Identify the quality of the remote control:
If the remote control distance of the anti-theft system is too close or the remote control does not work at all, you should consider whether the remote control receiver circuit is faulty. To determine whether the remote control receiver is working normally, the commonly used methods are as follows.
① Put [5] the receiving antenna of the spectrum analyzer close to the receiver, and power on the anti-theft system (or remote control receiver). Wave-like (capacity-regulating) or inflated (adjusting-sensing) should be observed in the 200～400MHz frequency band. Spectrum waveform. If there is no response on the spectrum analyzer screen, the receiver circuit is faulty.
② Transmit the signal with the remote control, observe the output terminal (OUT) of the receiver with an oscilloscope, and the input terminal of the decoding circuit should have a pulse signal output. Because of the different data signals sent, the waveform is a pulse train with different combinations of width and narrow. If the waveform is abnormal or the waveform cannot be detected, it indicates that the remote control receiver is malfunctioning.
③Use an oscilloscope to observe the signal output end of the remote control receiver, and touch the antenna input end of the remote control receiver with a metal object. The oscilloscope should have a strong clutter response, otherwise it means that the receiver is malfunctioning.
④ Use the remote control to transmit the signal, and use the multimeter to measure the voltage at the output end of the signal. When the button of the remote control is pressed, the voltage at the output end should change. If there is no response, the receiver circuit is faulty.
