在煤矿井下移动目标定位系统中,设计可靠的、并发识别能力好的无线通信方案,可以有效减少定位系统的漏读率,提高系统的可靠性,从而达到提高矿井移动目标定位系统性能。结合矿井定位系统性能的要求,围绕定位系统中标签漏读率展开研究,在分析矿井定位的无线通信技术及其对漏读率影响的基础上,设计了"时间片调度"算法以减小漏读率,随后根据数学建模和概率计算的方法计算出碰撞概率和漏读率。

In the coal mine underground mobile target location system,designing a wireless communications solution which has great ability to identify concurrent can effectively reduce the leakage read rate and improve system reliability,so as to improve system performance of coal mine mobile target location system.Combining with performance requirements of the mine positioning system,revolving around the leakage read rate of tags in the mine position system,on the basis of analyzing the wireless communications technology for positioning system and its influence on leakage read rate,the paper designed the ＂time slicing schedule＂ method to reduce the leakage read rate,and calculated the wireless collision probability and leakage read rate by mathematical modeling and probabilitycalculation.
