First of all, I would like to express my sincerest prayers to Henan and other places that are suffering from the rainstorm disaster and hope that they can safely ride out the rainstorm as soon as possible.
As Internet technology service, over the past few years, the depth of the industry involved in geological disaster monitoring scheme, so also want to talk in front of natural disasters, we how to make use of geographic information technology, Internet of things, such as large data, make more timely and accurate warning to geological disaster monitoring, reduce the personnel and property losses.
Geological disaster monitoring is the real-time automatic monitoring landslide, collapse, debris flow, ground fissures, ground collapse, ground subsidence, earthquakes, floods and other disasters rainfall is given priority to, through the automatic monitoring, construction of geological disaster monitoring from data acquisition, storage, display, transmission and computing to analysis for the integration of informationization, visualization and intelligent service platform, It provides reliable data and scientific basis for the research and analysis of geological disaster mechanism, early warning and forecasting, prevention and control projects, etc.
Take the heavy rainfall in Henan Province as an example. At present, urban roads and subway lines have been hit by heavy rain, while remote mountainous areas and other places are facing more serious geological disasters such as mudslides and landslides. Therefore, it is particularly important to deploy geological hazard monitoring system well in advance.
On March 19, 2021, the Ministry of Natural Resources issued the Notice on Doing a Good Work of Geological Disaster Prevention in 2021, requiring all provinces to earnestly do a good job in geological disaster work, among which Sichuan, Yunnan, Guangxi, Gansu, Shaanxi, Shanxi, Qinghai, Hubei and other provinces were designated as areas for the general monitoring project in 2021.
The first step of disaster early warning: integrate geological disaster safety early warning and monitoring equipment

The second step of disaster warning: stable and efficient collection and transmission of monitoring content data
After the geological disaster safety warning and monitoring equipment integrated by the above sensors is installed at the monitoring point, the next issue to be considered is the acquisition and transmission of data, that is, which transmission protocol to adopt for stable and efficient reporting;
The diagram shows the framework diagram of geological hazard monitoring system
In this system architecture, considering the signal problem and transmission difficulty in remote areas, NB/4G dual-link low-power Internet of Things data acquisition terminal for outdoor monitoring field is used, which supports the wireless transmission of NB-IoT/4G network of China Unicom and Mobile Telecom.
The product adopts high-performance ESP32 dual-core processor and industrial-grade NB-IoT/4G solution, with wide coverage, low cost, low power consumption, low latency and other characteristics, supporting two-way data transmission.
The third step of disaster warning: geological cloud system real-time monitoring and early warning
In the “geological geological disaster monitoring and early warning information system cloud”, for example, the system can realize the monitoring objects of automatic, continuous, real-time monitoring, provide monitoring data shall be carried out in accordance with the unified data format standard real-time receive and provide huge amounts of data storage, data retrieval, visualization, early warning analysis, early warning function such as news, achieve the goal of geological disaster monitoring and early warning, To provide data support for disaster prevention and mitigation.

To sum up, prior to the arrival of natural disasters, early warning and intervention can be achieved through technical means, so as to greatly reduce the casualties and impacts of disasters. With the frequent occurrence of various types of natural disasters in cities and mountainous areas, the deployment of a more accurate and complete disaster monitoring system is an important means to ensure the safety of people’s lives and property.
