V2X (Vehicle-to-Everything wireless communication technology) originated in 2006 and has now become one of the hottest concepts in the tech community. V2X is a technology that enables the interconnection of vehicles with everything, utilizing wireless communication and sensor technologies to achieve real-time connections and information exchange between vehicles to vehicles (V2V), vehicles to infrastructure (V2I), vehicles to pedestrians (V2P), and vehicles to the cloud (V2C). It is generally believed that V2X needs to go through three stages of development to ultimately achieve an information environment layout for fully automated driving.
-
The first stage: Early vehicular communication systems were mainly through vehicle terminals communicating with infrastructure, known as Vehicle Infrastructure Communication Systems (VICS). It initially broadcasted traffic information, such as road conditions, traffic accidents, and traffic light information.
-
The second stage: With the rapid development of wireless communication technology, communication between vehicles has also been enhanced. V2V communication systems can transmit real-time data between vehicles through short-range communication technologies (such as 802.11p/WAVE), achieving information interaction between vehicles. This stage of the V2X system is mainly used to provide safety warnings and driving decision support for vehicles.
-
The third stage: Due to the development of vehicle intelligence and automation, the demand for information exchange between vehicles continues to grow. V2X gradually evolves towards vehicle autonomous driving technology. This stage's V2X system includes communication between vehicles and infrastructure (V2I), vehicles and pedestrians (V2P), etc., to achieve higher levels of vehicle autonomous driving and traffic management.

Key Technologies of V2X Communication
-
RF Monitoring Technology: V2X communication systems rely on wireless RF technology for information transmission, making RF monitoring technology a key support. In V2X applications, real-time monitoring and analysis of V2X signals are essential to ensure signal strength and stability, thereby improving communication reliability.
-
Packet-based Communication Technology: V2X communication systems use packet-based communication methods, i.e., information exchange through packet encapsulation. This communication method has high timeliness and flexibility, capable of adapting to complex and variable traffic environments. Using packet-based communication technology allows for detailed monitoring and analysis of the communication process, optimizing communication protocols and algorithms, and enhancing system performance.
-
Wireless Communication Technology: The core of V2X communication technology is wireless communication technology, including short-range communication technologies (such as Bluetooth, Wi-Fi, DSRC, etc.) and long-range communication technologies (such as cellular network technologies like 4G, 5G, etc.). These wireless communication technologies provide vehicles with high-speed, reliable communication links, achieving information exchange with the surrounding environment.
-
Sensor Technology: V2X communication technology needs to be integrated with various sensors (such as radar, LiDAR, cameras, etc.) to perceive and understand the surrounding environment. These sensors can provide rich environmental information, such as vehicle location, speed, direction, obstacles, etc., offering data support for V2X communication.
-
Information Processing and Analysis: V2X communication technology requires the processing and analysis of collected information to extract useful information and make decisions. This includes data fusion, target detection and tracking, route planning, etc. These technologies are significant for improving the accuracy and reliability of V2X communication.
-
Security and Privacy Protection: V2X communication involves a large amount of sensitive information, such as vehicle location, speed, etc., necessitating the security and privacy protection of the communication process. This includes encryption technology, digital signatures, access control, etc., to prevent information theft or tampering.
-
Standardization and Interoperability: To promote the widespread application of V2X communication technology, corresponding technical standards and specifications need to be developed to ensure interoperability between devices from different manufacturers and different countries/regions. This includes wireless communication technology standards (such as 3GPP, IEEE, etc.), application layer protocol standards (such as CoAP, HTTP, etc.), etc.
02 Current Application of V2X Technology in Mining
Currently, the application of V2X in mining mainly focuses on excavator scheduling and mine truck transportation. Through V2X technology, excavators can communicate with mine trucks in real-time, passing on excavation tasks and work progress information to the mine trucks. At the same time, excavators can also obtain the location and loading status information of the mine trucks. Operation personnel can adjust the loading distance between them through the excavator's onboard smart tablet, thereby reducing the waiting time for excavators and mine trucks and improving production efficiency. Additionally, through V2X technology, excavators can monitor the surrounding environment in real-time, such as the location of other equipment and personnel, to ensure safe operations.
Mine trucks communicate in real-time with excavators, other mine trucks, and infrastructure through V2X technology, obtaining transportation tasks and road condition information. Mine trucks can choose the optimal driving route based on this information, avoiding congestion and hazardous sections. At the same time, mine trucks can also pass on their location and loading status information to excavators and other mine trucks, and other mine trucks can adjust their driving routes and speeds based on the location and driving status of the mine trucks. This can improve the transportation efficiency and safety of mine trucks.
