Design of automobile anti-collision system by using ultrasonic ranging transducerWith the continuous advancement of automobile technology, especially the development of autonomous driving technology, more and more distance detection equipment will continue to appear. At present, there are four main

Due to the strong directivity of ultrasonic waves, slow energy consumption, and long distances in the medium, ultrasonic waves are often used for distance measurement. For example, ultrasonic rangefinders and level measuring instruments can be realized by ultrasonic waves. Ultrasonic testing is ofte

The reversing radar of piezoelectric ultrasonic transducer is "reverse collision avoidance radar", also known as "parking assist device". It is a safety assist device when parking or reversing the car and other parts.It can inform the driver about the obstacles around with a sound or a more intuitiv

In daily production and life, ultrasonic distance measurement transducers are mainly used in car reversing radar, robot automatic obstacle avoidance walking, construction sites and some industrial sites such as liquid level, depth measurement , pipeline length, etc. occasion. There are currently two

Ultrasound refers to mechanical waves with a frequency higher than 20 kHz. In order to use ultrasonic waves as a detecting means, it is necessary to generate ultrasonic waves and receiving ultrasonic waves. The device that performs this function is an ultrasonic sensor, which is customarily called a

As the medium for transmitting information, ultrasonic is more and more important in various fields such as flaw detection, ranging, and speed measurement due to its direct and reflective properties and its characteristics that are not easily affected by external factors such as light and electromag

Ultrasonic ranging transducer at low SNR and low sampling rates based on cross-correlation function. The specific method is as follows the ultrasonic signal sent by the transmitter is used as a reference signal, and the output of the receiver is immediately sampled at the end of each transmission of

The principle of drone technology and ultrasonic ranging transducer demonstrates the loss feasibility of measuring the obstacles in the electrical circuit corridor; the third chapter mainly introduces the ultrasonic ranging transducer system equipment, including selection of UAV equipment parameters
