Description
Technical Field
[0001] The present invention belongs to the technical field of digital construction, and particularly relates to a road roller construction guidance and data recording system. Background Art
[0002] A road roller, also known as a soil compactor, is a road construction device, which is divided into two categories: steel-wheel type and tire type. Road rollers belong to the category of road equipment in construction machinery and are widely used for filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-viscous, and viscous soils, subgrade stabilized soils, and asphalt concrete pavement layers.
[0003] Currently, existing road roller equipment mainly focuses on the compaction operation itself. However, its construction guidance and data recording functions are relatively primitive. That is, during the road compaction construction process, it mainly relies on manual measurement and layout, data collection and recording. There are not only problems such as low efficiency, poor real-time performance, and lack of accuracy, but also problems such as difficult control of road surface compaction quality and insufficient data processing ability, making a large amount of data unable to be effectively managed and analyzed, and unable to provide sufficient support for construction decision-making. Therefore, how to provide a road roller construction guidance and data recording solution that can real-time guide road compaction operations, efficiently and accurately record construction data, and have a certain statistical analysis ability is an urgent research topic for those skilled in the art. Summary of the Invention

[0034] Embodiment
[0035] As Figures 1 to 3 shown, the road roller construction guidance and data recording system provided in this embodiment includes, but is not limited to, a data acquisition module, a data processing module, a data display module, a data storage module, etc.
[0036] The data acquisition module is mainly responsible for collecting the construction data of the roller, specifically including but not limited to GNSS (Global Navigation Satellite System) sensors and pavement compaction sensors, etc. Among them, the antenna of the GNSS sensor is installed on the top of the cab of the target roller, and the pavement compaction sensor is installed at the left center position or the right center position of the roller of the target roller. Specifically, the GNSS sensor is communicatively connected to the data processing module, and is used to collect the three-dimensional coordinates of the antenna in the construction coordinate system in real time, and transmit the collected results to the data processing module in real time; the construction coordinate system is also called the building coordinate system, and its coordinate axes are parallel or perpendicular to the main axes of the main buildings, so as to use the rectangular coordinate method for the lofting of buildings, which is a common term in the field of digital construction technology; since the GNSS sensor is an existing positioning device based on the global navigation satellite system and can receive signals from multiple satellite systems to provide position, time and speed information, etc., the acquisition function of its positioning data can be realized by using existing related products; specifically, the antenna includes but not limited to directional antennas and positioning antennas, etc. Among them, the directional antenna is installed on the top of the cab and on the right side when looking from the rear of the vehicle to the front of the vehicle, and the positioning antenna is installed on the top of the cab and on the left side when looking from the rear of the vehicle to the front of the vehicle, and the virtual connection line between the directional antenna and the positioning antenna is perpendicular to the vehicle central axis of the target roller. The pavement compaction sensor is communicatively connected to the data processing module, and is used to collect the pavement compaction data in real time during the rolling construction process, and transmit the collected results to the data processing module in real time; the pavement compaction sensor is a powerful, easy-to-operate and stable compaction detection device, which can provide real-time and accurate compaction monitoring for subgrade / pavement projects, and help construction personnel better control the project quality. Therefore, the acquisition function of its pavement compaction data can also be realized by using existing related products.
[0037] The data processing module is communicatively connected to the data display module and the data storage module respectively, and is used to calculate and obtain the three-dimensional coordinates of the roller in the construction coordinate system in real time according to the three-dimensional coordinates of the antenna in the construction coordinate system, then extract the horizontal two-dimensional coordinates of the roller in the construction coordinate system from the three-dimensional coordinates of the roller in the construction coordinate system and associate them with the pavement compaction data in real time, and finally transmit the association results to the data display module and the data storage module in real time respectively. The data processing module is mainly responsible for data calculation and analysis, and is preferably integrated in the software of the display and control terminal of the target roller. Specifically, calculating and obtaining the three-dimensional coordinates of the roller in the construction coordinate system in real time according to the three-dimensional coordinates of the antenna in the construction coordinate system includes but not limited to the following steps S21 to S23.
[0038] S21. Obtain multiple key points of the target roller in a fixed posture, where the multiple key points include but are not limited to the three-dimensional coordinates of the antenna of the GNSS sensor, the left endpoint and the right endpoint of the roller, etc. in the same coordinate system.
