Near stage mobile foundation 1 from an initial position start along shortest path move to testing transformer 14 very close to certain position, this position measures distance to the distance of testing transformer 14 less than the maximum of infrared sensor 15 used, and in the side of testing transformer 14 connector, the position of this phase measuring platform describes under global coordinate system, and positional information is determined by ultrasonic positioning system.
The docking stage: two infrared sensors 15 gather and the pitch information of reflector 16 that matches on testing transformer 14 respectively, as shown in Figure 2, by coordinate transform, mobile foundation 1 place is transformed to local coordinate system near the coordinate put from global coordinate system, at this moment the position of mobile foundation 1 describes under a local coordinate system, mobile foundation 1 is by a pair infrared sensor 15, the relative position of it and testing transformer 14 is determined by trigonometry, and Automated Design movement locus, adjust the relative position with testing transformer 14, make finally to achieve a butt joint with testing transformer 14.
The docking facilities of mobile foundation 1 is to be made up of two infrared reflector 16 being arranged on testing transformer 14 and two infrared sensors 15 being arranged on mobile foundation 1 front end.The two infrared sensor 15 can rotate under the driving of motor and each sensor includes an infrared emission and an infrared receiving module.Concrete principle is that infrared sensor 15 forwards sends a infrared beam the thinnest, if infrared reflector 16 encountered in perceived distance by this infrared beam, infrared light reflection will return sensor, and by sensor one high level of output or low level.In order to realize positioning function, place two and infrared sensor 15 level column type reflector 16 in the both sides, lower section of testing transformer 14 junction point.During docking, when reflector 16 on the infrared light testing transformer 14 that the infrared sensor 15 on mobile foundation 1 sends, will be reflected back, the angle turned over according to infrared sensor 15 just can determine that the relative position of mobile foundation 1 and testing transformer 14, drive the motor of infrared sensor 15 by AVR single chip control (or being uniformly controlled by controller), the output level of sensor also enters in single-chip microcomputer, and single-chip microcomputer carries out communication by serial ports and main frame.
As in figure 2 it is shown, location algorithm is as follows:
In docking operation, the position of mobile foundation 1 is described by local coordinate system, and this coordinate system is with the midpoint of two reflector 16 lines on testing transformer 14 as initial point, with the line of two reflectors 16 as x-axis.Allowing two infrared sensors 15 start from the direction being parallel to two sensors line to rotate respectively, when reflector 16 being detected, will export a high level, single-chip microcomputer can calculate the angle [alpha] now driving the motor of sensor to turn over respectively1, α2, β1, β2。
According to the most profound theorem, in Δ ABC,
,
In like manner, in Δ BCD,
According to the cosine law, in Δ ABC,
By the most various size obtaining γ, then angle θ=γ-(180 ° of-α2)
Docking stage concrete steps, mobile foundation 1 positions with infrared sensor 15 again, and judge whether it meets corresponding docking condition with the relative position of testing transformer 14, whether the i.e. centrage of mobile foundation 1 meets error condition with the distance of the intersection point of x-axis to initial point, if meeting condition just to dock, otherwise mobile foundation 1 repeats work when this state starts again after rotating in place a angle the least, until it meets docking condition with the relative position of testing transformer 14.Concrete steps are as shown in Figure 3；
1) mobile foundation 1 is rotated in place, such as Fig. 3 (b), when mobile foundation 1 makes the line of infrared sensor 15 on mobile foundation 1 vertical with the line of reflector 16 on testing transformer 14；
2) run forward mobile foundation 1, such as Fig. 3 (c), make infrared sensor 15 line extended line on mobile foundation 1 pass the reflector 16 of first process；
3) rotate in place mobile foundation 1, such as Fig. 3 (d), make spacing between two infrared sensors 15 with two reflectors 16 identical；
4) run forward mobile foundation 1, such as Fig. 3 (d), make spacing between two infrared sensors 15 and two reflectors 16 reach preset pitch value；
Alignment procedures terminates.
