Description

Technical Field

[0001] The present application relates to the field of engineering management technology, and specifically to a method, device, medium and equipment for on-site safety management of an engineering construction project group. Background Art

[0002] Engineering construction projects refer to projects that use engineering construction as a carrier. They are one-time engineering construction tasks that are managed objects. They mainly use buildings or structures as target outputs. They need to pay a certain fee, follow certain procedures, and be completed within a certain period of time, and they should meet relevant quality requirements. An engineering construction project group can be understood as a collection of multiple engineering construction projects that are being built at the same time. It is an integrated management model that achieves resource sharing and unified management by coordinating multiple related projects, thereby achieving overall strategic goals. Among them, the engineering construction project can be the Yangtze River Protection Project. The Yangtze River Protection Project mainly focuses on protecting and improving the environmental quality of the Yangtze River Basin. It includes but is not limited to construction projects such as pollution treatment, ecological restoration, and water resource protection, thereby reducing pollution, protecting the ecology, and ensuring the safety and sustainable use of the Yangtze River, an important water resource. Among them, the on-site safety management of the engineering construction project group is of great significance to the construction safety of each engineering construction project.

[0003] At present, the method usually adopted for on-site safety management of engineering construction project groups is: based on the personal safety inspection experience of safety inspectors, determine the reasonable frequency of safety inspections at various engineering construction projects, and finally conduct safety inspections on engineering construction projects according to the determined frequency, so as to reduce the safety risks at the engineering construction project sites. However, under this method, the safety inspection experience requirements for safety inspectors are relatively high, which makes it difficult to reduce the safety risks of engineering construction projects. Summary of the invention

[0004] In order to reduce the difficulty of reducing safety risks in engineering construction projects, the present application provides a method, device, medium and equipment for on-site safety management of an engineering construction project group.

[0005] In a first aspect of the present application, a method for on-site safety management of an engineering construction project group is provided, which specifically includes: Obtain key hazardous operations in the target engineering construction project, and determine the potential hidden dangers on site corresponding to each key hazardous operation, wherein the key hazardous operation is an operation that is prone to safety accidents, and the potential hidden dangers on site are potential hidden dangers on site that are prone to induce safety accidents during the corresponding key hazardous operation; Conducting an inspection of the construction site of at least one associated engineering construction project by a first drone to determine a first actual on-site hidden danger, and determining a target inspection order of each of the key dangerous operations in the target engineering construction project by a second drone based on the first actual on-site hidden danger and the prone on-site hidden danger, the project progress of the associated engineering construction project and the target engineering construction project being within the same progress range and of the same project type, and the project progress of the associated engineering construction project being greater than the project progress of the target engineering construction project; In accordance with the target inspection sequence, the target engineering construction project is inspected by the second UAV to obtain the second actual on-site hidden dangers of each of the key dangerous operations, and the safety risk value of the target engineering construction project is determined according to the second actual on-site hidden dangers; Based on the safety risk value, the inspection frequency of the target engineering construction project is determined, and the inspection frequency is sent to the terminal of the safety inspector of the target engineering construction project. The larger the safety risk value, the higher the corresponding inspection frequency.

[0006] By adopting the above technical solution, after obtaining the key dangerous operations and the corresponding on-site hidden dangers that are prone to occur, the first UAV is then used to conduct hidden danger inspections on the project progress that exceeds the project progress of the target engineering construction project, is close to the project progress of the target engineering construction project, and has the same project type as the related engineering construction projects, so as to obtain the first actual on-site hidden dangers that are of reference significance for the hidden danger investigation of the target engineering construction project with a later project progress. Then, combined with the first actual on-site hidden dangers and the prone on-site hidden dangers, an analysis is performed to determine the target inspection sequence of the second UAV, thereby improving the efficiency of the hidden danger investigation and the effect of avoiding safety accidents. Further, after the inspection is carried out in accordance with the target inspection sequence, the on-site hidden dangers that actually occur in each key dangerous operation of the target engineering construction project, namely, the second actual on-site hidden dangers, are determined. Based on the analysis of each second actual on-site hidden danger, the safety risk value of the entire target engineering construction project is determined, thereby accurately assessing the risk of safety accidents occurring in the target engineering construction project. Finally, based on the safety risk value, the inspection frequency of the target engineering construction project is reasonably determined, getting rid of the dependence on the experience of personnel, and reducing the difficulty of reducing the safety risk of the engineering construction project.

