摘　　要：为提高矿山井下空间定位的准确性,应用物理模拟和计算机模拟等研究方法对基于接收信号强度指示(RSSI)测距的定位算法进行了研究。针对井下工程布置和生产环境特点,基于物联网理论和技术,设计了试验流程和试验装置。进行了基于ZigBee的硬件平台的井下RSSI测距试验、三边测量定位试验和实验室BP神经网络定位试验,并根据试验数据的均方误差确定了组合权值,进行了定位精度调整。试验结果表明,运用组合定位精度调整模型对定位数据进行处理后,有效地降低了异常数据对定位结果的影响,提高了定位结果的准确性和稳定性。In order to improve the accuracy of mine underground space positioning, the study of position algorithms based on RSSI distance measurement was carried out by using physical simulation and computer simulation. Based on characteristics of the engineering layout and the operational environment of the underground mine, the experimental process and devices were designed based on the theory and technology of the internet of things. The RSSI distance measurement experiment based on ZigBee hardware platform was carried out, as well as the trilateral measurement and positioning and the position experiment of BP neural network in the laboratory. According to the mean square error of the test data, the combined weight was determined and the positioning accuracy was adjusted. The experimental results show that after the combined positioning accuracy adjustment model is used to process the positioning data, the influence of abnormal data on the positioning results is effectively reduced, and the accuracy and stability of the positioning results are improved.
