[0049] Figure 2 This is an exemplary flowchart illustrating a task dispatch method according to some embodiments of this specification. Figure 2 As shown, process 200 includes the following steps. In some embodiments, process 200 may be executed by a processor.

[0050] Step 210: Obtain the construction drawings for the construction project.

[0051] A construction project refers to a series of planned and organized building and installation activities and their management processes undertaken to achieve a specific construction goal. For example, construction projects include building construction and road paving. A complete construction project may include multiple construction tasks. Construction drawings refer to the design drawings for a construction project. Construction drawings include the construction area, construction material information, and the construction tasks associated with each construction area.

[0052] For more information on the construction area, construction materials, and construction tasks, please refer to the relevant instructions in step 230.

[0053] In some embodiments, the processor can access the construction drawings of a construction project by accessing memory.

[0054] Step 220: Obtain construction environment information collected by at least one sensor.

[0055] 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, construction environment information includes environmental data, thermal signal data, and spatial data of the construction area.

[0056] Environmental data refers to real-time physical environmental parameters at the construction site. For example, environmental data includes at least one of temperature, humidity, and wind speed.

[0057] 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 of the heat source, the direction of heat flow, etc.

[0058] Spatial data refers to the three-dimensional coordinate data of a sensor. Spatial data allows us to determine the spatial location corresponding to the environmental and thermal signal data collected by the sensor.

[0059] In some embodiments, the processor can acquire environmental data and thermal signal data in real time through sensors installed at various locations on the construction site.

[0060] Sensors include fixed sensors and mobile sensors.

[0061] Fixed sensors refer to monitoring equipment installed at a construction site to collect sensing data at fixed locations. Examples of fixed sensors include high-precision thermocouples and thermistor arrays.

[0062] Mobile sensors are monitoring devices carried or installed on mobile devices (such as safety helmets, wristbands, etc.) by construction workers. Mobile sensors collect data from different locations as the workers or mobile devices move. Examples include smart safety helmets with integrated infrared thermal imaging and portable temperature and humidity meters with GPS positioning. Mobile sensors enable the collection of information about a wider range of construction environments, generating more accurate temperature and heat maps.

[0063] In some embodiments, the sensor is equipped with a positioning module, which can collect the sensor's three-dimensional coordinate data, and the processor can determine spatial data based on the three-dimensional coordinate data.

[0064] Step 230: Based on the construction drawings and construction environment information, determine the temperature heat map of the construction project.

[0065] A temperature heat map is a map used to display the temperature distribution at a construction site.

[0066] In some embodiments, the processor can determine the temperature at various locations on the construction site based on the temperature collected by sensors and construction drawings, and obtain a temperature heat map by interpolation and other means.

[0067] 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.

[0068] Heat source type refers to the category of heat radiation sources. For example, heat source types include solar radiation, equipment heat dissipation, and heat storage in building materials.

[0069] In some embodiments, the processor can correct and denoise the thermal signal data based on environmental data using methods such as moving average filtering and Kalman filtering, and then process the thermal signal data using time-frequency analysis to determine the heat source type. The time-frequency analysis process 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 these features. Different frequency domain features correspond to different heat source types. For example, when the frequency domain feature is low-frequency, high-energy, the heat source type is solar radiation; when the frequency domain feature is a periodic fluctuation of high-frequency pulses, the heat source type is equipment cooling, etc. The low-frequency, high-energy feature refers to the high concentration of energy in the lower-frequency thermal signal data; for example, the energy proportion in the 0-0.1Hz frequency band may exceed 70%. High-frequency pulses may be pulses in the 1-5Hz frequency band, etc. The classification of low-frequency, high-energy features and high-frequency pulses can also be adjusted by technicians according to actual conditions.

[0070] Heat source location information refers to the three-dimensional coordinate data of the heat source.

[0071] In some embodiments, the processor can determine the location information of the heat source based on the frequency domain characteristics and spatial data of the thermal signal data, using methods such as triangulation. For example, the processor can determine the three-dimensional coordinates of the sensor based on the spatial data. Determining 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 using a triangulation method. and The directional angle of thermal radiation.

[0072] The primary heat source distribution refers to the distribution of heat sources determined through real-time measured data. This distribution includes the location and type of heat sources on the construction drawings.

[0073] In some embodiments, the processor can perform location mapping and annotation on the construction drawings based on the heat source type and location information of all heat sources to obtain the first heat source distribution.

