What is the application of analytical laser rangefinder in the construction industry?
Building measurement is the first and most important process of building construction.With the development of society, more and more high-rise buildings in our country, in the construction and the decoration of the floor in the future, the measurement of the height of the building, the space between two points, the area, the use of materials, structural deviation, etc., are related to the safety of the whole floor building.At present, the most commonly used measurement things include all kinds of rangefinders, laser rangefinders, telescopic rangefinders, etc., using these measurement things, can reduce the measurement time together, make measurement more accurate.The company's laser rangefinder has been successfully used in the construction industry.
Laser rangefinder double injection of non-slip soft adhesive planning, so that users have a comfortable sense of holding hands.In addition, the compact and simple appearance of the laser rangefinder and the "measurement and targeting integration" plan make the laser and the line of sight in the same line, greatly reducing the error between the laser emission point and the line of sight, making the measurement results more accurate.
Laser rangefinder small volume, light weight, easy to carry, measuring range of 0.05-50 meters, the error is only plus or minus 1.5 mm, easy measurement of area, volume, the operation principle is to use the laser to the policy of accurate measurement of the interval of the instrument.When the laser rangefinder works, it shoots a very fine laser beam to the target. The laser beam reflected by the target is received by the photoelectric element.
Its large LCD backlit display allows you to easily read measurement data together with your eye alignment.In addition, the use of simple safety, only need to operate alone and do not need to use other things (such as ladders, etc.) can be completed all measurement work, even inaccessible parts can be easily handled, thus avoiding injury accidents at the maximum level.
Laser rangefinder can be applied to all kinds of construction projects, such as the construction industry various intervals, area, volume measurement, positioning formwork orientation, calculation of concrete casting quantity, etc.Decoration company USES its fast and accurate finish light steel keel positioning and device;In the telecommunication industry, this laser rangefinder can be used to finish all kinds of measurement work needed for cable and wire installation.When the electromechanical device, the laser rangefinder can ensure the length of pipe and the length of the device are the same, and ensure that the materials are in place and not wasted.
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.
