Description

Digital solid mineral resource exploration and data acquisition internet-of-things transmission method and system Technical Field The invention relates to the technical field of solid mineral resource exploration, and particularly discloses a digital solid mineral resource exploration and data acquisition internet-of-things transmission method and system. Background Solid mineral resource exploration is an important basic work for guaranteeing national mineral resource safety and supporting industrial development, and in the current exploration work, data acquisition depends on various independent devices and manual recording modes, so that data formats of different sources are not uniform, acquisition time is not synchronous, and noise interference or key details are often caused in original information obtained on site. Meanwhile, due to complex mining area topography and severe communication conditions, the acquired data is difficult to stably and completely return to a rear command center, and the situation of data delay, loss or repeated round trip on-site verification often occurs. These problems prevent the explorationist from seeing a comprehensive, reliable field situation in time, and decisions are often developed based on incomplete information. The deeper technical contradiction is that the mining area environment puts very high demands on the reliability of data transmission, and the traditional communication means are difficult to simultaneously consider low power consumption, long distance, interference resistance and real-time performance. For example, in a drilling site of a mountain and a deep valley, key parameters such as inclination angle and grade change of a rock stratum acquired by a sensor need to be immediately transmitted to an analysis platform which is tens of centimeters, but on-site signals are weak, a base station is sparse, when a conventional wireless mode is adopted for transmission, a part of content of a data packet is often lost due to interference or disconnection, if a mode of manually carrying back after storage is changed, information lag is caused for days or even longer, so that subsequent operations such as profile connection, three-dimensional modeling and the like are forced to be suspended or repeated, and the whole investigation progress is seriously dragged. The contradiction between the acquisition instantaneity and the transmission reliability becomes the most prominent bottleneck for restricting the improvement of the exploration work efficiency. Therefore, how to realize accurate acquisition and reliable real-time transmission of geological data in complex mining area environment and keep the whole process data complete and consistent becomes a key problem to be solved urgently for digital investigation of solid mineral resources.
