Description

Technical Field

[0001] This invention relates to the field of safety monitoring technology for large slopes and landslides caused by geological disasters, and in particular to a matrix-type landslide monitoring system and monitoring method. Background Technology

[0002] Traditional safety monitoring systems for slopes and landslides are all local and single-point measurements. They typically use crack gauges, accelerometers, and other instruments to measure the deformation, opening, and attitude parameters of individual local hazard points in order to determine whether there is a landslide risk.

[0003] Traditional methods for monitoring large landslides involve limited installation of measuring points, resulting in localized measurements that fail to cover the entire slope, especially when the slope area is large, and the monitoring equipment is also expensive. Therefore, a matrix-style, comprehensive monitoring system is needed. Summary of the Invention

[0004] Existing single-point monitoring methods cannot reflect the safety status of the entire slope in a timely and accurate manner. The purpose of this invention is to address the shortcomings of the existing technology by providing a matrix-type landslide monitoring system and method to achieve surface and matrix-type monitoring of the entire slope.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A matrix-type landslide monitoring system, characterized in that the surface of the landslide body being monitored is divided into M rows × N columns of sub-regions, the monitoring system comprising: There are M×N measurement units, each of which is set up in a corresponding sub-region and is used to monitor the landslide risk of the corresponding sub-region. A processor, comprising M output terminals and N input terminals; For each sub-region where a row is located, the processor has one and only one output terminal corresponding to it, and each output terminal of the processor is connected to one end of the measurement unit in the N sub-regions where the corresponding row is located. For each sub-region where a column is located, the processor has one and only one input terminal corresponding to it, and each output terminal of the processor is connected to the other end of the measurement unit in the M sub-regions where the corresponding column is located; The processor sequentially outputs level signals through M output terminals and simultaneously detects the input status of N input terminals. Based on the output terminal number corresponding to the output level signal and the input status of the N input terminals, it determines whether there is a landslide risk and the location of the risk point.

[0006] As a preferred embodiment, each measuring unit includes: Two insertion rods are installed vertically and vertically within the sub-area along the landslide direction; An alarm device, one end of which is connected to a plug rod via a rigid connector, and the other end of which is connected to another plug rod via another rigid connector; one signal line of the alarm device is used to connect to the output terminal of a processor, and the other signal line of the alarm device is used to connect to the input terminal of the processor.

[0007] As a preferred embodiment, the alarm is a switch-type alarm; when there is no landslide risk in the corresponding sub-area, the two signal lines of the alarm are open; when there is a landslide risk in the corresponding sub-area, the two signal lines of the alarm are connected.

[0008] As a preferred approach, when the tension of the rigid connector exceeds the preset tension, there is a risk of landslide in the corresponding sub-area.

[0009] As a preferred approach, M=N.

[0010] As a preferred embodiment, the rigid connector is a steel wire rope.

[0011] As a preferred embodiment, the processor includes a microcontroller.

[0012] In a preferred embodiment, the alarm includes a housing and two mounting portions for external connection. The housing contains a resilient element and a switch. One end of the switch is connected to one mounting portion via a rigid connector, which is segmented by the resilient element. The other end of the switch is connected to another mounting portion via another rigid connector. The switch is a contact switch or a limit switch.

[0013] Based on the same inventive concept, the present invention also provides a matrix landslide monitoring system and monitoring method, characterized in that the matrix landslide monitoring system is used to monitor landslide risks.

[0014] As a preferred embodiment, the processor cyclically outputs low-level signals through M output terminals, detects the input status of N input terminals, and determines whether there is a landslide risk and the location of the risk point based on the output terminal number corresponding to the low-level signal and the input status of the N input terminals. There is no risk of slippage when all N input terminals are in a high-level state. When the i-th output terminal outputs a low-level signal and the j-th input terminal is detected to be at a low level, it is determined that there is a landslide risk, and the risk point is located in the sub-region of the i-th row and j-th column.

[0015] Compared with existing technologies, this invention can solve the problem of insufficient coverage of traditional single-point measurement, realize surface and large-area monitoring of the entire slope, and at the same time, it is low in cost. Attached Figure Description

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments are clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a first aspect of the present invention provides a matrix-type landslide monitoring system, wherein the surface of the landslide body H to be monitored is divided into M rows × N columns of sub-regions, taking M=N=4 as an example, the monitoring system includes: 4×4 measurement units 1, each measurement unit 1 is set up one-to-one in each sub-region and is used to monitor the landslide risk of the corresponding sub-region; Processor 2, which includes 4 output terminals and 4 input terminals; For each sub-region where a row is located, processor 2 has one and only one output terminal corresponding to it, and each output terminal of processor 2 is connected to one end of measurement unit 1 in the four sub-regions where the corresponding row is located. For each sub-region where a column is located, processor 2 has one and only one input terminal corresponding to it, and each output terminal of processor 2 is connected to the other end of measurement unit 1 in the four sub-regions where the corresponding column is located. The processor 2 outputs level signals sequentially through four output terminals and simultaneously detects the input status of four input terminals. Based on the output terminal number corresponding to the output level signal and the input status of the four input terminals, it determines whether there is a landslide risk and the location of the risk point.

[0025] In field applications, the surface H of the landslide body being measured can be divided into equal parts or, according to the actual working conditions, into 4×4 sub-regions (e.g., Figure 2 As shown, there are 16 sub-regions in total (S1-S16), or 8×8 sub-regions, and other division methods.