[0074] In some embodiments, the processor may determine construction material information, construction area, and at least one construction task item corresponding to the construction area based on construction drawings; determine multiple grids of the construction drawings based on the construction area; determine multiple thermal field distributions of the multiple grids based on the distribution of a first heat source and construction material information; and determine a temperature thermal map based on the multiple thermal field distributions.

[0075] Construction material information refers to information related to the construction materials used in the construction drawings. For example, construction material information includes the type of construction material and its physical properties. The types of construction materials include steel, concrete, and insulation materials. Physical properties include the density, thermal conductivity, specific heat capacity, and thermal emissivity of the construction materials.

[0076] In some embodiments, the processor can extract construction material information based on the bill of materials in the construction drawings.

[0077] A construction area refers to the multiple functional or operational areas encompassed by a construction site. For example, a construction area may include a foundation construction area, a main structure construction area, and a material storage area. The temperature distribution in different construction areas may vary depending on the type of materials, equipment distribution, and construction activities.

[0078] A construction task item refers to one or more construction tasks corresponding to each construction area. For example, the construction tasks corresponding to the main construction area include bricklaying, pipe laying, and precision instrument installation. Different construction tasks have different temperature requirements, and it is necessary to allocate different construction tasks reasonably according to the temperature heat map.

[0079] In some embodiments, the processor can directly obtain the pre-defined construction areas and construction task items from the construction drawings.

[0080] The grid is the basic unit that makes up each construction area.

[0081] In some embodiments, the processor can obtain the boundaries of each construction area based on the plan and section views of the construction drawings, and then divide the construction area into one or more grids. The grid size of each construction area can be the same or different.

[0082] 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.

[0083] The thermal field distribution includes the temperature distribution and heat flow direction within each grid in the construction drawings. One grid corresponds to one thermal field distribution.

[0084] In some embodiments, the processor can calculate the temperature distribution and heat flow direction of each grid based on the distribution of the first heat source and the construction material information, using 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, the processor can determine the temperature change law of different construction materials over time under the influence of the heat source by formula (1), based on the distribution of the first heat source and the construction material information, combined with Fourier's law of heat conduction.

[0085] (1) in, The density of the construction materials, The specific heat capacity of the construction material. The temperature of the construction materials, For time, For the thermal conductivity of construction materials, This is a heat source term.

[0086] In some embodiments, the processor can also determine the thermal radiation power of different construction materials based on construction material information and in conjunction with the Stefan-Boltzmann law, using formula (2).

[0087] (2) in, The thermal radiation power of the construction materials. The thermal emissivity of the construction materials. The Stefan-Boltzmann constant is... The surface area of ​​the construction materials. The temperature of the construction materials.

[0088] In some embodiments, the processor can predict the thermal field distribution of a grid without sensors by using a heat conduction and heat radiation model based on the distribution of a first heat source and construction material information.

[0089] In some embodiments, the processor can also simulate the thermal field distribution using finite element analysis software (e.g., ANSYS Fluent) based on the distribution of the first heat source and the construction material information to obtain the thermal field distribution.

[0090] In some embodiments, the processor can also adjust the 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.

[0091] In some embodiments, the processor can map the mesh to the construction drawings to obtain the thermal field distribution at each location in the construction drawings, and determine the temperature thermal map based on the temperature distribution at each location in the construction drawings.

[0092] In some embodiments, the processor can determine multiple temperature zones based on multiple thermal field distributions; and determine a temperature heat map based on the multiple temperature zones.

[0093] Temperature zone refers to the temperature range of the construction area. For example, temperature zone can include low temperature zone, normal temperature zone, and high temperature zone.

[0094] In some embodiments, the processor can determine multiple temperature zones based on multiple thermal field distributions in various ways. For example, the processor can calculate the mean thermal radiation intensity and standard deviation of temperature fluctuation of 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 standard deviation of temperature fluctuation. For instance, when the mean thermal radiation intensity is no greater than 200 W / m²... 2 Furthermore, when the standard deviation of temperature fluctuation is no greater than 1℃, the temperature range is considered a low-temperature range; when the average thermal radiation intensity is greater than 200W / m², the temperature range is considered a low-temperature range. 2 And not greater than 400W / m 2 When the standard deviation of temperature fluctuation is greater than 1℃ but not greater than 3℃, the temperature range is considered the normal temperature range; when the average thermal radiation intensity is greater than 400W / m² 2 When the standard deviation of temperature fluctuation is greater than 3°C, the temperature zone is considered a high-temperature zone.

