电梯

Say elevator is remittent enjoyment, that is to point to by elevator person, for the person to making elevator, compare them to be in remittent searching is again appropriate did not pass.

都说电梯是上上下下的享受，那是指乘电梯的人，对制造电梯的人来说，比喻他们在上上下下间求索是再恰当不过了。

That the electric elevator is that the call sign waits to work according to the outside as well as oneself controls law in fact, but call for is random , the electric elevator is that one people machine is each other dyadic in fact control system , the way the simple use sequential control or logic is controlled being that lift control system adopt the random logic therefore can not be satisfied with controlling call for's,controls.

实际上电梯是根据外部呼叫信号以及自身控制规律等运行的，而呼叫是随机的，电梯实际上是一个人机交互式的控制系统，单纯用顺序控制或逻辑控制是不能满足控制要求的，因此，电梯控制系统采用随机逻辑方式控制。

TRUMP's solemn expression_r ,the door of the bordroom is closed ,there are two elevators there ,one is upward for the survivers weho are going to enjoy their luxurious life and the other one for the eliminated one who is gonna say goodbye to this place and go back home ,the later one push his luggage case into the elevater and go downstair ,there a yellow taxi is waiting ,then the car goes ,with one of the competiters,the brown door upstairs is open ,then shut down ,that's the things that happened ,tommorrow it gonna be go on and who is going to get out?

然后就是 TRUMP 严肃的表情，以及会议室的门被关上，然后，有两个电梯，没有出局的人，推着自己的行李箱走进向上的电梯，客气的话会跟出局的那个打个招呼，然后门关上，出局者等着其他人上去后，拉着自己的行李箱走进向下的电梯，然后镜头切换到楼下的门，门打开，街上的纽约公司的 TAXI 开走，带走了一个竞争者，楼上的棕色的门被拉开，然后关上，这就是这一天的事情，明天还要重复，明天谁将会被淘汰？

Next , I am coming into more deeping to analysing elevator's structure and its electric principle and elevator's working principle.

首先，从电梯的历史和其技术特点及其末来的前景深入地分析电梯的各个方面的内涵，加深对电梯的理解。

And elevator machine room has a different speed limiter calibration are: roomless elevator shafts of the speed limiter is located at the top, and its space-site calibration, verification conditions, operation more difficult, so No machine room elevator overspeed governor check the site work in the province and even across the country are rarely carried out.

和电梯机房有不同的限速校准是：对限速器无机房电梯井位于首位，其空间现场校准，核查情况，经营更加困难，因此没有机房电梯限速器检查现场工作在全省乃至全国都少见。

First according to the hydraulic pressure elevator system diagram, use the machine design and hydraulic transmission knowledge calculates the diameter of the plunger, cylinder tube wall thickness as well as cylinder bottom thickness; second, through the examination confirmation to the obtained result to complete the work of cylinder design; Simultaneously has carried on the component choice and the computation; Through to the system calorific capacity computation the and the volume of cooling water while the fuel tank cools when needs to complete the hydraulic pressure elevator fuel tank design; Based on the system oil stream condition to calculated the tube internal pressure lose, the local pressure loss as well as the all of the pressure lose to carried on the system checking calculation; Finally through the consult correlation design handbook to calculation and examines the belt, the band pulley, the axis, as well as the key, has completed the hydraulic pressure elevator pumping station transmission system design.

首先根据液压电梯系统原理图，利用机械设计与液压传动等方面的知识计算出柱塞的直径、缸筒的壁厚以及缸底厚度，并对所得结果进行校核验证完成了工作油缸的设计；同时进行了元件的选择和计算；其次，通过系统发热量的计算和油箱冷却时需要的冷却水量的计算完成了液压电梯油箱的设计；依据系统油流状态计算出管内压力损失、局部压力损失以及总压力损失进行了系统的验算；最后通过查阅相关设计手册对带、带轮、轴、以及键进行设计计算和校核，完成了液压电梯的泵站传动系统的设计。

The design method of 4 floor elevator model is introduced ,it is focus on the structure of the model,the setting of main registering signal ,outer calling signal and elevator well signal, speed curve setting and operating, and design of its PLC control system, and so on, the basic function of all centralized alternative elevator has been run on the model.

介绍了四层四站电梯仿真模型的设计方法，着重讨论了模型电梯的结构，轿内主令信号、厅外呼梯信号及井道信号的设置，速度曲线的给定和实现以及PLC控制系统的设计，并在此模型上，实现了全集选电梯的功能。

The electric elevator controlling has adopt two kinds way at present commonly, one being to adopt PC to control an element as the signal, accomplish electric elevator signal acquisition , operation state and functional setting up, that the automation controller and collection selections realizing an electric elevator run a function , drag moving is to come to be completed from the frequency transformer under the control of; The selections controlling way second kinds using programming controller to substitute PC realizing signal collection is controlled.

目前电梯的控制普遍采用了两种方式，一是采用微机作为信号控制单元，完成电梯信号的采集、运行状态和功能的设定，实现电梯的自动调度和集选运行功能，拖动控制则由变频器来完成；第二种控制方式用可编程控制器取代微机实现信号集选控制。

With rapid technological development of gearless permanent magnet synchronous, it is required that the weighting system is able to not only provide signals for under load and full load to prevent overload, but also present and feedback precise weight signal to transducer, which automatically adjusts starting torque of motor by weighting signal and starts elevator smoothly.

随着无齿轮永磁同步电梯技术的迅速发展，要求称重系统不仅提供轻载、满载信号、限制超载、更应能够给出准确的称重信号，将称重信号反馈给变频器，变频器根据称重信号，自动调整电机起动力矩，使电梯平稳起动，称重系统也由限制超载的辅助部件，转变成为实现电梯起动力矩补偿，防止起动侧溜的重要功能部件。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
