Description

Technical Field

[0001] The present invention relates to the technical field of bus stop guidance systems, and more specifically, to an intelligent bus stop guidance system. Background Art

[0002] The bus stop guidance system is an intelligent solution that uses advanced technology to improve the efficiency and safety of bus stops. This system usually combines video surveillance, artificial intelligence analysis, real-time data processing and interactive display technology to achieve precise management and guidance of passenger flow. Through the intelligent guidance system, passengers can obtain real-time vehicle arrival information, platform congestion, and recommendations for the best boarding points, thereby optimizing passenger distribution and reducing waiting time. In addition, the system can adjust the frequency of bus departures and vehicle allocation through predictive algorithms, further improving the efficiency and responsiveness of the entire bus network.

[0003] Although bus stop guidance systems offer many advantages, traditional bus stops still face a series of challenges. First, the problem of passenger congestion is particularly prominent during peak hours, which easily leads to passengers waiting in crowded places at the platform, increasing the risk of accidents and affecting the riding experience. Secondly, the phenomenon of disorderly boarding is common, that is, passengers do not board the bus in the prescribed order, which not only causes low efficiency, but also may cause disputes and chaos. Standardizing passengers' riding habits is an important and complex issue. The phenomenon of disorderly boarding and non-compliance with queuing rules is common, which not only affects the operating efficiency of the public transportation system, but also reduces the riding experience, and sometimes may cause verbal disputes or even physical conflicts. In addition, some passengers may choose to forcibly board the bus in an unsafe position or get on and off the bus when the vehicle is not completely stopped because they are in a hurry or for other personal reasons, which greatly increases safety risks.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an intelligent bus stop guidance system. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent bus stop guidance system to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] An intelligent bus stop guidance system, comprising:

[0008] Blocking device: It is installed on the platform of the bus station and is used to automatically rise when the bus enters the platform to form the only boarding passage;

[0009] Projection device: installed at the bus station and working synchronously with the bus door, used to project multiple designated boarding areas on the ground when the bus door is open, to monitor whether passengers are boarding in a standardized manner;

[0010] Control module: connected to the bus and the platform, managing the operation of the blocking device and the projection device;

[0011] Positioning module: used to accurately locate buses and bus stops for route planning;

[0012] Display module: displays real-time bus information and ride guidance information to help passengers understand the ride process;

[0013] Crowd analysis module: Analyze the density and movement trend of the crowd on the platform, and adjust the setting of the boarding area and the use of blocking devices.

[0014] As a further improvement of the present invention, the blocking device is any one of an automatic telescopic door and a fence, which can be automatically controlled to be telescopic according to the arrival and departure of the bus.

[0015] As a further improvement of the present invention, the projection device can project different numbers of passenger areas according to passenger requirements, and each area corresponds to a specific door.

[0016] As a further improvement of the present invention, the intelligent bus stop guidance system includes a central processing unit for receiving vehicle arrival signals and passenger data, and adjusting the working states of the blocking device and the projection device accordingly. The specific operation is as follows: when the central processing unit receives the vehicle arrival signal, the blocking device is controlled to automatically rise to restrict the entry of passengers in non-designated areas; at the same time, the number, size and position of the boarding areas generated by the projection device are dynamically adjusted according to real-time passenger data to optimize the boarding process and reduce congestion.

[0017] As a further improvement of the present invention, the intelligent bus stop guidance system further comprises:

[0018] Alarm module: used to send out warning signals when it detects that passengers do not comply with riding rules.

[0019] As a further improvement of the present invention, when the alarm module detects that a passenger cuts in line or fails to follow the projected instructions to enter a non-designated boarding area, it can activate a blocking device. The blocking device specifically prevents the offending passenger from further movement by extending an additional fence portion. At the same time, the alarm module will issue visual and sound warnings to remind passengers to return to the designated boarding area to maintain order and safety in the boarding.

