow discharge module, gas exchange is achieved, thus regulating the temperature. The fan removes heat from the cavity through gas exchange or introduces external gas at a suitable temperature to regulate the temperature, resulting in more uniform and efficient heat dissipation without generating excessive additional heat that could affect temperature control. The fan's placement within the cavity directly impacts the surrounding environment, shortening the temperature regulation response time and ensuring that temperature changes are quickly transmitted to the vicinity of the module, allowing for timely correction of temperature deviations. Simultaneously, the fan speed parameter is easily and precisely controlled, allowing for adjustments to different heat dissipation intensities to meet the needs of phased temperature control, further optimizing thermal stability regulation and ensuring stable operation of the glow discharge module.
[0058] Specifically, the step S401 above, which determines the target temperature and the target adjustment range of the temperature adjustment parameters based on the initial ambient temperature, includes: step a1, determining the target temperature range corresponding to the initial ambient temperature.
[0059] Specifically, after obtaining the initial ambient temperature, a preset temperature range is defined based on this initial ambient temperature. Each preset temperature range is the target temperature range corresponding to the initial ambient temperature. In practical applications, the division of preset temperature ranges needs to be combined with the thermal stability characteristics of glow discharge to ensure that the subsequent matching target temperature and adjustment parameters can adapt to the discharge requirements under different initial temperature scenarios.
[0060] In this embodiment, the preset temperature range (i.e., the target temperature range) is divided into the following five segments: First preset temperature range: initial ambient temperature (internal average temperature) < 0℃; Second preset temperature range: 0℃ ≤ initial ambient temperature ≤ 10℃; Third preset temperature range: 10℃ < initial ambient temperature ≤ 20℃; Fourth preset temperature range: 20℃ < initial ambient temperature ≤ 30℃; Fifth preset temperature range: initial ambient temperature > 30℃. Example: If the initial average temperature of the environment where the glow discharge component is located is 25℃ after continuous detection by the temperature sensor for 10 seconds, this temperature falls within the range of "20℃ < initial ambient temperature ≤ 30℃". Therefore, the target temperature range corresponding to this initial ambient temperature is determined to be the fourth preset temperature range. This is only an example, and the present invention is not limited to this.
[0061] Step a2: Based on the correspondence between the preset temperature range and the target temperature, determine the target temperature corresponding to the target temperature range.
[0062] Among them, different preset temperature ranges are negatively correlated with the target temperature. That is, the higher the preset temperature range of the initial ambient temperature (the higher the initial ambient temperature), the lower the corresponding target temperature. The purpose is to adapt to the thermal stability requirements of glow discharge: when the initial temperature is high, if the target temperature is too high, it is easy to trigger the positive feedback mechanism of thermal instability; when the initial temperature is low, a slightly higher target temperature is required to ensure stable excitation of glow discharge, thereby improving the thermal stability of glow discharge.
[0063] For example, the target temperature corresponding to the first preset temperature range (initial temperature < 0℃) is 55℃ (allowing a fluctuation of ±2℃, i.e., the target temperature range is 53℃-57℃); the target temperature corresponding to the fifth preset temperature range (initial temperature > 30℃) is 51℃ (allowing a fluctuation of ±2℃, i.e., the target temperature range is 49℃-53℃). This is merely an example, and the present invention is not limited thereto.
[0064] Step a3: Based on the relationship between the preset temperature range and the adjustment range of the temperature adjustment parameters, determine the target adjustment range corresponding to the target temperature range.
[0065] Among them, the maximum temperature regulation parameter of different preset temperature ranges and target regulation ranges is positively correlated. That is, the higher the preset temperature range to which the initial ambient temperature belongs (the higher the initial ambient temperature), the greater the maximum speed of the fan in the target regulation range. This allows for a stronger temperature regulation capability (the heat dissipation effect of higher speed) to balance the impact of the initial high temperature environment on the stability of glow discharge.
[0066] For example, in the first preset temperature range (initial temperature < 0℃), the target adjustment range is 450-1150 rpm, and the maximum temperature adjustment parameter (maximum speed) is 1150 rpm; in the second preset temperature range (0℃ ≤ initial temperature ≤ 10℃), the target adjustment range is 450-1250 rpm, and the maximum temperature adjustment parameter (maximum speed) is 1250 rpm. This is merely an example, and the present invention is not limited thereto.
