Common Measurement Challenges Faced In Daily Life
In daily life, interior designers and architects often encounter problems when designing and decorating processes, which cause headaches due to various measurement difficulties or hidden safety hazards that cannot be found near the measurement site.
Now, the laser distance meter can solve similar problems for you, and can easily measure the distance of the position or length that cannot be close to the object.
Hand-held laser distance meters, such as stairwells, elevators, and other areas that are not in direct contact with the measurement target, can help you, replacing the traditional box-shaped rule measurement and saving manpower.
Laser distance meter is a new high-performance handheld distance meter launched in recent years. It uses a patented design and can measure the range from 0.05 to 200M. The measurement accuracy is ±1±1.5MM. It measures quickly, is easy to use and has a compact design. Carry.
With this laser distance meter, you no longer need a lifting platform or a telescopic ladder to measure the volume of a house or stairwell, it only takes a few seconds to measure the reading.
In traditional measurement, there is a potential safety hazard that the measurement location cannot be approached. The laser distance meter has a red laser point, which allows you to clearly understand the location of the measurement point. It only needs one person to operate it and no other tools (such as a ladder) are needed. Even in hard-to-reach areas, all measurements can be performed to prevent the greatest degree of injury.
In addition, in addition to a pocket-sized portable design, the distance meter also has a length addition and subtraction function, so it does not have to lie on the ground because it is measuring the ceiling.
The large LCD backlit display and laser distance meter allow you to easily read the measurement data while aiming at the target. Using a laser distance meter, people can start to work at twice the speed of traditional methods. Measure distance, area, volume, triangle position, Pythagorean theorem, etc.,
It can be widely used in the following fields:
1. Construction industry: building distance measurement, house acceptance, pouring area, volume, etc. calculation.
2. Indoor industry: no area, door and window, bracket size measurement.
3. Measurement industry: direct measurement of various distances or distance measurement that cannot be directly measured.
4. Electromechanical industry: installation of telecommunications equipment, construction of equipment distance measurement, durability measurement, distance measurement that cannot be directly measured.
5. The public security system measures the distance of incident handling.
The principle and application of Laser Distance Meter
Laser distance meter, I believe you will not be unfamiliar, today this article collects some knowledge about the principle of distance meter, I hope this article can have some reference value for you. Let us make a simple comparison and explanation of the differences between the principles and applications of different distance meters.
The working principle of laser distance meter
When the laser distance meter is working, the laser diode first aims at the target and emits laser pulses. The laser light reflected by the target is scattered in all directions. Part of the scattered light returns to the instrument receiver and is imaged on the avalanche photodiode after being received by the optical system. The avalanche photodiode is a built-in optical instrument with amplifying function, so it can detect very weak light signals. The target distance can be determined by recording and processing the elapsed time from the light pulse to its return to reception. The laser distance meter must measure the transit time very accurately because the speed of light is too fast.
Laser ranging can be used for accurate positioning because of its long measuring distance (tens of meters to hundreds of meters), high accuracy, and low interference. Due to its stable performance and high measurement accuracy, laser ranging is currently a commonly used ranging tool on the market.
Principle of Ultrasonic laser distance meter
Ultrasonic waves have strong penetrating power to liquids and solids, especially solids that are opaque to sunlight, which can penetrate to a depth of tens of meters. When ultrasonic waves touch impurities or interfaces, they will produce obvious reflections and form echoes. When they touch moving objects, they will produce Doppler effect. Therefore, ultrasonic testing is widely used in industry, national defense, biomedicine and other fields. Ultrasound is used as a test method, and ultrasonic waves must be generated and received. The equipment that realizes this function is an ultrasonic instrument, usually called an ultrasonic instrument or an ultrasonic probe.
1. In terms of accuracy, the measurement accuracy of the ultrasonic distance meter is at the centimeter level.
2. As far as the measurement range is concerned, the measurement range of an ultrasonic range finder is usually within 80 meters, while the measurement range of a handheld laser range finder is up to 200 meters.
3. The ultrasonic distance meter is easy to report errors. Since the ultrasonic distance meter emits sound waves, it has the fan-shaped emission characteristics of sound waves. When the sound waves pass through more obstacles, the reflected sound waves will be more, and there will be more interference, and it is easy to report errors.
4. The price of ultrasonic range finder ranges from tens of yuan to hundreds of yuan.
The working principle of infrared distance meter
Infrared distance meter: It uses the principle that the intensity of different reflections when the infrared signal encounters an obstacle is also different to detect the distance between the obstacles. The infrared distance meter has a pair of infrared signal transmitting and receiving diodes. The luminous tube emits infrared signals of a specific frequency. The receiving tube receives the infrared signal of this frequency. When the infrared detection direction encounters an obstacle, the infrared signal is reflected back and received by the receiving tube. After processing, the infrared signal is returned to the robot host through the digital instrument interface, and the robot can use the infrared return signal to recognize changes in the surrounding environment.
