[0025] In the following description, many specific details are set forth in order to provide a thorough understanding of the application, but the application can also be practiced without the other ways different from the description, and those skilled in the art can make similar generalization without departing from the spirit of the application, therefore the application is not limited to the specific embodiments disclosed below.

[0026] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. The application provides the following embodiments.

[0027] As Figure 1As shown in the figure, it is the structure diagram of the tower foundation settlement monitoring device based on Beidou system in the embodiment. The monitoring device can stably detect the settlement of the tower and detect the shaking frequency of the tower. When the shaking frequency is too high, the staff can be automatically prompted to check the data of the tower, so as to ensure the safety and working quality of the monitoring device during use. The monitoring device comprises a detection box 1, a control assembly 2 and a control box door 3. The control assembly 2 is installed in the detection box 1. The control assembly 2 accurately detects the horizontal angle and settlement data of the tower. The control box door 3 is installed at the opening of the side surface of the detection box 1. The control box door 3 closes and shields the whole detection box 1. The balance detection mechanism 4 for detecting the shaking frequency of the tower is installed in the detection box 1. The photovoltaic panel 6 is installed on the upper surface of the detection box 1. The photovoltaic panel 6 converts solar energy into electric energy for the operation of the whole monitoring device.

[0028] As shown in the figure, Figure 2 As shown in the figure, it is the structure diagram of the control assembly 2 in the embodiment. The control assembly 2 comprises a GNSS assembly 21, a measurement type GNSS antenna 22 and a DTU device 23. The detection box 1 is installed with a partition plate. The GNSS assembly 21 is installed on the upper surface of the partition plate. The GNSS assembly 21 adopts an existing GNSS receiver. The measurement type GNSS antenna 22 electrically connected with the GNSS assembly 21 is installed on the side wall of the detection box 1. The data received by the measurement type GNSS antenna 22 is input into the measurement type GNSS antenna 22. The DTU device 23 is symmetrically installed on the upper surface of the partition plate and located on both sides of the GNSS assembly 21. The DTU device 23 adopts an existing data transmission unit in the industrial field. One group of DTU devices 23 is electrically connected with the GNSS assembly 21. The control system 24 for transmitting and receiving data of the Beidou system is installed in the detection box 1. The control system 24 transmits the observation data to the calculation and disaster prevention monitoring platform in real time through the public network. The data platform establishes a real-time state model of the tower by using the calculation data. The real-time state is compared with the original state. Whether the tower is deformed and the degree of deformation are judged according to the offset of the two.

[0029] As shown in the figure, Figure 3 and Figure 4As shown, it is the structural schematic diagram of the balance detection mechanism 4 in the embodiment, which comprises a side wall 41, a connecting ring 42 and a shaking support plate 43. The side wall 41 is installed in the inside of the detection box 1 and is a cylinder structure with an open top. The connecting ring 42 is installed in the side wall 41, and the shaking support plate 43 is installed in the connecting ring 42 and is a conical structure. The metal ball 44 is arranged in the shaking support plate 43. The detection assembly 45 is installed on the inner wall of the side wall 41 and cooperates with the metal ball 44 to realize circuit communication. The counting and timing assembly 46 is installed on the inner wall of the detection box 1 below the side wall 41 and is electrically connected with the detection assembly 45. During use, the detection box 1 installed on the iron tower shakes as the iron tower shakes, driving the metal ball 44 to roll in the shaking support plate 43. When the shaking frequency is small, the metal ball 44 cannot roll out of the conical inner wall of the shaking support plate 43, and the shaking data has little effect on the final measurement data. When the shaking frequency is too large, the metal ball 44 rolls out of the shaking support plate 43 and enters the side wall 41. The metal ball 44 contacts the detection assembly 45, driving the circuit in the detection assembly 45 to close and driving the counting and timing assembly 46 and the detection assembly 45 to work. The frequency and speed of the shaking of the metal ball 44 are detected. The iron tower shakes back and forth, and the metal ball 44 also swings left and right in the side wall 41 at the same frequency. The metal ball 44 contacts the detection assembly 45 on the two sides of the inner wall of the side wall 41 alternately. Each time the metal ball 44 contacts the detection assembly 45, the circuit in the counting and timing assembly 46 is connected, and the counting and timing assembly 46 performs counting and timing processing. With the left and right shaking of the metal ball 44 and the alternating contact of the metal ball 44 with multiple detection assemblies 45, the counting and timing assembly 46 can calculate the frequency of the shaking of the metal ball 44 and the time of single shaking. The data are used to stabilize the iron tower for detection and processing.

[0030] It is worth noting that when the iron tower itself tilts, the metal ball 44 will shift to one side, allowing the metal ball 44 to contact one set of detection assemblies 45 for a long time. At this time, the counting and timing assembly 46 is in a long-time running state. This data is transmitted to the control system 24, which is convenient for timely reflection to the operator, so that the operator can detect and maintain.

It is worth noting that the contact part between the indicator lamp electrode piece 453 and the counting electrode piece 452 and the metal ball 44 in the embodiment is provided with a groove, and the outer surface of the metal ball 44 is stably attached to the inner wall of the groove, so as to ensure the stability of the circuit closing of the indicator lamp electrode piece 453 and the counting electrode piece 452.

[0032] The arc-shaped chamfers are arranged between each group of concave frames 451 in the embodiment, so as to avoid the situation that the metal ball 44 is stuck in the gap at the connection position of each group of concave frames 451, and the metal ball 44 can roll into the concave frame 451 on the side along the inner wall of the chamfer, so as to assist the stable operation of the device.
