Description

Technical Field

[0001] The present invention relates to the technical field of smart communities, and in particular to a V2X smart community system. Background Art

[0002] In recent years, intelligent transportation systems (ITS) and smart community technologies have gradually attracted attention, especially the application of V2X (Vehicle-to-Everything) communication technology, which provides new ideas and means to solve these problems. V2X technology aims to improve road safety, optimize traffic flow, improve environmental quality and enhance the quality of life of residents through information exchange between wireless communication technologies. However, the current V2X technology is mainly focused on a single application scenario, such as traffic signal optimization or emergency rescue, and lacks a comprehensive smart community system to fully integrate and manage these functions. Although some existing intelligent transportation systems can provide certain traffic management and services, they still have deficiencies in data sharing, multi-modal traffic integration, environmental monitoring and public safety. In addition, these systems often rely on a single communication technology and platform, making it difficult to achieve cross-platform and cross-system interconnection, which limits their effectiveness and scope in practical applications. Summary of the invention

[0003] In order to solve the above-mentioned problems of the prior art, the present invention provides a V2X smart community system, which aims to achieve comprehensive integration of intelligent traffic management, environmental monitoring, public safety, energy management and community services within the community through all-round communication between vehicles, vehicles and infrastructure, vehicles and pedestrians, and vehicles and networks.

[0004] A V2X smart community system comprises a central management module, a V2X communication module, a functional module and a sensor network; the central management module connects the functional module and the sensor network via the V2X communication module;

[0005] The central management module is used for data processing, analysis and storage;

[0006] The V2X communication module integrates different communication modules through protocol conversion and adaptation;

[0007] The sensor network collects images, air quality, and noise of the community through sensor devices;

[0008] The functional module transmits the data collected from various sources to the central management module through the V2X communication module and the sensor network, and receives the results processed and analyzed by the central management module to implement the corresponding functions.

[0009] Furthermore, the V2X communication module includes a protocol conversion unit, an adaptation unit and a message queue; the protocol conversion unit is used to convert the data of the wireless network protocol into data based on the TCP / IP protocol; the adaptation unit integrates different communication modules and performs adaptation processing according to the hardware protocol; the message queue is used to decouple the dependencies between different communication modules.

[0010] Furthermore, the specific conversion process of the protocol conversion is:

[0011] According to the content and rules of the protocol, define the corresponding mapping rules to map the elements in the source protocol to the target communication protocol one by one;

[0012] Create a mapping table to record the unique identifier of each physical device under different protocols;

[0013] Write a parser to decode the data received from the source protocol according to the mapping rules, and use the generator to reconstruct the data packets according to the requirements of the target communication protocol;

[0014] Using JSON or XML as an intermediate representation ensures that all types of data can be processed consistently.

[0015] Furthermore, the adaptation unit implements the overall adaptation process as follows:

[0016] Select the appropriate node RF operating frequency band according to the target communication protocol;

[0017] Design hardware nodes that support various communication protocols and equip the hardware nodes with corresponding communication interfaces to connect different communication modules;

[0018] Develop corresponding drivers for each communication module, write initialization functions, set basic parameters of the communication module and integrate them into the general driver framework, and encapsulate the operations of each communication module to simplify the calling logic of upper-level applications to different communication modules;

[0019] Implement its standard protocol stack for each communication technology.

[0020] Furthermore, the V2X communication module and the central management module transmit data through an API gateway and a standardized data interface; the standardization process of the data interface is specifically as follows:

[0021] Define a common data model;

[0022] Use a set of RESTful API service endpoints to receive and send standardized data for pre-processing;

[0023] Formulate association rules from raw data to standard formats, write scripts or configuration files to automatically complete the conversion, and use deep learning models to perform data fusion processing;

[0024] Use middleware software as a bridge to translate between different protocols and distribute to the corresponding nodes through the communication gateway for data upload.

[0025] Furthermore, the implementation process of decoupling in the message queue is as follows:

[0026] Design an application responsible for collecting data from various sensors or devices, formatting it into messages suitable for message queues, and ensuring that the messages conform to the predefined data model and contain necessary metadata; send the formatted messages to the message queue server, and the switch distributes them to the corresponding queues according to the Routing Key;

[0027] Deploy consumer applications, listen to messages in specific queues, configure multiple consumer instances to process messages in parallel, and introduce a cache mechanism to temporarily store frequently accessed data to reduce delays caused by repeated queries.

[0028] According to the target communication protocol, the message format is reconstructed and context information is attached. At the same time, a confirmation mechanism is set up to ensure that the message is successfully delivered and processed.

[0029] Furthermore, when the V2X communication module transmits data to the central management module, encryption technology and anonymization processing are used to protect data privacy, and firewalls and intrusion detection are set up to prevent illegal intrusion.

[0030] The beneficial effects of the present invention are as follows: the present invention proposes an efficient and intelligent smart community system, which can significantly improve the operational efficiency and service quality in multiple fields such as urban traffic management, environmental monitoring, public safety, energy management and community services; by integrating V2X communication technology, it not only realizes cross-platform and cross-system interconnection, ensures efficient sharing and utilization of data, strengthens the collaborative operation capabilities between various functional modules, but also realizes accurate analysis and rapid response to massive real-time data, effectively promoting the construction and development of smart cities.

[0051] 2. Communication module adaptation: Integrate different wireless communication technologies at the receiving end of the device and adapt them according to different hardware protocols;

[0052] 1. Select the appropriate node RF operating frequency band (e.g. 2.4GHz, 868MHz, 915MHz) according to the target communication protocol. Different frequency bands have different effects on transmission distance, penetration ability and power consumption.
