Problems solved by technology

The traditional RGV positioning method still uses an addressing chip plus an encoder. The disadvantage of this method is that if there are foreign objects in the track, it is easy to be interfered, resulting in deviations in counting. In addition, when there are many docking stations, a lot of addressing devices need to be installed. chip, the workload of fixing and adjustment is relatively large, the installation and maintenance cost is high, and the program structure of the PLC control system on the vehicle is complicated

Abstract

The invention discloses an RGV automatic positioning mode by adopting a frequency converter laser, and belongs to the technical field of RGVs. The technical key point is that a guide rail and an RGV arranged on the guide rail are comprised, the RGV is connected with the ground through driving wheels, and encoders are arranged on the driving wheels; a PLC and a frequency converter are arranged in the RGV, laser distance measuring sensors are arranged in the middles of the two ends of the RGV, and laser reflecting plates matched with the laser distance measuring sensors are arranged at the endsof the two ends of the guide rail. According to the present invention, the two laser distance measuring sensors are arranged, the distance data detected by the two laser distance measuring sensors canbe mutually corrected through the PLC on the RGV, and the measurement errors caused by the moving obstacles are eliminated to a certain extent, so that the positioning precision of the RGV can be improved.

Description

technical field [0001] The invention relates to the field of RGV trolleys, and more specifically relates to an RGV trolley adopting a frequency converter laser automatic positioning method. Background technique [0002] RGV is also called rail shuttle trolley. RGV trolley can be used in various high-density storage warehouses. The trolley channel can be designed to be arbitrarily long, which can increase the storage capacity of the entire warehouse, and it does not need a forklift to drive into the roadway during operation, making it safer. higher. Taking advantage of the advantage that forklifts do not need to enter the roadway, combined with the fast running of the trolley in the roadway, the operating efficiency of the warehouse is effectively improved. The traditional RGV positioning method still uses an addressing chip plus an encoder. The disadvantage of this method is that if there are foreign objects in the track, it is easy to be interfered, resulting in deviations...
