Abstract

본 발명의 보드의 탈장 감시회로는 메인 보드의 슬롯에 장착된 다수의 보드에서 탈장된 보드를 정확하게 검출하는 것이다.The hernia monitoring circuit of the board of the present invention accurately detects a hernia board in a plurality of boards mounted in a slot of the main board.

본 발명은 온도 및 습도의 변화나 잡음 등에 거의 영향을 받지 않고, 항상 일정한 정전압을 유지하는 정전압 다이오드를 이용하는 것으로서 다수의 저항(R₁₀,R₁₁,R₁₂,R₁₃)을 직렬 연결함은 물론 첫번째 저항(R₁₀)을 제외한 나머지 저항(R₁₁,R₁₂,R₁₃)에 정전압 다이오드(ZD₁₁)(ZD₁₂)(ZD₁₃)를 각기 병렬로 연결하고, 저항(R₁₁,R₁₂,R₁₃) 및 정전압 다이오드(ZD₁₁)(ZD₁₂)(ZD₁₃)의 각각의 접속점을 슬롯의 접속단자(CN₁₁₁,CN₁₁₂)(CN₂₁₁,CN₂₁₂)(CN₃₁₁,CN₃₁₂)에 접속하여 슬롯에 보드(11,12,13)를 장착할 경우에 접속단자(CN₁₁₁,CN₁₁₂)(CN₂₁₁,CN₂₁₂)(CN₃₁₁,CN₃₁₂)가 접속되게 함으로써 보드(11,12,13)의 탈장시 탈장 검출점(CON₁₁)의 전압이 정전압 다이오드(ZD₁₁)(ZD₁₂)(ZD₁₃)의 정전압에 따라 정확하게 가변되어 탈장된 보드(11,12,13)를 정확하게 검출할 수 있다.The present invention uses a constant voltage diode that is almost unaffected by changes in temperature and humidity, noise, etc., and always maintains a constant constant voltage, as well as connecting a plurality of resistors R ₁₀ , R ₁₁ , R ₁₂ , and R ₁₃ in series. A constant voltage diode (ZD ₁₁ ) (ZD ₁₂ ) (ZD ₁₃ ) is connected in parallel to the remaining resistors R ₁₁ , R ₁₂ , and R ₁₃ except the first resistor (R ₁₀ ), and the resistors R ₁₁ , R ₁₂ , Connect each connection point of R ₁₃ ) and constant voltage diodes ZD ₁₁ (ZD ₁₂ ) (ZD ₁₃ ) to connection terminals CN ₁₁₁ and CN ₁₁₂ of the slot (CN ₂₁₁ and CN ₂₁₂ ) (CN ₃₁₁ and CN ₃₁₂ ). Board (11, 12, 13) by connecting the connection terminals (CN ₁₁₁ , CN ₁₁₂ ) (CN ₂₁₁ , CN ₂₁₂ ) (CN ₃₁₁ , CN ₃₁₂ ) ), The voltage at the hernia detection point (CON ₁₁ ) is accurately varied according to the constant voltages of the constant voltage diodes (ZD ₁₁ ) (ZD ₁₂ ) (ZD ₁₃ ) to accurately detect the hernia boards (11, 12, 13). have.
