Description

Technical Field

[0001] The present invention relates to the technical field of environmental control and intelligent monitoring, and particularly to a method and system for monitoring the operating state of a negative ion generator. Background Art

[0002] As a device that can improve air quality and enhance environmental comfort, negative ion generators have been widely used in medical, home, industrial and other fields in recent years. Its core technology lies in ionizing air molecules through a high-voltage electric field to release negative ions, thereby adsorbing harmful substances such as particulate matter and bacteria in the air. In the prior art, there are some deficiencies in the monitoring of the operating state of negative ion generators.

[0003] On the one hand, the existing monitoring methods for negative ion generators usually rely on the collection of a single electrical parameter. For example, only the changes in voltage or current are used to judge the device state, while ignoring the comprehensive influence of multi-dimensional data such as frequency and negative ion concentration. On the other hand, the prior art lacks the ability to synchronously collect and real-time analyze multi-sensor data, resulting in a slow response speed of the monitoring system, being unable to timely adjust the negative ion generation amount and the working state of the device, thus reducing the adaptability and energy efficiency ratio of the device.

Description of the Drawings

[0055] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for description in the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0056] Figure 1 It is a flowchart of the method for monitoring the operating state of the negative ion generator in Embodiment 1.

[0057] Figure 2 It is a schematic diagram of the system for monitoring the operating state of the negative ion generator in Embodiment 1. Detailed Embodiments

[0058] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the detailed embodiments of the present invention will be described in detail below with reference to the drawings of the specification.

[0059] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0060] Second, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.

[0061] Embodiment 1, referring to Figure 1 and Figure 2 , is the first embodiment of the present invention. This embodiment provides a method for monitoring the operating state of a negative ion generator, including the following steps:

[0062] S1. Start the negative ion generator, connect multiple sensors and perform initialization settings.

[0063] Specifically, it includes the following steps.

[0064] Start the negative ion generator through the control panel, connect the voltage sensor, current sensor, and frequency sensor to the negative ion generator using the SPI standard interface. During the connection process, ensure that each sensor is correctly connected, and check whether all physical connections are firm and reliable. In addition, specific parameters of the SPI interface need to be configured, including the clock rate, polarity, and phase, to ensure the accuracy and stability of data transmission;

[0065] The initialization settings include configuring the parameters of multiple sensors and the control center. The sampling frequency represents the number of data points obtained from the sensors per second, which is set by directly accessing the parameter setting interface of the sensors using the control panel. A higher sampling frequency can obtain more detailed data, but it will also cause data redundancy. Therefore, it is necessary to find a balance according to actual needs;

[0066] The range represents the maximum and minimum values that the multiple sensors can measure. Enter the parameter setting page of the sensors using the control panel, and select the maximum and minimum measurement values of the sensors according to the application requirements to ensure that the sensors can provide accurate readings under the expected working conditions;

[0067] The data output format includes digital signals and analog signals. Enter the parameter setting page of the sensors using the control panel and select digital signal output and analog signal output according to the requirements for subsequent data processing and analysis;

[0068] For the negative ion generator, select a suitable working mode and set the output intensity according to the application scenario. For example, in the air purification scenario, it may be necessary to set it to the high-efficiency mode to quickly improve air quality, while in the healthcare environment, a lower output intensity may be required to maintain a comfortable environment. These settings need to be precisely adjusted because they directly affect the performance and energy consumption of the negative ion generator.

[0069] S2. Calibrate the multi-sensors and synchronously collect the data of electrical parameters such as voltage, current, and frequency.

[0070] Specifically, it includes the following steps:

[0071] The multi-sensor calibration process of the negative ion generator includes zero-point calibration and range calibration;

[0072] Zero-point calibration is achieved by placing the sensor in an environment without input signals. With the physical connection disconnected, use the control panel to enter the setting page of each sensor and set the zero-point calibration mode. In this mode, automatically detect and adjust the sensor output to zero, eliminate the inherent offset error, and implement the use of the self-check function and fine-tuning mechanism inside the sensor to ensure that its reference point is accurate;

[0073] Range calibration is achieved by placing the sensor in an environment with standard input signals. The standard input signals here are defined according to the technical specification manuals of each sensor. In specific operations, use a precision power supply to transmit standard input signals to the multi-sensors, access the range calibration interface of the sensors through the control panel, select the corresponding standard values, and start the calibration operation to ensure that the sensor output precisely matches the input standard values;

[0074] After calibration is completed, the main control chip sends a synchronous acquisition instruction to the multi-sensors through the SPI interface and sets the timer interrupt service operation to trigger the data acquisition cycle, achieving precise configuration of the sampling frequency and sampling duration for the multi-sensors. At the same time, adopt the timestamp technology to synchronize the data acquisition time points of each sensor, ensuring that the multi-sensors start recording the data of electrical parameters such as voltage, current, and frequency at the same moment. This synchronous acquisition method effectively avoids data deviation caused by asynchronousness and improves the overall accuracy of data acquisition.

