Description

Technical Field

[0001] The utility model relates to the field of dust prevention of attendance machines, in particular to a dust prevention attendance machine for construction sites. Background Art

[0002] The attendance machine is a device that authenticates identity based on fingerprints. Light is shone on the glass surface with fingerprints pressed on it, and the reflected light is obtained by the CCD. The amount of reflected light depends on the depth of the ridges and valleys of the fingerprints pressed on the glass surface and the oil and moisture between the skin and the glass. After the light passes through the glass and hits the valley, it is totally reflected at the interface between the glass and the air and reflected to the CCD. The light directed to the ridges is not totally reflected, but is absorbed by the contact surface between the ridges and the glass or diffusely reflected to other places, thus forming an image of the fingerprint on the CCD.

[0003] On construction sites, construction may cause dust to escape. When dust accumulates on the glass surface of the fingerprint module, when personnel perform fingerprint recognition, the shadow created by the accumulated dust will be recognized together, resulting in recognition errors.

[0020] See also Figure 1 to Figure 4 In an embodiment of the utility model, a dustproof attendance machine for a construction site includes a split gate machine 1, and a No. 1 column 2 and a No. 2 column 3 are fixedly installed on the top of the two parts of the gate machine 1 respectively. A groove 4 is opened on the inclined surface of the bottom end of the opening of the No. 1 column 2, and a fingerprint module 8 is installed inside the No. 1 column 2 below the groove 4; a dustproof component is installed inside the No. 1 column 2, and the dustproof component includes a driving unit, a reset unit and a dustproof cloth 13; one end of the dustproof cloth 13 is connected to the driving unit, and the other end of the dustproof cloth 13 is connected to the reset unit; a slide groove is opened inside the No. 1 column 2 at the middle position of the groove 4, and the dustproof cloth 13 is located in the middle position of the slide groove.

[0021] In this embodiment: when the staff enters the construction site, they move between the two parts of the gate 1. At this time, the infrared rays are blocked, and the controller controls the driving unit to roll up the dustproof cloth 13. The rolled dustproof cloth 13 applies tension to the reset mechanism until the dustproof cloth 13 is completely misaligned with the groove 4. At this time, the staff can put the finger with the recorded fingerprint through the groove 4 to contact the fingerprint module 8. After the fingerprint module 8 completes the fingerprint recognition, it sends an electrical signal to the controller, and the controller controls the gate part of the gate 1 to open, so that the staff can enter the construction site through the gate 1;

[0022] After that, the personnel no longer block the infrared rays. At this time, the controller controls the driving unit to unwind the dustproof cloth 13. The dustproof cloth 13 is reset under the drive of the reset mechanism, and the fingerprint module 8 is blocked again to prevent dust from accumulating on the fingerprint module 8.

[0023] Please refer to Figure 3 and Figure 4 The driving unit includes a driving motor 9 installed inside the No. 1 column 2, the output end of the driving motor 9 is connected to a driving gear 10, the outer periphery of the driving gear 10 is meshed with a passive gear 11, one end of the passive gear 11 is connected to a winding roller 17 through a shaft; one end of the dustproof cloth 13 is fixedly connected to the outer periphery of the winding roller 17.

[0024] In this embodiment: when the personnel walks between the first column 2 and the second column 3, since the infrared rays are blocked, the controller controls the driving motor 9 to rotate in the forward direction, the driving motor 9 drives the driving gear 10 to rotate, and the driving gear 10 drives the driven gear 11 to rotate, and at this time the driving gear 10 and the driven gear 11 are in the opposite rotation state;

[0025] The passive gear 11 drives the reel 17 to reel the dustproof cloth 13 .

[0026] Please refer to Figure 3 and Figure 4 The reset unit includes a fixed plate 16 formed at one end of the slide slot, and a spring 15 is fixedly connected to the end of the fixed plate 16 close to the slide slot, and the other end of the spring 15 is connected to a slider 14 slidably connected to the slide slot; a connecting shaft 20 is formed between the two sliders 14, and a circular sleeve 19 is sleeved on the outer wall of the connecting shaft 20, and the other end of the dustproof cloth 13 is fixedly connected to the circular sleeve 19.

At this time, the slider 14 slides in the slide groove, and the spring 15 is stretched until the dustproof cloth 13, the round sleeve 19 and the connecting shaft 20 are completely misaligned with the groove 4;

[0028] After the fingerprint verification is completed, the controller controls the driving mechanism to run in the reverse direction, and the spring 15 is reset, the spring 15 pulls the slider 14 to reset, and the slider 14 pulls the round sleeve 19 and the connecting shaft 20 to reset to the initial position.

[0029] Please refer to Figure 3 The interior of the No. 1 column 2 is rotatably connected with a guide roller 12, both ends of the guide roller 12 are rotatably connected to the inner wall of the slide groove, and the bottom of the outer wall of the dustproof cloth 13 passes through the outer periphery of the guide roller 12 and is connected to the reset unit; the guide roller 12 is used to provide support for the dustproof cloth 13.

[0030] In this embodiment, during the process of winding and unwinding, the guide roller 12 can support the dustproof cloth 13 .

[0031] Please refer to Figure 1 and Figure 2A connection hole 5 is provided on the upper part of the open vertical surfaces of the No. 1 column 2 and the No. 2 column 3.

[0032] In this embodiment: when a person moves between the first column 2 and the second column 3, the infrared rays emitted by the infrared transmitter 7 are blocked, and the infrared receiver 6 cannot receive the infrared rays. The infrared receiver 6 sends an electrical signal to the controller, and the controller controls the driving mechanism to operate;

[0033] When the attendance verification is completed, the personnel leave, and the infrared rays emitted by the infrared transmitter 7 are received by the infrared receiver 6 again. At this time, the infrared receiver 6 sends an electrical signal to the controller, and the controller controls the driving mechanism to run in reverse.

[0034] Please refer to Figure 1 and Figure 3 The interior of the No. 1 column 2 is provided with an installation groove for accommodating the drive motor 9, the driving gear 10, the driven gear 11 and the winding roller 17, and the drive motor 9 is fixedly connected to the inner wall of the installation groove through the installation groove.
