Description

Technical Field

[0001] The invention relates to the technical field of chemical reaction engineering, and in particular to a method, device, equipment and medium for controlling hydrogen peroxide preparation conditions. Background Art

[0002] High voltage electric field plays an important role in the production of H2O2, but it has certain requirements for humidity, because too high or too low humidity will affect the stability and effect of high voltage electric field. At the same time, free electrons, neutral particles and negatively charged particles in the high voltage electric field will react with hydroxyl radicals and H2O2, resulting in a decrease in the concentration of hydroxyl radicals and H2O2 and a shortened survival time.

[0003] Traditional high-voltage electric fields use voltage and spacing to control safe distances and match safe output voltage parameters. However, the above parameters are not suitable for preparing hydrogen peroxide in high humidity environments, which can easily lead to low efficiency in the preparation of hydrogen peroxide solutions or aerosols. Summary of the invention

[0004] In view of this, the present invention provides a method for controlling hydrogen peroxide preparation conditions to solve the problem of low hydrogen peroxide preparation efficiency in a high humidity environment.

[0005] In a first aspect, the present invention provides a method for controlling the conditions for preparing hydrogen peroxide, the method comprising: S1: determining the current environmental state of preparing hydrogen peroxide by acquiring data collected by a humidity sensor; S2: when it is determined that the environmental state is not a high humidity environment, turning on a humidifying device and turning off the output state of a high-voltage package; when it is determined that the environmental state is a high humidity environment, controlling the high-voltage package to output a voltage according to a preset voltage value; S3: acquiring a first current signal of an environmental space collected by a current sensor, and determining, according to the first current signal, whether the state of air conductivity is an adjustment state, an insufficient state, or an excess state; if the air conductivity is an insufficient state, controlling the output voltage of a positive ion generator to increase according to a preset voltage value; if the air conductivity is an adjustment state, controlling the output voltage of a positive ion generator to increase according to a preset voltage value; If the air conductivity is in an excessive state, the positive ion generator is kept in the current output voltage state, and the high-voltage package is kept in the current state; if the air conductivity is in an excessive state, the positive ion generator is turned off, and the output voltage of the high-voltage package is controlled; S4: a second current signal of the ambient space collected by the current sensor is obtained, and the air conductivity state is determined to be a qualified state or an unqualified state according to the second current signal; if the air conductivity is in a qualified state, the current output voltage state of the positive ion generator is kept, the output voltage of the high-voltage package is controlled, and step S4 is repeated; if the air conductivity is in an unqualified state, the current output voltage state of the positive ion generator is kept, the output voltage of the high-voltage package is turned off, and step S3 is entered; the above operations S1 to S4 are repeated until the power is turned off or the machine reports an error and the power supply stops.

[0006] The embodiment of the present invention determines the current environmental state of hydrogen peroxide preparation by acquiring data collected by the humidity sensor, controls the state of the humidifier, keeps the humidifier in the open state in a high humidity environment, and controls the output voltage of the high-voltage package according to a preset voltage value to maintain an appropriate humidity level. The state of air conductivity is determined by first determining whether the air conductivity is insufficient, adjusted, or excessive, and taking corresponding control measures according to the judgment result, and then determining whether the air conductivity is qualified or unqualified. After the result is determined, a cyclic adjustment is performed, and the operation is repeated continuously to achieve precise control of humidity and air conductivity, and ensure that the air conductivity meets the requirements for preparing hydrogen peroxide in a high humidity environment, thereby effectively improving the production efficiency of hydrogen peroxide.

[0007] In an optional embodiment, the method of determining the current environmental state for preparing hydrogen peroxide by acquiring data collected by a humidity sensor includes: collecting an environmental space humidity signal through a humidity sensor to obtain an actual humidity value of the environment; if the actual humidity value is greater than a preset humidity threshold, determining it to be a high humidity environment; if the actual humidity value is less than or equal to the preset humidity threshold, determining it to be a non-high humidity environment.

