[0027] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] In some examples, common landslide early warning monitoring systems mainly use a variety of sensor devices to collect a variety of key data including displacement, inclination, soil pressure, rainfall, and groundwater level to sense the movement of the mountain and identify potential landslide risks. These landslide early warning monitoring systems are mostly composed of monitoring stations and cloud monitoring platforms. The monitoring stations upload sensor data and analyze and process it in the cloud to predict and judge possible landslide disasters. However, this type of system has a strong dependence on the network environment, a small monitoring range of a single device, and high equipment networking deployment costs.

[0029] In some examples, the landslide early warning monitoring system also collects the vibration frequency, inclination offset increment, inclination offset mode and displacement increment parameters of the target landslide through sensors deployed at monitoring grid points, calculates the comprehensive danger level of the landslide, constructs a landslide digital parameter and early warning parameter model, and displays the landslide status and monitoring and early warning results. This method has the advantages of being systematic, accurate and real-time, but it also has the problems of complex calculation and processing and high cost of on-site equipment deployment.

[0030] In some examples, the landslide early warning monitoring method includes: collecting laser point cloud data of the area to be monitored, and further extracting three-wheel contour structures in the three dimensions of XY, XZ, and YZ according to the reflection intensity, to obtain the landslide deformation intensity and realize landslide deformation early warning. This method has the advantage of high accuracy in deformation data collection, but it also has the problems of difficult on-site equipment deployment, high calculation complexity, and high monitoring cost.

[0031] Based on this, the present application proposes a landslide monitoring method, which deploys an industrial Internet of Things host and a signal generating terminal device in the landslide area to be monitored, and calculates the distance and distance change between each terminal device and between the terminal device and the Internet of Things host device through the time difference between the signal transmission and the signal reception, so as to obtain the surface displacement of each terminal device arrangement point in the area to be monitored through further analysis and calculation, thereby realizing the prediction and judgment of disasters in the landslide area and effectively protecting the personal and property safety of residents around the landslide. In addition, the signal generating terminal device of the present application does not need to be configured with a sensor, which significantly reduces the hardware cost and power consumption of the equipment.

[0032] Figure 1It is a flow chart of a landslide monitoring method according to an embodiment of the present application.

[0033] As an example, Figure 1 As shown, landslide monitoring methods include:

[0034] S101, receiving radio signals from multiple terminal devices.

[0035] S102, determining device distance information based on the radio signal, wherein the device distance information includes at least one of distance information between terminal devices and distance information between the host device and the terminal device.

[0036] S103, determining a change trend of the landslide area to be monitored based on the equipment distance information, and performing landslide monitoring based on the change trend.

[0037] Exemplarily, the above-mentioned landslide monitoring method is applied to a host device, which can be an industrial Internet of Things host. The host device can be deployed at a preset position, for example, at a fixed position on the top of the slope where no displacement will occur. Of course, it can also be deployed at other positions. To save costs, the host device can be powered by a solar panel installed on the top, or other power supply methods can be used. The host device communicates with a multi-level terminal device, and the multi-level terminal device is deployed in the landslide area to be monitored. It can be understood that the multi-level terminal device is equivalent to multiple monitoring points, which can be evenly deployed in the landslide area to be monitored, or can be deployed in the landslide area to be detected in a preset manner. The terminal device can be understood as a signal generating device, and the power supply method of the terminal device can be a battery power supply method. This application uses battery power supply instead of the common solar panel power supply method, which reduces the hardware cost of the terminal device. The multi-level terminal device is configured to send radio signals to adjacent terminal devices of the same level and / or the previous level, and receive radio signals from adjacent terminal devices of the same level and / or the next level. For the convenience of explanation, the terminal device that directly communicates with the host device is referred to as the first-level terminal device, the terminal device that directly communicates with the first-level terminal device is referred to as the second-level terminal device, and so on.

[0038] Exemplarily, the host device receives radio signals from multiple levels of terminal devices through step-by-step forwarding between multiple levels of terminal devices. The radio signal includes information such as time, and the host device determines the device distance information by solving the radio signal, for example, the device distance information is obtained through the transmission time of the radio signal and the transmission speed of the radio signal. The device distance information includes at least one of the distance information between the terminal devices and the distance information between the host device and the terminal device. The change trend of the landslide area to be monitored is determined based on the device distance signal, for example, the change trend of the landslide area to be monitored is determined based on the change amount of the real-time device distance information, and the landslide monitoring is performed based on the change trend.

