Abstract
The invention provides a remote power switch powered by a rechargeable battery. The remote power switch powered by rechargeable battery comprises a control circuit (KZ), a key switch (AJ), a TRIAC (tri-electrode AC (alternating current) switch) (TR) and a resistance load (RL). The control circuit is composed of a rechargeable battery (E), a travel switch (AJ-x), an optocoupler (TD), an isolating diode (D), a decode output (JS) and an infrared receiving tube (VD). The remote power switch powered by the rechargeable battery aims at providing a remote power switch in which: when the AJ is switched on, the travel switch can be switched on synchronously; when the AJ is switched off (the travel switch is switched off synchronously) and the TR is turned off, the control circuit can be powered by the rechargeable battery (the mains supply is not required to be changed into a low voltage), the D is isolated and RL is electroless; when the TR is turned on, a 5-volt power supply powers the control circuit and charges the E, the isolation of the D is cancelled; and codes and standby signals can be transferred between the control circuit and the RL. The remote power switch powered by the rechargeable battery can be used as the power switches of the infrared remote devices of televisions and STBs (set top box) and enable the standby power consumption to be reduced from three watts to 5 milliwatts powered by the E.

Description of drawings
Fig. 1 is the remote-controlled power switch schematic diagram with rechargeable battery power supply standby
Fig. 2 is that this switch is retrofitted to the connection principle enforcement figure in the set-top box
Embodiment
Be described further below in conjunction with the drawings and specific embodiments.
Fig. 1 Fig. 2 principle is identical, and circuit structure is slightly different.Fig. 1 is marked in decoding power-on pulse output circuit (J) and the circuit such as starting-up signal output circuit (S) and isolating diode (1D) in the solid box, the one, be convenient to draw supply pin and grounding leg, the 2nd, illustrate that the decoding integrated package (chip, module) of function in the solid box all can be used for this control circuit.
Take Fig. 2 as example, be the partial circuit of SD set-top box panel and the schematic diagram that has increased by two isolating diodes (3D, 4D) in the dotted line frame.R5, R6 are that the former machine that keeps moves back idol, biasing resistor, and R5, R6 tie point and VD supply pin path are pressed the X mark and disconnected, access 3D; VD output pin and coding input path are pressed the Y mark and are disconnected access 4D, travel switch (AJ-x) is fixed on key switch (AJ) other (guaranteeing that switch is synchronous), the circuit board that assembles is packed into one two-layer (one side is put No. 7 rechargeable battery another sides of three joints and put circuit board) in small plastic box, and be fixed on empty place in the cabinet, positive supply lead-out wire (comprising the lead-out wire that connects travel switch), ground outlet, coding lead-out wire, standby signal lead-out wire exact connect ion, again controllable silicon lead-out wire exact connect ion.
