MEMS陀螺仪的简要介绍(性能参数和使用)

MEMS陀螺仪的简要介绍(性能参数和使用)

MEMS陀螺仪的简要介绍(性能参数和使用)MEMS传感器市场浪潮可以从最早的汽车电子到近些年来的消费电子,和即将来到的物联网时代。

如今单一的传感器已不能满足人们对功能、智能的需要,像包括MEMS惯性传感器、MEMS环境传感器、MEMS光学传感器、甚至生物传感器等多种传感器数据融合将成为新时代传感器应用的趋势。

工欲善其事,必先利其器,这里就先以MEMS陀螺仪开始,简要介绍一下MEMS陀螺仪、主要性能参数和使用。

传统机械陀螺仪主要利用角动量守恒原理,即:对旋转的物体,它的转轴指向不会随着承载它的支架的旋转而变化。

MEMS陀螺仪主要利用科里奥利力(旋转物体在有径向运动时所受到的切向力)原理,公开的微机械陀螺仪均采用振动物体传感角速度的概念,利用振动来诱导和探测科里奥利力。

MEMS陀螺仪的核心是一个微加工机械单元,在设计上按照一个音叉机制共振运动,通过科里奥利力原理把角速率转换成一个特定感测结构的位移。

以一个单轴偏移(偏航,YAW)陀螺仪为例,通过图利探讨最简单的工作原理。

两个相同的质量块以方向相反的做水平震荡,如水平方向箭头所示。

当外部施加一个角速率,就会出现一个科氏力,力的方向垂直于质量运动方向,如垂直方向箭头所示。

产生的科氏力使感测质量发生位移,位移大小与所施加的角速率大小成正比。

因为感测器感测部分的动电极(转子)位于固定电极(定子)的侧边,上面的位移将会在定子和转子之间引起电容变化,因此,在陀螺仪输入部分施加的角速率被转化成一个专用电路可以检测的电子参数---电容量。

