Description

Technical Field

[0001] The present invention relates to technical fields such as WIFI and wireless Internet access, and particularly relates to an intelligent detection method and system for a portable WIFI device. Background Art

[0002] A portable WIFI device is a wireless Internet access device with an IoT card installed inside. Through the mobile communication network, the IoT card can connect the traffic usage device wirelessly connected to the portable WIFI device to the Internet to achieve data transmission. Usually, a portable WIFI device supports the communication networks of multiple communication operators. For example, a portable WIFI device can support the mobile network, the Unicom network, or the Telecom network. Although the traffic service is provided by the communication network of the communication operator, the communication operator does not directly face the users of the portable WIFI device. This results in a large number of customer services being required to serve the users of the portable WIFI device after the device is provided to the users at the factory, collecting the quality problems of the portable WIFI device feedback by the users, and causing the operation and maintenance cost of the portable WIFI device to increase. For the quality problems of the portable WIFI device before leaving the factory, enterprises also need to develop a special quality inspection system for detection, resulting in an increase in the quality inspection cost of the portable WIFI device. In addition, after the portable WIFI device is provided to the users at the factory, for the quality problems of the portable WIFI device, it can only rely on the users to actively contact the customer service for feedback. The users cannot perform self-detection, and the device management system of the portable WIFI device cannot perform automatic detection either. Moreover, for other device performance detections other than device quality problems, there is no corresponding solution after the portable WIFI device leaves the factory, making it impossible for both the users and the operation and maintenance department of the portable WIFI device to independently understand the performance status of the portable WIFI device and unable to reasonably respond in a timely manner according to the performance status of the portable WIFI device.

[0003] In summary, the existing portable WIFI devices cannot uniformly detect device problems and performance status before and after leaving the factory, cannot uniformly support users and device enterprises for self-detection, resulting in an increase in the costs of device enterprises, and the device usage experience of device users needs to be improved. Summary of the Invention

[0019] Embodiment 1

[0020] Refer to Figures 1 - 3 , this embodiment provides an intelligent detection method for a portable WI-FI device, including step S101, step S102, and step S103. Among them, step S101, step S102, and step S103 can be run on the server.

When it is determined that the device detection request is a device status detection request initiated by the user side, communicate with the detection module in the portable WI-FI device, and control the detection module to detect the fault and / or performance of the portable WI-FI device according to the detection authority of the user side, so as to obtain a device status detection report and provide it to the user side, thereby uniformly detecting device problems and performance status, uniformly supporting users and device enterprises to perform independent detection, reducing the costs of device enterprises, and improving the device usage experience of device users.

[0021] Refer to Figure 3 , Figure 3 shows a schematic architecture diagram of the server in this embodiment. It should be noted that the server, as the execution subject of all or part of the steps in the intelligent detection method for the portable WI-FI device, in addition to being able to execute step S101, step S102, and step S103 in this embodiment, can also run part or all of the steps of the methods involved hereinafter.

[0022] From Figure 3It can be known that the server can be an information processing device including a memory, a processor, and a network interface that are communicatively connected to each other through a system bus. Those skilled in the art of this technology can understand that the server here is a device capable of automatically performing numerical calculations and / or information processing according to pre-set or stored instructions, and its hardware includes but is not limited to a microprocessor, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a digital signal processor (DSP), an embedded device, etc. The server can perform human-computer interaction with the user through a touchpad or a voice control device, etc. The memory includes at least one type of readable storage medium, and the readable storage medium includes flash memory, a hard disk, a multimedia card, a card-type memory (such as an SD or DX memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, etc. In some embodiments, the memory can be an internal storage unit of the server, such as the hard disk or memory of the server. In other embodiments, the memory can also be an external storage device of the server, such as a plug-in hard disk equipped on the server, a smart media card (SMC), a secure digital (SD) card, a flash card, etc. Of course, the memory can also include both the internal storage unit of the server and its external storage devices.

[0023] See Figures 1 - 3 , an intelligent detection method for a portable WIFI device, including step S101, step S102, and step S103.

