Described communication unit 22 is the integrated circuit of various types of communication mode; The various types of communication mode comprises wired communication mode, communication or power line carrier, PLC mode.
Describe below in conjunction with specific embodiments of the invention.
Local control mode: power line (live wire) links to each other with the live wire of load 11 through rocker switch 12, and rocker switch 12 all is fixed in the switch enclosure with electromagnet 23,24; Be in when rocker switch 12 in the situation of disconnection (referring to Fig. 1), press the A end of the button 12c perk of rocker switch, the dome 12d of rocker switch 12 slides into another side around back shaft 12h and along metal seesaw sheet 12e from one side, metal seesaw sheet 12e swings around supporting pin 12i, contact 12f contacts with contact 12g, the B end perk of rocker switch, the circuit of load 11 is changed into on-state from off-state; Be in when rocker switch 12 in the situation of connection (referring to Fig. 2), press the B end of rocker switch button 12c perk, the dome 12d of rocker switch 12 slides into another side around back shaft 12h and along metal seesaw sheet 12e from one side, metal seesaw sheet 12e swings around supporting pin 12i, contact 12f and contact 12g are separately, the A end perk of rocker switch button 12c, the circuit of load 11 is changed into off-state from on-state.Therefore, this locality is controlled to be traditional mechanical type rocker switch control mode.After the on off operating mode of load changes, judge that by voltage detecting circuit 13 whether load connect, and testing result is passed to control unit 14, then pass to remote control 20 by gateway device 18.
The Long-distance Control mode: remote control 20 at first by wireless router 19 access gateway devices 18, demonstrates the icon of each load and the on off operating mode of each load (state that is switched on or switched off that can represent with different colors load) at remote control 20; In the situation that load circuit disconnects (referring to Fig. 1), icon is shown as the information that load disconnects, touch this and load on icon on the remote control 20 (expression requires to connect load circuit), gateway device 18 sends the control unit 14 that goes code to intelligent switch by communication unit 22, control unit 14 is by the transient current drive magnet 23 of drive circuit 15, the movable core 23c of electromagnet 23 under the effect of electromagnetic field with secured core 23b adhesive, the process of this adhesive promotes the metal seesaw sheet 12e action of rocker switch 12 by push rod 23a, metal seesaw sheet 12e swings around supporting pin 12i, the dome 12d that is pressed in above the metal seesaw sheet slides into another side around back shaft 12h and along metal seesaw sheet from one side, contact 12f contacts with contact 12g, simultaneously the perk of the B of rocker switch button 12c end.Like this, just simulated staff and pressed rocker switch at the A of button 12c end, load circuit is changed into on-state from off-state.The state of rocker switch is passed to control unit 14 by voltage detecting circuit 13 with the connection information of load circuit after changing, and then passes to the state information that remote control 20(icon shows that load circuit is connected by gateway device 18).In the situation that load circuit is being connected (referring to Fig. 2), icon is shown as the state information that load is connected, touch this and load on icon (expression requires the disconnecting consumers circuit) on the remote control 20, gateway device 18 sends open command to the control unit 14 of intelligent switch by communication unit 22, control unit 14 is by the transient current drive magnet 24 of drive circuit 15, the movable core 24c of electromagnet 24 under the effect of electromagnetic field with secured core 24b adhesive, the process of this adhesive promotes the metal seesaw sheet 12e of rocker switch by push rod 24a, metal seesaw sheet 12e swings around supporting pin 12i, the dome 12d that is pressed in above the metal seesaw sheet 12e slides into another side around back shaft 12h and along metal seesaw sheet 12e from one side, contact 12f and contact 12g disconnect, simultaneously the perk of the A of rocker switch button 12c end.Like this, just simulated staff and pressed rocker switch at the B of button 12c end, load circuit is changed into off-state from on-state.The state of rocker switch is passed to control unit 14 by voltage detecting circuit 13 with the disconnection information of load circuit after changing, and then passes to the state information that remote control 20(shows that load circuit disconnects by gateway device 18).
After electromagnet 23 or 24 instantaneous operations are finished, magnetic field diminishes, electromagnet movable core 23c, 24c get back to initial position under the effect of electromagnet internal reset spring 23e, 24e, prepare action next time.
Technical scheme of the present invention also possesses following two kinds of variations:
Technical scheme one of changes (embodiment two): the moving seesaw-type intelligent switch changes electromagnet into pulling (referring to Fig. 6) to the promotion of rocker switch metal seesaw sheet 12e, in the technical program, the movable core 23c of electromagnet 23 and the instantaneous adhesive of secured core 23b have been equivalent to simulate staff and have pressed rocker switch at the B of button 12c end, and the moving seesaw-type intelligent switch is changed into off-state from on-state; The movable core 24c of electromagnet 24 and the instantaneous adhesive of secured core 24b have been equivalent to simulate staff and have pressed rocker switch at the A of button 12c end, and the moving seesaw-type intelligent switch is changed into on-state from off-state.
Two (embodiment three) of technical scheme variation: replace electromagnet 23, electromagnet 24(referring to Fig. 7 with a bidirectional electromagnet 25), bidirectional electromagnet is two electromagnet in itself.In the technical program, the movable core 25c of bidirectional electromagnet and the instantaneous adhesive of secured core 25b have been equivalent to simulate staff and have pressed rocker switch at the B of button 12c end, make the moving seesaw-type intelligent switch change into off-state from on-state; The movable core 25c of bidirectional electromagnet and the instantaneous adhesive of secured core 25d have been equivalent to simulate staff and have pressed rocker switch at the A of button 12c end, and the moving seesaw-type intelligent switch is changed into on-state from off-state.
Rocker switch among the present invention, electromagnet can outsourcings, also can customize as required.Calculate the size of the electromagnet coil number of turn and electrical current according to the required oscillatory forces of rocker switch metal seesaw sheet.Decide the stroke of the movable core of electromagnet according to the oscillating stroke of rocker switch metal seesaw sheet.It is pointed out that the restriction owing to installing space, the moving seesaw-type intelligent switch need take into full account the size of size.
