80%, it is to start speed (1-0 meters) when transverse-moving trolley 6 is back to original position, the frequency for presetting walking frequency converter is specified
20%.
The speed of travel of the transverse-moving trolley 6 in start-up course is starts speed, and walking process is normal speed, by base process
To lean on base speed, return course is high speed return speed, and transverse-moving trolley 6 is different in the average speed of different motion process, in advance
The average speed of each motion process is calculated, i.e., averagely starts speed, the average speed of travel, averagely lean on base speed and average return
Speed.Since transverse-moving trolley 6 is different in the run time of different motion process, velocity variations are also different, for example, in start-up course
Velocity variations are larger, smaller in walking process velocity variations, and therefore, setting is corresponding respectively averagely starts speed, average row walking speed
Degree, the length for averagely leaning on base speed and the acquisition time section of average return speed, for example, setting is corresponded to averagely by base speed, put down

State, for example, then judging that transverse-moving trolley 6 be in walking states, selection closest to the average speed of travel according to, instantaneous movement speed
The corresponding acquisition time section of the average speed of travel calculates the real-time displacement distance of transverse-moving trolley 6.
In the present embodiment, the acquisition time section of walking process is preset as 100ms, then calculates primary shifting in real time every 100ms

S1=100/60000*V1
S2=100/60000*V2
S3=100/60000*V3
…
Sn=100/60000*Vn (2)
Multiple real-time displacement distances are obtained according to formula (2)：S1, S2, S3 ..., Sn.
Step S140：The sum of the real-time displacement distance in whole acquisition time sections is calculated, the movement for obtaining transverse-moving trolley is total
Distance.
Specifically, if acquisition time section is walking process, the calculation formula for moving total distance is：
L=S1+S2+S3+ ...+Sn (3)
If acquisition time section further includes other motion processes, such as start-up course, then when calculating mobile total distance L, also need
The real-time displacement distance of acquisition time section is each acquired in cumulative start-up course.
Since each rear portion roller-way and the distance for being heat-fed roller-way 4 are fixed, so the continuous casting on the roller-way of each rear portion
The distance of base to hot sending roller-way 4 is changeless, thus calculate real-time displacement distance and can obtain transverse-moving trolley 6
To the distance each flowed
Further, according to mobile total distance and the difference of pre-determined distance, control transverse-moving trolley 6 moves.Specially：According to
Mobile total distance is less than pre-determined distance, and control transverse-moving trolley 6 advances；Pre-determined distance is less than according to mobile total distance, control is traversing
