Some differences between ultrasonic rangefinder and laser rangefinder are introduced
The principle of laser rangefinder is the same as radio radar. After laser alignment is sent out, measure its reciprocating time, and then multiply by the speed of light to get reciprocating interval.Because the laser has the high direction, the high monochromatism and the high power and so on the merit, these about measures the distance interval, the determination policy azimuth, the enhancement accepts the system the signal to noise ratio, guarantees the measurement precision and so on is very key, therefore the laser ranging receives the attention day by day.
The laser radar developed on the basis of the laser rangefinder can not only measure distance, but also can measure the orientation, the speed and acceleration, has been successfully used in the ranging and tracking of artificial satellites, such as the selection of ruby laser laser radar, ranging scale of 500 ~ 2000 km, the error of only a few meters.At present, ruby laser, neodymium glass laser, carbon dioxide laser and gallium arsenide laser are often used as the light source of laser rangefinder.
Ultrasonic sensors are often used to detect distant objects, and because they are not optical devices, they are unaffected by color changes.However, ultrasonic sensors measure the interval according to the speed of sound, so there are some inherent defects that cannot be used in the following situations, while laser sensors do not have the following problems:
(1) when the policy to be tested is not in line with the transducer of the sensor.Because the ultrasonic inspection policy must be in the sensor with a deviation of no more than 10° Angle.
(2) occasions where visible light spots are required for location calibration.
(3) occasions where the required beam diameter is small.Generally, the diameter of ultrasonic beam is 0.76cm when it is 2m away from the sensor.
(4) windy occasions.
(5) vacuum occasions.
(6) large temperature gradient occasion.Because in this case there is a change in the speed of sound.
(7) occasions for rapid response of demand.
Laser rangefinder can effectively prevent the tower from tipping
Technology and the information age have narrowed the distance between people and countries.Nothing seems to hinder the relationship between the two relationships, but it is in production.Distance measurement is still a difficult problem to solve.For example, in the construction industry, tower crane is one of the most commonly used mechanical equipment.
Tower cranes usually have larger lifting capacity, larger working range and higher lifting height.It can realize the longitudinal and lateral transport of materials, and has been widely used in the construction industry.This large mechanical equipment is used in construction.This process does have its irreplaceable role.Help construction projects complete quickly and easily.
Tower crane is a tower crane structure.This type of equipment is very complex and involves high-altitude work, so it is likely that tower cranes will tip over.On the one hand, these accidents will affect the construction progress of the project, and on the other hand, it will bring huge loss of life and property to the country and people.Therefore, in order to ensure safety and minimize the loss of life and property, laser rangefinders are needed.Auxiliary equipment is used for detection and laser ranging is used for distance measurement.The state also has relevant provisions, tower crane equipment must be equipped with qualified testing equipment to pass the inspection.
Both products have their advantages and disadvantages. Although the tower crane has the disadvantage of being easy to tip over in the process of use, its strong bearing capacity still has an irreplaceable position in the construction industry. Is one of the common equipment.All products are found unsuitable in the process of use, and then they are improved to become more suitable products for our use.The same is true of tower cranes.In order to solve the problem of tower crane prone to tip over, adding laser rangefinder and using laser rangefinder to prevent tilt is the most commonly used method to solve this problem, which has been widely used now.The application has been proved to be practical in practice.
