The speed zero detection section (7) detects that the output of step 2) is zero, and issues a command to the distance sensor (3) to measure the distance. At the same time, wheel diameter measurement calculation and memory section (f)
Calculation and memory commands are given from the speed zero detection section (W), and the wheel diameter is calculated from the output signal sent from the distance sensor port (W) and stored. The memory section <g> stores the past several wheel diameter calculation values, and each time a new memory is added, one of the most speech memories is erased.
It always stores several new measurements in memory and outputs their average value to the speed detection section with wheel diameter correction calculation. This speed detection part (?) is connected to the speed generator while the vehicle is running.
A speed detection signal is continuously output by multiplying the signal output proportional to the wheel rotation speed by the wheel diameter.

踏面の状況により正確な測距が行われたｂ場合も時たま
起りうるからである。In the correction calculation of the wheel diameter, data from the past several stops are stored and the average value is used because the distance sensor (3) measures the distance (δ) from the wheel tread.
This is because when measuring the wheel (/1 K), it may happen that the measurement is made at a location where uneven wear (flat) due to skidding occurs, or the accurate distance measurement may not be possible due to the condition of the wheel tread. .

いずれにせよ、７回の停車時に／回章輪径を測定すると
いう論理を設けておく。In any case, there is a logic in place to measure the turning wheel diameter when the vehicle stops seven times.

ようにする。The distance sensor (3) can be easily realized by using an ultra-radio range sensor or optical sensor, which is recently used in automatic focusing cameras, etc., but when the vehicle is running, it The vibrations, noise, and lighting conditions fluctuate dramatically, making it difficult to accurately measure distances. Therefore, the distance sensor (3) is activated only when the output of the speed generator (K) is zero, that is, the output pulse is zero, and the result is stored in the speed detector (6). do it like this.

。Figures 1 and 3 show an example of installing the distance sensor (3) using a gear case loaded on the axle (Y). The gearbox (/yu) of the gears connected via the coupling (//) is attached to the axle <k) via the pairing, and one end is attached to the suspension rod (/3) with a cushioning rubber (not shown). It is connected to a trolley (not shown) via a carriage (not shown). The distance sensor (3) is attached to the gear case (/).

ので、格段に精度の高い速度検出が可能となる。As is clear from the above description, this invention constantly checks the wheel diameter and takes the average value of several measurement data. Since it measures the tread surface facing the distance sensor when the vehicle is running, more accurate wheel diameter detection is possible, and the wheel diameter correction selector switch inside the speed detector makes it easier to measure the wheel diameter manually than in the past. Compared to the above case, the correction cycle is shorter and the correction is performed steplessly and continuously, making it possible to detect speed with much higher accuracy.
