把下面几句话翻译成英文，不要在线翻译胡弄我呀，高分奖励，急

电梯是高层宾馆、高层住宅、多层厂房和多层仓库等高层建筑不可缺少的垂直方向的交通运输工具。电梯的发展历史由来已久，种类也很多，无论种类多少，就其原理是及其相似的。以往的电梯大多采用“继电器逻辑”控制，这种控制故障率高，改造困难。
随着科学技术的发展，PLC和变频器等技术在电梯的控制方面得到了广泛的应用，人们对电梯的要求也越来越高。针对以上的问题，本设计采用PLC和变频器等对电梯进行控制。PLC具有可靠性高、维修方便、编程方便等特点，使得电梯的运行安全、可靠。采用了梯形图和编程语句对设计进行调试。

Answer 1

The elevator is top hotels, high-rise residential, multi-layer plant and multi-layer warehouse high-rise building indispensable of vertical transportation tools. The development of the elevator has a long history, there are many, no matter how many kinds, its principle is and similar. Previous elevator is used mostly "relay logic" control, this control failure rate is high, transformation difficulty.

With the development of science and technology, PLC and inverter and other technology in the elevator control a wide range of applications, people on the elevator demands more and more is also high. In view of the above problem, this design USES the PLC and inverter of elevator control etc. PLC has high reliability, easy maintenance, programming is convenient wait for a characteristic, make elevator safety operation and reliable. Adopted ladder diagram and debugging of design programming statements.

Answer 2

Lift is the top hotels, high-rise residential, multi-plant and multi-storey high-rise buildings such as warehouses vertical indispensable means of transport. A long history of development of the elevator, there are many kinds, regardless of how many species, and its principle is similar. Most of the previous lift a "relay logic" control, the control failure rate, reform difficult.
With the development of science and technology, PLC and inverter control technology in the elevator has been widely used, people demand more and more elevator. To solve the above problems, this design uses PLC and inverter control of the elevator. PLC with high reliability, easy maintenance, programming and convenient, making the safe operation of the elevator, and reliable. Ladder diagram and programming statements used to debug the design.
