Description

technical field [0001] The invention relates to the technical field of control of a three-dimensional logistics system, in particular to a system and method for optimizing the path of access to goods in a three-dimensional logistics system. Background technique [0002] In the three-dimensional logistics system, the stacker is the key operating machinery and the core of the entire automated three-dimensional logistics system. Whether the stacker can operate normally directly affects whether the entire automated three-dimensional logistics system can work normally. Its reasonable speed control, precise positioning design and accurate fault diagnosis system are the key factors for the entire automated three-dimensional logistics system to achieve high efficiency and high accuracy. The key to high-speed, high-security operation. The main bottleneck to further improve the efficiency of the automated three-dimensional logistics system is also the stacker, so improving the effici...

Problems solved by technology

However, a single algorithm has some defects more or less

For example, the ant colony algorithm has a slow convergence speed due to the lack of initial information, and due to the positive feedback of pheromones, it is easy to fall into a local optimum; the genetic algorithm does not use the feedback information in the system, resulting in redundant iterations of inaction, As a result, the solution efficiency is reduced, and because of the need for a large number of cross calculations in the evolution process, it brings additional calculation overhead, resulting in increased scheduling time, and it is difficult to meet the real-time requirements of actual engineering.

Moreover, the control method of the conventional three-dimensional logistics system can only realize the outbound and inbound operation of a single cargo of the stacker, so that the operating efficiency is bound to be greatly reduced in the case of a large number of outbound and inbound goods.

[0004] Moreover, in the control system of the three-dimensional logistics system of the prior art, the control of most of the stackers is realized by PLC and frequency converters. When the vibration is large, it seriously affects the service life of the stacker, and the vibration is too large to affect the safety of its handling goods

Generally speaking, the control system of the three-dimensional logistics system in the prior art still has the disadvantages of low control precision, low work reliability, high failure rate, and low logistics efficiency.
