The invention provides a semi-automatic blocking circuit and a driving method of the semi-automatic blocking circuit. The semi-automatic blocking circuit comprises a first departure gate circuit; thefirst departure port circuit comprises a first relay, a second relay, a first current direction detection unit, a first power supply positive electricity, a first power supply negative electricity, afirst external connection terminal and a second external connection terminal; a middle contact of the first relay is connected with a first external connection terminal, a front contact of the first relay is connected with first power supply positive electricity, and a rear contact of the first relay is connected with a first end of the first current direction detection unit; a middle contact of the second relay is connected with the second external connection terminal, a front contact of the second relay is connected with the first power supply negative electricity, and a rear contact of thesecond relay is connected with the second end of the first current direction detection unit. An existing traditional relay needing to be wired and installed on site can be omitted, the construction period of a station is shortened, excessive fault points are omitted, and on-site maintenance work is facilitated.
本申请提供一种半自动闭塞电路、半自动闭塞电路的驱动方法,半自动闭塞电路包括:第一发车口电路;第一发车口电路包括:第一继电器、第二继电器、第一电流方向检测单元、第一电源正电、第一电源负电、第一对外连接端子、第二对外连接端子;第一继电器的中接点连接第一对外连接端子,第一继电器的前接点连接第一电源正电,第一继电器的后接点连接第一电流方向检测单元的第一端;第二继电器的中接点连接第二对外连接端子,第二继电器的前接点连接第一电源负电,第二继电器的后接点连接第一电流方向检测单元的第二端。能够取消现有的需要在现场实施配线及安装的传统继电器,减少车站的施工周期,以及取消了过多的故障点,便于现场的维护工作。
