Safety scheme for mining industry using zigbee module

Abstract

This work proposes a safety scheme for coal mining industry using sensors and zigbee. The zigbee built safety scheme with precise remote monitoring and tracking is the most suitable life saving system for underground mining environment. The LPC2148 based underground sensor module continuously monitors and transmits data to the tracking module using zigbee. The PIC protective device wore by labor helps to identify their location using zigbee and the associated limit switch alerts labor in case of improper wearing of PPE. The voice unit attached to underground sensor module gives an emergency command based on the analysis of monitored parameters. In addition the tracking module helps to locate workers through the signal relayed by zigbee protective device. Thus the safety system for coal mining regions with ability to track and alert via voice command forms a complete protective system for underground labors.
