Control circuit of intelligent vehicle with multiple sensors

Abstract

The invention discloses a control circuit of an intelligent vehicle with multiple sensors, and belongs to the technical field of control circuits of intelligent vehicles. The control circuit comprisesfour groups of single-chip microcomputers U1, U2, U3 and U4, a buzzer alarm circuit, a dial switch circuit, a camera circuit, a display screen circuit, an ultrasonic sensor circuit, a steering enginecircuit, a motor driving circuit, two groups of voltage reduction and rectification circuits, a pull-up resistor circuit, an encoder circuit and more than two groups of inductance amplification circuits. The control circuit of the invention has the beneficial effects that: an inductance value is utilized to perform secondary detection on a road, so that automatic tracking can be still effectivelyperformed at a track-free place, and a distance from an obstacle is detected by ultrasonic waves, and in cooperation with a camera, a good obstacle avoidance effect is achieved.

Description

technical field [0001] The invention relates to a control circuit for a smart car, in particular to a control circuit for a smart car with various sensors, and belongs to the technical field of control circuits for a smart car. Background technique [0002] The so-called smart car is based on the addition of advanced sensors (such as radar, camera, infrared, etc.), control systems, actuators and other devices on the basis of ordinary vehicles. Such intelligent information exchange enables the vehicle to have intelligent environmental awareness, can automatically analyze the safety and dangerous state of the vehicle, and enables the vehicle to reach the destination according to the wishes of the person, and finally achieve the purpose of replacing manual driving. It is a typical high-tech complex integrating computer, sensor technology, communication, artificial intelligence and automatic control technologies.

AI Technical Summary

Problems solved by technology

[0003] There are certain problems in the current smart cars. Traditional smart tracking cars use infrared tubes or laser tubes as image acquisition devices. The vision of the smart car is limited, thereby limiting the speed of the car. Although the laser tube has a relatively long collection distance, it is easy to be damaged, which increases the production requirements of the hardware, and the adaptability is not strong. Another point is that the addressing of the existing smart car is generally Use the camera to collect pictures of the track on the bottom surface and compare them to obtain corresponding processing. This method needs to be compared through pictures, the processing effect is low, and it is impossible to address the place without the track. The other is through the ground Set up multiple signs on the ground, and identify the road strength by identifying the signs on the ground. This method needs to set up signs on the ground, and after the identification, it also undergoes a lot of processing, and it cannot be addressed in places without a track, and the processing efficiency is low. , and the cost is high, so a camera-based multi-sensor smart car control circuit is designed to optimize the above problems
