[0072] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.
[0073] Example 1
[0074] This embodiment provides a monitoring device for an electric purification component, wherein the electric purification component includes a plurality of emitters and receivers arranged at intervals along a first direction. Figure 1 The monitoring device includes: a controller 1 and a brightness acquisition component 2.
[0075] The controller 1 is electrically connected to the brightness collection component 2 .
[0076] The brightness collection component 2 is used to generate a plurality of currents according to the brightness of the emitter in different directions, and send the current values of the plurality of currents to the controller 1 .
[0077] The controller 1 is used to obtain a reference current value and a noise current value, wherein the reference current value is positively correlated with the initial current value corresponding to the initial time point, and the noise current value is determined by the current value corresponding to when the emitter is in a non-discharging state.
[0078] The controller 1 is further configured to generate a discharge state monitoring result according to the current value, the reference current value, and the noise current value, wherein the discharge state monitoring result is used to indicate whether the emitter is in a normal working state.
[0079] in, Figure 2AThis diagram shows the structure of an example electrical purification component B0. The emitter B1 can be a tungsten wire with a diameter no greater than 0.5 mm, and the receiver B2 is a metal plate. The emitter B1 and receiver B2 are spaced apart along a first direction. Due to the structure of electrical purification component B0, emitter B1 is more susceptible to failure or damage than receiver B2 after discharge.
[0080] Reference Figure 2B The light-collecting surface of brightness collection component 2 faces electrical purification component B0. When electrical purification component B0 is in the discharge state, air ionization occurs, increasing the brightness of the air around emitter B1 and generating a corona. Brightness collection component 2 generates a current value based on the collected brightness and sends it to controller 1.
[0081] The initial time point refers to the first use of the electric purification component to be monitored (i.e., the first time it is in a discharge state). At the initial time point, the initial current value of the discharge state of the electric purification component when it is first used is used as one of the reference bases for the normal state.
[0082] The method for obtaining the initial current value is similar to the method for obtaining the current value, and will not be repeated here.
[0083] Due to the electrical properties of electronic components, even if the electrical purification component is not discharging (i.e., in a non-discharging state) and is in a darkroom environment, the brightness collection component will still generate a non-zero current, i.e., the noise current in a darkroom environment. The noise current in an environment with background light is greater than the noise current in a darkroom environment. Therefore, in order to reflect the actual brightness, it is necessary to remove the noise current in the same environment from the current value generated by the collection. The noise current is also one of the reference bases for the normal state of the electrical purification component.
[0084] If an electrical purification component is replaced, the reference current value and noise current value of the replaced component need to be obtained as a reference for the normal state of the electrical purification component. If part of the emitter of the electrical purification component is replaced, the reference current value and noise current value corresponding to the replaced emitter need to be obtained as a reference for the normal state of the emitter.
[0085] In this embodiment, the brightness of the discharge state of the electric purification component is collected by the brightness collection component, and the discharge state monitoring result of the electric purification component is generated according to the brightness, the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, thereby realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault location prompt, thereby improving safety, enhancing user experience, and low cost.
[0086] During specific implementation, the brightness acquisition component 2 includes: a plurality of photoreceptor arrays 21 .
[0087] The photoreceptor array 21 includes a plurality of first photoreceptors 211 and a plurality of second photoreceptors 212 .
[0088] Each photoreceptor array 21 is electrically connected to the controller 1 . The photoreceptor arrays 21 correspond to the emitters one by one, and the light-collecting surface of each photoreceptor array 21 faces a corresponding emitter.
[0089] Each first photoreceptor 211 is configured to generate a first current according to the collected brightness in a first direction.
[0090] Each second photoreceptor 212 is configured to generate a second current according to the collected brightness in a second direction, wherein the second direction is parallel to the axis of the emitter.
[0091] The photoreceptor array 21 is configured to send the current value of the first current and the current value of the second current to the controller 1 .
[0092] The reference current values include a first reference current value corresponding to the first current and a second reference current value corresponding to the second current.
[0093] The controller 1 is specifically configured to subtract corresponding noise current values from the current value of the first current and the current value of the second current respectively to obtain a first current difference value and a second current difference value.
[0094] The controller 1 is further specifically configured to generate a discharge state monitoring result according to the first current difference, the second current difference, the first reference current value, and the second reference current value.
[0095] Among them, reference Figure 2C The first photoreceptors 211 and the second photoreceptors 212 are arranged at intervals in the first direction. The number and arrangement of the first photoreceptors 211 and the second photoreceptors 212 can be set according to actual needs.
[0096] For each photoreceptor (first or second), the current value it generates in real time corresponds to its reference current value and noise current value. The reference current value and noise current value of the photoreceptor are related to the arrangement position of the photoreceptor relative to the emitter and the electrical performance of the circuit.
[0097] In this embodiment, the brightness of the discharge state of the electric purification component is collected through a photoreceptor array, and the discharge state monitoring result of the electric purification component is generated according to the brightness, the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, thereby realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault location prompt, thereby improving safety, enhancing user experience, and low cost.
[0098] During specific implementation, the controller 1 is further configured to, for each emitter, when the second current difference is less than the second reference current value, monitor the discharge state to indicate that the corresponding emitter is in a normal working state.
[0099] The controller 1 is further specifically configured to, for each emitter, when the second current difference is not less than the second reference current value and the first current differences are less than the first reference current value, monitor the discharge state to indicate that the corresponding emitter is in a locally ionized enhanced state.
[0100] The controller 1 is further specifically configured to, for each emitter, when the second current difference is not less than the second reference current value and the first current difference is not less than the first reference current value, monitor the discharge state to indicate that the corresponding emitter is in an overall ionization-enhanced state.
[0101] A higher brightness indicates a higher degree of ionization. Because the emitter has an elongated shape, the brightness in the second direction reflects the emitter's overall degree of ionization, allowing for determination of whether the emitter is operating normally. When the corresponding emitter is not operating normally, the first current difference can be used to determine the degree of abnormality in the emitter. The degree of abnormality in a state of increased overall ionization is higher than that in a state of increased local ionization.
[0102] When the emitter is in a state of locally increased ionization, the electrical purification component needs to be repaired, such as removing burrs on the corresponding emitter or replacing the corresponding emitter. When the emitter is in a state of overall increased ionization, it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component increases, and air ionization increases, which may lead to excessive ozone and emitter breakage, posing a risk of electric shock.
[0103] Multiple reference current values may be set according to actual needs to classify the abnormality into multiple abnormality degrees.
[0104] A current difference threshold can be set, positively correlated with a first reference current value. When the corresponding emitter is not operating normally, the coordinates of the first photoreceptor whose first current difference exceeds the threshold are output, providing a fault location indicator. By mapping the coordinates of the first photoreceptor to the plane containing the emitter and receiver, the abnormal area on that plane can be determined.
[0105] In this embodiment, the second current difference is used to determine whether the emitter is in a normal working state. When the emitter is not in a normal working state, the first current difference is used to determine the abnormality degree and abnormal area of the emitter, and then corresponding processing is performed according to the risk status, thereby realizing real-time and effective monitoring of the electrical purification components. When the electrical purification components are abnormal, component failure warnings and fault location prompts can be provided, thereby improving safety, enhancing user experience, and low cost.
