Abstract
The utility model provides a 6-12V battery-powered low power remote controller supply circuit. The6-12V battery-powered low power remote controller supply circuit includes a power on-off control circuit, a key detecting circuit and a power supply self-locking circuit. The power on-off control circuit is composed of a triode, three resistors and a voltage regulator block, and achieves the power supply control of the circuit. An end of a key is connected with a resistor. Five outgoing ends of the key are connected respectively to the corresponding resistors and output ports. The output ports are connected respectively to output ports of a main control circuit. According to the utility model, the power consumption is almost zero when the key is not pressed, so that the service life of a battery can be greatly extended and the cost of the circuit is lowered.
Description
technical fieldthe utility model relates to a kind of remote control circuitry.
background technologycurrent, China's house has entered the Smart Home epoch, and intelligent radio is controlled and to be become wherein indispensable part, and traditional infrared remote control is inapplicable, and need to use can be through walls RF remote-controlled.And RF remote needs specific supply power voltage while using specific radio-frequency module, at this moment traditional remote controller power supply circuits have not met the supply power voltage requirement.The design can meet power supply in 6～12V scope.Owing to using powered battery, need to make the life-span long enough of battery, and battery in the market is difficult to meet this requirement.
the utility model content
The purpose of this utility model is to provide a kind of low power consumption remote controller power supply circuits of the use 6 ~ 12V battery electricity detected with button of remote controller.
The utility model comprises power supply on-off control circuit, key press detecting circuit and power supply latching circuit.The power supply on-off control circuit consists of triode one, resistance one, resistance two, three or three resistance of resistance and regulator block, realize the power supply control of circuit, the power supply of governor circuit is connected on the regulator block output, the positive pole of one end of resistance one, the emitter of triode one and 12V power supply connects together, and the other end of resistance one is connected to the base stage of resistance two, resistance three and triode one simultaneously; Resistance three other end connecting triode two collector electrodes; Resistance two other ends are connected with the button end; The collector electrode of triode one connects the input of regulator block.Key press detecting circuit consists of five buttons, corresponding with button five resistance and output port, one terminating resistor two of button, five of button go out end and receive respectively corresponding five resistance and five output ports, the negative pole that goes out to terminate to power supply the ground connection of five resistance, five output ports are connected with five output ports of governor circuit respectively.The power supply latching circuit consists of resistance four, resistance five, triode two and control end, resistance four and resistance five are received respectively the base stage of triode two, the control end of another termination governor circuit of resistance four, the emitter of another termination triode two of resistance five, then ground connection.
Circuit working process: after button is pressed, the control section switched on power makes power supply transistor one conducting, at this moment regulator block has just had voltage, and regulator block work is exported suitable stable voltage and powered to governor circuit, after working on power, gives immediately governor circuit power supply self-locking control end high level, make triode two conductings, and make triode one keep conducting, even at this moment button disconnects, triode one is also conducting, thereby makes the self-locking of powering.Then governor circuit obtains the state of button by detecting IO mouth low and high level, as is high level, illustrates that the button of this IO mouth correspondence is pressed, and governor circuit carries out corresponding operating according to the key information obtained.After operation completes, governor circuit is set to low level by control end, triode two cut-off, and as button now disconnects, triode one will end so, and whole system is de-energized, and so far circuit working completes.Due to triode one not conducting under usual state, the electric current of battery output equals the collector electrode of triode one-emitter reverse saturation current
i cEO,
i cEOvery very little, so the power consumption of whole circuit just can be ignored.
The utility model circuit, in the situation that the power consumption that button is not pressed is almost nil, make the working life of battery to extend widely, and the cost of circuit is very low.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Circuit in battery and governor circuit access dotted line frame as shown in Figure 1, can be divided into power supply on-off control circuit, key press detecting circuit and power supply latching circuit by function, the power supply on-off control circuit consists of triode Q1, three resistance R 1, R2, R3 and regulator block LM1 the power supply on-off control circuit, realize the power supply control of circuit, the power supply of governor circuit is connected on the output of regulator block LM1.Key press detecting circuit is by button S1 ~ S5 and resistance R 6 ~ R10 and five output ports formations, and five output ports are connected to the output port key1 ~ key5 of governor circuit.Key press detecting circuit links together with the power supply on-off control circuit by R2.The power supply latching circuit consists of R4, R5, triode Q2, control end Power_cn, and the power supply latching circuit is connected with the power supply on-off control circuit by R3.
The type selecting of regulator block is selected according to the supply power voltage of governor circuit, and the pull down resistor R6 ~ R10 of button makes the appropriate adjustments according to the operating voltage of MCU, and its ability to bear that is no more than the IO mouth is got final product.The IO mouth of the control of governor circuit power supply self-locking is connected to the input Power_cn of latching circuit, the IO mouth detected for button in MCU is connected to the output Key1 ~ Key5 of key press detecting circuit, the power supply of governor circuit is connected to the regulator block output of the bitterly disconnected control circuit of power supply.
