[0004] However, in the prior art, it is impossible to carry out synchronous risk prevention at the construction site according to the management and control of construction personnel and construction plans. In addition, it is impossible to conduct risk assessment based on the impact of a single operation within the construction site, nor can it conduct risk assessment on the impact of multiple operations on the construction area, reducing the management efficiency and pertinence of the construction area.

[0005] In view of the above - mentioned technical defects, a solution is now proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the above - mentioned problems and propose a construction safety risk management system adapted to water conservancy construction sites.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A construction safety risk management system adapted to water conservancy construction sites includes a construction management platform, which is communicatively connected to a personnel construction detection unit, a construction planning unit, a database, a single - operation safety detection unit, and a multi - operation safety detection unit;

[0009] The personnel construction detection unit conducts construction detection on construction personnel, collects data according to the construction operation detection results of the construction personnel, and sends it to the database for storage, which is used for job scheduling;

[0010] The construction planning unit conducts construction planning for the construction personnel at the construction site and sends the real-time construction plan to the database for storage;

[0011] The single-operation safety detection unit conducts safety detection on the single-operation construction at the construction site, collects construction parameters, and conducts construction safety analysis and detection according to the increasing or decreasing stage of the construction parameters to infer the execution risk of the single operation;

[0012] The multi-operation safety detection unit conducts safety risk assessment when multiple operations are being carried out in the construction area.

[0013] As a preferred embodiment of the present invention, the process of the personnel construction detection unit is as follows:

[0014] Set the proposition scenario and proposition, and record the filling of the construction personnel;

[0015] Mark the filled construction operations as theoretical operations; mark the actual construction operations as practical operations;

[0016] Analyze the construction operations of the construction personnel:

[0017] If the theoretical operations between adjacent tests of the construction personnel meet the operation standards and the theoretical operations are consistent with the practical operations, it is inferred that the actual execution standards are met; if the theoretical operations between adjacent tests of the construction personnel do not meet the operation standards and the theoretical operations are consistent with the practical operations, the construction operations of the construction personnel are corrected;

[0018] If the theoretical operations between adjacent tests of the construction personnel meet the operation standards and the theoretical operations are inconsistent with the practical operations, it is inferred that the practical operations of the construction personnel do not meet the actual execution standards and the theoretical operation tests are ineffective; if the theoretical operations between adjacent tests of the construction personnel do not meet the operation standards and the theoretical operations are consistent with the practical operations, it is inferred that the practical operations of the construction personnel do not meet the actual execution standards and the construction operations have not been corrected.

[0019] As a preferred embodiment of the present invention, the process of the construction planning unit is as follows:

[0020] Conduct construction planning, control the number of construction personnel for a single construction operation at the construction site to be more than one. If the current construction operation can be completed by one person, synchronously execute the adjacent operations of the current construction operation, and the construction personnel of the adjacent operations and the construction personnel of the current construction operation conduct work handover and synchronously cooperate to execute the construction operation. And when all adjacent construction operations are completed, the next construction progress can be entered; avoid the solitary operation of construction personnel at the construction site, resulting in information islands in construction operations.

[0021] As a preferred embodiment of the present invention, after determining the construction planning standards, collect the required and unnecessary conditions for construction operations; collect the required and unnecessary conditions for single-person construction operations and adjacent construction operations. If there are conflicts between the required and unnecessary conditions, mark the corresponding conditions as conflict conditions.

[0022] When there is a deviation between the intercommunication construction progress of single-person construction operations and adjacent construction operations and the actual construction progress, if the adjacent construction operation is to execute and control the conflict conditions to meet the execution requirements of the current adjacent construction operation, and the real-time progress of the single-person construction operation is not intercommunicated, then the conflict conditions are controlled to generate a risk warning signal and send the risk warning signal to the construction management platform.

