Problems solved by technology

At present, China's automated terminals are still in their infancy. There are only a few terminals in the country. By laying a large number of magnetic nails on the designated ground, AGV realizes the automatic transportation of containers. It uses the AGV integrated navigation system based on magnetic nail technology. Tens of thousands of magnetic nails are buried underground, and the installation method of magnetic nails is cumbersome; the density of magnetic nails is high, and the price is high; resulting in a long construction period and huge investment costs; and it cannot meet the construction goals of ports that have been put into operation

Abstract

The invention relates to an accurate positioning device and method for assisting automatic driving. The device comprises road sign millimeter wave emitters, millimeter wave array receiving antennas, an automatic driving control system and a container truck. The plurality of road sign millimeter wave emitters are deployed on a guide path center line of a specified road surface corresponding to thecoordinate codes of a precise map; each of the two ends of the container truck is provided with a column of millimeter wave array receiving antennas, each millimeter wave array receiving antenna is composed of a plurality of antenna units which are arranged in two rows in a staggered mode, the automatic driving control system is installed on the container truck, and the automatic driving control system comprises a millimeter wave signal processor and a vehicle control unit. The cost of AGV transportation equipment is reduced, the efficiency is improved, and automatic transportation of variousport containers is met.

Description

technical field [0001] The invention relates to the field of AGV automatic transportation, in particular to a precise positioning device and method for assisting automatic driving. Background technique [0002] AGV (Automated Guided Vehicle) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, and having safety protection. At present, China's automated terminals are still in their infancy. There are only a few terminals in the country. By laying a large number of magnetic nails on the designated ground, AGV realizes the automatic transportation of containers. It uses the AGV integrated navigation system based on magnetic nail technology. Tens of thousands of magnetic nails are buried underground, and the installation method of magnetic nails is cumbersome; the density of magnetic nails is high, and the price is high; resulting in a long construction period and huge inves...
