摘要：随着社会日新月异的发展，扶手电梯的建设也如雨后春笋一般的发展，扶手电梯是生活中随处可见的一道靓丽的风景线。扶手电梯由一台特种结构型式链式输送机以及两台特殊结构型式的胶带输送机所组成的，布置在不属于同一层的建筑物之间单向地（方向可调）运载人员的一种运输机械装置。扶手电梯大部分布置在人流集中的地方，如：候机大厅、汽车出入站、大卖场、渡轮和地铁等等。作为城市建设重要标志之一的设施为我们提供便利的同时，扶手电梯也隐藏着不少的安全隐患。扶手电梯往往存在于人流密度甚高的商场、地铁等区域，一旦发生故障往往直接威胁人群的生命，并且会在非常短的时间内造成人流拥堵，提高事故发生几率。尤其在国民应急保护措施的理智意识仍然较弱的情况下，有一套扶手电梯故障保护系统尤为重要。然而在电梯故障之后，伴随而来的是文修人员费时费力的逐个电路检查工作，从而造成通道的人流拥挤，给经济利益带来不必要损失的同时也引发了令人值得思考的新安全隐患。本装置旨在扶手电梯发生故障的时候，能在监控中心显示出故障点，方便文修人员赶往现场并有针对性的进行检修，节省大量的时间，恢复扶手电梯的服务。37591

Design of detection device of escalator
Abstract:With the development of social change rapidly, the construction of the escalator like bamboo shoots after a spring rain as the development of city construction, The escalator is a landscape of life everywhere.. It consists of of a special type of chain conveyor and two special types of belt conveyor by a combination of in between the different floors of the building in a carrier personnel under a continuous conveying mechanical device. Widely used in stations, terminals, shopping malls, airports and underground railway and other people focused.one of the signs of facilities for my convenience at the same time, also hidden many security risks. Often exist in the crowd density is very high, subway and other regional mall escalators, once a fault occurs, often a direct threat to people's life, and will cause the crowd congestion in a very short period of time, increase the chance of accident. Especially in the national emergency protective measures of rational consciousness is still weak, is very important to have a fault protection system of escalator. However, in the elevator, the repair personnel time-consuming one by one circuit inspection work hard, resulting in the crowded channel, bring unnecessary losses to economic benefits, has also led to new security risks.When the device is designed to an elevator malfunction, can display the fault point in the monitoring center, convenient repair personnel rushed to the scene and the maintenance, save a lot of time, an elevator service recovery.
