Abstract
Description
Technical Field
[0001] This utility model relates to a tilt detection device, and more particularly to an integrated tilt detection device suitable for signal towers. Background Technology
[0002] In the current communications field, signal towers are often used as the mounting medium to ensure unobstructed installation of communication equipment. Currently, signal towers often need to support a large amount of equipment, which may exceed the tower's weight-bearing capacity, causing ground subsidence. Simultaneously, uneven load distribution can lead to tower tilting. Prolonged exposure to a tilted state can easily cause the tower to collapse.
[0003] Currently, conventional tilt detection methods mainly rely on on-site mechanical structure measurements or on-site image processing of the signal tower for estimation. These methods can only provide a vague sense of tilt, resulting in low accuracy. Furthermore, they require multiple external cameras mounted on the signal tower and image processing technology, leading to high implementation costs. They also encroach on the mounting space of communication equipment, which can easily obstruct the cameras, affecting the accuracy of image data acquisition and processing. Moreover, they require independent power supply lines to the signal tower, increasing energy consumption.
[0004] Furthermore, conventional testing equipment can only perform on-site testing and cannot provide remote or local synchronous alarms when anomalies occur, thus failing to meet the requirements for real-time detection and rapid access processing.
[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create an integrated tilt detection device suitable for signal towers, making it more valuable for industrial applications. Utility Model Content

[0027] Detailed Implementation
[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0029] like Figures 1 to 3An integrated tilt detection device suitable for signal towers includes a die-cast aluminum alloy housing 1, with a cover 27 mounted on the housing. Its unique feature is the inclusion of a shock-absorbing bracket within the housing 1, on which are integrated a three-axis MEMS gyroscope module 2, a 4G DTU wireless transmission module 3, a wind speed and direction sensor 4, a temperature sensor 5, and a main control device 6. This design prevents direct impact on the internal sensors and modules from strong winds or heavy rain, even at higher installation locations. During operation, the three-axis MEMS gyroscope module 2 connects to the main control device 6 via an I2C bus, and the 4G DTU wireless transmission module 3 connects to the main control device 6 via an RS-485 interface. This allows the 4G DTU wireless transmission module 3 to upload data such as the signal tower's tilt angle, wind speed and direction, temperature, and location to a cloud platform for remote monitoring by the user. Meanwhile, to improve the accuracy of wind speed, direction, and temperature data acquisition, a detection channel 7 is opened on the side of the aluminum alloy housing 1, and the probes of the wind speed and direction sensor 4 and the temperature sensor 5 are respectively installed in the detection channel 7. During actual assembly, the probe of the wind speed and direction sensor 4 can be appropriately exposed above the detection channel 7 to avoid undue obstruction. For special detection needs in certain extreme operating environments, the probe of the temperature sensor 5 can be inserted into a pre-reserved positioning slot or positioning hole on the signal tower to more accurately sense the actual temperature of the signal tower, thereby assisting in the identification of potential metal fatigue hazards in extreme high or low temperatures. Furthermore, considering the power supply needs under normal use, this invention installs a solar panel 8 at the upper end of the aluminum alloy housing 1, and an integrated battery module 10 with an integrated inverter 9 is also installed inside the aluminum alloy housing. The solar panel 8 is connected to the integrated battery module 10 through an anti-reverse current diode 11 (model 1N5408), and the integrated battery module 10 is connected to the main control device 6. This can meet the solar power supply needs under normal operating conditions. During implementation, battery modules of different capacities can be selected according to the local climate to meet energy supply needs under non-sunlight conditions and ensure stable operation throughout the year. Furthermore, considering the ability to trigger local anomaly alarms during local inspections, this invention includes an audible and visual alarm device consisting of a buzzer 12 and an LED warning light 13 installed at the lower end of the aluminum alloy casing 1. This audible and visual alarm device is connected to the main control device 6. If the installation angle and latitude are taken into account, an adjustment bracket can be added to the solar panel 8 to adjust its orientation.
[0030] According to a preferred embodiment of this utility model, to facilitate modular assembly, the shock-absorbing bracket includes several guide posts 14 distributed inside the aluminum alloy shell 1. Each guide post 14 is fitted with a silicone shock-absorbing pad 15, with a hardness of 50±5 Shore A. This ensures stable mounting and prevents abnormal collapse. Simultaneously, the front end of the silicone shock-absorbing pad 15 is connected to a bracket plate 16, which has several mounting slots 17. After assembly, the three-axis MEMS gyroscope module 2, the 4G DTU wireless transmission module 3, the wind speed and direction sensor 4, the temperature sensor 5, and the main control device 6 are respectively installed in their corresponding mounting slots 17. Of course, the number of mounting slots 17 can be greater than the actual number of modules occupied, facilitating subsequent functional expansion. Considering the shock absorption requirements during daily use, the thickness of the silicone shock-absorbing pad 15 is 0.5 to 1.5 cm; the sides of the silicone shock-absorbing pad 15 have several V-shaped shock-absorbing grooves 18. In this way, the stress can be absorbed first through the damping groove 18, reducing the large-scale shaking of the silicone damping pad 15 itself. Furthermore, considering the stability of the connection, the bracket plate 16 and the silicone damping pad 15 are connected by countersunk screws 26.