[0039] In the step S21, as Figure 3 shown, the position of the antenna of the GNSS sensor is point O, and the left endpoint of the roller is, for example but not limited to, point L, and the right endpoint of the roller is, for example but not limited to, point R. The multiple key points can be specifically obtained after being input by using surveying and mapping equipment such as total station or RTK (Real Time Kinematic). In addition, the same coordinate system can be the construction coordinate system or not.
[0040] S22. According to the multiple key points, use the inverse calculation algorithm to calculate the fixed body size of the target roller.
[0041] In the step S22, as Figure 3 shown, specifically, the fixed body size includes but is not limited to the length of the first virtual line segment OA, the length of the second virtual line segment AG, the length of the third virtual line segment LG, the length of the fourth virtual line segment RG, etc. Among them, the first virtual line segment PA refers to the virtual line segment from point O to point A, the second virtual line segment AG refers to the virtual line segment from point A to point G, the third virtual line segment LG refers to the virtual line segment from point L to point G, the fourth virtual line segment RG refers to the virtual line segment from point R to point G. Point O refers to the position of the antenna of the GNSS sensor, point L refers to the left endpoint of the roller, point R refers to the right endpoint of the roller, point A refers to the projection point of point O projected vertically downward on the horizontal plane where point L and point R are located, and point G refers to the projection point of point A projected forward along the vehicle body direction in the horizontal plane where point A is located on the vertical plane where point L and point R are located. In addition, the inverse calculation algorithm refers to an algorithm for calculating and calibrating intermediate dimensions based on multiple known side points, and its specific calculation process can be routinely derived based on existing geometric knowledge, which will not be elaborated here.
[0042] S23. According to the fixed body size of the target roller and the three-dimensional coordinates of the antenna in the construction coordinate system, use the forward calculation algorithm to calculate in real time the three-dimensional coordinates of the roller in the construction coordinate system, where the three-dimensional coordinates of the roller in the construction coordinate system include but are not limited to the three-dimensional coordinates of the left endpoint and the right endpoint of the roller in the construction coordinate system.
[0043] In the step S23, the forward calculation algorithm refers to an algorithm for calculating the position of one side based on the intermediate size and the known position of one side. The specific calculation process can also be routinely derived based on existing geometric knowledge, which will not be elaborated here. In addition, when the three-dimensional coordinates of the pressing wheel in the construction coordinate system include, but are not limited to, the three-dimensional coordinates of the left and right endpoints of the pressing wheel in the construction coordinate system, the three-dimensional coordinates and the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system can both be represented by a line segment between the left endpoint and the right endpoint.
[0044] The data display module is used to display in real time the relative position relationship between the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and the design coordinates in the road rolling construction design plan, so as to complete real-time construction position guidance, and also display in real time the road surface compaction degree data associated with the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system. Among them, the design coordinates refer to the horizontal two-dimensional coordinates of the road surface to be compacted in the construction coordinate system. The data display module is mainly responsible for the output display of relevant content and is preferably integrated in the software of the display and control terminal. The aforementioned design coordinates in the road rolling construction design plan can be routinely obtained by adding the construction range coordinates, so that after displaying in real time the relative position relationship between the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and the design coordinates in the road rolling construction design plan, the operator can be guided to carry out construction operations, so that the target roller always constructs within the correct design range. In addition, the road rolling construction design plan may also include, but is not limited to, relevant process parameters of road rolling construction, etc.
[0045] The data storage module is used to record the construction start time, construction end time, real-time construction position during the road rolling construction process, and the road surface compaction degree data associated with this construction position, etc. Among them, the construction position refers to the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system. The data storage module is mainly responsible for data storage and can be integrated in the storage unit of the display and control terminal.
[0046] Based on the above-mentioned road roller construction guidance and data recording system, a new auxiliary solution for road roller equipment with construction guidance and data recording functions is provided, which includes a data acquisition module, a data processing module, a data display module, and a data storage module. Among them, the data acquisition module includes a GNSS sensor and a road surface compaction sensor. The antenna of the GNSS sensor is installed on the top of the cab of the target road roller, and the road surface compaction sensor is installed at the left or right central position of the roller of the target road roller. Through the cooperation of the foregoing functional modules, construction can be guided in real time based on the design data to ensure that the target road roller always operates within the correct design range, and can automatically collect, process, and store road roller construction data, improve the accuracy and real-time nature of construction records, reduce construction costs, simplify the management of the construction process, improve construction efficiency, perform data statistics and analysis, facilitate the monitoring of construction quality, and facilitate data decision-making and construction guidance, which is convenient for practical application and promotion.
