[0024] Example 1 See also Figure 1 , Figure 1It is a module schematic diagram of the intelligent education system of Example 1 of the present invention. The intelligent education system of the present invention includes a host computer 1 and an educational robot 2 connected to the host computer 1 by signal. The educational robot 2 is the assembly-type educational robot based on magnetic connection of the present invention. The educational robot 2 includes a robot body 21, and a plurality of peripherals 22 installed on the robot body 21 by magnetic connection. Students can freely install designated peripherals 22 on the robot body 21, so that the educational robot 2 has the designated functions required by the students. The robot body 21 can identify the installed peripherals 22 and transmit the peripheral information to the host computer 1. The host computer 1 displays relevant guidance information according to the peripheral information, thereby guiding students to independently build the educational robot 2.

[0025] In one embodiment, the educational robot 2 is an intelligent car, the robot body 21 is the car body, and the peripherals 22 include but are not limited to camera modules, microphone modules, speaker modules, vacuum cleaner modules, LED modules, infrared sensor modules, etc. When the student installs the camera module and the vacuum cleaner module on the car body, and writes the relevant program for automatically finding the way and controlling the start and stop of the vacuum cleaner module according to the image captured by the camera module, the intelligent car can have the function of a sweeping robot. When the student installs the microphone module and the speaker module on the car body, and writes the relevant program for playing music according to the voice data collected by the microphone module, the intelligent car can have the function of an intelligent speaker. In the above manner, students can freely install the specified peripherals 22 on the robot body 21, so that the educational robot 2 has the specified functions required by the students. In other embodiments, the educational robot 2 is not limited to the form of an intelligent car, but can also be other forms such as geometric, human, animal, and architectural. The present invention does not limit the specific form of the educational robot 2.

[0026] After the students install the peripherals 22 on the robot body 21, they also need to write the corresponding program code to enable the educational robot 2 to have the corresponding functions of the peripherals 22. In the traditional education model, the teacher introduces the relevant knowledge and usage methods of the peripherals to the students and guides the students to write program codes. The students need to rely on the teacher's explanation to complete the construction of the educational robot and cannot take the initiative. In order to solve the problem that students cannot take the initiative, the robot body 21 of the present invention can identify the installed peripherals 22 and transmit the peripheral information to the host computer 1; the host computer 1 displays relevant guidance information based on the peripheral information, thereby guiding the students to independently build the educational robot 2. The relevant guidance information displayed by the host computer 1 includes but is not limited to the basic introduction of the peripherals, working principles, usage methods and program writing tutorials. By consulting the relevant guidance information, students can independently write program codes without relying on the guidance of teachers.

[0027] See also Figure 2-3 , Figure 2 This is a schematic diagram of a module of an educational robot according to Embodiment 1 of the present invention. Figure 3 This is a schematic diagram of the structure of the first magnetic attraction module and the second magnetic attraction module in Example 1 of the present invention.

[0028] Specifically, the peripheral device 22 is provided with: a peripheral circuit board 221 and a first magnetic attraction module 222. The peripheral circuit board 221 is provided with a power supply input terminal, a ground terminal, an A signal transmission terminal and a B signal transmission terminal. The first magnetic attraction module 222 is arranged on the outer surface of the peripheral device 22, and is provided with a first VCC contact VCC1, a first GND contact GND1, a first A signal contact CHA1, a first B signal contact CHB1 and a first strong magnet 222a. The first VCC contact VCC1 of the first magnetic attraction module is electrically connected to the power supply input terminal of the peripheral circuit board 221, the first GND contact GND1 is electrically connected to the ground terminal of the peripheral circuit board 221, the first A signal contact CHA1 is electrically connected to the A signal transmission terminal of the peripheral circuit board 221, and the first B signal contact CHB1 is electrically connected to the B signal transmission terminal of the peripheral circuit board 221.

