Problems solved by technology

The advantages of single-row are simple design and low cost, but the disadvantages are obvious: first, the detection accuracy is very low, and it can only be detected when there are many offsets in the operation process of the equipment, and the information transmission lags behind; the second is that it can detect There are not many types of intersections, which limits the scope of application

Embodiment Construction

[0030] The present invention will be further described below.

[0031] The system of the present invention mainly includes three modules: a magnetic sensor array module, a magnetic sensor acquisition module, and a line inspection main board module.

[0032] Magnetic sensor array module, the magnetic sensor module is composed of 15 magnetic sensors arranged in 3 rows and 5 columns;

[0033] Different from the prior art, the magnetic sensor module of the present invention does not adopt the traditional single-row magnetic sensor array (such as figure 1 As shown, the circles represent the magnetic navigation sensing unit, and the dotted box represents the pendulum position), but the following figure 2 The array shown ( figure 2 The 15 small circles represent 15 magnetic navigation sensing units), and the array is arranged in 3 rows and 5 columns.

[0034] The distance between the second column and the third column, the fourth column and the third column is equal, which is L1...

Abstract

The invention discloses a magnetic navigation system suitable for an automatic guided vehicle (AGV) and a navigation method. The system comprises a sensor module, a magnetic sensor signal acquisition module and a line patrol main board module, wherein a sensor array of the magnetic sensor signal acquisition module is arranged in a three-row five-column form; the magnetic sensor signal acquisition module acquires a transistor transistor logic (TTL) level signal of each sensor and encodes the level signal into a specified 16-scale protocol form; the level signal is converted into a 232 level signal and is transmitted to the line patrol main board module for analysis, and the current line patrol state of the AGV is obtained, the AGV left and right wheel differential adjustment is performed according to the line patrol state, and the AGV line patrol state and the intersection detection result are reported to an upper computer. The system is high in navigation speed and small in swing amplitude, can well control the motion track of the AGV and can be applied to various types of intersections.

Description

technical field [0001] The technology relates to the field of magnetic navigation, in particular to a magnetic navigation system and a navigation method suitable for AGVs. Background technique [0002] At present, circulation equipment guided by magnetic strips is widely used in modern production lines with a high degree of automation, such as AGV (automatic guided vehicle), automatic trolley AGC, trackless mobile shelves, etc. As automatic guidance, line inspection and intersection detection are very important in AGV control. [0003] At present, there are various magnetic navigation methods in the industry, each with its own characteristics, including single-row analog and single-row digital. The advantages of single row are simple design and low cost, but the disadvantages are obvious: first, the detection accuracy is very low, and it can only be detected when there are many offsets in the operation process of the equipment, and the information transmission lags behind; ...