[0039] The landslide monitoring method of the present application is based on a calculation method of signal transmission time using multiple terminal devices to obtain the surface displacement distribution of the landslide to be detected and the landslide warning status. This landslide displacement monitoring method based on signal transmission time is simple to calculate, suitable for a variety of occasions, reduces the calculation load of hardware equipment, and provides a low-cost landslide area monitoring solution.

[0040] As an example, Figure 2 As shown, the host device includes a navigation module, and the host device communicates with the multi-level terminal devices through a wireless communication module. The landslide monitoring method also includes:

[0041] S201, receiving a time signal based on a navigation module.

[0042] S202, sending a time signal to a terminal device based on a wireless communication module, so that the terminal device forwards the time signal level by level according to the level of the terminal device, so as to achieve time synchronization between the host device and multi-level terminal devices.

[0043] For example, the landslide monitoring method based on independent ad hoc network cluster of the present application first needs to realize time synchronization between each terminal device and the host device. Among them, a navigation module can be installed in the host device, such as a GPS / Beidou module. The host device receives the time signal through the navigation module, and sends the time information layer by layer to the signal transmitting terminal in the ad hoc network system through the wireless communication module, so as to realize the time synchronization between each device in the ad hoc network system.

[0044] The present application adopts an internal signal transmission method between multiple terminal devices and the host in the self-organizing network cluster, which significantly reduces the signal communication cost.

[0045] As an example, the radio signal includes sending terminal device information, receiving terminal device information, sending time information, and receiving time information. Determining device distance information between terminal devices based on the radio signal includes: determining the distance information between the sending terminal device and the receiving terminal device based on the sending time information and the receiving time information.

[0046] Exemplarily, the terminal device sends a radio signal with the device information and signal transmission time information to the terminal device of the previous level and the adjacent terminal device of the same level, receives the radio signal with the sending terminal device information, the receiving terminal device information and the signal sending and receiving time from the next level or adjacent signal generating device, and forwards it to the host device step by step. The host device performs distance calculation based on the information in the radio signal. The sending terminal device information and the receiving terminal device information can be device ID information. With respect to the distance information between the terminal devices, the host device determines the distance information between the sending terminal device and the receiving terminal device based on the sending time information and the receiving time information.

[0047] For example, a signal generating device in the ad hoc network system sends out a radio signal with the local ID information and the signal transmission time, which is received by the adjacent and upper-level terminal devices or host devices. At this time, the distance between the signal transmitting and receiving ends can be calculated according to the time interval between the signal transmission and reception, as shown in the following formula:

[0048] l m,n (t) = c·Δτ m,n (t)

[0049] Among them, l m,n (t) is the distance between terminal device m and terminal device n at the tth time point, c is the transmission speed of the radio signal in the air, Δτ m,n (t) is the time difference between the signal transmitted by terminal device m and the signal received by terminal device n at the tth time point.

[0050] As an example, the radio signal includes sending terminal device information and sending time information, and determining the device distance information between the host device and the terminal device based on the radio signal includes: determining the distance information between the host device and the sending terminal device based on the sending time information and the local receiving time information of the host device.

[0051] Exemplarily, the upper level of the first-level terminal device is the host device. The host device receives a radio signal from the first-level terminal device. The radio signal includes sending terminal device information and sending time information. The sending terminal device information may be sending terminal ID information. The host device calculates the distance information between the host device and the sending terminal device based on the time difference between the sending time information of the radio signal and the local receiving time information of the host device.

[0052] For example, the above formula 1 m,n (t) = c·Δτ m,n (t) can also be used to calculate the distance information between the host device and the terminal device.

[0053] As an example, the terminal device is configured to send a radio signal to an adjacent terminal device at the same level and / or the previous level, and receive a radio signal from an adjacent terminal device at the same level and / or the next level, wherein the terminal device includes a first terminal device and a second terminal device at the same level and adjacent to each other. Figure 3 As shown, determining device distance information between terminal devices based on radio signals includes:

[0054] S301, determining a first distance between a first terminal device and a second terminal device based on a radio signal from a first terminal device, and determining a second distance between a second terminal device and the first terminal device based on a radio signal from a second terminal device.

[0055] S302: Determine distance information between the first terminal device and the second terminal device based on the first distance and the second distance, wherein the distance information is obtained according to expectations of the first distance and the second distance.

[0056] Exemplarily, for adjacent terminal devices of the same level, the two terminal devices send radio signals containing sending terminal device information and sending time information to each other. For distance calculation between adjacent terminal devices of the same level, one of the radio signals sent by the two terminal devices can be used for distance calculation, or the two radio signals can be combined for distance calculation.

