Description
Technical Field
[0001] The present invention relates to the technical field of teaching experimental instruments, and particularly to an intelligent experimental bench and its management system. Background Art
[0002] In the experimental teaching of colleges and universities in China, experimental boxes, as important experimental carriers for professional courses such as circuits, digital logic circuits, and analog electronic technology, have been widely used. The traditional experimental box system mainly relies on students to manually operate to complete the switching and storage of experimental boxes. This method is not only prone to mechanical wear, poor contact, and other problems of experimental boxes during frequent operations, but also has potential problems such as management chaos and low efficiency. With the increase in the number of experimental courses and the continuous expansion of the student scale in colleges and universities, the traditional manual operation mode has been difficult to meet the requirements of modern teaching for efficient and accurate experimental operations.
[0003] To address the above challenges, domestic technicians have begun to explore intelligent improvement solutions for experimental teaching. For example, the disclosed intelligent experimental table and its control system (such as CN210079585) uses a flip structure to achieve the switching of experimental benches, and can achieve the storage and switching of multiple experimental benches to a certain extent. However, this technical solution has obvious deficiencies: on the one hand, in the non-working state of the experimental bench, some experimental benches will still be exposed, vulnerable to dust and other environmental factors; on the other hand, once a single experimental box fails, it is often necessary to pause the entire rotation device for maintenance, further reducing the overall use efficiency of the system. At the same time, most current colleges and universities use experimental boxes for experimental teaching. If the intelligent experimental table of this technology is adopted, all the original experimental box resources will be wasted.
[0004] Based on the limitations of the above existing technologies, developing an intelligent experimental bench and its management system that integrates experimental teaching and experimental box storage has important theoretical significance and practical application value for improving the long-term reliability, management efficiency, and teaching quality of experimental equipment.

Specific implementation manners
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, so that those skilled in the art can better understand the advantages and features of the present invention, and thus more clearly define the protection scope of the present invention. The embodiments described in the present invention are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the protection scope of the present invention.
[0020] As Figure 1 shown, an intelligent test bench includes a test bench and an experimental box rotation device. A display screen 1 and a truth table checker 2 are respectively arranged on the desktop of the test bench. An experimental box lift-out port 6 for lifting the experimental box is also arranged on the desktop of the test bench. The experimental box lift-out port 6 is connected to the internal space of the test bench. A wire drawer 3, a chip drawer 4 and an experimental instrument drawer 5 are respectively arranged on the front side of the test bench. The wire drawer 3, the chip drawer 4 and the experimental instrument drawer 5 are arranged at intervals from top to bottom in sequence. The wire drawer 3, the chip drawer 4 and the experimental instrument drawer 5 are used to store the materials required for the experiment. An experimental box rotation device is also arranged inside the test bench, which is used to store the experimental boxes required for the experiment and switch the experimental boxes to be used by the test bench.
[0021] In this embodiment, the size of the experimental bench can be determined according to actual size requirements. The display screen 1 is used for experimental bench management to assist students in completing experiments. The truth table checker 2 is provided to help students quickly familiarize themselves with the chip characteristics. It can input signals to the chip through a DIP switch and judge the chip output state by the on / off status of the connected LEDs. At the same time, when the student starts the experiment, the truth table detector 2 will be automatically powered on to provide 3.3V, 5V, and GND power supplies for the chips used in teaching, assisting the students to better familiarize themselves with the chips used in the experiment based on the information displayed on the display screen 1 and judge whether they can function properly.
[0022] Among them, the wire drawer 3 is as Figure 3 shown. It contains four grooves of different sizes and a wire detection device. The four different grooves can classify and store wires of different thicknesses, lengths, and can also store special wires such as oscilloscope wires separately for easy access. At the same time, a wire detection device is set. When the switch is turned on, the two ends of the wire are placed against the two ends of the detection device. If the wire conducts normally, the two ends of the detection device are short-circuited, and the buzzer inside the device will make a sound, indicating that the wire can be used normally, which helps to reduce interference from other factors in the laboratory and better realize laboratory teaching. When it is not experimental time or the student has not logged in to the system, the wire drawer 5 will be locked and cannot be opened; after the student logs in to the system, the wire drawer 5 will be automatically unlocked to provide experimental tools for the student.
[0023] Among them, the chip drawer 4 is as Figure 4 shown. It contains multiple grids that can store different chips, and also contains a grid that can store tools such as scissors and tweezers, which is convenient for the reasonable access of chips during the experiment and storage after the experiment. The grid design of the drawer can be determined according to needs. When it is not experimental time or the student has not logged in to the system, the chip drawer 4 will be locked and cannot be opened; after the student logs in to the system, the chip drawer 4 will be automatically unlocked to provide experimental tools for the student.
