The invention provides a switch split monitoring device, comprising a calculating unit. A first input port of the calculating unit is connected to a positioning signal port of a point switch; a second input port of the calculating unit is connected to an anti-position signal port of the point switch; the calculating unit is also provided with at least another input port to be connected with at least one wheel sensor which is arranged on the outer side of a switch at a certain distance. Based on the device, the invention also provides a switch split monitoring method. Early warning for switch split can be given, and occurrence of switch split can be prevented. In addition, wiring of an existing line is not modified when the position of the switch is detected. Further, double sensors are arranged, so that the false alarm probability is reduced.