[0067] This embodiment first determines the target temperature range corresponding to the initial temperature. Based on a preset correspondence, different temperature ranges are negatively correlated with the target temperature; for example, a higher initial temperature corresponds to a slightly lower target temperature. This adapts to different initial environments and prevents overheating caused by a high target temperature when the initial temperature is high, or difficulty in inducing stable discharge when the initial temperature is low. Simultaneously, different temperature ranges correspond to the maximum parameter of the target adjustment range that is positively correlated. A larger adjustment parameter is used to enhance cooling capability when the initial temperature is high, while an appropriate parameter is used to avoid over-adjustment when the initial temperature is low. This further improves the accuracy of temperature control, ensuring that subsequent staged control better meets actual needs and guarantees stable glow discharge.
[0068] Step S402: Control the glow discharge component to operate with the first operating parameter, and control the temperature regulation device to operate with the maximum temperature regulation parameter within the target regulation range. The maximum temperature regulation parameter is the temperature regulation parameter with the strongest ambient temperature regulation capability within the target regulation range. For details, please refer to the relevant description of step S302 shown in Figure 3, which will not be repeated here.
[0069] Step S403: After the temperature regulating device has been running for a first period of time, switch the glow discharge component to run with the second operating parameter, and reduce the temperature regulating parameter of the temperature regulating device until the current ambient temperature of the environment where the glow discharge component is located reaches the target temperature or the temperature regulating parameter of the temperature regulating device reaches the minimum temperature regulating parameter of the target regulating range, and then switch the glow discharge component to run with the third operating parameter.
[0070] The first operating parameter, the second operating parameter, and the third operating parameter all include the AC power supply voltage of the glow discharge component, and the AC power supply voltage corresponding to the first operating parameter, the second operating parameter, and the third operating parameter decreases sequentially.
[0071] This embodiment achieves this by sequentially decreasing the AC power supply voltage of the first, second, and third operating parameters. By using a higher voltage for the first operating parameter during the glow discharge device's startup phase, sufficient energy is provided to excite the glow discharge in a cold state (e.g., immediately after power-on), solving the problem of requiring a high power supply amplitude for startup in a cold state and ensuring smooth startup of the glow discharge component. The second operating parameter, used during the adjustment phase, lowers the voltage to avoid excessive discharge and rapid temperature rise caused by continuously high voltage. The third operating parameter, used during the temperature maintenance phase, has the lowest voltage, allowing for reduced energy input after temperature stabilization and preventing excess energy from causing temperature fluctuations. This gradual voltage reduction adapts to the temperature requirements of different stages, ensuring successful startup of the glow discharge component while avoiding excessive temperature or energy waste, further optimizing thermal stability control and ensuring continuous and stable glow discharge.
[0072] Specifically, the step S403 above, which involves reducing the temperature regulation parameter of the temperature regulation device, includes: step b1, starting from the maximum temperature regulation parameter, reducing the temperature regulation parameter by a preset adjustment amount in each adjustment cycle.
[0073] Specifically, by starting with the maximum temperature adjustment parameter within the target adjustment range, and gradually reducing the parameter by combining a fixed adjustment cycle and a preset adjustment parameter amount, the ambient temperature of the glow discharge module is ensured to steadily approach the target temperature, laying the foundation for subsequent stable operation.
[0074] The adjustment cycle is a pre-set time interval used to determine whether to reduce the temperature regulation parameter, and the adjustment cycle varies in different scenarios. The preset regulation parameter adjustment amount is a pre-set fixed magnitude for each reduction of the temperature regulation parameter, and it also varies with the scenario. Specifically, the current ambient temperature of the environment where the glow discharge component is located can be determined, and then the corresponding adjustment cycle and preset regulation parameter adjustment amount can be determined based on the current ambient temperature. For example, if the current ambient temperature is <50℃, the adjustment cycle is set to 2 minutes, and the preset regulation parameter adjustment amount is set to 50 revolutions per minute, that is, the fan speed is reduced by 50 revolutions per minute every 2 minutes; if the current ambient temperature is ≥50℃, the adjustment cycle is set to 3 minutes, and the preset regulation parameter adjustment amount is set to 25 revolutions per minute, that is, the fan speed is reduced by 25 revolutions per minute every 3 minutes. The entire adjustment process must start from the maximum temperature regulation parameter and gradually reduce the temperature regulation parameter according to the adjustment cycle and adjustment amount of the corresponding scenario until the condition for stopping the parameter reduction is met (i.e., the current ambient temperature reaches the target temperature or the temperature regulation parameter drops to the minimum temperature regulation parameter within the target adjustment range).
