[0030] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1 As shown, the intelligent experimental table provided by the present invention is used in laboratories of various universities to conduct electrical experiments. It includes a desktop 1 and a cabinet 2 arranged under the desktop 1 for supporting the desktop. The desktop 1 is provided with an opening 3, which is connected to the inner space of the cabinet 2. An intelligent flip experiment device 4 is arranged in the opening 3 and the inner space of the cabinet 2. The intelligent flip experiment device 4 includes a rotating shaft 5 passing through the opening 3 and at least two experimental circuit panels 6 fixed on the rotating shaft 5 and capable of flipping with the rotating shaft 5.

[0032] The table top 1 is a plate-like structure, and its size is determined according to needs.

[0033] The desk cabinet 2 is a box-shaped structure, and two can be provided, one on each side of the left and right sides.

[0034] like Figure 2 , 3 As shown, the rotating shaft 5 is horizontally arranged on the opening 3, one end of which is connected to the cabinet 2 through a flange coupling 17, and the other end is connected to the motor 7 through a coupling 19, and is driven to rotate by the motor 7, and the motor 7 is fixed to the cabinet 2 through a motor frame 18. In order to prevent the power line of the motor 7 from being drawn in during the rotation of the motor 7, a rotating conductive slip ring 20 is arranged between the motor 7 and the rotating shaft 5.

[0035] The experimental circuit panel 6 is fixed on the rotating shaft 5 by means of a fixing frame 8 and a tray frame 16. The fixing frame 8 can be in the form of a cross, which is convenient and practical; the tray frame 16 is a plate-like structure, which is convenient for holding the experimental circuit panel. Two, three or four experimental circuit panels can be provided to meet the needs of more than two different types of experiments, fully saving the limited space of the laboratory and improving the utilization efficiency. The angle between two adjacent experimental circuit panels 6 can be 90°, 120° or 180°, but is not limited thereto, and the setting angle can be determined according to actual needs. In addition, a liquid crystal display screen 9 is provided on the back of each experimental circuit panel 6 for displaying the experimental content of the next experimental circuit panel, which is convenient for users to complete experimental operations and improve efficiency. Figure 3 It should be noted that the number of liquid crystal display screens 9 should be the same as the number of experimental circuit panels 6. The experimental circuit panel can be directly controlled to rotate by the control system to achieve intelligent control.

[0036] like Figure 1As shown, a detection area 10 is provided on the desktop 1, in which auxiliary experimental instruments with RFID tags are placed, and a desktop sensor is provided below the detection area, which cooperates with the RFID tag to sense whether the auxiliary experimental instruments are displaced. For users who have made reservations, the main control module issues usage permissions, and the auxiliary experimental instruments can be moved for use; for users who have not made reservations, the mobile auxiliary experimental instruments will issue an alarm.

[0037] The lower part of the table cabinet 2 is provided with an intelligent tool management cabinet 13 for storing experimental tools. The intelligent tool management cabinet 13 is controlled by a control system, such as Figure 4 For users who have made an appointment, the main control module directly controls the cabinet door to open and use the experimental tools; for users who have not made an appointment or are not at the scheduled time, the cabinet door cannot be opened and the experimental tools cannot be used.

[0038] A flip cover 14 is provided above the intelligent flip experimenter 4, and a camera device for automatically capturing the user's facial image is provided on the flip cover 14. The camera device is a webcam, which can capture the user's facial image twice and upload it to the server for backup, thereby completing the intelligent attendance. It should be noted that the two capture times are: after the user selects the specific experimental circuit board of the intelligent flip experimenter, the camera device will automatically capture the user's facial image for the first time; after the experiment is over, the user exits the system, and the camera device will capture the user's facial image for the second time.

[0039] The desktop 1 is also provided with an intelligent power socket 15 for supplying power to the desktop auxiliary experimental instruments. The intelligent power socket 15 can be controlled to take on and off power through a control system.

[0040] like Figure 6 As shown, the control system of the present invention is used to control the above-mentioned intelligent experimental table, and the control system includes a host computer, a main control module, a motor flip module, a desktop instrument management module, a power module, a tool storage module, an image acquisition module and an experimental instrument. The host computer is wirelessly connected to the main control module and the image acquisition module respectively; the main control module is wired or wirelessly connected to the motor flip module, the desktop instrument management module, the tool storage module and the power module respectively. The experimental instrument includes at least two experimental circuit panels, auxiliary experimental instruments and tools in the intelligent tool management cabinet; at least two experimental circuit panels are connected to the motor flip module; the auxiliary experimental instrument is connected to the desktop instrument management module; the tools in the intelligent tool management cabinet are connected to the tool storage module.

[0041] The host computer is a PC or mobile terminal, which uses TCP / TP protocol to establish a network connection with each intelligent laboratory table in the laboratory. Each intelligent laboratory table has its own IP address. All intelligent laboratory tables in the entire laboratory are controlled by a host computer server, realizing intelligent management. The network includes a local area network, a wide area network, the Internet or other networks.

[0042] The host computer is equipped with a control interface, which includes a login interface, an experiment selection interface, an experiment reservation interface, and a power control interface. The login interface is used by the administrator to log in and complete the setting of attendance and control parameters; the experiment selection interface is used to select the corresponding experimental circuit panel in the flip experimenter; the experiment reservation interface is used by the user to reserve the experiment time and issue a reservation card; the power control interface is used to remotely control the switches and power off of each device on the smart experiment table.

