Description

200821553 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種感測器,特別是一種傾斜及振動感測 器。 【先前技術】 傾斜及振動感測器的使用範圍相當廣泛,尤其是目前曰 益注重的生活安全性提昇,及無人自動化控制機械上,特 別是在廣大的汽車市場應用,透過在車輛上裝置些許感測 器,進行即時的型態偵測,當超過設計限度即時的自動型 態修正或者發出警報,這樣的機制不論是在家用汽車的安 全提升或者產業用機械操作安全甚至是汽車防盜上都有相 當的幫助。 目前習知之傾斜及振動感測器大致可以分成三大類,其 分別使用固體、液體及氣體作為感測的變化源,分述如 下。 第一、固體式:傳統上是以鐘擺結構結合電阻計、電位 計或編碼器(如文獻[Hisao kato, Masahiko kojima; "Photoelectric Inclination sensor and Its Application to the Measurement of shapes of 3-D objects”; IEEE transaction on instrumentation and measurement Vol. 40. NO.6 December 1991·]所揭示)來達成感測的目標,缺點是體積太大難以微 小化,由於較大的質量所以也使得達到穩定態時間拉長, 降低了偵測速度。 第二、液體式:在腔體裡封進適量的流體,配合上導線 115209.doc 200821553 或電極,偵測導電度變化、平板電極間的電容變化(如文 獻[D. Benz,T. Botzelmann,H. K"uck,D. Warkentin; ’On low cost inclination sensors made from selectivelymetallized polymer11; Sensors and Actuators A 123-124 (2005) 18-22] 所揭示)、或者是偵測熱力學上的變化量來達成目標,這 種方法相較於固體式擁有比較小的體積,但是流體會有黏 滯性以及對於封裝的腔體材料有不同的吸附能力,所以流 體要擁有一定的質量才能克服上述的影響,所以也使得這 種類型設計有體積難以再縮小的缺點。加上流體如果封裝 不良會有蒸發乾涸的情況,讓長期使用的穩定性受到考 驗,採取量測電容變化作為偵測方式也相對上易受到環境 因素影響電容之輸出。此外,此種型式設計其偵測範圍通 常界於正負90度間,無法進行大角度之連續量測。 第三、氣體式:絕大部分是藉由熱電阻與熱電偶之間熱 力學平衡關係來達成偵測,是目前已知比較可靠且擁有比 較小體積的設計,但微導線以及電熱器設計需使用到較昂 貴的矽為材料及較昂貴的微影製程,如文獻[S.

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a sensor, and more particularly to a tilt and vibration sensor. [Prior Art] Tilt and vibration sensors are used in a wide range of applications, especially at the current level of life safety improvement, and on unmanned automated control machinery, especially in the automotive market, by installing a little on the vehicle. Sensors for instant type detection, automatic type corrections or alarms that exceed the design limits, such mechanisms are safe for home use, industrial safety, or even car burglary. Quite helpful. Conventional tilt and vibration sensors can be broadly classified into three broad categories, using solids, liquids, and gases as sources of sensing change, respectively, as described below. First, solid type: traditionally a pendulum structure combined with a resistance meter, potentiometer or encoder (such as the literature [Hisao kato, Masahiko kojima; " Photoelectric Inclination sensor and Its Application to the Measurement of shapes of 3-D objects" ; IEEE transaction on instrumentation and measurement Vol. 40. NO.6 December 1991·]) to achieve the goal of sensing, the disadvantage is that the volume is too large to be miniaturized, due to the larger quality, it also makes the steady state time pull Long, reduce the detection speed. Second, liquid type: seal the appropriate amount of fluid in the cavity, with the wire 115209.doc 200821553 or electrode, detect the change of conductivity, capacitance change between the plate electrodes (such as the literature [ D. Benz, T. Botzelmann, H. K"uck, D. Warkentin; 'On low cost inclination sensors made from selective metallized polymer11; Sensors and Actuators A 123-124 (2005) 18-22] Measuring the amount of change in thermodynamics to achieve the goal, this method has a smaller volume than the solid type, but the fluid will stick Sexuality and different adsorption capacity for the encapsulated cavity material, so the fluid must have a certain quality to overcome the above effects, so this type of design has the disadvantage that the volume is difficult to shrink again. The evaporative drying condition is used to test the stability of long-term use. The measurement of capacitance change as a detection method is also relatively easy to be affected by environmental factors. In addition, the detection range of this type design is usually between plus and minus 90. Between the degrees, continuous measurement at large angles is not possible. Third, gas type: most of them are detected by the thermodynamic equilibrium relationship between thermistor and the thermocouple, which is known to be relatively reliable and has a relatively small volume. The design, but the micro-wire and electric heater design requires the use of more expensive materials and more expensive lithography processes, such as the literature [S. Billat, H. Glosh, Μ · Kunze, F. Hedrich, J. Hedrich, J. Frech, J. Auber, H. Sandmaier, W. Wimmer, W. Lang; ''Micromachined inclinometer with high sensitivity and very good stabilit y"; Sensors and Actuators A 97-98 (2002) 125-130]. In addition, the literature [R. Olaru, DD Dragoi; ''Inductive tilt sensor with magnets and magnetic fluid 1*; Sensors and Actuators A 120 (2005) 424-428] disclosed in combination with magnets and magnetic fluids 115209.doc The sensor of 200821553 also has the function of sensing the inclination, but it has the disadvantages of large volume and small sensing angle. [Hisao kato, Masahiko kojima; ''Photoelectric Inclination sensor and Its Application to the Measurement of shapes of 3-D objects”; IEEE transaction on instrumentation and measurement Vol. 40 .NO.6 December 1991.] Photoelectric components are used to form the sensor, but the sensitivity is affected by the fluidity of the fluid. The three-dimensional structure design can achieve two-dimensional detection but the measurement angle is relatively small, and the expensive photodetector is used. In order to greatly increase the cost, it is difficult to achieve a large number of targets for mass production. Therefore, it is necessary to provide an innovative and progressive tilt and vibration sensor to solve the above problems. [Summary] The main object of the present invention is A tilt and vibration sensor includes a body, a first circuit, a second circuit, and a signal transmitting component.

