The device combines modern information technology, automatic identification technology and safety management system. The identification device automatically generates attendance reports by recording the entry and exit time of construction personnel, making it convenient for managers to conduct attendance management.

[0003] At present, most of the entry and exit identification devices for construction labor workers obtain the fingerprint information of the construction workers through fingerprint scanners to confirm their identities and record the entry and exit times. However, due to the complex environment on the construction site when the construction labor workers work, the workers' fingers are easily stained with dust, oil and moisture, which leads to inaccurate fingerprint recognition, resulting in errors in the entry and exit records of the construction workers, affecting attendance statistics and working hours calculation.

[0034] In this embodiment, at the construction site, in order to facilitate the recording of the entry and exit of construction personnel, a personnel entry and exit identification device is often installed at the construction site, and the fingerprints of the construction personnel are respectively recorded into the two optical fingerprint sensors 416 in the early stage. Due to the poor environment of the construction site, the fingers of the construction personnel are easily contaminated with dirt during the construction process, covering the fingerprints, which makes it inconvenient for the identification device to identify the fingerprint. When the staff needs to enter the construction site, first insert the corresponding finger into the corresponding rubber sleeve 502, wherein, since the rubber sleeve 502 has a certain elasticity and sealing, it can effectively prevent the outflow of cleaning water when the fingerprint is cleaned with water later. After the finger passes through the rubber sleeve 502, one end of the fingerprint surface of the finger is placed on the surface of the pressure-resistant frame 503, and then the fingerprint is facing the outer surface of the spray plate 411, and then the water pump 418 is started to drive the output pipe 419 to draw water to the inside of the water tank 417, and the water source enters the inside of the connecting pipe 406 through the curved pipe 405, wherein, as shown in FIG. Figure 6 As shown, the cross section of the connection between the connecting pipe 406 and the bent pipe 405 is T-shaped, which is to limit the connecting pipe 406 and facilitate its rotation. In addition, the waterproof gasket 407 is made of rubber material, which can effectively prevent water leakage from occurring at the connection between the connecting pipe 406 and the bent pipe 405. After the water source enters the inside of the connecting pipe 406 along the bent pipe 405, it is finally sprayed outward through the spray plate 411 to perform high-pressure spray cleaning on the fingerprint surface of the finger, wherein, as shown in FIG. Fig. 9As shown, the arc plate 409 is directly opposite to the pressure-resistant frame 503, and its purpose is to facilitate the identification of fingerprints. After the fingerprint surface of the finger is cleaned by the spray plate 411, the stepper motor 402 is started to drive the rotating shaft 403 to rotate, and then drive the driving gear 404 to rotate, thereby driving the driven gear 408 to rotate, and the rotation of the driven gear 408 drives the connecting pipe 406 to rotate, so that the arc plate 409 rotates 120° counterclockwise, and then the two fans 414 rotate to the position facing the pressure-resistant frame 503, and at the same time, the two heating wires 4 15 is electrically connected to an external power source to release heat to the outside, and at the same time, the two fans 414 are started through the controller 206, so that the heat released by the heating wire 415 is converted into strong wind to be output to the outside, and the fingerprint surface of the finger is dried with hot air to facilitate the identification of the fingerprint later. When the moisture on the fingerprint surface of the finger is dried, the stepper motor 402 is started again to continue to drive the arc plate 409 to rotate 120° counterclockwise, so that the optical fingerprint sensor 416 rotates to the position facing the anti-pressure frame 503, and the optical fingerprint sensor 416 can be started through the controller 206. Fingerprint sensor 416, wherein the optical fingerprint sensor 416 emits light to the surface of the finger through an LED. When the light shines on the fingerprint, the ridges and valleys of the fingerprint will reflect and absorb the light in different ways. The ridges of the fingerprint will reflect more light, while the valleys will reflect less. The photodetector will capture the reflected light and convert the intensity information of the light into an electronic signal, thereby generating an image of the fingerprint. The obtained fingerprint image will be analyzed by the processing system to extract the characteristic points of the fingerprint. During the fingerprint recognition process, the sensor will compare the fingerprint features currently scanned with the features stored in the database. If the matching degree exceeds the set threshold, the recognition is successful, otherwise it is unsuccessful. The optical fingerprint sensor 416 scans the fingerprint on the finger, scans and recognizes the fingerprint of the person entering and leaving, and cleans and air-dries the fingerprint of the staff, effectively preventing the dirt on the hands of the construction staff from affecting the normal reading of the fingerprint, thereby solving the problem that most of the existing construction labor construction personnel entry and exit recognition devices do not have a fingerprint cleaning function, which easily leads to fingerprint recording errors.

