Description

Technical Field

[0001] This invention relates to the field of park vehicle management technology, and more specifically, to an intelligent outbound rerouting guidance method and system based on regionalized management of park traffic flow. Background Technology

[0002] Currently, with the rapid development of industrial parks, the number of enterprises within the parks is constantly increasing, and the number of vehicles in the parks is also increasing significantly during the same period, leading to increasingly higher requirements for vehicle management within the parks.

[0003] In the daily operation of the park, the demand for vehicle passage and parking is usually constant, especially during peak office hours and commuting periods. In certain scenarios, vehicles in some areas are prone to congestion, which puts great pressure on the park's traffic order and vehicle management.

[0004] In the existing technology, the layout of parking spaces in parks is generally square-shaped. This layout has certain advantages, such as making the park layout more square and beautiful, and the greater distance between adjacent vehicles, which makes it easier for drivers and passengers to open the car door to get in and out of the car. Moreover, vehicles can also easily turn and drive out from the parking space to the left or right as needed, making the overall comprehensive functionality stronger.

[0005] However, in actual use, this square-shaped parking space layout still has significant drawbacks. When vehicles are parked on both sides of a space and try to exit, they typically need to travel a longer distance to complete the turning maneuver, directly resulting in low overall vehicle exit efficiency. This is especially pronounced during peak traffic hours, such as evening rush hour, when a large number of vehicles exit simultaneously, exacerbating the problem of low exit efficiency in congested areas. This not only easily causes traffic congestion but also increases the risk of collisions with adjacent vehicles or other obstacles during the long exit and turning maneuvers. This significantly increases the difficulty of managing traffic flow in congested areas within the park and fails to meet the park's requirements for efficient and safe vehicle management. Summary of the Invention

[0006] To address this issue, the present invention provides an intelligent outbound reversal guidance method and system based on regionalized traffic flow control within a park, thereby solving the problem of low efficiency in the management of regionalized parking spaces within a park in the existing technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A smart outbound rerouting guidance method based on regionalized traffic flow control in a park includes the following steps: Obtain information on peak traffic hours and congested parking spaces within the park; Based on the location of congested parking spaces, a regionalized parking space exit guidance and control system will be established. During peak traffic hours, the vehicle relocation control system assists in completing vehicle relocation control based on the parking space exit relocation guidance and control system; When it is not during peak traffic hours, continue to adjust the vehicles to their initial state based on the parking space exit and relocation guidance and control system.

[0008] Based on the above technical solution, the present invention is further described as follows: As a further aspect of the present invention, The acquisition of peak traffic hours and congested parking spaces within the park specifically includes: Traffic flow monitoring equipment is deployed at road intersections, parking lot entrances and exits, and parking areas within the park to collect real-time vehicle traffic and parking data for each area of ​​the park within a preset period. The collected vehicle traffic data and parking data are transmitted to the data processing center, where data cleaning algorithms are used to preprocess the data and remove abnormal and redundant data. Next, the preprocessed vehicle traffic data was analyzed to calculate the vehicle traffic density for each time period within a specific monitoring area. The formula for calculating vehicle traffic density is as follows: ρ=N / (L×W) (1) In the formula: ρ represents vehicle traffic density, in units of vehicles / square meter; N represents the number of vehicles passing through a specific monitoring area within a preset time period, in units of vehicles; L represents the road length of the specific monitoring area, in units of meters; W represents the road width of the specific monitoring area, in units of meters; A preset vehicle traffic density threshold is set, and the vehicle traffic density of each time period is compared with the preset density threshold. The time periods when the vehicle traffic density exceeds the preset density threshold are selected and determined as peak traffic periods. The preprocessed parking data is analyzed to calculate the vehicle dwell time and exit waiting time for each parking space. The vehicle dwell time is the difference between the time it takes for a vehicle to enter the parking space and the time it takes to leave the parking space; the exit waiting time is the difference between the time it takes for a vehicle to start its exit and the time it actually leaves the parking space. The system presets vehicle dwell time thresholds and exit waiting time thresholds. It compares the vehicle dwell time of each parking space with the preset dwell time threshold and the exit waiting time with the preset waiting time threshold. Parking spaces where both dwell time and exit waiting time exceed the corresponding preset time thresholds are identified as congested parking spaces.