[0008] By collecting the humidity signal of the ambient space and comparing it with the preset humidity threshold, changes in the ambient humidity can be sensed in a timely manner, thereby helping to more accurately determine whether the current space is in a high humidity environment, and helping to make adjustments as needed to maintain stable humidity conditions for hydrogen peroxide preparation.

[0009] In an optional embodiment, determining the air conductivity state according to the first current signal includes: converting the current signal into an actual current value i1; if the actual current value i1 is less than or equal to 0.75i0, determining that the air conductivity is in an insufficient state; if the actual current value i1 is greater than 0.75i0 and less than or equal to 1.25i0, determining that the air conductivity is in an adjustment state; if the actual current value i1 is greater than 1.25i0, determining that the air conductivity is in an excess state.

[0010] By converting the current signal into the actual current value i1 and comparing it with the preset current value i0, the state of the air conductivity is accurately determined. The air conductivity is judged to be insufficient, adjusted or excessive, thereby providing a more accurate basis for judgment and facilitating more precise adjustment of the state of the positive ion generator or high-voltage package in the subsequent cycle process.

[0011] In an optional embodiment, the determining of the air conductivity state according to the second current signal includes: converting the current signal into an actual current value i2; if the actual current value i2 is greater than the standard current value i0, determining that the air conductivity is in a qualified state; if the actual current value i2 is less than or equal to the standard current value i0, determining that the air conductivity is in an unqualified state. The standard current value i0 represents the current value collected when the high-voltage package output voltage and the high-voltage electrode spacing reach the critical condition of breakdown.

[0012] By converting the current signal into the actual current value i2 and comparing it with the preset current standard value i0, the qualified and unqualified states of the air conductivity can be accurately determined, the two states can be directly divided, the acceptability of the air conductivity can be quickly judged, and the next control operation can be intuitively determined, whether to maintain the current state or continue the cycle adjustment.

[0013] In an optional embodiment, after determining the state of air conductivity according to the current signal, it also includes: when the air conductivity is determined to be insufficient for a preset number of consecutive times, the machine reports an error and stops powering on.

[0014] When the air conductivity is determined to be insufficient for a preset number of times, the power supply is stopped, that is, when the air conductivity is continuously determined to be insufficient, the power supply to the entire system is stopped and an error is reported, thereby ensuring fault detection and protection of the device, and then timely discovering and solving problems with the positive ion generator.

[0015] In an optional embodiment, after determining the current environmental state for preparing hydrogen peroxide by acquiring data collected by the humidity sensor, the process further includes: repeating the above operation of determining the current environmental state by acquiring data collected by the humidity sensor according to a preset collection time period, and if the environmental state is determined to be a non-high humidity environment for a preset number of consecutive times, the machine reports an error and stops supplying power.

[0016] When the environmental state is determined to be a non-high humidity environment for a preset number of consecutive times, the power supply is stopped, that is, when it is continuously determined to be a non-high humidity environment, the power supply of the entire system is stopped and an error is reported, thereby ensuring fault detection and device protection, timely discovering and solving problems with the humidification device, ensuring system operation and saving resources, and thus ensuring that hydrogen peroxide can be prepared under high humidity conditions.

[0017] In a second aspect, the present invention provides a device for controlling conditions for preparing hydrogen peroxide, the device comprising:

[0018] A humidity control module, used to determine the current environmental state of preparing hydrogen peroxide by acquiring data collected by a humidity sensor;

[0019] The voltage setting module is used to turn on the humidification device and turn off the high-voltage package output state when the environmental state is determined to be a non-high-humidity environment; when the environmental state is determined to be a high-humidity environment, control the high-voltage package to output voltage according to a preset voltage value;

[0020] The first preparation condition control module is used to obtain the first current signal of the current sensor acquisition environment space, and determine whether the air conductivity state is an adjustment state, an insufficient state or an excessive state according to the first current signal; if the air conductivity is an insufficient state, the output voltage of the positive ion generator is controlled to increase according to a preset voltage value; if the air conductivity is an adjustment state, the current output voltage state of the positive ion generator is maintained, and the current state of the high-voltage package is maintained; if the air conductivity is an excessive state, the positive ion generator is turned off and the output voltage of the high-voltage package is controlled;

