[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0032] See also Figure 1-Figure 3 This embodiment provides a bridge rotation visual monitoring system for bridge rotation construction, which includes a hardware monitoring module, an information display module and a rotation control module. The hardware monitoring module is used to collect relevant parameters during the rotation of the bridge 101; the information display module is electrically connected to the hardware monitoring module, and is used to obtain and display the relevant parameters; the rotation control module is electrically connected to the information display module or the hardware monitoring module, and is used to control the rotation state of the bridge 101 according to the relevant parameters.

[0033] The above scheme can detect the relevant parameters in the bridge rotation process in real time and feed back to the information display module, so as to have a more comprehensive understanding of the bridge rotation status, so as to take timely response measures and reduce construction risks.

[0034] The hardware monitoring module includes: an angle detection device 13 for detecting the rotation posture of the bridge 101, a tension sensor 11 for detecting the traction force of the traction device 100, a displacement sensor 12 for detecting the longitudinal displacement of the turntable support angle of the bridge 101, a wind speed sensor 15 for detecting the wind speed around the bridge 101, and a meter 14 for detecting the traction length of the steel strand 102 of the traction device 100; the angle detection device 13, the tension sensor 11, the displacement sensor 12 and the wind speed sensor 15 are all electrically connected to the information display module and the rotation control module, and the parameters detected by each are transmitted to the information display module and the rotation control module. The angle detection device 13 can use an electronic compass to accurately measure the actual rotation angle of the bridge, and the angle detection device 13 is set on the bridge 101.

[0035] The rotational posture of the bridge 101 includes a rotation angle, a transverse bridge inclination angle, and a longitudinal bridge inclination angle, and these parameters are all detected by the angle detection device 13 .

[0036] Further, the rotation control module includes a traction device 100 and a PLC control cabinet; the information display module or the hardware monitoring module is electrically connected to the PLC control cabinet, the PLC control cabinet is electrically connected to the traction device 100, and the traction device 100 is connected to the turntable of the bridge 101. The traction device 100 includes a continuous jack and a steel strand 102, one end of the steel strand 102 is clamped on the continuous jack, and the other end of the steel strand 102 is connected to the upper turntable of the bridge 101. The continuous jack pulls the steel strand to drive the turntable on the bridge to rotate. The traction device 100 can be set in multiples. In this embodiment, two traction devices 100 are set, wherein for a smaller bridge, the jack can also be replaced by a winder. Among them, the tension sensor 11 is set on the traction device 100, and the displacement sensor 12 is set on the turntable support angle of the bridge 101. The tension of the tension sensor 11 is relatively stable during the stable rotation of the bridge, but when the rotation is abnormal, the tension may change greatly, so the stability of the bridge rotation can be judged accordingly. The tension parameter is displayed in real time on the information display module. The meter 14 is fixed on the ground, and the meter wheel is in contact with the steel strand 102. The rotation angle of the bridge is indirectly obtained by measuring the length of the steel strand 102. It is known that the rotation meter 14 measures the arc length ΔL, the radius r of the lower turntable, and the rotation measurement angle The angle obtained by the calculation should theoretically be the same as the result measured by the angle detection device 13, and the measured arc length ΔL should theoretically be the same as the result measured by the displacement sensor 12. However, due to the different measurement positions, there must be a certain error. If the difference between the two is particularly large, it means that there is a high probability of a problem during the rotation process, so it can be used as a basis for judgment by the operator.

[0037] In order to ensure the safety of construction, the traction device 100 is provided with an interlocking shutdown module, and the PLC control cabinet is electrically connected to the interlocking shutdown module to control the traction device 100 to stop running. Specifically, during the bridge rotation process, if the transverse and longitudinal inclination angles of the bridge are detected to change by more than 0.5° or the wind force is greater than level 5, the PLC control cabinet immediately sends a command to the traction device 100 to suspend the rotation process. If the traction force of the traction device 100 is detected to exceed the theoretical calculated value, the PLC control cabinet immediately stops the traction device 100 and alarms to ensure the safe rotation construction.

[0038] Furthermore, the hardware monitoring module also includes: an aerial photography drone and / or a monitoring probe, which is electrically connected to the information display module to transmit the captured video images to the information display module. Specifically, the information display module uses BIM technology to form a three-dimensional model of the bridge 101 according to the relevant parameters for display. The three-dimensional modeling is driven by data measured by an electronic compass and a meter 14, and simulates the actual movement of the bridge in real time. The model has a background compensation function, and the driving data source can be manually selected and the compensation value can be manually input to compensate for the measurement deviation.

[0039] See also Figure 4 , the information display module is provided with a project overview module, a BIM rotating bridge three-dimensional model view module, a bridge posture data module, a traction equipment data module, a wind data module, a site monitoring and drone aerial photography module, and each module displays the corresponding data respectively. The monitoring probe is installed at a predetermined position on the construction site, and the aerial photography drone takes a bird's-eye view of the bridge in the air. The monitoring picture is uploaded to the cloud server via the wireless communication network. Use a computer to enter the URL, access the network platform of the bridge rotation information monitoring system and project it onto the on-site TV splicing wall. The network platform of the bridge rotation information monitoring system has a mobile terminal display function. Users can use mobile communication devices such as mobile phones and tablets to scan the QR code or visit the platform website to remotely view the construction monitoring situation. The display method of the information display module can be displayed on a display screen or projected, depending on actual needs.

[0040] In this embodiment, the sensors or electronic devices such as the electronic compass and meter counter 14 are all waterproof, eliminating the influence of special weather conditions such as line of sight obstruction, low visibility and rain on monitoring. Specifically, a waterproof structure can be set on the angle detection device 13, the tension sensor 11, the displacement sensor 12, the angle detection device 13, the meter counter 14 and the wind speed sensor 15.

[0041] In summary, the bridge rotation system provided in this embodiment monitors various parameters during the bridge rotation process by setting up a variety of detection devices, thereby reducing errors caused by instrument measurement and human operation, greatly improving the reliability of data; and can achieve uninterrupted real-time measurement, ensuring the real-time, consistency and accuracy of the measurement data. The sensor data is transmitted to the PLC control cabinet via wired transmission. The PLC control cabinet and the cloud server communicate through DTU, relying on 4G and GPRS, and can be used within the coverage range of the base station. The influence of building obstructions and complex terrain on the signal is eliminated, and the communication quality is reliable. The bridge rotation construction can be monitored in all terrains and all weather conditions.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