[0106] In a specific implementation, in each photoreceptor array 21 , the first photoreceptors 211 with the same coordinate in the second direction belong to the same first photoreceptor group, and the second photoreceptors 212 with the same coordinate in the first direction belong to the same second photoreceptor group.
[0107] The first photoreceptors 211 in the same first photoreceptor group are electrically interconnected, and the second photoreceptors 212 in the same second photoreceptor group are electrically interconnected.
[0108] in, Figure 2C , the first photoreceptors 211 in the dot-dash line frame belong to the same first photoreceptor group, and the second photoreceptors 212 in the dotted line frame belong to the same second photoreceptor group.
[0109] The sum of the current values of the first photoreceptors in the same first photoreceptor group is the current value generated by the first photoreceptor group, and the sum of the current values of the second photoreceptors in the same second photoreceptor group is the current value generated by the second photoreceptor group. That is, each first photoreceptor group generates only one current value, and each second photoreceptor group also generates only one current value. The first photoreceptor group can be considered as a larger first photoreceptor, and the second photoreceptor group can be considered as a larger second photoreceptor.
[0110] In this case, the number of current values generated by the first and second photoreceptor groups is reduced. Because the reference current and noise current values are determined by the current values of the brightness acquisition component at different time points, the number of corresponding reference and noise current values is also reduced. This reduces the amount of data processing and calculation required for the current values, speeding up the generation of discharge status monitoring results. The method for generating discharge status monitoring results using the first and second photoreceptor groups is similar to the method used when the photoreceptors are not electrically interconnected, and will not be further described here.
[0111] Especially for the filamentary emitter, since the second current with the same coordinate in the first direction does not change much, a second photoreceptor group is used, and each second photoreceptor group generates a second current, which simplifies data processing and calculation, and can meet the need of judging whether the electrical purification component is in normal working condition; a first photoreceptor group is used, and each first photoreceptor group generates a first current, which simplifies data processing and calculation, and can meet the need of fault location when the electrical purification component is not in normal working condition.
[0112] In order to ensure the amount of effective data information, reduce the amount of data processing and calculation, and lower the cost of the device, the number of the first photoreceptor groups is the same as the number of the second photoreceptor groups, and both are integers not greater than 5.
[0113] In a specific implementation, the controller 1 is further configured to obtain a current value corresponding to when the emitter is in a non-discharging state and use the current value in the non-discharging state as the noise current value.
[0114] The controller 1 is further configured to obtain an initial current value, wherein the initial current value includes a first initial current value corresponding to the first current and a second initial current value corresponding to the second current.
[0115] The controller 1 is further configured to calculate a first reference current value and a second reference current value. The first reference current value is the product of a difference between a first initial current value and a corresponding noise current value and a preset first correction coefficient, and the second reference current value is the product of a difference between a second initial current value and a corresponding noise current value and a preset second correction coefficient.
[0116] The second reference current value is increased by the second correction coefficient, that is, the allowable second current difference range is increased to accommodate the influence of factors such as voltage fluctuation of the electric purification component. The second correction coefficient can be set according to actual needs.
[0117] The first correction coefficient can be set according to actual needs to reasonably distinguish abnormal states of the emitter.
[0118] In this embodiment, a specific implementation method for obtaining a reference current value and a noise current value is provided.
[0119] During specific implementation, the monitoring device further includes: a cavity 3 .
[0120] The cavity 3 is used to accommodate the electric purification components so that the electric purification components are placed in a darkroom environment.
[0121] Among them, reference Figure 2B The bracket B3 of the electrical purification component B0 can be mounted on the cavity 3, placing the electrical purification component B0 inside the cavity 3. The opaque cavity 3 provides a darkroom environment for monitoring the electrical purification component B0. The darkroom environment provided by the cavity makes the brightness of the emitter stand out compared to the surrounding environment, making it easy to identify, while also reducing the noise current value.
[0122] In this embodiment, due to the presence of the cavity, the electrical purification component is placed in a darkroom environment, making the brightness of the emitter easy to identify, while also reducing the noise current value. The discharge status monitoring result of the electrical purification component is generated based on the brightness, and the risk status of the emitter is determined. Then, corresponding processing is performed according to the risk status, thereby realizing real-time and effective monitoring of the electrical purification component. When the electrical purification component is abnormal, it can provide component failure warning and fault location prompts, thereby improving safety, enhancing user experience, and low cost.
[0123] During specific implementation, a detection window 4 is provided on the cavity 3 .
[0124] The brightness acquisition component 2 is arranged outside the cavity 3, and the brightness acquisition component 2 acquires brightness through the detection window 4.
[0125] Among them, referring to Figure 2B , a detection window 4 is provided on the cavity 3, the brightness acquisition component 2 is arranged outside the cavity 3, the brightness acquisition component 2 acquires brightness through the detection window 4, and the dotted line in the figure represents the brightness acquisition range of the brightness acquisition component 2. The detection window 4 is provided at the bottom of the cavity 3, and the included angle between the bottom surface of the cavity 3 and the horizontal plane is a preset angle. This angle can be set according to actual needs so that the brightness acquisition range of the brightness acquisition component can cover all emitters and receivers.
[0126] The following is an example of implementing the monitoring method of the electro-purification component.
[0127] Taking Figure 2A and 2B shown in the electro-purification component and the layout of monitoring the electro-purification component as an example, several currents can be generated by the brightness acquisition component collecting the brightness of the emitter in different directions in the electro-purification component, and the current value of this current reflects the discharge state of the electro-purification component.
[0128] Example 1
[0129] In this example, the photosensors are not electrically interconnected with each other, that is, the first photosensor group and the second photosensor group are not adopted.
[0130] When the electro-purification component is started for the first time, according to the brightness of the electro-purification component in the discharge state, an array P1[m] of the first initial current values of the first photosensor and an array P2[m] of the second initial current values of the second photosensor are obtained. P1[m] includes the first initial current value I of the first photosensor ,
[0132] , P2[m] includes the second initial current value I of the second photosensor [[ID=二十九]] yik , where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, j represents the serial number of the first photosensor, k represents the serial number of the second photosensor, m represents M - 1 and satisfies the integer of i < m, and M represents the number of emitters of the electro-purification component.
[0131] When the emitter i is in the non-discharge state, the current value of each photosensor is used as the noise current value Z of the photosensor j i . Among them, the current value of the first photosensor j is used as the noise current value Z of the first photosensor j ij , and the current value of the second photosensor k is used as the noise current value Z of the second photosensor k ik .
[0132] Set the first correction coefficient to 2 and the second correction coefficient to 5.
[0133] The first initial current value I xij minus the corresponding noise current value (Z ij ) to obtain the difference ΔI xij , that is:
[0134] ΔI xij = I xij - Z ij .
[0135] The second initial current value I yik minus the corresponding noise current value (Z ik ) to obtain the difference ΔI yik , that is:
[0136] ΔI yik = I yik - Z ik .
[0137] Then, the first reference current value R of the first photosensor j[[ID=xij Subtract the noise current value (Z ij ) obtains the first current difference △T of the first photoreceptor j xij ,Right now:
[0142] △T xij =T xij -Z ij .