[0021] The second preparation condition control module is used to obtain the second current signal of the current sensor collecting environment space, and determine whether the air conductivity state is qualified or unqualified according to the second current signal; if the air conductivity is qualified, the current output voltage state of the positive ion generator is maintained, and the output voltage of the high-voltage package is controlled; if the air conductivity is unqualified, the current output voltage state of the positive ion generator is maintained, and the output voltage of the high-voltage package is turned off; until the power is turned off or the machine reports an error and the power supply stops.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] A method for controlling the preparation conditions of hydrogen peroxide provided in an embodiment of the present invention is applied to the scenario of generating H2O2 (hydrogen peroxide) for disinfection in a high humidity environment. When the humidifying device is working, the electrode is in a high humidity environment and there are excessive positively charged particles. In this case, the electrode will produce hydroxyl radicals and react with substances such as water to generate H2O2. Since H2O2 is soluble in water, small particles of H2O2 aqueous solution or H2O2 aerosol will be formed. H2O2 aerosol and the small particles of H2O2 aqueous solution formed are used to react with pollutants in the air, such as organic matter, odor substances, etc., so as to purify the air and improve the air quality.

[0032] According to an embodiment of the present invention, an embodiment of a method for controlling conditions for preparing hydrogen peroxide is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0033] In this embodiment, a method for controlling the preparation conditions of hydrogen peroxide is provided, which can be used in the above-mentioned computer device. Figure 1 : is a flow chart of a method for controlling the preparation conditions of hydrogen peroxide according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0034] Step S1, determining the current environmental state for preparing hydrogen peroxide by acquiring data collected by a humidity sensor.

[0035] In the embodiment of the present invention, the humidity sensor refers to a device for measuring the relative humidity in the environment, and judging the environmental state refers to judging whether the environmental humidity in the present invention reaches the environmental state for preparing hydrogen peroxide; it should be noted that a large number of positively charged ions can be generated by turning on the positive ion generator, the positive ion concentration in the air can be increased, and the air conductivity can be adjusted, and the air conductivity affects the preparation efficiency of hydrogen peroxide. It is also possible not to turn on the positive ion generator in the initial state, and adjust the air conductivity by controlling the state of the positive ion generator in subsequent cycles to save energy costs.

[0036] It is understandable that humidity is one of the important factors affecting the preparation of hydrogen peroxide. In a high humidity environment, the moisture content is high, which is conducive to the production of H2O2. Therefore, it is necessary to determine the current environmental state of hydrogen peroxide preparation by obtaining data collected by the humidity sensor.

[0037] Step S2, when the environmental state is determined to be a non-high humidity environment, the humidification device is turned on and the high voltage package output state is turned off; when the environmental state is determined to be a high humidity environment, the high voltage package is controlled to output a voltage according to a preset voltage value.

[0038] In an embodiment of the present invention, the high-voltage package refers to a module that generates a high-voltage output and is used to form an electric field to generate hydrogen peroxide. It is understandable that when the environmental state is determined to be a non-high-humidity environment, it means that the humidity of the current environment is already at a low level and there is no need to further increase the humidity. Therefore, turning off the output state of the high-voltage package can prevent dangerous situations that may occur during the preparation of hydrogen peroxide, while also avoiding waste of energy. In a high-humidity environment, the environmental state has reached the humidity level for preparing hydrogen peroxide, and the humidification device can be turned off to save energy costs. It is understandable that since the humidity of the environment is constantly changing, the humidity of the environment can be adjusted by controlling the opening and closing of the humidification device during subsequent cycle detection.

[0039] For example, in a humid environment such as a toilet or kitchen, the electrodes of the device are in a high humidity environment and there is no need to turn on the humidifier. There are excess positively charged particles in the air, forming an electric field. In order for the electric field to reach the energy required to produce H2O2, it is necessary to control the high-voltage package to output a voltage that can reach the critical condition for the production of H2O2.

