[0002] Montessori Cylinder Blocks, a classic Montessori sensory teaching aid, consists of a set of wooden cylinders and corresponding socket plates, typically containing combinations of cylinders with varying heights or diameters. The original design of this aid was to train young children's visual discrimination abilities and three-finger pinching coordination—children must observe the differences in cylinder size and accurately grasp and match them to the corresponding sockets. Educational theory has proven that repeated use of this aid significantly improves children's spatial perception, concentration, and error control, making it a core training tool in educational institutions worldwide.

[0003] The existing Montessori cylindrical socket teaching aid has a feedback problem: the system cannot provide an immediate confirmation signal when a child inserts the cylinder correctly or incorrectly. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the Monte Carlo socket cylinder cannot provide an instant confirmation signal. In view of the shortcomings of the prior art, a Monte Carlo socket cylinder is provided.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The device includes a socket body, insertion holes on the socket body, and cylinders corresponding to the number of insertion holes. Its features include: a data acquisition module comprising an analog-to-digital converter, a control unit, a Flash memory, a DC power supply, and an analog multiplexer; each cylinder has a unique identification resistor inside; each cylinder has an electrical contact socket connected to the identification resistor; and each insertion hole has a concentric electrode for insertion into the electrical contact socket. One contact of the concentric electrode is connected to the analog input pin of the analog multiplexer, and the other contact is connected to the positive output of the constant current module. The output of the analog multiplexer is connected to the control unit. The DC power supply outputs a constant current to the identification resistor to be detected through the constant current module. The socket body integrates LED indicator lights and a single buzzer corresponding to the number and position of the plug holes. The control unit is used to sequentially connect the individual concentric electrodes to the analog-to-digital conversion module, to obtain the digital quantity parsed by the analog-to-digital conversion module, to obtain the resistance value of the cylinder inserted into the corresponding insertion hole based on the digital quantity and the current value of the constant current module, to determine whether the obtained resistance value matches the resistance value pre-stored in the Flash memory, and to trigger a buzzer and illuminate the LED indicator of the correct insertion hole based on the matching result.

[0006] Furthermore, it also includes a wireless transmission module connected to the data acquisition module.

[0007] Furthermore, it also includes a storage module connected to the control unit and a terminal device connected to the wireless transmission module.

[0008] Furthermore, both the electrical contact socket and the concentric electrodes include positive and negative contacts.

[0009] Furthermore, the specific model of the analog multiplexer is CD74HC4067.

[0010] Furthermore, the data acquisition module and the wireless transmission module are integrated into a single chip, with the chip model being CC2340R5 or DA14531.

[0011] Furthermore, during resistor matching, the control unit determines that a correct match is achieved if the error between the measured resistance and the preset resistance of the corresponding hole in the Flash memory 32 is within a set range.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By using resistance coding instead of precision sensors, the hardware structure is simplified while ensuring recognition reliability and reducing system complexity. The LED indicator and buzzer feedback mechanism can synchronously indicate the correct position, avoiding confusion for young children due to ambiguous prompts. The entire device takes into account stability and maintainability, making it suitable for long-term, high-frequency use in educational settings. Attached Figure Description

Each cylinder 2 has a unique identification resistor 21 inside; the cylinder 2 is provided with an electrical contact socket 22 connected to the identification resistor 21; Each insertion hole 11 is provided with a concentric circular electrode 12 for insertion into an electrical contact socket 22. When inserted, it forms an electrical connection with the electrical contact socket 22. The electrical contact socket 22 includes a positive contact and a negative contact. The identification resistor 21 is connected to the contact on the electrical contact socket 22 by soldering. The wire is soldered to the concentric circular electrode by soldering, specifically by tin soldering. The electrical contact socket 22 is provided with a protective seat on the outside. The protective seat is fixed to the bottom of the cylinder by adhesive or heat fusion. The concentric electrode 12 is provided with a corresponding protective head on the outside. The protective head is installed in the insertion hole 11 by screws. The protective seat is used to insert into the protective head. One contact of the concentric electrode 12 is connected to the analog input pin of the analog multiplexer 6, and the other contact is connected to the positive output of the constant current module. The output of the analog multiplexer 6 is connected to the control unit 31. The DC power supply 34 outputs a constant current to the identification resistor 21 to be detected through the constant current module. Flash memory 32, pre-stores a unique resistor identifier and hole position number for each cylinder 2; DC power supply 34, used to power the system; The analog-to-digital conversion module 33 is connected to all the identification resistors 21 through wires, concentric electrodes 12, and positive and negative contacts of the electrical contact socket 22. It measures the voltage difference across the identification resistors 21 and converts the analog voltage measured by the resistance into a digital quantity. The socket body 1 integrates a buzzer 7 and an LED indicator 8 corresponding to the number and position of the plug holes 11. The control unit 31 compares the resistor-hole mapping relationship pre-stored in the Flash memory 32. When the control unit 31 determines that the resistance of the cylinder 2 inside the plug hole 11 is matched, the buzzer 7 is triggered to indicate the position and the LED indicator 8 next to the corresponding cylinder hole is lit. The control unit 31 is used to sequentially connect the individual concentric circular electrodes 12 to the analog-to-digital conversion module 33, and to obtain the digital quantity parsed by the analog-to-digital conversion module 33; to analyze the voltage value of the cylinder 2 inserted into each insertion hole 11, and to calculate the measured resistance value of the corresponding identification resistor 21 based on the preset constant current module current value and the analyzed voltage value according to Ohm's law, and to determine whether the measured resistance value matches the resistance value pre-stored in the Flash memory 32, and to trigger the buzzer 7 to prompt and light up the LED indicator 8 corresponding to the insertion hole 11 when the resistance values ​​match; It also includes a storage module 5 and a terminal device. The storage module 5 is connected to the control unit 31. The control unit 31 is used to store the operation record (the time corresponding to the correct resistor matching and the corresponding insertion hole 11) in the storage module 5. When connected to the terminal device, the control unit 31 sends the operation record to the terminal device.

[0018] See Figure 1 It also includes a wireless transmission module 4, which is connected to the data acquisition module 3; it is used to send data packets to the terminal device wirelessly. The wireless transmission module 4 uses the Bluetooth Low Energy protocol to establish a connection, and the terminal device receives the operation records in real time so that they can be displayed or analyzed when needed.

[0022] See Figure 1 The CD74HC4067 has 16 analog input / output channels (S0-S15), 1 common input / output channel (COM), and 4 digital address selection pins (A0-A3). Multiple concentric electrodes 12 are connected sequentially to the S0-S15 pins of the CD74HC4067. Then, the COM pin of the CD74HC4067 is connected to the ADC pin of the CC2340R5, and the address selection pins A0-A3 of the CD74HC4067 are connected to the GPIO pins of the CC2340R5. By controlling the 4-bit binary address code output by the A0-A3 pins, one of the 16 sensor channels is selected to be connected to the COM pin. The CC2340R5 uses its internal ADC to read the voltage value of the currently selected identification resistor 21 analog channel.

When inserted into the correct position, the LED indicator and buzzer provide an immediate confirmation signal; when inserted incorrectly, the LED indicator and buzzer feedback mechanism can synchronously indicate the correct position, avoiding confusion for young children due to ambiguous prompts. The entire device balances stability and maintainability, making it suitable for long-term, high-frequency use in educational settings.