[0057] Exemplarily, the adjacent terminal devices of the same level are respectively the first terminal device and the second terminal device. The first distance between the first terminal device and the second terminal device is determined according to the radio signal from the first terminal device, and then the second distance between the second terminal device and the first terminal device is determined according to the radio signal from the second terminal device. The distance calculation method is similar to the above method and will not be repeated here. The final distance information between the first terminal device and the second terminal device is obtained according to the expectations of the first distance and the second distance.

[0058] For adjacent terminal devices of the same level, the present application can take the expectation of two distance calculations as the distance between the two terminal devices. This distance calculation method has higher accuracy.

[0059] As an example, based on the above distance calculation method, the distance between adjacent devices in the ad hoc cluster system can be expressed as:

[0060]

[0061] Among them, [l0(t),l1(t),…,l m (t)] is the distance between the first-layer signal generating device of the system and the fixed installation host; It is the horizontal distance between adjacent terminal devices on the first layer of the system; is the vertical distance between adjacent terminal devices on the first and second layers of the system; m and n are the number of columns and rows of the terminal device array of the ad hoc network system, respectively.

[0062] Figure 4 It is an overall framework diagram of an independent self-organizing network cluster landslide detection system according to an embodiment of the present application.

[0063] like Figure 4As shown, an industrial IoT host device can be deployed on the top of a slope or other fixed locations that will not move. The host device is powered by a solar panel installed on the top. The main control board of the host device is equipped with a GPS / Beidou module, which receives the current time / location information and forwards it to the first-level signal generating terminal device to complete time synchronization. The main control board of the host device is also connected to the radio communication module to receive the radio signal with time and device ID information sent by the first-level signal generating device.

[0064] like Figure 4 As shown in the figure, the first-level signal generating terminal equipment can be evenly deployed in the landslide area to be monitored, powered by a built-in battery, and sends the device ID and signal sending time to the industrial Internet of Things host and adjacent signal generating equipment installed on the top of the slope, and receives the radio signal with the sending device ID, the device ID and the signal sending and receiving time from the next level or adjacent signal generating device, and the completion time is the same as that of the next level signal generating terminal equipment. Each level of signal generating terminal equipment sends signals to the upper level and adjacent terminal equipment during actual operation, receives the signal and time information sent by the next level and adjacent terminal equipment, and finally realizes that all terminal signal generating device IDs and signal sending / receiving information in the self-organizing network system are sent to the industrial Internet of Things host fixedly installed on the top of the slope. The host equipment calculates the distance and distance change between each terminal signal generating device and between the signal generating device and the host, and further analyzes and calculates the position change of each signal generating device in the landslide area to be monitored, that is, the surface deformation condition of the landslide area, and stores it in the host storage module. According to the actual on-site signal condition, it is determined whether to upload it to the cloud, so as to realize the landslide status monitoring and early warning of the landslide area to be monitored.

[0065] As an example, the same-level terminal devices are arranged according to a first direction, and the different-level terminal devices are arranged according to a second direction. The change trend of the landslide area to be monitored includes at least one of the change trend of the landslide area to be monitored in the first direction and the change trend of the landslide area to be monitored in the second direction. The change trend of the landslide area to be monitored is determined based on the device distance information, including:

[0066] Based on the distance information between terminal devices of the same level, the change trend of the landslide area to be monitored in the first direction is determined; and / or based on the distance information between terminal devices of different levels, the change trend of the landslide area to be monitored in the second direction is determined.

[0067] Exemplarily, terminal devices of the same level can be arranged according to a first direction, which can be a horizontal direction, and terminal devices of different levels can be arranged according to a second direction, which can be a vertical direction. A fixedly deployed industrial Internet of Things host device can be set as the origin of the coordinate system to establish a world coordinate system Oxy, wherein the movement direction of the terminal device in the horizontal direction of the slope can be regarded as a change on the x-axis, and the movement direction in the vertical direction of the slope can be regarded as a change on the y-axis. Therefore, the change trend of the landslide area to be monitored includes at least one of the change trend of the landslide area to be monitored in the first direction and the change trend of the landslide area to be monitored in the second direction, that is, the change trend of the landslide area to be monitored includes the change trend in the horizontal direction and the change trend in the vertical direction.

[0068] Exemplarily, for the distance information between terminal devices of the same level, the terminal devices of the same level are adjacent in the first direction, and the change trend of the landslide area to be monitored in the first direction can be determined based on the distance information of the terminal devices of the same level in the first direction. Similarly, terminal devices of different levels are adjacent in the second direction, and the change trend of the landslide area to be monitored in the second direction can be determined based on the distance information of the terminal devices of different levels in the second direction. For example, for two terminal devices adjacent in the horizontal direction, the change of their distance based on the signal transmission time difference directly reflects the change of the coordinate difference of the two devices in the x-axis direction, while for two terminal devices adjacent in the vertical direction, the change of their distance based on the signal transmission time difference directly reflects the change of the coordinate difference of the two devices in the y-axis direction.

