Description

Technical Field

[0001] The present invention relates to the technical field of automatic operation and maintenance, and specifically relates to an automatic operation and maintenance method and system based on voltage and current monitoring of APs. Background Art

[0002] With the popularization and development of wireless networks, as a key component for connecting wireless devices to a wired Ethernet bridge, an AP (Wireless Access Point) plays an increasingly important role in enterprise and home networks; in order to ensure the stability and reliability of wireless networks, the operation and maintenance management of AP devices becomes crucial; the traditional AP operation and maintenance method usually relies on manual inspections and manual operations, which is not only inefficient but also difficult to detect and solve potential problems in a timely manner, especially in the case of large-scale deployments.

[0003] In addition, long-term operation of AP devices may lead to performance degradation or failures due to various reasons, such as hardware aging, environmental factors, etc. If these problems are not prevented and processed in a timely manner, it will directly affect the service quality of wireless networks; therefore, the demand for automatic operation and maintenance management and intelligent maintenance of AP devices is increasing day by day.

[0004] Deficiencies of the prior art: 1. Lack of real-time monitoring ability: AP operation and maintenance in the prior art often lack real-time monitoring of the device operation status, especially in terms of voltage and current, which makes it difficult to give early warnings of possible failures, thus increasing the risk of service interruption.

[0005] 2. Low operation and maintenance efficiency: The traditional methods of manual inspections and on-site restarts cannot quickly respond to the operation and maintenance requirements of a large number of AP devices. Especially in a large network environment, operation and maintenance personnel need to spend a lot of time and effort to locate and solve problems, seriously affecting work efficiency and service levels.

[0006] 3. Weak fault prediction ability: Most current AP operation and maintenance solutions do not introduce advanced data analysis and machine learning algorithms for intelligent fault prediction. Therefore, effective preventive measures cannot be provided before a failure occurs, increasing the probability and losses of sudden failures.

[0007] 4. Limited remote control function: Although existing remote management solutions can simplify the operation and maintenance process to a certain extent, their functions are relatively simple and cannot meet the requirements of fine control of AP devices in complex environments, such as the ability to perform automated operations according to specific conditions.

[0008] 5. High security risks: Some systems ignore the importance of security encryption during data transmission and are vulnerable to hacker attacks or data leaks, which pose a threat to the network security of enterprises.

[0009] 6. Lack of personalized operation and maintenance strategy: The existing technologies rarely consider the differences in the usage of different AP devices and fail to customize personalized operation and maintenance strategies for each device, such as timed restart, load balancing, etc., thus unable to optimize the use of resources and extend the device life.

[0010] Therefore, there are deficiencies in the existing technologies and further improvements are needed. Summary of the Invention

[0011] In view of the problems existing in the existing technologies, the present invention provides an automatic operation and maintenance method and system for APs based on voltage and current monitoring.

[0012] To achieve the above object, the specific solutions of the present invention are as follows: The present invention provides an automatic operation and maintenance system for APs (Wireless Access Points) based on voltage and current monitoring, and the system includes: Electric control board: It has several power supply ports for supplying power to the AP terminals, and monitors the voltage and current data of each power supply port, and regularly reports this information to the management and control system; Among them, the electric control board calculates the power P of each power supply port by using the following formula: P = U x I; In the formula, U is the voltage and I is the current; by calculating the power, the load condition of the power supply port is reflected, providing a basis for subsequent analysis; Management and control system: Receives and analyzes the voltage and current data from the electric control board, displays the voltage or current information of each power supply port, and when it is impossible to remotely control the restart for abnormal situations, issues an instruction to control the electric control board to perform closing or opening operations on the power supply port to achieve the restart of the AP terminal; and supports setting a timed restart strategy to perform automatic restart during non-working hours, reducing the probability of crashing during working hours.

[0013] Furthermore, the electric control board also has a data preprocessing function to perform preliminary analysis on the voltage and current data before reporting to the management and control system, so as to reduce the amount of data transmitted and improve the response speed of the system; Specifically, the electric control board uses a moving average filtering algorithm to filter the voltage and current data, and the filtering formula is:

[0014] In the formula, Filtered_Value(n) is the current filtered value, Raw_Value(n) is the current raw measured value, α is the filtering coefficient, and the value range is 0 < α < 1. Through this algorithm, the noise and interference in the data can be effectively removed, improving the data quality.

[0015] Furthermore, the management and control system introduces a machine learning algorithm to predict the possible failure time points of the AP by analyzing the historical voltage / current data, and gives an early warning for preventive maintenance; Specifically, the following fault prediction model is adopted: Let the historical voltage data sequence be , and the historical current data sequence be . Construct the feature vector , Use the Support Vector Machine (SVM) algorithm for fault prediction, and its decision function is:

[0016] In the formula, is the Lagrange multiplier; is the sample label (normal or faulty); is the kernel function, which is used to calculate the similarity between the input vector X and the i-th training sample ; b is the bias term. By training this model, early prediction of AP faults can be achieved; i: represents the index of the feature vector , that is, the feature vector of the i-th sample; m: represents the total number of training samples.

