Embodiment 1

[0061] figure 1 It is a block diagram of the system described in the embodiment of the present invention, which may specifically include the following subsystems:

[0062] Multi-parameter intelligent monitoring subsystem, used for system control and analysis of multi-parameter data;

[0063] The multi-parameter sensing monitoring subsystem is used to detect the atmospheric rainfall and the accumulation of rainfall, the water content of the soil or sliding surface, and the change of surface cracks caused by landslides;

[0064] The data transmission subsystem mainly transmits the effective monitoring data in the field to the monitoring center through the wireless network;

[0065] The power supply subsystem is used to provide power support for the whole system.

[0066] The analysis process of each subsystem is described in detail below.

[0067] (1) Multi-parameter intelligent monitoring subsystem

[0068] This subsystem is used for multi-parameter intelligent monitoring, ...

Embodiment 2

[0078] This embodiment describes in detail the monitoring method using the system described in Embodiment 1.

[0079] In the first step, the multi-parameter sensor subsystem collects the data of the atmospheric rainfall monitoring terminal and the soil moisture monitoring terminal every 1s, and transmits the collected data to the micro-control module through the multi-channel IO port. Complete the accumulative calculation of atmospheric rainfall or soil water content in a short period of time (the present embodiment takes minutes as a unit and takes a value of 1min) and longer time (this embodiment takes an hour as a unit and takes a value of 1h) in the micro-control module. This step only provides a switching amount of electricity, so it will not cause a large loss of electricity and truly achieve real-time monitoring. The measured data will be stored in the memory through the controller instead of being directly sent to the monitoring center by using the wireless transmissio...

Embodiment 3

[0085] This embodiment gives the specific installation method of the monitoring system when performing intelligent monitoring, such as figure 2 , the multi-parameter intelligent monitoring and control subsystem, the wireless transmission module of the data transmission subsystem, the spare rechargeable dry battery of the power supply subsystem, the intelligent charge and discharge controller, and the rechargeable lithium battery are set in the monitoring box to ensure the internal components. Select the less disturbed area of ​​the landslide to establish the landslide field monitoring base station, erect the monitoring bracket, install the atmospheric rainfall monitoring terminal, the monitoring box and the solar panel, lightning rod and grounding conductor of the power supply subsystem. Among them, the atmospheric rainfall monitoring terminal is installed in an unobstructed position on the top of the monitoring bracket to ensure real-time and effective acquisition of atmosphe...

Abstract

The invention relates to a landslide intelligent monitoring system and method and belongs to the geological disaster intelligent monitoring technical field. The landslide intelligent monitoring systemand method of the invention are used for the intelligent monitoring and analysis of field landslides and do not need external power sources. With the landslide intelligent monitoring system and method of the invention adopted, landslide trigger monitoring based on induction factors and disaster-causing elements is realized; and the geological disaster intelligent monitoring closed loop structureof a landslide data processing and analyzing method is determined according to the surface deformation conditions of landslides. The system and method have the advantages of high integration, high intellectualization and universal applicability. With the system and method adopted, erroneous measurement and missed measurement in timed monitoring and waste caused by the transmission of a large quantity of useless data can be avoided.

Description

technical field [0001] The invention relates to geological disaster intelligent monitoring technology, in particular to a landslide intelligent monitoring system and method. Background technique [0002] Due to the wide distribution of landslides in my country and the high and steep slopes in the Three Gorges reservoir area and southwest, especially the slopes with rock mass as the main structure, the occurrence of geological disasters is closely related to rainfall, especially concentrated heavy rainfall in a short period of time ; while in the northwestern slopes with loess or soil as the main covering layer, the causes of geological disasters such as landslides are mainly due to the combined results of soil moisture content, increased self-weight, or low friction on the sliding surface. Moreover, some landslides in our country present the characteristics of high-level, high-speed and long-distance landslide-debris flow, which are not easy to investigate and monitor. How to...