[0040] Step S3, obtaining the first current signal of the current sensor collecting environmental space, and determining the air conductivity state as an adjustment state, an insufficient state or an excess state according to the first current signal; if the air conductivity is in an insufficient state, controlling the output voltage of the positive ion generator to increase according to a preset voltage value; if the air conductivity is in an adjustment state, maintaining the current output voltage state of the positive ion generator and maintaining the current state of the high-voltage package; if the air conductivity is in an excess state, turning off the positive ion generator and controlling the output voltage of the high-voltage package.

[0041] In the embodiment of the present invention, the first current signal is measured by the current sensor according to the ion concentration and conductivity in the air. The conductivity state of the air is determined according to the value of the first current signal. The state includes an adjustment state, an insufficient state or an excessive state.

[0042] Exemplarily, in the adjustment state, the air conductivity is in the ideal range for preparing hydrogen peroxide, and the positive ion generator will maintain a stable ion generation rate. For example, one thousand positive ions are released per second to ensure that the positive ion concentration in the space meets the standard to meet the needs of preparing hydrogen peroxide without increasing the voltage or re-adjusting the output. In the insufficient state, the air conductivity does not meet the conditions for preparing hydrogen peroxide, and the positive ions are generated more quickly by increasing the output voltage of the positive ion generator, for example, increasing it by 0.5kv each time. In the overflow state, to prevent excessive accumulation of positive ions, the positive ion generator is directly turned off, the output state of the high-voltage package is controlled, and the overflow positive ions are continuously consumed.

[0043] Step S4, obtain the second current signal of the current sensor collecting the ambient space, and determine whether the air conductivity state is qualified or unqualified according to the second current signal; if the air conductivity is qualified, maintain the current output voltage state of the positive ion generator, control the high-voltage package output voltage, and repeat step S4; if the air conductivity is unqualified, maintain the current output voltage state of the positive ion generator, turn off the high-voltage package output voltage, and enter step S3; repeat the above S1 to S4 operations until the power is turned off or the machine reports an error and the power supply stops.

[0044] In the embodiment of the present invention, the second current signal is measured by the current sensor according to the ion concentration and conductivity in the air. It can be understood that the first current signal is detected before adjustment, and the second current signal is detected after adjustment. The purpose of the second current signal detection is to check whether the actual change of air conductivity reaches the ideal range after adjusting the positive ion generator and the high-voltage package, so as to facilitate subsequent adjustment operations.

[0045] Exemplarily, when the air conductivity is determined to be in a qualified state, the positive ion generator will continue to work and generate positive ions, while the high-voltage package output voltage remains stable to ensure the positive ion concentration in the space. When the air conductivity is determined to be in an unqualified state, the positive ion generator still works, but since the high-voltage package no longer outputs voltage and no longer consumes positive ions in the space, the amount of positive ions generated increases, and it is necessary to enter the step in step S3 again to adjust the positive ion generator and control the high-voltage package. Thereby, real-time control adjustment is achieved, thereby improving the work efficiency of preparing hydrogen peroxide and the performance of producing hydrogen peroxide.

[0046] The embodiment of the present invention determines the current environmental state of hydrogen peroxide preparation by acquiring data collected by the humidity sensor, controls the state of the humidifier, keeps the humidifier in the open state in a high humidity environment, and controls the output voltage of the high-voltage package according to a preset voltage value to maintain an appropriate humidity level. The state of air conductivity is determined by first determining whether the air conductivity is insufficient, adjusted, or excessive, and taking corresponding control measures according to the judgment result, and then determining whether the air conductivity is qualified or unqualified. After the result is determined, a cyclic adjustment is performed, and the operation is repeated continuously to achieve precise control of humidity and air conductivity, and ensure that the air conductivity meets the requirements for preparing hydrogen peroxide in a high humidity environment, thereby effectively improving the production efficiency of hydrogen peroxide.

