对一款电梯紧急对讲系统呼叫电路的分析与改进
|
摘要
为了保证电梯紧急报警时对讲装置有效,按照电梯相关技术规范的要求,应当定期对电梯紧急对讲装置进行检验。通过对定期检验结果的统计分析,发现此类装置存在未按要求设置、使用说明缺失、损坏、失效以及管理欠缺等诸多问题。基于对一例改装的电梯紧急对讲装置的失效案例分析,介绍了其元件的组成、工作原理以及电梯紧急对讲系统的呼叫流程等。分析探讨了电梯紧急对讲装置的失效原因和存在问题,并对电梯紧急对讲装置提出了改进方案、整改措施以及管理方面的意见和建议。通过对电梯紧急对讲装置的改进和完善,解决了电梯紧急对讲装置有效通话的问题,避免了因电梯紧急对讲装置失效致使乘客焦急等待救援采取自救行为,而引发的意外事故。
To ensure the effectiveness of the intercom device for elevator emergency alarm,regular inspection is required for the elevator emergency intercom device according to relevant elevator technical specifications. Through statistical analysis of the results of periodic inspection,these devices were found to have such problems as being not installed according to the requirement,missing,damaged or invalid operational instructions,and management defect. Based on a failure case analysis of a modified elevator emergency intercom device,an introduction was made of its component composition and working principle as well as the call process of the intercom system. Causes of failure and existing problems of the device were analyzed and discussed,and improvement schemes,rectification measures and management suggestions were proposed. Through improvement of the intercom device in this case,effective call was ensured for this type of emergency intercom devices,and accidents caused by ineffective intercom devices or anxiously waiting passengers taking self-help actions were avoided.
