Description
Technical field
The utility model belongs to infrared ray applied technical field, is about a kind of Infrared remote controller property detector.
Background technology
Present various televisor, video recorder, video disc player, sound equipment, air-conditioning and electric fan, and the electrical equipment control such as automobile door lock all have employed infrared remote control technology easily.In these electrical maintenance processes, often run into the phenomenon of Infrared remote controller functional failure.How does is failure judgement in Infrared remote controller part, or fault occurs in household appliance signal receiving unit?
Detect the quality of Infrared remote controller, usually use transistor radio audiometry, but transistor radio can only receive the higher hamonic wave of infrared remote-controlled signal, because the infrared signal that Infrared remote controller sends is very faint, the effect detecting Infrared remote controller with transistor radio is very undesirable.Infrared remote controller property detector described in the utility model is specifically designed to and detects infrared remote controller and other ultrared products, as long as judge whether Infrared remote controller transmits infrared remote-controlled signal, by the flicker of red light emitting diodes highlighted in circuit whether, the performance of detected Infrared remote controller is very clear, it is technician when keeping in repair, and can repair Infrared remote controller quickly and accurately and provide conveniently.
Below describe the relevant technologies content that Infrared remote controller property detector described in the utility model is involved in implementation process in detail.
Utility model content
Goal of the invention and beneficial effect: the quality detecting Infrared remote controller, usually use transistor radio audiometry, but transistor radio can only receive the higher hamonic wave of infrared remote-controlled signal, because the infrared signal that Infrared remote controller sends is very faint, the effect detecting Infrared remote controller with transistor radio is very undesirable.Infrared remote controller property detector described in the utility model is specifically designed to and detects infrared remote controller and other ultrared products, as long as judge whether Infrared remote controller transmits infrared remote-controlled signal, by the flicker of red light emitting diodes highlighted in circuit whether, the quality of detected Infrared remote controller is very clear, it is technician when keeping in repair, and can repair Infrared remote controller quickly and accurately and provide conveniently.
Circuit working principle: Infrared remote controller property detector circuit is made up of 6V direct supply, IR signal reception and infrared signal amplifying circuit IC1, display circuit.After connecting 6V direct supply, direct supply pilot lamp green LED LED2 is lit, Infrared remote controller is aimed at the Signal reception window of Infrared remote controller property detector, when pressing Infrared remote controller presses arbitrarily a key, after IR signal reception head and infrared signal amplifying circuit IC1 receive the modulation of infrared rays pulse that Infrared remote controller sends, the lower square-wave pulse signal of a frequency is produced through demodulation, it comprises telecommand information, at this moment the highlighted red light emitting diodes LED1 of detection display pilot lamp can glimmer, and illustrates that this Infrared remote controller performance is normal.If highlighted red light emitting diodes LED1 flicker free is luminous or Chang Liang, illustrate that this Infrared remote controller has fault.
Technical scheme: Infrared remote controller property detector, it comprises 6V direct supply, direct supply indicating circuit, IR signal reception and signal amplification circuit IC1, test result display circuit, it is characterized in that:

The technical parameter of components and parts and selection requirement
The integrated IR signal reception of IC1 and infrared signal amplifying circuit, can select the Receiver of remote control color tv, and its model is HS0038, and it is 3 pins, the 1st pin connection circuit ground GND, the 2nd pin connection circuit positive pole VCC, and the 3rd pin is signal output part;
D1 is switching diode, and the model selected is 1N4148;
LED1 is light emitting diode, selects the highlighted red light emitting diodes of ￠ 5mm;
LED2 is light emitting diode, selects ￠ 5mm green LED;
The resistance of resistance R1 is 620 Ω;
6V direct supply can use the common MnZn dry cell of 4 joint 5#.
Circuit production main points, circuit debugging and using method
Because the circuit structure of Infrared remote controller property detector is fairly simple, as long as the electronic devices and components performance generally selected is intact, and the components and parts annexation to specifications in accompanying drawing is welded, physical connection line and welding quality are through carefully checking correctly, and circuit of the present utility model does not substantially need to carry out debugging and can normally work;
Through test: in 6V DC power supply, stand-by operation electric current < 1.0mA, when receiving Infrared remote controller and sending infrared signal, complete machine working current is about 22mA, receives the coverage >=5m of infrared signal.
Circuit components layout of the present utility model, circuit structure design, its shape and size etc. of outward appearance are not all gordian techniquies of the present utility model; because not affecting the utility model specific implementation process; neither the claimed technology contents of the utility model, therefore do not illustrate one by one in the description.