[0035] like Figure 1-Figure 9 As shown, the blocking component 2 includes a forward and reverse motor 201, the outer surface of the forward and reverse motor 201 is fixedly connected to the outer surface of the base plate 1 by screws, the output end of the forward and reverse motor 201 is fixedly connected to a screw rod 202, the two ends of the screw rod 202 are respectively movable to penetrate to the opposite outer sides of the base plate 1, the outer thread sleeve of the screw rod 202 is provided with a guardrail 203, the opposite outer surfaces of the guardrail 203 are respectively slidably connected to the relative inner walls of the base plate 1, a limit frame 204 is fixed near the center of the top of the base plate 1, the interior of the limit frame 204 slides with the outer surface of the guardrail 203, an alarm 205 is arranged on the inner top surface of the limit frame 204, and a controller 206 is arranged on the inner wall of one side of the limit frame 204.

[0036] In this embodiment, when the optical fingerprint sensor 416 does not recognize the fingerprint of the staff member, it means that the fingerprint of the staff member is not included or an outsider has invaded. The optical fingerprint sensor 416 will transmit the signal to the controller 206, and the alarm 205 will be activated through the controller 206 to send out an alarm message to remind the staff that an outsider has invaded. When the optical fingerprint sensor 416 recognizes the fingerprint of the staff member, the signal will be transmitted to the controller 206, and the forward and reverse motors 201 will be activated through the controller 206 to drive the screw rod 202 to rotate, and then drive the guardrail 203 to move to the outside of the limit frame 204 until the guardrail 203 is completely moved out of the limit frame 204. The staff can enter the construction site through the limit frame 204. Through the action of the blocking component 2, the construction site can be effectively prevented from being invaded by outsiders.

[0037] like Figure 1-Figure 10 As shown, two rectangular grooves 3 are provided on the inner wall of the other side of the limit frame 204, and circulation components 5 are arranged inside the two rectangular grooves 3. The two circulation components 5 include mounting frames 501. The outer surfaces of the two mounting frames 501 are respectively fixedly connected to the inner walls of the two rectangular grooves 3. Rubber sleeves 502 are arranged between the opposite inner walls of the two mounting frames 501. The inner bottom surfaces of the two mounting frames 501 are fixedly installed with pressure-resistant frames 503. The bottoms of the two mounting frames 501 are fixed with drainage boxes 504. The outer surfaces of the two drainage boxes 504 are fixedly connected to the inner wall of the limit frame 204. A leakage plate 505 is fixedly connected near the top between the opposite inner walls of the two drainage boxes 504. The outer surfaces of the two drainage boxes 504 are fixedly connected with a conveying pipe near the bottom. 512, cache bins 513 are fixed on the top of the bottom plate 1 near the front surface and the rear surface, the outer surfaces of the two cache bins 513 are fixedly connected with return pipes 511 near the bottom, one ends of the two return pipes 511 are respectively fixed and penetrate into the interiors of the two water tanks 417, the tops of the two cache bins 513 are fixedly connected with hollow tubes 509, the outer surfaces of the two hollow tubes 509 are respectively provided with one-way valves 510, the tops of the two hollow tubes 509 are fixedly connected with purification boxes 506, the bottom ends of the two conveying pipes 512 are respectively fixed and penetrate into the interiors of the two purification boxes 506, leakage plates 507 are fixedly installed between the relative inner walls of the two purification boxes 506 near the top, and leakage boxes 508 are respectively provided between the relative inner walls of the two purification boxes 506 near the bottom.

