Description

Technical Field

[0001] The present invention relates to the technical field of worker identification technology, and more specifically, to a worker identification device based on a wearable intelligent device. Background Art

[0002] Workers from different units and different jobs are working at the same time, and there are many workers, making it difficult to effectively manage the workers from different units. When managers conduct on-site inspections, they cannot quickly confirm the identity and ability of the workers, cannot track and restrict the violators in time after the inspection, and cannot understand the comprehensive performance of the contractor and its workers in the entire construction process. As a result, the bad violators cannot be effectively controlled, resulting in illegal commands, illegal operations, and violations of labor discipline, which often occur, causing frequent accidents. In order to control this situation, workers often need to use identity recognition devices to identify the workers around them and supervise the operations of the workers around them to prevent the workers from violating regulations. In this process, cameras are needed to record. However, when traditional cameras are worn on the body, although they can move with the workers to different locations to work, the shooting angle of the camera is mostly determined by the direction of the worker's body when shooting. Although the angle of the traditional camera can be adjusted, it will be blocked by the worker's body when adjusting the shooting angle, resulting in a shooting blind spot. The shooting effect is poor when worn, which is not conducive to use.

[0003] In view of this, we propose a worker identity recognition device based on wearable smart devices. Summary of the invention

[0063] The working principle of the present invention is:

[0064] When the staff needs to wear the identity recognition device, his body passes through the middle of the track 1 and then uses the strap 2 to fix the device on his body. Then, the motor 5 is started. The motor 5 drives the rubber wheel 6 to rotate. The rotation of the rubber wheel 6 can rub against the inner wall of the slot 3, so that the sliding block 4 moves along the slot 3 on the track 1. When the sliding block 4 moves, the friction block 18 causes the slider 17 to move to the other side along the direction of the slide slot 16 under the action of the friction force. When the slider 17 moves, it can drive the rack 20 to move. The movement of the rack 20 can drive the gear 21 to rotate. The rotation of the gear 21 can drive the rotating rod 22 to rotate; under the action of the two thread grooves 23 with opposite spiral directions on the rotating rod 22, the moving block 25 on the protective box 27 and the protective cover 28 moves in the opposite direction along the moving groove 24, so that the protective box 27 and the protective cover 28 move relative to each other, thereby exposing the camera 7 inside. Then, when the sliding block 4 moves, the camera 7 can continuously move to record the behavior of the surrounding workers, and transmit the information to an external computer through wireless signals and an external control mechanism, so as to identify the identities of workers in different directions. When the sliding block 4 drives the camera 7 to revolve, one end of the sleeve rod 15 on one side of the camera 7 can slide inside the corrugated groove 10 along the direction of the corrugated groove 10. During the sliding process of the sleeve rod 15, the camera 7 can be driven to automatically swing back and forth up and down through the sliding rod 13, thereby increasing the shooting range of the camera 7.

[0065] When an outside worker enters the work area, the threaded rod 32 can be loosened to make the threaded rod 32 withdraw from the fixed block 31, and then the rotating plate 29 can be rotated to make one end of the block 30 contact one end of the stop ring 9, so that the rotating plate 29 can be laid flat for the outside worker to fill in the identity information on the upper side thereof, and the fingerprint of the outside worker can be collected by the fingerprint collector 34. When the rotating plate 29 is not needed, the rotating plate 29 can be rotated and connected to the fixed block 31 by the threaded rod 32 so that the rotating plate 29 is fixed in front of the worker. The spring A14 is provided to give pressure to one side of the sleeve rod 15 so that the one side of the sleeve rod 15 is always located inside the corrugated groove 10, and the spring B19 is provided to squeeze the pressure of the friction block 18 so that the friction block 18 is always tightly fitted with the outer wall of the track 1, and the spring C26 is provided to make the protection box 27 rise to the highest point under the action of the two moving blocks 25 on the lower side when not in use, so that it can be sleeved on the outside of the camera 7, and under the action of the rotating rod 22 and the threaded groove 23, the protection cover 28 is covered on the upper side of the protection box 27 to protect the camera 7.
