The power industry is a leading basic industry of the national economy and occupies an extremely important position in the national economy. Modern industry, agriculture, national defense, transportation, scientific research, and even the daily life of modern people cannot be separated from the power supply for a moment, and the demand and dependence on power are becoming more and more intense. A momentary interruption in the power supply may cause paralysis of all walks of life, chaos in the social and people's living order, and huge losses to the national economy. Therefore, power safety production is related to the national economy and people's livelihood and has particularly important political significance.

As we all know, the characteristics of power production are high automation. The power grid is composed of many power plants, transmission lines, substation facilities and power equipment. They are interconnected and mutually restricted to operate together, forming a very large and complex power production, circulation, distribution and consumption process. In this process, power generation, supply and consumption are carried out simultaneously. If an accident occurs in any link and cannot be eliminated in time, it may bring about a chain reaction, resulting in serious damage to the main equipment or large-scale power outages, and may even cause a catastrophic accident of the collapse of the entire network.
At present, my country's power industry has entered a new stage with "large units, large power plants, large power grids, high parameters, high voltage, and high automation" as its main features, which has brought new topics to power safety production and put forward newer and higher requirements.
Application cases of photometric ranging technology
In recent years, with the rapid development of science and technology, laser ranging technology has become the most accurate means of determining the orbit of space targets, which is conducive to the high-precision measurement and monitoring of space targets. In order to monitor the status of transmission lines in real time and efficiently in the power industry, laser ranging technology has gradually become a widely used means of accurately locating and ranging transmission line faults.
01 Span telemetry, measuring span
In HD ML mode, measure the wires at the two poles respectively to obtain the horizontal distance (span) between the two points.
02 Cross-span height
In VD ML mode, measure the output wires and any target respectively to obtain the vertical height from the line to any target.
03 Measure the height of cables, cement poles, and iron poles
In HT mode, measure the top and bottom of the poles respectively to obtain the height of the poles.
04 Transmission line clearance distance measurement
In VD ML mode, measure the transmission line and the top of the tree to get the vertical height difference (VD value) between the two targets.
05 Determine dangerous trees and safe distances
Stand at any position, measure the bottom of the tree and the power cable in SD ML mode to get the distance from the tree to the transmission cable, and measure the height of the tree again in SD ML mode to determine whether the tree is a dangerous tree. (SD straight-line distance VD height HD horizontal distance)
06 Azimuth measurement and line direction
In AZ mode, it can replace the compass to determine the direction of the target.
07 Line sag and layer distance measurement
In VD ML mode, measure the upper and lower wires to get the layer distance; in VD ML mode, measure the line and the lowest point of the transmission line to get the vertical.
08 Single-point horizontal distance and slant distance measurement
In HD/SD mode, single-point measurement of any target can get the horizontal and straight-line distance to the target and the height difference and pitch angle from the current height of the instrument to the target point.
