Description

Technical Field

[0001] The present application relates to the field of intelligent transportation technology, and in particular to a city bus boarding and alighting safety assistance system. Background Art

[0002] With population growth, urban traffic pressures are increasing dramatically. Peak-hour congestion and overcrowded buses pose potential risks to urban public safety. In recent years, energy-saving, environmentally friendly, new energy buses with unmanned ticketing have been put into widespread use. Drivers are focused on driving, leaving no one on board to monitor bus overloads or the surrounding environment as passengers board and alight. Passengers are unable to predict the current capacity of their bus, resulting in congestion or vacant seats, and an imbalance in passenger capacity. Furthermore, passengers are unable to predict oncoming vehicles from behind when alighting, leading to various traffic accidents and threats to passenger safety. Summary of the Invention

[0003] In view of this, the purpose of this application is to propose a city bus boarding and alighting safety assistance system.

[0018] Furthermore, the human-computer interaction module includes: a first display screen, a second display screen, a first speaker and a second speaker.

[0019] Furthermore, after the vehicle stops, the on-board terminal module is specifically configured to fuse the video image information collected by the vehicle's front camera, the vehicle's rear camera and the vehicle's external right camera, and display it through the human-computer interaction module.

[0020] Furthermore, after the vehicle stops, the vehicle terminal module is specifically configured to:

[0021] Processing the video image information collected by the right side camera outside the vehicle to identify the target dangerous vehicle;

[0036] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0037] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs. The "first", "second" and similar words used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] As mentioned in the background, public transportation plays a crucial role in alleviating urban traffic pressure and improving the traffic environment. Buses, as a form of public transportation, are a crucial means of transportation for citizens. However, during peak bus operations, passengers often crowd and board buses, forcing their way onto buses, causing extreme congestion. This can prevent doors from closing properly, impacting operations and even causing accidents. Furthermore, during bus operations, standing areas are prohibited at the front and rear doors, and passengers often stand, posing a serious safety hazard when opening and closing the doors.

[0039] During operation, passengers have no access to information about the number of passengers on board the route's vehicles, including arrival information. During peak hours, passengers often rush to board the bus as it arrives, resulting in a packed bus and a sparsely populated next bus or bus. Upon arrival, the driver pulls over to the roadside for passengers to board and disembark. Since passengers are unaware of the surrounding environment, collisions with passing motorcycles, electric bikes, and bicycles are common.

[0040] Based on the above situation, it is of great significance to develop a reliable boarding and alighting safety assistance system to provide prompt information to passengers and avoid traffic accidents. The present invention provides a city bus boarding and alighting safety assistance system, which calculates the number of passengers in the bus, and provides information on the bus schedule and the number of passengers on the bus for passengers waiting to board the bus. This system can provide a reference for passengers to board the bus, prevent passengers from crowding, forcing the bus and causing the door to be unable to be closed, and reduce boarding safety accidents. When the vehicle arrives at the station, the area where the door is easily pinched is monitored and displayed on the display screen in the driving area. At the same time, passengers standing in the area are marked and displayed to remind the driver to avoid pinching accidents caused by opening the door. The system detects blind spots and obstacles for passengers boarding and alighting, and reminds passengers to avoid traffic accidents when boarding and alighting.

[0041] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0042] This application provides a city bus boarding and alighting safety assistance system. Figure 1 , specifically including:

[0043] A sensor module configured to collect video image information inside and outside the vehicle;

[0044] CAN data transmission module, configured to transmit vehicle data information;

[0045] An on-board terminal module is configured to process and store the video image information and data information, and simultaneously obtain vehicle position information, and is connected to the sensor module and the CAN data transmission module respectively;

[0046] The human-computer interaction module is configured to display the data information, which includes in-vehicle passenger capacity information, vehicle operation information, external environment information and alarm information, and is connected to the vehicle-mounted terminal module.

