Description

technical field

[0001] The invention relates to detection and positioning technology, in particular to a mobile trolley positioning device and positioning method. Background technique

[0002] Mobile trolleys are often used in production equipment in metallurgy, mining, chemical, textile and other industries. The position detection and positioning of mobile trolleys is a very important task. Currently commonly used mobile car positioning methods include the following:

[0003] 1) Use limit switches. A limit switch is installed on the traveling track of the trolley, and when the trolley reaches the limit switch, the action of the limit switch is triggered to send an in-position signal. The limit switches used can be mechanical, photoelectric or inductive, etc. Patent No. 200520040588.X, the patent entitled "Cutter Cart Origin Positioning and Locking Device" discloses this technology. The main advantage of using this positioning technology is that the structure is simple an...
