AI Technical Summary

Problems solved by technology

[0003] First, the traditional three-dimensional garage only uses sensors and photoelectric elements to automatically and randomly access the parking spaces, and the access sequence and parking space management have not yet reached scientific, intelligent, and rationalization;

[0004] Second, although the genetic algorithm has a fast global search capability, it does not use the feedback information in the system, which often leads to redundant iterations of inaction and low solution efficiency;

[0005] The third is that the ant colony algorithm converges to the optimal path through the accumulation and update of pheromones, and has the ability of distribution, parallelism, and global convergence, but the lack of pheromones in the initial stage leads to slow algorithm speed;

[0006] Fourth, the action of the three-dimensional garage is complex, and the control system is required to realize sequential action control, speed control, positioning control and safety interlock control. Due to the advantages of the programmable logic controller (PLC), it can adapt to and meet the high-performance requirements of the three-dimensional garage. Therefore, PLC is used as the core of the three-dimensional garage control system in almost all automatic parking systems at present. However, due to the limitation of the I / O points and operation speed of the PLC control system, the PLC has a running speed when it is applied to the parking space scheduling of the three-dimensional garage. Problems with production costs and other aspects affect the overall efficiency and utilization of the garage, resulting in waste of vehicle access time and energy consumption.
