According to a safety hidden danger occurred when operation personnel no intention closed to the roadheader as a roadheader was in operation,even a personal safety accident occurred,a study on a danger area warning system of the roadheader was conducted. Based on an electromagnetic field theory as a base,a low frequency electromagnetic wave was applied to the medium of a distance measuring and a detection of electromagnetic wave strength and the three side positioning algorithm were applied to determine a location of the operation personnel in the underground mine and to judge the personnel in or not in the danger area. The STM32F103 embedded ARM was selected as a control chip. The system was composited with a centralized data processing device on the roadheader and the portable mobile monitoring and measuring device with the operation person. With a simulation experiment measurement of the prototype,in a personnel positioning judgement within 0. 5 ~ 4. 0 m,an average error was 4. 3% and a danger area positioning and warning could be realized.