[0023] As a preferred embodiment of the present invention, the process of the single-operation safety detection unit is as follows:

[0024] Unify the construction operations of a single construction machine or a single construction worker and mark them as a single operation

[0025] Collect the construction parameters of the construction area at the construction end during the single operation process;

[0026] During the process of increasing the construction parameters, according to the placement position of the transported materials in the construction area, collect the change span of the placement angle of the construction equipment when transporting materials; obtain the total increase value of the span of the construction equipment when the construction parameters in the construction area increase;

[0027] During the process of decreasing the construction parameters, collect the floating span of the levelness of the support surface in the area where the construction equipment is located, and evaluate the change of support looseness through the levelness of the support surface in the area where the construction equipment is located.

[0028] As a preferred embodiment of the present invention, if the total increase value of the span of the construction equipment when the construction parameters in the construction area increase exceeds the total span increase threshold, or the floating span of the levelness of the support surface in the area where the construction equipment is located exceeds the levelness floating span threshold, a single-operation risk signal is generated;

[0029] If the total increase value of the span of the construction equipment when the construction parameters in the construction area increase does not exceed the total span increase threshold, and the floating span of the levelness of the support surface in the area where the construction equipment is located does not exceed the levelness floating span threshold, a single-operation safety signal is generated and the single-operation safety signal is sent to the construction management platform.

[0030] As a preferred embodiment of the present invention, the process of multiple-operation safety detection units is as follows:

[0031] When multiple construction operations are carried out in the construction area, the sand excavation volume or material placement volume in the surrounding area of each construction location is collected. Taking any construction location as the center, the stress is evaluated based on the deformation of the surrounding area of the construction location. After excavation in the corresponding area, the stress in the corresponding area decreases, and vice versa, when materials are placed in the corresponding area, the stress in the corresponding area increases. According to the increase or decrease of stress, the surrounding area of the current center is marked as the increased load-bearing area and the decreased load-bearing area.

[0032] As a preferred embodiment of the present invention, when the corresponding two sides at the center position are the increased load-bearing area and the decreased load-bearing area, taking the drainage of the drainage ditch in the construction area as the area parameter, the change span value of the drainage flow rate in the construction area and the corresponding drainage ditch change path are obtained. If the increased load-bearing area is the drainage flow direction, drainage end point or passing point relative to the decreased load-bearing area; then the real-time drainage task and the real-time drainage task processing capacity of the increased load-bearing area are collected;

[0033] If the real-time drainage task and the real-time drainage task processing capacity cannot be matched at the same time, or the real-time drainage task continues to increase, it is inferred that the area parameter of the current construction area is abnormal, and area risk warning is carried out and a warning signal is sent to the construction management platform. At the same time, the construction task is re-planned according to the construction progress of the construction area, that is, when the increased load-bearing area and the decreased load-bearing area are constructed, the area parameter floating control needs to be carried out synchronously;

[0034] If the real-time drainage task and the real-time drainage task processing capacity are matched at the same time and the real-time drainage task does not continue to increase, it is inferred that the area parameter of the current construction area is normal, and area safety monitoring is carried out and a monitoring signal is sent to the construction management platform.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1. In the present invention, by comparing with the actual construction scene training and the actual construction operations of construction workers, the training efficiency of the safety awareness of construction workers is improved, avoiding the situation where the safety awareness training of construction workers is not in place and cannot achieve the appropriate efficiency, which affects the quality of construction safety risk management in the entire construction site; it should be noted that the construction safety awareness training mentioned in this technical solution is a proposition formulated for the construction scene, and the proposition processing of multiple construction workers is collected, excluding the subjective consciousness influence of each construction worker, and inferring the safety awareness training of the current construction site based on multiple data.

[0037] According to the construction plan of the entire construction staff, the construction continuity of the construction site is ensured, so that there is an adjacent operation intersection for the construction operations of the construction staff in each link, avoiding the information isolation of the construction staff, and unable to ensure the information exchange between the construction staff when performing construction operations. At the same time, when it comes to long-distance power transmission or wading, if there is an operation or misoperation by other construction staff, the construction risk of the construction staff will be greatly increased. Therefore, planning the construction staff according to the construction site is beneficial to improving the safety of the entire construction site and ensuring that there is no risk of missed operation or misoperation when the construction operations are executed normally.