下图是一种MEMS陀螺仪的系统架构,,陀螺仪的讯号调节电路可以分为马达驱动和加速度计感测电路两个部分。

其中,马达驱动部分是透过静电引动方法,使驱动电路前后振动,为机械元件提供激励;而感测部分透过测量电容变化来测量科氏力在感测质量上产生的位移。

当然,MEMS陀螺仪还具有其它功能模块,比如自检功能电路,低功耗以及运动唤醒电路等等。

下面主要介绍MEMS陀螺仪的主要性能参数。

Increasing an individual’s quality of life via their intelligent home The hypothesis of this project is: can an individual’s quality of life be increased by integrating “intelligent technology” into their home environment. This hypothesis is very broad, and hence the researchers will investigate it with regard to various, potentially over-lapping, sub-sections of the population. In particular, the project will focus on sub-sections with health-care needs, because it is believed that these sub-sections will receive the greatest benefit from this enhanced approach to housing. Two research questions flow from this hypothesis: what are the health-care issues that could be improved via “intelligent housing”, and what are the technological issues needing to be sol ved to allow “intelligent housing” to be constructed? While a small number of initiatives exist, outside Canada, which claim to investigate this area, none has the global vision of this area. Work tends to be in small areas with only a limited idea of how the individual pieces contribute towards a greater goal. This project has a very strong sense of what it is trying to attempt, and believes that without this global direction the other initiatives will fail to address the large important issues described within various parts of this proposal, and that with the correct global direction the sum of the parts will produce much greater rewards than the individual components. This new field has many parallels with the field of business process engineering, where many products fail due to only considering a sub-set of the issues, typically the technology subset. Successful projects and implementations only started flow when people started to realize that a holistic approach was essential. This holistic requirement also applies to the field of “smart housing”; if we genuinely want it to have benefit to the community rather than just technological interest. Having said this, much of the work outlined below is extremely important and contains a great deal of novelty within their individual topics.Health-Care and Supportive housing:To date, there has been little coordinated research on how “smart house” technologies can assist frail seniors in remaining at home, and/or reduce the costs experienced by their informal caregivers. Thus, the purpose of the proposed research is to determine the usefulness of a variety of residential technologies in helping seniors maintain their independence and in helping caregivers sustain their caringactivities.The overall design of the research is to focus on two groups of seniors. The first is seniors who are being discharged from an acute care setting with the potential for reduced ability to remain independent. An example is seniors who have had hip replacement surgery. This group may benefit from technologies that would help them become adapted to their reduced mobility. The second is seniors who have a chronic health problem such as dementia and who are receiving assistance from an informal caregiver living at a distance. Informal caregivers living at a distance from the cared-for senior are at high risk of caregiver burnout. Monitoring the cared-for senior for health and safety is one of the important tasks done by such caregivers. Devices such as floor sensors (to determine whether the senior has fallen) and access controls to ensure safety from intruders or to indicate elopement by a senior with dementia could reduce caregiver time spent commuting to monitor the senior.For both samples, trials would consist of extended periods of residence within the ‘smart house’. Samples of seniors being discharged from acute care would be recruited from acute care hospitals. Samples of seniors being cared for by informal caregivers at a distance could be recruited through dementia diagnosis clinics or through request from caregivers for respite.Limited amounts of clinical and health service research has been conducted upon seniors (with complex health problems) in controlled environments such as that represented by the “smart house”. For exa mple, it is known that night vision of the aged is poor but there is very little information regarding the optimum level of lighting after wakening or for night activities. Falling is a major issue for older persons; and it results in injuries, disabilities and additional health care costs. For those with dementing illnesses, safety is the key issue during performance of the activities of daily living (ADL). It is vital for us to be able to monitor where patients would fall during ADL. Patients and caregivers activities would be monitored and data will be collected in the following conditions.Projects would concentrate on sub-populations, with a view to collecting scientific data about their conditions and the impact of technology upon their life styles. For example:Persons with stable chronic disability following a stroke and their caregivers: to research optimum models, types and location of various sensors for such patients (these patients may have neglect, hemiplegia, aphasia and judgment problems); to research pattern of movements during the ambulation, use of wheel chairs or canes on various type of floor material; to research caregivers support through e-health technology; to monitor frequencies and location of the falls; to evaluate the value of smart appliances for stroke patients and caregivers; to evaluate information and communication technology set up for Tele-homecare; to evaluate technology interface for Tele-homecare staff and clients; to evaluate the most effective way of lighting the various part of the house; to modify or develop new technology to enhance comfort and convenience of stroke patients and caregivers; to evaluate the value of surveillance systems in assisting caregivers.Persons with Alzheimer’s disease and their caregivers: to evaluate the effect of smart house (unfamiliar environment) on their ability to conduct self-care with and without prompting; to evaluate their ability to use unfamiliar equipment in the smart house; to evaluate and monitor persons with Alzheimer’s diseas e movement pattern; to evaluate and monitor falls or wandering; to evaluate the type and model of sensors to monitor patients; to evaluate the effect of wall color for patients and care givers; to evaluate the value of proper lighting.Technology - Ubiquitous Computing:The ubiquitous computing infrastructure is viewed as the backbone of the “intelligence” within the house. In common with all ubiquitous computing systems, the primary components with this system will be: the array of sensors, the communication infrastructure and the software control (based upon software agents) infrastructure. Again, it is considered essential that this topic is investigated holistically.Sensor design: The focus of research here will be development of (micro)-sensors and sensor arrays using smart materials, e.g. piezoelectric materials, magneto