[0048] The geological disaster monitoring system and device provided by this utility model can be applied to utility poles to collect environmental data around the poles and information about the poles themselves. The following is a detailed description of the implementation method:

[0049] Example 1

[0050] Please refer to Figure 1 A geological disaster monitoring system includes an image acquisition module 1, an image processing module 2, a detection sensor 3, a Beidou positioning module 4, and a main control module 5. The input end of the image acquisition module 1 is connected to at least two cameras; for example, in this embodiment, five cameras are used. Four cameras are arranged around the geological disaster monitoring device, and the images captured by adjacent cameras can be combined to form a 180° view, and two 180° views can be further stitched together to form a 360° panoramic view. The third camera can be located at the bottom of the geological disaster monitoring device to obtain a view of the scene below, such as monitoring the environment below the tower base. By using five cameras for joint monitoring, a comprehensive, blind-spot-free monitoring effect is achieved, solving the problem that existing equipment cannot see the actual environment on-site. The output end of the image acquisition module 1 is connected to the input end of the image processing module 2, meaning that the image acquisition module 1 converts the acquired photoelectric signals into digital signals and sends them to the image processing module 2 for image stitching processing. Please refer to... Figure 2 as well as Figure 3In an optional implementation, the image acquisition module 1 uses a photoelectric digital-to-analog converter chip U39, and the image processing module 2 uses a video acquisition module interface J14. The photoelectric signal acquired by the photoelectric digital-to-analog converter chip U39 is converted into a digital signal and then transmitted to the main control module 5 via an FPC line through the video acquisition module interface J14 in the form of a MIPI signal interface.

[0051] The detection sensor 3 is used to collect environmental data. It includes a temperature sensor, a stress sensor, and a resolution sensor, which are used to collect data such as temperature, clamp stress, and tower tilt. Additional sensors can be added as needed to collect data. In an optional embodiment, the detection sensor 3 includes a LoRa unit, allowing the collected data to be transmitted to the main control module 5 via LoRa.

[0052] Please refer to Figure 4 as well as Figure 5 The BeiDou positioning module 4 is used to acquire positioning data; the BeiDou positioning module 4 includes a BeiDou positioning module and a positioning antenna; the positioning antenna is used to receive the positioning data; the output end of the positioning antenna is connected to the input end of the BeiDou positioning module. The BeiDou positioning module includes a BeiDou positioning unit, a status detection unit, and a reset unit; the input end of the status detection unit is connected to the positioning antenna; the output end of the status detection unit is connected to the status input end of the main control module 5. Figure 4 As shown, the status detection unit includes a status detection chip U27, which is connected to the positioning antenna through the antenna interface J9; the RTK_FLAGB_R pin is used as the antenna status detection pin, which is normally high, and if it is low, it indicates that the antenna is abnormal; the RTK_FEED_R pin is used as the antenna power control pin for power control; at the same time, the status detection unit is equipped with a surge protection diode and a filtering structure at the input terminal (ANT) of the antenna interface J9 to ensure safety and data accuracy.

[0053] The status output terminal of the main control module 5 is connected to the status input terminal of the BeiDou positioning unit; the status output terminal of the BeiDou positioning unit is connected to an indicator light; the data output terminals (URXD1 & UTXD1) of the BeiDou positioning unit are connected to the main control module 5. The reset unit is connected to the reset terminal of the BeiDou positioning unit; when the status detection unit detects an abnormality in the positioning antenna, it outputs a low level, and the main control module 5 controls the reset unit to automatically reset when the BeiDou positioning unit is powered on based on the low level. The BeiDou positioning module also includes a filtering unit; the filtering unit is connected to the power input terminal (VCC) of the BeiDou positioning unit.

[0054] like Figure 5 As shown, the Beidou positioning module includes a positioning chip U26, a reset pin (RESET_N) connected to a reset unit; the status output terminal (RTK_STAT) of the positioning chip U26 is connected to an indicator light (LED_GRN); the filtering unit consists of 5 capacitors connected in parallel, and a Zener diode ZD1 is also provided between the power input terminal (VCC) and the chip ground (GND4).

[0055] When the module is powered on, the chip automatically resets once, and there are no other external IOs to control the module reset pin. When the control chip U5 detects that the RTK-FLAGB-R antenna status detection pin is low, the control chip U5 will pull the RTK-FEED-R pin low, thereby disconnecting the 5V power supply output of the status detection chip U27 and reporting the antenna abnormality information to the platform via the network.

[0056] The specific positioning principle of Beidou positioning module 4 is as follows:

[0057] The BeiDou positioning module sends positioning data to the Continuously Operating Reference Stations (CORS), instructing the CORS to obtain the first coordinate A of the target system where the BeiDou positioning module 4 is located based on the positioning data. Specifically, after receiving the positioning data via its positioning antenna, the observation station sends it to the BeiDou positioning module, which then transmits the positioning data to the CORS station via wireless transmission methods such as 4G. Subsequently, the CORS station positions the target system based on the first coordinate A to obtain the second coordinate B. Specifically, after performing network adjustment on the coordinate system corresponding to the first coordinate A, the observation station is positioned again based on the CORS in that coordinate system to obtain the three-dimensional coordinate B of the observation station. Coordinate correction is performed using the first coordinate A and the second coordinate B to obtain the coordinate values ​​of the target system. For example, comparing the two coordinates can correct the actual initial coordinates of the mobile station, and the changes in coordinates obtained by the BeiDou positioning module can be used to monitor the deformation of its location. For example, if the displacement exceeds a preset threshold, the terminal will issue a warning to the platform. Meanwhile, when the antenna is short-circuited, the antenna status detection pin outputs a low level, indicating that the antenna is abnormal. At this time, the module will automatically reset when it is powered on.

[0058] Please refer to Figure 6 as well as Figure 7 The main control module 5 uses a control chip U5 with integrated wireless communication functionality, or it can achieve communication functionality through a communication chip; the communication unit includes at least two different types of antenna interfaces, such as... Figure 7As shown, a 4G main antenna interface, a 4G diversity antenna interface, and a WiFi & BT antenna interface are respectively provided. The main control module 5 transmits data to the monitoring center 7 through the antenna interface. That is, the main control module 5 integrates and processes the image / video data, the data collected by the detection sensor 3, and the positioning data of the Beidou positioning module 4, and then transmits them wirelessly to the monitoring center 7 through the communication unit.

[0059] Please refer to Figure 8 as well as Figure 9 The system also includes a power-on module and operating status indicator lights. The power input terminals (VBUS & VBAT) of the power-on module are connected to a power source. The control input terminal (PWRKEY) of the power-on module receives switch signals. The control output terminal of the power-on module is connected to the power-on control terminal of the main control module 5. The operating status indicator lights (D6 & D7) are connected to the operating status output terminal (VIO18_PMU) of the main control module 5. For example, the control input terminal may have a button; pressing the button powers on the module, and a high-level output from the main control module 5 illuminates the operating status indicator lights.

SMP connectors are used to connect to the corresponding circuit modules, making the antenna a separate compartment, thus isolating the antenna from other circuit boards and reducing interference from the circuitry to the antenna.
