Abstract
The invention discloses a screen door control system based on dual-core control. The system comprises a microcontroller, a motor, a transmission mechanism and a door. A master control chip in the microcontroller comprises a MCU (micro control unit) chip and a DSP (digital signal processor) chip. The MCU chip and the DSP chip detect external signals at the same. The DSP chip reports the signals to the MCU chip through a universal serial bus. The MCU chip compares the signals, executes signal actions if the signals are consistent, and pends if the signals are not consistent. A peripheral motor module of the system connects to the motor through a security relay which is controlled by the MCU chip; once anomaly occurs, the MCU chip turns off the security relay; the DSP chip can control a speech module which is added to play speeches. The system has the advantages that dual-core control allows the screen door to operate stably and reliably and the overcurrent protection function and the speech module added allow the system to be more human.
