Description

Technical Field

[0001] This invention relates to the field of construction safety supervision and early warning technology, and in particular to a dynamic safety path planning and early warning system for related work processes and tasks. Background Technology

[0002] Construction sites present complex environments with numerous safety risks, including deep foundation pits, high-altitude work platforms, and heavy equipment storage areas. Current safety management at construction sites primarily focuses on the working phase, ensuring safety through measures such as wearing safety helmets, setting up warning signs, and conducting pre-shift safety briefings. However, significant loopholes exist in safety management during non-working phases, such as commuting, lunch breaks, nighttime rest, and periods of free movement on the site.

[0003] Workers' activities outside of work hours are characterized by high randomness, separation from team management, and lax safety awareness, making them prone to entering unprotected risk areas, approaching dangerous equipment, and using open flames in violation of regulations, which can lead to safety accidents such as falls, collisions, and fires. Existing management methods rely heavily on manual patrols, which have problems such as patrol blind spots, delayed response, and lack of real-time early warning, making it difficult to achieve comprehensive and dynamic safety control of workers outside of work hours.

[0004] Therefore, the present invention provides a dynamic safety path planning and early warning system for related process tasks. Summary of the Invention

[0005] This invention provides a dynamic safety path planning and early warning system for associated work processes and tasks, which aims to improve the overall safety management level of construction sites by enabling real-time monitoring, risk identification, and proactive early warning of workers' non-working activities.

[0006] This invention provides a dynamic safety path planning and early warning system for associated process tasks, comprising: The work assignment module is used to assign corresponding construction work to each worker according to the on-site tasks at the construction site, and at the same time determine the start and end times of each worker. The on-site analysis module is used to obtain the current construction data of each on-site worker to restore the construction progress of the construction site and analyze several current dangerous areas in the construction site. The path planning module is used to formulate a safe route to work for each worker and a safe route home for each worker based on the current time and the distribution of the current hazardous area. The hazard warning module is used to verify the worker's clothing and behavioral characteristics and provide corresponding hazard warnings when the worker enters the current hazard area.

[0007] In one feasible approach Also includes: The trajectory tracking module is used to deduce the working time period and the off-work time period of each worker based on their working time and off-work time. The behavior of the workers is tracked during the time periods when they go to work and when they leave work by using on-site monitoring, so as to obtain the workers' trajectories when they go to work and when they leave work. The worker's safety awareness characteristics are generated based on the first trajectory overlap rate between the worker's going-to-work trajectory and the corresponding safe going-to-get off work path, and the second trajectory overlap rate between the worker's leaving-to-work trajectory and the corresponding safe leaving-to-work path. If the safety awareness characteristics are not met, the worker's construction work shall be adjusted.

[0008] In one feasible approach The process allocation module includes: The worker management unit is used to construct the job layout of the construction site based on the worker entry information corresponding to each worker, determine several types of executable work for each worker at the construction site, and determine the worker's proficiency in performing each type of executable work. The process allocation unit is used to decompose the on-site execution tasks of the construction site into several construction processes, simulate the construction process corresponding to each construction process, and allocate the corresponding construction process to each worker based on the executable work and execution proficiency of each worker. The time allocation unit is used to deduce the construction time period corresponding to each assigned worker in the construction process according to the preset work start and end standards, and to uniformly adjust the construction time period according to the time difference between the construction time periods corresponding to each assigned worker, and generate shift change information corresponding to each type of work in the construction process. The worker notification unit is used to determine the start and end times of each worker based on the shift change information, generate a corresponding shift report, and transmit it to the terminal of each worker for display.

[0009] In one feasible approach The on-site analysis module includes: The data acquisition unit is used to track the work process of each worker at the construction site when construction begins, analyze the corresponding work actions of each worker at different times, and obtain the current construction data of each worker. The progress derivation unit is used to synchronously construct the completed construction at the construction site based on the current construction data, construct the acceptance conditions corresponding to each completed construction using the on-site execution tasks, and use the acceptance conditions to perform acceptance evaluation on the corresponding completed construction to obtain the on-site quality corresponding to each completed construction. The hazard analysis unit is used to determine the degree of hazard and the scope of hazard corresponding to the completed construction based on the site quality, divide the construction site into areas based on the degree of hazard, and determine several current hazard areas of the construction site.