[0024] Step S101, receiving a device detection request, and determining whether the device detection request is a device operation and maintenance detection request initiated by the enterprise side of the device or a device status detection request initiated by the user side. The detection request content of the device operation and maintenance detection request includes fault detection and performance detection of the portable WIFI device before and after leaving the factory, and the detection request content of the device status detection request includes fault detection and performance detection of the portable WIFI device after leaving the factory;

[0025] Step S102, when it is determined that the device detection request is a device operation and maintenance detection request initiated by the device enterprise side, communicate with the detection module in the portable WIFI device, and control the detection module to detect the faults and / or performance of the portable WIFI device according to the detection permissions of the device enterprise side, so as to obtain a device operation and maintenance detection report and provide it to the device enterprise side;

[0026] Step S103, when it is determined that the device detection request is a device status detection request initiated by the user side, communicate with the detection module in the portable WIFI device, and control the detection module to detect the faults and / or performance of the portable WIFI device according to the detection permissions of the user side, so as to obtain a device status detection report and provide it to the user side; the device detection content corresponding to the detection permissions of the user side is less than the device detection content corresponding to the detection permissions of the device enterprise side.

[0027] It should be noted that in this embodiment, when a detection request arrives, it is first determined whether the request is initiated by the device enterprise side or the user side; if it is initiated by the device enterprise side (operation and maintenance detection request), the faults and / or performance are detected through the detection module in the device to obtain an operation and maintenance detection report; if it is initiated by the user side (status detection request), the faults and / or performance are also detected through the detection module, but a device status detection report is generated based on the user side permissions and the result is provided to the device enterprise side. Through the above unified detection process, the portable WIFI device can perform integrated detection of faults and performance before and after leaving the factory. It should be noted that in the prior art, enterprises need to use a special quality inspection system to detect device faults and performance before leaving the factory, and rely on customer service or user feedback to obtain device fault and performance information after leaving the factory, unable to form a coherent detection method, and the operation and maintenance and quality detection costs are high. In this embodiment, by establishing a unified intelligent detection mechanism: whether it is batch detection before leaving the factory, remote detection after leaving the factory, or self-check by the user side, all are based on the same detection module and process, thus effectively reducing the cost of enterprises maintaining multiple systems and also reducing the cost of manual intervention. It should also be noted that in the prior art, users can only discover problems with the device and then feedback through customer service; the enterprise side cannot actively perform large-scale performance detection or fault diagnosis on devices after leaving the factory, and users cannot perform simple self-checks by themselves. In this embodiment, through the detection module built into the portable WIFI device, detection permissions are set for both the enterprise side and the user side, so users can initiate detections by themselves when needed, and enterprises can also remotely diagnose devices when necessary, so as to timely obtain the device health status and take measures.

[0028] It should also be noted that device enterprises usually require deeper and more comprehensive data (fault logs, hardware metrics, communication module performance, etc.), which includes both pre - factory production quality inspection and post - factory remote maintenance and batch diagnosis. Therefore, their detection requests pay more attention to the breadth and depth of "operation and maintenance detection". The user side is more concerned about the fault conditions and basic performance indicators (network signal stability, network speed, traffic status, etc.) of the device during actual use. The detection permissions and detection targets are relatively limited, aiming to quickly locate common faults and improve the personal use experience. Therefore, in this embodiment, the device detection content corresponding to the detection permission of the user side is less than the device detection content corresponding to the detection permission of the device enterprise side. Since users and enterprises have different detection purposes, concerns, and accessible data ranges, by distinguishing the sources of detection requests, permissions can be reasonably allocated. The enterprise side has higher - level detection permissions; the user side can only initiate detections related to the use experience of its own devices. This can not only avoid the risk of enterprises over - collecting user data but also allow users to perform simple self - detections. On the one hand, the enterprise side can detect device faults and performance at different stages (before and after factory) in a unified platform, quickly locate and handle problems; on the other hand, the user side can also obtain a self - detection function in the same platform without the need for additional customer service intervention. By having the device detection content corresponding to the detection permission of the user side less than the device detection content corresponding to the detection permission of the device enterprise side, integrated detection, permission - level management, and improved detection efficiency can be achieved technically, which can significantly reduce the operation and maintenance and quality inspection costs of enterprises and improve the user experience.