strictive materials and shape memory alloys (SMAs). In particular, SMAs are a class of smart materials that are attractive candidates for sensing and actuating applications primarily because of their extraordinarily high work output/volume ratiocompared to other smart materials. SMAs undergo a solid-solid phase transformation when subjected to an appropriate regime of mechanical and thermal load, resulting in a macroscopic change in dimensions and shape; this change is recoverable by reversing the thermo mechanical loading and is known as a one-way shape memory effect. Due to this material feature, SMAs can be used as both a sensor and an actuator.A very recent development is an effort to incorporate SMAs in micro-electromechanical systems (MEMS) so that these materials can be used as integral parts of micro-sensors and actuators.MEMS are an area of activity where some of the technology is mature enough for possible commercial applications to emerge. Some examples are micro-chemical analyzers, humidity and pressure sensors, MEMS for flow control, synthetic jet actuators and optical MEMS (for the next generation internet). Incorporating SMAs in MEMS is a relatively new effort in the research community; to the best of our knowledge, only one group (Prof. Greg Carman, Mechanical Engineering, University of California, Los Angeles) has successfully demonstrated the dynamic properties of SMA-based MEMS. Here, the focus will be to harness the sensing and actuation capabilities of smart materials to design and fabricate useful and economically viable micro-sensors and actuators.Communications: Construction and use of an “intelligent house” offers extensive opportunities to analyze and verify the operation of wireless and wired home-based communication services. While some of these are already widely explored, many of the issues have received little or no attention. It is proposed to investigate the following issues:Measurement of channel statistics in a residential environment: knowledge of the indoor wireless channel statistics is critical for enabling the design of efficient transmitters and receivers, as well as determining appropriate levels of signal power, data transfer rates, modulation techniques, and error control codes for the wireless links. Interference, channel distortion, and spectral limitations that arises as a result of equipment for the disabled (wheelchairs, IV stands, monitoring equipment, etc.) is of particular interest.Design, analysis, and verification of enhanced antennas for indoor wirelesscommunications. Indoor wireless communications present the need for compact and rugged antennas. New antenna designs, optimized for desired data rates, frequency of operation, and spatial requirements, could be considered.Verification and analysis of operation of indoor wireless networks: wireless networking standards for home automation have recently been commercialized. Integration of one or more of these systems into the smart house would provide the opportunity to verify the operation of these systems, examine their limitations, and determine whether the standards are over-designed to meet typical requirements.Determination of effective communications wiring plans for “smart homes.”: there exist performance/cost tradeoffs regarding wired and wireless infrastructure. Measurement and analysis of various wireless network configurations will allow for determination of appropriate network designs.Consideration of coordinating indoor communication systems with larger-scale communication systems: indoor wireless networks are local to the vicinity of the residence. There exist broader-scale networks, such as the cellular telephone network, fixed wireless networks, and satellite-based communication networks. The viability and usefulness of compatibility between these services for the purposes of health-care monitoring, the tracking of dementia patients, etc needs to be considered.Software Agents and their Engineering: An embedded-agent can be considered the equivalent of supplying a friendly expert with a product. Embedded-agents for Intelligent Buildings pose a number of challenges both at the level of the design methodology as well as the resulting detailed implementation. Projects in this area will include:Architectures for large-scale agent systems for human inhabited environment: successful deployment of agent technology in residential/extended care environments requires the design of new architectures for these systems. A suitable architecture should be simple and flexible to provide efficient agent operation in real time. At the same time, it should be hierarchical and rigid to allow enforcement of rules and restrictions ensuring safety of the inhabitants of the building system. These contradictory requirements have to be resolved by designing a new architecture that will be shared by all agents in the system.Robust Decision and Control Structures for Learning Agents: to achieve life-long learning abilities, the agents need to be equipped with powerful mechanisms for learning and adaptation. Isolated use of some traditional learning systems is not possible due to high-expected lifespan of these agents. We intend to develop hybrid learning systems combining several learning and representation techniques in an emergent fashion. Such systems will apply different approaches based on their own maturity and on the amount of change necessary to adapt to a new situation or learn new behaviors. To cope with high levels of non-determinism (from such sources as interaction with unpredictable human users), robust behaviors will be designed and implemented capable of dealing with different types of uncertainty (e.g. probabilistic and fuzzy uncertainty) using advanced techniques for sensory and data fusion, and inference mechanisms based on techniques of computational intelligence.Automatic modeling of real-world objects, including individual householders: The problems here are: “the locating and extracting” of information essential for representation of personality and habits of an individual; development of systems that “follow and adopt to” individual’s mood and behavior. The solutions, based on data mining and evolutionary techniques, will utilize: (1) clustering methods, classification tress and association discovery techniques for the classification and partition of important relationships among different attributes for various features belonging to an individual, this is an essential element in finding behavioral patterns of an individual; and (2) neuro-fuzzy and rule-based systems with learning and adaptation capabilities used to develop models of an individual’s characteristics, this is essential for estimation and prediction of potential activities and forward planning.Investigation of framework characteristics for ubiquitous computing: Consider distributed and internet-based systems, which perhaps have the most in common with ubiquitous computing, here again, the largest impact is not from specific software engineering processe s, but is from available software frameworks or ‘toolkits’, which allow the rapid