[0009] As a further aspect of the present invention, The aforementioned system for guiding and controlling parking space exits based on congested parking spaces is regionalized and includes: For a given congested parking space, it is divided into several specific parking areas. Each specific parking area contains several groups of parking spaces. For each group of parking spaces in each specific parking area, a steel support platform is pre-configured, and the size of the steel support platform matches the size of its corresponding parking space. The support turntable is pre-embedded and positioned in the foundation ground corresponding to the center bottom of the steel bearing platform. The rotational kinetic energy output end of the support turntable is connected to the center bottom of the steel bearing platform for transmission assembly, so that the steel bearing platform can be rotated and adjusted based on the support turntable. A hydraulic cylinder mechanism is configured on one side corresponding to the specific parking area. The linear kinetic energy output end of the hydraulic cylinder mechanism is connected to a transmission cam shaft fixed to the bottom of the tail end of each group of steel bearings via a transmission link. The base of the hydraulic cylinder mechanism is assembled on a lead screw guide mechanism. The linear drive direction of the lead screw guide mechanism is set perpendicular to the linear drive direction of the hydraulic cylinder mechanism. Based on the self-driving action of the hydraulic cylinder mechanism and its corresponding adaptive displacement action of the lead screw guide mechanism, each group of steel bearing platforms is synchronously rotated and adjusted. A monitoring and audible / visual warning system is also installed at the rear of the specific parking area. The monitoring and audible / visual warning system is electrically connected to the data processing center and control module.

[0010] As a further aspect of the present invention, The aforementioned system, corresponding to peak traffic hours, assists in vehicle relocation control based on the parking space exit relocation guidance and management system. Specifically, it includes: Determine whether a specific parking area meets the conditions for turning around and driving. The specific conditions for turning around and driving include no human activity in the area and the minimum distance between adjacent vehicles being higher than the predetermined standard range. The monitoring and audio-visual warning mechanisms in the parking space exit and relocation guidance and control system are used to monitor the activity of people in specific parking areas and the minimum distance between adjacent vehicles in real time. The monitoring and audible / visual warning system utilizes high-definition cameras and infrared detectors to collect real-time images and infrared signals from specific parking areas. These signals are then transmitted to a data processing center for analysis to determine the presence of human activity within the area. Simultaneously, image recognition algorithms process the collected images to calculate the distance between adjacent vehicles. Specific distance calculation methods include: Select key feature points of vehicles, calculate the straight-line distance between adjacent vehicles using the coordinates of the key feature points, compare the distances between all adjacent vehicles, and filter out the minimum value, which is the minimum distance between adjacent vehicles in this specific parking area.

[0011] As a further aspect of the present invention, The aforementioned system, corresponding to peak traffic hours, assists in vehicle relocation control based on the parking space exit relocation guidance and management system. Specifically, it also includes: When the specific parking area is determined to meet the turning drive conditions, the control module sends a drive command to the hydraulic cylinder mechanism and the lead screw guide mechanism. The hydraulic cylinder mechanism's own driving action and its corresponding adaptive displacement action to the lead screw guide mechanism work together to drive each group of steel bearing platforms to synchronously rotate and turn based on the support turntable. During the adjustment process, the hydraulic cylinder mechanism performs linear extension and retraction movements according to the command, and transmits the driving force to the transmission cam of the steel bearing platform through the transmission linkage, causing the steel bearing platform to rotate around the support turntable; The lead screw guide mechanism performs adaptive linear drive according to the adjustment requirements, so as to drive the hydraulic cylinder mechanism to adaptively shift based on the orientation of the connection line of each set of transmission cams, and each set of steel bearings can be synchronously rotated and adjusted.

[0012] As a further aspect of the present invention, The method for setting the specific steering parameters of the rotation adjustment includes: The basic standard range for the minimum adjacent vehicle spacing is 1~1.2m, and the minimum adjacent vehicle spacing between vehicles in this specific parking area is monitored in real time by the monitoring and sound and light warning system. When the real-time monitored minimum adjacent vehicle spacing value reaches the upper limit of the basic standard range of 1.2m, it is determined that the current rotation angle of the steel bearing platform meets the standard angle state of the current single-turn control. The control module issues a stop command, the hydraulic cylinder mechanism and the lead screw guide mechanism stop working, and the turning operation is completed.

