Interface cabinet fixing method based on computer interlocking, and interlocking system

An embodiment of the invention discloses an interface cabinet fixing method based on computer interlocking, and an interlocking system. A correspondence between the terminals of each connector which is connected with a combined cabinet and terminals of connectors that are connected with an interlocking cabinet is established in reference to the available terminals of an interlocking input/output board. The correspondence is represented and connection is realized in a manner of printed circuit board. The interface cabinet fixing method has advantages of reducing wiring assembling errors caused by number increase of wirings of a cascaded cabinet or interface cabinet performed for realizing institutionalization, sequencing and standardization, reducing a fault rate and improving operation safety of a train.
