It is difficult to control the fall, even if the car is stepping on the fuel slam, although it is accelerating, it is sensitive, and it runs lightly-Tian = when it is too big: it is uncomfortable when it hurts. In addition, if it moves often, it will cause rubbing or collision. It ’s difficult to control the situation; it ’s not easy to control the steering wheel. Under the circumstances, heavy traffic and high-speed driving are prone to two tragedies. K According to the reasons for the turnover of the Ministry of Communications in 86 ~ 88, the vehicle + Knife guide: In 8369, τ ,,, vehicle tires are unrolled or burst about 0.6%, suffering from the pain of% life Liesie Bao ^ Μ _ + μ η], and this pen is mostly directly related to improper tire pressure. " Relationship, so the _ question can not be ignored; there is a straight voice Two: The traditional method of checking tire pressure like TT, most of them are: Two 'connect the tire valve between the vehicle stop for detection, the previous inspection customs monitoring' Therefore, it is necessary to develop routine driving and otherwise, once forget to check , The tire pressure is not normal: 2 :: Causes a car accident. Therefore, there are those who are engaged in this industry = 1 or installed on their air nozzles. _ Pressure sensor and radio transmitter. If the patent case No. 323600 is examined, a "tire" is installed on the tire air valve 593001. The circuit device of the pressure alarm device "means that the pressure signal sensed by the pressure sensor is transmitted out. The radio frequency carrier mode is provided with a radio receiver and display. After the signal transmitted from the transmitter in the car room, it is wireless, After receiving the relevant information, the tire pressure warning device of the demodulation type of the two-mile unit demodulation type on the display shows the tire pressure condition on the display. Both have the following problems: Dagger Radio 1; Located on the mouthpiece '1 requires battery power to operate, α or long-term continuous operation, because of its short life and limited replacement power, it is expected that there are many doubts. Change the battery frequently and not 2: The internal temperature of the tire is very high during driving, which is extremely detrimental to the stability, reliability, and life of the battery. Two ';;:, road failure is not detected, but it is the same as if no tire factory is set up = evil, more dangerous. I 3 is not installed. 3 The electric and industrial design is only for transmitting when the tire pressure is too low or too high. 2 1 :: electricity, ::: = ?: no radio frequency signal is always emitted, = no judgment. The failure is the same as the “warning device is normal or not”; if the tire pressure signal is transmitted in a “ΐ” way, each tire must be coded or added with a crying carrier frequency to distinguish and not interfere, but ， ^ σ. The complexity and production cost of the circuit. m is used in the most power-saving state, its electricity is more than two to six months, its cost is not low, and the operation is troublesome. Ht? "Speed running, dynamic zero load bearing heavy load and impact ^ and σM warning device to increase tire pressure, installation is more τ and easier, not to mention the mass distribution is not serious Both, the dynamic balancing disc explodes, which causes strong vibration when the tire is running, which has the risk of accelerating tire damage and puncture. • In addition, when the tire is punctured or the tire is replaced, it is easy to affect or damage the installation. 6 593001 Transmitting devices, but the maintenance and calibration of sensors and transmitting devices are not easy. [Summary of the Invention] Based on the above-mentioned 'in order to meet the actual needs of the tire pressure (Tire pressure) warning device, but also to eliminate the various problems existing in the prior art, create People are determined to create a "tire tire pressure monitoring method and device" (Tire

It is hoped that "the potential danger of the workshop due to inadequate tire pressure" can be created in the case of the device, and most of them are prevented in Wei Di, and then the automobile is used as an example. This method and device for monitoring tire pressure 』Is composed of an annular pressure bladder 4 (Hollow Annular Pressure Cell), a displacement sensor 5 (Displacement Sensor), a signal processor 6 (Signal Processor), and a tire pressure display 7 (Tire

