[0040] Figure 2 is an exemplary flow chart of a task dispatching method according to some embodiments of this specification. Figure 2 As shown, the process 200 includes the following steps. In some embodiments, the process 200 can be executed by a processor.

[0041] Step 210: Obtain construction drawings of the construction project.

[0042] A construction project is a planned, organized series of building and installation activities and their management processes undertaken to achieve a specific construction objective. For example, construction projects include house construction and road paving. A complete construction project can include multiple construction tasks. Construction drawings are design drawings for a construction project. These drawings include construction areas, construction material information, and the construction tasks associated with each construction area.

[0043] For more information about the construction area, construction materials, and construction task items, please refer to the relevant description in step 230.

[0044] In some embodiments, the processor may obtain construction drawings of the construction project by accessing the memory.

[0045] Step 220: Acquire construction environment information collected by at least one sensor.

[0046] Construction environment information refers to the environmental information of the construction area (i.e., the construction site) corresponding to the construction project. In some embodiments, the construction environment information includes environmental data, thermal signal data, and spatial data of the construction area.

[0047] Environmental data refers to the real-time physical environmental parameters of the construction site. For example, environmental data includes at least one of temperature, humidity, wind speed, etc.

[0048] Thermal signal data refers to the characteristic data of heat sources at the construction site. For example, thermal signal data includes the thermal radiation intensity and heat flow direction of the heat source.

[0049] Spatial data refers to the three-dimensional coordinate data of the sensor. It can be used to determine the spatial location of the environmental data and thermal signal data collected by the sensor.

[0050] In some embodiments, the processor can collect environmental data and thermal signal data in real time through sensors installed at various locations in the construction site.

[0051] Sensors include fixed sensors and mobile sensors, etc.

[0052] Fixed sensors are monitoring devices installed at construction sites to collect sensor data from fixed locations. Examples include high-precision thermocouples and thermistor arrays.

[0053] Mobile sensors are monitoring devices carried by construction workers or mounted on mobile devices (such as hard hats or wristbands). They collect data from various locations as construction workers or mobile devices move. Examples include smart hard hats with integrated infrared thermal imaging and portable temperature and humidity meters with GPS positioning. Mobile sensors can collect information about the construction environment over a wider area, enabling the generation of more accurate temperature heat maps.

[0054] In some embodiments, a positioning module is provided inside the sensor, and the positioning module can collect three-dimensional coordinate data of the sensor, and the processor can determine spatial data based on the three-dimensional coordinate data.

[0055] Step 230 : Determine a temperature heat map of the construction project based on the construction drawings and the construction environment information.

[0056] A temperature heat map is a map used to display the temperature distribution at a construction site.

[0057] In some embodiments, the processor can determine the temperature of each location at the construction site through interpolation based on the temperature collected by the sensor and the construction drawings to obtain a temperature heat map.

[0058] In some embodiments, the processor may determine the heat source type based on environmental data and thermal signal data; determine the heat source location information based on thermal signal data and spatial data; and determine the first heat source distribution based on the heat source type and heat source location information.

[0059] Heat source type refers to the source of thermal radiation. For example, heat source types include solar radiation, equipment heat dissipation, and heat storage in building materials.

[0060] In some embodiments, the processor can perform correction and denoising on the thermal signal data based on environmental data using methods such as sliding average filtering and Kalman filtering, and then process the thermal signal data using methods such as time-frequency analysis to determine the heat source type. Processing the thermal signal data using time-frequency analysis includes performing a short-time Fourier transform (STFT) on the thermal signal data to extract frequency domain features, and then determining the heat source type based on the frequency domain features. Different frequency domain features correspond to different heat source types. For example, when the frequency domain features are low-frequency, high-energy features, the heat source type is solar radiation; when the frequency domain features are high-frequency pulses with periodic fluctuations, the heat source type is equipment heat dissipation. Low-frequency, high-energy features refer to high concentrations of energy in lower-frequency thermal signals within the thermal signal data. For example, low-frequency, high-energy features may include energy in the 0-0.1 Hz frequency band exceeding 70%. High-frequency pulses may include pulses in the 1-5 Hz frequency band. The division between low-frequency, high-energy features and high-frequency pulses can be adjusted by technical personnel based on actual circumstances.

