Development of a Sensor-connected Smartphone Application for Information Sharing Between Haulage Vehicles in Mines

In this study, we developed a smartphone application that acquires and shares surrounding information from haulage vehicles using various sensors to prevent problems at mine sites. A light detection and ranging sensor and an accelerometer in a smartphone were used to detect the road surface conditions at a mine site, and a dust sensor and gas sensor were used to measure the atmospheric environment. To detect the location of the vehicle, the global positioning system function of the smartphone was utilized. Experiments at the Kangwon National University Samcheok campus and a mine site of Taeyoung EMC confirmed that the data from each vehicle could be shared in real time. In addition, sections with poor road surface and high dust density were identified. It is expected that the technology developed in this study can be used to improve the mine environment.
