1.Advantages of the product
1. Cost advantage: The price of a single sensor is low.
2. Precision advantage: Each sensor is an independent system, and the accuracy of each system is within 1%, that is, weak mountain/building movement can be detected.
3. Flexibility advantage: 3D mountain/building map can be made, each sensor can be visualized, and the default sensor’s initial return value is set to 0. Based on the fact that the liquid surface is unchanged relative to the altitude, when a place collapses, liquid will be injected into the place and the liquid level will increase; when a place rises, the liquid will decrease and the liquid level will decrease.
4. Use time advantage: the use of solar panels to charge the battery, to ensure that the sensor 24 hours uninterrupted work, while its own low power consumption and low power mode, sleep mode.
2.Concrete implementation method
2.1.landslide
Base station: has a large capacity of water, and the water level is not changed, and is embedded deep in the mountain, not affected by landslides.
Slave Station: Each slave station is a stainless steel tube container with a liquid level sensor, built on the mountain surface and at the same altitude reference line with the base station. When the altitude of the slave station drops, the falling displacement relative to the altitude reference line is equal to the rising displacement of the slave station liquid level, assuming that the liquid level changes from 50cm to 80cm. It can be inferred that the block from the station subsidence 30cm.
Water pipes: Water pipes are connected to the bottom of each slave station, and need to be as safe from landslides as possible, and need to be longer than the distance from the slave station and more tough materials to avoid breaking as much as possible.
Altitude reference line: The lowest elevation of the base station is the altitude reference line, and the initial position of each sensor should be on the altitude reference line.
Level reference line: The position of the liquid by default. The level reference line does not change as it sinks from the station. The distance between the level reference line and the altitude reference line is always the same.
The figure below shows the situation of the sensor after the landslide of the mountain, the water stored in the base station is poured into the slave station, so that the liquid level of the slave station is increased, and the sensor level reading is increased until the pipe is filled with water. The landslide may cause the pipe or water pipe to break, which will make the base station level will continue to drop, from the station level first increase and then decrease, from the station level to 0. The above are possible abnormal phenomena that require software to identify and alarm.
2.2.Bridge/tunnel collapse
Base station: With a large capacity of water, and the water level is unchanged, the two base stations should be installed on the surface or elevated at the same elevation.
Slave station: Each slave station is a stainless steel tube container with a liquid level sensor, which is built on the side of the bridge body and is at the same altitude reference line as the base station. When descending from the slave station, the descending displacement relative to the level reference line is equal to the rising displacement of the level of the station. If the level changes from 50cm to 80cm, it can be inferred that the block where the station is located sinks 30cm.
Water pipes: Water pipes are connected to the bottom of each slave station to avoid breakage as much as possible.
Altitude reference line: The lowest elevation of the base station is the altitude reference line, and the initial position of each sensor should be on the altitude reference line.
Level reference line: The position of the liquid by default. The level reference line does not change as it sinks from the station. The distance between the level reference line and the altitude reference line is always the same.
As shown in the figure: When a certain section of the bridge body sinks or is raised, the liquid level in the pipeline will rise by 30cm when the slave station sinks by 30cm, and the liquid level in the pipeline when the slave station is raised by 30cm will decrease by 30cm.
2.3. The foundation of the building collapsed
Base station: A large capacity of water with a constant water level, mounted on the surface or elevated.
Slave station: Each slave station is a stainless steel tube container with a liquid level sensor, built around the building, and is at the same elevation level with the base station. When descending from the station, the descending displacement relative to the horizontal line is equal to the rising displacement of the station’s liquid level. Assuming that the liquid level changes from 50cm to 80cm, it can be inferred that the block where the station is located sinks 30cm.
Water pipes: Water pipes are connected to the bottom of each slave station to avoid breakage as much as possible.
Altitude reference line: The lowest elevation of the base station is the altitude reference line, and the initial position of each sensor should be on the altitude reference line.
Level reference line: The position of the liquid by default. The level reference line does not change as it sinks from the station. The distance between the level reference line and the altitude reference line is always the same.
As shown in Figure: When a certain point of the building sinks or bulges, the liquid level in the pipeline will rise by 30cm when the slave station sinks by 30cm, and the liquid level in the pipeline when the slave station bulges by 30cm will decrease by 30cm. At the same time, the inclination Angle of the building can be calculated.
Finally, the above solutions can be realized using Kacise capacitive level meter.
