Architecture and Key Technologies of Mine Internet of Vehicles

As the important equipment of mine production, the level of mine vehicles management has a direct impact on all aspects of production, safety and management of mine. The application of IoV(internet of vehicles) to improve the intelligent level of mine vehicle management is an important part of intelligent mine construction. In order to avoid the problems of scattered development, repeated construction and difficult system integration caused by unclear concept, different objectives, different paths, different system architecture and different technical application emphases in the application of IoV in the mine vehicle management, taking the intelligent coal mine as an example, the concept of MIoV (mine internet of vehicles) is proposed, and its system architecture, key technologies and typical applications are analyzed and discussed. Firstly, on the basis of reviewing the development of intelligent mine and IoV, the concept of MIoV is defined and expounded; secondly, referring to the architecture of IoV and MIoT (mine internet of things), the architecture of MIoV is designed, which is composed of sense and control layer, network layer, service support layer and application layer; the key technologies of MIoV and intelligent mine information system are integrated and analyzed key technologies such as positioning and monitoring, intelligent perception and control, wireless communication, collaborative computing. Finally, from the four aspects of human-vehicle-environment-management, mine vehicle and driver monitoring, mine vehicle automatic driving and driverless, mine safety monitoring based on mine vehicles, mine vehicle intelligent scheduling and other typical application of MIoV are discussed. The research results laid a foundation for the construction of MIoV to promote the in-depth and orderly application of IoV in intelligent mine vehicle management, enrich the technical connotation of MIoT, and accumulate experience for the application of other technology branches of MIoT in intelligent mine construction.
