Embodiment Construction

[0008] In order to help readers understand the working principle of this scheme, the applicant feels that it is necessary to make some brief explanations in this regard. The working principle of this solution is different from that of ultrasound imaging, which is mainly realized based on the time of reflected waves. The present invention is mainly based on the acoustic physical properties of tires. Anyone who has played a musical instrument knows that the tightness of the strings in a stringed instrument has a great influence on the tone and timbre of the instrument. The tuner mainly adjusts the tone and timbre of the instrument by adjusting the tightness of the strings, which changes the acoustic characteristics of the instrument. The tone is the fundamental frequency, and the timbre is the harmonic; when people hit the strings in the same way and with the same strength, different strings have different tones and timbres. This program is designed with reference to this phys...

Abstract

The invention relates to a voiceprint automobile tire pressure monitoring device, which belongs to the field of automobile tire pressure safety monitoring technologies. Aiming at being capable of monitoring the inner pressure of an automobile tire outside the automobile tire at any time, the following measures are utilized: an ultrasonic generator and an ultrasonic receiver are arranged on the side of the automobile tire, the ultrasonic receiver is connected with an amplifier, the amplifier is connected with an A / D (analog to digital) conversion circuit, and the A / D conversion circuit is connected with an MCU (micro control unit). The MCU stores original voiceprint signals from the ultrasonic generator and data of echo voiceprint or voiceprint characteristics of the automobile tire under different inner pressure; and therefore the inner pressure of the automobile tire can be sensed outside the automobile tire at any time on the premise of not changing any structure of the automobile tire, and the traffic safety is facilitated.

Description

technical field [0001] The invention belongs to the field of automobile tire air pressure safety monitoring technology. Background technique [0002] When watching TV, we often see news about traffic accidents caused by car blowouts. In reality, such accidents are also common in driving. In fact, these tragedies are completely avoidable, but due to various reasons, they are repeated scene after scene around us, which is really distressing! There are many reasons for this, and many people only attribute it to the poor quality of tires, shoddy manufacture, aging tires and other reasons, but few people know that there is actually another very important reason, that is, the insufficient air pressure of car tires. Many people have a misunderstanding in this regard, thinking that the air pressure of car tires is high and it is easy to blow out. In fact, the opposite is true. Car tires with low air pressure are more likely to blow out than tires with high air pressure. The reaso...
