| Abstract: | It introduced relay style and PLC of two control modes in the power supply system of central trouble signal apparatus,and also compared with them under using the relay style control in the power supply systerm at present.The results showed that the PLC has many advantages,such as small volume,convenience assemble,simple program,high reliability and strong anti-interference ability,so its performance is superior to the former. |
