【摘要】：近几年来,国家越来越重视煤矿的安全和监管力度,而对于山西来说,煤炭开采业的安全尤为重要。因此,我们必须提高管理的水平,同时要确保煤矿安全高效生产,并且对于管理者和经营者,他们需要知道实时动态的人员分布,准确的数量差异,同时需要总结特殊类型的人员活动跟踪等。井下作业的环境和地形相对较差,无法跟踪和检查员工考勤,很多事情都是不可避免的,提前做好人员、人员定位系统可以保证技术的准确性。同时,在危险或意外的事件发生时,我们如何才能及时和准确的找到人员定位变得十分重要。本文通过对GPS、蓝牙、超宽带、射频识别、WLAN定位、计算机视觉等无线通信技术的分析与比较,选择红外定位技术作为人员定位系统的通信技术。同时本文在一种基于AOA定位算法中,利用其精确定位逆向思维进行进一步精确运算。通过对于环境参数的动态采集运算,提高了定位算法的定位精度。由于目前数据库的提取速度以及存储数据的容量都无法达到理想的状态,本人本科学习计算机专业,故对于数据压缩方面做了一些研究,并且提高了压缩率,设计并实现了一个对井下人员定位方法,并且通过模拟实验和仿真实验验证了数据压缩的可行性,并且后续还对进一步研究计划做了展望。
[Abstract]:In recent years, the state has paid more and more attention to the safety and supervision of coal mines, and for Shanxi, the safety of the coal mining industry is particularly important. So we have to improve the level of management, and at the same time make sure that coal mines are safe and efficient, and for managers and managers, they need to know the dynamic distribution of people in real time, the exact number of differences, At the same time, it is necessary to summarize the special type of personnel activity tracking and so on. The environment and topography of underground work is relatively poor, and it is impossible to track and check the attendance of staff. Many things are inevitable. The personnel positioning system can ensure the accuracy of the technology. At the same time, in the event of dangerous or unexpected events, how we can find people in time and accurately becomes very important. Based on the analysis and comparison of wireless communication technologies such as GPS, Bluetooth, UWB, RFID WLAN positioning and computer vision, this paper selects infrared positioning technology as the communication technology of personnel positioning system. At the same time, in an AOA-based localization algorithm, the exact location of the reverse thinking is used to perform further accurate operation. The location accuracy of the location algorithm is improved by the dynamic acquisition of environmental parameters. As the speed of database extraction and storage capacity can not reach the ideal state, I studied computer science, so I have done some research on data compression, and improved the compression ratio. A positioning method for underground personnel is designed and implemented, and the feasibility of data compression is verified by simulation and simulation experiments, and the further research plan is prospected.
