Abstract

The utility model discloses an easy found remote controller. No matter where the remote controller is, when the signals are within the effective range, the button of the controlled equipment is pressed, the remote controller can sound and light, and the user can immediately find the position of the remote controller. The circuit of the utility model comprises a remote controller circuit unit (1). The utility model is characterized in that the circuit of the easy found remote controller also comprises a receiving control unit (2) which uses the same power supply as the remote controller circuit unit and which comprises an amplifier BG1. The signals pass through a capacitor C2, a capacitor C3, a resistor R1, a resistor R2, and a capacitor C8 to the 15 pin of the integrated circuit IC02 and to the 3, 4 pins of the IC02, connected to the 18 pin of the output control integrated circuit IC01 through a resistor R12; the output signals of the 17 pin of the IC01 are connected to the 4 pin of the power amplifier integrated block IC03; the audio signals output through the 1 pin of the IC03 are added to the BC ends of the amplifier BG2, and the flicker output of the luminous diode DR1 and the audio frequency output of the loudspeaker LB are formed.

Description

Easily seek telepilot

Technical field:

The utility model is a kind of domestic electrical equipment remote controller that utilizes the photovoltaic principals design, belongs to electronic technology field.

Technical background:

Now a lot of household electrical appliance all adopt remote control, outside household electrical appliances body control system, again separately design have with household electrical appliances between adopt wireless mode to be connected controller, but be convenient to user's free operant and control household electrical appliances in effective range.And the telepilot volume is less, therefore arbitrarily places through using always later, and household electrical appliance have a variety of again, and corresponding controllers is a plurality of, causes inconvenience searching and mistaken when needing, and causes trouble to the user.

Summary of the invention:

The utility model purpose is to disclose a kind of easy searching telepilot.No matter telepilot is where, as long as in the effective range of signal, press the button on the controlled device, telepilot can pronounce luminous, and the user can find its position immediately.

The composition of the utility model circuit comprises a remote control circuitry unit (1), it is characterized in that its circuit is formed also comprises a reception control module (2) with common-battery source, remote control circuitry unit, described reception control module (2) comprises an amplifier BG1, its C utmost point and the E utmost point also connect capacitor C 1, the E utmost point between the ground through inductance L 1 and resistance R 1 and capacitor C 4 parallelled circuit ground connection, signal is through capacitor C 2, capacitor C 3 resistance R 1 and resistance R 2,15 pin of capacitor C 8 to receiving integrate circuit IC02,3 of IC02,4 pin, connect 18 pin of output control integrated circuit IC01 through resistance R 12, the 17 pin output signals of IC01 are connected to 4 pin of power discharging integrated block IC03, be added to the BC two ends of amplifier BG2 by the 1 pin output audio signal of IC03, form flashing and the audio frequency output of loudspeaker LB of light emitting diode DR1.

Description of drawings

Fig. 1 is the utility model theory diagram figure;

Fig. 2 is the utility model embodiment electrical schematic diagram;

The signal generator electrical schematic diagram of Fig. 3 for disposing on the matching used household electrical appliances of the utility model.

Embodiment:

Resistance R 1-R10 among Fig. 1, capacitor C 1-C11, inductance L 1, diode D1-D2 is the peripheral cell of receiving circuit.Duty and the receiving integrate circuit IC2 parameter of setting amplifier BG1 are provided with.R11-R14 is the peripheral cell that power amplifier is put ic chip 03.

Primary power is exported direct current through capacitor C 4 filtering through four rectifies among Fig. 2, when the K1 switch closure, supply with 18 pin direct supplys of IC04 signal generator, power connection is by 15, the 16 pin feedback sawtooth wave of IC04,17 pin output square wave, to amplifier tube BG1, produce control waveforms through resistance R 1, capacitor C 1 feedback and make the BG1 frequency stabilization at antenna L2 and capacitor C 3.

When seeking certain appliance controller, open this appliances power source, press the HK1 button.Signal generator work shown in Figure 2 produces the particular radiation signal.This signal is received by the circuit on the utility model telepilot, and light emitting diode DR1 flashes, and loudspeaker LB has the sound, and people are easy to find corresponding telepilot. and the utility model is simple and practical, the management of convenient household electrical equipment and operation.
