[0021] An influencing factor acquisition module is used to obtain the construction project personnel influencing factors of the first safety reference value using the personnel influencing formula based on the consulting and purchasing data of the construction project; The formula for personnel impact is: ; Where, The factors affecting construction workers are the first safety reference value; For construction areas and The maximum impact separation distance of the residence of construction workers; For construction areas and The actual distance between the residences of construction workers; For the The average value of the historical purchasing capacity of each construction engineer; Purchase capacity value for the actual needs of construction projects; It is the weight adjustment value of the first safety reference value.

If it is not within the reasonable range, an exception is thrown and a log is recorded for subsequent manual intervention; if If the risk is lower than the preset safety threshold, the project will be automatically marked as high risk; If it is higher than the preset safety threshold, it will flow normally.

[0028] It should be further explained that the schedule adjustment module calls the project management system interface to obtain the execution time (earliest start, latest start and duration) and the preceding and following relationship data of all activities to form an activity list; based on the obtained execution time and the correlation relationship, a directed acyclic graph (AOE network) is constructed in the memory to calculate the earliest and latest occurrence time of each activity, and identify key activities and non-key activities; the latest calculated first safety reference value and second safety reference value are read from the first safety value acquisition module and the second safety value acquisition module respectively, and for each non-key activity, the first safety reference value and the second safety reference value are read from the first safety value acquisition module and the second safety value acquisition module respectively. Moderately postpone or start in advance within the preset range; if and If high, non-critical activities are allowed to execute close to the latest start time to save resources; if and If the load is low, start early to increase the safety buffer.
[0029] Obtain the earliest and latest start times of each non-critical activity in the construction project. Use the start time adjustment formula based on the first safety reference value and the second safety reference value to adjust the occurrence events of the non-critical activities, obtain the final start time of the non-critical activities, and plan and arrange activities based on the final start time of each non-critical activity. The final start time of the non-critical activity is greater than the earliest start time. The start time adjustment formula is: ; Where, The final activity start time for non-critical activities; The latest activity start time for non-critical activities; is the adjustment coefficient; It is the first safety reference value for construction projects; It is the second safety reference value for construction projects.
[0030] The risk adjustment management module is used to manage the risks of key activities and non-key activities according to the first safety reference value and the second safety reference value.
[0031] When the second safety reference value is lower than the preset safety threshold, the emergency plan for key activities is triggered; when the second safety reference value is higher than the preset safety threshold, the safety assessment of the construction project is carried out in combination with the first safety reference value; and the construction project resources are optimized according to the first safety reference value.
[0032] It should be further explained that, based on historical experience, the administrator sets a preset safety threshold in the configuration file as the dividing line between high and low risks. When the second safety reference value is lower than the preset safety threshold, it is judged to be a high-risk state; when the second safety reference value is higher than the preset safety threshold, it is judged to be a low-risk or normal state; if it is judged to be a high-risk state, the module automatically starts the emergency plan sub-module for key activities, issues safety reinforcement and dedicated monitoring instructions for all key activities; dispatches emergency resources to key processes on site; records event trigger logs, notifies the project leader and generates a plan report; if it is judged to be a low-risk state, the module conducts an in-depth safety assessment in combination with the first safety reference value; and optimizes construction project resources based on the first safety reference value.