[0047] Specifically, the sensor module, CAN data transmission module and the human-computer interaction module are all connected to the vehicle-mounted terminal module through an interface. The sensor module is used to collect video image information inside and outside the vehicle, and transmit it to the vehicle-mounted terminal module through the interface for processing and analysis. The CAN data transmission unit collects information such as vehicle speed and vehicle braking status, and transmits it to the vehicle-mounted terminal module. The vehicle-mounted terminal module judges the vehicle status based on the vehicle information and starts the corresponding processing function. For example, after the vehicle-mounted terminal module determines that the vehicle has stopped, it starts the vehicle-mounted terminal image recognition processing function. The human-computer interaction module is used to display the data information processed and analyzed by the vehicle-mounted terminal module through various terminal devices, so that passengers can obtain various information and make corresponding judgments in a timely manner, thereby avoiding congestion and traffic accidents.

[0048] In some embodiments, the system further includes a remote cloud platform configured to receive and / or transmit the vehicle location information, the vehicle operation information, and the vehicle passenger capacity information, and is communicatively connected to the vehicle-mounted terminal module. The system of this embodiment also includes a remote cloud platform. After receiving the vehicle-related information from the vehicle-mounted terminal module, the remote cloud platform transmits the vehicle-related information to other vehicle-mounted terminal modules, thereby enabling information exchange between vehicles and facilitating passengers' access to relevant information about different vehicles.

[0049] In some embodiments, the sensor module includes: a front camera, a rear camera, a right exterior camera, a front door camera, and a rear door camera. Specifically, the front camera is located at the front of the vehicle's exterior, the rear camera is located at the rear of the vehicle's exterior, the right exterior camera is located at the right of the vehicle's exterior, the front door camera is located at the front of the vehicle's interior, and the rear door camera is located at the rear of the vehicle's interior. That is, at least three cameras are located on the vehicle's exterior and at least two cameras are located on the vehicle's interior to capture video image information from both the interior and exterior of the vehicle.

[0050] In some embodiments, the vehicle-mounted terminal module includes: an interconnection communication unit, configured to communicate with the remote cloud platform; a central processing unit, configured to process the video image information and the data information; a storage unit, configured to store the video image information and the data information; a positioning unit, configured to obtain the vehicle location information; an interface unit, configured to connect with the sensor module, the CAN data transmission module and the human-computer interaction module; and a cache unit, configured to temporarily store the video image information and the data information.

[0051] The vehicle terminal module includes a central processing unit (CPU), as well as an interconnection and communication unit, a storage unit, a positioning unit, an interface unit, and a cache unit connected to the CPU. The CPU is responsible for analyzing, identifying, and processing video image information, as well as performing data fusion. It serves as the primary computational and control unit. The interconnection and communication unit is used to establish a wireless communication connection with the remote cloud platform, enabling information transmission with the remote cloud platform. It can transmit received data to the CPU or send information processed by the CPU to other modules. The storage unit is used to store video, data, and other information received or processed by the CPU. The positioning unit is used to obtain the vehicle's location information. The interface unit is responsible for communicating with the other modules.

[0052] In some embodiments, the human-computer interaction module includes: a first display screen, a second display screen, a first speaker, and a second speaker. The first display screen is located at the front of the vehicle exterior and is used to provide passengers waiting for boarding with information about the vehicle's interior and the vehicles preceding and following it. The second display screen is located at the rear door of the vehicle interior and is used to alert passengers to dangerous vehicles outside the vehicle, as well as provide guidance, advertising, and other information. The first speaker is located at the front door of the vehicle interior, and the second speaker is located at the rear door of the vehicle interior and is used to play prompts and warnings to passengers.

[0053] In some embodiments, after the vehicle stops, the on-board terminal module is specifically configured to fuse the video image information collected by the vehicle's front camera, the vehicle's rear camera, and the vehicle's external right camera, and display it through the human-computer interaction module.

[0054] Specifically, after the vehicle stops, the onboard terminal's image recognition and processing function is activated. The central processing unit, based on an algorithm, stitches and fuses images from the vehicle's front, rear, and right cameras to create a three-dimensional fused video. The second display then switches to displaying the real-time fused video, alerting passengers to dangerous vehicles outside the vehicle. The fused video is a 3D or 2D image stitched together from the three directional videos.

