Description

Technical Field

[0001] The present invention relates to the technical field of urban rail transit, and in particular to an electronic explanation system and method for urban rail trains. Background Art

[0002] Urban rail transit, as a key component of the modern urban transportation system, plays an important role in connecting all corners of the city and promoting the flow of people and economic development. It is usually composed of multiple modes of transportation such as subways, light rails, and trams, and is characterized by its high efficiency, speed, and environmental protection.

[0003] In the field of urban rail transit, the equipment that provides information to passengers in the past is basically fixed inside the carriage, such as the traditional in-car broadcasting system and fixed display boards. These devices allow passengers to passively listen to the broadcast content or watch the limited information on the display board, without the right to choose independently. Moreover, the broadcast content is uniformly set and played in a loop, and cannot be adjusted according to the interests and needs of different passengers. In addition, the information provided by these fixed devices is difficult to update, and information such as changes in facilities around stations and temporary adjustments to train operations is difficult to convey to passengers in a timely manner. At the same time, since the fixed equipment of different models is relatively independent, it is difficult for passengers to quickly adapt and obtain accurate information when transferring to different trains. With the popularization of smart phones and the continuous improvement of people's requirements for travel experience, this passive and single way of obtaining information can no longer meet the diverse needs of passengers.

[0043] The present invention provides an urban rail train electronic explanation system, comprising an on-board Bluetooth device 101, an NFC device 102, a mobile phone APP 103, a cloud server 104 and an intelligent information host 105, wherein the on-board Bluetooth device 101 and the NFC device 102 are both connected to the mobile phone APP 103, and the mobile phone APP 103 is also connected to the cloud server 104 and the intelligent information host 105;

[0044] The intelligent information host 105 is used to collect location information in real time, and based on rule judgment, trigger instructions, and push the explanation instructions to the mobile phone APP via the wireless network;

[0045] The vehicle-mounted Bluetooth device 101 is installed in each compartment of the urban rail train and is used for Bluetooth connection and data transmission tasks with the mobile phone APP 103;

[0046] The NFC device 102 is installed in a conspicuous position in the train compartment and is used to store information related to the train.

[0047] For this specific implementation, when it is used, passengers need to download and install a special urban rail train electronic explanation APP on their smart phones, that is, the mobile phone APP 103 of the present invention. The mobile phone APP 103 integrates multiple functional modules to provide passengers with convenient and comprehensive information services. When passengers take the urban rail train, they can turn on the Bluetooth function of the mobile phone and start the mobile phone APP 103. The mobile phone APP 103 automatically searches for the surrounding vehicle-mounted Bluetooth devices 101. When the signal of the vehicle-mounted Bluetooth device 101 on the train is detected, the passenger clicks the connection button to connect; or the passenger can directly touch the mobile phone to the NFC device 102 installed in the car;

[0048] If connected via Bluetooth, after the connection is successful, the vehicle-mounted Bluetooth device 101 sends real-time train information (such as current train location, upcoming stations, station transfer information, etc.) and pre-stored related knowledge (such as tourist attractions and commercial facilities around the station, etc.) to the passenger's mobile phone;

[0049] If the information is obtained by NFC touch, the mobile phone APP 103 reads the information identifier of the NFC device 102 and obtains the corresponding train information from the cloud server 104 or the associated vehicle-mounted Bluetooth device 101 data. After receiving these data, the mobile phone APP 103 converts the data into a displayable format through its internal parsing module. On the interface of the mobile phone APP 103, the train information is displayed in the form of pictures and texts, which solves the technical problem that the information transmission method of urban rail transit in the existing technology is difficult to meet the passengers' initiative, personalization and real-time needs for information acquisition due to the limitation of fixed equipment.

[0050] The in-vehicle Bluetooth device 101 includes a Bluetooth communication module 106, a central processing unit 107, a storage module 108 and a power management module 109.

It can quickly process data from the train control system or cloud server 104, and send relevant information to the Bluetooth communication module 106 according to instructions;

[0056] The power management module 109 is responsible for providing a stable power supply to each component of the vehicle-mounted Bluetooth device 101, and also has a power optimization management function to reduce the power consumption of the device and ensure stable operation during the train operation.

[0057] Secondly, the NFC device 102 includes an antenna 111, a storage unit 112, an NFC chip 113 and a power management circuit 114, the antenna 111 is connected to the mobile phone APP 103, and the storage unit 112, the antenna 111 and the NFC chip 113 are all connected to the power management circuit 114;

[0058] The NFC chip 113 is used to process operations related to the NFC communication protocol to achieve near field communication function with the mobile phone;

[0059] The antenna 111 is used to transmit and receive NFC signals to ensure stable communication with a mobile phone that supports the NFC function; the design of the antenna 111 is optimized to have good signal coverage and anti-interference capabilities, and can ensure reliable transmission of information even in the complex electromagnetic environment in the vehicle.

