Description

Technical Field

[0001] The present application relates to the field of digital road technology, and more specifically, to a digital road driving system for a smart park. Background Art

[0002] As various parks continue to develop, the number of vehicles in the parks is increasing, which poses a severe challenge to the road management of the parks.

[0003] Traditional park traffic management methods mostly rely on manual command and simple signs to guide vehicles, which has many drawbacks. As a result, in park traffic management, problems such as large trucks occupying the road and obstructing the normal passage of other vehicles, foreign vehicles mistakenly entering sensitive internal areas, and vehicles driving disorderly on one-way streets causing traffic jams often occur.

[0004] Therefore, a reasonable road driving system is urgently needed to improve the current traffic management status of the park and improve the overall traffic operation efficiency and safety of the park.

[0005] To this end, this application proposes a smart park digital road driving system to solve the above-mentioned problems.

[0006] Application Contents

[0007] In order to solve the above problems, the present application provides a smart park digital road driving system.

[0008] The digital road driving system for a smart park provided in this application adopts the following technical solutions:

[0009] A digital road driving system for a smart park, characterized in that it comprises: a license plate recognition module, a guide light, a visual recognition module, an information storage module, a central control module, a road condition monitoring module, and a vehicle state perception module; the license plate recognition module, the guide light, the visual recognition module, the information storage module, the road condition monitoring module, the vehicle state perception module, and the emergency processing module are respectively connected to the central control module through a wireless communication module;

[0010] The license plate recognition module is set at the park entrance and key road nodes inside the park, and is used to collect license plate images of passing vehicles and recognize license plate numbers, and compare the recognized license plate information with the data in the information storage module to determine whether the vehicle is an internal vehicle;

[0011] The information storage module pre-stores the license plate numbers and vehicle types of vehicles within the park;

[0012] The guide lights are arranged at intervals along both sides of the park road, and the guide lights display states to convey different driving guidance information;

[0013] The visual recognition module is arranged at the entrance and exit of the park, and is used to capture the driving status, visual outline and vehicle model characteristics of the vehicle to determine the vehicle type and feed back the relevant information to the central control module;

[0014] The road condition monitoring module is used to collect information about the park roads, including road conditions and weather conditions, in real time, and feed it back to the central control module;

[0015] The vehicle state sensing module is installed near the vehicle passage section. The vehicle state sensing module senses the vehicle speed, vehicle distance, and vehicle condition, and sends the sensed data to the central control module.

[0016] The central control module receives information from the license plate recognition module, the visual recognition module, the road condition monitoring module, and the vehicle status perception module, analyzes and processes the information in combination with the preset rules and data in the information storage module, and generates guidance instructions to control the guide lights to display the corresponding display status to guide the vehicle.

[0017] Furthermore, the display content of the guide light includes color, flashing and arrow, wherein the colors include at least green, yellow and red, and the flashing modes include constant light, fast flashing and slow flashing.

[0018] Through the above technical solution, the display content and specific mode of the guide lights are clarified. Through a combination of multiple colors, flashing modes and arrow indications, rich, clear and intuitive guidance information can be provided to vehicles, so that drivers can quickly and accurately understand the driving guidance intentions conveyed by the system, which helps to improve the efficiency of vehicle traffic within the park and reduce traffic congestion caused by unclear guidance.

[0019] Furthermore, the road condition monitoring module includes a sensor array arranged on the surface and periphery of the park road, and the sensor array includes at least a road surface humidity sensor, a temperature sensor, an ice detection sensor and a weather station; the road surface humidity sensor is used to detect whether the road surface is wet; the temperature sensor is used to monitor the road surface temperature; the ice detection sensor determines whether the road surface is frozen; the weather station collects real-time meteorological information in the park, including wind speed, wind direction, and precipitation.

[0020] Through the above technical solution, the road condition monitoring module is equipped with a variety of sensor arrays, which can comprehensively and in real time collect key information such as the road conditions and weather conditions of the park roads. This allows park managers and the central control module to grasp the actual road conditions in advance, so as to take timely response measures to ensure the safe driving of vehicles under different road conditions and weather conditions. It also helps to reasonably plan vehicle routes and avoid traffic jams or accidents caused by bad road conditions.

[0021] Furthermore, when the license plate recognition module identifies the vehicle as an internal vehicle, the central control module plans a reasonable driving route based on the distribution of internal parking spaces in the information storage module and the current traffic conditions of the road, and guides the vehicle to an empty internal parking space by controlling the guide lights along the way to light up in a predetermined order so that they are always green and have an arrow pointing in the direction of the parking space.