[0029] In some preferred embodiments, when controlling the detection module to detect the faults and / or performance of the portable Wi-Fi device according to the detection permissions of the device enterprise end, it includes: sending an initialization instruction to the detection module in the portable Wi-Fi device, controlling the detection module to preset and load the detection permissions and detection parameters of the device enterprise end, and detecting the faults and / or performance of the portable Wi-Fi device according to the loaded detection permissions and detection parameters. It should be noted that in this embodiment, through the pre-operation of sending an initialization instruction to the detection module in the portable Wi-Fi device, the detection permissions and detection parameters required by the enterprise end are loaded into the detection module before the detection starts, avoiding the uncertainties brought by temporarily obtaining or switching permissions during the detection process. The enterprise end permissions and parameters are loaded before the detection starts, ensuring that the detection module executes based on the latest and most complete permission scope and detection parameters. This can reduce the situations of insufficient permissions, incomplete parameters, or loading errors during the detection process, improving the detection accuracy and stability. By pre-loading the detection parameters required by the enterprise end, the detection module can complete a comprehensive detection of faults and / or performance at one time when executing the detection, without the need to dynamically call or adjust the detection configuration during the detection process, avoiding the overhead of repeated loading and improving the detection efficiency. In addition, separating the initialization instruction from the fault / performance detection link enables the detection module to have better modular management capabilities. For example, when it is necessary to upgrade the detection permissions of the enterprise end or add new detection parameters, only corresponding configurations and loadings need to be performed in the initialization stage, without the need to make major changes to the subsequent detection process, facilitating later expansion and maintenance.

[0030] In some preferred embodiments, when controlling the detection module to detect the faults and / or performance of the portable Wi-Fi device according to the detection permissions of the client, the following steps are included: sending an initialization instruction to the detection module in the portable Wi-Fi device, controlling the detection module to preset and load the detection permissions and detection parameters of the client, and detecting the faults and / or performance of the portable Wi-Fi device according to the loaded detection permissions and detection parameters. It should be noted that in this embodiment, by sending an initialization instruction to the detection module in the portable Wi-Fi device and loading the permissions and detection parameters of the client into the detection module before the detection starts, it is possible to avoid situations such as missing permissions, incomplete parameters, or improper loading during the detection process, and improve the reliability of the detection results from the source. In addition, by preloading the permissions and parameters before the detection process, the detection module does not need to perform dynamic adjustments or repeated confirmations when performing fault and / or performance detections, improving the detection efficiency and reducing additional resource consumption. In addition, by separating the initialization instruction from the two stages of fault detection / performance detection, when it is necessary to upgrade the detection parameters of the client or adjust the permission scope, only the configuration in the initialization process needs to be updated, without making large-scale changes to the detection process, achieving better scalability and maintainability. In addition, since the detection permissions of the client are less than those of the enterprise side, clearly defining the data range and detection item content that the client can access during the initialization stage can effectively prevent the client from accessing beyond its authority and better protect the data security and privacy of both the user and the enterprise.

[0031] In some preferred embodiments, after obtaining the device operation and maintenance detection report, the device operation and maintenance detection report is compared with the pre-stored historical detection information to obtain the fault or performance change trend information of the portable Wi-Fi device; the change amplitude of the fault or performance change trend information of the portable Wi-Fi device is monitored, and when the change amplitude of the fault or performance change trend information of the portable Wi-Fi device exceeds the threshold, a warning message is sent to the enterprise end of the device to prompt the enterprise end of the device to actively contact the user end to provide maintenance. It should be noted that in this embodiment, by comparing the new detection report with the pre-stored historical detection information, the change trend of the fault or performance index of the portable Wi-Fi device can be identified. Compared with only judging based on the single detection result, trend analysis can more accurately reflect the true operating state of the device and help the enterprise end discover potential fault hazards in time. When judging whether the fault or performance change trend information of the portable Wi-Fi device exceeds the preset threshold, if it exceeds the limit, a warning message is immediately automatically sent to the enterprise end to realize the active push of the abnormal situation of the device. This mechanism enables the enterprise end to intervene before the device fault deteriorates, reducing the risk of major faults or device downtime. Once the enterprise end receives the warning message, it can actively contact the user end to provide timely remote guidance or on-site maintenance, shortening the interruption time of the user's use due to the device fault. By proactive maintenance instead of passive waiting for user feedback, the user experience can be significantly improved and the after-sales service cost can be reduced.

