Design of Position Monitoring System
To rescue trapped workers and reduce death rate in mine tragedies, a novel position monitoring system for mine workers is proposed. This monitoring system adopts wireless communication technology avoiding the influence of temperature instability, poor light and humidity. A C51 chip and a single chip radio transceiver nRF2401 are consist of a position monitoring system to enhance its security and lessen its loss.
