And when the server receives the GPS data reported by the vehicle equipment, starting an ignition monitoring process corresponding to the vehicle, and carrying out time verification on each recorded packet of the GPS data through the ignition monitoring process. The time check is used for judging whether each packet of the GPS data is in a continuous reporting state, if the GPS data of each packet is continuous, the current state of the vehicle is determined to be running and stable, and if the continuous GPS data starts to have discontinuous characteristics, the current state of the vehicle is determined to be flameout or unstable. Optionally, the time check mode may be determination of reporting time intervals of front and rear GPS data, or a distribution state of reporting time of each GPS data.
In this embodiment, after the time check is performed on each recorded packet of the GPS data by the ignition monitoring process, each packet of the GPS data that passes the time check is written into the ignition monitoring queue. Likewise, a fire listening queue corresponding to the current vehicle is created or started by the server, and optionally, a fire listening queue process corresponding to the current vehicle is created or started in the fire listening queue program. Then, writing each packet of the GPS data passing the time check into an ignition monitoring queue.