[0007] Optionally, the step of obtaining key hazardous operations in the target engineering construction project and determining the potential on-site hazards corresponding to each key hazardous operation specifically includes: Obtaining construction operations in which safety accidents occurred during the historical construction of the target engineering construction project, counting the first occurrence times of each construction operation, and selecting the construction operation with the first occurrence times from each construction operation in descending order as the key dangerous operation; The second number of occurrences of hidden dangers that may cause safety accidents in each of the key dangerous operations is counted, and the hidden dangers that may cause safety accidents are selected from the second number of hidden dangers that may cause safety accidents in descending order as the hidden dangers that are likely to occur.

[0008] By adopting the above technical scheme, the greater the number of first occurrences, the more likely a safety accident will occur in the corresponding construction operation, thereby determining the key dangerous operations of the target engineering construction project; further, the greater the number of second occurrences, the more likely the corresponding induced on-site hidden danger will lead to the occurrence of a safety accident, and finally the induced on-site hidden danger with the second number is selected from various induced on-site hidden dangers to be determined as the prone on-site hidden danger, thereby facilitating the subsequent safety risk assessment of the target engineering construction project.

[0009] Optionally, determining the target inspection order of the second unmanned aerial vehicle for each of the key dangerous operations in the target engineering construction project based on the first actual on-site hidden dangers and the prone on-site hidden dangers specifically includes: Counting the number of occurrences of each of the first actual on-site hidden dangers, and selecting the third number of first actual on-site hidden dangers from each of the first actual on-site hidden dangers in descending order of the number of occurrences and determining them as key actual on-site hidden dangers; Determine the key dangerous operations that have the key actual on-site hidden dangers among the corresponding on-site hidden dangers that are prone to occur as target dangerous operations, and calculate the first weight of each of the key dangerous operations and the second weight of the corresponding on-site hidden dangers that are prone to occur, the first weight being the ratio of the first occurrence number of each of the key dangerous operations to the sum of the first occurrence numbers of all the key dangerous operations, and the second weight being the ratio of the second occurrence number of a single on-site hidden danger that is prone to occur corresponding to the key dangerous operation to the sum of the second occurrence numbers of all the corresponding on-site hidden dangers that are prone to occur; Calculate the sum of the first weight products of each of the target dangerous operations and the second weight of the corresponding key actual on-site hidden dangers, and determine the target inspection order of the corresponding target dangerous operations according to the sum of the first weight products. The larger the sum of the first weight products, the higher the corresponding target inspection order. Calculate the sum of the first weights of the remaining key dangerous operations except the target dangerous operations and the second weight products of the corresponding second weights that are prone to on-site hidden dangers, and determine the target inspection order of the corresponding remaining key dangerous operations based on the sum of the second weight products. The larger the sum of the second weight products, the earlier the corresponding target inspection order, and the target inspection order of the target dangerous operations precedes the target inspection order of the remaining key dangerous operations.

[0010] By adopting the above technical solution, the target inspection order of the corresponding target dangerous operation is determined according to the sum of the first weight products. The larger the sum of the first weight products, the greater the risk of safety accidents due to the first actual on-site hidden dangers in the target engineering construction project as the project progresses, the higher the corresponding target inspection order, the higher the priority of the inspection, and the efficiency of hidden danger investigation and the effect of avoiding the risk of accidents. Furthermore, the larger the sum of the second weight products, the greater the risk of safety accidents in the corresponding remaining key dangerous operations, and then the target inspection order of each remaining key dangerous operation is determined, and finally not only the key dangerous operations with greater safety accident risks can be inspected first, but also the key dangerous operations that are prone to safety accidents due to the first actual on-site hidden dangers as the project progresses can be inspected first, which can better ensure the efficiency of hidden danger investigation and the effect of avoiding safety accidents.

[0011] Optionally, determining the safety risk value of the target engineering construction project according to the second actual on-site hidden danger specifically includes: Determine a third weight of each of the key dangerous operations and a fourth weight of the corresponding second actual on-site hidden danger, wherein the third weight is a ratio of the first occurrence number of each of the key dangerous operations to the sum of the first occurrence numbers of all the key dangerous operations, and the fourth weight is a ratio of the second occurrence number of the second actual on-site hidden danger corresponding to the key dangerous operation to the sum of the second occurrence numbers of all the corresponding induced on-site hidden dangers; Calculate the sum of the weight products of the third weight of each of the key dangerous operations and the fourth weight of each of the corresponding second actual on-site hidden dangers, and sum the sums of the weight products to obtain the safety risk coefficient corresponding to the target engineering construction project; Substitute the safety risk coefficient into the preset safety risk value calculation formula to obtain the corresponding safety risk value.