[0026] One measurement unit 1 is installed in each sub-region, such as Figure 3 As shown, each measurement unit 1 includes: Two insertion rods 101 and 101' are installed in the sub-area along the landslide direction, one above the other. Insertion rods 101 and 101' are generally installed in the slope where there are cracks H01 or where there is a risk of landslide, and are used to fix the alarm 102. An alarm 102 is provided, one end of which is connected to a plug rod 101 via a rigid connector 103, and the other end of which is connected to another plug rod 101' via another rigid connector 103'. One signal line 104 of the alarm 102 is connected to the output terminal of a processor 2, and the other signal line 104' of the alarm 102 is connected to the input terminal of the processor 2. Preferably, the rigid connectors 103 and 103' are steel wire ropes. That is, the alarm 102 is fixed between the two plug rods 101 and 101' by steel wire ropes. When the crack H01 increases to a certain extent, the rigid connectors 103 and 103' pull the alarm 102 taut, thereby triggering the alarm signal.

[0027] Preferably, the alarm 102 is a switch-type alarm; when there is no landslide risk in the corresponding sub-area, the two signal lines 104 and 104' of the alarm 102 are open-circuited; when there is a landslide risk in the corresponding sub-area, the two signal lines 104 and 104' of the alarm 102 are connected. Preferably, when the tension of the rigid connecting parts 103 and 103' is greater than a preset tension, there is a landslide risk in the corresponding sub-area. The alarm 102 is installed on the landslide body H to be measured via the plug rods 101 and 101'. When a landslide occurs, the plug rods 101 and 101' will trigger the alarm 102, which functions like a push-button switch. Figure 1 As shown, the measurement is achieved by installing the equipment in a multi-row, multi-column matrix layout, covering the entire landslide body H.

[0028] The monitoring principle of alarm 102 is as follows: Under normal circumstances, the output of alarm 102 is a switch (the two signal lines 104 and 104' are not conductive). When a landslide occurs, the plug rods 101 and 101' are stretched, increasing the tension of the steel wire rope. At this time, alarm 102 is subjected to tension. When the tension exceeds the preset tension, the output of signal line 104' of alarm 102 is short-circuited, generating a trigger signal. Alarm 102 functions similarly to a button or switch.

[0029] Alarm 102 can also be replaced by a travel limit switch.

[0030] like Figure 4 As shown, the monitoring principle of a single sub-area utilizes the left and right linkage of the plugs 101, 101' and the alarm 102 to form a left and right linkage of a button.

[0031] The structure of the main sensing component alarm 102 of this invention is as follows: Figure 5 As shown, the alarm 102 includes a housing 1021 and two mounting portions 1022 and 1022' for external connection. The mounting portions 1022 and 1022' have mounting holes. The housing 1021 contains an elastic element 1023 and a switch 1024. One end of the switch 1024 is connected to one mounting portion 1022 via a rigid connector 103, which is segmented by the elastic element 1023. The other end of the switch 1024 is connected to another mounting portion 1022' via another rigid connector 103'. The switch 1024 is a contact switch or a limit switch. Under normal conditions, the signal lines 104 and 104' of the alarm 102 are open-circuited. When subjected to a force exceeding a certain value, the signal lines 104 and 104' are short-circuited, functioning similarly to a push-button switch.

[0032] In some preferred embodiments, the processor 2 includes a microcontroller.

[0033] like Figure 1 As shown, 4×4 or 8×8 measurement units 1 are arranged on the landslide body H in a 4-column × 4-row or 8-column × 8-row configuration, forming a structure as shown in the diagram. Figure 6 The equivalent circuit diagram is shown. Measurement unit 1 consists of a 4-row × 4-column matrix of buttons (S1-S16), and the subsequent acquisition device scans and acquires data through the processor 2 GPIO port.

[0034] Under normal circumstances, the output of alarm 102 is open (not conductive), which is considered as "the keypad is not pressed" from a circuit perspective; when a landslide occurs, the output of alarm 102 is short-circuited (conductive), which is considered as "the keypad is pressed" from a circuit perspective.

[0035] The matrix keyboard circuit utilizes the GPIO ports of a microcontroller for expansion design. It consists of row lines and column lines. The microcontroller J1 continuously sets the row lines to low level sequentially and then detects the input status of the column lines to determine whether the keyboard has output. Figure 6 As shown, P1, P2, P3, and P4 are column lines, and P5, P6, P7, and P8 are row lines. Column lines are input ports, and row lines are output ports. When a low level is output to the corresponding row line, if a button is pressed, the corresponding column line will be low. The microcontroller can read the state of that column to determine which button is pressed and locate the corresponding position.

[0036] In summary, this invention employs a method of installing multiple measuring units 1 in a surface or matrix distribution on the surface of the landslide being measured. Each measuring unit 1 operates independently, functioning similarly to a push-button switch. The multiple distribution methods, arranged in rows and columns, form a matrix-style push-button circuit, facilitating data acquisition by the subsequent data acquisition circuit processor 2. Row and column scanning is performed using a microcontroller's GPIO to identify the triggering of the alarm 102 within the measuring unit 1. By mapping this to the installation location, the landslide position can be quickly determined.

[0037] By varying the number of rows and columns of measurement points, an 8×8 matrix keyboard can be designed. This approach enables coverage of multiple measurement points over a wider area. Judgment can be achieved using a microcontroller's GPIO scanning, resulting in a low-cost monitoring solution.

[0038] Based on the same inventive concept, the present invention also provides a matrix landslide monitoring system and monitoring method, characterized in that the matrix landslide monitoring system is used to monitor landslide risks.

[0039] As a preferred embodiment, the processor 2 cyclically outputs low-level signals through M output terminals in sequence, detects the input status of N input terminals, and determines whether there is a landslide risk and the location of the risk point based on the output terminal number corresponding to the low-level signal and the input status of the N input terminals. There is no risk of slippage when all N input terminals are in a high-level state. When the i-th output terminal outputs a low-level signal and the j-th input terminal is detected to be at a low level, it is determined that there is a landslide risk, and the risk point is located in the sub-region of the i-th row and j-th column.