[0038] 2. In the present invention, safety detection is carried out on the single-operation construction within the construction site. By inferring whether the construction safety risk in the current construction area is normal through the safety detection of the single-operation construction, it is avoided that the single-operation construction in the current construction area causes changes in the construction environment and raises the construction risk in a local area, thereby reducing the risk management efficiency of the entire construction site. When multiple operations are being carried out in the real-time construction area, risk prediction is carried out based on the changes in the area parameters within the construction area to improve the safety performance of the construction operations in the construction area and enhance the area control of the construction area.

[0043] In order to enable the personnel in the technical field to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0044] References to "embodiments" in this specification mean that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0045] Please refer to Figure 1 As shown, a construction safety risk management system adapted to a water conservancy construction site includes a construction management platform. Among them, the construction management platform is communicatively connected to a personnel construction detection unit and a construction planning unit, and a database is connected between the personnel construction detection unit and the construction planning unit; the construction management platform is also communicatively connected to a single-operation safety detection unit and multiple-operation safety detection units; the thresholds involved in this technical solution are all parameters artificially set by those skilled in the art in the actual management process in combination with historical operation operations for numerical comparison.

[0046] The management of a water conservancy construction site is of great importance. As the construction project progresses, it is necessary to conduct safety training for all construction workers at the construction site. However, in the prior art, the safety awareness of construction workers at the actual construction site has not changed according to the actual training progress. Therefore, the construction management platform generates a personnel construction detection signal and sends the personnel construction detection signal to the personnel construction detection unit.

[0047] The personnel construction detection unit is used to detect the construction of construction workers, compare it with the actual construction scene training and the actual construction operations of construction workers, improve the efficiency of safety awareness training for construction workers, avoid the ineffectiveness of safety awareness training for construction workers, and affect the quality of construction safety risk management of the entire construction site; it should be noted that the construction safety awareness training mentioned in this technical solution is a proposition formulated for the construction scene, and the proposition processing of multiple construction workers is collected to exclude the subjective influence of each construction worker, and multiple data are used as the basis to infer the safety awareness training of the current construction site.

[0048] Based on the construction scene within the current construction period as the proposition scene, and based on the construction operations involved in the proposition scene as the proposition, record the construction operations and filling times filled in by construction workers each time, and mark the filled construction operations as theoretical operations; and detect the construction operations of construction workers during the construction period, and mark the actual construction operations as practical operations.

[0049] Analyze the construction operations of construction workers:

[0050] If the theoretical operations between adjacent tests of construction workers meet the operation standards and the theoretical operations are consistent with the practical operations, it is inferred that the construction operations of the construction workers meet the actual execution standards;

[0051] If the theoretical operations between adjacent tests of construction workers do not meet the operation standards and the theoretical operations are consistent with the practical operations, it is inferred that the construction operations of the construction workers do not meet the actual execution standards, and the construction operations of the construction workers are corrected;

[0052] If the theoretical operations between adjacent tests of construction workers meet the operation standards and the theoretical operations are inconsistent with the practical operations, it is inferred that the practical operations of the construction workers do not meet the actual execution standards, and the theoretical operation tests are ineffective. Continuous monitoring of the practical operations of this type of construction workers is carried out, and when the standards are not met, the construction operations of the corresponding construction workers are stopped;

[0053] If the theoretical operations between adjacent tests of construction workers do not meet the operation standards and the theoretical operations are consistent with the practical operations, it is inferred that the practical operations of the construction workers do not meet the actual execution standards, and the construction operations have not been corrected. The execution duration of the construction operations of the construction workers is controlled until both the theoretical operations and the practical operations meet the actual operation standards. It should be noted that the operation standards of the theoretical operations and the practical operations are the same, but there are error deviations, that is, the error of the theoretical standard is smaller than the error of the actual practical operation standard;

