Problems solved by technology

However, the calculation of these position and attitude deviations is only for the straight-line path model, and does not consider the arc-shaped path model that is widely used in practice.
Moreover, the turning magnetic signs of single-branch and multi-branch intersections in practice have not been considered.

Embodiment Construction

[0036] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0037] refer to figure 1 , the annular array magnetic guidance device of the present invention uses a plurality of magnetic detection elements to form three magnetic detection areas: an annular array, a linear array, and a linear extension end point. Among them, the first magnetic detection elements C1~Cn are installed on the bottom surface 2 of the magnetic guidance device. In this embodiment, n=16, and they are evenly distributed along the 3 directions of the circumference with a diameter D. The detection area center C of each magnetic detection element is The connecting line with the center O is in the radial direction 4 of the circle, and the included angle θ between adjacent connecting lines is equal. The second magnetic detection elements L1~Lm are installed on the bottom surface 2 of the magnetic guidance device. In this embodiment, m=6, arrange...

Abstract

The invention discloses a ring array magnetic guidance device and a method for identifying a guidance magnetic label thereof, belonging to the field of automatic delivery equipment. In the invention, a ring array formed by a plurality of first magnetic detection elements and a linear array formed by a plurality of second magnetic detection elements are distributed inside a shell to jointly form apath magnetic label detection part; two third magnetic detection elements arranged outside the shell form a coded magnetic label detection part; a temperature detection element and an environment magnetic field detection part formed by a plurality of fourth magnetic detection elements are distributed on the shell; and the path magnetic label detection part, the coded magnetic label detection part, the environment magnetic field detection part and the temperature detection element are respectively connected with a signal processing circuit. The invention provides the magnetic guidance device with the advantages of large information capacity, high identification precision, low calculation load and good reliability and the method for carrying out coded information identification, position attitude deviation calculation and road junction reversing information identification by utilizing the device.

Description

[0001] technical field [0002] The invention relates to a magnetic guidance device that can be used for guidance detection of intelligent vehicles and automatic guided vehicles and a guidance magnetic label identification method thereof, belonging to the field of automatic transportation equipment. Background technique [0003] Research on automatic guided technology began in the United States in the 1950s. In 1954, Barret Electronics developed the first automatic guided vehicle for cargo delivery, and then the application of automatic guided vehicles was extended to industrial production. In 1974 The Volvo Kalmar car assembly plant in Sweden uses automatic guided vehicles as a carrier for the automatic assembly line. Since the 1980s, the U.S. Department of Defense has started research on ground unmanned combat platforms, mainly targeting intelligent vehicles that adapt to different terrains and autonomously navigate. [0004] Automatic guidance technology has always bee...