When the signal transmitting component 47 is connected to the first circuit 45, the _ electrode 452 and the second electrode 462 of the second circuit 46, it is known from the voltage division law that when the resistor When the value changes, the measured voltage value will also follow the change. Thereby, the voltage division difference generated by the signal transmission element 47 at different positions can also achieve the measurement purpose. Referring to Fig. 5, a third embodiment of the tilting and vibration sensor of the present invention is shown. This figure is the curve of the inclination and vibration (the detector 4 is rotated at a fixed speed of 1/8 RPS (Revoluti〇ns Per Second), and the angle and voltage change obtained by the rotation of more than 360 degrees are obtained from the angle of the figure. The relationship between the voltages can be estimated that the tilt and vibration sensor 4 can have a measurement range of about 320 degrees, and the voltage and angle exhibit a highly linear relationship within this range. Referring to Figure 6, the tilt and vibration of the present invention are shown. The third embodiment of the sensor is in the angle-voltage diagram of the plus or minus 140 degree interval, wherein □ represents the curve of the forward direction, and ▲ represents the curve of the reverse direction. This figure is the tilt and vibration sense G detector 4 The fixed speed of /8RPS rotates in the forward direction. After the rotation of 14 degrees and then reverses the degree of 28G to minus 14G, the curve of the angle and the change of money is shown by the relationship between the angle and the voltage in the figure. Under the change of the angle of the stroke, the relationship between the angle and the voltage value changes fairly linearly, and the curve of the forward rotation reversal almost coincides, which means that the tilt and vibration sensor 4 has a fairly good reproducibility. The third embodiment of the tilting and vibration sensor of the present invention is shown as a time-voltage variation diagram with a degree of rotation of 0.9 degrees, wherein the solid line represents the original value curve, and the broken line represents the average value of the signal after the signal processing 115209. Doc -14- 200821553 r line. This figure is a time-voltage variation curve obtained by giving the tilt and vibration sensor 4 a single 9·9 degree step rotation, in which each rotation step The stagnation time is 2 seconds, and it is reversed after the third step. It can be seen from the figure that the voltage change of each step is about 2〇mV, and the variation of each step is quite stable, which means The tilting and vibration sensor 4 has good sensitivity under this rotation resolution and can be measured to be lower than the change of the angle k. In addition, the tilt and vibration sensor 4r are at the same angular position by the positive reversal. Having a close voltage level, representing that the surface friction of the tilt and vibration sensor 4 at this small angular movement has not significantly affected the performance of the tilt and vibration sensor 4, and also has good sensitivity and reproducibility. Participation Figure 8 is a timing-voltage diagram showing the third embodiment of the tilting and vibration sensor of the present invention rotated at different angular velocities, wherein x represents a curve at an angular velocity of 0 = 1/32 RPS, and the slope thereof is 0·0022; The curve representing the angular velocity ω = 1/16RPS has a slope of 0·0045; ▲ represents the angular velocity ω I =1/8RPS, the slope of the curve is 0.009; ◊ represents the angular velocity ω = 1/4RPS curve, the slope 〇·〇ΐ69 ; △ represents the curve of the angular velocity ω = 1/2RPS, the slope of which is 0·0319; the curve representing the angular velocity ω = 1RPS, the slope of which is 〇·〇547. Taking 1/8 RPS (the curve represented by ▲) as an example, in theory, the tilt and vibration sensor 4 rotates at a speed of i/8 rps for 500 milliseconds (ms), and its rotation angle should be 22.5 degrees, which is calculated by the previous one. The voltage change per degree is estimated to be about 20 mV, and the voltage change at this corner should be 450 mV. Compared with the curve of 1/8 RPS in Fig. 8, the actual voltage change is 445 mV (i.e., 6 V - 5.555 V), which are quite close. Therefore, 115209.doc -15- 200821553 estimates that at 1/16 RPS (the curve represented by 〇), the voltage change should be half of 1/8PRS when the corner is halved, and the slope development should be 1/2. , this result is consistent with that shown in Figure 8. A comparison of the curves below 1/8 RPS shown in Figure 8 is consistent with the estimate. In addition, at a speed higher than 1/8 RPS, the slope of the voltage change begins to be lower than the estimated value of ten, which represents a situation in which the tilting and vibration sensor 4 operates at this speed, that is, the signal transmitting element 47 The moving speed will be smaller than the overall tilting and the rotational speed of the vibration sensor 4, so the amount of voltage change that coincides with the theoretical estimation cannot be generated. The reason is that the signal transmission component 47 and the body 41 are frictionally caused by the signal transmission. The movement speed of the element 47 is delayed. In summary, it can be known that the tilt and vibration sensor 4 can have good operational performance at an angular rate of change lower than 1/8 RPS, and the voltage-angle change will be linear. The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the scope of the present invention. The scope of the invention should be as set forth in the appended claims.
