A method for real-time monitoring and positioning of AGVs

Abstract

The invention relates to an AGV real-time monitoring and positioning method. The AGV real-time monitoring and positioning method includes the following steps that 1, database logging: it is necessary to place multiple landmark cards in advance in the working area of an AGV, the card numbers of the landmark cards and the coordinates of the landmark cards relative to a starting point are recorded in a database in advance, the vehicle body direction of the AGV when the AGV is in a corresponding landmark card is recorded, and it is also necessary to reserve the operation route of the AGV into the database in advance; 2, location information acquisition: the card number where AGV is located, the distance that AGV moves and the error type information of the AGV itself are acquired through the UDP protocol, the operation route of the AGV is acquired based on the current card number and the coordinates of next card number are obtained; 3, location calculation: the present coordinates of the AGV are calculated out based on the current card number, the next card number and the moving distance, and the dynamic display are completed in an monitoring interface in combination with an AGV error type. According to the AGV real-time monitoring and positioning method, the AGV has high positioning accuracy, small accumulated error, a simple mathematical model and a small calculation amount.

Description

technical field [0001] The invention relates to the technical field of a control method for an automatic handling robot, in particular to a method for real-time monitoring and positioning of an AGV. Background technique [0002] AGV is the abbreviation of automatic guided vehicle. Specifically, it is equipped with automatic guidance devices such as electromagnetic or optical, and can travel along the prescribed guiding path. It has safety protection and various transfer functions. Usually AGV and control computer (console), navigation equipment, charging equipment and peripheral accessories form an AGV system. The main purpose of the control computer is to monitor the AGV in real time and send dispatch commands. [0003] In order to display the position of the AGV in the monitoring interface in real time, the main method currently used by major manufacturers is that when the AGV reads a certain card, it only dynamically flashes on the position of the card. Before reading the...

[0003] In order to display the position of the AGV in the monitoring interface in real time, the main method currently used by major manufacturers is that when the AGV reads a certain card, it only dynamically flashes on the position of the card. Before reading the next card, the AGV The position in the monitoring interface will not change, so the operator cannot know the real-time position of the AGV, which will affect the operator's accurate implementation of the dispatching AGV command
