This method of data analysis is convenient for professionals, but for beginners, it is difficult to understand and difficult to experimentally correct the intelligent vehicle control, and there is a lack of intuitive display methods.

[0007] The purpose and effect of the intelligent vehicle control experimental device that can be intuitively demonstrated by the present invention are achieved by the following specific technical means:

[0008] A smart car control experimental device that can be displayed intuitively, comprising a runway; a concave guide card edge is fixedly installed at the front edge and the rear edge of the runway respectively; L-shaped guard bars with uniform left and right intervals are vertically slidably inserted in the front side wall and the rear side wall of the runway, and the right-angle corner of the lower end of the guard bar is slidably connected to the upper end of the guide card edge; the guard bar comprises an annular groove, annular annular grooves are evenly opened on the guard bar at vertical intervals, and a connecting ring is sleeved in the annular groove; the guard bars are connected in series through connecting rings with uniform upper and lower intervals; a single-chip microcomputer is horizontally built-in in the middle of the bottom plane of the runway, and a track display mechanism with uniform intervals is embedded in the top plane of the runway, and the track display mechanism is connected to the single-chip microcomputer through ordinary electrical properties.

[0009] Furthermore, the runway includes an embedded groove, an anti-slip glass plate and a bottom groove. Two rectangular embedded grooves are symmetrically opened on the top plane of the runway. The upper ends of the embedded grooves are covered with transparent anti-slip glass plates. The upper end plane of the anti-slip glass plate is flush with the upper end plane of the runway. A rectangular bottom groove is opened in the bottom plane of the runway, and the inner end of the guardrail is slidably inserted in the front end side wall and the rear end side wall of the bottom groove.

[0010] Furthermore, the guide clamp edge comprises a guide groove, and a rectangular guide groove is longitudinally provided at a position corresponding to the guard rod in the top plane of the guide clamp edge.

[0011] Furthermore, the guardrail also includes a guide rod, a guide block, a pole light, a spring and a disconnect switch. A horizontal guide rod is vertically fixed to the lower end of the guardrail, and the guide rod is slidably inserted in the side wall of the runway, and the inner end of the guide rod is slidably inserted in the bottom groove. A baffle is fixedly installed at the innermost end of the guide rod, and the inner end of the baffle is tangent to the outer wall of the single-chip computer, and a spring is mounted on the guide rod outside the baffle.

[0012] Furthermore, the guard rod also includes a guide rod, a guide block, a pole lamp, a spring and a disconnect switch. A rectangular guide block is fixedly installed at the lower end of the guard rod, and the guide block is slidably embedded in the guide groove. A disconnect switch is installed in the inner side wall of the guide block. When the baffle at the inner end of the guide rod is tangent to the single-chip microcomputer, the inner side wall of the guide block is also tangent to the inner side wall of the guide groove. A pole lamp is fixedly installed at the upper end of the guard rod.

[0013] Furthermore, the connecting ring includes an elastic band, the connecting ring body is made of high-strength polymerized ethylene, and the connecting rings are fixedly connected by the elastic band.

[0014] Furthermore, the track display mechanism includes a track ring light and a photoelectric sensor.

Experiments can be repeatedly carried out based on this path.

[0018] Since the guide rod is slidably inserted in the side wall of the runway, and the inner end of the guide rod is slidably inserted in the bottom groove, a baffle is fixedly installed at the innermost end of the guide rod, and the inner end of the baffle is tangent to the outer wall of the single-chip computer, and a spring is mounted on the guide rod outside the baffle. When the guardrail is hit by the smart car, the guardrail can move outward to provide buffering capacity to prevent the smart car from rushing out of the runway or being damaged, and the guide block is slidably embedded in the guide groove, and a disconnect switch is installed in the inner end side wall of the guide block. When the baffle at the inner end of the guide rod is tangent to the single-chip computer, the inner end side wall of the guide block is also tangent to the inner end side wall of the guide groove. A pole lamp is fixedly installed on the upper end of the guardrail. By moving the guide block in the guide groove, the guardrail can be corrected to prevent the guardrail from tilting.
