Description

TECHNICAL FIELD

[0001] The present application relates to the field of wireless transmission, in particular to a near-field information transmission system and a use method thereof. BACKGROUND

[0002] Currently, the road traffic management system generally relies on the Traffic Management Control Center (TMCC), Virtual Private Network (VPN), Internet and various road side units (RSU) with electric control capabilities to form the overall operation architecture. The traffic management control center is usually connected with the front-end equipment through a dedicated communication link to collect road environment information, issue traffic prompts or realize signal control. However, in most actual road environments, there are still a large number of traditional roadside facilities without electric control capabilities, such as temporary warning signs, construction signs, traffic cones, and manually set road signboards, etc. These facilities cannot actively transmit information to surrounding road users, and traffic participants can only obtain the prompt through visual identification, which is easy to miss the prompt in the case of insufficient light, serious obstruction, bad weather or decreased driving attention, thereby increasing the risk of traffic.

[0003] On the other hand, the existing traffic information acquisition method highly depends on the mobile communication network. The navigation system, the prompt system and the vehicle-mounted equipment all need to exchange data with the Internet through the mobile communication base station, and in the case of base station offline, weak signal coverage or on-site power failure, the terminal equipment will not be able to obtain real-time updated warning information, resulting in that the emergency and sudden events cannot be delivered to the nearby vehicles or pedestrians in the first time. For example, in tunnels, mountain-sheltered road sections, remote areas or disaster scenes, the quality of mobile network is usually difficult to guarantee, and the traditional information pushing mechanism based on two-way communication link cannot meet the low-latency and high-reliability warning requirements.

[0004] In addition, in the scenes of road construction, vehicle breakdown, temporary road closure, debris flow, road waterlogging, traffic facility maintenance, etc., the events are sudden and temporary, and their positions are often not near the fixed basic communication nodes. If such scenes rely on the remote issuance of the central system, there are often problems of slow updating, large delay and even failure to deliver, which cannot form effective early warning to high-speed driving vehicles. In fact, construction personnel, emergency personnel or traffic management personnel often need to set reminders on site quickly, but are limited by the non-electric control facilities to actively send information, so that road users can only see the prompt when approaching the event area, thereby having a high risk of secondary collision. SUMMARY

[0005] The technical problem solved by the present application is to provide a near-field information transmission system and a use method, which can realize information delivery in the case of offline traditional base stations.

[0006] To solve the above technical problems, the technical scheme adopted by the present application is: A near-field information transmission system comprises a wireless communication transmission unit and an acquisition unit. The wireless communication transmission unit comprises a communication module, which is used to transmit target information conforming to a preset communication protocol to other wireless communication transmission units and / or acquisition units within a preset range. The acquisition unit is used to receive and decode the target information conforming to the preset communication protocol, and publish the target information.

[0007] To solve the above technical problems, another technical scheme adopted by the present application is: A use method of a near-field information transmission system is applied to the near-field information transmission system, and comprises the following steps: Generating target information based on an application scenario, and storing the target information in the wireless communication transmission unit. Acquiring a transmission range of the wireless communication transmission unit, and determining the installation quantity and installation position of the wireless communication transmission unit in the application scenario according to the transmission range. When detecting that the acquisition unit enters the transmission range of the wireless communication transmission unit, controlling the wireless communication transmission unit to transmit the target information to the acquisition unit. Controlling the acquisition unit to publish the target information.

[0008] The present application has the following beneficial effects: The present application provides a near-field information transmission system and a use method, which are composed of a wireless communication transmission unit and an acquisition unit. The former unidirectionally publishes target information conforming to a preset communication protocol to the surrounding area in a broadcast manner through a communication module, and the latter is responsible for receiving and decoding. This structure essentially changes the mode of traditional traffic warning relying on base station communication links. Since unidirectional transmission is adopted, a bidirectional connection does not need to be established, so information delivery can still be stably realized in the state of weak mobile communication signal, offline base station, network congestion or network disconnection. The wireless communication transmission unit can be quickly deployed at positions such as road construction zones, tunnel entrances and accident sites, without the need for complex configuration, and information publishing can be completed through a preset protocol. The acquisition unit is universal and can be a mobile phone, a vehicle-mounted device or other terminal with communication function, so that the system has wide coverage capability. The overall scheme provides early warning information through extremely low delay, which is suitable for high-speed driving scenes and also suitable for personnel passing environments, and significantly improves information accessibility and traffic safety in emergency situations.

