Abstract
본 발명은 전전자 교환기의 링 릴레이 제어 장치에 관한 것으로, 특히 아날로그가입자에 대해 링 릴레이 제어 동작을 효율적으로 수행함으로써 가입자 제어 프로세서의 부하를 감소시키도록 하는 전전자 교환기의 링 릴레이 제어장치에 관한 것이다.The present invention relates to a ring relay control device of an electronic switchgear, and more particularly, to a ring relay control device of an electronic switchgear to reduce the load of the subscriber control processor by efficiently performing the ring relay control operation for the analog subscriber. .
종래 전전자 교환기의 링 릴레이 제어 장치는 다수의 가입자에게 동시에 호착신이 발생되는 경우, 착신 가입자가 오프 훅 할 때까지 가입자 제어 프로세서가 가입자 보드 측에 링 릴레이 구동 데이터와 링 릴레이 복구 데이터를 반복해서 츨력해야 하므로, 가입자 제어 프로세서의 부하가 증가되어 가입자 제어 프로세서의 제어 처리 속도를 저하시키게 되는 문제점이 있었다.In the conventional ring relay control device of an electronic switchboard, when a call is made to a plurality of subscribers at the same time, the subscriber control processor repeatedly repeats ring relay driving data and ring relay recovery data on the subscriber board until the called subscriber is off-hook. Since it must be output, there is a problem that the load of the subscriber control processor is increased to reduce the control processing speed of the subscriber control processor.
종래에는 가입자 제어 프로세서가 링 릴레이 구동 데이터와 링 릴레이 복구 데이터를 직접적으로 가입자 보드에 출력해 주었으나, 본 발명에서는 가입자 제어 프로세서의 링 스타트 명령 데이터에 의해 마이크로-컨트롤러가 자동적으로 링 릴레이 구동 데이터와 링 릴레이 복구 데이터를 소정 주기에 따라 가입자 보드에 출력하는 구조로 구성되어 있으므로 가입자 제어 프로세서의 부하를 감소시켜 가입자 제어 프로세서의 제어 처리 속도를 향상시키게 된다.Conventionally, the subscriber control processor directly outputs the ring relay driving data and the ring relay recovery data to the subscriber board. However, in the present invention, the micro-controller is automatically connected to the ring relay driving data by the ring start command data of the subscriber control processor. Since the ring relay recovery data is output to the subscriber board according to a predetermined period, the load of the subscriber control processor is reduced, thereby improving the control processing speed of the subscriber control processor.