[0075] S3. Preprocess the data of electrical parameters such as voltage, current, and frequency and transfer it to the main control chip of the mobile phone.

[0076] Specifically, it includes the following operations:

[0077] After the synchronous acquisition of data by the multi-sensors is completed, preprocess the data of electrical parameters such as voltage, current, and frequency;

[0078] Adopt an adaptive noise algorithm for spectral analysis to identify and eliminate the influence of noise. First, collect a data sample, convert it to the frequency domain through the fast Fourier transform technology to clearly see each frequency component in the signal, and then analyze based on the spectral characteristics. The algorithm automatically identifies abnormal high-frequency or low-frequency noise components and removes these noises by adjusting the filter parameters. For example, when significant background noise is found in a specific frequency band, dynamically adjust the filtering intensity of that frequency band to ensure that the noise is effectively suppressed without affecting the useful signal;

[0079] An adaptive filtering algorithm is used to set a band-stop filter to remove electromagnetic interference. First, the main interference frequency range is determined through detailed spectrum analysis. After determining the interference frequencies, the band-stop filter is set to shield these frequencies. The MATLAB tool is used to configure the specific parameters of the filter, including the center frequency and bandwidth. In actual operation, the filter settings need to be continuously adjusted according to the specific environmental conditions until the best effect is achieved. This flexible adaptive filtering method not only improves the purity of the data but also lays a foundation for subsequent accurate data analysis;

[0080] The Min-max normalization technique is used for normalization operations to map all electrical parameter data of voltage, current, and frequency to the same scale. First, the maximum and minimum values of each electrical parameter are obtained and converted according to the formula as follows:

[0081]

[0082] where X n represents the data value after normalization processing, X represents the originally collected data value, X min represents the minimum value in the collected dataset, and X max represents the maximum value in the collected dataset;

[0083] Through the above formula, all electrical parameters are mapped to the same scale, enabling comparison and analysis on the same basis, thus simplifying the subsequent data processing flow;

[0084] After completing the preprocessing operations, the data format is converted. The analog-to-digital converter (ADC) is used to convert the analog signal into a digital signal and encode it in binary format. In this process, the analog signal is first quantized into discrete values and then converted into binary code for easy storage and transmission. To ensure the accuracy of the conversion, an appropriate resolution needs to be selected, usually 12 bits or more, to ensure sufficient detail retention;

[0085] After completing the format conversion operation, the I2C communication protocol is used to transfer the data from the multi-sensor to the main control chip on the mobile phone. I2C is a simple and effective serial communication protocol suitable for data exchange between multiple devices within a short distance. By pre-configuring the I2C address and baud rate, the data is ensured to be efficiently and accurately transferred to the main control chip, providing a basis for the main control chip to further analyze this data and obtain the current negative ion concentration. At the same time, it improves the accuracy of data processing and also provides a reliable guarantee for subsequent data analysis and decision support.

[0086] S4. Use the main control chip to analyze the preprocessed electrical parameter data of voltage, current, and frequency to obtain the current negative ion concentration.

[0087] Specifically, the following operations are included:

[0088] After completing the preprocessing operation, the main control chip starts to perform data analysis operations;

[0089] Utilize peak detection to extract the voltage intensity during the operation of the negative ion generator. By combining historical data according to application requirements, set a suitable threshold for the preprocessed voltage signal data to distinguish background noise from the actual voltage signal peak. Scan the voltage signal data sequence point by point, find the data points that exceed the threshold, and record each data point that exceeds the threshold and its timestamp. For each data point that exceeds the threshold, check several adjacent points before and after it to confirm whether a local maximum is formed. If a point is higher than all its adjacent points before and after and exceeds the threshold, it is marked as a peak point. Finally, select the maximum value from all the identified peak points as the voltage intensity, and perform a preliminary verification on it. After ensuring that it meets the expected range, output and store it;

[0090] Utilize RMS (Root Mean Square) to extract the current intensity during the operation of the negative ion generator. Select a suitable time window according to the periodicity of the signal and application requirements to calculate the root mean square value of the current signal. Within the selected time window, perform a square operation on the current signal data to eliminate the influence of the current direction. After squaring, the positive and negative alternating current signals both become positive values, so that the effective value of the current can be accurately obtained. Calculate the average value of the squared current signal within the entire time window, and take the square root of the average value to obtain the root mean square value of the current signal, that is, the current intensity, which can better reflect the actual effect of the current;

