摘要
针对目前电梯控制柜电磁兼容检测方法智能化程度低、操作繁琐且缺乏电梯系统状态监测的问题,文章设计了一套电梯控制柜电磁兼容检测控制系统。其构建了“上位机+下位机”的控制系统架构,开发了基于ARM的嵌入式控制器,设计了自动检测流程和控制系统上下位机应用软件,使电梯控制柜具备传感器信号采集、CAN总线通信等功能,实现了控制柜电磁兼容性能化检测的以及电梯系统状态的实时监测。使用该系统对电梯控制柜进行传导抗扰度、电压暂降、电压中断、电快速瞬变脉冲群检测和浪涌试验,并对传感器信号异常、电源故障和通信异常故障进行模拟试验,结果显示,该电梯控制柜电磁兼容检测控制系统运行稳定、数据采集准确、操作简单,且对各种故障类型均能准确、高效识别。该系统可以满足电梯生产厂家及检测机构的电磁兼容检测需求,且与以往检测方法相比,减少约67%的检测人力投入。
In response to the problems of current electromagnetic compatibility testing methods for elevator control cabinets,including low intelligence,cumbersome operation,and lack of elevator system status monitoring,this paper proposes an electromagnetic compatibility testing method for elevator control cabinets and designs a set of electromagnetic compatibility testing and control system for elevator control cabinets.The author constructed an"upper computer+lower computer"control system architecture,developed an embedded controller based on ARM,designed application software for upper and lower computers of the automatic testing process and control system,implemented such functions as sensor signal acquisition and CAN bus communication for elevator control cabinets,and realized the real-time monitoring of electromagnetic compatibility testing of elevator control cabinets and elevator system status.Then,the author used this system to carry out the conducted immunity,voltage dip,voltage interruption,electrical fast transient pulse group and surge tests on elevator control cabinets,and conducted simulation tests on elevator control cabinets for sensor signal abnormalities,power supply failures,and communication anomalies.The results show that the electromagnetic compatibility testing and control system of the elevator control cabinet operates stably,with accurate data collection and simple operation,accurately and efficiently identifies various types of faults,meets the needs of elevator manufacturers and testing institutions for electromagnetic compatibility testing,and compared with previous testing methods,reduces testing manpower input by about 67%.