DETAILED DESCRIPTION

[0010] To explain the technical content, the achieved purposes and effects of the present application in detail, the following will be described in combination with the embodiments and the accompanying drawings.

[0011] Technical terms involved in the present application are explained as follows:

[0012] To at least solve the above problems, please refer to Figure 1 The embodiment of the present application provides a near-field information transmission system, which comprises a wireless communication transmission unit 10 and an acquisition unit 20. The wireless communication transmission unit 10 comprises a communication module, which is used for transmitting target information conforming to a preset communication protocol to other wireless communication transmission units 10 and / or acquisition units 20 within a preset range. The acquisition unit 20 is used for receiving and decoding the target information conforming to the preset communication protocol, and publishing the target information.

[0013] From the above description, it can be seen that the present application has the following beneficial effects: The wireless communication transmission unit 10 and the acquisition unit 20 are used, the former unidirectionally publishes target information conforming to a preset communication protocol to the surrounding area in a broadcast mode through a communication module, and the latter is responsible for receiving and decoding. This structure essentially changes the mode of traditional traffic warning relying on a base station communication link. Since unidirectional transmission is adopted, a bidirectional connection does not need to be established, so that information delivery can still be stably realized in a state of weak mobile communication signal, base station offline, network congestion or network disconnection. The wireless communication transmission unit 10 can be quickly deployed at positions such as road construction zones, tunnel entrances and accident sites, without the need for complex configuration, and information publication can be completed through a preset protocol. The acquisition unit 20 is universal and can be a mobile phone, a vehicle-mounted device or other terminal with a communication function, so that the system has wide coverage. The overall scheme provides early warning information with extremely low delay, which is suitable for high-speed driving scenes and also suitable for personnel passing environments, and significantly improves information accessibility and traffic safety in emergency situations.

[0014] In some embodiments, the communication module comprises a reading element 11, a storage element 12, a control element 13 and a transmission element 14 connected by a circuit. The storage element 12 is used to store the target information and the preset communication protocol; The reading element 11 is used to select the target information to be transmitted; The control element 13 is used to analyze and process the target information and obtain target information that conforms to the preset communication protocol; The transmission element 14 is used to transmit the target information conforming to the preset communication protocol to other wireless communication transmission units 10 and / or acquisition units 20 within a preset range.

[0015] As described above, the collaborative roles of the reading element 11, storage element 12, control element 13, and transmission element 14 within the communication module are clearly defined, creating a structured link for the information generation, processing, and broadcasting process. The reading element 11 is responsible for selecting information, allowing the system to quickly retrieve pre-stored information based on the current situation. The storage element 12 stores target information and protocol content, ensuring the module can operate independently even without an external network. The control element 13 processes information according to a preset communication protocol, ensuring consistent information format and reliable encoding. The transmission element 14 is responsible for sending out the final information, achieving wireless broadcasting. This modular design enhances the system's stability in practical deployment scenarios, allowing construction personnel or traffic management personnel to complete encoding, setup, and dissemination without relying on external equipment. This circuit structure also facilitates embedded deployment on traffic cones, vehicle-mounted tripods, or fixed roadside facilities, providing continuous and effective early warning even in adverse weather conditions, tunnel obstructions, or curved road sections.

[0016] In some embodiments, the communication module further includes a WIFI component and / or a Bluetooth component; the transmission unit 14 transmits the target information conforming to a preset communication protocol to other wireless communication transmission units 10 and / or acquisition units 20 within a preset range via the WIFI component or Bluetooth component.