[0054] The theoretical operations and practical operations of the construction workers, as well as the operation changes in each corresponding cycle stage, are sent to the database for storage; according to the comparison of the operation standards of the construction workers in the database, personnel transfer is carried out to avoid the inability to execute the construction operation standards in real-time construction operation positions, increasing the risk of construction;

[0055] The construction management platform generates a construction planning signal and sends the construction planning signal to the construction planning unit;

[0056] The construction planning unit is used to carry out construction planning for the construction workers at the construction site. According to the construction planning of all construction workers, the construction continuity at the construction site is ensured, so as to ensure that there are adjacent operation intersections for the corresponding construction operations of the construction workers in each link, avoiding the information island of construction workers and the inability to ensure information exchange between construction workers when executing construction operations. At the same time, when it comes to long-distance power transmission or wading, if there are operations or misoperations by other construction workers, the construction risks of construction workers will be greatly increased. Therefore, carrying out construction worker planning according to the construction site is conducive to improving the safety of the entire construction site and ensuring that there are no risks of missed operations or misoperations when the construction operations are executed normally;

[0057] Please refer to Figure 2As shown in the figure, construction planning is carried out according to the construction operations at the construction site during each construction period. The number of construction workers for a single construction operation at the construction site is controlled to be more than one. If a single person can complete the current construction operation, the adjacent operation of the current construction operation is synchronously executed. Moreover, the construction workers of the adjacent operation and the construction workers of the current construction operation conduct a handover of work and cooperate to execute the construction operation synchronously. And when all adjacent construction operations are completed, the next construction progress can be entered; this avoids the solitary operation of construction workers at the construction site and the emergence of information islands in construction operations.

[0058] After determining the construction planning standards, the conditions required and not required for construction operations are collected, specifically whether electricity is needed or not, whether a free area is needed or not.

[0059] The process of a construction operation performed by a single person is monitored, and the conditions required and not required for the single-person construction operation and the adjacent construction operation are collected. If there are conflicts between the required conditions and the not-required conditions, the corresponding conditions are marked as conflict conditions.

[0060] When there is a deviation between the intercommunicated construction progress of the single-person construction operation and the adjacent construction operation and the actual construction progress, if the adjacent construction operation is to execute control of the conflict conditions to meet the execution requirements of the current adjacent construction operation, and the real-time progress of the single-person construction operation is not intercommunicated, then the conflict conditions are controlled to generate a risk warning signal, and the risk warning signal is sent to the construction management platform. After receiving the risk warning signal, the construction management platform re-plans the construction operations at the construction site, reduces the scenarios where adjacent or synchronous executions with conflict conditions exist, and if it cannot be avoided, continuously monitors the conflict conditions and can only control the conflict conditions after the intercommunicated construction progress. And the construction planning of the construction site and the conflict conditions of the corresponding construction operations are sent to the database for storage together; when carrying out construction planning in the next construction period, construction planning is carried out according to the database storage.

[0061] After determining the safety training and construction planning of the construction workers, the construction management platform conducts safety inspections on the real-time operations at the construction site.

[0062] The construction management platform generates a single-operation safety inspection signal and multiple-operation safety inspection signals and sends them to the single-operation safety inspection unit and the multiple-operation safety inspection unit respectively.

[0063] The single-operation safety inspection unit is used to receive the single-operation safety inspection signal and conduct safety inspections on the single-operation construction at the construction site. By inferring the construction safety risk in the current construction area through the single-operation construction safety inspection, it is avoided that the single-operation construction in the current construction area causes changes in the construction environment and leads to an increase in construction risks in a local area, thus reducing the risk management efficiency of the entire construction site.

