[ Focus on Chemical Machinery and Equipment Network ] China has a vast territory and complex geology.
Once severe weather such as heavy rain occurs, geological disasters will often occur in some provinces.
Every fierce disaster such as collapses, landslides, and mudslides has caused landslides and landslides.
Therefore, it is urgent to prevent and control geological disasters.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentOnce severe weather such as heavy rain occurs, geological disasters will often occur in some provinces.
Every fierce disaster such as collapses, landslides, and mudslides has caused landslides and landslides.
Therefore, it is urgent to prevent and control geological disasters.
The prevention and control of geological disasters is urgent
The prevention and control of geological disasters is urgent"Geological disasters" as a specialized term used to summarize collapses, landslides, mudslides, ground subsidence, ground fissures and ground subsidence have gradually been accepted by the government, society and academia.
my country is a country with frequent occurrence of natural disasters, especially geological disasters.
In the past few decades, a large number of geological disasters, such as collapses, landslides, and mudslides, have caused serious economic losses and brought serious damage to people's production and life.
For this reason, it is urgent to improve the geological disaster prevention system.

For this reason, it is urgent to improve the geological disaster prevention system.
According to statistics, in 2019, there were 4220 landslides, 1238 collapses, 599 mudslides, 121 ground subsidences, 1 ground fissure and 2 ground subsidences.
Geological disasters caused 211 deaths and 13 missing.
75 people were injured and the direct economic loss was 2.
77 billion yuan.

The seriousness of geological disasters cannot be ignored.
The relevant departments stated that when carrying out the prevention and control of geological disasters, we should not only pay attention to the early monitoring and prevention of geological disasters, but also improve the emergency and post-treatment level of geological disasters, and minimize the occurrence of geological disasters.
Chances and losses.
From the above data, it is not difficult to see that geological disasters will cause great harm to the safety of people's lives and properties, and how to manage and prevent them has become an urgent topic.

Build a monitoring system for disaster warning
Build a monitoring system for disaster warning *, Geological disasters have irresistible characteristics.
In the process of geological disaster prevention and control, disaster identification needs to be done, and the current situation of disaster occurrence can be effectively grasped by establishing an early warning mechanism.
In the process of geological disaster prevention and control, disaster identification needs to be done, and the current situation of disaster occurrence can be effectively grasped by establishing an early warning mechanism.
Among them, disaster early warning is an important prevention and control measure as well as a key technical measure.
It can effectively grasp the effectiveness of various geological disaster prevention and control through the establishment of a complete monitoring and early warning system.
Aiming at the hidden dangers of different types and scales of geological disasters, focusing on displacement, ground stress, pore water pressure, rainfall and other factors, a batch of safe, stable and practical technologies and products have been developed step by step and phased to improve the monitoring and early warning technology of geological disasters Equipment standardization, intelligence and industrialization level.

In addition, with the development of science and technology, satellite remote sensing and other technologies are used in disaster monitoring, which can monitor the magnitude of surface deformation and identify geological hazard risks, including information acquisition, transmission, storage, and processing.
The core component of obtaining information.
There are mainly cameras, multispectral scanners, imaging spectrometers, microwave radiometers, synthetic aperture radars, etc.

At present, in terms of ground disaster monitoring and early warning, *emphasizes the implementation of geological disaster risk control and disaster risk reduction as the goal, and makes full use of high-resolution optical and interferometric radar (InSAR) satellite remote sensing, aerial remote sensing, unmanned aerial vehicle and laser (LiDAR) Observation, etc.
* Applicable technical means, high-precision positioning service network, Digital Elevation Model (DEM) and other new technical means to further improve the national geological disaster prevention level.
Vigorously carry out pilot projects for universal monitoring and early warning equipment, and carry out concentrated tests on equipment performance, monitoring and early warning methods, and operation and management mechanisms.

Establish a monitoring and early warning system to realize integrated monitoring of "sky and ground", effectively improve my country's geological disaster defense capabilities, and reduce major casualties caused by geological disasters.
Geological disaster prevention monitoring instrument instrument also flourish
Geological disaster prevention monitoring instrument instrument also play an active role monitoring equipment
As an important part of the instrumentation industry, monitoring instruments play an extremely prominent role in environmental monitoring, geological disasters, industrial production, etc.
, ensuring the normal operation of people's production and life.
According to *statistics, a total of 274 geological disasters have been successfully forecasted nationwide, involving 9764 people with possible casualties, avoiding direct economic losses of 520 million yuan.
Compared with the same period of the previous year, the number of geological disasters and the number of deaths and missing persons caused by geological disasters decreased by 38.
9% and 36.
0% respectively, and the direct economic loss increased by 17.
5%.
Among them, various monitoring instruments showed their talents, so what kind of monitoring instruments are there?