[0012] By adopting the above technical solution, the weight product of the third weight of each key dangerous operation and the corresponding fourth weight of each second actual on-site hidden danger is calculated and summed up to obtain the sum of the weight products corresponding to a single key dangerous operation, and then the sum of the weight products is summed up to obtain the safety risk coefficient corresponding to the target engineering construction project, thereby preliminarily reflecting the overall risk of accidents in the target engineering construction project. Finally, this safety risk coefficient is substituted into the preset safety risk value calculation formula to obtain the corresponding safety risk value, thereby more accurately representing the overall risk of accidents in the target engineering construction project.

[0013] Optionally, the security risk value calculation formula is: ; Where V represents the safety risk value of the target engineering construction project, S represents the safety risk coefficient of the target engineering construction project, and Fmost Indicates the number of recent safety accidents of the target construction project within the preset time before the current time, F total represents the total number of safety accidents during the construction of the target engineering project, T represents the duration corresponding to the preset time, It represents the adjustment parameter, which adjusts the impact of the number of recent safety accidents on the current safety risk value of the target engineering construction project. It represents the adjustment parameter, which adjusts the impact of the total number of safety accidents on the current safety risk value of the target engineering construction project. The scaling parameter that represents the impact of the total number of safety accidents on the current safety risk value of the target engineering construction project, Indicates the severity level of the i-th most recent safety accident of the target construction project within the preset time before the current time. represents the weight of the i-th most recent safety accident, It represents the time difference between the occurrence time of the i-th most recent safety accident and the current time.

[0014] By adopting the above technical solution, Indicates the frequency of safety accidents in the target engineering construction project within the preset time, 1+ The role is to reduce the impact of the low frequency of recent accidents on V calculation, It represents the cumulative effect of accidents that occurred in the target construction project since its construction. The logarithm of can effectively avoid the excessive impact of the total number of safety accidents on the calculation of V, so that the determined safety risk value is more accurate. The role is to reduce The impact on V calculation when it is too low. Among them, It is used to scale the impact of the total number of safety accidents on V, to avoid the total number of safety accidents causing V to rise nonlinearly. In addition, represents the severity of the i-th most recent safety accident, It indicates the warning degree of the i-th recent safety accident to the current construction of the target engineering project, The larger it is, the higher the warning level is, the stronger the personnel's awareness of avoiding potential safety hazards is, and the lower the overall safety risk of the target engineering construction project is. The smaller it is, the closer the occurrence of the i-th most recent safety accident is to the current time, the higher the warning level is, the stronger the personnel's awareness of avoiding safety hazards is, and the lower the overall safety risk of the target engineering construction project is. The warning levels of all recent safety accidents within a preset time are accumulated to represent the overall warning level of recent safety accidents. As the denominator, the warning level of recent safety accidents can be reasonably incorporated into the calculation of the safety risk value, thereby improving the accuracy of the safety risk value.

[0015] Optionally, the method further includes: The progress range corresponding to the target engineering construction project is determined as the target progress range, and key related engineering construction projects whose project progress is less than that of the target engineering construction project are screened out from the uninspected related engineering construction projects of the target engineering construction project, wherein the uninspected related engineering construction projects are engineering construction projects whose project progress is within the target progress range and are of the same project type as the target engineering construction project and have not yet been inspected; Determine, from among the key related engineering construction projects, a target related engineering construction project having the smallest progress gap with the target engineering construction project; According to the sum of the weight products, the initial inspection order of the corresponding key dangerous operations is determined, and based on the initial inspection order, the first UAV corresponding to the target-related engineering construction project is used to perform on-site hidden danger inspections on the corresponding key dangerous operations. The larger the sum of the weight products, the higher the corresponding initial inspection order.

[0016] By adopting the above technical solution, the initial inspection order of the corresponding key dangerous operations is determined according to the sum of the weight products. The larger the sum of the weight products, the more likely the corresponding key dangerous operations are to cause safety accidents when the corresponding second actual site hidden dangers appear, and the higher the corresponding initial inspection order. Finally, the first drone corresponding to the target-related engineering construction project is controlled to inspect the key dangerous operations in the target-related engineering construction project, thereby improving the hidden danger detection efficiency and safety risk avoidance effect of the target-related engineering construction project that has not been inspected.

[0017] Optionally, the method further includes: Determine the first actual site hidden danger that does not exist in the second actual site hidden danger of each of the key dangerous operations as a reference site hidden danger; The hidden danger prevention plan of the target construction project for the hidden danger of the reference site is sent to the terminal of the safety personnel corresponding to the associated engineering construction project.

