Abstract
microelectronic technology's development， elevator's dragging way and the control method has had the very big change, the exchange velocity modulation is the current elevator dragging main development direction。 At present the lift control system mainly has three control modes: Following electric circuit control system （“early installment elevator many black—white control system）， PLC control system， microcomputer control system。 Because the black—white control system the failure rate is high, the reliability is bad， control mode not nimble as well as consumed power big and so on shortcomings, at present has been eliminated gradually. Although the microcomputer control system has the strong function in the intelligent control aspect, but also has the interference rejection to be bad， the system design is complex, generally the servicemen master flaws with difficulty and so on its service technology. But PLC control system， because moves the reliability to be high, the use service is convenient, anti-jamming, the design and the debugging cycle is short and so on merits, time is taken seriously the people and so on merits， have become present use most control modes in the lift control system， at present also widely use in the tradition black-white control system's technological transformations。 个人收集整理，勿做商业用途文档为个人收集整理，来源于网络
The origin and development of the elevator
Elevator in the Chinese dictionary explanation： building electricity powered lift, instead of walking up and down the stairs.
When it comes to lift from the origin of the 2600 BC Egyptians built in Pyramid using the original lifting system to start, but this kind of crane energy are human。 By 1203， two French monastery installed a crane, the difference is just the machine is the use of donkey as power, load by around a large drum rope for hoisting。 This method has been used to modern until Watt invented the steam engine, in about1800， mine owners can use the crane to mine in coal transportation。
For hundreds of years， people made various types of elevators, they all have a common defect： as long as the lifting rope snaps， lifting ladder he rapidly hit bottom layer. 1854 Otis design a brake： in the lift platform mounted on top of a truck with a spring and a brake lever and Lift Wells Road on both sides of the guide rail is connected with the lifting rope, wagon springs, this is only the lifting platform weight is sufficient to pull spring, avoid contact with the brake lever。 If the rope breaks， truck spring will pull the ends of vertical weakened, and the brake lever occlusal， can be firmly fixed without in situ platform continues to fall。 " Safe lifting ladder” invention success! For a time， Otis has become the center of attention. The first lift not Otis invented, but he was the first” safe” lift the inventor. ” Security" this concept not only create lift industry, but also for those who want to build more tall buildings to add more available space design are open thoroughfare.本文为互联网收集,请勿用作商业用途个人收集整理，勿做商业用途
However it can be called the elevator （ electric energy to drive the elevator ) of the product should be at the beginning of the twentieth Century emerged.
Elevator technology development trend
