Abstract

A wireless tire pressure and tire temperature monitoring system, including a wireless monitoring and transmitting device mounted on a tire wheel rim, and a digital receiving-display device mounted on the driver's seat on board. The wireless monitoring and transmitting device further includes: a pressure sensor, a temperature sensor, a differential amplifier connected to the pressure sensor, an attenuator connected to the temperature sensor, a microcontroller receiving pressure signals from the differential amplifier and temperature signals from the attenuator, where the signals are transmitted to the digital receiving-display device by a transmitter and a filter through a dielectric resonator antenna so as to allow the driver to comprehend the real-time tire pressure and temperature. Furthermore, an eccentric switch is connected to the microcontroller such that the monitoring system is automatically switched on when the speed is higher than a predetermined range (such as 10-20 km per hour), and switched off when lower than the range for a fixed period of time (such as 5 minutes).

Invention 锊 [Technical Field of the Invention of the Invention] —Special mention '= provides a wireless tire pressure driving device. I can drive people to control the safety of wheels, wrinkles, and passengers in the car. By. [Previous technology] According to the increase of the economic power of the people in general transportation and automobiles, the country is important to the majority of consumer groups who own cars, and it affects driving safety due to the state of God and caution when driving. In addition, whether tires, brakes, etc.) can be used for tires, in addition to whether the tread texture is deep enough to drive safely, where the tire pressure is too high or only 'when the tire pressure is at a standard value, the tire = too high pressure, Although the rolling resistance is small, Gu easily causes the center of the crown to wear, and it is also easy to be damaged when external force is applied, and it is also easy to cause turtle resistance, increase fuel consumption, and increase friction on both sides of the crown to delaminate the tread or ply. When the car is running, the constant friction of the inner curtain of the tire will cause the temperature of the tire to rise. In the previous case, the “18, 6905” patent case was announced, that is, a car that can detect and monitor the tire temperature and the tire pressure and the safety of the car is normal, except that there are still cars that are functioning normally. In addition, there are insufficient tires, which are both excellent tires and ground due to tire surface cracks. The relative increase in tire damage is high. The tire temperature number "tire pressure tire tire pressure measurement system, full tire temperature conditions, comfortable number and Yuean arrived in the driver ’s own department of its functions, pressure and tire temperature will cause wheel energy The surface contact surface can be added when the surface tension is insufficient, and at the same time, it is easy to warn whether the tire indicator is too low, especially to ensure and facilitate the increase. The correct ground is the most precise component (such as among them) The wheel will affect the damage of the tire. The volume is reduced, the size is large, and the rolling is easy to cause the tire temperature surface and the ground to explode.
