Description

[0001] This application claims the priority right of patent application No. 2023229651043 (the filing date of the prior application is November 02, 2023, and the name of the invention is: Mountain geological disaster safety monitoring and early warning equipment applied to unmanned vehicles). Technical Field

[0002] The present application relates to the field of unmanned driving technology, and in particular to a mountain geological disaster safety monitoring and early warning device applied to an unmanned vehicle. Background Art

[0003] The existing mountain geological disaster monitoring scheme usually involves setting up fixed observation equipment on the mountain to detect geological changes. The existing technologies also include manual inspection, remote sensing monitoring and geological early warning, which have the following problems:

[0004] Poor real-time performance, unable to automatically detect and avoid some obvious mountain geological disasters in advance and cause operational risks to unmanned vehicles;

[0005] High cost, requiring installation of a large amount of fixed equipment, with extremely high installation and maintenance costs;

[0006] Easy to fail. When a geological disaster occurs, common fixed observation facilities may be damaged by the geological disaster and fail.

[0007] Manual inspections require high manpower and material costs, and it is difficult to achieve all-weather monitoring; although remote sensing monitoring can achieve all-weather monitoring, the monitoring accuracy for small-scale geological disasters is low; although earthquake early warning can warn of earthquakes in advance, it is less effective for other types of geological disasters. In addition, existing technologies still have problems such as poor real-time performance, high cost, and easy failure, which makes it difficult to meet the needs of unmanned vehicles for real-time, accurate, and reliable geological disaster monitoring.

[0008] With the widespread use of driverless vehicles, people have begun to explore the use of driverless technology in mountainous areas with certain geological disaster risks. However, the main driverless technology detection devices on the market are basically only for general urban roads, and there is no targeted solution for abnormal situations that are prone to occur in mountainous areas due to mountain geological disasters (such as rockfalls, landslides, etc.).

[0009] Mountain geological disasters refer to the destruction and deformation of mountains in mountainous areas due to the influence of geological structure, groundwater, meteorology and other factors, which lead to disasters such as landslides, collapses, and mud-rock flows. These disasters not only threaten people's lives and property safety, but also bring huge challenges to transportation. Therefore, the research and development of unmanned driving technology for mountain geological disasters is imperative.

[0010] First of all, unmanned driving technology for mountain geological disasters needs to have strong perception capabilities. Current unmanned driving technology mainly relies on sensors such as lidar, cameras and radar to perceive the surrounding environment, but there are some problems with the application of these sensors in mountainous areas. The sensor solutions usually involved only focus on the road and the vehicle's surrounding conditions. And can accurately detect abnormal conditions such as rockfall and landslides. In mountainous areas, geological disasters are often sudden and unpredictable, so unmanned vehicles need to have the ability to respond quickly and make intelligent decisions. For example, when an unmanned vehicle senses a landslide in the mountain, it needs to be able to quickly judge and take corresponding avoidance measures to ensure the safety of the vehicle and passengers. Therefore, it cannot rely on remote control personnel or passengers to make decisions.

[0011] In addition, unmanned driving technology for mountain geological disasters also needs to have strong communication capabilities. In mountainous areas, due to the complex terrain, the transmission of communication signals is difficult. Therefore, unmanned vehicles need to be able to maintain a stable communication connection with the outside world through satellite communications or other means, so as to receive information about geological disasters in a timely manner, and be able to transmit the vehicle's status and location information to relevant departments for disaster response and rescue work.

[0040] In order to solve the problems existing in geological disaster monitoring in the existing technology, we designed a mountain geological disaster safety monitoring and early warning device for use in unmanned vehicles.

[0041] like Figure 1 As shown, the safety monitoring and early warning device 100 includes a sensor module 10 and a pitch adjustment member 20. The pitch adjustment member 20 is used to adjust the pitch angle of the sensor module 10.

[0042] refer to Figure 1 and Figure 5 The sensor module 10 includes a sensor kit 30 and a bracket 40. The sensor kit 30 includes two sensors, a laser radar and a camera. As an example, the laser radar is a solid-state laser radar and is located above the camera. In some embodiments, the camera can be located above the laser radar. The bracket 40 is used to support the sensor kit 30. Furthermore, a rainproof structure 41 is also provided on the bracket 40 above the sensor kit 30. In some embodiments, the rainproof structure 41 is arbitrary, such as an extension structure on the bracket 40 located above the sensor kit 30, or a telescopic structure above the bracket 40, which can be extended to block raindrops when it rains. In some embodiments, the sensor kit 30 includes only one of a laser radar and a camera.

[0043] like Figure 3 , which is a schematic diagram of the pitch adjustment member 20. The pitch adjustment member 20 includes two vertical plates 21 placed opposite to each other, at least one connecting plate 22 vertically connected to the two vertical plates 21, a sliding component 23 and an axis component 24. The sliding component 23 slides relative to the vertical plates 21 with the axis component as the center of the circle to achieve pitch angle adjustment of the sensor kit 30.

[0044] In some embodiments, at least one of the two vertical plates 21 is a fan-shaped plate, and the sensor kit 30 and the bracket 40 are defined between the two vertical plates 21 .

