Abstract
The invention relates to an infrared remote control device for interfering TV radio frequency signal. The device includes infrared remote control emitter, infrared remote cotnrol receiver, circuitry box of TV radio frequency signal. Winding of relay in the circuitry box is connected to controlled current outputted from infrared remote control receiver. One end of switch contact points is connected to circuit of radio frequency source is the box; the other end is connected to TV radio frequency signal wire outputted to TV set. With power supply of infrared remote control emitter being closed or opened, the infrared receiving head receives or does not receive the infrared signal respectively. Accordingly, the relay contact points is closed or opened, at that time the ratio frequency signal wire is through or break off so as to interfer TV ratio frequency signal by using infrared remote control device.
Description
The present invention relates to a kind of device of infra-red remote control interfering TV RF signals.
The television set operate as normal must have good radiofrequency signal.There is miscellaneous device that can make television set receive the normal radio frequency signal home and abroad at present, as television receiving antenna, radio frequency signal amplifiers etc.It is investigated does not newly still have a kind of device of infra-red remote control interfering TV RF signals now, may with thought in the past that disturbing radiofrequency signal was that unhelpful cause is relevant.The present invention proposes this kind device, and TV RF signals is carried out Interference Control, unfavorable becomes favourablely it, is used.
The device that the purpose of this invention is to provide a kind of infra-red remote control interfering TV RF signals is used for some particular range.
The object of the present invention is achieved like this: this device comprises infra-red remote control transmitter, infrared remote control receiver, TV RF signals circuit box.TV RF signals circuit box comprises relay, radiofrequency signal circuit, box.The coil of relay connects the controlled current flow that infrared remote control receiver spreads out of, and relay switch contacts one end is linked into the radio-frequency signal source circuit in the box, and the other end connects the TV RF signals circuit that outputs to television set.
Infrared remote control receiver is with TV RF signals circuit box or separate or be integrated and be called infrared remote control receiver TV RF signals circuit box.Infrared receiving terminal DOL Data Output Line in the infrared remote control receiver meets a triode BG
1Base stage, its collector electrode meets another triode BG
2Base stage, triode BG
2The coil of collector connecting relay with it as load.When connecting the power supply of infra-red remote control transmitter, send Infrared, the infrared receiving terminal DOL Data Output Line level in the infrared remote control receiver TV RF signals circuit box reduces, triode BG
1By, another triode BG
2Conducting, relay gets electric, the relay switch contacts closure, and the radio-frequency signal source circuit that is connected in the access on the relay switch contacts links to each other with the radio-frequency line that outputs to television set, this moment, the radiofrequency signal circuit was unobstructed, and television set just can be received good TV RF signals.When disconnecting the power supply of infra-red remote control transmitter, do not send Infrared, the DOL Data Output Line current potential of infrared receiving terminal raises in the infrared remote control receiver TV RF signals circuit box, triode BG
1Conducting, another triode BG
2End, relay electric-loss, relay contact is opened, and this moment, the radiofrequency signal circuit opened circuit, and television set just can not be received good radiofrequency signal.
The infrared remote controller for interfering TV RF signals that the present invention relates to is because use the infra-red remote control mode, and the radiofrequency signal dependable performance is disturbed in simple in structure, remote control.
Concrete grammar and structure are provided by following embodiment and accompanying drawing thereof.Accompanying drawing 1 is the infra-red remote control transmitter circuit diagram, and it makes oscillator by a slice CMOS type 4 two output NAND gate integrated package 74HC00: accompanying drawing 2 is infrared remote control receiver circuit diagrams; Accompanying drawing 3 is connection layouts of the interior radio frequency signal line of TV RF signals circuit box (8) (9) (10), relay (6) and infrared remote control receiver; Accompanying drawing 4 is TV RF signals circuit box ((8) schematic diagrames.When connecting the infra-red remote control transmitter power supply, the oscillator vibration in the CMOS 74IIC00 integrated package (1), infrarede emitting diode (2) sends infrared signal.DOL Data Output Line became low level after the infrared receiving terminal of infrared remote control receiver (3) received infrared signal, triode BG
1(4) the base potential step-down and end, triode BG
2(5) base potential raises and conducting, relay (6), relay contact (7) closure, being connected in radio-frequency signal source circuit (9) that inserts on the relay contact and the radiofrequency signal circuit (10) that outputs to television set links to each other, this moment, the radiofrequency signal circuit was unobstructed, and television set just can be received good TV RF signals.The oscillator failure of oscillations when disconnecting the power supply of infra-red remote control transmitter in the integrated package (1), infrared light-emitting diode (2) stops to launch infrared signal.DOL Data Output Line did not become high level after infrared receiving terminal (3) received infrared signal, triode BG
1(4) conducting, another triode BG
2(5) end, relay (6) dead electricity, relay contact (7) is opened, and radiofrequency signal circuit (9) this moment (10) opens circuit, and television set just can not be received good TV RF signals.
Claims (3)
1, a kind of device of infra-red remote control interfering TV RF signals, it is characterized in that comprising infra-red remote control transmitter, infrared remote control receiver, TV RF signals circuit box, TV RF signals circuit box comprises relay (6), radiofrequency signal circuit (9) (10), box (8): the coil of relay (6) connects the controlled current flow that infrared remote control receiver spreads out of, relay switch contacts (7) one ends are linked into the radio-frequency signal source circuit (9) in the box, and the other end connects the TV RF signals circuit (10) that outputs to television set.
2, device according to claim 1 is characterized in that the DOL Data Output Line of the infrared receiving terminal (3) of infrared remote control receiver meets a triode BG
1(4) base stage, its collector electrode meet another triode BG
