| description | The invention discloses a vehicle bearing damage early warning method based on frequency converter current detection, and the method comprises the steps: obtaining the real-time state parameters of a vehicle at regular time, comparing the real-time state parameters with the state parameter range of the normal state of the vehicle, and judging the state of the vehicle; a detection time period and a time period are set, far and near side current parameters of the bearing in each time period are obtained through a frequency converter, a current difference value in the same time period is calculated, the current difference value is compared with a set current difference value threshold value, whether the current is within the current difference value threshold value or not is judged, and an alarm is given according to a judgment result. The frequency converter current is used for detecting vehicle bearing damage and early warning, bearing damage can be judged in advance, secondary damage can be avoided, rail abra |
