DETAILED DESCRIPTION

[0037] The present embodiment proposes a self-powered data acquisition and transmission device based on a pole tower impact response measurement test, comprising: a data acquisition module 1 and a data receiving module. The data acquisition module 1 is used to collect analog electrical signals from the top of the pole tower, and the data acquisition module 1 is also used to convert the analog electrical signals into optical signals.

[0038] The data receiving module is connected to the data acquisition module 1 via an FC optical fiber. The data receiving module is used to obtain the optical signal, convert the optical signal into an electrical signal, and then output it.

[0039] Thus, in this embodiment, in the process of collecting tower measurement data, by separating the data acquisition module 1 from the data receiving module, it is convenient for the data acquisition module 1 to be installed near the top of the tower, so as to collect tower measurement data at close range to overcome electromagnetic interference and other problems, and ensure the accuracy of data collection; it is also convenient for the data receiving module to be set at a distance from the tower to ensure the safety of the operator. The solar self-powered system it carries not only realizes environmental protection but also reduces the workload of frequent battery replacement, ensuring the long-term operation of the device. At the same time, the data transmission from the data acquisition module 1 to the data receiving module is realized through the FC optical fiber, which solves the problems of data attenuation and data deformation caused by electromagnetic interference that may occur in long-distance data transmission, and ensures the reliability of data transmission, thereby ensuring the reliability of the data acquisition module 1 and the data receiving module being set separately.

[0040] In this embodiment, the data acquisition module 1 includes a packaging layer 11, a data acquisition unit 12, a photoelectric conversion unit 13, a battery pack 14 and a controller 15. The packaging layer 11 adopts a double-layer structure, with a solar cell panel 112 on the outside and a metamaterial absorbing structure layer 113 on the inside. The data acquisition unit 12, the photoelectric conversion unit 13 and the battery pack 14 are all installed in the packaging layer 11.

[0041] The storage battery 11 is also provided with an analog signal interface 16 connected to the data acquisition unit 12 and an optical fiber interface 17 connected to the photoelectric conversion unit 13. The analog signal interface 16 adopts a BNC receiving port.

[0042] The data acquisition unit 12 is connected to the photoelectric conversion unit 13. The storage battery 14 and the solar panel 112 are both connected to the data acquisition unit 12 and / or the photoelectric conversion unit 13 through the controller 15 for power supply. That is, in this embodiment, there are three ways to set the controller 15: the first way is that the controller 15 is connected to the battery 14, the solar panel 112 and the data acquisition unit 12 respectively, the battery 14 and the solar panel 112 supply power to the data acquisition unit 12 through the controller 15, and the photoelectric conversion unit 13 draws power from the data acquisition unit 12; the second way is that the controller 15 is connected to the battery 14, the solar panel 112 and the photoelectric conversion unit 13 respectively, the battery 14 and the solar panel 112 supply power to the photoelectric conversion unit 13 through the controller 15, and the data acquisition unit 12 draws power from the photoelectric conversion unit 13; the third way is that the controller 15 is connected to the battery 14, the solar panel 112, the data acquisition unit 12 and the photoelectric conversion unit 13 respectively, the battery 14 and the solar panel 112 supply power to the data acquisition unit 12 and the photoelectric conversion unit 13 at the same time through the controller 15. In specific implementation, the battery 14 and the solar panel 112 can be selected as the power supply.

[0043] In this embodiment, the controller 15 controls the power supply and disconnection of the battery 14 and the output power of the solar panel, thereby controlling the operation of the data acquisition module 1. In specific implementation, the controller 15 can be set on the packaging layer 11, and further the controller 15 can be set on the upper surface of the packaging layer 11 for easy operation.

[0044] During operation, the data acquisition module 1 collects the pole tower measurement data through the analog signal interface 16. The data acquisition module 1 processes the pole tower measurement data, such as analog-to-digital conversion. The photoelectric conversion unit 13 obtains the pole tower measurement data processed by the data acquisition unit 12 and converts it into an optical signal. After the data receiving module obtains the optical signal, it converts the optical signal into an electrical signal and outputs it to an external device such as a computer, which is convenient for the experimenter to operate.

[0045] In this embodiment, the encapsulation layer 11 adopts a double-layer structure, with the solar cell panel 112 on the outside and the metamaterial absorbing structure 113 on the inside. Figure 4 In this embodiment, the controller 15 controls the working state of the solar panel 112 and the switch of the battery pack 14 to realize power supply switching. The packaging layer 11 adopts a rectangular box structure. In the packaging layer 11, the data acquisition unit 12, the photoelectric conversion unit 13 and the battery pack 14 are distributed in a triangular shape to ensure the dispersion degree between the three and avoid local high heat in the data acquisition module 1.

