Abstract
An intelligent power strip comprises a shell, wherein main jacks and auxiliary jacks are arranged on the shell; main contacts and auxiliary contacts are arranged in a power strip body; the main contacts correspond to the main jacks; the auxiliary jacks correspond to the auxiliary contacts; an MCU controller and a power sampling circuit for sampling power are also arranged in the shell; the power sampling circuit is connected with the main contacts; a memory unit and a comparison unit are arranged in the MCU controller; the memory unit is used to store the power value detected by the power sampling circuit; the comparison unit stores an initial power value and compares the initial power value with the power value detected by the power sampling circuit; the power sampling circuit is connected with the memory unit through signals; the memory unit is connected with the comparison unit through signals; and the comparison unit is connected with the auxiliary contacts. The utility model can automatically shut down a slave control appliance when a master control appliance stands by, thus greatly saving electricity.
Description
(1) technical field
The utility model relates to a kind of socket.
(2) background technology
Existing socket does not have the branch of master control and secondary control, principal and subordinate's timesharing is arranged at electrical appliance, when the master control electric appliance standby, the electrical equipment that is subordinated to it cannot be cut off the electricity supply automatically (as computer and audio amplifier, computer is a master control electrical equipment, when computer was in holding state, audio amplifier can't be cut off the electricity supply automatically), therefore cause waste of electric energy.
(3) summary of the invention
For overcoming the above-mentioned deficiency of existing socket, the utility model provides a kind of smart jack with the secondary control output of master control control.
The technical scheme in the invention for solving the technical problem is: a kind of smart jack, comprise housing, described housing is provided with main jack and secondary jack, be provided with main sleeve and secondary sleeve in the described pedestal, described main sleeve is corresponding with described main jack, and described secondary jack is corresponding with described secondary sleeve;
Also be provided with the MCU controller in the described housing, be used for the power sample circuit that power is taken a sample, described power sample circuit is connected with described main sleeve, be provided with the memory cell that is used to store the detected performance number of described power sample circuit in the described MCU controller, prestore the initial gain value and the comparing unit of this initial gain value and the detected performance number of power sample circuit relatively, described power sample circuit is connected with described memory cell signal, and described memory cell is connected with described comparing unit signal; Described comparing unit is connected with described secondary sleeve.
Operation principle of the present utility model is: the plug of master control electrical equipment is inserted in the main jack, the plug of secondary control electrical equipment is inserted in the secondary jack, detect the power of master control electrical equipment by the power sample circuit, and detected performance number is stored to the memory cell of MCU controller, memory cell again will this detected performance number be delivered to the comparing unit of MCU controller, comparing unit compares this detected performance number with the initial gain value that prestores, if detected performance number is greater than initial gain value, then the MCU controller instructs secondary sleeve to connect, if detected performance number is less than initial gain value, then the MCU controller instructs secondary sleeve to disconnect.Because master control electrical equipment power when standby is less, thus master control electrical equipment when standby by the detected power of power sample circuit less than initial gain value, thereby then secondary thus sleeve disconnects and guarantees that master control electrical equipment secondary control electrical equipment when standby also cuts out.
The beneficial effects of the utility model are: realized that secondary control electrical equipment can cut out automatically when the master control electric appliance standby, therefore saved electric energy greatly.
(4) description of drawings
Fig. 1 is an outline drawing of the present utility model.
Fig. 2 is control principle figure of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of smart jack comprises housing 1, described housing 1 is provided with main jack 2 and secondary jack 3, be provided with main sleeve 4 and secondary sleeve 5 in the described pedestal 1, described main sleeve 4 is corresponding with described main jack 2, and described secondary jack 3 is corresponding with described secondary sleeve 5.
Also be provided with MCU controller 6 in the described housing 1, be used for the power sample circuit 7 that power is taken a sample, described power sample circuit 7 is connected with described main sleeve 4, be provided with the memory cell 8 that is used to store described power sample circuit 7 detected performance numbers in the described MCU controller 6, prestore the initial gain value and the comparing unit 9 of this initial gain value and power sample circuit 7 detected performance numbers relatively, described power sample circuit 7 is connected with described memory cell 8 signals, and described memory cell 8 is connected with described comparing unit 9 signals; Described comparing unit 9 is connected with described secondary sleeve 5.
During use, the plug of master control electrical equipment is inserted in the main jack 2, the plug of secondary control electrical equipment is inserted in the secondary jack 3, detect the power of master control electrical equipment by power sample circuit 7, and detected performance number is stored to the memory cell 8 of MCU controller, memory cell 8 again will this detected performance number be delivered to the comparing unit 9 of MCU controller, comparing unit 9 compares this detected performance number with the initial gain value that prestores, if detected performance number is greater than initial gain value, then the secondary sleeve 5 of MCU controller 6 instructions is connected, if detected performance number is less than initial gain value, then the secondary sleeve 5 of MCU controller 6 instructions disconnects.Because master control electrical equipment power when standby is less, thus master control electrical equipment when standby by power sample circuit 7 detected power less than initial gain value, thereby then secondary thus sleeve 5 disconnects and guarantees that master control electrical equipment secondary control electrical equipment when standby also cuts out.
