본 발명은 변전소 운영상태 감시를 위한 디지탈 축소형 모자익 배전반의 마스터 CPU 이중화구조에 관한 것으로서, 특히 마스터CPU의 메인CPU수단이 고장났을때에도 이중화구조를 갖는 보조CPU수단이 그 즉시 메인CPU수단의 기능을 대체함에 따라 전체적인 모자이크시스템의 작동이 원활히 이루어져 변전소 운영상태를 정상적으로 모니터링할 수 있도록 한 변전소 운영상태 감시를 위한 디지탈 축소형 모자익 배전반의 마스터 CPU 이중화구조에 관한 것이다.The present invention relates to a duplication structure of a master CPU of a digital miniature mosaic switchboard for monitoring substation operation status, and more particularly, even when a main CPU unit of a master CPU fails, a secondary CPU unit having a redundant structure immediately performs functions The present invention relates to a duplication structure of a master CPU of a digital miniature mosaic switchboard for monitoring the operation status of a substation so that the entire mosaic system can be smoothly operated and the substation operation status can be normally monitored.

일반적으로 각 가정이나 사무실 등에서 사용되는 전기는 각 지역별로 설비되어 있는 변전소로부터 제공되고 있다. Generally, electricity used in each home or office is provided from a substation equipped for each region.

즉, 변전소는 발전소에서 생산한 전력을 송전선로나 배전선로를 통하여 수용가에게 보내는 과정에서 전압이나 전류의 변성 및 전력의 배분을 위하여 설치되는 시설이라 할 수 있으며, 상기 변전소는 154KV, 23KV용 현장설비로 나뉘어지며, 23KV 변전소를 통해 각 부하(소비자)로 전기가 공급된다.That is, the substation is a facility installed for the modification of voltage or current and the distribution of electric power in the process of sending electric power generated by a power plant to a customer through a transmission line or a distribution line, and the substation is a facility for 154KV and 23KV The electricity is supplied to each load (consumer) through a 23 KV substation.

그리고, 각각의 변전소에는 부하측으로 전기를 공급하는 도중 단락이나 지락상태일때 시설물을 보호하기 위하여 전선로를 차단하는 복수개의 차단기가 설치된 다.In addition, each substation is equipped with a plurality of circuit breakers which cut off the power line to protect the facility when a short circuit or a ground fault occurs during the supply of electricity to the load side.

상기 설명과같이 변전소에는 수용가로 전기를 안정적으로 공급하기 위한 아주 복잡한 설비가 갖추어지게되며, 이러한 변전소에 설치된 차단기와 같은 각종 장치의 동작상태를 모니터링하여 고장의 징후를 미리 발견하여 대비하거나 아니면 발생된 고장에 신속히 대응하여 복구할 수 있도록 모니터링시스템이 제공되고 있다.As described above, the substation is equipped with a very complicated equipment for stably supplying electricity to the customer. By monitoring the operation status of various devices such as a circuit breaker installed in the substation, Monitoring systems are being provided to allow quick response to faults and recover.

종래의 모니터링시스템은 현장기기, 즉, 현장에 설치된 각종 차단기 및 그밖의 장치들과 메인관리시스템을 각각 독립적인 케이블로 연결하여 메인관리시스템에서 변전소의 현장기기 동작상태를 모니터링하도록 구성되어 있다.The conventional monitoring system is configured to monitor the operation status of the field devices of the substation in the main management system by connecting the field devices, that is, the various breakers installed in the field, and the other devices and the main management system with independent cables.

그러나, 종래에는 모니터링시스템의 전체적인 모니터링동작을 제어하는 마스터CPU가 하나의 CPU에 의해 구현되므로 CPU가 고장났을때 모니터링시스템 전체가 정상적인 작동이 불가능해지는 문제점이 있었고, 이로인해 마스터 CPU의 고장에 따른 모니터링시스템이 정지하게되어 변전소의 제어가 어려워져 대형 정전사고가 발생하게되는 문제점이 있었다.However, in the related art, since the master CPU for controlling the overall monitoring operation of the monitoring system is implemented by a single CPU, there is a problem that when the CPU is broken, the entire monitoring system becomes impossible to operate normally. The system is stopped and the substation control becomes difficult, resulting in a large power failure.

따라서, 상기 문제점을 해결하기 위한 본 발명은 통신라인과 연결되어 RS-485방식으로 데이타를 송수신하며, 현장정보처리반과 모자이크장치의 램프제어모듈 및 스위치제어모듈이 정상적으로 데이타를 교신할 수 있도록 데이타의 송수신 어드레스를 지정해주는 모자이크장치의 마스터CPU를 메인CPU수단과 보조CPU수단의 이중 화구조를 갖도록 하고, 현재 작동중인 메인CPU수단의 작동상태를 감시하는 콘트롤수단에 의해 메인CPU수단에 이상이 발생했을때 자동으로 보조CPU수단이 작동하도록 구성하므로서, 마스터CPU의 메인CPU수단이 고장났을때에도 이중화구조를 갖는 보조CPU수단이 그 즉시 메인CPU수단의 기능을 대체함에 따라 전체적인 모자이크시스템의 작동이 원활히 이루어져 변전소 운영상태를 정상적으로 모니터링할 수 있도록 한 변전소 운영상태 감시를 위한 디지탈 축소형 모자익 배전반의 마스터 CPU 이중화구조를 제공함을 목적으로 한다.In order to solve the above-described problems, the present invention provides a data communication system, which is connected to a communication line and transmits and receives data in an RS-485 manner, and controls a lamp control module and a switch control module of a mosaic device, The master CPU of the mosaic device designating the sending / receiving address has a redundancy structure of the main CPU means and the auxiliary CPU means and an abnormality has occurred in the main CPU means by the control means for monitoring the operating state of the main CPU means currently operating Even when the main CPU means of the master CPU malfunctions, the auxiliary CPU means having the redundant structure immediately replaces the function of the main CPU means, so that the entire mosaic system is smoothly operated, Operation status of a substation for normal monitoring of operation status The master CPU redundancy of the digital reduced mosaic distribution board for the city in order to provide.
