Problems solved by technology

The disadvantage of this tracking scheme is that the photoelectric sensor of the trolley is extremely susceptible to interference from ambient light, and its operation stability and reliability are not high, so it is not suitable for operation in open air environments and places with strong light

Embodiment 1

[0032] working principle:

[0033] A control circuit module 7, a tracking circuit module 4, an induction probe L and other components are installed on the vehicle body 9, and two power motors 10 are respectively installed on the left and right sides of the vehicle body 9. By controlling the running speed and direction of the two motors , to control the running speed and running direction of the vehicle body 9 .

[0034] The invention adopts a metal detector as a tracking device, and uses a metal aluminum foil as the track belt 1, that is, a track line, and realizes the tracking function of the trolley by means of metal induction. The metal detector used is composed of a metal detector circuit 5 and an induction probe L. There is an electromagnetic oscillation circuit in the metal detector. The oscillating signal is radiated by an alternating magnetic field formed by the induction probe L. If there is a metal object nearby, the alternating magnetic field can Eddy currents are ...

Abstract

The invention discloses an inductive tracking trolley and a tracking method thereof. A plurality of metal detector circuits with the same function are arranged on a tracking circuit module, the output port of each circuit is connected with a control circuit module through a connecting wire, the input end of each circuit is connected with an inductive probe, and each metal detector circuit is provided with a potentiometer RP capable of adjusting the detection sensitivity; and when the inductive probe closes to a metal object, the level of the output port of the metal detector circuit is changed, the level signal is input to the control circuit module, and the control circuit module outputs control instructions to the trolley body. An aluminum foil rubber belt replaces the black rubber belt and is used as a trolley locus line, so that the running stability and reliability of the tracking trolley are improved, and the action space of the tracking trolley is broadened. Meanwhile, the aluminum foil rubber belt can be stuck on the back of pictorial paper or spray painting cloth drawn with different patterns to form an invisible locus line. The inductive tracking trolley can be applied to demonstration of various dynamic house models, commercial models and military models.

Description

technical field [0001] The invention relates to an electronic automatic control device and a control method thereof, in particular to an inductive tracking trolley and a tracking method thereof. Background technique [0002] The tracking car is widely used in the scientific practice activities of young people. The activity requires the tracking car to follow a trajectory line to the end. The trajectory line is usually formed by sticking black tape on the white ground. Among them, the Chinese patent, patent announcement number: CN6484303, announcement date: 2005.03.09; Chinese patent, patent announcement number: CN101976075A, announcement date: 2011.02.16 The inventions disclosed are all using photoelectric sensors as tracking devices, using black track lines The intensity of the light reflected from the white ground is used to detect the position of the tracking line, so that the trolley runs along the track line. The disadvantage of this tracking scheme is that the photoel...
