Zusammenfassung:	The invention discloses a vehicle derailment early warning method and device. The method comprises the steps that a derailment early warning model is established based on historical displacement data of a sampling machine trolley and historical displacement data of a sampling machine cart; determining derailment risk levels of the sampling machine trolley and the sampling machine cart based on the model; when the derailment risk level is not in a low risk level, the derailment condition of the sampling machine trolley or the sampling machine cart is recognized in real time based on the wheel vibration signals of the sampling machine trolley and the sampling machine cart and based on the vibration signals; when it is recognized that the sampling machine trolley or the sampling machine cart is in a derailment state, an alarm signal is sent; and a safety isolation area is established based on the derailment condition of the sampling machine trolley or the sampling machine cart, so that timely early warning of th