[0047] In this embodiment, a method for controlling the preparation conditions of hydrogen peroxide is also provided, which can be used in the above-mentioned computer device. Figure 2 : is a flow chart of a method for controlling the preparation conditions of hydrogen peroxide according to an embodiment of the present invention. Figure 2 As shown, the following steps are included:

[0048] Step S1, determining the current environmental state for preparing hydrogen peroxide by acquiring data collected by a humidity sensor.

[0049] Specifically, the above step S1 specifically includes:

[0050] Step S101, collecting the humidity signal of the environment space through the humidity sensor to obtain the actual humidity value of the environment.

[0051] Exemplarily, a capacitive humidity sensor, a resistive humidity sensor or a surface acoustic wave humidity sensor is used to collect the humidity signal of the ambient space, and the raw humidity data is read from the humidity sensor using a corresponding method according to the specifications and documentation of the sensor, and the raw data is converted into an actual humidity value according to the characteristics and calibration parameters of the sensor.

[0052] Step S102: If the actual humidity value is greater than the preset humidity threshold, it is determined to be a high humidity environment.

[0053] Exemplarily, H0 is set as the preset humidity threshold, H0 is set to 70%, if the actual humidity value read by the sensor is 75%, it is higher than the preset humidity threshold, and the current environmental state is determined to be a high humidity environment, so as to facilitate subsequent adjustment operations.

[0054] Step S103: if the actual humidity value is less than or equal to the preset humidity threshold, it is determined to be a non-high humidity environment.

[0055] Exemplarily, H0 is set as the preset humidity threshold, H0 is set to 70%. If the actual humidity value read by the sensor is 65%, it is lower than the preset humidity threshold, and the current environmental state is determined to be a non-high humidity environment. The humidity of the environment needs to be further optimized to meet the conditions for preparing hydrogen peroxide.

[0056] It should be noted that there is no chronological order between the above steps S102 and 103 , which are only illustrative in the pictures.

[0057] Step S2: When the environment is determined to be a non-high humidity environment, the humidification device is turned on and the high voltage package output state is turned off; when the environment is determined to be a high humidity environment, the high voltage package is controlled to output voltage according to a preset voltage value. Figure 1 Step S2 of the illustrated embodiment will not be described in detail here.

[0058] Step S3, obtain the first current signal of the current sensor collecting environment space, and determine whether the air conductivity state is an adjustment state, an insufficient state or an overflow state according to the first current signal; if the air conductivity is an insufficient state, control the positive ion generator output voltage to increase according to a preset voltage value; if the air conductivity is an adjustment state, maintain the current output voltage state of the positive ion generator and the current state of the high-voltage package; if the air conductivity is an overflow state, turn off the positive ion generator and control the output voltage of the high-voltage package. For details, please refer to Figure 1 Step S3 of the illustrated embodiment will not be described in detail here.

[0059] Step S4 obtains the second current signal of the current sensor collecting the ambient space, and determines whether the air conductivity state is qualified or unqualified according to the second current signal; if the air conductivity is qualified, the current output voltage state of the positive ion generator is maintained, the high-voltage package output voltage is controlled, and step S4 is repeated; if the air conductivity is unqualified, the current output voltage state of the positive ion generator is maintained, the high-voltage package output voltage is turned off, and step S3 is entered; the above S1 to S4 operations are repeated until the power is turned off or the machine reports an error and the power supply stops. For details, please refer to Figure 1 Step S4 of the illustrated embodiment will not be described in detail here.

[0060] This embodiment collects the humidity signal of the ambient space and compares it with a preset humidity threshold, so that the change of the ambient humidity can be sensed in time, thereby helping to more accurately determine whether the current space is in a high humidity environment, and helping to make adjustments as needed to maintain stable humidity conditions for hydrogen peroxide preparation.

[0061] In this embodiment, a method for controlling the preparation conditions of hydrogen peroxide is also provided, which can be used in the above-mentioned computer device. Figure 3 : is a flow chart of a method for controlling the preparation conditions of hydrogen peroxide according to an embodiment of the present invention. Figure 3 As shown, the following steps are included:

[0062] Step S1, determine the current environmental state of preparing hydrogen peroxide by obtaining data collected by the humidity sensor. Figure 1 Step S2 of the illustrated embodiment will not be described in detail here.

