Problems solved by technology
[0003] However, the navigation accuracy of the existing magnetic stripe navigation forklift system is low. In order to avoid the distance that the magnetic stripe navigation forklift deviates from the magnetic stripe during the backward operation of picking up and placing goods, the position and angle of the magnetic stripe navigation forklift are relatively accurate. , so that the goods can be picked and placed safely and accurately, and the operating speed of the magnetic strip navigation forklift is generally low
Therefore, the existing magnetic strip navigation forklift has the problems of low navigation accuracy and low operating speed

Embodiment Construction
[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0050] As mentioned in the background, the existing magnetic strip navigation forklift has the problems of low navigation accuracy and low running speed. The inventor found that the reason for this problem is that the existing technology uses a magnetic strip for straight-line path navigation. However, the body of a magnetic strip navigation forklift is generally long, and a magnetic strip cannot accurately identify the deviation of the vehicle body. For example, When the front end of the vehicle body runs on the ...

The invention discloses a magnetic stripe navigation fork system and a control method thereof. The magnetic stripe navigation fork system comprises a vehicle body, a wireless recognition device and apath identifier, wherein the wireless recognition device comprises a first magnetic stripe sensor and a second magnetic stripe sensor which are arranged out of the vehicle body, and the distances fromthe first magnetic stripe sensor and the second magnetic stripe sensor to one side edge of the vehicle body are not equal; the path identifier comprises a first magnetic stripe and a second magneticstripe, and the distance between the first magnetic stripe and the second magnetic stripe is matched with the first magnetic stripe sensor and the second magnetic stripe sensor; and the controller controls the vehicle body to operate along the first magnetic stripe and the second magnetic stripe according to first detection information and second detection information. The navigation precision ofthe magnetic stripe navigation fork is improved. The angle deviation of the magnetic stripe navigation fork system is reduced when cargoes are taken and placed as the vehicle body retreats to operateto take and place the cargoes, and the distance needed to adjust the angle and the position when the vehicle body retreats to operate is shortened, so that the operating speed and the operating efficiency of the magnetic stripe navigation fork are improved favorably.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of unmanned transport vehicles, and in particular to a magnetic strip navigation forklift system and a control method thereof. Background technique [0002] The magnetic strip navigation forklift is an unmanned guided vehicle (Automated Guided Vehicle, AGV), which is equipped with a magnetic strip automatic guidance device, and can run along the prescribed magnetic strip guidance path without the driver's control. Compared with other equipment commonly used in material transportation, the activity area of the magnetic strip navigation forklift does not need to lay track, support frame and other fixed devices, and is not limited by the site, road and space. Therefore, it has been widely used in automated logistics systems. [0003] However, the navigation accuracy of the existing magnetic stripe navigation forklift system is low. In order to avoid the distance that the magnetic stripe...
