DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1, reference Figures 1 to 4 , which is the first embodiment of the present invention, provides a transmission tower foundation horizontal displacement detection system, including a settlement detection module 100, which is arranged at the four tower corners of the transmission tower and is used to collect, process and send data; a laser leveling module 200, which is placed at the central pile of the transmission tower and emits infrared laser to the surroundings by scanning; and a portable host computer, which is used to remotely monitor the operating status information of the transmission tower.

[0034] Specifically, the settlement detection module 100 includes a light sensing unit, a data exchange unit and a power supply unit.

[0035] It should be noted that if Figure 1As shown, the system mainly includes three modules, namely, a light sensing module, a data interaction module, and a power supply module; the light sensing module mainly uses an infrared receiving tube 101 to collect the real-time height data of the tower angle of the transmission tower, and then uses a low-noise operational amplifier 104 to amplify the data, filter and denoise, and perform intelligent analysis and calculation. The power supply module is powered by a power chip and a lithium battery. The data interaction module processes and stores the data of the detection module by a microprocessor 102 and a data storage unit 105, which is then sent to the main control device by the self-organizing network module 103 and uploaded to a portable host computer. The portable host computer here can be a computer, mobile phone, tablet or other device implanted with corresponding system software;

[0036] The laser sweeping module 200 emits laser to provide a laser source for the settlement detection module 100, and the light sensing module of the settlement detection module 100 can collect data on the transmission tower after receiving the laser.

[0037] The handheld data terminal is mounted on a portable host computer, which is interconnected with the settlement detection device via WiFi through the self-organizing network module 103 to receive the tower data collected by the settlement detection device in real time. The collection device and the host computer build a self-organizing local area network. The real-time data is uploaded to the portable host computer for display through the WiFi self-organizing network module 103. The software deployment layer of the detection platform is mainly composed of the database deployed by the platform, the secure access server, etc., which is responsible for the security and stability of the data. It is developed and designed based on the IOT technology of edge computing, and its main functions include real-time data of tower tilt settlement, detection alarm, auxiliary decision-making, etc.

[0038] Example 2, reference Figures 1 to 5 This embodiment is different from the first embodiment in that the photosensitive unit collects the real-time height data of the transmission tower angle through the infrared receiving tube 101, and then amplifies the data, filters and removes noise, and performs intelligent analysis and calculation through the low-noise operational amplifier 104.

[0039] Specifically, the data exchange unit processes and stores the data of the detection module by the microprocessor 102 and the data storage unit 105, and then sends the data to the main control device through the self-organizing network module 103 and uploads it to the portable host computer.

[0040] Furthermore, the power supply unit is powered by a power chip and a lithium battery.

[0041] Furthermore, the infrared receiving tube 101 is used to quickly sense the infrared laser emitted by the laser leveling module 200 and start collecting tower data.

[0042] Furthermore, a portable host computer is used for edge computing of real-time data on tower inclination and settlement.

[0043] The rest of the structure is the same as that of Example 1.

[0044] Example 3, reference Figures 4 to 9 The present invention also provides a transmission tower foundation horizontal displacement detection device, including a detection member 300, including a settlement detection module 100 and a laser leveling module 200, a level meter 302 is provided at the end of the shell of the detection member 300, and the level meter 302 is used for on-site installation and calibration of the detection member 300; a bottom plate 305 bracket 301, and the bottom plate 305 bracket 301 is arranged at the bottom end of the transmission tower, and the specific structure is as follows Figure 4 shown.

[0045] Specifically, the bottom plate 305 bracket 301 is connected to the outer shell of the detection element 300, and the specific connection method is as follows: Figure 4 shown.

[0046] Furthermore, it also includes a fixed bracket 303, which includes a frame, a slider 304 and a support bolt. The slider 304 and the support bolt are both arranged on the frame, and the detection member 300 is arranged on the slider 304; one end of the support bolt is fixed to the bottom end of the transmission tower, and the other end of the support bolt is connected to the frame. The specific connection method is as follows: Figure 8 and Fig. 9 shown.

