Abstract:

In order to achieve the goal of saving electricity, the intelligent electric meter suitable for colleges is designed, based on the MSP430 MCU (Micro Control Unit). Current is sampled by electricity solenoid. The IC card identification, keyboard and display the human computer interaction function make it not only a general intelligent electric meter, but also a meter with many users. The charging of period of time are suitable for the measures of restriction of electricity at college, which has a positive application prospect.

Key words: intelligent electric meter, college, MSP430 micro control unit (MCU), human computer interaction