[0095] It should be noted that the temperature zone is defined as the high-temperature zone when the mean thermal radiation intensity and the standard deviation of temperature fluctuation meet the requirements of the normal temperature zone and the high-temperature zone, respectively. For example, when the mean thermal radiation intensity is greater than 200 W / m². 2 And not greater than 400W / m 2 When the standard deviation of temperature fluctuation is greater than 3℃, the temperature zone is defined as a high-temperature zone; another example is when the average thermal radiation intensity is greater than 400W / m². 2 When the standard deviation of temperature fluctuation is greater than 1℃ but not greater than 3℃, the temperature zone is defined as the high temperature zone.

[0096] In some embodiments, the method of dividing the temperature zones can also be adjusted by technicians according to actual needs.

[0097] In some embodiments, the processor can mark temperature zones of different construction areas in a temperature heat map.

[0098] In some embodiments, the processor can use different colors to indicate different temperature zones. For example, green indicates a low temperature zone, yellow indicates a normal temperature zone, and red indicates a high temperature zone.

[0099] In some embodiments, the processor can also determine the RGB value corresponding to the temperature zone based on the average temperature of the temperature zone in the construction area using the temperature-RGB function, and mark the temperature zone of the construction area in the temperature heat map with the color corresponding to the RGB value.

[0100] The temperature-RGB function is used to represent the correspondence between the average temperature of a construction area and the marked colors. The temperature-RGB function can be manually set by technicians.

[0101] In some embodiments, the processor can also mark the location of heat sources and the direction of heat flow in the temperature heat map.

[0102] By using different colors to mark temperature zones, combined with the location of heat sources and the direction of heat flow, construction workers and managers can quickly identify high-temperature areas, making temperature heat maps more intuitive and clear.

[0103] In some embodiments of this specification, the construction area is divided into multiple grids, enabling more accurate monitoring and analysis of the thermal field distribution in each construction area. By changing the grid size, the accuracy and efficiency of thermal field distribution calculations for different construction areas can be satisfied. Considering the influence of construction material information on the thermal field distribution, temperature and heat maps determined based on construction material information are more accurate.

[0104] Step 240: Distribute construction tasks based on the temperature heat map.

[0105] In some embodiments, the processor can determine the temperature of the location corresponding to the construction task based on a temperature heat map, determine the work ability requirements of the construction personnel for the construction task based on the construction drawings, and identify the construction personnel who meet both the temperature requirements and the work ability requirements as the construction personnel corresponding to the construction task and assign the construction task.

[0106] In some embodiments, the processor can determine the task temperature conditions for at least one construction task; filter out tasks whose task temperature conditions are met based on multiple temperature zones; 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. For more details, see [link to relevant documentation]. Figure 3 And related explanations.

[0107] Some embodiments in this specification utilize sensors to collect multi-dimensional construction environment information, thereby improving the accuracy and real-time performance of high-temperature monitoring. By determining a temperature heat map based on construction drawings and environmental information, construction tasks can be more rationally assigned, thus improving construction quality and efficiency while protecting the health of construction personnel and ensuring the smooth progress of construction tasks.

[0108] Figure 3This is an exemplary flowchart illustrating the dispatching of construction tasks according to some embodiments of this specification. Figure 3 As shown, process 300 includes the following steps. In some embodiments, process 300 may be executed by a processor.

[0109] Step 310: Determine the task temperature conditions for at least one construction task.

[0110] For more information on the construction tasks, please refer to the relevant instructions in step 230.

[0111] Task temperature conditions refer to the temperature conditions required to ensure the normal execution of a construction task. Different construction tasks may need to be carried out in different temperature zones. For example, temperature-sensitive construction tasks such as installing precision instruments and operating high-precision electric vehicle equipment are suitable for low-temperature zones; construction tasks such as bricklaying are suitable for normal-temperature zones; and construction tasks such as remote equipment inspection are suitable for high-temperature zones.

[0112] For more information on temperature heat maps and temperature zones, please see [link / reference]. Figure 2 And related explanations.

[0113] In some embodiments, the processor may query a first preset table based on at least one construction task item to determine the task temperature conditions corresponding to the construction task item.

[0114] The first pre-set table includes the correspondence between different construction tasks and the corresponding temperature conditions. The first pre-set table can be constructed by engineers based on historical experience.

[0115] Step 320: Based on multiple temperature zones in the temperature heat map, select tasks that meet the temperature conditions to be dispatched.

