Storage logistic robot group control system based on visual guidance and RFID navigation

Abstract

The invention discloses a storage logistic robot group control system based on visual guidance and RFID navigation. The system comprises two CPU modules, a WIFI communication module, a motor control part, a camera module, an RFID module, an electric push rod module, a gyroscope module, an obstacle avoiding module, a power source module and an RFID chip. Multiple automatic guided vehicles (AGV) in a warehouse can be scheduled simultaneously to realize orderly operation, mutual interference among the AGV is avoided, and tasks can be orderly accomplished. Compared with a magnetic navigation system, the system is advantaged in that AGV driving paths can be more flexible.

Problems solved by technology

[0002] In recent years, with the rise of e-commerce, the increase in e-commerce orders has also increased the logistics demand. At this time, the traditional distribution operation mode has been unable to meet the needs of complex consumer orders.

Magnetic navigation and laser navigation are traditional navigation methods. Although magnetic navigation is cheap and stable, it can only run along a fixed track path and is only suitable for production and storage environments with relatively simple layouts; laser navigation has high navigation accuracy. , can dynamically plan paths, etc., but the price is high, and its positioning lever is easily blocked by the shelf, so it is more suitable for forklift transformation schemes, etc.

Inertial navigation technology is to install a gyroscope and an acceleration sensor on the AGV, and calculate the relative position of the car by integrating the data of the gyroscope and the acceleration sensor. The advantage of this technology is that it can realize its navigation without any auxiliary equipment. The disadvantage is that the navigation The accuracy is not high, the error will accumulate, and certain methods need to be taken to eliminate the error

Most of the existing navigation systems use two-dimensional code navigation, but once the two-dimensional code is defaced or covered, it cannot be recognized. This navigation system has high requirements for the laying of the site.