[0013] As a further aspect of the present invention, The aforementioned system, corresponding to peak traffic hours, assists in vehicle relocation control based on the parking space exit relocation guidance and management system. Specifically, it also includes: During peak traffic hours, the monitoring and audio-visual warning system will monitor the frequency of traffic in the opposite lane of the designated right-turn guide lane in this specific parking area in real time. The formula for calculating the frequency of traffic in the opposite lane is: f=M / T (2) In the formula: f represents the frequency of traffic in the opposite lane, in vehicles / second; M represents the number of vehicles passing through the opposite lane within the preset time interval, in vehicles; T represents the preset time interval, in seconds; A standard frequency threshold is preset for the frequency of oncoming traffic. When the frequency f of oncoming traffic monitored in real time exceeds the preset standard frequency threshold, the minimum adjacent vehicle distance value for steering the vehicle is adjusted to 1m. When the minimum adjacent vehicle distance value reaches 1m, the steering operation stops to reduce the steering range.

[0014] As a further aspect of the present invention, The aforementioned system, corresponding to peak traffic hours, assists in vehicle relocation control based on the parking space exit relocation guidance and management system. Specifically, it also includes: A safe frequency threshold for the oncoming lane driving frequency f is preset, and a hierarchical mechanism is introduced to set the minimum adjacent vehicle spacing standard for driving vehicles to turn based on the real-time monitored oncoming lane driving frequency f. The safe frequency threshold is set to 0.05 vehicles / second; When the real-time monitored oncoming lane traffic frequency f exceeds the preset standard frequency threshold of 0.1 vehicles / second, the minimum adjacent vehicle spacing value for driving the vehicle to turn is set to 1m. When the real-time monitoring of the oncoming lane traffic frequency f does not exceed the standard frequency threshold of 0.1 vehicles / second, but exceeds the safe frequency threshold of 0.05 vehicles / second, the minimum adjacent vehicle distance value for driving the vehicle to turn is set to 1.1m. When the real-time monitored oncoming lane traffic frequency f does not exceed the safe frequency threshold of 0.05 vehicles / second, the minimum adjacent vehicle spacing value for steering the vehicle is maintained at the upper limit of the basic standard range of 1.2m.

[0015] As a further aspect of the present invention, When traffic is not at its peak, the system will continue to guide and control vehicles back to their initial state based on the parking space exit and relocation guidance system. This includes: If the current time period is not within the identified peak traffic period, the off-peak working mode of the parking space exit relocation guidance and control system will be activated to relocate the steel platform and its corresponding vehicles to their initial state. The initial state is the original position of the steel bearing platform before it is rotated or oriented. At this time, the steel bearing platform and its corresponding vehicle are in a square position. The reset procedure of the parking space exit direction guidance and control system is initiated. The control module sends a reverse drive command to the hydraulic cylinder mechanism and the lead screw guide mechanism. The hydraulic cylinder mechanism's own driving action and its corresponding adaptive displacement action to the lead screw guide mechanism drive each group of steel bearing platforms to reverse rotate and adjust based on the support turntable. During the reset process, the monitoring and audible and visual warning mechanism continuously monitors the activity of people in the specific parking area and the distance between adjacent vehicles in real time. The control module adjusts the operating speed of the hydraulic cylinder mechanism and the lead screw guide mechanism according to the monitored distance between vehicles. The smaller the distance between adjacent vehicles, the slower the operating speed. Until the steel support platform returns to its initial set position, the support turntable, hydraulic cylinder mechanism, and lead screw guide mechanism all return to their initial state, completing the adjustment operation of turning the vehicle back to its initial state.

[0016] An outbound relocation guidance system based on the aforementioned intelligent outbound relocation guidance method for regionalized traffic flow control in a park, the system comprising: The traffic flow data acquisition module is used to acquire peak traffic hours and congested parking spaces within the park. The control system construction module is used to build a regionalized control system for guiding parking space exit based on congested parking spaces. The peak-hour reversal module is used to assist in the reversal control of vehicles during peak traffic hours, based on the parking space exit reversal guidance and control system. The off-peak reset module is used to continue to adjust vehicles to their initial state based on the parking space exit and relocation guidance and control system when there is no peak traffic period.

[0017] The present invention has the following beneficial effects: 1. This invention obtains information on peak traffic hours and congested parking spaces within the park, and constructs a regionalized parking space exit and relocation guidance and control system. It implements differentiated relocation control strategies during peak traffic hours and resets the parking spaces to their initial state during off-peak hours. This effectively solves the problems of low exit efficiency and poor coordination and control flexibility in traditional conventional parking space layouts, thereby achieving efficient and refined management of traffic flow in the park.