[0075] In practical applications, to ensure the accuracy of the judgment on stopping parameter reduction, when the current ambient temperature reaches the target temperature or the temperature adjustment parameter drops to the minimum temperature adjustment parameter within the target adjustment range, the system can continue to run at the current temperature adjustment parameter for one adjustment cycle. If the stopping condition is met again, subsequent steps can be executed. For example, when the average temperature is greater than or equal to the target temperature or the fan speed reaches the minimum of the segment, wait for another adjustment cycle, such as 3 minutes or 2 minutes, before entering the temperature maintenance stage.
[0076] This embodiment starts with the maximum temperature adjustment parameter and decreases the parameter by a preset amount in each adjustment cycle. This gradual temperature adjustment process avoids insufficient or sudden temperature increases caused by abrupt parameter drops. The preset adjustment amount can be set according to equipment characteristics and temperature control requirements, ensuring that each adjustment accurately approaches the target temperature and reduces temperature fluctuations. This orderly parameter adjustment method improves the controllability and stability of temperature regulation, laying a solid foundation for the subsequent temperature maintenance stage and ensuring a stable glow discharge environment.
[0077] Step S404: Adjust the temperature regulation parameters of the temperature regulation device based on the relationship between the current ambient temperature and the target temperature, so that the current ambient temperature is within the temperature range corresponding to the target temperature.
[0078] Specifically, in step S404 above, the temperature regulation parameter of the temperature regulation device is adjusted based on the relationship between the current ambient temperature and the target temperature, including: step c1, when the current ambient temperature is greater than the target temperature, the current temperature regulation parameter of the temperature regulation device is reduced.
[0079] Specifically, when the current ambient temperature is detected to be higher than the target temperature (excluding fluctuations within ±2℃ of the target temperature, i.e., the current temperature exceeds the upper limit of the target temperature), it indicates that the ambient temperature of the glow discharge module is too high. The heat dissipation capacity needs to be reduced by decreasing the current temperature regulation parameter (fan speed) of the temperature regulation equipment to prevent further temperature increases and the triggering of thermal instability. The adjustment process must follow the adjustment cycle and single adjustment range for the corresponding temperature scenario: every adjustment cycle, the current fan speed is reduced by the single adjustment range until the current ambient temperature falls back to the range corresponding to the target temperature (target temperature ±2℃). At this point, the parameter reduction is stopped, and the current speed is maintained.
[0080] Step c2: When the current ambient temperature is lower than the target temperature, increase the current temperature regulation parameter of the temperature regulation device.
[0081] Specifically, when the current ambient temperature is detected to be lower than the target temperature (excluding fluctuations within ±2℃ of the target temperature, i.e., the current temperature is below the lower limit of the target temperature), it indicates that the ambient temperature of the glow discharge component is too low, which may lead to a weakening or even interruption of the glow discharge intensity. In this case, it is necessary to increase the current temperature regulation parameter (fan speed) of the temperature regulation device to enhance heat dissipation (increasing the speed here can assist temperature balance through airflow, preventing the temperature from remaining persistently low), thus causing the temperature to rise back to the target range. The adjustment process can follow the adjustment cycle and single adjustment range corresponding to the temperature scenario: every adjustment cycle, increase the current fan speed by the single adjustment range until the current ambient temperature rises to the range corresponding to the target temperature (target temperature ±2℃). At this point, stop increasing the parameter and maintain the current speed.
[0082] It should be noted that during the parameter increase process, it is necessary to ensure that the final speed does not exceed the target adjustment range determined in step a3 above (i.e., the upper limit of the speed does not exceed the maximum temperature adjustment parameter of the target adjustment range, and the lower limit is not lower than the minimum temperature adjustment parameter of the target adjustment range). If the speed will exceed the upper limit of the target adjustment range after the increase, then only adjust to the maximum speed to avoid equipment failure and other problems caused by parameters exceeding the range.
