The position number plate 7 made of transparent glass is fixedly arranged right in front of the mobile phone storage boxes 8 through an adhesive, three-digit fixed numbers are engraved in the center of the position number plate 7, the position numbers of the 10 mobile phone storage boxes 8 of the first layer row box 4 are respectively 101, 102, 103, 104, 105, 106, 107, 108, 109 and 110 from left to right, the position numbers of the 10 mobile phone storage boxes 8 of the second layer row box 5 are respectively 111, 112, 113, 114, 115, 116, 117, 118, 119 and 120 from left to right, and the position numbers of the 10 mobile phone storage boxes 8 of the third layer row box 6 are respectively 121, 122, 123, 124, 125, 126, 127, 128, 129 and 130 from left to right. The MCU circuit 14 is connected with the upper computer 13, the infrared pair tube circuit 12 (such as IR333 and PT333 infrared pair tubes) is connected with the display circuit 15 through the MCU circuit 14, the MCU circuit 14 is connected with the card reader circuit 17, and the MCU circuit 14 is also connected with the buzzer circuit 16. The card reader circuit 17 is fixedly arranged on the front and back surfaces of the card reading sensing area 3, and the MCU circuit 14 is fixedly connected with the liquid crystal display screen 1. The infrared pair tube circuit 12, the MCU circuit 14, the display circuit 15, the buzzer circuit 16 and the card reader circuit 17 are all conventional circuits, and the circuits formed by the connection therebetween also belong to conventional circuits.

The working principle of the invention is as follows: the main power switch of the mobile phone storage attendance cabinet for the classroom is closed 10 minutes before the classroom is in class, power is supplied to the mobile phone storage attendance cabinet for the classroom, and the left and right cabinet doors of the cabinet body 2 are opened.

The student firstly puts his own student card in the card reading sensing area 3, the card reader circuit 17 reads the student information in the student card, then sends the student information to the MCU circuit 14 and stores it, then the student puts his own mobile phone into the mobile phone storage box 8, the LED tube in the infrared pair tube circuit 12 on the mobile phone storage box 8 lights up, the position number plate 7 is lighted up, at this time, the infrared pair tube circuit 12 outputs a high level to the MCU circuit 14, that is, the MCU circuit 14 detects a rising edge, after program operation in the MCU circuit 14, the student information is uploaded to a teaching management system platform in the upper computer 13, meanwhile, the MCU circuit 14 outputs a high level to the buzzer circuit 16, the buzzer circuit 16 gives out a 'dropping' sound to indicate that the student is successful in card swiping attendance, at this time, the MCU circuit 14 also outputs the total number of the stored mobile phones to the display circuit 15, and the display circuit 15 drives the liquid crystal display screen 1 to display the total number of the stored mobile phones in the cabinet 2. In this process, the program in the MCU circuit 14 increases the total number of handset deposits by one 1 for each handset deposit.

In the process of storing the mobile phone, if the student only stores the mobile phone without swiping the student card (i.e. reading the student information), or only swipes the student card without storing the mobile phone (i.e. detecting a rising edge), the student information will not be uploaded to the teaching management system platform in the upper computer 13 after program operation in the MCU circuit 14. At this time, the MCU circuit 14 does not output a high level to the buzzer circuit 16, and the buzzer circuit 16 does not emit a "drop" sound, indicating that the student is unsuccessful in checking the attendance by swiping the card.

After the student has finished storing the mobile phone in the mobile phone storage box 8, if the student takes the mobile phone out of the mobile phone storage box 8 after the mobile phone is stored, for example, during a 10-minute rest period between the first class and the second class, a falling edge is generated, and the program in the MCU circuit 14 performs software timing for 8 minutes. If the time of 8 minutes is up, the student does not put the mobile phone back into the mobile phone storage box 8, the MCU circuit 14 outputs a high level to the buzzer circuit 16, the buzzer circuit 16 continuously gives out a 'dropping' sound, and the student is forced to store the mobile phone in the mobile phone storage box 8 again.

After class, students take out the mobile phones, close the left and right doors of the cabinet body 2, and disconnect the main power switch of the mobile phone storage attendance cabinet in the classroom. Waiting for attendance of the next class student.

The student information (such as name, school number, etc.) in the student card is read with the NFC handset, and the NFC handset is set to a card emulation mode. At this moment, the NFC mobile phone can replace the student card to punch the card in the card reading induction zone (3).

Fig. 7 shows a specific circuit of the infrared pair transistor circuit 12 on the cellular phone storage case 8 of position number 101 in the first-tier case 4. When no mobile phone is stored in the mobile phone storage box 8, infrared light emitted by the D1 can shine on the T1, the T1 is conducted, and the output end outputs a low level to the PB0 end of the STM32F103V8T 6. Before class, when students store mobile phones in the mobile phone storage box 8, the mobile phones shield infrared light emitted by D1, the T1 is not conducted, the output end outputs a high level (namely, a rising edge is generated) to the PB0 end of the STM32F103V8T6, meanwhile, the T2 is driven to be conducted, the LED1 diode emits light, and the position number plate 7 is lightened. After class, when the mobile phone is taken out from the mobile phone storage box 8, the T1 is turned on because the infrared light emitted by the D1 is not shielded, the output end outputs a low level (namely, a falling edge is generated) to the PB0 end of the STM32F103V8T6, meanwhile, the T2 is turned off, the LED1 diode is not lighted, and the position number plate 7 is not lighted. The circuit structure and the operation principle of the infrared pair transistor circuit 12 on the handset storage box 8 having the position numbers 102, 103, 104, 105, 106, 107, 108, 109 and 110 in the remaining first tier case 4 are the same.

The screen brightness is changed by adjusting the potential of the 3 rd pin of the LCD12864 through a potentiometer RP1, the 15 th pin of the LCD12864 is directly connected with + VCC in a hardware mode, and the parallel mode is selected. After STM32F103V8T6 receives the total number of the mobile phone deposits in the three-layer row box, the PE8, PE9, PE10, PE11, PE12, PE13, PE14 and PE15 ends of STM32F103V8T6 are sent to LCD12864 to be displayed. Meanwhile, the STM32F103V8T6 uploads the mobile phone storage condition and card-swiping attendance condition of each student in the whole class of each class to a teaching management system platform in the upper computer 12 through PA9 and PA10 ends in time.

The PB12, PB13, PB14, PB15 and PC7 ends of the STM32F103V8T6 in FIG. 9 are connected with the SDE, D5, D7, D6 and/RST ends of the RC522 respectively. The communication between the RC522 and the STM32F103V8T6 in the card reader circuit 17 adopts an SPI mode, the EA end of the RC522 is connected with high level, and the I of the RC522 is connected with high level²The hardware of the C end is connected with low level, and the card reader circuit 17 adopts a card reader circuit 17 module sold in the market. The PE1 end of the STM32F103V8T6 is connected with the buzzer circuit 16. When the PE1 end of the STM32F103V8T6 outputs a low level, the triode T3 is conducted, and the Buzzer Buzzer makes a 'drop' sound. When a high level is output from the PE1 end of the STM32F103V8T6, the triode T3 is not conducted, and the Buzzer Buzzer does not emit a 'drop' sound.

Therefore, the mobile phone storage box 8 and the card reader circuit 17 are adopted, and the mobile phone storage condition and the card swiping condition of each student in the whole class are monitored.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
