Embodiment Construction

[0051] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0052] 1. Magnetic stripe signal error tolerance and error correction processing method

[0053] Such as image 3 As shown, a magnetic stripe signal error-tolerant and error-correction processing method includes the following multiple steps.

[0054] (1) Step S1, effective signal setting: M magnetic navigation sensors are set at each navigation control point, and N magnetic navigation sensors are set as effective points N according to the width of the magnetic stripe and the spacing of the magnetic navigation sensors, and the remaining M-N magnetic navigation sensors are invalid points, where M and N are both positive integers, and M≥N.

[0055] In order to adapt to magnetic strip guide rails with different magnetic strip widths, for exam...

Abstract

The invention discloses a magnetic stripe signal fault tolerance and error correction processing method and system. The method includes S1. M magnetic navigation sensors are arranged on each navigation control point, and N of the M magnetic navigation sensors are set as effective points N and the residual M-N magnetic navigation sensors are set as ineffective points based on the magnetic stripe width and the spacing of the magnetic navigation sensors; S2. in M magnetic signals, traversal is carried out from the left to the right or the right to the left to find the effective points, and the information of the effective points and the ineffective points is extracted to form a group of magnetic navigation signals; S3. the magnetic navigation signals are subjected to binary processing, the effective points are set as 1 and the ineffective points are set as 0, or otherwise, a group of navigation binary data is output; S4. through the combination with navigation prompting, the operation mode of an AGV on the magnetic stripe is determined, the navigation binary data is processed based on the selected operation mode, at the same time, effective information can be removed, and clear and effective navigation control data can be obtained; and S5, the AGC executes the navigation control data to complete the navigation operation.

Description

technical field [0001] The invention relates to the field of AGV control, in particular to a magnetic stripe signal error-tolerant error-correction processing method and system. Background technique [0002] At present, AGV (Automatic Guided Vehicle) has become an important equipment in intelligent manufacturing, advanced logistics and digital factories, especially in improving production efficiency and production accuracy. [0003] Recently, with the planning of Industry 4.0 and Made in China 2025, intelligent manufacturing and intelligent logistics have penetrated deeply into every field, especially in industries such as home appliances and automobile assembly. The demand for AGV independent R&D and production is imminent, and the core technology of AGV is mastered It is even more critical. It is obvious that the core technology of AGV is in AGV navigation. Common AGV navigation includes photoelectricity, vision, magnetic stripe, laser, etc., and the common AGV product on...