[0024] Among them, the experimental instrument drawer 5 can store instruments such as oscilloscopes and signal generators. When not in use, they can be stored in the drawer, which is convenient for protecting the equipment and reasonably managing the experimental bench. When it is not experimental time or the student has not logged in to the system, the experimental instrument drawer 5 will be locked and cannot be opened; after the student logs in to the system, the experimental instrument drawer 5 will be automatically unlocked to provide experimental tools for the student.
[0025] Specifically, as Figures 5 - 8As shown in the figure, the experimental box rotation device includes a carrier platform 9, a fixing device 10, a lifting control motor 11, a rotation control motor 12, a lifting gear 13, a chassis 14, a rotation gear 15, a driving gear 16, a lifting control gear 17, a lead screw 18, a rotating carrier plate 19, a driven gear 20, an input gear 21, a rotation gray scale sensor 22, a bracket 23, a lead screw nut 24, a lifting gray scale sensor 25, a rotation control gear 26, a fixed carrier plate 27, and a lifting gear fixing device 28; The chassis 14 is fixedly connected to the bottom of the experimental table. A rotation gear 15 is provided at the middle position on the chassis 14. A rotating carrier plate 19 is provided above the rotation gear 15. A rotation control motor 12 and a bracket 23 are respectively provided on the rotating carrier plate 19. The rotation control motor 12 is fixed on the rotating carrier plate 19 and passes through the rotating carrier plate 19 to be connected to the rotation control gear 26 below it. The rotation control gear 26 meshes with the rotation gear 15; The driving gear 16, the driven gear 20, the input gear 21, and the lead screw nut 24 form a differential assembly. There are four groups of differential assemblies, which are circumferentially spaced apart. The input gear 21 of each group of differential assemblies is located at the bottom. Two driving gears 16 are symmetrically arranged above the input gear 21. The two driving gears 16 mesh with the internal teeth of the input gear 21. The driven gear 20 is arranged above the driving gear 16. The driven gear 20 meshes with the two driving gears 16. The lead screw nut 24 is fixed above the driven gear 20 to realize the intelligent storage and switching of the experimental box; The lead screw nut 24 is sleeved on the lead screw 18. The top of the lead screw 18 is provided with a carrier platform 9; A fixed carrier plate 27 is provided above the bracket 23. The lead screw nut is fixed in the fixed carrier plate 27. A lifting control motor 11 and a fixing device 10 are respectively provided on the fixed carrier plate 27; The fixing device 10 passes through the fixed carrier plate 27 and is connected to the bracket 23; The lifting control motor 12 is fixed on the fixed carrier plate 27 and passes through the fixed carrier plate 27 to be connected to the lifting control gear 17 below it; There are two lifting gear fixing devices 28 on the fixing device 10. They are circular cylinders and are connected to the fixing device 10 through bearings in the middle; The lifting gear 13 is fixed in the middle of three pairs of lifting gear fixing devices 28; The lifting control gear 17 meshes with the lifting gear 13; A rotation gray scale sensor 22 is also provided on the chassis 14, and the rotation gray scale sensor 22 is arranged on one side of the rotation gear 15; A lifting gray scale sensor 25 is provided on the lead screw nut 24; The rotation control motor 12 drives the carrier platform 9 to rotate through the rotation gear 15 and combines with the feedback system of the rotation gray scale sensor 22 to realize the precise positioning of the experimental box; The lifting control motor 11 drives the differential assembly through the lifting gear 13 and the lifting control gear 17 transmission mechanism to control the rotation of the lead screw 18 to adjust the lifting height of the carrying platform 9, and combines with the lifting gray-scale sensor 25 for real-time feedback control to ensure the stable access of the experimental box.
[0026] Specifically, a lifting baffle 7 and a heat dissipation port 8 are respectively provided on the experimental table. The lifting baffle 7 is located inside the experimental table and is arranged above the experimental box rotation device for assisting in controlling the lifting of the carrying platform 9; the heat dissipation port 8 is located at the rear of the experimental table for dissipating heat inside the intelligent test bench.
[0027] In this embodiment, the experimental box can be fixed on the lead screw 18 through the carrying platform 9. The experimental box rotation device designed in this experimental table contains 4 carrying platforms 9 and can store different types of experimental boxes. The storage quantity of the experimental boxes can be 0 to 4, and at most 4 different types of experimental needs can be met, which fully saves the space and management and maintenance costs of the laboratory and improves the use efficiency. At the same time, the number of experimental boxes that the rotation device can accommodate can be expanded as needed. The storage of the experimental boxes can be completed through the control system. When a new experimental box needs to be stored, the control system can lift the empty carrying platform 9 to the experimental box lifting outlet 6. After placing the experimental box and setting the name of the newly stored experimental box in the system, the system can subsequently rotate and lift out the required experimental box to the experimental box lifting outlet 6 according to the name of the experimental box.