[0038] In this embodiment, when the water source is sprayed outward through the spray plate 411, the water source will move downward under the action of its own gravity after contacting the fingerprint, enter the interior of the drainage box 504 through the leak plate 505, and finally enter the interior of the purification box 506 through the delivery pipe 512. First, large particles of impurities are retained on the top of the leak plate 507 through the leak plate 507, and small particles of impurities enter the leak box 508 through the leak plate 507 for secondary purification. The leak box 508 contains ion exchange resin, and the tiny impurities in the water are filtered and cleaned through the ion exchange resin. The ion exchange resin has fixed negatively charged groups that can exchange with cations in the water. When water flows through the ion exchange resin, the ions on the surface of the resin will exchange with the ions in the water. By selectively removing specific ions, the water source is purified. The purified water source enters the cache bin 513 through the hollow tube 509. The one-way valve 510 can effectively prevent the water source in the cache bin 513 from flowing back into the purification tank 506. After entering the cache bin 513, the water source will flow back to the water tank 417 along the reflux pipe 511, thereby realizing the recycling of cleaning water.

In the process of the water source spraying outward through the spray plate 411, the water source will move downward under the action of its own gravity after contacting the fingerprint, and enter the interior of the drainage box 504 through the leak plate 505, and finally enter the interior of the purification box 506 through the delivery pipe 512. First, large particles of impurities are retained on the top of the leak plate 507 through the leak plate 507, and small particles of impurities enter the interior of the leak box 508 through the leak plate 507 for secondary purification, wherein the leak box 508 contains The ion exchange resin is used to filter and clean the tiny impurities in the water. The purified water source enters the interior of the buffer chamber 513 through the hollow tube 509. In addition, the one-way valve 510 can effectively prevent the water source in the buffer chamber 513 from flowing back to the interior of the purification box 506. After the water source enters the interior of the buffer chamber 513, it will flow back to the interior of the water tank 417 along the reflux pipe 511, so as to realize the recycling of the cleaning water. When the fingerprint surface of the finger is cleaned by the spray plate 411, the stepper motor 402 is started to drive the rotating shaft 403 to rotate, and then drive the driving gear 404 to rotate, thereby driving the driven gear 408 to rotate, and the rotation of the driven gear 408 drives the connecting pipe 406 to rotate, so that the arc plate 409 rotates counterclockwise by 120°, so that the two fans 414 rotate to the position facing the anti-pressure frame 503, and at the same time, the two heating wires 415 are electrically connected to the external power supply to release heat to the outside, and at the same time, the two fans 414 are started by the controller 206, so that the heat released by the heating wires 415 is converted into strong wind and output to the outside, and the fingerprint surface of the finger is dried by hot air, which is convenient for the later identification of the fingerprint. When the moisture on the fingerprint surface of the finger is dried, the stepper motor 402 is started again to continue to drive the arc plate 409 to rotate counterclockwise by 120°, so that the optical fingerprint sensor 416 rotates to the position facing the anti-pressure frame 503, and the optical fingerprint sensor 416 can be started by the controller 206 to scan and identify the fingerprint.When the optical fingerprint sensor 416 does not recognize the staff member's fingerprint, it means that the staff member's fingerprint is not included or an outsider has invaded. The optical fingerprint sensor 416 will transmit the signal to the controller 206, and the alarm 205 will be activated by the controller 206 to send out an alarm message to remind the staff member that there is an outsider intrusion. When the optical fingerprint sensor 416 recognizes the staff member's fingerprint, the signal is transmitted to the controller 206, and the forward and reverse motors 201 are activated by the controller 206 to drive the screw rod 202 to rotate, and then drive the guardrail 203 to move to the outside of the limit frame 204 until the guardrail 203 is completely moved out of the limit frame 204, and the staff can enter the construction site through the limit frame 204.