[0061] The heat source position information refers to the three-dimensional coordinate data of the heat source.

[0062] In some embodiments, the processor can determine the heat source location information of the heat source by triangulation based on the frequency domain characteristics and spatial data of the thermal signal data. For example, the processor can determine the three-dimensional coordinates of the sensor based on the spatial data. , determine the direction vector of thermal radiation based on the direction of heat flow , based on the three-dimensional coordinates of multiple sensors and the direction vector of thermal radiation, the three-dimensional coordinates of the heat source are calculated by triangulation. and is the direction angle of thermal radiation.

[0063] The first heat source distribution refers to the heat source distribution determined by real-time measured data. The heat source distribution includes the location and type of the heat source on the construction drawing.

[0064] In some embodiments, the processor may perform position mapping and marking on the construction drawing based on the heat source types and heat source location information of all heat sources to obtain a first heat source distribution.

[0065] In some embodiments, the processor can determine construction material information, construction area and at least one construction task item corresponding to the construction area based on the construction drawings; determine multiple grids of the construction drawings based on the construction area; determine multiple thermal field distributions of multiple grids based on the first heat source distribution and construction material information; and determine a temperature thermal map based on multiple thermal field distributions.

[0066] Construction material information refers to information related to the construction materials used in construction drawings. For example, this information includes the type of construction material and its physical properties. Construction material types include steel, concrete, and insulation materials. Physical properties include density, thermal conductivity, specific heat capacity, and thermal emissivity.

[0067] In some embodiments, the processor may extract construction material information based on a material list in a construction drawing.

[0068] A construction zone refers to the multiple functional or operational areas within a construction site. For example, a construction zone includes foundation construction, main construction, and material storage areas. Temperature distribution in different construction zones may vary depending on the type of material, equipment distribution, and construction activities.

[0069] A construction task item refers to one or more construction tasks corresponding to each construction area. For example, the main construction area corresponds to tasks such as wall construction, pipe laying, and precision instrument installation. Different construction tasks have different temperature requirements, so they need to be allocated appropriately based on the temperature heat map.

[0070] In some embodiments, the processor may directly obtain the pre-divided construction areas and construction task items from the construction drawings.

[0071] The grid is the basic unit that makes up each construction area.

[0072] In some embodiments, the processor may obtain the boundaries of each construction area based on the plan and section views of the construction drawings, and further divide the construction area into one or more grids. The grid size of each construction area may be the same or different.

[0073] In some embodiments, the grid size is related to the size of the construction area and the construction tasks corresponding to the construction area. For example, the larger the construction area and the simpler the construction tasks, the larger the grid size; the smaller the construction area and the more complex the construction tasks, the smaller the grid size.

[0074] Thermal field distribution includes the temperature distribution and heat flow direction within each grid in the construction drawings. One grid can correspond to one thermal field distribution.

[0075] In some embodiments, the processor can calculate the temperature distribution and heat flow direction of each grid based on the first heat source distribution and construction material information through a heat conduction and heat radiation model to obtain the thermal field distribution of each grid. The heat conduction and heat radiation model is used to calculate the transfer of heat and heat radiation in the construction area. The heat conduction and heat radiation model can be constructed based on the laws of thermodynamics. For example, based on the first heat source distribution and construction material information, the processor can combine Fourier's heat conduction law to determine the temperature change of different construction materials over time under the influence of the heat source through formula (1).

[0076] (1) in, is the density of the construction material, is the specific heat capacity of the construction material, is the temperature of the construction material, For time, is the thermal conductivity of the construction material, is the heat source term.

[0077] In some embodiments, the processor may further determine the thermal radiation power of different construction materials using formula (2) based on the construction material information and in combination with the Stefan-Boltzmann law.

[0078] (2) in, is the thermal radiation power of the construction material, is the thermal radiation emissivity of the construction material, is the Stefan-Boltzmann constant, is the surface area of ​​the construction material, is the temperature of the construction material.

