Each group of index value ranges is set to correspond to a risk level. The risk levels include general risk, medium risk and serious risk.

[0030] Match the grade assessment index calculated by the current triggering environmental warning signal with the preset three groups of index value ranges to obtain the risk level at the current construction start time;

[0031] If the risk level is general risk, firstly, an environmental abnormality signal is sent to the mobile terminal of the construction personnel to remind them that the current tunnel environment is abnormal and they should wear protective equipment, but no emergency measures are needed. The sensors deployed in the tunnel environment continuously collect and monitor the tunnel environment parameters during the construction process, send an adjustment signal to the mobile terminal of the manager, and establish a communication connection between the ventilation equipment in the tunnel environment and the mobile terminal of the manager. The manager can remotely adjust the ventilation equipment parameters deployed in the tunnel environment through the mobile terminal.

An inspection signal is also sent to the mobile terminals of the management personnel to inform the inspectors that a detailed inspection of the tunnel construction area will be carried out.

[0033] If the risk level is severe, a construction suspension signal is first sent to the mobile terminals of the construction workers to remind them to suspend construction activities completely, adjust the collection time interval of the sensors deployed in the tunnel environment, and continue monitoring until the tunnel environment conditions are controlled and improved.

[0037] If the impact level is slight, record the current construction impact assessment index. The alarm installed in the tunnel environment is triggered and the sound frequency set for the minor impact level is played to remind the construction personnel to reduce the subsequent construction speed and reduce the impact on the environment and personnel. After the construction is completed on the same day, the construction method is reviewed and whether measures need to be taken to mitigate the impact of subsequent construction;

[0038] If the impact level is a major impact level, the construction impact parameters in the subsequent construction process are monitored and analyzed on the basis of the minor impact level. If the construction impact parameters in the subsequent construction process still trigger the construction early warning signal, the corresponding steps of the severe impact level are executed;

[0039] If the impact level obtained is a severe impact level, the alarm installed in the tunnel environment will be triggered, and the sound frequency set for the severe impact level will be played, the remaining construction progress for the day will be suspended, and a maintenance signal will be sent to the manager's mobile terminal. After receiving the maintenance signal, the manager can search for maintenance personnel around the current tunnel construction environment with one click. The manager selects a suitable maintenance personnel and sends a search signal to the personnel's mobile terminal. After arriving at the tunnel construction environment, the personnel will check the construction equipment and determine the cause of the abnormality.

[0040] In some embodiments, one-click retrieval of maintenance personnel around the current tunnel construction environment is as follows:

[0041] With the current tunnel construction location as the center and the set distance as the radius, draw a circle, screen the maintenance personnel within the circle, and obtain the distance between them and the tunnel construction location. The person with the shortest distance is taken as the fastest arriving person, and further obtain the working hours and number of inspections of each maintenance personnel within the circle. The person with the longest working hours is taken as the longest staff member, and the person with the highest number of inspections is taken as the most experienced person. The fastest arriving person, the longest staff member, and the most experienced person are pushed to the mobile terminal of the manager, and then selected through the mobile terminal.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] The present invention sets a continuous period for collecting tunnel environmental parameters and analyzes the tunnel environmental parameters before the start time of each day of the construction period, thereby obtaining an environmental safety assessment index before the start time of each day of the construction period. According to the obtained environmental safety assessment index, potential safety risks can be effectively prevented, and environmental early warning signals can be triggered in time, thereby improving the efficiency and accuracy of construction safety management.

[0044] The present invention obtains a construction impact assessment index by analyzing the influencing parameters of construction noise and abnormal vibration, and triggers a construction early warning signal through a preset reference threshold index, thereby realizing real-time monitoring and timely response of the construction process, thereby avoiding adverse effects on the surrounding environment of the construction, and also ensuring the safety of construction personnel.

The complex data is converted into intuitive images by drawing a rectangular model. A quantitative environmental safety assessment index is provided by calculating the area value of the abnormal assessment model, which provides a quantitative basis for construction safety management.

[0068] The construction assessment module is used to analyze the construction impact parameters of the set duration after the construction start time point on each day of the construction cycle, thereby obtaining the construction impact assessment index of the set duration after the construction start time point on each day of the construction cycle. ; Preset construction impact assessment index for each day The reference threshold index is recorded as ; Technical personnel set dynamically changing reference threshold indexes based on relevant data such as geological conditions, construction methods, regional standards, and sensitivity of the surrounding environment, and adjust the reference threshold indexes when the corresponding date is reached; if the display result after the construction start time on a certain day during the construction period is > , then the construction early warning signal is triggered;

[0073] The environmental warning module is used to receive the triggered environmental warning signal and execute corresponding steps; specifically:

[0074] Extract the environmental safety assessment index corresponding to the triggering environmental warning signal , and calculate the corresponding reference threshold index The calculated difference is used as the grade evaluation index, and three groups of index value ranges of the grade evaluation index are preset. Each group of index value ranges is set to correspond to a risk level. The risk levels include general risk, medium risk and serious risk.

