Dynamic displacement monitoring system for equipment chamber base plate of underground coal preparation plant

Abstract

The invention discloses a dynamic displacement monitoring system for an equipment chamber base plate of an underground coal preparation plant. The dynamic displacement monitoring system comprises sensor nodes, SINK nodes, a base station and a monitoring host unit, wherein the sensor nodes, the SINK nodes and the base station are arranged in a well; the monitoring host unit is arranged on the well; the sensor nodes are wirelessly connected with the SINK nodes; the SINK nodes, the base station and the monitoring host unit are connected through wires. The dynamic displacement monitoring system for the equipment chamber base plate of the underground coal preparation plant based on ZigBee can be used for monitoring equipment foundations in an equipment chamber of the underground coal preparation plant to fulfill the aim of monitoring the displacement of the chamber base plate. The system is low in power consumption, high in reliability, high in sensitivity, easy to integrate and resistant to a severe industrial environment; the installation of the nodes cannot affect the operation of equipment and passing of people, and cannot damage the integrality and the stability of the equipment foundations.

Description

technical field [0001] The invention relates to the technical field of displacement monitoring of an underground coal preparation plant, in particular to a dynamic monitoring system for the displacement of an equipment chamber floor of an underground coal preparation plant. Background technique [0002] Coal is the most important primary energy in my country. With the increase of gangue discharged from coal mining at a rate of 150 to 200 million tons per year, on the one hand, coal preparation in the mine increases the transportation cost of gangue in raw coal and the cost of gangue discharge, resulting in tension in the mine's lifting capacity. On the other hand, waste rock discharge occupies land, causing pollution of the ground environment, which is not conducive to the improvement of the living environment. In February 2009, Xiezhuang Mine of Shandong Xinwen Mining Group built the first coal washing plant in China. Before the raw coal was lifted into the shaft, the gangue...

AI Technical Summary

Problems solved by technology

[0007] 1. There is no wireless transmission device in the prior art, and it does not have the function of wireless data transmission and reception, and cannot realize the dynamic monitoring of the displacement of the bottom plate of the equipment chamber of the coal preparation plant;

[0008] 2. The size of the existing technology is large, and the installation of this technology will affect the operation of the equipment in the coal preparation plant and the normal passage of the operators;

[0009] 3. The existing technology cannot be installed on the basis of coal preparation equipment. By drilling and installing on the basis of equipment, it will not only destroy the integrity and stability of the equipment foundation, but also affect the operation of coal preparation equipment;

[0010] 4. The cost of the existing technology is relatively high, and the fiber grating network analyzer used is expensive, which is not suitable for popularization and use in mines;

[0011] 5. The transmission of sensor monitoring signals in the prior art relies on wired optical fibers. It is necessary to lay optical fibers in underground passages, which takes up a lot of space, and the lines age quickly and are easily damaged, resulting in a high accident rate.