[0018] 2. Based on the collection of multi-dimensional traffic flow and parking data by traffic flow monitoring equipment, it is possible to accurately locate peak traffic periods and congested parking spaces, providing reliable data support for subsequent traffic direction guidance and control, avoiding the blindness of the control system configuration, and improving the accuracy and effectiveness of vehicle management in the park.

[0019] 3. Specific parking areas are divided for congested parking spaces, and a direction guidance and control system is configured to achieve synchronous and smooth turning of vehicles within specific parking areas. At the same time, the regionalized architecture design allows the control system to flexibly adapt to the needs of different congested parking spaces, improving overall applicability.

[0030] like Figure 1As shown, this invention provides an intelligent outbound reversal guidance method based on regionalized traffic flow management within a park. This method accurately acquires relevant traffic flow data within the park through regionalization and constructs a regionalized reversal guidance and management system. It then implements differentiated reversal management strategies for different traffic flow periods, effectively solving the shortcomings of traditional conventional parking space layouts such as low outbound efficiency, susceptibility to collisions and damage, and poor flexibility in coordinated control. This enables efficient and refined management of traffic flow within the park. Specifically, it includes the following steps: S1: Obtain information on peak traffic hours and congested parking spaces within the park; The specific process is as follows: Traffic flow monitoring equipment is deployed at road intersections, parking lot entrances and exits, and parking areas within the park. This equipment includes, but is not limited to, video surveillance cameras, infrared sensors, and inductive loop detectors. It is used to collect real-time vehicle traffic and parking data for each area of ​​the park within a preset period. The vehicle traffic data includes information such as vehicle passage time, speed, number of vehicles, and frequency of traffic in opposite lanes. The parking data includes information such as vehicle entry time, exit time, vehicle dwell time, and waiting time to exit the parking space. The preset period can be adjusted from 7 to 30 days according to the park's conditions to ensure that the collected data is representative and comprehensive and can reflect the normal characteristics of traffic flow in the park. The collected vehicle traffic data and parking data are transmitted to the data processing center. The data is preprocessed using data cleaning algorithms to remove abnormal and redundant data, thereby improving the accuracy and reliability of the data. Specifically, abnormal data includes erroneous data caused by equipment failure, data that exceeds reasonable limits, such as data that the vehicle speed is 0 for too long, or data that the vehicle stays for a longer period than the park's operating time. Redundant data is directly removed. Next, the preprocessed vehicle traffic data was analyzed to calculate the vehicle traffic density for each time period within a specific monitoring area. The formula for calculating vehicle traffic density is as follows: ρ=N / (L×W) (1) In the formula: ρ represents vehicle traffic density, in units of vehicles / square meter; N represents the number of vehicles passing through a specific monitoring area within a preset time period, in units of vehicles; L represents the road length of the specific monitoring area, in units of meters; W represents the road width of the specific monitoring area, in units of meters; A preset vehicle traffic density threshold is set based on the designed traffic capacity of the park's roads, historical traffic data, and the park's management requirements. For example, the preset vehicle traffic density threshold is 0.5 vehicles / square meter. The vehicle traffic density of each time period is compared with the preset density threshold, and the time periods when the vehicle traffic density exceeds the preset density threshold are selected and identified as peak traffic periods. The preprocessed parking data is analyzed to calculate the vehicle dwell time and exit waiting time for each parking space. The vehicle dwell time is the difference between the time it takes for a vehicle to enter the parking space and the time it takes to leave the parking space; the exit waiting time is the difference between the time it takes for a vehicle to start its exit and the time it actually leaves the parking space. Preset thresholds for vehicle dwell time and exit waiting time are implemented. These thresholds are set with reference to the park's average parking time, drivers' and passengers' travel habits, and the park's management requirements. For example, the vehicle dwell time threshold is set to 2 hours, and the exit waiting time threshold is set to 2 minutes. The vehicle dwell time and exit waiting time for each parking space are compared with the preset dwell time thresholds, and the exit waiting time is also compared with the preset waiting time thresholds. Parking spaces where both dwell time and exit waiting time exceed the corresponding preset thresholds are identified as congested parking spaces. In addition, factors such as parking space utilization and the occupancy