Abstract

At present, due to their geographical distribution, environmental conditions and traditional monitoring technologies, the manual inspection of brine pumps in Qinghai Saline Lake can not be effectively carried out in real time, so the pumps have a high failure rate. This has seriously affected the chemical production of this saline lake. The paper designed a remote real-time monitoring terminal and a decision support system based on LoRa technology, GPRS (General Packet Radio Services) remote communication technology and remote-control technology. The system integrated the liquid-level sensing model and the decision support model for brine pump management. The system monitored and analyzed the voltage, current, and liquid-level parameters in real time to determine the operating status or failure of the brine pump. The ID3 (Iterative Dichotomiser 3) method was used to establish the correlation models between the dynamic monitoring information and the brine pump failure, which is the core of the decision support model. The remote controller was implemented to display and control the running status of the brine pumps when the maintenance personnel received the warning information. PHP (Hypertext Preprocessor) language and a MySQL database were implemented to realize the data display, management and decision support system.

Highlights

Salt lake resources, as an important part of China’s mineral resources, contain rich inorganic salt resources, which are formed from liquid minerals in the unique natural geographical environment
Qinghai salt lake resources are located in Qaidam Basin, affected by the storage conditions of underground brine, water physical properties, hydraulic characteristics and distribution, and the mining area is vast and the brine pumps are disperse [1,2]
The brine pump is responsible for extracting the underground brine from the brine well to the surface and is scattered throughout various mining areas, which increases the difficulty of the daily management

Summary

Introduction

As an important part of China’s mineral resources, contain rich inorganic salt resources, which are formed from liquid minerals in the unique natural geographical environment. Qinghai salt lake resources are located in Qaidam Basin, affected by the storage conditions of underground brine, water physical properties, hydraulic characteristics and distribution, and the mining area is vast and the brine pumps are disperse [1,2]. According to the burial characteristics of the underground brine and the water-rich level of the aquifer, salt lake chemical enterprises realize the large-scale exploitation and utilization of the underground brine by adopting well-mining technology [3]. The brine pump is responsible for extracting the underground brine from the brine well to the surface and is scattered throughout various mining areas, which increases the difficulty of the daily management