[0018] By adopting the above technical solution, the reference site hidden dangers are determined, that is, the site hidden dangers that are easy to occur in the associated engineering construction projects with fast project progress but do not appear in the target engineering construction project with slow project progress, which means that the prevention measures of the target engineering construction project for this reference site hidden danger are more effective. Then, the hidden danger prevention plan of this target engineering construction project for this reference site hidden danger is sent to the terminal of the safety personnel corresponding to the associated engineering construction project, so that the hidden danger prevention plan of the associated engineering construction project can be effectively optimized and the probability of occurrence of reference site hidden dangers can be reduced.

[0019] In a second aspect of the present application, a construction project site safety management device is provided, which specifically includes: An information acquisition module is used to acquire key dangerous operations in the target engineering construction project, and determine the on-site hidden dangers that are prone to occur corresponding to each of the key dangerous operations, wherein the key dangerous operations are operations that are prone to safety accidents, and the on-site hidden dangers that are prone to occur are on-site hidden dangers that are prone to induce safety accidents during the corresponding key dangerous operations; A sequence determination module is used to inspect the construction site of at least one related engineering construction project by a first drone, determine a first actual site hidden danger, and determine a target inspection sequence of each of the key dangerous operations in the target engineering construction project by a second drone based on the first actual site hidden danger and the prone site hidden danger, the project progress of the related engineering construction project and the target engineering construction project are within the same progress range and are of the same project type, and the project progress of the related engineering construction project is greater than the project progress of the target engineering construction project; a hidden danger inspection module, configured to inspect the target engineering construction project through the second unmanned aerial vehicle according to the target inspection sequence, obtain the second actual on-site hidden danger of each of the key dangerous operations, and determine the safety risk value of the target engineering construction project according to the second actual on-site hidden danger; The on-site management module is used to determine the inspection frequency of the target engineering construction project based on the safety risk value, and send the inspection frequency to the terminal of the safety inspector of the target engineering construction project. The larger the safety risk value, the higher the corresponding inspection frequency.

[0020] By adopting the above technical solution, the information acquisition module obtains key dangerous operations and determines the potential hazards on site corresponding to each key dangerous operation. The sequence determination module determines the target inspection sequence of the second UAV for each key dangerous operation in the target engineering construction project. Then the hidden danger inspection module inspects the target engineering construction project through the second UAV according to the target inspection sequence, and then determines the safety risk value of the target engineering construction project. Finally, the site management module determines the inspection frequency and sends the inspection frequency to the terminal of the safety inspector.

[0021] In a third aspect of the present application, a computer-readable storage medium is provided, in which a computer program is stored. When the computer program is loaded and executed by a processor, the method steps described in any one of the first aspects are performed.

[0022] In a fourth aspect of the present application, an electronic device is provided, specifically comprising: A processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein the processor is used to load and execute the computer program stored in the memory so that the electronic device performs the method as described in any one of the first aspects.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: a first actual on-site hidden danger is obtained through a first drone, which is of reference significance for the hidden danger investigation of a target engineering construction project with a lagging project schedule. Then, the first actual on-site hidden danger and the on-site hidden danger that is prone to occur are analyzed to determine the target inspection sequence of the second drone, thereby improving the efficiency of hidden danger investigation and the effect of avoiding safety accidents. Furthermore, after inspections are carried out in accordance with the target inspection sequence, the on-site hidden dangers that actually occur in each key dangerous operation of the target engineering construction project, namely, the second actual on-site hidden dangers, are determined. Based on the analysis of each second actual on-site hidden danger, the safety risk value of the entire target engineering construction project is determined, thereby accurately assessing the risk of safety accidents occurring in the target engineering construction project. Finally, based on the safety risk value, the inspection frequency of the target engineering construction project is reasonably determined, getting rid of the reliance on the experience of personnel, and achieving the difficulty of reducing the safety risks of engineering construction projects.

[0029] See also Figure 1 The present application embodiment discloses a flow chart of a method for on-site safety management of a construction project group, which can be implemented by a computer program or run on an on-site safety management device for a construction project group based on the von Neumann system. The computer program can be integrated into an application or run as an independent tool application, specifically including: S101: Obtain key hazardous operations in the target engineering construction project, and determine the potential on-site hazards corresponding to each key hazardous operation.

