Abstract:Because the electrical management and safety problems widely existed in dormitories, a chip microcomputer-based intelligent electrical controller which can automatically identify high-power electric appliances was developed. With the ability of prevent using banned high-power electric appliances, this design can be applied in dormitories, classrooms, and some other public places to reduce incipient fault of safety. Besides, it needs less electric energy to run than other systems with similar function. As have routine little power electric apparatus connect fashionable, person who change can exceed the establishing value twinkling of an eye in electric current, circuit Yes to supply power normally. And as have power above electric apparatus of establishing etc. at inserting circuit , instantaneous change amount of electric current exceed limit of having used to allow, it should be worth that the one-chip computer will cut the power. This work introduced the element of this system, operating principle of its main block and flowchart of its program.
