基于霍尔传感的煤矿人员定位精度验证系统
|
摘要
针对煤矿人员定位精度静态测试方法自动化程度较低、时间和人力成本较高的问题,提出了基于霍尔传感的煤矿人员定位精度验证系统。该系统采用公共UDP接口对接不同厂家不同型号的定位基站,采用私有UDP接口传输霍尔传感设备的相关测距报文,采用生产-消费模型进行通信数据的采集、解析和入库;以霍尔测距结果作为基准数据,与定位基站采集的节点定位距离信息进行实时对比,从而验证定位系统的精度。测试结果表明,该系统自身最小测距误差率为0.80%,最大误差率为3.30%,平均误差率为1.38%,大大低于人员定位精度验证系统所允许的误差率5%。精度验证应用实例分析结果表明,该系统能够有效验证人员定位系统的精度。
In view of problems of low automation degree and high time and labor cost of static test method of mine personnel positioning accuracy,a mine personnel positioning accuracy verification system based on Hall sensing was proposed.The system uses public UDP interface to interface with different types of positioning base stations of different manufacturers,uses proprietary UDP interface to transmit related ranging messages of Hall sensing device,and uses production-consumption model to collect,parse and store communication data.The Hall ranging result is used as the reference data,and the node positioning distance information collected by positioning base station is compared in real time,so as to verify accuracy of the positioning system.The test results show that the minimum ranging error rate of the system itself is 0.80%,the maximum error rate is 3.30%,and the average error rate is 1.38%,which is much lower than the 5% error rate allowed by the personnel positioning accuracy verification system.The results of accuracy verification application example show that the system can effectively verify the accuracy of positioning system.