[0091] Utilize FFT (Fast Fourier Transform) to extract the operating frequency during the operation of the negative ion generator. The main control chip loads the preprocessed current and voltage signal data from the buffer area, divides the continuous signal into segments of appropriate length, usually selects a power of 2 length such as 512 or 1024 points to optimize the efficiency of the FFT algorithm. At the same time, in order to avoid spectral leakage caused by the truncation effect, apply Hanning window and Hamming window functions to each data segment, perform the fast Fourier transform, convert the time-domain signal to a frequency-domain representation, extract the amplitude information from the FFT result, construct a single-sided spectrogram, and find the frequency component with the largest amplitude to obtain the final operating frequency;

[0092] Based on the extracted voltage, current intensity, and operating frequency during the operation of the negative ion generator, calculate the negative ion concentration, and its expression is:

[0093]

[0094] C represents the negative ion concentration, E(V, I, f) represents the negative ion generation efficiency, δ represents the adjustment coefficient of the voltage linear term, V represents the voltage, ∈ represents the adjustment coefficient of the current linear term, I represents the current, ζ represents the adjustment coefficient of the frequency linear term, f represents the frequency, and η represents the adjustment coefficient of the interaction term of voltage, current and frequency;

[0095] Among them, the expression of E(V, I, f) representing the negative ion generation efficiency is:

[0096]

[0097] E(V, I, f) represents the negative ion generation efficiency, V represents the voltage, I represents the current, f represents the frequency, and α V represents the proportionality constant of the voltage square term, and β I represents the proportionality constant of the current square term, and γ f represents the proportionality constant of the frequency square term;

[0098] The above operations demonstrate a scheme for data analysis to obtain the negative ion concentration. This scheme can not only improve the accuracy of negative ion concentration calculation, but also provide a solid scientific basis for subsequent optimization.

[0099] S5. Based on the current negative ion concentration, compare it with the set target value, and monitor the working efficiency, energy consumption situation and potential fault information of the negative ion generator to generate an evaluation report.

[0100] Specifically, the following operations are included.

[0101] When comprehensively monitoring the operating status of the negative ion generator, it is first necessary to set a clear target value. The main control chip generates the target value according to the indoor air quality standard, user requirements and manufacturer's recommended value, where:

[0102] The air quality standard is formulated by health and environmental protection agencies based on scientific research, which defines the appropriate negative ion concentration range in different environments. The user requirements are determined according to the specific application scenarios and personal preferences, and the required negative ion concentration is clarified through user surveys and feedback. The manufacturer's recommended value is based on equipment performance tests and technical specifications, and provides the best setting suggestions for negative ion concentration and operating parameters, including voltage, current and frequency, provided by the manufacturer;

[0103] The working efficiency, energy consumption threshold and standard parameter ranges of voltage, current and frequency of the equipment are also determined according to user requirements and manufacturer's recommended values, which not only ensure that the equipment operating parameters meet strict safety and efficiency standards, improve reliability and stability, but also enable the negative ion generator to adapt to different usage scenarios and requirements;

[0104] The specific steps to obtain the working efficiency are as follows: compare the currently measured negative ion concentration with the preset target concentration through the main control chip, calculate the concentration deviation. To improve the accuracy, the method of taking the average of multiple measurements can be used to reduce the influence of random errors. Calculate the working efficiency of the device according to the concentration deviation, that is, divide the current concentration by the target concentration and then multiply by 100%. For example, the current concentration is 80,000 per cm 3 , and the target concentration is 100,000 per cm 3 , then the working efficiency is 80%. Set a reasonable efficiency threshold based on historical performance data for the working efficiency. When the obtained working efficiency is lower than the efficiency threshold, the negative ion generator will automatically trigger the alarm mechanism. The above process provides a quantitative concentration deviation index to measure the working efficiency of the negative ion generator, facilitating the timely discovery and solution of problems;

[0105] The specific steps to obtain the energy consumption situation are as follows: calculate the total energy consumption by combining the voltage and current data collected by the main control chip with the running time of the negative ion generator. For example, the voltage is 10V, the current is 2A, and the running time is 1 hour, then the energy consumption is 20Wh. To more accurately reflect the actual energy consumption, the method of piecewise integration can be used to handle the case of non-constant load. Set a reasonable energy efficiency threshold for the energy consumption situation based on historical performance data. Compare the calculated energy consumption with the energy consumption threshold. If the energy consumption exceeds the threshold, check the power supply module and circuit connection to confirm whether there is energy waste and potential faults. Reduce the energy consumption by adjusting the working mode and replacing high-efficiency components. The above process effectively monitors the energy consumption, achieving the purpose of saving energy and reducing environmental impact;

