Management system and management method for intelligent warehouse AGV (Automatic Guided Vehicle)

Abstract

The invention relates to a management system for an AGV (Automatic Guided Vehicle), in particular to a management system and a management method for an intelligent warehouse AGV (Automatic Guided Vehicle). The management system comprises a vehicle radio frequency card, a radio frequency sensing node and a vehicle management system, wherein the radio frequency sensing node scans the vehicle radio frequency card and is connected with the vehicle management system through a wireless network; the vehicle radio frequency card is installed on one end of the vehicle; the radio frequency sensing node is installed above a goods shelf path; the radio frequency sensing node scans the vehicle radio frequency card and is provided with a wireless module, and scanning data is transmitted to the vehicle management system through the wireless network by the wireless module; and the vehicle management system calculates the position of the vehicle to realize the real-time positioning of the vehicle, plan the path of the vehicle and control the movement and the stopping of the vehicle. By use of the management system and a management method for the intelligent warehouse AGV, the vehicle can be subjected to real-time positioning and control, optimal path planning is carried out according to requirements, and the whole system has the advantages of low cost, high efficiency and stability in positioning and navigation.

Description

technical field [0001] The invention relates to a management system of an AGV trolley, in particular to a management system and a management method of an AGV trolley in an intelligent warehouse. Background technique [0002] With the continuous and in-depth development of wireless technology and computer technology, and the increasing demand of many application systems for determining the real-time location information of targets, positioning systems have attracted more and more attention. Positioning systems can be divided into outdoor positioning systems and indoor positioning systems according to different positioning environments. In recent years, the most widely used positioning system is the Global Positioning System (Global Position System, GPS). However, due to the complex layout of the indoor environment and the interference of non-line-of-sight noise, traditional positioning methods are not suitable for indoor positioning. [0003] At present, commonly used indoo...

Problems solved by technology

Among them, the Bluetooth positioning technology is a wireless transmission technology with short distance and low power consumption. It is positioned by measuring the signal strength. However, for complex space environments, the Bluetooth positioning system is greatly disturbed by noise signals, making its stability slightly poor; Infrared positioning technology uses optical sensors to receive light signals for positioning, and the recognition accuracy is high, but it is easily interfered by fluorescent lamps or other light sources, and has limitations in positioning; ultrasonic positioning technology uses reflective ranging method, according to the transmitted wave and The time difference of the echo is used to calculate the distance to achieve positioning, but it will be affected by multipath effects and non-line-of-sight propagation. At the same time, a large number of underlying hardware facilities are required, making the cost of positioning too high