[0116] Tasks to be assigned refer to construction tasks that need to be assigned to construction personnel.

[0117] In some embodiments, for a construction area, the processor can match the temperature zone of the construction area in the temperature heat map with the task temperature conditions of the corresponding construction task items, and determine the construction task items whose temperature zone meets the task temperature conditions as tasks to be dispatched.

[0118] Step 330: Based on the tasks to be assigned and multiple temperature zones, identify the target construction personnel and assign construction tasks to them.

[0119] The target construction personnel refers to construction personnel whose heat resistance supports them in performing assigned tasks within the temperature range.

[0120] In some embodiments, the processor can determine the temperature requirements of the task to be assigned based on the temperature zone where the task is located, and identify the construction personnel who meet the temperature requirements and work capacity requirements of the task to be assigned as the target construction personnel corresponding to the task to be assigned.

[0121] In some embodiments, the processor can acquire the heat resistance index of the construction personnel; in response to the heat resistance index meeting the target temperature zone, the construction personnel are identified as target construction personnel in the target temperature zone.

[0122] Heat resistance is a parameter used to measure the ability of construction workers to work in high-temperature environments. The higher the heat resistance index, the stronger the ability of construction workers to work in high-temperature environments.

[0123] In some embodiments, the heat tolerance index is related to the health status of construction workers. The processor can determine the heat tolerance index based on the health data of construction workers. The health data includes physical endurance score, basal body temperature, and number of historical high-temperature discomforts. The higher the physical endurance score, the lower the basal body temperature, and the fewer the number of historical high-temperature discomforts, the higher the heat tolerance index. In some embodiments, the processor can calculate the heat tolerance index of construction workers based on health data using formula (3).

[0124] (3) in, As an indicator of heat resistance, Assess physical endurance. Basal body temperature, This represents the number of times historical high temperatures have caused discomfort.

[0125] In some embodiments, the processor can obtain physical endurance scores and basal body temperature based on pre-stored physical examination data of construction workers in memory, and obtain the number of times historical high-temperature discomfort has occurred based on historical work records.

[0126] In some embodiments, different temperature zones have different requirements for heat resistance indicators. For example, the high-temperature zone requires a heat resistance indicator of not less than 2, while the normal-temperature zone requires a heat resistance indicator of not less than 1.5, etc.

[0127] In some embodiments, the processor can identify construction workers whose heat resistance indicators meet the requirements of the target temperature zone as the target construction workers corresponding to that target temperature zone. The target temperature zone refers to the temperature zone where there are currently tasks to be assigned.

[0128] In some embodiments of this specification, the target construction personnel are identified and tasks are assigned based on their heat resistance index. This ensures that construction personnel can work in a temperature environment suitable for them, avoiding health damage caused by high temperature exposure, while also ensuring the efficient completion of construction tasks.

[0129] In some embodiments, the processor can retrieve the work capabilities of the target construction worker from memory, match these capabilities with tasks to be assigned in the target temperature zone using a second preset table, obtain tasks matching the work capabilities, and assign these tasks as construction tasks to the target construction worker. Work capabilities include work efficiency, professional skill level, etc. Matching the task to be assigned with the work capabilities can be achieved by ensuring the construction worker's professional skill level meets the requirements of the task. For example, when the task to be assigned is electrical wiring, a construction worker with an electrician skill level of four or above is matched with the task.

[0130] The second preset table includes the correspondence between tasks to be assigned and work capabilities. The second preset table can be constructed based on experience.

[0131] In some embodiments, the processor may determine a time-series heat map for a future preset time period based on the impact of dispatched tasks on the distribution of the first heat source; obtain priority information of tasks to be dispatched within the future preset time period; determine priority tasks and task temperature conditions of priority tasks based on the priority information; and match and dispatch priority tasks based on the time-series heat map and task temperature conditions of priority tasks.

[0132] Distributed tasks refer to construction tasks that have been assigned to construction personnel and are yet to be performed.

[0133] In some embodiments, certain construction tasks themselves generate heat sources during construction, such as welding operations and hoisting equipment operation. The heat generated by these construction tasks affects the thermal field distribution at the construction site. The impact of assigned tasks on the first heat source distribution includes the time of heat source generation, heat source type, heat source location information, and heat source duration. The processor can obtain historical environmental data and historical thermal signal data from historical construction tasks that were executed similarly to the assigned tasks. Based on the historical environmental data and historical thermal signal data, it determines the heat source type, heat source location information, and heat source duration generated when executing the assigned tasks. Combining this with the execution time of the assigned tasks, it determines the time of heat source generation, thus obtaining the impact of the assigned tasks on the first heat source distribution.