[0064] Please refer to Figure 3 As shown, the construction operations of a single construction machine or a single construction worker are uniformly marked as a single operation, such as excavator excavation, slope operation, etc.; the construction parameters of the construction area during a single operation are collected, specifically the earthwork excavation volume in the construction area, the reduction amount of the slope height in the slope operation, etc.; among them, the construction parameters are divided into increase parameters and decrease parameters. The increase parameter means transporting materials from other areas to the current construction area, such as the transportation of relevant materials such as pipes, and the decrease parameter means transporting the materials in the current construction area to other areas, such as the excavated sand volume, etc.;

[0065] During the process of increasing construction parameters, according to the placement position of the transported materials in the construction area, the change span of the placement angle of the construction equipment during material transportation is collected. For example, if there is no placement position in the original area during material hoisting, then it is placed at the surrounding positions according to the adjusted angle. According to the increase in the swing amplitude of the material hoisting collected when the placement angle changes, and based on the increase in the change span of the placement angle and the increase in the swing amplitude, the total increase value of the span of the construction equipment when the construction parameters in the construction area increase is obtained. Among them, the total increase value of the span is calculated by summing the values of the spans, without considering the problem of inconsistent units. Moreover, the total increase value of the span is only used in the current scenario for this data, so not considering the unit problem does not affect the numerical comparison result;

[0066] During the process of decreasing construction parameters, the floating span of the levelness of the support surface in the area where the construction equipment is located is collected, and the change of support looseness is evaluated by the levelness of the support surface in the area where the construction equipment is located; this scenario is applicable to data collection and analysis when the construction equipment does not move and the hoisting angle is within the variable range. In this scenario, with the change of the hoisted materials and the real-time hoisting scenario, there is a hoisting risk for the construction equipment, and when it is within the variable range, it is often easy not to adjust the position in time;

[0067] The total increase value of the span of the construction equipment when the construction parameters in the construction area increase and the floating span of the levelness of the support surface in the area where the construction equipment is located are respectively compared with the total threshold value of the span increase and the threshold value of the floating span of the levelness:

[0068] If the total increase value of the span of the construction equipment when the construction parameters in the construction area increase exceeds the total threshold value of the span increase, or the floating span of the levelness of the support surface in the area where the construction equipment is located exceeds the threshold value of the floating span of the levelness, it is inferred that there is a position risk during the execution of a single operation in the construction area, a single operation risk signal is generated and the single operation risk signal is sent to the construction management platform. After receiving the single operation risk signal, the construction management platform replaces the position of the construction equipment and shortens the variable range of the angle of the construction equipment, and timely changes the position where the construction equipment is located when the placement position or the excavation position changes;

[0069] If the total increase in the span of the construction equipment does not exceed the span increase total threshold when the construction parameters in the construction area increase, and the floating span of the levelness of the support surface in the area where the construction equipment is located does not exceed the levelness floating span threshold, it is inferred that the construction position is safe during the single operation in the construction area, a single operation safety signal is generated and sent to the construction management platform;

[0070] Multiple operation safety detection units are used to receive multiple operation safety detection signals. After receiving them, during the execution of multiple operations in the construction area, a safety risk assessment is carried out. Through the changes in the area parameters in the construction area during the execution of multiple operations in real time, risk prediction is performed to improve the construction safety performance of the construction area operation and enhance the area control of the construction area;

[0071] During the execution of multiple construction operations in the construction area, the sand excavation volume or material placement volume in the surrounding area of each construction position is collected. Taking any construction position as the center, a force assessment is carried out based on the deformation of the surrounding area of the construction position. After excavation in the corresponding area, the force in the corresponding area decreases, and vice versa, when materials are placed in the corresponding area, the force in the corresponding area increases. According to the increase or decrease in force, the surrounding area of the current center is marked as an increased load-bearing area and a decreased load-bearing area;

[0072] When the corresponding two sides at the center position are the increased load-bearing area and the decreased load-bearing area, taking the drainage of the drainage ditch in the construction area as the area parameter, the change span value of the drainage flow rate in the construction area and the corresponding drainage ditch change path are obtained. If the increased load-bearing area is the drainage flow direction, drainage end point or passing point relative to the decreased load-bearing area; then the real-time drainage task and real-time drainage task processing capacity of the increased load-bearing area are collected, where the drainage task is expressed as the real-time drainage volume, and the processing capacity is for the drainage volume;

