摘　　要：目前大多数继电保护装置的开入量遥信直接由硬件电路处理生成,这种方式对温度适应性差,易发生误变位,导致电路故障。为此,提出用微处理器对开入量进行软件处理,配合外围硬件电路实现多路开入量高速采集,生成具有高分辨率、高可靠性的遥信数据。The remote signal of most relay protection devices is generated by hardware circuit,which has poor adaptability to temperature and is prone to misalignment,resulting in circuit failure.Therefore,it is proposed to use microprocessor for software processing of input potential,to realize high-speed acquisition of multi-channel input in combination with peripheral hardware circuit,resulting in remote signal data with high resolution and reliability.
