Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. It is to be understood that the specific embodiments are merely illustrative of the novel forms of the invention, and not restrictive. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1 shows the utility model discloses a people's face fingerprint entrance guard management system's structure that embodiment provided, people's face fingerprint entrance guard management system has included people's face fingerprint entrance guard all-in-one, two magnetic locks, go out key switch, relay and APP customer end. Wherein two magnetic lock simultaneously with people's face fingerprint entrance guard all-in-one, relay and the key switch wired connection that goes out, and APP customer end simultaneously with people's face fingerprint entrance guard all-in-one and relay communication connection. Therefore, the user can directly open the door through the all-in-one machine and the key switch, the door can be opened remotely through the APP client, and the all-in-one machine can be communicated with the APP client remotely.

Fig. 1 a human face fingerprint access control system, as shown in fig. 2, includes a human face recognition module, a touch key 6, a filmless optical fingerprint collector 8 and a speaker 7. The face recognition module is composed of an RGBA camera 2, an infrared camera 3, an infrared distance measurement 4 and a liquid crystal screen 1 and is positioned on the right side of the all-in-one machine. The two cameras are wide-angle cameras, wherein the light source of the RGBA camera 2 is a visible light source, and the light sensing of the infrared camera 3 is infrared rays, so that camera images with longer distance and higher quality can be acquired. The configuration of the two cameras can effectively acquire continuous and high-quality face images. The image captured by the camera is displayed on the liquid crystal screen 1 in real time. Two sides of the two cameras are respectively provided with an infrared distance measurement device, when a target to be detected enters a detection area, a detected face image is captured, a characteristic value is extracted and compared with data in a face database, a comparison result is displayed on the liquid crystal screen 1, and prompts such as 'welcome', 'recognition failure' and the like are broadcasted through a loudspeaker 7 in a voice mode. And if the identification is successful, the door is opened by configuring the high and low levels of the GPIO connected with the double-door magnetic lock. Meanwhile, the all-in-one machine can judge the opening and closing states of the entrance guard by reading the level of the GPIO port, and if the entrance guard is detected not to be closed for a long time, an alarm prompt that the entrance guard is not closed is sent out through the loudspeaker 7.

The touch key 6 is positioned above the left side of the face fingerprint access control all-in-one machine, and the total number of the touch keys is 12, namely an OK key, an ESC key and number keys from 0 to 9. When the number key is clicked, the pressed number is displayed on the liquid crystal screen 1, if the number input by the ESC key is mistakenly input, the number input by the previous position can be deleted, and after the input is finished, the OK key is clicked to call the house owner of the inputted house number. When a house owner receives a video request through the APP client, the house owner can select to directly and remotely open a door or answer a video call. After the video call is answered, the homeowner can see the picture captured by the RGBA camera 2, and the picture and the sound of the homeowner are transmitted to the caller through the liquid crystal screen 1 and the loudspeaker 7. The maximum length of the key input data is 4 bits, and if the maximum length exceeds 4 bits, the value of the key cannot be read even if the key is pressed. If the key input data is not bound by the OK key but has not changed within a certain time, the input data will be automatically cleared.

The filmless optical fingerprint collector 8 is positioned at the center of the horizontal direction below the face fingerprint access control all-in-one machine, and the two sides are provided with the loudspeaker 7. By pressing the fingerprint collector, the fingerprint characteristics can be rapidly acquired and compared with the data in the database, the comparison result is displayed on the liquid crystal screen 1, and prompts such as 'welcome', 'please press the finger again' are broadcasted through the loudspeaker 7. The back of the face fingerprint door control all-in-one machine is also provided with an anti-disassembly alarm and a backup power supply. When the power is on, the all-in-one machine can be automatically charged so as to ensure that the all-in-one machine can still work for 3 to 5 hours after power failure, and an alarm prompt can be given if the all-in-one machine is tried to be dismounted under the power-on condition.

The specific working process of the face fingerprint access control system comprises the following steps:

1) a user registers a face or a fingerprint on the face and fingerprint access control all-in-one machine.

2) When entering the door, the user with the registered face or fingerprint can directly open the door through face recognition or fingerprint comparison.

3) When entering the door, the user without registering the face and the fingerprint can input the house number through the all-in-one machine and call the house owner.

4) The house owner who receives the video request can directly remotely open the door through the APP client, can also receive the video call, and remotely open the door after confirming the identity of the requester.

5) When going out, no matter whether have registration people's face and fingerprint, all can open the door through pressing the key switch that goes out.