[0143] The second current value T of the second photoreceptor k yik Subtract the noise current value (Z ik ) obtains the second current difference ΔT of the second photoreceptor k yik ,Right now:
[0144] △T yik =T yik -Z ik .
[0145] Analyze the discharge state of each emitter:
[0146] When the second current difference △T of emitter i yik are both less than the second reference current value R xik When △T yik <5*△I yik The electric purification component is in a normal working state. The second reference current value is increased by the second correction coefficient to accommodate the influence of factors such as voltage fluctuation of the electric purification component.
[0147] There is a second current difference △T at the emitter i yik Not less than the second reference current value R xik And the first current difference △T xij are both less than the first reference current value R xij When △T yik ≥5*△I yik And △T xij <2*△I xij When the discharge state monitoring results indicate that emitter i is in a state of localized ionization aggravation, the electrical purification component experiences localized ionization aggravation and outputs abnormal areas. This requires repair of the electrical purification component, such as removing burrs from the corresponding emitter or replacing the corresponding emitter.
[0148] There is a second current difference △T at the emitter i yik Not less than the second reference current value R xik And the first current difference △T xij Not less than the first reference current value R xij When △T yik ≥5*△I yik And △Txij ≥2*△I xij When it is ≥2*△I, the discharge state monitoring result indicates that the emitter i is in a state of increased overall ionization. It is recommended to replace the electro-purification component. There is a possibility that the curvature of some emitters in the electro-purification component increases, air ionization intensifies, ozone exceeds the standard, and the emitter breaks, posing an electric shock risk.
[0149] Example 2
[0150] In this example, the first photosensor group and the second photosensor group are adopted. The first photosensor group can be regarded as a relatively large first photosensor, and the second photosensor group can be regarded as a relatively large second photosensor. The method for generating the discharge state monitoring result in this example is similar to the method in Example 1.
[0151] When the electro-purification component is started for the first time, according to the brightness of the electro-purification component in the discharge state, obtain the array P′1[m] of the first initial current values of the first photosensor group and the array P′2[m] of the second initial current values of the second photosensor group. P′1[m] includes the first initial current value I′ of the first photosensor group xie , and P′2[m] includes the second initial current value I′ of the second photosensor group yif , where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, e represents the serial number of the first photosensor group, f represents the serial number of the second photosensor group, m represents an integer of M - 1 and satisfies i < m, and M represents the number of emitters of the electro-purification component.
[0152] When the emitter i is in the non-discharge state, use the current value of each photosensor group as the noise current value Z′ of the photosensor group e i . Among them, use the current value of the first photosensor group e as the noise current value Z′ of the first photosensor group e ie , and use the current value of the second photosensor group f as the noise current value Z′ of the second photosensor group f if .
[0153] Set the first correction factor to 2 and the second correction factor to 5.
[0154] The first initial current value I′ xie Subtract the corresponding noise current value (Z′ ie ) to obtain the difference △I′ xie , that is:
[0155] △I′ xie =I′ xie -Z′ ie .
[0156] The second initial current value I′ yif Subtract the corresponding noise current value (Z′ if)The obtained difference ΔI′ yif , that is:
[0157] ΔI′ yif = I′ yif - Z′ if .
[0158] Then, the first reference current value R′ of the first photosensor group e xie and the second reference current value R′ of the second photosensor group f xif can be obtained, that is:
[0159] R′ xie = 2 * ΔI′ xie R′ xif = 5 * ΔI′ yif .
[0160] I′ xie , Z′ ie and ΔI′ xie can form an array P′11[m], I′ yif , Z′ if and ΔI′ yif can form an array P′21[m], and P′11[m] and P′21[m] can be stored as the reference current values of the system in independent data storage areas respectively.
[0161] When the electric purification component is working, the brightness acquisition component acquires the brightness of the electric purification component in the discharge state at a fixed frequency f, and obtains an array T′1[m] of the first current values of the first photosensor group e and an array T′2[m] of the second current values of the second photosensor group f according to the brightness. T′1[m] includes the first current value T′ of the first photosensor group e xie [[ID=…]] , T′2[m] includes the second current value T′ of the second photosensor group f yif , where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, e represents the serial number of the first photosensor group, f represents the serial number of the second photosensor group, m represents an integer of M - 1 and satisfies i < m, and M represents the number of emitters of the electric purification component.
[0162] The first current value T′ of the first photosensor group e xie subtracted from the corresponding noise current value (Z′ ie ) of the first photosensor group e obtains the first current difference ΔT′ of the first photosensor group e xie , that is:
[0163] ΔT′ xie = T′ xie - Z′ ie .
[0164] The second current value T′ of the second photoreceptor group f yif Subtract the noise current value (Z′) of the corresponding second photoreceptor group f if ) obtains the second current difference △T′ of the second photoreceptor group f yif ,Right now:
[0165] △T′ yif =T′ yif -Z′ if .
[0166] Analyze the discharge state of each emitter:
[0167] When the second current difference △T′ of emitter i yif are both less than the second reference current value R′ xif When △T′ yif <5*△I′ yif The electric purification component is in a normal working state. The second reference current value is increased by the second correction coefficient to accommodate the influence of factors such as voltage fluctuation of the electric purification component.
[0168] There is a second current difference △T' at the emitter i yif Not less than the second reference current value R' xif And the first current difference ΔT′ xie are both less than the first reference current value R′ xie When △T′ yif ≥5*△I′ yif And △T′ xie <2*△I′ xie When the discharge state monitoring results indicate that emitter i is in a state of localized ionization aggravation, the electrical purification component experiences localized ionization aggravation and outputs abnormal areas. This requires repair of the electrical purification component, such as removing burrs from the corresponding emitter or replacing the corresponding emitter.
[0169] There is a second current difference △T' at the emitter i yif Not less than the second reference current value R' xif And the first current difference ΔT′ xie Not less than the first reference current value R' xie When △T′ yif ≥5*△I′ yif And △T′ xie ≥2*△I′ xie When the discharge status monitoring results indicate that the emitter i is in a state of increased overall ionization, it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component has increased, and air ionization has intensified. There is a possibility of excessive ozone and emitter fracture, which may pose a risk of electric shock.
[0170] Example 2
[0171] This embodiment provides a monitoring method for an electric purification component, which is implemented using the monitoring device for the electric purification component in Example 1. The monitoring method is applied to the controller of the monitoring device. Figure 3 , monitoring methods include:
[0172] S11. Receive the current value generated by the brightness acquisition component.
[0173] S12. Obtain a reference current value and a noise current value, wherein the reference current value is positively correlated with the initial current value corresponding to the initial time point, and the noise current value is determined by the current value corresponding to when the emitter is in a non-discharging state.
[0174] S13: Generate a discharge state monitoring result according to the current value, the reference current value, and the noise current value, wherein the discharge state monitoring result is used to indicate whether the emitter is in a normal working state.
[0175] in, Figure 2A This diagram shows the structure of an example electrical purification component B0. The emitter B1 can be a tungsten wire with a diameter no greater than 0.5 mm, and the receiver B2 is a metal plate. The emitter B1 and receiver B2 are spaced apart along a first direction. Due to the structure of electrical purification component B0, emitter B1 is more susceptible to failure or damage than receiver B2 after discharge.