of adjacent parking spaces can be used to further confirm congested parking spaces to ensure accurate identification. By implementing this step, we can accurately grasp the peak hours of traffic flow in the park and the distribution of congested parking spaces, providing a reliable data foundation for the subsequent construction of a targeted control system and the implementation of traffic diversion guidance. This avoids the blind configuration of the control system and improves the accuracy and effectiveness of vehicle management in the park. S2: Based on congested parking spaces, construct a regionalized parking space exit guidance and control system; The specific process is as follows: Please refer to Figure 2 For a given congested parking space, it is divided into several specific parking areas. Each specific parking area contains several groups of parking spaces. For each group of parking spaces in each specific parking area, a steel support platform 1 is pre-configured. The size of the steel support platform 1 matches the size of its corresponding parking space. The steel support platform 1 is made of high-strength steel to ensure that it has sufficient load-bearing capacity and structural stability. A support turntable 11 is pre-embedded and positioned in the foundation ground corresponding to the center bottom of the steel bearing platform 1. The support turntable 11 adopts a high-precision rotating mechanism, and the rotational kinetic energy output end of the support turntable 11 is connected to the center bottom of the steel bearing platform 1 for transmission assembly, so that the steel bearing platform 1 can be rotated and adjusted based on the support turntable 11. The transmission method between the support turntable 11 and the steel bearing platform 1 can be selected, but is not limited to, flange connection or key connection, to ensure the transmission accuracy and kinetic energy stability between the support turntable 11 and the steel bearing platform 1. As a preferred embodiment, the height of the steel support platform 1 from the ground can be set to 0.5~2cm, and universal support wheels with their bottom surfaces in contact with the ground are embedded in the bottom of the four corners of the steel support platform 1. The universal support wheels can effectively distribute the weight of the steel support platform 1, improve the stability and smoothness of the movement of the steel support platform 1 when it is rotated and adjusted, and prevent the steel support platform 1 from tilting, jamming or being damaged by violent friction with the ground during rotation. At the same time, it can also reduce the load on the support turntable 11 and extend the service life of the support turntable 11. Furthermore, a hydraulic cylinder mechanism 2 is configured on one side corresponding to the specific parking area. The hydraulic cylinder mechanism 2 is a high-pressure, high-thrust hydraulic cylinder. The linear kinetic energy output end of the hydraulic cylinder mechanism 2 is connected to a transmission cam 12 fixed to the bottom of the tail end of each steel bearing 1 via a transmission link 21. The transmission link 21 is made of high-strength alloy material so as to effectively transmit the driving force of the hydraulic cylinder mechanism 2 to the transmission cam 12 and further ensure that the transmission cam 12 can effectively drive the steel bearing 1 to move synchronously. Please refer to Figure 3 The base of the hydraulic cylinder mechanism 2 is assembled on the lead screw guide mechanism 3. The lead screw guide mechanism 3 adopts a ball screw guide, and the linear drive direction of the lead screw guide mechanism 3 is set perpendicular to the linear drive direction of the hydraulic cylinder mechanism 2. Based on the self-driving action of the hydraulic cylinder mechanism 2 and its adaptive displacement action corresponding to the lead screw guide mechanism 3, the synchronous rotation and orientation of each group of steel bearing platform 1 is achieved. Both the hydraulic cylinder mechanism 2 and the lead screw guide mechanism 3 are equipped with high-precision position sensors to monitor the movement position and stroke parameters of the corresponding mechanisms in real time, ensuring motion accuracy and control accuracy. A monitoring and audible / visual warning mechanism 4 is also installed at the rear of the specific parking area. This mechanism 4 is electrically connected to the data processing center and control module to transmit real-time monitoring information to the data processing center, receive instructions from the control module, promptly issue audible / visual warnings, and monitor the minimum distance between adjacent vehicles in the specific parking area. Specifically, the monitoring and audible / visual warning mechanism 4 includes, but is not limited to, a high-definition camera, an infrared detector, a sound alarm, and a flashing light alarm. The high-definition camera captures real-time images of the specific parking area to clearly identify whether there is human activity, the parking location of vehicles, and the real-time distance between adjacent vehicles. The infrared detector assists in monitoring human activity within the area, enabling accurate detection and identification even in low-light conditions. The sound alarm uses a high-decibel speaker to issue audible warnings, and the flashing light alarm uses high-brightness LEDs to issue visual warnings.

