Abstract

The invention provides a four-wheel drive low-speed all-weather unmanned patrol car system. The four-wheel drive low-speed all-weather unmanned patrol car system comprises a patrol car body and a control system, wherein the patrol car body is provided with front and rear two pairs of driving wheels; a pair of driving wheels are driven by four direct-current motors; each direct-current motor is connected with a planetary speed reducer; each of a first front environment detection and protection system and a first rear environment detection and protection system in the control system is mainly composed of single-wire laser radars and a CCD camera; each of a second front environment detection and protection system and a second rear environment detection and protection system is mainly composedof two microwave radars; each of a front blind area detection and obstacle avoidance system and a rear blind area detection and obstacle avoidance system is composed of three ultrasonic transducers;the single-wire laser radars, the microwave radars, the CCD cameras, a wireless communication module and an auxiliary controller are connected with a main controller; the ultrasonic transducers and amotor driver are connected with the auxiliary controller; and the motor driver is connected with four direct-current motors. The system is high in stability, reliability and cost performance, rapid inoperating and processing speed and high in flexibility, and can effectively cope with bad weather.

Description

technical field

[0001] The invention belongs to the technical field of unmanned driving, and in particular relates to a four-wheel drive low-speed all-weather unmanned patrol car system. Background technique

[0002] With the acceleration of modernization, the number and scale of supermarkets, large docks, international airports, various exhibition centers, large logistics warehouses, high-end hotels, hospitals and other places are increasing, and various large living quarters and activity places are increasing day by day. Human activities and logistics and transportation have become more complex, requiring a lot of manpower, material resources and security resources to ensure the safe operation of this system. The current security technology is mainly based on human patrol and CCD camera positioning monitoring. These two methods can no longer meet the security needs of the existing large-scale and complex environments. The security patrol automation system that uses securit...
