The invention discloses a vehicle-mounted terminal working state monitoring method, device and system. The method comprises the steps that positioning information reported by vehicle-mounted terminals arranged in a number of driving vehicles is received; for each vehicle-mounted terminal, when received positioning information continuously reported by the vehicle-mounted terminal is interrupted, a next target monitoring site to be passed by the vehicle is predicted according to the latest received positioning information; in received image information, which are acquired by video monitoring devices arranged in all monitoring sites, of all vehicles, whether the image information, which is recorded by the target monitoring site, of the vehicle exists is searched; if the image information exists, the working state of the vehicle-mounted terminal is identified to be abnormal; and the identified abnormal working state of the vehicle-mounted terminal is fed back to a monitoring terminal and is displayed. According to the scheme of the invention, whether the vehicle-mounted terminal of a driving vehicle is in a normal working state can be accurately determined.