[0079] In some embodiments, the processor may predict the thermal field distribution of a grid where no sensors are set using a heat conduction and heat radiation model based on the first heat source distribution and the construction material information.

[0080] In some embodiments, the processor may further perform a thermal field distribution simulation using finite element analysis software (eg, ANSYS Fluent) based on the first heat source distribution and the construction material information to obtain the thermal field distribution.

[0081] In some embodiments, the processor may further adjust parameters of the heat conduction and heat radiation models based on the results of the thermal field distribution simulation, thereby improving the prediction accuracy of the heat conduction and heat radiation models.

[0082] In some embodiments, the processor may map the grid to the construction drawing to obtain the thermal field distribution of each location in the construction drawing, and determine the temperature heat map based on the temperature distribution of each location in the construction drawing.

[0083] In some embodiments, the processor may determine a plurality of temperature zones based on a plurality of thermal field distributions; and determine a temperature heat map based on the plurality of temperature zones.

[0084] The temperature zone refers to the temperature range of the construction area. For example, the temperature zone can include low temperature zone, normal temperature zone and high temperature zone.

[0085] In some embodiments, the processor can determine multiple temperature zones based on multiple thermal field distributions in multiple ways. For example, the processor can calculate the mean thermal radiation intensity and the standard deviation of temperature fluctuation in the construction area based on the thermal field distribution of multiple grids contained in the construction area, and determine the temperature zone corresponding to the construction area based on the mean thermal radiation intensity and the standard deviation of temperature fluctuation. For example, when the mean thermal radiation intensity is not greater than 200W / m 2 When the standard deviation of temperature fluctuation is no more than 1°C, the temperature zone is the low temperature zone; when the mean thermal radiation intensity is greater than 200W / m 2 And not more than 400W / m 2 , and / or the temperature fluctuation standard deviation is greater than 1℃ and not greater than 3℃, the temperature zone is the normal temperature zone; when the mean thermal radiation intensity is greater than 400W / m 2 And / or when the standard deviation of temperature fluctuation is greater than 3°C, the temperature zone is a high temperature zone.

[0086] It should be noted that when the mean value of thermal radiation intensity and the standard deviation of temperature fluctuation meet the requirements of normal temperature zone and high temperature zone respectively, the temperature zone is determined to be high temperature zone. For example, when the mean value of thermal radiation intensity is greater than 200 W / m 2And not more than 400W / m 2 When the standard deviation of temperature fluctuation is greater than 3°C, the temperature zone is determined to be a high temperature zone; for example, when the mean thermal radiation intensity is greater than 400W / m 2 When the standard deviation of temperature fluctuation is greater than 1°C and not greater than 3°C, the temperature zone is determined to be a high temperature zone.

[0087] In some embodiments, the division of temperature zones can also be adjusted by technicians according to actual needs.

[0088] In some embodiments, the processor may mark temperature zones of different construction areas in the temperature heat map.

[0089] In some embodiments, the processor may use different colors to mark different temperature zones, for example, green for low temperature zones, yellow for normal temperature zones, and red for high temperature zones.

[0090] In some embodiments, the processor may also determine the RGB value corresponding to the temperature zone based on the average temperature of the temperature zone in the construction area through a temperature-RGB function, and mark the temperature zone in the construction area with the color corresponding to the RGB value in the temperature heat map.

[0091] The Temperature-RGB function is used to represent the relationship between the mean temperature and the color of the temperature zones within the construction area. The Temperature-RGB function can be manually set by technicians.

[0092] In some embodiments, the processor may further mark the location of the heat source and the direction of the heat flow in the temperature heat map.

[0093] By using different colors to mark temperature zones and combining the location of heat sources and the direction of heat flow, construction workers and managers can quickly identify high-temperature areas, making the temperature heat map more intuitive and clear.

[0094] In some embodiments of this specification, dividing the construction area into multiple grids enables more accurate monitoring and analysis of the thermal field distribution in each construction area. By varying the grid size, the accuracy and efficiency of thermal field distribution calculations can be optimized for different construction areas. Considering the impact of construction material information on thermal field distribution, temperature heat maps generated based on this information are more accurate.

