Abstract: In view of the existing well detection methods and devices, the detection effect is not ideal, the detection efficiency is low, and the detection results are not accurate. This paper proposed a unique detection technology scheme based on finger vein recognition. For the first time, finger vein recognition technology is introduced into the field of coal mine entry detection. Relying on the UWB personnel positioning system, the UWB identification card and finger vein recognition technology are used for the identification and uniqueness detection of coal mine entry. On the test surface, compared with the iris based well entry detection device, the scheme can effectively improve the well entry detection efficiency in the case of a large number of people entering the well, which is 38.9%.