[0017] Furthermore, the management control system also supports multi-dimensional data monitoring and analysis. In addition to voltage and current, it also includes parameters such as temperature, signal strength, and data transmission rate to comprehensively evaluate the operating status of the AP device; The following comprehensive evaluation formula is used to calculate the health index H of the AP device:

[0018] In the formula, U, I, T, S, and R are the current values of voltage, current, temperature, signal strength, and data transmission rate respectively, Umax, Imax, Tmax, Smax, and Rmax are the maximum normal values of each parameter, and W1, W2, W3, W4, and W5 are the weight coefficients of each parameter. The operating status of the AP device can be intuitively judged according to the size of the health index H.

[0019] Furthermore, the system establishes a secure encryption channel between the electronic control board and the management control system, and adopts an encryption algorithm and an authentication mechanism to ensure the security and integrity of data transmission, and prevent unauthorized access and malicious attacks; The following encryption algorithm is used to encrypt the data: C = E(K, M) In the formula, C is the ciphertext, E is the encryption function, K is the key, and M is the plaintext data; at the same time, an authentication mechanism based on digital signature is adopted, and the signature formula is: S=Sign(Kprivate,M) In the formula, S is the signature value and Kprivate is the private key. The encryption and authentication mechanism can effectively ensure the security of data transmission.

[0020] The present invention also provides an automatic operation and maintenance method based on voltage and current monitoring AP. Based on the above system, the method includes the following steps: S1, connect the AP device power supply to the power supply port of the electric control board to start the work; S2, the electric control board regularly obtains the voltage and current information of each power supply port and reports these data to the management and control system. The electric control board calculates the power using the formula P=U×I and pre-processes the data according to the sliding average filter algorithm; S3, the management and control system receives and stores the voltage / current information of each power port, displays it on the page, and calculates and finds that when the voltage or current of a power port is abnormal (deviates from the current or voltage during normal operation), it sends an alarm message to the operation and maintenance personnel. At the same time, the SVM fault prediction model is used to analyze historical data and predict the fault time point; S4, the operation and maintenance personnel log in to the management and control system, check the historical data of the power port, determine whether a restart is required, and click the restart button in the management system. The system sends a command to close / open the power port to the electric control board; S5: The electric control board closes / opens the power port according to the received command and restarts the AP. After restarting, the electric control board reacquires the voltage and current information, calculates the power, and reports it to the management and control system. S6, set a scheduled restart strategy for AP devices that are prone to failure after long-term operation, and the management and control system automatically executes the restart command according to the preset schedule. At the same time, the restart strategy is dynamically adjusted according to the health index H of the AP device. When H is lower than the set threshold, the restart operation is performed in advance.

[0021] Furthermore, in step S2, a distributed edge computing architecture is adopted, so that the electric control board performs preliminary data processing and simple fault response, and part of the data processing and decision logic is delegated to the electric control board, which improves the response speed and scalability of the system and reduces the burden on the management and control system.

[0022] Furthermore, in step S3, an intelligent fault prediction step is introduced to predict possible faults by learning a large amount of historical voltage / current data, and to issue an alarm or restart operation in advance, thereby avoiding service interruption.

[0023] Furthermore, in step S5, a restart effect verification step is added. After completing the AP restart operation, the electrical control board re-acquires the voltage and current information of the power port and reports it to the management and control system. The management and control system compares the data before and after the restart to determine whether the restart is successful. If the restart fails, the restart operation is performed again or other troubleshooting measures are taken.

[0024] Furthermore, in step S6, an adaptive restart strategy generation step is added to dynamically adjust the restart strategy according to the usage frequency, load conditions and historical fault records of the AP device, optimize resource utilization, and extend the life of the equipment, including automatically executing the restart command when it is detected that the voltage or current is lower than the normal value for several consecutive cycles.

[0025] The technical solution of the present invention has the following beneficial effects: 1. Improve fault warning capabilities: By monitoring the voltage and current data of AP devices in real time and combining it with machine learning algorithms for intelligent analysis, it is possible to predict possible failures in advance and issue warnings. This allows operation and maintenance personnel to take preventive measures to avoid service interruptions and improve network stability and reliability.

[0026] 2. Enhanced operation and maintenance efficiency: The remote fault diagnosis and restart function is realized, and the operation and maintenance personnel can restart the problematic AP equipment without arriving at the site, which greatly shortens the response time and improves the operation and maintenance efficiency and service quality.