[0176] Reference Figure 2B The light-collecting surface of brightness collection component 2 faces electrical purification component B0. When electrical purification component B0 is in the discharge state, air ionization occurs, increasing the brightness of the air around emitter B1 and generating a corona. Brightness collection component 2 generates a current value based on the collected brightness and sends it to controller 1.
[0177] The initial time point refers to the first use of the electric purification component to be monitored (i.e., the first time it is in a discharge state). At the initial time point, the initial current value of the discharge state of the electric purification component when it is first used is used as one of the reference bases for the normal state.
[0178] The method for obtaining the initial current value is similar to the method for obtaining the current value, and will not be repeated here.
[0179] Due to the electrical properties of electronic components, even if the electrical purification component is not discharging (i.e., in a non-discharging state) and is in a darkroom environment, the brightness collection component will still generate a non-zero current, i.e., the noise current in a darkroom environment. The noise current in an environment with background light is greater than the noise current in a darkroom environment. Therefore, in order to reflect the actual brightness, it is necessary to remove the noise current in the same environment from the current value generated by the collection. The noise current is also one of the reference bases for the normal state of the electrical purification component.
[0180] If an electrical purification component is replaced, the reference current value and noise current value of the replaced component need to be obtained as a reference for the normal state of the electrical purification component. If part of the emitter of the electrical purification component is replaced, the reference current value and noise current value corresponding to the replaced emitter need to be obtained as a reference for the normal state of the emitter.
[0181] In this embodiment, the brightness of the discharge state of the electric purification component is collected by the brightness collection component, and the discharge state monitoring result of the electric purification component is generated according to the brightness, the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, thereby realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault location prompt, thereby improving safety, enhancing user experience, and low cost.
[0182] In a specific implementation, the reference current value includes a first reference current value corresponding to the first current and a second reference current value corresponding to the second current.
[0183] Reference Figure 4 , step S13 includes:
[0184] S131 . Subtract corresponding noise current values from the current value of the first current and the current value of the second current respectively to obtain a first current difference and a second current difference.
[0185] S132 : Generate a discharge state monitoring result according to the first current difference, the second current difference, the first reference current value, and the second reference current value.
[0186] Among them, reference Figure 2C The first photoreceptors 211 and the second photoreceptors 212 are arranged at intervals in the first direction. The number and arrangement of the first photoreceptors 211 and the second photoreceptors 212 can be set according to actual needs.
[0187] For each photoreceptor (first or second), the current value it generates in real time corresponds to its reference current value and noise current value. The reference current value and noise current value of the photoreceptor are related to the arrangement position of the photoreceptor relative to the emitter and the electrical performance of the circuit.
[0188] In this embodiment, the brightness of the discharge state of the electric purification component is collected through a photoreceptor array, and the discharge state monitoring result of the electric purification component is generated according to the brightness, the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, thereby realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault location prompt, thereby improving safety, enhancing user experience, and low cost.
[0189] In specific implementation, step S132 includes:
[0190] For each emitter, when the second current difference is less than the second reference current value, the discharge state monitoring result indicates that the corresponding emitter is in a normal working state.
[0191] For each emitter, when the second current difference is not less than the second reference current value and the first current differences are less than the first reference current value, the discharge state monitoring result indicates that the corresponding emitter is in a locally ionized enhanced state.
[0192] For each emitter, when the second current difference is not less than the second reference current value and the first current difference is not less than the first reference current value, the discharge state monitoring result indicates that the corresponding emitter is in an overall ionization-enhanced state.
[0193] A higher brightness indicates a higher degree of ionization. Because the emitter has an elongated shape, the brightness in the second direction reflects the emitter's overall degree of ionization, allowing for determination of whether the emitter is operating normally. When the corresponding emitter is not operating normally, the first current difference can be used to determine the degree of abnormality in the emitter. The degree of abnormality in a state of increased overall ionization is higher than that in a state of increased local ionization.
[0194] When the emitter is in a state of locally increased ionization, the electrical purification component needs to be repaired, such as removing burrs on the corresponding emitter or replacing the corresponding emitter. When the emitter is in a state of overall increased ionization, it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component increases, and air ionization increases, which may lead to excessive ozone and emitter breakage, posing a risk of electric shock.
[0195] Multiple reference current values may be set according to actual needs to classify the abnormality into multiple abnormality degrees.
[0196] A current difference threshold can be set, positively correlated with a first reference current value. When the corresponding emitter is not operating normally, the coordinates of the first photoreceptor whose first current difference exceeds the threshold are output, providing a fault location indicator. By mapping the coordinates of the first photoreceptor to the plane containing the emitter and receiver, the abnormal area on that plane can be determined.
[0197] In this embodiment, the second current difference is used to determine whether the emitter is in a normal working state. When the emitter is not in a normal working state, the first current difference is used to determine the abnormality degree and abnormal area of the emitter, and then corresponding processing is performed according to the risk status, thereby realizing real-time and effective monitoring of the electrical purification components. When the electrical purification components are abnormal, component failure warnings and fault location prompts can be provided, thereby improving safety, enhancing user experience, and low cost.
[0198] In one embodiment, when the first photoreceptors in the same first photoreceptor group are electrically interconnected and the second photoreceptors in the same second photoreceptor group are electrically interconnected, the sum of the current values of the first photoreceptors in the same first photoreceptor group is the current value generated by the first photoreceptor group, and the sum of the current values of the second photoreceptors in the same second photoreceptor group is the current value generated by the second photoreceptor group. That is, each first photoreceptor group generates only one current value, and each second photoreceptor group also generates only one current value. The first photoreceptor group can be considered as a larger first photoreceptor, and the second photoreceptor group can be considered as a larger second photoreceptor.
[0199] In this case, the number of current values generated by the first and second photoreceptor groups is reduced. Because the reference current and noise current values are determined by the current values of the brightness acquisition component at different time points, the number of corresponding reference and noise current values is also reduced. This reduces the amount of data processing and calculation required for the current values, speeding up the generation of discharge status monitoring results. The method for generating discharge status monitoring results using the first and second photoreceptor groups is similar to the method used when the photoreceptors are not electrically interconnected, and will not be further described here.
[0200] Especially for the filamentary emitter, since the second current with the same coordinate in the first direction does not change much, a second photoreceptor group is used, and each second photoreceptor group generates a second current, which simplifies data processing and calculation, and can meet the need of judging whether the electrical purification component is in normal working condition; a first photoreceptor group is used, and each first photoreceptor group generates a first current, which simplifies data processing and calculation, and can meet the need of fault location when the electrical purification component is not in normal working condition.
[0201] In order to ensure the amount of effective data information, reduce the amount of data processing and calculation, and lower the cost of the device, the number of the first photoreceptor groups is the same as the number of the second photoreceptor groups, and both are integers not greater than 5.
[0202] When implementing it, refer to Figure 5 In step S12, “obtaining the noise current value” includes:
[0203] S121 , obtaining a current value corresponding to when the emitter is in a non-discharge state and using the current value in the non-discharge state as a noise current value.
[0204] The step of "obtaining a reference current value" in step S12 includes:
[0205] S122: Acquire initial current values, wherein the initial current values include a first initial current value corresponding to the first current and a second initial current value corresponding to the second current.