[0046] Specifically, the self-powered data acquisition and transmission device based on the tower impact response measurement test in this embodiment has three working states:

[0047] In the first working state, the device is running and the sunlight intensity reaches the light intensity threshold, and the controller 15 is used to control the solar panel 112 to provide the electric energy required for the operation of the device. At this time, the right solar panel 112 directly supplies power to the device, that is, the solar panel 112 directly supplies power to the data acquisition unit 12 and / or the photoelectric conversion unit 13, thereby realizing efficient utilization of the electric energy converted from solar energy.

[0048] In the second working state, when the device is not running and the sunlight intensity reaches the light intensity threshold, the controller 15 is used to control the solar panel 112 to charge the battery pack 14. In this way, the waste of electric energy generated by the solar panel 112 when the device is not running is avoided, and the electric energy converted from solar energy is stored.

[0049] In the third working state, the device is running and the sunlight intensity does not reach the light intensity threshold, and the controller 15 is used to control the battery pack 14 to provide the electric power required for the operation of the device. In this way, the stability of the power supply and the reliability of the operation of the device are ensured.

[0050] In this embodiment, ventilation units consisting of a plurality of ventilation holes are respectively provided on two opposite side walls of the encapsulation layer 11. One ventilation unit is arranged in a herringbone shape with the data acquisition unit 12 and the storage battery 14, and the other ventilation unit is arranged in a herringbone shape with the photoelectric conversion unit 13 and the storage battery pack 14. In this way, the components in the storage battery 11 are prevented from blocking the ventilation holes 111, and the efficiency of air circulation and heat exchange between the storage battery 11 and the external environment through the ventilation holes 111 is effectively improved.

[0051] In this embodiment, the analog signal interface 16 and the optical fiber interface 17 are located on the same side wall of the packaging layer 11. The side wall where the analog signal interface 16 and the optical fiber interface 17 are located is located between the two ventilation units and on the side of the power supply unit 14 away from the data acquisition unit 12 and the photoelectric conversion unit 13. In this way, the wiring space of the cable connected between the data acquisition unit 12 and the analog signal interface 16 and the optical cable connected between the photoelectric conversion unit 13 and the optical fiber interface 17 is guaranteed.

[0052] In this embodiment, the cable connected between the analog signal interface 16 and the data acquisition unit 12 and the optical cable connected between the data acquisition unit 12 and the photoelectric conversion unit 13 are both straight cables to avoid bending, further ensuring the reliability of data acquisition.

[0053] The data acquisition and transmission device based on the tower impact response measurement test in this embodiment also includes an insulating platform 2 for providing an installation position for the data acquisition module 1 at the top of the tower. The top of the tower adopts a cross angle steel structure, such as Figure 5 Enlarged portion shown.

[0054] In this embodiment, the insulating platform 2 includes a mounting plate 21 and at least two bosses 22. The bosses 22 are arranged on the lower surface of the mounting plate 21, and the upper surface of the mounting plate 21 is used to install the data acquisition module 1. The height of the bosses 22 is equal to the height of the angle steel at the top of the tower. Figure 5 When the top of the tower shown in the enlarged part is shown, the boss 22 can be supported by the lower angle steel a of the cross angle steel structure, and the mounting plate 21 can be supported by the upper angle steel b of the cross angle steel structure, so that the boss 22 and the upper angle steel can be combined to achieve the following Figure 6 The installation effect shown ensures the stable installation of the insulating platform 2.

[0055] The installation plate 21 is provided with: a first through hole 23 for passing the tower crane line to hoist the insulating platform 2 to the top of the tower, a second through hole 24 for passing the binding line to bind and fix the insulating platform to the angle steel at the top of the tower, and a third through hole 25 for providing a mounting structure to fix the data acquisition module 1. In this way, when installing the insulating platform 2, the tower crane line can be passed through the first through hole 23, and then the insulating platform 2 can be hoisted to the top of the tower and installed as shown in the figure. Figure 6 and then pass the binding wire through the second through hole 24 to bind the insulating platform 2 to the cross angle steel; finally, fix the data acquisition module 1 on the insulating platform through the third through hole 25.

[0056] Specifically, in this embodiment, two through-hole matrices are symmetrically arranged on the mounting plate 21, and the through-hole matrix is ​​composed of second through-holes 24 distributed at the four corner points of the same rectangle. At least two second through-holes are also arranged between the two through-hole matrices on the mounting plate 21. The arrangement of the two through-hole matrices facilitates the symmetrical bundling of the insulating platform, and then cooperates with the two second through-holes 24 in the middle to ensure multi-point positioning of the insulating platform 2 and the cross angle steel, thereby ensuring stable installation of the insulating platform 2.

[0057] In this embodiment, an expansion screw is provided in the third through hole 25 to facilitate screw connection between the data acquisition module 1 and the insulating platform 2 .
