Problems solved by technology

AGV automatic charging usually means that the AGV moves to the charging position so that its brush plate contacts the brush block of the charging pile for charging. At present, there is a potential safety hazard of charging the charging pile or the AGV brush plate before charging, and the contact detection method between the AGV brush plate and the brush block of the charging pile single unreliable problem
In addition, most AGVs do not communicate with charging piles to shake hands, and AGVs can only actively stop charging. In this way, AGVs will directly use contactors to disconnect high-current charging circuits. Long-term use will reduce the life of contactors, and its safety is low

Embodiment Construction

[0027] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The invention proposes an AGV automatic charging management and control system, which includes a master control dispatching station, an AGV terminal and a charging pile. The master control dispatcher monitors the status of multiple AGVs and charging piles in real time. The AGV that needs to be charged will be assigned the nearest idle charging pile by the master control dispatcher and controls the AGV and charging piles to complete charging. The master control dispatcher will according to the system task status, The AGV power is used to manage AGV charging to ensure that the AGV completes tasks efficiently; before charging, the AGV brush board and the charging pile brush block are not charged, and the power consu...

Abstract

The invention relates to an AGV automatic charging management and control system and method relating to the technical field of AGV control systems. In the scheme of the invention, when an AGV is not charged, an AGV swiping board and a charging pile swiping block are de-energized; the power consumption is low; and the safety is high. The contact between the AGV swiping board and the charging pile swiping block adopts the double detection mode of position confirmation and voltage detection to ensure that the AGV swiping board is in contact with the swiping block at an output end of a charging pile before power-on at the output end of the charging pile, preventing the short circuit problem due to electrification under abnormal conditions. The system and the method are safer and more reliable.A main control dispatching station is used for charging control, and the status of multiple AGVs and charging piles can be monitored, so that the resource distribution is more reasonable and efficient; the state of the AGV charging process is controllable; and the function is good and the safety is high.

Description

technical field [0001] The invention relates to the technical field of AGV control systems, in particular to an AGV automatic charging control system and method. Background technique [0002] AGV is an unmanned automatic guided vehicle. In order to work for a long time, automatic charging is one of its important functions. AGV automatic charging usually means that the AGV moves to the charging position so that its brush plate contacts the brush block of the charging pile for charging. At present, there is a potential safety hazard of charging the charging pile or the AGV brush plate before charging, and the contact detection method between the AGV brush plate and the brush block of the charging pile Single unreliable problem. In addition, most AGVs do not communicate with charging piles to shake hands, and AGVs can only actively stop charging. In this way, AGVs will directly use contactors to disconnect high-current charging circuits. Long-term use will reduce the life of c...
