外文翻译原文和译文基于电阻应变式称重传感器的高精度和低容量电子秤开发
外文文献翻译译稿1基于电阻应变式称重传感器的高精度和低容量电子秤开发Baoxiang He,Guirong Lu ,Kaibin Chu ,Guoqiang Ma摘要：基于称重传感器的应变计优化设计中除了一些先进的稳定技术比如温度的影响之外，静态超载和计算机模式识别（CRT）技术也被用来进行动态模拟与分析。
这种多谐振荡的压力释放方法是在生产中创造性的使用了压力传感器，由于这种技术，量程30G的压力传感器才能做到高精度，高稳定性。
由于使用了这种压力传感器，使得基于传感器的电子秤拥有300,00种分类和小于0.2mg的精度。
这种压力传感器的量程和精度远远高于市场上的同类产品，而其价格却远低于电磁压力传感器。
因此，这种压力传感器的商业前景是十分广阔的。
关键词：设计；电阻应变式称重传感器；精度；电子秤1.介绍众所周知，压力传感器的精度是决定一个的电子秤精度的关键。
目前，用于高精度称重的传感器主要是电磁平衡式称重传感器。
低成本电阻应变式称重传感器仅能用于使低精度的称量。
主要影响精度应变式称重传感器的误差是蠕变和温度漂移，特别是对于低负荷的传感器来说。
一般来说，高精度传感器的负载能力最低是300克。
称重传感器的最大分配平衡只有50K，最小分辨率是不小于0.01克。
总而言之，对于超低容量称重传感器来说设计和制造技术是很难被应用到敏感的称重传感器的加工和生产中的。
因此很难做出足够好的高精度平衡的称重传感器。
使得低量程和高精度的传感器始终是全世界的热门话题。
本文将分析应力释放及补偿技术，探索低量程高精度应变式称重传感器的制造技术。
2．原理与方法A. 残余应力的释放制作压力传感器主要部件的材料是铝棒。
为了获得更好的综合性能，铝条会在挤压后进行淬火。
由于淬火的残余应力不能被自然老化而得到充分释放，此外，机械加工和固化过程中也会造成很大的残余应力，特别是对于超低容量称重传感器来说，如果这个压力不及时释放，可能就会在压力传感器被测试或者是最终使用的时候释放出来。

Currently, electronic scales used in commercial sales have been quite common, but all kinds of electronic scales are widely used in the market, there are significant limitations. These electronic scales large volume, high cost, need for frequency AC power supply, and can not carry. Popular portableelectronic weighing scales on the market, or they use a rod to the spring compression, tensile deformation of the spring balance to achieve, such as metering, measurement error is large, more than once spring elastic limit, it will generate a lot of errors, as well as damage to the rod type scales are currently going out of the metering equipment, therefore, a miniaturized, can be replaced in the future development of universal rod scales electronic scales by the people attach great importance to design a lightweight, easy to carry, accurate measurement, intuitive readings civilian electronic scales imminent.This product is fully electronic circuit design, fully taking into account the advantages of various types of electronic scales, and small and portable, measurement error is small (1%), reliable / low prices on the civilian market has good prospects for use.1 System PrinciplesPortable electronic scale system shown( Figure 1), which consists of sensors, amplifiers, range conversion circuit, A / D converter and a display / power supply circuit and the like.Strain gauge sensor element consisting of a resistor, the weighing weak signal, the precision of the differential amplifier, two stages (0~2Kg, 2~10Kg) automatic conversion range, the A/D converter, said amplified re-converted into an analog signal to a digital liquid crystal display (LCD) display, the processing circuit power supply voltage into the battery power supply voltage level required for the type of each unit circuit.2 load cell selection and designIn the electronic scale system , the sensor is the most critical component is also part of the design of electronic scales difficult to deal with , its performance directlydetermines the accuracy of electronic scales . Small -scale load cell structure , type and more categories . In order to make the load cell has good linearity , strong input sensitivity and strong resistance to lateral load force , we have adopted a two-hole parallel beam load cell [1] ( Figure 2 ),as the use of domestic hard aluminum alloy LY12 elastomer material, the elastic hysteresis and creep is small, the small -scale load cell, the storage of this material is larger than W, elastic modulus is small (about 1 / 3 of steel), the manufacture of small the load cell weighing scale , and the ideal material.Working principle of the sensor is : When the sensor is subjected to external loads prole of the upper and lower beams parallel elastomer elastic deformation / paste in a parallel beam of four strain gauges R1~ R4 consists of bridge output voltage is generated with linearized external load increment p , p can know the size of the external load.Size of the sensor according to the maximum range of the elastic element may be primarily determined detection point ( peak stress ) section thickness h1,, to determine the form and size of the opening , the sensor sensitivity is generally require (1.5 ~ 2) mV / V range, the full-bridge The output voltage U 0.As 0CC U S U ε=,Where: S-strain gauge sensitivity factor;U C C - -for the bridge voltageε-Detection Point (strain gauge affixed at) strain,S U U CC /)/(0=εAlso 1/P M E W ε= ,Where: Mp-detection point bending moment;E -modulus of elasticity of the material;W1-detection point flexural modulus; .)6/(211bh l W =Beacuse ),2/(:)2/(:max L l M M P = (Similar triangles);So ,4/)4/)(/(pl pL L l M P -=Where: b -elastic element width;h1-sectional thickness detection point ;Mmax = pL/4- maximum bending moments at both ends of the elastic element ; p-Maximum weight;l-double hole center distance;L-length of elastomersCan push 164pl h Ebε= Open hole diameter 12h φα=-，2()/2h L l φ=--The stiffness ratio αL h h K 312)(= . This value can be used as calibration values estimated elastic stiffness is adequate. Size elastomer determined according to the above principles, its processing byconventional technology standards, through the heat out of the library , the opening line cutting , grinding and other processes required by conventional patch3 amplifier circuit design processing several problems(1) Power : This e- weighed 2 on the 5th ordinary zinc-manganese batteries (3V) or rechargeable battery (2.4V) power supply. For each level of the supply voltage circuit for this is not enough , so the choice of switching to Boost Regulator Manifold TL499A for power conversion ( Figure 3 ).The output voltage of the regulator TL499A range of up to 2.9 ~ 30V, output current of 100mA, the required input voltage range of 1.1 ~ 10V. TL499A the battery voltage up to 15V, 7.5V and then get a symmetrical voltage output through the op amp. (2) Reduce the influence of the equivalent offset voltage measurement accuracy ; bridge output signal is superimposed on a high voltage DC supply mold weak signal , you should first ensure that the power bridge to get a high degree of stability , constant current bridge uses circuitry as shown in ( 4 ) below.By the A1, R5, R6, R1 constitute a constant current source circuit for providing a high degree of stability bridge power circuit . R1-R4 constituting the detection resistance strain gauge bridge force due to the action of the force to deform the elastic body , leaving a corresponding change in strain gauge resistance , thereby weak bridge output voltage signal proportional to the force by the elastic body , Rp is zero potentiometer to adjust the bridge output to zero. A2-A5 and peripheral components of the differential amplifier . The circuit has an input impedance (300-500mΏ) high , high common mode rejection ratio (110DB). Input offset voltage (20uv) and offset voltage drift (0.25-10uv / ℃) small features, ideal for the bridge amplifier circuit form . Circuit is divided into two , the first stage consists of A2, A3 , thereby to improve the input impedance of the amplifier circuit , the second stage by the A4, A5 constitute a differential amplifier , seeking an exact match to A4 external resistor , while lower gain circuit has guaranteed small offset voltage , Rw number tune the gain of the amplifier.(3) Achieve scale transformation , the electronic scale range is divided into two ranges , the first range 0-2Kg, second range 2-10Kg, automatic conversion range fromthe circuit ( Figure 5 ).A/D conversion and the reality circuit ICL7106 completed by the manifold, range conversion by changing the reference voltage VREF 7106 implementation. Weighing comparator circuit compares the output signal of the differential amplifier composed by A6 , when the weighing scale at 0 - 1999g range, the signal is small , the comparator does not move from Rp1 adjusted reference voltage through analog switches SW1, plus to VREF end 7106 ; when weighing more than 1999g, comparator A6 flip RP2 obtained by the reference voltage signal via the analog switch SW2 to 7106 ; simultaneously output A6 control the position of the decimal point is lit LCD display.4 Test ResultsBy actual measurement , the electronic scale technical indicators are as follows : Accuracy degree level : 3 Maximum weighing : 10kgMinimum scale value : Range :0 - 1999g time error : ≤1%Range :1.999-10kg when drift : <0.1% / ℃Weight : ≤400g volume: about 110mmx80mmx35mm5 ConclusionsRenamed some of the performance characteristics of some failings , one of which is the high price , after accounting cost about 120 yuan ; Furthermore high linearity error ; function is still lacking, such as tare function , computing functions. These need to be addressed in a future circuit improvements . As electronic scales small, easy to carry , such as to further reduce costs in the civilian market will have good prospects for use A/D conversion and the reality circuit ICL7106 completed by the manifold , range conversion by changing the reference voltage VREF 7106 implementation.