[0206] S123. Calculate the first reference current value and the second reference current value. Among them, the first reference current value is the product of the difference obtained by subtracting the corresponding noise current value from the first initial current value and a preset first correction coefficient, and the second reference current value is the product of the difference obtained by subtracting the corresponding noise current value from the second initial current value and a preset second correction coefficient.
[0207] Among them, the order of steps S121 and S122 can be interchanged.
[0208] Adjust the second reference current value by the second correction coefficient, that is, adjust the allowable range of the second current difference to accommodate the influence of factors such as voltage fluctuations of the electric purification component. The second correction coefficient can be set according to actual needs.
[0209] The first correction coefficient can be set according to actual needs to reasonably distinguish the abnormal state of the emitter.
[0210] In this embodiment, a specific implementation manner for obtaining the reference current value and the noise current value is provided.
[0211] The following is an example of implementing the monitoring method of the electric purification component.
[0212] Taking Figure 2A and 2B the shown electric purification component and the layout of monitoring the electric purification component as an example, several currents can be generated by the brightness acquisition component collecting the brightness of the emitter in different directions in the electric purification component, and the current value of this current reflects the discharge state of the electric purification component.
[0213] Example 1
[0214] In this example, the photosensors are not electrically interconnected with each other, that is, the first photosensor group and the second photosensor group are not adopted.
[0215] When the electric purification component is started for the first time, according to the brightness of the electric purification component in the discharge state, obtain the array P1[m] of the first initial current values of the first photosensor and the array P2[m] of the second initial current values of the second photosensor. P1[m] includes the first initial current value I xij of the first photosensor, and P2[m] includes the second initial current value I yik of the second photosensor. Among them, i represents the serial number of the emitter, x represents the first direction, y represents the second direction, j represents the serial number of the first photosensor, k represents the serial number of the second photosensor, m represents M - 1 and satisfies the integer of i < m, and M represents the number of emitters of the electric purification component.
[0216] When the emitter i is in the non - discharge state, use the current value of each photosensor as the noise current value Z iThe current value of the first photoreceptor j is taken as the noise current value Z of the first photoreceptor j. ij , the current value of the second photoreceptor k is taken as the noise current value Z of the second photoreceptor k ik .
[0217] Set the first correction coefficient to 2 and the second correction coefficient to 5.
[0218] The first initial current value I xij Subtract the corresponding noise current value (Z ij )The difference △I xij ,Right now:
[0219] △I xij =I xij -Z ij .
[0220] The second initial current value I yik Subtract the corresponding noise current value (Z ik )The difference △I yik ,Right now:
[0221] △I yik =I yik -Z ik .
[0222] Then, the first reference current value R of the first photoreceptor j can be obtained. xij and a second reference current value R of the second photoreceptor k xik ,Right now:
[0223] R xij =2*△I xij , R xik =5*△I yik .
[0224] I xij , Z ij and △I xij Can form array P11[m], I yik , Z ik and △I yik An array P21[m] can be formed, and P11[m] and P21[m] can be stored in independent data storage areas as reference current values of the system.
[0225] When the electric purification component is working, the brightness collection component collects the brightness of the electric purification component in the discharge state at a fixed frequency f, and obtains the array T1[m] of the first current value of the first photoreceptor j and the array T2[m] of the second current value of the second photoreceptor k according to the brightness. T1[m] includes the first current value T xij, T2[m] includes the second current value T of the second photosensor k yik , where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, j represents the serial number of the first photosensor, k represents the serial number of the second photosensor, m represents an integer of M - 1 and satisfies i < m, and M represents the number of emitters of the electric purification component.
[0226] The first current value T of the first photosensor j xij minus the noise current value (Z ij ) of the corresponding first photosensor j to obtain the first current difference △T of the first photosensor j xij , that is:
[0227] △T xij = T xij - Z ij .
[0228] The second current value T of the second photosensor k yik minus the noise current value (Z ik s ) of the corresponding second photosensor k to obtain the second current difference △T of the second photosensor k yik , that is:
[0229] △T yik = T yik - Z ik .
[0230] Analyze the discharge state of each emitter:
[0231] When the second current difference △T of the emitter i yik is less than the second reference current value R xik , that is, △T yik < 5 * △I yik , the electric purification component is in a normal working state. Among them, the second reference current value is adjusted larger through the second correction coefficient to accommodate the influence of factors such as voltage fluctuation of the electric purification component.
[0232] When there exists a second current difference △T of the emitter i yik not less than the second reference current value R xik and the first current difference △T xij is less than the first reference current value R xij , that is, △T yik ≥ 5 * △I yik and △T xij < 2 * △I xij , the discharge state monitoring result indicates that the emitter i is in a state of intensified local ionization. Local ionization intensification occurs in the electric purification component, and an abnormal area is output. It is necessary to repair the electric purification component, such as removing burrs on the corresponding emitter and replacing the corresponding emitter.
[0233] When there is a second current difference ΔT of the emitter i yik not less than the second reference current value R xik and the first current difference ΔT xij not less than the first reference current value R xij when, that is, ΔT yik ≥5*ΔI yik and ΔT xij ≥2*ΔI xij when, the discharge state monitoring result indicates that the emitter i is in a state of intensified overall ionization. It is recommended to replace the electro-purification component. There is an increase in the curvature of some emitters in the electro-purification component, intensified air ionization, the possibility of ozone exceeding the standard and emitter breakage, and there is a risk of electric shock.
[0234] Example 2
[0235] In this example, the first photosensor group and the second photosensor group are adopted. The first photosensor group can be regarded as a relatively large first photosensor, and the second photosensor group can be regarded as a relatively large second photosensor. The method for generating the discharge state monitoring result in this example is similar to the method in Example 1.
[0236] When the electro-purification component is started for the first time, according to the brightness of the electro-purification component in the discharge state, an array P′1[m] of the first initial current values of the first photosensor group and an array P′2[m] of the second initial current values of the second photosensor group are obtained. P′1[m] includes the first initial current value I′ xie of the first photosensor group, and P′2[m] includes the second initial current value I′ yif of the second photosensor group, where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, e represents the serial number of the first photosensor group, f represents the serial number of the second photosensor group, m represents an integer of M - 1 and satisfies i < m, and M represents the number of emitters of the electro-purification component.
[0237] When the emitter i is in the non-discharge state, the current value of each photosensor group is used as the noise current value Z′ i of the photosensor group e. Among them, the current value of the first photosensor group e is used as the noise current value Z′ ie of the first photosensor group e, and the current value of the second photosensor group f is used as the noise current value Z′ if of the second photosensor group f.
[0238] Set the first correction coefficient to 2 and the second correction coefficient to 5.
[0239] The difference ΔI′ obtained by subtracting the corresponding noise current value (Z′ xie ) from the first initial current value I′ ie xie , that is:
[0240] △I′ xie = I′ xie - Z′ ie .
[0241] The second initial current value I′ yif minus the corresponding noise current value (Z′ if ) to obtain the difference value △I′ yif , that is:
[0242] △I′ yif = I′ yif - Z′ if .
