Title   Weak line selection circuit design based on the distributed modules                                                  

Abstract This paper is for the traditional relays weak line selection system improvements，use the module replace the relay, use the bus technology to realize signal communication between the module and the module as well as computer. Through PC programming we can realize the functions such as self-sustaining, lockout, delay, pulse and so on easily and quickly. In this paper, it includes weak line selection control circuit of the breaker, weak line central signal system, breaker position signal circuit. In the section of weak line selection control circuit of the breaker, it introduced the functions of automatic reset, mistakenly selected reversion, object selection and object locking in detail. In the weak line central signal system, it contains incident signal circuit, warning signal circuit and flash signal circuit, and it has the operating functions of bright screen and dark screen. In the section of weak line selection control circuit of the breaker, it introduced the functions of automatic reset, mistakenly selected reversion, object selection and object locking in detail. It describes working principle and effect of every circuit. Due the host computer adopt King View control system, the paper also briefly describes the method of the module hardware connection and King View programming hair.
