[0002] During the maintenance and construction of bridges, it is often necessary to build a hanger device to build a construction platform. Therefore, in order to ensure the safety of the hanger device, in the invention patent application CN202410814817.6 "BIM-based hanger load calculation method, device, equipment and medium", the hanger model obtained by the BIM model is processed multiple times to obtain the load parameters, and the load calculation results of the hanger model are quickly calculated based on the load parameters and the preset load strategy to ensure the load safety of the hanger device. However, it is not difficult to find the following technical problems through analysis:

[0008] S1: determining the parts to be maintained of the bridge, determining the setting scheme of the construction hanger device based on the distribution of the parts to be maintained, determining the maintenance treatment time of different parts to be maintained by using the setting scheme, and determining the available setting schemes in the setting scheme in combination with the fault hidden danger data of different parts to be maintained;

[0009] S2: obtaining the setting position and setting method of the construction hanger device of the available setting scheme, and determining the safety factors of different available setting schemes in combination with the construction personnel and construction duration of different construction hanger devices, and determining the safe setting scheme among the available setting schemes by using the safety factors;

[0012] A further technical solution is that the parts of the bridge to be maintained are determined based on the inspection results of different parts of the bridge, and specifically the parts with abnormal inspection results are used as the parts of the bridge to be maintained.

[0013] A further technical solution is that the setting scheme of the construction hanger device includes different setting positions, setting methods and setting times of the construction hanger device.

[0014] A further technical solution is that the method for determining the safety factor of the available setting scheme is:

[0028] The beneficial effects of the present invention are:

[0029] 1. In the present invention, the traffic impact coefficients in different safety setting schemes are determined by utilizing road occupancy data and historical traffic flow, and full consideration is given to the impact of different safety setting schemes on road traffic caused by differences in road occupancy time and historical traffic flow in different safety setting schemes. This also lays the foundation for selecting safety setting schemes with lower impact on road traffic, and minimizes the impact of bridge maintenance and management on bridge road traffic.

[0030] 2. In the present invention, the optimal solution in the safety setting plan is determined by the construction time, traffic impact coefficient and safety factor of the safety setting plan, thereby avoiding the technical problem that the setting plan of the hanger device cannot meet the needs of road maintenance due to the single consideration of a certain dimension of factors, and realizing the determination of the optimal maintenance plan from multiple dimensions. On the basis of ensuring that the construction time is controllable, comprehensive consideration of traffic impact and safety is achieved.

Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0040] To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, a maintenance management method based on bridge maintenance is provided, which specifically includes:

[0041] S1: determining the parts to be maintained of the bridge, determining the setting scheme of the construction hanger device based on the distribution of the parts to be maintained, determining the maintenance treatment time of different parts to be maintained by using the setting scheme, and determining the available setting schemes in the setting scheme in combination with the fault hidden danger data of different parts to be maintained;

[0042] Furthermore, the parts of the bridge to be maintained are determined based on the inspection results of different parts of the bridge, and specifically the parts with abnormal inspection results are taken as the parts of the bridge to be maintained.

[0043] It should be noted that the setting scheme of the construction hanger device includes different setting positions, setting methods and setting times of the construction hanger device.

[0044] It is understandable that if Figure 2 As shown, the method for determining the available setting schemes in the setting scheme is:

[0045] Determine the types of potential faults of different parts to be maintained based on the potential fault data of different parts to be maintained, and determine the severity of the faults of different parts to be maintained based on the fault characteristics of the potential faults of different parts to be maintained;

[0046] Determine the reliability coefficient of maintenance treatment for different parts to be maintained according to the severity of the faults of different parts to be maintained and the time required for maintenance treatment;

[0047] The availability coefficient of the setting scheme is determined by the average value of the maintenance treatment reliability coefficients of different parts to be maintained, and the available setting schemes in the setting scheme are determined by using the availability coefficient.

[0048] Further, when the available coefficient of the setting scheme is greater than a preset coefficient threshold, the setting scheme is determined to be an available setting scheme.

[0049] It should also be noted that the maintenance treatment reliability coefficient of the maintenance part is determined according to the ratio of the treatment time threshold corresponding to the fault severity of the maintenance part to the maintenance treatment time.

[0050] It can be understood that the method for determining the available setting schemes in the setting scheme is:

[0051] Determine the types of potential faults of different parts to be maintained based on the potential fault data of different parts to be maintained, and determine the severity of the faults of different parts to be maintained based on the fault characteristics of the potential faults of different parts to be maintained;

[0052] Based on the severity of the faults of different parts to be maintained, the preset maintenance treatment risks of different parts to be maintained in different treatment time intervals are determined, and the maintenance treatment risks of different parts to be maintained are determined according to the preset maintenance treatment risks and maintenance treatment times in different treatment time intervals;

[0053] The risky parts of the parts to be maintained are determined according to the maintenance treatment risks of different parts to be maintained, and the available setting schemes in the setting schemes are determined by using the number of the risky parts.

