Description

Technical Field

[0001] The present invention relates to the technical field of parking space planning, and in particular to a scene monitoring and control system used in a multi-modal park. Background Art

[0002] With the acceleration of urbanization and the advancement of smart city construction, the park, as an important part of the city, has a direct impact on the quality of urban operation due to its management efficiency and intelligence level. In the daily operation of the park, vehicle parking management is an important link. Traditional park vehicle parking management relies on manual operation, which has problems such as low efficiency, untimely information update, and low parking space utilization. In addition, due to the lack of effective monitoring and control systems, the park is prone to traffic congestion and parking difficulties during peak hours.

[0003] In the existing park scene monitoring and control system, the parking space occupancy status monitoring is usually not accurate and real-time enough, and it is difficult to meet the rapidly changing parking needs. At the same time, the park's vehicle counting and time recording equipment are often single-function and lack intelligent data analysis and processing capabilities. In addition, the park's vehicle parking strategy is often simple and crude, and is not flexibly adjusted according to the actual situation of vehicle inflow and parking spaces.

[0004] In response to these problems, a new type of multi-modal scene monitoring and control system for park use needs to be developed. The system should have the following features: real-time parking space occupancy status monitoring, accurate vehicle counting and time recording, and intelligent vehicle parking strategy. Through this system, the automation and efficiency of park vehicle parking management can be improved, manual intervention can be reduced, the allocation of parking space resources can be optimized, and the operation efficiency and user experience of the park can be improved.

[0005] Therefore, how to develop a system that can comprehensively monitor the park usage scenarios and intelligently control vehicle parking has become an urgent problem to be solved in the field of park management. This will not only greatly improve the management efficiency of the park, but also promote the development of park management towards intelligence and automation. Therefore, the development of such an efficient, intelligent, and automated multimodal park scene monitoring and control system has become an important direction of park management technology research.

[0046] The first park is the park that the vehicle enters for the first time;

[0047] The second park is a park adjacent to the first park;

[0048] When the vehicle enters the first park, the park allocation strategy is executed;

[0049] The park allocation strategy is that if the number of free parking spaces in the first park is zero, the vehicle is recommended to enter the second park;

[0050] If the number of idle parking spaces in the first park is non-zero, the vehicle parking strategy is executed.

[0051] Optionally, executing a vehicle parking strategy according to the acquired inflow volume and parking capacity threshold includes:

[0059] From the parking capacity threshold G, we can get that when a vehicle enters the park, the monitoring time period is It is a high inflow period, and the proportion of vacant parking spaces If the parking capacity threshold G is exceeded, the normal parking strategy is implemented;

[0060] The normal parking strategy comprises the following steps:

[0084] S9: Execute S1-S6 and recommend the user to park in a parking space that can be parked simultaneously.

[0085] The present invention has the following beneficial effects:

[0086] 1. The scene monitoring and control system used in the multimodal park realizes the management and real-time monitoring of parking space resources in the park by obtaining the number of partitions in the park and generating a park set. The establishment of this set enables the system to monitor the parking space status of each park, and monitor the occupancy status, location and number of parking spaces in real time through parking space detection sensors, which can promptly reflect the vacancy, occupation or reservation of parking spaces, provide parking information for drivers, effectively avoid the inefficient behavior of blindly searching for parking spaces, and improve parking efficiency. The parking capacity threshold G is set, which is defined by the ratio of vacant parking spaces to the total number of parking spaces in the park. The park maintains at least 10% of vacant parking spaces in any time period, providing a guarantee for responding to sudden vehicle influxes.

[0087] 2. The scene monitoring and control system used in the multimodal park realizes real-time monitoring of the occupancy status of parking spaces in each park through parking space detection sensors, and generates a dynamically updated parking space set. This real-time monitoring mechanism can ensure the accuracy and timeliness of parking space data, provide drivers with timely parking information, reduce the time of finding parking spaces, and improve parking efficiency. By setting the state set function, the occupancy status of each parking space can be distinguished, including "idle state", "occupied state" and "reserved state". This state identification enables the driver to identify the empty space for parking, avoiding parking delays caused by unclear status. The parking space status update mechanism is set to update the current status of the parking space every time interval. By setting a parking space set for each park, the number and status of parking spaces in different parks can be managed. This set setting enables the system to flexibly respond to the parking needs of different parks and optimize parking space resources.

