QBZ-63,80,120 / 660(380) F starter is altered because of its problems in operation underground,by the start-up method of combining software and hardware.The starter is as a multi-functional intelligent starter to monitor realtimely the working equipment through the external circuit,communications interface circuits.It not only achieves to interlock between main and standby fans,but also realizes the interlocking between circuit and methane breaker,the Chinese characters shown,the memory,the interactive communication,and so on.The tryout in coal mine shows that the starter works well,accurately and reliably.