[0032] In some preferred embodiments, after obtaining the device status detection report, the device status detection report is compared with the pre-stored historical detection information to obtain the fault or performance change trend information of the portable Wi-Fi device; the change amplitude of the fault or performance change trend information of the portable Wi-Fi device is monitored, and when the change amplitude of the fault or performance change trend information of the portable Wi-Fi device exceeds the threshold, a warning message is sent to the enterprise side of the device to prompt the enterprise side of the device to actively contact the user side to provide maintenance. It should be noted that not only the detection reports of the enterprise side will be compared with the historical information, but also the detection reports of the user side can be used for trend analysis. In this way, the reports of both the enterprise side and the user side can be incorporated into the same historical database for comparison and evaluation, further improving the comprehensive device detection and monitoring system. Even for the detection requests initiated by the user side, once the detection results show that the device fault or performance fluctuation exceeds the threshold, it will automatically trigger a warning to the enterprise side. Compared with the user side's self-judgment of the severity of the fault, this unified warning mechanism can remind the enterprise side to intervene in maintenance more timely and accurately, preventing the user side from ignoring potential risks and leading to the aggravation of the fault. The enterprise side can not only understand the device status from the operation and maintenance detection reports initiated by itself, but also use the detection reports of the user side to master more real-time and first-line device status information. When the trend monitoring results show significant anomalies, the enterprise side can take the initiative to contact the user side and arrange remote diagnosis or on-site maintenance in advance. When the device status detection report shows potential fault signs, the user side does not need to passively contact the enterprise customer service after the fault occurs, but the enterprise side takes the lead in mastering the device anomalies and actively provides maintenance solutions. For users, this greatly shortens the fault handling cycle and reduces the use interruption or inconvenience caused by device problems.

[0033] In some preferred embodiments, the device operation and maintenance detection report includes a device exception report when the hardware operating temperature, power supply voltage of the portable Wi-Fi device, and the status of the communication module are abnormal; the device status detection report includes a device exception report when the hardware operating temperature, power supply voltage of the portable Wi-Fi device, and the status of the communication module are abnormal. It should be noted that in this embodiment, by clarifying that the detection reports at the enterprise side and the user side must include a device exception report when the hardware operating temperature, power supply voltage, or the status of the communication module is abnormal. In this way, both the operation and maintenance detection report and the status detection report can capture and display these core fault points in the first time, ensuring the consistency of the comparison and analysis of the report content. In addition, listing the abnormal hardware operating temperature, power supply voltage, and communication module status as key monitoring indicators can effectively capture most common and serious hardware failures (such as overheating, power failure, communication interruption, etc.). During actual maintenance or troubleshooting, the enterprise side can more quickly lock down the root cause of the problem and shorten the fault diagnosis cycle. Even if the user side's detection permissions are relatively limited, the same exception report items can still be used to confirm the current most critical fault condition of the device, keeping the information consistent with that obtained by the enterprise side. This allows the user side to more quickly understand the true state of the device and also facilitates the use of the same indicator system by the enterprise side and the user side in subsequent communication, improving communication efficiency. In addition, after incorporating the hardware operating temperature, power supply voltage, and communication module status into a unified exception report system, potential dangerous trends (such as continuous temperature increase, abnormal voltage fluctuation, etc.) can be identified at an early stage, enabling early intervention and maintenance. Compared with simply detecting the network rate or traffic status, it can better avoid the occurrence of serious failures.

[0034] In some preferred embodiments, after receiving a device status detection request initiated by the client, the client permission information is sent to the detection module, and the detection module is triggered to record the initiation time and detection content of this detection. It should be noted that after receiving the detection request initiated by the client, the client permission information is sent to the detection module to prevent the detection module from performing detection under default or incorrect permissions, thereby ensuring that the detection content is strictly limited to the scope accessible by the client and improving data security and compliance. By recording the initiation time and detection content of this detection, the specific detection process of each client request can be accurately located during subsequent problem troubleshooting or historical comparison, including when the detection was performed, which items were detected, and whether there are differences from the detection results in other time periods. When the enterprise side views the overall usage status of the portable WI-FI device or conducts fault tracing, the timestamp and detection scope of each detection triggered by the client can be extracted from the log. Comparing the detection records at different time points can help the enterprise side better understand the operation of the device in the actual usage scenario of the client and provide more targeted maintenance and upgrade plans. Since the client permission information can be loaded and recorded during the request phase, it is possible to identify whether the current detection is duplicate or conflicting with previous detections based on this record, thereby optimizing resource scheduling and the operation efficiency of the detection module.