[0020] As a further improvement of the present invention, the intelligent bus stop guidance system further comprises:

[0021] The passenger credit score module is used to record each passenger's riding behavior and increase or decrease the credit score based on good or illegal behavior.

[0022] As a further improvement of the present invention, when the passenger credit score of a passenger recorded in the passenger credit score module reaches a certain lower threshold, the passenger will be temporarily prohibited from using the bus service.

[0023] As a further improvement of the present invention, the moving part of the blocking device is equipped with a safety protective cover containing electrorheological fluid. The protective cover is filled with electrorheological fluid, which maintains low viscosity when not powered, so that the protective cover remains soft to prevent accidental injury to passengers when the blocking device moves. When the blocking device reaches a predetermined position, current is applied to the electrorheological fluid to quickly transform it into a high-viscosity gel, thereby enhancing the hardness and structural stability of the protective cover, thereby effectively achieving a strong blocking function and ensuring the safety of passengers.

[0024] As a further improvement of the present invention, the blocking device has an intelligent sensing function and can detect objects in the movement direction of the blocking device. When an object is detected, the blocking device will automatically stop moving or move slowly to avoid causing harm to passengers on the platform. In addition, the system prompts the operating blocking status through visual or sound signals to enhance the safety awareness of passengers.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] The intelligent bus stop guidance system in this solution effectively solves many challenges faced by traditional bus stops by integrating highly automated technical components, especially the problems of crowded and disorderly passenger boarding during peak hours. The system ensures that passengers get on and off the bus in an orderly manner through automatic telescopic doors or barriers, while the projection equipment adjusts the projection area according to the real-time passenger flow to clearly indicate the appropriate boarding area. This configuration not only optimizes passenger flow and reduces crowding, but also significantly improves the efficiency and safety of boarding. In particular, when the system's alarm module detects that a passenger cuts in line or fails to enter a non-designated boarding area as instructed, it will automatically activate the blocking device and issue visual and sound warnings to force passengers to return to the designated area, thereby directly reducing disputes and confusion caused by disorderly boarding and significantly improving the riding experience. In addition, the credit score mechanism records the behavior of each passenger and punishes violations, such as reducing the credit score, and restricting the passenger's boarding privileges when the credit score is too low, further standardizing the behavior of passengers and educating passengers to abide by public transportation rules, thereby improving the overall operating efficiency and passenger satisfaction of the public transportation system in the long term.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] Example:

[0033] See also Figure 1-4 , an intelligent bus stop guidance system, comprising:

[0034] Blocking device: It is installed on the platform of the bus station and is used to automatically rise when the bus enters the platform to form the only boarding passage;

[0035] Projection device: installed at the bus station and working synchronously with the bus door, used to project multiple designated boarding areas on the ground when the bus door is open, to monitor whether passengers are boarding in a standardized manner;

[0036] Control module: connected to the bus and the platform, managing the operation of the blocking device and the projection device;

[0037] Positioning module: used to accurately locate buses and bus stops for route planning;

[0038] Display module: displays real-time bus information and ride guidance information to help passengers understand the ride process;

[0039] Crowd analysis module: Analyze the density and movement trend of the crowd on the platform, and adjust the setting of the boarding area and the use of blocking devices.

[0040] Among them, by integrating highly automated components and modules, the operational efficiency and safety of bus stops are improved, the boarding process is optimized, and the passengers' riding experience is improved and the passengers' bad riding habits are standardized. The system mainly includes six core components, each of which is specially designed to solve specific problems in bus stop operations.

[0041] The blocking device is a key part of the system and is installed on the platform of the bus station. When the bus enters the platform, the device automatically rises, effectively forming a single boarding channel. It is designed to control how and when passengers enter the bus, prevent crowding and disorderly boarding, and improve safety.

[0042] The projection device works synchronously with the bus door, and is responsible for projecting multiple designated boarding areas on the platform floor when the bus door is opened. These areas clearly indicate where passengers should stand, thereby guiding passengers to board the bus in a standardized manner and reducing confusion.

