Intelligent Power Management System Based on ARM

This design is an intelligent power management system which is based on ARM, and it has two major functions: monitoring the current of the electrical equipment constantly and controlling on-off of the electrical equipment. This device will cut off the power immediately when the current of the electrical equipment is abnormal, in order to manage the electrical equipment and keep it safe. The chip of this design is LPC1857 which is from the NXP company. Collecting circuit transmits current value to LPC1857, then it will show on the superordination machine through the serial port after disposing by the processor. This design commendably satisfies the requirements of the aspects of system's intelligence, reliability and real-time.