[0017] As described above, adding a WIFI or Bluetooth component to the communication module enables the transmitter 14 to broadcast target information based on widely used short-range wireless communication technologies. Since both WIFI and Bluetooth are mature, stable, and widely adopted, a large number of devices, including mobile phones and vehicle-mounted units, can receive broadcast information without additional hardware. In high-speed driving scenarios, WIFI's local broadcast characteristics can complete information delivery within milliseconds; in pedestrian scenarios, Bluetooth offers low power consumption and high anti-interference capabilities, providing stable and continuous identification. Using these common communication methods also allows deployed AP devices to operate without relying on customized protocol stacks, reducing on-site equipment costs. Utilizing WIFI's SSID broadcast characteristics, target information can be sent without a network connection, enabling the system to operate effectively in situations without mobile communication networks or with weak network coverage, improving the timeliness and reliability of emergency warnings.

[0018] In some embodiments, the communication module further includes a receiving element for receiving the target information transmitted from a preset external network; the control element 13 is used to analyze and process the target information and store it in the storage element 12.

[0019] As described above, the addition of a receiving element enables the communication module to obtain target information from a pre-set external network, process it through control element 13, and write it to storage element 12, thus achieving remote information updates. This structure allows the system to simultaneously support both local and centralized management modes. In scenarios requiring remote unified dispatch, such as road construction, disaster sites, and urban traffic management, control personnel can send the latest warning content to the AP device via an external network, reducing the time cost of manual updates on-site. Control element 13 formats the received information to ensure that the broadcast information matches the protocol, enabling the terminal device to parse it correctly. This capability allows the AP to not only broadcast traditional temporary information on-site but also act as a regional-level linkage early warning node, enabling multi-point synchronous dissemination, such as in situations involving continuous construction on multiple road sections or tunnel management, thereby enhancing the system's coverage and reliability.

[0020] Specifically, the aforementioned communication modules are either local area network (LAN) or large network (BN) type. The LAN type includes a LAN communication module, basically encompassing the functions of Wi-Fi (IEEE 802.11a / b / g / n / ac) and Bluetooth (IEEE 802.15.1): reading, storage, control, and transmission, all integrated into a single circuit module. In different application scenarios, the AP can be configured to use NB-IoT, LoRa, or LTE-V communication modes (not limited to these). The BN type, in addition to including all the functions of the LAN type, also allows connection to 3G, 4G, and 5G wide area mobile communication networks.

[0021] In some embodiments, the reading element 11 is a push-button switch or a DIP switch.

[0022] As described above, the reading element 11 is limited to a button switch or a DIP switch, enabling the AP device to quickly set the required broadcast content even without a screen, network, or complex interfaces. By selecting preset information in the storage element 12 via buttons or DIP switches, configuration can be completed within seconds by construction workers, traffic police, or on-site maintenance personnel after an emergency, reducing the possibility of misoperation. This physical input method is less affected by the environment and can operate reliably even in low temperatures, rain, dust, and vibration, making it suitable for deployment at road construction sites, tunnel entrances, or accident scenes. Compared to touch-screen devices, DIP switches or button switches offer advantages such as low cost, high durability, and simple maintenance, allowing the system to be used as an embedded module for traffic triangles, construction cones, and portable warning posts, improving on-site deployment efficiency and early warning coverage.

[0023] In some embodiments, the acquisition unit 20 is a mobile phone or vehicle-mounted unit with communication function. The mobile phone or vehicle-mounted unit is equipped with a preset program 22. The preset program 22 is used to receive and decode the target information that conforms to the preset communication protocol and publish the target information.

[0024] As described above, the acquisition unit 20 is clearly a terminal with communication capabilities, such as a mobile phone or vehicle-mounted unit, and receives, decodes, and publishes information through a preset program 22. This design allows the system to be widely adapted to a large number of existing terminals without the need for specialized receiving equipment, significantly reducing system implementation costs. In addition to parsing communication protocols, the preset program 22 can also provide feedback on received target information via text, voice, or vibration, enabling drivers or pedestrians to instantly perceive warning content even without paying attention to the screen. Furthermore, the stable power supply and fixed installation of vehicle-mounted units give them an advantage in long-term operation on high-risk road sections such as tunnels, bridges, and long downhill slopes; the widespread availability of mobile phones further improves information accessibility. This multi-terminal redundancy mechanism enhances the reliability of the warning system and helps reduce reaction time in high-speed traffic environments.

