Abstract

The utility model belongs to an electronic control device, particularly a multifunction general remote control device which is especially suitable for a television and other electric appliances. The device comprises a transmitting part and a remote control part. The utility model is characterized in that the remote control device is composed of a casing, a front panel, a keyboard, a glass window, an infrared receiver, a digital display device, a working state indicator, a timing key, an electronic watch, a keyboard door, a handle, a ventilation hole, a power interface of a television, a tuner interface, an automatic channel searching interface, a horn interface, an audio input interface, a main printed circuit board, etc. The utility model has the advantages of independent structure and novelty and can serve as a novel household appliance matched with a complete machine.

Description

Multifunction general tele-controller

The utility model belongs to a kind of electronic-controlled installation, is a kind of general multifunctional remote controller that is specially adapted to television set and other household electrical appliances.

At present, the remote controller that is used for television set can be divided into " in the machine " and " machine is outer " two kinds of forms, and the former is a modified type, promptly need to change in a large number TV set circuit, more than 20 tie point arranged approximately, and each point needs to seek wiring point on the television set of different model, therefore must be by full-time technical staff's repacking.This kind repacking needs in the perforate of the front of television set infrared remote receiver to be installed, and this all has bigger expendable destructiveness to circuit, housing.Latter's (machine is outer) belongs to the reception frequency converter of similar video tape recorder more, needs the TV signal demodulation is modulated again, from the wireless television set of sending into.Because very big to the picture quality influence to the repeatedly change of signal, be not easy to power supply, volume remote control simultaneously, the machinery of existing product is stored can not extended channel, thereby can not realize multifunction remote-control.

For overcoming the deficiencies in the prior art, to realize multifunction remote-control, the utility model provides a kind of general multifunctional remote controller with unique products structure.

The utility model is not done any change to former machine circuit, keeps the integrality of former machine, have can be easy for installation voluntarily etc. characteristics.Simultaneously, independent structures can be used as the novel household appliance product supporting with complete machine again.

General multifunctional remote controller comprises radiating portion and remote control part, and remote controller is by housing (1), front panel (2), keyboard (3), windowpane (4), infrared remote receiver (5), digital show (6), operating state indication (7), timing key (8), electronic watch (9), keyboard door (10), handle (11), ventilation hole (12), TV set power interface (13), tuner interface (14), automatically seek platform interface (15), horn interface (16), audio input interface (17), main printed boards (18) etc. are formed (as Fig. 1,2, shown in 3).Its middle shell (1) forms a complete casing with front panel (2); Keyboard (3) is provided with 8 keys altogether, be that channel adds respectively, channel down, tuningly add, tuningly subtract, volume adds, volume down, wave band conversion, storage key; And keyboard door (10) is housed, a handle (11) is arranged on the keyboard door; Operating state indication (7) comprises mains switch indication, wave band indication and seeks the platform indication.Television set or other family are electrically interposed on the TV set power interface (13).

The utility model belongs to the multiple unit combination of circuits, has particularly connected the band form change-over circuit, to adapt to the tuning circuit of various band forms.The utility model has also connected and has added amplifier circuit for sound frequency signal, and the remote control that can be used for TV or other audio signal is amplified.Each element circuit calls by the microcomputer center and connection produces multiple function (as shown in Figure 4).The repertoire action is by keyboard or infrared remote receiver control.Infrared remote receiver is a high-gain, jamproof code amplifier, and it delivers to the microcomputer center with every instruction.When the external audio frequency signal was imported, the volume adjustment of any intensity can be sent in the center, was added to loudspeaker or audio amplifier through power amplification circuit output.

In the flyback of external television set, during automatic frequency control of video signal, send into through shaping and to seek the platform circuit automatically, scan fast by microcomputer center control all-channel, seek platform indicator light (being the wave band indication) and flash.Whenever seek in the fixedness holder that a radio station writes microcomputer automatically.The power supply of microcomputer also can be by clock, automatic open and close television set during to the scheduled time when electronic watch is walked.

The action at microcomputer center receives instruction by Keyboard Control or infrared remote receiver, and for example, when receiving the instruction of open and close television set, the mind-set TV set power is sent signal in the microcomputer, simultaneously with this device power connection, makes device all enter operating state.

Civil power (220V) offers computer power by rectifying and voltage-stabilizing, synthesizes the required working power in center with various voltages.

Tuning output is read the tracking signal of former data that write and automatic fine tuning and is sent into remote control output together from holder.The wave band data of center output forms " H " or serpentine circuit by circuit conversion.One the tunnel send the wave band indication, and another road is delivered to remote control output and received television set.

The action of this device can be sent the exercises instruction with infrared coding emitter (as shown in Figure 5), receives and identifies coding by infrared remote receiver, sends microcomputer to and carry out action when effective.For reliable in action, prevent to be disturbed and misoperation, coding is made up of initial code, primary key, end code, and when a certain command coding of reception, as when can not discerning initial code, microcomputer can not move.Pressing behind the M key digital the demonstration goes out, and when pressing a certain numerical key again, just the data of current TV station is write the center through information memory, and Here it is, and shellfish is examined in addressing.

The expanded function type circuit that it is main body that the utility model adopts extensive special-purpose single chip microcomputer combines the multiple unit circuit together, and the formation structure is independent, novel, multi-functional household remote device.This device adapts to the TV remote-control of various models, only connects six roots of sensation line and gets final product, and it is quite convenient to install, and primary circuit is not done any change.Adjust circuit owing to connected digital automatic frequency, make image be in optimum state.The disconnected formula circuit of power down protection and complete shut-down is protected television set and home appliance effectively.The utility model has been realized multifunction remote-controls such as power supply, channel, volume, image, times.