[0035] In some preferred embodiments, after generating the device status detection report, the summary information of network connection stability, traffic usage, and fault type in the device status detection report is fed back to the user terminal; the complete information of the device status detection report is saved in the secure storage area of the portable Wi-Fi device for comparative analysis when the enterprise terminal initiates a device operation and maintenance detection request subsequently. It should be noted that the user terminal only needs to focus on the key indicators most closely related to daily use (such as network connection stability, traffic usage, and fault type summary), so only feeding back this simplified and easy-to-understand summary information to the user terminal helps the user quickly grasp the device operation status and make corresponding adjustments. Avoid showing overly professional or detailed information to ordinary users, reducing unnecessary troubles or misunderstandings for users. And saving the complete information of the detection report in the secure storage area of the portable Wi-Fi device ensures the integrity and security of the data. When the enterprise terminal initiates a device operation and maintenance detection request subsequently, it can access and compare the previous complete detection report for long-term trend analysis, fault tracing, or performance optimization research, greatly improving the accuracy and efficiency of enterprise operation and maintenance and quality inspection. It can be understood that in this embodiment, by distinguishing the summary information from the complete report, access management at different permission levels can be achieved: the user terminal can only view part of the information within its permission range, while the enterprise terminal can read all the content according to higher permissions. This measure not only meets the usage needs of users but also guarantees the data requirements of the enterprise terminal in fault diagnosis and product maintenance. When the user terminal discovers serious or frequent fault type prompts in the summary information, it can contact the enterprise terminal in a timely manner; the enterprise terminal can obtain detailed information by accessing the complete report in the device secure storage area, quickly locate the problem, and propose a solution, effectively shortening the troubleshooting and repair cycle and enhancing the user experience.

[0036] In some preferred embodiments, after determining that the device detection request is a device operation and maintenance detection request initiated by the enterprise side of the device, an extended detection permission is assigned to the detection module and a fault log acquisition program is initialized; before obtaining the device operation and maintenance detection report, the communication module log, hardware monitoring log, and system operation log of the portable WIFI device are extracted, and a multi-dimensional log data set is merged and generated; based on the multi-dimensional log data set, a log aggregation and anomaly detection algorithm is used to further locate potential fault points, and the location results are provided to the enterprise side of the device together with the device operation and maintenance detection report. It should be noted that in this embodiment, it is specified that when the enterprise side of the device initiates a request, the detection module needs to be given extended detection permissions, so as to implement the principle of higher permissions on the enterprise side, that is, the fault log acquisition program can be initialized and more underlying logs can be retrieved, truly realizing comprehensive access to the core data of the device. Before obtaining the device operation and maintenance detection report, various log information such as the communication module log, hardware monitoring log, and system operation log are extracted and merged to form a multi-dimensional log data set. This approach can make the detection result not only depend on one-time detection, but also combine the historical and instant data of the device operation, making the diagnosis content more comprehensive and accurate. At the same time, by introducing the log aggregation and anomaly detection algorithm, the complex multi-dimensional log data can be aggregated and analyzed to automatically identify fault patterns or abnormal indicators. Compared with traditional manual troubleshooting, the algorithm can quickly and accurately discover potential hidden fault points, greatly improving the diagnosis efficiency. Finally, the potential fault points located by the log aggregation and anomaly detection algorithm are combined with the conventional device operation and maintenance detection report and provided to the enterprise side, so that the enterprise side can not only see the surface phenomena of faults or performance problems, but also see the deeper reasons or correlations, so as to be able to formulate maintenance strategies targeted.

