【摘要】：近年來，隨著中國經(jīng)濟和社會的快速發(fā)展，特別是城鎮(zhèn)化進程的加快，電梯保有量迅猛增長。作為一種與人民群眾生命安全息息相關(guān)的垂直運輸設(shè)備，它的可靠、安全運行受到廣泛關(guān)注。目前，維護保養(yǎng)公司的定期維修保養(yǎng)和質(zhì)量監(jiān)管部門的定期檢測檢驗是保障電梯運行安全重要組成部分。隨著電梯數(shù)量快速增長與維護管理人手緊缺之間的矛盾日益突出，如何及時發(fā)現(xiàn)電梯安全隱患，并采取有效的措施加以防范處理，成為電梯監(jiān)管部門、維護保養(yǎng)單位和使用單位等多方必須共同面對的課題。多個城市的試點運行表明：電梯運行狀態(tài)監(jiān)測裝置為提高電梯運行安全做了有意義的探索，特別是在提高電梯在發(fā)生緊急狀況時的救援速度方面發(fā)揮了積極作用。 論文主要工作包括：①分析現(xiàn)有電梯安全監(jiān)管模式存在的突出問題及其發(fā)展趨勢；分析了電梯安全監(jiān)測技術(shù)的國內(nèi)外研究進展，所研究結(jié)論對于現(xiàn)有電梯運行安全監(jiān)測技術(shù)及電梯運行狀態(tài)監(jiān)管模式等存在的問題的解決具有重要的指導(dǎo)價值。②提出基于電流信號的電梯運行狀態(tài)監(jiān)測方法及相關(guān)理論，介紹了基于電流信號的非接觸式電梯運行狀態(tài)監(jiān)測方式，研究了基于電梯主電路電流信號的電梯運行狀態(tài)監(jiān)測方法。研究有助于對電梯運行狀態(tài)的實時主動監(jiān)測；③開發(fā)了基于電流的電梯運行狀態(tài)監(jiān)測終端。在分析終端設(shè)計要求的基礎(chǔ)上，，采用先進傳感、GPRS通信、高性能信號處理等新技術(shù)，開發(fā)基于電流信號的電梯運行狀態(tài)監(jiān)測終端，實現(xiàn)對運行過程中電梯運行狀態(tài)的實時監(jiān)測，為建立集監(jiān)測、預(yù)測、診斷、控制和管理決策于一體的電梯安全監(jiān)控新模式奠定基礎(chǔ)。在對終端硬件進行標定的基礎(chǔ)上，結(jié)合遠程監(jiān)測平臺，對電梯運行狀態(tài)遠程監(jiān)測系統(tǒng)作了實驗研究。測試實驗表明，終端可實現(xiàn)對電梯多種運行狀態(tài)的實時監(jiān)測，當(dāng)電梯發(fā)生故障時，可及時向指定的管理人員發(fā)送報警信息。
[Abstract]:In recent years, with the rapid development of China's economy and society, especially the acceleration of urbanization, elevator ownership has increased rapidly. As a vertical transportation equipment, it is closely related to people's lives and safety. Its reliable and safe operation has received extensive attention. At present. The periodic repair and maintenance of the maintenance company and the regular inspection and inspection of the quality supervision department are the important parts of ensuring the safety of the elevator operation. With the rapid increase in the number of elevators and the shortage of maintenance and management personnel, the contradiction between the number of elevators is increasing. Out. How to discover the hidden trouble of elevator safety in time and take effective measures to prevent and deal with it become the supervision department of elevator. The pilot operation in many cities shows that the elevator operating condition monitoring device has made a meaningful exploration to improve the elevator operation safety. In particular, elevators play an active role in improving the rescue speed in emergency situations. The main work of this paper is to analyze the outstanding problems and the development trend of the existing elevator safety supervision mode. The research progress of elevator safety monitoring technology at home and abroad is analyzed. The conclusion has important guiding value for the existing elevator operation safety monitoring technology and elevator operating state supervision mode. 2. The method of elevator running state monitoring based on current signal is put forward. Relevant theory. This paper introduces a non-contact elevator running condition monitoring method based on current signal. The monitoring method of elevator running state based on the current signal of elevator main circuit is studied, which is helpful to the real-time active monitoring of elevator running state. (3) the elevator operating state monitoring terminal based on current is developed. On the basis of analyzing the design requirements of the terminal, new technologies such as advanced sensor GPRS communication and high performance signal processing are adopted. The elevator running state monitoring terminal based on the current signal is developed to realize the real-time monitoring of the elevator running state in the course of operation to set up the monitoring prediction and diagnosis. The new mode of elevator safety monitoring, which integrates control and management decision, lays the foundation. On the basis of calibrating the terminal hardware, the remote monitoring platform is combined. The test results show that the terminal can realize the real-time monitoring of the elevator running state, when the elevator breaks down. Can send alarm message to designated manager in time.
