过程层智能化是变电站智能化的前提和基础；作为过程层核心设备之一，智能终端在保障GOOSE通信可靠性、实时性的基础上，一方面应具备传统断路器操作箱的逻辑功能，另一方面还应实时监测断路器的运行状态，为变电站过程层的高级智能化奠定基础。针对以上需求，结合126 kV智能开关设备的结构特点，采用ARM+FPGA的构架模式，设计开发了一款智能终端，实现了断路器的运行状态实时采集，及断路器、隔离开关、接地刀闸等实时逻辑闭锁控制。设计中ARM主要负责过程层 GOOSE 通信、开入开出的采集处理等，FPGA 负责开入开出的扩展和装置内部逻辑控制，以满足装置的实时多输入、多输出的需求。现场试验测试表明，装置性能符合企业标准，具有较高的现实意义和应用价值，设计中也考虑了后续高级功能实现的有效接口。

Intelligentilization of process layer is the premise and basis of smart station. Intelligent terminal, as one of the core equipment in smart substation, should ensure GOOSE communication reliability and real-time request. Except for those, for one hand, it should possess the logic function of traditional circuit breaker operation box, for the other hand, it should real-time monitor the operation state of circuit break, supplying a foundation for the senior intelligentilization of substation process layer. In response to the questions, combined with the structure characteristic of 126 kV intelligent circuit breaker controller and based on the chip frame of ARM+FPHA, a novel intelligent terminal is developed to implement the real-time monitoring of operation state of circuit breaker, and the logic blocking control of the circuit breaker, switcher, grounding switcher, etc. The ARM is mostly responsible for the GOOSE communication, and the collecting and processing of binary signals, while the FPGA is used to extend the I/O ports and the internal logic control to fulfill the requirements of real-time multi input and output to the intelligent circuit breaker controller. Practical tests show that the developed device keeps in accordance with the standards, and can be applied in field. In the design, the effective ports for implementing futher senior functions are also considered.