[0095] Step 240: dispatch construction tasks based on the temperature heat map.

[0096] In some embodiments, the processor can determine the temperature of the location corresponding to the construction task item based on the temperature heat map, determine the requirements of the construction task item for the work ability of the construction personnel based on the construction drawings, determine the construction personnel who meet both the temperature requirements and the work ability requirements as the construction personnel corresponding to the construction task item and assign the construction tasks.

[0097] In some embodiments, the processor can determine the task temperature condition of at least one construction task item; based on multiple temperature zones, filter out tasks to be dispatched that meet the task temperature condition; determine target construction personnel based on the tasks to be dispatched and the multiple temperature zones, and dispatch construction tasks to the target construction personnel. For more information, see Figure 3 And related instructions.

[0098] Some embodiments of this specification utilize sensors to collect multi-dimensional construction environment information, improving the accuracy and real-time nature of high-temperature monitoring. A temperature heat map, based on construction drawings and construction environment information, can be generated. This heat map can then be used to more effectively assign construction tasks, thereby ensuring the health of construction workers while improving construction quality and efficiency and ensuring smooth progress.

[0099] Figure 3 This is an exemplary flow chart of dispatching construction tasks according to some embodiments of this specification. Figure 3 As shown, the process 300 includes the following steps. In some embodiments, the process 300 can be executed by a processor.

[0100] Step 310: Determine a task temperature condition of at least one construction task item.

[0101] For more information about the construction task items, please refer to the relevant instructions in step 230.

[0102] Task temperature conditions refer to the temperature conditions required to ensure the normal execution of a construction task. Different construction tasks may require different temperature zones. For example, temperature-sensitive construction tasks such as precision instrument installation and operating high-precision electric vehicle equipment are suitable for low-temperature zones; construction tasks such as wall construction are suitable for normal temperature zones; and construction tasks such as remote equipment inspection are suitable for high-temperature zones.

[0103] For more information about temperature heat maps and temperature zones, see Figure 2 And related instructions.

[0104] In some embodiments, the processor may query a first preset table based on at least one construction task item to determine the task temperature condition corresponding to the construction task item.

[0105] The first preset table includes correspondences between different construction task items and task temperature conditions. The first preset table can be constructed by engineers based on historical experience.

[0106] Step 320 : Based on the multiple temperature zones of the temperature heat map, filter out tasks to be dispatched that meet the task temperature conditions.

[0107] Tasks to be dispatched refer to construction tasks that need to be assigned to construction personnel for execution.

[0108] In some embodiments, for a construction area, the processor can match the temperature zones of the construction area in the temperature heat map with the task temperature conditions of the construction task items corresponding to the construction area, and determine the construction task items whose temperature zones meet the task temperature conditions as tasks to be dispatched.

[0109] Step 330 : Determine target construction personnel based on the tasks to be assigned and the multiple temperature zones, and assign construction tasks to the target construction personnel.

[0110] Target construction workers refer to construction workers whose heat resistance supports the execution of the assigned tasks in the temperature zone.

[0111] In some embodiments, the processor may determine the temperature requirements of the task to be dispatched based on the temperature zone where the task to be dispatched is located, and determine the construction personnel who meet the temperature requirements and work ability requirements of the task to be dispatched as the target construction personnel corresponding to the task to be dispatched.

[0112] In some embodiments, the processor may obtain a heat resistance index of the construction worker; in response to the heat resistance index satisfying the target temperature zone, the construction worker is determined as a target construction worker in the target temperature zone.

[0113] The heat resistance index is a parameter used to measure the construction workers' ability to work in high temperature environments. The higher the heat resistance index, the stronger the construction workers' ability to work in high temperature environments.

[0114] In some embodiments, the heat tolerance index is related to the health status of the construction workers. The processor can determine the heat tolerance index based on the health data of the construction workers. The health data includes physical endurance score, basal body temperature, and the number of historical high temperature discomfort episodes. The higher the physical endurance score, the lower the basal body temperature, and the fewer historical high temperature discomfort episodes, the higher the heat tolerance index. In some embodiments, the processor can calculate the heat tolerance index of the construction workers based on the health data using formula (3).

