What is the development prospect of laser rangefinder in China?
As the world's factory, laser rangefinder industry has a good prospect and potential. Since the 21st century, China's laser market has shown a steady and rapid growth trend.Despite the rapid development of the industry, we should be aware that China's laser industry started late, the foundation is weak, and the gap with the world's major countries is still large. For example, China's laser processing systems are quite different from those made in advanced countries.It accounts for only about 2% of global sales.Mainly reflected in: high-end laser processing system less, uneven;The laser of the main component of the laser rangefinder is not closed;There is a big gap in laser micromachining equipment.
Major problems remain:
There are fewer core technologies: many of the key infrastructure technologies have not been solved, and some technologies have even regressed.At present, most of the core technologies of domestic laser rangefinder are imported, and the competitiveness of the products is insufficient.
The combination of product research and development is not satisfactory: China still leads the world in academic research on laser rangefinders, but the industry is very backward, intellectual property rights and patent results are not well protected, and many advanced laser technologies have not been translated into industrial applications.In addition, academic openness is not enough, and innovation is inefficient due to the fear of technological loss.
Weak innovation ability, poor support ability: the system support ability is not high, the innovation ability is insufficient, mostly is the traditional structure type.At present, most industries are integrated industries of optical machinery and electronic computing, and the combination of domestic laser and other industries is very bad, low degree of intelligence and automation, which increases the difficulty of users.
From a technical management perspective, there is a lack of a good evaluation system: there are no national standards, the evaluation system "equivalence" conversion is improper, not flashy.The existing evaluation system is a kind of self-cycle, which leads to the insufficient quality supervision of laser products and is not conducive to the development of laser industry.
Detailed explanation of the operation method of laser rangefinder
Laser rangefinder usually USES two methods to measure distance: pulse method and phase method.
The pulse rangefinder works like this: the laser emitted by the rangefinder is reflected from the measured object and then received by the rangefinder, which records the time of the laser's reciprocation.Half the product of the speed of light and the time to return is the distance between the rangefinder and the object being measured.
The accuracy of measuring distance by pulse method is generally about +/-1 meter.Other, the blind area of this kind of rangefinder is about 15 meters.
How to use the rangefinder:
Firstly, arrange theodolite on the station, center and level it, place the main equipment of the rangefinder on the theodolite bracket, lock it with the fixing screw of the coupling, insert the battery into the bottom of the main engine and fasten it.Arrange the reflector at the policy point, center, level, and point the mirror toward the host.
Aim the center of the board with the cross thread of theodolite, and measure the perpendicular Angle alpha.Together, observe and record temperature and barometer readings.To observe the vertical Angle, air temperature and air pressure, the purpose is to correct the tilt, temperature and air pressure of the distance measured by the rangefinder, so as to get the correct horizontal distance.
Press the "PWR" key on the power supply to start the machine, the host will self-check and flash the original set temperature, pressure and prism constant value, and the self-check will flash "good" in the future.
To correct the set value, press "TPC" and enter the temperature, pressure or prism constant (usually through "ENT" key and digital key).In general, just use the same kind of reflector, the prism constant is the same, and the temperature and pressure may be different for each observation, which needs to be set from scratch.
Adjust the hand wheel (or theodolite horizontal fretting screw) and the pitch fretting screw of the main engine by scheduling the altimeter axis, so that the rangefinder telescope can accurately aim at the prism center. n the case of flashing "good", accurate aiming can also be judged according to the sound and motion of the buzzer. The stronger the signal is, the bigger the movement and motion is. The micro-moving rangefinder from left to right makes the maximum movement and motion of the buzzer.
Application field of laser rangefinder
Laser rangefinders are now widely used in the following fields: electricity, water conservancy, communications, environment, architecture, geology, police, fire, blasting, Marine, railway, counter-terrorism/military, agriculture, forestry, real estate, leisure/field sports, etc.