construction and deployment of many of the systems in these areas. Hence, it is proposed that the construction of the ubiquitous computing infrastructure for the “smart house” should also be utilized as a software engineering study. Researchers would start by visiting the few genuine ubiquitous computing systems inexistence today, to try to build up an initial picture of the functionality of the framework. (This approach has obviously parallels with the approach of Gamma, Helm, Johnson and Vlissides deployed for their groundbreaking work on “design patterns”. Unfortunately, in comparison to their work, the sample size here will be extremely small, and hence, additional work will be required to produce reliable answers.) This initial framework will subsequently be used as the basis of the smart house’s software system. Undoubtedly, this initial framework will substantially evolve during the construction of the system, as the requirements of ubiquitous computing environment unfold. It is believed that such close involvement in the construction of a system is a necessary component in producing a truly useful and reliable artifact. By the end of the construction phase, it is expected to produce a stable framework, which can demonstrate that a large number of essential characteristics (or patterns) have been found for ubiquitous computing.Validation and Verification (V&V) issues for ubiquitous computing: it is hoped that the house will provide a test-bed for investigating validation and verification (V&V) issues for ubiquitous computing. The house will be used as an assessment vehicle to determine which, if any, V&V techniques, tools or approaches are useful within this environment. Further, it is planned to make this trial facility available to researchers worldwide to increase the use of this vehicle. In the long-term, it is expected that the facilities offered by this infrastructure will evolve into an internationally recognized “benchmarking” site for V&V activities in ubiquitous computing.Other technological areas:The project also plans to investigate a number of additional areas, such as lighting systems, security systems, heating, ventilation and air conditioning, etc. For example, with regard to energy efficiency, the project currently anticipates undertaking two studies:The Determination of the effectiveness of insulating shutters: Exterior insulating shutters over time are not effective because of sealing problems. Interior shutters are superior and could be used to help reduce heat losses. However, their movement and positioning needs appropriate control to prevent window breakage due to thermalshock. The initiation of an opening or closing cycle would be based on measured exterior light levels; current internal heating levels; current and expected use of the house by the current inhabitants, etc.A comparison of energy generation alternatives: The energy use patterns can easily be monitored by instrumenting each appliance. Natural gas and electricity are natural choices for the main energy supply. The conversion of the chemical energy in the fuel to heat space and warm water can be done by conventional means or by use of a total energy system such as a V olvo Penta system. With this system, the fuel is used to power a small internal combustion engine, which in turn drives a generator for electrical energy production. Waste heat from the coolant and the exhaust are used to heat water for domestic use and space heating. Excess electricity is fed back into the power grid or stored in batteries. At a future date, it is planned to substitute a fuel cell for the total energy system allowing for a direct comparison of the performance of two advanced systems.Intelligent architecture: user interface design to elicit knowledge modelsMuch of the difficulty in architectural design is in integrating and making explicit the knowledge of the many converging disciplines (engineering, sociology, ergonomic sand psychology, to name a few), the building requirements from many view points, and to model the complex system interactions. The many roles of the architect simply compound this. This paper describes a system currently under development—a 3Ddesign medium and intelligent analysis tool, to help elicit and make explicit these requirements. The building model is used to encapsulate information throughout the building lifecycle, from inception and master planning to construction and ‘lived-in’ use. From the tight relationship between m aterial behaviour of the model, function analysis and visual feedback, the aim is to help in the resolution of functional needs, so that the building meets not only the aims of the architect, but the needs of the inhabitants, users and environment.The Problem of Designing the Built Environment:It is often said that architecture is the mother of the arts since it embodies all the techniques of painting: line, colour, texture and tone, as well as those of sculpture: shape, volume, light and shadow, and the changing relative position of the viewer, andadds to these the way that people inhabit and move through its space to produce—at its best—a spectacle reminiscent of choreography or theatre. As with all the arts, architecture is subject to personal critical taste and yet architecture is also a public art, in that people are constrained to use it. In this it goes beyond the other arts and is called on to function, to modify the climate, provide shelter, and to subdivide and structure space into a pattern that somehow fits the needs of social groups or organizations and cultures. Whilst architecture may be commissioned in part as a cultural or aesthetic expression, it is almost always required to fulfill a comprehensive programme of social and environmental needs.This requirement to function gives rise to three related problems that characterize the design and use of the built environment. The first depends on the difference between explicit knowledge—that of which we are at least conscious and may even have a scientific or principled understanding—and implicit knowledge, which, like knowing your mother tongue, can be applied without thinking. The functional programmes buildings are required to fulfill are largely social, and are based on implicit rather than explicit bodies of knowledge. The knowledge we exploit when we use the built environment is almost entirely applied unconsciously. We don’t have to think about buildings or cities to use them; in fact, when we become aware of it the built environment is often held to have failed. Think of the need for yellow lines to help people find their way around the Barbican complex in the City of London, or the calls from tenants to ‘string up the architects’ when housing estates turn out to be social disasters.The second is a problem of complexity. The problem is that buildings need to function in so many different ways. They are spatial and social, they function in terms of thermal environment, light and acoustics, they use energy and affect people’s health, they need to be constructed and are made of physical components that can degrade and need to be maintained. On