Description

Technical Field

[0001] This utility model belongs to the technical field of traffic management facilities and relates to a management device for time-limited relocation of bus stops. Background Technology

[0002] In the current state of urban public transportation development, the contradiction between high-density bus routes and limited station capacity is becoming increasingly prominent. The resulting "bus train phenomenon" has become a major constraint on the level of public transportation services and the disruption of road traffic operations. Especially on main urban roads near business districts and schools, the congestion caused by "bus train" during peak hours is becoming increasingly severe. A large number of buses queue to enter the station and occupy road resources for a long time. Coupled with complex road conditions, this not only reduces traffic efficiency but also increases the risk of accidents.

[0003] Previous measures such as expanding station capacity, optimizing routes, and prioritizing public transport have proven inadequate when faced with the rigid demand of highly overlapping bus routes and roads operating at high saturation. To address this intractable situation, it is necessary to explore precise governance measures that combine "time-limited relocation with dynamic optimization."

[0004] By temporarily relocating some bus routes to diversion points during peak hours, the problem of "bus train-like" traffic congestion can be significantly alleviated, road traffic order can be improved, and bus stop delays can be reduced. However, there are currently gaps in the related guidance and management facilities, leading to a lack of information sharing among buses, drivers, and passengers. This poses a risk of disconnect under dynamic management, affecting the effectiveness of the measures. To expedite the implementation of this technology and effectively alleviate urban traffic congestion, there is an urgent need to develop a traffic management facility suitable for "time-limited relocation of bus stops." Utility Model Content

[0005] The purpose of this utility model is to provide a management device for the time-limited relocation of bus stops, adding temporary stops and setting up corresponding guidance signs to alleviate urban traffic congestion.

[0006] To achieve the above objectives, the basic solution of this utility model is: a management device for time-limited relocation of bus stops, including an original LED variable sign module, a temporary LED variable sign module, and a control module;

[0007] The original LED variable sign module is installed at the original site, and the temporary LED variable sign module is set at the location of the temporary site.

[0008] The control module includes a microcontroller and a NOT gate. The microcontroller pre-stores peak periods. The output of the timer in the microcontroller is connected to the peak display start-up terminal of the original LED variable sign module and the peak display start-up terminal of the temporary LED variable sign module. The output of the timer is connected to the off-peak display start-up terminal of the original LED variable sign module and the off-peak display start-up terminal of the temporary LED variable sign module after passing through the NOT gate.

[0009] The original LED variable sign module contains a map of all vehicle stops that is preset to be displayed during off-peak hours, and a map of the location of temporary stops and pedestrian flow that is preset to be displayed during peak hours.

[0010] The temporary LED variable sign module stores a preset LED image of temporary stations being turned off during off-peak hours and a preset image of the corresponding original stations and vehicle route information during peak hours.

[0011] The working principle and beneficial effects of this basic solution are as follows: This technical solution is based on a control module, which pre-stores peak periods in the microcontroller. Based on a timer, it outputs control signals to the corresponding start terminals of the original LED variable sign module and the temporary LED variable sign module, so that the original LED variable sign module and the temporary LED variable sign module display the corresponding sign information during off-peak and peak hours, thereby guiding passengers to board the bus at the original station or to the temporary station, thus alleviating urban traffic congestion.

[0012] Furthermore, the control module also includes RFID electronic tags, RFID readers, and vehicle-mounted terminals;

[0013] The RFID electronic tag is installed upstream of the temporary site, and the activation end of the RFID electronic tag is linked to the peak display activation end of the temporary LED variable sign module.

[0014] The RFID reader and vehicle-mounted terminal are installed on the bus. The input end of the RFID reader can be connected to the RFID electronic tag, and the output end of the RFID reader is connected to the input end of the vehicle-mounted terminal. The vehicle-mounted terminal issues a prompt message indicating that the bus will enter a temporary station during peak hours.

[0015] RFID tags are installed upstream of temporary bus stops. During peak hours, these tags and temporary LED variable sign modules activate synchronously. The RFID tags then send signals to RFID readers on nearby buses. These readers output signals to the onboard terminal, which then issues a peak-hour notification to the bus driver, allowing them to proceed to the temporary stop. This also informs passengers on board. This system enables information sharing between the bus stop and the bus, as well as communication between the bus, driver, and passengers, optimizing the dynamic traffic flow.

