Train switching value determination method, vehicle-mounted signal system, train and electronic equipment

The invention provides a train switching value determination method, a vehicle-mounted signal system, a train and electronic equipment, and the method comprises the steps: obtaining a switching value configuration table through a mode of reading application layer configuration; determining input switching value information corresponding to the first contact information based on a switching value configuration table; and/or determining second contact information corresponding to the output switching value information based on the switching value configuration table; the switching value configuration table is used for representing the corresponding relation between each switching value of the train and each contact of the input and output board card, the first contact information is used for representing the state of an input contact of the input and output board card, and the second contact information is used for controlling the state of an output contact of the input and output board card.
