the multiple interlocking control mode is an interlocking relation jointly determined by a signal machine, a track circuit, turnouts, locomotive models and line types.
5. The locomotive routing access system for preventing electric locomotives from running through a wireless network area according to claim 4, wherein if the locomotive is a diesel locomotive traction, the admission command is selected; the method specifically comprises the following steps:
acquiring identity information of an operator, and verifying the identity information; the identity information verification comprises password verification;
if the identity information passes the verification, judging whether the route selected last time is: if not, carrying out inconsistent prompting; if yes, entering a route selection and arrangement process.
