Abstract
The utility model discloses a signal tester for an infrared remote controller for household electric appliances. The tester is characterized in that a signal receiver is an infrared remote control receiver 1, a signal amplifier is a triode 2, and a signal indicator is a light emitting diode 3. A signal output base pin of the infrared receiver 1 is connected with a base electrode base pin of the triode 2 of the signal amplifier. An output base pin of the triode is communicated with the light emitting diode 3 of the signal indicator. The signal tester for an infrared remote controller for household electric appliances has the advantages that very simple circuit components and structures are adopted, and the testing judgment for the on-off state of all keys of the remote controller for household electric appliances is realized. The maintenance efficiency of a maintainer is improved.
Description
The utility model relates to the maintenance device equipment in the home appliance repair field, particularly helps the maintenance personal to judge each function key pick-up unit whether effectively of the infrared remote-control device of household electrical appliance.
Infrared domestic electrical equipment remote controller has obtained using widely in most of household electrical appliance, because it uses extensively, thing followed maintenance job has also just occurred.In the household electrical appliances maintenance job, often run into the problem of household remote disabler, fault how to judge inefficacy occurs in telepilot partly or occur in the receiving unit of household electrical appliances, and it is important just to seem.Generally be to prepare some dissimilar telepilots, so that the position of indirect detection failure judgement (promptly being telepilot or receiver) by the maintenance personal.Make maintenance job therefore become mixed and disorderly, influence normal maintenance job.Therefore, be necessary to design a kind of instrument, to change this disadvantageous situation.Therefore the purpose of this utility model has been proposed.
The purpose of this utility model is a kind of household electrical appliances Infrared remote controller signal supervisory instrument of design, solves the maintenance personal for the accurate decision problem of the abort situation of household electrical appliance and telepilot thereof.
The new purpose of this practicality realizes according to architectural feature described below, this device comprises a signal receiving device, a signal amplifying apparatus and at least one signal indicating device, it is characterized in that signal receiving device is an infrared remote-receiver 1, signal amplifying apparatus is a triode 2, and signal indicating device is a light emitting diode 3.The signal output pin of infrared receiver 1 is connected with the base stage pin of the triode 2 of signal amplifying apparatus, and the output pin of triode 2 is communicated with the light emitting diode of signal indicating device 3.The device of this spline structure has promptly been realized the purpose of this utility model.
The utility model has the advantages that, adopted very simple circuit component and structure, realized whether break-make contact good detection is judged for all buttons of domestic electrical equipment remote controller.Can help the maintenance personal to improve household electrical appliances effectively and repair efficient.
The following drawings explanation, accompanying drawing is structural circuit figure of the present utility model, the represented electronic component of each sequence number in the accompanying drawings is: 1, infrared receiver, 2, triode, 3,4, light emitting diode, 5, resistance one, 6, resistance two, 7, resistance three, 8, resistance four.
Below in conjunction with the embodiment in the accompanying drawing, describe structure of the present utility model and use in detail.With reference to accompanying drawing, this device comprises a signal receiving device, a signal amplifying apparatus and at least one signal indicating device, it is characterized in that signal receiving device is an infrared remote-receiver 1, signal amplifying apparatus is a triode 2, and signal indicating device is a light emitting diode 3.Light emitting diode 4 plays a power supply indication, judges by this light emitting diode 4 whether power supply is opened.In order to distinguish the indication of power supply indication and telepilot, can indicate luminotron to select red light power supply, signal indication luminotron is selected green light.The resistance four of sequence number 8 is pull-up resistors of light emitting diode 4.The resistance three of sequence number 7 is pull-up resistors of light emitting diode 3.The resistance one of sequence number 5 and the resistance two of sequence number 6 are base resistances.The signal output pin of infrared receiver 1 is connected with the base stage pin of the triode 2 of signal amplifying apparatus by the resistance three of sequence number 7, and the output pin of triode 2 is communicated with the light emitting diode of signal indicating device 3.
Provide one group of concrete parameter below to further specify.
Title model parameter
Infrared receiving terminal (IC2) TN02618 or TNP107443A etc.
Triode (BG1) A1015
Light emitting diode (D5 D6) LED
Resistance one (R1) 470 Ω
Resistance two (R2) 6.2 K Ω
Resistance three (R3) 100 Ω
Resistance four (R4) 2.0K Ω
Power supply direct current 5V
Above index value can fluctuate in the scope of ± 5%-10%.
During use, energized, after transformation rectification and stabilivolt IC1 arrangement, the output direct current.This moment, light emitting diode 4 should be lighted (red light), the indication power connection.The front end emission of the telepilot that needs repairing is partly aimed at the position of infrared receiver 1, press any button of telepilot, if light emitting diode 3 can sparkle (green light), this button non-fault on the telepilot is described, if it is not luminous, illustrate that then this button has fault, need to repair this button.This device can adapt to the various telepilots with domestic electric appliance of function of infrared remote control of common in the market various televisors, video recorder, video disc player, air-conditioning and electric fan.
