IoT teaching test box exercises users' practical abilities
IoT Teaching Experiment BoxIt is designed to meet the requirements of microcontroller experimental teaching in the new era of electronics, communication, electrical automation, and industrial automation, and to improve students' ability in microcontroller application design and innovation. It is a fully functional, fully documented, highly modular, and cost-effective microcontroller experimental teaching equipment.
The IoT teaching test box adopts a two-layer architecture of motherboard and expansion board. In addition to commonly used circuits such as keyboard, display, generation of switch values, indication of switch values, traffic lights, DC motor (speed measurement), stepper motor, relay output, audio amplification, RS232 interface, etc., which are integrated on the motherboard, all other functional modules such as CPU, PIO (parallel IO), AD/DA, RTC, I2C, sensors, communication, signal generator, MP3 and voice recording and playback are implemented through the expansion board.IoT Teaching Experiment BoxThe control signal lines of the functional modules are all connected by open DuPont wires, which ensures the freedom of circuit connection and facilitates users to design their own hardware connection schemes; On the other hand, it has enhanced users' practical and hands-on abilities.
The IoT teaching test box adopts a modular structure, where each module can complete the corresponding unit experiments in the complete communication system, and students can use the unit modules to construct a complete communication system for system experiments, which helps students understand the roles of various elements in the communication system; The experimental platform has arranged corresponding experimental content for important theoretical aspects involved in communication systems, such as basic circuits, terminal encoding and decoding, modulation and demodulation, and channel transmission. The IoT teaching test box includes both basic experiments and advanced experiments using new technologies and devices such as FPGA and DSP, thus completing a theoretical verification, comprehensive, and secondary development process of systematic learning from low to high. These experiments can promote students' understanding and mastery of the content of the course "Principles of Communication", and provide them with a comprehensive understanding of communication systems, current new technologies, and engineering implementation. The system adopts a flexible structure combining "motherboard+experimental module", which is convenient for schools to choose, customize, add functions, and upgrade hardware.
The IoT teaching test box adopts a structure of "bottom board+experimental module", which not only modularizes the circuit according to the experimental content and function, but also independently designs each module, making it easy to combine unit experiments and various single/duplex communication system experiments. The input and output signals of the experimental module are all opened with rivet holes, and the experimenter can connect and combine them according to the experimental needs to enhance their participation. Each experimental module is covered with organic glass for protection, which facilitates laboratory management. Important parameters in the experiment can be adjusted or set, making it easy for experimenters to analyze and compare. thingOnline teaching test boxIt can complete dozens of unit and system experiments, covering terminal coding and decoding, line coding and decoding, modulation and demodulation, fiber optics, mobile and other aspects. It has built-in function signal sources, digital signal sources, interfaces, computer interfaces, coaxial cable channels, two transceiver integrated optical terminal channels, audio power amplifiers and other functional modules.
