Cross MVB to send to the MVB/CAN modules (16), pass through again after carrying out protocol conversion by the MVB/CAN modules (16)
CAN sends to the traveling display of the CAN network control module (15) and shown.
10. railway engineering machine power control method according to claim 9, it is characterised in that the dynamical system is also
Switched including emergency excitation, the emergency excitation is switched and is connected by hardwired fashion with the excitation con-trol module (13), will
The emergency excitation switch is placed in emergent position to enter emergency excitation control process, and the process comprises the following steps：
Under emergency excitation control model, the high level of the emergent control port processing of the excitation con-trol module (13) to setting
Signal value, the excitation con-trol module (13) are not responding to the magnitude of voltage (V1) given by the MVB, and directly control described
Output voltage of the output of generator (12) after AC/DC modules (22) rectification is the DC voltage value of setting.