[0031] As another preferred embodiment, the top surface of the steel support 1 is provided with wheel alignment guide grooves. The number and size of the wheel alignment guide grooves are adapted to the number and size of the vehicle's wheels, and the groove depth is set to 3~5cm to help the wheels fit more easily into the wheel alignment guide grooves. This helps guide the vehicle to park accurately, making the distance between adjacent vehicles in this specific parking area more uniform, reducing the problem of uneven spacing caused by vehicle parking deviation, providing better basic conditions for subsequent rotation and adjustment operations, and further ensuring the safety and accuracy of the adjustment process.

[0032] In one optional implementation, the support turntable 11 can be replaced by an electric turntable instead of a hydraulic turntable. The electric turntable has the advantages of fast response speed and high control precision, and can meet the adjustment requirements in different scenarios. The parking space exit and relocation guidance and control system constructed through this step provides a stable architectural foundation for subsequent relocation guidance of vehicles in specific parking areas. At the same time, the regionalized construction makes the control system more flexible to adapt to the needs of different congested parking spaces, improving the applicability and scalability of the system.

[0033] S3: Corresponding to peak traffic periods, the vehicle relocation control is assisted by the parking space exit relocation guidance and control system. The specific process is as follows: To determine whether a specific parking area meets the conditions for turning around and driving, the specific conditions for turning around and driving include at least the absence of people in the area and the minimum distance between adjacent vehicles being higher than the predetermined standard range. The monitoring and sound and light warning mechanism 4 in the parking space exit and relocation guidance and control system 4 monitors the activity of people in specific parking areas and the minimum adjacent distance between vehicles in real time; The high-definition cameras and infrared detectors in monitoring and audible / visual warning system 4 work together to collect images and infrared signals of specific parking areas in real time, and transmit them to the data processing center for analysis to determine whether there is human activity in the area; at the same time, image recognition algorithms are used to process the collected images to calculate the distance between adjacent vehicles. Specific distance calculation methods include, but are not limited to: Select key feature points of the vehicle, such as the front and rear of the vehicle. Calculate the straight-line distance between adjacent vehicles using the coordinates of the key feature points. Compare the distances between all adjacent vehicles and select the minimum value, which is the minimum distance a between adjacent vehicles in this specific parking area. Please refer to Figure 4When the specific parking area is determined to meet the turning drive conditions, the control module sends a drive command to the hydraulic cylinder mechanism 2 and the lead screw guide mechanism 3. The hydraulic cylinder mechanism 2, through its own driving action and the corresponding adaptive displacement action of the lead screw guide mechanism 3, coordinates to drive each group of steel bearing platforms 1 to synchronously rotate and turn based on the support turntable 11. Specifically, during the turning process, the hydraulic cylinder mechanism 2 performs linear extension and retraction movement according to the command, and transmits the driving force to the transmission cam shaft 12 of the steel bearing platform 1 through the transmission link 21, causing the steel bearing platform 1 to rotate around the support turntable 11. At the same time, the lead screw guide mechanism 3 performs adaptive linear drive according to the turning requirements, so as to drive the hydraulic cylinder mechanism 2 to adaptively shift based on the orientation of the line connecting each group of transmission cam shafts 12, thereby ensuring that each group of steel bearing platforms 1 can synchronously and smoothly rotate and turn. The specific method for setting the steering parameters is as follows: the basic standard range of the minimum adjacent vehicle spacing is preset to 1~1.2m. The monitoring and audible and visual warning mechanism 4 monitors the minimum adjacent vehicle spacing between vehicles in this specific parking area in real time. Since the relative spacing between adjacent vehicles will gradually decrease as the vehicle turns, when the value of the minimum adjacent vehicle spacing monitored in real time reaches the upper limit of the basic standard range of 1.2m, it is determined that the rotation angle of the current steel support platform 1 meets the standard angle state of the current single steering control. The control module issues a stop command, the hydraulic cylinder mechanism 2 and the screw guide mechanism 3 stop working, and the steering operation is completed. As another preferred embodiment, during peak traffic hours, the monitoring and audible / visual warning mechanism 4 monitors in real time the frequency of traffic in the opposite lane of the designated right-turn guide lane in the specific parking area. The formula for calculating the frequency of traffic in the opposite lane is: f=M / T (2) In the formula: f represents the frequency of traffic in the opposite lane, in vehicles / second; M represents the number of vehicles passing through the opposite lane within the preset time interval, in vehicles; T represents the preset time interval, in seconds; A preset standard frequency threshold for oncoming lane traffic frequency is set. This threshold is determined based on factors such as the capacity of the guide lane and safe driving distance, for example, it is set