【摘要】：随着电梯越来越多的进入人们的视野，，电梯给人们带来了越来越多的便捷，电梯普及的越加广泛，电梯已成为当下建筑领域不可缺少的一部分。人们开始对电梯的人性化、舒适度的要求也越来越高。而电梯中广泛应用的配套设备如：电梯多媒体显示、电梯监控装置、电梯语音报站等的自动化程度也不断的提高。生产研发这些配套设备需要电梯模拟装置进行实际的测试。电梯模拟装置中采用标准的电梯串行传输协议，通过这些协议来控制电梯配套装置按照实际电梯运行的要求进行工作。通过这样的模拟装置不仅可以对配套装置进行功能检测，而且能够对其进行老化运行。电梯模拟装置已被广泛的应用于电梯配套设备的开发、生产检验与测试中。亦今为止电梯模拟装置由于其应能完成模拟电梯运行的全部功能，因此其规模比较庞大，不便于电梯现场使用。当电梯配套装置在现场出现问题时，需将其拆卸下来运回测试单位，进行测试与检查，这样造成了电梯维修时间和费用的增加。针对上述问题，本文在全面分析电梯运行的通信信息的基础上提出了一种基于嵌入式技术的便携式电梯测试台，它克服了传统电梯测试台的大体积、不稳定、单向等多个缺点。它把嵌入式技术引入到电梯模拟装置中，从根本上解决现场测试问题。使得生产研发不用去电梯现场既可得到标准的电梯串行传输信号，并且能够在现场对各种电梯配置装置进行实地的检测。本文提出的基于嵌入式技术的新型电梯测试台的硬件部分主要分为三个组成部分：控制主板、驱动板、嵌入式平台。控制主板主要提供发送标准的OTIS串行传输协议并将电梯运行状况发送至嵌入式平台；驱动板主要是保护电路、检测电流并且放大电流等；嵌入式平台主要搭建电梯自动检测系统实现测试台的双向显示与可控。本文详细介绍了本电梯测试台软硬件的实现，并进行了相应的研究与分析。测试台自动检测系统成功的完成了对OTIS电梯运行状态的显示和控制，提供了标准的OTIS4线RSL(Remote Serial Link)串行传输信号接口。本文最后对电梯测试台系统做了总结，为系统的下一步扩展提出了构思和展望。
[Abstract]:With more and more elevators coming into people's field of vision, elevators bring more and more convenience to people. The popularity of elevators is becoming more and more widespread. Elevators have become an indispensable part of the current architectural field. People begin to humanize the elevators. The requirements for comfort are also becoming higher and higher. And the widely used supporting equipment in the elevator such as: elevator multimedia display, elevator monitoring device, The automation degree of elevator voice station is also continuously improved. The production and development of these supporting equipment need to be tested by the elevator simulator. The elevator simulator adopts the standard elevator serial transmission protocol. Through these protocols, the elevator supporting device can be controlled to work according to the requirements of the actual elevator operation. The elevator simulation device has been widely used in the development, production inspection and testing of elevator supporting equipment. So far, because the elevator simulator should be able to complete all the functions of simulating the operation of the elevator, its scale is relatively large, and it is not convenient for the elevator to be used on the spot. It needs to be removed and shipped back to the test unit for testing and inspection, resulting in an increase in elevator maintenance time and costs. In order to solve the above problems, this paper presents a portable elevator test platform based on embedded technology, which overcomes the large volume and instability of the traditional elevator test table based on the comprehensive analysis of the communication information of elevator operation. It introduces embedded technology into elevator simulator, and solves the problem of field test fundamentally. So that the standard elevator serial transmission signal can be obtained without going to the elevator site. And can carry on the field inspection to each kind of elevator configuration device in the field. The hardware part of the new elevator test bench based on embedded technology is mainly divided into three parts: control motherboard, drive board, The main control board mainly provides the standard OTIS serial transmission protocol and sends the elevator running condition to the embedded platform, the driver board mainly protects the circuit, detects the current and amplifies the current, etc. The embedded platform mainly builds the elevator automatic detection system to realize the bidirectional display and controllable. This paper introduces the hardware and software implementation of the elevator test bench in detail, and carries on the corresponding research and analysis. The automatic testing system of the test bench has successfully completed the display and control of the running state of the OTIS elevator. Provides a standard OTIS4 line RSL(Remote Serial link) serial transmission signal interface. Finally, this paper summarizes the elevator test system, and puts forward the conception and prospect for the further expansion of the system.
