针对常规水声数据采集系统存在的传输距离近、通信带宽窄,不适合大量水声数据远程传输的缺点,研究开发了数字微波通信方式的远程水声数据采集系统;给出了远程水声数据采集系统的硬件结构,并设计完成了系统的操作软件;该系统采用现有的硬件产品,缩短了开发周期,将计算机网络里面广泛应用的TCP/tP协议成功运用在采集系统中,解决了海面微波信道传输的可靠性问题;经海上实验验证,该系统具有小型化、结构简单、远距离、高传输速率、低误码率及无失真传输等的优点。
To overcome the shortcomings of conventional acoustic data acquisition system, such as, short distance of transmission, narrow bandwidth of communication, and not suitable for transmitting a large number of acoustic data, a digital microwave communication mode of remote acoustic data acquisition system is developed. The hardware structure and the operating software are given. This system uses the existing hardware prodtucts, which shortens the development cycle. The application of TCP/IP protocol in the acquisition system enhanced the reliability of data transmission by microwave channel across the sea. The experiment over the sea shows that the system has several advantages, for example it is small, simple, and mobile. The features of this system on long transmission distance, high transmission speed, low error rate, and remote transmission without distortion are quite useful in practical use.