[0083] This embodiment adjusts the temperature control parameters based on the relationship between the current temperature and the target temperature. When the current temperature is higher than the target temperature, the parameters are lowered to reduce the temperature control capability and prevent excessive temperature drop; when the current temperature is lower than the target temperature, the parameters are increased to enhance the control capability and prevent the temperature from continuing to fall. This bidirectional adjustment logic forms a closed-loop temperature control, which can correct temperature deviations in real time, ensuring that the temperature always fluctuates around the target temperature. This avoids excessive temperature deviation that could cause discharge instability, further improving thermal stability and ensuring the glow discharge effect.
[0084] Furthermore, the temperature regulation parameter can be decreased or increased by a preset adjustment amount within the current adjustment cycle. The adjustment cycle and preset adjustment parameter amount are described above and will not be repeated here.
[0085] This embodiment lowers or increases parameters by a preset amount during the current adjustment cycle, ensuring that the adjustment range is fixed and controllable each time, thus avoiding temperature fluctuations caused by arbitrary adjustments. The preset adjustment amount can be set based on the device's temperature regulation sensitivity. This standardized parameter adjustment method reduces the impact of human or random factors on temperature control, improves the consistency and accuracy of adjustment, ensures that the temperature remains stable within the target range, and provides a stable environment for glow discharge.
[0086] Step S405: After the glow discharge component stops working, the temperature regulation device is controlled to maintain the current temperature regulation parameters for a second duration, and then the operation of the temperature regulation device is controlled in response to the parameter adjustment operation of the temperature regulation device.
[0087] Specifically, "glow discharge component stopping operation" means that the glow discharge component suspends its glow discharge function (e.g., the device is in standby mode or temporarily interrupted, not completely shut down). At this time, AC current is no longer applied to the electrodes of the glow discharge component, and the discharge process terminates. The current temperature regulation parameter is the real-time operating speed of the fan before the component stops operating. The second duration is a pre-set fixed duration for which the temperature regulation device needs to maintain the current operating speed after the component stops operating. The second duration can be flexibly set according to the heat dissipation requirements of the glow discharge component. In this embodiment, the second duration is set to 3 minutes, which is only an example and is not a limitation of the present invention. The above parameter adjustment operation refers to the user or equipment control system's instruction to adjust the operating parameters (fan speed) of the temperature regulation device (e.g., manually adjusting the speed through a gear switch, or the speed adjustment logic automatically triggered by the equipment).
[0088] For example, immediately upon the dissipation discharge assembly ceasing operation, the temperature regulation device is controlled to continue running at the current temperature regulation parameters (current rotation speed) prior to ceasing operation, and this operation must continue for a second duration (3 minutes). During these 3 minutes, the temperature regulation device maintains the current rotation speed, continuously running to dissipate the residual heat accumulated by the dissipation discharge assembly during operation, preventing residual high temperatures from causing the electrode material to exceed its temperature resistance limit and fail. After the 3-minute operation ends, the temperature regulation device releases the "maintain current parameters" lock. At this time, if a parameter adjustment operation is received (e.g., the user adjusts the rotation speed from 1100 rpm to 800 rpm via a gear switch), the device responds to the operation and controls the operation of the temperature regulation device according to the adjusted parameters. If no adjustment operation is received, the device operates according to the default rules (e.g., maintaining the current rotation speed or switching to standby speed).
[0089] In this embodiment, after the glow discharge module stops working, the temperature control device maintains its current parameters for a second period of time. This allows for continued temperature regulation of the environment surrounding the module, preventing the module from overheating due to residual heat buildup after shutdown and exceeding the material's temperature resistance range, which could cause damage. The response parameter adjustment after the second period ensures sufficient dissipation of residual heat and allows for flexible adjustment of the equipment's operating status according to actual needs, avoiding energy waste. This design extends the temperature control cycle, covering the residual heat treatment stage after the glow discharge module stops working, further protecting the module, extending the equipment's lifespan, and simultaneously achieving energy saving and practicality.