[0022] Through the above technical solution, for internal vehicles, the central control module can plan a reasonable route based on the distribution of parking spaces and real-time traffic conditions, and accurately guide vehicles to vacant internal parking spaces through guidance lights. This can optimize the parking process of internal vehicles, reduce the time for vehicles to find parking spaces, and improve the utilization rate of parking spaces in the park. At the same time, it can also maintain the orderliness of internal traffic in the park and avoid congestion caused by random parking of vehicles.

[0023] Furthermore, when the road condition monitoring module is combined with the road condition information fed back by the road condition monitoring module, when encountering a section of road with bad road conditions, the guide light is used to prompt the vehicle to slow down or change the driving route in advance.

[0024] Through the above technical solution, combined with road condition information, the vehicle is prompted to slow down or change the driving route, which fully considers the impact of bad road conditions on vehicle driving safety. It can effectively reduce the risk of vehicle accidents under special road conditions, ensure the safety of people in the vehicle, and help maintain the normal traffic order of the road to avoid further deterioration of traffic congestion caused by poor road conditions.

[0025] Furthermore, the license plate recognition module identifies that the vehicle is a foreign vehicle. The central control module controls the guide lights on the corresponding roadside to flash yellow and indicate the direction of the visitor parking space according to the location of the visitor parking space and the current location of the foreign vehicle, guiding it to the area where the visitor parking space is located, and uses the visual recognition module to monitor the surrounding conditions of the foreign vehicle in real time to prevent it from entering sensitive areas inside the park.

[0026] Through the above technical solution, foreign vehicles can not only be guided to visitor parking spaces, but also monitored in real time with the help of visual recognition modules to prevent them from entering sensitive areas. This precise guidance and prevention mechanism not only facilitates parking for foreign visitors and improves visitor experience, but also ensures the safety of sensitive areas within the park, maintains the normal operation and management order of the park, and avoids safety hazards and management problems caused by foreign vehicles accidentally entering.

[0027] Furthermore, when there is a one-way street inside the park, the central control module continuously receives the vehicle flow and driving direction information on the one-way street fed back by the visual recognition module. When a vehicle is found driving in a direction that may cause congestion, the guide light in that direction is controlled to flash red to indicate that passage is prohibited, and a green arrow is lit to indicate the passable direction, thereby guiding vehicles to travel in a reasonable direction and avoiding traffic jams.

[0028] Through the above technical solution, when there is a one-way street in the park, the central control module adjusts the guide lights in real time according to the vehicle flow and driving direction information to prevent vehicles from driving in the direction of congestion. This is conducive to maintaining smooth traffic on one-way streets, improving the traffic efficiency of one-way streets, preventing traffic jams caused by illegal behaviors such as vehicles driving in the opposite direction, and ensuring the orderly operation of the entire park's transportation network.

[0029] Furthermore, combined with the road condition information transmitted by the road condition monitoring module, when water accumulation and ice formation affect the normal traffic on the one-way street, the guidance strategy is adjusted in time to guide vehicles to take detours.

[0030] Through the above technical solution, the one-way street guidance strategy can be adjusted in time in combination with road condition information. When the road is flooded, iced, or other conditions that affect traffic are encountered, vehicles are guided to take detours. This can minimize the impact of adverse road conditions on one-way traffic, ensure that vehicles can pass through the one-way area in the park safely and smoothly, and avoid vehicle backlogs and impassability on the one-way street due to road conditions.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] (1) Through the coordinated work of various modules and the intelligent regulation of the central control module, the system can accurately guide different types of vehicles, reasonably plan driving routes, and effectively reduce the occurrence of vehicles looking for parking spaces, road congestion, and illegal driving, thereby improving the overall traffic efficiency within the park and optimizing the traffic management order of the park;

[0033] (2) With the help of multi-dimensional information collected by the visual recognition module, road condition monitoring module, and vehicle status perception module, the system can perceive potential traffic risks in advance and guide vehicles to respond accordingly through guide lights in a timely manner, thereby reducing the probability of accidents, ensuring the safety of people, vehicles, and important areas in the park, and maintaining a stable and orderly operating environment in the park.

This allows park managers and central control modules to grasp the actual road conditions in advance, so as to make timely response measures to ensure the safe driving of vehicles under different road conditions and meteorological environments. It also helps to reasonably plan vehicle routes to avoid traffic jams or accidents caused by bad road conditions.