[0025] Specifically, the default program can be a dedicated app that decodes and displays images, text, voice, Beeper ringtones, vibrations, etc., according to the protocol. For acquisition units without a dedicated app, the default program can connect through a navigation system (such as Baidu or Gaode). If the navigation system is offline or has a weak mobile communication network, this system can still operate normally.

[0026] In some implementations, the communication module is equipped with NB-IoT, LoRa, or LTE-V communication modes.

[0027] As described above, the communication module can select from NB-IoT, LoRa, or LTE-V communication modes, allowing the system to adaptively adjust coverage radius, power consumption, and stability according to different application scenarios. NB-IoT features ultra-low power consumption and strong penetration, making it suitable for adverse environments such as tunnels and under bridges; LoRa can achieve kilometer-level propagation distances, enabling the formation of large-scale extended links between AP nodes; LTE-V is specifically designed for vehicle-to-everything (V2X) communication and is suitable for information exchange between high-speed vehicles. This interchangeability of modes allows manufacturers to flexibly configure the system according to local communication environments, improving its performance adaptability in different scenarios such as urban and rural roads, mountain roads, and urban tunnels. It also enhances the versatility of the AP module, facilitating future expansion and upgrades.

[0028] A method for using a near-field information transmission system, applicable to a near-field information transmission system, includes the following steps: Target information is generated based on the application scenario, and the target information is stored in the wireless communication transmission unit 10; The transmission range of the wireless communication transmission unit 10 is obtained, and the number and location of the wireless communication transmission unit 10 in the application scenario are determined based on the transmission range. When the acquisition unit 20 is detected to have entered the transmission range of the wireless communication transmission unit 10, the wireless communication transmission unit 10 is controlled to transmit the target information to the acquisition unit 20. The acquisition unit 20 is controlled to publish the target information.

[0029] As described above, the system provides a complete workflow from information generation and device deployment to early warning dissemination. Determining the number and location of devices based on the transmission range minimizes blind spots. Automatically transmitting target information when the acquisition unit 20 enters the range enables instant alerts without manual intervention. This workflow makes the system suitable for scenarios such as mobile construction, short-term road closures, emergency accident handling, and vehicle breakdowns. It allows for early-stage information broadcasting via APs to the surrounding area, reducing secondary accidents caused by limited visibility for drivers at high speeds. The automatic information dissemination mechanism of the acquisition unit 20 allows the terminal's alert method to adapt to different scenarios, such as using audio alerts at night or vibration alerts in tunnels, thereby enhancing perceptibility and safety.

[0030] In some embodiments, the step of controlling the wireless communication transmission unit 10 to transmit target information to other wireless communication transmission units 10 located within its transmission range is also included.

[0031] As described above, the process of adding target information transmission between APs effectively constructs a temporary chain relay network, enabling information to propagate further along the road. This chaining mechanism solves the problem of limited coverage of a single AP, forming a continuous early warning zone in curves, mountainous areas, and areas with multiple obstacles. For example, if an accident occurs ahead of a tunnel, information can be pushed to vehicles further away in advance through cascading forwarding across multiple APs, allowing them to take proactive measures. Compared to the traditional method that relies on central server scheduling, this local link does not depend on external communication networks, resulting in faster response times and continued operation even in scenarios such as disasters and power outages, improving system availability and resilience.

[0032] In some implementations, controlling the acquisition unit 20 to publish the target information specifically includes: The acquisition unit 20 is controlled to convert the target information into at least one of text, audio, or video for publication.

