J =: = ;: r, which means that the present invention can reduce the number of parts, and 1240067 can reduce the manufacturing cost. When the number is reduced, the man-hours for assembly can also be reduced during assembly, and the accuracy of assembly can be increased. The above-mentioned multiple sensing areas can be distributed on the rim flanges of the front wheel or the rear wheel of the locomotive at equal angles, and the counting sensor can use 5 general optical sensors in addition to electromagnetic sensors. Perceptron, or other equivalent perceptron. [Embodiment] First, please refer to FIG. 5 for a side view 10 of the first preferred embodiment of the present invention and FIG. 6 for a cross-sectional view of FIG. 5. A rear wheel n of a locomotive is shown, and the rear wheel 11 includes A rim 111, a tire 113, and a central rotating shaft 10, and at the same time, the rim 111 of the rear wheel 11 includes a rim flange portion 112 on each of its two sides, and the two rim flange portions 112 face the locomotive respectively. When the rear side 11 is rotated around the center rotation axis 10 as the center, the second rim flange portion 15 112 can rotate coaxially with subsequent rotation of the wheel ill at the same time. In addition, 'on one of the rim flange portions 112 of the rim 111 of the rear wheel 11 of the locomotive', a plurality of sensing zones 2 are distributed at equal angles such as concentric circles, and in the present embodiment, 'the rims are directly on the rim flanges. A plurality of through-holes are penetrated through the portion 112 to form a plurality of other sensing regions 2. At the same time, in this embodiment, the shape of the above-mentioned through-holes are circular holes. Of course, quadrangular holes and pentagonal holes can also be used. , Or polygonal holes. In addition, a counting sensor 3 is arranged on the rear wheel rocker arm 14 of one of the rear wheels 11 of the locomotive. The counting sensor 3 is an optical sensor in this embodiment. The counting sensor 3 corresponds to the rear wheel 11 of the locomotive. One of the plurality of sensing areas 2 above is 1240065, and it can be opposed to the plurality of sensing area counting sensors 3 to maintain a specific distance. At the same time, the flange portion m directly senses the rear wheel of the locomotive η, its rim sensing area 2. In the autumn, two: the plurality of optical sensing n-shirts formed by a plurality of hard through holes are limited to the devices used in this embodiment. Others such as electromagnetic sensors, or other equivalent perceptions, therefore, 'when the locomotive is traveling, the coaxial wheel P follows from the rim 111 and the coaxial flange 112 follows the wheel 11 at the same time. Turn ίο 15 in the following round 11 and _, = two 1 perforated multiple sensing zones 2 also know 4 and _, keep together, the counting sensor 3 can correspondingly detect and two t zone 2 passes the counting sensor 3 'That is, the perceptron ⑽ of the rim 2 of the rim 2 / the rotation of the rim flange 112 of the wheel 11 passes through the induction mx to calculate the speed of the locomotive rear wheel 11 at that time, thereby achieving the purpose of locomotive speed detection. From the above, it can be known that the plurality of sensing areas 2 are directly on the rim flange portion 112 of the locomotive rear wheel 11 at the same angle as the concentric circles. This can avoid the traditional design method of adding additional components, that is, by the above structure It can really reduce the number of ft ', which can relatively reduce the manufacturing cost, and because the number of parts is reduced, the assembly time can also be reduced in the group, and the accuracy of the assembly can be increased. Fig. 7 is a side view of the second preferred embodiment of the present invention and Fig. 8 is a cross-sectional view of Fig. 7. The main structure is the same as that of the first preferred embodiment except that a plurality of sensing regions are different. The 5 series directly attaches concentric circles and equal angles to the rim flange portion 122 of the rim 121 of the front wheel of the locomotive, and the counting sensor 4 is arranged on the shock absorber 13 of one of the front wheels 12 of the locomotive. 20 1240065 and corresponding to the plurality of sensors 4 are corresponding to the plurality of sensing areas 5 and the sensing areas 5 are maintained between each other-a specific distance is similar to the plurality of sensing through holes and counting the residual holes:; in this embodiment These are the main components of this article. When the locomotive has been driving rich, that is, its front wheel 12J ^ learns the heart and rotates, the front center axis 20 is the axle wheel 12 rim convex. The bismuth on the edge 122 and your deer are following the coaxial rotation, and here are the same as the multiple sensing areas 5

Then, the locomotive emperor count sensor 4 and the plurality of sensing areas 5 are implemented in this embodiment, although they are placed on the front wheel 12 ±, but they can also achieve the various effects described in the first-comparative embodiment. Please refer to Fig. 9 which is a three-dimensional 15 2 of a wheel rim according to a third preferred embodiment of the present invention, in which a plurality of sensing regions are shown. It is a bump, which is different from the perforations used in the plurality of sensing areas 2, 5 described in the first and second preferred embodiments, but such a design does not affect its counting function. Fig. 10 is a side view of the fourth preferred embodiment of the present invention. The main structure is the same as the first preferred embodiment, except that the plurality of 20 sensing areas 812 are directly connected to the rear wheels 81 of the locomotive. It is formed by the ribs on the rim 811. Similarly, when the plurality of sensing areas 812 on the rim 811 rotate coaxially with the rear wheel, the counting sensor 821 is arranged on the rocker arm 82 behind the rear wheel 81. It can correspondingly detect and perceive how many sensing areas 812 pass the counting sensor 821 'and calculate the speed of the locomotive at that time. 1240065 From the above, it can be known that a plurality of sensing areas 2, 5 can be directly formed on the front wheels 12 and the rear wheels of the locomotive. The rim flange portions 122 and 112 of 11 are as described in the first and second preferred embodiments. In addition, a plurality of sensing regions 812 can also be directly formed on the ribs of the rim 811 of the rear wheel 81 of the locomotive. The ribs of the front wheels (type 5 in the figure), but no matter where they are formed, they can also achieve the purpose of locomotive speed detection ', and can also avoid the traditional design method of adding additional components, and can reduce the number of parts and reduce manufacturing costs. ,Less The purpose of reducing assembly man-hours and increasing assembly accuracy.
