摘　　要：针对传统舰用智能脱扣器采样精度和实时性不高的缺点,介绍了一种基于高精度浮点型DSP和外扩同步采样A/D的舰用断路器智能脱扣器的设计,具有传统的三段电流保护和CAN总线通信功能。重点阐述了信号调理电路、脱扣电路和CAN接口电路。In view of the deficiency of traditional intelligent release for warship, such as low sampling accuracy and poor real-time, this article introduced the design of an intelligent release of circuit breaker for warship based on high accuracy float-point DSP and out-extended synchronous sampling A-D. This controller has functions of traditional three-phase current protection, and CAN bus communication. The article also described the signal conditioning circuit, release circuit and CAN interface circuit in particular.
