2025-05-27
In the context of increasingly severe urban parking difficulties, intelligent automated parking garages have emerged, with their efficient access technology and optimization algorithms becoming key to solving parking problems.
The access technology of intelligent automated parking garages relies on advanced mechanical transmission and control systems. When a vehicle enters the garage, the intelligent guidance system at the entrance first identifies and locates the vehicle. High-definition cameras quickly scan the vehicle's outline, accurately measuring its length, width, and height, while the license plate recognition device reads the license plate information. This data is quickly transmitted to the central control system. The central control system, based on the vehicle's dimensions, selects a suitable vacant parking space in the three-dimensional spatial model of the garage. For example, for a small car, the system will prioritize assigning it a smaller but easily accessible standard parking space; while for larger SUVs or business vehicles, a spacious and structurally stable designated parking space will be assigned.
Next, the handling robot or elevator begins to work. Handling robots typically use wheeled or track structures and have high-precision positioning and navigation capabilities. After receiving instructions from the central control system, it quickly moves to the bottom of the vehicle and uses a hydraulic or electric lifting device to smoothly lift the vehicle. During handling, the robot's sensors monitor the vehicle's posture and surrounding environment in real-time to ensure that the vehicle does not collide during movement. For vertical lifting automated parking garages, the elevator undertakes the main handling task. The elevator car design matches the vehicle size and is made of high-strength steel to ensure sufficient load-bearing capacity. Its transmission system consists of a high-performance motor, steel wire rope or chain, and a precise speed control device. The motor drives the steel wire rope or chain to smoothly lift and lower the car, and the speed control device ensures that the speed of the car is smooth during lifting and lowering, avoiding damage to the vehicle due to excessive acceleration or deceleration.
Optimization algorithms are the core brain of the efficient operation of intelligent automated parking garages. Among them, path planning algorithms are particularly important. In multi-space, multi-level automated parking garages, how to allow handling robots or elevators to store vehicles in designated parking spaces with the shortest path and fastest time and quickly retrieve them when retrieving vehicles is a problem that path planning algorithms need to solve. This algorithm comprehensively considers the layout structure of the garage, the current operating status of various equipment, and the parking location of vehicles, and uses mathematical methods such as graph theory and search algorithms to calculate the optimal access path. For example, during peak hours, vehicles frequently enter and exit the garage, and the optimization algorithm will dynamically adjust the access order, prioritizing vehicles with shorter parking times and located on floors closer to the entrance and exit to reduce waiting time for other vehicles and improve overall access efficiency.
In addition, intelligent automated parking garages also use task scheduling algorithms. When multiple access tasks are generated simultaneously, the task scheduling algorithm reasonably allocates the garage's handling equipment, lifting equipment, and other resources based on the urgency of each task, required resources, and estimated completion time, ensuring that all tasks proceed in an orderly manner and avoiding equipment conflicts and resource waste. For example, when a handling robot is performing a vehicle entry task, the task scheduling algorithm will arrange another idle robot or elevator to handle new tasks based on the status of other tasks, or allow the robot performing the task to pause the current task at an appropriate time and prioritize more urgent tasks, such as the exit of emergency vehicles. Through the close combination of efficient access technology and optimization algorithms, intelligent automated parking garages can achieve fast and safe access to vehicles in limited space, greatly improving the utilization rate of urban parking resources.
