SHEN Zheng, LIANG Jianru, YANG Minglai, et al. Design of heavy load AGV control system based on S7-200 SMART PLC[J]. 2021, (8): 100-103. DOI: 10.13873/J.1000-9787(2021)08-0100-04.
In order to improve the load capacity of automatic guided vehicle(AGV)
realize automatic transportation of heavy goods
an AGV using PLC as core is designed. The motor uses geared motor to increase the load capacity of the AGV.Obstacle avoidance sensor are installed on front and back of AGV respectively
and range of obstacle avoidance can be set
safety of system is enhanced.The AGV car has two modes of operation
an automatic tracking mode and a wireless remote control mode
which can be applied to more places. The AGV automatic tracking function is realized by a magnetic navigation sensor and a PID algorithm
which uses a wireless remote control mode to control AGV motion.The experimental research shows that the AGV can start and stop smoothly when transporting goods of 10~20 t
and the AGV can recognize obstacles and stop in time in the obstacle avoidance range.