[0043] The control module connects the bus to the station and manages the operation of the blocking and projection devices. By receiving signals from the bus, the system can activate or adjust these devices in a timely manner to ensure their correct operation and efficient coordination.

[0044] The positioning module is used to accurately locate the location of buses and passengers, and supports route planning between bus stops and buses. Through high-precision positioning technology, the location of buses and estimated arrival times are monitored in real time, thereby optimizing bus routes and station scheduling plans.

[0045] The display module displays real-time bus information and boarding guidance information on the platform. This information helps passengers understand upcoming vehicle information, boarding rules and platform status, improving passengers' information transparency and riding experience.

[0046] The crowd analysis module analyzes the density and movement trends of people on the platform and adjusts the setting of the boarding area and the use of blocking devices based on real-time data. The purpose of this module is to dynamically optimize the distribution of people flow, reduce congestion, and speed up boarding.

[0047] The blocking device is any one of an automatic telescopic door and a fence, which can be automatically controlled to be telescopic according to the arrival and departure of the bus.

[0048] The projection device can project different numbers of passenger areas according to passenger requirements, and each area corresponds to a specific door.

[0049] Among them, the automatic telescopic doors and fences are used to control the entry and exit of passengers, ensuring order and safety when the bus arrives and leaves the station. Sensors (such as infrared sensors, pressure sensors or cameras) can be used to detect the arrival of the bus. When the system confirms through the sensor that the bus has arrived and stopped, the automatic telescopic door or fence receives the signal and automatically opens to allow passengers to get on and off the bus. After the bus leaves, the sensor triggers the signal again, and the door or fence automatically closes to prevent passengers from entering the lane or dangerous area at will.

[0050] The projection device projects different numbers and locations of boarding areas according to different riding needs. Each area corresponds to a specific door on the bus, optimizing passenger flow and reducing boarding time. High-brightness projection equipment can be used to clearly project the markings of the boarding areas on the ground or other planes. In conjunction with the vehicle positioning system and on-board sensors, it ensures that the position of each projection corresponds accurately to the actual position of the bus door.

[0051] The projection equipment receives data from the vehicle and passenger flow monitoring system and dynamically adjusts the number and location of projections according to real-time demand. During periods of high passenger volume or when the vehicle is fully loaded, the system can adjust the projection area to maximize processing capacity and efficiency.

[0052] It can be integrated into an intelligent traffic management system to optimize its performance through big data analysis and machine learning algorithms. Through automated control, it can significantly improve safety and efficiency, reduce human errors and accidents, improve passenger satisfaction, reduce waiting and boarding time, and improve overall traffic mobility.

[0053] The intelligent bus stop guidance system includes a central processing unit for receiving vehicle arrival signals and passenger data, and adjusting the working states of the blocking device and the projection device accordingly. The specific operations are as follows: when the central processing unit receives the vehicle arrival signal, the blocking device is controlled to automatically rise to restrict the entry of passengers in non-designated areas; at the same time, the number, size and position of the boarding areas generated by the projection device are dynamically adjusted according to real-time passenger data to optimize the boarding process and reduce congestion.

[0054] The purpose of the central processing unit is to receive and process arrival signals and passenger data from the vehicle, analyze the data in real time, and adjust the configuration of the blocking device and the projection device based on the vehicle arrival situation and passenger flow. Usually, GPS tracking or on-board sensors send data to the central processing unit in real time to ensure accurate monitoring of the location and arrival time of the bus.

[0055] Data on passenger numbers and flow patterns can be collected through cameras, infrared sensors or other people counting devices on the platform. The data helps the system assess demand for rides and thus optimize the layout of the projection area.

[0056] When the bus approaches the platform, the arrival signal sent by the vehicle is received by the central processing unit, and the CPU immediately processes the signal and starts to initiate subsequent control commands. According to the vehicle arrival signal, the CPU controls the automatic retractable door or fence to rise to prevent passengers from entering non-designated boarding areas. This measure ensures that passengers queue up safely and orderly to wait for the bus.

