Abstract
This paper describes a wireless real-time monitoring system (MS-BWME) to monitor the running state of pumps equipment in brine well mining and prevent potential failures that may produce unexpected interruptions with severe consequences. MS-BWME consists of two units: the ZigBee Wireless Sensors Network (WSN) unit and the real-time remote monitoring unit. MS-BWME was implemented and tested in sampled brine wells mining in Qinghai Province and four kinds of indicators were selected to evaluate the performance of the MS-BWME, i.e., sensor calibration, the system's real-time data reception, Received Signal Strength Indicator (RSSI) and sensor node lifetime. The results show that MS-BWME can accurately judge the running state of the pump equipment by acquiring and transmitting the real-time voltage and electric current data of the equipment from the spot and provide real-time decision support aid to help workers overhaul the equipment in a timely manner and resolve failures that might produce unexpected production down-time. The MS-BWME can also be extended to a wide range of equipment monitoring applications.
Highlights
Underground brine, which contains many kinds of mineral deposits such as potash, magnesium, sodium, lithium, etc. is an important raw material for chemical products such as salt, potash fertilizer, lithium carbonate, etc. [1,2,3,4]
Based on the literature review, this paper presents a novel application: a wireless real-time monitoring system (MS-BWME) that aims to monitor brine well mining equipment by acquiring and transmitting the real-time voltage and electric current data of the pump equipment from the site, helping workers deal in a timely way with the situation on the spot, overhaul the equipment, and resolve any failure that might produce unexpected production interruptions
The system transmission performance was evaluated by judging whether the sensor data were transmitted to the remote monitoring end in real-time, and whether the data reflected accurately the running state of the pump equipment
Summary
Underground brine, which contains many kinds of mineral deposits such as potash, magnesium, sodium, lithium, etc. is an important raw material for chemical products such as salt, potash fertilizer, lithium carbonate, etc. [1,2,3,4]. In [26], based on the technologies of condition monitoring and modern communication network, an integrated system is developed for monitoring the key running parameters of mining equipment. One kind of promising technology, the Wireless Sensors Network (WSN), by integrating micro-sensor technology, embedded computing, wireless communication technology with information processing, can sense and acquire information about monitored objects in their environments using sensors, record and transmit data to a base station for further processing through wireless networks [27,28,29,30,31]. Based on the literature review, this paper presents a novel application: a wireless real-time monitoring system (MS-BWME) that aims to monitor brine well mining equipment by acquiring and transmitting the real-time voltage and electric current data of the pump equipment from the site, helping workers deal in a timely way with the situation on the spot, overhaul the equipment, and resolve any failure that might produce unexpected production interruptions.
