Abstract: 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.
