The intelligent power supply wiring board comprises a socket body in which a socket unit, an MCU controller, a power supply circuit connected with the MCU controller and a testing circuit are arranged; the testing circuit comprises an alternating-current mutual inductance circuit, a current amplifier and an AD sample circuit which are connected in sequence; the output end of the AD sample circuit is connected with the MCU controller; the alternating-current mutual inductance circuit is connected with the MCU controller and a power supply circuit by an off-on control circuit; the MCU controller is connected with a drive control circuit which is connected with a socket unit; and the MCU controller is also connected with a high frequency receiving circuit. On the basis of the principle that the working current of electrical products in normal work is different from that of the electrical products in a holding state, the power supply can be automatically cut off when the electrical product is in a holding state.
Description
(1) technical field
The utility model relates to a kind of power supply wiring board.
(2) background technology
Present many household electrical appliance such as computer monitor, water heater, air-conditioning etc., people usually forget and turn off power supply after use, and product is still being worked under holding state, the time one, long ten minutes took.But existing power supply wiring board does not have the function of cutting off the electricity supply automatically after the standby.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of supply socket in the prior art, the utility model provides a kind of intelligent power wiring board that can cut off the electricity supply automatically when electrical equipment is in holding state.
The technical scheme in the invention for solving the technical problem is: a kind of intelligent power wiring board, comprise pedestal, and be provided with socket unit in the described pedestal, the power circuit that is provided with the MCU controller in the described pedestal and is connected with described MCU controller; Also be provided with testing circuit in the described pedestal, described testing circuit comprises alternating current mutual inductance circuit, current amplification circuit and the AD sample circuit that connects successively, the output of described AD sample circuit is connected with described MCU controller, be connected by ON-OFF control circuit between described alternating current mutual inductance circuit and the described MCU controller, also be connected between described alternating current mutual inductance circuit and the described power circuit by described ON-OFF control circuit; Described MCU controller also is connected with Drive and Control Circuit, and described Drive and Control Circuit is connected with described socket unit, and described MCU controller also is connected with high frequency receiving circuit.
Further, described power circuit comprises power transformer and the voltage stabilizing circuit that connects successively, and described voltage stabilizing circuit is connected with ON-OFF control circuit with described MCU controller respectively.
Operation principle of the present utility model is: the operating current of electric equipment products when operate as normal is different at the operating current under the holding state with electric equipment products.Launch high-frequency signal by remote controller during use, receive by high frequency receiving circuit, command M CU controller opens ON-OFF control circuit, thus testing circuit is started working.The size of the alternating current sensing circuit senses operating current of testing circuit, and become current signal, this current signal is transferred to current amplification circuit current signal is amplified, then after the sampling of A/D sample circuit by MCU controller judgment processing.When electrical equipment is in holding state, the operating current of its operating current during with operate as normal is different, the alternating current mutual inductance circuit senses the current signal that produces after the variation of operating current and changes, and the MCU controller cuts off socket unit according to the conversion controlling and driving control circuit of current signal.
