Problems solved by technology
[0003] To detect whether the infrared remote control is good or bad, a semiconductor radio is often used to test the audio, but the semiconductor radio can only receive the high-order harmonics of the infrared remote control signal, because the infrared signal sent by the infrared remote control is very weak, and the semiconductor radio is used to detect the infrared remote control. The effect is very unsatisfactory

The invention discloses a detector for properties of an infrared remote controller. Th detector is characterized by comprising a 6V direct-current power source, a direct-current power source indicating circuit, an infrared signal receiving and signal amplifying circuit and a test result display circuit, and the type of the infrared signal receiving and signal amplifying circuit IC1 is HS0038. The detector for the properties of the infrared remote controller, disclosed by the invention, is specially used for detecting an infrared remote controller and other infrared products; as long as whether an infrared remote control signal is transmitted by the infrared remote controller or not and whether a highlighted red light-emitting diode in the circuit twinkles or not are judged, the properties of the detected infrared remote controller are clear, and convenience is brought for technical staff for quickly and accurately repairing the infrared remote controller when the infrared remote controller is maintained.
Description
technical field [0001] The invention belongs to the field of infrared application technology, and relates to an infrared remote control performance detector. Background technique [0002] Now various TV sets, VCRs, DVD players, stereos, air conditioners and electric fans, and electrical appliances such as car door locks have all adopted convenient infrared remote control technology. In the process of repairing these electrical appliances, it is often encountered that the function of the infrared remote control fails. How to judge whether the fault is in the infrared remote control part or the fault occurs in the signal receiving part of the household appliances? [0003] To detect whether the infrared remote control is good or bad, a semiconductor radio is often used to test the audio, but the semiconductor radio can only receive the high-order harmonics of the infrared remote control signal, because the infrared signal sent by the infrared remote control is very weak, and ...
