Application of Inclination Transmitter in Geological Disaster Monitoring and Early Warning System
At around 4 am on July 8, 2020, affected by the extreme heavy rain, a landslide occurred in Group 3 of Yuanshan Village, Dahe Town, Huangmei County, Hubei Province, causing 5 households and 9 people to be buried.
At around 18:05 on November 23, 2020, a high-level landslide occurred in the Dugong Group of Jiapuzi Village, Xuewalong Town (formerly Taka Township), Jiulong County, Ganzi Prefecture. The landslide occurred at an unplanned point. The volume of the landslide was about 79,000 cubic meters, which caused the damage to 3 houses of the residents below the slope. Due to early evacuation, 130 people from 35 households under threat were properly resettled, and the disaster did not cause casualties. The Taka River below the landslide body blocked the formation of a dammed lake, which is estimated to be 40 meters long and 7-8 meters high. At present, the river backwater is about 200 meters long, flooding 12 residential houses on the shore.
At around 13:40 on January 19, 2021, a landslide accident occurred in Chehe Town, Nandan County, Hechi City, Guangxi, resulting in the construction of vehicles and 4 people buried in the diversion project of the Luojiawan section of the Diaojiang tributary. Pressure. As of 5:34 on the 20th, the rescue was over and the accident resulted in 3 deaths and 1 injury.
Almost every time, large and small geological disasters occur, including landslides, mudslides, collapses, ground subsidence, ground subsidence and ground fissures, which seriously affect the regional economic construction and the safety of people’s lives and property. my country's mountains and hills account for about 65% of the country's land area, with complex geology and landforms, diverse climate types, frequent constituent activities, many hidden dangers of natural disasters, and wide distribution. It is one of the countries with the most serious geological disasters and the most threatened population in the world. Therefore, the establishment of an intelligent monitoring network for geological disasters is an inevitable measure and effective means to prevent the destruction of geological disasters.
After years of in-depth cultivation and accumulation in geological disaster monitoring, Kenda PeopleSoft has made full use of its own technical advantages to establish a set of scientific and complete geological disaster monitoring and early warning solutions to realize the scientific, informatization and standardization of geological disaster dynamic monitoring information. And visualization, to provide a scientific basis for disaster prevention and mitigation decision-making, and effectively improve the early warning and forecasting capabilities of geological disasters and rapid response to emergency disasters.
The program consists of an inclination transmitter, rain gauge, water level gauge, water pressure gauge, settlement gauge and a geological disaster monitoring platform. It can be adapted to local conditions and integrates deep displacement monitoring, landslide groundwater seepage pressure monitoring, and landslide rear edge tensile crack displacement monitoring , Rainfall monitoring, surface water level monitoring, pressure monitoring, surface water infiltration monitoring and other monitoring equipment, provide comprehensive and accurate data support for relevant departments to more comprehensively analyze the causes of landslides, early warning or engineering treatment design. Among them, the tilt angle transmitter can effectively monitor the tilt angle of the ground.
The inclination transmitter is a standard industrial dual-axis inclinometer. It can judge the inclination state of equipment, mountains, or dams by detecting the inclination angle in the use environment. It can be used outdoors for a long time. It is widely used in industrial inclination measurement and dangerous building monitoring, ancient building protection monitoring, bridge tower inclination measurement, tunnel monitoring, dam monitoring, weighing system tilt compensation, drilling tilt control and other industries. It is safe and reliable, beautiful in appearance, and easy to install.
Functional characteristics of inclination transmitter
1. Kalman filter algorithm is used to make the angle value collected by the device accurate and stable.
2. It has a wide angle measurement range, and the output signal has good linearity, which can be used in most environments.
3. It adopts a dedicated 485 circuit, a standard ModBus-RTU communication protocol, and the communication address and baud rate can be set.
4. 5~30V DC wide voltage range power supply.
5. It has the characteristics of wide measuring range, good linearity, easy to use, easy to install, and long transmission distance.
At this stage, conventional monitoring methods and technologies for geological disasters have become mature, and related detection equipment and their performance have also been greatly improved. With the continuous development and progress of science and technology such as informatization and intelligence, the detection technology of geological disasters in the future will gradually achieve the monitoring goals of high precision, automation and real-time.