[0057] The central processing unit analyzes real-time passenger data and dynamically adjusts the boarding areas generated by the projection equipment according to current demand, including the number, size and location of the boarding areas, aiming to maximize the use of space and reduce congestion and waiting time.

[0058] Through intelligent adjustment, the system ensures that each passenger area can be efficiently matched with the corresponding door, improving the efficiency of boarding and alighting. The system can also adjust the projection area according to slight changes in the actual arrival position of the vehicle to ensure accurate correspondence.

[0059] The intelligent bus stop guidance system further comprises:

[0060] Alarm module: used to send out warning signals when it detects that passengers do not comply with riding rules.

[0061] When the alarm module detects that a passenger cuts in line or fails to follow the projected instructions to enter a non-designated boarding area, it can activate the blocking device. The blocking device specifically prevents the offending passenger from further movement by extending an additional fence portion. At the same time, the alarm module will issue visual and sound warnings to remind passengers to return to the designated boarding area to maintain order and safety on the ride.

[0062] The alarm module is designed to monitor whether passengers enter the designated boarding area in accordance with regulations. Once a violation is detected, such as a passenger cutting in line or entering a non-designated boarding area, the module triggers the corresponding warning and physical blocking measures. Passenger behavior is monitored in real time through technologies such as video surveillance, infrared sensors or pressure sensing devices. The passenger's location and movement trajectory can be accurately identified to determine whether any violation has occurred.

[0063] When a passenger violation is detected, the alarm module first issues a visual and audible warning. The visual warning may include flashing lights or text prompts on the LED screen. The audible warning is issued through the speaker to remind the passenger to pay attention and correct his or her behavior.

[0064] If the passenger continues the illegal behavior despite the initial warning, the alarm module will command the blocking device to respond. The blocking device may physically prevent the passenger from further movement by extending additional fence sections to ensure that the passenger returns to the designated boarding area.

[0065] The alarm module records the incidents and provides data support for station management and future improvements. This data can help analyze common patterns and causes of violations and further optimize station design and signage.

[0066] The alarm module is tightly integrated with the central processing unit, projection device and blocking device to ensure that all parts work together to achieve a fast and consistent response. By preventing illegal passengers from taking action, the system effectively reduces the potential safety hazards caused by passenger crowding or conflict. Ensuring that all passengers board the bus in an orderly manner within the designated area can significantly improve bus loading efficiency and reduce stop time.

[0067] The system is not only for restriction, but also for educating passengers to abide by public transportation rules through real-time feedback and improving the overall riding culture. It not only improves the operational efficiency of public transportation, but also enhances the sense of security of passengers. In addition, in this way, it is possible to gradually improve the behavioral norms in public places and promote a more civilized riding environment.

[0068] The intelligent bus stop guidance system further comprises:

[0069] The passenger credit score module is used to record each passenger's riding behavior and increase or decrease the credit score based on good or illegal behavior.

[0070] When the passenger credit score of a passenger recorded in the passenger credit score module reaches a certain lower threshold, the passenger will be temporarily prohibited from using the bus service.

[0071] Among them, each passenger is identified through identity authentication equipment (such as card swiping machines, face recognition systems, etc.). This requires passengers to have a registered account when using public transportation services, in which personal information and riding records are recorded.

[0072] Combined with the aforementioned alarm module, it monitors whether passengers comply with the rules of riding (such as whether they wait in the designated area, whether they cut in line, etc.). These data are collected by cameras, sensors and other equipment and analyzed by the central processing unit. The credit score is automatically increased or decreased according to the passenger's behavior. Good behavior (such as complying with the rules of riding, courtesy to the elderly, the weak, the sick and the disabled, etc.) can increase the score, while violations will deduct points.