[0010] In one feasible approach The path planning module includes: The status classification unit is used to analyze the list of workers on duty and workers off duty at the construction site within a specified time period based on the start and end times of each worker and the current time, and to determine the current construction location and accommodation location of each worker on duty / off duty. The work planning unit is used to obtain several historical work paths corresponding to each worker, extract relevant path segments from each historical work path according to the corresponding current construction position, and reorganize the relevant path segments according to the distance relationship between each relevant path segment and different current danger areas to obtain a safe work path for each worker. The off-duty prediction unit is used to deduce the off-duty construction position of each off-duty worker at the off-duty time based on the construction work corresponding to each off-duty worker, and at the same time, to deduce the hazard characteristics of each current hazard area at the off-duty time based on the construction progress. The off-get off work planning unit is used to construct an initial off-get off work route based on the off-work work location and accommodation location of each worker, select the safe commuting route with the highest similarity to the initial off-get off work route at the current time, and optimize the safe commuting route using the hazard features to obtain the safe off-get off work route for the worker.

[0011] In one feasible approach Also includes: Calculate the safe commute route and safe commute route for each time point; Based on the building distribution at the construction site, the safe commuting route and the safe commuting route are divided into several safe route segments; The safety path information of the construction site is constructed and displayed based on the safety path segment.

[0012] In one feasible approach The danger warning module includes: The on-work / off-work tracking unit is used to acquire the real-time on-work / off-work path of the worker when the worker goes to work / off work, and analyze whether the worker has entered the current danger zone based on the real-time on-work / off-work path; The area analysis unit is used to obtain the area presentation characteristics corresponding to the current hazardous area, and generate safe behavior conditions for entering the current hazardous area in combination with the hazard prevention measures at the construction site. A safety evaluation unit is used to acquire the worker's clothing and behavioral characteristics in the current hazardous area, and to evaluate each clothing and behavioral characteristic using the safety behavior conditions. The alert and warning unit is used to remind the worker when the worker's clothing exhibits dangerous characteristics, and to issue an early warning when the worker exhibits dangerous behavioral characteristics.

[0013] In one feasible approach Also includes: A hazard handling unit is used to construct the hazard impact range based on the hazard level and hazard range corresponding to the current hazard area when the worker is injured in the current hazard area. Analyze the worker's injury location and severity, and generate an emergency response plan based on the scope of the current danger, then guide each relevant person to respond to the emergency response plan.

[0014] In one feasible approach Also includes: The deep monitoring module is used to obtain the list of workers leaving work at the current time, construct the safe free movement range for each worker by combining the safe path information, and transmit it to the terminal of each worker for display.

[0015] In one feasible approach The process of optimizing the safe commuting route based on the aforementioned hazardous characteristics to obtain the safe commuting route for the workers includes: Adjust the original starting point and original ending point of the safe commute route based on the starting point and ending point of the initial commute route to obtain the mid-to-commute route; Based on the hazardous features, the actual distribution of hazards at the construction site is plotted, and the middle and late shift paths corresponding to each worker are marked in the actual distribution of hazards. The first positional relationship between each middle and late shift path and the hazardous features is obtained, as well as the second positional relationship between different middle and late shift paths. Based on the first positional relationship, the middle and end-of-shift routes are adjusted for the first time to obtain the final end-of-shift route for each worker. Based on the second positional relationship analysis, the worker congestion rate corresponding to each site road in the construction site at the time of the end of the workday; The final departure route is adjusted a second time based on the worker congestion rate to obtain several alternative departure routes. The final departure route and detour departure route for each worker are counted separately to construct several safe departure routes for the workers.

