Design of Portable Indicator for Underground Mines Using 433 MHz Wireless Communication

摘要

The mining industry is the backbone of various manufacturing and infrastructure industries. In order to maintain a safe working environment, a lot of parameters need to be monitored periodically in underground mines. Wired indicators in underground mines incur a lot of regular maintenance. In wired network, if the wire gets broken then data from multiple sensors may get damaged. In wireless communication, the environment of a certain area can be analyzed at a distance. This paper proposes a portable wireless indicator, which can display the measurement of various critical parameters of underground mines. The parameters that have taken into consideration are temperature, pressure, and humidity. This indicator can communicate with multiple transmitters at a time using an efficient polling multiple access methods.
