Embodiment

[0043] The dam stability evaluation of a tailings pond is carried out, and the stability calculation results under different working conditions are analyzed by the limit equilibrium method. Select the section with the smallest stability coefficient under flood operating conditions to lay out the monitoring points of the infiltration line.

[0044] Then carry out the data analysis and comparison of the on-line monitoring point of the infiltration line, wherein the historical curve of the infiltration line monitoring point of the minimum safety factor infiltration line monitoring profile; the historical curve of the infiltration line monitoring point of the common monitoring profile; The infiltration line changes significantly, and the upward and downward trends are prominent.

[0045] After the monitoring points are laid out, install the device of the present invention based on the zigbee wireless networking technology for monitoring the infiltration line of the tailings pond. ...

Abstract

The invention discloses a tailings reservoir saturation line on-line monitoring point layout and zigbee networking structure. A tailing dam stability monitoring analysis profile of vertical axis of dam is established; stability analysis of each dam profile is carried out under flood routing operating conditions by a limit equilibrium method, the dam profile with the minimum stability coefficient is selected as a main saturation line monitoring profile, and no fewer than 4 monitoring points are laid; other profiles are used as auxiliary monitoring profiles, and each profile has fewer than 2 monitoring points; through a saturation line acquisition instrument, teletransmission based on zigbee wireless networking as the core is established to complete acquisition, monitoring and transmission of field data; automatic query of partial nodes, display of database lists and display of graphic images are realized through management software of a central monitoring computer; and packet loss ratio is obtained through comparison between transmit data and receive data, and stability of the lay-out method is determined. The invention has characteristics of clear priority, emphasis on key points, few monitoring points, reliable transmission and analysis accuracy.

Description

technical field [0001] The patent of the invention belongs to the technical field of mine monitoring, and is applicable to the layout of online monitoring points of the infiltration line of tailings ponds and zigbee wireless networking devices. Background technique [0002] In recent years, there are more and more online monitoring technologies for tailings ponds, especially the method of monitoring the infiltration line. But there is no research on the layout of monitoring points, most of them are evenly arranged according to the specifications, and the on-site monitoring method adopts wired monitoring method, and some wireless ones use network bridge monitoring. The wired monitoring method is unfavorable for post-maintenance, and the cost of network bridge monitoring is relatively high. [0003] The layout of online monitoring points for the infiltration line of the tailings pond and the zigbee wireless networking device, based on the stability analysis results of the dam...