[0016] The beneficial effects achievable by this invention are as follows: To manage construction from the dimensions of safety control, efficiency improvement, and risk prediction, the invention first clarifies the start and end times of workers' shifts, avoiding time conflicts when workers from different work processes overlap. This also provides a time basis for subsequent route planning, deeply integrating safety management with construction procedures rather than managing them in isolation. Then, for each worker's specific construction task, start and end times, relevant safety routes are developed. This avoids dangers for workers on their commutes and facilitates worker evacuation, preventing congestion and ensuring a balance between safety and operational convenience, thereby increasing worker motivation. Furthermore, progress is dynamically reconstructed through construction data. It simultaneously identifies current hazardous areas, avoiding omissions due to reliance on static risk maps, ensuring the timeliness and comprehensiveness of risk identification. Finally, by combining the current time and the distribution of hazardous areas, it adjusts workers' commuting routes in real time, reducing the probability of workers accidentally entering hazardous areas from the source. Compared with fixed route planning, it is more adaptable to the dynamic changes of the construction site. At the same time, it conducts double verification of workers entering hazardous areas, ensuring that workers not only know the dangers but also reduce risks by standardizing their clothing and correcting their behavior. It eliminates the need for manual patrols and inspections, significantly shortening the time lag for risk intervention. It is especially suitable for scenarios with complex construction site environments and dynamically changing hazardous areas, reducing the probability of safety accidents.

[0017] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0018] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used together with the embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings: Figure 1This is a schematic diagram of the composition of a dynamic safety path planning and early warning system for associated process tasks in an embodiment of the present invention; Figure 2 This is a schematic diagram of the composition of the process allocation module in a dynamic safe path planning and early warning system for associated process tasks according to an embodiment of the present invention. Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1: This example provides a dynamic safety path planning and early warning system for associated process tasks, such as... Figure 1 As shown, it includes: The work assignment module is used to assign corresponding construction work to each worker according to the on-site tasks at the construction site, and at the same time determine the start and end times of each worker. The on-site analysis module is used to obtain the current construction data of each on-site worker to restore the construction progress of the construction site and analyze several current dangerous areas in the construction site. The path planning module is used to formulate a safe route to work for each worker and a safe route home for each worker based on the current time and the distribution of the current hazardous area. The hazard warning module is used to verify the worker's clothing and behavioral characteristics and provide corresponding hazard warnings when the worker enters the current hazard area.

[0022] In this example, the construction site refers to the area where construction is about to take place; In this example, "on-site task execution" refers to the tasks that need to be completed at the construction site. In this example, the start time refers to the moment when a worker begins work, and the end time refers to the moment when a worker stops work, and the total working hours for each worker per day do not exceed 8 hours. In this example, the current danger zone refers to the dangerous area in the construction site at the current moment; In this example, a safe commute route means that workers have the highest safety factor when following this route to work, and a safe commuting route means that workers have the highest safety factor when following this route to leave work. In this example, clothing characteristics refer to the features of the worker's clothing and hats, such as whether they are wearing safety helmets and reflective vests, while behavioral characteristics refer to the features of the worker's activities at the construction site, such as whether they illegally cross warning lines or operate in a non-standard manner.

[0023] The working principle and beneficial effects of the above technical solution are as follows: To manage from the dimensions of construction safety control, efficiency improvement, and risk prediction, the first step is to clearly define the start and end times of workers to avoid time conflicts when workers in different work processes overlap. This also provides a time basis for subsequent route planning, deeply integrating safety management with construction processes rather than controlling them in isolation. Then, for each worker's specific construction task, start and end times, relevant safety routes are developed. This avoids dangers for workers on their commutes and facilitates worker evacuation, preventing congestion and ensuring a balance between safety and operational convenience. This enhances worker motivation and further allows for dynamic reconstruction through construction data. The system synchronously identifies current hazardous areas, avoiding omissions due to reliance on static risk maps and ensuring the timeliness and comprehensiveness of risk identification. Finally, by combining the current time and the distribution of hazardous areas, it adjusts workers' commuting routes in real time, reducing the probability of workers accidentally entering hazardous areas from the source. Compared with fixed route planning, it is more adaptable to the dynamic changes of the construction site. At the same time, it conducts double verification of workers entering hazardous areas, ensuring that workers not only know the dangers but also reduce risks by standardizing their clothing and correcting their behavior. It eliminates the need for manual patrols and inspections, significantly shortening the time lag for risk intervention. It is especially suitable for scenarios with complex construction site environments and dynamically changing hazardous areas, reducing the probability of safety accidents.