[0073] The specific rules for increasing and decreasing credit points need to be fair and transparent to ensure that passengers can accept and understand them. When a passenger's credit score drops below a certain threshold, the system will automatically restrict their access to bus services. Temporary bans or other restrictions can be set, such as limiting the use of bus services during peak hours.

[0074] The reputation score module is tightly integrated with other systems such as the central processing unit, payment system, customer service, etc., ensuring real-time update and effective application of information. Passengers can check their reputation score through the mobile app, website or on-site service desk and receive suggestions on how to improve their behavior. This also provides an opportunity to provide feedback on the system to ensure fairness and improvement.

[0075] Passenger behavior monitoring and credit scoring involve a large amount of personal data, and relevant data protection regulations must be strictly followed to ensure that passengers' privacy is not violated. Provide a transparent operating mechanism and credit rating criteria, and passengers should be able to file complaints about changes in credit scores and have them reviewed through a fair process.

[0076] By implementing such a passenger credit score module, not only can the efficiency and order of public transportation be improved, but more civilized riding behaviors can also be encouraged, thereby improving the service quality and passenger satisfaction of the entire public transportation system.

[0077] The moving part of the blocking device is equipped with a safety protective cover containing electrorheological fluid. The protective cover is filled with electrorheological fluid. The liquid maintains low viscosity when not powered, so that the protective cover remains soft to prevent accidental injury to passengers when the blocking device moves. When the blocking device reaches the predetermined position, current is applied to the electrorheological fluid to quickly transform it into a high-viscosity gel, enhancing the hardness and structural stability of the protective cover, thereby effectively realizing a solid blocking function and ensuring passenger safety.

[0078] The blocking device has an intelligent sensing function and can detect objects in the direction of movement of the blocking device. When an object is detected, the blocking device will automatically stop moving or move slowly to avoid causing harm to passengers on the platform. In addition, the system uses visual or sound signals to indicate the operating blocking status to enhance passengers' safety awareness.

[0079] Among them, in this intelligent bus stop guidance system, one of the key components of the blocking device is the safety protective cover containing electrorheological fluid equipped on its moving part. The core material of the protective cover, electrorheological fluid, has low viscosity when not powered, making the protective cover soft and flexible. This design is mainly to prevent hard collisions when the blocking device is in motion, thereby minimizing the potential risk of injury to passengers on the platform.

[0080] When the blocking device completes its movement and reaches the predetermined position, the system will automatically apply current to the electrorheological fluid. At this time, the viscosity of the electrorheological fluid will increase rapidly and become gel-like, thereby significantly enhancing the hardness and structural stability of the protective cover. This state conversion allows the protective cover to provide the necessary structural support when a solid barrier is required, ensuring that the blocking device effectively performs its function, while maintaining its safety for passengers when it is not needed.

[0081] The projection device and monitoring equipment in the system monitor the boarding area in real time, automatically detect queue-jumping behavior and trigger a response. Once queue-jumping is detected, the intelligent blocking device quickly moves to the corresponding area, and the electrorheological fluid inside it quickly hardens after power is turned on, forming a solid barrier that effectively blocks queue-jumping passengers. This mechanism not only responds quickly to ensure passenger safety, but also maintains order at the bus stop through physical blocking, greatly improving riding efficiency and passenger experience. In addition, the system helps educate passengers to abide by riding rules, thereby improving the overall operating efficiency and passenger satisfaction of the public transportation system in the long term.

[0082] In addition, the blocking device also has advanced intelligent sensing functions, which can detect any object in the direction of its movement. This function is achieved through sensors installed on the blocking device (such as infrared sensors, ultrasonic sensors, etc.). When the sensor detects a human body or other objects, the blocking device will automatically stop moving or continue moving at a slower speed to avoid collision damage.

[0083] The system is also equipped with a set of visual and sound signal warning systems to enhance passengers' safety awareness. When the blocking device starts to move or changes state, the system will display a warning message on the platform display and issue a warning sound through the speaker to remind passengers of the ongoing operation and ensure that passengers stay away from possible danger areas.