[0090] In step S406, in response to the shutdown operation of the glow discharge equipment, the temperature regulation equipment is controlled to maintain the current temperature regulation parameters and continue to run for three hours before stopping.
[0091] Specifically, the shutdown operation of the glow discharge equipment refers to the power outage of the entire machine or the triggering of a shutdown command. At this time, all functional modules of the glow discharge equipment (including glow discharge components, control systems, etc.) enter the shutdown state, and the glow discharge components permanently stop discharging (not a temporary pause). The aforementioned third duration is a pre-set fixed duration for which the temperature regulation equipment needs to maintain the current speed operation after shutdown. The third duration can be flexibly set in combination with the heat dissipation requirements and energy consumption balance after the entire machine is shut down. In this embodiment, the third duration is set to 3 minutes. This is only an example and the present invention is not limited thereto.
[0092] For example, upon receiving a shutdown operation from the glow discharge equipment, the glow discharge component immediately stops working (AC current is stopped being applied to the electrodes). However, the temperature control device does not shut down automatically; instead, it continues to operate at the current temperature control parameters (current rotation speed) before shutdown, and this operation must continue for a third duration (3 minutes). Within 3 minutes, the temperature control device continuously dissipates residual heat from the components and the equipment, preventing heat accumulation in the sealed environment after shutdown, which could damage the electrode materials or other components. After the 3-minute operation ends, the temperature control device automatically stops operating, entering the shutdown state synchronously with the glow discharge equipment.
[0093] In step S407, during the third time period, in response to the power-on operation of the glow discharge equipment, the temperature regulating equipment is controlled to run at the maximum temperature regulating parameter for the fourth time period, and in response to the parameter adjustment operation of the temperature regulating equipment, the operation control of the temperature regulating equipment is performed.
[0094] Specifically, the power-on operation refers to the user-triggered restart command of the glow discharge device; the maximum temperature adjustment parameter is the maximum rotation speed within the target adjustment range determined in step a3, corresponding to the preset temperature range of the initial ambient temperature (i.e., the parameter with the strongest ambient temperature adjustment capability within the target adjustment range); the aforementioned fourth duration is a pre-set fixed duration for which the temperature adjustment device needs to run at the maximum speed after restarting. The fourth duration can be flexibly set according to the need for rapid temperature balancing during restart. In this embodiment, the fourth duration is set to 3 minutes, which is only an example and is not limited to this invention; the parameter adjustment operation here is consistent with the definition in step S405, referring to the command to adjust the rotation speed of the temperature adjustment device.
[0095] In practical applications, two prerequisites must be met when executing step S407: first, it must be within the third duration of step S406 (not ending 3 minutes after shutdown); second, a power-on operation must be received. At this time, the glow discharge device must be started immediately (the glow discharge component prepares to resume discharge), and the temperature regulation device must be forced to switch to the maximum temperature regulation parameter (the maximum speed corresponding to the preset temperature range), and this "maximum speed operation" state must continue for a fourth duration (3 minutes). During these 3 minutes, even if a parameter adjustment operation is received (such as manual adjustment by the user), the operation is temporarily invalid, and the temperature regulation device always runs at the maximum speed, quickly balancing the internal temperature of the device through the strongest temperature regulation capability, creating conditions for the glow discharge component to resume stable discharge; after the 3 minutes of operation ends, the temperature regulation device releases the "forced maximum speed" lock state, and then responds to subsequent parameter adjustment operations, operating according to the adjusted parameters.
[0096] In this embodiment, after the equipment is shut down, the temperature regulation device maintains its current parameters for three hours before stopping. This allows it to continue processing residual ambient heat after shutdown, preventing heat buildup that could damage components or internal parts due to high temperatures and ensuring equipment safety after shutdown. If the equipment is restarted within the third hour, it operates at maximum temperature regulation parameters for a fourth hour, quickly restoring its temperature regulation capability and compensating for short-term temperature fluctuations after shutdown. This prevents abnormal temperatures (such as undissipated residual heat or excessively low temperatures) from affecting glow discharge initiation upon restart, ensuring the components can initiate discharge at the appropriate temperature. This design covers both shutdown and restart scenarios, improves temperature control logic, and enhances the continuity and safety of equipment operation.
