Description

Well personnel go in and out detection device Technical Field The utility model relates to the technical field of well entry and exit detection of mine personnel, in particular to a well entry and exit detection device for mine personnel. Background The well entry and exit detection of the mine personnel is realized by arranging a special recognition device at a well mouth of the mine to rapidly and accurately recognize and record the identities of the well entry and exit personnel, standardizing the station positions of the personnel by using a station limiting device, adjusting the height of detection equipment by matching with a lifting device so as to adapt to the personnel with different heights, and processing and analyzing the acquired data by combining with an intelligent analysis device, thereby realizing effective monitoring and management of the well entry and exit condition of the mine personnel. The prior art patent CN222105989U discloses a well entry recognition device for mine wellhead personnel, which comprises a supporting underframe, wherein an iris detection device is arranged at the top of the supporting underframe and used for recognizing the iris of the well entry personnel, a limiting station device is arranged at the front side of the supporting underframe, a lifting device is arranged at the top of the supporting underframe and used for adjusting the position of the iris detection device, when the device is used, a worker firstly stands in the station frame and adjusts the height of the iris detection device by pressing a button I or a button II, the rotation direction of a servo motor at the bottom is controlled, so that the position of a movable block is adjusted, then a knob rod is rotated in advance to drive a rack to move upwards through the rotation of a gear, so that the dustproof frame is moved upwards, then the worker aligns glasses to an iris detection body to shade eyes through a shading flexible strip, and therefore quick detection is realized. In the above prior art, although the light-shielding flexible strip is used for shielding eyes, the light-shielding effect may be insufficient under a strong light environment, which affects the accuracy of iris recognition. Disclosure of utility model The utility model aims to provide a well personnel access detection device, which aims to solve the technical problems that although a shading flexible strip is used for shading eyes in the prior art, shading effect is possibly insufficient under a strong light environment and accuracy of iris recognition is affected.
