Unmanned vehicle intelligent driving system based on park environment

Abstract

The invention discloses an unmanned vehicle intelligent driving system based on a park environment, and mainly solves the problems that the current park inspection manpower cost is too high, and part of inspection is dangerous. The system is composed of a sensor data processing module, a central control module, a motion control module, a visual processing module and a remote control module. The outputs of the sensor data processing module, the visual processing module and the remote control module are connected with the central control module; the sensor data processing module is used for acquiring inspection sensor data; the visual processing module detects traffic lights and S-bend roads appearing in the inspection process; the remote control module remotely issues a motion instruction; the central control module calculates the linear velocity and the angular velocity of the unmanned vehicle according to information transmitted by the three modules and sends the linear velocity and the angular velocity to the motion control module; and the motion control module converts the signal into a bottom layer motor control signal to drive the unmanned vehicle to run. According to the invention, manpower cost and danger are reduced, autonomous obstacle avoidance driving can be realized according to traffic rules, and the system can be used for unmanned vehicles in park environments.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an unmanned intelligent system, which can be used for unmanned vehicles in park environments. Background technique [0002] With the steady growth of my country's social economy, more and more giant enterprise factories, high-tech parks, and giant shopping malls continue to appear in national life. These places have put forward new special requirements for security work. Under normal circumstances, the security tasks in these places are completed by industrial security personnel. However, with the continuous expansion of inspection scope, mixed indoor and outdoor environments, and the continuous increase in labor costs, relying solely on industrial security personnel can no longer meet the increasing demands. Complex security needs. In addition, in some dangerous inspection environments, industrial safety personnel are not suitable for performing inspection...

AI Technical Summary

Problems solved by technology

However, most of these unmanned vehicles can only be used in closed environments such as factories in the park. They can only achieve simple obstacle avoidance autonomous driving during work, and cannot recognize traffic signs.

However, there are many traffic lights and lane lines outside the actual park, which not only require unmanned vehicles to autonomously avoid obstacles, but also require unmanned vehicles to follow traffic rules when driving. However, the existing unmanned vehicles Technology cannot achieve this goal. Unmanned vehicles cannot be used in the outdoor environment of the park. There are still problems such as high inspection costs when manual inspections are used for the above-mentioned park inspections, and some inspections are very dangerous.