[0028] Among them, the experimental box rotation device is as Figure 6As shown, its chassis 14 is fixed at the bottom of the intelligent experimental bench to achieve the storage, collection and rotation of multiple experimental boxes. When it is not the experimental time, all experimental boxes are fixed on the carrier platform 9 and stored inside the intelligent experimental bench. When an experimental box is needed, the system will query the experimental box used in the reserved experiment according to the student ID number logged in by the student, and at the same time determine its position inside the experimental box. After determining the position, the intelligent control system calculates and determines the direction and angle required for the rotation control motor 12 according to the angle required for the rotation of the rotating turntable 19 and the tooth number ratio of the rotation control gear 26 and the rotation gear 15, and controls the rotation control motor 12 to rotate, rotating the carrier platform 9 where the experimental box to be used is located to directly below the experimental box lifting outlet 6. At the same time, the lifting gray-scale sensor 25 on the chassis will detect the number of teeth rotated by the bottom rotation gear 15, calculate the angle rotated by the bottom rotation gear, and feedback it to the system to achieve precise control of the rotation angle and reduce errors. After the rotation gear 15 rotates through the specified angle, the intelligent control system calculates and determines the direction and angle required for the lifting control motor 11 according to the height required for the lifting of the carrier platform 9 and the tooth number ratio of the lifting control gear 17 and the lifting gear 13, and controls the lifting control motor 11 to rotate, driving the rotation of 4 input gears 21. At this time, the driving gear 16 rotates with the input gear 21, driving the driven gear 20 to rotate. The lead screw nut 24 in the driven gear 20 rotates to raise the lead screw 18, pushing 4 carrier platforms 9 to rise simultaneously. Among them, when the other 3 experimental boxes or carrier platforms 9 that do not need to rise are rising, they will be blocked by the lifting baffle 7 in the experimental bench. At this time, due to the resistance, the lead screw 18 under the carrier platform 9 where these 3 experimental boxes are located cannot continue to rise, and the driven gear 20 stops rotating. However, since the rotation gear 15 is still rotating, the input gear 21 drives the driving gear 16 to rotate idly, and the position of the experimental box to be lifted out is not blocked, and the carrier platform 9 where it is located is still driven to rise by the lead screw 18 controlled by the driven gear 20. At the same time, a lifting gray-scale sensor 25 is provided at the junction of the driven gear 20 and the lead screw 18, such as Figure 7As shown in the figure. When the lead screw 18 is controlled by the driven gear 20 to rise, the lifting gray-scale sensor 25 measures and transmits it to the system according to the thread change of the lead screw 18. The system calculates the actual rising height of the carrying platform 9 based on its feedback and compares it with the set value to more accurately control the carrying platform 9 to rise to the expected height. After the experiment is over, the intelligent control system calculates and determines the rotation direction and angle required for the lifting control motor 11 according to the height that the carrying platform 9 needs to descend and the tooth ratio of the lifting control gear 17 and the lifting gear 13, and controls the lifting control motor 11 to rotate, so that the input gear 21 drives the driven gear 20 to rotate through the driving gear 16, and controls the lead screw 18 to drive the four carrying platforms 9 to descend. Since the 3 non-lifted carrying platforms 9 are blocked by the lifting baffle 7 and are at a lower height, they touch the bottom faster than the lifted carrying platform 9. At this time, the lifting gear 13 is still driving the input gear 21 to rotate, and the driving gear 16 idles and does not drive the driven gear 20 to continue rotating, and the 3 carrying platforms 9 stop. When the carrying platform 9 that has risen out of the experiment box outlet also descends to the bottom, the lifting gray-scale sensor 25 will detect that all 4 lead screws 18 have stopped moving. At this time, the lifting control motor 11 stops, and the experiment box is stored up.
[0029] As Figure 9 shown, a management system for an intelligent experimental bench is implemented by using the intelligent experimental bench as described above, and includes an intelligent control system and a safety monitoring system; The intelligent control system includes a host computer, a control module, a display module, a rotation module, a power supply module, and an equipment storage module; the host computer, the control module, the display module, the rotation module, the power supply module, and the equipment storage module can automatically schedule the experimental box according to the experimental course arrangement, and provide experimental guidance information through the display screen 1; the host computer is connected to the control module, the control module is respectively connected to the display module, the rotation module, the power supply module, and the equipment storage module, and the display module, the rotation module, the power supply module, and the equipment storage module are all connected to the experimental equipment; In this embodiment, the control module is used to control the above-mentioned intelligent experimental bench to implement experimental teaching. The host computer and the control module are wirelessly connected; the control module is wired to the rotation module, the power supply module, and the equipment storage module. The experimental equipment includes experimental boxes and tools required for experiments such as wires and chips, and the experimental boxes are stored and fixed on the rotation device.