[0055] In some embodiments, after the vehicle stops, the on-board terminal module is specifically configured to process the video image information collected by the right-side camera outside the vehicle to identify the target dangerous vehicle; determine the position and speed information of the target dangerous vehicle based on the target dangerous vehicle and radar detection information; obtain the estimated collision time between the target dangerous vehicle and the getting-off passengers through calculation based on the position and speed information; generate alarm information based on the estimated collision time, and display the alarm information through the human-computer interaction module.

[0056] In this embodiment, a method for locating dangerous vehicles outside the bus when the bus is parked is disclosed. Figure 2 , including the following steps:

[0057] Step S101: Processing the video image information collected by the right side camera outside the vehicle to identify a target dangerous vehicle;

[0058] Step S102: determining the position and speed information of the target dangerous vehicle based on the target dangerous vehicle and radar detection information;

[0059] Step S103: deriving an estimated collision time between the target dangerous vehicle and the disembarking passenger by calculation based on the position and speed information;

[0060] Step S104: generating warning information based on the estimated collision time.

[0061] Specifically, the central processing unit processes the image information collected by the camera on the right side of the vehicle according to the algorithm, and identifies dangerous targets such as dynamic motorcycles, electric vehicles, bicycles, etc. on the right side of the vehicle. At the same time, the radar detection information on the right side of the vehicle is integrated to locate the dangerous target. The video image information collected by the camera on the right side of the vehicle is integrated with the radar information on the right side, which should be understood as the fusion of the position and speed information of the image-recognized target and the radar-detected target. The distance and speed of the dangerous target from the vehicle door are calculated to obtain the estimated collision time between the dangerous target and the passenger getting off the vehicle. According to the length of the estimated collision time, a graded alarm is issued through the first speaker to remind the passengers to pay attention, and the danger level of the target dangerous vehicle is marked on the second display screen.

[0062] In some embodiments, after the vehicle door is opened, the vehicle-mounted terminal module is specifically configured to obtain the in-vehicle passenger capacity information by calculation based on the video image information obtained by the sensor module.

[0063] In some embodiments, the passenger capacity information in the vehicle is obtained by calculation based on the video image information obtained by the sensor module, including: obtaining the personal physical value of each passenger getting on / off the vehicle by calculation based on the video image information obtained by the sensor module; obtaining the current effective area when each passenger is standing by calculation based on the personal physical value and the passenger spacing space; obtaining the current passenger capacity value in the vehicle based on the number of people getting on the vehicle, the number of people getting off the vehicle, and the current effective area when each passenger is standing; obtaining the current number of people that can be accommodated in the vehicle by calculation based on the current passenger capacity value in the vehicle and the number of passengers already in the vehicle.

[0064] In this embodiment, a method for calculating the current number of passengers in a vehicle is disclosed. Figure 3 , including the following steps:

[0065] Step S201: Obtaining the individual physical value of each passenger getting on / off the bus by calculation based on the video image information acquired by the sensor module;

[0066] Step S202: Calculate the current effective area for each passenger when standing based on the individual's physique value and the passenger spacing;

[0067] Step S203: Calculate the current passenger capacity value in the vehicle based on the number of passengers getting on the vehicle, the number of passengers getting off the vehicle, and the current effective area when each passenger is standing;

[0068] Step S204: Calculate the number of passengers that can currently be taken in the vehicle based on the current passenger capacity limit in the vehicle and the number of passengers already in the vehicle.

[0069] Specifically, the vehicle terminal receives door switch signals via the CAN data transmission unit. Upon detecting the door opening signal, the central processing unit activates its image recognition function, analyzes and processes images from the vehicle's front and rear door cameras, and determines the number of passengers boarding and alighting. An algorithm is then used to calculate the vehicle's current passenger capacity and occupancy limit, which are displayed in real time on the first display screen, providing passengers waiting to board with interior space information.

