Description

Technical Field

[0001] This utility model relates to the field of highway slope early warning technology, and in particular to an intelligent device for highway slope early warning. Background Technology

[0002] In modern highway maintenance, slope stability monitoring is one of the most crucial tasks. Slope instability leading to landslides, debris flows, and other disasters can cause immense damage to the lives and property of nearby residents, infrastructure, and the ecological environment. Furthermore, slope instability is usually not sudden but a gradual process. Changes in the soil and rock mass within the slope are often initially hidden, influenced by a combination of factors, many of which are inherently uncertain. Once slope instability occurs, it often triggers a series of chain reactions, thus posing a significant challenge to the effective monitoring of slope stability.

[0003] Currently, most highway maintenance units still rely on manual inspections for most slopes. For key slopes, monitoring may employ fixed-point monitoring, GNSS monitoring, sensor monitoring, and 3D laser scanning technology. (I) Manual observation of slope collapses, surface cracks, and settlement is highly subjective and can only observe surface changes, failing to detect internal deformation information. (II) Establishing fixed deformation observation points is limited by terrain and environment, making it difficult to guarantee the reliability and accuracy of observations in complex environments, and requiring significant manpower and time. (III) The cost of extensive sensor installation and GNSS monitoring is high, requiring regular maintenance and calibration, and carries the risk of accidental activation; different sensors may also present system compatibility issues. (IV) 3D laser scanning acquires 3D point cloud data of the slope surface, but this method involves massive data processing, expensive equipment, and poor environmental adaptability. To address these issues, a low-cost intelligent device for highway slope early warning is proposed, capable of monitoring slopes and providing timely signal warnings. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, the present invention provides an intelligent device for early warning of highway slopes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An intelligent device for highway slope early warning includes a data acquisition module, an integrable communication module, a power supply module, and an inspection platform. The data acquisition module monitors the slope condition; the integrable communication module transmits the slope condition information acquired by the data acquisition module to the inspection platform; and the inspection platform outputs early warning signals.

[0007] The acquisition module includes a column with a pull-wire sensor and a column without a pull-wire sensor. The column with the pull-wire sensor has a pull-wire sensor located near the top, and the column without a pull-wire sensor has a tension strain gauge inside.

[0008] Preferably, the end of the pull-wire sensor is connected to a reference object via a thin steel wire, and the column with the pull-wire sensor is connected to the column without the pull-wire sensor located behind it via a thin steel wire.

[0009] Preferably, the other side wall of the non-wire sensor column is provided with a semi-circular connector, and the tension strain gauge is connected to the side wall of the wire sensor column or the semi-circular connector located in front of it via a thin steel wire.

[0010] Preferably, a second signal warning light is provided on the top of the pull-wire-free sensor column.

[0011] Preferably, both the pull wire sensor and the tensile strain gauge are electrically connected to an integrable communication module via a transmission line.

[0012] Preferably, the wire-guided sensor columns and wireless sensor columns are vertically inserted into the slope soil in a straight line or matrix arrangement.

[0013] Preferably, the power module can supply power to the acquisition module and the integrable communication module, and the power module uses a photovoltaic solar panel to provide power.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When a landslide occurs on a slope, the warning light on the corresponding wireless sensor column at the landslide location illuminates. Simultaneously, an integrated communication module transmits the received landslide warning signal to the inspection platform. Highway maintenance departments can then quickly take countermeasures based on the warning information to prevent the accident or mitigate its damage. This invention can significantly reduce the manpower requirements and equipment costs for landslide monitoring on highways and other slopes, meet the landslide early warning requirements of highway maintenance departments, and improve slope safety monitoring capabilities.

[0016] 2. The power module uses photovoltaic solar panels to provide power, which makes it easy to deploy in locations such as slopes where it is difficult to connect to electricity, and provides a certain degree of deployment flexibility.

[0017] In summary, this utility model overcomes the shortcomings of the prior art by vertically inserting poles with and without wired sensors into the slope soil in a straight line or matrix arrangement to monitor the slope and provide timely signal warnings. This reduces monitoring costs, improves monitoring capabilities, and has high social value and application prospects. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Reference Figure 1-3 An intelligent device for early warning of highway slopes includes a data acquisition module, an integrable communication module, a power supply module, and an inspection platform. The data acquisition module monitors the slope condition. When a landslide occurs, the data acquisition module receives a landslide warning signal and transmits it to the integrable communication module. At the same time, the integrable communication module sends the received landslide warning signal to the inspection platform. Highway maintenance departments can then quickly take countermeasures based on the warning information to prevent accidents or mitigate the damage caused by accidents.