[0243] Then, the first reference current value R′ of the first photosensor group e xie and the second reference current value R′ of the second photosensor group f xif can be obtained, that is:
[0244] R′ xie = 2 * △I′ xie , R′ xif = 5 * △I′ yif .
[0245] I′ xie , Z′ ie and △I′ xie can form an array P′11[m], I′ yif , Z′ if and △I′ yif can form an array P′21[m], and P′11[m] and P′21[m] can be stored as the reference current values of the system in independent data storage areas respectively.
[0246] When the electric purification component is working, the brightness acquisition component acquires the brightness of the electric purification component in the discharge state at a fixed frequency f, and obtains an array T′1[m] of the first current values of the first photosensor group e and an array T′2[m] of the second current values of the second photosensor group f according to the brightness. T′1[m] includes the first current value T′ of the first photosensor group e xie , T′2[m] includes the second current value T′ of the second photosensor group f yif , where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, e represents the serial number of the first photosensor group, f represents the serial number of the second photosensor group, m represents an integer of M - 1 and satisfies i < m, and M represents the number of emitters of the electric purification component.
[0247] The first current value T′ of the first photosensor group e xieSubtract the noise current value (Z′) of the corresponding first photoreceptor group e ie ) obtains the first current difference ΔT′ of the first photoreceptor group e xie ,Right now:
[0248] △T′ xie =T′ xie -Z′ ie .
[0249] The second current value T′ of the second photoreceptor group f yif Subtract the noise current value (Z′) of the corresponding second photoreceptor group f if ) obtains the second current difference △T′ of the second photoreceptor group f yif ,Right now:
[0250] △T′ yif =T′ yif -Z′ if .
[0251] Analyze the discharge state of each emitter:
[0252] When the second current difference △T′ of emitter i yif are both less than the second reference current value R′ xif When △T′ yif <5*△I′ yif The electric purification component is in a normal working state. The second reference current value is increased by the second correction coefficient to accommodate the influence of factors such as voltage fluctuation of the electric purification component.
[0253] There is a second current difference △T' at the emitter i yif Not less than the second reference current value R' xif And the first current difference ΔT′ xie are both less than the first reference current value R′ xie When △T′ yif ≥5*△I′ yif And △T′ xie <2*△I′ xie When the discharge state monitoring results indicate that emitter i is in a state of localized ionization aggravation, the electrical purification component experiences localized ionization aggravation and outputs abnormal areas. This requires repair of the electrical purification component, such as removing burrs from the corresponding emitter or replacing the corresponding emitter.
[0254] There is a second current difference △T' at the emitter i yif Not less than the second reference current value R' xif And the first current difference ΔT′ xie Not less than the first reference current value R' xie When △T′ yif≥5*△I′ yif And △T′ xie ≥2*△I′ xie When the discharge status monitoring results indicate that the emitter i is in a state of increased overall ionization, it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component has increased, and air ionization has intensified. There is a possibility of excessive ozone and emitter fracture, which may pose a risk of electric shock.

[0256] This embodiment provides a monitoring system for electric purification components, referring to Figure 6 The monitoring system includes: a receiving module 31, an acquisition module 32 and a monitoring result generation module 33.
[0257] The receiving module 31 is used to receive the current value generated by the brightness acquisition component.
[0258] The acquisition module 32 is used to acquire a reference current value and a noise current value, wherein the reference current value is positively correlated with the initial current value corresponding to the initial time point, and the noise current value is determined by the current value corresponding to when the emitter is in a non-discharging state.
[0259] The monitoring result generating module 33 is used to generate a discharge state monitoring result according to the current value, the reference current value and the noise current value, wherein the discharge state monitoring result is used to indicate whether the emitter is in a normal working state.
[0260] in, Figure 2A This diagram shows the structure of an example electrical purification component B0. The emitter B1 can be a tungsten wire with a diameter no greater than 0.5 mm, and the receiver B2 is a metal plate. The emitter B1 and receiver B2 are spaced apart along a first direction. Due to the structure of electrical purification component B0, emitter B1 is more susceptible to failure or damage than receiver B2 after discharge.
[0261] Reference Figure 2B The light-collecting surface of brightness collection component 2 faces electrical purification component B0. When electrical purification component B0 is in the discharge state, air ionization occurs, increasing the brightness of the air around emitter B1 and generating a corona. Brightness collection component 2 generates a current value based on the collected brightness and sends it to controller 1.
[0262] The initial time point refers to the first use of the electric purification component to be monitored (i.e., the first time it is in a discharge state). At the initial time point, the initial current value of the discharge state of the electric purification component when it is first used is used as one of the reference bases for the normal state.
[0263] The method for obtaining the initial current value is similar to the method for obtaining the current value, and will not be repeated here.
[0264] Due to the electrical properties of electronic components, even if the electrical purification component is not discharging (i.e., in a non-discharging state) and is in a darkroom environment, the brightness collection component will still generate a non-zero current, i.e., the noise current in a darkroom environment. The noise current in an environment with background light is greater than the noise current in a darkroom environment. Therefore, in order to reflect the actual brightness, it is necessary to remove the noise current in the same environment from the current value generated by the collection. The noise current is also one of the reference bases for the normal state of the electrical purification component.
[0265] If an electrical purification component is replaced, the reference current value and noise current value of the replaced component need to be obtained as a reference for the normal state of the electrical purification component. If part of the emitter of the electrical purification component is replaced, the reference current value and noise current value corresponding to the replaced emitter need to be obtained as a reference for the normal state of the emitter.
[0266] In this embodiment, the brightness of the discharge state of the electric purification component is collected by the brightness collection component, and the discharge state monitoring result of the electric purification component is generated according to the brightness, the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, thereby realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault location prompt, thereby improving safety, enhancing user experience, and low cost.
[0267] In a specific implementation, the reference current value includes a first reference current value corresponding to the first current and a second reference current value corresponding to the second current.
[0268] The monitoring result generating module 33 is specifically configured to obtain a first current difference value and a second current difference value by subtracting corresponding noise current values from the current value of the first current and the current value of the second current, respectively.
[0269] The monitoring result generating module 33 is further specifically configured to generate a discharge state monitoring result according to the first current difference, the second current difference, the first reference current value, and the second reference current value.
[0270] Among them, reference Figure 2C The first photoreceptors 211 and the second photoreceptors 212 are arranged at intervals in the first direction. The number and arrangement of the first photoreceptors 211 and the second photoreceptors 212 can be set according to actual needs.
[0271] For each photoreceptor (first or second), the current value it generates in real time corresponds to its reference current value and noise current value. The reference current value and noise current value of the photoreceptor are related to the arrangement position of the photoreceptor relative to the emitter and the electrical performance of the circuit.
[0272] In this embodiment, the brightness of the discharge state of the electric purification component is collected through a photoreceptor array, and the discharge state monitoring result of the electric purification component is generated according to the brightness, the risk state of the emitter is determined, and then corresponding processing is performed according to the risk state, thereby realizing real-time and effective monitoring of the electric purification component. When the electric purification component is abnormal, it can provide component failure warning and fault location prompt, thereby improving safety, enhancing user experience, and low cost.
[0273] In a specific implementation, for each emitter, the monitoring result generating module 33 is further specifically configured to generate a discharge state monitoring result when the second current difference is less than the second reference current value, and the discharge state monitoring result indicates that the corresponding emitter is in a normal working state.