[0073] If the real-time drainage task and the real-time drainage task processing capacity cannot be matched at the same time, or the real-time drainage task continues to increase, it is inferred that the area parameters of the current construction area are abnormal, a regional risk warning is issued and a warning signal is sent to the construction management platform. At the same time, according to the construction progress of the construction area, a construction task replanning is carried out. That is, when constructing the increased load-bearing area and the decreased load-bearing area, it is necessary to synchronously control the floating of the area parameters to avoid phenomena such as abnormal drainage. This solution takes drainage as the area parameter. If other construction parameters are also suitable during the water conservancy construction process, specifically for area force, etc.;

[0074] If the real-time drainage task matches the real-time drainage task processing capacity at the same moment and the real-time drainage task does not continue to increase, it is inferred that the regional parameters of the current construction area are normal, and regional safety monitoring is carried out and monitoring signals are sent to the construction management platform; after receiving the monitoring signals, the construction management platform conducts real-time monitoring and control on the construction positions of the load-increasing area and the load-decreasing area, and conducts area construction on the premise of not affecting the overall coordination of the construction site or the regional parameters.

[0075] When the present invention is in use, the personnel construction detection unit conducts construction detection on construction personnel, collects data according to the construction operation detection results of the construction personnel, and sends the data to the database for storage for job scheduling; the construction planning unit conducts construction planning on the construction personnel at the construction site and sends the real-time construction planning to the database for storage; the single-operation safety detection unit conducts safety detection on the single-operation construction at the construction site, collects construction parameters, and conducts construction safety analysis and detection according to the increasing stage or the decreasing stage of the construction parameters to infer the execution risk of the single operation; the multiple-operation safety detection unit conducts safety risk assessment when multiple operations are performed in the construction area.

If the total value of the span increase of the construction equipment when the construction parameters in the construction area increase does not exceed the total span increase threshold, and the floating span of the levelness of the support surface in the area where the construction equipment is located does not exceed the levelness floating span threshold, a single operation safety signal is generated and sent to the construction management platform.

7. The construction safety risk management system adapted to the water conservancy construction site according to claim 1, wherein, The process of multiple operation safety detection units is as follows: When multiple operation construction operations are executed in the construction area, collect the sand excavation volume or material placement volume in the surrounding areas of each construction position, and take any construction position as the center. Based on the deformation of the surrounding area of the construction position, conduct a force assessment. After excavation in the corresponding area, the force in the corresponding area decreases, and vice versa, when materials are placed in the corresponding area, the force in the corresponding area increases. According to the increase or decrease of the force, mark the surrounding area of the current center as the load-increasing area and the load-decreasing area.

8. A construction safety risk management system adapted to a water conservancy construction site according to claim 7, characterized in that, When the corresponding two sides at the center position are the load-increasing area and the load-decreasing area, take the drainage of the drainage ditch in the construction area as the area parameter, obtain the change span value of the drainage flow rate in the construction area and the corresponding drainage ditch change path. If the load-increasing area is the drainage flow direction, drainage end or passing point relative to the load-decreasing area; then collect the real-time drainage task and the real-time drainage task processing capacity in the load-increasing area. If the real-time drainage task and the real-time drainage task processing capacity cannot be matched at the same time, or the real-time drainage task continues to increase, it is inferred that the area parameters of the current construction area are abnormal, a regional risk warning is issued and a warning signal is sent to the construction management platform. At the same time, according to the construction progress of the construction area, a re-planning of the construction task is carried out, that is, when the load-increasing area and the load-decreasing area are constructed, the floating control of the area parameters needs to be synchronized. If the real-time drainage task and the real-time drainage task processing capacity are matched at the same time, and the real-time drainage task does not continue to increase, it is inferred that the area parameters of the current construction area are normal, and regional safety monitoring is carried out and a monitoring signal is sent to the construction management platform.
