3自动控制技术在精准农业中的应用。
Application of 3 automatic control technology in precision agriculture.
现在农业正在向着精准农业发展,精准农业是在信息技术的支持下根据空间变异,利用GPS定位,按时按量的实行农业操作和管理。精准农业主要是根据农作物的生存土壤状况,调节对农作物的投入,他一方面需要查清田地内的土壤性状和生产力空间的变异,一方面确定农作物的生产目标,进行定位的科学管理,最优化的方案调动土壤生产能力,用最少的的投入达到最大的收益化,而且还可以改善环境,高效地利用各类农业资源美国竹柳,这样可以取的经济效益和环境效益的双重收入。

精准农业是有十多个复杂的系统组成的,即网络化管理系统,农业专家系统,农田地理信息系统等组成,其核心是建立一个健全完善的农田地理信息系统。可以说是现代信息技术和农业结合的一种新型农业。精准农业强调的是农业收获效益,而不是过分强调的高产。精准农业将农业带入了信息化和数字时代,是农业发展的重要方向。
Precision agriculture is composed of more than 10 complex system, namely the network management system, agricultural expert system, composed of Farmland Geographic information system, its core is the establishment of a perfect Farmland Geographic Information system. Can be said to be a new type of agriculture and agriculture with modern information technology. Emphasis on precision agriculture is agricultural economic benefits, but not too much emphasis on the high yield. Precision agriculture agriculture into information and digital era, is an important direction of agricultural development.
传统农业的发展在很大程度上依赖于生物遗传育种技术,以及化肥、农药、矿物能源、机械动力等投入的大量增加而实现。由于化学物质的过量投入引起生态环境和农产品质量下降,高能耗的管理方式导致农业生产效益低下,资源日显短缺,在农产品国际市场竞争日趋激烈的时代,这种管理模式显然不能适应农业持续发展的需要。
The development of traditional agriculture largely relies on the technology of biological genetic breeding, as well as a large number of chemical fertilizer, pesticide, mineral energy, mechanical power and the increase of input and realization. Due to excessive inputs of chemical substances cause the decline of ecological environment and the quality of agricultural products, high energy consumption management mode leads to the agricultural production efficiency is low, resources shortage, in the competition of agricultural products in the international market increasingly competitive era, this kind of management pattern obviously cannot meet the need of agricultural sustainable development.
4 农业机械自动化的必要性
The necessity of 4 agricultural machinery automation
4.1 解决农村劳力不足问题
To solve the problem of the shortage of labor force in rural areas 4.1
当今社会经济全球化,信息透明化,社会变的越来越精彩,对人们的吸引力也越来越大,令
无数的农村的青壮年向往,造成大量的农村劳动力离开农业生产。农村有知识有文化的大学生由于在学习的过程中就被城市生活吸引也偏爱经济发达地区和城市的机关或企业。很少有人回到农村和偏僻的山村。这就造成了我国基层农业劳动力的减少和农业人才的流失。此外,我国人口老龄化问题也日益严重,一些地区相继进入老龄化社会,这些问题导致了农村人口结构的变化,农村剩余大量的老弱病残等人,上述这些问题导致农村人口结构的变化,从而将在更大程度上产生对农业机械自动化的需求,实现农业土工膜生产的自动化是必然的。
In today's economic globalization, transparency of information, the society becomes more and more exciting, attractive force to people is also more and more big, make countless rural young people aspire to, resulting in a large number of rural labor out of agriculture production. Rural knowledge students because in the process of learning is also prefer city life attract economically developed areas and the city authorities or enterprises. Few people back to the village of rural and remote. This caused the agricultural labor of our country agriculture is reduced and the loss of talent. In addition, the problem of aging population in China is becoming more and more serious, some areas have entered the aging society, these problems led to the change in rural population, rural surplus large Laoruobingcan et al., these problems lead to the change of the rural population structure, which will produce to the automation of agricultural machinery demand to a greater extent, realize automation of agricultural production is inevitable.
4.2 社会进步的需求
4.2, the social progress demands
随着社会的进步,科技的发展,人们的观念正逐渐发生着变化,现在人们已不再满足于温饱问题,而是对生活提出了更高的要求,向着更营养,高品质的农业产品。从事农业的劳动者也对劳动生产率和和劳动的舒适性提出更高的要求。伴随着全球一体化,中国加入WTO,农产品也面临着开放进口和全球的市场竞争压力双重压力,在农业生产中只有提高劳动生产率,降低生产成本,提高产品质量才能在竞争中立于不败之地复合土工膜。从这些新的需求看农业生产必向着高效,高精度的机械自动化发展。
Along with the progress of the society, the development of science and technology, people's concept is gradually changing, now people are no longer satisfied with the problem of food and clothing, but also put forward higher requirements for life, more nutrition, agricultural product quality. Agricultural workers also put forward higher requirements on labor productivity and labor comfort. Along with the global integration, China's accession to the WTO, agricultural products
are facing market competition pressure to open the import and global, only improve labor productivity in agricultural production, reduce production costs, improve product quality to remain invincible in the competition. Agricultural production will be toward high efficiency from these new requirements, the development of high precision machinery automation.