[0134] In some embodiments, in order to more accurately determine the impact of the assigned tasks on the distribution of the first heat source, the processor may also combine the predicted weather within a preset time period to obtain the impact of the assigned tasks on the distribution of the first heat source.

[0135] For more information on how to determine the type and location of the heat source, please refer to the relevant instructions in step 230.

[0136] A time-series heat map is a dynamic temperature heat map over a predetermined future time period. The predetermined future time period can be 6 hours, 12 hours, etc.

[0137] In some embodiments, the processor can generate a time-series heat map based on the impact of dispatched tasks on the distribution of the first heat source, using time-series prediction algorithms, etc. Time-series prediction algorithms include, but are not limited to, Autoregressive Integrated Moving Average (ARIMA) models, Long Short-Term Memory (LSTM) models, etc.

[0138] Priority information indicates the importance of tasks to be assigned within a predetermined future timeframe. The greater the impact of a task on the overall project schedule and quality, the higher its priority. For example, concrete pouring is a critical path task that needs to be completed within a specific timeframe; otherwise, it will affect the overall project schedule. Therefore, this task has a high priority.

[0139] In some embodiments, the processor may query a third preset table based on the tasks to be dispatched to obtain the priority of the tasks to be dispatched, and sort the tasks to be dispatched according to the priority.

[0140] The third preset table includes the correspondence between different construction tasks and priorities, and the third preset table can be constructed based on experience.

[0141] Priority tasks refer to tasks that have a higher priority and are yet to be assigned.

[0142] In some embodiments, the processor may identify the N highest-priority tasks to be dispatched as priority tasks, where N may be set based on experience.

[0143] In some embodiments, the processor can determine 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 dispatch the priority task to the target construction personnel.

[0144] In some embodiments of this specification, based on the impact of assigned tasks on the distribution of the first heat source, a time-series heat map for a preset time period is predicted, which can plan task allocation in advance, ensure the smooth progress of high-priority construction tasks, and avoid affecting the progress and quality of the construction project.

[0145] In some embodiments, in response to a mismatch between the time-series heatmap and the task temperature conditions of a priority task, the processor may adjust the dispatched tasks; update the time-series heatmap based on the adjusted dispatched tasks; and match and dispatch priority tasks based on the updated time-series heatmap and the task temperature conditions of the priority tasks.

[0146] In some embodiments, when the temperature zone in the time-series heatmap cannot match the task temperature conditions of a priority task, the processor can adjust the assigned tasks. Adjustments include, but are not limited to, adjusting the execution order of assigned tasks, canceling assigned tasks with lower priority, changing the construction area corresponding to an assigned task, or any combination thereof.

[0147] In some embodiments, the processor may redetermine the impact of the adjusted dispatched tasks on the distribution of the first heat source based on the adjusted dispatched tasks, and redetermine and update the time-series heat map based on the impact of the adjusted dispatched tasks on the distribution of the first heat source by using the method for determining the time-series heat map as described above.

[0148] In some embodiments, the processor determines the target construction personnel corresponding to the priority task by matching multiple temperature zones in the updated time-series heat map with the task temperature conditions of the priority task in the same way as determining the target construction personnel, and dispatches the priority task to the target construction personnel.

[0149] In some embodiments, the processor dispatches the priority task in response to a match between the time-series heatmap and the task temperature conditions of the priority task. Otherwise, the processor repeats the steps of adjusting the dispatched tasks, updating the time-series heatmap, and matching and dispatching priority tasks until the time-series heatmap matches the task temperature conditions of the priority task, and then dispatches the priority task.

[0150] In some embodiments of this specification, by adjusting the assigned construction tasks, updating the time-series heat map, and re-matching and assigning priority tasks based on the updated time-series heat map, it can be ensured that priority tasks can be executed smoothly under suitable temperature conditions.

[0151] In some embodiments, the processor can determine the second heat source distribution based on the currently executing dispatched task, determine the abnormal heat source region based on the first and second heat source distributions, and obtain the investigation results of the abnormal heat source region. For more information on anomaly investigation, see [link to relevant documentation]. Figure 4 And related explanations.

