A rail inspection trolley running direction calculation method, system and computer

Abstract

The application provides a track inspection trolley running direction calculation method, system and computer, the track inspection trolley running direction calculation method comprises the following steps: receiving the positioning data of track inspection trolley in time period as a unit cycle, forming several positioning data groups;According to the positioning data group of the nearest time period, the action state of track inspection trolley is determined;If the track inspection trolley is in a stationary state, the positioning data group of the previous time period is gradually extracted until the track inspection trolley is determined to be in a running state;According to the positioning data group when the track inspection trolley is in a running state, the running direction angle of the track inspection trolley is obtained.The average positioning accuracy and average distance of the positioning data group are calculated to determine the action state of the trolley, to avoid the problem of large direction angle deviation caused by false position changes of the trolley due to positioning data accuracy in a stationary state, and to calculate the direction angle using the positioning data group of the track inspection trolley in a running state, which has smaller deviation and is more accurate, facilitating subsequent detection work of the track inspection trolley.