[0274] For each emitter, the monitoring result generation module 33 is further specifically configured to generate a discharge state monitoring result when the second current difference is not less than the second reference current value and the first current differences are both less than the first reference current value, and the discharge state monitoring result indicates that the corresponding emitter is in a locally ionized enhanced state.
[0275] For each emitter, the monitoring result generation module 33 is further specifically configured to generate a discharge state monitoring result when the second current difference is not less than the second reference current value and the first current difference is not less than the first reference current value, and the discharge state monitoring result indicates that the corresponding emitter is in an overall ionization-enhanced state.
[0276] A higher brightness indicates a higher degree of ionization. Because the emitter has an elongated shape, the brightness in the second direction reflects the emitter's overall degree of ionization, allowing for determination of whether the emitter is operating normally. When the corresponding emitter is not operating normally, the first current difference can be used to determine the degree of abnormality in the emitter. The degree of abnormality in a state of increased overall ionization is higher than that in a state of increased local ionization.
[0277] When the emitter is in a state of locally increased ionization, the electrical purification component needs to be repaired, such as removing burrs on the corresponding emitter or replacing the corresponding emitter. When the emitter is in a state of overall increased ionization, it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component increases, and air ionization increases, which may lead to excessive ozone and emitter breakage, posing a risk of electric shock.
[0278] Multiple reference current values may be set according to actual needs to classify the abnormality into multiple abnormality degrees.
[0279] A current difference threshold can be set, positively correlated with a first reference current value. When the corresponding emitter is not operating normally, the coordinates of the first photoreceptor whose first current difference exceeds the threshold are output, providing a fault location indicator. By mapping the coordinates of the first photoreceptor to the plane containing the emitter and receiver, the abnormal area on that plane can be determined.
[0280] In this embodiment, the second current difference is used to determine whether the emitter is in a normal working state. When the emitter is not in a normal working state, the first current difference is used to determine the abnormality degree and abnormal area of the emitter, and then corresponding processing is performed according to the risk status, thereby realizing real-time and effective monitoring of the electrical purification components. When the electrical purification components are abnormal, component failure warnings and fault location prompts can be provided, thereby improving safety, enhancing user experience, and low cost.
[0281] In one embodiment, when the first photoreceptors in the same first photoreceptor group are electrically interconnected and the second photoreceptors in the same second photoreceptor group are electrically interconnected, the sum of the current values of the first photoreceptors in the same first photoreceptor group is the current value generated by the first photoreceptor group, and the sum of the current values of the second photoreceptors in the same second photoreceptor group is the current value generated by the second photoreceptor group. That is, each first photoreceptor group generates only one current value, and each second photoreceptor group also generates only one current value. The first photoreceptor group can be considered as a larger first photoreceptor, and the second photoreceptor group can be considered as a larger second photoreceptor.
[0282] In this case, the number of current values generated by the first and second photoreceptor groups is reduced. Because the reference current and noise current values are determined by the current values of the brightness acquisition component at different time points, the number of corresponding reference and noise current values is also reduced. This reduces the amount of data processing and calculation required for the current values, speeding up the generation of discharge status monitoring results. The method for generating discharge status monitoring results using the first and second photoreceptor groups is similar to the method used when the photoreceptors are not electrically interconnected, and will not be further described here.
[0283] Especially for the filamentary emitter, since the second current with the same coordinate in the first direction does not change much, a second photoreceptor group is used, and each second photoreceptor group generates a second current, which simplifies data processing and calculation, and can meet the need of judging whether the electrical purification component is in normal working condition; a first photoreceptor group is used, and each first photoreceptor group generates a first current, which simplifies data processing and calculation, and can meet the need of fault location when the electrical purification component is not in normal working condition.
[0284] In order to ensure the amount of effective data information, reduce the amount of data processing and calculation, and lower the cost of the device, the number of the first photoreceptor groups is the same as the number of the second photoreceptor groups, and both are integers not greater than 5.
[0285] In a specific implementation, the acquisition module 32 includes: a noise current value acquisition unit 321 , an initial current value acquisition unit 322 , and a reference current value calculation unit 323 .
[0286] The noise current value acquiring unit 321 is configured to acquire a current value corresponding to when the emitter is in a non-discharging state and use the current value in the non-discharging state as the noise current value.
[0287] The initial current value acquisition unit 322 is configured to acquire an initial current value, wherein the initial current value includes a first initial current value corresponding to the first current and a second initial current value corresponding to the second current.
[0288] The reference current value calculation unit 323 is configured to calculate a first reference current value and a second reference current value. The first reference current value is the product of a difference between a first initial current value and a corresponding noise current value and a preset first correction coefficient, and the second reference current value is the product of a difference between a second initial current value and a corresponding noise current value and a preset second correction coefficient.
[0289] The second reference current value is increased by the second correction coefficient, that is, the allowable second current difference range is increased to accommodate the influence of factors such as voltage fluctuation of the electric purification component. The second correction coefficient can be set according to actual needs.
[0290] The first correction coefficient can be set according to actual needs to reasonably distinguish abnormal states of the emitter.
[0291] In this embodiment, a specific implementation method for obtaining a reference current value and a noise current value is provided.
[0292] The following is an example of a method for implementing monitoring of electrical purification components.
[0293] by Figure 2A and 2B Taking the layout of the electric purification component and the monitoring electric purification component as an example, the brightness collection component can collect the brightness of the emitter in different directions in the electric purification component to generate several currents, the current value of which reflects the discharge state of the electric purification component.
[0294] Example 1
[0295] In this example, the photoreceptors are not electrically interconnected with each other, ie, a first photoreceptor group and a second photoreceptor group are not employed.
[0296] When the electro-purification component is started for the first time, an array P1[m] of the first initial current values of the first photosensor and an array P2[m] of the second initial current values of the second photosensor are obtained according to the brightness of the electro-purification component in the discharge state. P1[m] includes the first initial current value I of the first photosensor xij of the first photosensor, and P2[m] includes the second initial current value I yik of the second photosensor, where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, j represents the serial number of the first photosensor, k represents the serial number of the second photosensor, m represents M - 1 and is an integer satisfying i < m, and M represents the number of emitters of the electro-purification component.
[0297] When the emitter i is in the non-discharge state, the current value of each photosensor is used as the noise current value Z i of the photosensor j. Among them, the current value of the first photosensor j is used as the noise current value Z ij of the first photosensor j, and the current value of the second photosensor k is used as the noise current value Z ik of the second photosensor k.
[0298] The first correction coefficient is set to 2, and the second correction coefficient is set to 5.
[0299] The difference △I xij obtained by subtracting the corresponding noise current value (Z ij ) from the first initial current value I xij , that is:[[]]
[0300] △I xij = I xij - Z ij .
[0301] The difference △I yik obtained by subtracting the corresponding noise current value (Z ik ) from the second initial current value I yik , that is:[[]]
[0302] △I yik = I yik - Z ik .
[0303] Then, the first reference current value R xij of the first photosensor jand the second reference current value R xik of the second photosensor kcan be obtained, that is:[[]]
[0304] R xij = 2 * △I xij ,R xik = 5 * △I yik .
