Early warning system of mining device

Abstract

The invention relates to an early warning system of a mining device. The early warning system is characterized in that the early warning system comprises a ventilating shaft branch station, a main control system, a remote diagnosis system, a wireless acquisition module and a network service station; the wireless acquisition module comprises a base station and a node; the node comprise a vibration temperature sensor, a DSP data processing plate and a wireless transceiving module; the wireless transceiving module is connected with the base station through a wireless network; the base station is connected with the main control system through a ground ring network; and the main control system, the ventilating shaft branch station, the remote diagnosis system and the network service station are mutually connected together through the ground ring network. According to the invention, all wireless nodes in the network carry out bidirectional communication with the base station and fail to communicate with each other; and compared with other two kinds of networks, a star type network is advantageous in that the whole power consumption is lowest and the star type network is easy to move and expand.

Description

Technical field [0001] The invention belongs to the field of network technology, and specifically relates to an early warning system for mining equipment. Background technique [0002] The coal mine electromechanical equipment group is an important equipment and material foundation of the coal production industry, and the number of equipment is large and the power is large. Once these equipment break down and shut down, the lighter ones will affect the output, and the more serious ones will cause serious casualties. Therefore, the safety, stability, long-term, full-load, and high-quality operation of large-scale key equipment is not only related to the economic benefits of the enterprise, but also related to mine production safety and social harmony. At present, even if some large-scale electromechanical equipment is equipped with some fault backup protection functions, or carry out off-line instrument inspection methods, there are still shortcomings: on the one hand, a lot of m...

AI Technical Summary

Problems solved by technology

However, it started relatively late in the coal mine industry, and the technology is immature. In particular, there are basically no products in the networked system for identification and early warning of abnormal operation status of large electromechanical equipment groups in online coal mines based on wireless sensor network technology.