[0069] As an example, the host device is in a preset position, such as Figure 5 As shown, the change trend of the landslide area to be monitored is determined based on the equipment distance information, including:

[0070] S501, based on the distance information between the host device and the terminal device, taking the position of the host device as the origin, determining first displacement information of the terminal device in a first direction and second displacement information of the terminal device in a second direction.

[0071] S502: Determine a change trend of the landslide area to be monitored based on the first displacement information and the second displacement information.

[0072] Exemplarily, the host device can be set at a preset position, for example, the top of a slope. The position of the industrial Internet of Things host arranged at a fixed position on the top of the slope is fixed, and a coordinate system is established with the position of the host device as the origin. The first direction can be a horizontal direction, and the second direction can be a vertical direction. Determine the first displacement information of each terminal device in the first direction and the second displacement information of each terminal device in the coordinate system. For example, determine each terminal device on each layer in the self-organizing network system, take the host coordinate position as the origin, and calculate its coordinate changes on the x-axis and y-axis. Determine the change trend of the entire landslide area to be monitored based on the first displacement information and the second displacement information of each terminal device.

[0073] For example, taking the host coordinate position as the origin, the coordinate change of each terminal device is shown in the following formula:

[0074]

[0075] in, It is the signal generating device in the i-th row and j-th column in the terminal device array of the self-organizing network system. At this time, a landslide area monitoring model can be constructed according to the displacement change values ​​and change trends of each monitoring point in the landslide area to realize the monitoring and early warning of the landslide area to be monitored.

[0076] As an example, the host device includes an internal storage module, and the landslide detection method further includes: when the network quality is lower than a preset quality, storing the distance information in the internal storage module.

[0077] Exemplarily, the host device monitors the position change of each signal generating device in the landslide area to be monitored, that is, the deformation condition of the surface of the landslide area, and stores it in the host storage module, and determines whether to upload it to the cloud based on the actual on-site signal condition. For example, when the network condition is poor, the displacement data of all landslide monitoring points in the system are directly stored in the internal storage module, which has stronger environmental adaptability. When the network condition is good, the deformation condition of the surface of the landslide area is uploaded to the cloud.

[0078] Figure 6 It is a flow chart of a landslide monitoring and early warning method based on an independent ad hoc network cluster according to an embodiment of the present application.

[0079] like Figure 6 As shown in the figure, the host device in the system receives the time signal through the GPS / Beidou module and completes the time synchronization with the signal generating terminal device. The signal generating terminal transmits a radio signal with the local ID and signal transmission time to the upper-level terminal device and the adjacent terminal device. The terminal device receives the signal and time information sent by the lower-level and adjacent terminal devices, and transmits the signal according to the signal transmission time Δτ. m,n (t) Calculate the distance l between adjacent devices m,n(t). Based on the above distance calculation method, the displacement of the landslide surface at each terminal device layout point is calculated. According to the displacement changes of each terminal device layout point, a landslide area monitoring model is constructed to realize landslide monitoring and early warning.

[0080] The landslide monitoring method of the present application is based on a self-organizing network cluster, and uses a calculation method of the signal transmission time of multiple terminal equipment time to obtain the landslide surface displacement distribution and landslide warning status, providing a low-cost landslide area monitoring solution. In addition, the terminal equipment used in the system does not need to be equipped with high-precision sensors to detect parameters such as displacement, inclination, soil pressure, rainfall, groundwater level, etc., which significantly reduces the equipment hardware cost and power consumption. The present application uses battery power supply instead of the common solar panel power supply method, further reducing the equipment hardware cost. At the same time, the internal signal transmission method is adopted between the multiple terminal devices in the self-organizing network cluster system and the host, which reduces the signal communication cost, and the host side can directly store the displacement data of all landslide monitoring points in the system directly in the internal storage module when the network condition is poor, which has stronger environmental adaptability. The landslide displacement monitoring method based on signal transmission time of the present application is simple to calculate, which reduces the calculation load of the hardware equipment.

[0081] This application also proposes a landslide monitoring method.

[0082] As an example, the landslide monitoring method is applied to a terminal device, the terminal device communicates with a host device, the terminal device includes a multi-level terminal device, and the multi-level terminal device is deployed in a landslide area to be monitored. The landslide monitoring method includes:
