【摘要】：近年来电梯保有量越来越多以及电梯老龄化日趋严重致使故障频发。然而由于现有的电梯远程监控系统存在一些缺陷而没有得到广泛应用，因此目前主要依靠被困乘客和现场保安等人员发现电梯的故障，常常由于故障的发现或通知不及时，导致救援时间过长，引起被困乘客恐慌的情绪，甚至造成了人员的伤亡。现有电梯远程监控系统主要存在的问题是不同品牌的电梯采用不同的标准，如采用不同的通讯协议以及不同的硬件接口。这些监控系统只能在特定品牌的电梯上配套使用而且系统价格昂贵。针对这些现状，本文以开发适用于所有品牌电梯的远程实时监测报警系统为目的，融合了多种物联网技术，包括ZigBee技术、GPRS技术与RFID技术，提出了一种由独立的传感器、终端采集器、GPRS传输网络和监控中心组成的系统设计方案。本系统属于监测系统，，只采集报警信息，不对电梯进行控制，对原电梯系统本身不产生任何影响，通过使用独立的传感器采集故障信息，可适用于所有的井道式电梯。传感器采集电梯运行的各种状态数据，采集到的数据通过ZigBee无线网络传输给机房终端，机房终端采集电梯超速信号和RFID维保信息，然后将这些数据整合在一起通过GPRS网络传输至监控中心。最后，在基于VB设计的监控中心PC机界面上，实现电梯运行状态实时显示、故障信息管理、维保信息管理等功能。采用ZigBee无线网络不仅解决了井道内布线困难的问题，而且实现了应用一个GPRS模块服务于一幢大楼内多台电梯的功能，节省成本。RFID维保刷卡模块有利于政府质监部门实时掌握和有效监督电梯的安检、维保等状况。结果表明：该方案设计合理，为电梯安全监管提供了新的技术支撑。最后对硬件部分和软件部分进行了多次联合调试，各功能运行正常。轿厢数据采集器与机房终端之间能通过Zigbee模块正常通信，GPRS模块能把数据成功发送到监控中心，监控中心的上位机能正常接收并显示电梯的实时状态数据，语音安抚模块能根据上位机发出的指令播放不同的安抚音频。系统达到了预期的研究目的。
[Abstract]:In recent years, there are more and more elevator holdings and the aging of elevators lead to frequent failures. However, the existing elevator remote monitoring system has some defects and has not been widely used. So at present, mainly rely on trapped passengers and security personnel to find the elevator fault, often because the fault detection or notification is not timely, resulting in the rescue time is too long, causing the trapped passengers panic mood. The main problem of the existing elevator remote monitoring system is that different brands of elevators adopt different standards. Such as different communication protocols and different hardware interfaces. These monitoring systems can only be used in a particular brand of elevators and the system is expensive. In order to develop the remote real-time monitoring and alarm system for all brand elevators, this paper integrates many kinds of Internet of things technologies, including ZigBee technology. GPRS technology and RFID technology, a system design scheme composed of independent sensor, terminal collector, GPRS transmission network and monitoring center is proposed. The system belongs to the monitoring system. Only the alarm information is collected, the elevator is not controlled, and there is no influence on the original elevator system. By using independent sensors to collect fault information, it can be applied to all kinds of shaft elevators. The sensor collects all kinds of state data of elevator operation, and the collected data is transmitted to the terminal of computer room through ZigBee wireless network. The terminal of computer room collects elevator overspeed signal and RFID maintenance information. Then the data is integrated to the monitoring center through the GPRS network. Finally, in the PC interface of the monitoring center designed based on VB, the elevator running status can be displayed in real time and the fault information can be managed. Maintenance information management and other functions. The use of ZigBee wireless network not only solves the difficult problem of wiring in the well, but also realizes the function of using a GPRS module to serve multiple elevators in a building. The cost saving. RFID maintenance and credit card module is conducive to the government quality supervision department to grasp and effectively supervise the elevator security inspection, maintenance and other conditions. The results show that the design of the scheme is reasonable. It provides new technical support for elevator safety supervision. Finally, the hardware part and the software part are debugged several times, each function is running normally. The data acquisition device of the car and the terminal of the computer room can communicate normally through Zigbee module. The GPRS module can successfully send the data to the monitoring center, and the upper function of the monitoring center can receive and display the real-time status data of the elevator. The speech conciliating module can play different conciliatory audio according to the instruction of the upper computer.
