Abstract: Mine vehicles are important equipment for mine production, and their management level directly affects all aspects of mine production, safety, and operation management.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 decentralized development direction, repeated construction investment and difficulty in system integration caused by unclear concepts, different objectives, different paths, different system architectures and different technical application priorities in the application of IoV in mine vehicle management,the intelligent coal mine was used as an example in this paper.It proposed the concept of MIoV(Mine Internet of Vehicles)and analyzed its system architecture, key technologies as well as typical applications.Firstly, on the basis of reviewing the development of intelligent mines and IoV, MIoV is defined and expounded.Secondly, with reference to the architecture of IoV and MIoT, the architecture of MIoV is designed, consisting of perceptual control layer, network layer, service support layer and application layer; and then with the combination of the MIoV key technologies and intelligent mine information system, the key technologies are analyzed, such as positioning and monitoring,intelligent perception and control,vehicle wireless communication,and collaborative computing.Finally, from the four aspects of “people, vehicle, environment and management”, the typical application of MIoV were discussed, such as mine vehicle and driver monitoring, mine vehicle automatic driving and unmanned driving, mine safety monitoring based on mine vehicles, mine vehicle intelligent scheduling.The research results laid a foundation for promoting the in-depth and orderly application of IoV technology in intelligent mine vehicle management, while enriching the technical connotation of MIoT, and accumulating experience for the application of other technical branches of MIoT in the intelligent mine construction.