[0115] (3) in, It is an indicator of heat resistance. To score physical endurance, is the basal body temperature, This is the historical number of high temperature discomfort events.

[0116] In some embodiments, the processor can obtain the physical endurance score and basal body temperature of the construction workers based on the physical examination data of the construction workers pre-stored in the memory, and obtain the historical number of high temperature discomfort based on historical work records.

[0117] In some embodiments, different temperature zones have different requirements for heat resistance indexes. For example, a high temperature zone requires a heat resistance index of no less than 2, and a normal temperature zone requires a heat resistance index of no less than 1.5.

[0118] In some embodiments, the processor may determine a construction worker whose heat resistance index meets the requirements of a target temperature zone as a target construction worker corresponding to the target temperature zone. The target temperature zone is a temperature zone where there are currently tasks to be assigned.

[0119] In some embodiments of this specification, target construction workers are identified and tasks are assigned based on the construction workers' heat resistance indicators, which can ensure that the construction workers can work in a temperature environment suitable for them, avoid damage to their health due to high temperature exposure, and ensure the efficient completion of construction tasks.

[0120] In some embodiments, the processor can obtain the work ability of the target construction personnel from the memory, and based on the work ability and the tasks to be assigned in the target temperature zone, match them through a second preset table to obtain a task to be assigned that matches the work ability, and assign the task to be assigned as a construction task to the target construction personnel. Among them, the work ability includes work efficiency, professional skill level, etc. The matching of the task to be assigned and the work ability can be that the professional skill level of the construction personnel meets the requirements of the task to be assigned. For example, when the task to be assigned is electrical wiring, construction personnel with an electrician skill level of four or above are matched with the task to be assigned.

[0121] The second preset table includes the correspondence between the tasks to be assigned and the work capabilities, and the second preset table can be constructed based on experience.

[0122] In some embodiments, the processor can determine a time series heat map for a preset future time based on the impact of the dispatched tasks on the distribution of the first heat source; obtain priority information of the tasks to be dispatched within the preset future time; determine the priority tasks and the task temperature conditions of the priority tasks based on the priority information; match and dispatch the priority tasks based on the time series heat map and the task temperature conditions of the priority tasks.

[0123] Dispatched tasks refer to construction tasks that have been assigned to construction personnel and are waiting to be executed.

[0124] In some embodiments, during the construction process, certain construction tasks themselves will generate heat sources, such as welding operations, hoisting equipment operation, etc. The heat generated by these construction tasks will affect the thermal field distribution at the construction site. The impact of the dispatched task on the first heat source distribution includes the time when the heat source is generated, the type of heat source, the location information of the heat source, and the duration of the heat source. The processor can obtain historical environmental data and historical thermal signal data when executing the same historical construction task item as the dispatched task based on historical data, determine the heat source type and heat source location information and the duration of the heat source generated when executing the dispatched task based on the historical environmental data and the historical thermal signal data, determine the time when the heat source is generated in combination with the execution time of the dispatched task, and obtain the impact of the dispatched task on the first heat source distribution.

[0125] In some embodiments, in order to more accurately determine the impact of the dispatched tasks on the first heat source distribution, the processor may further combine the predicted weather within a preset future time to obtain the impact of the dispatched tasks on the first heat source distribution.

[0126] For more information on how to determine the heat source type and heat source location information, please refer to the relevant description in step 230.

[0127] A time-series heat map is a dynamic temperature heat map within a preset future timeframe. The preset future timeframe can be the next 6 hours, the next 12 hours, etc.

[0128] In some embodiments, the processor may generate a time series heat map based on the impact of the dispatched tasks on the first heat source distribution using a time series prediction algorithm, including but not limited to an autoregressive integrated moving average model (ARIMA) and a long short-term memory network (LSTM).

[0129] Priority information indicates the importance of tasks to be assigned within a preset timeframe. The greater the impact of a task on the progress and quality of the entire construction project, the higher its priority. For example, concrete pouring is a critical path task that must be completed within a specific timeframe, otherwise it will impact the overall progress of the project. Therefore, this task has a higher priority.