to 0.1 vehicles / second. When the real-time monitored oncoming lane traffic frequency f exceeds the preset standard frequency threshold, for example, the real-time monitored frequency is 0.2 vehicles / second, it indicates that the traffic flow in the oncoming lane is large. In order to further reduce the driving range required for the vehicle to turn and reduce the risk of collision with vehicles in the oncoming lane, the minimum adjacent vehicle distance value for driving the vehicle to turn is adjusted to 1m. That is, when the real-time monitored minimum adjacent vehicle distance value reaches 1m, the turning operation is stopped. More preferably, a safe frequency threshold for the oncoming lane traffic frequency f is preset, which can be set to 0.05 vehicles / second. A tiered mechanism is introduced, that is, based on the real-time monitored oncoming lane traffic frequency f, the minimum adjacent vehicle spacing standard for steering vehicles is set in stages. Specifically, when the real-time monitored frequency of oncoming traffic f exceeds the preset standard frequency threshold of 0.1 vehicles / second, the minimum adjacent vehicle spacing value for driving the vehicle to turn is set to 1m. When the real-time monitoring of the oncoming lane traffic frequency f does not exceed the standard frequency threshold of 0.1 vehicles / second, but exceeds the safe frequency threshold of 0.05 vehicles / second, the minimum adjacent vehicle distance value for driving the vehicle to turn is set to 1.1m. When the real-time monitored oncoming lane traffic frequency f does not exceed the safe frequency threshold of 0.05 vehicles / second, the minimum adjacent vehicle spacing value for steering the vehicle is maintained at the upper limit of the basic standard range of 1.2m. During the reversing process, the monitoring and audible and visual warning mechanism 4 works continuously, monitoring the activity of people in the area, the minimum distance between adjacent vehicles, and the driving frequency of the opposite lane in real time. When it detects the presence of people in the area, the minimum distance between adjacent vehicles is lower than the set standard, or the driving frequency of the opposite lane changes, the monitoring and audible and visual warning mechanism 4 immediately sends a signal to the control module. The control module issues instructions to pause, adjust, or stop the reversing according to the actual situation, effectively ensuring the safety and reliability of the reversing process. By implementing this step, vehicle rerouting guidance can be automatically and accurately completed based on real-time monitoring data during peak traffic hours. This enables coordinated control of vehicle rerouting distances out of the depot, improving vehicle dispatch efficiency. At the same time, by setting rerouting standards in a tiered manner, the risk of vehicle collisions is reduced, ensuring traffic safety in the park. S4: When not in peak traffic hours, continue to adjust the vehicle to its initial state based on the parking space exit and relocation guidance and control system; The specific process is as follows: If the current time period is not within the determined peak traffic period, the off-peak working mode of the parking space exit relocation guidance and control system will be activated to relocate steel platform 1 and its corresponding vehicles to the initial state. The initial state is the original position of the steel bearing platform 1 before it is rotated or adjusted. At this time, the steel bearing platform 1 and its corresponding vehicle are in a square position, which makes it easier for vehicles to drive in and out of the parking space normally. Specifically, the reset procedure of the parking space exit direction guidance and control system is initiated. The control module sends a reverse drive command to the hydraulic cylinder mechanism 2 and the lead screw guide mechanism 3. The self-driving action of the hydraulic cylinder mechanism 2 and its corresponding adaptive displacement action of the lead screw guide mechanism 3 drive each group of steel bearing platform 1 to rotate and adjust in the reverse direction based on the support turntable 11, that is, to rotate and shift in the opposite direction to the direction adjustment during peak hours. During the reset process, the monitoring and audible and visual warning mechanism 4 continuously monitors the activity of people in the specific parking area and the distance between adjacent vehicles in real time. If people are detected in the area, a signal is immediately sent to the control module. The control module issues a pause command, the hydraulic cylinder mechanism 2 and the lead screw guide mechanism 3 stop working, and at the same time, the sound alarm and the flashing light alarm are activated to issue a warning message to remind people to stay away. After it is detected that there is no one in the area, the control module issues a continue command, and the reset operation continues. At the same time, the distance between adjacent vehicles is monitored in real time, and the control module adjusts the running speed of the hydraulic cylinder mechanism 2 and the lead screw guide mechanism 3 according to the monitored distance between the vehicles. That is, the smaller the distance between adjacent vehicles, the smaller the running speed, thereby improving the safety and stability of the reset process. When the steel support platform 1 returns to its initial set position, the support turntable 11, hydraulic cylinder mechanism 2 and screw guide rail mechanism 3 are all restored to their initial state. The control module issues a command to stop the drive, completing the adjustment operation of the vehicle turning back to its initial state. At this time, the monitoring and audible and visual warning mechanism 4 continues to monitor the situation of the specific parking area, providing safety assurance for the next turning operation or the entry and exit of the vehicle.