[0030] Among them, the host computer is a PC, which establishes a network connection with each intelligent experimental bench in the laboratory by using the TCP / TP protocol. Each intelligent experimental bench has its own IP address, and all the experimental benches in the entire laboratory are controlled by one host computer server, realizing intelligent management and better recording of experimental situations.
[0031] The host computer is provided with a control interface, which includes a login interface, an experiment reservation interface, an experiment attendance interface, and a power control interface. Among them, the login interface is used for the laboratory administrator to log in; the experiment reservation interface can complete the reservation of the experiment time and the selection of the experiment project; the experiment attendance interface can record the completion status of the experiment reserved by the user; the power control interface can realize the control of the power supply of each experimental bench.
[0032] The host computer communicates with the control module, sends operation instructions for each module to the control module, and authorizes the control module to control the power on and off of all devices on the intelligent experimental table.
[0033] The control module includes a display screen 1 set on the desktop and a control device set inside the experimental bench. The display screen 1 can be used for experiment management, controlling the rotation device, controlling the material storage module and the power module.
[0034] The control module can receive the information from the host computer and save it. If the logged-in user has no experiment in the current time period, the system will prompt that there is no reservation in this time period and will not enter the experiment system. If the logged-in user has a reserved experiment project in the current time period, the experimental bench will automatically switch to the required experimental bench and enter the corresponding experimental project. At the same time, the control module controls the power module to turn on, and the corresponding experimental box and the truth table checker 2 on the desktop are powered on; the control module controls the material storage module to open all drawers and prompts the materials required for this experiment on the display 1.
[0035] The control module establishes communication with the intelligent tool management cabinet through a serial connection method and indirectly establishes communication with other device modules.
[0036] Among them, the display module is the display screen 1 on the experimental bench surface. Before the experiment, the user can log in to their account through the display screen 1 and start the reserved experiment. During the experiment, the display screen 1 can be used to record experimental data in real time and provide experimental guidance to ensure that the user can accurately complete the experimental steps. In addition, the display screen 1 supports connection with external instruments such as oscilloscopes and signal generators, and can store the experimental waveform data in the system in real time for subsequent analysis or printing. The integrated infrared temperature measurement device on the display screen 1 can monitor the temperature of each area inside the experimental box. Once it detects that the local temperature rises abnormally, the system will immediately issue an alarm and automatically cut off the power supply of the experimental box to prevent the chip from being burned due to overheating. After the alarm is lifted, the user can manually restore the power supply through the display screen 1 to ensure the safety and continuity of the experiment.
[0037] The rotation module is responsible for the automatic scheduling of the experimental box, ensuring that the required experimental box can be accurately lifted out of the experimental table for users to use. After receiving the instructions from the control module, this module drives the rotation control motor 12 and the lifting control motor 11 to perform corresponding operations. When the rotation module completes the preset rotation angle and confirms that the experimental box is in place through the grayscale sensor, the system automatically stops the motor operation and feeds back a signal to the control module. After the experimental box is lifted out, the display screen 1 synchronously displays the component information and experimental steps inside the experimental box to guide users to complete the experimental tasks efficiently.
[0038] The power supply module can be remotely and intelligently controlled by the upper computer or locally managed by the control module for the power supply status of the experimental table. The system can automatically turn on and off the power supply according to the experimental progress, avoiding energy consumption waste caused by long-term standby of equipment and improving the service life of the equipment.
[0039] The equipment storage module includes a wire drawer 3, a chip drawer 4, and an experimental instrument drawer 5, and adopts an intelligent permission management mechanism. Users need to log in and pass the reservation verification first, and then the system will automatically unlock the corresponding drawer, enabling users to access the experimental equipment they need. After the experiment, users need to return and organize the experimental equipment as required, and the system will record the return situation in the experimental scoring criteria to standardize the experimental management.
[0040] The safety monitoring system includes a wire detection device and an infrared temperature measurement device. The wire detection device is placed in the wire drawer 3 and can detect the on-off situation of the wire; the infrared temperature measurement device is integrated in the display screen 1 and can monitor the experimental environment temperature and the experimental chip temperature in real time; if abnormal situations such as wire short circuit overheating and chip abnormal overheating occur, the control system will immediately cut off the power supply and give an alarm on the display screen to ensure the safety of the experiment.
[0041] The experimental work process of the management system of this intelligent experimental table is as follows: 1. The laboratory administrator reserves the experimental time and laboratory for users in the upper computer system.
[0042] 2. The reservation information is sent to the control module, and the system automatically records the experimental arrangement.
[0043] 3. Users enter the laboratory at the reserved time, log in to their accounts on the display screen 1 of the intelligent experimental table, and confirm their identities.
[0044] 4.
