Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method, device, equipment and storage medium for monitoring illegal behaviors in bridge construction. Background Art

[0002] As an important means of transportation connecting two places, bridges have an important strategic position. Bridge construction is difficult and the construction process is very complicated, involving many links. At the same time, monitoring of bridge construction violations has become an indispensable safety project in the process of bridge construction because of its significant role and significance in ensuring the quality of bridge projects, ensuring construction safety, controlling construction progress, and improving construction efficiency.

[0003] The traditional manual monitoring of bridge construction violations has the problems of low monitoring efficiency, strong subjectivity, difficulty in monitoring multiple steps in multiple links, and low monitoring accuracy. With the maturity and application of drone technology, the introduction of violation monitoring drones in bridge construction violation monitoring has become a hot trend. The application of drones can provide more efficient and accurate violation monitoring for bridge construction, avoiding the influence of human subjective judgment. However, the existing violation monitoring drones still have some limitations in bridge construction monitoring in some scenarios: (1) There are differences in the monitoring distances for violations: Considering that the bridge construction process is complex, it usually includes multiple construction steps in multiple links. In view of the different construction scenarios and requirements of different bridges, different violation monitoring distance standards are applied to many links and steps (for example, in the upper structure construction link, the image acquisition of the joints between precast beams and cast-in-place beams to check the setting of connecting steel bars and the pouring quality of concrete requires close-range image acquisition within 20 meters; in the lower structure construction link, the image acquisition of the construction of piers and abutments to check whether the spacing, number, and binding firmness of steel bars meet the design requirements requires medium-range image acquisition of 20 to 50 meters; and the image acquisition for the location and status monitoring of large equipment requires long-range image acquisition of more than 50 meters). Different violation monitoring distance standards increase the difficulty of drones in executing flight planning and image acquisition in the construction area. (2) There are differences in the frequency of monitoring violations: Considering that in the scenario of progressive bridge construction, since each bridge construction section may perform different construction processes at the same time, violation monitoring drones need to simultaneously respond to the monitoring needs of different construction processes and different construction scenarios. Different construction processes in different construction scenarios usually have different violation monitoring frequency standards (for example, the concrete pouring process of large-volume bridge piers requires image acquisition every hour or even shorter time intervals to ensure timely detection of violations such as segregation and loose vibration during the layered pouring of concrete; the image acquisition every 3-6 hours is required to monitor the sealing degree and use status of drainage pipes during construction; the image acquisition every 3-5 days is required to monitor cracks, peeling, rust, etc. on the surface of bridge piers and beams). Different violation monitoring frequency standards further increase the difficulty of flight planning and image acquisition of drones in the construction area. (3) There are limitations on the endurance of violation monitoring drones in actual applications. In order to improve the monitoring capability of violation monitoring drones, it is necessary to optimize the flight path of violation monitoring drones when performing flight planning and image acquisition.

[0004] Therefore, how to provide flight planning and image acquisition control solutions for violation monitoring UAVs that are adapted to different violation monitoring distances and violation monitoring frequencies for several construction steps in the numerous links of bridge construction, while improving the accuracy and efficiency of bridge construction violation monitoring, and extending the monitoring time of violation monitoring UAVs during flight planning and image acquisition as much as possible, is a technical problem that needs to be solved urgently.

[0025] The specific embodiments of the present invention applied to the device are basically the same as the embodiments of the following bridge construction violation monitoring method, and will not be described in detail here.

[0026] The embodiment of the present invention provides a method for monitoring illegal behavior in bridge construction, referring to Figure 2 , Figure 2 It is a flow chart of an embodiment of a method for monitoring bridge construction violations according to the present invention.