[0075] The grade evaluation index calculated by the current triggering environmental warning signal is matched with the preset three groups of index value ranges to obtain the risk level at the current construction start time; the larger the grade evaluation index, the higher the matched risk level;

[0076] If the risk level is general risk, firstly, an environmental abnormality signal is sent to the mobile terminal of the construction personnel to remind them that the current tunnel environment is abnormal and they should wear protective equipment, but no emergency measures are needed. The sensors deployed in the tunnel environment continuously collect and monitor the tunnel environment parameters during the construction process, send an adjustment signal to the mobile terminal of the manager, and establish a communication connection between the ventilation equipment in the tunnel environment and the mobile terminal of the manager. The manager can remotely adjust the ventilation equipment parameters deployed in the tunnel environment through the mobile terminal.

[0077] If the risk level is medium, an environmental hazard signal is first sent to the mobile terminals of the construction personnel to remind them that the current tunnel environment is abnormal and construction is suspended. An inspection signal is also sent to the mobile terminals of the management personnel to inform the inspectors that a detailed inspection of the tunnel construction area will be carried out and corresponding measures will be taken according to the inspection results.

[0078] If the inspection result shows that construction is possible, the corresponding steps for general risks will be carried out. If the inspection result shows that construction is suspended, the sensors deployed in the tunnel environment will continuously collect and monitor the tunnel environment parameters during the construction process.

[0079] If the risk level is severe, a construction suspension signal is first sent to the mobile terminals of the construction workers to remind them to suspend all construction activities, adjust the collection time interval of the sensors deployed in the tunnel environment, and continue monitoring until the tunnel environment conditions are controlled and improved;

[0080] The construction management module is used to receive the triggered construction warning signal and execute the corresponding steps; specifically:

Each group of index value ranges is set to correspond to an impact level, and the impact levels include slight impact, major impact and severe impact;

[0082] The impact assessment index calculated by the current triggering construction warning signal is matched with the preset three groups of index value ranges to obtain the impact level at the current construction start time point;

[0083] If the impact level is slight, record the current construction impact assessment index. The alarm installed in the tunnel environment is triggered and the sound frequency set for the minor impact level is played to remind the construction personnel to reduce the subsequent construction speed and reduce the impact on the environment and personnel. After the construction is completed on the same day, the construction method is reviewed and whether measures need to be taken to mitigate the impact of subsequent construction;

[0084] If the impact level is a major impact level, the construction impact parameters in the subsequent construction process are monitored and analyzed on the basis of the minor impact level. If the construction impact parameters in the subsequent construction process still trigger the construction early warning signal, the corresponding steps of the severe impact level are executed;

[0085] If the impact level is a severe impact level, the alarm installed in the tunnel environment is triggered and the sound frequency set for the severe impact level is played. The remaining construction progress for the day is suspended and a maintenance signal is sent to the mobile terminal of the manager. After receiving the maintenance signal, the manager searches for maintenance personnel around the current tunnel construction environment with one click. The manager selects a suitable maintenance personnel and sends a search signal to the mobile terminal of the personnel. After the personnel arrives at the tunnel construction environment, they check the construction equipment and determine the cause of the abnormality.

[0086] The specific process of one-key retrieval is as follows:

[0087] Draw a circle with the current tunnel construction location as the center and the distance as the radius, screen the maintenance personnel within the circle, and obtain the distance between them and the tunnel construction location. The person with the shortest distance is regarded as the fastest arriving person. Further obtain the working hours and number of inspections of each maintenance personnel within the circle, and regard the person with the longest working hours as the longest staff member, and the person with the highest number of inspections as the most experienced person. The fastest arriving person, the longest staff member, and the most experienced person are pushed to the mobile terminal of the manager, and then selected through the mobile terminal;

[0088] The construction management module is also provided with a dynamic adjustment unit, which is used to send a completion assessment signal to the mobile terminal of the manager one day before the construction period and execute corresponding steps;

[0089] Specifically:

[0090] After receiving the completion assessment signal, the manager will assess the progress of the current municipal tunnel project and provide feedback on the assessment results. If the feedback assessment result is a delay in completion, the estimated number of days for delayed completion will be pushed to fill in the interface. After the manager completes the filling, a construction analysis signal is sent to the manager's mobile terminal. After the manager confirms the construction analysis signal, the monitoring video of the surrounding environment of the current municipal tunnel project is extracted. The monitoring video is a driving video of the surrounding roads.

[0091] Fill in the results based on the estimated days of the managers, and match the filled-in estimated days from Monday to Sunday to obtain the construction dates for each future day;

[0092] If the first day of the estimated days is Tuesday, the driving video of Tuesday seven days in advance is divided into X sub-periods according to the preset division period, X>5, and the specific division period is set by the technical personnel; the traffic flow in the driving video of each sub-period is obtained, and the traffic flow of the corresponding sub-period in the past seven days is averaged to obtain the traffic flow estimation of the sub-period; based on the size of the traffic estimation, the divided sub-periods are sorted, the smaller the traffic estimation, the higher the ranking, and the top three sub-periods are selected as the preferred construction period for the first day of the estimated days, and pushed; similarly, the remaining dates of the estimated days are analyzed accordingly, and integrated into a delayed completion period optimization table and sent to the mobile terminal of the management personnel;

[0093] Through the analysis and sorting of traffic flow, it helps managers select the optimal construction period, improves construction efficiency, and reduces construction interruptions caused by traffic interference;

[0094] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The influencing weight factor and specific coefficient value in the formula are set by technical personnel in this field according to actual conditions, and can be adjusted and modified later.
