【摘要】：近年來電梯保有量越來越多以及電梯老齡化日趨嚴重致使故障頻發(fā)。然而由于現(xiàn)有的電梯遠程監(jiān)控系統(tǒng)存在一些缺陷而沒有得到廣泛應(yīng)用，因此目前主要依靠被困乘客和現(xiàn)場保安等人員發(fā)現(xiàn)電梯的故障，常常由于故障的發(fā)現(xiàn)或通知不及時，導致救援時間過長，引起被困乘客恐慌的情緒，甚至造成了人員的傷亡�，F(xiàn)有電梯遠程監(jiān)控系統(tǒng)主要存在的問題是不同品牌的電梯采用不同的標準，如采用不同的通訊協(xié)議以及不同的硬件接口。這些監(jiān)控系統(tǒng)只能在特定品牌的電梯上配套使用而且系統(tǒng)價格昂貴。 針對這些現(xiàn)狀，本文以開發(fā)適用于所有品牌電梯的遠程實時監(jiān)測報警系統(tǒng)為目的，融合了多種物聯(lián)網(wǎng)技術(shù)，包括ZigBee技術(shù)、GPRS技術(shù)與RFID技術(shù)，提出了一種由獨立的傳感器、終端采集器、GPRS傳輸網(wǎng)絡(luò)和監(jiān)控中心組成的系統(tǒng)設(shè)計方案。本系統(tǒng)屬于監(jiān)測系統(tǒng)，，只采集報警信息，不對電梯進行控制，對原電梯系統(tǒng)本身不產(chǎn)生任何影響，通過使用獨立的傳感器采集故障信息，可適用于所有的井道式電梯。 傳感器采集電梯運行的各種狀態(tài)數(shù)據(jù)，采集到的數(shù)據(jù)通過ZigBee無線網(wǎng)絡(luò)傳輸給機房終端，機房終端采集電梯超速信號和RFID維保信息，然后將這些數(shù)據(jù)整合在一起通過GPRS網(wǎng)絡(luò)傳輸至監(jiān)控中心。最后，在基于VB設(shè)計的監(jiān)控中心PC機界面上，實現(xiàn)電梯運行狀態(tài)實時顯示、故障信息管理、維保信息管理等功能。 采用ZigBee無線網(wǎng)絡(luò)不僅解決了井道內(nèi)布線困難的問題，而且實現(xiàn)了應(yīng)用一個GPRS模塊服務(wù)于一幢大樓內(nèi)多臺電梯的功能，節(jié)省成本。RFID維保刷卡模塊有利于政府質(zhì)監(jiān)部門實時掌握和有效監(jiān)督電梯的安檢、維保等狀況。結(jié)果表明：該方案設(shè)計合理，為電梯安全監(jiān)管提供了新的技術(shù)支撐。 最后對硬件部分和軟件部分進行了多次聯(lián)合調(diào)試，各功能運行正常。轎廂數(shù)據(jù)采集器與機房終端之間能通過Zigbee模塊正常通信，GPRS模塊能把數(shù)據(jù)成功發(fā)送到監(jiān)控中心，監(jiān)控中心的上位機能正常接收并顯示電梯的實時狀態(tài)數(shù)據(jù)，語音安撫模塊能根據(jù)上位機發(fā)出的指令播放不同的安撫音頻。系統(tǒng)達到了預(yù)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.