[0043] The host computer communicates with the main control module, sends user identity information, operation instructions of each module, and authorizes the main control module to control the power on and off of all devices on the smart laboratory table.

[0044] The host computer receives the data transmitted by the image acquisition module and records the data to complete the attendance management.

[0045] The main control module includes a main control electronic touch screen 11 arranged on the desktop and a control unit 12 arranged in the desk cabinet. The main control electronic touch screen 11 can store the reservation user information and automatically identify it, and is used to select which operation to perform; the control unit can directly control the motor flip module, the desktop instrument management module and the tool storage module to perform related operations, and directly control the power supply of the desktop.

[0046] The main control module receives the user identity information transmitted by the host computer and saves and identifies it. If it is confirmed that the user is a scheduled user, he can directly enter the experimental system. The relevant content of the experimental system will be displayed on the main control electronic touch screen 11. The user makes corresponding choices according to his own experimental course and completes the experiment. Non-scheduled users or non-scheduled time cannot enter the experimental system after swiping the card. Explain how to use the main control electronic touch screen 11, such as Figure 5 As shown, the user confirms his identity through the card swiping area, and after the identity is confirmed, he enters the experimental system. Use the number buttons on the main control electronic touch screen to select the experimental circuit panel to be selected. For example, the number 1 button corresponds to the type A experimental circuit panel; the number 2 button corresponds to the type B experimental circuit panel. Use the number buttons on the main control electronic touch screen to select whether to open the door of the intelligent tool management cabinet. The button method is the same as above. At the same time, the user swipes the card to choose to pause the experiment, continue the experiment, or exit the system. After exiting, the intelligent flip experimenter, power socket, intelligent tool management cabinet, and image acquisition device will be automatically powered off.

[0047] The electronic touch screen is installed at the lower right side of the desktop, using embedded installation technology to fit the desktop perfectly, saving desktop space and catering to the aesthetic tastes of younger users.

[0048] The main control module establishes communication with the intelligent tool management cabinet through a serial port connection, and indirectly establishes communication with other device modules.

[0049] The motor flip module is used to control the flipping of the experimental circuit panel and flip the experimental circuit panel to a horizontal position for experiment. The specific operation method is that after receiving the instruction from the main control module, the motor flip module drives the motor to rotate, drives the shaft to rotate, and the shaft drives the experimental circuit panel to rotate. After the selected experimental circuit panel is rotated to a horizontal position, it stops rotating and feeds back a successful execution signal to the main control module. At the same time, the corresponding LCD screen displays the instructions for the experimental course. According to the instructions, the experimental operation is carried out efficiently and conveniently.

[0050] The desktop instrument management module includes a desktop sensor, which is used to sense whether the auxiliary experimental instruments with RFID tags placed in the desktop detection area have been moved. The scheduled users can move the auxiliary experimental instruments in the detection area and use them normally through the authorization of the main control module; the non-scheduled users cannot move the auxiliary experimental instruments in the detection area without authorization from the main control module, and the moving desktop will alarm.

[0051] The tool storage module is used to control the switch of the cabinet lock of the intelligent tool management cabinet. It is directly controlled by the main control module through the serial port. The main control module directly issues a door opening command. After the corresponding cabinet door is opened, it feeds back an execution success signal to the main control module.

[0052] The image acquisition module is used to collect facial image data at the beginning and end of the experiment for attendance management. That is, after the authorized user swipes the card to enter the experimental system, the camera automatically captures the user's facial image and directly uploads the image data to the host computer to complete the first step of attendance. After the experiment is completed, the card is swiped to exit the system, and the camera captures the user's facial image again, and uploads the image data to the host computer again to complete the second step of attendance. The teacher can directly view the attendance data on the host computer for easy management. The image acquisition module can directly access the network through the RJ45 interface to interact with the host computer for data. As long as the corresponding capture effect can be achieved, other camera devices can be selected.

[0053] The power module, including the power socket 15, can be powered by the intelligent control switch of the host computer, can be powered by the intelligent control switch of the main control module, or can be powered directly by the reserved user swiping a card.

[0054] There are two switching power supplies in the table cabinet 2. One is in the normally open state and directly powers the main control module. The other is in the control state and powers the intelligent flip experimenter, power socket, and network camera, and is converted into 12V output to power the intelligent tool management cabinet.

[0055] The workflow of the present invention is:

[0056] 1. The user makes an appointment for the experiment time on the host computer and selects a specific smart experiment table;

[0057] 2. After the reservation is successful, the reservation card will be issued and the reservation information will be transmitted to the main control module;

[0058] 3. The user swipes the appointment card to enter the laboratory and scans the code on the electronic touch screen to confirm the identity;

[0059] 4. The main control module performs identity authentication. After successful authentication, it directly enters the experimental system, selects the corresponding experimental circuit panel through the buttons on the main control electronic touch screen, rotates it to a horizontal position, and starts the experiment according to the corresponding experimental instructions displayed on the corresponding LCD screen; in this step, the network camera will capture the facial image of the person and transmit it to the host computer;

[0060] 5. During the experiment, you can choose to use the auxiliary experimental instruments in the testing area, or you can choose to use the tools in the intelligent tool management cabinet;

[0061] 6. After the experiment is over, swipe the card to exit the experimental system, and the webcam will capture the facial image for the second time.

[0062] The intelligent laboratory table and control system of the present invention are not limited to the above-mentioned specific implementation modes. Those skilled in the art may derive other implementation modes based on the technical solution of the present invention, which also fall within the technical innovation scope of the present invention.