[0033] As described above, by converting target information into any of the following formats—text, audio, or video—the warning prompts become more perceptible and adaptable. In situations with high vehicle noise or distracted drivers, audio and vibration alerts effectively reduce the possibility of missed warnings; in complex road conditions, text and images provide more precise guidance. Multiple publishing modes meet the needs of different user groups, such as the visually impaired, hearing impaired, and those experiencing fatigue during long-distance driving, improving the system's versatility. This feature also enhances the consistency of AP broadcast information across different brands of mobile phones and in-vehicle units, ensuring that the acquisition unit 20 maintains a stable presentation even in environments with significant differences in interface design, thus guaranteeing the quality of critical warning information delivery.

[0034] Please refer to Figure 1 Embodiment 1 of the present invention is as follows: A Near Field Informatics System (N-Fi) is disclosed. This system comprises a wireless communication transmission unit 10 and an acquisition unit 20. It is used to broadcast early warning or alarm information to surrounding areas in situations with no public network coverage, limited communication, or complex on-site environments, thereby achieving rapid, secure, and low-latency information notification.

[0035] The wireless communication transmission unit 10 (AP) includes a communication module. The communication module integrates circuit components such as a reading element 11, a storage element 12, a control element 13, and a transmission element 14. It can be optionally equipped with a WiFi component, a Bluetooth component, or wireless communication modes such as NB-IoT, LoRa, or LTE-V, enabling the system to adapt well to different road scenarios. Specifically, the storage element 12 stores target information and preset communication protocols; the reading element 11 selects the specific information to be broadcast via a button switch or a DIP switch; the control element 13 encodes, verifies, and formats the information according to the protocol; and the transmission element 14 performs wireless broadcasting via WiFi or Bluetooth, enabling the acquisition unit 20, which conforms to the protocol, to receive the information within a preset range. In some embodiments, the communication module also includes a receiving element, which can obtain information from an external network and write it into the storage element 12, enabling remote information updates.

[0036] The acquisition unit 20 can be a terminal device with communication capabilities, such as a mobile phone, vehicle-mounted unit, or tablet computer. This terminal has a pre-set program 22 (APP or vehicle-mounted program) internally configured to receive and decode the target information sent by the wireless communication transmission unit 10, and to publish it in the form of text, audio, voice prompts, vibration, images, etc., according to the prompt requirements. The system can be deployed on a large scale without the need for dedicated receiving equipment, thereby reducing deployment costs and improving information reachability. Specifically, the acquisition unit 20 acquires the target information through the receiving antenna 21. Specifically, the pre-set program can be a dedicated APP, which decodes and displays images or text, voice, Beeper ringtones, vibration, etc., according to the protocol. For acquisition units without a dedicated APP, the pre-set program can connect through a navigation system (such as Baidu or Gaode). If the navigation system is offline or has a weak mobile communication network, the system can still operate normally.

[0037] During system operation, the wireless communication transmission unit 10 broadcasts target information to the surrounding area. Because the system uses a one-way communication method and does not rely on base station links, it can maintain stable operation even in situations with weak mobile communication signals, in tunnels, mountainous areas, construction zones, or disaster sites where network outages occur. When necessary, multiple wireless communication transmission units 10 can forward information to each other, achieving chain relay and enabling early warning information to propagate further along roads. This is suitable for complex environments such as tunnel entrances, curved road sections, and continuous construction areas, improving overall early warning coverage.

[0038] This system allows the Access Point (AP) to select the information to be published from the pre-stored AP module storage unit 12 using buttons or a DIP switch. The information is then analyzed and processed by the control unit 13 to obtain information conforming to the communication protocol, which is then sent to the wireless communication transmission unit 14. The network name (SSID) is published via IEEE 802.11a / b / g / n / ac, Bluetooth, NB-IoT, LoRa, or LTE-V at the base station (i.e., the AP), enabling wireless acquisition terminals that meet the communication protocol to receive the message in a one-way communication manner within the broadcast range. For large-scale networks, information can be integrated with the control center.

