[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an automated rotation operation continuous beam monitoring device, including a data acquisition unit and a control unit.

[0023] The data acquisition unit is arranged at the top of the beam to be rotated, and the beam has a rotation area when rotating; the control unit is arranged outside the rotation area, and the control unit is electrically connected to the data acquisition unit; the data acquisition unit includes a GNSS dynamic collector 10, a GNSS satellite antenna 20, a first data transceiver 30, a prism 40 and a horizontal device 50, the bottom end of the horizontal device 50 is connected to the beam, the top end of the horizontal device 50 is connected to the bottom end of the prism 40, the top end of the prism 40 is connected to the bottom end of the GNSS dynamic collector 10, the GNSS satellite antenna 20 is inserted on the GNSS dynamic collector 10, and the GNSS dynamic collector 10 is electrically connected to the first data transceiver 30. The control unit includes a total station measuring device 60, a second data transceiver 70 and a data feedback control center 80, the total station measuring device 60 is electrically connected to the second data transceiver 70, and the data feedback control center 80 is electrically connected to the second data transceiver 70. The control unit further includes a power supply 90 , which is electrically connected to the total station measuring device 60 , the second data transceiver 70 and the data feedback control center 80 .

[0024] First, a debugging instruction is issued to the data acquisition unit through the data feedback control center 80. After the debugging instruction is issued, it is wirelessly transmitted to the first data transceiver 30 of the data acquisition unit via the second data transceiver 70 of the control unit. The first data transceiver 30 sends the instruction to the GNSS dynamic collector 10 via the transmission line. After receiving the instruction, the GNSS dynamic collector 10 starts to execute it. After execution, the acquired satellite positioning data is transmitted to the data feedback control center 80 by the original route, and the debugging of the data acquisition unit is completed.

[0025] Secondly, a debugging instruction is issued to the total station measuring device 60 through the data feedback control center 80. After the debugging instruction is issued, it is transmitted to the total station measuring device 60 through the second data transceiver 70 of the control unit. After receiving the instruction, the total station measuring device 60 starts to execute it and performs positioning by automatically tracking the 360° prism. After positioning, the acquired positioning data is transmitted to the data feedback control center 80 by the original route, thus completing the debugging of the control unit.

[0026] Among them, when there is an abnormality in the two sets of data received by the data feedback and control center (the data of the same time period of the total station measuring device 60 and the GNSS dynamic collector 10 should be consistent), the verification instruction is started, and the verification instruction is issued and fed back in the same path as the debugging instruction. After the data feedback control center 80 receives the verification data, it analyzes and compares the data to see if it is abnormal. If the synchronization of the secondary verification data is abnormal, an early warning is issued.

[0027] The data feedback control center 80 uses software-assisted computers for operation and has intelligent management. The sending and receiving of relevant instructions does not require human intervention, and the results can be presented directly.

[0028] The GNSS dynamic collector 10 in the present application is the GNSS dynamic collector 10, and the GNSS satellite antenna 20 is the GNSS satellite antenna 20. It should be understood that GNSS, also known as the Global Satellite Navigation System, is an air-based radio navigation and positioning system that can provide users with all-weather 3D coordinates, speed and time information at any location on the earth's surface or near-earth space.

[0029] Before the beam body rotation operation, the control unit is arranged outside the rotation area, and the data acquisition unit is arranged on the central axis at both ends of the structural top surface of the beam body to be rotated.

[0030] A mounting hole is drilled at the center axis of the end of the top surface of the beam body, and the lower half of the horizontal device 50 is fixed in the mounting hole. After the horizontal device 50 is fixed, its top end is connected to the bottom end of the prism 40; the upper part of the prism 40 is connected to the bottom end of the GNSS dynamic collector 10. After the GNSS dynamic collector 10 is installed, the GNSS satellite antenna 20 and the transmission line are inserted into the corresponding interface and synchronously connected to the first data transceiver 30. The horizontal device 50 in this application refers to an adjustment device that can adjust the instrument to a standard horizontal position.

[0031] After the data collection unit is installed, the horizontal device 50 is leveled, the GNSS dynamic collector 10 is turned on (because the rotation operation time is short, there is no need to set up a separate power supply 90), and the display of the satellite positioning data collection signal light is tested.

[0032] After the GNSS dynamic collector 10 is set up, the signal light display of the first data transceiver 30 is checked for wireless transceiver function to see whether the satellite positioning data collected by the GNSS dynamic collector 10 is normal and whether the data sent is normal. The first data transceiver 30 does not need to be equipped with a separate power supply 90, and is powered by the GNSS dynamic collector 10 through the transmission line.

[0033] The 360° prism is tested to check its measurement accuracy.

[0034] After the data acquisition unit is installed, the control unit needs to be installed and debugged. First, the total station measuring device 60 is installed and set up, and the second data transceiver 70 is synchronously connected to the power supply 90 to test the data transmission with the total station measuring device 60 and the data feedback control center 80.

[0035] The data feedback control center 80 is the management and control center of the entire system, responsible for the final data solution and instruction issuance, processing and solution of the data transmitted by the second data transceiver 70, and after solution, judging and analyzing the data. It can also synchronously collect data from the GNSS dynamic collector 10 and issue measurement instructions to the total station measuring device 60, and set measurement mode and measurement time interval instructions.

[0036] The total station measuring device 60 is responsible for tracking and measuring the 360° prism, and the measured data is transmitted to the data feedback control center 80 via the second data transceiver 70 .

[0037] The data feedback control center 80 conducts a comprehensive analysis based on the data collected by the GNSS dynamic collector 10 and the data collected by the total station measuring device 60, and provides feedback on the rotation state of the beam (rotation trajectory, change in the beam posture) and rotation parameters (rotated angle, angle to be rotated, rotated arc length, arc length to be rotated, rotation angular velocity and linear velocity, etc.).

[0038] If an abnormality occurs synchronously in the two sets of data (generally set to the same measurement time interval, such as when rotating at a uniform speed, the measurement collection interval is 10s, and the time interval can be set arbitrarily in the inching mode), the verification instruction of the data feedback control center 80 is triggered to be issued, and the verification instruction is sent to the GNSS dynamic collector 10 and the total station measuring device 60 respectively. After the two components are verified respectively, the verification data is returned to the data feedback control center 80. If the verification data is still abnormal, an abnormal beam rotation warning is issued.

[0039] The GNSS dynamic collector 10 and the total station measuring device 60 can both collect the plane and elevation positioning coordinates of the structure in real time, and the second data transceiver 70 and the first data transceiver 30 are in wireless communication.

[0040] In summary, the utility model has the following beneficial effects:

[0041] 1. Compared with traditional manual measurement, it saves a lot of manpower, reduces the occurrence of human errors, improves measurement efficiency, reduces the safety risks of measurement personnel, and saves measurement costs;

[0042] 2. Compared with 3D modeling, its technical difficulty is greatly reduced, and a large number of beam measurement sensors are omitted, reducing the impact of the environment on measurement accuracy;

[0043] 3. The product has strong applicability, accurate and timely data analysis, and can wirelessly set the working mode or operation time to improve construction efficiency. When danger is found, it can quickly issue an early warning to improve the safety of construction. The total station measuring device 60, 360° prism, and GNSS dynamic collector 10 used by it are all common instruments used during the project construction period and can be reused.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model 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.
