Embodiment approach

[0046] Implementation method: such as figure 1 , 2 As shown, the UAV-based T-beam construction tracking system includes an RFID tag installed on each T-beam, a UAV, a ground control center, and a terminal server, wherein the UAV is used to collect the T-beams. The beam information is sent to the ground control center; the drone is equipped with a camera, a Beidou positioning module, an altitude sensor, an inertial navigation module, an RFID UHF card reader, a data transparent transmission module, a buzzer and a main board; The RFID tag is used to store the corresponding T-beam data, and is identified by the RFID UHF card reader on the drone; the ground control center is used to receive the video stream and Beidou positioning data sent by the drone, Timestamp, RFID tag number information and process, and send control command information to the UAV, upload data to the terminal server; the ground control center is equipped with a human-computer interaction App; the terminal serv...

Embodiment

[0050] Example: such as image 3 As shown, this UAV-based T-beam construction tracking method is realized through the UAV-based T-beam construction tracking system described in the above-mentioned implementation mode. Taking the 25mT beam as an example, the specific method flow is as follows:

[0051] (1) An RFID tag with a unique number is fixed on each T-beam stored on the site;

[0052] Specific to this embodiment, the RFID tag can be fixed on the surface of the T beam after the 25mT beam is prefabricated;

[0053] (2) The ground control center makes a corresponding route and time plan for each T-beam, and displays it on the human-computer interaction app in the form of a Gantt chart; so that each T-beam has an appropriate transportation and installation plan;

[0054] (3) The UAV has received the number of the T-beam to be worked, flies into the T-beam site according to the flight plan, uses the airborne RFID UHF card reader to read the T-beam information, and locates the...

Abstract

The present invention relates to a UAV-based T-beam construction tracking system and method. The system includes an RFID tag on the T-beam, a UAV, a ground control center, and a terminal server. The UAV also includes a data transparent transmission module, Beidou positioning system, camera, altitude sensor, RFID UHF card reader, buzzer. In the method, the unmanned aerial vehicle recognizes and extracts the T-beam information by reading the number on the RFID tag, starts KCF target tracking to carry out the transportation and construction tracking of the T-beam, and sends information such as video stream, position, time, and number to the ground In the control center, the ground control center sends commands to the UAV to manage the T-beam construction according to the information. The present invention can realize the real-time positioning and position information monitoring of the T-beam, and analyze and process the relative positional relationship between the adjacent facilities and objects of the T-beam, track and guide specific targets for the transportation and installation of the T-beam, and improve the refinement in construction Level of control and security assurance.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle and road and bridge construction, in particular to a T-beam construction tracking system and method based on an unmanned aerial vehicle. Background technique [0002] Prestressed T-beams play an important role in highway and bridge construction. They have the characteristics of high strength, small dead weight, saving steel and durability, and have a wide range of applications. During the installation and construction of the T-beam, it is necessary to transport the T-beam from the beam storage site to the construction site through the beam transporter, and then the crane lifts the T-beam and puts it into the bridge erecting machine. Fine-tuning makes the position accurate. The use of mechanical girder flat cars to transport T-beams and erection machines to erect T-beams has always been a process with a high incidence of accidents in the bridge construction process. [0003] In th...
