摘要
为实现对核聚变装置EAST极向场12套电源的现场层的实时控制,构建了基于QNX平台的电源分布式现场层控制系统,利用以太网现场总线控制器实现对极向场电源状态的实时控制,并通过Modbus/UDP协议实现和上位机的数据的实时通信,实时控制周期可达4ms。
Considering the real-time control of EAST PF （poloidal field） power supply site equipments of nuclear fusion device, a control system based on QNX6.3.2 6RTOS was constructed, which having Ethernet Fieldbus controller employed to real time control PF power state and to communicate with principal computer through Modbus UDP protocol, and a 4ms real-time control cycle can be achieved.