[0016] Furthermore, the control module also includes a traffic flow sensor and a traffic flow comparator;

[0017] The traffic flow sensor is installed at the original station to collect traffic flow data at the original station.

[0018] The first input terminal of the traffic flow comparator is connected to the output terminal of the traffic flow sensor, the second input terminal of the traffic flow comparator is connected to the traffic flow threshold memory, and the output terminal of the traffic flow comparator is simultaneously connected to the peak display start terminal of the original LED variable sign module and the peak display start terminal of the temporary LED variable sign module.

[0019] Traffic flow sensors are installed to collect traffic flow data at the original station location and transmit it to a traffic flow comparator. This allows for dynamic determination of the start and end of peak periods, thus optimizing the pipeline at temporary stations.

[0020] The traffic flow comparator compares the collected traffic flow data with the threshold value stored in the traffic flow threshold memory. If the collected traffic flow data is greater than or equal to the threshold value stored in the traffic flow threshold memory, it indicates that the original station is experiencing peak traffic and a temporary station needs to be activated. At this time, the traffic flow comparator outputs a control signal to the peak display activation terminals of both the original and temporary LED variable sign modules, activating them and displaying the corresponding signs to inform passengers that they can be diverted to the temporary station.

[0021] Furthermore, the control module also includes a human-machine interaction module, which is connected to the threshold modification terminal of the traffic flow threshold memory.

[0022] Staff can adjust the threshold size in the traffic flow threshold memory based on historical traffic flow data and as needed through the human-computer interaction module, making it more flexible to use.

[0023] Furthermore, the control module also includes a positioning module, which is installed on the bus. The output of the positioning module is connected to the original LED variable sign module and the temporary LED variable sign module via a wireless transmission module.

[0024] A positioning module is installed on the bus to obtain the bus's location information. The positioning module transmits the bus's location information to the original LED variable sign module and the temporary LED variable sign module via a wireless transmission module for display, making it convenient for passengers to view.

[0025] Furthermore, it also includes a power module, which is connected to the charging terminals of the original LED variable sign module, the temporary LED variable sign module, and the control module, respectively.

[0026] The power supply module is configured to supply power to the original LED variable sign module, the temporary LED variable sign module, and the control module to ensure smooth operation of the equipment. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0035] This utility model discloses a management device for time-limited relocation of bus stops, such as... Figure 1As shown, it includes the original LED variable sign module 2 (such as...) Figure 4 As shown), a temporary LED variable sign module and a control module are provided. The control module can be installed (e.g., integrated installation, adhesive bonding, welding, riveting, snap-fitting, etc.) in the main control room of the bus.

[0036] The original LED variable sign module 2 is installed at the original site 1, and the temporary LED variable sign module is set at the location of the temporary site. Both the original LED variable sign module 2 and the temporary LED variable sign module can be intelligent displays or similar devices, and can be installed on the ground at the corresponding site using brackets.

[0037] The control module includes a microcontroller and NOT gates. The microcontroller has pre-stored peak periods (such as weekly or daily). The microcontroller can be an STM32 or a real clock, such as a DS3231.

[0038] For example, using an STM32F103C8T6 microcontroller, a 74LS04 NOT gate, and transistors (e.g., 2N2222), the microcontroller and timer are integrated. The output of the timer in the microcontroller is electrically connected to the peak display start-up terminal of the original LED variable sign module 2 and the peak display start-up terminal of the temporary LED variable sign module. The output of the timer is electrically connected to the off-peak display start-up terminal of the original LED variable sign module 2 and the off-peak display start-up terminal of the temporary LED variable sign module after passing through the NOT gate.

[0039] The original LED variable sign module 2 contains a preset display of all vehicle stopping routes during off-peak hours, and a preset display of the location of temporary stations and pedestrian flow direction during peak hours.

[0040] The temporary LED variable sign module stores a preset image of the temporary station LEDs being turned off during off-peak hours, and a preset image of the original station 1 and vehicle route information during peak hours.

