Description

FIELD OF THE INVENTION The present invention relates to a tire condition monitoring system using an Internet access device,

The present invention relates to a method and apparatus for controlling a tire state using an Internet access device for transmitting a result of a tire evaluation to a portable device after a state of a tire is transmitted to a processing server after obtaining a still image of the tire using a portable device capable of communication and photographing System and method thereof.

BACKGROUND OF THE INVENTION [0002] Treads made of tread, carcass, and bead are generally one of the major components that determine the driving safety of an automobile. Especially, Braking force and steering performance.

Tread wear of an automobile tire may cause uneven wear due to driving habit of a driver of an automobile, an automobile condition, and an air pressure condition of a tire as well as natural wear which tread wear occurs uniformly depending on the use time of the tire, Wear and lap wear also have a significant impact on vehicle safety.

Inadequate air pressure or excessive air pressure of an automobile tire affects the braking force and steering performance of an automobile, which is an important factor for safe driving. In addition, the air pressure condition of the automobile tire greatly affects the tire wear and the life of the tire. In addition, the aging phenomenon of the tire caused by the long use of the automobile tire also has a great influence on the safe driving of the automobile. The aging phenomenon caused by the exposure to sunlight and the heat due to the long use of the tire, It can be confirmed as a micro cracking phenomenon of the side wall portion.

In addition to the way in which the tread wear, air pressure, and cure state of a car tire were judged subjectively based on the driving experience of the driver of a motor vehicle, in the conventional automobile tire related industry, the tire tread wear and air pressure state We have developed a number of devices to prevent car accidents by warning the driver of the condition of the tires in advance. For example, a tire pressure monitoring system (TPMS), which measures the air pressure of a conventional tire and informs the driver of the vehicle in real time, is equipped with a pressure and temperature sensor inside the vehicle tire, Value to the driver in real time, but the automobile operator had to purchase an expensive automobile tire equipped with a pressure and temperature sensor, compared to a general tire without a pressure and temperature sensor.

Conventionally, a device for inspecting a tread of an automobile tire is irradiated (irradiated) to the tire using ultrasonic waves, radiation or a general light source (laser source), and the reflected amount is measured, However, this is generally used as a method for inspecting the defective rate of the manufactured automobile tires in the automobile tire manufacturer, and the driver can not directly determine and check the condition of his / her automobile tire during operation.