英文翻译 机械设计 一台完整机器的设计是一个复杂的过程。机械设计是一项创造性的工作。设计工程师不仅在工作上要有创造性，还必须在机械制图、运动学、工程材料、材料力学和机械制造工艺学等方面具有深厚的基础知识。 Machine Design The complete design of a machine is a complex process. The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manufacture technology has the deep elementary knowledge. 任何产品在设计时第一步就是选择产品每个部分的构成材料。许多的材料被今天的设计师所使用。对产品的功能，它的外观、材料的成本、制造的成本作出必要的选择是十分重要的。对材料的特性必须事先作出仔细的评估。 One of the first steps in the design of any product is to select the material from which each part is to be made. Numerous materials are available to today's designers. The function of the product, its appearance, the cost of the material, and the cost of fabrication are important in making a selection. A careful evaluation of the properties of a. material must be made prior to any calculations. 仔细精确的计算是必要的，以确保设计的有效性。在任何失败的情况下，最好知道在最初设计中有有缺陷的部件。计算（图纸尺寸）检查是非常重要的。一个小数点的位置放错，就可以导致一个本可以完成的项目失败。设计工作的各个方面都应该检查和复查。 Careful calculations are necessary to ensure the validity of a design. In case of any part failures, it is desirable to know what was done in originally designing the defective components. The checking of calculations (and drawing dimensions) is of utmost importance. The misplacement of one decimal point can ruin an otherwise acceptable project. All aspects of design work should be checked and rechecked. 计算机是一种工具，它能够帮助机械设计师减轻繁琐的计算，并对现有数据提供进一步的分析。互动系统基于计算机的能力，已经使计算机辅助设计（CAD）和计算机辅助制造（CAM）成为了可能。心理学家经常谈论如何使人们适应他们所操作的机器。设计人员的基本职责是努力使机器来适应人们。这并不是一项容易的工作，因为实际上并不存在着一个对所有人来说都是最优的操作范围和操作

外文翻译 英文原文 Belt Conveying Systems Development of driving system Among the methods of material conveying employed，belt conveyors play a very important part in the reliable carrying of material over long distances at competitive cost．Conveyor systems have become larger and more complex and drive systems have also been going through a process of evolution and will continue to do so．Nowadays，bigger belts require more power and have brought the need for larger individual drives as well as multiple drives such as 3 drives of 750 kW for one belt(this is the case for the conveyor drives in Chengzhuang Mine)．The ability to control drive acceleration torque is critical to belt conveyors’ performance．An efficient drive system should be able to provide smooth，soft starts while maintaining belt tensions within the specified safe limits．For load sharing on multiple drives．torque and speed control are also important consideratio ns in the drive system’s design. Due to the advances in conveyor drive control technology，at present many more reliable．Cost-effective and performance-driven conveyor drive systems cov ering a wide range of power are available for customers’ choices[1]. 1 Analysis on conveyor drive technologies 1．1 Direct drives Full-voltage starters．With a full-voltage starter design，the conveyor head shaft is direct-coupled to the motor through the gear drive．Direct full-voltage starters are adequate for relatively low-power, simple-profile conveyors．With direct fu11-voltage starters．no control is provided for various conveyor loads and．depending on the ratio between fu11- and no-1oad power requirements，empty starting times can be three or four times faster than full load．The maintenance-free starting system is simple，low-cost and very reliable．However, they cannot control starting torque and maximum stall torque；therefore．they are
Ceramics and Glasses 陶瓷和玻璃 A ceramic is often broadly defined as any inorganic nonmetallic material． By this definition, ceramic materials would also include glasses; however, many materials scientists add the stipulation that “ceramic” must also be crystalline. 陶瓷通常被概括地定义为无机的非金属材料。照此定义，陶瓷材料也应包括玻璃；然而许多材料科学家添加了“陶瓷”必须同时是晶体物组成的约定。 A glass is an inorganic nonmetallic material that does not have a crystalline structure. Such materials are said to be amorphous. 玻璃是没有晶体状结构的无机非金属材料。这种材料被称为非结晶质材料。Properties of Ceramics and Glasses Some of the useful properties of ceramics and glasses include high melting temperature, low density, high strength, stiffness, hardness, wear resistance, and corrosion resistance. 陶瓷和玻璃的特性 高熔点、低密度、高强度、高刚度、高硬度、高耐磨性和抗腐蚀性是陶瓷和玻璃的一些有用特性。 Many ceramics are good electrical and thermal insulators. Some ceramics have special properties: some ceramics are magnetic materials; some are piezoelectric materials; and a few special ceramics are superconductors at very low temperatures. Ceramics and glasses have one major drawback: they are brittle. 许多陶瓷都是电和热的良绝缘体。某些陶瓷还具有一些特殊性能：有些是磁性材料，有些是压电材料，还有些特殊陶瓷在极低温度下是超导体。陶瓷和玻璃都有一个主要的缺点：它们容易破碎。 Ceramics are not typically formed from the melt. This is because most ceramics will crack extensively (i.e. form a powder) upon cooling from the liquid state. 陶瓷一般不是由熔化形成的。因为大多数陶瓷在从液态冷却时将会完全破碎(即形成粉末)。 Hence, all the simple and efficient manufacturing techniques used for glass production such as casting and blowing, which involve the molten state, cannot be used for the production of crystalline ceramics. Instead, “sintering” or “firing” is the process typically used. 因此，所有用于玻璃生产的简单有效的—诸如浇铸和吹制这些涉及熔化的技术都不能用于由晶体物组成的陶瓷的生产。作为替代，一般采用“烧结”或“焙烧”工艺。 In sintering, ceramic powders are processed into compacted shapes and then heated to temperatures just below the melting point. At such temperatures, the powders react internally to remove porosity and fully dense articles can be obtained. 在烧结过程中，陶瓷粉末先挤压成型然后加热到略低于熔点温度。在这样的温度下，粉末内部起反应去除孔隙并得到十分致密的物品。 An optical fiber contains three layers: a core made of highly pure glass with a high refractive index for the light to travel, a middle layer of glass with a lower refractive index known as the cladding which protects the core glass from scratches and other surface imperfections, and an out polymer jacket to protect the fiber from