[0048] See also Figure 1 When the license plate recognition module identifies the vehicle as an internal vehicle, the central control module plans a reasonable driving route based on the internal parking space distribution in the information storage module and the current road traffic conditions, and guides the vehicle to the vacant internal parking space by controlling the guide lights along the way to light up in a predetermined order with a green steady light and an arrow pointing in the direction of the parking space; for internal vehicles, the central control module can plan a reasonable route based on the parking space distribution and real-time traffic conditions, and accurately guide the vehicle to the vacant internal parking space through the guide lights. This can optimize the parking process of internal vehicles, reduce the time for vehicles to find parking spaces, and improve the utilization rate of parking spaces in the park.

It can effectively reduce the risk of vehicle accidents under special road conditions, ensure the safety of people in the car, and help maintain the normal traffic order of the road to avoid further deterioration of traffic congestion caused by poor road conditions.

[0050] See also Figure 1 , the license plate recognition module identifies the vehicle as a foreign vehicle. The central control module controls the corresponding roadside indicator light to flash yellow and indicate the direction of the visitor parking space according to the location of the visitor parking space and the current location of the foreign vehicle, guiding it to the visitor parking space area, and monitors the surrounding conditions of the foreign vehicle in real time through the visual recognition module to prevent it from entering sensitive areas inside the park; for foreign vehicles, it can not only guide them to the visitor parking space, but also use the visual recognition module to monitor in real time to prevent them from entering sensitive areas. This precise guidance and prevention mechanism not only facilitates parking for foreign visitors and improves the visitor experience, but also ensures the safety of sensitive areas inside the park, maintains the normal operation and management order of the park, and avoids safety hazards and management problems caused by foreign vehicles accidentally entering.

[0051] See also Figure 1 When there is a one-way street inside the park, the central control module continuously receives the vehicle flow and driving direction information on the one-way street from the visual recognition module.

[0053] It should be noted that the license plate recognition module, guide light, visual recognition module, information storage module, central control module, road condition monitoring module, and vehicle status perception module mentioned in this application are all existing mature technologies. This application does not protect any one of these technologies, but the technical effects achieved by the combination of multiple technologies and modules.

[0054] The implementation principle of a digital road driving system for a smart park in the present application embodiment is as follows:

[0055] The entire smart park digital road driving system is centered on the central control module, and each module works together. First, the license plate recognition module collects images of passing vehicles’ license plates at the park entrance and key road nodes and identifies the numbers, and compares them with the data in the information storage module to determine the vehicle attributes, such as whether it is an internal vehicle.

[0056] The visual recognition module is arranged at the entrance and exit of the park to capture information such as the vehicle's driving status, appearance outline and vehicle model characteristics, assist in determining the vehicle type, and feed this information back to the central control module.

[0057] The road condition monitoring module uses the various sensors it contains to collect real-time information on the road conditions and weather conditions of the park roads, and also feeds back to the central control module.

[0058] The vehicle status sensing module is installed near the vehicle traffic section, senses the vehicle speed, distance between vehicles, vehicle status and other data and sends them to the central control module.

[0059] After receiving the information from the above modules, the central control module conducts comprehensive analysis and processing based on the rules and data pre-set in the information storage module, such as the distribution of internal parking spaces in the park, the location of visitor parking spaces, road traffic rules, and the scope of sensitive areas.

[0060] For example, if it is identified as an internal vehicle, the route will be planned according to the parking space situation and current traffic conditions, and the guide lights along the way will be controlled to light up green in a predetermined order with an arrow pointing to the parking space to guide the vehicle to an empty parking space; if it is an external vehicle, the guide lights will be driven to flash yellow and indicate the direction of the visitor parking space to guide it to the corresponding parking space, and the visual recognition module will monitor it to prevent it from entering sensitive areas; in a one-way street scenario, according to the vehicle flow and driving direction information as well as the road condition information, the guide lights will be controlled to flash red to indicate prohibited passage or light up green arrows to indicate the passable direction, so as to guide the vehicle to drive reasonably; at the same time, when encountering severe road conditions, according to the feedback from the road condition monitoring module, the guide lights will be used to prompt the vehicle to slow down or change the driving route, thereby achieving comprehensive and intelligent guidance of vehicles in the park and ensuring the orderly, safe and efficient operation of the park traffic.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