[0027] In this embodiment, the bridge construction violation monitoring method includes the following steps: S100: Obtaining bridge construction plan information; wherein the bridge construction plan information includes a number of bridge construction sections in the target construction bridge, a number of construction processes of each bridge construction section, and a planned time period for each bridge construction section to perform each construction process; S200: determining a number of construction monitoring points of the target construction bridge and an effective monitoring period of each construction monitoring point according to a number of construction procedures of each bridge construction section and a planned period for each bridge construction section to execute each construction procedure; S300: obtaining a pre-determined bridge construction monitoring requirement, extracting the monitoring type information and monitoring risk level of each construction monitoring point in the bridge construction monitoring requirement, considering the effective monitoring period of each construction monitoring point, taking the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level as constraints, taking the minimum flight distance as the optimization target, and optimizing and solving the UAV image acquisition path planning strategy for the target construction bridge; S400: Based on the UAV image acquisition path planning strategy, generate UAV flight and image acquisition control instructions, drive the violation monitoring UAV to perform corresponding flight and image acquisition actions, and perform bridge construction violation judgment based on the collected bridge construction images; S500: After the violation monitoring UAV completes each flight and image acquisition action, the bridge construction progress is obtained, the bridge construction plan information is updated based on the bridge construction progress, and the UAV image acquisition path planning strategy is regenerated using the updated bridge construction plan information.

[0028] It should be noted that the existing violation monitoring drones still have some limitations in bridge construction monitoring in some scenarios: (1) There are differences in violation monitoring distances: Considering that the bridge construction process is complex, it usually includes multiple construction steps in multiple links. Different construction scenarios and requirements of different bridges make different violation monitoring distance standards for many links and many construction steps. Different violation monitoring distance standards increase the difficulty of drones in executing flight planning and image acquisition in the construction area. (2) There are differences in violation monitoring frequency: Considering that in the scenario of progressive bridge construction, each bridge construction section may perform different construction processes at the same time, and the violation monitoring drone needs to simultaneously respond to the monitoring needs of different construction processes and construction scenarios. Different construction processes in different construction scenarios usually have different violation monitoring frequency standards. Different violation monitoring frequency standards further increase the difficulty of drones in executing flight planning and image acquisition in the construction area. (3) There are endurance limitations in the actual application of violation monitoring drones. In order to improve the monitoring capability of violation monitoring drones, it is necessary to optimize the flight path of violation monitoring drones when executing flight planning and image acquisition.

[0029] In order to solve the above problems, this embodiment obtains the bridge construction plan information, uses the planned time period of each bridge construction section in executing each construction process, determines the effective monitoring period of each construction monitoring point, and considers the monitoring type information and monitoring risk level of each construction monitoring point in the pre-formulated bridge construction monitoring requirements, takes the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level as constraints, takes the flight distance as the optimization target, optimizes and solves the drone image acquisition path planning strategy for the target construction bridge, and then controls the drone to perform flight and image acquisition and bridge construction violation judgment. Therefore, the present invention proposes a construction image acquisition scheme that adapts to the different monitoring distances and different monitoring frequencies of different construction links in the bridge construction process, while improving the accuracy and efficiency of bridge construction violation monitoring, and prolongs the monitoring time of the violation monitoring drone as much as possible, and has good scene adaptability.

[0030] In a preferred embodiment, the step of obtaining bridge construction plan information specifically includes: S110: Acquire historical bridge construction progress information of the bridge construction subject, extract the historical time consumption of each construction process in different reference bridge construction sections in the historical bridge construction progress information, acquire the target bridge construction task, and extract several bridge construction sections and several construction processes of each bridge construction section in the target construction bridge recorded in the target bridge construction task; S120: performing similarity matching between the construction content features of the reference bridge construction section and each bridge construction section in the target construction bridge, and matching each bridge construction section with a number of reference bridge construction sections whose construction content feature similarity is higher than a target value; S130: based on the historical time consumption of each construction process in a plurality of reference bridge construction sections having a matching relationship in each bridge construction section, the planned time consumption of each construction process in each bridge construction section is calculated by accumulating the average value of the historical time consumption; S140: Determine the planned time period for executing each construction process in each bridge construction section according to the planned time consumption of each construction process in each bridge construction section, and generate bridge construction plan information using the planned time period for each construction process.