[0130] In some embodiments, the processor may query a third preset table based on the tasks to be dispatched, obtain the priorities corresponding to the tasks to be dispatched, and sort the tasks to be dispatched according to the priorities.

[0131] The third preset table includes the correspondence between different construction tasks and priorities, and the third preset table can be constructed based on experience.

[0132] Priority tasks refer to tasks with higher priority to be dispatched.

[0133] In some embodiments, the processor may determine N to-be-dispatched tasks with the highest priority as priority tasks, where N may be set based on experience.

[0134] In some embodiments, the processor can match the target construction personnel corresponding to the priority task based on the task temperature conditions of the priority task and multiple temperature zones in the time-series heat map using the same method as determining the target construction personnel, and assign the priority task to the target construction personnel.

[0135] In some embodiments of the present specification, based on the impact of the assigned tasks on the distribution of the first heat source, a time-series heat map at a preset time in the future is predicted, which can plan task allocation in advance, ensure the smooth progress of construction tasks with higher priority, and avoid affecting the progress and quality of the construction project.

[0136] In some embodiments, in response to the timing heat map not matching the task temperature condition of the priority task, the processor may adjust the dispatched task; update the timing heat map based on the adjusted dispatched task; and match and dispatch the priority task based on the updated timing heat map and the task temperature condition of the priority task.

[0137] In some embodiments, when the temperature zones in the temporal heat map do not match the temperature conditions of the priority tasks, the processor may adjust the assigned tasks. Adjustments may include, but are not limited to, adjusting the execution order of the assigned tasks, canceling lower-priority assigned tasks, changing the construction area corresponding to the assigned tasks, or any combination thereof.

[0138] In some embodiments, the processor can redetermine the impact of the adjusted dispatched tasks on the first heat source distribution based on the adjusted dispatched tasks, and redetermine the updated timing heat map based on the impact of the adjusted dispatched tasks on the first heat source distribution through the method of determining the timing heat map as described above.

[0139] In some embodiments, the processor matches the target construction personnel corresponding to the priority task based on the multiple temperature zones in the updated time-series heat map and the task temperature conditions of the priority task using the same method as that used to determine the target construction personnel, and assigns the priority task to the target construction personnel.

[0140] In some embodiments, in response to the timing heat map matching the task temperature condition of the priority task, the processor completes dispatching the priority task. Otherwise, the processor repeats the above steps of adjusting the dispatched tasks, updating the timing heat map, and matching and dispatching the priority task until the timing heat map matches the task temperature condition of the priority task, thereby completing dispatching the priority task.

[0141] In some embodiments of the present specification, by adjusting the assigned construction tasks, updating the temporal heat map, and re-matching and assigning priority tasks based on the updated temporal heat map, it is possible to ensure that the priority tasks can be smoothly executed under appropriate temperature conditions.

[0142] In some embodiments, the processor can determine the second heat source distribution based on the dispatched task being executed, determine the abnormal heat source area based on the first heat source distribution and the second heat source distribution, and obtain the results of the abnormal heat source area investigation. For more information about abnormality investigation, see Figure 4 And related instructions.

[0143] In some embodiments of the present specification, tasks to be assigned and target construction personnel that match each other are screened out based on the temperature zones and task temperature conditions of the temperature heat map, thereby avoiding blind task assignment and enabling construction personnel to work at a suitable temperature, thereby avoiding heatstroke among construction personnel and the inability to carry out construction tasks due to temperature influences, thereby ensuring the health of construction personnel and the smooth progress of construction tasks.

[0144] Figure 4 This is an exemplary flow chart of abnormality troubleshooting according to some embodiments of this specification. Figure 4 As shown, the process 400 includes the following steps: In some embodiments, the process 400 may be executed by a processor.

[0145] Step 410: Determine a second heat source distribution based on the construction task item being executed.

[0146] The second heat source distribution refers to the distribution of heat sources generated by executing the construction task item. The second heat source distribution includes the construction area where the heat source is located.