[0024] Example 2: Based on Example 1, the dynamic safety path planning and early warning system for associated process tasks further includes: The trajectory tracking module is used to deduce the working time period and the off-work time period of each worker based on their working time and off-work time. The behavior of the workers is tracked during the time periods when they go to work and when they leave work by using on-site monitoring, so as to obtain the workers' trajectories when they go to work and when they leave work. The worker's safety awareness characteristics are generated based on the first trajectory overlap rate between the worker's going-to-work trajectory and the corresponding safe going-to-get off work path, and the second trajectory overlap rate between the worker's leaving-to-work trajectory and the corresponding safe leaving-to-work path. If the safety awareness characteristics are not met, the worker's construction work shall be adjusted.

[0025] The working principle and beneficial effects of the above technical solution: the time period for going to work refers to the time period during which a worker walks from his / her residence to his / her work position, and the time period for going off work refers to the time period during which a worker walks from his / her work position to his / her residence. In this example, the "starting work trajectory" represents the path a worker takes during the starting work process, and the "ending work trajectory" represents the path a worker takes during the ending work process. The working principle and beneficial effects of the above technical solution are as follows: By tracking the going-to-work and going-out-of-work trajectories of each worker, it can be determined whether they are walking in the prescribed safe path. If they have not been walking in the safe path for a long time, their construction work will be adjusted, which indirectly motivates all workers to establish a safety awareness.

[0026] Example 3: Based on Example 1, the dynamic safety path planning and early warning system for associated process tasks, wherein the process allocation module, as shown in Example 1... Figure 2 As shown, it includes: The worker management unit is used to construct the job layout of the construction site based on the worker entry information corresponding to each worker, determine several types of executable work for each worker at the construction site, and determine the worker's proficiency in performing each type of executable work. The process allocation unit is used to decompose the on-site execution tasks of the construction site into several construction processes, simulate the construction process corresponding to each construction process, and allocate the corresponding construction process to each worker based on the executable work and execution proficiency of each worker. The time allocation unit is used to deduce the construction time period corresponding to each assigned worker in the construction process according to the preset work start and end standards, and to uniformly adjust the construction time period according to the time difference between the construction time periods corresponding to each assigned worker, and generate shift change information corresponding to each type of work in the construction process. The worker notification unit is used to determine the start and end times of each worker based on the shift change information, generate a corresponding shift report, and transmit it to the terminal of each worker for display.

[0027] In this example, the job layout refers to the result of statistical analysis of the job types of the workers who have already completed their onboarding. In this example, an executable job refers to a job that a worker can complete on the construction site; In this example, execution proficiency refers to the worker's proficiency in performing a task; In this example, shift change information refers to information about worker shift changes within a unified time period; In this example, the scheduling report intuitively displays core information, eliminating the need for workers to repeatedly ask managers, and for managers to notify each worker individually, thus reducing communication time and errors. This is especially suitable for construction sites with a large number of workers and frequent changes in work processes, improving management efficiency and worker cooperation.

