Foreign matter expelling method and system

The invention discloses a foreign matter driving method and system, the method is applied to the foreign matter driving system, the system comprises at least one holder and a scheduling service center, and each holder comprises a sensing subsystem and a driving subsystem. The method comprises the following steps: performing data fusion on sensor data of a target foreign matter through a sensing subsystem of at least one holder to obtain target sensing information, and sending the target sensing information to a scheduling service center; and the dispatching service center issues a target driving instruction to a target holder based on the target sensing information, so that a driving subsystem of the target holder drives the target foreign matter, and the target driving instruction is obtained by performing joint decision analysis based on the target sensing information. According to the method, intelligent sensing and analysis of the foreign matters are realized, and an information basis is provided for subs