[0054] Further, when the number of risk locations is within a preset interval, the setting scheme is determined to be an available setting scheme.

[0055] It can be understood that the method for determining the available setting schemes in the setting scheme is:

[0056] S11: obtaining the maintenance treatment time of different parts to be maintained in the setting scheme, and judging whether the average maintenance treatment time of different parts to be maintained is greater than the preset treatment time. If so, determining that the setting scheme does not belong to the available setting scheme, if not, proceeding to the next step;

[0057] S12 determines whether there is a part to be maintained in the setting scheme whose maintenance time is greater than the preset treatment time. If yes, proceed to step S15; if not, proceed to the next step;

[0058] S13 determines the types of the fault hazards of the different parts to be maintained based on the fault hazard data of the different parts to be maintained, and determines the fault severity of the different parts to be maintained according to the fault characteristics of the different parts to be maintained, and determines whether there is a part to be maintained whose fault severity is not within the preset severity range. If so, proceed to the next step; if not, determine that the setting scheme belongs to the available setting scheme;

[0059] S14 obtains the maintenance part whose fault severity is not within the preset severity range, and regards it as a serious risk part, and determines whether there is a serious risk part whose maintenance time does not meet the requirements. If not, proceed to the next step. If so, determine that the setting scheme does not belong to the available setting scheme.

[0060] S15 determines preset maintenance treatment risks of different parts to be maintained in different treatment time intervals based on the fault severity of different parts to be maintained, determines the maintenance treatment risks of different parts to be maintained according to the preset maintenance treatment risks and maintenance treatment times in different treatment time intervals, and judges whether there is a part to be maintained whose maintenance treatment risk does not meet the requirements. If not, proceed to the next step. If yes, determine that the setting scheme does not belong to the available setting scheme.

[0061] S16 determines the risky parts of the parts to be maintained according to the maintenance treatment risks of different parts to be maintained, and determines the available setting schemes in the setting schemes according to the number of the risky parts.

[0062] S2: obtaining the setting position and setting method of the construction hanger device of the available setting scheme, and determining the safety factors of different available setting schemes in combination with the construction personnel and construction duration of different construction hanger devices, and determining the safe setting scheme among the available setting schemes by using the safety factors;

[0063] Specifically, Figure 3 As shown, the method for determining the safety factor of the available setting scheme is:

[0064] Determine the construction safety factor of the construction hanger device under different numbers of construction personnel according to the setting position and setting method of the construction hanger device;

[0065] Determine the construction duration of the construction hanger device under different numbers of construction workers according to the number of construction workers at different construction periods, and determine the device safety factor of different construction hanger devices in combination with the construction safety factor of the construction hanger device under different numbers of construction workers;

[0066] The safety factors of the available setting solutions are determined based on the weights of the device safety factors of different construction hanger devices.

[0067] Furthermore, the safety factor of the available setting scheme ranges from 0 to 1, wherein when the safety factor of the available setting scheme is greater than a preset safety factor threshold, the available setting scheme is determined to be a safe setting scheme.

[0068] It should also be noted that the method for determining the safety factor of the available setting scheme is:

[0069] Determine the construction safety factor of the construction hanger device under different numbers of construction workers according to the setting position and setting mode of the construction hanger device, and use the construction safety factor to determine the number of risky construction workers;

[0070] Determine the construction time of the construction hanger device under the number of risky construction workers according to the number of construction workers of different construction hanger devices in different construction periods, and determine the proportion of risky construction time by using the construction time under the number of risky construction workers;

[0071] The proportion of the risky construction duration to the construction hanger device that does not meet the requirements is used as the safety factor of the available setting scheme.

[0072] It should be further explained that the method for determining the safety factor of the available setting scheme is:

[0073] S21: determining the construction safety factor of the construction hanger device under different numbers of construction workers according to the setting position and setting mode of the construction hanger device, and determining the number of risky construction workers by using the construction safety factor;

[0074] S22 determines whether the construction hanger device has a corresponding construction period under the number of risky construction workers according to the number of construction workers of different construction hanger devices in different construction periods. If yes, proceed to the next step; if not, proceed to the step;

[0075] S23 determines the construction duration of the construction hanger device under different numbers of risky construction personnel based on the corresponding construction period, and determines the proportion of risky construction duration based on the construction duration under the number of risky construction personnel, and judges whether the number of construction hanger devices whose risky construction duration proportion in the available setting scheme does not meet the requirement meets the requirement, if so, proceeds to the next step, if not, determines that the available setting scheme does not belong to the safe setting scheme;

[0076] S24 obtains the construction duration under different numbers of risky construction personnel, and determines the screening risk coefficient of the construction hanger device in combination with the construction safety factor under different numbers of risky construction personnel, and determines whether the number of construction hanger devices whose screening risk coefficient does not meet the requirement meets the requirement, if so, proceeds to the next step, if not, determines that the available setting scheme does not belong to the safe setting scheme;

[0077] S25: determining the device safety factors of different construction hanger devices according to the construction duration of the construction hanger device under different numbers of construction personnel and the construction safety factors under different numbers of construction personnel, and judging whether the number of construction hanger devices whose device safety factors do not meet the requirements meets the requirements, if so, proceeding to the next step, if not, determining that the available setting scheme does not belong to the safe setting scheme;

[0078] S26 determines the safety factor of the available setting scheme based on the weights of the device safety factors of different construction hanger devices.