[0106] The specific steps to obtain potential fault information are as follows: real-time monitor the operating parameters of the negative ion generator under different voltage and current working conditions, including voltage, current, frequency, and negative ion concentration. Set multiple monitoring points to obtain the operating parameters to improve the detection accuracy. Compare the monitored operating parameters with the set standard parameter range. For example, the standard voltage range is 9 - 11V, the standard current range is 1.8 - 2.2A, and the standard frequency range is 48 - 52kHz. If the operating parameters deviate from the standard range, the main control chip records the deviation value and analyzes the potential fault information. When the voltage exceeds the standard range, there may be a high-voltage module fault. Abnormal current may indicate overloading and internal short circuit. Abnormal frequency may indicate problems with the oscillation circuit. Predict the development trend of potential faults according to historical data and the long short-term memory network algorithm, give early warnings to improve safety, reduce the risk of unexpected shutdowns, and extend the service life of the device;

[0107] Integrating the above steps, a detailed evaluation report is finally generated. The content of the report includes:

[0108] The deviation between the current negative ion concentration and the target concentration;

[0109] The working efficiency of the device;

[0110] The energy consumption of the device;

[0111] Potential fault information, including abnormal voltage, abnormal current, and abnormal frequency;

[0112] Summary of the operating status, including normal status, decreased efficiency, excessive energy consumption, and potential faults.

[0113] S6. Based on the evaluation report, generate a processing strategy to adjust the output power of the high-voltage module through the main control chip and adjust the amount of negative ion generation.

[0114] Specifically, the following operations are included.

[0115] Analyze the key information of the evaluation report, and determine the adjustment direction and adjustment amount of the output power of the high-voltage module through the main control chip according to the negative ion concentration deviation. For example, if the negative ion concentration in the current environment is lower than the target value concentration, the output power needs to be increased, and vice versa. At the same time, the main control chip will also comprehensively consider the working efficiency and energy consumption to ensure the effectiveness of the adjustment;

[0116] Substitute the negative ion concentration deviation and generation efficiency into the formula to calculate the output power adjustment amount of the high-voltage module. The specific formula is as follows:

[0117]

[0118] Where ΔP represents the output power adjustment amount of the high-voltage module, ΔC represents the deviation between the current negative ion concentration and the set target value concentration, E(V, I, f) represents the negative ion generation efficiency, V represents voltage, I represents current, and f represents frequency;

[0119] The design of this formula aims to balance the relationship between the negative ion concentration deviation and the current operating status of the negative ion generator, thereby controlling the change amount of the output power and making the adjustment process more accurate;

[0120] The main control chip reads the current output power value from the high-voltage module and adds it to the output power adjustment amount obtained from the above formula to obtain the target output power;

[0121] According to the target output power, using the gradient descent optimization algorithm, the main control chip gradually fine-tunes the voltage, current, and frequency parameters. In each iteration of the gradient descent, update the values of each parameter according to the gradient information calculated in the previous step, and re-obtain the amount of negative ion generation. If the expected effect is not achieved, continue to adjust the parameters until an optimized parameter combination that can make the amount of negative ion generation reach the target value is found, and gather all the optimized parameters together to generate an optimization plan for the user to view and subsequent analysis;

[0122] The above process realizes the precise control of the parameters of the high-voltage module, ensures the stability and controllability of the negative ion generation amount, and at the same time provides a flexible adjustment mechanism, enabling the negative ion generator to quickly respond to changes in the operating state.

[0123] S7. Send the parameter optimization scheme to the mobile phone user terminal to achieve further regulation.

[0124] Specifically, it includes the following steps:

[0125] Convert the parameter optimization scheme into a data format suitable for transmission, package it into a data packet, and send it to the mobile phone user terminal through wireless communication protocols including Wi-Fi and Bluetooth;

[0126] After the mobile phone terminal receives the optimization scheme, it displays detailed adjustment suggestions and the current device status on the user interface. Users can intuitively see the current voltage, current, and frequency settings as well as the recommended optimized parameter values. Users can choose to manually confirm these adjustments or enable the automatic mode to execute the optimization scheme. This interaction method not only improves user participation and control flexibility but also allows users to manually adjust according to the actual situation. For example, if users want to reduce energy consumption at night, they can choose to manually lower certain parameters, and during high-demand periods during the day, users can choose the automatic mode to ensure that the device is always in the best performance state;

[0127] When users confirm the adjustment suggestions, the mobile phone application will send the instructions back to the main control chip to perform the corresponding parameter adjustments. During this process, the mobile phone application and the main control chip maintain real-time communication to ensure that all instructions can be accurately conveyed and executed. At the same time, the mobile phone application provides a real-time monitoring function, allowing users to view the changes in key indicators such as negative ion concentration, working efficiency, and energy consumption at any time. Through charts and numbers, users can intuitively understand the operating state of the negative ion generator;

[0128] After completing the parameter adjustment, the mobile phone application continues to collect the operating data of the device and feedback it to the main control chip for further optimization analysis. By using these feedback data to continuously learn and improve, the self-adjustment ability is gradually enhanced. For example, when a certain specific parameter combination has shown good performance in the past multiple times, the negative ion generator may prefer a similar combination in the future.