[0037] In some further preferred embodiments, before the detection module performs fault and / or performance detection, the built-in self-check program is used to detect the functional integrity of the detection module itself; if the self-check result shows that the detection module is abnormal, a maintenance request is sent to the enterprise end of the device to avoid inaccurate detection results caused by the failure of the detection module; after the detection module is restored, the detection module is then controlled to perform the detection of the device operation and maintenance detection request or the detection of the device status detection request. It should be noted that before performing fault and / or performance detection, the self-check program is first used to check whether the detection module is working properly. If the detection module has abnormalities at the hardware or software level, the detection is suspended in a timely manner and reported to the enterprise end, which can avoid false or invalid detection results caused by the failure of the detection module. Only after the detection module is confirmed to be normal, the detection request initiated by the enterprise end or the user end is continued to be executed, so as to ensure that the final obtained detection result is traceable and credible. If the detection module performs detection without passing the self-check, misjudgment or even wrong judgment will occur, which will have an adverse impact on subsequent maintenance and user experience. By sending a maintenance request to the enterprise end and re-executing the detection after the detection module is restored, the self-fault of the detection module can be quickly located and repaired. It can be understood that compared with the traditional global fault troubleshooting, in this embodiment, the self-check is performed first on the key component of the detection module, which is beneficial to timely screen and repair the weak links in the detection link and reduce the interference with the overall device detection process. After the detection module is restored, the detection is performed again, and the detection results before and after are compared, which can quickly verify whether the fault has been truly eliminated, avoid repeated or unnecessary operation and maintenance processes, and make after-sales support and operation and maintenance more efficient.

[0038] In some further preferred embodiments, when a device operation and maintenance detection request initiated by the enterprise side of the device is received, the detection modules of multiple portable Wi-Fi devices are controlled to perform parallel detections simultaneously according to a preset batch detection strategy; cluster analysis is performed on multiple device operation and maintenance detection reports obtained from the parallel detections to screen out the portable Wi-Fi devices with failure rates and performance anomaly rates exceeding the thresholds; for the screened portable Wi-Fi devices, a priority maintenance list is automatically generated and fed back to the enterprise side of the device to achieve batch diagnosis and centralized maintenance. It should be noted that in this embodiment, by allowing multiple portable Wi-Fi devices to perform detections in parallel according to a preset batch detection strategy, the time cost for detecting hundreds or thousands of devices can be significantly reduced. Compared with sequential detection, the multi-threaded or parallel processing mode enables the enterprise side to collect the required operation and maintenance information faster. After obtaining the operation and maintenance detection reports of multiple devices, the cluster analysis method is used to aggregate and compare these reports to quickly identify the groups of devices with failure rates or performance anomaly rates exceeding the thresholds. This can not only detect the anomalies of single devices but also discover the common problems of certain batches, certain models or devices in the same operation area. After screening out the devices with failure rates and performance anomaly rates exceeding the thresholds and automatically generating a priority maintenance list, the enterprise side can conduct centralized inspections and quick repairs for potentially high-risk devices, which can avoid the blindness and resource waste caused by decentralized maintenance and also reduce the occurrence probability of major or batch failures. The centralized detection and unified analysis of multiple devices help the enterprise side summarize problems in the shortest time, reduce repeated operations and manual interventions; coupled with the accurate positioning of high-risk devices, it can greatly save the operation and maintenance manpower and material costs, and at the same time improve the operation and maintenance response speed and user satisfaction.

[0039] In some further preferred embodiments, when it is determined that the device detection request is a device status detection request initiated by the user terminal, the current geographical location information and network environment status of the corresponding portable Wi-Fi device are obtained from the detection module based on the detection permission of the user terminal; the geographical location information, the network environment status are associated and analyzed with the network signal quality reference data of the detection module to obtain a network signal stability evaluation result; when the network signal stability evaluation result is lower than a preset threshold, a preset network environment improvement suggestion is provided to the user terminal and the abnormal information when the network signal stability evaluation result is lower than the preset threshold is synchronized to the device enterprise terminal. It should be noted that the geographical location information and the network environment status (such as surrounding network signal interference, the number of available base stations, network coverage, etc.) are compared with the network signal quality reference data of the detection module, so as to obtain a more accurate network signal stability evaluation result. This means that the detection no longer relies solely on the data of the device itself, but can combine external conditions in the usage scenario to improve the reflection of the actual usage experience. When the network signal stability result is lower than the threshold, a preset network environment improvement suggestion can be actively provided to the user terminal, such as "change the location for use, change the operator network, upgrade the device firmware", etc. This can guide the user terminal to perform simple self-optimization, reduce the dependence on customer service, and improve the user experience and satisfaction. When the user is in a specific area or environment resulting in signal anomalies, the abnormal information will also be synchronized to the enterprise terminal, enabling the enterprise terminal to understand the performance of the portable Wi-Fi device in different geographical regions or network scenarios. This data is crucial for the enterprise terminal to make decisions such as network resource optimization, signal coverage planning, and device hardware upgrade, and is conducive to the enterprise terminal to carry out optimization at the macro level. In addition, through the detection results of the geographical location and network environment, the user terminal can obtain more targeted usage tips; the enterprise terminal can improve at the overall service or network deployment level with the help of the centralized backhaul of abnormal information, realizing a two-way positive interaction and enhancing the overall operation ability of the portable Wi-Fi device.