[0079] S3 determines the road occupancy data of the safety setting scheme based on the setting position and setting mode of the construction hanger device of the safety setting scheme, and determines the traffic impact coefficients in different safety setting schemes using the road occupancy data and historical traffic flow;

[0080] Furthermore, the road occupancy data includes occupancy time and occupancy length of different lanes.

[0081] It is understandable that the historical traffic flow is determined based on monitoring data of traffic flows of different lanes on different historical dates.

[0082] Specifically, Figure 4 As shown, the method for determining the traffic impact coefficient is:

[0083] Determine the occupied lane of the bridge using the road occupation data, and determine the average traffic flow of the occupied lane using monitoring data of the traffic flow of the occupied lane on different historical dates;

[0084] Different lane influence coefficients of occupied lanes are calculated based on different occupied lane occupation times, occupied lengths and average traffic flows;

[0085] The traffic impact coefficient in the safety setting scheme is determined according to the lane impact coefficients of different occupied lanes.

[0086] It can be understood that the method for determining the lane influence coefficient is:

[0087] Determining a lane occupancy rate of the occupied lane based on a proportion of the occupied length to the length of the occupied lane;

[0088] Determining the influence amount of the traffic flow of the occupied lane based on the product of the lane occupancy rate and the average traffic flow;

[0089] The influence amount of the traffic flow of the occupied lane and the occupation time are taken as input quantities, and a preset mapping function is used to determine the lane influence coefficient of the occupied lane.

[0090] Furthermore, the traffic impact coefficient in the safety setting scheme has a value range between 0 and 1, wherein the larger the traffic impact coefficient in the safety setting scheme is, the higher the degree of impact of the safety setting scheme on the traffic of the bridge is.

[0091] In another embodiment, the method for determining the traffic impact coefficient is:

[0092] S31 determines the occupied lanes of the bridge based on the road occupation data, and judges whether the number of occupied lanes in the safety setting scheme is greater than the preset number of lanes. If not, proceed to the next step. If yes, determine that the safety setting scheme is not an optimal setting scheme.

[0093] S32 determines whether the number of occupied lanes in the safety setting scheme is within a preset lane number range, if so, proceeds to the next step, if not, proceeds to step;

[0094] S33 determines the average traffic flow of the occupied lane by using the monitoring data of the traffic flow of the occupied lane on different historical dates, and judges whether the sum of the average traffic flows of different occupied lanes in the safety setting scheme meets the requirements, if so, proceeds to the next step, if not, determines that the safety setting scheme does not belong to the optimal setting scheme;

[0095] S34 determines the number of historical dates whose traffic flow ratios are greater than a preset traffic flow ratio based on the traffic flow ratios of all occupied lanes on different historical dates, and determines whether the number of historical dates whose traffic flow ratios are greater than the preset traffic flow ratios meets the requirement. If so, proceed to the next step. If not, determine that the safety setting scheme does not belong to the optimal setting scheme.

[0096] S35: performing lane influence coefficients of different occupied lanes based on different occupied time, occupied length and average traffic flow of the occupied lanes, and judging whether the number of occupied lanes whose lane influence coefficients are greater than a preset coefficient threshold meets the requirement, and if so, proceeding to the next step; if not, determining that the safety setting scheme is not an optimal setting scheme;

[0097] S36 determines the traffic impact coefficient in the safety setting scheme according to the lane impact coefficients of different occupied lanes.

[0098] S4 determines the optimal solution among the safety setting solutions according to the construction time, traffic impact coefficient and safety factor of the safety setting solutions.

[0099] Specifically, the method for determining the optimal solution in the security setting solution is:

[0100] The optimal solution in the safety setting scheme is determined by the construction time, traffic impact coefficient and safety factor of the safety setting scheme.

[0101] Determine the comprehensive priority value of the safety setting plan based on the construction time, traffic impact coefficient and safety factor of the safety setting plan;

[0102] The comprehensive priority value is used to determine the optimal solution among the security setting solutions.

[0103] Furthermore, the comprehensive priority value in the safety setting scheme is determined by the output result of a preset linear mapping function with the construction duration, traffic impact coefficient and safety factor of the safety setting scheme as input quantities.

[0104] Second, as Figure 5 As shown, the present invention provides a hanger device, which is applied to the above-mentioned maintenance management method based on bridge maintenance, specifically comprising:

[0105] Safety assessment module, signal transmission module;

[0106] The safety assessment module is responsible for determining the sway data of the hanger device using the monitoring device of the hanger device, and assessing the safety status using the sway amplitude;

[0107] The signal transmission module is responsible for uploading the monitoring data of the monitoring device of the hanger device to the cloud.