[0025] The data acquisition module includes a column 11 with a guy wire sensor and a column 12 without a guy wire sensor. The column 11 with a guy wire sensor and the column 12 without a guy wire sensor are arranged vertically in a straight line or a matrix and inserted vertically into the slope soil.

[0026] Furthermore, the pull-wire sensor column 11 is located at the front and connected to the fixed reference object, while the others are pull-wire sensor columns 12.

[0027] A pull-wire sensor 111 is provided on the side wall of the column 11 with pull-wire sensor near the top. The end of the pull-wire sensor 111 is connected to a reference object through a thin steel wire 13. The column 11 with pull-wire sensor is connected to the column 12 without pull-wire sensor located behind it through the thin steel wire 13. One end of the thin steel wire 13 near the pull-wire sensor column 11 is sleeved on the side wall of the pull-wire sensor column 11 near the top. The pull-wire sensor 111 is electrically connected to an integrable communication module through a transmission line 14.

[0028] The tension strain gauge 121 is installed inside the pull-wireless sensor column 12. A second signal warning light 122 is installed on the top of the pull-wireless sensor column 12. A semi-circular connector 123 is installed on the other side wall of the pull-wireless sensor column 12. The tension strain gauge 121 is connected to the side wall of the pull-wire sensor column 11 or the semi-circular connector 123 located in front of it through a thin steel wire 13. The semi-circular connector 123 on the pull-wireless sensor column 12 is connected to the tension strain gauge 121 behind it. The tension strain gauge 121 is electrically connected to the integrable communication module through a transmission line 14.

[0029] Furthermore, the connection between the steel wires 13 is a loose connection, which reduces the possibility of accidental activation. When an accidental activation occurs, it will only cause a short alarm before returning to normal. In the event of a landslide, the alarm will be triggered for a long time, thus determining whether it is an accidental activation.

[0030] When a landslide occurs on the slope at column 11 with a guy wire sensor, the guy wire sensor 111 can clearly measure the specific displacement value at this location. At the same time, the warning location information is transmitted to the integrable communication module via transmission line 14, and the signal is sent to the inspection platform for warning. When a landslide occurs on the slope at column 12 without a guy wire sensor, the strain gauge 121 of column 12 without a guy wire sensor will undergo a slight deformation due to the tension of the steel wire 13, which will activate the internal switch. The second signal warning light 122 at this location will light up, and the warning location information will be transmitted to the integrable communication module via transmission line 14, and the signal is sent to the inspection platform for warning.

[0031] Furthermore, the power module can supply power to the acquisition module and the integrable communication module. The power module uses photovoltaic solar panels to provide power, which makes it easy to deploy in locations such as slopes where it is difficult to connect to electricity, and has a certain degree of deployment flexibility.

[0032] Working principle: Columns 11 with guy wire sensors and columns 12 without guy wire sensors are vertically inserted into the slope soil in a straight line or matrix arrangement. When a landslide occurs at the location of column 11 with guy wire sensors, the guy wire sensor 111 can accurately measure the displacement value and transmit the warning location information via transmission line 14 to an integrable communication module. The integrable communication module then sends the signal to the inspection platform for warning. When a landslide occurs at the location of column 12 without guy wire sensors, the strain gauge 121 of column 12 without guy wire sensors is subjected to tension from the thin steel wire 13. When tension causes a slight deformation, the internal switch is activated, and the second warning light 122 at that location illuminates. Simultaneously, the warning location information is transmitted via transmission line 14 to the integrable communication module, which then sends the signal to the inspection platform for warning. Highway maintenance departments can then quickly take countermeasures based on the warning information to prevent accidents or mitigate their harm. This invention can greatly alleviate the manpower requirements and equipment costs for landslide monitoring on highways and other slopes, meet the requirements of highway maintenance departments for landslide early warning, and improve slope safety monitoring capabilities.