[0031] In this embodiment, by obtaining the historical bridge construction progress information of the bridge construction entity, according to the historical time consumption of each construction process in different reference bridge construction sections of the bridge construction entity, firstly, a construction content feature similarity matching method is used to match each bridge construction section with several corresponding reference bridge construction sections, and then the historical time consumption of each construction process in several reference bridge construction sections is averaged, which is used as the planned time consumption of each construction process in each bridge construction section. Finally, according to the planned time consumption of each construction process and the execution order of the bridge construction sections and the construction processes, the planned time period of each construction process is determined to generate the final bridge construction plan information.

[0032] In a preferred embodiment, according to a number of construction processes of each bridge construction section and a planned period for each bridge construction section to execute each construction process, a number of construction monitoring points of the target construction bridge and an effective monitoring period of each construction monitoring point are determined, specifically including: S210: using a number of construction processes of each bridge construction section, matching the construction monitoring project of each construction process in a pre-defined list of bridge construction monitoring projects, querying the construction monitoring position of each construction monitoring project by calling the target construction bridge drawing, and obtaining a number of construction monitoring points; S220: Determine the effective monitoring period of each construction monitoring point corresponding to each construction process according to the planned period of execution of each construction process in each bridge construction section.

[0033] In this embodiment, by calling a pre-established list of bridge construction monitoring items, the construction monitoring points of each construction process in each bridge construction section are determined through the construction monitoring items of each construction process recorded in the list of bridge construction monitoring items, and then the effective monitoring time period of each construction monitoring point corresponding to each construction process is determined in combination with the planned time period of each construction process.

[0034] In a preferred embodiment, a pre-established bridge construction monitoring requirement is obtained, the monitoring type information and monitoring risk level of each construction monitoring point in the bridge construction monitoring requirement are extracted, the effective monitoring period of each construction monitoring point is considered, the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level are used as constraints, and the minimum flight distance is used as the optimization target. The steps of optimizing and solving the UAV image acquisition path planning strategy for the target construction bridge specifically include: S310: obtaining a pre-determined bridge construction monitoring requirement, and extracting monitoring type information and monitoring risk level of each construction monitoring point in the bridge construction monitoring requirement; wherein the monitoring type includes monitoring types of construction violations corresponding to a number of different image acquisition distance intervals, and the monitoring risk level includes monitoring risk levels of construction violations corresponding to a number of different image acquisition frequency intervals; S320: using the monitoring type information and the monitoring risk level, respectively matching the image acquisition distance and the image acquisition frequency of each construction monitoring point in a first mapping comparison table of preset monitoring types and image acquisition distance intervals and a second mapping comparison table of preset monitoring risk levels and image acquisition frequency intervals; S330: Considering the effective monitoring period of each of the construction monitoring points, taking the image acquisition distance interval and the image acquisition frequency interval as constraints, taking the minimum flight distance as the optimization goal, optimizing and solving the UAV image acquisition path planning strategy for the target construction bridge.

[0035] Furthermore, considering the effective monitoring period of each construction monitoring point, taking the image acquisition distance interval and the image acquisition frequency interval as constraints, taking the minimum flight distance as the optimization goal, the steps of optimizing and solving the UAV image acquisition path planning strategy for the target construction bridge include: S331: constructing a three-dimensional model map of the target construction bridge, and generating an effective monitoring area for each construction monitoring point in the three-dimensional model map according to the image acquisition distance interval of each construction monitoring point; S332: Obtain the flight speed range of the violation monitoring drone, consider the effective monitoring period and effective monitoring area of ​​each of the construction monitoring points, select a number of drone collection points within the effective monitoring period and the effective monitoring area, and use the image collection interval time corresponding to two adjacent drone collection points in each drone image collection path in the generated drone image collection path as the first constraint condition and the image collection interval time corresponding to two adjacent drone collection points of each construction monitoring point in the generated drone image collection path as the second constraint condition, and use the minimum cumulative sum of flight distances of the violation monitoring drone in the generated drone image collection paths as the optimization goal, and optimize the image collection time and image collection position of each drone collection point in the generated drone image collection paths; S333: Generate a UAV image acquisition path planning strategy for the target construction bridge according to the image acquisition time and image acquisition position of each UAV acquisition point in several UAV image acquisition paths.