[0029] Specifically, the robot body 21 is provided with: a robot circuit board 211 and a plurality of second magnetic modules 212. The robot circuit board 211 is provided with a power supply output terminal, a ground terminal, and a plurality of A signal transmission terminals and a plurality of B signal transmission terminals. Each of the second magnetic modules 212 is arranged on the outer surface of the robot body 21, and is provided with a second VCC contact VCC2, a second GND contact GND2, a second A signal contact CHA2, a second B signal contact CHB2 and a second strong magnet 212a. The second VCC contact VCC2 of the second magnetic module is electrically connected to the power supply output terminal of the robot circuit board, the second GND contact GND2 is electrically connected to the ground terminal of the robot circuit board 211, the second A signal contact CHA2 is electrically connected to an A signal transmission terminal of the robot circuit board 211, and the second B signal contact CHB2 is electrically connected to a B signal transmission terminal of the robot circuit board 211.

[0030] The positions of the first VCC contact VCC1, the first GND contact GND1, the first A signal contact CHA1, the first B signal contact CHB1, and the first strong magnet 222a of the first magnetic attraction module 222 correspond to the positions of the second VCC contact VCC2, the second GND contact GND2, the second A signal contact CHA2, the second B signal contact CHB2, and the second strong magnet 212a of the second magnetic attraction module 212. The polarities of the first strong magnet 222a and the second strong magnet 212a are opposite.

[0031] When the first magnetic attraction module 222 and the second magnetic attraction module 212 are close to each other, the first strong magnet 222a and the second strong magnet 212a are attracted to each other, causing the first VCC contact VCC1, the first GND contact GND1, the first A signal contact CHA1, and the first B signal contact CHB1 to be connected to the second VCC contact VCC2, the second GND contact GND2, the second A signal contact CHA2, and the second B signal contact CHB2 respectively. At this time, the power supply output end of the robot circuit board 211 is connected to the power supply input end of the peripheral circuit board 221 through the second VCC contact VCC2 of the second magnetic module 212 and the first VCC contact VCC1 of the first magnetic module 222, thereby powering the peripheral circuit board 221; the grounding end of the robot circuit board 211 is connected to the grounding end of the peripheral circuit board 221 through the second GND contact GND2 of the second magnetic module 212 and the first GND contact GND1 of the first magnetic module 222, thereby providing a grounding end for the peripheral circuit board 221.

[0032] The A signal transmission end of the robot circuit board 211 is connected to the A signal transmission end of the peripheral circuit board 221 through the second A signal contact CHA1 of the second magnetic module 212 and the first A signal contact CHA1 of the first magnetic module 222, forming an A signal transmission channel. The B signal transmission end CHB2 of the robot circuit board 211 is connected to the B signal transmission end of the peripheral circuit board 221 through the second B signal contact CHB2 of the second magnetic module 212 and the first B signal contact CHB1 of the first magnetic module 222, forming a B signal transmission channel. The peripheral 22 and the robot body 21 perform dual-channel bidirectional data transmission through the A signal transmission channel and the B signal transmission channel.

[0033] In this embodiment, the number of the first strong magnet 222a and the second strong magnet 212 are both 2; the two first strong magnets 222a are respectively located at the left and right ends of the first magnetic attraction module 222, and the two second strong magnets 212a are respectively located at the left and right ends of the second magnetic attraction module 212. In other embodiments, the number of the first strong magnet 222 and the second strong magnet 212 may not be 2, and the positions are not limited to the left and right ends, as long as "when the first strong magnet and the second strong magnet are attracted, the first VCC contact, the first GND contact, the first A signal contact, and the first B signal contact are respectively connected to the second VCC contact, the second GND contact, the second A signal contact, and the second B signal contact".

[0034] In this embodiment, the second magnetic module 212 is further provided with a vertical post socket 212b. The vertical post socket 212b is arranged on a side of the second magnetic module 212 close to the inside of the robot body 21. The second VCC contact VCC2, the second GND contact GND2, the second A signal contact CHA2, and the second B signal contact CHB2 of the second magnetic module 212 are electrically connected to the vertical post socket 212b through printed wires. The power input terminal, the ground terminal, the A signal transmission terminal, and the B signal transmission terminal of the robot circuit board 211 of the robot body 21 are electrically connected to the vertical post socket 212b through flat cables. In other words, the power input terminal, the ground terminal, the A signal transmission terminal, and the B signal transmission terminal of the robot circuit board 211 of the robot body 21 are electrically connected to the second VCC contact VCC2, the second GND contact GND2, the second A signal contact CHA2, and the second B signal contact CHB2 of the second magnetic module 212 through flat cables, vertical post sockets, and printed wires.

