Sixteen-channel special-shaped tracking module

   It is of great practical significance to develop an efficient and intelligent tracking and obstacle avoidance car. At present, many countries in the world are actively conducting research, design and development of smart cars, which have been used in many fields, especially in the military and detection fields. Our country's research, development and application of smart cars started slowly, but it has also achieved significant results. At present, research on smart cars in various countries is still in the development stage. With the development of electrical automation technology, automatic control technology, artificial intelligence and computer technology With the rapid development of smart cars, the development of smart cars will surely reach an unprecedented height. Research Background Research Significance 3 Exploring Unknown Fields Moving and transporting work in some places requires a large amount of labor, but the form of labor is single. People need to constantly repeat an action to move objects from one place to another. The intelligent tracking and obstacle avoidance car can greatly free up the workload of workers. The smart car will carry objects from one place to another according to predetermined orders.
  This project is to make a sixteen-channel special-shaped tracking module, compared with traditional straight-line tracking. Our one has a higher recognition priority. Sawolai
, which can better perform curve identification and detection,
will introduce to you the following circuit composition.
This is the power circuit. We control the conduction and end of the triode to turn on or off the tracking tube.
This is our tracking tube circuit. From the figure It can be seen from the figure that when there is a black line below the tracking tube so that the light from the light-emitting tube cannot be reflected, OUT outputs a high level.
This is a comparison circuit composed of a comparator circuit built with LM393 and a sliding rheostat. OUT will be compared with the reference voltage we set.
Here is the LED indicator circuit, when the light emitted by our transmitter tube cannot be accepted by the receiver tube (that is, when the black line is scanned). The diode will glow as an indication.
This circuit is a data output circuit, and the data is a parallel input and serial output mode output. 16-bit data is output through the cascade of 74HC165 (I won’t introduce too much here, if you are interested, you can check the data manual by yourself)