[0039] Embodiment 2 of the present invention is as follows: This embodiment provides a road construction early warning scheme based on a near-field information transmission system. Traditional navigation systems suffer from significant delays in information updates for dynamic events during road construction, such as pavement repair, ditch treatment, temporary obstacle removal, traffic sign installation, landscaping work, guardrail maintenance, and mudslides during the rainy season. Furthermore, they struggle to provide timely warnings to vehicles in situations with weak communication signals or power outages. This embodiment utilizes a wireless communication transmission unit 10 to achieve real-time near-field information broadcasting.

[0040] When a construction event occurs, on-site maintenance personnel can place the wireless communication transmission unit 10 at a key location on the road construction site. After the communication module within the wireless communication transmission unit 10 is activated, the reading unit 11 selects target information based on the code corresponding to the construction event; the control unit 13 processes the target information into a format conforming to a preset communication protocol; and the transmission unit 14 broadcasts the target information to an area within its preset transmission range via WiFi or Bluetooth. In this embodiment, the preset transmission range can reach approximately 500 meters.

[0041] The acquisition unit 20 can be a mobile phone or vehicle-mounted unit with a preset program 22 installed. When the acquisition unit 20 enters the transmission range of the wireless communication transmission unit 10, it can automatically receive and decode the target information, and publish the construction warning content in the form of text, audio, or vibration, so that vehicles and pedestrians can be informed of relevant information in time before approaching the construction area. The wireless communication transmission unit 10 can periodically rebroadcast the target information to improve the stability of information coverage.

[0042] Embodiment 3 of the present invention is as follows: In this embodiment, a near-field information transmission system is applied to emergency warnings in the event of a vehicle breakdown. According to road traffic safety management requirements, warning devices are typically placed behind the vehicle when a breakdown occurs. This embodiment integrates a wireless communication transmission unit 10 onto the vehicle or warning triangle, enabling the breakdown warning to cover a wider area via broadcast.

[0043] When a vehicle breaks down, the user can activate the warning triangle or the wireless communication transmission unit 10 in the vehicle terminal. After the communication module is activated, the reading unit 11 selects the target information corresponding to "vehicle breakdown warning"; the control unit 13 converts the information into a format that conforms to a preset communication protocol; and the transmission unit 14 broadcasts the target information to a preset transmission range via WiFi or Bluetooth.

[0044] Acquisition units 20 within this transmission range, including mobile phones, in-vehicle units, etc., can automatically receive and decode the breakdown warning information if they have a preset program 22 installed, and then broadcast the information to the driver via sound, vibration, or a display interface. Even if the acquisition unit 20 does not have the preset program 22 installed, the navigation application can still recognize the broadcast signal and alert the user. This embodiment allows a broken-down vehicle to instantly provide warning information to surrounding road users without relying on mobile network coverage, thereby reducing the risk of secondary collisions and improving driving safety.

[0045] Embodiment four of the present invention is as follows: In this embodiment, a near-field information transmission system is applied to accident early warning in tunnel areas. Tunnel spaces are enclosed and visibility is limited, making them highly susceptible to multi-vehicle chain-reaction accidents. Furthermore, mobile communication signals often attenuate or become interrupted in tunnels; therefore, an early warning system with independent broadcasting capabilities is required.

[0046] When an accident occurs inside the tunnel, or when special circumstances such as closure or congestion arise, on-site management personnel can deploy the wireless communication transmission unit 10 at a key location on the road outside the tunnel entrance (e.g., approximately 500 meters from the tunnel entrance). After the communication module is activated, the reading unit 11 selects the corresponding accident target information, the control unit 13 generates broadcast content conforming to a preset communication protocol, and the transmission unit 14 periodically broadcasts this information to the surrounding area via WiFi or Bluetooth.

[0047] The acquisition unit 20, once within the transmission range, automatically receives and decodes the accident information and alerts the user through display screens, voice prompts, or vibrations. This allows vehicles to be aware of the accident situation before entering the tunnel, enabling them to slow down or change routes in time. This embodiment effectively alleviates the blind spot problem caused by tunnel accidents, providing a safe buffer zone for subsequent emergency rescue.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
