Abstract
The utility model relates to a standby non-power consumption universal electric apparatus socket which belongs to the application of SCM technology the field of control. The socket comprises a voltage comparator detecting device and a switch executive circuit and is characterized in that an input terminal of an SCM is connected with the voltage comparator detecting device, and an output terminal of the SCM is connected with the switch executive circuit. The voltage comparator is composed of a voltage transformer and a time-base circuit. A primary coil of the voltage transformer is connected with a load and a relay in series. A secondary coil of the voltage transformer is connected with an input terminal of the time-base circuit through a rectifier circuit and a divider circuit. The time-base circuit is connected into a monostable circuit, wherein an output terminal of which is connected with the input terminal of the SCM. The output terminal of the SCM is connected with the switch executive circuit which is composed of a switching tube and the relay. A normally-closed contact of the relay is connected with the primary coil of the voltage transformer and the load. After 30 second since the utility model detects an electric apparatus is in standby state, a power source of the electric apparatus is cut off. In addition, a light touch switch is pressed for recovering the power supply. Therefore, the utility model realizes the purposes of no standby power consumption and electric resource saving.
Description
Technical field the invention belongs to singlechip technology in the control Application for Field.
Before background technology the invention applying date, the general electronic corporation socket exists the drawback of standby power consumption owing to do not have standby powered-down function.
Summary of the invention purpose of the present invention just is to provide a kind of general electric socket without power consumption while standby (1),
The invention solves the technical scheme that its technical problem adopts: comprise voltage comparator checkout gear and switch executive circuit; The single-chip processor i/o input is connected with voltage comparator checkout gear output, and the single-chip processor i/o output is connected with the switch executive circuit.Described voltage comparator is made up of voltage transformer, time-base circuit, voltage transformer primary coil and load and relay polyphone, the secondary coil of voltage transformer is connected with the time-base circuit input by rectification circuit, bleeder circuit, time-base circuit is connected into monostable circuit, its output is connected with the single-chip processor i/o input, the single-chip processor i/o output is connected with the switch executive circuit that switching tube and relay are formed, and the normally-closed contact of relay and voltage transformer primary coil and load are in series.The single-chip processor i/o input is connected with touch-switch one end, connects positive source by resistance, other end ground connection.