[0063] Step S2: When the environment is determined to be a non-high humidity environment, the humidification device is turned on and the high voltage package output state is turned off; when the environment is determined to be a high humidity environment, the high voltage package is controlled to output voltage according to a preset voltage value. Figure 1 Step S2 of the illustrated embodiment will not be described in detail here.

[0064] Step S3, obtaining the first current signal of the current sensor collecting environmental space, and determining the air conductivity state as an adjustment state, an insufficient state or an excess state according to the first current signal; if the air conductivity is in an insufficient state, controlling the output voltage of the positive ion generator to increase according to a preset voltage value; if the air conductivity is in an adjustment state, maintaining the current output voltage state of the positive ion generator and maintaining the current state of the high-voltage package; if the air conductivity is in an excess state, turning off the positive ion generator and controlling the output voltage of the high-voltage package.

[0065] Specifically, the above step S3 includes:

[0066] Step S301, converting the current signal into the actual current value i1.

[0067] It should be noted that the signal is obtained by measuring the current in the current loop, and the analog current signal is converted into a digital form for digital processing to obtain the actual value i1 of the current.

[0068] Exemplarily, the current signal collected by the current sensor is 0.5V. After analog-to-digital conversion, the converted digital signal is 350. After the digital signal processing step, the actual current value obtained is 10mA. Therefore, the conversion of the current signal to the actual current value i1 is 10mA. It can be understood that since the spatial state is constantly changing, i1 also changes continuously, and current acquisition needs to be performed within a preset time period.

[0069] Step S302, if the actual current value i1 is less than or equal to 0.75i0, it is determined that the air conductivity is in an insufficient state.

[0070] It should be noted that i0 refers to the current value collected when the output voltage of the high-voltage package and the distance between the high-voltage electrodes reach the preset critical condition to be broken down. It can be understood that when a voltage is applied between the high-voltage package and the high-voltage electrodes, when the voltage and the electrode distance reach a certain preset condition, an electric breakdown phenomenon will occur, that is, the current will flow through the air gap. In this case, the current value measured and collected by devices such as current sensors is i0, that is, the current standard value.

[0071] Exemplarily, assume i0 = 10mA. When the actual current value i1 is 7mA, which is less than 0.75i0, that is, i1 <= 0.75 * 10mA = 7.5mA, it is determined that the air conductivity is in an insufficient state. The insufficient state means that at the given output voltage of the high-voltage package and the distance between the high-voltage electrodes, the current cannot reach the preset critical condition, and the air cannot effectively conduct the current.

[0072] Step S303, if the actual current value i1 is greater than 0.75i0 and less than or equal to 1.25i0, it is determined that the air conductivity is in an adjustment state

[0073] Exemplarily, assume i0 = 10mA. When the actual current value i1 is 10mA, which is greater than 0.75i0 and less than or equal to 1.25i0, that is, 0.75 * 10mA < i1 <= 1.25 * 10mA, it is determined that the air conductivity is in an adjustment state. The adjustment state means that at the given output voltage of the high-voltage package and the distance between the high-voltage electrodes, the current is close to or slightly higher than the preset critical condition, and the air conductivity needs to be finely adjusted to reach a more ideal state for preparing hydrogen peroxide.

[0074] Step S304, if the actual current value i1 is greater than 1.25i0, it is determined that the air conductivity is in an excessive state.

[0075] For example, assuming i0=10mA, when the actual current value i1 is 15mA, which is greater than 1.25i0, that is, i1>1.25*10mA=12.5mA, it is determined that the air conductivity is in an overfill state. The overfill state means that under a given high-voltage package output voltage and high-voltage electrode spacing, the current exceeds the preset critical condition, the air conductivity is too high, and the positive ion concentration in the air needs to be reduced.