[0030] Specifically, in an embodiment of the present application, the target engineering construction project refers to an engineering construction project in the engineering construction project group that is prepared for hidden danger inspection. The engineering construction project is a Yangtze River protection project, which can be an integrated urban and rural sewage treatment project or a water environment comprehensive improvement project, etc. In other embodiments, the engineering construction project can also be an urban construction project. Key dangerous operations are operations that are prone to safety accidents, and prone to on-site hidden dangers are on-site hidden dangers that are prone to induce safety accidents during the corresponding key dangerous operations. Furthermore, key dangerous operations include but are not limited to deep excavation of underground pipelines, scaffolding projects, large-scale lifting, and deep foundation pit projects involved in the construction process of the target engineering construction project. In addition, on-site hidden dangers include but are not limited to construction personnel not wearing safety helmets, improper operation of mechanical equipment, etc.

[0031] Furthermore, the embodiment of the present application discloses a method for on-site safety management of a group of engineering construction projects, the executor of which is a server. The server can be an independent physical server, or a server cluster or a distributed system composed of multiple physical servers. The server and the drone are wirelessly connected through a wireless network so that the two can interact. In the embodiment of the present application, the drone is an engineering inspection drone, which is used to conduct all-round monitoring and safety hazard inspection of the construction site of the engineering construction project. Such drones are equipped with high-definition cameras and sensors, which can shoot the construction site from different angles and promptly discover and record safety hazards.

[0032] Furthermore, a feasible way to obtain key dangerous operations and corresponding hidden dangers that are prone to occur on site is: from the start of construction of the target engineering construction project to the current electronic archive of the construction log, obtain the construction operations in which safety accidents have occurred during the construction process, and then count the first occurrence times of each construction operation. The larger the first occurrence times, the more likely it is that a safety accident will occur in the corresponding construction operation, and select the first number of construction operations from each construction operation in order of the first occurrence times from large to small to determine as the key dangerous operation. Further, from the electronic archive of the construction log, count the second occurrence times of the induced hidden dangers on site corresponding to the safety accidents that have occurred in a single key dangerous operation, that is, the hidden dangers on site that cause safety accidents. The larger the second occurrence times, the more likely the corresponding hidden dangers on site are to cause safety accidents. Finally, select the second number of hidden dangers on site from each hidden danger on site to determine as the hidden dangers on site that are prone to occur.

[0033] S102: inspecting the construction site of at least one related engineering construction project by a first drone to determine first actual on-site hidden dangers, and determining a target inspection order of each key dangerous operation in the target engineering construction project by a second drone based on the first actual on-site hidden dangers and the on-site hidden dangers that are likely to occur.

[0034] Specifically, the project progress of the associated engineering construction project and the target engineering construction project are within the same progress range and the project type is the same, indicating that the progress of the target engineering construction project in the engineering construction project group is relatively close to that of the associated engineering construction project and belongs to the same level. The project progress of the associated engineering construction project is greater than the project progress of the target engineering construction project, indicating that the construction progress of the associated engineering construction project is slightly faster than that of the target engineering construction project. Among them, the project progress refers to the completion progress of the engineering construction project from the start of construction to the present. In the embodiment of the present application, the project progress can be expressed as a percentage. Exemplarily, the project progress can be 80%. Project type refers to the type divided according to the nature or purpose of the engineering construction project. Exemplarily, the associated engineering construction project is a comprehensive water environment management project in City A, and the target engineering construction project is a comprehensive water environment management project in City B. Then the project types of the two are the same, both of which are water environment management types. In other embodiments, the associated engineering construction project is also the engineering construction project of the same project type as the target engineering construction project, and the engineering construction project with the closest project progress to the target engineering construction project. It should be noted that each engineering construction project in the engineering construction project group is preset with a drone at the construction site for taking off at any time to check for safety hazards. It should be noted that different progress ranges represent different progress levels of engineering construction projects. For example, a progress range of: 0%~40% indicates that the project is in the early stages; 40%~60% indicates that the project is in the middle stages; and 60%~100% indicates that the project is in the final stages.

[0035] Furthermore, the first drone corresponding to each associated engineering construction project is controlled to conduct a safety hazard inspection on the construction site of the corresponding associated engineering construction project to obtain at least one first actual on-site hazard. The specific process of the inspection is: the first drone is used to conduct real-time video monitoring of each operating area in the construction site of the associated engineering construction project. After the server obtains the monitoring video, it uses the hazard identification model to identify the on-site hazards therein, and finally obtains the corresponding first actual on-site hazard. Among them, the hazard identification model can be a trained convolutional neural network model, and in other embodiments, it can also be a recurrent neural network model. The training process is: the model is trained with monitoring video clips marked with on-site hazards until the model converges.

