【摘要】：近些年来电梯事故的频繁发生,使电梯安全问题受到了社会越来越多的关注。电梯监控系统是目前监控电梯运行状态的有效手段之一。然而传统的监控系统在功能上仅局限于实时监控,当电梯出现异常状况时,通常采用人工的方式完成报警,存在效率低、实时性差等缺点。随着技术的进步,电梯监控领域对监测系统在智能化分析、异常检测等方面提出了更高的需求。针对目前电梯安全监测缺乏智能分析、实时报警等问题,本文研究并开发了基于DM8148视频处理器的电梯运行状态智能监测硬件系统。在实现电梯实时监控功能的基础上,系统通过DM8148丰富的片上资源,运用相关的图像分析算法完成了对电梯运行状态的智能分析,并根据结果实现异常状况检测,包括电梯的开关门检测、电梯曝光异常现象检测等。在后端,系统通过以太网实现与云平台的交互,完成相关数据的交互及报警反馈。另外,系统扩展多种传感器支持电梯相关参数的采集和处理。测试表明,本文研究开发的基于DM8148视频处理器的电梯运行状态智能监测系统具有稳定性高、环境适应性强等特点。目前系统已通过样机测试环节,能在实际工作环境下完成对电梯运行状况的分析及部分异常状况的检测,实现报警功能的及时反馈,达到了设计要求。
[Abstract]:With the frequent occurrence of elevator accidents in recent years, more and more attention has been paid to elevator safety. Elevator monitoring system is one of the effective means to monitor elevator running state. However, the traditional monitoring system is only limited to real-time monitoring. When the elevator appears abnormal situation, it usually uses artificial way to complete the alarm, which has the shortcomings of low efficiency and poor real-time. With the development of technology, the elevator monitoring field has put forward a higher demand for intelligent analysis, anomaly detection and so on. Aiming at the lack of intelligent analysis and real-time alarm for elevator safety monitoring, this paper studies and develops an intelligent monitoring hardware system of elevator running status based on DM8148 video processor. On the basis of realizing the real-time monitoring function of elevator, the system completes the intelligent analysis of elevator running state by using the related image analysis algorithm through the abundant on-chip resources of DM8148, and realizes the abnormal condition detection according to the result. Including elevator opening and closing detection, elevator exposure abnormal phenomenon detection and so on. At the back end, the system interacts with the cloud platform through Ethernet, accomplishes the data interaction and alarm feedback. In addition, the system extends a variety of sensors to support the collection and processing of elevator related parameters. The test results show that the intelligent monitoring system based on DM8148 video processor has the characteristics of high stability and strong environmental adaptability. At present, the system has passed the test link of the prototype, can complete the analysis of the elevator running condition and the detection of some abnormal condition in the actual working environment, realize the timely feedback of the alarm function, and meet the design requirements.
