The invention provides an onboard practical training platform for Internet-of-Things (IOT) teaching. The practical training platform comprises a practical training platform board; a power supply, a network wiring terminal, and a plurality of IOT practical training systems are installed on the practical training platform board. The network wiring terminal has a plurality of signal output terminalsthat are connected with corresponding signal input terminals in all IOT practical training systems correspondingly. And the power supply provides power for components in all IOT practical training systems. The practical training platform occupies a small area and can be maintained conveniently, so that the occupied space by the existing practical training platform like a sand table is saved substantially; the result is visual; cooperation with intelligent systems of different external members is realized; a real environment is simulated; the actual using effect can be experienced by changing the input parameters at the console; and the teaching effect of mapping to the material object by the theory and technology is improved.
