Description

Technical Field

[0001] This invention belongs to the field of infrared thermometer technology, and specifically relates to an infrared temperature acquisition instrument for suspension bridge cable strands. Background Technology

[0002] Real-time monitoring of cable strand temperature is crucial during the construction of the main cable of a suspension bridge, ensuring that the bridge's alignment and internal forces meet design requirements. Accurate acquisition of cable strand temperature data provides a scientific basis for cable adjustment schemes, effectively improving the precision and efficiency of main cable erection, and thus promoting the intelligent and digital development of main cable construction. Currently, this vital data collection relies primarily on two traditional methods: one is on-site sampling using handheld infrared thermometers by construction workers; the other is indirectly obtaining ambient temperature by deploying temperature and humidity sensors in the construction area. Both methods have significant limitations and cannot meet the high standards of construction quality control required for modern long-span suspension bridges.

[0003] Specifically, manually holding a temperature gun is not only time-consuming, labor-intensive, and inefficient, but also fails to achieve continuous, synchronous, and real-time temperature monitoring, resulting in significant data gaps in both time and space. While deploying fixed environmental sensors can acquire continuous data, the limitations of sensor installation location and orientation mean that the measured data are typically macroscopic atmospheric temperature or local ambient temperature, which differs significantly from the true surface temperature of the cable strands. Because the cable strands are affected by various factors such as solar radiation, wind speed, and self-heating, their temperature field distribution is complex. Ambient temperature alone cannot accurately reflect the actual state of the cable strands, directly impacting the accuracy of temperature correction and alignment control, and failing to meet the requirements of high-precision construction analysis. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this invention is to provide an infrared temperature acquisition device for suspension bridge cable strands. By incorporating grooves, anti-slip rubber, and an angle adjustment plate, the device is fixed to the gantry column using cable ties passing through the grooves. The anti-slip rubber enhances the anti-slip effect and ensures stable fixation. Adjusting the angle adjustment plate aligns the infrared temperature sensor with the cable strand being measured, increasing measurement flexibility and ensuring accurate temperature readings.

[0005] The technical solution of the present invention is as follows: an infrared temperature acquisition device for suspension bridge cables, comprising an acquisition device body, the acquisition device body being a shell structure, a panel on the front end of the acquisition device body, an OLED display screen, an infrared temperature measuring hole, a reset button, and a power switch button arranged sequentially on the panel, a vertical steering column in the middle of the rear end panel of the acquisition device body, the vertical steering column being rotatably connected to an angle adjustment plate, a circuit board and a lithium battery inside the acquisition device body, multiple operation buttons on the front end panel below the OLED display screen, an infrared temperature sensor inside the infrared temperature measuring hole, and the infrared temperature sensor, lithium battery, OLED display screen, reset button, and power switch button being respectively connected to the circuit board.

[0006] The front panel of the data acquisition device body has screw grooves around its perimeter, and screws are installed in the screw grooves. The circuit board inside the data acquisition device body is fixedly connected to the inside of the data acquisition device body by screws, and buffer pads are installed in the screw grooves.

[0007] The front panel has grooves on both the top and bottom sides where it connects to the main body of the data acquisition device.

[0008] The groove surface is covered with anti-slip rubber.

[0009] The data acquisition device has a charging port and a data reading interface on its side. The charging port is connected to the lithium battery, and the edges of the charging port and the data reading interface are provided with waterproof sealing rings.

[0010] Both the charging port and the data reading interface are Type-C interfaces.

[0011] The circuit board is a PCB board, which integrates an infrared temperature measurement module, a data processing module, a data storage module, and an Internet of Things module. The modules are connected by circuits to realize data acquisition, processing, storage, and transmission.

[0012] The technical advantages of this invention are as follows: 1. By incorporating grooves, anti-slip rubber, and an angle adjustment plate, the data acquisition device is fixed to the gantry column using cable ties through the grooves during use. The anti-slip rubber enhances the anti-slip effect, ensuring stable fixation. Adjusting the angle adjustment plate aligns the infrared temperature sensor with the measured cable strand, increasing measurement flexibility and ensuring accurate temperature measurement. 2. The data acquisition device itself contains a circuit board integrating a data processing module, a data storage module, and an IoT module. The data processing module analyzes temperature fluctuations during measurement, eliminating the influence of catwalk swaying on temperature. The data storage module stores temperature data locally, ensuring data integrity in case of power failure or network outages.