[0028] The working principle and beneficial effects of the above technical solution are as follows: To achieve refined worker management, scientific process decomposition, and time coordination, the system lays the foundation for the overall system from the dimensions of safety control, construction efficiency, and management standardization. First, it clarifies the work that workers can perform and their proficiency in performing these tasks, avoiding safety accidents caused by a mismatch between skills and work, while also making work execution more efficient and reducing process delays caused by unfamiliarity with operations. Then, by simulating the construction process and redistributing tasks, it can identify cross-conflicts in the process in advance, and avoid conflicts by adjusting the allocation plan, reducing safety hazards at the construction site from the source. It is especially suitable for complex construction scenarios involving multiple processes and multiple types of work. Furthermore, it derives construction time periods based on preset standards to ensure that the working time of each type of work is accurately matched with the process requirements, avoiding process interruptions or waiting due to unreasonable time arrangements, and improving the continuity of the construction process. Finally, it generates a shift report by generating work start and end times and shift change information and pushes it to the worker's terminal, allowing workers to know their work arrangements in advance, avoiding mis-jobs or omissions due to poor information transmission, and improving the accuracy of worker execution.

[0029] Example 4: Based on Example 1, the dynamic safety path planning and early warning system for associated process tasks includes the following on-site analysis module: The data acquisition unit is used to track the work process of each worker at the construction site when construction begins, analyze the corresponding work actions of each worker at different times, and obtain the current construction data of each worker. The progress derivation unit is used to synchronously construct the completed construction at the construction site based on the current construction data, construct the acceptance conditions corresponding to each completed construction using the on-site execution tasks, and use the acceptance conditions to perform acceptance evaluation on the corresponding completed construction to obtain the on-site quality corresponding to each completed construction. The hazard analysis unit is used to determine the degree of hazard and the scope of hazard corresponding to the completed construction based on the site quality, divide the construction site into areas based on the degree of hazard, and determine several current hazard areas of the construction site.

[0030] In this example, the current construction data represents the data generated by on-site workers while they are working at the construction site; In this example, "completed construction" means that the buildings and work that have been completed at the construction site are already finished. In this example, the acceptance criteria refer to the conditions required to accept the completed construction. In this example, the current danger zone refers to the danger zone that currently exists at the construction site; In this example, the hazard level and range data of the dangerous area can help the hazard warning module clarify the warning priority, avoid the waste of resources and worker apathy caused by indiscriminate warnings, and make the warnings more targeted.

[0031] The working principle and beneficial effects of the above technical solution are as follows: To achieve risk identification, quality control, and safety support, the work process of workers is first tracked through on-site monitoring, recording their actions at different times. This avoids the lag and subjectivity of manually reported data, ensuring that the construction data accurately reflects the actual situation on-site and provides a reliable foundation for subsequent analysis. Then, during construction, the completed construction content is synchronously reconstructed based on the construction data and evaluated in conjunction with preset acceptance conditions, achieving acceptance upon completion of construction. This avoids the accumulation of quality problems caused by delayed acceptance, promptly identifies and rectifys potential quality hazards, and further determines the degree and scope of danger of the completed construction based on the on-site quality. This ensures that the delineation of dangerous areas no longer relies on experience but is based on the actual quality situation, ensuring that no dangerous areas are missed. In this way, the entire process from data collection and progress derivation to hazard identification is automated, eliminating the need for managers to check the quality of each process and manually delineate dangerous areas. This facilitates managers in optimizing the construction process and improving management level.

[0032] Example 5: Based on Example 1, the dynamic safety path planning and early warning system for associated process tasks, wherein the path planning module includes: The status classification unit is used to analyze the list of workers on duty and workers off duty at the construction site within a specified time period based on the start and end times of each worker and the current time, and to determine the current construction location and accommodation location of each worker on duty / off duty. The work planning unit is used to obtain several historical work paths corresponding to each worker, extract relevant path segments from each historical work path according to the corresponding current construction position, and reorganize the relevant path segments according to the distance relationship between each relevant path segment and different current danger areas to obtain a safe work path for each worker. The off-duty prediction unit is used to deduce the off-duty construction position of each off-duty worker at the off-duty time based on the construction work corresponding to each off-duty worker, and at the same time, to deduce the hazard characteristics of each current hazard area at the off-duty time based on the construction progress. The off-get off work planning unit is used to construct an initial off-get off work route based on the off-work work location and accommodation location of each worker, select the safe commuting route with the highest similarity to the initial off-get off work route at the current time, and optimize the safe commuting route using the hazard features to obtain the safe off-get off work route for the worker.

