Distance measurement is a basic and commonly used function of laser rangefinder. This function seems simple. You only need to press a button and the instrument will display the measurement results on the screen.
However, this very common function may have different meanings in different measurement modes, implying different measurement functions: horizontal distance, slope distance, height difference, angle... Just like the figure below. If the surveyor does not understand the specific application of various functions of the laser rangefinder, he may make mistakes in the measurement.
Today we will share with you the function of the onick B series laser rangefinder (the function of measuring height difference between any two points), so that you can learn more comprehensively and deeply about the application knowledge of laser rangefinder.
It should be noted that the VD ML mode of the onick B series laser rangefinder is applicable to the situation when both target points can be seen (that is, the two target points can be seen and the laser can hit the two target points).
The onick B series laser rangefinder, with its spatial arbitrary two-point measurement mode, two-button operation, fast response and high accuracy, has been widely used in process design, production activities and daily life.
1. VD ML mode in the power industry
In the power industry, this function of the laser rangefinder can be used to measure the crossing height, transmission line clearance distance, line sag, layer distance, etc.
In VD ML mode, the vertical height from the line to any target can be obtained by measuring the transmission line and any target separately.
In VD ML mode, the vertical height difference (VD value) between the two targets can be obtained by measuring the transmission line and the top of the tree separately.
In VD ML mode, the layer distance can be obtained by measuring the upper and lower wires separately; the line sag can be obtained by measuring the line erection point and the lowest point of the transmission line separately.
2. VD ML mode in the safety supervision industry
In the measurement work of the safety supervision industry, the VD ML function of the laser rangefinder can be used to measure the height of the mine at two points, providing strong data support for safety supervision work.
In VD ML mode, the vertical height of the mine can be obtained by measuring the top and bottom points of the mine separately.
3. VD ML mode in the geological industry
In the exploration and measurement work in the geological industry, the VD ML function of the laser rangefinder can be used to measure the height of the mountain or rock layer at two points, greatly improving the efficiency of geological exploration.
In the VD ML mode, the top and bottom points of the mountain or rock layer are measured respectively to obtain the vertical height of the mountain or rock layer.
4. VD ML mode in the environmental protection industry
In the measurement work in the environmental protection industry, the VD ML function of the laser rangefinder can be used to measure the height of the chimney at two points.
In the VD ML mode, the top and bottom points of the chimney are measured respectively to obtain the vertical height of the chimney.
5. VD ML mode in the transportation industry
In the measurement work in the transportation industry, the VD ML function of the laser rangefinder can be used to measure the vertical distance between the high-speed rail line and the roof of the car at two points, which perfectly solves the problem of measuring the vertical distance between the high-speed rail line and the roof of the car.
In the VD ML mode, the lowest point of the high-speed rail transmission line and the highest point of the high-speed rail train are measured respectively to obtain the vertical distance between the high-speed rail transmission line and the roof of the train.
6. VD ML mode in the oil exploration industry
Using this function, the oil exploration industry can measure the height of the oil tank at two points, greatly improving the measurement efficiency and reducing the difficulty of oil exploration.
In VD ML mode, the top and bottom points of the oil tank are measured respectively to obtain the vertical height of the oil tank.
7. VD ML mode in the water conservancy industry
In the measurement work in the water conservancy industry, the VD ML function of the laser rangefinder can be used to perfectly measure the height from the water surface to the bottom of the bridge at two points, greatly improving the work efficiency of water conservancy projects.
In VD ML mode, the bottom of the bridge and the bottom of the pier are measured respectively to obtain the vertical height of the water surface from the bottom of the bridge.
8. VD ML mode in the municipal industry
In the municipal industry, using this function of the laser rangefinder, the municipal industry can measure the height difference between buildings at two points, measure the height of street lights at two points, etc.
In VD ML mode, the top points of buildings are measured respectively to obtain the vertical height difference between buildings.
In VD ML mode, the vertical height of the street lamp can be obtained by measuring the top and bottom points of the street lamp respectively.