[0034] By implementing this step, vehicles are redirected to their initial state during off-peak hours, ensuring the ease of use of parking spaces during regular periods, meeting normal parking and exit needs during off-peak hours, and laying the foundation for redirection guidance during the next peak period, thus ensuring the continuous stability of the entire control system.

A method for intelligent outbound rerouting guidance based on regionalized traffic flow control in a park, characterized in that, Includes the following steps: Obtain information on peak traffic hours and congested parking spaces within the park; Based on the location of congested parking spaces, a regionalized parking space exit guidance and control system will be established. During peak traffic hours, the vehicle relocation control system assists in completing vehicle relocation control based on the parking space exit relocation guidance and control system; When it is not during peak traffic hours, continue to adjust the vehicles to their initial state based on the parking space exit and relocation guidance and control system. The acquisition of peak traffic hours and congested parking spaces within the park specifically includes: Traffic flow monitoring equipment is deployed at road intersections, parking lot entrances and exits, and parking areas within the park to collect real-time vehicle traffic and parking data for each area of ​​the park within a preset period. The collected vehicle traffic data and parking data are transmitted to the data processing center, where data cleaning algorithms are used to preprocess the data and remove abnormal and redundant data. Next, the preprocessed vehicle traffic data was analyzed to calculate the vehicle traffic density for each time period within a specific monitoring area. The formula for calculating vehicle traffic density is as follows: ρ=N / (L×W) (1) In the formula: ρ represents vehicle traffic density, in units of vehicles / square meter; N represents the number of vehicles passing through a specific monitoring area within a preset time period, in units of vehicles; L represents the road length of the specific monitoring area, in units of meters; W represents the road width of the specific monitoring area, in units of meters; A preset vehicle traffic density threshold is set, and the vehicle traffic density of each time period is compared with the preset density threshold. The time periods when the vehicle traffic density exceeds the preset density threshold are selected and determined as peak traffic periods. The preprocessed parking data is analyzed to calculate the vehicle dwell time and exit waiting time for each parking space. The vehicle dwell time is the difference between the time it takes for a vehicle to enter the parking space and the time it takes to leave the parking space; the exit waiting time is the difference between the time it takes for a vehicle to start its exit and the time it actually leaves the parking space. The system sets a threshold for vehicle dwell time and a threshold for waiting time to exit.

The aforementioned system for guiding and controlling parking space exits based on congested parking spaces is regionalized and includes: For a given congested parking space, it is divided into several specific parking areas. Each specific parking area contains several groups of parking spaces. For each group of parking spaces in each specific parking area, a steel support platform is pre-configured, and the size of the steel support platform matches the size of its corresponding parking space.

Specifically, it includes: Determine whether a specific parking area meets the conditions for turning around and driving. The specific conditions for turning around and driving include no human activity in the area and the minimum distance between adjacent vehicles being higher than the predetermined standard range. When the specific parking area is determined to meet the turning drive conditions, the control module sends a drive command to the hydraulic cylinder mechanism and the lead screw guide mechanism. The hydraulic cylinder mechanism's own driving action and its corresponding adaptive displacement action to the lead screw guide mechanism work together to drive each group of steel bearing platforms to synchronously rotate and turn based on the support turntable. The method for setting the specific steering parameters of the rotation adjustment includes: The basic standard range for the minimum adjacent vehicle spacing is 1~1.2m, and the minimum adjacent vehicle spacing between vehicles in this specific parking area is monitored in real time by the monitoring and sound and light warning system. When the real-time monitored minimum adjacent vehicle spacing value reaches the upper limit of the basic standard range of 1.2m, it is determined that the current rotation angle of the steel bearing platform meets the standard angle state of the current single-turn control. The control module issues a stop command, the hydraulic cylinder mechanism and the lead screw guide mechanism stop working, and the turning operation is completed.