[0041] The specific pin connections are as follows: The output signal of the timer output pin TIM1 (PA8) of the STM32F103C8T6 microcontroller serves as the trigger signal. One path is connected to the base of the first transistor, and the collector of the first transistor is electrically connected to the peak display start-up terminal of the original LED variable sign module 2 and the peak display start-up terminal of the temporary LED variable sign module. The other path is connected to the input of an NOT gate. After receiving the timer signal, the NOT gate outputs an inverted signal to the base of the second transistor, which is controlled to turn on and off by a resistor (e.g., 1kΩ). The collector of the second transistor is electrically connected to the off-peak display start-up terminal of the original LED variable sign module 2 and the off-peak display start-up terminal of the temporary LED variable sign module. The positive terminal of the LED module is connected to a 5V power supply, and the emitter of the transistor is grounded (GND).

[0042] The specific structure and operation of the variable flag module can be achieved using existing technologies, and this patent application does not improve upon them, so they will not be described in detail here.

[0043] Peak periods are pre-stored in the microcontroller. Based on the timer, the control signal is output to the corresponding start terminals of the original LED variable sign module 2 and the temporary LED variable sign module, so that the original LED variable sign module 2 and the temporary LED variable sign module display the corresponding sign information during off-peak and peak hours, thereby guiding passengers to board the bus at the original station 1 or to the temporary station, thus alleviating urban traffic congestion.

[0044] In a preferred embodiment of this utility model, such as Figure 2 As shown, the control module also includes RFID electronic tags (such as Alien ALN-9640, Impinj R6-A, Siemens RF600, etc.), RFID readers (such as Zebra FX9600, Impinj Speedway R420, ThingMagic M6e, etc.), and vehicle-mounted terminals (such as Advantech TPC-315W, Siemens SIMATIC HMI, etc.). The RFID electronic tags (i.e., RFID tags) are installed upstream of the temporary station, and the activation end of the RFID electronic tag is linked to the peak display activation end of the temporary LED variable sign module.

[0045] For example, the Impinj R6-A active electronic tag can be installed 50-100m upstream of a temporary site. Specifically, the AlienALN-9640 tag can be installed at a 45° angle on a streetlight pole (2.5m high), with the tag ID bound to the site's GIS coordinates. The ZebraFX9600 reader is electrically connected to the vehicle terminal via a CAN bus. The RFID reader can be embedded in the front bumper of the vehicle, with the antenna facing the road surface (15° downward angle).

[0046] RFID readers and vehicle-mounted terminals are installed on buses (e.g., by welding, bonding, riveting, etc.). The input end of the RFID reader can be electrically connected to the RFID electronic tag, and the output end of the RFID reader can be electrically connected to the input end of the vehicle-mounted terminal. The vehicle-mounted terminal issues a notification message indicating that the bus will enter a temporary stop during peak hours. The vehicle-mounted terminal can be equipped with modules such as a buzzer, audio system, loudspeaker, and LED display for information display.

[0047] RFID tags are installed upstream of temporary bus stops. During peak hours, these tags and temporary LED variable sign modules activate synchronously. The RFID tags then send signals to RFID readers on nearby buses. These readers output signals to the onboard terminal, which then issues a peak-hour notification to the bus driver, allowing them to proceed to the temporary stop. This also informs passengers on board. This system enables information sharing between the bus stop and the bus, as well as communication between the bus, driver, and passengers, optimizing the dynamic traffic flow.

[0048] In a preferred embodiment of this utility model, the control module further includes a traffic flow sensor (such as a digital signal output type: TE Connectivity LX3302 geomagnetic sensor; Sick UM30-213115 lidar; FLIR TrafiCam AI video detection camera, etc.; or an analog signal output type: Kistler 9192A).

[0049] Piezoelectric sensors; Banner QS18VN6LV microwave radar; Inductive Loop 2400 loop coil, etc.) and traffic flow comparators (such as embedded dedicated comparators: Texas Instruments TLV3201 voltage comparator; STMicroelectronics STM32H743 ARM Cortex-M7 multi-dimensional algorithm comparison, etc.; edge computing comparators: NVIDIA Jetson Xavier NX supporting TensorRT; Advantech UNO-2483G supporting Python / C++, etc.).