[0027] The introduction of a distributed edge computing architecture has decentralized part of the data processing logic to the electrical control board, reducing the burden on the management and control system and improving the overall response speed of the system.

[0028] 3. Optimize resource utilization: The adaptive restart strategy generation mechanism dynamically adjusts the restart strategy according to the actual usage of the AP device, which not only reduces the number of unnecessary restarts, but also extends the service life of the device and optimizes resource utilization.

[0029] Multi-dimensional data monitoring and analysis functions help to more comprehensively evaluate the operating status of AP devices and provide a scientific basis for operation and maintenance decisions.

[0030] 4. Enhanced security: A secure encrypted channel is established between the electric control panel and the management control system, and advanced encryption algorithms and authentication mechanisms are used to ensure the security and integrity of data transmission, effectively prevent unauthorized access and malicious attacks, and enhance the security of the entire system.

[0031] 5. Provide personalized operation and maintenance strategies: Automatically generate personalized operation and maintenance strategies, such as timed restart, according to the usage frequency, load conditions, and historical fault records of different AP devices to meet the operation and maintenance requirements in a specific environment, further improving the flexibility and pertinence of operation and maintenance.

[0032] 6. Reduce operation and maintenance costs: Due to the realization of automated operation and maintenance management and intelligent fault prediction, the need for manual intervention is reduced, and the labor cost is lowered; at the same time, by extending the equipment life and improving service quality, the additional expenses brought about by equipment replacement or network failures are indirectly reduced.

[0145] Embodiment 4: As Figure 1 shown, the automatic operation and maintenance system for voltage / current monitoring APs proposed in this application includes two major component modules, including an electronic control board and a management control system.

[0146] Among them, the electronic control board has 12 / 16 power supply ports for powering the APs and reporting the voltage / current conditions of each power supply port to the management control system. The management system displays the voltage / current information of each power supply port. For the APs that need to be restarted, the management control system issues instructions to the electronic control board, and the electronic control board completes the closing / opening operations of the power supply ports according to the instructions to operate the restart of the APs.

[0147] The working steps of the automatic operation and maintenance system for voltage / current monitoring APs are as follows: Step 1: The AP power supply is connected to the power supply port of the electronic control board and starts to work.

[0148] Step 2: The electronic control board regularly obtains the voltage and current information of each power supply port and reports it to the management control system.

[0149] Step 3: The management control system receives the voltage and current information of each power supply port, stores it in the database, and displays it on the page.

[0150] Step 4: The management control system calculates and discovers that the voltage or current of a certain power supply port is abnormal and has been lower than the normal value for several consecutive cycles, and sends an alarm message to the operation and maintenance personnel.

[0151] Step 5: The operation and maintenance personnel log in to the management control system, view the voltage and current data of the power supply port, and combine with historical data to determine whether the AP has a fault.

[0152] Step 6: The operation and maintenance personnel click the restart button for a certain power supply port in the management control system. The system sends a command to close / open the power supply port to the electronic control board.

[0153] Step 7: The electronic control board executes the command, performs the operation of closing / opening the power supply for the power supply port, and completes the restart operation of the AP.

[0154] The steps for regularly restarting the AP are as follows: Step 1: The operation and maintenance personnel set a regular restart policy through the management control system. For example, a certain power supply port is restarted at 3:00 am every Monday, Wednesday, and Friday.

[0155] Step 2: The management control system executes the policy and sends a command to close / open the power supply port to the electronic control board at 3:00 am every Monday, Wednesday, and Friday.

[0156] Step 3: The electronic control board executes the command, performs the operation of closing / opening the power supply for the power supply port, and completes the restart operation of the AP.

[0157] Adopting the technology of remotely controlling the power supply of the AP device to solve the problem that when the AP freezes, the current operation and maintenance system cannot connect to and control the AP, and can only manually restart the AP at the fault site, which is an inefficient operation and maintenance method. In addition, for AP devices that are prone to failure during long-term operation, a regular restart policy can be set. By controlling the AP to restart in the early morning, the probability of the AP failing during working hours is reduced, and the network usage experience of teachers and students is improved.

[0158] 1. Restart the AP by remotely controlling the power supply method: When the AP freezes, the current operation and maintenance system cannot connect to and control the AP device, and can only manually restart the AP at the fault site, which is time-consuming and laborious. The present invention can remotely control the restart of the frozen AP device by remotely controlling the power supply of the AP, greatly improving the operation and maintenance efficiency.

[0159] 2. Regularly restart the AP to reduce the failure rate during working hours: For AP devices that are prone to failure during long-term operation, a regular restart policy can be set. By controlling the AP to restart in the early morning, the probability of the AP failing during working hours is reduced, and the network usage experience of teachers and students is improved.

[0160] The above are only the preferred embodiments of the present invention, and do not limit the scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the protection scope of the present invention.