[0070] The vehicle content limit is calculated as follows:

[0071]

[0072] Where N is the number of passengers in the vehicle, P S is the number of designed passenger seats, S1 is the effective area for standing passengers in the car; S SP The effective area occupied by each standing passenger. SP = S2 + S3, where S2 is the individual's physique and S3 is the standing space between people. The individual's physique includes the space occupied by the body and backpack, and is calculated based on the maximum space occupied in the vehicle.

[0073] Usually S SP Calculation based on a certain specified value may differ from the actual effective area occupied by each standing passenger. Therefore, this application provides a new method for calculating the vehicle content limit and the number of passengers that can be taken in a vehicle by obtaining the effective standing area of ​​each passenger getting on and off the vehicle in real time.

[0074] The method uses the vehicle terminal to analyze the real-time video image information of passengers getting on and off the vehicle collected by the vehicle front door camera and the vehicle rear door camera. When a passenger gets on / off the vehicle, the current personal physique value S2′ of each passenger is calculated. At the same time, the current effective area S occupied by each passenger when standing in real time can be calculated. SP ′=S2′+S3. Taking into account the randomness of the number of passengers and standing people in the car, the average physical size of all passengers in the car is used to estimate the current effective area occupied by each passenger when standing in the car. When a passenger gets on the car, the available space is occupied. When a passenger gets off the car, the available space is released. Based on the increase or decrease in the number of passengers in the car, the average effective area S occupied by each passenger in the car when standing in real time is obtained. SP ″

[0075]

[0076] Among them, S SP' is the current effective area occupied by each passenger standing in real time, n represents the number of passengers getting on the bus, m represents the number of passengers getting off the bus, 0≤i≤n, 0≤j≤m. Therefore, the current passenger capacity value in the bus is obtained

[0077]

[0078] The current number of people that can be taken in the car is

[0079] N1=N′-N2 (4) where N2 is the number of passengers already in the vehicle. This calculation method can provide passengers waiting to board the vehicle with information about the actual space inside the vehicle, preventing passengers from rushing onto the vehicle, causing overcrowding and preventing the driver from being able to close the door.

[0080] When the vehicle arrives at a station and passengers are boarding / disembarking, the actual number of passengers in the vehicle is calculated in real time and provided to passengers waiting to board outside the vehicle. When the number of passengers in the vehicle reaches 0, the first and second speakers in the vehicle are activated to remind passengers waiting to board that the vehicle is crowded, so as to reduce the difficulty of the driver in closing the door or accidents of passengers being pinched due to excessive crowding.

[0081] The remote cloud platform receives the location information and passenger capacity information from the onboard terminals of all vehicles operating along the entire route. It then transmits the position information and passenger capacity information of the subsequent vehicle relative to the previous vehicle to the onboard terminal of the previous vehicle, which is then displayed on the first display screen of the vehicle. The subsequent vehicle should be understood as the vehicle that arrives at the station first after the previous vehicle on the same route. The content displayed on the first display screen includes, but is not limited to, the vehicle's capacity limit and passenger capacity, as well as the distance to the station, arrival time, vehicle capacity limit, and passenger capacity of the next vehicle.

[0082] In some embodiments, the human-computer interaction module also includes a driving area display device, and the vehicle-mounted terminal module is specifically configured to mark the video image information collected by the vehicle front door camera and the vehicle rear door camera to obtain passenger marking information of the prohibited standing area, and send the passenger marking information to the driving area display device. Therefore, the present application can provide the passengers waiting to get on the bus with information about the vehicle and the next vehicle, and provide a reference for passengers to get on the bus. Avoid peak passenger flow, passengers blindly crowding onto the bus, forcing their way onto the bus, causing excessive crowding in the bus, making it impossible to close the door, or causing traffic accidents such as being pinched by the door.

[0083] Using video feeds from the vehicle's front and rear door cameras, the onboard terminal module monitors areas where passengers could be easily pinched when opening and closing doors, and displays this information on the driver's display. If a passenger is detected standing in this area, an algorithm identifies them and displays the information on the driver's display. Simultaneously, an alarm alerts the driver to avoid opening and closing doors.