[0050] The traffic flow sensor is installed (e.g., embedded, welded, bonded) at the original station 1 to collect traffic flow data. The comparator in this invention can be based on the corresponding sensor it connects to, employing either a digital or analog comparator. Furthermore, a digital-to-analog converter or an analog-to-digital converter can be connected to the input of the comparator as needed.

[0051] The first input terminal of the traffic flow comparator is electrically connected to the output terminal of the traffic flow sensor. The second input terminal of the traffic flow comparator is electrically connected to a traffic flow threshold memory (such as AT24C1024B; W25Q128JV, etc.). The output terminal of the traffic flow comparator is electrically connected to both the peak display start terminal of the original LED variable sign module 2 and the peak display start terminal of the temporary LED variable sign module.

[0052] For example, the TE Connectivity LX3302 geomagnetic sensor outputs a vehicle-passing pulse signal. The STM32H743 comparator calculates the number of pulses per unit time in real time and compares it to a threshold. When the flow exceeds the threshold, a migration trigger signal is sent via the CAN bus to the corresponding start terminal of the corresponding flag module.

[0053] Traffic flow sensors are installed to collect traffic flow data at the original station 1 location and transmit it to the traffic flow comparator. This allows for dynamic determination of the start and end of peak periods, thus optimizing the temporary station pipeline.

[0054] The traffic flow comparator compares the collected traffic flow data with the threshold value stored in the traffic flow threshold memory. If the collected traffic flow data is greater than or equal to the threshold value stored in the traffic flow threshold memory, it indicates that the original station 1 is experiencing peak traffic and a temporary station needs to be activated. At this time, the traffic flow comparator outputs a control signal to the peak display activation terminals of the original LED variable sign module 2 and the temporary LED variable sign module, activating both modules and displaying the corresponding signs to inform passengers that they can be diverted to the temporary station.

[0055] In a preferred embodiment of this utility model, the control module further includes a human-machine interaction module (such as an industrial touch screen: Siemens KTP700 Basic, Weintek MT8071 iE, etc.; physical control panel: EAO 84 series buttons, Bourns PEC11 R encoder, etc.), and the human-machine interaction module is electrically connected to the threshold modification terminal of the traffic flow threshold memory.

[0056] For example, a Weintek MT8071 iE industrial touchscreen is installed, integrating a 4G communication module; the industrial touchscreen interacts with the threshold memory via the Modbus RTU protocol.

[0057] Staff can adjust the threshold size in the traffic flow threshold memory based on historical traffic flow data and as needed through the human-computer interaction module, making it more flexible to use.

[0058] In a preferred embodiment of this utility model, such as Figure 3As shown, the control module also includes a positioning module, which is installed on the bus. The output of the positioning module (i.e., the vehicle-mounted positioning module, which can use 5G C-V2X PC5 direct communication; such as existing GPS positioning modules, Beidou positioning systems, etc., such as u-blox ZED-F9P, Septentrio AsteRx-i, Quectel LG69T, etc.) transmits data to the roadside communication gateway (which can be based on IEEE 802.11p communication) through the wireless transmission module. Then, the roadside communication gateway is electrically connected to the original LED variable sign module 2 (original stop 1 LED sign) and the temporary LED variable sign module (temporary stop LED sign).

[0059] For example, the vehicle-mounted u-blox ZED-F9P positioning module outputs centimeter-level location data in real time. This data is then transmitted to the roadside communication gateway via the Quectel AG550Q wireless module using the 5G NR-V2X protocol. The roadside communication gateway controls the LED variable sign content at both the original and temporary stations via an RS-485 bus.

[0060] A positioning module is installed on the bus to obtain the bus's location information. The positioning module transmits the bus's location information wirelessly to the original LED variable sign module 2 and the temporary LED variable sign module for display, making it convenient for passengers to view.

[0061] In a preferred embodiment of this utility model, the management equipment for time-limited relocation of bus stops further includes a power module. The power module is electrically connected to the charging terminals of the original LED variable sign module 2, the temporary LED variable sign module, and the control module. The power module can be powered by external AC power or a battery module.

[0062] The power supply module is configured to supply power to the original LED variable sign module 2, the temporary LED variable sign module, and the control module, ensuring smooth operation of the equipment.
