Description

Technical Field

[0001] This invention relates to the field of intelligent inspection technology, and in particular to an inspection trajectory positioning and analysis system based on a mobile terminal. Background Technology

[0002] Ensuring the safety of workers is paramount in the daily operation of the power plant. However, due to the numerous and widespread potential hazards, comprehensive and ongoing monitoring is difficult. Furthermore, many of the company's power plants are located in desert areas or complex environments, requiring reliable protection for the personal safety of frontline workers. This is especially true given the limitations of precise personnel tracking, incident prevention and retrospective analysis, the lack of early warning capabilities for abnormal personnel movements, and the significant challenges in recording and tracing safety incidents.

[0003] Currently, traditional paper-based records are still used in inspection work. These records are often time-consuming and labor-intensive, and the inspection trajectories may not be accurate. The recorded information is also difficult to analyze digitally. While using mobile apps combined with QR codes to record inspection work reduces the workload to some extent, the veracity of inspection trajectories is often uncertain due to the copyability of QR codes. Furthermore, the electronic fences used by the mobile apps need to be combined with the procurement map, and trajectories outside the map's boundaries cannot be confirmed.

[0004] Therefore, it is necessary to propose an inspection trajectory positioning and analysis system based on mobile terminals. Summary of the Invention

[0005] This invention provides a mobile terminal-based inspection trajectory positioning and analysis system. By using mobile terminals for inspection trajectory positioning, convenient, accurate and rapid positioning can be achieved, which can not only verify the work location of staff, but also ensure the safety of staff during inspection work.

[0006] This invention provides a mobile terminal-based inspection trajectory positioning and analysis system, comprising:

[0007] The inspection trajectory positioning module is used to display the inspection trajectory positioning of the inspection personnel based on the mobile terminal device with integrated positioning module carried by the inspection personnel and using the geographic information system map.

[0008] The electronic fence early warning module is used to draw electronic fences on the overlay layer of the geographic information system map and use the electronic fences to monitor the inspection trajectory of the inspection personnel.

[0009] The inspection record generation module is used to collect audio and video data of the inspection site through the audio and video device on the mobile terminal device and send it to the electronic work order management unit of the monitoring platform. The electronic work order management unit is used to realize the generation, archiving and traceability of inspection records.

[0010] The inspection record query module is used to store, query, and verify the inspection records of inspection personnel using the smart IoT cloud platform.

[0011] Furthermore, the inspection trajectory positioning module includes a mobile terminal device data acquisition and setting unit and a data acquisition conversion unit;

[0012] The mobile terminal device data acquisition and setting unit is used to set acquisition parameters and use these parameters to acquire the location data of the inspection personnel's inspection trajectory, thereby obtaining the first acquisition data. The acquisition parameters include acquisition frequency, acquisition accuracy, and acquisition program.

[0013] The data acquisition and conversion unit is used to receive the first acquired data based on the wireless communication network; based on the geographic information system map, it converts the latitude and longitude coordinate data of the earth in the first acquired data into geographic information system map coordinate data, and then generates the inspection trajectory location of the inspection personnel through dense point trajectory drawing and trajectory smoothing optimization algorithm.

[0014] Furthermore, the electronic fence early warning module includes:

[0015] Using planar geometric image drawing algorithms, electronic fences are drawn on the overlay layers of geographic information system maps;

[0016] Match and bind the fence area of ​​the electronic fence with the boundary area of ​​the inspection personnel's inspection trajectory, and set the early warning conditions of the electronic fence.

[0017] If the inspection personnel's inspection trajectory exceeds the boundary area of ​​the inspection trajectory, the electronic fence's early warning condition is triggered, and the electronic fence issues an early warning reminder.

[0018] Furthermore, the electronic fence early warning module also includes an electronic fence early warning condition correction unit, used to correct the early warning conditions of the electronic fence to ensure that the electronic fence issues early warning reminders reasonably and accurately; the electronic fence early warning condition correction unit includes:

[0019] According to the preset first warning condition, the entire inspection process of the inspection personnel is tested, and the test warning reminder data issued by the electronic fence is obtained; based on the test warning reminder data, the duration and distance data of the inspection personnel's inspection trajectory exceeding the boundary area of ​​the inspection trajectory are obtained; based on the duration and distance data of the exceeding, the warning sensitivity of the first warning condition is calculated.

[0020] Based on the historical location data of the inspection personnel's inspection trajectory, an inspection early warning sensitivity threshold is set. If the early warning sensitivity is greater than the inspection early warning sensitivity threshold, the early warning sensitivity of the first early warning condition is reduced by a preset adjustment range, and the first early warning condition is corrected accordingly. If the early warning sensitivity is less than the inspection early warning sensitivity threshold, the early warning sensitivity of the first early warning condition is increased by a preset adjustment range, and the first early warning condition is corrected accordingly.

[0021] Furthermore, the inspection record generation module includes:

[0022] Configure the audio and video capture method on the mobile terminal device;

[0029] Based on historical inspection records, extract several feature attribute values ​​from the historical inspection records, and generate an inspection record verification template based on the feature attribute values;

[0030] Obtain the inspection record to be verified, extract the feature attribute values ​​of the inspection record to be verified, use the inspection record verification template to perform the first verification of the inspection record to be verified, and obtain the first verification result.

[0031] If the first verification result is abnormal, obtain the feature attribute item that matches the abnormality based on the first verification result;

[0032] Based on the preset credibility judgment conditions, the credibility of the matched abnormal feature attribute items is determined. If the credibility is less than the preset credibility threshold, the first verification result is ignored as abnormal; if the credibility is greater than the preset credibility threshold, the first verification result is confirmed as abnormal. The credibility judgment conditions are set according to the importance of the feature attribute items to the inspection record and the probability of errors in the feature attribute items.

[0033] Furthermore, the inspection record monitoring module also includes an inspection work assessment unit, used to assess the inspection work of inspection personnel; the inspection work assessment unit includes:

[0034] Set up fixed segmented inspection routes for inspection staff and set a specified inspection time range for several inspection points;

If the deviation value is greater than the preset deviation value threshold and the duration of the deviation value is greater than the preset duration period, then generate the first work assessment violation item.

[0036] The system obtains the real-time inspection time of the inspection points of the inspection staff. If the real-time inspection time is less than the lower limit of the preset inspection time range, a second work assessment violation is generated. If the real-time inspection time is greater than the upper limit of the preset inspection time without the time spent on fault repair, a third work assessment violation is generated.

[0037] Based on the first, second, and third violations of the work assessment, and combined with the analysis results of the audio and video data, the inspection staff were assessed.
