【摘要】 为了提高鱼群探测器的应用范围,进一步扩展探测器的功能,该文提出一种基于ARM9控制器和嵌入式Linux操作系统的鱼群探测器的设计方法,并在此基础上开发并完成系统的硬件电路和相应的系统应用软件。该鱼群探测器是基于S3C2440微处理器,采用GPIO接口控制发射器发射电子脉冲,通过传感器将其转换成声波并发射到水中,接收器接收回声,并通过解码芯片进行解析;最后,通过触摸屏控制系统采集数据,由声纳装置记录下声纳曲线。实际应用表明,该探测器具有较好的效果。更多还原

【Abstract】 In order to expand the application and function of the fish detector,we propose a method of detector based on ARM9 processor and embedded Linux operating system.Besides,we design and accomplish the system including hardware circuit and application software.The fish detector is based on S3C2440 processor,using GPI0 interface to control transmitter to deliver electronic pulse.Sound waves are converted and launched to the water with sensor.Then receiver receives echoes,parsing through the decoder chip.In the end,we collect data through the touch screen control system,utilize sonar device to record sonar curve.The practical applications show good performance of the detector.更多还原
