Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of intelligent transportation, specifically relating to an intelligent public transportation service device and system. Background Technology
[0002] Traditional bus stop signs typically use text to display static information about the bus routes passing through the stop. More advanced electronic bus stop signs, however, incorporate electronic displays that can show not only static route information but also dynamic information about buses on those routes via network connectivity. However, due to the high power consumption and the integration of numerous modules, the cost of building and maintaining electronic bus stop signs is often substantial, leading many cities to halt new projected signs.
[0003] Bus stops serve passengers of all ages, and electronic bus stop signs, in particular, require real-time information and functional adaptability throughout the entire day's operation. However, the core design logic of low-power devices inherently clashes with the core needs of this scenario, thus preventing their widespread adoption in mainstream electronic bus stop applications. Passenger flow at bus stops exhibits significant dynamic characteristics, with surges in query demands during morning and evening peak hours, while off-peak hours see intermittent queries. Devices must flexibly adjust their operating status according to passenger flow changes: during peak hours, they need to respond to queries frequently and quickly refresh real-time bus locations and arrival prediction data; during off-peak hours, they must maintain basic network connectivity and information update capabilities, making it impossible to remain in a low-power sleep mode for extended periods. Simultaneously, electronic bus stop signs need to access the bus dispatch and positioning systems in real-time to obtain dynamic data, and also support services such as information push notifications and temporary route adjustment announcements. Continuous network transmission and data processing generate stable power consumption, contradicting the design intent of low-power devices to "reduce activity frequency and lower transmission power consumption." Furthermore, electronic bus stop signs often need to integrate high-brightness displays, voice broadcasts, touch interactions, and other functional modules. In some scenarios, they also need to adapt to complex outdoor environments such as low and high temperatures. The operation of these functions requires a stable power supply. However, traditional low-power devices mostly rely on batteries or energy harvesting for power, which is difficult to meet the energy consumption requirements of electronic bus stop signs for high-frequency data interaction and multi-module collaborative work. Forcing them to adapt may lead to information update delays, sluggish interactive responses, or even service interruptions due to insufficient power supply, affecting the passenger travel experience.

[0037] This application discloses an intelligent public transportation service system, including: intelligent public transportation service equipment and a cloud service platform, wherein: The intelligent public transportation service equipment communicates with the cloud service platform to send query requests for target bus routes to the cloud service platform, and to receive and display real-time public transportation information service data from the cloud service platform. The cloud service platform is configured to acquire real-time bus operation data from at least one on-board terminal, and in response to query requests, generate real-time bus information service data based on the real-time bus operation data and distribute it to intelligent bus travel service equipment.
[0038] This application discloses a control method for an intelligent public transportation service device, which employs the intelligent public transportation service device disclosed in the above embodiments and includes the following steps: S1. In response to the user's first input operation, the trigger signal module 2 sends a trigger signal to the processor module 1, wherein the first input operation can be that the user presses the trigger signal module 2; S2. After receiving the trigger signal, the processor module 1 activates the power supply control module 4 to supply power to the mobile communication module 6 and / or the wireless Bluetooth module 8. S3, Processor module 1 sends a query request for the target bus route to the cloud service platform through mobile communication module 6; S4. The cloud service platform obtains real-time bus operation data from at least one vehicle terminal and responds to query requests. Based on the real-time bus operation data, it generates real-time bus information service data and distributes it to intelligent bus travel service equipment. S5. Processor module 1 receives real-time bus information service data from the cloud service platform, generates bus information broadcast data, and sends it to speaker 71; S6 and 71 broadcast real-time bus operation data to users based on bus information broadcast data; S7. In response to the user's second input operation, select the currently broadcast bus route. The second input operation can be that the user presses and holds the trigger signal module 2 according to the broadcast sound. S8, Processor module 1 sends a bus selection signal to the cloud service platform based on the selected bus route; S9. The cloud service platform sends a reservation request to the corresponding bus based on the selected bus signal. During the reservation request period, after the reserved bus enters the station, the bus sends a vehicle arrival signal to the wireless Bluetooth module 8 through the bus Bluetooth module. The processor module 1 activates the information prompt module 7 (buzzer 72 or horn 71) to remind the user to board the bus based on the vehicle arrival signal. S10. If the processor module 1 does not receive an operation signal from the trigger signal module 2 within a preset time, the processor module 1 enters a sleep state, and the power supply control module 4 stops supplying power to the mobile communication module 6. The preset time can be 15 seconds after the reservation ends (i.e., 15 seconds after the reservation ends and the user boards the bus). Within this 15-second time range, if no other user operates the trigger signal module 2, the processor module 1 enters a sleep state, which can effectively reduce the power consumption of the device and thus achieve energy saving. In the sleep state, the processor module 1 will continuously start the wireless Bluetooth module 8 based on the battery power information, such as when the battery power is above 30%. Users can wake up the processor module 1 through a mobile terminal (e.g., a mobile phone) to obtain real-time bus operation information, which will then be broadcast to the user. In another embodiment, the wireless Bluetooth module 8 can also be preset to be in a normally open state, without needing to select the off or on state of the wireless Bluetooth module 8 based on the battery power information, making it convenient for users who are inconvenient to press buttons to obtain real-time bus operation information.
[0039] The trigger signal module 2 includes buttons for regular people, visually impaired people, and wheelchair users. By pressing different buttons, query requests for regular people, visually impaired people, and wheelchair users can be sent respectively. Depending on the request, a reservation request for regular people, a reservation request for visually impaired people, and a reservation request for wheelchair users will be sent to the bus. The bus driver can make adaptive arrangements according to different requests.
[0040] This invention supports Bluetooth, button activation, and automatic timer wake-up. The terminal device installed on a bus needs to have a bus Bluetooth module. Bluetooth wake-up is used to establish a communication connection between the bus's Bluetooth module and the invention's wireless Bluetooth module 8 when the bus arrives at a stop, automatically announcing the stop. If the user has booked a bus, the invention will automatically announce the arrival and remind the user to board. Bluetooth wake-up also has a mobile terminal wake-up function; for example, it can automatically wake up when a user walks to the bus stop with their mobile phone, automatically announcing real-time bus information. Button wake-up comes in three types: one for the elderly and children, one with Braille, and one for wheelchairs. All three require a single press to announce real-time bus information; a long press allows booking the desired bus. All modules use existing low-power hardware. The battery can use 50Ah (ampere-hours), supporting one year of use. The reservation function addresses the issue of disabled people not knowing when the bus will arrive at a stop. Reservations also alert drivers to potential disabled passengers at the stop, prompting them to lower the step or provide assistance upon arrival. Furthermore, it's useful in cities where buses don't stop at every station; reservations inform drivers of upcoming boarding stops. Communication supports two methods: a low-power 4G / 5G module and a wireless Bluetooth module. The 4G / 5G module is used to retrieve real-time bus information from the cloud and transmit reservation information.
