Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevation measurement technology, specifically to an elevation information acquisition system for 3D paving. Background Technology
[0002] In the construction of bridge and tunnel pavement, the elevation acquisition of the asphalt paving layer is a crucial quality control step to ensure that the pavement smoothness and structural layer thickness meet design requirements. Due to the special requirements of bridge and tunnel structures for driving comfort and safety, the pavement requires the construction of a precise elevation benchmark network to guide the operation of paving equipment in real time, thereby ensuring the uniformity of the asphalt mixture paving thickness and the smoothness of the longitudinal alignment. Traditional elevation acquisition methods usually rely on manual operation of laser transmitters for dynamic benchmark positioning. Although this technical solution can meet basic construction measurement needs, it has significant efficiency bottlenecks in practical applications: operators need to frequently adjust the position of the laser transmitter according to the paving progress, which not only forces the construction process to be interrupted, but also easily prolongs the equipment repositioning time due to the limited movement path of personnel in complex bridge and tunnel environments. Especially for long-span bridges or long tunnel projects, the traditional manual movement of laser transmitters is difficult to adapt to the technical requirements of rapid synchronous updating of the elevation benchmark in continuous paving operations. This not only increases construction time costs, but may also affect the accuracy of elevation transfer due to human operation errors, ultimately restricting the overall improvement of bridge and tunnel pavement quality and construction efficiency. Summary of the Invention
[0003] The purpose of this invention is to provide a 3D paving elevation information acquisition system that can improve the efficiency of elevation information acquisition and reduce construction time costs.
[0004] To achieve the above objectives, a 3D paving elevation information acquisition system is provided, comprising a first positioning module, a second positioning module, a laser transmitter, and a laser receiver. The laser transmitter is mounted on an electrically controlled rotating platform that can be vertically rotated and adjusted. The electrically controlled rotating platform and the first positioning module are mounted on an intelligent paver and electrically connected to a first controller on the intelligent paver. The laser receiver and the second positioning module are mounted on an electric control trolley and electrically connected to a second controller on the electric control trolley. The first controller and the second controller are respectively connected to a central controller through a first communication module and a second communication module.
[0005] Furthermore, the first positioning module and the second positioning module are either GPS positioning modules or GNSS positioning modules.
[0006] Furthermore, the electrically controlled rotation platform includes a rotation motor and an angle sensor. The rotation motor is used to control the rotation angle of the laser emitter, and the angle sensor is used to collect the rotation angle of the laser emitter. Both the rotation motor and the angle sensor are electrically connected to the first controller.
[0007] Furthermore, the rotary motor is either a stepper motor or a servo motor.
[0008] Furthermore, the electric control vehicle is remotely connected to a handheld terminal via a communication module, and the handheld terminal is used to control the movement of the electric control vehicle.
[0009] Principles and advantages:
[0010] 1. The technical solution presented in this paper significantly improves the efficiency and accuracy of bridge and tunnel pavement construction by constructing an intelligent, collaboratively controlled elevation information acquisition system. Specifically, the combination of an electrically controlled rotating platform and an intelligent paver enables automatic adjustment of the laser emitter, reducing manual intervention. Furthermore, the laser receiver and positioning module on the electrically controlled trolley allow for mobile measurement, avoiding frequent position adjustments. This improves the efficiency of elevation information acquisition and reduces construction time costs.
[0011] 2. By integrating spatial coordinates through dual positioning modules, while maintaining continuous acquisition of elevation benchmark signals by the laser receiver, the measuring device achieves autonomous path planning and precise position maintenance in complex bridge and tunnel environments, effectively overcoming the limitations of manual operation in terms of movement path.
[0012] 3. The centralized controller's centralized scheduling of each subsystem not only ensures real-time synchronization between the elevation benchmark network and the paving equipment's operating status, but also optimizes the stability of the elevation transfer process through closed-loop feedback of multi-source positioning data. The entire system, through collaborative operation between equipment, significantly shortens the response time for elevation benchmark reconstruction while ensuring the uniformity of asphalt paving layer thickness and longitudinal alignment accuracy. This is particularly suitable for the high-precision quality control requirements of continuous paving operations in long-span bridges and long tunnel projects. Attached Figure Description

The laser transmitter is mounted on an electrically controlled rotating platform that can be adjusted vertically. The electrically controlled rotating platform and the first positioning module are mounted on the intelligent paver and electrically connected to a first controller on the intelligent paver. The laser receiver and the second positioning module are mounted on an electric control trolley and electrically connected to a second controller on the electric control trolley.

[0017] The first and second positioning modules are either GPS or GNSS positioning modules. In this embodiment, a GNSS positioning module is selected. The electrically controlled rotating platform includes a rotating support, a rotating motor, and an angle sensor. The laser emitter, rotating motor, and angle sensor are all mounted on the support. The rotating motor controls the rotation angle of the laser emitter, and the angle sensor collects the vertical rotation angle of the laser emitter. Both the rotating motor and the angle sensor are electrically connected to the first controller. The rotating motor is either a stepper motor or a servo motor. In this embodiment, a stepper motor is selected. The electric control trolley is remotely connected to a handheld terminal via a communication module. The handheld terminal controls the movement of the electric control trolley. A conventional communication module can be used, such as a long-range 4G / 5G communication module, or a short-range Bluetooth or WiFi communication module. One or more combinations can be selected based on the site requirements.
[0018] In this solution, the electric control vehicle is a conventional four-wheeled remote-controlled vehicle, remotely controlled via a handheld terminal. The rotating motor, angle sensor, laser emitter, and laser receiver can all be assembled using components purchased through conventional channels. The first and second controllers utilize conventional microcontrollers, such as the 51 series, STEM32 series, or ESP32 series microcontrollers. This embodiment preferably uses the ESP32 series microcontroller due to its compact size and built-in Bluetooth and WiFi communication capabilities. The central controller is a conventional server, used to analyze and calculate elevation data from the collected positioning data and angle sensor angle data.

The combination of an electrically controlled rotating platform and an intelligent paver enables automatic adjustment of the laser emitter, reducing manual intervention. Furthermore, the laser receiver and positioning module on the electrically controlled trolley allow for mobile measurement, avoiding frequent position adjustments.