[0305] I xij, Z ij and △I xij can form an array P11[m], I yik , Z ik and △I yik can form an array P21[m], and P11[m] and P21[m] can be stored as the reference current values of the system in separate data storage areas respectively.
[0306] When the electro-purification component is working, the brightness acquisition component acquires the brightness of the electro-purification component in the discharge state at a fixed frequency f, and obtains an array T1[m] of the first current values of the first photosensor j and an array T2[m] of the second current values of the second photosensor k according to the brightness. T1[m] includes the first current value T xij of the first photosensor j, and T2[m] includes the second current value T yik of the second photosensor k, where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, j represents the serial number of the first photosensor, k represents the serial number of the second photosensor, m represents M - 1 and is an integer satisfying i < m, and M represents the number of emitters of the electro-purification component.
[0307] The first current value T xij of the first photosensor j minus the corresponding noise current value (Z ij ) of the first photosensor j obtains the first current difference △T xij of the first photosensor j, that is:
[0308] △T xij = T xij - Z ij .
[0309] The second current value T yik of the second photosensor k minus the corresponding noise current value (Z ik ) of the second photosensor k obtains the second current difference △T yik of the second photosensor k, that is:
[0310] △T yik = T yik - Z ik .
[0311] Analyze the discharge state of each emitter:
[0312] When the second current difference △T yik of the emitter i is less than the second reference current value R xik on average, that is, △T yik < 5 * △I<0The electric purification component is in a normal working state. The second reference current value is increased by the second correction coefficient to accommodate the influence of factors such as voltage fluctuation of the electric purification component.
[0313] There is a second current difference △T at the emitter i yik Not less than the second reference current value R xik And the first current difference △T xij are both less than the first reference current value R xij When △T yik ≥5*△I yik And △T xij <2*△I xij When the discharge state monitoring results indicate that emitter i is in a state of localized ionization aggravation, the electrical purification component experiences localized ionization aggravation and outputs abnormal areas. This requires repair of the electrical purification component, such as removing burrs from the corresponding emitter or replacing the corresponding emitter.
[0314] There is a second current difference △T at the emitter i yik Not less than the second reference current value R xik And the first current difference △T xij Not less than the first reference current value R xij When △T yik ≥5*△I yik And △T xij ≥2*△I xij When the discharge status monitoring results indicate that the emitter i is in a state of increased overall ionization, it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component has increased, and air ionization has intensified. There is a possibility of excessive ozone and emitter fracture, which may pose a risk of electric shock.
[0315] Example 2
[0316] This example uses a first photoreceptor group and a second photoreceptor group. The first photoreceptor group can be considered the larger first photoreceptor, and the second photoreceptor group can be considered the larger second photoreceptor. The method for generating the discharge state monitoring results in this example is similar to that in Example 1.
[0317] When the electric purification component is first started, an array of the first initial current value P'1[m] of the first photoreceptor group and an array of the second initial current value P'2[m] of the second photoreceptor group are obtained according to the brightness of the electric purification component in the discharge state. P'1[m] includes the first initial current value I' of the first photoreceptor group. xie , P′2[m] includes the second initial current value I′ of the second photoreceptor group yif, where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, e represents the serial number of the first photosensor group, f represents the serial number of the second photosensor group, m represents M - 1 and is an integer satisfying i < m, and M represents the number of emitters of the electric purification component.
[0318] When the emitter i is in a non-discharging state, the current value of each photosensor group is used as the noise current value Z′ of the photosensor group e i . Among them, the current value of the first photosensor group e is used as the noise current value Z′ of the first photosensor group e ie , and the current value of the second photosensor group f is used as the noise current value Z′ of the second photosensor group f if .
[0319] Set the first correction factor to 2 and the second correction factor to 5.
[0320] The first initial current value I′ xie Subtract the corresponding noise current value (Z′ ie ) to obtain the difference △I′ xie , that is:
[0321] △I′ xie = I′ xie - Z′ ie .
[0322] The second initial current value I′ yif Subtract the corresponding noise current value (Z′ if ) to obtain the difference △I′ yif , that is:
[0323] △I′ yif = I′ yif - Z′ if .
[0324] Then, the first reference current value R′ of the first photosensor group e xie and the second reference current value R′ of the second photosensor group f xif can be obtained, that is:
[0325] R′ xie = 2 * △I′ xie , R′ xif [[ID=6�]] = 5 * △I′ yif .
[0326] I′ xie , Z′ ie and △I′ xie can form an array P′11[m], I′ yif , Z′ if and △I′ yifAn array P'21[m] can be formed, and P'11[m] and P'21[m] can be stored as the reference current values of the system in independent data storage areas respectively.
[0327] When the electro-purification component is working, the brightness acquisition component acquires the brightness of the electro-purification component in the discharge state at a fixed frequency f, and obtains an array T'1[m] of the first current values of the first photosensor group e and an array T'2[m] of the second current values of the second photosensor group f according to the brightness. T'1[m] includes the first current value T' of the first photosensor group e xie , and T'2[m] includes the second current value T' of the second photosensor group f yif , where i represents the serial number of the emitter, x represents the first direction, y represents the second direction, e represents the serial number of the first photosensor group, f represents the serial number of the second photosensor group, m represents an integer of M - 1 and satisfies i < m, and M represents the number of emitters of the electro-purification component.
[0328] The first current value T' of the first photosensor group e xie subtracts the corresponding noise current value (Z' ie ) of the first photosensor group e to obtain the first current difference △T' of the first photosensor group e xie , that is:
[0329] △T' xie = T' xie - Z' ie .
[0330] The second current value T' of the second photosensor group f yif subtracts the corresponding noise current value (Z' if ) of the second photosensor group f to obtain the second current difference △T' of the second photosensor group f yif , that is:
[0331] △T' yif = T' yif - Z' if .
[0332] Analyze the discharge state of each emitter:
[0333] When the second current difference △T' of emitter i yif is less than the second reference current value R' xif for all, that is, △T' yif < 5 * △I' yif , the electro-purification component is in a normal working state. Among them, the second reference current value is adjusted larger by the second correction factor to accommodate the influence of factors such as voltage fluctuation of the electro-purification component.
[0334] When there is a second current difference △T' of emitter iyif Not less than the second reference current value R' xif And the first current difference ΔT′ xie are both less than the first reference current value R′ xie When △T′ yif ≥5*△I′ yif And △T′ xie <2*△I′ xie When the discharge state monitoring results indicate that emitter i is in a state of localized ionization aggravation, the electrical purification component experiences localized ionization aggravation and outputs abnormal areas. This requires repair of the electrical purification component, such as removing burrs from the corresponding emitter or replacing the corresponding emitter.
[0335] There is a second current difference △T' at the emitter i yif Not less than the second reference current value R' xif And the first current difference ΔT′ xie Not less than the first reference current value R' xie When △T′ yif ≥5*△I′ yif And △T′ xie ≥2*△I′ xie When the discharge status monitoring results indicate that the emitter i is in a state of increased overall ionization, it is recommended to replace the electrical purification component. The curvature of some emitters in the electrical purification component has increased, and air ionization has intensified. There is a possibility of excessive ozone and emitter fracture, which may pose a risk of electric shock.
