摘要
在水下制导武器的研究、开发、外场试验中,都需要采集水声基阵的接收信号,并实时记录采集数据,根据需要进行现场数据分析和实时或离线处理。研究水声信号采集系统对有效提高制导武器的数据分析性能具有重要意义。提出一种基于ZigBee和模糊PID控制的水声信号采集系统设计方案,通过ZigBee识别模型中的识别器获取ZigBee水声信号,进行信号滤波和中频放大设计,实现对干扰噪声的有效抑制。实验结果表明,设计的系统具有较好的实时数据采集和信号处理性能,通过模糊PID控制提高信号检测性能,系统的实时性和人机交互性好,在水声信号处理和信息采集等领域具有较好的应用价值。
In the research of underwater guidance weapons development and field test ,it needs to receive the signal ac‐quisition of underwater acoustic array ,records the data for collection .According to the need ,field data analysis and real‐time or offline processing are taken .It is important to analyze performance data to effectively improve guided weapons research of underwater acoustic signal acquisition system .An underwater acoustic signal acquisition system is proposed based on ZigBee and fuzzy PID control .The underwater acoustic signal is obtained with the ZigBee recognizer and identification model ,signal filtering and intermediate frequency amplifier design are taken ,and the effective suppression of interference noise is obtained . The experimental results show that the system has real‐time data acquisition performance ,and signal processing performance is good ,to improve the signal detection performance through the fuzzy PID control .Human‐computer interaction perform‐ance is good ,and it has good application value in underwater acoustic signal processing and information acquisition and other fields .