[0152] In some embodiments of this specification, matching tasks to be assigned and target construction personnel are selected based on temperature zones and task temperature conditions on a temperature heat map. This avoids blind task allocation, enables construction personnel to work in suitable temperatures, thereby preventing heatstroke and ensuring the health of construction personnel and the smooth progress of construction tasks.

[0153] Figure 4 This is an exemplary flowchart illustrating troubleshooting based on some embodiments of this specification. Figure 4As shown, process 400 includes the following steps. In some embodiments, process 400 may be executed by a processor.

[0154] Step 410: Determine the distribution of the second heat source based on the ongoing construction tasks.

[0155] The distribution of secondary heat sources refers to the distribution of heat sources generated by the execution of construction tasks. This distribution includes the construction area where the heat sources are located.

[0156] In some embodiments, the processor can determine whether a construction task that is being executed will generate a heat source by querying a fourth preset table based on the construction task being executed, and then determine the construction area corresponding to the construction task that generates the heat source, thereby obtaining a second heat source distribution.

[0157] The fourth preset table includes the correspondence between construction task items and whether a heat source is generated. The fourth preset table can be set based on experience.

[0158] Step 420: Based on the distribution of the first and second heat sources, determine the abnormal heat source areas.

[0159] For more information on the distribution of the first heat source, please refer to the relevant instructions in step 230.

[0160] An abnormal heat source area refers to a construction area where a heat source exists in the first heat source distribution but not in the second heat source distribution.

[0161] 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 area where these heat sources are located as heat source abnormal areas, and the remaining areas as heat source normal areas.

[0162] Step 430: Obtain the investigation results of the abnormal heat source area.

[0163] Anomaly investigation refers to the inspection and analysis of areas with abnormal heat sources in order to determine the nature and cause of the abnormal heat sources.

[0164] The investigation results refer to the findings of an investigation into areas with abnormal heat sources. The investigation results include both normal and abnormal findings.

[0165] In some embodiments, safety officers can conduct anomaly investigations through methods such as manual on-site inspections, retrieving image data of the abnormal heat source area, and retrieving operational data of equipment in the abnormal heat source area. The investigation results are then input into the memory via a user terminal. The processor retrieves the investigation results of the abnormal heat source area stored in the memory.

[0166] In some embodiments, when safety officers conduct on-site inspections, they can directly address faults or potential hazards that can be resolved directly, and input the results into a memory.

[0167] Step 441: In response to the investigation result being normal, determine the temperature heat map based on the distribution of the first heat source.

[0168] The investigation results were normal, indicating that the heat source in the abnormal heat source area was generated by the normal operation of lighting equipment and production equipment during the construction process, and would not affect the construction.

[0169] In some embodiments, in response to a normal investigation result, the processor can determine a temperature heat map based on the distribution of the first heat source.

[0170] For more information on how to determine the temperature heat map, see the relevant instructions in step 230.

[0171] Step 442: In response to the abnormal investigation result, determine the temperature heat map based on the distribution of the second heat source.

[0172] An anomaly in the investigation result indicates potential equipment malfunction, fire hazards, or other safety risks in the area with the abnormal heat source. An anomaly also suggests that the distribution of the first heat source, determined based on the heat source type and location information at the construction site, may be unreliable, leading to an inaccurate temperature heat map based on this distribution. The processor can determine the temperature heat map based on the distribution of a second heat source. For example, the processor can determine the heat source type and duration of the second heat source corresponding to the abnormal heat source area. Based on this information, the processor can query and identify similar second heat sources in the normal heat source area, and designate the first heat source corresponding to this similar second heat source as the reference first heat source for the abnormal heat source area. The processor can then replace the original first heat source in the abnormal heat source area with the reference first heat source, re-determine the distribution of the first heat source, and thus determine the temperature heat map.

[0173] In some embodiments, in response to an abnormal investigation result, the processor can issue an early warning for areas with abnormal heat sources in various ways. For example, the processor can alert construction workers around the area with an audible and visual warning, notify management personnel via SMS, or display the early warning information for the area with abnormal heat sources on the interface of the task dispatch system.

[0174] In some embodiments of this specification, by comparing and analyzing the distributions of the first and second heat sources, abnormal heat source areas can be identified in a timely manner, and investigations can be conducted to determine the investigation results. When the investigation result is normal, the temperature heat map is updated by real-time data collection of the first heat source distribution, accurately reflecting the real-time thermal field distribution at the construction site. When the investigation result is abnormal, potential safety hazards can be addressed promptly, ensuring the safety of the construction site.
