This invention discloses a microscopic interactive teaching terminal and its control method based on dual-
process isolation, specifically relating to the fields of educational
informatization and embedded systems technology. It includes a hardware layer and a
software layer: the hardware layer includes a main control
chip, an
image sensor, a display screen, a
wireless communication module, a storage module, and a
power management module. The main control
chip is configured as a Hisilicon Hi3516DV300 / 500. This invention completely decouples display and upload processes, resulting in high
system stability. The two processes run independently; the
crash of one process does not affect the other, and the
daemon process can automatically recover, ensuring continuous
system availability. This invention features rapid switching response, optimized network resources, and an independent upload process that can be flexibly scheduled according to teacher instructions, supporting multi-channel
concurrency without affecting the reception and display of broadcast streams. This invention has strong applicability and can be widely applied to various interactive teaching terminals based on embedded platforms, especially suitable for microscopic teaching scenarios with high real-time requirements.