[0035] In this embodiment, the first magnetic module 222 and the second magnetic module 212 are respectively provided with a first protrusion (not shown) and a second protrusion (not shown) whose positions and shapes match each other. When the first magnetic module 222 and the second magnetic module 212 are connected by suction in the correct direction, the first protrusion and the second protrusion are normally engaged; when the first magnetic module 222 and the second magnetic module 212 are connected by suction in the wrong direction, the first protrusion and the second protrusion cannot be normally engaged. Students can intuitively judge whether the peripheral is installed in the normal direction by feeling the feel of the first protrusion and the second protrusion when they are engaged, thereby improving installation efficiency.

[0036] In this embodiment, the robot body 21 identifies the peripheral information through I2C communication with the peripheral 22. Specifically, the A signal transmission channel serves as the data bus SDA of the I2C communication, and the B signal transmission channel serves as the clock bus SCL of the I2C communication, so that the robot body 21 and the peripheral 22 can perform bidirectional I2C communication. When the peripheral 22 is installed on the robot body 21, the peripheral 22 sends the peripheral information (such as the I2C slave address) that can characterize the type of the peripheral to the robot body 21 through I2C communication, and the robot body 21 forwards the peripheral information to the host computer 1, so that the host computer 1 displays relevant guidance information according to the peripheral information, thereby guiding students to independently build the educational robot 2.

[0037] Example 2 See also Figure 4 , Figure 4 This is a schematic diagram of the modules of the peripheral device according to the second embodiment of the present invention.

[0038] The difference between Example 2 of the present invention and Example 1 is that the robot body 21 identifies the peripheral information through the gate circuit on the peripheral circuit board 221 of the peripheral 22.

[0039] Specifically, the peripheral circuit board 221 of the peripheral device 22 includes: a gate circuit, a digital-to-analog converter DAC, a peripheral main control chip MCU and an analog switch S1. The outer surface of the peripheral device 22 is also provided with: a monitoring switch S2 and a monitoring indicator LED1.

[0040] The gate circuit fixedly outputs a preset binary digital number for characterizing the type of the peripheral device. The digital-to-analog converter DAC is electrically connected to the gate circuit to convert the binary digital number output by the gate circuit into an analog monitoring signal.

[0041] The peripheral main control chip MCU is provided with an A signal transmission end and a B signal transmission end (i.e., the A signal transmission end and the B signal transmission end of the peripheral circuit board in Example 1) for transmitting working data. The B signal transmission end of the peripheral main control chip is directly connected to the first B signal contact CHB1 of the first magnetic attraction module 222.

[0042] The analog switch S1 is a 2-to-1 analog switch, whose two input ends are respectively connected to the A signal transmission end of the peripheral main control chip and the monitoring signal output end of the digital-to-analog converter DAC, and whose output end is connected to the first A signal contact CHA1 of the first magnetic attraction module 222. The analog switch S1 is controlled by the selection control signal sent by the peripheral main control chip MCU, so that its output end is connected to one input end in different situations.

[0043] The monitoring switch S2 is electrically connected to the peripheral main control chip MCU; when the student triggers the monitoring switch S2, the peripheral main control chip MCU receives the monitoring switch signal generated by the monitoring switch S2 being triggered, and sends a selection control signal to the analog switch S1 according to the monitoring switch signal.

[0044] The monitoring indicator LED1 is electrically connected to the peripheral main control chip MCU, and is used to indicate the state of the analog switch S1. When the analog switch S1 connects the first A signal contact CHA1 of the first magnetic suction module 222 to the monitoring signal output end of the digital-to-analog converter DAC, the monitoring indicator LED1 lights up; when the analog switch S1 connects the first A signal contact CHA1 of the first magnetic suction module 222 to the A signal transmission end of the peripheral main control chip MCU, the monitoring indicator LED1 goes out.