[0088] 3. The scene monitoring and control system used in the multimodal park realizes continuous monitoring of the parking status of the park through the collaborative work of the time recording unit and the vehicle counter unit. The monitoring time period T is set, and the 24 hours of a day are reasonably divided into m monitoring time periods. The clear start and end time points of each monitoring time period can monitor the changes in parking behavior within each time period, including the inflow and outflow of vehicles. By generating a set of monitoring time periods T, the establishment of set T compares and analyzes the parking conditions of each time period, thereby improving the utilization efficiency of parking resources. Through time period division and monitoring, the system can identify the peak and trough periods of parking demand, so as to reasonably allocate resources during peak periods and optimize the allocation of resources during trough periods.

[0089] 4. The scene monitoring and control system used in the multimodal park provides quantitative data support for the vehicle flow in the park by calculating the inflow and outflow within the monitoring time period T. The calculation formula of the inflow ensures the accuracy of the number of vehicles entering the park, and the calculation of the outflow records the number of vehicles leaving the park. By calculating the net flow, the overall increase or decrease of vehicles in the monitoring time period can be evaluated. The positive and negative values ​​of the net flow reflect the cumulative trend of vehicles in the park, providing a basis for further vehicle parking strategies. By setting the high inflow threshold P and the low inflow threshold A, the peak and trough periods of vehicle flow can be identified. When the net flow exceeds the high inflow threshold P, the system marks the monitoring time period as a high inflow time period, otherwise it is marked as a low inflow time period. This identification mechanism helps the system to adjust the allocation of parking resources in time to cope with different parking needs. By monitoring and analyzing the inflow and outflow, the system can reasonably allocate parking space resources during the high inflow time period, reduce the waiting time of vehicles, and improve parking efficiency.

[0090] 5. The scene monitoring and control system used in the multimodal park guides the parking of vehicles by setting the target parks for parking vehicles, namely the first park and the second park. The park that the vehicle first enters is defined as the first park, and the adjacent park is defined as the second park. When the parking spaces in the first park are insufficient, the vehicle can be guided to the second park in time, avoiding ineffective circulation and congestion of vehicles in the park and improving the traffic smoothness of the park. This zoning strategy helps to optimize the utilization of parking resources and ensure that vehicles can quickly find suitable parking spaces. When executing the park allocation strategy, the number of free parking spaces in the first park is monitored in real time to determine whether the vehicle needs to be guided to the second park. If the number of free parking spaces in the first park is zero, the system will suggest that the vehicle enter the second park, which helps to reduce the time the driver spends looking for parking spaces. By reasonably allocating vehicles to the first park and the second park, the system can ensure that the parking spaces are fully utilized and avoid parking difficulties caused by insufficient parking spaces.

[0091] 6. The scene monitoring and control system used in the multimodal park can adapt to the parking needs in different monitoring time periods and realize vehicle parking management by setting a variety of vehicle parking strategies, including low inflow strategy, high inflow strategy, normal parking strategy and allocation park strategy. In the normal parking strategy, by setting the number of adjacent idle parking spaces v and counter L, the system can identify and recommend suitable parking spaces, reducing the time for vehicles to find parking spaces. By traversing from the parking space set and updating the counter L according to the parking space occupancy status, the number of parking spaces v that can be parked at the same time can be calculated, improving the efficiency of parking space allocation. In the high inflow strategy, based on the comparison result between the number of vehicles that have entered and the number of parking spaces v that can be parked at the same time, it is recommended that users park in suitable parking spaces, avoiding the inconvenience of vehicles waiting for a long time or looking for parking spaces. By marking the parking spaces that can be parked at the same time and the ordinary parking spaces, it helps to help drivers quickly identify the parking space status, reduce congestion caused by improper parking space selection, and improve the utilization rate of parking spaces. By obtaining the number of remaining idle parking spaces in the monitoring time period and calculating the proportion of idle parking spaces.

[0092] 7. The scene monitoring and control system used in the multimodal park determines and selects the most appropriate parking strategy by comparing the inflow within the monitoring time period with the parking capacity threshold. In the high inflow time period, the allocated park strategy is executed, which gives priority to the parking needs of vehicles that arrive first, ensuring that vehicles can enter the park in an orderly manner and find parking spaces, reducing the waiting time for vehicles in queues. When ordinary parking spaces are full, the remaining vehicles can be recommended to the second park for parking in a timely manner. This inter-park allocation mechanism avoids vehicle congestion and improves the traffic smoothness of the park. When executing the allocated park strategy, by considering the relationship between the number of remaining free parking spaces and the vehicles that have entered, the reasonable allocation of parking space resources is achieved and the parking order is optimized. For the low inflow time period, the low inflow strategy will be executed to improve the utilization rate of parking spaces by recommending users to park in parking spaces that can be parked at the same time.