（1）: green environmental protection concept is the development trend of elevator。 Have expert prophecy" who first introduced green products and market of race to control， who will grasp the market competition initiative”. Development trend to basically have ： the continuous improvement of product design, production of environmental protection type low power consumption, low noise， no leakage， no water leakage， no electromagnetic interference, no oil pollution of the elevator hoistway guide. Elevator traction with nylon synthetic fiber rope, steel belt without lubricating oil pollution traction mode。 Elevator decoration will use no (little ） environmental pollution material. Elevator no—load rise and full of descending motor power regeneration recycling technology. The installation of lifts will be installed without scaffolding. Elevator parts in the production and use of the process has no effect on the environment （ such as brake pads must not use asbestos ) and materials can be recycled。 (2) the application of Bluetooth technology in elevator。 Installation of elevators knows line, on line is time—consuming， laborious， easy wrong job。 If the control screen and calling system through the Bluetooth wireless call will be connected to the elevator control another revolution at the same time bring us enormous benefits. A installation period will be reduced by more than 30％， the direct benefits of reduced installation costs， customers from booking to use lift cycle cost reduce the ladder and improve cash flow rate。 B on the elevator using Bluetooth technology will make the elevator control system using a large amount of the latest and fastest computer， which will further improve the elevator machine reliability， fault rate is greatly reduced， the control precision is further increased, the result is the elevator more comfortable more accurate flat layer。 C is a good solution to the elevator control and peripherals compatible and contact. In particular can take the elevator and escalator induction to the building management system or intelligent management district system。 本文为互联网收集,请勿用作商业用途文档为个人收集整理,来源于网络

摘要
随着科学技术的发展、近年来，我国的电梯生产技术得到了迅速发展．一些电梯厂也在不断改进设计、修改工艺。更新换代生产更新型的电梯，电梯主要分为机械系统与控制系统两大部份，随着自动控制理论与微电子技术的发展，电梯的拖动方式与控制手段均发生了很大的变化，交流调速是当前电梯拖动的主要发展方向。目前电梯控制系统主要有三种控制方式：继电路控制系统(“早期安装的电梯多位继电器控制系统）、PLC控制系统、微机控制系统。继电器控制系统由于故障率高、可靠性差、控制方式不灵活以及消耗功率大等缺点，目前已逐渐被淘汰。微机控制系统虽在智能控制方面有较强的功能，但也存在抗扰性差，系统设计复杂，一般维修人员难以掌握其维修技术等缺陷。而PLC控制系统由于运行可靠性高，使用维修方便,抗干扰性强，设计和调试周期较短等优点，倍受人们重视等优点，已成为目前在电梯控制系统中使用最多的控制方式，目前也广泛用于传统继电器控制系统的技术改造。
电梯的起源与发展
电梯在汉语词典中的解释为：建筑物中用电作动力的升降机，代替步行上下的楼梯。
说到电梯的起源要从公元前2600年埃及人在建造金字塔时使用了最原始的提升系统说起，但这一类起重机的能源均为人力.到了1203年，法国的二修道院安装了一台起重机,所不同者只是该机器是利用驴作为动力，载荷由绕在一个大滚筒上的绳子进行起吊。此种方法一直沿用到近代直到瓦特发明了蒸汽机，约在1800年,煤矿主才能利用起重机把矿井中的煤输送上来。
数百年来人们制造过各种类型的升降梯,它们都具有一个共同的缺陷：只要起吊绳突然断裂，升降梯便急速地坠落到底层。1854年奥的斯设计了一种制动器：在升降梯的平台顶部安装一个货车用的弹簧及一个制动杆与升降梯井道两侧的导轨相连结，起吊绳与货车弹簧连结，这样仅是起重平台的重量就足以拉开弹簧，避免与制动杆接触。如果绳子断裂,货车弹簧会将拉力减弱，两端立该与制动杆咬合，即可将平台牢固地原地固定免继续下坠.“安全的升降梯”发明成功了！一时间，奥的斯成了众人注目的中心。第一台升降机并非奥的斯所发明，但他却是第一台“安全"升降梯的发明者.“安全”这一概念不仅开创了升降梯工业，而且也为那些想建造更高层建筑物以增加更多可利用空间的设计们打开了通途。
然而真正能够称为电梯（用电能驱动升降梯)的产品应该是在20世纪初才出现的。
电梯技术发展趋势
(1）环保:绿色理念是电梯发展总趋势.有专家预言“谁最先推出绿色产品并抢占市场，谁就掌握市场竞争主动权”。发展趋势主要有：不断改进产品的设计，生产环保型低能耗、低噪声、无漏油、无漏水、无电磁干扰、无井道导轨油渍污染的电梯。电梯曳引采用尼龙合成纤维曳引绳，钢皮带等无润滑油污染曳引方式.电梯装璜将采用无(少）环境污染材料。电梯空载上升和满载下行电机再生发电回收技术。安装电梯将无需安装手脚架。电梯零件在生产和使用过程中对环境没有影响（如刹车皮一定不能使用石棉）并且材料是可以回收的.（2)蓝牙技术在电梯上应用。安装过电梯的人都知道放线、对线是费时、费力、极容易错的工作。如果控制屏与召唤系统通过蓝牙技术连接起来实现无线召唤将会是电梯控制的另一场革命同时为我们带来巨大好处。A安装期将减少30％以上,其直接好处是降低安装成本，客户也因从订梯到使用电梯周期费用减少和提高现金周转率。B在电梯上使用蓝牙技术一定会使电梯控制系统大量使用最新最快微机,这将会进一步提高电梯整机可靠性,故障率大大降低，控制精度也进一步提高，带来的结果是电梯更加舒适，平层更加准确。C很好地解决了电梯控制与外围设备的兼容和联系。特别是可以把电梯和扶梯归纳到大楼管理系统或智能化管理小区系统中.本文为互联网收集，请勿用作商业用途个人收集整理,勿做商业用途