[0045] The analog switch S1 connects the first A signal contact CHA1 of the first magnetic module 222 to the A signal transmission terminal of the peripheral main control chip MCU by default. At this time, the robot body 21 normally obtains working data through the A signal transmission channel and the B signal transmission channel, and the monitoring indicator light is off by default.

[0046] The peripheral main control chip MCU, when the peripheral 22 is just powered on (i.e., when the peripheral 22 is just installed on the robot body 21), or when receiving the monitoring switch signal generated by the monitoring switch S2 being triggered, sends a selection control signal to the analog switch S1, so that the analog switch S1 switches state, and the first A signal contact CHA1 of the first magnetic suction module 222 is connected to the monitoring signal output end of the digital-to-analog converter DAC. At this time, the monitoring indicator LED1 lights up; the robot body 21 obtains the monitoring signal that can characterize the type of peripheral through the A signal transmission channel, and restores the corresponding binary digits by parsing the monitoring signal, and then identifies the peripheral information according to the binary digits, and finally forwards the peripheral information to the host computer 1.

[0047] For example, in one embodiment, the gate circuit of the peripheral 22 whose peripheral type is an infrared sensor includes: a first follower, a first inverter, a second follower, and a second inverter. The input ends of the first follower, the first inverter, the second follower, and the second inverter are all connected to the power input end of the peripheral circuit board 221 of the peripheral 21, and the output ends are binary digital output ends D0-D3 respectively. Obviously, when the power input end of the peripheral circuit board 221 of the peripheral 21 is powered on, the binary digital output ends D0-D3 of the gate circuit fixedly output the binary digital "0101", and the voltage of the monitoring signal corresponding to the binary digital is 5 units. The robot body 21 recognizes the voltage of the monitoring signal through the built-in analog-to-digital converter, and can restore the original binary digital "0101", and then judge that the peripheral 22 currently installed on the robot body 21 is an infrared sensor. After the robot body 21 transmits the peripheral information indicating that the peripheral type is an infrared sensor to the host computer 1, the host computer 1 can display the guidance information related to the infrared sensor. Those skilled in the art can preset different binary numbers for different peripheral types, and design the specific structure of the corresponding gate circuit according to the specific binary numbers.

[0048] The A signal transmission channel and the B signal transmission channel play the role of transmitting working data when the peripheral device 22 is not in the monitoring state and is working normally. In order to prevent the peripheral device 22 from transmitting the monitoring signal to the robot body 21, resulting in the long-term occupation of the working data transmission channel, in this embodiment, the output end of the digital-to-analog converter is connected to the first A signal contact 221 of the first magnetic module 222 through a 2-to-1 analog switch S1. Only when the peripheral device 22 is just powered on or the student manually triggers the monitoring switch S2, the connection between the output end of the digital-to-analog converter DAC and the first A signal contact CHA1 of the first magnetic module 222 is turned on. In other cases, the A signal transmission channel transmits working data normally.

[0049] The monitoring indicator LED1 is on, indicating that the analog switch S1 connects the first A signal contact CHA1 of the first magnetic module 222 to the monitoring signal output end of the digital-to-analog converter DAC, and the A signal transmission channel is in a state of transmitting a monitoring signal. The monitoring indicator LED1 is off, indicating that the analog switch S1 connects the first A signal contact CHA1 of the first magnetic module 222 to the A signal transmission end of the peripheral main control chip MCU, and the A signal transmission channel is in a state of normally transmitting working data. Students and teachers can intuitively understand the status of the analog switch and the A signal transmission channel by observing the monitoring indicator.

[0050] The present invention has the following technical effects: 1. The peripherals are installed on the robot body by magnetic connection, which makes disassembly and assembly in the classroom more convenient, and the interface is not easily damaged, and the service life is longer. 2. When the peripherals are successfully installed, the robot body and the host computer can automatically detect and identify the peripheral information, and automatically display the relevant guidance information. Students can complete learning and programming independently according to the relevant guidance information, without relying on the teacher's demonstration and guidance, and give full play to the students' initiative. 3. Teachers and developers can grasp the situation of each student building an educational robot based on the peripheral information monitored in real time, so as to carry out personalized customized teaching and development.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and the present invention is also intended to include these modifications and modifications.