[0076] It should be noted that there is no order of precedence among the above steps S302 , S303 and S304 , which are only illustrative in the pictures.

[0077] Step S305, if the air conductivity is in an insufficient state, the output voltage of the positive ion generator is controlled to increase according to the preset voltage value; if the air conductivity is in an adjustment state, the current output voltage state of the positive ion generator is maintained, and the current state of the high-voltage package is maintained; if the air conductivity is in an excess state, the positive ion generator is turned off and the output voltage of the high-voltage package is controlled.

[0078] Step S4, obtain the second current signal of the current sensor collecting the ambient space, and determine whether the air conductivity state is qualified or unqualified according to the second current signal; if the air conductivity is qualified, maintain the current output voltage state of the positive ion generator, control the high-voltage package output voltage, and repeat step S4; if the air conductivity is unqualified, maintain the current output voltage state of the positive ion generator, turn off the high-voltage package output voltage, and enter step S3; repeat the above S1 to S4 operations until the power is turned off or the machine reports an error and the power supply stops.

[0079] Specifically, the above step S4, determining the air conductivity state according to the second current signal, includes:

[0080] Step S401, converting the current signal into the actual current value i2.

[0081] It should be noted that the method for obtaining the actual current value i2 is the same as the method for obtaining i1 in step S301 , and will not be described in detail herein.

[0082] Step S402: If the actual current value i2 is greater than the standard current value i0, the air conductivity is determined to be in a qualified state.

[0083] For example, assuming i0=10mA, when the actual current value i2 is 15mA, which is greater than i0, that is, i2>10mA, the air conductivity is determined to be in a qualified state. The qualified state means that when preparing the hydrogen peroxide solution, the current flow in the air can meet the preset requirements, ensuring the normal progress of the reaction. The air conductivity in the qualified state can ensure the quality and stability of the hydrogen peroxide solution, so there is no need to adjust the state of the high-voltage package and the positive ion generator in the subsequent steps. It only needs to maintain the current state to make the air conductivity within the ideal range.

[0084] Step S403: If the actual current value i2 is less than or equal to the standard current value i0, the air conductivity is determined to be in an unqualified state.

[0085] For example, assuming i0=10mA, when the actual current value i2 is 7mA, which is less than i0, that is, i2<=10mA, the air conductivity is determined to be in an unqualified state. The unqualified state means that when preparing the hydrogen peroxide solution, the current flow in the air fails to meet the preset requirements, which may affect the reaction.

[0086] It should be noted that there is no chronological order between the above steps S402 and S403, which are only illustrative in the picture.

[0087] Step S404, if the air conductivity is in a qualified state, the current output voltage state of the positive ion generator is maintained, the high-voltage package output voltage is controlled, and step S4 is repeated; if the air conductivity is unqualified, the current output voltage state of the positive ion generator is maintained, the high-voltage package output voltage is turned off, and step S3 is entered; repeat the above S1 to S4 operations until the power is turned off or the machine reports an error and the power supply stops.

[0088] This embodiment accurately determines the state of air conductivity by converting the current signal into an actual current value i1 and comparing it with a preset current value i0. The air conductivity is determined to be insufficient, adjusted, or excessive, thereby providing a more accurate basis for judgment and facilitating more precise adjustment of the state of the positive ion generator or the high-voltage package during subsequent cycles. By converting the current signal into an actual current value i2 and comparing it with the preset current standard value i0, the qualified and unqualified states of the air conductivity can be accurately determined, the two states can be directly divided, the qualification of the air conductivity can be quickly determined, and the next control operation can be intuitively determined to maintain the current state or continue the cycle adjustment.

[0089] In this embodiment, a method for controlling the preparation conditions of hydrogen peroxide is also provided, which can be used in the above-mentioned computer device, comprising the following steps:

[0090] Step S1, determining the current environmental state for preparing hydrogen peroxide by acquiring data collected by a humidity sensor.