top of all this they have an aesthetic and cultural role, as well as being financial investments and playing an important role in the economy. Almost all of these factors are interactive—decisions taken for structural reasons have impacts on environment or cost—but are often relatively independent in terms of the domains ofknowledge that need to be applied. This gives rise to a complex design problem in which everything knocks on to everything else, and in which no single person has a grasp of all the domains of knowledge required for its resolution. Even when the knowledge that needs to be applied is relatively explicit—as for instance in structural calculations, or thoseconcerning thermal performance—the complex interactive nature of buildings creates a situation in which it is only through a team approach that design can be carried out, with all that this entails for problems of information transfer and breakdowns in understanding.The third is the problem of ‘briefing’. It is a characteristic of building projects that buildings tend not to be something that people buy ‘off-the-shelf’. Often the functional programme is not even explicit at the outset. One might characterise the process that actually takes place by saying that the design and the brief ‘co-evolve’. As a project moves from inception to full sp ecification both the requirements and the design become more and more concrete through an iterative process in which design of the physical form and the requirements that it is expected to fulfill both develop at once. Feasible designs are evaluated according to what they provide, and designers try to develop a design that matches the client’s requirements. Eventually, it is to be hoped, the two meet with the textual description of what is required and the physical description of the building that will provide it more or less tying together as the brief becomes a part of the contractual documentation that theclient signs up to.These three problems compound themselves in a number of ways. Since many of the core objectives of a client organization rest on implicit knowledge—the need for a building to foster communication and innovation amongst its workers for instance—it is all too easy for them to be lost to sight against the more explicitly stated requirements such as those concerned with cost, environmental performance or statutory regulations. The result is that some of the more important aspects of the functional programme can lose out to less important but better understood issues. This can be compounded by the approach that designers take in order to control themcomplexity of projects. All too often the temptation is to wait until the general layout of a building is ‘fixed’ before calling in the domain experts. The result is that functional design has to resort to retrofitting to resolve problems caused by the strategic plan.The Intelligent Architecture project is investigating the use of a single unified digital model of the building to help resolve these problems by bringing greater intelligence to bear at the earliest ‘form generating’ phase of the design process when the client’s requirements are still being specified and when both physical design and client expectations are most easily modified. The aim is to help narrow the gap between what clients hope to obtain and what they eventually receive from a building project.The strategy is simple. By capturing representations of the building as a physical and spatial system, and using these to bring domain knowledge to bear on a design at its earliest stages, it is hoped that some of the main conflicts that lead to sub- optimal designs can be avoided. By linking between textual schedules of requirements and the physical/spatial model it is intended to ease the reconciliation of the brief and the design, and help the two to co-evolve. By making available some of the latest ‘intelligent’ techniques for modelling spatial systems in the built environment, it is hoped to help put more of the implicit knowledge on an equal footing with explicit knowledge, and by using graphical feedback about functional outcomes where explicit knowledge exists, to bring these within the realm of intuitive application by designers.The Workbench:In order to do this, Intelligent Architecture has developed Pangea. Pangea has been designed as a general-purpose environment for intelligent 3D modelling—it does not pre-suppose a particular way of working, a particular design solution, or even a particular application domain. Several features make this possible.Worlds can be constructed from 3D and 2D primitives (including blocks, spheres, irregular prisms and deformable surfaces), which can represent real-world physical objects, or encapsulate some kind of abstract behaviour. The 3D editor provides a direct and simple interface for manipulating objects—to position, reshape, rotate andrework. All objects, both physical and abstract, have an internal state (defined by attributes), and behaviour, rules and constraints (in terms of a high-level-language ‘script’). Attributes can be added dynamically, making it possible for objects to change in nature, in response to new knowledge about them, or to a changing environment. Scripts are triggered by events, so that objects can respond and interact, as in the built environment, molecular systems, or fabric falling into folds on an irregular surface.Dynamic linking allows Pangea’s functionality to be extended to include standard ‘off-the-peg’ software tools —spreadsheets, statistical analysis applications, graphing packages and domain-specific analysis software, such as finite element analysis for air- flow modelling. The ‘intelligent toolkit’ includes neural networks [Koho89] [Wass89], genetic algorithms [Gold89] [Holl75] and other stochastic search techniques [KiDe95], together with a rule- based and fuzzy logic system [Zade84]. The intelligent tools are objects, just like the normal 3D primitives: they have 3D presence and can interact with other 3D objects. A natural consequence of this design is easy ‘hybridisability’ of techniques, widely considered as vital to the success of intelligent techniques in solving realistically complex problems [GoKh95]. This infrastructure of primitive forms, intelligent techniques and high-level language makes it possible to build applications to deal with a broad range of problems, from the generation of architectural form, spatial optimisation, object recognition and clustering, and inducing rules and patterns from raw data.Embedding Intelligence:Many consider that there is an inevitable trade-off between computers as a pure design medium, and computers with intelligence, ‘as a thinking machine’ [Rich94]. We propose here that it is possible to provide both these types of support, and allow the user to choose how best to use each, or not, according to the situation.It is essential that the creative role of the architect is preserved as he or she uses the work bench, that the architect as artist may draw manipulate the world as seen through the workbench as freely as they would when using a sheet of paper.