[0036] Furthermore, the number of occurrences of each type of first actual on-site hidden danger is counted; the greater the number of occurrences, the more likely the corresponding first actual on-site hidden danger is to occur in the construction work of an associated engineering construction project whose project progress is ahead of the target engineering construction project; then, in order of the number of occurrences from largest to smallest, the third number of first actual on-site hidden dangers is selected from each first actual on-site hidden danger, and determined as a key actual on-site hidden danger, that is, it is more likely to occur in the construction work of an associated engineering construction project whose project progress is ahead of the target engineering construction project; further, as the project progress of the target engineering construction project advances, this key actual on-site hidden danger is also likely to occur.

[0037] Further, the key dangerous operation that has this key actual on-site hidden danger among the corresponding prone on-site hidden dangers is determined as the target dangerous operation. At the same time, the first weight of each key dangerous operation and the second weight of the corresponding prone on-site hidden danger are calculated. The first weight is the ratio of the first occurrence number of each key dangerous operation to the sum of the first occurrence numbers of all key dangerous operations, and the second weight is the ratio of the second occurrence number of a single prone on-site hidden danger corresponding to the key dangerous operation to the sum of the second occurrence numbers of all prone on-site hidden dangers. Further, the first weight of a single target dangerous operation is calculated and the first weight product of the second weight of the corresponding at least one key actual on-site hidden danger is summed to obtain the sum of the first weight products. The larger the first weight product, the greater the possibility that the target dangerous operation will have a safety accident due to the corresponding key actual on-site hidden danger. The larger the sum of the first weight products, the greater the possibility that the target dangerous operation will have a safety accident due to the first actual on-site hidden danger. Furthermore, according to the sum of the first weight products, the target inspection order of the corresponding target dangerous operations is determined. The larger the sum of the first weight products is, the greater the risk of safety accidents occurring in the target engineering construction project due to the first actual on-site hidden dangers as the project progresses. The earlier the corresponding target inspection order is, the higher the inspection priority is, thereby improving the efficiency of hidden danger detection and the avoidance of accident risks.

[0038] Furthermore, the key dangerous operations other than the target dangerous operations in the various key dangerous operations of the target engineering construction project are determined as the remaining key dangerous operations, and there are no key actual on-site hidden dangers in the corresponding on-site hidden dangers. The first weight of a single remaining key dangerous operation is multiplied by the second weight product of the corresponding second weights of each on-site hidden danger, and the sum is calculated to obtain the corresponding sum of the second weight products. The larger the sum of the second weight products, the greater the risk of safety accidents in the corresponding remaining key dangerous operations. Furthermore, according to the sum of the second weight products, the target inspection order of the corresponding remaining key dangerous operations is determined. The larger the sum of the second weight products, the higher the corresponding target inspection order, and the target inspection order of each target dangerous operation precedes the target inspection order of each remaining key dangerous operation. Finally, the target inspection order of the second UAV for inspecting each key dangerous operation in the target engineering construction project is determined, so that when the subsequent second UAV inspects according to this target inspection order, it can not only give priority to the inspection of key dangerous operations with higher risks of safety accidents, but also give priority to the inspection of key dangerous operations that may cause safety accidents due to the first actual on-site hidden dangers that are prone to occur as the project progresses, thereby better ensuring the efficiency of hidden danger detection and the effect of safety accident avoidance.

[0039] S103: In accordance with the target inspection sequence, the target engineering construction project is inspected by a second UAV to obtain a second actual on-site hidden danger of each key dangerous operation, and the safety risk value of the target engineering construction project is determined based on the second actual on-site hidden danger.

[0040] Specifically, according to the determined target inspection sequence, the location information of each key dangerous operation is sent to the preset second UAV, and the second UAV is controlled to conduct safety hazard inspections on the corresponding key dangerous operations according to the target inspection sequence to obtain the second actual on-site hazard of each key dangerous operation.

