Embodiment

[0017] Example: in figure 1 An AGV navigation and positioning device based on ultra-wideband UWB includes a box body 1, a power interface 2, a main control board 3, a UWB antenna 4 and a WIFI antenna 5. It is characterized in that a UWB antenna 4 is provided on one side of the box body 1, and the UWB antenna 4 is connected to the main control board 3 through wires. The other side of the box body 1 is provided with a WIFI antenna 5, and the WIFI antenna 5 is connected to the main control board 3 through wires. The top of the box body is provided with a power interface 2, and the power interface 2 is connected to the main control board 3 through wires.

[0018] The main control board 3 includes a CPU module 6, a DDR memory module 7, a FLASH storage module 8, a power supply module 9, a UWB antenna module 10, a WIFI module 11 and the like.

[0019] The CPU module 6 sends the position request signal to the UWB antenna module 10 through the SPI bus, and the UWB antenna module 10 c...

Abstract

The invention relates to an AGV (Automated Guided Vehicle) navigational location device based on a UWB (Ultra Wide Band), and belongs to the technical field of AGV navigational location devices. The AGV navigational location device is used for transmitting data through sending and receiving an extremely narrow pulse with a nanosecond grade or below rather than needing to use a carrier wave in a conventional communication system, so as to have a bandwidth-wide band UWB with a GHz magnitude. Numerous complicated application environments exist in the implementation of an AGV project; the navigational location device based on the UWB, as using a wireless communication way, can be used for effectively solving a wiring difficult problem in construction, and is used for simplifying systematic complexity and shortening the engineering implementation period. Compared with a conventional communication technique, the AGV navigational location device has a great difference; an AGV is enabled to have, in guide navigation, the advantages of being simple and convenient in path planning, flexible and reliable in system and being capable of simultaneously providing high-precision location functionsin both static and dynamic location aspects and avoiding a complicated engineering construction problem.

Description

technical field [0001] The invention relates to an ultra-wideband UWB-based AGV navigation and positioning device. It belongs to the technical field of AGV navigation and positioning devices. Background technique [0002] Traditional AGV (Automated Guided Vehicle) navigation and positioning mostly use electromagnetic guidance, tape guidance, laser navigation, inertial navigation and hybrid guidance, but all have their own shortcomings and limitations. The disadvantage of electromagnetic guidance is that the path is difficult to change and expand, and maintenance is difficult. The magnetic tape guide is easily disturbed by metal substances around the loop, the magnetic tape is easily damaged by mechanical damage, and the reliability of the guidance is greatly affected by the outside world. The disadvantages of laser guidance are high manufacturing cost, complex technology, relatively harsh environmental requirements, and not suitable for outdoor use. The disadvantage of in...