[0091] Furthermore, after the above step S1 determines the current environmental state for preparing hydrogen peroxide by acquiring data collected by the humidity sensor, it also includes: according to a preset collection time period, repeating the above operation of determining the current environmental state by acquiring data collected by the humidity sensor, if the environmental state is determined to be a non-high humidity environment for a preset number of consecutive times, the machine reports an error and stops powering on.

[0092] Exemplarily, the number of consecutive preset times is first determined, for example, set to 3 times, and the humidity sensor is used to regularly collect humidity data of the current environment, and the data collected each time is recorded according to the collection time period, for example, once every 10 seconds, and stored in a counter. When the environmental state is determined to be a non-high humidity environment, the counter is increased by 1, and when the environmental state is determined to be a high humidity environment, the counter is reset to 0. Avoid wasting power resources by continuing to run the machine that may cause problems when a non-high humidity environment appears continuously.

[0093] Step S2: When the environment is determined to be a non-high humidity environment, the humidification device is turned on and the high voltage package output state is turned off; when the environment is determined to be a high humidity environment, the high voltage package is controlled to output voltage according to a preset voltage value. Figure 1 Step S2 of the illustrated embodiment will not be described in detail here.

[0094] Step S3, obtain the first current signal of the current sensor collecting environment space, and determine whether the air conductivity state is an adjustment state, an insufficient state or an overflow state according to the first current signal; if the air conductivity is an insufficient state, control the positive ion generator output voltage to increase according to a preset voltage value; if the air conductivity is an adjustment state, maintain the current output voltage state of the positive ion generator and the current state of the high-voltage package; if the air conductivity is an overflow state, turn off the positive ion generator and control the output voltage of the high-voltage package. For details, please refer to Figure 1 Step S3 of the illustrated embodiment will not be described in detail here.

[0095] Step S4 obtains the second current signal of the current sensor collecting the ambient space, and determines whether the air conductivity state is qualified or unqualified according to the second current signal; if the air conductivity is qualified, the current output voltage state of the positive ion generator is maintained, the high-voltage package output voltage is controlled, and step S4 is repeated; if the air conductivity is unqualified, the current output voltage state of the positive ion generator is maintained, the high-voltage package output voltage is turned off, and step S3 is entered; the above S1 to S4 operations are repeated until the power is turned off or the machine reports an error and the power supply stops. For details, please refer to Figure 1 Step S4 of the illustrated embodiment will not be described in detail here.

[0096] Furthermore, after determining the state of air conductivity according to the current signal in the above step S3 or S4, it also includes: when the air conductivity is determined to be insufficient for a preset number of consecutive times, the machine reports an error and stops powering on.

[0097] Exemplarily, the number of consecutive preset times is first determined, for example, set to 5 times, and the current sensor is used to regularly collect the current data of the current environment, and the data collected each time is recorded according to the collection time period, for example, once every 10 seconds, and stored in the counter. When the environmental state is determined to be insufficient or unqualified, the counter is increased by 1, and the counter is reset to 0 in the adjustment state, interference state, and qualified state. When the preset number is reached or exceeded, an error operation is performed and the power supply is stopped.

[0098] It is understandable that it is determined here that there is a problem with the positive ion generator, which is unable to create an environment with a higher air conductivity, affecting the working efficiency of the high-voltage electrostatic field, and thus making it impossible to create an environment with an excessive concentration of positively charged particles to prepare hydrogen peroxide.

[0099] This embodiment stops power supply when the air conductivity is determined to be insufficient for a preset number of times, that is, stops power supply to the entire system and reports an error when the air conductivity is continuously determined to be insufficient, thereby ensuring fault detection and device protection, and timely discovering and solving problems with the positive ion generator. By stopping power supply when the environmental state is determined to be a non-high humidity environment for a preset number of times, that is, stops power supply to the entire system and reports an error when the environmental state is continuously determined to be a non-high humidity environment, thereby ensuring fault detection and device protection, timely discovering and solving problems with the humidification device, ensuring system operation and saving resources, and thereby ensuring that hydrogen peroxide can be prepared under high humidity conditions.