[0041] Further, according to each second actual on-site hidden danger, the safety risk value of the target engineering construction project is determined. The higher the safety risk value, the higher the overall risk of a safety accident in the target engineering construction project. A feasible implementation method is to determine the third weight of each key dangerous operation and the fourth weight of the corresponding second actual on-site hidden danger, the third weight is the ratio of the first occurrence number of each key dangerous operation to the sum of the first occurrence number of all key dangerous operations, and the fourth weight is the ratio of the second occurrence number of the second actual on-site hidden danger corresponding to the key dangerous operation (the number of occurrences in the past construction of the target engineering construction project) to the sum of the second occurrence number of all corresponding induced on-site hidden dangers. Further, the weight product of the third weight of each key dangerous operation and the fourth weight of each corresponding second actual on-site hidden danger is calculated and summed to obtain the sum of the weight products corresponding to a single key dangerous operation, and then the sum of the weight products is summed to obtain the safety risk coefficient corresponding to the target engineering construction project, thereby preliminarily reflecting the risk of an accident in the target engineering construction project as a whole.

[0042] Finally, this safety risk coefficient is substituted into the preset safety risk value calculation formula to obtain the corresponding safety risk value, thereby more accurately representing the safety risk of accidents in the target engineering construction project as a whole. The larger the safety risk value, the higher the safety risk. Among them, the safety risk value calculation formula is: ; Where V represents the safety risk value of the target engineering construction project, S represents the safety risk coefficient of the target engineering construction project, and F most Indicates the number of recent safety accidents of the target construction project within the preset time before the current time, F total represents the total number of safety accidents during the construction of the target engineering project, T represents the duration corresponding to the preset time, It represents the adjustment parameter, which adjusts the impact of the number of recent safety accidents on the current safety risk value of the target engineering construction project. It represents the adjustment parameter, which adjusts the impact of the total number of safety accidents on the current safety risk value of the target engineering construction project. The scaling parameter that represents the impact of the total number of safety accidents on the current safety risk value of the target engineering construction project, Indicates the severity level of the i-th most recent safety accident of the target construction project within the preset time before the current time. represents the weight of the i-th most recent safety accident, It represents the time difference between the occurrence time of the i-th most recent safety accident and the current time, and i represents the i-th most recent safety accident.

[0043] It should be noted that Indicates the frequency of safety accidents in the target engineering construction project within the preset time, 1+ The role is to reduce the impact of the low frequency of recent accidents on V calculation, It represents the cumulative effect of accidents that occurred in the target construction project since its construction. The logarithm of can effectively avoid the excessive impact of the total number of safety accidents on the calculation of V, so that the determined safety risk value is more accurate. The role is to reduce The impact on V calculation when it is too low. Among them, It is used to scale the impact of the total number of safety accidents on V, to avoid the total number of safety accidents causing V to rise nonlinearly. In addition, represents the severity of the i-th most recent safety accident, It indicates the warning degree of the i-th recent safety accident to the current construction of the target engineering project, The larger it is, the higher the warning level is, the stronger the personnel's awareness of avoiding potential safety hazards is, and the lower the overall safety risk of the target engineering construction project is. The smaller it is, the closer the occurrence of the i-th most recent safety accident is to the current time, the higher the warning level is, the stronger the personnel's awareness of avoiding safety hazards is, and the lower the overall safety risk of the target engineering construction project is. The warning levels of all recent safety accidents within a preset time are accumulated to represent the overall warning level of recent safety accidents. As the denominator, the warning level of recent safety accidents can be reasonably incorporated into the calculation of the safety risk value, thereby improving the accuracy of the safety risk value.

[0044] In addition, a feasible way to determine the severity level of a recent safety accident is to count the number of injured people in each recent safety accident, with the severity level ranging from 0 to 1, and determine the corresponding severity level of the recent safety accident based on the number of injured people. If the number of injured people is 10 or more, the risk factor is set to 1; if the number of injured people is 9, the risk factor is set to 0.9, and so on. The more the number of injured people, the higher the severity level and the more serious the recent safety accident.

[0045] In other embodiments, the progress range corresponding to the target engineering construction project, that is, the progress range where the project progress of the target engineering construction project is located, is determined as the target progress range, and the key related engineering construction projects whose project progress is less than the target engineering construction project, that is, the project progress is slower than the target engineering construction project, are screened out from the uninspected related engineering construction projects of the target engineering construction project, wherein the uninspected related engineering construction projects are engineering construction projects whose project progress is within the target progress range and are of the same project type as the target engineering construction project and have not yet been inspected. Then, the progress difference between the project progress of the target engineering construction project and the project progress of each key related engineering construction project is calculated, and the key related engineering construction project corresponding to the smallest progress difference is determined as the target related engineering construction project, that is, the engineering construction project whose project progress is later than the target engineering construction project and is relatively close to the project progress of the target engineering construction project. The second actual on-site hidden danger found out by the current inspection of the target engineering construction project is likely to occur with the progress of the target related engineering construction project.

