摘要
设计了一种双电源自动转换开关信号检测电路。以PIC18F458为核心处理器,利用其A/D转换、CCP输入捕捉功能完成了双电源自动转换开关的电压、频率信号检测电路的硬件设计,并编写了相应的检测软件。该检测电路抗干扰性高、精度高,具有成本低、易维护的优点。
A signal detection circuit for dual power automatic transfer switching equipment （ATSE） was de-signed. Taking PIC18F458 as core processor, the hardware design of voltage and frequency signal detection circuit for dual power ATSE was done with its A/D conversion and input catch functions. The relative detection software was programmed too. With high anti-jammlng performance and precision, the detection circuit has merits of low cost and easy maintenance.
