摘要
针对原有鱼雷合作声信标信号产生电路使用分立元件设计实现,长期服役可靠性下降、功能单一、体积庞大等缺点,提出借助大规模集成电路,采用"单MCU方案"设计实现了新型数字化信号发生器。该信号发生器性能与原系统完全兼容,在大幅提高可靠性与可维修性的同时,提供了信号体制设定功能,增强产品使用的灵活性;采用多种电气隔离手段,确保其能够在强电磁干扰环境中可靠工作。
A digital signal generation circuit with VLSI and Single MCU scheme is designed to overcome the disadvanta- ges of existing signal generation circuit designed with discrete component in torpedo synchronous acoustic beacons, such as reducing reliability with long-term service, single function, huge volume and so on. The digital signal generation circuit with the function of set signal parameters is not only completely compatible with original system, but also has the advantages of used flexibly, high reliability and maintainability. Meanwhile, manifold electrical isolation methods are used to insure the digital signal generation Circuit working reliably in strong electromagnetic interference environment.