[0047] Preferably, it further includes a data transmission module communicatively connected to the data storage module. Among them, the data transmission module is used to upload the construction data in the data storage module to a designated server by means of medium transmission (that is, the method of copying construction data) and / or network transmission. Among them, the construction data includes but is not limited to the construction start time, construction end time of the target road roller, the real-time construction position during the road rolling construction process, and the road surface compaction data associated with the construction position, etc. After the construction data is uploaded to the designated server, it can be used for summary analysis of construction data on the server side, so as to further achieve the purpose of transmitting road roller construction data and improve the practicability of the system.
[0048] Preferably, the data processing module is further used to determine the driving speed of the roller in the construction coordinate system in real time according to the two horizontal two-dimensional coordinates of the roller in the construction coordinate system that are adjacent before and after, and transmit the driving speed to the data display module in real time for real-time display. The specific determination method of the foregoing driving speed is a conventional existing method. For example, dividing the distance between the two horizontal two-dimensional coordinates by the acquisition time difference between the two horizontal two-dimensional coordinates can obtain the specific value of the driving speed. Through the foregoing technical means, the data processing and analysis capabilities can be improved, making the entire system further practical. In addition, the data storage module is further used to record the driving speed of the roller in the construction coordinate system determined in real time according to the two horizontal two-dimensional coordinates of the roller in the construction coordinate system that are adjacent before and after, and the construction data can also include the driving speed.
[0049] Preferably, the data processing module is further configured to, according to all the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and since the start time of the construction of the target roller and all the design coordinates in the road rolling construction design plan, determine in real time the number of times the pressing wheel passes through the same design coordinate among all the design coordinates, and use the number of times as the rolling passes corresponding to the same design coordinate. Then, according to all the latest rolling passes corresponding one by one to all the design coordinates, draw in real time the rolling passes distribution map of the road surface to be compacted, and transmit the rolling passes distribution map to the data display module in real time for real-time display. Since the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and the design coordinates can be regarded as being on the same horizontal plane, the number of times the pressing wheel passes through the design coordinate can be determined based on the coincidence of the two coordinates: if they coincide once in time sequence, it means the pressing wheel passes through the design coordinate once, and the corresponding rolling passes are incremented by 1 (at the start time of the construction, the rolling passes corresponding to all the design coordinates will be initialized to zero), and so on. Thus, through the foregoing technical means, the data processing and analysis capabilities can also be improved, making the entire system further practical. In addition, the data storage module is further configured to record the latest rolling passes determined in real time according to all the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and since the start time of the construction of the target roller and all the design coordinates in the road rolling construction design plan and corresponding to each design coordinate among all the design coordinates, and the construction data may also include the latest rolling passes.
[0050] Preferably, the data processing module is further configured to, according to all the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and since the start time of the construction of the target roller and all the design coordinates in the road rolling construction design plan, determine in real time the current completion progress of the road rolling construction design plan, and transmit the current completion progress to the data display module in real time for real-time display. Since the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and the design coordinates can be regarded as being on the same horizontal plane, the ratio of the area determined based on all the horizontal two-dimensional coordinates to the area determined based on all the design coordinates can be directly used as the current completion progress of the road rolling construction design plan. Thus, through the foregoing technical means, the data processing and analysis capabilities can also be improved, making the entire system further practical.
[0051] Preferably, the data processing module is further configured to, according to all the horizontal two-dimensional coordinates of the pressing wheel in the construction coordinate system and since the start time of the construction of the target roller, and all the latest road surface compaction data associated with the all horizontal two-dimensional coordinates one by one, draw a compaction distribution map of the road surface to be compacted in real time, and transmit the compaction distribution map to the data display module in real time for real-time display. Thus, through the foregoing technical means, the data processing and analysis capabilities can also be improved, making the entire system further practical.
