Identification and early warning system of abnormal operation status of electromechanical equipment group in coal mine

Abstract

The invention relates to a system for identifying and early warning the abnormal running status of a coal mine electromechanical equipment group. The system is characterized by comprising an air shaft substation, a master control system, a remote diagnosis system, a wireless acquisition module and a network service station, wherein the wireless acquisition module comprises a base station and nodes, the nodes comprise a vibrating temperature sensor, a DSP (digital signal processor) data process plate and a wireless transceiver module, the wireless transceiver module is connected with the base station by a wireless network, the base station is connected with the master control system by a ground looped network, and the master control system, the air shaft substation, the remote diagnosis system and the network service station are connected with one another by the ground looped network. According to the system, all the wireless nodes in the network are bidirectionally communicated with the base station, and the nodes are not communicated with one another. Compared with the other two networks, the star-type network has the advantages of being lowest in overall power consumption, easy to move, easy to spread, etc.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to an identification and early warning system for abnormal operation status of electromechanical equipment groups in coal mines. Background technique [0002] The coal mine electromechanical equipment group is an important equipment and material basis for the coal mine production industry, and has a large number of equipment and high power. Once these equipments break down and shut down, the mild ones will affect the output, and the severe ones will cause heavy casualties. Therefore, the safe, stable, 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 carries out offline instrumentation inspecti...

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.
