Abstract
The utility model discloses a semi-open access control system based on two-dimensional code, including setting up controller, relay, the electric control lock on the door and being used for showing the display screen of two-dimensional code, the controller is connected with the control circuit electricity of relay, the working circuit of relay is connected with the circuit electricity in the electric control lock, the controller can mobile terminal sweep the sign indicating number information and judge whether open the door. This access control system uses in the classroom of school, and the student can open the door and realize the attendance automatically through the two-dimensional code on the scanning display screen.
Description
Technical Field
The utility model relates to an entrance guard's field especially relates to a semi-open access control system based on two-dimensional code.
Background
In the university, classroom doors are often locked through a lock chain and are uniformly managed by security guards, so that the doors need to be opened by the security guards every time of class, inconvenience is brought to a greater or lesser extent, and if the security guards forget to open the doors, class attendance is possibly influenced. In some schools, security guards can uniformly open the doors in the morning and uniformly lock the doors at night, and in such a way, when some classrooms do not need to go to school, the doors are also opened, so that property loss can be caused.
And, in present university the inside, in order to guarantee that the student can be on schedule class, most mr all can carry out the attendance. At present, attendance is mostly checked by roll calling, and more time is needed for a classroom with more people.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a semi-open access control system based on two-dimensional code, student or mr can open the door through the two-dimensional code to before opening the door, the controller can judge whether this student or mr class in this classroom.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a semi-open access control system based on two-dimensional code, is including setting up controller, relay, the electric control lock on the door and being used for showing the display screen of two-dimensional code, the controller is connected with the control circuit electricity of relay, the working circuit of relay is connected with the circuit electricity in the electric control lock, the controller can mobile terminal sweep the sign indicating number information and judge whether open the door.
Preferably, the controller is connected with the controller electricity and is set up the WIFI module on the door, the controller can communicate with the cloud server through the WIFI module, the controller can send the code information of sweeping to the cloud server after producing the code information of sweeping, the cloud server can be according to sweep the code information and judge whether open the door.
Compared with the prior art, the utility model discloses a following effect has:
this access control system adopts the two-dimensional code as the identification mode, and the user only need sweep can judge whether unblank, easy operation, and is convenient, can realize the function of attendance simultaneously.
Drawings
Fig. 1 is a schematic diagram of a preferred embodiment according to the present invention.
Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.
The utility model provides a semi-open access control system based on believe two-dimensional code a little, includes controller 1, relay 2, electric control lock 3 and sets up display screen 4 on the door, controller 1, relay 2, electric control lock 3 and display screen 4 all set up on the door, the control circuit and the controller 1 of relay 2 are connected, the working circuit and the circuit electricity of electric control lock 3 of relay 2 are connected, and the working circuit of relay 2 is supplied power by external power source, and after controller 1 exports control signal to the control circuit of relay 2, the working circuit switch-on of relay 2, and then realizes the control to electric control lock 3. The display screen 4 is used for displaying two-dimensional codes and other information, and unlocking can be achieved by scanning the two-dimensional codes on the display screen 4 through mobile internet devices such as a mobile phone. The controller 1 adopts STM32 series single-chip microcomputer, the model of relay 2 is HK23F _ DC5V _ SHG, the model of electric control lock 3 is MY-I-F006DKS1, the model of display screen 4 is Spin _ HY 2.0.
The access control system further comprises a WIFI module 5 electrically connected with the controller 1, the controller 1 can communicate with the cloud server through the WIFI module 5, after the WeChat of the mobile terminal scans the two-dimensional code, the controller 1 can send code scanning information to the cloud server, the code scanning information comprises a WeChat account, the cloud server can acquire student information corresponding to the WeChat account according to the WeChat account, the cloud server judges whether the student is in class in the classroom at the time according to the student information, if so, the cloud server sends an unlocking instruction to the controller 1, the working circuit of the controller control relay 2 is switched on to realize unlocking, and whether the unlocking is displayed on the display screen 4. Of course, if the door has been opened and the student is in the classroom, information about the student in the classroom is displayed on the display screen 4 to remind the student to enter the classroom. And, if this student is in class in this classroom in this period of time, the high in the clouds server can take notes in order to carry out the attendance to can send attendance information to mr's mobile terminal, can judge in the high in the clouds server and sweep that the code user is student or mr. The model of the WIFI module 5 is ESP 8266.
The access control system also comprises a power supply 6, wherein the power supply can be provided by commercial power, and a storage battery and the like can also be adopted.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