[0147] In some embodiments, the processor can determine whether the construction task item being executed will generate a heat source by querying the fourth preset table based on the construction task item being executed, and then determine the construction area corresponding to the construction task item being executed that generates the heat source to obtain a second heat source distribution.

[0148] The fourth preset table includes a correspondence between construction task items and whether a heat source is generated. The fourth preset table can be set based on experience.

[0149] Step 420: Determine a heat source abnormality area based on the first heat source distribution and the second heat source distribution.

[0150] For more information about the first heat source distribution, please refer to the relevant description in step 230.

[0151] The abnormal heat source area refers to a construction area where a heat source exists in the first heat source distribution but does not exist in the second heat source distribution.

[0152] In some embodiments, the processor can compare the first heat source distribution and the second heat source distribution to obtain heat sources that exist in the first heat source distribution but not in the second heat source distribution, and determine the construction areas where these heat sources are located as abnormal heat source areas, and the remaining areas as normal heat source areas.

[0153] Step 430: Obtain the results of the inspection of the abnormal heat source area.

[0154] Abnormal investigation refers to the inspection and analysis of abnormal heat source areas to determine the nature and cause of the abnormal heat source.

[0155] The investigation result refers to the result of the abnormal investigation of the abnormal heat source area. The investigation results include normal and abnormal.

[0156] In some embodiments, the safety officer can conduct anomaly investigation by manual on-site inspection, retrieving image data of the abnormal heat source area, retrieving operating data of equipment in the abnormal heat source area for investigation, etc., determine the investigation results, and input the investigation results into the memory through the user terminal. The processor obtains the investigation results of the abnormal heat source area stored in the memory.

[0157] In some embodiments, when the safety officer conducts manual on-site inspections, he or she may directly handle faults or hidden dangers that can be directly resolved, and input the processing results into a memory.

[0158] Step 441 : In response to the troubleshooting result being normal, a temperature heat map is determined based on the first heat source distribution.

[0159] The inspection results are normal, indicating that the heat source in the abnormal heat source area is generated by the normal operation of lighting equipment and production equipment during the construction process, and will not affect the construction.

[0160] In some embodiments, in response to the troubleshooting result being normal, the processor may determine a temperature heat map based on the first heat source distribution.

[0161] For more information on how to determine the temperature heat map, please refer to the relevant description in step 230.

[0162] Step 442 : In response to the checking result being abnormal, a temperature heat map is determined based on the second heat source distribution.

[0163] The result of the investigation is abnormal, indicating that the abnormal heat source area may have equipment failure, fire hazards or other safety hazards. When the investigation result is abnormal, it indicates that the first heat source distribution determined based on the heat source type and heat source location information of the construction site may not be credible, and thus the temperature heat map determined based on the first heat source distribution is inaccurate. The processor can determine the temperature heat map based on the second heat source distribution. For example, the processor can determine the heat source type, heat source duration and other information of the second heat source corresponding to the abnormal heat source area. Based on the heat source type, heat source duration and other information of the second heat source corresponding to the abnormal heat source area, the processor can query and determine a similar second heat source similar to the second heat source in the abnormal heat source area in the normal heat source area, and determine the first heat source corresponding to the similar second heat source as the reference first heat source in the abnormal heat source area. The processor can replace the original first heat source in the abnormal heat source area with the reference first heat source, redetermine the first heat source distribution, and then determine the temperature heat map.

[0164] In some embodiments, in response to an abnormality in the inspection result, the processor can issue an early warning for the abnormal heat source area in various ways. For example, the processor can use sound and light warnings to alert construction workers around the abnormal heat source area, notify management personnel via text message, or display the early warning information of the abnormal heat source area on the interface of the task dispatch system.

[0165] In some embodiments of this specification, by comparing and analyzing the first and second heat source distributions, abnormal heat source areas can be promptly identified, investigated, and the investigation results determined. If the investigation results are normal, the temperature heat map is updated using the real-time collected first heat source distribution, accurately reflecting the real-time thermal field distribution of the construction site. If the investigation results are abnormal, potential safety hazards can be promptly addressed to ensure construction site safety.