[0033] In this example, the relevant path fragments represent segments from the historical construction path that are related to the current construction location; In this example, the safe commute route is the safe commute route with the highest similarity to the initial commute route. When planning the commute home, the safe commute route with the highest similarity to the initial commute route is selected, eliminating the need to build a new route from scratch, shortening the planning time, and allowing workers to take familiar routes, improving travel convenience and avoiding inefficiency caused by taking excessive detours.

[0034] The working principle and beneficial effects of the above technical solution are as follows: First, a list of workers going to and from work is constructed based on their arrival and departure times and accommodation locations to avoid the disconnect between route planning and workers' actual travel needs, ensuring the relevance of the routes. Then, relevant segments of historical work routes are extracted and combined with the distance to the current danger zone to reconstruct the routes. This reduces adaptation costs by utilizing familiar routes for workers and ensures safety by avoiding danger zones, avoiding the risks caused by blindly planning unfamiliar routes. At the same time, the danger characteristics at the time of departure are predicted, and the route is optimized accordingly to ensure that the departure route can cope with the risk changes brought about by the construction progress. Compared with fixed routes, it is more dynamic and safer. In this way, the planned safe work and departure routes clearly define the expected travel routes of workers. The danger warning module can predict the danger zones that workers may come into contact with in advance and accurately trigger warnings when workers approach, avoiding delayed or false warnings caused by the lack of route information.

[0035] Example 6: Based on Example 5, the dynamic safety path planning and early warning system for associated process tasks further includes: Calculate the safe commute route and safe commute route for each time point; Based on the building distribution at the construction site, the safe commuting route and the safe commuting route are divided into several safe route segments; The safety path information of the construction site is constructed and displayed based on the safety path segment.

[0036] The working principle and beneficial effects of the above technical solution are as follows: Based on the safe commuting route and the safe commuting route, the existing safe routes in the construction site are determined. When external personnel enter the construction site, they can move within the safe range, which effectively ensures the safety of the construction site.

[0037] Example 7: Based on Example 1, the dynamic safety path planning and early warning system for associated process tasks, wherein the hazard early warning module includes: The on-work / off-work tracking unit is used to acquire the real-time on-work / off-work path of the worker when the worker goes to work / off work, and analyze whether the worker has entered the current danger zone based on the real-time on-work / off-work path; The area analysis unit is used to obtain the area presentation characteristics corresponding to the current hazardous area, and generate safe behavior conditions for entering the current hazardous area in combination with the hazard prevention measures at the construction site. A safety evaluation unit is used to acquire the worker's clothing and behavioral characteristics in the current hazardous area, and to evaluate each clothing and behavioral characteristic using the safety behavior conditions. The alert and warning unit is used to remind the worker when the worker's clothing exhibits dangerous characteristics, and to issue an early warning when the worker exhibits dangerous behavioral characteristics.

[0038] In this example, the safety behavior conditions refer to the conditions that must be followed when entering the current hazardous area, such as: wearing a safety helmet and reflective clothing is required, and touching the machinery is not allowed.

[0039] The working principle and beneficial effects of the above technical solution are as follows: First, the paths of workers going to and from work are acquired in real time to accurately determine whether they have entered the current dangerous area. This allows for early detection of the risk of workers accidentally entering dangerous areas, shortening the risk response time and preventing problems from being discovered only after workers have entered the dangerous area. Then, based on the characteristics of the dangerous area and on-site preventive measures, specific safety behavior conditions are generated to avoid ignoring the risk differences between different dangerous areas and to make safety assessments more targeted. Clothing and behavioral characteristics are further verified, and reminders are given for dangerous clothing characteristics and warnings are given for dangerous behavior characteristics. By using interventions of different intensities to adapt to the risk level, indiscriminate warnings can be avoided, which may lead to worker apathy. At the same time, it allows managers to focus on handling high-risk behaviors. In this way, the entire process from path tracking and safety assessment to reminders and warnings is completed automatically, eliminating the need for managers to monitor worker behavior one by one. This significantly reduces the manpower cost of on-site safety inspections and is especially suitable for construction sites with a large number of workers and dispersed dangerous areas.

