The invention discloses a system for expelling social vehicles from a special lane of substation engineering. The system comprises a main control central system and sub-control central systems, wherein the sub-control central systems are used for summarizing information in a monitored area and used for transferring the information to the main control central system, so as to assist in completing tasks of an expelling system; the main control central system is connected with different sub-control central systems through network IP control; the main control central system is further connected with a police information network. Under the condition that partitioning piles are not added, license numbers are recognized by using cameras, and drivers can be reminded of driving off the special lane immediately in modes of voice, electronic display screens and the like; moreover, as the system is connected with the policy information network, when the social vehicles park is overtime, a policy system can assign road wreckers to drag off the illegal vehicles, the social vehicles that park illegally can be recognized, alarmed and expelled, and thus a door of a substation is not blocked.
