Matrix unlocking circuit with feedback signal identification
The invention provides a matrix unlocking circuit with feedback signal identification. The matrix unlocking circuit with feedback signal identification comprises the following components of: 1) an MCU(Micro Control Unit) which comprises at least three groups of IO ports; 2) an I/O column level conversion circuit; 3) an I/O row-column level conversion circuit; 4) an electric control lock and a diode; 5) a lock matrix power line switch MOS tube circuit; 6) a lock matrix ground wire switch MOS tube circuit; and 7) a lock feedback level conversion circuit. According to the technical scheme of thematrix unlocking circuit with feedback signal identification, the number of 2N*M I/O ports required by unlocking control and feedback of a traditional grid cabinet with N (row)*M (column) small doorscan be reduced to 2N+M I/O ports.
本发明提供了一种带有反馈信号识别的矩阵开锁电路，包括：1)MCU(Micro Controller Unit，微控制单元)，包含至少3组IO口；2)I/O纵列电平转换电路；3)I/O行列电平转换电路；4)电控锁和二极管；5)锁矩阵电源线开关MOS管电路；6)锁矩阵接地线开关MOS管电路；7)锁反馈电平转换电路。本技术方案可以将传统有N(行)*M(列)个小门的格子柜控制开锁和反馈所需的2N*M个I/O口数量，减少为2N+M个I/O口数量。