[0046] Furthermore, the initial inspection order of the corresponding key dangerous operations is determined according to the sum of the weight products. The larger the sum of the weight products, the more likely the corresponding key dangerous operations will cause safety accidents when the corresponding second actual on-site hidden dangers appear, and the higher the corresponding initial inspection order. Finally, the first drone corresponding to the target-related engineering construction project is controlled to inspect the key dangerous operations in the target-related engineering construction project, thereby improving the hidden danger detection efficiency and safety risk avoidance effect of the target-related engineering construction project that has not been inspected. It should be noted that the project progress is specifically input by the project leader of the corresponding engineering construction project through a terminal, which can be a smart phone or a personal computer.

[0047] S104: Based on the safety risk value, determine the inspection frequency of the target engineering construction project, and send the inspection frequency to the terminal of the safety inspector of the target engineering construction project. The larger the safety risk value, the higher the corresponding inspection frequency.

[0048] Specifically, after the safety risk value is determined, the inspection frequency of the target engineering construction project is determined through the preset frequency matching table, that is, the safety inspection frequency of the target engineering construction project by the safety inspectors. The larger the safety risk value, the higher the corresponding inspection frequency. The frequency matching table includes different safety risk value ranges and corresponding inspection frequencies. For example, the frequency matching table includes a safety risk value range of 0 to 2, and the corresponding inspection frequency is once in three months; a safety risk value range of 2 to 4, and the corresponding inspection frequency is twice in three months; a safety risk value range of 4 to 6, and the corresponding inspection frequency is once every two months, etc. Finally, the inspection frequency matched by the target engineering construction project is sent to the terminal of the corresponding safety inspector to achieve effective and reasonable management of the site.

[0049] See also Figure 2 The present application embodiment discloses a flowchart of another method for on-site safety management of a construction project group, which can be implemented by a computer program or run on an on-site safety management device for a construction project group based on the von Neumann system.

[0051] S203: In accordance with the target inspection sequence, the target engineering construction project is inspected by a second UAV to obtain a second actual on-site hidden danger of each key dangerous operation, and the safety risk value of the target engineering construction project is determined based on the second actual on-site hidden danger.

[0052] S204: Based on the safety risk value, determine the inspection frequency of the target engineering construction project, and send the inspection frequency to the terminal of the safety inspector of the target engineering construction project. The larger the safety risk value, the higher the corresponding inspection frequency.

[0054] S205: determining the first actual site hidden danger that does not exist in the second actual site hidden danger of each key dangerous operation as a reference site hidden danger; S206: Send the hidden danger prevention plan of the target construction project for the hidden dangers of the reference site to the terminal of the safety personnel corresponding to the associated construction project.

[0055] Specifically, determine whether there are first actual site hazards in the second actual site hazards of each key dangerous operation of the target engineering construction project, and screen out the first actual site hazards that do not exist in the second actual site hazards in all key dangerous operations, and determine them as reference site hazards, that is, site hazards that are easy to occur in associated engineering construction projects with fast project progress but do not appear in the target engineering construction projects with slow project progress, indicating that the target engineering construction project's preventive measures for this reference site hazard are more effective. Then, the hazard prevention plan for this target engineering construction project for this reference site hazard is sent to the terminal of the safety personnel corresponding to the associated engineering construction project, so that the hazard prevention plan of the associated engineering construction project is effectively optimized and the probability of occurrence of reference site hazards is reduced.

[0056] The implementation principle of the on-site safety management method for the engineering construction project group of the embodiment of the present application is: the first actual on-site hidden danger that is of reference significance for the hidden danger investigation of the target engineering construction project with a lagging project schedule is obtained through the first unmanned aerial vehicle. Then, the first actual on-site hidden danger and the on-site hidden danger that is prone to occur are analyzed to determine the target inspection sequence of the second unmanned aerial vehicle, thereby improving the efficiency of hidden danger investigation and the effect of avoiding safety accidents. Furthermore, after the inspection is carried out in accordance with the target inspection sequence, the on-site hidden dangers that actually occur in each key dangerous operation of the target engineering construction project, that is, the second actual on-site hidden dangers, are determined. Based on the analysis of each second actual on-site hidden danger, the safety risk value of the entire target engineering construction project is determined, thereby accurately assessing the risk of safety accidents occurring in the target engineering construction project. Finally, based on the safety risk value, the inspection frequency of the target engineering construction project is reasonably determined, getting rid of the dependence on the experience of personnel, and reducing the difficulty of reducing the safety risks of engineering construction projects.