[0040] Example 8: Based on Example 7, the dynamic safety path planning and early warning system for associated process tasks further includes: A hazard handling unit is used to construct the hazard impact range based on the hazard level and hazard range corresponding to the current hazard area when the worker is injured in the current hazard area. Analyze the worker's injury location and severity, and generate an emergency response plan based on the scope of the current danger, then guide each relevant person to respond to the emergency response plan.

[0041] The working principle and beneficial effects of the above technical solution are as follows: when a worker is injured, the scene is maintained in a timely manner and appropriate treatment is carried out to prevent the situation from escalating further.

[0042] Example 9: Based on Example 6, the dynamic safety path planning and early warning system for associated process tasks further includes: The deep monitoring module is used to obtain the list of workers leaving work at the current time, construct the safe free movement range for each worker by combining the safe path information, and transmit it to the terminal of each worker for display.

[0043] In this example, the terminal used is the worker's mobile phone.

[0044] The working principle and beneficial effects of the above technical solution are as follows: In order to enrich the lives of workers, after work, workers can move around within a prescribed safe and free range of activities, which can not only ensure the safety of workers, but also make them feel happy.

[0045] Example 10: Based on Example 5, the dynamic safety path planning and early warning system for associated work processes optimizes the safe commute path using the hazard characteristics to obtain the safe off-get off work path for the corresponding worker, including: Adjust the original starting point and original ending point of the safe commute route based on the starting point and ending point of the initial commute route to obtain the mid-to-commute route; Based on the hazardous features, the actual distribution of hazards at the construction site is plotted, and the middle and late shift paths corresponding to each worker are marked in the actual distribution of hazards. The first positional relationship between each middle and late shift path and the hazardous features is obtained, as well as the second positional relationship between different middle and late shift paths. Based on the first positional relationship, the middle and end-of-shift routes are adjusted for the first time to obtain the final end-of-shift route for each worker. Based on the second positional relationship analysis, the worker congestion rate corresponding to each site road in the construction site at the time of the end of the workday; The final departure route is adjusted a second time based on the worker congestion rate to obtain several alternative departure routes. The final departure route and detour departure route for each worker are counted separately to construct several safe departure routes for the workers.

[0046] In this example, the first positional relationship represents the positional relationship between the mid-to-late get off work route and the hazardous feature, and the second positional relationship represents the positional relationship between different types of commuting routes; In this example, the "mid-to-end route" refers to the route generated by adjusting the starting and ending points of the "initial end route". In this example, the final departure route represents the route obtained after bypassing the current danger zone.

[0047] The working principle and beneficial effects of the above technical solution are as follows: The process of optimizing safe commuting routes based on hazard characteristics to generate safe commuting routes for workers is as follows: First, by adjusting the start and end points of the safe commuting routes, a suitable commuting route is obtained. Then, the actual distribution of hazards is plotted and the routes are marked based on the hazard characteristics, clarifying the positional relationship between the routes and hazards, and between the routes themselves. Subsequently, based on the positional relationship between the routes and hazards, a first detour adjustment is made to avoid hazardous areas. Based on the positional relationship between the routes, the road congestion rate is analyzed, and a second detour adjustment is made to alleviate the pressure on pedestrian flow. Finally, relevant routes are statistically analyzed to construct a multi-dimensional safe commuting route. This not only ensures the safety of workers on their way home but also takes into account travel efficiency and flexibility, providing commuting workers with a safe travel solution that fits the actual working conditions.

[0048] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
