6. The system for deducing the grouping, sequencing and hitching of the catenary working vehicle as claimed in claim 5, wherein in each module, the distance L between two vehicles is calculated by the following method:
acquiring longitude and latitude of the two vehicles, namely (lat1, lng1) and (lat2, lng 2);
L=(2*sin(sqrt(pow(sin(rad(lat1)-rad(lat2)/2),2)+cos(rad(lat1))*cos(rad(lat2))*pow(sin(rad(lng1)-rad(lng2)/2),2))))*6378137.0;
the vehicle speed information v is calculated by the following method:
obtaining a pulse count value count1, a counting time1, a pulse count value count2 and a counting time 2; a single pulse distance dis;
v=((count2-count1)*dis)/(time2-time1)。