-------电容传感器结构相对简单和宜于加工。可以通过改变d、ε或A 来实现非线性(比如用d)和线性(比如用A)的位置-电容转换。 ------电容传感器的最大优点是其温度系数低(只要极间材料是温度系 数低的介电质,比如空气或者真空)。根据文献,空气介电常数的温 度常数在1atm20℃时约为2ppm/ ℃(干燥), 到7ppm/ ℃(最潮湿)。但 是空气介电常数对于气压很敏感,约为100ppm/atm。如果极板间是 压力恒定的空气(或真空),起支配作用的影响是结构热变形不平衡 (通常也很小)。 -------另外一个优点是测量是非接触的。
半导体材料,特别是Ge和Si,作为机械量-电学量转换器利用起源于 1957年。在此以前C.S.Smith发表了Ge和Si的压阻系数比其它材料高的结 果。F.P.Burns用两块Si薄片制成了声音传感器,W.P.Mason等人几乎在 同时发表了更实用化的同种器件。二者是压阻传感的开始。 这之后,随着半导体材料加工技术的快速发展,材料变得更容易获得。 1960年左右丰田理研开发出了十分实用的半导体应变传感器,同 时,W.P.Wason等人制作了细长的Si传感器,可以贴在弹性体上作为载荷计 使用。1961和1962年的Instrument Society of America大会上半导体应 变传感器相关的报告很多。在此基础上,MicroSystem、Baidwin-LimaHamiton、和Kulite-Bytrex公司都先后推出了半导体应变计商品。另外 一些工业化生产的微传感器产品,包括在石英上制作的霍尔效应(Hall Effect)探头、加速度计、力传感器以及化学传感器等等。 可以用微系统技术开发的微型传感器种类很多,本课程无法全部介绍。 所以我们只能从基本的传感原理讨论入手,然后从一些典型微传感器结构 来看这些原理是如何应用的。