[0045] In some embodiments, the connecting plate 22 is not necessary, and two vertical plates 21 placed opposite each other can be welded to the unmanned vehicle to achieve the effect of confining the sensor kit 30 and the bracket 40 between the two vertical plates 21 and adjusting the pitch angle of the sensor kit 30.

[0046] At least one of the two vertical plates 21 is provided with an arc track 25. The arc track 25 can be provided at the inner edge of at least one vertical plate 21, that is, provided at the inner side of at least one vertical plate 21, for example, it can be a groove structure that does not penetrate the plate opened on the vertical plate 21, or a slot-like structure that penetrates the plate opened on the vertical plate 21. In some embodiments, the arc track 25 can be provided at the outer edge of at least one vertical plate 21, for example, as mentioned above, at least one vertical plate 21 is provided in a fan shape, in which case the edge of the fan-shaped plate is arc-shaped, and as the arc track 25, the sliding component 23 can slide on the outer edge of the fan-shaped plate.

[0047] The axis component 24 is located on the vertical plate 21, and the sliding component 23 is connected to the sensor module 10 and slides on the arc track 25, so that the sensor kit 30 rotates around the axis component 24 in an arc track to adjust the pitch angle. The number and position of the sliding components 23 correspond to the arc track 25.

[0048] In some embodiments, at least one connecting plate 22 is located below the sensor module 10. The pitch adjustment member 20 has a component that functions to limit the sensor module 10. When the pitch angle is too high, the limiting component is an arc track; when the pitch angle is too low, the component that functions to limit the sensor module 10 may be the connecting plate 22 or the arc track 25.

[0049] In some embodiments, at least one connecting plate 22 is located above the sensor module 10. The pitch adjustment member 20 has a component that functions to limit the sensor module 10. When the pitch angle is too low, the limiting component is an arc track 25; when the pitch angle is too high, the component that functions to limit the sensor module 10 may be the connecting plate 22 or the arc track 25.

[0050] As before, the arc track 25 can be set on the outer edge of at least one vertical plate 21, and the sliding component 23 can slide on the outer edge of the fan-shaped plate. Two connecting plates 22 perpendicular to the vertical plate 21 can be set as the upper and lower limit limit components of the pitch angle respectively; protrusions can also be set at both ends of the outer edge of the fan-shaped plate as the upper and lower limit limit components of the pitch angle; a protrusion can also be set at one end of the outer edge of the fan-shaped plate as a limit component of the pitch angle, and the other end can be set by setting the connecting plate 22 as a limit component to achieve the limit function.

[0051] refer to Figures 1 to 4 When the unmanned vehicle is driving on a mountain road, the pitch angle of the sensor kit 30 can be adjusted to monitor mountains of different heights, thereby monitoring natural disasters such as landslides. The unmanned vehicle can avoid danger and send messages to relevant departments to deal with natural disasters such as landslides.

[0052] The unmanned vehicle is equipped with an on-board controller (or intelligent driving domain controller). In some embodiments, the safety monitoring and early warning device 100 also includes a driving mechanism, and the driving mechanism and the sensor kit 30 communicate with the on-board controller. Specifically, when the unmanned vehicle is driving on a mountain road, the sensor kit 30 collects the sensor data of the mountain (such as images, laser radar point clouds, or at least one of other sensor data) and sends it to the on-board controller; the on-board controller analyzes the sensor data, and determines whether the pitch angle of the current sensor kit 30 needs to be adjusted and the amount of adjustment based on the sensor data. If it is determined that the pitch angle of the current sensor kit 30 needs to be adjusted, the amount to be adjusted is converted into a control signal of the driving mechanism and sent to the driving mechanism; the driving mechanism adjusts the pitch angle of the sensor kit based on the received control signal. In some cases, the driving mechanism is always working. For example, when the current mountain is high, the pitch angle is always adjusted to achieve the effect of scanning the entire mountain. When a landslide or mudslide is scanned at a certain position of the mountain, the unmanned vehicle can send the geological disaster monitoring results to the control center.

[0053] The means of implementing the driving mechanism can be arbitrary. In some embodiments, the driving mechanism includes a motor, a driving gear and a driven gear. The motor controls the driving gear to rotate. The driven gear is sleeved on the shaft component 24 and meshes with the driving gear. When the driving gear rotates, it is driven, thereby driving the shaft component 24 to rotate, thereby achieving the pitch angle adjustment of the sensor kit 30. In some embodiments, the driving mechanism includes a motor, a fixed pulley and a connecting rope. One end of the connecting rope is connected to the motor, and the other end is connected to the sliding component 23. The motor controls the connecting rope to bypass the fixed pulley to extend and retract, and then the sliding component 23 connected to the connecting rope slides along the arc track 25.

[0054] It is worth noting that the data communication between the above-mentioned drive mechanism and the on-board controller, between the on-board controller and the sensor, and the data processing inside the on-board sensor can be carried out in the existing manner and are not the content to be protected by this application. The content to be protected by this application is a mountain geological disaster safety monitoring and early warning device applied to an unmanned vehicle.

[0055] The present application discloses a mountain geological disaster safety monitoring and early warning device applied to an unmanned vehicle, which does not need to deploy a large number of fixed equipment in multiple locations in the mountains, thus saving costs; at the same time, the device can be installed on one vehicle for patrolling in the mountains.

[0056] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
