基于视觉传达的网络模拟信号传输监测系统设计

Design of network analog signal transmission monitoring system based on visual communication

传统的网络模拟信号传输监测系统监测时,只能直接检测信号异常部分,忽略信号中压缩部分的信息,导致系统的可行性差。针对以上问题,研究基于视觉传达的网络模拟信号传输监测系统。在传统系统基础上,设计由微处理器芯片、以太网芯片和CAN总线芯片等组成的监测通信板,保证系统通信不受干扰。设计系统硬件后,设计系统的软件部分。上位机对输入进行预处理,使用AIC模型压缩感知输入信号的信息。利用滑动窗口法检测输入信号的突发异常部分。最后,通过视觉传达技术将监测结果可视化,完成对系统的设计。与两种传统监测系统进行对比实验,实验结果表明,基于视觉传达的监测系统的监测相对误差在2.36%之内,并且对监测结果的可视化显示效果好,即提出的方法具有更好的可行性。

As the traditional network analog signal transmission monitoring system can only detect the abnormal signal directly and ignore the information of the compressed part of the signal,resulting in the poor feasibility of the system,a network analog signal transmission monitoring system based on visual communication is studied.On the basis of the traditional system,the monitoring communication board composed of microprocessor chip,Ethernet chip and CAN bus chip are designed to ensure that the system communication is not disturbed.After designing the system hardware,the software part of the system is designed.The upper computer preprocesses the input and uses AIC model to compress the information of the sensing input signal.The sliding window method is used to detect the abnormal part of the input signal.The monitoring results are visualized by means of the visual communication technology to complete the design of the system.The experimental results show that,in comparison with the two traditional monitoring systems,the monitoring relative error of the monitoring system based on visual communication is within 2.36%,and the visual display effect of the monitoring results is good.In other words,the proposed method has better feasibility.
