Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The general system block diagram of fig. 1 is shown in conjunction with fig. 5. The system comprises: equipment detection module, personnel detection module, camera module, display screen module, information prompt module and control chip, wherein, control chip includes first main control unit and the second main control unit that the communication is connected, first main control unit is singlechip STM32F407ZGT6, the second main control unit is singlechip STM32F103ZET 6.

The personnel detection module comprises an IC card and a YMC150-C11 type RFID reader-writer, the RFID reader-writer is connected with a serial port of the first main controller, the IC card is worn on a student body, and personal information of the student is acquired through the IC card and transmitted to the upper computer.

The equipment detection module comprises a radio frequency identification module FM-507 and a radio frequency label, and is connected with the serial port of the first main controller, and the radio frequency label is attached to the experimental equipment. And acquiring the equipment label information through radio frequency label identification.

The camera module is used for recording the shooting site and storing in the SD card.

The display screen module is a ceramic capacitor serial port screen TJC4832T135_011C which is connected with the serial port of the second main controller.

The information prompt module comprises a voice module 6 and a communication module 5, the voice module comprises a voice chip and a loudspeaker in a SYN6288 model, the voice chip is connected with a serial port of the second main controller, the communication module is connected with the serial port of the second main controller, the communication module is shown in a schematic diagram in fig. 3, and the voice chip is connected with the serial port of the second main controller.

The voice module realizes voice broadcasting and reminding, the communication module is used for sending short messages to an administrator, and the content of the short messages is the equipment tag number which is taken away from a laboratory and the file name of a shot photo. The people detection module is connected with STM32F103ZET6, and STM32F103ZET6 is connected with STM32F407ZGT 6.

The equipment detection module is connected with a first main controller STM32F407ZGT6, and detects whether the equipment is taken out of the laboratory through a detection channel.