惯性传感器的介绍

惯性传感器的介绍

惯性传感器介绍构成惯性传感器包括加速度计(或加速度传感计)和角速度传感器(陀螺)以及它们的单、双、三轴组合IMU(惯性测量单元),AHRS(包括磁传感器的姿态参考系统)。

MEMS加速度计是利用传感质量的惯性力测量的传感器,通常由标准质量块(传感元件)和检测电路组成。

IMU主要由三个MEMS加速度传感器及三个陀螺和解算电路组成。

分类惯性传感器分为两大类:一类是角速率陀螺;另一类是线加速度计。

角速率陀螺又分为:机械式干式﹑液浮﹑半液浮﹑气浮角速率陀螺;挠性角速率陀螺;MEMS硅﹑石英角速率陀螺(含半球谐振角速率陀螺等);光纤角速率陀螺;激光角速率陀螺等。

线加速度计又分为:机械式线加速度计;挠性线加速度计;MEMS硅﹑石英线加速度计(含压阻﹑压电线加速度计);石英挠性线加速度计等。

惯性传感器作用原理(1).科里奥利(Coriolis)原理:也称科氏效应(科氏力正比于输入角速率)。

该原理适用于机械式干式﹑液浮﹑半液浮﹑气浮角速率陀螺;挠性角速率陀螺;MEMS硅﹑石英角速率陀螺(含半球谐振角速率陀螺)等。

Coriolis法国物理学家(1792年~1843年)。

(2).萨格纳(Sagnac)原理:也称萨氏效应(相位差正比于输入角速率)。

该原理适用于光纤角速率陀螺;激光角速率陀螺等。

Sagnac法国物理学家(1869年~1926年),居里夫妇的朋友。

1913年发明萨氏效应。

术语1. 角速率陀螺术语(1).测量范围(°/ S)Measurement Range也称量程。

指陀螺仪能测量正、反方向角速率的额定值范围。

在此额定值范围内,陀螺仪刻度因数非线性满足规定要求。

(2).刻度因数(mV /°/ S)Scale Factor (Sensitivity)也称刻度因子、标度因数、梯度、灵敏度。

指陀螺仪输出量与输入角速率的比值。

该比值是根据整个输入角速率范围内测得的输入、输出数据,通过最小二乘法拟合求出的直线的斜率。
