Abstract
본 발명은 엘리베이터에 관한 것으로서, 특히 엘리베이터 위치를 나타내는 7세그먼트 LED을 점등시키는 연결선을 줄이고, 층 표시 문자 형태를 변경할 수 있도록 한 엘리베이터 위치표시 제어회로에 관한 것이다. 종래기술에 따른 엘리베이터 위치표시 제어회로는 각 LED 세그먼트 단자에 제어부(10)의 출력을 직접 연결하여 구동시킴으로써, 연결선이 많아지고 쉽게 층 표시를 현장에서 할 수 없는 문제점이 있다. 또한, 배선수가 많아 오결선이 많이 발생됨에 따라 엘리베이터의 잦은 고장이 발생되는 문제점이 있다. 따라서, 본 발명에 따른 엘리베이터 위치표시 제어회로는 상기한 종래에 따른 문제점을 해결하기 위한 것으로, 사용자가 원하는 층 부름 신호가 입력 인터페이스부를 통해 메모리부에 입력됨과 동시에 층 연산을 수행하여 현재 층을 인식하여 LED 세그먼트 출력 인터페이스부로 출력하는 제어부와, 상기 제어부에서 4비트 층 코드와 입력 허락 신호를 입력받는 다수개의 4비트 레지스터와, 상기 다수개의 4비트 레지스터부에서 4비트 신호를 입력받아 7,9 세그먼트 신호로 변환시키는 다수개의 PAL 및 GAL부와, 상기 다수개의 PAL 및 GAL부에 입력된 7,9 세그먼트를 출력하는 LED 세그먼트 구동부와, 상기 LED 세그먼트 구동부에 의해 발광되는 7,9 세그먼트부를 포함하여 이루어지고, 배선 수를 대폭적으로 줄일 수 있으며, 적은 선수로 충분히 제어부의 코드를 7,9 세그먼트로 변환하여 엘리베이터의 위치를 표시하는 엘리베이터의 위치표시 제어회로에 유용하게 적용되는 이점이 있다.The present invention relates to an elevator, and more particularly, to an elevator position display control circuit for reducing a connecting line for illuminating a 7-segment LED indicating an elevator position and changing a layer display character shape. The elevator position display control circuit according to the related art has a problem in that the output of the control unit 10 is directly connected to each LED segment terminal and driven so that the number of connecting lines increases and the floor display can not be easily performed on the spot. Further, since a large number of wires are formed and a lot of erroneous wires are generated, frequent failures of the elevator may occur. Accordingly, the elevator position display control circuit according to the present invention solves the above-described problem in the related art, and a floor calling signal desired by the user is input to the memory unit through the input interface unit, And a plurality of 4-bit registers for receiving a 4-bit layer code and an input permission signal from the control unit, and a 4-bit register for receiving the 4-bit signal from the 4-bit register unit, A plurality of PAL and GAL units for converting a plurality of PAL and GAL units into a plurality of PAL and GAL units, and a 7,9 segment unit for outputting 7,9 segments input to the plurality of PAL and GAL units, And the number of wiring can be greatly reduced, Is converted into the fragment has the advantage to be usefully applied to the display position control circuit of the elevator to display the position of the elevator.
