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.
Description
technical field [0001] The present application relates to the technical field of railway signals, in particular to a semi-automatic blocking circuit and a driving method for the semi-automatic blocking circuit. Background technique [0002] The so-called double-track semi-automatic block in the railway section, also called 64F semi-automatic block, refers to a block method in which two stations are driven separately through the uplink and downlink lines. Only one train is allowed to pass between the two stations. When the traffic volume of double-track railway lines has not yet reached the requirements of automatic blocking, such as: local railways, non-busy main lines, etc., the 64F semi-automatic blocking method is still widely used. [0003] figure 1 Schematically shows the interaction diagram of each device in the station, see figure 1 As shown, the safety host 101 such as the computer interlocking system or train control and interlocking integrated system of the stat...
