Embodiment 2

[0066] Embodiment 2 This embodiment provides another implementation of an intelligent omnidirectional AGV trolley, the technical solution of which is the same as that of Embodiment 1, and the specific settings also include:

[0067] The main control unit 8 is composed of a UNO module and a mega2560 controller, wherein the UNO module is connected to the navigation sensor unit 7, the UNO module receives the signal sent by the 16-bit navigation sensor unit 7, and the 16-bit magnetic navigation sensor used in the navigation of the AGV The unit can accurately detect the position of the magnetic strip, so that the AGV will not deviate from the track during operation.

[0068] In addition, in order to reduce the CPU computing resources of the mega2560 main control board and improve the overall performance of the system, an Arduino UNO control board is added for auxiliary calculation, which is used to collect 16-bit magnetic navigation sensor signals.

[0069] The control program is e...

Embodiment 3

[0073] Embodiment 3 This embodiment provides a third implementation of an intelligent AGV omnidirectional trolley, and its technical solution is as in Embodiment 2. During the specific implementation process, it also includes:

[0074] The driving device adopts a spring anti-vibration device, the motor unit 4 and the omnidirectional wheel unit 1 are fixed, the spring is sleeved on the cylinder, and the wheel train is sleeved on the cylinder for connection;

[0075] as follows Figure 8 As shown, the spring anti-vibration device is to put the spring on the cylinder on the shell of the AGV. Figure 4 The parts are installed in the motor and then inserted into the cylinder. The top of the cylinder is threaded and connected with nuts. The spring supports the parts. If vibration occurs, the universal wheel will slide on the cylinder. This assembly is helpful shockproof.

[0076] The above methods help to protect the carried items from being dumped during operation, reduce the vib...

Embodiment 4

[0081] Embodiment 4 This embodiment provides an intelligent omnidirectional AGV car control method, including

[0082] The first step is to send a signal to the AGV car through the remote control, and the main control unit 8 of the AGV car decodes the sent information and runs the corresponding command;

[0083] If the stop signal is sent, the AGV car will stop;

[0084] If the signal sent is to run to the specified position, the AGV car will start the running self-check;

[0085] In the second step, the AGV trolley receives the control instruction that the trolley runs to the specified position, and the main control unit 8 judges the forward direction in the following manner:

[0086] According to the intersecting control algorithm, the magnetic navigation sensor of the navigation sensor unit 7 at the front lower middle part of the compartment 9 detects the number a, and the magnetic navigation sensor of the navigation sensor unit 7 at the rear lower middle part of the compa...

Abstract

The invention provides an intelligent omnidirectional AGV car and a control method thereof. The AGV car comprises a drive device, ultrasonic sensor units (2), a motion indicating lamp unit (5), a navigation sensor unit (7), a master control unit (8) and a carriage (9); The carriage (9) is a cabinet of a certain height; a chassis of the carriage (9) is a cube with four corners removed; the drive device comprises an omnidirectional wheel unit (1), a motor drive unit (3) and a motor unit (4); the drive device is installed on a chassis of the carriage (9); the master control unit (8) is installedinside the carriage (9); there are four ultrasonic sensor units (2). By designing the structure of the AGV car, the invention realizes the AGV car to rotate in a narrow space and even in place, and realizes the movement of the AGV car in the specified direction by giving different x, y, [theta].

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an intelligent omnidirectional AGV trolley and a control method thereof. Background technique [0002] In the era of rapid technological development, artificial intelligence system technology has become the focus of scientists around the world. As one of the products of artificial intelligence technology, AGV has been widely used in warehousing, manufacturing, dangerous place operations and special industries. [0003] For example, in some automotive fields, such as the wiring of Chevrolet, Toyota and other automobile factories, it has been widely used. After using the AGV trolley as the assembly line of the carrier, it not only reduces the assembly time, but also reduces the failure rate. [0004] AGV, which is equipped with electromagnetic or optical components, can walk along the planned path, has transportation functions and safety protection functions, ...