As shown in FIG. 3, the synchronous operation is performed. The annular pressure bladder 4 is vented to the outer wall 4-9. Ports 4-5 are connected by the air inlet j (Air Inlet) of the connecting tube 3 and the tire 2 or the special air port 2-2, as shown in Figures 1 and 3. Therefore, the internal pressure of the two must be equal; The pressure sensing surface of the pressure bladder is parallel to the fixed surface 4-7. It is a concentric wavy diaphragm 44 (Diaphragm), which can adjust its position linearly according to the internal pressure. When the pressure is large, it moves in the direction a. The hour moves in the direction of b. As shown in Figures 1 and 4, the dashed lines inside and outside the diaphragm 4-1 indicate the position where the pressure change of 7 593001 diaphragm 4-1, so as long as you monitor its position, you can know the corresponding tire. The corresponding relationship of pressure is shown in Figure 2A. The displacement sensor 5 (Displacement) is fixed on the attachment 2-6 of the tire support shaft 2_3, and the metal diaphragm 44 (Diaphragm) of the annular pressure bladder 4 maintains a small gap 4_4 (in p), but does not touch ( Non-Contact). When the tire pressure (g_ressure) increases-the gap decreases; ‘Conversely, when the tire pressure decreases, the gap increases, which is an inverse relationship (ρ α G-1) as shown in Figure 1B. The displacement sensor 5 is a contactless inductive type metal sensing device, which is very sensitive to the approach of metal due to the eddy current effect. Therefore, when the gap 4_4 changes with the change in the tire pressure, the excitation voltage 6-1 (Vexe) provided by the signal processor 6 of the displacement sensor 5 also generates an amplitude modulation phenomenon due to the eddy current effect. The latter signal (Modulated signal) is specially called "modulated signal" 5-1 (Vsig),... See Figure 1. When the gap 4-4 (Q_ap) increases, the eddy current effect weakens, The "signal" 5-1 (Vsig) also increases. Conversely, when the gap 4_4 (Vsig) decreases, the eddy current effect increases, and the "adjusted signal" 5 -1 (Vsig) also decreases. (Vsig) is proportional to the gap 4-4 (Gap) (VaG), while the internal pressure of the annular pressure bladder 4 and the "adjusted signal" 5-1 (Vsig) are linearly inversely proportional ρα ν — -1 ^ As shown in Figure 2C, as long as the "adjusted signal" is known, the tire pressure (Tire Pressure) can be obtained. "But for practical and habitual reasons, an inverter (Inverter) is installed in the signal processor to obtain an" inverted signal "Μ. The parent uses = Vng · 1 to make it proportional to the pressure (P). The relationship, that is, Pα, is shown in FIG. 2D, the greater the tire pressure, the greater the signal, and conversely, the smaller the tire pressure, the smaller the signal. 》 The signal processor 6 provides the excitation signal 6-1 of the displacement sensor 5 and demodulates, filters, filters, amplifies, and scales the "modulated signal" 5-1. , To the tire pressure display 7; and the tire pressure display is installed on the front panel of the driver's instrument 8 593001: analog or digital display of tire pressure. In short, by the composition of the above-mentioned components, when the tire pressure ^ of the tire 2 changes, the diaphragm 4_ 丨 of the annular pressure bladder 4 generates a ▲ corresponding displacement in the axial direction, and the displacement sensor 5 monitors this displacement 2. The second tire pressure signal 5-1. After the tire pressure signal is processed by the signal processor 6, the tire pressure signal is input to the tire pressure display 7 to display the tire pressure status. Therefore, turn on the start switch 1 of the car power source 9 〇, four: round moon. The tire pressure status is clear at a glance, and it is advisable to drive. See the diagrams in Figure 1, Figure 5, and Figure 6 for explanation. Figure 4A of the figure-like 4 waste 6 is composed of a ring-shaped Λ 疋, a fixed ring 4-6 parallel to the ring-shaped transmission into the in-plane threat 4-8 and the outer wall 4-9; The inner wall 4-8, y dagger 4 -... the sensing surface 4_7 is tightly connected to form the airbag 4, 10 edges of the outer wall 4 9 == there is a rolling center 5, and the straw is connected by the connecting tube 3 and the tire. The air pressure in the airbag 4-10 of the two L-force airbags 4 and the tires, and the good-looking F⑮ / ,; the sensor surface is specially designed to be-concentric waves = set. Therefore, as long as the sensing surface can know its internal pressure, the tire pressure is also known. < m 罝 ta Another embodiment of the annular pressure bladder 4, such as the inner wall 4-8, the outer wall 4-9 and the toilet Yin Zongchengguang1.

The pressure change inside the annular pressure airbag 4 causes the volume to change, and then changes to a one-dimensional displacement. The process is linear conversion That is, △ P = k * △ v = k * Α * △ [, which is why the annular pressure bladder is a good "pressure-position sensor".

Displacement sensor is non-contact (Contactless type), in addition to inductive (capacitive) or magnetic (Magnetic type such as Hall sensor) There are many options, but the signal processing method is different from the technology. (However, the photoelectric type is susceptible to contamination and is not suitable for use). The built-in components such as the signal processor 6 and the tire pressure display 7 can be assembled by anyone who has the ability to understand their physical phenomena and experience in circuit design, or they can be purchased and modified from related products. Which way it is obtained, and its simple structure, are subject to repeated packaging. ^ Not easy to accept, maintenance requirements are extremely minimal and extremely durable. Only autos are very safe and reliable vehicles. It is not recommended to assemble or modify them by yourself. • = The cost of a flat installation is low, and only a small amount of electricity can play the function of sensing, displaying and displaying tire pressure. Therefore, before the car leaves the factory, after installing the monitoring device of this Γ, it can almost be regarded as a once and for all equipment.