[0060] The storage unit 112 is used to store information identification related to the train;

[0061] The power management circuit 114 provides a stable power supply for each component of the NFC device. The low-power design can effectively reduce the energy consumption of the device and extend the service life of the device. In addition, the power management circuit 114 also has overvoltage and overcurrent protection functions to ensure that the device can operate safely and stably in various complex power supply environments.

[0062] In this specific implementation, the NFC devices are installed in multiple conspicuous locations in the train compartment, such as near the door, next to the seat armrest, etc. The NFC devices 102 store information tags related to the train. They adopt a low-power design to ensure stable operation during the long-term operation of the train, and have high security to prevent information from being illegally read or tampered with;

[0063] The NFC chip 113 is a core component responsible for processing operations related to the NFC communication protocol and realizing the near field communication function with the mobile phone. It can quickly and accurately read and write information identification, and encrypt and decrypt data to ensure the security of information transmission. The chip has the characteristics of high integration and can effectively reduce the power consumption and volume of the device.

[0064] At the same time, the mobile phone APP 103 includes a connection function module 115, a data processing module 116, an information display module 117, a network communication module 118 and a data storage layer 119.

[0065] The mobile phone APP 103 also includes a voice service module 120 , and the voice service module 120 is also connected to the data processing module 116 .

[0066] For this specific implementation, the connection function module 115 includes two parts: Bluetooth connection and NFC function. The Bluetooth connection part can automatically search for the surrounding vehicle-mounted Bluetooth devices 101. Once the train Bluetooth signal is detected, the passenger can easily connect by clicking to achieve data interaction with the vehicle-mounted Bluetooth device 101. The NFC function part allows the mobile phone to touch the NFC device 102 in the car and use the NFC near-field communication technology to read the information identification in the device, thereby obtaining relevant train information.

[0067] The data processing module 116 is responsible for receiving data from the vehicle-mounted Bluetooth device 101, the cloud server 104 or the NFC device, and parsing data in different formats. For example, the train information in JSON format is converted into structured data that can be recognized and processed by the APP, which is convenient for subsequent display and use. In addition, the module also has data storage and cache management functions, using the SQLite lightweight database to store commonly used data and user personalized settings locally, such as the station information recently browsed by passengers, voice playback settings, etc., so that when the network is not good, it can also provide passengers with certain information services, while reducing repeated data acquisition and improving the response speed of the APP.

[0068] The information display module 117 is designed with a user-friendly interface to intuitively display the parsed data. The train location and station distribution are clearly presented in the form of a map, and the station information and surrounding introduction are listed in detail in the form of a list, etc., fully focusing on the aesthetics and interactivity of the interface, which greatly facilitates passenger operation.

[0069] The network communication module 118 communicates with the cloud server 104 based on the HTTP / 2 protocol, and can obtain the latest data updates in a timely manner, such as real-time adjustment information of train operation and new content around the station.

[0070] The voice service module 120 provides voice explanation services for passengers. The module supports multiple voice styles and speech speed adjustment to meet the auditory needs of different passengers. It also has functions such as voice pause, resume and fast forward, which facilitates passengers to independently control the voice playback process.

[0071] When using the electronic explanation system for urban rail trains of this embodiment, passengers need to download and install a special electronic explanation APP for urban rail trains on their smart phones, that is, the mobile phone APP 103 of the present invention. The mobile phone APP 103 integrates multiple functional modules to provide passengers with convenient and comprehensive information services. When passengers take the urban rail train, they can turn on the Bluetooth function of their mobile phone and start the mobile phone APP 103. The mobile phone APP 103 automatically searches for the vehicle-mounted Bluetooth device 101 around them. When the signal of the vehicle-mounted Bluetooth device 101 on the train is detected, the passenger clicks the connection button to connect; or they can directly touch the mobile phone to the NFC device 102 installed in the car;

[0072] If connected via Bluetooth, after the connection is successful, the vehicle-mounted Bluetooth device 101 sends real-time train information (such as current train location, upcoming stations, station transfer information, etc.) and pre-stored related knowledge (such as tourist attractions and commercial facilities around the station, etc.) to the passenger's mobile phone;

[0073] If the information is obtained by NFC touch, the mobile phone APP 103 reads the information identifier of the NFC device 102 and obtains the corresponding train information from the cloud server 104 or the associated vehicle-mounted Bluetooth device 101 data. After receiving these data, the mobile phone APP 103 converts the data into a displayable format through its internal parsing module.