[0036] In this embodiment, after determining the effective monitoring period of each construction monitoring point, the monitoring type information and the monitoring risk level of each construction monitoring point in the pre-established bridge construction monitoring requirements are taken into consideration, and the image acquisition distance interval corresponding to the monitoring type information and the image acquisition frequency interval corresponding to the monitoring risk level are used as constraints. The flight distance is taken as the optimization target, and the UAV image acquisition path planning strategy for the target construction bridge is optimized. Finally, a number of UAV acquisition points used for UAV flight and image acquisition when performing bridge construction violation monitoring on the target construction bridge, as well as the image acquisition time and image acquisition position of each UAV acquisition point are obtained, so as to obtain a construction image acquisition scheme that adapts to different monitoring distances and different monitoring frequencies in different construction links during the bridge construction process.

[0037] In a preferred embodiment, based on the UAV image acquisition path planning strategy, UAV flight and image acquisition control instructions are generated to drive the violation monitoring UAV to perform corresponding flight and image acquisition actions, and perform bridge construction violation judgment steps according to the collected bridge construction images, specifically including: S410: extracting the image acquisition time and image acquisition position of each drone acquisition point in each drone image acquisition path in the drone image acquisition path planning strategy, and calculating the flight speed between two adjacent drone acquisition points in each drone image acquisition path; S420: generating a UAV flight control instruction based on the image acquisition position of each UAV acquisition point and the flight speed between two adjacent UAV acquisition points, generating a UAV image acquisition instruction based on the image acquisition time of each UAV acquisition point, and obtaining a UAV flight and image acquisition control instruction; S430: Sending the UAV flight and image acquisition control instructions to the violation monitoring UAV, driving the violation monitoring UAV to execute corresponding flight and image acquisition actions, and performing bridge construction violation judgment based on the collected bridge construction images.

[0038] On this basis, after the violation monitoring drone completes each flight and image acquisition action, the bridge construction progress is obtained, the bridge construction plan information is updated based on the bridge construction progress, and the drone image acquisition path planning strategy steps are regenerated using the updated bridge construction plan information, specifically including: S510: After the violation monitoring drone completes each flight and image acquisition action, the bridge construction progress of the target construction bridge is obtained, and the actual time period during which the construction process is currently being executed in each bridge construction section in the bridge construction progress is extracted; S520: Based on the planned time period for executing each construction process in each bridge construction section in the bridge construction plan information and the actual time period for currently executing the construction process in each bridge construction section in the bridge construction progress, it is determined whether the time overlap ratio between the actual time period and the planned time period for executing the corresponding construction process is lower than a preset target ratio; if so, the construction process corresponding to the actual time period is defined as an error process; S530: Determine whether the number of error processes in the construction processes currently being executed in each bridge construction section in the bridge construction progress exceeds the preset target number. If so, update the bridge construction plan information based on the bridge construction progress, and use the updated bridge construction plan information to regenerate the drone image acquisition path planning strategy.

[0039] In this embodiment, after obtaining the UAV image acquisition path planning strategy for the target construction bridge, the flight speed between two adjacent unmanned acquisition points in each UAV image acquisition path is calculated according to the image acquisition time and image acquisition position of each UAV acquisition point, so as to guide the UAV to perform the corresponding flight and image acquisition actions.
