Locomotive general traction control device and control method thereof

The invention relates to a locomotive traction control device, in particular to a locomotive general traction control device and a control method thereof, and solves the problem that an existing traction control device is poor in universality. The device comprises a control board card, a communication board card, a signal input and output board card and a power supply board card. The control boardcard is divided into a master control board and a slave control board. The communication board card is a network interface board; the signal input and output board card is divided into an analog input and output board, an analog-to-digital processing board, a digital input board, a digital output board and a pulse input and output board. Communication of the traction control device is divided into an internal part and an external part. As for the external part, MVB bus communication is adopted between the traction control device and the TCMS; as for the internal part, communication of the TCUinternal boar cards is pe