[0047] It should be noted that Figure 2 The figure shows the design process of the sensing node. After the detection component 300 is turned on and initialized, it will actively send a network configuration request to the detection platform. If the first request is unsuccessful, it will continue to wait for pairing. Once the detection platform turns on the Internet of Things, the network configuration will be successful, and the device will automatically connect to the platform and be in detection mode. At the same time, in order to save energy, if the laser scanning surface is not detected within 1 minute, it will automatically enter the standby mode and wait to be awakened. When the device captures the scanning surface, the device will be awakened immediately and collect the height data of each tower leg of the tower in turn. And the inclination value of the tower is calculated in real time based on the collected tower settlement data, and finally the data is compressed and packaged and sent to the detection platform through the WIFI Internet of Things to realize the detection of the inclination settlement value of the tower.

[0048] It should also be noted that if Figure 3 The following is the working flow chart of the transmission tower tilt and settlement detection platform. After the detection device collects the tower tilt and settlement data, the system will verify the sensor number. The network layer will store different data in different locations in the database according to the different sensor numbers, which is convenient for searching and reading at any time. Then the detection platform will parse the stored data message, analyze the data bits, and display the detected tilt and settlement values ​​in real time. And according to the abnormal alarm data, it will assist in making decisions on different measures.

[0049] The rest of the structure is the same as that of Example 2.

[0050] Operation process: The detection component 300 is a core component installed on each leg of the transmission tower. The detection component 300 integrates a light sensing module infrared receiving tube 101, a microprocessor 102, a communication module, a low-noise operational amplifier 104, and a data storage unit 105. The light sensing module infrared receiving tube 101 inside it will quickly sense the infrared laser emitted by the laser sweeping device and start to collect tower data. The collected data is first amplified, filtered, and denoised by the low-noise operational amplifier 104, and then processed by the microprocessor 102. The data is intelligently analyzed and calculated and stored in the data storage unit 105. Finally, the data is uploaded to the portable host computer through the communication module in the form of a self-organizing network. The portable host computer has functions such as edge computing, real-time data of tower inclination and settlement, detection and early warning, and expert decision-making, which is convenient for users to remotely obtain tower-related data and timely grasp the health and safety status of the tower.

[0051] The detection component 300 is installed on the four legs of the transmission tower, and can be directly supported on the legs of the tower by the base plate 305 bracket 301. The inside of the base plate 305 bracket 301 is riveted to the detection device shell and can be extended and rotated to adjust the position. There is a level 302 on the back of the detection component 300 shell for on-site installation and calibration to ensure that the base plate 305 bracket 301 of the detection component 300 is placed horizontally.

[0052] It is also possible to choose to install the detection member 300 by the installation bracket, that is, the detection member 300 is fixed on the slider 304 of the installation bracket, and slides through the slider 304 to better receive the infrared laser. One end of the triangular support stud 306 is fixed on the cement pile of the foot of the transmission tower, and the other end is fixed on the base plate 305 of the installation device.

[0053] The present invention has intelligent sensing technology, light sensing technology, edge computing technology, IOT technology, and expert decision-making technology, and is an integrated device composed of a detection module, a laser sweeping module 200, and a portable host computer. The detection device uses an embedded microprocessor chip, whose performance meets the system requirements, and adopts high-precision photosensitive nodes to capture small changes in the tower foundation; it has a wireless transmission function, and adopts a self-built local area network for networking, with stable data transmission and strong anti-interference ability, which improves the security and stability of data transmission, and adopts an intelligent algorithm of edge computing. At the same time, it intelligently gives detection warnings and provides expert decision-making assistance suggestions, forming an integrated system with real-time perception, holographic interconnection, autonomous warning, and decision-making assistance. The system has high system integration and can be remotely monitored in real time, which helps to help operation and maintenance personnel to grasp the operation status of the tower in time, avoid the expansion of problems, ensure the safe operation of the transmission line, and provide meaningful reference and reference for similar projects in the future.
