Further, the size of each driving wheel can rationally be set according to practical application request as shown in Figure 2, the influence of its size
Speed, general size gets over that slight drag is smaller, and moment of torsion is bigger, so driving force is stronger, but speed is slower.
Swash width self calibration principle of the present invention is described as follows：
With reference to Fig. 2, in actual applications, it is assumed that need to measure arrow position number of coordinates when rocket body injects archery target 17
According to, in order to improve the precision and reliability of measurement, therefore need select a reference value, can for example select refer to such as institute in Fig. 2
The unidirectional movement of total travel is once obtained any one passive scanning head of the control of active drive wheel 12 on side where it in the system shown
The formula arrived：
Dsize=Ls/Nstep (1)
Assuming that the radius of active drive wheel is R, in theory, active drive wheel is often rotated/taken a step forward, corresponding probe
Mobile distance is：
Dsize=2 π R Φ (2)
Wherein, DsizeThe distance that probe is moved when often rotating/take a step forward when being controlled for active driving wheel 12, that is, scan
Step-length, that is to say the stepping-in amount parameter of active drive wheel 12, LsFor the distance between two limiters, NstepFor active driving wheel
12 control probes sequentially pass through the step number advanced during two limiters, and R is the radius of active driving wheel 12, and Φ is active drive
Wheel 12 often rotates/taken a step forward rotated angle.
Formula (2) is substituted into can draw in formula (1)：
Ls=2 π R Φ * Nstep (3)
It can be seen from formula (3) when without using limiter proposed by the present invention, passive scanning head is where it on side
The unidirectional displacement L of total travel would generally be subjected to the influence of the conditions such as ambient temperature and cause active drive wheel radius
Change or the elastic change of coiling, cause its numerical measuring error larger, and manufacturing process due to active drive wheel 12 and
Product batches etc. influence, and the distance i.e. scanning step that will equally cause each stepping and the distance for often enclosing stepping are inconsistent,
Therefore a series of accumulated error (open error) will be produced, ultimately result in unreliable, the error of arrow position measurement result
It is larger or even invalid.The present invention proposes the design using start point/end point limiter, in passive scanning head where it full row on side
Cheng Danxiang displacements (L) two-end-point introduces position restriction detection, and for calibrating or extrapolating Dsize, and then can be by two
The distance between limiter Ls(as shown in Fig. 2 when two limiters are arranged on the swash width two-end-point of passive scanning head, Ls
=L) between any error be defined to the error of a closing, therefore can accurately determine that for example active drive wheel 12 is every
The distance that step the is advanced reference value such as be how many, therefore and then can real-time implementation swash width progress self calibration (is swept to passive
Retouch the unidirectional displacement L of a total travel and carry out self calibration), to correct at any time due to expanding with heat and contract with cold or the outside cause such as coiling is elastic
The change of caused scanning step, it is ensured that measurement accuracy under circumstances.