[0031] Furthermore, to ensure stable signal transmission, an antenna assembly is connected to the 4G DTU wireless transmission module 3. Specifically, the antenna assembly used in this invention includes a base 19 threadedly connected to the aluminum alloy housing 1, and an omnidirectional antenna 20 connected to the base 19. The omnidirectional antenna 20 also has an independent conductive line that passes through the base 19 and is electrically connected to the 4G DTU wireless transmission module. Moreover, an insulating sleeve made of polytetrafluoroethylene is distributed on the inner wall of the base 19 to prevent electromagnetic interference from the integrated battery assembly 10.
[0032] In practical implementation, the main control device 6 includes an integrated circuit board with a microcontroller component mounted on it. The input of the microcontroller component is connected to a second-order low-pass filter circuit. For stability, the edge of the integrated circuit board is connected to the support plate 16 of the shock absorber bracket via positioning screws. Furthermore, the integrated circuit board can be pre-set with communication and power supply interfaces for connecting various components such as the wind speed and direction sensor 4 and the temperature sensor 5, facilitating convenient docking and meeting the needs of modular assembly.
[0033] Meanwhile, both the wind speed and direction sensor 4 and the temperature sensor 5 are connected to the main control device 6 via differential amplifier circuits, with an adjustable gain range of ±10%, improving data acquisition accuracy. To facilitate real-time sensing of wind speed changes, a ceramic-based thermal wind speed and direction sensor 4 can be used. Alternatively, commercially available Nanhua FA213 wind speed and direction sensor 4 and Texas Instruments LM35 temperature sensor 5 can be directly used.
[0034] Furthermore, to better determine the current location of the signal tower and facilitate targeted data monitoring and maintenance, a GPS component 21 is installed on the shock-absorbing bracket. The GPS component 21 is connected to the main control device 6. Specifically, the GPS component 21 is connected to a patch ceramic antenna 22, and a clearance hole 23 is provided at the bottom of the aluminum alloy housing 1, into which the patch ceramic antenna 22 is embedded. This prevents the presence of the aluminum alloy housing 1 from interfering with the communication of the GPS component 21.
[0035] During use, to facilitate convenient and stable installation, this invention features a clamp assembly 24 installed on one side of the aluminum alloy housing 1, with polyurethane pads 25 distributed around the inner ring of the clamp assembly 24. This allows the polyurethane pads 25 to contact the signal tower frame during locking, filling any potential tolerances and facilitating stable positioning. Additionally, several anti-slip mesh strips are distributed on the surface of the polyurethane pads 25. This provides better cushioning and wear resistance, meeting the needs of long-term clamp attachment. As can be seen from the above description and accompanying drawings, this invention offers the following advantages:
[0036] 1. It possesses moderate seismic resistance, effectively absorbing external stress impacts (such as strong winds and heavy rain), ensuring the stable operation of high-precision devices such as three-axis MEMS gyroscope modules and 4G DTU modules. Furthermore, the seismic-resistant structure features a modular installation method, making installation and use convenient.
[0037] 2. It can achieve coordinated monitoring of signal tower parameters, meet the high-precision acquisition of multi-dimensional data such as tilt angle, wind speed, and temperature, and realize comprehensive monitoring under various working conditions.
[0038] 3. It can achieve long-term independent power supply, employing a hybrid power supply system of solar panels and integrated battery modules (including inverters). Charging and discharging are controlled by an anti-reverse current diode (1N5408), supporting the selection of batteries with different capacities. This design ensures continuous power supply under non-sunlight conditions, adapts to extreme climate environments, and achieves uninterrupted operation throughout the year.
[0039] 3. It can meet the dual early warning mechanism of remote and local operation. Real-time remote monitoring can be achieved using a cloud platform and local programs. Simultaneously, it is equipped with a local audible and visual alarm device, forming a dual early warning system from the cloud and on-site.
[0040] 4. Excellent anti-interference and enhanced signal stability. The antenna assembly adopts an omnidirectional antenna and a PTFE insulating sleeve design, effectively shielding electromagnetic interference; GPS signals are transmitted unobstructed through special openings in the metal casing.
[0041] 6. Easy Installation. The clamp assembly has built-in polyurethane pads and anti-slip mesh strips, adapting to different tower size tolerances and ensuring stable installation.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