[0040] In some further preferred embodiments, after detecting faults and / or performance, the control detection module records the obtained key parameters to the cloud database; the key parameters include network speed, CPU occupancy rate, and traffic status; when receiving the device operation and maintenance detection request from the device enterprise end again later, the historical key parameters of the corresponding portable WIFI device in the cloud database are automatically obtained for vertical comparison to generate a long-term performance monitoring trend; if the long-term performance monitoring trend shows abnormal fluctuations or signs of degradation, the device enterprise end is notified to conduct key troubleshooting and remote maintenance on the corresponding portable WIFI device. It should be noted that saving core performance indicators such as network speed, CPU occupancy rate, and traffic status in the cloud database can achieve continuous accumulation of detection data for portable WIFI devices, facilitating comparison and analysis by the enterprise end and the user end in the future, rather than being limited to the current detection result. The enterprise end can automatically obtain the detection parameters of the same device at different times for vertical comparison, so as to discover the change trend of the device performance over time or usage conditions, providing a more scientific decision-making basis for maintenance and upgrade. If the vertical analysis shows abnormal fluctuations or degradation trends in the device performance, automatically notifying the enterprise end for key troubleshooting and remote maintenance can intervene in a timely manner before or at the early stage of a fault, reducing the incidence of serious faults and improving service quality and user satisfaction. For an enterprise end with a large number of portable WIFI devices, the cloud database can integrate the historical key parameters of all devices to comprehensively evaluate the health status of each device, which is conducive to quickly screening out the devices that need centralized maintenance and further improving the batch operation and maintenance efficiency.

[0041] In some further preferred embodiments, after the detection is completed, according to the type of the device detection request, an archiving instruction is sent to the detection module to archive and package the fault information and performance data during the detection process; the archived and packaged fault information and performance data are stored in the secure storage area of the portable Wi-Fi device in an encrypted form and a corresponding index is generated; when a detection request initiated by the user terminal or the device enterprise terminal is received again, the corresponding historical records are quickly located and called by using the index to assist the detection module to accelerate the subsequent detection process and improve the accuracy of fault diagnosis. It should be noted that in this embodiment, by storing the fault information and performance data in the secure storage area of the portable Wi-Fi device in an encrypted form and generating a corresponding index, while ensuring the confidentiality of the data, the management of a large amount of detection data can be structured and retrievable. It not only avoids the difficulty of traceability caused by scattered data, but also significantly improves the efficiency of subsequent access. When a detection request from the user terminal or the enterprise terminal is received again, the corresponding historical fault information and performance data can be quickly found through the index, eliminating the process of repeated collection or processing. By comparing the detection results at different time points, the fault evolution trend or the problems that have occurred can be quickly identified, significantly improving the diagnostic accuracy and processing efficiency. Based on the existing historical records, the detection module can quickly match and preferentially identify the same or similar faults based on the past diagnostic results and performance data. This can not only reduce the burden of repeated detection, but also discover potential fault patterns at an early stage, making the subsequent detection more targeted and accurate. In addition, by archiving and encrypting the data generated by each detection, a detection file of the device during its entire life cycle of use can be formed. This helps to provide a complete detection history during the after-sales process, which has important reference value for the in-depth traceability of device faults, batch problem troubleshooting, and continuous performance optimization, and can further reduce the enterprise's operation and maintenance and quality inspection costs.
